Description

Technical Field

[0001] This invention relates to the field of electrolytic copper foil production equipment, and more particularly to a polishing brush cleaning device and its usage method. Background Technology

[0002] With the rapid development of electronic information technology, customers have increasingly higher requirements for the quality of lithium battery copper foil. In the electrolytic copper foil production process, copper ions first adhere to the surface of the cathode roller to form copper foil. Therefore, the surface roughness of the cathode roller directly affects the quality of the copper foil. Currently, in the industry, the surface roughness requirement for the cathode roller in the production of ultra-thin lithium battery copper foil is Ra<0.2. There are two types of grinding for the cathode roller: offline grinding and online grinding. Offline grinding involves using a grinding machine with a grinding wheel to grind the cathode roller. The surface roughness of the cathode roller after offline grinding generally meets the requirements, but it is time-consuming. Offline grinding is only used when online grinding fails to meet the requirements. Online grinding rollers use a polishing machine on a foil-making machine to polish the cathode roller with a polishing brush. This type of grinding roller does not require removing the cathode roller. The quality of the polishing brush determines the surface roughness of the cathode roller. The polishing brush is a type of brush made of non-woven fabric. There are gaps at the bonding points. During the grinding process or before use, dust and other impurities from the polishing process can easily remain in the gaps between the polishing brushes. If these impurities are not cleaned in time, they can easily scratch the cathode roller during online grinding, thus affecting the quality of the electrolytic copper foil and causing losses. Therefore, a cleaning device is needed to clean the polishing brush after grinding.

[0003] Existing methods for cleaning polishing brushes include removing them from the polishing machine and rinsing them in warm water with a brush, or placing them in an ultrasonic cleaner for ultrasonic cleaning. However, neither of these methods can effectively remove impurities remaining in the gaps between the polishing brushes. Summary of the Invention

[0004] The problem this invention aims to solve is that impurities remaining in the gaps between existing polishing brushes are difficult to remove efficiently. To address this, an automatic polishing brush cleaning device and its usage method are provided.

[0005] The technical solution of the present invention is: an automatic cleaning device for polishing brushes, comprising: a frame; a water tank installed on the top of the frame; a drive mechanism installed on the top of the frame and near one end of the water tank; a bearing seat adjustment mechanism installed on the top of the frame and located between the drive mechanism and the bearing seat adjustment mechanism; a polishing brush, one end of which is connected to the drive mechanism via a coupling, the coupling being installed on the bearing seat adjustment mechanism; and an ultrasonic generator installed on the inner wall of the bottom of the water tank.

[0006] The improvement to the above solution is that the top of the water tank is open, and a protective cover that can cover the top of the water tank is hinged to one side of the water tank. An opening groove is opened in the center of the protective cover along the length direction. A linear moving mechanism is slidably fitted on the opening groove. A fixed seat extends outward from the linear moving mechanism. A through hole is opened on the fixed seat. A negative pressure pipe that extends into the opening groove is connected in the through hole. Sliding grooves extending along the length direction of the water tank are opened on the inner walls of both sides of the water tank. A slider is slidably fitted in the sliding groove. An arc-shaped cover located above the polishing brush is hinged to the outside of the slider. An air extraction hole is opened on the arc-shaped cover. The air extraction hole is detachably connected to the negative pressure pipe. The inner wall of the arc-shaped cover is provided with brush bristles.

[0007] The driving mechanism described in the above scheme includes: a first linear guide rail located at the top of the frame, the extension direction of the first linear guide rail being consistent with the length direction of the water tank, a motor mounting plate slidably fitted on the first linear guide rail, a drive motor mounted on the motor mounting plate, a coupling connected to the drive motor, and the coupling being connected to the coupling of the polishing brush.

[0008] The bearing housing adjustment mechanism described in the above scheme includes: a cylinder installed on the top of the frame, two second linear guide rails on both sides of the cylinder, a mounting plate slidably fitted on the two second linear guide rails, the bottom of the mounting plate being fixedly connected to the piston rod of the cylinder, and a bearing housing for mounting a coupling for a polishing brush being installed on the top of the mounting plate.

[0009] A further improvement to the above solution is that a drain pipe is connected to the lower side of the water tank, and a water inlet pipe is connected to the upper side of the water tank.

[0010] Another improvement to the above scheme is that the water tank is equipped with vertically distributed overflow pipes.

[0011] Another improvement to the above scheme is that the bottom of the frame is equipped with Fuma wheels.

[0012] A method for using an automatic polishing brush cleaning device includes the following steps: removing the polishing brush from the polishing machine and placing it into a bearing seat adjustment mechanism so that the coupling of the polishing brush is placed in the bearing seat adjustment mechanism, the coupling being connected to the drive mechanism; injecting cleaning agent into a water tank until partially submerging the polishing brush; starting the drive mechanism to rotate the polishing brush in the water tank; and simultaneously starting an ultrasonic generator to clean the polishing brush.

[0013] Another method for using an automatic polishing brush cleaning device includes the following steps: Remove the polishing brush from the polishing machine and place it into the bearing seat adjustment mechanism, so that the polishing brush coupling is placed inside the bearing seat adjustment mechanism. The coupling is connected to the drive mechanism. A protective cover is placed on top of the water tank. Cleaning agent is injected into the water tank until it partially submerges the polishing brush. The drive mechanism is started, causing the polishing brush to rotate within the water tank. Simultaneously, the ultrasonic generator is activated to clean the polishing brush. During the cleaning process, a linear motion mechanism is activated to move back and forth within the open slot, drawing air into the negative pressure pipe. The linear motion mechanism, through the negative pressure pipe, drives the arc-shaped cover to move back and forth along the upper surface of the polishing brush. During this period, cleaning agent overflows onto the upper surface of the polishing brush, cleaning its surface.

[0014] The beneficial effects of this invention are: the use of a two-in-one cleaning mode combining ultrasonic cleaning and polymer cleaning agent results in more thorough cleaning; the automatic polishing brush cleaning device has a simple structure, convenient transfer of the fuma wheel, and a stainless steel body that is corrosion-resistant; the cleaned polishing brush effectively reduces polishing brush marks and "bright lines" on the cathode roller, lowers the roughness of the cathode roller, improves the quality of copper foil, extends the interval between polishing brush dressing and grinding, significantly increases the service life of the polishing brush, reduces the time spent on each polishing, reduces the waste of copper foil after polishing, and improves production efficiency; the linear movement mechanism combined with the negative pressure pipe allows the cleaning fluid to cover the upper part of the polishing brush that is not soaked, while simultaneously driving the arc-shaped cover to move back and forth on the upper surface of the polishing brush, improving cleaning efficiency, shortening cleaning time, and minimizing damage to the brush bristles.

Implementation

[0023] The invention will now be further described with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, an automatic polishing brush cleaning device includes a frame 1, a protective cover 2, a water tank 3, a control panel 4, a drive mechanism 5, a bearing seat adjustment mechanism 6, a polishing brush 7, an ultrasonic generator 8, a drain pipe 9, a water inlet pipe 10, an overflow pipe 11, and a fuma wheel 12. The frame is a rectangular main body welded from square tubing and steel plates, and an electrical cabinet is installed inside the frame. The fuma wheel is located at the base of the frame. The water tank, a rectangular structure welded from profiles, is mounted on the frame. The protective cover, made of transparent PVC material, is hinged to the water tank via pins and has a shape that is higher in the middle and lower on both sides. The control panel is located on the frame.

[0025] The drive mechanism includes a drive motor 51, a motor mounting plate 52, a first linear guide rail 53, and a coupling 54. The drive mechanism is mounted on the frame and directly connected to the polishing brush to be cleaned. The drive motor is mounted on the motor mounting plate, the coupling is mounted on the drive motor shaft, the motor mounting plate is mounted on the first linear guide rail, and the first linear guide rail is mounted on the frame. The drive mechanism can move back and forth along the first linear guide rail to adjust the position of the drive motor.

[0026] The bearing housing adjustment mechanism includes a bearing housing 61, a mounting plate 62, a second linear guide rail 63, and a cylinder 64. The bearing housing adjustment mechanism is mounted on a frame, the bearing housing is mounted on the mounting plate, the mounting plate is mounted on the second linear guide rail, and the cylinder is mounted on the frame and connected to the mounting plate via a piston rod. The second linear guide rail is mounted on the frame. The bearing housing adjustment mechanism can move the position of the cylinder back and forth along the second linear guide rail.

[0027] The polishing brush is a module disassembled from the polishing machine and connected to the drive mechanism. The ultrasonic generator is installed at the bottom of the water tank, and the drain pipe, inlet pipe, and overflow pipe are located inside the water tank. The drive mechanism and its adjustment mechanism can be electrically controlled for real-time one-button start-up, ensuring successful cleaning on the first attempt. The ultrasonic cleaning combined with a polymer cleaning agent provides a two-in-one cleaning mode for a more thorough cleaning.

[0028] In the above solution, it was found that although the polishing brush can rotate, because the water level in the tank cannot completely submerge the polishing brush, a portion of the brush is always exposed outside the cleaning agent. Furthermore, the ultrasonic generator at the bottom of the tank cannot effectively reach the polishing brush. Even if the brush is rotated continuously to compensate for this deficiency, it takes longer and cannot guarantee complete cleaning of any adhering impurities inside the brush. Therefore, a preferred embodiment of the present invention is proposed: the top of the tank is open, and a protective cover 2 is hinged to one side of the tank to cover the top. An opening groove is formed in the center of the protective cover along its length. A linear moving mechanism 13 is slidably fitted onto the opening groove. A fixed base 14 extends outward from the linear moving mechanism. A through hole 15 is formed on the fixed base, and a negative pressure pipe 16 extending into the opening groove is connected to the through hole. The negative pressure pipe is connected to an external air extraction device via a flexible hose. Sliding grooves 17 extending along the length of the tank are formed on the inner walls of both sides of the tank, and sliding mechanisms are slidably fitted into these grooves. The slider has an arc-shaped cover 18 hinged to its outer side above the polishing brush. To avoid the arc-shaped cover affecting the installation of the polishing brush, the slider and the arc-shaped cover are detachable, for example, with a locking ring structure. Alternatively, a groove can be provided on the inner wall of one side of the water tank. The arc-shaped cover has an air extraction hole, which is detachably connected to a negative pressure pipe, for example, with a threaded connection. The negative pressure pipe and the through hole can also be threaded, facilitating the adjustment of the distance the negative pressure pipe extends into the water tank, thereby adjusting the distance between the arc-shaped cover and the polishing brush. The inner wall of the arc-shaped cover is provided with bristles (not shown in the figure). The linear movement mechanism can be a linear motor, an electric push rod, an electric cylinder, etc. The advantage of this structure is that it can periodically clean the upper surface of the polishing brush. The negative pressure generated by the negative pressure pipe adsorbs the cleaning agent onto the upper surface of the polishing brush, while the arc-shaped cover moves back and forth relative to the polishing brush, removing stubborn impurities hidden inside the polishing brush, shortening the cleaning time, and improving cleaning efficiency.
