[0002] At present, the existing alkaline battery production process includes positive electrode ring forming-the first positive electrode ring is inverted into the steel cylinder-the second ring is inserted into the cylinder-the third ring is inserted into the cylinder-automatic detection-crimping-coating sealant - human diaphragm tube - adding electrolyte - absorbing electrolyte - adding zinc paste - inserting negative electrode collector - crimping - automatic detection - storage - detection voltage, current - finished product packaging - storage, in the whole production process, usually by conveying Belts or other conveying methods connect the independent process machines in series. The conveying devices mostly use separate power motors. The entire production line has a large number of equipment, occupies a large area, and consumes high energy. It is difficult to achieve synchronous work

[0003] Especially in the battery production process, between the battery ring-in process and the sealing agent application process, it usually needs to go through multiple conveying channels for transmission and screening, S-curve sorting, and carbon ring number detection. Moreover, the existing ring-in equipment is not It uses three carbon rings to push them into the battery steel case one by one in an orderly manner. Its work efficiency is low, and it is easy to have few or missing rings, which affects the product qualification rate; in addition, traditional battery sealing agent coating equipment usually passes The cylinder drives the nozzle to move back and forth to complete one push and one spray, and cooperate with the rotation of the battery steel shell to realize spraying sealant on the battery steel shell. The friction between the pressure roller and the surface of the battery steel case drives the steel case to rotate around its axis. On the one hand, during the driving process, the pressing force of the pressure roller on the steel case can easily cause the shape of the steel case to deform, which in turn affects the next process and Battery quality; on the other hand, when the sealing agent is sprayed on the steel shell of the battery through the nozzle, a relatively concentrated point is formed at first, and the surface of the steel shell is evenly coated by the rotation of the steel shell and the fluidity of the sealing agent. With sealing agent, it is difficult to achieve uniform coating of the sealing agent, and after the coating is completed, some sealing agent will remain in the nozzle, and when the cylinder drives the nozzle to reset, the sealing agent will often drip, resulting in waste of resources and increased costs.
