Abstract
Description
Technical Field
[0001] The utility model relates to a detection tool, in particular to a bare battery core detection tool. Background Art
[0002] Winding is a key process in the production of lithium batteries. It is generally the process of winding materials such as positive and negative electrodes, separators, positive and negative tabs, protective tapes, and termination tapes into bare cells through winding equipment. The wound bare cells are relatively fragile and need to undergo a series of inspections and tests. During the test process, the bare cells will be damaged if there is any carelessness, such as causing scratches on the surface of the cells, decarbonization, etc., which will lead to the scrapping of the cells. In order to improve the inspection efficiency and protect the bare cells, a bare cell inspection fixture is designed to solve the above problems. Utility Model Content
[0003] In view of the deficiencies in the existing technology, the purpose of the present invention is to provide a bare cell detection tooling that can effectively protect the bare cells, improve detection efficiency, and has strong practicality.
[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions: a bare battery cell detection tooling, including a battery cell fixing frame and a Teflon pressing clamp, the Teflon pressing clamp is placed in the battery cell fixing frame, the battery cell fixing frame includes a bakelite fixing frame, a fixing bracket and Teflon, a fixing bracket is arranged in the middle of the bakelite fixing frame, the battery cell fixing position is between the battery cell fixing frame and the fixing bracket, and Teflon is affixed to both sides of the fixing bracket.
[0005] Preferably, the Teflon pressing fixture includes a surface support frame, a pressure plate, a connecting rod, a Teflon fixing plate and a sticky transparent adhesive block. The surface support frame cooperates with the fixing bracket, and the surface support frame is connected to the Teflon fixing plate through a connecting rod. The connecting rod is set through the surface support frame, and the lower part of the surface support frame fixes the Teflon on the Teflon fixing plate through a sticky transparent adhesive block.
[0006] The beneficial effects of the utility model are as follows: the structure of the utility model is reasonably designed, the Teflon can be easily replaced to prevent the Teflon from failing and wearing out the battery core, the detection efficiency is improved, and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0012] Reference Figs. 1-3 This specific embodiment adopts the following technical solution: a bare battery cell detection tooling, including a battery cell fixing frame 1 and a Teflon pressing fixture 2, the Teflon pressing fixture 2 is placed in the battery cell fixing frame 1, the battery cell fixing frame 1 includes a bakelite fixing frame 11, a fixing bracket 12 and Teflon 13, a fixing bracket 12 is provided in the middle of the bakelite fixing frame 11, the battery cell fixing position is between the battery cell fixing frame 11 and the fixing bracket 12, and Teflon 13 is attached to both sides of the fixing bracket 12.
[0013] It is worth noting that the Teflon pressing fixture 2 includes a surface support frame 21, a pressure plate 22, a connecting rod 23, a Teflon fixing plate 24 and a sticky transparent adhesive block 25. The surface support frame 21 cooperates with the fixing bracket 12. The surface support frame 21 is connected to the Teflon fixing plate 24 through the connecting rod 23. The connecting rod 23 is set through the surface support frame 21. The lower part of the surface support frame 21 fixes the Teflon 13 on the Teflon fixing plate 24 through the sticky transparent adhesive block 25.
[0014] In this specific embodiment, the cell retaining frame is made of Bakelite and features a dual-cell design, allowing for testing of two cells simultaneously. To prevent cosmetic defects such as decarburization and wear during testing, a Teflon protective film is applied to the inside of the retaining frame. The Teflon film must be replaced after each test to prevent wear and tear on the cells. The Teflon pressing fixture, made of aluminum, is lightweight and portable, and its primary function is to quickly attach the Teflon film to the inside of the positioning frame.
[0015] The method of using this specific embodiment is as follows: fix the smooth surface of Teflon with a thickness of 0.05mm on the fixing plate of the pressing fixture with a transparent adhesive block, then place the pressing fixture in the battery cell fixing frame, and press the pressing plate by hand to make the Teflon fit tightly against the inner side of the bracket (the single-sided adhesive on the back of Teflon is sticky).
[0016] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
