Fixing fixture for tin fillet scroll

Abstract

The invention relates to the technical field of tin fillet scroll fixing, in particular to a fixing fixture for a tin fillet scroll. The fixing fixture comprises a torsion nut arranged in a chamber of a torsion ring, an inner thread of the torsion nut is matched with an outer thread formed in a pay-off and take-up motor shaft, a through hole used for allowing a shaft body of the pay-off and take-up motor shaft to penetrate is formed in the torsion ring, the periphery of the torsion nut is provided with grooves in the circumferential direction at intervals, and a convex part is formed between every two adjacent grooves; the torsion ring and the torsion nut are connected through an ejecting card and a spring, one end of the ejecting card is clamped in one groove, the end face of the end, clamped in the groove, of the ejecting card is an oblique face, the other end of the ejecting card is connected with the spring, and the spring is arranged in the torsion ring; the outer surface of each convex part is provided with a circumferential guide groove, the end, where the oblique face is located, of the ejecting card is provided with a guide block, and the guide block is matched with the guide grooves. According to the fixing fixture, the torsion nut is driven by the torsion ring, the ejecting card and the spring to be screwed, after the torsion nut is screwed to the limit, the torsion ring and the ejecting card generate a slip phenomenon, and then firm fixation on the tin fillet scroll is achieved.

Description

technical field [0001] The invention relates to the technical field of fixing a tin ribbon reel, in particular to a fixing fixture for a tin ribbon reel. Background technique [0002] Photovoltaic tin ribbon is one of the very important components in solar modules. The finished tin ribbon is wound on a reel. When the tin ribbon is manufactured, the reel needs to be fixed on the winding motor. When the winding motor is working, the winding motor shaft For rotation and linear movement, the spool is fixed on the motor shaft of the take-up and discharge motor and rotates with it to achieve the purpose of take-up and take-off. Among them, the stability of the reel fixation has a great influence on the quality of the take-up and pay-off of the tin ribbon. In the prior art, the reel is usually directly fixed by a nut, but when the reel is fixed with an ordinary nut, the pressure on the reel is unstable, resulting in The fixed tightness is different, which affects the take-up and r...

Problems solved by technology

Among them, the stability of the fixed reel has a great influence on the quality of the take-up and pay-off of the tin ribbon. In the prior art, the reel is usually directly fixed by a nut, but when the reel is fixed with an ordinary nut, the pressure on the reel is unstable, resulting in The tightness of the fixing is different, which affects the take-up and release of the tin ribbon, which is easy to cause twisted ribbons, resulting in disordered wiring, defective products, and waste of resources
