Description

technical field [0001] The invention relates to a detection device for a capacitor. Background technique [0002] The capacitor detection device in the prior art is mainly realized by mechanical transmission. The main body of the device includes a horizontal turntable, an up and down moving detection electrode, a capacitance detection circuit, a turntable drive unit, and an electrode moving unit. In the process of capacitance detection, first judge whether there is a capacitor connected to the fixed electrode through the detection circuit connected to the fixed electrode. Only when the capacitor is detected on the fixed electrode, the detection electrode is controlled to move down and pressed together with the fixed electrode. The capacitor is connected to the terminal to measure the technical parameters and performance of the capacitor. During the assembly line operation of this kind of device, each detection fixture realizes 360-degree rotation with the horizontal turnta...

AI Technical Summary

Problems solved by technology

When the capacitance is continuously detected, because the rotation of the horizontal turntable adopts a mechanical transmission device, the wear is serious, resulting in a serious reduction in the repeat positioning accuracy; the upper and lower electrodes are in contact with the surface of the metal copper material, and the surface is easy to oxidize under the condition of high voltage and high current, resulting in Poor contact, sparks and discharges often occur during the measurement process

If there is a fixture failure on the horizontal turntable, the turntable will stop rotating, and the next fixture cannot be used to detect capacitance, which seriously reduces the detection efficiency

The mechanical transmission adopts a high-power motor, which has a complex structure and consumes a lot of energy

The control part of the device lacks an intelligent detection unit, the degree of automation is not high, the work efficiency is low, and the structure is relatively complicated
