Description

Technical Field

[0001] The present invention relates to the field of lithium battery devices, and in particular to a lithium battery pole piece drying device. Background Art

[0002] During the manufacturing process of lithium-ion batteries, it is necessary to remove moisture from the battery. Therefore, the inorganic lithium salt in the electrolyte of lithium-ion batteries will produce a chemical reaction when it comes into contact with water, which seriously affects the comprehensive performance of the battery. During the manufacturing process of lithium-ion batteries, it is usually necessary to dry the pole pieces, pole piece cores or semi-finished batteries. Patent application number: CN202120775441.4 discloses a lithium battery processing pole piece drying device, including a base, a support rod, a motor and a sleeve. Four brackets are fixed on the outside of the sleeve. The staff places the lithium battery pole piece on the top of the bracket. The two clamps clamp the pole piece under the action of the spring. After the pole pieces are fixed on the top of the four brackets, the drive motor runs, the motor drives the gear to rotate, the gear drives the sleeve to rotate through the gear ring, the sleeve drives the four brackets to rotate ninety degrees, and the bracket drives the pole piece to rotate inside the concave frame. However, this type of drying device can only dry one pole piece at a time, and the drying efficiency is low.

After the slide plate reaches the support rod position on the other side of the drying box, the arc-shaped part on the support rod is inserted into the lifting ring to lift the lifting ring, so that the threaded block and the screw rod are separated, and the next slide plate continues to move to the support rod position to push the previous slide plate to move, so that each slide plate can be stacked on the support rod position. When the slide plates are stacked, the corresponding slide block is driven to move again by the feeding motor, and the screw rod is driven to rotate in the opposite direction by the drying motor, and the threaded block is stuck on the screw rod again, so that the electrode piece passes between the two air outlet plates again to achieve drying of the electrode piece. The device can adjust the distance between adjacent electrode pieces, and pass the electrode pieces between the two air outlet plates in turn, so as to achieve rapid drying of the electrode pieces, and multiple electrode pieces can be dried at one time, which greatly improves the drying efficiency of the electrode pieces.
