Automatic film stacking machine

Abstract

The invention relates to an automatic film lamination machine, comprising a frame, a lower diaphragm unwinding device, an upper diaphragm unwinding device, a sheet feeding device, a sheet moving device, a sealing and pressing device, a shearing device and a lamination device; the frame There is a strip-shaped sheet-moving platform; the film-feeding device includes a suction cup film-taking mechanism and a film-feeding translation mechanism; the film-moving device includes a splint translation mechanism, a film-moving substrate, a splint cylinder, a bottom plate and a splint; a splint cylinder, a bottom plate and a splint It is arranged on the transfer substrate; the bottom plates are arranged in pairs, and are respectively located on both sides of the transfer platform; the sealing and pressure device includes a heat-sealing assembly located above the transfer platform and a heat-sealing lifting mechanism for driving the heat-sealing assembly up and down; The sheet device includes a suction cup sheet taking mechanism of the sheet stacking device, a stack translation mechanism and a sheet receiving mechanism for driving the suction cup sheet taking mechanism to translate. The automatic coating lamination machine of the present invention realizes the full automation of coating, heat sealing, cutting and lamination processes, and has high coating precision, fast speed and good effect.

Description

technical field [0001] The invention relates to a coating and stacking equipment of a lithium battery, belonging to the technical field of battery production equipment. Background technique [0002] Due to the increasing scarcity of energy and the enhancement of people's awareness of environmental protection, lithium batteries are becoming more and more popular in the market due to their environmental protection, safety and pollution-free advantages. During the production process of the lithium battery cell electrode group, the positive electrode sheet and the negative electrode sheet need to be stacked alternately layer by layer, and the adjacent positive electrode sheet and negative electrode sheet are separated by a thin film, and then the neatly stacked electrode groups are bundled. At present, lithium battery manufacturers use independent equipment to complete the operations in the coating process and lamination process, and the coating equipment usually uses a single-p...

Problems solved by technology

In this coating method, the material tape is cut at the end, and the middle is continuous. The coating effect is not good, and problems are prone to occur when unwinding and tableting. Once a problem occurs in the middle, it must be restarted.
