[0002] At present, alkaline water hydrogen production is the most widely used and most mature method of green hydrogen production. Its core component is the alkaline water electrolyzer, which is composed of multiple electrolysis chambers. Each electrolysis chamber is assembled from plates, gaskets, diaphragms and support nets. The chambers are then tightened by screws to obtain the alkaline water electrolyzer. With the introduction of the national green hydrogen policy, the industry aims to assemble large-scale tanks with a hydrogen production capacity of hundreds or even thousands of cubic meters per hour, in order to reduce "wind and solar power abandonment", promote industrial development, and balance supply and demand.

[0003] Alkaline electrolyzer hydrogen production equipment is mainly assembled from hundreds of plates, and the plates have both front and back sides. The plates involve multiple flipping and repositioning operations during machining, electroplating, inspection and assembly, and most of these operations are done manually by workers. At present, after electroplating, the electrolytic cell plates are hoisted to the ground in a vertical state, supported manually, and lifted and flipped 90° to lay flat on the pallet. Then the inspectors inspect one side, and after the inspection, they manually flip 180° to inspect the other side. On the one hand, it consumes manpower and time, and on the other hand, a plate is heavy, and improper operation can easily cause injuries to workers or damage to the plates.
