What is the difference between domestic and imported PCB laser cutting machine?

my country's high-tech level has always been relatively backward compared with European countries. In the PCB fiber laser cutting industry, China's high-tech laser equipment started late, and key components rely on imports. The laser generator for PCB fiber laser cutting The components, especially the high-power ultraviolet laser generators, are sourced from capitalist countries such as the United Kingdom, and rely on imports for a long time. Imported products are known for their quality, and their prices are usually twice as high as domestic machinery and equipment, and expensive machinery and equipment maintenance fees are also deducted. So where is the key to this difference?

PCB fiber laser cutting is divided into four major control modules: optical system, mechanical structure, mobile phone software automatic control system, and auxiliary system software.

Optical system

The optical system includes laser generator, scanning galvanometer, field lens, beam expander lens, adjustment frame, laser spectacle lens, etc.

The outdated optical system is a key copy of domestic PCB fiber laser cutting and imported PCB fiber laser cutting. Because of the shortage of technical aspects, the price of imported products is more expensive. Domestic machinery and equipment cannot raise the technical requirements, especially It was in the initial stage that such machines and equipment were in the ban on overseas, and it was difficult to buy high-power ultraviolet laser generators. Until now, it is difficult to buy ultraviolet laser generators above 60W in the Chinese sales market. Although the domestic high-power ultraviolet laser generators are gradually manufactured in China at this stage, the key components are imported control modules at this stage. It is worth mentioning that the crystalline system in the electronic devices of the British laser generators There has always been a technical shortage in making technology, and it was not until the first two years that crystal making technology gradually became available. At this level, domestic crystal has always been at the leading level.

The key to the technical shortage of the optical system comes from the technology of the key control module of the laser generator. The precision, speed, and technology of the automatic control system of the high-speed scanning galvanometer cannot guarantee the overseas level. The field lens, especially the telecentric The field lens is not manufactured in France, and the key is reflected in the coating technology of the surface and the shortage of basic spectacle lens processing technology.

Mechanical structure

Mainly the application of servo motor and its Z-axis motor. In contrast, everyone in this industry understands that the overall PCB fiber laser cutting precision is caused by various factors, and the precision of the motor is very important. Although the domestic motor is widely used, the components of the domestic motor are all available. Imported by itself.

Mobile phone software automatic control system

The domestic production process of mobile phone software control system is fast. In comparison, the shortcomings in the mobile phone software industry are not so obvious. The shortcomings of domestic PCB fiber laser cutting mobile phone software depend on the shortage of excellent talents in the automatic control system. The advantages of imported PCB fiber laser cutting mobile phone software manipulation depend on the structured design plan, more in line with personalized regulations, fewer mobile phone software bugs, and mobile phones. The level of software integration is strong. Generally, some system software manipulation port numbers of imported products are not open to customers. If you need to open to the outside world, you must deduct additional expenses. The advantages of domestic PCB fiber laser cutting depend on the ability to change on the spot according to customer requirements and open ports anytime and anywhere, which also leads to insufficient reliability of the program process, lack of reliability and the ability to control macroeconomics.

Auxiliary system software

The precision of the auxiliary system software is equally critical. For example, marble slabs and sound card racks. The overall flatness and flatness endanger the precision. Usually PCB Laser cutting machine manufacturers have to consume a lot of time to adjust the flatness of machinery and equipment at the manufacturer or even on the spot according to special tools. In these respects, domestically produced goods lack the spirit of craftsmanship, so they can be made at the right price, and done according to their own specifications, and they are not allowed to be returned or exchanged to customers on the spot.

Summary: The difference between domestic PCB fiber laser cutting and imported products depends on the ability to control quality. Imported products are also integrated assembly. Why is the high precision and stability of other people's assembly? On the one hand, it depends on the level of special tools and equipment of domestically produced machinery and equipment, on the other hand, it depends on the lack of a craftsmanship and the lack of quality control and management methods for processing plants. In the same way, some manufacturers have more fake and inferior products due to price competition. This is also a marketing strategy, and there are classic cases like that. The objective fact depends on the competitiveness of relatively imported products and their key technologies have never been improved. ,Thought-provoking.
