An automatic clamping device for a capacitance detection system

Abstract

The invention provides an automatic clamping device of a capacitance detection system, and relates to the field of detection. The device comprises a base, an adjusting block, telescopic rods, and a linkage mechanism. An adjusting groove with an upward opening is formed in the inner part of the base. An adjusting mechanism is arranged at the left side of the outer portion of the adjusting groove. An inner cavity is arranged in the adjusting block, and the top of the inner cavity communicates with the outside through an insertion hole. The linkage mechanism is located at the bottom of the innercavity, and is in sliding connection with a side wall of the inner cavity. The telescopic rods are symmetrically arranged at two ends of the linkage mechanism. One end of each telescopic rod is hingedto the linkage mechanism, and the other end of each telescopic rod is hinged to the clamping mechanism. The clamping mechanism is located in a position close to the insertion hole of the inner cavity, and is fixedly connected with the side wall of the inner cavity. The device is easy to operate, and measurement staffs do not need to fix and loosen capacitance pins by hand, thereby improving the measurement efficiency, and avoiding measurement errors generated after contact with the capacitive pins by human hands.

Description

technical field [0001] The invention belongs to the detection field, and in particular relates to an automatic clamping device of a capacitance detection system. Background technique [0002] During the production process of capacitors, the quality personnel of the production line generally check the capacitance value parameters of the capacitors at a certain frequency to extract the capacitance value parameters for making CPK. In addition, after the capacitors have been cooled by high-temperature tests, they also need to measure their capacitance values. Judging whether the capacitor has passed the high temperature test and whether the capacitance value of the capacitor is stable is an important parameter for judging whether the production quality of the production line varies. [0003] In the prior art, when measuring the capacitance value of the batch capacitor, the measuring personnel generally fix the pin of the capacitor with the input end of the measuring instrument b...

Problems solved by technology

[0003] In the prior art, when measuring the capacitance value of the bulk capacitor, the measuring personnel usually fix the pin of the capacitor with the input terminal of the measuring instrument by hand, and then measure. This method needs to be fixed by hand continuously, and then Loosening it by hand is time-consuming and labor-intensive, and the efficiency is not high. In addition, human hands generally have static electricity and pollutants. After contacting the capacitor pins, measurement errors are prone to occur.
