The bead is pressed tightly in the middle of the positive and negative busbars, and the two sides of the bead are close to the edges of the positive and negative tabs. There is no welding allowance gap, and it is difficult to burn through the lugs that are close to the edge of the bead. If the welding is unqualified, it is necessary to reinstall the electrode group on the welding mold for repair welding, which is time-consuming and expensive, and affects production efficiency

The invention discloses a device for preventing false welding of batteries, which comprises a fixed template, a movable template and a bead. The fixed template and the movable template are provided with pole positioning grooves and busbar grooves. There are several tooth grooves, and there is a gap A between the length direction of the tooth groove and the edge of the bus groove; the layer is composed of left and right layers, the left layer is provided with a slot, and the right layer is provided with a boss, and the missing groove and the boss There is a rotating shaft connection in the middle of the two, and a B gap is provided between the bead and the edge of the bus bar. The invention is simple in structure and easy to operate, ensures that the tabs of the bus bar are not exposed, enhances the bonding force between the tabs and the bus bar, and avoids the phenomenon of product quality degradation caused by the deformation of the tabs caused by beating the bead, and the repair rate is low, improving Improve welding quality and production efficiency.
Description
technical field [0001] The invention relates to the field of storage battery production, in particular to a device for preventing the storage battery from burning and welding. Background technique [0002] The electrode group welding process in the battery manufacturing process is to first install the electrode group on the comb mold, and then beat the bead to press it into the positive and negative molds and then perform welding. The bead is pressed tightly in the middle of the positive and negative busbars, and the two sides of the bead are close to the edges of the positive and negative tabs. There is no welding allowance gap, and it is difficult to burn through the lugs that are close to the edge of the bead. If the welding is unqualified, it is necessary to reinstall the electrode group on the welding mold for repair welding, which is time-consuming and expensive, and affects production efficiency. Contents of the invention [0003] The technical problem to be solved...
