Problems solved by technology

If the positioning accuracy is poor, the assembly quality will be unstable; if the structure of the fixture is unreasonable, it will affect the electrical conductivity and welding strength of the winding core to varying degrees during assembly.
[0004] In the prior art, there is a tooling fixture with a three-jaw structure, which shrinks and clamps the winding core by shrinking the three-jaw fixing ring and makes close contact with the current collector. However, since the three claws move and clamp the winding core at the same time, friction between each other, the eccentricity of the winding core and the current collector often occurs during use, which cannot meet the production process requirements
In addition, the fixture cannot meet the needs of welding cores and current collectors of different heights.

Abstract

The invention provides a current collecting piece welding device, a lower current collecting piece welding device and a fixture of the lower current collecting piece welding device. The fixture comprises a base, a guide block, a winding core support block, a fixture barrel and an upper cover; a centering groove and a through hole are formed in the center of the support block; the fixture barrel is arranged outside the guide block and the winding core support block in a covering manner; the fixture barrel is provided with centering parts; a through hole needed for laser welding is formed in the bottom wall of the upper cover, and fastener grooves are formed in the side wall; bosses are arranged on the peripheral well of the fixture clamp. The fixture has the advantages that since the support block with the center provided with the centering groove and the fixture barrel provided with the centering parts are arranged at two ends of a winding core of a supercapacitor to be processed respectively, the winding core of the supercapacitor to be processed can be positioned from the upper and lower portions accurately; meanwhile, by the aid of the support block, the fixture is suitable for welding of supercapacitor winding cores and current collecting pieces with different heights and convenient for changing the line of production, and labor-hour and cost are saved.

Description

technical field [0001] The invention relates to a fixture, in particular to a fixture used for welding supercapacitor current collectors. Background technique [0002] In the production process of welded supercapacitors, there is usually a process of welding the upper and lower current collectors with the winding core by laser welding, and leading out the positive and negative poles of the winding core, which has good electrical conductivity and welding strength. , this process is crucial to the quality of the product. [0003] For laser welding, the positioning accuracy of the welding position of the supercapacitor winding core is the most basic factor affecting its assembly quality. Most of the positioning methods in the prior art use fixtures to position the welding position. Then, whether the design of the fixture is reasonable or not has a great influence on the quality of electronic components. If the positioning accuracy is poor, the assembly quality will be unstabl...
