Description

Technical Field

[0001] This utility model belongs to the field of lithium battery cell impregnation technology, specifically relating to an easy-to-operate lithium battery cell impregnation device. Background Technology

[0002] A lithium-ion battery cell immersion device is used to immerse the lithium-ion battery cell with electrolyte. Its design and working principle are crucial for ensuring good contact between the electrolyte and the electrodes, improving conductivity, and facilitating lithium-ion transport. The main function of the lithium-ion battery cell immersion device is to achieve full contact between the cell and the electrolyte, thereby improving the performance of the lithium-ion battery. Through specific design and processes, the device allows the electrolyte to penetrate evenly into every corner of the cell. This process is similar to watering a dry sponge, allowing the cell to "absorb" the electrolyte, thus ensuring efficient lithium-ion transport during charging and discharging. The device also prevents collisions between cells during immersion, preventing damage. Traditionally, lithium-ion battery cells are immersed one at a time inside an immersion tank, which is not suitable for large-scale immersion. Therefore, we propose an easier-to-operate lithium-ion battery cell immersion device. 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. 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.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: an easy-to-operate lithium battery cell immersion device, including an immersion tank 1, a tank cover 2 provided at the top of the immersion tank 1, a pop-up immersion mechanism provided inside the immersion tank 1, and a connecting and engaging mechanism provided between the tank cover 2 and the immersion tank 1. The pop-up immersion mechanism includes a pop-up component and an immersion limiting component.

[0022] In this embodiment, preferably, the pop-up component includes a fixing seat 100 fixed to the bottom of the immersion tank 1, and a fixing plate 101 is provided at the top of the fixing seat 100, which allows the immersion frame 300 to be connected to the fixing plate 101 and immersed into the interior of the immersion tank 1.

[0023] In this embodiment, preferably, the interior of the fixing base 100 is symmetrically provided with grooves 200, and the top of the interior of the grooves 200 is provided with a through hole 201 extending to the top of the fixing base 100. The bottom of the fixing plate 101 is symmetrically fixed with connecting rods 202, which pass through the interior of the through hole 201 and connect with the grooves 200, so that the fixing plate 101 can be connected with the fixing base 100. The interior of the grooves 200 is provided with a telescopic spring 203 connected to the connecting rod 202, which can drive the fixing plate 101 to reset and spring up.

[0024] In this embodiment, preferably, the immersion limiting component includes an immersion frame 300 disposed inside the immersion tank 1 and connected to the fixing plate 101. A drain outlet 301 is provided through the bottom end of the immersion frame 300. Filter screens 302 are symmetrically provided through both sides of the immersion frame 300. Operating handles 303 are symmetrically fixed at the top end of the immersion frame 300 to facilitate lifting and moving the immersion frame 300.

[0025] In this embodiment, preferably, the top of the fixed plate 101 is symmetrically provided with docking grooves 400, and the bottom of the immersion frame 300 is symmetrically fixed with docking blocks 401. The immersion frame 300 can be connected to the fixed plate 101 by engaging the docking blocks 401 with the docking grooves 400.

[0026] In this embodiment, preferably, the immersion tank 1 has symmetrically provided built-in grooves 500 on both sides inside, and a blocking block 501 is provided inside the built-in groove 500. A built-in spring 502 is connected between the blocking block 501 and the built-in groove 500. The inner wall of the built-in groove 500 has symmetrically provided sliding grooves 503. Sliding blocks 504 are symmetrically fixed on both sides of the blocking block 501. The sliding grooves 503 and the sliding blocks 504 are slidably connected, which can play a guiding role when the blocking block 501 moves.

[0027] In this embodiment, preferably, the connecting and engaging mechanism includes a connecting groove 600 symmetrically opened at the top of the immersion tank 1 and a connecting block 601 symmetrically fixed at the bottom of the tank cover 2. The connecting block 601 is engaged with the connecting groove 600 to facilitate the connection between the tank cover 2 and the immersion tank 1.

[0028] In this embodiment, preferably, the connecting block 601 has symmetrical slots 700 on both sides, and the inner wall of the connecting slot 600 is symmetrically fixed with buckles 701. By engaging the buckles 701 with the slots 700, the connecting block 601 can be limited to the inside of the connecting slot 600.

[0029] The working principle and usage process of this utility model are as follows: When it is necessary to impregnate lithium battery cells, first pull the cover 2, which causes the connecting block 601 to move outward from the inside of the connecting groove 600. At the same time, it causes the buckle 701 to be squeezed and separated from the groove 700, allowing the cover 2 to be separated from the top of the impregnation box 1. Then, push the blocking blocks 501 protruding on both sides of the inner wall of the impregnation box 1, which causes the built-in spring 502 to retract into the inside of the built-in groove 500. This causes the sliding groove 503 to slide inside the slider 504, which plays a guiding role. This releases the obstruction and limitation on the top of the impregnation frame 300. The connecting rod 202 slides inside the through hole 201 under the action of the telescopic spring 203, and moves upward inside the groove 200. This pushes the fixing plate 101 upward inside the immersion tank 1, simultaneously causing the immersion frame 300 to move upward and eject from the immersion tank 1. Then, the operating handle 303 can be grasped to lift the immersion frame 300, causing it to exit from inside the immersion tank 300. This also causes the docking block 401 to separate from the docking groove 400, allowing the immersion frame 300 to separate from the immersion tank 1. Then, a large number of lithium battery cells are placed one by one. Finally, the immersion frame containing the lithium battery cells is... 300. By operating the handle 303, lift and place the frame 300 into the immersion tank 1, so that the bottom end of the immersion frame 300 is embedded in the fixed base 100, and the docking block 401 engages with the docking groove 400 to connect them. Then, hold the handle 303 and press the immersion frame 300 down, so that the fixed plate 101 moves down and pushes the connecting rod 202 to slide and compress the telescopic spring 203 inside the groove 200 inside the through hole 201. At the same time, the top sides of the immersion frame 300 compress the protruding blocking blocks 501 on both sides of the inner wall of the immersion tank 1. Since the top of the blocking block 501 is inclined... The cut surface, therefore, when squeezed by external force, will retract into the interior groove 500, compressing the interior spring 502 and causing it to deform, so that the immersion frame 300 is completely inserted into the interior of the immersion box 1. At this time, the blocking block 501, under the action of the interior spring 502, is reset from the interior groove 500 and pops out to lock onto the top of the immersion frame 300, thus playing a blocking and limiting role. Then, the box cover 2 is covered back onto the top of the immersion box 1, so that the connecting block 601 is embedded into the interior of the connecting groove 600, and at the same time, the buckle 701 is squeezed and engaged with the groove 700, thus closing the top of the immersion box 1, and then the lithium battery cell immersion work is carried out.

[0030] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
