Lithium battery rolling automatic centering and deviation correcting device

Abstract

The invention discloses a lithium battery rolling automatic centering and deviation correcting device. The device comprises a base platform, as well as a first pressing roller, a second pressing roller, a third pressing roller, a material receiving roller, an analog to digital (A / D) conversion module, a programmable controller and a stepping motor, which are arranged on the base platform, wherein the first pressing roller, the second pressing roller, the third pressing roller and the material receiving roller are sequentially arranged from left to right and movably connected with the base platform; a photoelectric sensor which is connected with the A / D conversion module is arranged on the first pressing roller and connected with the stepping motor through the programmable controller; and a ball screw transmission mechanism is arranged between the stepping motor and the material receiving roller. By using the lithium battery rolling automatic centering and deviation correcting device, the deviation of pole pieces in a rolling process can be corrected, the consistency of pole piece lamination is ensured, the smoothness of subsequent processing is ensured, production efficiency is indirectly improved, and the labor intensity of an operator is reduced. The lithium battery rolling automatic centering and deviation correcting device has the characteristics of simple structure, convenience in use and the like, and is suitable for popularization.

Description

technical field [0001] The invention relates to a lithium battery rolling automatic edge correction device. Background technique [0002] With the continuous miniaturization or high performance of portable machines such as mobile phones, notebook personal computers, and portable lithium battery rolling automatic edge correction device V machines, it is required that the battery used as its power source be miniaturized and high-energy. Currently, lithium batteries are increasingly used as batteries that can meet such requirements. In addition, with the electronic control of cameras, the practical battery that has been used as a power source has been increasingly turned to lithium batteries.

[0003] After coating the pole piece, it is necessary to carry out rolling treatment on the pole piece. Through rolling treatment, the coating is thinned and compacted to the required compaction density. The sheets will be offset, resulting in uneven stacking of the pole sheets on the receiving roller, and even the inability to carry out subsequent production, which greatly reduces the production efficiency. In addition, the traditional manual correction of the edge is not only labor-intensive and slow in response, but also in manual alignment. It is easy to cause personal injury during the process
