Description

Technical Field

[0001] This application relates to the field of spraying equipment, and more particularly to an intelligent robot spraying device. Background Technology

[0002] Furniture typically requires painting during production to enhance its appearance and protect it.

[0003] Currently, a chassis-type spray painting line is disclosed, including a slide rail with a support plate sliding along it. A raised block is installed on the top surface of the support plate. A robotic arm with a spray head is mounted on one side of the slide rail. The spray head is equipped with a feeding mechanism. The sheet material is placed on the support plate, which moves along the slide rail. The feeding mechanism then supplies paint to the spray head, and the robotic arm moves the spray head, causing it to spray paint onto the sheet material placed on the support plate. Workers then remove the sheet material from the support plate. The painted sheet material is then assembled to form furniture.

[0004] Regarding the aforementioned related technologies, the inventors believe that when the robotic arm moves the spray head to spray paint the perimeter of the board, one side wall of the board is away from the robotic arm. Therefore, the robotic arm needs to pass over the board from above, and then rotate the spray head towards the side wall away from the robotic arm to spray. As the robotic arm rotates the spray head towards the side wall away from the robotic arm, the direction of the spray will also be towards the robotic arm, causing some paint to drift into the air and adhere to the robotic arm. Summary of the Invention

[0005] To reduce the occurrence of paint sticking to the robotic arm, this application provides an intelligent robot spraying device.

[0006] This application provides an intelligent robot spraying device, which adopts the following technical solution: A smart robot spraying device includes a chain conveyor, a base on the bottom side of the chain conveyor, a rotating disk on the top side of the base, a first motor installed between the base and the rotating disk to drive the rotating disk to rotate, a cylinder installed on the top surface of the rotating disk to extend and retract along the height direction, side plates fixedly installed on both sides of the chain conveyor, a support plate placed on the top side of the chain conveyor, the side wall of the support plate abutting against the side plate, a shim block installed on the top surface of the support plate for placing the material, a robot arm installed on one side of the base, a spray head installed on the robot arm, and a feeding mechanism installed on the spray head for supplying paint to the spray head.

[0007] By employing the above technical solution, the sheet material is placed on a support plate, which is then placed on a chain conveyor. The chain conveyor then transports the support plate to the location of the robotic arm. A feeding mechanism supplies paint to the spray nozzle, and the robotic arm moves the spray nozzle, causing it to spray paint onto the sheet material placed on the support plate. When spraying the side of the sheet material away from the robotic arm, a cylinder pushes the support plate upwards, and then a first motor drives the cylinder to rotate via a rotating disk, thus turning the side of the sheet material that was previously away from the robotic arm towards it. When the side of the sheet material that was previously away from the robotic arm is now facing it, the cylinder descends, causing the support plate to be repositioned on top of the chain conveyor. The robotic arm then moves the spray nozzle to perform spraying, thereby reducing the occurrence of paint sticking to the robotic arm.

[0008] Optionally, a guide plate is fixedly installed on the top side of the side plate, and the guide plates on both sides of the chain conveyor are bent in a direction away from each other.

[0009] By adopting the above technical solution, when the cylinder drives the support plate to descend and be placed on the top side of the chain conveyor, the guide plate guides the support plate, thereby facilitating the support plate to fall between the two side plates.

[0010] Optionally, a limiting block is installed on the bottom side of the support plate, the cylinder body of the cylinder is fixedly connected to the top surface of the rotating disk, a support block is installed on the piston rod of the cylinder, and a limiting groove is opened on one side of the support block for the limiting block to enter.

[0011] By adopting the above technical solution, the limiting block enters the limiting groove, thereby restricting the chain conveyor from continuing to move the support plate. After the first motor drives the cylinder to rotate via the rotating disk, the limiting block engages with the inner wall of the limiting groove, facilitating the rotation of the support plate along with the cylinder. After the first motor drives the first cylinder to rotate, the opening of the limiting groove faces the end of the chain conveyor in the conveying direction, facilitating the chain conveyor to continue transporting the support plate. When the limiting block moves out of the limiting groove, the first motor drives the cylinder to reset via the rotating disk.

[0012] Optionally, the bottom surface of the support plate is provided with multiple screw holes, which are spaced apart along the width direction of the chain conveyor. A screw is fixedly installed on the top side of the limiting block, and the screw is threaded into the screw hole. The piston rod of the cylinder is fixedly installed with a mounting base, which is provided with multiple insertion holes, which are spaced apart along the width direction of the chain conveyor. A plug rod is fixedly installed on the bottom side of the support block, and the plug rod is used for damping insertion into the insertion hole.

[0013] By adopting the above technical solution, multiple robotic arms are installed on one side of the chain conveyor. When each robotic arm drives a spray head to spray a sheet, there are multiple support plates on the chain conveyor. Screws are inserted into different screw holes, and insert rods are inserted into different insert holes, so that the support plates can stop moving when they move to the corresponding robotic arm.

[0014] Optionally, the top surface of the support plate is provided with multiple slots, which are evenly distributed on the top surface of the support plate. The bottom side of the shim block is fixedly installed with an insert block, which is damped and inserted into the slot.

[0015] By adopting the above technical solution, the support of the shim blocks on the support plate is adjusted according to the size of the plate placed on the support plate, thereby improving the stability of the shim blocks supporting the plate.

[0016] Optionally, the support plate is provided with a shielding film, which covers the top surface, the periphery and the bottom edge of the support plate. Both sides of the support plate are provided with mounting frames, which are damped and fitted onto the support plate.

[0017] By adopting the above technical solution, when the spray nozzle sprays paint onto the board, some of the paint adheres to the masking film, thus reducing the occurrence of paint sticking to the support plate. When the masking film needs to be replaced, the mounting block is removed from the support plate, and then the masking film is replaced. After replacing the masking film, the mounting frame is re-inserted into the support plate, thereby fixing the masking film to the support plate.

[0018] Optionally, a first absorption pipe is installed on both sides of the chain conveyor, and a second and third absorption pipe are sequentially installed along the conveying direction. The first, second, and third absorption pipes are each provided with multiple absorption holes. The first, second, and third absorption pipes are all connected to an exhaust pipe, and an exhaust pump is installed on the exhaust pipe. An exhaust pipe is installed at the end of the exhaust pump away from the exhaust pipe. Both ends of the first, second, and third absorption pipes are sealed. The first, second, and third absorption pipes are used to absorb the coating material around the support plate.

[0019] By adopting the above technical solution, when the chain conveyor transports the support plate to the position of the robotic arm, the first, second, and third absorption pipes surround the support plate. Then, when the spray nozzle sprays paint onto the plate, the paint disperses into the air. The air carries the paint through the absorption holes into the first, second, and third absorption pipes. The paint is then discharged from the exhaust pipe and vent pipe, thus reducing the likelihood of paint dispersing into the air and sticking to the machinery and the chain conveyor.

[0020] Optionally, the second absorption tube is provided with a first drive rod and a first rotating rod. The first rotating rod is located inside the chain conveyor, and its end is rotatably inserted into the inner wall of the chain conveyor. The shaft of the first drive rod is rotatably mounted on the shaft of the first rotating rod. The first drive rod rotates around the first rotating rod as an axis. One end of the first drive rod is fixedly connected to the tube body of the second absorption tube, and the other end of the first drive rod is fixedly mounted with a first counterweight. The weight of the second absorption tube is greater than that of the first counterweight. A pressure block is fixedly mounted on the bottom side of the support plate. The pressure block is used to press against the first counterweight.

[0021] By adopting the above technical solution, when the chain conveyor transports the support plate to the position of the robot arm, the support plate presses against the first counterweight, thereby pushing the first drive rod to rotate. The first counterweight then moves below the support plate. When the support plate moves to the position of the robot arm, the pressure block presses against the first counterweight, causing the first drive rod to continue rotating. The first drive rod drives the second absorption tube to move upward, facilitating the entry of air and paint into the second absorption tube. After the paint is applied to the material on the support plate, the chain conveyor transports the support plate away from the position of the robot arm, and the second absorption tube rotates downward under gravity. The automatic raising and lowering of the second absorption tube along with the movement of the support plate reduces the likelihood of the second absorption tube obstructing the movement of the support plate.

[0022] Optionally, the third absorption tube is provided with a second drive rod and a second rotating rod. The second rotating rod is located inside the chain conveyor, and the end of the second rotating rod is rotatably inserted into the inner wall of the chain conveyor. The body of the second drive rod is rotatably mounted on the body of the first rotating rod. The second drive rod rotates around the second rotating rod as an axis. One end of the second drive rod is fixedly connected to the tube body of the third absorption tube, and the other end of the second drive rod is fixedly mounted with a second counterweight. The weight of the third absorption tube is less than that of the second counterweight.

[0023] By adopting the above technical solution, when the chain conveyor transports the support plate to the position of the robot arm, the support plate abuts against the third absorption tube. After the plate on the support plate is painted, the chain conveyor transports the support plate away from the position of the robot arm. The support plate presses against the third absorption tube, causing the third absorption tube to rotate downwards, thereby facilitating the movement of the support plate.

[0024] Optionally, the feeding mechanism includes a storage tank, a feeding pump, a feeding pipe, a second motor, a stirring rod, and stirring blades. The storage tank is located on one side of the robot arm. The pump body of the feeding pump is fixedly installed in the storage tank. The inlet end of the feeding pump is connected to the storage tank. The outlet end of the feeding pump is connected to one end of the feeding pipe. The other end of the feeding pipe is connected to the nozzle. The body of the second motor is fixedly installed on the top side of the storage tank. The stirring rod and stirring blades are located inside the storage tank. One end of the stirring rod is fixedly connected to the rotating shaft of the second motor. The stirring blades are fixedly installed on the body of the stirring rod.

[0025] By adopting the above technical solution, the second motor drives the stirring rod to rotate, and the stirring rod drives the stirring blades to stir the paint inside the storage tank, thereby reducing the occurrence of paint sedimentation inside the storage tank.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. When the robotic arm drives the spray head to spray the board, if it is necessary to spray the side of the board away from the robotic arm, the cylinder drives the support plate to rise, and then the first motor drives the cylinder to rotate through the rotating plate, thereby rotating the support plate. The support plate moves the side of the board that was originally away from the robotic arm to the side that is closer to the robotic arm, thereby reducing the occurrence of the spray head spraying towards the robotic arm, and thus reducing the occurrence of paint sticking to the robotic arm. 2. Start the exhaust pump to draw air, so that the paint scattered in the air enters the first absorption pipe, the second absorption pipe and the third absorption pipe, thereby reducing the occurrence of paint sticking to the robot arm.

[0029] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0030] This application discloses an intelligent robot spraying device.

[0031] Reference Figure 1 A smart robot spraying device includes a chain conveyor 1, with chains on both sides for transport, and an empty middle section. A support plate 2 is placed on the top side of the chain conveyor 1. The chain conveyor 1 drives the support plate 2 to move. Reference Figure 2 , Figure 3 The support plate 2 is equipped with a shielding film 3, which covers the top surface, perimeter, and bottom edge of the support plate 2. Mounting frames 4 are provided on both sides of the support plate 2, and the mounting frames 4 are damped and fitted onto the support plate 2. The shielding film 3 protects the support plate 2, thereby reducing the occurrence of paint adhering to the top surface of the support plate 2. When there is excessive paint on the shielding film 3, or when the shielding film 3 is damaged, the mounting frames 4 are removed from both sides of the support plate 2. Then, the damaged shielding film 3 is removed from the support plate 2, and a new shielding film 3 is re-wrapped around the support plate 2. The mounting blocks fit onto both sides of the support plate 2, facilitating the replacement of the shielding film 3.

[0032] Reference Figure 1 , Figure 2The outer wall of the mounting frame 4 has anti-slip textures, and the support plate 2 is pressed onto the chain of the chain conveyor 1 through the mounting frame 4. Then, through the friction between the mounting frame 4 and the chain conveyor 1, the chain conveyor 1 can easily move the support plate 2. Moreover, after the anti-slip textures on the outer wall of the mounting frame 4 wear down, a new mounting frame 4 can be replaced, and the support plate 2 can be reused, thus saving resources.

[0033] Reference Figure 1 Side plates 5 are fixedly installed on both sides of the chain conveyor 1. When the support plate 2 is placed on the chain conveyor 1, the side wall of the support plate 2 abuts against the side plate 5, thereby reducing the occurrence of the support plate 2 tilting to both sides when the chain conveyor 1 transports the support plate 2.

[0034] A guide plate 6 is fixedly installed on the top side of the side plate 5. The guide plates 6 on both sides of the chain conveyor are bent in a direction away from each other. When the support plate 2 is placed into the chain conveyor 1, the two sides of the support plate 2 are guided by the guide plates 6, which makes it easier for the support plate 2 to be placed between the two side plates 5.

[0035] Reference Figure 3 A shim block 7 is provided on the top surface of the support plate 2, and an insert block 8 is fixedly installed on the bottom side of the shim block 7. Multiple slots 9 are provided on the top surface of the support plate 2 for the damped insertion of the insert block 8. After the insert block 8 pierces the masking film 3, it is inserted into the slot 9, thereby installing the shim block 7 onto the support plate 2. The material to be sprayed is then placed on the shim block 7. The shim block 7 elevates the material, facilitating spraying around its perimeter. The shim block 7 moves by inserting the insert block 8 into different slots 9, thus supporting the edges of the material on the support plate 2 and improving the stability of the material placed on the support plate 2.

[0036] Reference Figure 1 , Figure 4 At least one robotic arm 10 is provided on one side of the chain conveyor 1. In this embodiment, there is only one robotic arm 10. In another embodiment, there are three robotic arms 10, and the three robotic arms 10 are spaced apart along the length of the chain conveyor 1.

[0037] Reference Figure 6 , Figure 7 The robotic arm 10 is equipped with a spray head 11, and the spray head 11 is equipped with a feeding mechanism 12. After the chain conveyor 1 moves the support plate 2 to the position of the robotic arm 10, the robotic arm 10 drives the spray head 11 to move, and then the feeding mechanism 12 supplies paint to the spray head 11, thereby spraying the paint onto the plate.

[0038] Reference Figure 6 , Figure 7The feeding mechanism 12 includes a storage tank 121, a feeding pump 122, a feeding pipe 123, a second motor 124, a stirring rod 125, and a stirring blade 126. The storage tank 121 is located on one side of the robot arm 10, and the pump body of the feeding pump 122 is fixedly installed on one side of the storage tank 121. The inlet end of the feeding pump 122 is connected to the storage tank 121, and the outlet end of the feeding pump 122 is connected to one end of the feeding pipe 123. The other end of the feeding pipe 123 is connected to the nozzle 11. When the feeding pump 122 is started, the pump draws the paint from inside the storage tank 121 into the feeding pipe 123, the feeding pipe 123 delivers the paint to the nozzle 11, and then the nozzle 11 sprays the paint out.

[0039] Reference Figure 6 , Figure 7 The body of the second motor 124 is fixedly installed on the top side of the storage tank 121, and the stirring rod 125 and stirring blade 126 are located inside the storage tank 121. One end of the stirring rod 125 is fixedly connected to the rotating shaft of the second motor 124, and the stirring blade 126 is fixedly installed on the body of the stirring rod 125. When the second motor 124 is started, it drives the stirring rod 125 to rotate, and the stirring rod 125 drives the stirring blade 126 to stir the paint inside the storage tank 121, thereby reducing the occurrence of paint sedimentation.

[0040] Reference Figure 7 , Figure 8 The chain conveyor 1 has at least one base 13 on its bottom side, the number of bases 13 being the same as the number of robot arms 10, and each base 13 corresponds to one robot arm 10. A rotating disk 14 is provided on the top side of the base 13, and a first motor 15 is installed between the base 13 and the rotating disk 14. The first motor 15 is used to drive the rotating disk 14 to rotate.

[0041] A cylinder 16 is mounted on the top surface of the rotating disk 14, and the cylinder body of the cylinder 16 is fixedly connected to the top surface of the rotating disk 14. A mounting base 17 is fixedly mounted on the piston rod of the cylinder 16. A support block 18 is provided on the mounting base 17, and a plug rod 19 is fixedly mounted on the bottom side of the support block 18. The mounting base 17 has multiple insertion holes 20 for damped insertion of the plug rod 19.

[0042] Insert rod 19 is inserted into insertion hole 20, thereby mounting support block 18 on top side of mounting base 17. When robot arm 10 drives spray head 11 to spray the side of the board away from robot arm 10, cylinder 16 is activated. Cylinder 16 drives support plate 2 upward through mounting base 17 and support block 18. When the bottom surface of support plate 2 is higher than the top side of guide plate 6, cylinder 16 stops driving support plate 2 upward, and then first motor 15 drives cylinder 16 to rotate through rotating disk 14. Through the friction between support plate 2 and support block 18, support plate 2 rotates with cylinder 16, thereby moving the side of the board that was originally away from robot arm 10 closer to robot arm 10. Then the piston rod of cylinder 16 retracts, and support plate 2 descends. After being aligned under the guidance of two guide plates 6, support plate 2 is placed on chain conveyor 1. Afterwards, when the robotic arm 10 drives the spray nozzle 11 to spray the surrounding area of ​​the material that was originally far away from the robotic arm 10, the spray nozzle 11 will not face the robotic arm 10 directly, thereby reducing the occurrence of paint drifting in the air and sticking to the robotic arm 10.

[0043] Reference Figure 8 , Figure 9 A limiting block 21 is provided on the bottom side of the support plate 2, and a screw 22 is fixedly installed on the top side of the limiting block 21. Multiple screw holes 23 are provided on the bottom surface of the support plate 2 for threaded insertion of the screw 22, and these screw holes 23 are spaced apart along the width direction of the chain conveyor 1. A limiting groove 24 is provided on one side of the support block 18 for the limiting block 21 to enter.

[0044] The screw 22 is screwed into the screw hole 23, thereby installing the limiting block 21 on the bottom surface of the support plate 2. When the chain conveyor 1 transports the support plate 2 to the position of the robot arm 10 for spraying, the limiting block 21 enters the limiting groove 24, thereby restricting the conveyor from driving the support plate 2 to continue moving. When the first motor 15 drives the support plate 2 to rotate, the limiting block 21 engages with the inner wall of the limiting groove 24, thereby facilitating the rotation of the support plate 2.

[0045] When there are at least two robotic arms 10 on one side of the chain conveyor 1, the operator needs to place at least two support plates 2 on the chain conveyor 1. The position of the limiting block 21 is changed by inserting the screw 22 into different screw holes 23; and the position of the support block 18 is changed by inserting the insertion rod 19 into different insertion holes 20. This allows the limiting blocks 21 on different support plates 2 to be staggered, and the support blocks 18 at different positions of the robotic arms 10 to be staggered, thus facilitating the entry of one support plate 2 into the position of one robotic arm 10.

[0046] Reference Figure 7 , Figure 10The chain conveyor 1 has a first absorption pipe 25 fixedly installed on both sides, and a second absorption pipe 26 and a third absorption pipe 27 are installed sequentially along the conveying direction. When the support plate 2 moves to the position of the robot arm 10, the first absorption pipe 25, the second absorption pipe 26 and the third absorption pipe 27 surround the support plate 2.

[0047] Reference Figure 7 , Figure 10 Each of the first absorption pipe 25, the second absorption pipe 26, and the third absorption pipe 27 has multiple absorption holes 28. Both ends of the first absorption pipe 25, both ends of the second absorption pipe 26, and both ends of the third absorption pipe 27 are sealed. Each of the first absorption pipe 25, the second absorption pipe 26, and the third absorption pipe 27 is connected to an exhaust pipe 30, and an exhaust pump 29 is installed on the exhaust pipe 30. An exhaust pipe 31 is installed at the end of the exhaust pump 29 furthest from the exhaust pipe 30.

[0048] When the robotic arm 10 drives the spray head 11 to spray the board, the exhaust pump 29 is activated. The exhaust pump 29 draws in air, causing the paint dispersed in the air to enter the first absorption pipe 25, the second absorption pipe 26, and the third absorption pipe 27 through the absorption hole 28. The paint is then discharged with the air through the exhaust pipe 30 and the exhaust pipe 31. The end of the exhaust pipe 31 away from the exhaust pump 29 can be connected to a filter device. The air is then discharged after being filtered by the filter device.

[0049] Reference Figure 7 , Figure 10 The second absorption tube 26 is equipped with a first drive rod 32 and a first rotating rod 34. The first rotating rod 34 is located inside the chain conveyor 1, and its end is rotatably inserted into the inner wall of the chain conveyor 1. The body of the first drive rod 32 is rotatably mounted on the body of the first rotating rod 34, and the first drive rod 32 rotates about the first rotating rod 34 as an axis. One end of the first drive rod 32 is fixedly connected to the tube body of the second absorption tube 26, and the other end of the first drive rod 32 is fixedly mounted with a first counterweight 36. The weight of the second absorption tube 26 is greater than that of the first counterweight 36. A pressure block 38 is fixedly mounted on the bottom side of the support plate 2, and the pressure block 38 is used to press against the first counterweight 36.

[0050] Under the influence of gravity, the second absorption tube 26 rotates downwards, lowering its position below the first counterweight 36. As the chain conveyor 1 moves the support plate 2 to the position of the robot arm 10, the support plate 2 pushes the first counterweight 36, causing the second absorption tube 26 to rotate upwards and press against its bottom side. When the support plate 2 reaches the position of the robot arm 10, the pressure block 38 further pushes the first counterweight 36 downwards, causing the second absorption tube 26 to rotate upwards. This upward rotation of the second absorption tube 26 facilitates the entry of paint from the absorption hole 28 into its interior.

[0051] Reference Figure 7 , Figure 10 A first limiting rod 39 is fixedly installed on the body of the first drive rod 32, and a second limiting rod 40 is fixedly installed on the inner side of the chain conveyor 1. When the first counterweight 36 is not compressed and the second absorption tube 26 rotates downward, the first limiting rod 39 and the second limiting rod 40 engage with each other, thereby limiting the downward rotation angle of the second absorption tube 26 and facilitating the tilting state of the first drive rod 32. The tilting rotation of the first drive rod 32 facilitates the support plate 2 to push the first counterweight 36 to rotate.

[0052] Reference Figure 7 , Figure 10 The third absorption tube 27 is provided with a second drive rod 33 and a second rotating rod 35. The second rotating rod 35 is located inside the chain conveyor 1. The end of the second rotating rod 35 is rotatably inserted into the inner side wall of the chain conveyor 1. The rod body of the second drive rod 33 is rotatably installed on the rod body of the first rotating rod 34. The second drive rod 33 rotates around the second rotating rod 35 as an axis. One end of the second drive rod 33 is fixedly connected to the tube body of the third absorption tube 27. The other end of the second drive rod 33 is fixedly installed with a second counterweight 37. The weight of the third absorption tube 27 is less than that of the second counterweight 37.

[0053] When the support plate 2 moves to the position of the robot arm 10, under the gravity of the second counterweight 37, the third absorption tube 27 is on top and the second counterweight 37 is on the bottom, thus facilitating the entry of paint into the third absorption tube 27 from the absorption hole 28. After the coating of the sheet is completed, when the chain conveyor 1 moves the support plate 2 away from the position of the robot arm 10, the support plate 2 pushes the third absorption tube 27, causing the third absorption tube 27 to rotate and abut against the bottom side of the support plate, thus facilitating the chain conveyor 1 to transport the support plate 2 away from the position of the robot arm 10.

[0054] The implementation principle of the intelligent robot spraying device in this application embodiment is as follows: Based on the required size of the material to be sprayed, insert block 8 is inserted into slot 9, allowing shim block 7 to support the edge of the material. Then, support plate 2 is placed on chain conveyor 1. Chain conveyor 1 moves support plate 2 towards the position of robot arm 10. After limit block 21 enters limit groove 24, chain conveyor 1 stops transporting support plate 2, and support plate 2 moves to the position of robot arm 10, where first absorption pipe 25, second absorption pipe 26, and third absorption pipe 27 surround support plate 2.

[0055] When the support plate 2 moves to the position of the robot arm 10, the feeding mechanism 12 supplies paint to the spray nozzle 11. The robot arm 10 drives the spray nozzle 11 to move, thereby spraying the paint onto the plate. When it is necessary to spray the side of the plate away from the robot arm 10, the cylinder 16 extends and retracts, and the first motor 15 rotates, so that the side of the plate that was originally away from the robot arm 10 faces the robot arm 10. Then the robot arm 10 drives the spray nozzle 11 to spray the periphery of the plate, thereby reducing the occurrence of the spray nozzle 11 facing the robot arm 10, and thus reducing the occurrence of paint sticking to the robot arm 10.

[0056] During the spraying process of the board, the exhaust pump 29 is started, and the paint that is scattered in the air enters the first absorption pipe 25, the second absorption pipe 26 and the third absorption pipe 27 through the absorption hole 28 and then is discharged, thereby reducing the occurrence of paint sticking to the robot arm 10.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
