A fully automatic loader for strain gauges of terminals

Abstract

The invention relates to a full automatic strain gauge loader of a terminal. The loader comprises a main body rack and a rack bottom plate, wherein the upper end of the rack bottom plate is provided with a terminal feeding device, the tail end of the terminal feeding device abuts on a terminal conveying slideway device, one side of the terminal conveying slideway device is, from left to right, sequentially provided with a glue dispensing device, a strain gauge unloading device and a terminal fixing device, and the other side of the terminal conveying slideway device is sequentially provided with a strain gauge conveying device, a pressing device and a human-computer interface; the glue dispensing device is connected to the strain gauge feeding device, and the strain gauge conveying deviceis positioned between the glue dispensing device and the strain gauge unloading device. According to the full automatic strain gauge loader of the terminal, the terminal is conveyed through the terminal conveying slideway device, a strain gauge is clamped by a receiving head of a front-rear clamping mechanism to the lower part of a glue dispensing head, thus completing glue dispensing; in addition, a left-right movable mechanism conveys the strain gauge to the lower part of the strain gauge unloading device, so that an unloading head of the strain gauge unloading device descends and then penetrates through an inner ring of the strain gauge, the receiving head is retracted, and finally the strain gauge is lowered on the terminal along the unloading head. To conclude, the loader has the advantages of compact structure and high automation degree.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a fully automatic loader for strain gauges of terminals. Background technique [0002] Strain gauges, also known as strain gauges, are components used to measure strain composed of sensitive grids, which can convert changes in strain on mechanical components into changes in resistance. As sensing elements, strain gauges need to be firmly pasted on the components. At the measuring point, the pressurization method after the strain gauge is pasted on the test piece (such as an elastic ring) is determined by the sticking position and the convenience of operation. The strength of the clamp can only be determined by the clip itself. For the test piece that cannot be clamped or clamped unstable by the clamp due to the deep sticking position or too small area of ​​the sticking part, it is generally necessary to design a special pressure device. [0003] There may be the following pro...

AI Technical Summary

Problems solved by technology

[0003] There may be the following problems when attaching strain gauges to the existing terminals. First, the lowering position of the strain gauges is not accurate, resulting in a deviation in the pasting position, or when pressing the material, the pressure is directly applied to the narrow ring structure, which may easily cause the pasted strain gauges to be damaged. Slippage occurs and the correct pasting position is shifted, which affects the measurement sensitivity and accuracy; secondly, when pressing down, if the pressing force is too small, the strain gauge will not be firmly pasted, so that it will not It is easy to cause glue failure and affect the service life of the terminal. If the pressing force is too large, the strain gauge may be damaged
