PIN spot-welding mechanism and automobile coil winding spot-welding assembly line

Abstract

The invention provides an automobile coil spot-welding assembly line. The assembly line comprises a PIN spot-welding mechanism, the spot-welding mechanism comprises a public electrode module and a polarization module; the public electrode module comprises a public electrode plate and a public electrode mounting base; the public electrode plate is arranged on the public electrode mounting base, a first electric connecting part is arranged on the public electrode plate, and a first water-cooling pipe is arranged in the public electrode mounting seat; and the polarization module comprises a polarization plate, a polarization mounting base and a mobile module; the polarization plate is arranged on the polarization mounting base, a second electric connecting part is arranged on the polarizationplate, an outer tip of the polarization plate is located outside of the polarization mounting base, and the outer tip of the polarization plate is towards the public electrode plate, a second water-cooling pipe is arranged in the first electrode mounting base, the mobile module is used for driving the polarization mounting base to move towards the public electrode plate, and the polarization module is located on the side of the public electrode plate in the extending direction. By adopting the structure, the spot-welding precision is higher, and the cooling effect is better.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a PIN needle spot welding mechanism and an automobile coil winding spot welding assembly line. Background technique [0002] In the process of producing automotive coils, it is necessary to install the PIN needle on the skeleton, and then wind the skeleton and the PIN needle on the skeleton. The degree of curvature facilitates closer contact between the PIN pin and the enameled wire on the PIN pin. After the notch of the PIN pin is pre-pressed, in order to prevent the enameled wire on the PIN pin from falling off, the gap on the PIN pin needs to be sealed and spot-welded. Since the gap of the PIN needle is small, and the PIN needle is thin, if the gap of the PIN needle is spot-welded by solder spot welding, the amount of solder is difficult to control, and the spot welding steps are numerous, and it is difficult to control the accuracy. The obtained PIN needle has The thickn...

Problems solved by technology

Since the gap of the PIN needle is small, and the PIN needle is thin, if the gap of the PIN needle is spot-welded by solder spot welding, the amount of solder is difficult to control, and the spot welding steps are numerous, and it is difficult to control the accuracy. The obtained PIN needle has The thickness may increase, which will cause inconvenience to the use of the coil in the later stage

During the welding process, it is often necessary to cool the welding head, and the existing common cooling methods are air cooling or water cooling. The main method of water cooling is to arrange water pipes outside the welding head. , not only the cooling effect is average, but the appearance of the device is not simple enough
