Problems solved by technology

This type of top mechanism feeds materials from top to bottom. During the production process of the battery, the length of the tab aluminum strip or the length of the tab tape will be inconsistent, resulting in welding with the cap on the tab tape or the area of ​​the welded aluminum strip. less problems exist
Specifically, it is manifested in the following two aspects: the long tab tape will be welded on the tab tape, resulting in false welding; the short tab aluminum strip, the welding area is only a part of the tab aluminum strip, resulting in high internal resistance of the battery

Abstract

The invention discloses a capping machine electrode lug positioning and welding mechanism which comprises a feeding mechanism mounted on a feeding frame. An upward-jacking mechanism is arranged at the end of the feeding frame, an ultrasonic welding head for welding and an adhesive tape sensor for sensing an adhesive tape are arranged above the upward-jacking mechanism, the adhesive tape sensor is matched with a welding position, the upward-jacking mechanism comprises a fixing vertical plate, a cam rotating motor and a battery fixing seat, the fixing vertical plate is mounted at the bottom of the outer end of the feeding frame, and the cam rotating motor is mounted on the fixing vertical plate and connected with the battery fixing seat through a cam linkage mechanism and drives the battery fixing seat to drive a battery to move up and down. The capping machine electrode lug positioning and welding mechanism has the advantages of simple structure, low cost, convenience in manufacturing and using, high applicability, accuracy in upward-jacking feeding of the battery and high welding pass rate.

Description

technical field [0001] The invention relates to a capping machine, in particular to a positioning welding mechanism for tabs of a capping machine. Background technique [0002] At present, the positioning welding of the tabs of the traditional capping machine mainly includes a feeding mechanism, a lifting mechanism and an ultrasonic welding head. The lifting mechanism uses a cylinder as a power source to drive the battery to rise, and its movement height is fixed and cannot be adjusted. The height of the battery's up and down movement is positioned with the steel case of the battery. This type of top mechanism feeds materials from top to bottom. During the production process of the battery, the length of the tab aluminum strip or the length of the tab tape will be inconsistent, resulting in welding with the cap on the tab tape or the area of ​​the welded aluminum strip. Few other problems exist. Specifically, it is manifested in the following two aspects: the tab tape that...
