Improved soft package lithium battery aluminum-plastic film manual sealing machine

Abstract

The invention discloses an improved soft package lithium battery aluminum-plastic film manual sealing machine. The manual sealing machine comprises a sealing machine body and a PLC, the PLC is arranged on the front end face of the sealing machine body, a display is arranged above the PLC, a timer is arranged on the right side of the display, a sealing air cylinder is arranged in the sealing machine body, a sealing connecting plate is connected to the lower end of the sealing air cylinder, an adjusting plate is arranged on the left side of the sealing connecting plate, an adjusting sliding block is arranged on the surface of the adjusting plate, an adjusting guide rail is arranged outside the adjusting sliding block, a supporting column is connected to the lower end of the sealing connecting plate, and an adjusting top plate is arranged at the lower end of the supporting column. According to the improved soft package lithium battery aluminum-plastic film manual sealing machine, through the arrangement of the adjusting sliding block and the adjusting guide rail, a traditional linear guide column structure can be replaced, precision is improved, meanwhile, movement of the sealing connecting plate can be limited, and the device is more stable.

Description

technical field [0001] The invention relates to the technical field of sealing machines, in particular to an improved aluminum-plastic film manual sealing machine for soft-pack lithium batteries. Background technique [0002] The simple edge banding machine is widely used in the production of soft-pack lithium batteries. The aluminum-plastic film is pressurized by using copper bars heated up and down, so that the inner layer of the aluminum-plastic film can be fused together. In the field of lithium batteries, the thickness of the aluminum-plastic film edge sealing is particularly important to the stability of the battery: thick thickness will easily lead to gas leakage and electrolyte leakage; if the thickness is too low, the aluminum-plastic film adhesive layer will be over-melted, causing short circuit and corrosion. [0003] The existing sealing machine has large precision error and difficult adjustment. It is difficult to control the thickness deviation of the aluminum-...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an improved soft-packed lithium battery aluminum-plastic film manual sealing machine to solve the problem of the existing sealing machine proposed in the above-mentioned background technology. The control is within the range, and a single cylinder is used to control the sealing pressure. The sealing on both sides is not balanced, which cannot meet people's needs.
