Traceability processing of PCB two-dimensional code laser marking machine

The two-dimensional code has a wide range of information transmission and large capacity of information transmission, and has been widely used, and it has almost completely replaced the original bar code. From the Internet to the life field, a new wave of two-dimensional code marking is now set off in the industrial field. The characteristic of the QR code in the circuit board industry is that it can be retained in a poor-quality environment and can still be clearly readable. Therefore, the PCB two-dimensional code laser marking machine also came out.

On the other hand, the precision requirements in the industrial field are getting higher and higher, especially the size of PCB industrial parts is getting smaller and smaller, leaving very little space for marking the two-dimensional code, usually the area that needs to be marked is below 3x3mm. The only thing that can meet this requirement is laser marking technology. This type of commonly used industries such as mobile phones, wearable electronics, smart homes, computers, precision industrial parts, etc.

A mature product is combined by purchasing parts from different manufacturers. The final manufacturer will require upstream enterprise suppliers to mark the two-dimensional code on the part. On the one hand, the source of the product can be checked by scanning the two-dimensional code. Tracking, on the other hand, recognizes and reads through the camera on the factory assembly line, eliminating the need for manual entry, and can track the flow of products, production progress, etc. And in the later stage, if there is a problem with the product, through troubleshooting, a certain part of the problem can be checked, and the manufacturer can be traced and corrected in time. In a complete set of PCB factory product traceability system, traceability system, camera recognition, and QR code processing are the key points. In order to cooperate with the factory assembly line production, a laser marking machine is integrated to realize QR code automatic marking, automatic loading and unloading, Automatic reading, automatic rating, and automatic upload of data have become key technologies, and the later traceability is handed over to another system of the factory to interface with the office system, and the data uploaded from the laser marking machine will be obtained.

In the future factories, there will be intelligent production. The circuit board industry has a high degree of integration. The PCBQR code is an indispensable key link as an important information carrier, and the marking of the QR code depends on laser marking Machine technology.
