[0060] The exemplary embodiments will be described in detail herein below with reference to the accompanying drawings. In the following description, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all the implementations consistent with the present application. Rather, they are merely examples of methods and apparatuses consistent with some aspects of the present application as detailed in the appended claims.

It is to be understood that the use of the terms so-termed "first", "second", "third", "fourth" and the like in the description and in the claims of the present application is simply intended to differentiate between two or more similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used can be interchanged, where appropriate, to present an embodiment of the present application herein described in other than the order discussed herein. Furthermore, the terms "comprising" and "including" and any of their derivatives, are intended to be construed as encompassing not only the listed members, but also others that are not clearly discernible from the specification and claims, for example, a process, method, system, product or apparatus comprising a series of steps or units need not be limited to only those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to such process, method, product or apparatus.

[0062] As mentioned in the background section, the conveying belt will become black and the gray value will decrease after conveying carbon products such as graphite for a long time, which will affect the photographing and identification of the CCD camera and increase the misarrangement rate of the CCD camera. The existing cleaning mechanism for the conveying belt mainly consists of a brush roller and a negative pressure suction pipe. The brush roller is in contact with the surface of the conveying belt. While the conveying belt is running, the brush roller rotates to clean the surface of the conveying belt. The negative pressure suction pipe then sucks away the dust and other foreign matters brushed off. On the one hand, such cleaning mechanism is generally not flexible to adjust according to the position of the conveying belt and cannot be moved flexibly. The cleaning position is relatively limited. On the other hand, the cleaning effect of the brush roller is limited and cannot remove stubborn graphite and other impurities adhered to the surface of the conveying belt. Therefore, it cannot meet the production needs of the factory.

[0063] In view of the above problems existing in the prior art, the present application provides a cleaning device. The cleaning device provided by the present application comprises a device body, a telescopic unit and a cleaning unit. The device body is used to be placed on one side of the conveying belt. The cleaning unit is connected to the device body through the telescopic unit. The cleaning unit is provided with a cleaning area. When the conveying belt needs to be cleaned, the cleaning unit is driven to move in the first direction through the telescopic unit, so as to cover at least part of the surface of the conveying belt, that is, to move and adjust in the width direction of the conveying belt, so as to ensure that the cleaning unit is aligned with the surface of the conveying belt. When the conveying belt is running, the surface of the conveying belt corresponding to the cleaning area is cleaned through the cleaning unit. That is, the position of the device body is adjustable and the cleaning unit can be adjusted in the width direction of the conveying belt. Therefore, the cleaning position can be adjusted according to the arrangement of the conveying belt, so as to achieve the effect of flexible adjustment.

[0064] The technical solutions of the present application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other. For the same or similar concepts or processes, some embodiments may not be described repeatedly.

[0065] Please refer to Figures 1-5As shown in the figure, this application provides a cleaning device for cleaning a conveyor belt 10. The cleaning device includes a device body 100, a telescopic unit 200 and a cleaning unit 300.

[0066] The cleaning unit 300 is connected to the equipment body 100 via the telescopic unit 200, and the cleaning unit 300 has a cleaning area 301.

[0067] The telescopic unit 200 is configured to drive the cleaning unit 300 to move along a first direction so that the cleaning area 301 covers at least a portion of the surface of the conveyor belt 10.

[0068] The cleaning unit 300 is configured to clean the surface on the conveyor belt 10 corresponding to the cleaning area 301 when the conveyor belt 10 is running.

[0069] In this embodiment, the conveyor belt 10 is used to transport products and other materials. It can be a belt, cloth belt, etc. The conveyor belt 10 can be mounted on the frame by multiple conveyor rollers.

[0070] In this embodiment, the device body 100 serves as a support and provides an installation base. It can have a frame-like, shell-like, or other cabinet structure, and its shape is roughly rectangular. The device body 100 is movable to adjust its placement. Electrical components, control components, etc., can be installed inside the device body 100.

[0071] In this embodiment, the telescopic unit 200 is used to realize the movement and adjustment of the cleaning unit 300. It may be composed of a telescopic mechanism and a guide mechanism, and may be driven manually or electrically. One side of the telescopic unit 200 is connected to the equipment body 100, and the other side of the telescopic unit 200 is connected to the cleaning unit 300. The telescopic unit 200 can drive the cleaning unit 300 to move and adjust laterally.

[0072] The cleaning unit 300 in this embodiment is used to remove impurities such as carbon powder from the surface of the conveyor belt 10. It can be a laser cleaning mechanism, a high-powered brush mechanism, etc.

[0073] Specifically, combined Figure 3 As shown, the above-mentioned equipment body 100 is moved to a suitable position on one side of the conveyor belt 10 without affecting the normal operation of other equipment. The cleaning unit 300 is driven to move along the first direction, that is, along the width direction of the conveyor belt 10, through the telescopic unit 200. Figure 3 As shown in the direction of the X-axis, the cleaning area 301 covers at least a portion of the surface of the conveyor belt 10, so that the cleaning unit 300 can be aligned with the surface of the conveyor belt 10 to achieve the purpose of covering the surface to be cleaned. While the conveyor belt 10 is running, the cleaning unit 300 cleans the surface of the conveyor belt 10 corresponding to the cleaning area 301, removing impurities such as graphite from the surface of the conveyor belt 10.

[0074] Compared with the existing fixed position cleaning mechanism, the application of the cleaning device in the embodiment can meet the flexible placement requirement of the cleaning position by adjusting the position of the device body 100. Then, by moving the cleaning unit 300 along the first direction, i.e., adjusting along the width direction of the conveying belt 10, the cleaning position can be adjusted according to the arrangement of the conveying belt 10, achieving the effect of flexible adjustment.

[0075] Therefore, the cleaning device provided in the embodiment includes the device body 100, the telescopic unit 200, and the cleaning unit 300. The device body 100 is used to be placed on one side of the conveying belt 10. The cleaning unit 300 is connected to the device body 100 through the telescopic unit 200. The cleaning unit 300 is provided with a cleaning area 301. When the conveying belt 10 needs to be cleaned, the cleaning unit 300 is driven to move along the first direction by the telescopic unit 200, so that the cleaning area 301 covers at least part of the surface of the conveying belt 10, i.e., moves and adjusts along the width direction of the conveying belt 10, ensuring that the cleaning unit 300 is aligned with the surface of the conveying belt 10. When the conveying belt is running, the surface of the conveying belt 10 corresponding to the cleaning area is cleaned by the cleaning unit 300. That is, the position of the device body 100 is adjustable, and the cleaning unit 300 can be adjusted along the width direction of the conveying belt 10, so that the cleaning position can be adjusted according to the arrangement of the conveying belt 10, achieving the effect of flexible adjustment.

[0076] In a possible design, the telescopic unit 200 includes at least two mounting members 210 connected in sequence by sliding. One of the two adjacent mounting members 210 slides relative to the other along the first direction.

[0077] One of the two mounting members 210 facing away from each other is connected to the device body 100, and the other is connected to the cleaning unit 300.

[0078] The mounting member 210 facing away from the device body 100 is driven to slide along the first direction, so as to adjust the transverse position of the cleaning unit 300 corresponding to the surface of the conveying belt 10.

[0079] Specifically, the mounting member 210 is used for mounting, supporting, etc., which can be a plate, a frame, a shell, etc. For example, as shown in Figure 4 The mounting member 210 is a mounting plate, and three mounting plates are provided. The first mounting plate is fixedly connected to the device body 100. The second mounting plate can be connected to the first mounting plate through a sliding assembly or a sliding structure. The third mounting plate can also be connected to the second mounting plate through a sliding assembly or a sliding structure. The cleaning unit 300 can be mounted on the third mounting plate.

[0080] The second mounting plate and the third mounting plate are both slidable relative to the first mounting plate in a first direction, such as a direction along Figure 4 the X-axis direction. In this way, the cleaning unit 300 can be driven to move in the lateral direction by moving either the second mounting plate or the third mounting plate, so as to adjust the lateral position of the cleaning unit 300 to meet the requirement of aligning with the surface of the conveying belt 10.

[0081] Of course, the mounting member 210 can also be provided in a smaller or larger number, two mounting members 210 forming a one-stage telescopic structure, three mounting members 210 forming a two-stage telescopic structure, and so on. The specific number and structure of the mounting member 210 can be determined according to actual requirements, and are not limited in the present embodiment.

[0082] Further, in the present embodiment, a limiting member 201 is arranged between two adjacent mounting members 210, and is used to limit or release the relative sliding between the two adjacent mounting members 210.

[0083] Specifically, as shown in Figure 4 , the limiting member 201 can be a limiting bolt, which can be screwed on one of the two adjacent mounting members 210. When the limiting bolt is tightened, the limiting bolt is in contact with the other mounting member 210, so as to limit the relative movement of the two mounting members 210 and lock the cleaning unit 300 in the current position. When the limiting bolt is loosened, the limiting bolt is out of contact with the other mounting member 210, so as to release the limitation, and the mounting member 210 can be moved for adjustment.

[0084] Of course, the limiting member 201 can also be replaced by other types of limiting components, such as a pin, a bolt, a pressing block, etc. Any component that can lock the two adjacent mounting members 210 can be used, and the present embodiment is not limited in this regard.

[0085] Further, in the present embodiment, the two adjacent mounting members 210 are connected by a sliding assembly 202. In this way, the stability of the telescopic unit 200 can be ensured under the action of the sliding assembly 202.

[0086] Specifically, as shown in Figure 4 , the sliding assembly 202 can be composed of a sliding block and a guide rail. The guide rail can be fixedly connected to one of the two adjacent mounting members 210, and the extension direction of the guide rail is consistent with the sliding direction of the mounting member 210. The sliding block can be fixedly connected to the other mounting member 210.

[0087] In this way, the two adjacent mounting members 210 can be stably slid by the cooperation of the sliding block and the guide rail. Of course, the sliding assembly 202 can also be replaced by other types of sliding components, and the present embodiment is not limited in this regard.

[0088] Further, in the embodiment, the telescopic unit 200 further comprises a drag chain 220, and the mounting piece 210 connected with the cleaning unit 300 is provided with a bracket 211.

[0089] One end of the drag chain 220 is connected to the mounting piece 210 connected with the device body 100, and the other end of the drag chain 220 is connected to the bracket 211 after passing by the side away from the cleaning unit 300.

[0090] Specifically, as shown in Figure 4 , the first mounting piece 210 is fixedly connected to the device body 100, the bracket 211 is arranged on the mounting piece 210 farthest from the first mounting piece 210 (i.e. the last mounting piece 210), one end of the drag chain 220 is fixedly connected to the first mounting piece 210, and the other end of the drag chain 220 is fixedly connected to the bracket 211 after passing by the side away from the cleaning unit 300, and the drag chain 220 can satisfy the arrangement of the wire harness and the pipeline, and the wire harness and the pipeline can be used for connecting the cleaning unit 300 and the control unit, so as to avoid the wire mess.

[0091] Among them, the specific model, number, installation position, etc. of the drag chain 220 can be determined according to actual needs, which are not limited in the embodiment.

[0092] In some embodiments, the lifting unit 400 and the moving unit 500 are further included, and the device body 100 is arranged on the moving unit 500 through the lifting unit 400.

[0093] The lifting unit 400 is configured to drive the device body 100 to lift to adjust the distance between the cleaning unit 300 and the surface of the conveying belt 10.

[0094] Specifically, as shown in Figure 1 , 2 , the lifting unit 400 is used for lifting the device body 100, which can be a scissor lifting mechanism, or a lifting mechanism composed of a gas cylinder, an oil cylinder, an electric push rod and a guide rod. The moving unit 500 can be a moving trolley, i.e. a plurality of wheels are arranged at the bottom of the base, and the wheels are provided with a brake mechanism.

[0095] When the device body 100 is arranged on the moving unit 500 through the lifting unit 400, the moving unit 500 can facilitate the movement of the device body 100, and the lifting unit 400 can facilitate the adjustment of the height of the device body 100, thereby adjusting the vertical distance between the cleaning unit 300 and the conveying belt 10, so that the adjustment is more flexible.

[0096] Further, in the embodiment, the lifting unit 400 comprises a lifting mechanism 410, a detection piece 420 and an alarm 430, and the device body 100 is connected to the moving unit 500 through the lifting mechanism 410.

[0097] The detection member 420 is configured to detect the distance between the cleaning unit 300 and the surface of the conveyor belt 10, and the alarm 430 is configured to send an alarm signal when the detection member 420 detects that the distance is a preset distance.

[0098] Specifically, as shown in Figure 1 The lifting mechanism 410 can be a scissor lifting mechanism, or a lifting mechanism composed of a pneumatic cylinder, an oil cylinder, an electric push rod, and a guide rod. The device body 100 is connected to the moving unit 500 by the lifting mechanism 410. The detection member 420 can be a distance measuring sensor, a range finder, etc., which can be arranged on the cleaning unit 300 to detect the distance between the cleaning unit 300 and the surface of the conveyor belt 10. The alarm 430 can be an audible and visual alarm, a buzzer alarm, etc.

[0099] When the device body 100 is driven to move up and down by the lifting mechanism 410, and the detection member 420 detects that the distance is a preset distance, the alarm 430 sends an alarm signal, indicating that the cleaning height is appropriate. The specific types of the detection member 420 and the alarm 430, etc. can be determined according to actual needs, and are not limited in the present embodiment.

[0100] In some embodiments, the cleaning unit 300 includes a laser 310, a reflector 320, and a focusing mirror 330. The laser 310 is configured to output a laser beam.

[0101] The reflector 320 is configured to reflect the laser beam to the focusing mirror 330. The focusing mirror 330 is configured to focus the laser beam to form a light spot, which is configured to irradiate the surface of the conveyor belt 10.

[0102] Specifically, as shown in Figure 5 The laser 310 is configured to emit a laser beam, which can be one of a fiber laser, a disc laser, a semiconductor laser, or a carbon dioxide laser, etc., capable of achieving efficient removal of large-format paint, rust, and oil stains. Compared with brush dust removal, the laser can disperse stubborn impurities adhering to the surface of the conveyor belt 10, and the cleaning is more thorough.

[0103] The reflector 320 is arranged in the emission light path of the laser 310, and is configured to reflect the laser beam emitted by the laser 310 to the focusing mirror 330. The focusing mirror 330 is arranged in the reflected light path of the reflector 320, and is configured to focus the reflected laser beam to form a light spot, i.e. a parallel light beam is focused to form a focused light spot, which can greatly improve the efficiency of laser cleaning.

[0104] The laser 310, the mirror 320 and the focusing mirror 330 can be packaged in a shell to form a laser head, and the laser head is mounted on the telescopic unit 200. The specific types, numbers, positions and the like of the laser 310, the mirror 320 and the focusing mirror 330 can be determined according to actual needs, and are not specifically limited in the embodiment.

[0105] Further, in the embodiment, the cleaning unit 300 further includes a driving member 340 connected with the mirror 320.

[0106] The driving member 340 is configured to drive the mirror 320 to swing back and forth along the width direction of the conveying belt 10 by a preset angle, so that the laser beam forms the cleaning area 301 from the linear beam.

[0107] Specifically, as shown in Figure 5 , the driving member 340 is used to drive the mirror 320 to deflect, which can be a motor or the like, and the mirror 320 is mounted on the output end of the motor. When the motor drives the mirror 320 to swing back and forth along the width direction of the conveying belt 10 by a preset angle, the emitted light spot forms the cleaning area 301, that is, the laser cleaning area formed by the deflection of the plurality of light spots, which can cover the width of the conveying belt 10, thereby further improving the cleaning efficiency.

[0108] It should be noted that the preset angle can be determined according to the width of the conveying belt 10 and the distance between the focusing mirror 330 and the conveying belt 10, and is not specifically limited in the embodiment.

[0109] In addition, the mirror 320 and the driving member 340 can also be replaced by a cylindrical mirror, and the emitted laser beam can be shaped by the cylindrical mirror to finally form a laser cleaning area. For this purpose, it can be determined according to actual needs, and is not limited too much in the embodiment.

[0110] In some embodiments, a controller 600 is further arranged on the device body 100, and the laser 310 and the driving member 340 are electrically connected with the controller 600.

[0111] The controller 600 is used to control the light emission parameters of the laser 310, and the controller 600 is further used to control the driving member 340 to swing at a preset angular velocity.

[0112] In this way, the controller 600 can control the light emission parameters of the laser 310, which can be the laser power, the modulation frequency and the on-off of the laser 310, and the controller 600 can control the deflection angular velocity of the driving member 340 to adapt to the cleaning requirements of the conveying belt 10 with different widths and running speeds.

[0113] It should be noted that the preset angular velocity can be determined based on the width of the conveyor belt 10 and the distance between the focusing lens 330 and the conveyor belt 10, but no specific limitation is made in this embodiment.

[0114] In some embodiments, a dust removal unit 700 is also provided on the device body 100, the dust removal unit 700 being used to remove foreign objects that are knocked off the surface of the conveyor belt 10 by the light spot.

[0115] In this way, while lasers knock off foreign objects from the surface of the conveyor belt 10, the dust removal unit 700 simultaneously sucks or blows away the foreign objects, thus ensuring that the surface of the conveyor belt 10 remains clean. The dust removal unit 700 can remove the foreign objects through negative pressure suction or by blowing them away with a powerful fan.

[0116] In one specific embodiment, the dust removal unit 700 includes an adsorption element 710 and a negative pressure element 720. The adsorption element 710 is used to be disposed on one side of the conveyor belt 10 where it is irradiated by the light spot.

[0117] The adsorption element 710 is connected to the negative pressure element 720, which provides suction to remove foreign objects through the adsorption element 710.

[0118] Among them, such as Figure 2 As shown, the adsorption component 710 can be a suction pipe, a suction hood, a suction housing, etc., and can be installed on the equipment body 100, with the suction port facing the position on the conveyor belt 10 illuminated by the light spot. The negative pressure component 720 can be a negative pressure pump, etc., and can be installed inside the equipment body 100. The adsorption component 710 is connected to the negative pressure component 720 through a pipeline.

[0119] In this way, the negative pressure component 72 can suck away foreign objects on the conveyor belt 10 at the location irradiated by the light spot through the adsorption component 710. The specific type and structure of the adsorption component 710 and the negative pressure component 720 can be determined according to actual needs, and are not specifically limited in this embodiment.

[0120] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the application disclosed herein.
