Description

Full-automatic punching and welding assembly system of iron shell plug

Technical Field

The invention belongs to the technical field of automatic assembly and relates to a full-automatic punching and welding assembly system for an iron shell plug.

Background

The iron shell plug has the advantages of large information transmission capacity, stability, reliability, large data carrying capacity, wide application and large production. For example, terminals and insulating terminals with different transmission paths from 9 pins to 50 pins are sleeved with anti-loosening and anti-vibration pads and installed in the bracket, the iron shell and the bracket are buckled with each other, and finally, the hexagonal nut is riveted and fixed to be formed. This type of iron-clad plug mainly adopts manual assembly at present, and the tailor of iron-clad adopts automatic processing and semi-automatic processing with the riveting process, mainly includes following not enough:

1) the iron shell and the bracket are large in cutting burrs and poor in cutting size consistency, so that the iron shell and the bracket are staggered back and forth after assembly, the hot-line contact adaptability of a terminal product and a male plug is poor, and short circuit and poor data and information transmission are caused; the product return rate is 7-15%, and the rework rate is 18-20%. 2) The anti-loose anti-vibration pad is easy to be neglected to be installed or not installed in place to cause falling off. 3) In the existing assembly mode, the iron shell, the support and the terminal need to be assembled in a posture that the iron shell, the support and the terminal are vertically and vertically converted into a horizontal posture for multiple times, and the signal transmission needle head of the terminal is often deformed and broken, so that the rework rate and the rejection rate of the terminal are high, and the service life is short. 4) The iron shell and the support are riveted and fixed through the hexagon nut, and in a large number of industrial application occasions, because the vibration makes clearance between the iron shell and the support, the iron shell and the support make the terminal and the matching plug loose along with the vibration for information data transmission is unstable. 5) Because the iron shell, the bracket and the terminal have the reasons that the installation and overturning directions cannot be identified and the terminal pin is easy to damage, the automatic feeding is difficult to implement. 6) The iron shell, the support and the hexagonal nut of the data plug are riveted through two processes, one-step forming is not needed, warping between the hexagonal nut and the iron shell and between the hexagonal nut and the support is generated, leveling processing and inspection steps have to be added in subsequent processes, and cost is increased.

Up to now, there is no successful research, development, application and patent application for the full-automatic punching welding and full-automatic assembling equipment of the iron shell plug.
