Description

Technical Field

[0001] This utility model relates to the field of raw material cleaning technology, and more specifically, it relates to a cleaning device for aluminum alloy raw materials used in the positive electrode of lithium batteries. Background Technology

[0002] Lithium-ion batteries are a common type of battery in our daily lives, with the positive and negative electrodes located at opposite ends. The positive electrode is typically manufactured using a stamping process, where sheet-like raw materials are placed into a stamping press and pressed into a sheet-like component of a specific shape. During this process, oil or other contaminants may adhere to the material's surface, necessitating subsequent cleaning treatment using cleaning equipment.

[0003] Existing cleaning equipment still has the following problems: During the cleaning process, due to the surface tension of the raw material sheets and the action of fluids, the sheets are prone to adsorption and overlap, forming obstructed areas that prevent the cleaning fluid from fully penetrating and contacting them. As a result, some oil and impurities remain between the laminated surfaces, making them difficult to remove completely and directly affecting the quality of subsequent processes and the consistency of battery performance. Furthermore, after cleaning, due to the surface tension of the materials and the viscosity of the cleaning fluid itself, a large amount of liquid remains attached to the surface and gaps of the raw material sheets, making it difficult to completely flow off under its own weight. Residual cleaning fluid not only increases the drying burden but may also introduce secondary contamination, affecting the effectiveness of subsequent processes such as coating, baking, or assembly, and ultimately the quality of the finished product.

[0004] In view of this, we propose a cleaning device for aluminum alloy raw materials for lithium battery cathodes. Utility Model Content

[0007] The present invention is further provided that the rotating sleeve is provided with through grooves distributed at equal intervals.

[0014] 2. This utility model uses a limiting rod to press the connecting ring, which reliably fixes the raw material pieces during the cleaning process, effectively preventing them from shifting, stacking, or blocking each other under the impact of liquid flow, thereby ensuring that oil stains and impurities are cleaned and improving the uniformity and thoroughness of cleaning.

[0021] Please see Figures 1-5 A cleaning device for aluminum alloy raw materials used in lithium battery cathodes includes a cleaning tank 1, a top cover 2 fixedly connected to the upper side of the cleaning tank 1, the cleaning tank 1 can be an ultrasonic cleaner, a sliding door 3 slidably connected to the top cover 2, two electric guide rails 4 fixedly connected to the inner wall of the top cover 2, an electric slider 5 slidably connected inside the electric guide rails 4, a horizontal plate 6 fixedly connected between the two electric sliders 5, a plurality of rotating sleeves 7 rotatably connected to the horizontal plate 6, support plates 8 fixedly connected to the rotating sleeves 7 at equal intervals, connecting rings 9 circumferentially evenly distributed detachably connected to the support plates 8, a support net 10 fixedly connected to the bottom of the connecting rings 9, a limit structure provided for the rotating sleeves 7, and through grooves 11 evenly distributed circumferentially distributed on the rotating sleeves 7.

[0022] Please see Figure 4 and Figure 5The limiting structure includes a sliding column 12, which is slidably connected to the rotating sleeve 7. A connecting plate 13 is slidably connected to the through groove 11, and the connecting plate 13 is fixedly connected to the sliding column 12. The rotating sleeve 7 is slidably connected to sliding sleeves 14 with equal spacing, and the sliding sleeves 14 are fixedly connected to limiting rods 15 with equal spacing in the circumferential direction. The rotating sleeve 7 is fixedly connected to a first pulley 16. The horizontal plate 6 is fixedly connected to a motor 17, and the output shaft of the motor 17 is fixedly connected to a second pulley 18. A belt 19 is wound between the second pulley 18 and the first pulley 16. The horizontal plate 6 is fixedly connected to an electric push rod 20, and the telescopic end of the electric push rod 20 is fixedly connected to a connecting piece 21, which is rotatably connected to the sliding column 12.

[0023] The working principle of this utility model: The raw material sheet is placed inside the connecting ring 9 and supported by the support net 10. Then, the connecting ring 9 is placed on the support plate 8. The sliding door 3 is then closed, and the electric push rod 20 is activated. The telescopic end of the electric push rod 20 drives the connecting piece 21 to move downward. The connecting piece 21 drives the sliding column 12 to move downward along the rotating sleeve 7. The sliding column 12 drives the sliding sleeve 14 to move downward through the connecting plate 13. The sliding sleeve 14 drives the limiting rod 15 to move downward until the limiting rod 15 is pressed against the connecting ring 9 on the lower side, thus fixing the connecting ring 9 and limiting the raw material sheet on the upper side of the support net 10 to ensure the stability of the raw material sheet during cleaning. Then, the two electric sliders 5 are activated, which drive the horizontal plate 6 and the parts on it to move downwards until all the support plates 8 are immersed in the cleaning solution in the cleaning tank 1. The cleaning tank 1 cleans the raw material pieces and starts the motor 17. The output shaft of the motor 17 drives the two first pulleys 16 to rotate through the second pulley 18 and the belt 19. At this time, the rotating sleeve 7 rotates around the horizontal plate 6, thereby causing the cleaning solution to impact the raw material pieces, thus improving the cleaning effect on the raw material pieces.

[0024] After cleaning is complete, the electric slider 5 is reset, the sliding plate moves upward to reset, and the support plate 8 is removed from the cleaning solution. The speed of the output shaft of the motor 17 is increased, and the rotating sleeve 7 drives the support plate 8 to rotate. Under the action of centrifugal force, the cleaning solution on the raw material sheet is thrown off, reducing the amount of cleaning solution residue on the original sheet. The electric push rod 20 is started, and the telescopic end of the electric push rod 20 drives the connecting piece 21 to reset. The sliding column 12 drives the sliding sleeve 14 and the limit rod 15 to move upward to reset, releasing the limit on the connecting ring 9. The sliding door 3 is opened, and the connecting ring 9 is removed from the support plate 8.

[0025] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
