[0033] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0034] like Figure 1 As shown, the embodiment of the utility model provides a stamping and coding line, which includes a conveying device 2, a multi-joint mechanical arm 3, a laser generator 1 and a coding auxiliary device 4. Among them, the conveying device 2 includes a base 21 and a shuttle mechanism 22, the shuttle mechanism 22 is arranged on the base 21, and is used to carry the workpiece 100, and the shuttle mechanism 22 can drive the workpiece 100 to move on the base 21, so that the workpiece 100 moves to the position of the laser generator 1. The coding auxiliary device 4 is arranged on the laser generator 1, and the laser generator 1 is arranged at the output end of the multi-joint robot arm 3. The coding auxiliary device 4 is used to simulate the set coding angle and the set coding focal length between the laser lens of the laser generator 1 and the coding surface of the workpiece 100. After the workpiece 100 reaches the position of the laser generator 1, the multi-joint robot arm 3 only needs to drive the laser generator 1 to move, and drive the coding auxiliary device 4 to move and abut the coding surface of the workpiece 100. At this time, the actual coding angle and the actual coding focal length between the laser lens of the laser generator 1 and the coding surface are the set coding angle and the set coding focal length, and no on-site debugging is required.

[0035] The stamping and coding line can effectively simulate the angle and focal length of the laser lens optical path of the laser generator 1 through the coding auxiliary device 4, thereby greatly simplifying the on-site debugging process of the laser generator 1, and avoiding the problem of low debugging efficiency caused by low on-site manual measurement accuracy, which can greatly improve the production efficiency of the stamping and coding line.
