Description

A winding and collecting device for lithium-ion battery pole piece waste

technical field

The utility model relates to the technical field of lithium-ion batteries, in particular to a winding and collecting device for waste edges of pole pieces of lithium-ion batteries.

Background technique

The battery cell in a lithium-ion battery is composed of a positive electrode, a negative electrode sheet, and a separator. The positive and negative electrode sheets are made of aluminum foil/copper foil coated with positive/negative electrode materials. In order to increase the density and The consistency of the thickness, the positive and negative plates must be rolled after the coating process. However, a large amount of waste edges will be produced during roll pressing and slitting. At present, cartons are generally used to collect waste edges. Since the waste edges are thin and long in structure, and have a little strength and toughness, the waste edges of pole pieces will be stacked randomly. Putting it in a carton not only affects the appearance and cleanliness, but also takes up a lot of space, which is not conducive to transportation and storage.

Utility model content

The purpose of the utility model is to provide a simple and easy-to-operate lithium-ion battery pole piece waste edge winding collection device to realize the winding collection of the pole piece waste.

In order to achieve the above object, the utility model adopts the following technical solutions:

A winding and collecting device for lithium-ion battery pole piece waste, including a torque motor fixed on a fixed seat, the output shaft of the torque motor is connected to an air expansion shaft, and the horizontal movable sleeve on the air expansion shaft is The front baffle and the rear baffle, the expansion key of the air expansion shaft is located between the front baffle and the rear baffle.

In a further solution, the output shaft of the torque motor is connected to the air expansion shaft through a coupling.

In a further solution, a bearing seat is fixed on the fixed seat, and the end of the air expansion shaft passes through the bearing seat and is connected with the shaft coupling.

In a further solution, the torque motor includes a motor and a gear box.

Place the device directly under the roller slitting machine, and the operator adjusts the position of the rear baffle on the air shaft according to the width of the waste edge of the pole piece, then locks the rear baffle, and makes the air shaft go up by inflating The expansion key protrudes, and then connect the pole piece waste to be collected on the air shaft, turn on the torque motor, and the torque motor rotates to drive the air shaft to rotate, so that the pole piece waste is wound onto the air shaft. When the waste edge of the pole piece is wound in a large group, deflate the air expansion shaft, the expansion key on the air expansion shaft descends to its interior, separates from the waste edge of the pole piece, then removes the front baffle, and then winds the coil The good pole piece waste edge is taken off from the air expansion shaft and it is completed.

Therefore, the utility model can realize winding processing based on thin and long material strips such as copper foil and aluminum foil, and realize the winding and collection of waste edges and waste materials. By adjusting the distance between the front and rear baffles, certain The collection and treatment of thinner and long strips within the width range ensures the timeliness of waste treatment and reduces the space occupied by waste. And the on-site environment is guaranteed, and it is convenient for transportation. The device has good operability and economy.
