Spot welding jig suitable for super capacitor

The spot welding jig suitable for the super capacitor comprises an installation bottom plate, a sliding guide rail and limiting assemblies are arranged on the installation bottom plate, the limiting assemblies are arranged at the two ends of the sliding guide rail respectively, a sliding assembly is arranged on the sliding guide rail, and the limiting assemblies are arranged at the two ends of the sliding guide rail respectively. The sliding assembly is provided with a super capacitor installation position. According to the spot welding jig suitable for the super capacitor, through the combination of the sliding guide rail and the limiting assembly, the moving range of the super capacitor is precisely limited, the positioning accuracy of the super capacitor in the spot welding process is improved, and the welding quality is ensured; and meanwhile, the super capacitor can be positioned only by moving in a limited range, so that the positioning efficiency of the super capacitor in the spot welding process is ef
