Spot soldering fixture and spot soldering process

Abstract

The invention belongs to the technical field of soldering, and particularly relates to a spot soldering fixture, which is used in a spot soldering process capable of avoiding pseudo soldering, false soldering and bursting, and is high in soldering efficiency. The spot soldering fixture comprises a fixture body, a cell storage area and a fuse storage area, and an avoidance hole is reserved between the cell storage area and the fuse storage area. Compared with the prior art, the spot soldering fixture has the advantages that a fuse and a metal strap can be effectively positioned, the height of a soldering pin can be adjusted, spot soldering quality can be improved, soldering reject ratio can be decreased, production efficiency can be improved, and cost can be saved. Besides, the invention further discloses the spot soldering process using the spot soldering fixture.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to a spot welding process and a spot welding fixture used therein which can avoid virtual welding, false welding and explosion and have high welding efficiency. Background technique [0002] With the continuous development of electronic equipment, the battery as the power supply of the electronic equipment has also been greatly developed; and with the miniaturization of the electronic equipment, the battery is also correspondingly developing towards thinner and lighter weight. [0003] A battery generally includes a cell, a protective plate located at the front of the cell, and other related structural components, such as a front cover, a rear cover, and a casing. A fuse is generally installed on the protection board. When the temperature of the battery rises to a certain temperature, the fuse is disconnected to prevent the battery from exploding. The connection betwee...

Problems solved by technology

However, since the bumps of the copper feet of the fuse are set upwards, and the aluminum-nickel composite strip has a double-layer structure, it is difficult to spot weld, which may easily lead to false welding or false welding, and the pulling force cannot meet the requirements, so Prone to a large number of defective products, affecting product quality

In addition, false welding and false welding need special personnel to select them before repairing welding, which is time-consuming and labor-intensive, and affects production capacity.

[0005] In addition, increasing the energy output and other related parameters of the spot welding equipment can avoid false welding and virtual welding, but it will also cause undesirable phenomena such as over-welding, explosion and welding penetration.

Among them, the fire explosion is particularly serious, resulting in the scrapping of the fuse, low material utilization rate, and low efficiency. The fire explosion phenomenon causes sparks to splash, which may damage adjacent devices and even injure the operator.
