Metal engraving codes are also known as laser engraving codes, laser etching codes, laser jet codes, dot matrix codes, etc. It is a way of marking the barcode on the product by laser engraving. Generally, the DPM (Direct Part Mark) code is used, and the Datamatrix code (DM code) is the most commonly used one. The DM code is a It has the characteristics of high density, small size and large amount of information. It is widely used in the anti-counterfeiting of commodities, small parts identification, circuit board parts, IC anti-counterfeiting, various metal products identification, overall identification and so on.

Therefore, there are usually some kinds of metal codes, one is DPM code, the other is DM code, and in terms of technology, there are etching codes, laser engraving codes, dot matrix codes, inkjet codes, etc. In the production process of battery cells, the above code system is often used for product traceability and process control. The XT6201 produced by Xingtong IOT can scan all kinds of laser engraving codes very well.

XT6201 adopts 1280*960CMOS, which can perceive all kinds of metal codes very well. In terms of algorithms, Xingtong has specially developed industrial decoding algorithms for various industrial applications, and has good decoding performance for laser engraving, dots and other code systems. At the scanning distance, it can detect the change of 40CM objects, and can decode and read within 100ms. It adopts a soft-encapsulated design in appearance, which can better resist shock and fall, and has been used for many large domestic lithium batteries, industrial Used by battery companies.
