[0002] The airtightness testing machine, also known as the airtightness testing machine, is a device widely used for airtightness testing of various seals such as faucet cavities, automobile cylinders, piston cavities, elbow cavities, pressure gauges, gas tanks, etc. It is also used for airtightness testing of batteries after sealing.

[0003] As electronic products become more and more sophisticated, batteries, as power storage devices, need to be paid more attention in the production process. In order to ensure the quality of batteries, it is necessary to test the air tightness of batteries. However, most of the existing air tightness detection devices still rely on manual operation, resulting in low detection efficiency, and the batteries tested are prone to leaks. At the same time, the battery products after detection need to be manually sorted from qualified products to defective products. Due to long-term manual operation, the workers' concentration decreases, so the negligence of the workers may cause defective products to be mixed with qualified products, which not only prolongs the workers' working time, but also reduces the efficiency of battery detection.

[0004] According to the publication number: CN214748698U, a new type of fully automatic airtightness detection machine is proposed, including: a bottom box, a bottom plate, an upper shell, an airtightness tester, a pneumatic pressurizing mechanism, a product placement bottom mold, an upper mold pressurizing seat, an upper mold air inlet pressure regulating valve and a controller; the upper shell is arranged above the bottom box, the upper shell has a cavity for accommodating the product placement bottom mold, the bottom plate is arranged on the upper side of the bottom box, the product placement bottom mold is arranged on the bottom plate, and the pneumatic pressurizing mechanism includes a transmission assembly and an air intake system; the transmission assembly is installed on the upper shell, the upper mold pressurizing seat is connected to the transmission assembly for transmission, and the transmission assembly is used to drive the upper mold pressurizing seat to move away from and close to the product placement bottom mold; the air intake system is connected to the upper mold pressurizing seat, the upper mold air inlet pressure regulating valve is installed on the upper mold pressurizing seat, and the airtightness tester is connected to the upper mold air inlet pressure regulating valve, which is used to control the upper mold air inlet pressure regulating valve to adjust the air pressure; the airtightness tester and the pneumatic pressurizing mechanism are both connected to the controller.

[0005] According to the above introduction, most of the airtightness detection devices still rely on manual operation, resulting in low detection efficiency, and the detected batteries are prone to leakage. At the same time, the battery products after detection still need to be manually sorted into qualified products and defective products, which not only prolongs the workers' working time, but also reduces the efficiency of battery detection. In order to solve the above problems, we have proposed a fully automatic airtightness detection machine. Utility Model Content
