An automatic lithium battery cell tablet pressing device and tablet pressing method thereof

Abstract

The invention discloses an automatic lithium battery cell tablet pressing device and a tablet pressing method thereof, which mainly solve the problems in the prior art that the lithium battery cell tablet pressing requires manual operation, labor intensity is high, and tablet pressing efficiency is low; During the tablet pressing process, the piston often drifts or moves accidentally, resulting in inaccurate positioning and damage to the equipment, and the relative axial clearance of the driving device in each shaft, which makes it difficult to achieve precise positioning when the driving device rotates. question. The automatic lithium battery cell tablet pressing device includes: a box body with a pressing plate inside, a driving device located below the box body, and a motor inside the driving device; a hydraulic cylinder with a pressing plate at the lower end. The invention can overcome the problems existing in the prior art, improve the automation degree of the equipment, and both the piston and the driving device can realize precise positioning, and has good popularization and utilization value.

Description

technical field [0001] The invention relates to the technical field of lithium battery manufacturing, in particular to an automatic lithium battery cell tablet pressing device and a tablet pressing method thereof. Background technique [0002] With the development of microelectronics technology at the end of the 21st century, miniaturized equipment is increasing day by day, which puts forward high requirements for power supply. Lithium batteries have entered a large-scale practical stage. A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. It is different from a rechargeable battery. Lithium-ion batteries are different from lithium-ion polymer batteries. During the production and processing of lithium batteries, lithium batteries need to be pressed into sheets. [0003] In the prior art, there are many shortcomings in the pressing of lithium battery cells, which hind...

AI Technical Summary

Problems solved by technology

[0008] One of the purposes of the present invention is to provide an automatic lithium battery cell tableting device to solve the problem of the weight of the piston in the hydraulic cylinder in the prior art, or the sealing problem of other parts connected to the piston, or the hydraulic cylinder System leakage, damage to the inner surface of the cylinder shell, vibration or contamination problems, and other technical problems such as alignment and assembly, resulting in unexpected drift or movement of the piston, resulting in inaccurate positioning of the piston itself, which in turn damages the equipment

[0009] The second object of the present invention is to provide an automatic lithium battery cell tableting device to solve the problem in the prior art that manual intervention is required during the lithium battery cell tableting process, which not only reduces the tableting efficiency, but also increases the labor intensity. big problem

[0010] The third object of the present invention is to provide an automatic lithium battery cell tableting device to solve the problem that the driving device in the prior art often suffers from wear and tear due to the manufacturing tolerance of each component and the axial bearing area of ​​the shaft. The relative axial play is generated in each shaft, which makes it difficult to achieve precise positioning when the drive device rotates to the specified position
