Description

Technical Field

[0001] This utility model relates to the technical field of lithium-ion battery manufacturing equipment, specifically to a cleaning tool for aluminum-cased battery shells. Background Technology

[0002] With the development of portable electronic devices, electric vehicles and other fields, the requirements for the performance, safety and lifespan of lithium-ion batteries are getting higher and higher. During transportation and storage, batteries are subject to collisions, compression, dust and moisture, which threaten battery performance and safety. In addition, the battery pack casing may be electrified, posing an electrical safety hazard. Therefore, it is necessary to coat lithium-ion batteries with a blue film.

[0003] Chinese patent CN219817329U discloses a cleaning fixture for aluminum-cased batteries. This fixture uses a mixture of dry ice and compressed air, employing a high-speed jet of air to quickly clean the electrolyte or foreign matter from the battery casing. It fully utilizes the kinetic energy of the dry ice particles, the thermal shock effect of dry ice, and the sublimation effect of dry ice to remove dirt from the aluminum casing surface, achieving a fast, efficient, and safe cleaning. Crystalline powder or dust detached from the casing surface is sucked into a vacuum cleaner through a suction nozzle, where the vacuum cleaner filters out and collects the dust particles.

[0004] When using the aforementioned fixture, the battery needs to be placed inside the battery clamp for fixation. However, to effectively secure the battery, the inner wall of the clamp must fit the battery as closely as possible. A small gap can easily lead to scratches and abrasions on the battery casing, and the resulting debris falling into the clamp adds extra cleaning work for the worker. While a larger gap between the clamp and the battery can prevent scratches and abrasions, it results in poorer battery fixation. Under the influence of the high-speed jet of air, the battery is more likely to collide with the inner wall of the clamp, potentially affecting its usability. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning tool for aluminum-cased battery shells, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A cleaning fixture for aluminum-cased batteries includes a cleaning table with mounting slots on its surface. A cleaning turntable is rotatably mounted inside the mounting slots, and the surface of the cleaning turntable has electrode clearance openings. Four through slots are formed on the surface of the cleaning turntable, and L-shaped rods are slidably mounted inside the through slots. Clamping plates are mounted on the tops of the L-shaped rods. A clamping mechanism is provided on the underside of the cleaning turntable, enabling the four clamping plates to move simultaneously inwards.

[0008] It can be seen that by driving the four clamping plates to move inward simultaneously through the clamping mechanism, the four sides of the battery can be clamped. Since the clamping plates are pressed vertically against the outer surface of the battery, there will be no scratching or friction on the battery casing, and the generation of debris is avoided, reducing the workload of workers and providing a better fixation effect for the battery.

[0009] Furthermore, the clamping mechanism includes a pull rod located below the cleaning turntable, a disc mounted on the top of the pull rod, four wedge blocks mounted on the outer surface of the disc, wedge grooves being formed on the surfaces of the four L-shaped crossbars, and the wedge blocks being positioned within the wedge grooves and engaging with them in a pressing fit.

[0010] Furthermore, a connecting rod is mounted at the bottom of the pull rod via a bearing, and a pedal is mounted at the bottom of the connecting rod. Support legs are installed at each of the four corners of the bottom of the cleaning table, and a horizontal plate is installed between the four support legs. Two guide rods are symmetrically mounted on the upper surface of the horizontal plate, and the pedal is slidably mounted on the outside of the guide rods.

[0011] Furthermore, four fixing blocks are installed on the lower surface of the cleaning turntable, and each of the four fixing blocks corresponds to one of the four L-shaped rods. Telescopic rods are installed on the outer surface of the fixing blocks, and the ends of the telescopic rods are connected to the L-shaped rods. Springs are fitted on the outer surface of the telescopic rods, and the two ends of the springs abut against the fixing blocks and the L-shaped rods, respectively.

[0012] Furthermore, the outer surface of the clamp is provided with a rubber pad.

[0013] Furthermore, the side surface of the cleaning turntable is evenly distributed with balls, and the inner wall of the mounting slot is provided with guide grooves that are compatible with the balls.

[0014] Furthermore, a limit block is installed at the end of the guide rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. This utility model uses a clamping mechanism to move four clamping plates inward simultaneously, which can clamp the four sides of the battery. Since the clamping plates are pressed vertically against the outer surface of the battery, they will not scratch or rub the battery casing, and will avoid the generation of debris, reduce the workload of workers, and provide a better fixation effect for the battery.

[0017] 2. This utility model uses a worker stepping on a pedal to lower a disc, thereby clamping and fixing the battery. Compared with driving methods such as cylinders and electric push rods, it is not only cheaper but also more flexible in operation. The battery is placed by hand and fixed by foot, without interference between the two, thus improving the overall cleaning efficiency and significantly reducing the risk of fingers being pinched during operation, making it safer.

[0023] 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.

[0024] Please see Figures 1-4 This utility model provides a cleaning fixture for aluminum-cased batteries, including a cleaning table 1. The surface of the cleaning table 1 has a mounting slot 101, and a cleaning turntable 2 is rotatably mounted inside the mounting slot 101. The surface of the cleaning turntable 2 has an electrode clearance opening 201. The surface of the cleaning turntable 2 has four through slots 202, and an L-shaped rod 203 is slidably mounted inside the through slots 202. A clamping plate 204 is mounted on the top of the L-shaped rod 203. A clamping mechanism 3 is provided on the lower side of the cleaning turntable 2, which enables the four clamping plates 204 to move inward simultaneously.

[0025] When in use, first place the battery on the cleaning turntable 2 and between the four clamping plates 204. Then, the clamping mechanism 3 drives the four clamping plates 204 to move inward at the same time and press them against the four sides of the battery, thereby achieving the function of clamping and fixing. Then, you can hold the blow gun and the vacuum nozzle to perform cleaning operations. The structure, usage method and cleaning principle of the blow gun and the vacuum nozzle have been disclosed in the patent, so they will not be described in detail here.

[0026] Because the clamp 204 is pressed vertically onto the outer surface of the battery, it does not cause scratches or friction to the battery casing, avoids the generation of debris, reduces the workload of workers, and provides a better fixation effect for the battery.

[0027] Furthermore, compared to the patented design where the cleaning turntable rotates as a whole, requiring the dry ice maker and vacuum cleaner to be placed on the ground or elsewhere, this cleaning tool features a design where the cleaning turntable 2 rotates while the cleaning table 1 remains stationary. Therefore, the dry ice maker and vacuum cleaner can be placed on the cleaning table 1, making it more convenient to use.

[0028] Preferably, the clamping mechanism 3 includes a pull rod 301 disposed below the cleaning turntable 2, a disc 302 mounted on the top of the pull rod 301, four wedge blocks 303 mounted on the outer surface of the disc 302, and wedge grooves 304 opened on the surface of the four L-shaped rods 203, and the wedge blocks 303 are disposed in the wedge grooves 304 and squeezed and cooperate with them.

[0029] When the lever 301 is pulled down, it causes the disc 302 to descend. Because the inclined surfaces between the wedge block 303 and the wedge groove 304 press against each other, the four L-shaped rods 203 can move inward simultaneously while the disc 302 descends, and the clamping plate 204 clamps and fixes the battery.

[0030] Preferably, a connecting rod 401 is mounted on the bottom of the pull rod 301 via a bearing 4, and a pedal 402 is mounted on the bottom of the connecting rod 401. Support legs 102 are mounted at each of the four corners of the bottom of the cleaning table 1, and a cross plate 103 is mounted between the four support legs 102. Two guide rods 104 are symmetrically mounted on the upper surface of the cross plate 103, and the pedal 402 is slidably mounted on the outside of the guide rods 104.

[0031] During operation, the worker can hold the blow gun and suction nozzle in one hand, hold the battery in the other hand and place it between the four clamps 204, and step down on the pedal 402 with one foot. The pedal 402 drives the pull rod 301 to descend through the connecting rod 401, so that the clamps 204 can clamp and fix the battery. Since the pull rod 301 and the connecting rod 401 are connected by the bearing 4, it does not affect the rotation of the cleaning turntable 2. Since the hands and feet can be operated separately without interference, the cleaning efficiency of the battery can be improved. Compared with the driving methods such as cylinders and electric push rods, it is not only cheaper but also has less impact, which greatly reduces the risk of fingers being pinched during operation and makes it safer.

[0032] Preferably, four fixing blocks 5 are installed on the lower surface of the cleaning turntable 2, and the four fixing blocks 5 correspond to four L-shaped rods 203 respectively. A telescopic rod 501 is installed on the outer surface of the fixing block 5, the end of the telescopic rod 501 is connected to the L-shaped rod 203, and a spring 502 is sleeved on the outer surface of the telescopic rod 501. The two ends of the spring 502 abut against the fixing block 5 and the L-shaped rod 203 respectively.

[0033] When the L-shaped rod 203 presses the clamping plate 204 against the battery surface, the telescopic rod 501 and the spring 502 are compressed. Therefore, when the pedal 402 is released, the compressed spring 502 can push the L-shaped rod 203 to reset and move the clamping plate 204 away from the battery, thus facilitating the insertion and removal of the battery.

[0034] Preferably, the outer surface of the clamping plate 204 is provided with a rubber pad 205.

[0035] The rubber pad 205 acts as a buffer when the clamp 204 contacts the battery, reducing the impact on the battery and preventing it from being affected.

[0036] Preferably, the side surface of the cleaning turntable 2 is evenly distributed with balls 206, and the inner wall of the mounting slot 101 is provided with a guide groove that matches the balls 206.

[0037] The cleaning turntable 2 can rotate smoothly inside the mounting slot 101 by means of the ball bearing 206 and the matching guide groove.

[0038] Preferably, a limit block 105 is installed at the end of the guide rod 104.

[0039] By setting the limit block 105, the rising height of the pedal 402 is limited, thereby preventing the wedge block 303 from disengaging from the wedge groove 304.

[0040] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
