Description

Technical Field

[0001] The utility model belongs to the technical field of equipment cleaning, and in particular relates to an ultrasonic automatic cleaning machine. Background Art

[0002] With the rapid development of new energy technology, lithium batteries, as a core component, have increasingly higher performance and quality requirements. In the production process of lithium batteries, lithium battery copper foil, as one of the key materials, has a direct impact on the performance and service life of the entire lithium battery. The raw foil technology is a key step in the production of lithium battery copper foil. The operating status and process control of the equipment have a decisive influence on the quality of the copper foil.

[0003] In the foil production process, the cathode roller is the core component of copper foil production. The flatness of its surface plays a key role in the thin surface quality and uniformity of the copper foil. Therefore, it is very important to ensure the smoothness of the cathode roller surface. In the existing production process, the cathode roller will be polished before starting the machine to remove surface impurities and uneven parts to ensure that it can evenly absorb copper ions during the foil production process to form high-quality copper foil.

[0004] However, during the polishing process, the polishing brush is a tool that directly contacts the surface of the cathode roller, and its quality and cleanliness directly affect the surface quality of the cathode roller. The polishing brush is usually made of non-woven fabric as the main material. Due to the characteristics of the material itself, the non-woven fabric is prone to residual dust and other impurities generated during polishing after long-term use. If these impurities are not removed in time, they will cause secondary damage to the cathode roller during the polishing process, affecting its surface quality, and then affecting the quality of the copper foil, and may even cause equipment failure and cause production accidents; therefore, how to clean the polishing brush efficiently and safely has become a key issue in improving the quality of copper foil and production efficiency. Traditional cleaning methods mostly rely on manual or simple mechanical cleaning, which is not only inefficient, but also difficult to completely remove residual impurities in the non-woven fabric, and cannot meet the needs of modern production for high-quality copper foil.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model provides an ultrasonic automatic cleaning machine. Figure 1-4 As shown, the ultrasonic automatic cleaning machine includes: a chassis 1, wherein a cleaning pool 2 for cleaning polishing brushes is provided in the chassis 1, wherein a plurality of ultrasonic transducers 3 are provided in the cleaning pool 2; a drain pipe 4 for discharging dirty liquid, wherein the drain pipe 4 is fixedly connected to the bottom of the cleaning pool 2, and wherein an electromagnetic valve 5 is provided on the drain pipe 4; a spray pipe 6 for spraying cleaning liquid, wherein the spray pipe 6 is fixedly installed in the cleaning pool 2; a shielding shell, wherein the shielding shell is provided on the top of the chassis; a liftable placement seat 10 for placing the polishing brushes to be cleaned, wherein the placement seat 10 is provided in the shielding shell; a purge mechanism for blowing away the polishing brushes after cleaning, wherein the purge mechanism is provided on the chassis 1; and a lifting mechanism for regulating the lifting and lowering of the placement seat 10, wherein the lifting mechanism is provided in the shielding shell.

[0023] It should be noted that in the production process of lithium battery copper foil, the cathode roller is the core component of copper foil production, and its surface quality directly determines the thin surface quality and uniformity of the copper foil. As an important component of lithium batteries, the quality of copper foil is directly related to the overall performance and service life of lithium batteries. Therefore, ensuring the smoothness of the cathode roller surface is a crucial link in the copper foil production process; in order to achieve this goal, the cathode roller will undergo a polishing process before starting the machine. The main purpose of the polishing process is to remove impurities and uneven parts on the surface of the cathode roller, so that the surface becomes smooth, so that copper ions can be evenly adsorbed during the foil production process, and finally high-quality copper foil is formed; however, the quality and cleanliness of the polishing brush used in the polishing process also have an important influence on the surface quality of the cathode roller. Polishing brushes usually use non-woven fabrics as the main material. This material is widely used because of its soft and wear-resistant properties. However, after long-term use, dust and other impurities generated during the polishing process are easily accumulated between the fibers of non-woven fabrics. If these impurities are not removed in time, they will cause secondary damage to the cathode roller surface during the polishing process, such as scratches or indentations, thus affecting the surface quality of the cathode roller; more specifically, these residual impurities may cause uneven areas on the cathode roller surface, which cannot evenly adsorb copper ions during the foil production process, resulting in copper foil of uneven quality. Uneven copper foil will not only reduce the performance of lithium batteries, but may also cause battery failure, posing a threat to the safety of users; therefore, how to efficiently and safely clean the polishing brush has become a key issue in improving the quality and production efficiency of copper foil. Traditional cleaning methods, such as manual cleaning or simple mechanical cleaning, can remove impurities on the polishing brush to a certain extent, but they are inefficient and difficult to completely remove residual impurities in the non-woven fibers. These residual impurities will still damage the cathode roller surface when used next time, forming a vicious circle; in summary, in view of the cleaning problem of the polishing brush, it is necessary to develop an efficient and thorough cleaning method to ensure the cleanliness of the polishing brush, thereby ensuring the surface quality of the cathode roller and improving the production quality and efficiency of copper foil;

[0024] In this embodiment, the chassis 1 serves as the main structure of the entire ultrasonic automatic cleaning machine, providing a stable working environment for other components. Its solid structure and reasonable layout ensure the smooth progress of the cleaning process. The setting of the shielding shell can effectively prevent liquid splashing during the cleaning process and ensure the safety of the operator. The cleaning pool 2 is the main place for cleaning the polishing brush, and the cleaning liquid is stored inside, which provides the necessary conditions for ultrasonic cleaning. The ultrasonic transducer 3 is the core component of the ultrasonic automatic cleaning machine. It converts electrical energy into ultrasonic energy and transmits it to the cleaning liquid. The cavitation effect and vibration effect generated by the ultrasonic wave in the cleaning liquid can penetrate into the tiny gaps of the non-woven material and effectively remove dust and other impurities on the polishing brush. The drain pipe 4 is used to discharge the dirty liquid in the cleaning pool 2, and the electromagnetic valve 5 controls the switch of the drain pipe 4. After the cleaning is completed, the dirty liquid can be easily discharged by opening the electromagnetic valve 5 to prepare for the next cleaning. The spray pipe 6 is used to spray the cleaning liquid into the cleaning pool 2 to ensure that the polishing brush is always surrounded by the cleaning liquid during the cleaning process. This can improve the cleaning effect and ensure that every part of the polishing brush can be fully cleaned; the placement seat 10 is used to place the polishing brush to be cleaned. Its lifting design allows the polishing brush to be easily placed in and taken out of the cleaning tank 2. At the same time, the lifting mechanism can adjust the height of the placement seat 10 as needed to accommodate polishing brushes of different sizes; the blowing mechanism: the blowing mechanism blows the polishing brush after cleaning to remove residual moisture and impurities on the surface of the polishing brush. This helps to speed up the drying speed of the polishing brush and improve the cleaning efficiency.

[0025] In a further preferred embodiment of the utility model, the blowing mechanism includes: a box body 7 fixed on the top of the chassis 1 and located in the shielding shell; a hot air blower 8 arranged in the chassis 1; and an air blowing pipe 9 fixedly installed on the air outlet end of the hot air blower 8, and the air outlet end of the air blowing pipe 9 extends into the box body 7.

[0026] In this embodiment, the box body 7 serves as the main part of the purging mechanism, and its design makes the purging process more concentrated and effective. The box body 7 is fixed to the top of the chassis 1 to further remove residual moisture and impurities from the cleaned polishing brush; the hot air blower 8 serves as a device that provides purging power, and the hot air it generates can not only accelerate the evaporation of moisture, but also help to blow out residual impurities in the fibers of the polishing brush. Compared with cold air, the use of hot air can dry the polishing brush faster and improve production efficiency; the air pipe 9 serves as a component connecting the hot air blower 8 and the box body 7. Its design ensures the uniform distribution and effective transmission of hot air. By extending the air outlet end of the air pipe 9 into the box body 7, the hot air can be directly blown to the cleaned polishing brush to achieve purging.

[0027] In a further preferred embodiment of the utility model, the lifting mechanism includes: an assembly frame 16 that is arranged on the top of the shielding shell and can be moved laterally; an electric winch 12 fixed on the assembly frame 16; a rope 13 arranged on the electric winch 12; a hook 14 fixed on the rope 13; and a hanger 11 arranged on the hook 14, and the bottom end of the hanger 11 is fixedly connected to the placement seat 10.

[0028] In this embodiment, the assembly frame 16 is arranged in the shielding shell and has the ability to move laterally. This design enables the entire lifting mechanism to adjust its position in the horizontal direction so that the cleaned polishing brush can be moved into the box body 7 for subsequent blowing; the electric winch 12 is fixed on the assembly frame 16. As the power source of the lifting mechanism, it realizes the lifting function by rotating the rope 13. The hook 14 is fixed at the end of the rope 13 for hanging and fixing the hanger 11. The bottom end of the hanger 11 is fixedly connected to the placement seat 10, and the placement seat 10 can be hoisted.

[0029] In a further preferred embodiment of the utility model, a screw 15 for driving the assembly frame 16 to move is rotatably installed in the shielding shell, and the screw 15 is threadedly matched with the assembly frame 16.

[0030] In this embodiment, the screw 15 is designed to rotate in the shielding shell, and one end thereof passes through the assembly frame 16. This design allows the assembly frame 16 to be driven to move laterally in the shielding shell by the rotation of the screw 15. The rotational motion of the screw 15 is converted into the linear motion of the assembly frame 16, thereby achieving precise position adjustment; the motor 17 serves as a power source for the rotation of the screw 15, and its output shaft is fixedly connected to one end of the screw 15. By controlling the rotation direction and speed of the motor 17, the rotation of the screw 15 can be precisely controlled, thereby achieving precise control of the lateral movement speed and position of the assembly frame 16; the two ends of the guide rod 18 are fixedly connected to the shielding shell, and the assembly frame 16 is slidably mounted on the guide rod 18. This design ensures the stability and linearity of the assembly frame 16 during movement, and prevents the assembly frame 16 from deflecting or shaking during movement.

[0031] In a further preferred embodiment of the utility model, a filter box 19 is provided in the chassis 1 and is located below the drain pipe for collecting dirty liquid. A filter plate 20 is provided in the filter box 19.

[0032] In this embodiment, the filter box 19 is specially designed to receive the dirty liquid discharged from the drain pipe 4. This design can ensure that the dirty liquid is filtered before being discharged from the chassis 1 to reduce the impact on the environment. The filter plate 20 is the core component in the filter box 19, which is used to filter solid impurities in the dirty liquid. When the dirty liquid flows into the filter box 19, the filter plate 20 can intercept and remove the solid particles therein, so that the clean liquid passes through the filter plate 20 into the bottom of the filter box 19, while the solid impurities are retained above the filter plate 20. One end of the drain pipe 21 is connected to the bottom or side of the filter box 19, and the other end extends out of the chassis 1. The solid impurities and remaining liquid filtered by the filter plate 20 can be discharged from the chassis 1 through the drain pipe 21, which is convenient for subsequent processing.

[0033] In a further preferred embodiment of the utility model, a liquid injection pump 22 is fixedly installed in the chassis 1, and a liquid injection pipe 23 and a liquid supply pipe 24 are fixedly installed on the liquid outlet end and the liquid inlet end of the liquid injection pump 22 respectively, the liquid outlet end of the liquid injection pipe 23 is fixedly connected to the spray pipe 6, and the liquid supply pipe extends out of the chassis.

[0034] In this embodiment, the injection pump 22 serves as the core equipment for supplying the cleaning liquid. It is fixed in the chassis 1 to ensure the stability and reliability of the liquid supply. The injection pump 22 can accurately control the flow rate and flow rate of the cleaning liquid according to the preset cleaning program or the operator's instructions. One end of the injection pipe 23 is connected to the liquid outlet end of the injection pump 22, and the other end is fixedly connected to the spray pipe 6. The injection pipe 23 is responsible for transmitting the cleaning liquid output by the injection pump 22 to the spray pipe 6 to ensure that the cleaning liquid can be evenly sprayed on the polishing brush. One end of the liquid supply pipe 24 is connected to the liquid inlet end of the injection pump 22, and the other end is connected to the storage container or external supply system of the cleaning liquid. The function of the liquid supply pipe 24 is to provide the injection pump 22 with a steady supply of cleaning liquid to ensure the continuous cleaning process.
