Description

Technical Field

[0001] This application relates to the technical field of pole piece coating equipment, and in particular to a cleaning device and a coating system. Background Art

[0002] With the development of the new energy industry, lithium batteries have become a research hotspot. In particular, blade batteries have advantages such as high energy density, high safety performance, and long life, and are favored by consumers. The current main production processes of blade batteries include sheet making, assembly, inspection, and packaging. Among them, sheet making mainly involves uniformly coating a slurry or ceramic mixed according to a ratio on a pole piece through a coater.

[0003] For example, the coater includes a climbing roller. The climbing roller is used to transport the pole piece and coat the pole piece during the transportation process. According to the process requirements, one side is coated first. After the coating on one side is baked and shaped by the first-layer oven, the other side is coated, and under the action of the climbing roller, the coating on the other side is transported to the second-layer oven. When the coating on the other side is baked and shaped, the coating of the entire sheet making is completed.

[0004] However, during the coating process, there is a phenomenon that the climbing roller adheres to the slurry or ceramic. Currently, operators use lint-free cloth to manually clean the climbing roller, which not only poses safety hazards, but also has low cleaning efficiency and poor cleaning effect.

[0066] In the related art, during the production and coating process of blade batteries, the climbing roller has the phenomenon of adhering slurry or ceramics, and the climbing roller needs to be cleaned. Currently, operators use dust-free cloth for manual cleaning, which has potential safety hazards, and the cleaning efficiency is low and the effect is poor. After research by the inventor, it is found that the reason for this problem is:

[0067] In the related art, operators use lint-free cloth to clean the climbing rollers, which is time-consuming and laborious, and the cleaning efficiency and effect are poor; moreover, since the climbing rollers are at a certain height from the ground, there are safety hazards; during the cleaning process, the coating machine needs to be shut down, affecting production capacity; and during the cleaning process, some foreign objects cannot be effectively collected and fall on the lower anode plates, which is likely to cause anode plate contamination or damage and affect the quality of anode plate production.

[0068] In view of the above technical problems, the embodiment of the present application provides a cleaning device. By arranging the second driving mechanism on the first driving mechanism, the telescopic direction of the first driving shaft of the first driving mechanism is consistent with the axial direction of the climbing roller, the telescopic direction of the second driving shaft of the second driving mechanism is perpendicular to the axial direction of the climbing roller, and a cleaning component is arranged at the end of the second driving shaft. When the climbing roller needs to be cleaned, the first driving mechanism and the second driving mechanism can be controlled to act, and the outer peripheral wall of the climbing roller can be cleaned by using the cleaning component. The foreign objects after cleaning can be collected into the collection component.

[0069] With such a setting, the cleaning device provided by the embodiment of the present application can automatically clean the outer peripheral wall of the climbing roller based on the first driving mechanism and the second driving mechanism, without the operator standing at a high position to clean the climbing roller, which can reduce safety hazards, improve cleaning efficiency and cleaning effect at the same time; and there is no need to shut down during the cleaning process, which can improve production capacity. Further, during the cleaning process, the collection component is used to effectively collect foreign objects, which can reduce the risk of foreign objects falling on the lower anode plates and improve the quality of anode plate production.

[0070] In order to make the above objects, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present application.

[0071] To facilitate the description of the embodiments of the present application, the coordinate system of the accompanying drawings is first described. The X-axis is the first direction, and the first direction can be the telescopic direction of the first driving shaft, which is consistent with the axial direction of the climbing roller; the Y-axis direction is the second direction, and the second direction is the telescopic direction of the second driving shaft; the Z-axis direction is the third direction, and the third direction can be the height direction.

[0072] As Figure 1 and Figure 2As shown in the figure, the coating system 100 provided by the embodiment of the present application is used for coating the workpiece to be coated. In this embodiment, the workpiece to be coated can be a strip-shaped electrode 30. For example, the strip-shaped electrode 30 includes, but is not limited to, copper foil or aluminum foil. The coating system 100 coats slurry or ceramic on the strip-shaped electrode 30 and forms a coating. The coating can be evenly laid on the first side and the second side of the strip-shaped electrode 30. After the coating is shaped, a strip-shaped film is formed, thereby completing the production of the blade battery.

[0073] Specifically, the coating system 100 includes a first oven 50, a second oven 60, a guide roller 70, a bracket 40, at least one climbing roller 20, and a cleaning device 10. The first oven 50 and the second oven 60 are arranged at intervals along the third direction. For example, the second oven 60 is arranged on the top of the first oven 50 along the third direction.

[0074] According to the requirements of the production process, during the coating process of the strip-shaped electrode 30, the first side of the strip-shaped electrode 30 needs to be coated to form a first coating. After the first coating is dried and shaped in the first oven 50, the second side of the strip-shaped electrode 30 is coated to form a second coating, and the second coating needs to be transferred to the second oven 60 for drying and shaping.

[0075] For example, a first coating device is arranged at the inlet of the first oven 50 to coat the strip-shaped electrode 30 and form a first coating. At this time, driven by the transmission roller, the first coating enters the first oven 50 for baking and shaping.

[0076] The strip-shaped electrode 30 moves out of the outlet of the first oven 50 and continues to move horizontally. Under the action of the guide roller 70, one end of the strip-shaped electrode 30 is flipped from the horizontal direction and moves obliquely upward. A second coating device is arranged near the guide roller 70, which can coat the second side of the strip-shaped electrode 30 and form a second coating.

[0077] The second coating moves obliquely upward following the strip-shaped electrode 30. Of course, during this upward movement, the climbing roller 20 drives the strip-shaped electrode 30 to move obliquely upward. In the embodiment of the present application, the climbing roller 20 is arranged on the bracket 40 and rotates relative to the bracket 40 to transmit the strip-shaped electrode 30 so that the strip-shaped electrode 30 enters the second oven 60 after climbing.

[0078] It should be noted that the bracket 40 is located on one side of the first oven 50 and the second oven 60 to avoid the bracket 40 interfering with the transmission of the strip-shaped electrode 30. And during the climbing stage of the strip-shaped electrode 30, the first coating contacts the climbing roller 20. Therefore, when the first coating is not completely shaped, there is a phenomenon that the climbing roller 20 adheres to the slurry or ceramic, and the foreign matter on the climbing roller 20 needs to be cleaned to ensure the production quality.

[0079] The cleaning device 10 provided in the embodiment of the present application is installed on the bracket 40 and is disposed close to the climbing roller 20. The cleaning device 10 can clean the foreign matters on the outer peripheral wall of the climbing roller 20, that is, the cleaning device 10 is disposed close to the workpiece to be cleaned, and the cleaning device 10 can clean the foreign matters on the outer peripheral wall of the workpiece to be cleaned.

[0080] It can be understood that the workpiece to be cleaned includes, but is not limited to, the climbing roller, and can also be other rollers that need to be cleaned, such as the guide roller 70 of the coating system, etc. The embodiment of the present application does not limit this. Hereinafter, the cleaning of the climbing roller 20 by the cleaning device will be taken as an example for description.

[0081] Specifically, as Figures 3 to 5 shown, the cleaning device 10 includes a first driving mechanism 11, a second driving mechanism 12, a cleaning component 13 and a collecting component 14. The first driving mechanism 11 is installed on the bracket 40 and is located on one side of the climbing roller 20, that is, the first driving mechanism 11 is disposed close to the workpiece to be cleaned.

[0082] The second driving mechanism 12 is installed on the first driving mechanism 11, and the cleaning component 13 is disposed on the second driving mechanism 12. Under the action of the first driving mechanism 11, the cleaning component 13 can clean the foreign matters on the surface of the climbing roller 20. During the cleaning process, the collecting component 14 is used to effectively collect the foreign matters.

[0083] Exemplarily, the first driving mechanism 11 includes a first driving motor 111 and a first driving shaft 112. The first driving motor 111 is in transmission connection with the first driving shaft 112, and the first driving motor 111 can drive the first driving shaft 112 to extend and retract. The extending and retracting direction of the first driving shaft 112 is the same as the first direction, that is, the first driving shaft 112 moves along the axial direction parallel to the climbing roller 20.

[0084] The second driving mechanism 12 is disposed at the end of the first driving shaft 112. The second driving mechanism 12 includes a second driving motor 121 and a second driving shaft 122. The second driving motor 121 is in transmission connection with the second driving shaft 122, and the second driving motor 121 can drive the second driving shaft 122 to extend and retract. The extending and retracting direction of the second driving shaft 122 is the same as the second direction, and the second direction is perpendicular to the first direction, that is, the extending and retracting direction of the second driving shaft 122 is perpendicular to the axial direction of the climbing roller 20. For example, the first driving shaft 112 and the second driving shaft 122 are located in the same horizontal plane.

[0085] The cleaning component 13 is disposed at the end of the second driving shaft 122 and is disposed close to the climbing roller 20. When cleaning the foreign matters on the surface of the climbing roller 20, the cleaning component 13 contacts the outer peripheral wall of the climbing roller 20, that is, the cleaning component 13 rubs against the outer peripheral wall of the climbing roller 20 to remove the foreign matters. The cleaning component 13 includes, but is not limited to, a scraping blade, a dust-free cloth, a grinding sheet, etc.

[0086] The collecting component 14 is arranged below the cleaning component 13 along the third direction. The collecting component 14 is configured to move synchronously with the cleaning component 13 during the process of the cleaning component 13 cleaning the outer peripheral wall of the climbing roller, so that the collecting component 14 always remains below the cleaning component 13 during the cleaning process, and the collecting component 14 can effectively collect the foreign matters to be cleaned.

[0087] For example, in one embodiment, the collecting component 14 is installed at the end of the first driving shaft 112, and the collecting component 14 extends below the cleaning component 13. When the first driving shaft 112 reciprocates axially relative to the climbing roller 20 and the cleaning component 13 cleans the outer peripheral wall of the climbing roller, the collecting component 14 can move synchronously with the cleaning component 13, that is, the collecting component 14 and the cleaning component 13 are relatively stationary, and the collecting component 14 can collect the foreign matters to be cleaned.

[0088] In another embodiment, the collecting component 14 is installed at the end of the second driving shaft 122, and the collecting component 14 is located below the cleaning component 13. Since the second driving mechanism is installed at the end of the first driving shaft 112. When the first driving shaft 112 reciprocates axially relative to the climbing roller 20 and the cleaning component 13 cleans the outer peripheral wall of the climbing roller 20, the collecting component 14 can move synchronously with the cleaning component 13, that is, the collecting component 14 and the cleaning component 13 are relatively stationary, and the collecting component 14 can collect the foreign matters to be cleaned.

[0089] In the related art, operators use dust-free cloth to clean the climbing roller, and the cleaning efficiency and cleaning effect are poor; moreover, since the climbing roller is at a certain height from the ground, there are safety hazards; during the cleaning process, the coating machine needs to be shut down, affecting production capacity; and during the cleaning process, some foreign matters cannot be effectively collected and fall on the lower pole piece, which is likely to cause pole piece pollution or damage and affect the quality of pole piece production.

[0090] However, the cleaning device 10 provided by the embodiments of the present application can automatically clean the outer peripheral wall of the climbing roller 20 based on the first driving mechanism 11 and the second driving mechanism 12. Therefore, there is no need for operators to stand at a high position to clean the climbing roller 20, which can reduce safety hazards, and at the same time improve the cleaning efficiency and cleaning effect; and there is no need to shut down during the cleaning process, which can improve production capacity. Further, during the cleaning process, the collecting component 14 is used to effectively collect foreign matters, which can reduce the risk of foreign matters falling on the lower pole piece and improve the quality of pole piece production.

[0091] Based on the above embodiments, to facilitate the installation of the cleaning component 13 at the end of the second drive shaft 122, the cleaning device 10 provided in the embodiments of the present application further includes a carrier plate. For the convenience of describing the embodiments, this carrier plate can be defined as the second carrier plate 17, and the second carrier plate 17 is used to carry the cleaning component 13.

[0092] As Figure 6 shown, the second carrier plate 17 is disposed at the end of the second drive shaft 122 facing the climbing roller 20. For example, the second carrier plate 17 is fixedly connected to the end of the second drive shaft 122 or detachably connected to the end of the second drive shaft 122. Of course, the cleaning component 13 can also be directly installed at the end of the second drive shaft 122 as needed, and the embodiments of the present application do not limit this. As follows, unless otherwise specified, the embodiments of the present application will take the second carrier plate 17 being disposed at the end of the second drive shaft 122 and the cleaning component 13 being installed on the second carrier plate 17 as an example for description.

[0093] The cleaning component 13 provided in the embodiments of the present application includes a grinding sheet 131, and the grinding sheet 131 is detachably installed at the end of the second drive shaft 122. For example, the grinding sheet 131 extends in the second direction, one end of the grinding sheet 131 is detachably installed on the second carrier plate 17 and is perpendicular to the second carrier plate 17; the other end of the grinding sheet 131 is disposed close to the climbing roller 20, and when cleaning the outer peripheral wall of the climbing roller 20, the end of the grinding sheet 131 can contact the outer peripheral wall of the climbing roller 20.

[0094] The cleaning component 13 provided in the embodiments of the present application further includes a fixing block 132 and a pressing movable block 133. The fixing block 132 is fixed to the second drive shaft 122, the pressing movable block 133 is movably installed on the fixing block 132, and the two form a clamping space; one end of the grinding sheet 131 is inserted into the clamping space and fixed; the other end of the grinding sheet 131 protrudes from the fixing block 132 and the pressing movable block 133.

[0095] Exemplarily, the fixing block 132 is fixedly installed on the second carrier plate 17, and the pressing movable block 133 is disposed on one side of the fixing block 132 and the two are oppositely arranged. The pressing movable block 133 is detachably connected to the fixing block 132, and a clamping space is formed between the pressing movable block 133 and the fixing block 132. One end of the grinding sheet 131 is inserted into the clamping space and fixed, and the other end of the grinding sheet 131 protrudes from the fixing block 132 and the pressing movable block 133. With such a setting, the cleaning component 13 can have grinding sheets 131 of different thicknesses, and the grinding sheets 131 of different thicknesses can be clamped and installed between the fixing block 132 and the pressing movable block 133.

[0096] In one embodiment, the fixed block 132 and the pressing movable block 133 are connected by a fastener (such as a bolt). Among the surfaces of the fixed block 132 and the pressing movable block 133 facing each other, at least one surface is provided with a positioning groove, and the positioning groove cooperates with the abrasive sheet 131, so that the end of the abrasive sheet 131 can be embedded in the positioning groove.

[0097] For example, in the embodiment of the present application, a positioning groove is provided on the surface of the fixed block 132 facing the pressing movable block 133, and a positioning groove is selectively provided on the surface of the pressing movable block 133 facing the fixed block 132. When installing or replacing the abrasive sheet 131, the abrasive sheet 131 can be embedded in the positioning groove of the fixed block 132, and further the pressing movable block 133 is fastened to the fixed block 132 to clamp and fix the abrasive sheet 131 between the fixed block 132 and the pressing movable block 133.

[0098] Furthermore, to avoid interference between the fixed block 132 and the pressing movable block 133 and the outer peripheral wall of the climbing roller 20 during the cleaning process, an arc surface is provided at one end of the fixed block 132 and the pressing movable block 133 facing the climbing roller 20. When the cleaning assembly 13 contacts the outer peripheral wall of the climbing roller 20, a clearance space is formed between the arc surface and the outer peripheral wall of the climbing roller 20.

[0099] Continue to refer to Figure 5 , the cleaning device 10 provided by the embodiment of the present application further includes a first carrier plate 16 and a connecting seat 18, and the first carrier plate 16 is arranged at the end of the first drive shaft 112. For example, the first carrier plate 16 is fixedly connected or detachably connected to the first drive shaft 112, and the embodiment of the present application does not limit this.

[0100] The first carrier plate 16 is used to carry the connecting seat 18, the connecting seat 18 is detachably installed on the first carrier plate 16, and the connecting seat 18 is used to carry the second driving mechanism 12. For example, the second driving mechanism 12 includes a second driving motor 121, and the base of the second driving motor 121 is movably installed on the connecting seat 18, and the installation position of the base relative to the connecting seat 18 in the second direction is adjustable.

[0101] Exemplarily, as Figure 7 shown, in the embodiment of the present application, the cross section of the connecting seat 18 is Z-shaped. The connecting seat 18 includes a bearing wall plate 181, a connecting wall plate 183, and a fixing wall plate 182. The connecting wall plate 183 is arranged between the fixing wall plate 182 and the bearing wall plate 181 and is respectively connected to the fixing wall plate 182 and the bearing wall plate 181. Further, the connecting seat 18 can be an integral structure, the fixing wall plate 182 and the bearing wall plate 181 are horizontally arranged, and the connecting wall plate 183 is vertically arranged.

[0102] In the embodiment of the present application, the fixed wall plate 182 overlaps and is fixed to the top surface of the first bearing plate 16. The connecting wall plate 183 is attached to the side surface of the first bearing wall plate 181, and the bearing wall plate 181 is used for mounting the seat of the second driving mechanism 12.

[0103] The bearing wall plate 181 is provided with a first adjustment mounting hole 1811, which can be a waist-shaped hole. The length direction (adjustment direction) of the first adjustment mounting hole 1811 is consistent with the second direction. The seat is mounted on the connecting seat 18 through fasteners inserted into the first adjustment mounting hole 1811. With such a setting, the position of the second driving mechanism 12 can be adjusted according to the length of the grinding sheet 131 to ensure that the grinding sheet 131 contacts the outer peripheral wall of the climbing roller 20.

[0104] The collection assembly 14 provided in the embodiment of the present application can be selectively mounted on the connecting seat 18 or the first bearing plate 16. To avoid inconvenience caused by the simultaneous installation of the seat of the second driving mechanism 12 and the collection assembly 14 on the connecting seat 18, the collection assembly 14 can be mounted at the bottom of the first bearing plate 16, that is, the connection position between the collection assembly 14 and the first bearing plate 16 is located below the connecting seat 18.

[0105] It should be noted that the collection assembly 14 is mounted on the first bearing plate 16, and the first bearing plate 16 is mounted at the end of the first driving shaft. That is, the collection assembly 14 can move synchronously with the first driving shaft. In other words, when the first driving shaft moves, it can drive the cleaning assembly 13 to axially move relative to the climbing roller 20, and the cleaning assembly 13 and the collection assembly 14 can move synchronously. That is, the collection assembly 14 and the cleaning assembly 13 are relatively stationary, and the collection assembly 14 can collect the foreign objects being swept.

[0106] As Figure 8 shown, the collection assembly 14 includes a collection box 142 and a connecting frame 141. The collection box 142 can be a box body with an open top. The open top is arranged in cooperation with the grinding sheet 131 of the cleaning assembly 13 so that the foreign objects after cleaning can be collected into the collection box 142 through the open top.

[0107] The connecting frame 141 is L-shaped and includes a horizontal section and a vertical section. The horizontal section is connected to the first bearing plate 16, and the vertical section is connected to the collection box 142, and the vertical section is located on one side of the collection box 142 along the second direction. The mounting position of the connecting frame 141 relative to the first bearing plate 16 is adjustable along the second direction.

[0108] Exemplarily, the first carrier plate 16 is provided with a second adjustment mounting hole 1411, the second adjustment mounting hole 1411 may be an oblong hole, and the length direction of the second adjustment mounting hole 1411 is consistent with the second direction. The connecting frame 141 can be mounted on the first carrier plate 16 through a fastener inserted into the second adjustment mounting hole 1411. With such a setting, the position of the collection box 142 can be adjusted to ensure that the foreign objects to be cleaned are collected into the collection box 142.

[0109] As Figure 9 shown, and in combination with Figure 3 , to improve the cleaning effect of the cleaning device, the cleaning device 10 in the embodiment of the present application further includes a cleaning liquid adding component 15. The cleaning liquid adding component 15 includes a suction pump (not shown in the figure), a container (not shown in the figure), and a spray pipeline 151. The container is used to hold the cleaning liquid. For example, the cleaning liquid can be alcohol or the like.

[0110] One end of the spray pipeline 151 is connected to the container, and the other end of the spray pipeline 151 extends to the cleaning component 13 and supplies the cleaning liquid to the cleaning component 13; the suction pump 152 is arranged in the spray pipeline 151. When the suction pump 152 works, it can suck the cleaning liquid in the container. With such a setting, compared with the situation where the cleaning liquid adheres to the skin during manual cleaning and the added cleaning liquid cannot be quantified, in the embodiment of the present application, the cleaning liquid is transported through the suction pump 152, and the automatic addition of the cleaning liquid and the quantification of the added cleaning liquid can be realized.

[0111] It can be understood that in the embodiment of the present application, the spray pipeline 151 is configured as a flexible pipeline and has a deflectable deformation. For example, the spray pipeline 151 is configured as a pipeline composed of multiple bamboo joint pipes and has a deflection. The end of the spray pipeline can be connected to the end of the cleaning component 13 or the second drive shaft 122. The spray pipeline 151 can move synchronously with the cleaning component 13 so as to supply the cleaning liquid to it during the cleaning process of the cleaning component 13. Of course, the cleaning liquid is sprayed between the cleaning component 13 and the outer peripheral wall of the climbing roller 20.

[0112] As Figure 10 shown, the cleaning device 10 provided in the embodiment of the present application can automatically clean the outer peripheral wall of the climbing roller 20, and the cleaning liquid component can automatically supply the cleaning liquid to the cleaning component 13 during the cleaning process.

[0113] Specifically, the cleaning device 10 provided in the embodiment of the present application further includes a control unit 19. The control unit 19 is respectively in signal connection with the first driving mechanism 11, the second driving mechanism 12, and the suction pump 152, that is, the control unit 19 is in signal connection with the controllers of the first driving motor 111, the second driving motor 121, and the suction pump 152.

[0114] Further, the first driving mechanism 11 further includes a first magnetic inductor 113. The first magnetic inductor 113 is disposed on the first driving motor 111 and is in signal connection with the control unit 19. The first magnetic inductor 113 is configured to generate a first signal a and transmit it to the control unit 19 when the first driving shaft 112 fully extends. With such a setting, the control unit 19 obtains the state of the first driving mechanism 11 to control the operation of the second driving mechanism 12.

[0115] After receiving the first signal a, the control unit 19 sends a control signal b to the second driving motor 121, and then the second driving motor 121 operates to extend the second driving shaft 122. The second driving mechanism 12 further includes a second magnetic inductor 123 that is in signal connection with the control unit 19. The second magnetic inductor 123 is configured to generate a second signal c and transmit it to the control unit 19 when the second driving shaft 122 fully extends. With such a setting, the control unit 19 obtains the state of the second driving mechanism 12 to control the operation of the suction pump 152.

[0116] When the second driving shaft 122 fully extends, it can be determined that the cleaning assembly 13 has moved into place and can contact the outer peripheral wall of the climbing roller 20. Therefore, after receiving the second signal c, the control unit 19 sends a control signal d to the suction pump 152 and controls the suction pump 152 to operate so that the suction pump 152 sucks the cleaning liquid and transports it to the cleaning assembly 13. Thus, under the action of the cleaning liquid, it is convenient to clean foreign objects and improve the cleaning effect.

[0117] Based on the above embodiments, the cleaning device 10 provided in the embodiments of the present application further includes a timer 193, a first time relay 191, and a second time relay 192 that are in signal connection with the control unit 19. The first time relay 191 is used to time the working time of the suction pump 152, and when the set time of the first time relay 191 is satisfied, the control unit 19 controls the suction pump 152 to stop working.

[0118] For example, the control unit 19 sends a control signal d to the suction pump 152, and at the same time, this control signal d is sent to the first time relay 191. At this time, the first time relay 191 starts timing to time the working time of the suction pump 152.

[0119] When the working time of the suction pump 152 satisfies the set time of the first time relay 191, the first time relay 191 can send a third signal e to the control unit 19, and then the control unit 19 can send a control signal f to the suction pump 152 to make the suction pump 152 stop sucking.

[0120] The second time relay 192 is used to time the cleaning time of the cleaning assembly 13. When the set time of the second time relay 192 is satisfied, the control unit 19 controls the first driving mechanism 11 and the second driving mechanism 12 to stop working and reset.

[0121] For example, when the control unit 19 receives the third signal e, the control unit 19 can send a control signal g to the first driving motor 111 and control the first driving motor 111 to work, so that the first driving shaft 112 can reciprocate, thereby driving the cleaning assembly 13 to clean the outer peripheral wall of the climbing roller 20.

[0122] Furthermore, the control unit 19 also sends the control signal g to the second time relay 192. At this time, the second time relay 192 starts timing. When the working time of the first driving mechanism 11 satisfies the set time of the second time relay 192, the second time relay 192 can send a fourth signal h to the control unit 19, so that the control unit 19 sends a control signal i to the first driving motor 111 and the second driving motor 121 to control the first driving mechanism 11 and the second driving mechanism 12 to stop working and reset, that is, the first driving mechanism 11 and the second driving mechanism 12 return to the initial position.

[0123] Furthermore, the timer 193 is configured to set the working interval time of the cleaning device 10. When the set interval time of the timer 193 is satisfied, the control unit 19 controls the first driving mechanism 11, the second driving mechanism 12 and the suction pump 152 to work.

[0124] For example, when the control unit 19 receives the fourth signal h, it can be known that the cleaning device 10 has completed a cleaning of the outer peripheral wall of the climbing roller 20. At this time, the cleaning device 10 enters the standby state and waits for the next cleaning task. At the same time, the fourth signal h is sent to the timer 193 to start timing. When the standby time of the cleaning device 10 satisfies the set working interval time, the timer 193 sends a control signal j to the control unit 19, and then the control unit 19 controls the first driving mechanism 11, the second driving mechanism 12 and the suction pump 152 to enter the working state again. In this way, the above process is repeated in turn to automatically clean the climbing roller 20 regularly.

[0125] It can be understood that the cleaning device 10 provided in the embodiment of the present application also has a manual button, and the manual button is signal-connected to the control unit 19. When the foreign matter on the climbing roller 20 needs to be cleaned urgently, it can work without following the time interval set by the timer 193. According to the need, operate the manual button, and the control unit 19 receives the signal and controls the first driving mechanism 11, the second driving mechanism 12 and the suction pump 152 to work to complete a cleaning of the climbing roller 20.
