[0039] Working principle: the lithium battery modules are placed on the lifting plate 304 in sequence, and the cylinder 1 302 is started to drive the lifting plate 304 to gradually approach the conveyor belt. When the inclined plate 401 is blocked by the base 1, the elastic member 404 contracts, and the moving block 403 slides inside the guide groove 402, and the slider 405 slides on the slide rail 406, so that the inclined plate 401 is squeezed and is in a downward tilted state.

After grabbing, the hydraulic cylinder 311 drives the moving seat 312 to slide inside the slide groove 313 until the unloading robot arm 315 is at the edge of the unloading tray 319. The unloading robot arm 315 releases the lithium battery module, and the unloading tray 319 receives the lithium battery module. After receiving the module, the motor 2 317 drives the transmission belt 318 to drive the unloading tray 319 to rotate a quarter of a circle through the rotating shaft, so that the lithium battery module just placed is not on the same horizontal line with the unloading robot arm 315, and then repeats the above steps. The unloading tray 319 receives multiple groups of lithium battery modules for placement. After placement, the motor 1 308 starts to drive the support frame 309 to rotate. After changing the direction of the support frame 309, it is convenient for the unloading robot arm 315 to grab the lithium battery module to the unloading area. Single loading ensures a detailed inspection of each module, while batch unloading improves the overall production speed and achieves dual guarantees of efficiency and quality.
