[0057] The working principle of the automatic counting and stacking device for pre-treated plates proposed in the embodiment of the present application is as follows: the first conveying roller 110 receives the plates from the pre-treatment line 00.

[0058] The flip arm 220 is in a state where the axial direction of the supporting roller 231 is in a horizontal direction. After the sheet material arrives at the supporting roller 231 from the first conveying roller 110, the supporting roller 231 rotates and is conveyed forward under the power of the first conveying roller 110. When flipping, the flip arm 220 flips downward 90 degrees, so that the sheet material is free from the restriction of the supporting roller 231 and falls onto the second conveying roller 310.

[0059] The two transmission mechanisms 323 are driven by the lifting motor 322, and the transmission mechanism 323 drives the second transmission shaft 324 to rotate.
