Problems solved by technology

[0002] At present, in the field of battery production, in many cases, it is necessary to weld the positive temperature coefficient thermistor to the pad of the battery protection board by resistance welding. The traditional method is to divide the combined common board first. Work, and then manually place the thermistor on a battery protection board, so that the centers of the protruding tabs on both sides of the thermistor are aligned with the centers of the two pads on the battery protection board, and the tabs on one side are spot-welded first. Then move the protection board and the thermistor to the appropriate position, and spot weld the other side. After finishing one, process the other. Because the positioning of the thermistor on the battery protection board is difficult, and it is produced individually, the position of the spot welding is not correct. Accurate, low quality, slow production

Abstract

The invention discloses a clamp and method for quickly carrying out spot welding of a thermistor on a cell protective board. The clamp comprises an object base, a locating plate and a press plate, wherein one side of the press plate is hinged with one side of the object base through a pin shaft, one side of the locating plate is hinged with one side of the object base through a pin shaft, the locating plate is arranged on the press plate in a crossing manner, the object base is provided with a pit for containing a splice plate, a crossed part of the press plate and the locating plate is provided with a through hole, and the locating plate is provided with at least one locating through hole for allowing the implant of the thermistor. According to the clamp and method for quickly carrying out the spot welding of the thermistor on the cell protective board, disclosed by the invention, the cell protective board and a plurality of thermistors can be precisely clamped and located in one step so as to realize the precise location and the spot welding at a plurality of positions by matching with manual spot welding; and a board separation operation is carried out after the spot welding of the thermistors on the cell protective boards is continuously finished so that the production efficiency is largely improved.

Description

technical field [0001] The invention relates to the technical field of lithium-ion batteries, in particular to a fixture and a method for quickly spot-welding a thermistor to a battery protection plate. Background technique [0002] At present, in the field of battery production, in many cases, it is necessary to weld the positive temperature coefficient thermistor to the pad of the battery protection board by means of resistance welding. The traditional method is to divide the combined common board first. Work, and then manually place the thermistor on a battery protection board so that the centers of the protruding tabs on both sides of the thermistor are aligned with the centers of the two pads on the battery protection board, and spot weld the tabs on one side first. Then move the protection board and the thermistor to the appropriate position, and spot weld the other side. After finishing one, process the other. Because the thermistor is difficult to locate on the batte...
