Referring to fig. 2 and 13, in one embodiment, to further improve the marking performance of the laser marking machine. The size detection device 800 is used for measuring the size of a product and is arranged between the feeding mechanism 430 and the marking mechanism; the size detection apparatus 800 includes a third X-axis module 810, a third Y-axis module, a third mounting bracket 830, a camera 840, and a light source 850; a third X-axis module 810 is mounted on the workstation 110, the third Y-axis module 820 is mounted on the third X-axis module 810, the third mounting bracket 830 is mounted on the third Y-axis module 820, and the camera 840 and the light source 850 are mounted on the third mounting bracket 830.

It can be understood that the size detection device 800 is used for detecting the size of the product, and when the size detection device 800 detects that the product is an unqualified product, the product is transferred to the marking device 500 and the mark detection device 600, and is not operated until the product reaches the blanking device 700 and is conveyed to an unqualified product line by the blanking mechanism 710. Therefore, marking of products which are defective products at the beginning and mark detection after marking are reduced, workload of the marking device 500 and the mark detection device 600 is reduced, and marking efficiency of the laser marking machine is improved.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents made by the contents of the present specification and drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
