The side surfaces of the two support rods 241 arranged in parallel and close to the suspension arm 21 are respectively connected with a transverse roller 211 in a rolling way.

Therefore, in the process that the crane 23 drives the suspension arm 21, the grab hook 22 and other structures to move up and down, the suspension arm 21 can be ensured to move along the Z direction all the time through the matching between the roller and the slide rail 24, and the deviation is prevented; on the other hand, the surface contact can be converted into rolling contact through the rolling of the roller, and the suspension arm 21 is ensured to be stable and smooth in the moving process. The slide rails 24 and the rollers are arranged to play a role in guiding and smoothing. The matching of the sliding block 242, the longitudinal roller 212 and the two support rods 241 can improve the stability and prevent the suspension arm 21 from shaking.

Generally, a positioning sensor connected to the PLC system is disposed at the positioning hole 301 of the cathode plate 300, and after the positioning sensor senses the first hook 221 and the second hook 222, the positioning sensor feeds back position information of the first hook 221 and the second hook 222 to the PLC system, and at this time, the PLC system controls the relay to enable the tail end of the first hook 221 and the tail end of the second hook 222 to approach each other, and in this process, the first hook 221 passes through the positioning hole 301 at the top end of the cathode plate 300. The grapple 22 is sucked so that the cathode plate 300 is firmly grasped in the grapple 22. Then, the PLC system operates the crane 23 to drive the boom 21 to move upwards, so that the cathode plate 300 grabbed by the grabbing hook 22 can be lifted upwards from the electrolytic bath until the inside of the traverse cart 200.
