Description

Technical Field

[0001] The present invention belongs to the technical field of robots, specifically a coal mine conveyor belt intelligent disassembly robot. Background Art

[0002] In coal mine production operations, belt conveyors often have potential hazards due to edge wear and cannot continue to be used. Discarded conveyor belts will accumulate as waste, not only wasting resources but also polluting the environment. Moreover, this work needs to be carried out in a long cycle. Manual cutting has a high labor intensity, low work efficiency, and using a utility knife cannot cut the conveyor belt neatly, and it is also very easy to cause cuts to personnel. The main reasons for the disassembly of coal mine conveyor belts are for maintenance, replacement, or scrapping. During long-term use, the conveyor belt may need to be repaired or replaced due to wear, aging, damage, or other reasons. In addition, when the conveyor belt reaches the end of its service life or can no longer meet the usage requirements, it also needs to be scrapped, and then it needs to be disassembled. The application of conveyor belt disassembly robots is mainly reflected in efficient disassembly, safety guarantee, and intelligent management.

[0003] However, in the process of coal mine production and transportation, there are often large pieces of crushed stones, and sometimes even sundries such as production waste and garbage. These sundries often have sharp edges. Once these sundries get stuck on the idler, rack, or head cleaner scraper, it will cause pressure and continuous friction on the surface of the conveyor belt, and these sundries will get stuck tighter and tighter. Once the surface of the conveyor belt is punctured, the crack will quickly deepen and expand, and finally pierce the conveyor belt, resulting in a tear. Therefore, when the coal mine conveyor belt breaks, effective treatment measures must be taken quickly and professional joint construction must be carried out to ensure that production resumes normal as soon as possible. Moreover, during the disassembly of the conveyor belt, if the robot fails to detect hidden cracks, tears and other parts of the conveyor belt, during subsequent use, it will cause the conveyor belt to break during use, affecting the safety of coal mine transportation.

[0039] Embodiment 1:

[0041] It further includes:

[0042] The connection box 13 is evenly arranged on both sides of the mobile platform 1. A through groove 14 is provided in the middle of one of the connection boxes 13. The inner wall of the connection box 13 with the through groove 14 in the middle is evenly rotatably connected with a rotating disk 16, and the rotating disk 16 is connected to a first driving member 17 installed on the connection box 13. One side of the rotating disk 16 is rotatably connected with a rotating rod 18. The rotating rod 18 includes an upper rotating rod 24 and a lower rotating rod 25. The upper rotating rod 24 is rotatably connected to one side of the rotating disk 16, and one end of the upper rotating rod 24 is connected to a second driving member 19. The lower rotating rod 25 slides in a chute 26 provided on one side of the rotating disk 16, and a slider 27 rotatably connected to one end of the lower rotating rod 25 slides in the chute 26. A spring is provided between the slider 27 and the chute 26. The adjacent connection boxes 13 are clamped and sealed by rubber rings on the side close to each other, and the side far from each other is connected by an electric telescopic rod 15 installed on both sides of the mobile platform 1.

[0043] The cleaning plate 2 is evenly arranged on one side of the rotating disk 16, and one side of the cleaning plate 2 contacts the surface of the conveyor belt. The connection box 13 is evenly provided with a visual detection module 21, and the visual detection module 21 is used to detect the upper and lower surfaces of the conveyor belt. A circulation device 22 is installed on the connection box 13, and the circulation device 22 sprays a chemical agent onto the conveyor belt through a nozzle 23 provided in the connection box 13.

[0044] There are two connection boxes 13, and a cleaning detection component is arranged in one of them. There is an opening at the top of the connection box 13 to facilitate workers to repair the conveyor belt. The rubber ring is a conventional sealing ring for sealing. The electric telescopic rod 15 is a conventional device for realizing the telescopic function. The first driving member 17 and the second driving member 19 are conventional devices for driving parts to rotate, such as motors. The visual detection module 21 is a conventional detection electrical appliance for detecting the conveyor belt by using image shooting. The visual detection technology is applied to the detection of coal mine belts. It mainly shoots the belt in real time through a digital camera and a high-speed image transmission system, and uses computer image processing and pattern recognition technology to detect the belt state.

When at rest, the upper rotating rod 24 is located below the lower rotating rod 25. When working, the upper rotating rod 24 is located on one side of the lower rotating rod 25.

[0045] Specific working process: During the long-term transportation of coal by the conveyor belt, the disassembly robot performs periodic quality inspection, disassembly during maintenance, and disassembly after work on the conveyor belt. Its working method is as follows:

[0046] When inspecting the conveyor belt, the worker controls the mobile platform 1 to move to the designated position of the conveyor belt. The disassembling device 11 lifts a part of the conveyor belt off the ground by means of conventional clamping; then, the electric telescopic rod 15 extends to drive the two connecting boxes 13 to approach each other. The lifted and suspended part of the conveyor belt is inserted into the connecting box 13 through the through groove 14. The worker winds the part located in the connecting box 13 around the rotating rod 18, so that the rotating rod 18 can drive the conveyor belt to rotate by rotation; subsequently, the mutually approaching sides of the two connecting boxes 13 are clamped and sealed by rubber rings, achieving the purpose of combining the two connecting boxes 13 into a box with an opening at the top, so that when the circulating device 22 sprays the medicine into the connecting box 13 through the nozzle 23, it will not flow out from the connection and drip onto the electrical appliances at the bottom of the conveyor belt; the worker drives the rotating disk 16 to rotate by the rotation of the first driving member 17, and the rotating disk 16 drives the rotating rod 18 to swing. The conveyor belt located between adjacent rotating rods 18 is affected by the swing of the rotating rod 18, so that the part of the conveyor belt in contact with the rotating rod 18 is bent into a zigzag shape; on the one hand, it increases the contact area between the conveyor belt and the rotating rod 18, making the rotating rod 18 more effectively drive the conveyor belt to rotate, avoiding contacting the cleaned conveyor belt and causing slipping, improving the inspection efficiency of the conveyor belt, and thus improving the working efficiency of the disassembling robot; on the other hand, it makes the part of the conveyor belt in contact with the rotating rod 18 in a zigzag shape, with both the top and bottom being bent, so that both the upper and lower surfaces of the conveyor belt have bent parts. The visual inspection module 21 inspects the bent parts on the upper and lower surfaces of the conveyor belt. That is, if there are hidden cracks or other scars on the surface of the conveyor belt, the conveyor belt at this part is bent, increasing the surface tension of this part of the conveyor belt, so that the hidden crack wound is opened or enlarged, facilitating the visual inspection module 21 to detect, improving the detection effect, avoiding leaving defects that cause the conveyor belt to break, and preventing the situation that the disassembling robot frequently disassembles and repairs the conveyor belt, thus improving the working effect of the disassembling robot; during the process of the rotating rod 18 driving the conveyor belt to rotate, the cleaning plate 2 rubs against the surface of the conveyor belt, removing the coal impurities on the surface of the conveyor belt, improving the cleanliness of the conveyor belt, and facilitating the visual inspection module 21 to detect; moreover, the circulating device 22 sprays the medicine on the conveyor belt through the nozzle 23, accelerating the removal of the coal on the surface of the conveyor belt, reducing the detection influencing factors, and improving the detection accuracy;

[0047] When repairing the conveyor belt, the worker wraps the two broken ends of the conveyor belt around two groups of rotating rods 18 in the connection box 13 respectively. There is a group of rotating rods 18 on each side of the connection box 13. The nozzle 23 sprays medicine on the broken part of the conveyor belt for cleaning, and then scrapes and cleans the surface of the conveyor belt through the cleaning plate 2. Finally, the rotation of the rotating rod 18 moves the two broken ends of the conveyor belt towards the center of the connection box 13. At this time, the two broken ends of the conveyor belt are in a state of approaching each other, eliminating a large amount of manual work such as pulling and cleaning the two broken ends of the conveyor belt, reducing the working intensity of workers when repairing the conveyor belt, accelerating the repair efficiency of the conveyor belt, and improving the working efficiency of the disassembly robot. Subsequently, the worker repairs the conveyor belt through work such as grinding, gluing, and adding repair materials.

[0048] When disassembling the conveyor belt, while the moving platform 1 drives the disassembly device 11 to move along the conveyor belt, the disassembly device 11 starts to disassemble the conveyor belt along the way one by one, improving the convenience of conveyor belt disassembly.

[0049] Through the application of the above various methods, the disassembly robot can complete disassembly, detection, and repair work, expanding the scope of application of the disassembly robot, thereby improving the practicality.

[0050] Embodiment 2:

[0051] On the basis of Embodiment 1, the inner wall of the connection box 13 is evenly provided with guide plates 28, and one end of the lower rotating rod 25 contacts the guide plate 28. The guide plate 28 is arc-shaped and surrounds the rotating disk 16. One end of the guide plate 28 is far from the center of the rotating disk 16, and the other end is close to the center of the rotating disk 16.

[0052] The cleaning plate 2 is composed of an upper scraping plate 3 and a lower scraping plate 31. The upper scraping plate 3 is located on one side of the upper rotating rod 24, and the lower scraping plate 31 is located on one side of the lower rotating rod 25. One end of the lower scraping plate 31 is fixedly connected to the slider 27. The upper scraping plate 3 contacts the upper surface of the conveyor belt, and the lower scraping plate 31 contacts the lower surface of the conveyor belt. One end of the cleaning plate 2 is provided with a cleaning brush 32, and a fixing plate 33 is provided at the top of the cleaning plate 2. A moving groove 34 is symmetrically opened in the fixing plate 33 with the midline as the axis. The moving groove 34 is composed of four channels in a shape like the Chinese character "ri". The left side of the "ri" shape is the first channel 35, the right side is the second channel 36, the upper and lower sides are the third channels 37, and the middle is the fourth channel 38. A guiding piece 39 is hinged to the connecting part of the fourth channel 38 and the second channel 36 through a torsion spring, and the guiding pieces 39 are symmetrically distributed up and down in the fourth channel 38.

[0053] Two clamping rods 4 are slidably connected in the moving groove 34, and one side of the clamping rod 4 contacts the conveyor belt; a moving plate 41 with a T-shaped cross-section is arranged in the connection box 13, and the two clamping rods 4 are slidably connected to one side of the moving plate 41 through springs, and the moving plate 41 and the fixed plate 33 are connected by springs; the surface of the rotating rod 18 is evenly provided with bumps 42, and the adjacent sides of the bumps 42 are inclined surfaces, and one side of the moving plate 41 contacts the inclined surface in the bumps 42;

[0054] One side of the clamping rod 4 in contact with the conveyor belt is rotatably connected with a cylindrical clamping block 43, and the end of the clamping block 43 is in close contact with a friction plate 44 arranged on the surface of the fixed plate 33. The friction plate 44 is located at one end of the fixed plate 33 and close to the first channel 35; when the clamping block 43 moves up and down, it rotates through the friction with the friction plate 44, and the adjacent clamping blocks 43 rotate in opposite directions;

[0055] The outer surface of the clamping block 43 is hinged with a clamping piece 45 through a torsion spring. The clamping piece 45 is arc-shaped and is evenly distributed annularly;

[0056] The clamping piece 45 is evenly provided with clamping grooves 46, and the cross-section of the clamping grooves 46 is V-shaped.

[0057] Specific working process: When detecting the conveyor belt, after the suspended part of the conveyor belt is lifted and enters the connection box 13, the conveyor belt is located between the upper rotating rod 24 and the lower rotating rod 25 at rest; when the rotating disc 16 drives the rotating rod 18 to swing, while the rotating disc 16 drives the upper rotating rod 24 to swing upward, it drives the lower rotating rod 25 to swing downward, so that the upper rotating rod 24 is located at a position slightly lower than one side of the lower rotating rod 25. The lower surface of the conveyor belt contacts the lower rotating rod 25, and the upper surface contacts the upper rotating rod 24, realizing the effect that the conveyor belt presents a zigzag shape when passing through the rotating rod 18; moreover, when the lower rotating rod 25 swings upward, it contacts the guide plate 28. Since one end of the guide plate 28 is far from the center of the rotating disc 16 and the other end is close to the center of the rotating disc 16, and the arc of the guide plate 28 faces the center of the rotating disc 16, the lower rotating rod 25 is guided by the guide plate 28, so that when the lower rotating rod 25 swings upward, it is squeezed by the guide plate 28 and slides in the chute 26 close to the upper rotating rod 24, achieving the effect that the upper rotating rod 24 and the lower rotating rod 25 squeeze the conveyor belt in the middle, increasing the frictional force between the upper rotating rod 24 and the conveyor belt, and avoiding the situation of slipping caused by the influence of residual chemicals and other moisture when the upper rotating rod 24 drives the conveyor belt to rotate, thereby improving the detection efficiency of the conveyor belt; the lower rotating rod 25 contacts the guide plate 28, while the conveyor belt does not contact the guide plate 28, avoiding the generation of frictional resistance between the conveyor belt and the guide plate 28;

[0058] When repairing the conveyor belt, the worker places the broken ends of the conveyor belt between the upper rotating rod 24 and the lower rotating rod 25 at rest. When the upper rotating rod 24 and the lower rotating rod 25 are working, they clamp and drive the two ends of the conveyor belt, making the broken ends of the conveyor belt approach each other, which is convenient for the worker to carry out the repair operation;

[0059] When the conveyor belt rotates, the upper rotating rod 24 and the upper scraping plate 3 swing upward together, and the lower rotating rod 25 and the lower scraping plate 31 swing downward together. When the lower rotating rod 25 approaches the upper rotating rod 24, it drives the slider 27 to slide in the chute 26. The slider 27 drives the lower scraping plate 31 to approach the upper scraping plate 3 together with the lower rotating rod 25 until the upper scraping plate 3 and the lower scraping plate 31 come into contact. The upper scraping plate 3 cleans the upper surface of the conveyor belt through the cleaning brush 32, and the lower scraping plate 31 cleans the lower surface of the conveyor belt through the cleaning brush 32. Through the driving and cleaning of the conveyor belt by the contact of the upper rotating rod 24 and the lower rotating rod 25, the disassembly robot can adapt to conveyor belts of different thicknesses and improve the scope of application;

[0060] When the moving plate 41 is at rest, the moving plate 41 is located between adjacent bumps 42, and the clamping rod 4 is located in the second channel 36. The two guide pieces 39 are in contact with each other under the influence of the torsion spring to close the communication port between the second channel 36 and the fourth channel 38. When the rotating rod 18 rotates to drive the bump 42 to rotate, one side of the moving plate 41 contacts the two inclined surfaces of the bump 42 and is guided. When the moving plate 41 contacts one inclined surface of the bump 42, the moving plate 41 moves closer to the fixed plate 33 and the conveyor belt. The moving plate 41 drives the clamping rod 4 to move closer to the fixed plate 33 and the conveyor belt. When the clamping rod 4 moves towards the conveyor belt, the combined guide pieces 39 are inserted between adjacent clamping rods 4. The clamping rod 4 is subjected to the inclined guiding action of the guide pieces 39, so that the clamping rod 4 moves from the second channel 36 to the third channel 37, achieving the purpose of separating the two clamping rods 4;

[0061] When the clamping rod 4 touches the surface of the conveyor belt, the clamping rod 4 moves to the communication port between the third channel 37 and the first channel 35. Affected by the spring contraction, the clamping rod 4 moves and merges within the first channel 35 to clamp and pull out the impurities on the surface of the conveyor belt. Then, the moving plate 41 touches the other inclined surface of the convex block 42. The convex block 42 no longer pushes the moving plate 41 towards the conveyor belt. Affected by the spring reset contraction, the moving plate 41 drives the clamping rod 4 to move into the fourth channel 38 and towards the second channel 36 to complete the reset. Until the merged clamping rod 4 drives the impurities to squeeze open and cross the two merged guiding pieces 39. The two guiding pieces 39 swing from the separated state to the merged state after the clamping rod 4 passes by. That is, the clamping rod 4 is in the merged state when stationary, in the separated state when close to the conveyor belt, in the merged state when touching the conveyor belt, and in the merged state when away from the conveyor belt. The effect of clamping the surface of the conveyor belt by the two clamping rods 4 is achieved, and the impurities inserted into the surface of the conveyor belt are pulled out and collected on the cleaning plate 2. Through the cooperation of the cleaning brush 32 and the clamping rod 4, the surface of the conveyor belt is cleaned and the impurities are pulled out, improving the cleaning degree of the conveyor belt, facilitating the detection of the conveyor belt, thereby improving the detection efficiency, and further improving the working efficiency of the disassembly robot;

[0062] Moreover, the clamping rod 4 in the upper scraper 3 clamps and pulls out the impurities on the upper surface of the conveyor belt before the upper surface of the conveyor belt touches the upper rotating rod 24; the clamping rod 4 in the lower scraper 31 clamps and pulls out the impurities on the lower surface of the conveyor belt before the lower surface of the conveyor belt touches the lower rotating rod 25. In this way, it is avoided that the impurities remaining on the surface of the conveyor belt are squeezed and inserted deeper when passing through the upper rotating rod 24 and the lower rotating rod 25, thereby improving the cleaning degree of the surface of the conveyor belt, improving the detection efficiency, and further improving the working efficiency of the disassembly robot;

[0063] When the two clamping rods 4 merge within the first channel 35, the upper clamping rod 4 descends, causing the upper clamping block 43 to contact the friction plate 44 and rotate counterclockwise when descending. The lower clamping rod 4 ascends, causing the lower clamping block 43 to contact the friction plate 44 and rotate clockwise when ascending. When the two clamping rods 4 merge, the two clamping blocks 43 rotate in opposite directions, and the rotation directions are both towards the middle position of the moving plate 41. The clamping blocks 43 use the way of rolling contact to push out the impurities that are not clamped on the surface of the conveyor belt and embed the impurities in the conveyor belt to the clamping rod 4 for collection, increasing the area where the clamping rod 4 pushes the conveyor belt, thereby increasing the amount of impurities pushed out, further improving the cleaning degree of the surface of the conveyor belt, improving the detection efficiency, and further improving the working efficiency of the disassembly robot; After the clamping rod 4 merges, the clamping block 43 moves away from the friction plate 44, and the friction plate 44 does not affect the movement and reset of the clamping block 43;

[0064] The clamping block 43 rotates to drive the arc-shaped clamping piece 45 to rotate. The end of the clamping piece 45 contacts the surface of the conveyor belt, and the impurities embedded in the surface of the conveyor belt are buckled out, improving the cleanliness of the conveyor belt surface, improving the detection efficiency, and further improving the working efficiency of the disassembly robot. Moreover, since a V-shaped clamping groove 46 is provided on the clamping piece 45, if the impurities are embedded too deep in the conveyor belt, it is not easy for the clamping piece 45 to be buckled out. Therefore, when the clamping piece 45 drives the clamping groove 46 to pass by the impurities, the impurities are in the clamping groove 46 and contact the deep part of the V-shape of the clamping groove 46. The clamping groove 46 clamps the impurities through the inner walls on both sides. As the clamping piece 45 moves away from the conveyor belt, the clamping groove 46 pulls out the impurities from the conveyor belt, just like the way a claw hammer pulls out a nail, thereby further improving the cleanliness of the conveyor belt surface.

[0065] Embodiment Three:

[0066] On the basis of Embodiment Two, one end of the cleaning plate 2 is slidably connected with a brush plate 5 through a spring, and the cleaning brush 32 is installed on one side of the brush plate 5. A linkage rod 51 is provided at the end of the brush plate 5. One end of the convex block 42 is provided as an inclined surface. The linkage rod 51 contacts the inclined surface at one end of the convex block 42, and the moving plate 41 contacts the inclined surfaces on both sides of the convex block 42.

[0067] The cleaning brush 32 is composed of a plurality of brush rods 52, and the brush rods 52 are made of elastic material. Brush tubes 53 are provided at the ends of the brush rods 52. The outer surface of the brush tubes 53 contacts the conveyor belt, and both ends of the brush tubes 53 face the two side edges of the conveyor belt respectively. Sawtooth-shaped brush grooves 54 are evenly provided at both ends of the brush tubes 53.

[0068] Specific working process: During the rotation of the convex block 42, the inclined surfaces on both sides of the convex block 42 will contact and pass by the moving plate 41, driving the moving plate 41 to reciprocate along the fixed plate 33. And the inclined surface at one end of the convex block 42 will contact and pass by the end of the linkage rod 51. The end of the linkage rod 51 is guided by the inclined surface at one end of the convex block 42, so that the linkage rod 51 drives the brush plate 5 to laterally move to one side. When the convex block 42 passes over the end of the linkage rod 51, the brush plate 5 is affected by the spring contraction and reset, driving the linkage rod 51 to laterally move and reset to the other side, achieving the purpose of driving the cleaning brush 32 to reciprocate laterally by the brush plate 5, increasing the way of sweeping the conveyor belt left and right by the cleaning brush 32, and improving the cleaning effect of the conveyor belt. Moreover, during the process of the brush plate 5 driving the cleaning brush 32 to move left and right, the cleaning brush 32 is in a compressed and bent state when contacting the conveyor belt. During the process of sweeping to one side, the cleaning brush 32 moves away from the conveyor belt and elastically restores, and the coal mine impurities mixed in the cleaning brush 32 are thrown out through elastic restoration and moving inertia, discharged from the cleaning brush 32, improving the cleanliness during the working process of the cleaning brush 32, thereby improving the cleanliness of the conveyor belt surface, improving the detection efficiency, and further improving the working efficiency of the disassembly robot.

[0069] When the brush plate 5 moves horizontally left and right, the brush pipe 53 is driven to move horizontally left and right by the brush rod 52. The brush pipe 53 contacts and embeds the impurities on the surface of the conveyor belt through the serrated brush grooves 54, and clamps the impurities by the inner walls on both sides. As the brush pipe 53 moves away from the conveyor belt, the clamping groove 46 pulls out the impurities from the conveyor belt, thereby improving the cleaning degree of the conveyor belt surface; moreover, since the brush pipe 53 is circular tubular and the brush grooves 54 are evenly arranged at both ends of the brush pipe 53 and are annularly distributed, even when the brush rod 52 is in a bent state, the brush rod 52 can still drive the brush pipe 53 and the brush grooves 54 to contact the impurities on the conveyor belt surface, further improving the cleaning degree of the conveyor belt.

[0070] Embodiment 4:

[0071] On the basis of Embodiment 3, a fixed frame 55 is provided at one end of the guide plate 28 away from the turntable 16, and the conveyor belt enters the fixed frame 55 from the opening on one side of the fixed frame 55 and runs in the fixed frame 55. The nozzles 23 are evenly installed in the upper and lower inner walls of the fixed frame 55. The nozzles 23 are inclined away from the turntable 16, and the nozzles 23 spray the agent with the color display type onto the conveyor belt; a guide roller 56 is rotatably connected to the cleaning plate 2;

[0072] A maintenance rod 6 is provided in the connection box 13. The maintenance rods 6 are symmetrically distributed up and down. The conveyor belt passes through the space between adjacent maintenance rods 6, and the maintenance rods 6 are away from the turntable 16; a maintenance block 61 is slidably connected in the maintenance rod 6, and the maintenance block 61 is connected to the maintenance rod 6 by bolts;

[0073] An arc-shaped detection plate 62 is provided on one side of the bottom of the maintenance rod 6 close to the turntable 16. The visual detection module 21 is respectively located above the detection plate 62 and on one side of the upper rotating rod 24.

[0074] Specific working process: The fixed frame 55 is U-shaped and has an opening on one side, so that when the connection box 13 is combined, the conveyor belt can enter the inside of the fixed frame 55 through the opening on one side of the fixed frame 55; when the conveyor belt moves in the fixed frame 55, it passes by the nozzles 23, and the nozzles 23 spray the agent with the color display type onto the conveyor belt surface. For example, a conveyor belt cleaning agent with a color opposite to that of the conveyor belt. After the nozzles 23 spray the conveyor belt, these colored agents will penetrate into the internal defects such as hidden cracks on the conveyor belt surface. When detecting after the conveyor belt cleaning is completed, these colored agents will remain inside these defects, achieving the marking effect, enabling the visual detection module 21 to more easily discover these defective parts, facilitating detection, improving the detection efficiency, and thus improving the working efficiency of the disassembly robot; moreover, through the cooperation of the guide roller 56 and the detection plate 62, when the conveyor belt passes through the guide roller 56 and the detection plate 62, the conveyor belt in contact with the upper scraper 3 and the lower scraper 31 can be kept flat;

[0075] During detection, the maintenance rod 6 is not working, and the conveyor belt normally passes through the space between adjacent maintenance rods 6. During repair, both ends of the conveyor belt pass through the maintenance rods 6 on both sides of the connection box 13, and there are two maintenance rods 6 arranged vertically on each side of the connection box 13. When repairing and splicing the broken ends of the conveyor belt, the worker drives the maintenance blocks 61 to approach each other by twisting the bolts, clamping and fixing the broken ends of the conveyor belt, which facilitates the worker's repair work, improves the convenience of using the disassembly robot, and thus improves the practicability.

[0076] The conveyor belt bypasses the upper rotating rod 24, the top of the detection plate 62 and the space between adjacent maintenance rods 6, so that when the conveyor belt passes over the upper rotating rod 24, its lower surface is curved, and when the conveyor belt passes over the detection plate 62, its upper surface is curved, increasing the surface tension of this part of the conveyor belt, causing the hidden crack wound to open or expand, facilitating the visual detection module 21 to detect and improving the detection effect. Moreover, the conveyor belt passing through here has been cleaned, reducing the influence of impurities on the detection result.
