Description

Technical Field

[0002] In the production process of lithium-ion batteries, the uniform wetting of the electrolyte and the removal of air bubbles are key factors affecting battery performance and consistency. This process directly determines the battery's electrochemical performance, cycle life, and safety. Therefore, it is necessary to use a shaking device to shake the lithium-ion battery.

[0003] Existing oscillation devices cannot adjust the oscillation amplitude and frequency, making it difficult to meet the oscillation requirements of lithium-ion batteries of different specifications. This results in insufficient electrolyte wetting inside the lithium-ion battery or damage to the lithium-ion battery. Therefore, this application proposes an oscillation device for lithium-ion batteries. Utility Model Content

Detailed Implementation

[0039] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figure 1-6 This utility model provides a vibration device for lithium-ion batteries, including a mounting body 1;

[0041] The fixing component 2 is slidably disposed on the inner side of the mounting body 1;

[0042] The jacking mechanism 3, located inside the mounting body 1, includes a hydraulic rod 33 located inside the mounting body 1; a driven synchronous pulley 34 rotatably located on the output shaft end of the hydraulic rod 33; and a jacking member 36 located on the surface of the driven synchronous pulley 34.

[0043] In this embodiment, a vibration device for lithium-ion batteries is provided. The lithium-ion battery can be fixed by the fixing component 2, and then the fixing component 2 can vibrate within the mounting body 1 under the action of the jacking mechanism 3. This helps the electrolyte in the lithium-ion battery to better wet the electrode material and remove air bubbles inside the lithium-ion battery, thereby improving the performance and consistency of the lithium-ion battery.

[0044] Furthermore, such as Figure 2 As shown, in the preferred embodiment of this utility model, the mounting body 1 further includes two sliding grooves 11, which are symmetrically opened on the inner side of the mounting body 1.

[0045] Furthermore, such as Figure 3-4 As shown, the fixing component 2 in the preferred embodiment of this utility model includes two return springs 21, respectively disposed inside the two sliding grooves 11; two sliding blocks 22, respectively slidably disposed inside the two sliding grooves 11; a fixing box 23, disposed between the outer sides of the two sliding blocks 22; two threaded rods 24, symmetrically and rotatably disposed inside the fixing box 23; a fixing plate 25, respectively and rotatably disposed at one end of the two threaded rods 24 located inside the fixing box 23; and an abutment block 26, disposed on the lower surface of the fixing box 23.

[0046] Furthermore, two sliding blocks 22 are respectively located at the right ends of the two return springs 21; the fixing plate 25 is a rubber fixing plate, which can prevent the fixing plate 25 from damaging the outside of the lithium-ion battery when fixing the lithium-ion battery.

[0047] In this embodiment, several preferred embodiments of the fixing component 2 are given. By placing the lithium-ion battery into the fixing box 23 and then rotating the two threaded rods 24, the two threaded rods 24 drive the fixing plate 25 to move. In this way, the two fixing plates 25 can fix the lithium-ion battery in the fixing box 23, thereby preventing the lithium-ion battery from colliding with the inside of the fixing box 23 when it is vibrating, which would lead to damage to the lithium-ion battery.

[0048] Furthermore, such as Figure 5-6 As shown, the jacking mechanism 3 in the preferred embodiment of this utility model further includes an AC motor 31 located inside the mounting body 1; a transmission synchronous pulley 32 located at the output end of the AC motor 31; and a synchronous toothed belt 35 that can be sleeved between the inner sides of the transmission synchronous pulley 32 and the driven synchronous pulley 34.

[0049] Preferably, there are three driven synchronous pulleys 34, and the three driven synchronous pulleys 34 are arranged together axially in sequence. The lowermost driven synchronous pulley 34 is rotatably mounted on the output end of the hydraulic rod 33, and the actuating member 36 is mounted on the upper surface of the uppermost driven synchronous pulley 34. The specifications and dimensions of the three driven synchronous pulleys 34 are all different.

[0050] Furthermore, the actuating member 36 includes a mounting block 361 disposed on the upper surface of the driven synchronous pulley 34; a mounting groove 362 formed on the upper surface of the mounting block 361; a mounting plate 363 disposed on the inner side of the mounting groove 362; a guide rod 364 slidably disposed on the inner side of the mounting plate 363; an actuating block 365 disposed on the left end face of the guide rod 364; and a lead screw 366 rotatably disposed on the inner side of the mounting plate 363, with the left end of the lead screw 366 rotatably disposed on the right side of the actuating block 365.

[0051] More specifically, the left side of the actuating block 365 contacts the right side of the abutting block 26, and the contact surface between the actuating block 365 and the abutting block 26 is an arc-shaped surface; the outer side of the lead screw 366 is threadedly connected to the inner side of the mounting plate 363.

[0052] This embodiment provides several preferred embodiments of the jacking mechanism 3. An AC motor 31 drives a driven synchronous pulley 34 to rotate via a synchronous toothed belt 35. The rotating driven synchronous pulley 34 drives the jacking block 365 on the mounting block 361 to rotate. When the jacking block 365 contacts the right side of the contact block 26, it pushes the fixing box 23 to the left. As the fixing box 23 moves, it compresses the return spring 21. When the jacking block 365 no longer contacts the outside of the contact block 26, the fixing box 23 returns to its original position to the right under the action of the return spring 21. Thus, with the continuous rotation of the AC motor 31, the fixing box 23 continuously reciprocates left and right, thereby oscillating the lithium-ion battery inside the fixing box 23. This helps the electrolyte in the lithium-ion battery better wet the electrode material and removes air bubbles inside the lithium-ion battery, thereby improving the performance and consistency of the lithium-ion battery. Furthermore, the synchronous toothed belt 35... Five synchronous pulleys 34 are fitted inside each other. The synchronous toothed belt 35 is fitted inside each of the driven synchronous pulleys 34, causing the hydraulic rod 33 to drive the driven synchronous pulleys 34 to move up and down. This ensures that the transmission synchronous pulley 32 can drive the driven synchronous pulleys 34 to rotate normally through the synchronous toothed belt 35. By fitting the synchronous toothed belt 35 inside each of the driven synchronous pulleys 34, the rotation speed of the jacking block 365 on the mounting block 361 driven by the AC motor 31 can be adjusted, thereby adjusting the oscillation speed of the lithium-ion battery. By rotating the lead screw 366, the lead screw 366 will drive the jacking block 365 to move, thereby adjusting the distance between the jacking block 365 and the axis of the hydraulic rod 33. This allows the oscillation amplitude of the jacking block 365 on the lithium-ion battery to be adjusted, so that the jacking mechanism 3 can fully wet the electrolyte in different types of lithium-ion batteries and also prevent the jacking mechanism 3 from damaging the lithium-ion battery during oscillation.
