[0030] The method of use and advantages of this utility model: The working process of this lithium sheet cutting device is as follows:

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the lithium sheet to be cut is placed between two clamping posts 502. The clamping motor 202 is started to drive the bidirectional screw 203 to rotate, bringing the two guide blocks 301 and the connecting plate 302 closer together. This, in turn, brings the two support posts 501 and the clamping posts 502 closer together to clamp the lithium sheet. When the cutting position of the lithium sheet needs to be adjusted, the rotary motor 507 drives the upper support post 501 and clamping post 502 to rotate. The transmission belt 503 and transmission rod 504 cause the lower support post 501 and clamping post 502 to rotate accordingly, thereby rotating the clamped lithium sheet.

During clamping, the connecting plate 302 drives the two sets of protective plates 402 to move closer together through the connecting rod 401, so that the two sets of protective plates 402 fit together. During the cutting process, the protective plates 402 prevent the cutting debris from flying and causing injury to the workers, improving the safety of the operation. At the same time, the flying debris is intercepted and falls into the collection box 103 below for collection, which facilitates subsequent cleaning work.
