The Purchasing And Using Method Of Wood Engraving Machine

The wood engraving machine is mainly used for the processing of wood, and make it more beautiful, at present, there are many kinds of woodworking engraving machines on the market, and the quality and price of the products are also uneven. It’s necessary to select carefully when purchasing. Here are five points for purchasing the wood engraving machines.

1. Look at the size of the engraving machine.

The customer should select the model of the engraving machine and its power according to the needs of the business and the funding situation. Generally, the small-format engraving machine has 600mm×600mm and 600mm×900mm, and the feeding width is 700mm. The engraving two-color board is the most basic application of the small-format engraving machine, and the acceptance is very good. The price of the smaller engraving machine is similar to that of the engraving machine, but it is more troublesome and unnecessary waste when engraving the two-color board. The large-format engraving machine has 1200mm×1200mm, 200mm×1500mm, 1500mm×2400mm, 2400mm×3000mm. The engraving machine of the above models has a width of more than 1350mm. The size of plexiglass and PVC board on the market is now 1300mm× 2400mm, these models are suitable for customers who require large-format engraving machines.

2. Pay attention to the spindle motor of the engraving machine.

The spindle motor is an important component of the computer engraving machine, and its performance has a crucial influence on the performance of the computer engraving machine. Machining spindles are generally divided into two categories: precision machining spindles and high power cutting spindles.

The good machining spindle is characterized by low noise, high speed and height, and is suitable for processing particularly fine work pieces such as stamps, nameplates, badges and so on. Such motors are usually high-speed variable frequency motors with low power, typically below 250W. The disadvantage is that the ability to cut thick materials is poor and does not cut off thicker materials.

High-power cutting spindle, mainly used for cutting, high-power engraving, characterized by high power, strong cutting ability, especially suitable for cutting the universe, three-dimensional characters, of course, you can also make badges, nameplates, seals and so on. Such high-power spindles can be generally divided into brushless high-speed AC motors and brushed AC motors according to the characteristics of the motor. The main difference is: A, the brushless inverter motor has a high speed, and the shift range is 70060000 rpm, and generally there are The maximum speed of brush AC motor does not exceed 24000 rev / min: B, brushless variable frequency motor has high rotation precision, low wear and low noise, and the noise is much lower than brushed AC motor; C, brushless inverter motor has good blocking characteristics, due to There is a special current limiting circuit on the inverter. The short-time blocking will not burn the motor, and the brushed AC will burn out quickly when it is overloaded or blocked, and it cannot be repaired. D. Brushless inverter motor It adopts frequency conversion control technology to adjust speed. It is a professional-grade product with long service life. The manufacturer provides one-year free replacement. In the future, the motor can be maintained by replacing high-speed bearings. The brushed AC motor has a life of about 300 hours. The motor or motor carbon brush has to be replaced, so the carbon brush AC motor is usually not guaranteed for one day.

3. the selection of the control mode and speed of the engraving machine: the control mode can now be divided into three types:

A. All the calculation work is completed by computer control. When the engraving machine is working, the computer is in working state, and other typesetting work cannot be performed. This may cause the computer to malfunction and cause waste.

B. Using the control of the single-chip microcomputer, this controller can perform typesetting while the engraving machine works, but can not turn off the computer, which is actually equivalent to saving 7 computers, and reducing the waste caused by the computer's misoperation.

C. Using the USB port to transfer data, the system has a memory capacity of more than 32M. As long as you save the file, you can completely disconnect from the computer, turn off the computer, or perform other typesetting. This method greatly improves the working efficiency of the engraving machine.

4. Pay attention to its guide rails.

The large-format engraving machine must use a widened imported square guide rail, and its load capacity and precision retention ability are more than 30 times that of the circular guide rail, which ensures the high quality and high speed of the engraving machine.

5. the accuracy of the engraving machine. The small-format machine engraves 1mm Chinese characters, or the large-format engraving machine engraves 1.5mm small characters, which must be seen very clearly under the magnifying glass.

Development and application of Laser marker for bar code technology

The bar code technology was first produced in the 1920s and was born in the laboratory of Westinghouse. An inventor named George Kamud found it in the automatic sorting of postal documents, and every idea of the application of electronic technology at that time was very novel and surprised.

His original idea was to make a bar code mark on the envelope. The information in the bar code is the address of the addressee, just like today's postal code. For this reason, Kamud invented the earliest bar code identification. The design scheme is very simple, that is, one "bar" indicates the number "1", and two "bars" indicate the number "2", and so on. He then invented a bar code reading device consisting of basic components: a scanner (capable of emitting light and receiving reflected light); a method for determining the reflected signal strip and space, ie edge-positioning coils; and using the measurement results The method is the decoder.

The emergence of commodity bar codes is a new application of bar code technology in real life. The commodity bar code is a special symbol that converts the digital code representing the commodity information into parallel lines arranged by a set of rules. In 1970, the US grocery industry took the lead in using this bar code on food packaging carriers, which was extended to worldwide use. The commodity bar code is the "identity card" of the commodity, and is the "common language" in which the commodity is circulated in the international market.

Commodity bar codes are the basis for commercial modernization, and are the entry tickets for goods entering supermarkets and POS scanning stores. In the scanning store, When the customer purchases the goods and pays at the checkout counter, the cashier simply picks up the goods with the bar code on the stage equipped with the laser scanner, and quickly enters the number below the bar code into the computer, through inquiry and Data processing, the machine can immediately identify the product manufacturer, name, price and other product information and print out the shopping list. In this way, not only can the automatic management of sales, warehousing and ordering be realized, but also the sales information can be mastered by the manufacturer in time through the production, supply and sales information system. There are currently about 700,000 POS scanning stores in the world, and more than 1,000 POS scanning stores have been built in China. This type of POS store is growing at an alarming rate. In fact, bar code has become a necessary condition for goods to enter the supermarket. Commodity bar code is the only way for enterprises to improve their market competitiveness and expand their export. It is a prerequisite for realizing automation of production and circulation, and it is also a technology for manufacturers to adjust product structure in a timely manner. Guarantee. In recent years, many cities in China (such as Beijing, Shanghai, Fujian, etc.) have documented that all bar code-free goods must not enter the supermarket.

The major products of China Perfect Laser are divided into marking equipment and processing equipment. Marking equipment includes: laser marking machine, pneumatic marking machine, ink jet printer, sign stamping machine, etc. Processing equipment includes: laser engraving machine, laser welding machine, Laser cutting machine, plasma cutting machine, Mechanical engraving machine, etc., a total of 10 series, more than 100 models.

Purchasing skills and precautions for laser engraving machine

In recent years, with the rapid development of industrial science and technology, and the development and promotion of laser engraving machines in application technology, the production and sales of laser marking and engraving equipment have shown a good upward trend. There are various kinds of laser equipment available on the market, which can be summed up in the following products: laser welding, laser marking, sub-surface laser engraving, laser cutting, laser demonstration, laser drilling, laser plate making machine, laser medical treatment, laser cosmetic, laser heat treatment, laser printing and so on. They are the crystallization products of laser technology and software control technology, and bring vitality to modern industrial civilization. Therefore, in recent years, companies engaged in the development, manufacture, and sales of laser equipment and companies that represent foreign laser equipment have rapidly increased. Competition has also become increasingly fierce. So in this mixed laser engraving machine field, how to properly choose their own laser engraving machine is particularly important.

The first one is the accuracy of the laser engraving machine. High-precision laser engraving machines naturally attract people's attention. Therefore, the difference between laser engraving and traditional engraving equipment or manual engraving is high accuracy. Therefore, when selecting, we must pay more attention to the engraving accuracy. The higher the engraving accuracy, the better the engraving effect and the more satisfied the product and the customer.

The second thing is to know the size of the product you want to process. Choose the right laser engraving machine according to the actual size of the product you want to engrave, which is the choice of the working area of the laser engraving machine. For example, if the size of the product you want to engrave is 130cm*90cm, then you can choose the model with the engraving area 130cm*90cm.It's worth noting that the large-format engraving area does not mean that the machine is better. Because the price is very expensive, and some machines with poor quality have unstable laser output averages at various points on the large-format processing table, resulting in different depths of engraving products on the same table. Therefore, it is necessary to choose the proper engraving area machine.

The third thing is to know which industry you are doing. In the market, the engraving machines can be divided into two major categories: one is engraving non-metal material, the other is engraving metal material. The non-metal engraving machine use carbon dioxide laser tube, and metal engraving machine use YAG laser. Moreover, in addition to these two categories, there are many different types of engraving machines, such as laser welding machines, laser marking machines, laser engraving machines, laser demonstrators, laser drilling machines, and so on. Therefore, it is necessary to correctly choose the laser engraving machine according to the industry that they have done and the specific content carved in their own industry.

The fifth thing is the credibility and good after-sales service. This depends on the customer's understanding of the market and industry. After-sales service has a direct impact on the production efficiency. If the machine has a fault that cannot be solved, it can't work, which directly leads to production stop. Therefore, after-sales service is very important. Thus, when customers choose laser engraving machine products, they must actively understand and analyze the market, figure out which manufacturers produce better quality machines, and the credibility is guaranteed. Only when you have mastered these things, you can choose the best machine.

How a galvanometer works

I. The development process of laser marking:

The core of laser marking machine is control system and marking head. Therefore, they are constantly updated and progressed with the development of laser marking machines.

Since 1995, the field of laser marking machines has experienced the large-format era, the rotating mirror era, and the galvanometer era, its control mode also completed a series of evolution from software direct control to control of the upper and lower machines to real-time processing and time-division multiplexing. Nowadays, the emergence and development of semiconductor laser machines, fiber laser machines, and even uv laser machines pose new challenges to optical process control ------ the galvanometer-type laser marking head (galvanometric scanning system) is the latest product.

In 1998, large-scale application galvanometer scanning system in China began to come. The galvanometer, also known as ammeter, whose design idea completely follows the design method of the ammeter, the lens replaces the hands, and the signal of the probe is replaced by a computer-controlled DC signal of -5V—﹢5V or -10V—﹢10V to complete the predetermined action. Similar to the rotating mirror system, this typical control system uses a pair of foldback mirrors. The difference is that the stepper motor that drives this lens is replaced by a servo motor. In this control system, the use of position sensors and negative feedback loop design ideas to further ensure the accuracy of the system, the entire system scan speed and repeat positioning accuracy is up to a new level.

II. Laser scanning principle:

The galvanometer scanning marking head is mainly composed of an XY scanning mirror, a field lens, a galvanometer, and a computer-controlled marking software. The working principle is that the laser beam is incident on two mirrors (scanning mirrors), and the reflection angle of the mirror is controlled by a computer, the two mirrors can be scanned along the X and Y axes respectively, so as to achieve the deflection of the laser beam, so that the laser power spot with a certain power density moves on the marking material as required, leaving a permanent mark on the surface of the material, and the focused spot can be round or rectangular. The scanning mirror provided by the Wuhan Division of Nanjing Wavelength Optoelectronic Technology Co., Ltd. has a reflectance of 99.5% or more, and the size of each sheet is calculated based on the size of the laser beam. Compared to two-axis scanning mirrors, Y-mirrors generally have a larger size than X-mirrors, X-mirrors scan to Y-mirrors rather than directly to the object.

In the galvanometer scanning system, the vector graphics and text can be used. This method uses the graphics software of the computer to process the graphics, has the characteristics of high efficiency, good graphic accuracy and no distortion, which greatly improves the quality and speed of the laser marking machine. At the same time, the galvanometer marking can also adopt the dot matrix marking method, which is very suitable for on-line marking. According to different speeds of the production line, one scanning galvanometer or two scanning galvanometers can be used. Compared with the array marking described above, more dot matrix information can be marked, which has greater advantages for marking Chinese characters.

Galvanometer scanning marking machine has become a mainstream product because of the advantages of wide range of applications, can apply for vector marking and dot matrix marking, adjustable marking range, fast response speed, high marking speed, high marking quality, good optical path sealing performance, and strong adaptability to the environment. It is considered to represent the future development direction of laser marking machines and has broad application prospects.

Can laser marking machine be used for printing pictures?

It is very common for mobile phones to take photos. Everyone wants to permanently mark their own precious photos. At this time, you have to ask: Can a laser marker hit a photo?

To understand the concept of picture marking, pictures are bitmaps, and bitmaps have pixel dimensions and color values for each bit. Bitmap marking, converting color values into laser energy, which is power*time; pixel size, depending on field lens selection and image finesse requirements, large field lens, large laser spot, rough image, and image fineness Say the pixel dpi (dot per inch, the number of pixels per inch), the bigger the finer and slower, of course.

Generally imported optical fiber, the picture produced has a three-dimensional sense, because the laser power in real time is high, and the light spot is delicate. General side pump machinery, power adjustment and beam quality are poor, the picture is not good. Domestic optical fiber, centered.

Many people may not even know that it is possible to mark pictures with a laser marking machine. First of all, the fiber laser marking machine, fiber laser marking machine can be used to mark numbers, letters, text, pictures, two-dimensional codes, etc. . The object of action is metal and some non-metals such as hard plastic. Widely used in mobile power, mobile phone shell, aluminum oxide hit the black, tablet computers, rings, watches, sanitary ware, electronic components and other industries.

Of course, for the quality of the photo laser equipment is also a certain requirement, because fiber laser marking machine is not a printer, said popular point, fiber laser marking machine marking pattern is based on the resolution of the pattern to mark the color of the picture The color of the place is darker and the color of the picture is lighter. Fiber laser marking machines can not make adjustments according to the color of the pattern to produce the corresponding color.

The colors that are marked on the objects are different based on the colors of the objects themselves. Some materials can be produced in many colors, such as stainless steel, and even colorful. However, no matter which color is marked, it is necessary to adjust the parameters in advance. After the adjustment, the parameters will remain unchanged during the marking process. Therefore, if our pictures are rich in color, but the contrast between colors is not high, they will be lost after marking with a fiber laser marking machine. The details, many places where the contrast is not high may come out after a color, they are stuck together. It is best to use very high contrast images. The image reproduction is relatively high.

Patterns identified on the laser marker software. It's best to use COREDRAW (this can eliminate many unnecessary details). And then even if the picture is fine, it's not easy to make a significant contrast. Fiber laser marking machine marking pattern is preferably a simple, relatively uniform depth map.
