[0027] With the above solution, by providing the rotating assembly 4 , when the staff needs to clamp the lithium battery panel 3 , the rotating assembly 4 is used to facilitate the staff to operate it.

[0028] refer to Figure 2 、 Figure 3 and Figure 4 The clamping assembly 5 includes a clamping groove 51, a clamping block 52 and a soft pad 53. There are several clamping grooves 51, clamping blocks 52 and soft pads 53. Several clamping grooves 51 are opened at the top of the processing plate 2 and extend to the inside of the processing plate 2. The surfaces of several clamping blocks 52 are slidably connected to the surfaces of the clamping grooves 51, and the opposite sides of several soft pads 53 are fixedly installed to the side opposite to the clamping block 52.

[0029] With the above solution, by providing the clamping assembly 5 , when the staff is coating the lithium battery plate 3 , they can first clamp the lithium battery plate 3 to facilitate subsequent coating.

[0030] refer to Figure 2 Two limiting rings 6 are fixedly installed on the surface of the rotating rod 41 , and the two limiting rings 6 are used to ensure the normal rotation of the rotating rod 41 .

[0031] With the above solution, by providing the limiting ring 6 , the rotating rod 41 can be restricted by the limiting ring 6 during rotation, thereby ensuring that the rotating rod 41 does not move during the rotation process.
