Automatic film-enveloping and piece-laminating machine

Abstract

The invention relates to an automatic film-enveloping and piece-laminating machine. The machine comprises a stander, a lower diaphragm unreeling device, an upper diaphragm unreeling device, a piece-feeding device, a piece-moving device, a sealing-pressing device, a shearing device and a piece-laminating device, wherein long-strip-shaped piece-moving platforms are arranged on the stander; the piece-feeding device comprises sucking disc piece-fetching mechanisms and a piece-feeding translation mechanism; the piece-moving device comprises a clamp plate translation mechanism, piece-moving substrates, clamp plate air cylinders, base plates and clamp plates; the sealing-pressing device comprises a heat-seal assembly and a heat-seal lifting mechanism, the heat-seal assembly is located above the piece-moving platforms, and the heat-seal lifting mechanism is used for driving the rising and the falling of the heat-seal assembly; the piece-laminating device comprises sucking disc piece-fetching mechanisms, a piece-laminating translation mechanism and piece-collecting mechanisms, and the piece-laminating translation mechanism is used for driving the sucking disc piece-fetching mechanisms to carry out translational motion. According to the automatic film-enveloping and piece-laminating machine, the full automation is realized during film-enveloping, heat-seal, shearing and piece-laminating processes, the film-enveloping precision is high, the film-enveloping speed is high, and the film-enveloping effect is good.

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.
