[0002] With the rapid development of new energy technologies, nickel-zinc batteries have been widely used in energy storage systems, power tools, and backup power supplies due to their advantages such as high energy density, environmental friendliness, and low cost. However, the sealing performance and safety of nickel-zinc batteries are key factors affecting battery quality during the production process. Poor battery sealing may lead to electrolyte leakage or internal gas escape, which may cause safety hazards or performance degradation. Therefore, it is essential to conduct strict sealing and safety tests on nickel-zinc batteries during the production process.

[0003] Traditional battery testing equipment may cause natural or internal liquid leakage during pressure testing of batteries. If leakage or smoke occurs during the test, it may not be handled in time, leading to pollution of the testing environment or even safety accidents.

[0004] Based on this, this utility model discloses a testing device for nickel-zinc battery production. Summary of the Invention

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Therefore, this utility model provides a testing device for nickel-zinc battery production. See [link to relevant documentation]. Figures 1 to 3 As shown, it includes a base 1, the upper part of which is connected to a sealing test box 2, the upper part of which is provided with a test component, and the inner cavity of which is provided with a protective component.

[0025] The detection assembly includes a drive cylinder 3. The outer shell of the drive cylinder 3 is fixedly connected to the upper part of the detection sealing box. A smoke sensor 32 is fixedly connected to the upper part of the inner cavity of the detection sealing box. The output shaft of the drive cylinder 3 passes through the sealed detection box 2. A detection head 31 is fixedly connected to the lower part of the output shaft of the drive cylinder 3. A fixing frame 33 is fixedly connected to the surface of the output shaft of the drive cylinder 3. A rack 34 is fixedly connected to both sides of the fixing frame 33. A threaded groove is opened in the inner cavity of each gear 35. A threaded rod 38 is threadedly connected to the inner cavity of each threaded groove. A piston 39 is provided on the opposite side of each threaded rod 38.

[0026] For details, see Figures 2 to 5 As shown, one end of the rack 34 is meshed with a gear 35. The base 1 has a groove at the position corresponding to the rack 34. Each gear 35 has a limiting groove on its opposite side. Each limiting groove has a plurality of rollers 36 inside. Each roller 36 has a positioning rod 37 movably connected to its opposite side. Each positioning rod 37 is fixedly connected to the inner wall of the sealing test box 2.

[0027] During operation, the nickel-zinc battery to be tested is placed inside the sealed testing chamber. The sealed chamber door 6 is closed to make the testing environment a closed state. The drive cylinder 3 is started, pushing the testing head 31 to press down on the battery, simulating external pressure to test the sealing and pressure resistance of the battery casing. The rack 34 of the drive cylinder 3 moves up and down with the output shaft, driving the meshing gear 35 to rotate.

[0028] The gear 35 drives the threaded rod 38 to move laterally through the internal threaded groove, pushing the piston 39 to apply balanced pressure to the side wall of the battery, further detecting the side of the battery. The roller 36 and the positioning rod 37 cooperate to ensure that the rack 34 moves smoothly.

[0029] Further, see Figures 1 to 6 As shown, the protective assembly includes multiple nozzles 4, each nozzle 4 is fixedly connected to the inner cavity of the base 1, each nozzle 4 penetrates the base 1, and the lower part of each nozzle 4 is connected to the same air pipe 41. One side of the air pipe 41 is connected to a vacuum pump 42, the upper part of the vacuum pump 42 is connected to an L-shaped pipe 43, one side of the L-shaped pipe 43 is connected to a gas tank 44, the inner cavity of the gas tank 44 is filled with inert gas, the other side of the sealing detection box 2 is fitted with an observation window 5, and the two sides of one end of the sealing detection box are respectively hinged with sealing box doors 6.

[0030] During operation, if the smoke sensor 32 detects an abnormality (such as electrolyte leakage or smoke), the air pump 42 drives the L-shaped pipe 43 to extract the inert gas inside the gas tank 44 and deliver it to the inside of the air pipe 41. The air pipe 41 then delivers the gas to the nozzle 4, and the nozzle 4 delivers the inert gas to the detection sealed box to suppress possible combustion reactions of the battery.

[0031] In summary, this effectively solves the problem that existing traditional battery testing devices may experience natural or internal liquid leakage during pressure testing of batteries. If leakage or smoke occurs during the test, it may not be handled in time, leading to pollution of the testing environment or even safety accidents.
