A cell lamination production line and lamination method

Abstract

The invention discloses a cell lamination production line and a lamination method. The lamination table reciprocates between the left station of the lamination table and the right station of the lamination table, and the left secondary alignment component is arranged on the lamination table. On the extension line of the moving direction; the right secondary alignment assembly is set along the vertical direction of the lamination table moving direction; the right material box assembly is set on one side of the right secondary alignment assembly, coaxial with the right secondary alignment assembly Setting; the rotary transport lifting assembly is arranged between the right secondary alignment assembly and the right station of the lamination table, and is used to transport the pole pieces of the right secondary alignment assembly to the right station of the lamination table. According to a cell stacking production line and stacking method of the present invention, the pole piece on the right secondary alignment component is transported to the stacking platform by the rotating lifting component, so that the right pole piece is transported more efficiently and greatly Minimize the time for lamination handling, thereby increasing the output of the production line. After the left secondary alignment assembly and the right secondary alignment assembly are arranged separately, it is more convenient for maintenance and replacement.

Description

technical field [0001] The invention relates to the technical field of cell lamination production, in particular to a cell lamination production line and a lamination method. Background technique [0002] With the rapid development of new energy electric vehicles, the demand for automotive power batteries in the automotive industry is increasing. In the manufacturing process of automotive power batteries, a stacking machine is usually used to stack the positive and negative electrodes at intervals to form battery cells. In the commonly used lithium-ion battery cell stacking machine, first use the suction cup to absorb the positive or negative electrode sheet from the material box, and move it to the corresponding positioning platform. Pole piece, and moved to the lamination table to complete the lamination. [0003] At present, the production process of automotive power batteries is carried out by lamination machine production line. The battery pole pieces are continuously ...

AI Technical Summary

Problems solved by technology

With the rapid development of automobile power batteries, the structure of power batteries has also developed various forms. Among them, the pole piece specifications of the blade battery are about 100mm in width and more than 500mm in length. The positive and negative pole pieces on the traditional stacker production line The handling process is too long. Since the production line adopts an automated assembly line, the time for the manipulator to carry the stacks is fixed, and the handling efficiency of the stacks also directly affects the output of the power battery.
