Description

【Technical field】 [0001] The invention relates to battery manufacturing equipment, in particular to a cam type cylindrical battery sealing machine. 【Background technique】 [0002] In the production of cylindrical batteries, sealing is a very important part. In the prior art, most of the equipment for sealing batteries adopts gas-hydraulic pressurized cylinder sealing machines or punch-type sealing machines. [0003] The air-liquid pressurized cylinder sealing machine adopts the air-liquid pressurized cylinder and pneumatic mechanism to seal the movable positioning column battery on the base. The degree of automation is not high, and the air consumption of the air-liquid pressurized cylinder is large. If the speed increases The air consumption has increased significantly, which requires high infrastructure; at the same time, it is not easy to control the size of the air pressure and the stroke of the pressurization by using the air-hydraulic booster cylinder, and it is not ea...

[0003] The air-liquid pressurized cylinder sealing machine adopts the air-liquid pressurized cylinder and pneumatic mechanism to seal the movable positioning column battery on the base. The degree of automation is not high, and the air consumption of the air-liquid pressurized cylinder is large. If the speed increases The gas consumption has increased significantly, which requires high infrastructure; at the same time, it is not easy to control the size of the air pressure and the stroke of the booster with the gas-hydraulic booster cylinder, and it is not easy to control the pressure and speed of the punch when sealing.

[0004] Punch-type sealing machine adopts two-petal locking tile, the positioning is not accurate, the sealing is bent and deformed too quickly, it is easy to punch the battery, the sealing is easy to produce burrs, the sealing quality is unstable, and it cannot provide a high-level shaping device. It is difficult to demold the battery, and the efficiency is relatively low Low
