Abstract

The invention belongs to the technical field of coating or plating equipment by means of brazing or welding methods, and in particular discloses a battery spot welding device. The battery spot weldingdevice comprises a rack and a worktable, wherein the worktable is located below the rack; a hydraulic cylinder is fixedly mounted on the rack; the output end of the hydraulic cylinder is fixedly connected to a spot-welder; a spot-welding needle is fixedly mounted on the lower end surface of the spot-welder; a part feeding mechanism is fixedly mounted on the upper end surface of the worktable; thepart feeding mechanism is used for driving a protecting plate and a battery cell to move in opposite directions till the protecting plate and the battery cell are laminated; the part feeding mechanism is driven by the spot-welder; a glue spraying mechanism is arranged in the part feeding mechanism for spraying glue to the battery cell; and the glue spraying mechanism is driven by the part feedingmechanism. The battery spot welding device aims to solve the problems that the efficiency is low and the safety cannot be ensured as the battery cell and the protecting plate are manually held to weld in the prior art.

Description

technical field

[0001] The invention belongs to the technical field of cladding or plating equipment by means of brazing or welding, and specifically discloses a battery spot welding device. Background technique

[0002] In the production process of lithium batteries, after the battery cell is manufactured, the protective plate needs to be installed on the battery cell. At present, the protective plate is usually fixedly connected to the battery cell by spot welding, but in the spot welding process of the protective plate, Workers need to hold the battery cell in one hand and the protective plate in the other, and then weld with an electric spot welder, which has the problem of low welding efficiency. At the same time, the high temperature and current generated during welding pose a threat to the life safety of workers. Contents of the invention

[0003] The invention discloses a battery electric welding device, aiming to solve the problem of low efficiency and unsafety in...
