By the vertical difference between the two records by the displacement sensor 420, the degree of collapse of the gear sensor during the welding process can be detected, thereby judging the welding quality.
[0023] In this embodiment, the laser welding machine 200 is used to generate a laser beam to achieve the function of laser welding. For example...

The relative movement of the lower pressing plate 410 and the workbench 300 is driven by the driving piece 430, until the light-transmitting part 411 of the lower pressing plate 410 is pressed on the upper shell.
