Problems solved by technology

The main problem of this welding method is that the welding is carried out without fixtures. Because the shells are all rectangular, the wall thickness of the shell is only about 5mm, and the length is 300-400mm. When the hot plate is welded and sealed, four The stress on each corner is uniform, but the stress on the solder joints of each intermediate wall is uneven, the welding seam is easily deformed and dislocated, the welding is not strong, and even air leaks, resulting in waste of raw materials and increased costs for re-welding

Embodiment Construction

[0007] The embodiment is described in detail in conjunction with the accompanying drawings, which includes two strip-shaped splints 2, and a space that can be loaded into the battery case is vacated in the middle of each strip-shaped splint near the two ends, and a bolt with a nut 4 at one end is respectively connected. 1. A baffle plate 3 is horizontally and vertically installed in the middle of the outer surfaces of the two splints. There is a screw rod transverse inlet and outlet 5 at the corresponding place of a bolt on one of the splint side walls. When in use, first unscrew the nuts on both sides, put a certain distance between the mouth of the battery case and put it between the two splints, adjust the position so that the splint is close to the outer wall of the case, and then tighten the nuts on both sides, you can use the hot welding plate. Seal welding. It has the advantages of flexible and convenient use, uniform stress on the welding surface, and guaranteed weldi...

Abstract

The invention discloses an alkaline pocket type battery shell seal welding fixture, which comprises two strip-type clamping plates, wherein a space, capable of containing a battery shell, close to each of two ends, is formed in the middle of each strip-type clamping plate, the space is provided with two bolts with a nut on one end, a baffle plate is perpendicularly mounted on the middle part of the outer surface of each of the two clamping plates in a transverse direction; a screw lateral inlet/outlet is formed at the position corresponding to the bolt on the side wall of one of the clamping plates. According to the alkaline pocket type battery shell seal welding fixture disclosed by the invention, the clamping plates and the adjusting bolts are used for fixing and limiting a workpiece tobe welded and then performing hot plate welding and sealing, so that the welding surface can be evenly stressed, the phenomena of deformation, dislocation and air leakage are prevented, and the welding quality is ensured; the alkaline pocket type battery shell seal welding fixture has the advantages that the use is flexible and convenient, the working efficiency is improved and waste is avoided.

Description

technical field [0001] The invention relates to a clamping and fixing element, in particular to a flexible and convenient alkaline bag-type accumulator case sealing welding jig which can improve the sealing quality. Background technique [0002] Alkaline battery case and cover plate are made of polypropylene plastic. Hot plate welding machine is used for sealing during the battery production process. During welding, the heating plate is placed between two plastic parts. When the body is close to the heating plate, the contact surface of the plastic parts begins to melt. When the two plastic parts reach a certain degree of melting, the two workpieces are separated, the heating plate is removed, and the melting surfaces of the two workpieces are combined. The main problem of this welding method is that the welding is carried out without fixtures. Because the shells are all rectangular, the wall thickness of the shell is only about 5mm, and the length is 300-400mm. When the hot...
