Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, and particularly relates to a battery pole column cap removing mechanism. Background Art

[0002] In order to improve the volume specific energy of the battery, the current practice is to increase the utilization rate inside the battery case. The bus bars in each single cell of the battery adopt a direct connection structure, and at the same time, the bus bars are immersed in a glue tank for sealing. Moreover, the connecting external pole columns directly extend out from the bus bars. During the assembly process, the pole columns need to be sealed with glue at the same time, and the middle cover on the pole column is covered with a cap. After the glue dries, the cap on the pole column needs to be unscrewed. In the prior art, the method for removing the battery pole column cap is usually manual operation with a special tool held by hand to remove the cap. This method not only results in low efficiency of cap removal, but also increases the labor intensity of workers, which is not conducive to the improvement of battery production efficiency. Therefore, it is urgent to study a battery pole column cap removing mechanism to solve the above problems. Content of the Utility Model

[0007] As a preferred technical solution of the present utility model, the lifting assembly includes a pair of second cylinders vertically fixed on the upper surface of the bearing strip and a lifting frame horizontally arranged below the bearing strip; the lifting frame has a "cross" structure; the output ends of the two second cylinders both slide through the bearing strip and are respectively connected to a pair of opposite ends of the lifting frame.

[0008] As a preferred technical solution of the present utility model, the rotation driving assembly includes a servo motor vertically fixed in the middle of the lifting frame; the output shaft of the servo motor passes through the lifting frame with a gap and is coaxially fixed with a transmission shaft; a rotating block is fixed at the lower end of the transmission shaft; receiving grooves are formed on four side surfaces of the rotating block, and each receiving groove penetrates through the upper and lower surfaces of the rotating block; the upper ends of the four clamping rods are respectively rotatably connected in the four receiving grooves.

[0010] The present utility model has the following beneficial effects:

[0011] In the present utility model, the storage battery is placed on the workbench, and the pole cap of the storage battery is located directly below the rotation driving assembly. The lifting assembly drives the clamping rod to move downward through the rotation driving assembly, and then the pushing and pulling assembly drives the lower ends of the four clamping rods to approach each other, so that the pole cap of the storage battery is clamped by the four clamping rods and the four convex blades cut into the root of the pole cap. Then, while the lifting assembly drives the clamping rod to move upward, the rotation driving assembly drives the clamping rod to rotate, so as to realize unscrewing the pole cap from the storage battery and the convex blades completing the circumferential cutting of the root of the pole cap.
