Description

Technical Field

[0001] The invention relates to the field of graphene film cleaning, and in particular to an automatic graphene film processing cleaning device. Background Art

[0002] Graphene film is a material composed of single or multi-layer graphene sheets, which has excellent electrical conductivity, transparency, thermal conductivity and other properties, and is widely used in electronic devices, composite materials, biomedicine and other fields. In the processing of graphene film, in order to ensure the quality and performance of graphene film, it needs to be cleaned to remove impurities and stains on its surface, which is crucial to maintain the excellent physical and chemical properties of graphene film.

[0003] However, there are still the following problems in the process of cleaning graphene films: (1) Ultrasonic cleaning is commonly used to directly clean graphene films, but impurities with different adhesion strengths may adhere to the surface of the graphene film. Impurities with more stubborn adhesion are not easy to be removed, and the impurities removed first are suspended in the cleaning solution and may interfere with subsequent removal. The cleaning efficiency and cleaning quality need to be improved.

[0004] (2) In addition, single ultrasonic cleaning not only takes a long time to clean, but also is difficult to completely remove impurities and stains on the surface of the graphene film. The surface cleanliness of the graphene film is not ideal, and it is difficult to maintain uniform cleaning effects in different areas of the graphene film.

[0005] Therefore, in order to solve the problems existing in the cleaning process of the graphene film, the present invention provides an automatic cleaning device for graphene film processing. Summary of the invention

The small vacuum cleaner is connected to the suction holes of the corresponding rotating roller through suction pipes evenly arranged circumferentially on its left and right sides, and the suction pipes are embedded in the mounting plate.

[0012] In one possible implementation, guide assemblies are provided on the upper ends of the left and right sides of the ultrasonic cleaning tank, and two guide rollers distributed on the left and right are rotatably installed between the front and rear inner walls inside the ultrasonic cleaning tank. The guide assembly includes an arc-shaped plate arranged on the upper end of the ultrasonic cleaning tank, and a dust-free pad is detachably installed on the outer side of the arc-shaped plate.

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0032] See also Figure 1 A graphene film processing automated cleaning device comprises an ultrasonic cleaning pool 1, wherein a primary cleaning unit 2, a secondary cleaning unit 3 and a reel 4 for winding the graphene film are sequentially arranged on the left side, inside and right side of the ultrasonic cleaning pool 1, and the reel 4 is connected to an existing winding device, and an existing conveying device for conveying the graphene film is arranged on the left side of the primary cleaning unit 2 (the winding device and the conveying device are not shown in the figure).

[0033] See also Figure 1 , Figure 4 , Figure 8 and Fig. 9 The upper ends of the left and right sides of the ultrasonic cleaning tank 1 are provided with guide assemblies, and two guide rollers 111 distributed on the left and right are rotatably installed between the front and rear inner walls inside the ultrasonic cleaning tank 1. The guide assembly includes an arc-shaped plate 112 arranged at the upper end of the ultrasonic cleaning tank 1, and a dust-free pad is detachably installed on the outer side of the arc-shaped plate 112. Brackets fixedly connected to the outer side of the ultrasonic cleaning tank 1 are installed on the lower ends of the front and rear sides of the arc-shaped plate 112. Two movable plates 113 distributed front and back are slidably arranged on the outer side of the dust-free pad. Rollers 114 evenly arranged on the left and right are rotatably installed on the upper end of the movable plate 113. The side of the movable plate 113 away from the ultrasonic cleaning tank 1 is fixedly connected to the vertical section of the L-shaped plate, and a bidirectional threaded telescopic rod 115 rotatably connected to the corresponding horizontal section of the L-shaped plate is installed at the lower end of the arc-shaped plate 112.

[0034] During operation: the graphene film to be cleaned can be transported from left to right through the existing conveying equipment. During this process, the right end of the graphene film can be first pulled through the middle of the first-level cleaning unit 2, and then the graphene film reaching the upper left end of the ultrasonic cleaning tank 1 is pulled downward to the inside of the ultrasonic cleaning tank 1, and the graphene film is passed under the guide roller 111 on the left and moved to the right to under the guide roller 111 on the right, and then the graphene film is pulled upward to leave the ultrasonic cleaning tank 1, and then the graphene film is continued to be moved to the right to the position of the reel 4, and the graphene film can be wound up by the reel 4. Through the cooperation between the existing conveying equipment and the winding equipment, the graphene film can be continuously transported from left to right to complete the cleaning, and the winding equipment can continuously collect the cleaned graphene film through the reel 4. It should be noted that a gap is left between the inner wall of the ultrasonic cleaning tank 1 and the secondary cleaning unit 3 for convenient pulling of the graphene film.

[0035] In the process of the graphene film entering and leaving the ultrasonic cleaning tank 1, the arc plates 112 on the left and right sides are in contact with the corresponding graphene film segments through the dust-free pads. The arc plates 112 and the dust-free pads can be used to protect and support the transportation of the graphene film to avoid bending and damage of the graphene film during transportation. The dust-free pad can be removed and replaced with a new one after being used for a certain period of time. In addition, the graphene film is just located between the front and rear moving plates 113 outside the dust-free pad, and the rollers 114 at the upper end of the moving plates 113 can contact the graphene film during transportation. The rotating contact can limit and guide the graphene film while ensuring the smooth transportation of the graphene film. When graphene films of different widths need to be transported and cleaned, the telescopic ends of the bidirectional threaded telescopic rod 115 can be rotated to make the L-shaped plates on the front and rear sides drive the corresponding moving plates 113 and rollers 114 to move synchronously in the opposite direction along the arc plate 112 and the dust-free pad to the appropriate position, and the bidirectional threaded telescopic rods 115 on the left and right sides need to be adjusted to a consistent state. At the same time, a suitable reel 4 can be selected according to the width of the graphene film to roll up the cleaned graphene film.

[0036] See also Figure 1 , Figure 2 and Figure 3 The primary cleaning unit 2 includes two support plates 21 distributed front and back, and two groups of cleaning components distributed up and down are arranged between the front and rear support plates 21. The cleaning components include a rotating shaft 211 rotatably installed on the side where the front and rear support plates 21 are close to each other, and a turntable 212 is arranged on the side where the front and rear rotating shafts 211 are close to each other. A pulley 213 is installed on the turntable 212 located on the rear side, and a belt is connected between the upper and lower pulleys 213. A rotating column 214 is connected to the turntable 212 located on the front side, and circumferentially evenly arranged sockets 215 are opened on the outer side of the rotating column 214. A limiting rod 216 that is plugged and matched with the corresponding socket 215 is arranged between the upper and lower rotating columns 214.

[0037] See also Figure 2 and Figure 3 The outer ring surface of the turntable 212 is provided with mounting plates 217 that are evenly arranged in the circumferential direction, and a rotating roller 218 is rotatably installed between the front and rear opposite mounting plates 217 in a detachable manner. A dust sticking roller 219 is sleeved on the outside of the rotating roller 218, and evenly arranged air holes 221 are opened on the outside of the rotating roller 218 and the dust sticking roller 219. Suction holes are opened on the front and rear sides of the rotating roller 218, and a small vacuum cleaner 222 is arranged between the two front and rear opposite turntables 212. The small vacuum cleaner 222 is connected to the suction holes of the corresponding rotating roller 218 through suction pipes that are evenly arranged in the circumferential direction on its left and right sides, and the suction pipes are embedded in the mounting plate 217.

[0038] During operation: when the graphene film passes through the middle of the primary cleaning unit 2 from left to right, the graphene film is just located between the upper and lower cleaning components, and the upper surface of the graphene film contacts the sticky roller 219 located below in the upper cleaning component, and the lower surface of the graphene film contacts the sticky roller 219 located above in the lower cleaning component. As the graphene film is transported, the upper and lower sticky rollers 219 in contact with the graphene film drive the corresponding rotating rollers 218 to rotate accordingly. The rotating sticky rollers 219 can continuously remove impurities attached to the surface of the graphene film, so as to pre-roughly clean the graphene film before entering the ultrasonic cleaning tank 1, shorten the time for subsequent ultrasonic cleaning, and improve the cleaning effect and cleaning efficiency. In addition, the small vacuum cleaner 222 synchronously drives the suction pipe close to one side of the graphene film to work. Under the action of the suction holes on the front and rear sides of the corresponding rotating roller 218, the rotating roller 218 and the sticky roller 219 can use the evenly arranged pores 221 to further remove impurities attached to the surface of the graphene film.

[0039] After the sticky roller 219 rotates to clean a certain length of the graphene film, the cleaning component located on the top can be moved, and the turntables 212 on the front and rear sides respectively drive the corresponding rotating columns 214 and the pulleys 213 to rotate around the rotating point between the rotating shaft 211 and the support plate 21, and the rotating roller 218 and the sticky roller 219 rotate synchronously with the turntable 212 through the front and rear mounting plates 217, so that the sticky roller 219 and the rotating roller 218 that were originally in contact with the surface of the graphene film are rotated to a position away from the graphene film. At this time, the unused sticky roller 219 and the rotating roller 218 are rotated to the position of contacting with the graphene film. In addition, with the cooperation of the pulleys 213 and the belts in the upper and lower cleaning components, the lower cleaning component rotates synchronously with the upper cleaning component, and changes the positions of the sticky roller and the rotating roller 218 in the same way. After the upper and lower cleaning components of the two groups are rotated to the appropriate positions, the limiting rods 216 can be simultaneously inserted into the corresponding sockets 215 on the upper and lower rotating columns 214, and the upper and lower rotating columns 214 can be limited at the same time, which can effectively fix the cleaning components and prevent the cleaning components from rotating when the sticky roller 219 cleans the surface of the graphene film and affecting the cleaning effect.

[0040] Then the used rotating roller 218 and sticky roller 219 can be removed from between the front and rear mounting plates 217 so as to clean the impurities adsorbed on the rotating roller 218 and the sticky roller 219. Subsequently, the cleaned rotating roller 218 and the sticky roller 219 can be installed between the front and rear mounting plates 217 again. By intermittently rotating the upper and lower groups of cleaning components, the rotating roller 218 and the sticky roller 219 evenly arranged circumferentially can be used to continuously adsorb and clean the surface of the graphene film, which can not only ensure that the sticky roller 219 always maintains a good adhesion state, making the cleaning effect of different sections of the graphene film uniform and consistent, but also ensure the continuity of the cleaning process, thereby improving the cleaning efficiency.

[0041] See also Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The secondary cleaning unit 3 includes two groups of scrubbing components located between the left and right guide rollers 111 and distributed up and down. The scrubbing components include a grid plate 311 connected to the front and rear inner walls of the ultrasonic cleaning tank 1 for sliding up and down. Both the front and rear sides below the grid plate 311 are provided with transverse guide rails 312. Both the front and rear sides of the bottom wall of the ultrasonic cleaning tank 1 are provided with two guide rods 313 distributed left and right. Two guide blocks 314 connected to the corresponding guide rods 313 for sliding up and down are installed on the side of the transverse guide rail 312 away from the center of the ultrasonic cleaning tank 1. The front and rear transverse guide rails 312 are close to each other. Two sliding blocks 315 are installed on one side for sliding left and right, and a wiping sponge plate 316 is detachably installed between the two sliding blocks 315 facing each other. Connectors for connecting the upper and lower groups of scrubbing components are provided on the front and rear inner walls of the ultrasonic cleaning tank 1. A driving component for driving the grid plate 311 and the transverse guide rail 312 in the same group of scrubbing components to move synchronously in the opposite direction is provided above the ultrasonic cleaning tank 1. Control components for controlling the corresponding two sliding blocks 315 to move synchronously in the opposite direction along the transverse guide rail 312 are provided above the two transverse guide rails 312 located on the front side.

[0042] See also Figure 1 , Figure 4 , Figure 5 and Figure 7The distance between the front and rear transverse guide rails 312 in the upper scrubbing assembly is smaller than the distance between the front and rear transverse guide rails 312 in the lower scrubbing assembly. The upper and lower grid plates 311 are provided with avoidance grooves 317 for avoiding the corresponding transverse guide rails 312, the wiping sponge plate 316, the connecting member and the control assembly. The connecting member includes two rotating gears 318 rotatably mounted on the inner wall of the ultrasonic cleaning tank 1 and distributed on the left and right sides. The left and right sides of the rotating gear 318 are meshed with racks 319 connected to the inner wall of the ultrasonic cleaning tank 1 in an upward and downward sliding manner. The rack 319 located on the side away from the left and right rotating gears 318 is fixedly connected to the upper and lower grid plates 311, and the rack 319 located on the side close to the left and right rotating gears 318 is fixedly connected to the upper and lower transverse guide rails 312. The driving assembly includes an inverted plate 321 installed on the upper end of the upper grid plate 311, and the middle part of the upper end of the horizontal section of the inverted plate 321 is connected to the pushing end of the cylinder 322. An inverted support 323 with a horizontal section fixedly connected to the fixed section of the cylinder 322 is connected between the upper ends of the front and rear sides of the ultrasonic cleaning tank 1.

[0043] During operation: in the initial state, the wiping sponge plates 316 and the transverse guide rails 312 in the upper and lower scrubbing assemblies are both located in the avoidance grooves 317 on the corresponding grid plates 311, and the upper and lower scrubbing assemblies are both located away from the graphene film so that the graphene film can be smoothly transported. When the graphene film enters the ultrasonic cleaning tank 1 and is located between the upper and lower scrubbing assemblies, the transport of the graphene film is suspended, and the ultrasonic cleaning tank 1 starts to work to ultrasonically clean the graphene film, and a cleaning liquid for cleaning the graphene film is placed in the ultrasonic cleaning tank 1. Subsequently, the inverted plate 321 and the upper grid plate 311 can be driven upward by the cylinder 322, and the upper grid plate 311 drives the corresponding rack 319 to move upward synchronously along the inner wall of the ultrasonic cleaning tank 1, and the lower grid plate 311 is driven by the gear rack 319 to move upward synchronously along the inner wall of the ultrasonic cleaning tank 1. The rack 319 moves up synchronously with the grid plate 311 above. At this time, the rotating gear 318 on the left rotates clockwise, and the rotating gear 318 on the right rotates counterclockwise. The two racks 319 on the side close to the left and right rotating gears 318 move downward synchronously along the inner wall of the ultrasonic cleaning tank 1. The transverse guide rails 312 on the upper and lower sides move downward with the corresponding racks 319. The transverse guide rails 312 drive the wiping sponge plate 316 to move downward synchronously through the sliding block 315. During this process, the transverse guide rails 312 drive the guide blocks 314 on the left and right sides to move downward along the corresponding guide rods 313. The cooperation between the guide rods 313 and the guide blocks 314 can support and guide the movement of the transverse guide rails 312, thereby increasing the stability of the transverse guide rails 312, the sliding block 315 and the wiping sponge plate 316 during the movement.

[0044] As the grid plate 311 moves upward, the transverse guide rail 312 and the wiping sponge plate 316 move downward until the grid plate 311 at the bottom is in contact with the lower surface of the graphene film, and the wiping sponge plate 316 at the top is in contact with the upper surface of the graphene film. Since the graphene film is relatively soft, the grid plate 311 in contact with the graphene film can support and solidify the graphene film to avoid damage and deformation of the graphene film when the subsequent wiping sponge plate 316 wipes the graphene film. At this time, the grid plate 311 at the top and the wiping sponge plate 316 and the transverse guide rail 312 at the bottom are all in a position away from the graphene film. During this process, the control component moves downward synchronously with the corresponding transverse guide rail 312.

[0045] See also Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The control component includes a connecting rod 324 hinged at the upper end of the side away from the left and right adjacent sliding blocks 315 located on the front side, and the other end of the left and right adjacent connecting rods 324 is hinged to the same pushing block 325. A clamping block 326 is installed on the upper end of the pushing block 325, and an inverted T-shaped slot is provided on the clamping block 326. A sliding groove is provided on the front side of the horizontal section of the inverted C-shaped support 323. A moving block 327 is installed inside the sliding groove for forward and backward sliding. The moving block 327 is fixedly mounted on the outside of the fixed section of the electric push rod 328, and an I-shaped block 329 matching the corresponding inverted T-shaped slot is installed at the lower end of the pushing end of the electric push rod 328.

[0046] During operation: after the lower grid plate 311 and the upper wiping sponge plate 316 come into contact with the graphene film, the upper surface of the graphene can be wiped and cleaned by the wiping sponge plate 316. Since the distance between the front and rear transverse guide rails 312 located at the top is smaller than the distance between the front and rear transverse guide rails 312 located at the bottom, the control components on the two front transverse guide rails 312 do not affect each other. In this process, the moving block 327 and the electric push rod 328 can be pushed backward along the sliding groove, and the electric push rod 328 drives the I-shaped block 329 to move backward synchronously until the I-shaped block 329 is inserted into the inverted T-shaped slot in the upper control component. In the initial state, the moving block 327 and the electric push rod 328 are at the frontmost side of the sliding groove, and the electric push rod 328 and the I-shaped block 329 will not interfere with the up and down movement of the control component. After the I-shaped block 329 is inserted into the inverted T-shaped slot, the electric push rod 328 can push the I-shaped block 329, the card block 326 and the push rod 328 The movable block 325 moves downward, and while the pushing block 325 moves downward, the connecting rods 324 on the left and right sides rotate synchronously in opposite directions around the hinge points between them and the pushing block 325, and the corresponding left and right sliding blocks 315 slide synchronously in opposite directions along the transverse guide rail 312 with the corresponding connecting rods 324, and the wiping sponge plate 316 moves synchronously along the upper surface of the graphene with the corresponding sliding block 315. After the wiping sponge plate 316 moves to a position close to the guide roller 111, the electric push rod 328 can be used to drive the I-block 329, the card block 326 and the pushing block 325 to move up and reset, and the connecting rod 324, the sliding block 315 and the wiping sponge plate 316 are synchronously reset to the initial state. In this process, the left and right wiping sponge plates 316 wipe the upper surface of the graphene film back and forth to clean it. In combination with ultrasonic cleaning, the stubborn impurities and stains on the upper surface of the graphene film can be further cleaned, thereby further improving the surface cleanliness of the graphene film.

[0047] After the upper surface of the graphene film is cleaned, the moving block 327 and the electric push rod 328 can be moved forward along the sliding groove to reset, so that the I-shaped block 329 is disengaged from the inverted T-shaped groove, and then the grid plate 311 located above is pushed downward by the cylinder 322. Under the cooperation of the rack 319 and the rotating gear 318, the grid plate 311 located above moves downward to fit the upper surface of the graphene film, and the transverse guide rail 312 located below drives the wiping sponge plate 316 to move upward to contact the lower surface of the graphene film. The upper transverse guide rail 312 and the wiping sponge plate 316 pass through the avoidance groove 317 on the upper grid plate 311 and move upward relatively. 16 passes through the avoidance groove 317 on the lower grid plate 311 and moves upward. At this time, the control component can move upward synchronously with the corresponding transverse guide rail 312, and then the I-block 329 can be pushed down to a position flush with the block 326 in the lower control component through the electric push rod 328. Then, the moving block 327 and the electric push rod 328 can be moved along the sliding groove to make the I-block 329 snap into the corresponding inverted T-shaped slot. Then, the left and right wiping sponge plates 316 located below can be controlled in the same way as above to wipe and clean the lower surface of the graphene film. After the wiping sponge plate 316 has been used for a certain period of time, it can be removed from between the front and rear sliding blocks 315 and replaced with a new wiping sponge plate 316.

[0048] After the upper and lower surfaces of the graphene film are wiped and cleaned, the upper and lower wiping components and the control components can be reset, and then the conveying device and the winding device can continue to convey it to the right, so that the cleaned graphene film segment moves away from the ultrasonic cleaning tank 1, and the uncleaned graphene film segment moves between the left and right guide rollers 111. Subsequently, the graphene film segment located between the left and right guide rollers 111 can be wiped and cleaned in the same manner as described above.

Two vertical panels 334 symmetrically arranged in an upper and lower direction are connected between the front and rear upright posts 333. The sides of the upper and lower vertical panels 334 close to each other are both detachably installed with dust-free cotton blocks 335. The lower vertical panel 334 is fixedly connected to the upright post 333, and the upper vertical panel 334 is slidably connected to the upright post 333 up and down. A connecting spring 336 sleeved on the outside of the upright post 333 is connected between the upper and lower vertical panels 334.

[0050] During operation: after the cleaned graphene film leaves the ultrasonic cleaning tank 1, the graphene film can be pulled to pass between the upper and lower longitudinal plates 334, and the lower longitudinal plate 334 is in contact with the lower surface of the graphene film through the dust-free cotton block 335 at its upper end. Under the action of the connecting spring 336, the upper longitudinal plate 334 is in elastic contact with the upper surface of the graphene film through the dust-free cotton block 335 at its lower end. The dust-free cotton blocks 335 on the upper and lower sides can further wipe off the moisture and other impurities attached to the upper and lower surfaces of the graphene film. After the dust-free cotton blocks 335 have been used for a certain period of time, the upper longitudinal plate 334 can be moved along the front and rear columns 333 to move up and away from the graphene film. Then, the upper and lower dust-free cotton blocks 335 can be removed from the corresponding longitudinal plates 334 after use and replaced with new dust-free cotton blocks 335 to maintain the good cleaning effect of the dust-free cotton blocks 335.
