[0015] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiments will be described clearly and completely in conjunction with the drawings in the embodiments below, however, the following specific embodiments and examples are only for the purpose of illustration, and are not limited to the present application.

[0016] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0017] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0018] To solve the above technical problems, such as Figures 1-3 As shown, this utility model designs a tool for testing the welding strength of current collectors in alkaline batteries, including a base 1, a support plate 2 on the base 1, a limiting plate 3 connected to the front side of the support plate 2, a T-shaped groove 4 formed between the limiting plate 3 and the support plate 2, the T-shaped groove 4 for inserting a current collector bottom cover 6, the limiting plate 3 also having a U-shaped limiting groove 5, a copper needle 7 welded to the current collector bottom cover 6 passing through the U-shaped limiting groove 5 from back to front, a protractor 11 on the front side of the limiting plate 3, the zero mark of the protractor 11 being parallel to the horizontal plane, and the ninety-degree mark of the protractor 11 being... When operating vertically downwards, first insert the collector cap 6 into the T-shaped slot 4 of the fixture, ensuring the copper needle 7 passes through the U-shaped limiting slot 5. Next, using the zero mark of the protractor 11 parallel to the horizontal plane as a reference, press the collector downwards, causing the copper needle 7 to contact the protractor 11 and measure its bending angle. If the bending angle of the copper needle 7 reaches or exceeds 45 degrees and the cap and copper needle 7 do not detach, the welding strength is considered qualified. If it does not reach 45 degrees or the cap and copper needle 7 detach, the welding strength is insufficient. The test results need to be recorded and fed back for adjustment of the welding process. Finally, clean and maintain the fixture to ensure its continuous and stable operation. Through this process, this device can quickly and accurately test the welding strength of the collector, improving the quality and efficiency of battery manufacturing.

[0019] Furthermore, the limiting plate 3 is provided with two bolt mounting holes 8, and the support plate 2 is provided with threaded holes corresponding to the bolt mounting holes 8. Bolts are installed in the bolt mounting holes 8, and the bolts are threadedly connected to the threaded holes on the support plate 2. The support plate 2 and the limiting plate 3 are detachably connected by bolts. The bolt connection allows for easy disassembly and installation between the limiting plate 3 and the support plate 2. This design not only facilitates maintenance and cleaning but also allows for quick replacement of components according to different testing needs, improving the flexibility of the inspection tool. The bolt connection provides stronger fixing force, ensuring a stable connection between the limiting plate 3 and the support plate 2 during the testing process, avoiding loosening due to vibration or external force, thereby improving the accuracy and reliability of the testing.

[0020] Furthermore, the bottom of the T-shaped slot 4 is provided with an arc-shaped support portion, which is used to support the electron collector cover 6, thereby better supporting the electron collector cover 6 and ensuring its stability during the testing process. This design can effectively reduce the displacement of the cover during the testing process and ensure the accuracy of the measurement results.

[0021] Considering that placing the collector cover 6 directly in the slot is not stable enough and may cause inaccurate measurements due to shaking, in order to solve this problem, such as Figure 4 As shown, the device further includes a clamping assembly, which includes clamping blocks 9 and elastic elements 10. The T-shaped slot 4 of the support block has grooves on its left and right sides, and the elastic elements 10 are installed in the grooves. The clamping blocks 9 are installed in the grooves and connected to the elastic elements 10. The two clamping blocks 9 are symmetrically arranged left and right and are used to clamp the collector cover 6, effectively clamping the collector cover 6 and providing a certain clamping force to ensure its fixation during the detection process. At the same time, the clamping force is relatively small and will not affect the removal operation. This design avoids measurement errors caused by loosening of the cover and improves the accuracy of the detection.

[0022] Furthermore, the elastic element 10 is a spring, which can provide a stable and adjustable clamping force to ensure that the collector cover 6 is always in a fixed state during the testing process, avoiding measurement errors caused by improper clamping.

[0023] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
