Description

Technical Field

[0001] This utility model belongs to the field of battery production technology, and relates to a battery component cleaning equipment, and more particularly to a centrifugal device for cleaning battery aluminum shells. Background Technology

[0002] The aluminum casing of a lithium battery is the outer shell material, mainly made of aluminum alloy. It is used to protect the internal structure of the battery and provide mechanical strength. With the rapid development of the new energy industry, the aluminum casing is a key structural component of power batteries and energy storage batteries. The cleanliness requirements during its production process are extremely strict. Oil stains, metal shavings and other contaminants will adhere to the surface of the aluminum casing during stamping, transportation and other processes. It must be thoroughly cleaned before assembly. After cleaning, special centrifugal equipment is needed to spin dry the water.

[0003] In the existing technology, most centrifuge devices can centrifuge and dehydrate the cleaned aluminum battery shells, but their functions are relatively simple. Their interiors are usually smooth cylinder walls. During high-speed centrifugation, impurities thrown out of the aluminum shells will adhere to the cylinder walls and are difficult to remove quickly. This not only causes contamination of the cylinder walls and affects the cleanliness of the equipment, but also makes it difficult to clean the cylinder walls thoroughly after repeated use, forming stubborn stains. It can even cause secondary contamination of aluminum shells in subsequent batches of centrifugation, affecting cleaning quality and production efficiency.

[0004] Therefore, it is necessary to propose a centrifugal device for cleaning aluminum battery casings to solve the aforementioned technical problem of difficult cleaning caused by stubborn stains forming on the cylinder wall. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a centrifugal device for cleaning aluminum battery shells, which has the advantage of being easy to clean and solves the problem of difficult cleaning caused by stubborn stains forming on the cylinder wall.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution:

[0007] A centrifugal device for cleaning aluminum battery casings includes a centrifugal cleaning drum. A cleaning assembly is disposed within the centrifugal cleaning drum. The cleaning assembly includes two sets of support members symmetrically arranged within the centrifugal cleaning drum. Several support rods are disposed on the outer side of each support member. A positioning plate is disposed between the upper and lower support rods. A scraper is disposed on the positioning plate, with its other side abutting against the inner wall of the centrifugal cleaning drum. A driving part connected to the support members is disposed on the centrifugal cleaning drum, and the driving part is used to drive the scraper to perform circumferential movement.

[0008] Preferably, the support member is cylindrical in shape, and a plurality of the support rods are arranged at equal intervals on the outer side of the support member.

[0009] Preferably, the scraper is elongated and its height is less than that of the positioning plate.

[0010] Preferably, the scraper is made of any one of polyurethane, rubber, or silicone, and the outer edge of the scraper is in contact with the inner wall of the centrifugal cleaning cylinder.

[0011] Preferably, a horizontal plate is provided on the centrifugal washing cylinder, and a drive module is provided on the horizontal plate. The output end of the drive module is connected to the upper support member.

[0012] Preferably, the inner bottom wall of the centrifugal cleaning cylinder is provided with a bearing seat, and the lower support member is rotatably connected to the centrifugal cleaning cylinder through the bearing seat.

[0013] Preferably, the positioning plate is provided with a positioning frame, and the positioning frame is provided with a battery aluminum shell placement frame.

[0014] Preferably, the battery aluminum shell placement frame is a cuboid frame, and the longitudinal cross-section of the positioning frame is rectangular.

[0015] Preferably, the battery aluminum shell placement frame is provided with a plurality of reinforcing frames, and the plurality of reinforcing frames are arranged at equal intervals along the vertical direction.

[0016] Preferably, the bottom of the battery aluminum shell placement frame is provided with at least one support bar, and the support bar is evenly spaced at the bottom of the battery aluminum shell placement frame.

[0017] The present invention adopts the above technical solution and has the following technical effects compared with the prior art:

[0018] (1) The centrifugal device for cleaning aluminum battery shells has a scraper that abuts against the inner wall of the centrifugal cleaning cylinder. The scraper moves circumferentially under the drive of the drive unit. It can automatically scrape off the oil, water film and impurities attached to the cylinder wall during or after centrifugal dehydration, effectively preventing the accumulation of pollutants to form stubborn stains. It realizes the self-cleaning of the centrifugal cylinder and fundamentally solves the problem of the difficulty in cleaning the cylinder wall after contamination of traditional equipment.

[0019] (2) The centrifugal device for cleaning aluminum battery shells enhances the overall structural strength and rigidity of the frame by setting multiple reinforcing skeletons distributed at equal intervals along the vertical direction on the aluminum battery shell placement frame. This makes the aluminum battery shell placement frame less prone to deformation or damage when subjected to high-speed centrifugal force load for a long time, effectively extending its service life and ensuring the safety and stability of the centrifugation process.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example 1:

[0030] Please see Figure 1-3 A centrifugal device for cleaning aluminum battery casings in this embodiment includes a centrifugal cleaning cylinder 100, and a cleaning component 200 is provided inside the centrifugal cleaning cylinder 100.

[0031] It should be noted that the centrifugal cleaning cylinder 100 is a common piece of equipment in the prior art, and the working principle and usage of the centrifugal cleaning cylinder 100 are well known to those skilled in the art of battery production, and will not be elaborated further in this application.

[0032] It should be added that the centrifugal washing drum 100 is equipped with a drain port, which is used to remove the water and impurities generated inside the centrifugal washing drum 100 after centrifugation in a timely manner.

[0033] When it is necessary to centrifuge and dehydrate the aluminum battery casing, the aluminum battery casing to be dehydrated is first neatly placed in a battery casing box specifically for placing the aluminum battery casing. The battery casing box is a common piece of equipment in the field of battery production technology, and will not be described in detail in this application.

[0034] The cleaning assembly 200 includes two sets of support members 201 symmetrically arranged inside the centrifugal cleaning cylinder 100. Several support rods 202 are arranged on the outer side of the support members 201. A positioning plate 203 is arranged between the upper and lower support rods 202. A scraper 204 is arranged on the positioning plate 203, and its other side abuts against the inner wall of the centrifugal cleaning cylinder 100. A drive unit is arranged on the centrifugal cleaning cylinder 100 and connected to the support members 201. The drive unit is used to drive the scraper 204 to perform circumferential movement.

[0035] In application, the aluminum battery shells to be dehydrated are neatly placed in a battery shell box specifically for storing aluminum battery shells. Then, the battery shell boxes containing the aluminum battery shells are placed into the centrifugal cleaning drum 100. The drive unit is started, and the drive unit drives the support member 201 to rotate. The support member 201 drives the positioning plate 203 to move circumferentially through the support rod 202, thereby causing the scraper 204 set on the positioning plate 203 to move circumferentially along the inner wall of the centrifugal cleaning drum 100.

[0036] During the centrifugal dehydration process, the liquid and impurities ejected from the battery aluminum shell impact the inner wall of the centrifugal cleaning drum 100. The circumferential movement of the scraper 204 can promptly scrape off the impurities adhering to the drum wall, allowing them to flow down the drum wall and be discharged under the action of gravity and centrifugal force. Thus, while achieving the centrifugal dehydration function, the inner wall of the centrifugal cleaning drum 100 is automatically cleaned, effectively preventing the residue and accumulation of pollutants.

[0037] Example 2:

[0038] The basic content is the same as in Example 1, except that:

[0039] Please see Figure 3-4 In this embodiment, the support member 201 is cylindrical in shape, and several support rods 202 are equally spaced on the outside of the support member 201.

[0040] The scraper 204 is elongated, and its height is less than that of the positioning plate 203.

[0041] The scraper 204 is made of any one of polyurethane, rubber, or silicone, and the outer edge of the scraper 204 is in contact with the inner wall of the centrifugal cleaning cylinder 100.

[0042] Understandably, the scraper 204 is made of flexible materials such as polyurethane, rubber or silicone, which gives it good elasticity when it is in contact with the cylinder wall. This ensures the effectiveness of scraping off dirt and avoids scratches or excessive wear that the rigid scraper 204 may cause to the cylinder wall. The elongated design and the design that the scraper 204 is lower than the positioning plate 203 ensures a sufficient scraping area while preventing the scraper 204 from deforming or being damaged due to excessive force, thus optimizing its structural strength and durability.

[0043] A horizontal plate 205 is provided on the centrifugal washing cylinder 100, and a drive module 206 is provided on the horizontal plate 205. The output end of the drive module 206 is connected to the upper support member 201.

[0044] It should be noted that the drive module 206 is connected to the control unit. The control unit is used to control the output end of the drive module 206 to rotate at a constant speed, thereby realizing the rotation of the scraper 204. The control unit and its working principle are well known to those skilled in the art, and will not be described in this embodiment.

[0045] The drive module 206 includes, but is not limited to, any one of a speed-regulating motor, a servo motor, or a DC motor;

[0046] Preferably, the drive module 206 in this application is a speed-regulating motor.

[0047] The inner bottom wall of the centrifugal washing cylinder 100 is provided with a bearing seat 207, and the lower support member 201 is rotatably connected to the centrifugal washing cylinder 100 through the bearing seat 207.

[0048] Furthermore, the cylindrical support member 201 and the equally spaced support rods 202 together form a symmetrical and balanced force-bearing frame, which can effectively reduce vibration during high-speed rotation and ensure the smooth operation of the entire cleaning assembly 200. At the same time, the upper end is powered by the drive module 206, and the lower end is rotatably connected through the bearing seat 207, forming a stable and reliable rotation system, which greatly improves the mechanical stability and service life of the device under high-speed centrifugal conditions.

[0049] When in use, the drive module 206 starts and drives the upper cylindrical support 201 to rotate through the output end of the drive module 206. Since the support rods 202 are evenly distributed, the load is evenly transmitted, making the entire cleaning assembly 200 run smoothly. The lower support 201 achieves stable rotation through the bearing seat 207, forming a reliable bottom support.

[0050] During the centrifugation process, the elongated scraper 204, made of flexible materials such as polyurethane, rubber, or silicone, always adheres to the inner wall of the centrifugal cleaning cylinder 100. Its height is lower than that of the positioning plate 203, which ensures an effective scraping area and avoids interference affecting the structural strength. During the circumferential movement, the scraper 204 can effectively scrape off the liquid and impurities on the cylinder wall. Its flexibility ensures the scraping effect and avoids rigid wear on the cylinder wall, achieving the dual effect of efficient self-cleaning and equipment protection.

[0051] Example 3:

[0052] The basic content is the same as in Example 1, except that:

[0053] Please see Figure 2 and Figure 4-6 In this embodiment, a positioning frame 208 is provided on the positioning plate 203, and a battery aluminum shell placement frame 209 is provided on the positioning frame 208.

[0054] The battery aluminum shell placement frame 209 is a cuboid frame, and the longitudinal section of the positioning frame 208 is rectangular.

[0055] It should be noted that by setting up a rectangular frame structure for placing aluminum battery casings 209 and a rectangular positioning frame 208 that fits between them, a regular and stable loading unit is constructed. This effectively constrains the aluminum battery casing box, which is specifically designed to hold the aluminum battery casings, within a fixed space during centrifugation. This avoids chaotic collisions and friction between aluminum casings and between the aluminum casings and the equipment caused by high-speed rotation, significantly reducing the risk of scratches and deformation on the product surface and improving the yield of finished products.

[0056] The battery aluminum casing placement frame 209 is provided with several reinforcing skeletons 210, which are evenly spaced along the vertical direction.

[0057] Furthermore, the equally spaced reinforcing frame 210 enhances the overall structural strength and resistance to bending and torsional deformation of the battery aluminum shell placement frame 209. This makes the battery aluminum shell placement frame 209 less prone to fatigue damage or permanent deformation when subjected to cyclic loads from high-speed centrifugal force over a long period of time, effectively extending its service life and ensuring the reliability and safety of the equipment during long-term operation.

[0058] The bottom of the battery aluminum shell placement frame 209 is provided with at least one support bar 211, which are evenly spaced at the bottom of the battery aluminum shell placement frame 209.

[0059] In application, the aluminum battery casings to be dehydrated are neatly placed in the battery casing box specifically for placing the aluminum battery casings. Then, the battery casing boxes are placed into the battery casing placement frame 209 in sequence. After the drive unit is started, the entire cleaning assembly 200 begins to rotate and enters the centrifugal dehydration process. During this process, the battery casing boxes are constrained within the rectangular frame structure of the battery casing placement frame 209, which effectively avoids mutual collisions and surface damage caused by chaotic movement under high-speed rotation.

[0060] Several reinforcing frames 210 arranged at equal intervals along the vertical direction enhance the overall rigidity and deformation resistance of the battery aluminum shell placement frame 209, ensuring that it can maintain structural integrity and stability under high-speed centrifugal load and extending its service life. The support strips 211 arranged at equal intervals at the bottom of the placement frame provide a reliable support plane for the aluminum shell and prevent it from falling off from the bottom.

[0061] In summary, the working principle of this centrifugal device for cleaning battery aluminum casings is as follows:

[0062] The aluminum battery shells to be dehydrated are neatly placed in a battery shell box specifically for placing the aluminum battery shells. Then, the battery shell boxes are placed into the battery shell placement frame 209. The drive module 206 is started, and the drive module 206 drives the support member 201 to rotate. The support member 201 drives the positioning plate 203 to move circumferentially through the support rod 202, thereby causing the scraper 204 set on the positioning plate 203 to move circumferentially along the inner wall of the centrifugal cleaning cylinder 100.

[0063] During the centrifugal dehydration process, the liquid and impurities ejected from the battery aluminum shell impact the inner wall of the centrifugal cleaning drum 100. The circumferential movement of the scraper 204 can promptly scrape off the impurities adhering to the drum wall, allowing them to flow down the drum wall and be discharged under the action of gravity and centrifugal force. Thus, while achieving the centrifugal dehydration function, it automatically completes the cleaning of the inner wall of the centrifugal cleaning drum 100, effectively preventing the residue and accumulation of pollutants.

[0064] During this process, the battery aluminum shell box containing the battery aluminum shell is constrained within the rectangular frame structure of the battery aluminum shell placement frame 209, effectively avoiding mutual collisions and surface damage caused by chaotic movement under high-speed rotation.

[0065] Several reinforcing frames 210 arranged at equal intervals along the vertical direction enhance the overall rigidity and deformation resistance of the battery aluminum shell placement frame 209, ensuring that it can maintain structural integrity and stability under high-speed centrifugal load and extending its service life. The support strips 211 arranged at equal intervals at the bottom of the placement frame provide a reliable support plane for the battery aluminum shell box specifically for placing the battery aluminum shell, preventing it from falling off from the bottom.
