Electrode plate roller type positioning press-fitting device

Abstract

The invention belongs to the technical field of electrode slice production, and particularly relates to an electrode slice roller type positioning press-fitting device which comprises a base, two side plates are symmetrically and fixedly connected to the upper end of the base, and the opposite sides of the two side plates are rotationally connected with an upper pressing roller through a first rotating shaft; the opposite sides of the two side plates are rotationally connected with a lower pressing roller located on the lower side of the upper pressing roller through a second rotating shaft, the upper end of the base is further fixedly connected with a lifting adjusting mechanism used for driving the lower pressing roller to move up and down, the outer side of the left side plate is fixedly connected with a supporting plate, and the upper end of the supporting plate is fixedly connected with a rotating motor. The output end of the rotating motor is fixedly connected with one end of a first rotating shaft, and the other end of the first rotating shaft is fixedly connected with a driving chain wheel. Synchronous rotating driving of the upper pressing roller and the lower pressing roller can be achieved only through one rotating motor, the distance between the upper pressing roller and the lower pressing roller can be adjusted, dust attached to the surface of the upper pressing roller can be rapidly cleaned in real time, and the production quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electrode sheet production, in particular to an electrode sheet roller-type positioning and pressing device. Background technique [0002] In the process of lithium battery production and processing, it is necessary to prepare positive electrode sheets and negative electrode sheets first. The specific process is: carry out the corresponding positive and negative electrode ingredients, and then coat the positive electrode ingredients and negative electrode ingredients on the corresponding metal on the electrode coating machine. A positive electrode sheet and a negative electrode sheet are prepared on the foil. The electrode sheet prepared after coating needs to be further compacted on a rolling device in order to improve the energy density of the battery. [0003] The current electrode sheet has the following problems in the production rolling: [0004] 1. Due to the problem of dust falling on the surfac...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the problem of dust falling on the surface of the upper pressing roller, more dust and impurities will adhere to the surface, which affects the quality of the electrode sheet in the actual rolling production;

[0005] 2. In order to meet the rolling requirements of different thicknesses, the upper pressing roller and the lower pressing roller can be adjusted and moved relative to each other, but this causes the rotation drive mechanism of the upper pressing roller and the lower pressing roller to not be well structured together, and often requires The two sets of driving mechanisms drive the upper and lower pressure rollers to rotate separately, which can not cause high cost of use, and the transmission speed between the upper and lower pressure rollers is difficult to keep consistent, which affects the use of roller pressure.
