Problems solved by technology
It takes a long time to heat the water during this process, and it is not easy to maintain a constant temperature. When the product is put into hot water, the inspection must be carried out after the aluminum shell of the product is heated, which wastes efficiency and energy.
Because the whole product must be put into hot water when doing the air tightness inspection, if there is a product with poor air tightness, it is easy to have water inhaled into the product, and the immersion of water is a fatal defect of the capacitor, and the product cannot be used again, resulting in damage to the product. waste

Embodiment Construction
[0009] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.
[0010] like figure 1 It shows a specific embodiment of an electrolytic capacitor sealing leak detection device of the present invention: it includes a sealer 1 and a matching upper cover 2, and a sealing ring is provided on the upper end surface of the sealer 1 in contact with the upper cover 2 3. An air pressure pump 5 is connected to the upper cover 2 through an air guide tube 4, and a pneumatic switch 6, an air pressure valve 7, a pressure regulating valve 8 and a pressure display gauge 9 are arranged in sequence between the sealer 1 and the air pressure pump 5.

Description
technical field [0001] The invention relates to a leak detection device, in particular to an electrolytic capacitor seal leak detection device and a detection method thereof. Background technique [0002] At present, during the manufacturing process of the bolt-type electrolytic capacitor seal, air leakage is likely to occur between the aluminum shell and the cover plate, the surface of the cover plate, and between the explosion-proof plug and the cover plate, and the sealing is mainly achieved by directly placing the capacitor Put it into the constant temperature hot water level, and then observe whether there are bubbles. This detection method can only detect the cover with poor sealing and the products with serious sealing and sealing, and because it is tested in hot water, it is very difficult It is difficult to distinguish whether it is the bubbles generated by the hot water itself or the bubbles caused by the unsealed seal of the product. It is easy to cause misjudgmen...
