[0032] Specifically: the first cylinder 304 is activated to push the first moving block 314, which in turn drives the moving rod 312 to move. At the same time, the moving plate 313 stretches the reset spring 311 inside the reset groove 310, and then drives the second moving block 315 to move, so that the locking block 316 moves away from the interior of the placement block 306, and the placement block 306 is released from the locked state.

[0033] In one embodiment, the top of the workbench 101 is fixedly connected to the bottom of the connecting frame 401, the top of the connecting frame 401 is fixedly connected to the top of the housing of the second drive motor 402, the output end of the second drive motor 402 is fixedly connected to the bottom end of the first pulley 403 via a coupling, one side of the connecting frame 401 is fixedly connected to one side of the support frame 404, the inner wall of the support frame 404 is rotatably connected to the top outer wall of the second pulley 405, the outer walls of both the second pulley 405 and the first pulley 403 are movably connected to the inner wall of the connecting belt 406, and the top end of the second pulley 405 is fixedly connected to the bottom end of the housing of the finger cylinder 407.

[0034] Specifically: The second drive motor 402 is started to drive the first pulley 403 to rotate, which in turn drives the second pulley 405 to rotate through the connecting belt 406. The rotation of the second pulley 405 drives the placement groove 307 to rotate, thereby causing the placement block 306 to rotate 180 degrees, which in turn drives the workpiece to rotate.

[0035] Working principle: The workpiece is placed inside the placement block 306. The first drive motor 301 is started to drive the rotating plate 302 to rotate. The rotation of the first drive motor 301 moves the workpiece to a position below the central rotating shaft 204. The pressing cylinder 202 is started to move the pressing plate 203 downward, which in turn drives the central rotating shaft 204 to press the top of the workpiece. Then, the workpiece is placed inside another set of placement blocks 306, and the workpiece is welded by the laser welding gun 103. The first cylinder 304 is started to push the first moving block 314, which in turn moves the moving rod 312. At the same time, the moving plate 313 stretches the reset spring 311 inside the reset groove 310, which then moves the second moving block 315.

Then, the laser welding gun 103 is used to weld the other side. As the workpiece rotates, the central rotating shaft 204 rotates accordingly. After one set of workpieces is welded, the first drive motor 301 is activated to drive the rotating plate 302 to rotate, thereby welding another set of workpieces.
