[0002] In the production and manufacturing field of mechanical parts, the information mark on the surface of component, such as the number and model of valve plate, is an important link of quality control, tracking and tracing and product management. With the progress of science and technology, laser coding technology has been widely used due to its high precision, non-contact processing, permanent marking and wear resistance.

[0003] However, in the production line of compressor valve plate and cover sheet, there are many types of workpieces with different shapes. These sheet-shaped workpieces may be dozens of types, and the demand for each type is very large. The traditional laser coding operation mode usually relies on a system composed of a workbench equipped with a simple limiting device and a laser coding machine.
