Abstract

Disclosed is a durable electrolytic capacitor impregnation machine. The durable electrolytic capacitor impregnation machine comprises a rack, wherein an impregnation tank is arranged at the top of therack; the impregnation tank comprises a tank body and a cover body; a liquid storage cylinder is arranged outside the tank body; at least one through hole is formed in the upper portion and the lowerportion of the side surface of the tank body separately; each through hole in the upper portion of the side surface of the tank body is communicated with the upper portion of the liquid storage cylinder through a connecting pipe; each through hole in the lower portion of the side surface of the tank body is communicated with the lower portion of the liquid storage cylinder through a connecting pipe; the top of the liquid storage cylinder is provided with an opening and is correspondingly provided with a detachably connected cylinder cover; and a floating ball switch is arranged in the liquidstorage cylinder, and the top of the floating ball switch penetrates through the cylinder cover and is electrically connected with an external PLC controller. The electrolytic capacitor impregnation machine is high in durability and long in service life, so that the equipment use cost and the maintenance cost can be well lowered; and compared with the existing equipment, the durable electrolytic capacitor impregnation machine has outstanding improvement.

Description

Technical field [0001] The invention relates to the technical field of impregnation equipment, in particular to a durable electrolytic capacitor impregnation machine. Background technique [0002] The manufacturing process of aluminum electrolytic capacitors includes cutting, nailing, winding, impregnation, assembly, cleaning, casing, stringing, aging, testing, packaging and other processes. The impregnation process directly affects the performance and life of the capacitor. The operation is carried out in the impregnation machine. The existing impregnation machine generally includes a frame, an impregnation tank set on the frame, and a vacuum pipe, a vent pipe, a compressed air pipe, etc. connected to the impregnation tank, which can operate at normal pressure or high pressure, etc. Under the conditions, meet the impregnation process of aluminum electrolytic capacitors. During the high-pressure impregnation process, the capacitor is immersed in the electrolyte, and the negative...

AI Technical Summary

Problems solved by technology

During the high-pressure impregnation process, the capacitor is immersed in the electrolyte solution, and the negative pressure reaction force promotes the electrolyte solution to quickly enter the capacitor core and be absorbed by the electrolytic paper. During the impregnation process, the impregnation tank cannot be observed in real time because the impregnation tank is in a sealed state. Therefore, it is impossible to know whether the impregnation liquid is sufficient and whether the impregnation effect is ideal. Since the impregnated product needs to be deliquified in the tank, it is not suitable and there is no place to install a liquid level gauge in the impregnation tank. Most of the existing electrolytic capacitor manufacturers make improvements after purchasing impregnated tanks. The main point of improvement is the opening on the tank and welding and fixing the ordinary liquid level box. However, the size of the side opening of the liquid level box reaches 10cm×15cm. During the process, due to the internal pressure of the tank and the erosion of the impregnated medium, the contact between the liquid level box and the tank is prone to cracking and other damages, and due to the installation requirements of the liquid level box, the opening on the tank is relatively large, resulting in damage to the tank. The overall structural stability and compression resistance are reduced, which in turn affects the service life of the entire impregnation machine, which has caused great troubles to actual production for a long time, and the cost of production and maintenance is high. Therefore, the present invention aims to improve this
