A kind of pouch battery lamination hot pressing device

Abstract

The invention discloses a pouch battery lamination heat-pressing device, which comprises a frame, a lamination part and a heat-pressing part arranged on the upper end of the frame, the lamination part includes a bracket slidingly connected with the frame, and the support The upper end is provided with a line body, the upper end of the line body is provided with a push plate, and the push plate is slidably connected with the bracket through the second linear motion device, and the hot pressing part includes a support frame, and the support frame is arranged at the upper end of the frame and is far away from the frame. On one side of the push plate, the support frame is provided with a hot-press top plate and a heat-press bottom plate. The heat-press top plate is located above the heat-press bottom plate and is connected to the support frame by sliding up and down through the first linear motion device. The present invention can quickly Efficient stacking of cells, the stability of the position of the cells during the stacking process, and the transfer of the cells from the stacking part to the hot pressing part can effectively prevent dark marks during the transfer of the cells Or wrinkle phenomenon, which ensures the uniformity of hot pressing and improves the production quality of battery hot pressing.

Description

technical field [0001] The invention relates to the technical field of battery production equipment, in particular to a hot-pressing device for pouch battery stacks. Background technique [0002] In recent years, with the country's strong support for the new energy battery industry, the lithium-ion battery manufacturing industry has experienced unprecedented development. In this environment, the requirements for the energy density and production efficiency of lithium-ion batteries are becoming more and more stringent. Therefore, it is necessary to strengthen the control of each production process of battery production, improve the product production efficiency of each production process, and Battery energy density. [0003] The structure of the soft-pack lithium battery is packaged with aluminum-plastic film. In the event of a safety hazard, it will not explode like a steel case or an aluminum case battery. The soft-pack battery will only blow up and crack at most. In addi...

Problems solved by technology

[0004] However, the pouch battery is soft and large in size. After lamination, it is picked up by the manipulator and put into the built-in splint of the hot-pressing platform. The splint lifts the battery and moves down to the hot-pressing platform for hot-pressing. The splint is not heated.

According to the survey, after the hot pressing of the pouch battery, there is often a problem of uneven hot pressing, which leads to dark marks or even wrinkles on the surface of the battery cell.

In order to solve the problems of difficult movement of pouch batteries and uneven heat pressing, it is very necessary to design a new type of battery lamination heat pressing equipment with high efficiency, not easy to damage the battery and complete functions.
