Embodiment approach

[0043] As an embodiment of the present invention, a cleaning mechanism 21 is provided in the middle of the feeding conveyor belt 2, and the cleaning mechanism 21 includes a cleaning bracket 211, a cleaning motor 212, a two-way screw rod 213, a moving block 214 and a guide rod 215. The cleaning bracket 211 is fixed on the base 1, and the upper end of the cleaning bracket 211 is rotated to install a two-way screw rod 213, and the rotation of the two-way screw rod 213 is controlled by the cleaning motor 212, and the outer ring of the two-way screw rod 213 is connected to two moving blocks 214, the two-way screw rod 213 is used to drive the two moving blocks 214 to be close or apart; On the upright column, a brush plate is provided at the bottom of the moving block 214, and the brush plate is used to brush off the dust on the surface of the lithium battery pole plate. When the cleaning motor 212 drives the two-way screw rod 213, the two moving blocks 214 drive the brush plate to c...

Abstract

The invention belongs to the technical field of lithium battery production, in particular to a lithium battery production process. A packer is adopted in the process. The packer comprises a base, a feeding conveyor belt, a film feeding device and a film coating device, wherein the film feeding device is arranged in the middle of the base; the feeding conveyor belt arranged on the base is arrangedon one side of the film feeding device; the feeding conveyor belt rotates under the control of a driving motor; the film coating device arranged on the base is arranged on the other side of the film feeding device; the surface of the feeding conveyor belt is provided with trapezoidal teeth; and through use of the toothed conveyor belt, the function of conveying lithium battery plates can be realized, and meanwhile the lithium battery plates can be protected from being damaged. A lifting mechanism drives a lower slide block to slide on the base, and the lower slide block drives a first supporting plate to rotate so as to change the height of the first supporting plate in the vertical direction. The spacing between a first conveyor belt and a second conveyor belt varies along with the operation of an oil cylinder, so that lithium battery plates of different thicknesses can be coated with the lifting mechanism.

Description

technical field [0001] The invention belongs to the technical field of lithium battery production, in particular to a lithium battery production process. Background technique [0002] In the production process of lithium batteries, a separator needs to be arranged between the plates, and the separator is in the form of an insulating film. The transmission device of the existing packaging machine adopts a rigid mechanism, which will scratch the surface of the lithium battery plate when the lithium battery plate is transported, and the lithium battery plate is not removed before the coating, resulting in thin film The quality is not up to par. If the dust cannot be completely removed, it will be brought into the interior of the battery pole core, which will pierce the separator and cause a short circuit of the battery. Therefore, whether the dust can be completely removed is a key factor in determining the quality of the battery. [0003] There are also some technical soluti...
