Description

Technical Field

[0001] This utility model relates to the field of battery testing fixture technology, specifically a clamping device for testing solid-state batteries. Background Technology

[0002] Solid-state batteries are a battery technology that uses a solid electrolyte to replace the liquid electrolyte in traditional lithium-ion batteries. To ensure that solid-state battery products meet product requirements and guarantee consistent product quality and performance, testing is necessary.

[0003] A Chinese patent (CN222189342U) discloses a clamping device for testing solid-state batteries, including a base plate, a clamping mechanism on the base plate, an electric push rod at the rear end of the upper surface of the base plate, a clamping platform at the output end of the electric push rod, a solid-state battery placed on the upper surface of the clamping platform, and rollers at the four corners of the lower surface of the clamping platform, the rollers contacting the upper surface of the base plate. In this invention, when using the clamping device, the clamping platform is first pushed out by the electric push rod, the solid-state battery is placed on the surface of the clamping platform, the electric push rod retracts, and then the clamping mechanism clamps the solid-state battery, facilitating testing. In this solution, the process of placing the solid-state battery will not collide with other components, avoiding damage to the solid-state battery due to impact.

[0004] When testing solid-state batteries, the testing of the positive and negative electrodes is crucial. To obtain comprehensive and accurate test data, it is necessary to flip the positive and negative electrodes of the fixed solid-state battery. However, current clamping devices used for solid-state battery testing generally lack the capability to automatically flip the positive and negative electrodes. In actual testing, manual flipping of the battery is often necessary, significantly reducing testing efficiency. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a clamping device for solid-state battery testing, including: a clamping worktable 1, a clamping cylinder 12, bearing seats 10 on both sides of the top of the clamping worktable 1, a main shaft 9 rotatably mounted inside the bearing seats 10, the bearing seats 10 provide stable support for the main shaft 9, ensuring the stability of the main shaft 9 during rotation, reducing the impact of shaking on the accuracy of clamping and flipping, and laying the foundation for accurate testing of solid-state batteries.

[0022] A gear 15 is fixed to one end of the main spindle 9, and a rack 7 is slidably mounted on one side of the top of the clamping table 1. The gear 15, as a transmission component, converts the translational motion of the rack 7 into the rotational motion of the main spindle 9 through its interaction with the rack 7, achieving a conversion from linear motion to rotational motion and providing a power transmission mechanism for the flipping of the solid-state battery. A push cylinder 4 is mounted on one side of the top of the clamping table 1, with one end connected to one end of the rack 7. The top of the rack 7 has teeth that mesh with the gear 15. The push cylinder 4 provides power for the translation of the rack 7. By controlling the extension and retraction of the push cylinder 4, the moving distance and speed of the rack 7 can be precisely controlled, thereby achieving precise control of the rotation angle of the main spindle 9. This facilitates the flipping of the positive and negative terminals of the solid-state battery, improving testing efficiency. The meshing of the teeth on the top of the rack 7 with the gear 15 ensures stability and accuracy during transmission, reduces energy loss and errors during transmission, and allows the main spindle 9 to rotate at a predetermined angle, ensuring the reliability of the solid-state battery flipping. A clamping cylinder 12 is fixed to the outer wall of the middle section of the main shaft 9. Clamping plates 13 are provided at the ends of the two piston rods of the clamping cylinder 12. The clamping cylinder 12 clamps and fixes the solid-state battery through the clamping plates 13, ensuring the stability of the solid-state battery during testing and preventing the accuracy of test results from being affected by battery shaking. Simultaneously, the clamping cylinder 12, fixed to the main shaft 9, can rotate with the main shaft 9, enabling the solid-state battery to be flipped.

[0023] The clamping worktable 1 has motorized turntables 2 on both sides, and the top of the motorized turntables 2 has positioning slots 3. After the solid-state battery completes testing at the current station, the rotation function of the motorized turntables 2 can quickly and accurately transport the battery to the next station without manual handling or the use of other complex conveying equipment. This greatly shortens the transfer time of the battery between different stations, improves the efficiency of the entire testing process, and accelerates the research and development and production progress of solid-state batteries.

[0024] The horizontal thrust cylinder 4 and the rack 7 are arranged in parallel. One end of the piston rod of the horizontal thrust cylinder 4 is provided with a connecting plate 5, and a connecting rod 6 is provided between the connecting plate 5 and one end of the rack 7. The connecting plate 5 and the connecting rod 6 serve to connect the horizontal thrust cylinder 4 and the rack 7, so that the extension and retraction movement of the horizontal thrust cylinder 4 can be accurately transmitted to the rack 7. At the same time, this connection method is simple, reliable, and easy to install and maintain.

[0025] A fixed base 11 is fixed to the outer wall of the main shaft 9, and one side of the outer wall of the clamping cylinder 12 is fixed to the fixed base 11. The fixed base 11 provides a stable installation position for the clamping cylinder 12, ensuring that the connection between the clamping cylinder 12 and the main shaft 9 is firm and reliable, preventing the clamping cylinder 12 from loosening or shifting during the flipping process, and ensuring the stability of the solid-state battery clamping and flipping.

[0026] A protective cover 14 is provided on the top of the clamping worktable 1, outside the gear 15 and rack 7. The protective cover 14 can prevent foreign objects from entering the transmission parts of the gear 15 and rack 7, reduce transmission failure and wear caused by foreign objects, extend the service life of the device, and also improve the safety of operation.

[0027] A slide rail 8 is provided on the top of the clamping worktable 1 below the rack 7, allowing the rack 7 to slide above the slide rail 8. The slide rail 8 provides guidance for the sliding of the rack 7, ensuring that the rack 7 maintains linear motion during translation, reducing transmission errors and jamming caused by offset, improving the smoothness and accuracy of the rack 7's sliding, and thus ensuring the accuracy of solid-state battery flipping.

[0028] When using the clamping device for solid-state battery testing, the solid-state battery is clamped and fixed by the clamping plate 13 of the clamping cylinder 12, with the positive terminal of the solid-state battery facing upwards. At this time, the positive terminal of the solid-state battery can be tested. When the negative terminal needs to be tested, the connecting plate 5 and the connecting rod 6 are moved by the horizontal push cylinder 4, which in turn drives the rack 7 to move horizontally under the guidance of the slide rail 8. Through the cooperation of the rack 7 and the gear 15, the gear 15 is rotated, which drives the main shaft 9 to rotate, realizing the flipping of the clamping cylinder 12 and the solid-state battery. By controlling the extension and retraction stroke of the horizontal push cylinder 4, the rotation angle of the main shaft 9 is controlled, which facilitates the flipping of the positive and negative terminals during solid-state battery testing and improves testing efficiency.

[0029] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
