Description

Technical Field

[0002] Battery refers to a cup, trough or other container or part of a composite container that contains electrolyte solution and metal electrodes to generate electric current. It is a device that can convert chemical energy into electrical energy. It has positive and negative electrodes. Batteries generally refer to small devices that can generate electrical energy. With the advancement of technology, there are many types of batteries at present, and among them, lithium manganese needle batteries are also called float batteries, night fishing glow stick batteries, firecracker batteries, electronic fish float batteries, needle batteries, etc., and such batteries need to have their external shell strength tested during the production process.

[0003] According to the search, the Chinese patent with patent number CN219121920U discloses a lithium manganese syringe battery shell strength testing instrument, including a testing frame, the inner wall surface of the testing frame is provided with a slide groove, the interior of the testing frame is slidably connected to a mobile platform through the slide groove, a top frame is arranged on the top side of the testing frame, both sides of the bottom end of the top frame are fixedly connected to a lower pressure frame, and the top of the sensor support is fixedly connected to a pressure sensor; when the utility model is testing, the mobile platform moves to one side of the testing frame to load the material, and multiple syringe batteries are supported by the placement groove, the mobile platform is reset, and at the same time, the lifting motor drives the testing platform to rise, and the two ends of the syringe battery are pressed into the lower pressure head and continue to rise. The two ends of the syringe battery are subjected to force, and at the same time, the pressure sensor performs pressure sensing detection. When the specified test pressure is reached and there is no obvious deformation at the two ends of the syringe battery, the test is qualified. The whole process is convenient and efficient, and the strength of the two ends of the syringe battery can be quickly measured.

[0004] Regarding the above-mentioned related technologies, the applicant believes that although the above-mentioned testing instrument can test the strength of the syringe-type battery casing, during the battery testing process, the two ends of the battery are easily in an uneven state, which will affect the test value and the test accuracy. Manually arranging the syringe battery is difficult to ensure the flatness, and it is not convenient for the staff to operate frequently, which affects the overall detection efficiency. For this reason, we propose a battery casing strength testing device. Utility Model Content

The testing module 200 includes a lifting component 210 arranged on the top of the support frame 120. The lifting component 210 is connected to the top of the main frame 110. A plurality of elastic force testing components 220 are arranged on the lifting component 210. Arrangement components 230 are arranged on both sides of the top of the main frame 110. The two arrangement components 230 are connected to the lifting component 210. Translation grooves 240 are opened on both sides of the inner wall of the main frame 110. A placement component 250 is slidably connected between the inner walls of the two translation grooves 240.

[0038] During use, the syringe battery that needs to be tested is located on the placement component 250 and below the lifting component 210. The subsequent lifting component 210 is lifted first, thereby pulling the two sorting components 230 close to each other. When the two sorting components 230 are close to each other, the syringe battery will be sorted so that the two ends of the syringe battery are in a flush state. The subsequent lifting component 210 drives the two sorting components 230 away and drives multiple sorting components 230 to descend at the same time.
