Abstract

Battery cell flattening equipment for a lithium battery production process comprises a working cabin, a discharging assembly, a conveying assembly, a flattening assembly, an unloading assembly, a laser positioner assembly and a controller. The conveying assembly is arranged in the working cabin; the discharging assembly is arranged above the feeding end of the conveying assembly; the flattening assembly is arranged in the working cabin; and the discharging assembly is arranged below the discharging end of the conveying assembly. Efficient circulation of discharging, flattening and dischargingis achieved, and automation performance is high; a die and an extrusion plate are convenient to mount and dismount; a battery cell is softened in a heating mode, the difficulty of a flattening processis reduced, cold air is supplied to the flattened battery cell to help the flattened battery cell to be cooled, the purpose of rapid shaping is achieved, and the stability of a flattening effect is guaranteed; the central position of the battery cell is extruded by the extrusion plate, and the edge of the battery cell is rotatably extruded by an extrusion roller so that the battery cell is uniformly stressed, and the flattened battery cell is uniform in thickness; and the fixed seat is rotatably matched and knocked so that the stress is uniform, and a discharging speed is increased.

Description

technical field [0001] The invention relates to the field of lithium battery production, in particular to battery cell flattening equipment for the lithium battery production process. Background technique [0002] Lithium-ion battery is a high-performance secondary battery, which has the advantages of high working voltage, high volume and weight energy density, long life, low self-discharge rate, no memory effect and good for the environment. It is widely used in mobile communication equipment, Notebook computers, camcorders, PDAs (personal digital assistants), digital cameras, power tools, torpedoes, missiles and other fields. In the manufacture of lithium-ion batteries, there is a process of "into the shell", that is, to put the battery core body wound by the positive and negative electrodes into the shell. Since different types of batteries have different size requirements for the positive and negative electrodes, a certain reserved space must be kept in the shell to ens...
