Description

Technical Field

[0001] This utility model relates to the technical field of fixing fixtures for lithium battery testing, specifically to a tooling fixture for lithium battery testing equipment. Background Technology

[0002] Lithium batteries are devices used to store electricity and also serve as power supply devices. Many electronic products now incorporate batteries, which eliminate the need for prolonged connection to a power source, thus improving the portability of electronic devices. Therefore, lithium batteries have high quality requirements and undergo various tests after production to ensure their safety performance meets standards.

[0003] To ensure the smooth conduct of the test, the battery needs to be clamped and positioned to ensure its stability, especially for the nail penetration test, which requires the use of a standard testing needle inserted into the battery. If the battery is unstable, it will directly affect the accuracy of the nail penetration test.

[0004] Current clamping devices are simply two plates. However, because needle puncture applies pressure to the battery, this pressure can affect the battery's stability. Existing clamping devices do not have a solution for this, which means that the battery will be pushed downwards under needle pressure, affecting the puncture. Therefore, a tooling fixture for lithium battery testing equipment is proposed. Utility Model Content

[0005] The technical solution adopted by this utility model to solve the technical problem is: a tooling fixture for lithium battery testing equipment, including a base plate, an anti-slip pad fixedly connected to the bottom side wall of the base plate, an adjustment groove opened in the middle of the top side wall of the base plate, a spacer plate fixedly connected in the middle of the adjustment groove, sliders slidably connected to both ends of the adjustment groove, a vertical plate detachably connected to the top side wall of each slider, a movable groove opened in the middle of one side wall of the vertical plate, an extension plate provided on one side of the movable groove, and a push plate fixedly connected to one end of the extension plate, the push plate having an arc-shaped structure.

[0006] As a preferred embodiment of this utility model, springs are fixedly connected to the two side walls of the partition plate that are far apart from each other. The springs are fixedly connected to one side wall of the slider through one end that is far away from the partition plate. Side grooves are opened on the two opposite side walls of the adjustment groove. A positioning block is slidably connected in the side groove. The positioning block is fixedly connected to one side wall of the slider through one end.

[0007] As a preferred technical solution of this utility model, a miniature electric telescopic rod is detachably embedded in the bottom side wall of the movable groove, and a linkage block is slidably connected in the movable groove. The linkage block is detachably connected to the output end of the miniature electric telescopic rod through the bottom side wall. The extension plate has an upwardly inclined structure, and the extension plate is detachably connected to the side wall of the linkage block through the end away from the push plate.

[0008] As a preferred technical solution of this utility model, a connecting column is detachably embedded in the middle of the top side wall of the vertical plate, a clamping plate is detachably connected to one end of the side wall of the connecting column, and an electrode plate is embedded in the middle of the side of the clamping plate away from the connecting column.

[0009] As a preferred embodiment of this utility model, a rubber insulating pad is fixedly connected to the side wall of the clamp away from the connecting post. The rubber insulating pad has a ring structure, and the electrode plate is located in the middle of the rubber insulating pad. A through hole is opened in the middle of the connecting post, and an electric wire is inserted and connected in the through hole. The electrode plate is connected to the electric wire.

[0010] The present invention has the following advantages: an extension plate is provided on one side of the vertical plate, and a push plate is fixed at one end of the extension plate. In this way, the bottom of the battery can be lifted by the push plate to help stabilize the battery and prevent the battery from moving downward under the pressure of the needle. The lifting by the push plate ensures that the battery will not be displaced during the testing process, thereby ensuring that the testing needle can be smoothly inserted into the battery at the designated position and ensuring the reliability of the testing data.

[0011] The push plate can be raised and lowered by a miniature electric telescopic rod, which can accommodate batteries of different sizes and provide stable support for batteries of different sizes, thereby improving the flexibility of equipment application. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3 This utility model discloses a tooling fixture for a lithium battery testing equipment, including a base plate 1. An anti-slip pad 10 is fixedly connected to the bottom side wall of the base plate 1. An adjustment groove 2 is opened in the middle of the top side wall of the base plate 1. A partition plate 3 is fixedly connected in the middle of the adjustment groove 2. A slider 4 is slidably connected to both ends of the adjustment groove 2. A vertical plate 5 is detachably connected to the top side wall of each slider 4. A movable groove 11 is opened in the middle of one side wall of the vertical plate 5. An extension plate 12 is provided on one side of the movable groove 11. A push plate 13 is fixedly connected to one end of the extension plate 12. The push plate 13 has an arc-shaped structure.

[0018] Springs 14 are fixedly connected to the two side walls of the partition plate 3 that are far apart from each other. The springs 14 are fixedly connected to the side wall of the slider 4 through the end of the springs 14 that is far away from the partition plate 3. Side grooves 15 are opened on the two opposite side walls of the adjustment groove 2. Positioning blocks 16 are slidably connected in the side grooves 15. Positioning blocks 16 are fixedly connected to the side wall of the slider 4 through one end. A miniature electric telescopic rod 18 is detachably embedded in the bottom side wall of the movable groove 11. A linkage block 17 is slidably connected in the movable groove 11. The linkage block 17 is detachably connected to the output end of the miniature electric telescopic rod 18 through the bottom side wall. The extension plate 12 has an upward inclined structure. The extension plate 12 is detachably connected to the side wall of the linkage block 17 through the end of the extension plate 12 that is far away from the push plate 13.

[0019] The technical effects of this solution are as follows: the battery is clamped between two clamping plates 8, and then the micro electric telescopic rod 18 is activated to drive the linkage block 17 to rise, thereby driving the extension plate 12 and the push plate 13 to rise synchronously. The push plate 13 is then fitted onto the bottom side wall of the battery, thereby achieving a lifting effect on the battery and ensuring its stability. The obliquely set extension plate 12 can provide stable support for the battery, ensuring that the battery will not move downward under the pressure of the needle penetration, ensuring the smooth conduct of the needle penetration test, and avoiding the problem of inaccurate experimental data due to battery displacement under pressure. Furthermore, the lifting and lowering of the push plate 13 can lift batteries of different sizes, increasing the flexibility of equipment application.

[0020] A connecting post 6 is detachably embedded in the middle of the top side wall of the vertical plate 5. A clamping plate 8 is detachably connected to one end of the side wall of the connecting post 6. An electrode plate 9 is embedded in the middle of the side of the clamping plate 8 away from the connecting post 6. A rubber insulating pad 19 is fixedly connected to the side wall of the clamping plate 8 away from the connecting post 6. The rubber insulating pad 19 has a ring structure, and the electrode plate 9 is located in the middle of the rubber insulating pad 19. An insertion hole 7 is opened through the middle of the connecting post 6, and an electric wire is inserted into the insertion hole 7. The electrode plate 9 is connected to the electric wire.

[0021] The technical benefits of this solution are as follows: connecting electrode plates 9 to one side of the clamping plate 8 allows the electrode plates 9 to be connected to wires. When clamped, the electrode plates 9 will adhere to the positive and negative terminals of the battery, thus enabling monitoring of the voltage performance inside the battery after puncture and determining the stability of the battery voltage after puncture. At the same time, the rubber insulating pad 19 can prevent leakage from affecting the safety of the staff, and it can increase the friction of clamping and improve the stability of clamping.

[0022] Specifically, in use, the two vertical plates 5 are pushed outwards, and the battery is placed between the two clamping plates 8. Then, the vertical plates 5 are released so that the two clamping plates 8 move closer to the center under the action of the spring 14, thereby clamping the battery. As needed, the spring 14 can be a relatively stiff structure to ensure the stability of the clamping and to ensure that the electrode plate 9 is in contact with the positive and negative terminals of the battery after clamping. The rubber insulating pad 19 connected to the clamping plate 8 can prevent leakage and injury to the staff, and at the same time increase the friction to improve the reliability of the clamping. After the battery is clamped, the micro electric telescopic rod 18 is activated to drive the push plate 13 to rise and fall, and the push plate 13 is clamped on the bottom of the battery to push the battery, ensuring that the battery remains unchanged under the pressure of the needle, thereby ensuring the smooth conduct of the needle penetration experiment and ensuring the reliability of the test data.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
