Description

Assembling device for terminal plug feeding and transferring carrier

Technical Field

The invention belongs to the technical field of automatic assembly and relates to an assembly device for a terminal plug feeding and transferring carrier.

Background

The terminal plug has the advantages of large information transmission capacity, stability, reliability, large data carrying capacity, wide application and large production. For example, terminals with different transmission paths from 9 pins to 50 pins are sleeved with anti-loosening and anti-vibration pads and then are installed in the bracket, then the iron shell and the bracket are buckled with each other, and finally the hexagonal nut is riveted and fixed to form the anti-loosening and anti-vibration connector. This type of terminal 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 terminal plug and the male plug are poor in electrified contact matching degree, 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 horizontally converted into a vertical posture and a vertical posture for corresponding assembly for many 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 defects that the installation and turnover 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 is easily generated among the hexagonal nut, the iron shell and the support, leveling processing and inspection steps have to be added in subsequent processes, and cost is increased.

Up to now, there has been no successful application and patent application for the assembly of the loading and circulation carrier of the terminal plug (data plug or iron case plug).
