A clamping device and a welding module of a self-restoring fuse thereof

Abstract

The invention discloses a clamping device and a welding module of a self-restoring fuse thereof, comprising a clamping fixing housing, a clamping pushing assembly, a driving mounting assembly, a firstdriving assembly, a second driving assembly, a first clamping jaw and a second clamping jaw. The invention relates to a clamping device and a welding module of a self-restoring fuse thereof. The clamping pushing assembly, the first jaw and the second jaw are provided, so that the self-restoring fuse can be clamped in a direction that is easy to weld, weld is convenient, and no virtual solderingoccurs. The invention ensures that the pins can be soldered on the body of the self-restoring fuse accurately, ensures that the pins can have good contact with the chip inside the self-restoring fuse,improves the quality of the self-restoring fuse, ensures that the self-restoring fuse can be attached on the circuit board to realize its protection function, and reduces the probability of the circuit board failure.

Description

technical field [0001] The invention relates to the field of automatic production of self-resetting fuses, in particular to a clamping device and a welding module for self-resetting fuses. Background technique [0002] At present, the welding module is suitable for the welding requirements of coating materials and aluminum alloy materials, and the development of resistance welding machines for precision parts welding has attracted more attention. The development of testing technology and testing equipment will help to promote the improvement of enterprise technology and technical level. [0003] However, in the process of producing the resettable fuse, it is necessary to weld the pins of the resettable fuse to the body of the resettable fuse, and the resettable fuse needs to be fixed on the fixture before welding the pins to the resettable fuse. However, most of the existing fixtures place the self-recovery fuse on the fixture, that is, the existing self-recovery fuse needs...

Problems solved by technology

[0003] However, in the process of producing the resettable fuse, it is necessary to weld the pins of the resettable fuse to the body of the resettable fuse, and the resettable fuse needs to be fixed on the fixture before welding the pins to the resettable fuse. However, most of the existing fixtures place the self-recovery fuse on the fixture, that is, the existing self-recovery fuse needs to be placed flat on the fixture of the fixture. Since the pins are tin wires and have a certain welding angle, therefore, The self-resetting fuse placed on the fixture is difficult to solder accurately, and it cannot be guaranteed that the pins can have good contact with the chip inside the self-resetting fuse. Therefore, there may be a problem of weak soldering of the pins, which reduces the quality of the self-resetting fuse. , which also causes the self-recovery fuse to fail to achieve its protection function even if it is mounted on the circuit board, which increases the probability of circuit board failure
