[0002] Tooling refers to the collective term for various tools used in the manufacturing process. It includes tools, fixtures, quick-release jigs, molds, measuring instruments, and workstation fixtures specifically designed and manufactured to achieve a particular technological purpose. They are typically designed to complete one or more specific technological actions. In the current lithium battery industry, to protect the safety of lithium batteries, a protective plate is often added to the outside of the battery to provide protection and simultaneously output the internal electrical energy. During the production process of the lithium battery protective plate…

[0003] To ensure the quality of lithium battery protection boards, it is often necessary to test them. During testing, multiple wires are usually connected. If the operator accidentally pulls on one of the wires, the lithium battery protection board may fall off the device. In this case, a testing fixture for lithium battery protection boards is needed to fix the lithium battery protection board to be tested.

[0004] During testing of lithium battery protection boards, dust may cover some component pins or test points on the protection board, affecting the good contact between the detection probe and the test point, reducing the accuracy of the test results. Moreover, dust is usually only discovered when testing is performed after the protection board is clamped. However, the clamping structure used for testing usually does not have a dust removal function, requiring additional dust removal equipment or removal of the protection board for cleaning before re-clamping and testing, which can easily reduce the overall efficiency of the test.

[0005] Therefore, those skilled in the art have provided a multifunctional lithium battery protection board testing fixture to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to provide a multifunctional lithium battery protection board testing fixture to solve the following technical problems:

[0007] How can we achieve dust removal while clamping and positioning the lithium battery protection board, so as to avoid dust covering the component pins or test points on the protection board and affecting the accuracy of test results?

[0008] The objective of this utility model can be achieved through the following technical solutions:

[0009] A multifunctional lithium battery protection board testing fixture includes a test platform, on which a positioning mechanism is connected. The positioning mechanism is used to fully clamp and fix the lithium battery protection board.

[0010] The positioning mechanism includes a clamping plate, with connecting frames fixedly connected to both ends of the clamping plate. The connecting frames pass through the test bench and are fixedly connected to a support shell. A lead screw is rotatably connected to the middle of the support shell below the test bench.

[0011] A fan is fixedly connected to the bottom of the support shell, and the clamping plate, connecting frame and support shell are interconnected.

[0012] Furthermore, the fan is arranged on both sides below the support shell, the output end of the fan is connected to the support shell, the clamping plate and the connecting frame are both provided with cavities, and the inner side of the clamping plate is provided with an inclined downward opening, which is connected to the cavity.

[0013] Furthermore, an anti-slip pad is fixedly connected below the clamping plate. The anti-slip pad is made of rubber. A flexible pad is fixedly connected to the test platform. During testing, the lithium battery protection board is placed on the flexible pad.

[0014] Furthermore, a threaded sleeve is fixedly connected to the middle of the support shell, and the threaded sleeve is slidably connected to the outside of the lead screw.

[0015] Furthermore, a dustproof net is fixedly connected to the opening of the clamping plate, and a ventilation mesh plate is fixedly connected to the inner side of the dustproof net, with the mesh holes of the ventilation mesh plate inclined downwards.

[0016] Furthermore, a support frame is fixedly connected to the bottom of the test bench, a support plate is fixedly connected below the support frame, a drive motor is fixedly connected to the support plate, and the output end of the drive motor is fixedly connected to the lead screw.

[0017] Furthermore, the clamping plate is arranged in a rectangular frame shape, and the connecting frame is arranged in a bent shape.

[0018] Furthermore, the test platform is provided with a guide opening, which is used to guide and limit the connection frame.

[0019] The beneficial effects of this utility model are:

[0020] (1) This utility model is provided with a clamping plate, a connecting frame, and a support shell. The clamping plate is set in a rectangular frame shape. When positioning the protective plate, the drive motor drives the lead screw to rotate, thereby driving the support shell and the connecting frame and clamping plate fixed to it to move down synchronously, so as to clamp and fix the protective plate in a comprehensive and fast manner.

[0021] (2) This utility model is provided with a clamping plate, a connecting frame, a support shell, and a fan. The clamping plate has an inclined downward opening on its inner side. The clamping plate, the connecting frame, and the support shell are interconnected. Before clamping the protective plate, the clamping plate and the protective plate maintain a certain distance. At this time, the fan blows air onto the surface of the protective plate through the opening of the clamping plate, which effectively prevents dust from covering the component pins or test points of the protective plate and affecting the good contact between the detection probe and the test point, thus ensuring the accuracy of the test results.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see the appendix Figure 1-5A multifunctional lithium battery protection board testing fixture in this embodiment of the present invention includes a test bench 1, on which a positioning mechanism 2 is connected. The positioning mechanism 2 is used to fully clamp and fix the lithium battery protection board. During testing, the operator holds a test probe to test the lithium battery protection board, or tests it through external testing equipment.

[0032] The positioning mechanism 2 includes a clamping plate 21, which is arranged in a rectangular frame shape and can clamp and position the lithium battery protection board in all directions. The two ends of the clamping plate 21 are fixedly connected to the connecting frame 22, which passes through the test bench 1 and is fixedly connected to the support shell 28. The test bench 1 is rotatably connected to the middle of the support shell 28, and the lead screw 24 is used to drive the clamping plate 21 to move.

[0033] A fan 23 is fixedly connected to the bottom of the support shell 28. In this design, two fans 23 are set up, located on both sides below the support shell 28, to ensure the stability of the airflow distribution. This allows the openings on each side of the clamping plate 21 to discharge air and remove dust relatively evenly. The clamping plate 21, the connecting frame 22, and the support shell 28 are interconnected. During the clamping process, the support shell 28, the connecting frame 22, and the clamping plate 21 can cooperate to clamp and position the lithium battery protection board. On the other hand, during the clamping process, they can work with the fans 23 to automatically remove dust from the surface of the lithium battery protection board, avoiding dust interference with the test and thus improving the accuracy of the test. There is no need to configure additional dust removal equipment to clean the surface, or to remove the board for cleaning and then re-clamp and test, which can prevent the impact on the overall efficiency of the test.

[0034] The fan 23 is located on both sides below the support shell 28. When the lead screw 24 drives the support shell 28 to move upward, it will not affect the space required for the fan 23. At the same time, the fan 23 is located below the support shell 28, which can avoid dust from above to a certain extent, prevent excessive dust accumulation at the air inlet of the fan 23, and facilitate the maintenance and repair of the fan 23. The output end of the fan 23 is connected to the support shell 28. The clamping plate 21 and the connecting frame 22 are both provided with cavities 7. The inner side of the clamping plate 21 has an inclined downward opening. The inclined downward opening can not only guide the airflow, but also prevent external dust from accumulating on its surface. The opening is connected to the cavity 7. The air inlet of the fan 23 is provided with a filter screen. The fan 23 draws in the filtered air and discharges it sequentially into the support shell 28, the connecting frame 22, and the clamping plate 21, and finally discharges it outward through the opening of the clamping plate 21 to clean the surface of the lithium battery protection board.

[0035] An anti-slip pad 26 is fixedly connected to the bottom of the clamping plate 21. The anti-slip pad 26 is made of rubber. A flexible pad 3 is fixedly connected to the test table 1. During the test, the lithium battery protection board is placed on the flexible pad 3 to avoid accidentally damaging the lithium battery protection board during clamping.

[0036] A threaded sleeve 29 is fixedly connected to the middle of the support shell 28. The threaded sleeve 29 is slidably connected to the outside of the lead screw 24. A support frame 4 is fixedly connected to the bottom of the test bench 1. A support plate 5 is fixedly connected below the support frame 4. A drive motor 25 is fixedly connected to the support plate 5. The output end of the drive motor 25 is fixedly connected to the lead screw 24. During the clamping process, the drive motor 25 drives the lead screw 24 to rotate. The threaded sleeve 29 engages with the lead screw 24 and slides on its outside, thereby driving the support shell 28, the connecting frame 22 and the clamping plate 21 to move synchronously to clamp and fix them.

[0037] A dustproof net 27 is fixedly connected to the opening of the clamping plate 21. A ventilation mesh plate 6 is fixedly connected to the inner side of the dustproof net 27. The mesh holes of the ventilation mesh plate 6 are set at an angle downward. During dust removal, the multiple mesh holes of the ventilation mesh plate 6 can promote the uniform distribution of airflow, making it easier to remove dust from the lithium battery protection board more evenly. The dustproof net 27 can prevent external dust from entering the cavity 7.

[0038] The connecting frame 22 is bent, and the test bench 1 has a guide opening 8. The guide opening 8 is used to guide and limit the connecting frame 22. The upper end of the connecting frame 22 is slidably connected to the test bench 1 through the guide opening 8. The bent shape can prevent the connecting frame 22 from moving too high, increase the time when the clamping plate 21 positions the lithium battery protection board, and guide the airflow direction.

[0039] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
