Problems solved by technology

[0002] Traditional product coding is mainly inkjet, but it often needs to be in contact with the product and is easy to erase, and the consumables are large, costly, and unfriendly to the environment, while laser coding technology has non-contact non-destructive marking and is environmentally friendly. The advantages of friendliness, high processing accuracy, long-lasting marking, long service life and fast processing efficiency gradually occupy the field of coding
[0003] However, when laser marking machines are used in industrial production at this stage, most operators still need to manually position the items to be marked and manually adjust the focus with experience. The location can only be removed after the coding is completed. This traditional laser marking method not only inevitably affects the marking accuracy, but also difficult to meet the needs of a large number of workpieces for one-time marking. The efficiency is low, and the labor cost is high, and the loading and unloading labor is large. , low security
[0004] In addition, even for laser marking systems that have applied automation technology, the method of using fixed fixtures to position workpieces is not only costly, but also not conducive to the simultaneous positioning of multiple workpieces, and will also cause instability of human positioning errors
