Description

Technical Field

[0001] The present invention relates to the technical field of battery assembly, and in particular to a tool for assembling metal hydrogen batteries. Background Art

[0002] The metal hydrogen battery is a novel battery that utilizes a chemical reaction between metal and hydrogen to convert electrical energy into chemical energy. It utilizes thin sintered metal electrodes and hydrogen electrodes as key components, constructed by alternating stacks of these electrodes. During the charge and discharge process, a redox reaction occurs between the metal and hydrogen electrodes, enabling the directional movement of ions and electrons, generating an electric current. With its high energy density and excellent charge and discharge performance, this battery exhibits potential applications in aerospace, military, and other fields with specialized energy needs.

[0003] When assembling metal hydrogen batteries, thin sintered metal electrodes and hydrogen electrodes are generally stacked alternately through manual assembly. Due to the manual assembly, it is difficult to effectively test the stability of the stacking structure under the launch vibration environment after the battery assembly is completed. This will result in the battery having insufficient vibration resistance in the stacking structure during the actual launch process, resulting in the expansion of electrode microcracks and further deterioration of interlayer contact, which will cause the battery performance to decline or even fail to work normally, affecting the operational reliability and safety of the equipment using the battery. Summary of the Invention

[0010] Furthermore, the number of the limiting grooves is set to two, both of which are opened on the top of the support plate, and both of which are slidably connected to the bottom of the vibration plate.

[0026] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0027] Reference Figure 1-Figure 5 , this embodiment provides a tool for assembling a metal hydrogen battery, comprising a base 1, a vibration assembly is provided at the bottom of the base 1, a support plate 2 is provided at the bottom of the base 1, and a vibration plate 4 is provided on the top of the support plate 2;

[0028] The vibration assembly includes a driving unit and a limiting unit. The driving unit includes a motor 7 for driving the vibration plate 4 to vibrate. The limiting unit includes a limiting slot 6 for limiting the sliding of the vibration plate 4.

[0029] Reference Figure 1-Figure 5 Two sockets 3 are provided at the bottom of the base 1, and two plug-in plates 5 are provided on the top of the vibration plate 4. Each socket 3 is respectively plugged into the corresponding plug-in plate 5, and each socket 3 is respectively interference fit with the corresponding plug-in plate 5. The motor 7 is fixedly installed inside the support plate 2, and the output end of the motor 7 is fixedly connected to the disc 8. The top of the disc 8 is fixedly connected to the fixing column 9. A limiting hole 10 is provided inside the vibration plate 4, and the limiting hole 10 is slidably connected to the fixing column 9. The number of limiting grooves 6 is set to two, and the two limiting grooves 6 are both provided at the top of the support plate 2, and the two limiting grooves 6 are both slidably connected to the bottom of the vibration plate 4.

[0030] The vibration component can be used to apply random vibration to the metal hydrogen battery after it is packaged. The specific vibration method is that when it is necessary to verify the vibration resistance of the battery after assembly, the motor 7 is first started. The output end of the motor 7 drives the disc 8 to rotate, and the fixed column 9 on the top of the disc 8 rotates accordingly. Since the fixed column 9 is slidingly connected to the limiting hole 10 inside the vibration plate 4, the rotation of the fixed column 9 will cause the vibration plate 4 to move under the constraint of the limiting hole 10. At the same time, the two limiting grooves 6 opened at the bottom of the vibration plate 4 and the top of the support plate 2 are slidingly connected, which plays a limiting role, so that the vibration plate 4 can only move in a limited direction. Because the plug plate 5 on the top of the vibration plate 4 is interference fit with the socket 3 at the bottom of the base 1, the movement of the vibration plate 4 drives the base 1 to vibrate, thereby applying random vibration to the metal hydrogen battery placed on the base 1 after packaging.

[0031] The vibration component can simulate the vibration environment that the battery faces in actual use, especially in the launch phase, and discover potential problems in the battery stack structure in advance, such as whether the microcracks in electrode 11 will expand due to vibration, whether the interlayer contact will further deteriorate, etc. This will help to make timely improvements before the battery is put into use, improve the reliability and stability of the battery, reduce the risk of failure in actual operation, ensure the normal operation of the equipment using the battery, and at the same time reduce the economic losses and safety hazards caused by battery failure, and improve the overall quality of the metal hydrogen battery.

[0032] Reference Figure 1-Figure 5 An electrode 11 is provided on the top of the base 1, and the multiple electrodes 11 are arranged in a stacked manner. A plurality of external positioning rods 12 are provided on the top of the base 1, and the multiple external positioning rods 12 are respectively located on the outside of the multiple electrodes 11. A plurality of internal positioning rods 13 are provided on the top of the base 1, and the multiple internal positioning rods 13 are respectively located on the outside of the multiple electrodes 11. Diaphragm wings 14 are provided on both sides of each electrode 11, and a through hole is opened inside each diaphragm wing 14, which matches the inner positioning rod 13.

[0033] Through the cooperation of multiple external positioning rods 12, multiple internal positioning rods 13 and diaphragm wings 14, a positioning effect can be played during battery assembly, and the accuracy and consistency of battery assembly are improved. Multiple external positioning rods 12 are used to limit the battery from the outside to ensure that the entire stacking structure is accurately positioned in the horizontal direction and prevent the electrode 11 stack from offset. At the same time, the internal positioning rods 13 are closely matched with the through holes on the diaphragm wings 14 to further accurately position the battery and ensure that the relative position of each layer of electrode 11 and diaphragm is accurate. This precise positioning reduces the possibility of microcracks in the electrode 11, improves the interlayer contact effect, and improves the overall quality and reliability of the battery, thereby improving the service life and safety of the metal hydrogen battery.

[0034] Working principle: When it is necessary to verify the vibration resistance of the battery after assembly, first start the motor 7. The output end of the motor 7 drives the disc 8 to rotate, and the fixed column 9 on the top of the disc 8 rotates accordingly. Since the fixed column 9 is slidingly connected to the limiting hole 10 inside the vibration plate 4, the rotation of the fixed column 9 will cause the vibration plate 4 to move under the constraint of the limiting hole 10. At the same time, the two limiting grooves 6 opened at the bottom of the vibration plate 4 and the top of the support plate 2 are slidingly connected, which plays a limiting role, so that the vibration plate 4 can only move in a limited direction. Because the plug plate 5 on the top of the vibration plate 4 is interference fit with the socket 3 at the bottom of the base 1, the movement of the vibration plate 4 drives the base 1 to vibrate, thereby applying random vibration to the metal hydrogen battery placed on the base 1 and packaged.

[0035] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
