Description

Technical Field

[0001] This utility model relates to the field of capacitor technology, and in particular to a device for detecting the capacitance of a capacitor. Background Technology

[0002] The capacitor capacitance detection device is a key piece of equipment used in capacitor production and application to evaluate the electrical performance of capacitors. It obtains the capacitance parameters of the capacitor by establishing an electrical connection with the capacitor electrodes and applying a detection signal. This provides data support for capacitor quality grading, performance screening and fault diagnosis, and is an important link to ensure the stable operation of capacitors in circuits.

[0003] Existing equipment for capacitor capacitance testing typically includes a frame, a conveying assembly, a testing module, and a power unit. The conveying assembly, mounted on the frame, consists of multiple spaced-apart loading components used to carry and transport the capacitors to be tested. The testing module includes a testing plate and a capacitance sensor. The testing plate has conductive contacts corresponding to the capacitor electrodes, and the capacitance sensor is electrically connected to these contacts. The power unit uses a motor connected to the testing plate via a linkage structure. During operation, the conveying assembly transports the capacitors to the area below the testing plate. The motor, through the linkage structure, moves the testing plate downwards, causing the conductive contacts to engage with the capacitor electrodes. The capacitance sensor simultaneously collects capacitance data. After testing, the motor, through the linkage structure, moves the testing plate upwards to reset, and the conveying assembly transfers the tested capacitors to the next process.

[0004] In existing testing equipment, the transmission structure between the power unit and the testing plate is fixed, and the speed at which the power unit drives the testing plate and the number of times the testing plate is pressed during a single test cannot be adjusted. When dealing with capacitors of different models and capacitance ranges, the fixed testing speed cannot match the diverse testing needs, resulting in the inability to adjust the testing efficiency according to the actual production rhythm. At the same time, the fixed number of presses cannot adapt to the requirements of different capacitor electrode contact characteristics, which will affect the stability and consistency of capacitance test data. Utility Model Content
