DETAILED DESCRIPTION

[0030] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the present application will be described clearly and completely below in combination with embodiments. ​​​

[0031] Example

[0032] This invention provides an automotive paint booth with a track-mounted painting robot, such as... Figures 1 to 4 As shown, the system includes a spray booth 1, a robot body 2, a lifting frame 10, and a cover plate 23. A guide rail 7 is fixedly connected to one side of the bottom of the inner wall of the spray booth 1. The robot body 2 is slidably installed within the guide rail 7. A power source is installed on the robot body 2, enabling it to move within the guide rail 7 and perform spraying operations. A spray pipe 39 is installed on one side of the robot body 2. Electric telescopic rods 8 are fixedly connected to both sides of the top of the spray booth 1. A connecting plate 9 is fixedly connected to the output end of each electric telescopic rod 8. The connecting plate 9 is driven to descend synchronously by the two electric telescopic rods 8. Square slots are connected to both sides of the top of the lifting frame 10. The connecting plate 9 is slidably installed within these slots. The electric telescopic rods 8 drive the connecting plate 9 to descend, thus enabling the lifting frame 10 to descend synchronously. A drying mechanism 11 is installed on the same side of the lifting frame 10. 11. The paint is dried. The drying mechanism 11 consists of standard parts or components known to those skilled in the art. Its structure and principle are known to those skilled in the art through technical manuals or conventional experimental methods. Rollers 12 are provided on both sides of the lifting frame 10. Concave frames 13 are fixedly connected to both sides of the inner wall of the spray booth 1 below the rollers 12. When the lifting frame 10 descends, the rollers 12 will contact the concave frames 13, so that the lifting frame 10 moves synchronously with the robot body 2 through the rollers 12. A locking mechanism is provided at the bottom of the lifting frame 10, which enables the drying mechanism 11 to move synchronously with the robot body 2. An air circulation mechanism is provided inside the spray booth 1 to maintain airflow inside the spray booth 1. Blocking blocks 37 are fixedly connected to both sides of the top of the inner wall of the spray booth 1. There are several blocking blocks 37 (e.g., ...). Figure 9As shown), several blocking blocks 37 prevent the lifting frame 10 from moving back and forth when not in use. The opposite face of each blocking block 37 contacts the lifting frame 10. An arc-shaped block 38 is inserted into the bottom end of each blocking block 37 near the lifting frame 10. When the lifting frame 10 descends, it contacts the arc-shaped block 38 and pushes it backward. The arc-shaped block 38 is reset by a third spring. A third spring is fixedly connected between one side of each arc-shaped block 38 and the blocking block 37. A door is provided on one side of the spray booth 1. There are two sets of rollers 12, two in each set. The drying mechanism 11 is in the shape of an inverted concave shape. The surface of the mechanism 11 is connected with several air nozzles. When in use, the door of the paint booth 1 is opened first, then the car is parked inside the paint booth 1 and the door is closed. At this time, the electric telescopic rod 8 drives the connecting plate 9 to descend, which in turn allows the lifting frame 10 to descend synchronously, so that the locking mechanism at the bottom of the lifting frame 10 locks with the robot body 2. At this time, the robot body 2 is moved in the guide rail 7 by the power source and paints the car through the paint spray pipe 39. At the same time as the paint is being sprayed, the drying mechanism 11 will also operate synchronously, and hot air will be sprayed out through the air nozzles on the drying mechanism 11 to quickly dry the paint on the car.

[0033] like Figure 5 As shown, the engaging mechanism includes: a locking block 15; a fixing block 14 is fixedly connected to one side of the robot body 2; a locking groove is formed at the top of the fixing block 14; the locking block 15 is fixedly installed on the lifting frame 10 and located directly above the locking groove; extension blocks 16 are inserted into the bottom ends of both sides of the locking block 15; a fourth spring (not shown in the figure) is fixedly connected between the extension blocks 16 and the locking block 15; when the lifting frame 10 descends, it will cause the locking block 15 to descend and contact the locking groove; at this time, the extension blocks 16 on both sides of the locking block 15 will be squeezed and retracted into the locking block 15; after the locking block 15 is fully engaged with the locking groove, the extension blocks 16 on both sides will be reset by the reaction force of the fourth spring (e.g., Figure 11 (As shown).

[0034] like Figures 6 to 7As shown, horizontal plates 17 are slidably connected to both sides of the inner wall of the spray booth 1. One side of each horizontal plate 17 is slidably connected to the bottom end of the lifting frame 10. The two ends of the sliding connection between the bottom end of the lifting frame 10 and the horizontal plate 17 are open. Lifting blocks 18 are slidably connected to both sides of the inner wall of the spray booth 1. Long plates 19 are rotatably connected to both sides of the inner wall of the spray booth 1. The two ends of each long plate 19 are rotatably connected to the lifting block 18 and the horizontal plate 17, respectively. When the lifting frame 10 descends, it also drives the horizontal plate 17 to descend. At this time, the horizontal plate 17 will squeeze one end of the long plate 19 to make it descend, while the other end of the long plate 19 will lift the lifting block 18 upward. The two sides of the inner wall of the spray booth 1, located directly opposite the horizontal plate 17, are connected to the lifting block 18. Each of the four sections has a movable slot at the bottom, and a limit block 20 is slidably connected inside each movable slot. As the horizontal plate 17 descends, it also presses against the limit block 20, causing it to move backward. When the horizontal plate 17 moves below the limit block 20, the limit block 20 resets due to the reaction force of the second spring, blocking the horizontal plate 17. The horizontal plate 17 only rises when the lifting frame 10 returns to its original position. A second spring is fixedly connected to one side of each limit block 20 and the movable slot. Two sets of cylinders 40 are provided on both sides of the top of the spray booth 1, with four cylinders in each set. Two sets of winding wheels 21 are slidably connected to both sides of the top of the spray booth 1, with two winding wheels in each set. Each set of cylinders 40... Ropes 22 are wound and connected to the winding reel 21. One end of the rope 22 is fixedly installed on the lifting block 18, and the cover plate 23 is located directly below the other end of the rope 22. When the lifting block 18 rises, the ropes 22 at both ends will slacken, and the cover plate 23 will descend under its own weight. Airbags 24 are fixedly connected to the opposite surfaces of the two cover plates 23. Multiple suction cups 25 are fixedly connected to the opposite surfaces of the two cover plates 23 and between the airbags 24. Each cover plate 23 is inclined, and each opposite surface of each cover plate 23 is equipped with an infrared sensor (not shown in the figure). The length of the suction cup 25 is greater than that of the airbag 24. The airbag 24 is ring-shaped, and each opposite surface of each cover plate 23 is equipped with an iron plate. The iron sheet is attracted to the magnet 36. As the lifting frame 10 descends, it also drives the horizontal plate 17 to descend. At this time, the horizontal plate 17 will squeeze one end of the long plate 19 to make it descend, while the other end of the long plate 19 will lift the lifting block 18. When the lifting block 18 rises, the ropes 22 at both ends will loosen. At this time, the two cover plates 23 descend to the front and rear windows of the car by their own weight. At this time, the suction cup 25 will first contact the car glass. As the cover plate 23 descends, the air in the suction cup 25 will be expelled, thus fixing the cover plate 23 to the car glass. The airbag 24 can block the gap between the car glass and the cover plate 23, so that the paint will not fall into the car glass during painting.

[0035] like Figures 7 to 8As shown, a servo motor 26 is fixedly connected to one side of the top of the inner wall of the spray booth 1. The servo motor 26 starts simultaneously with the descent of the cover plate 23. Two sets of positive and negative threaded rods 27 are rotatably connected to the top of the inner wall of the spray booth 1. The threads on both sides of the positive and negative threaded rods 27 are arranged in opposite directions. The servo motor 26 drives one of the positive and negative threaded rods 27 to rotate in both directions, and the other positive and negative threaded rod 27 rotates via a belt drive. This causes the two sets of winding wheels 21 to move in opposite directions. The two sets of positive and negative threaded rods 27 are connected by a belt drive. One end of the forward and reverse threaded screw 27 is fixedly connected to the output end of the servo motor 26. The winding wheel 21 is threaded onto the forward and reverse threaded screw 27. Each cover plate 23 has a groove on its opposite side. A semi-circular ring 28 is fixedly connected to both ends of each groove. A connecting rod 29 is fixedly connected to both sides of the other end of each rope 22. A hook 30 is rotatably connected to one side of each connecting rod 29. Each hook 30 is in contact with the semi-circular ring 28. After the cover plate 23 is fixed to the car glass, the forward and reverse threaded screw 27 is driven by the servo motor 26 to make the winding wheel 21... Moving in the opposite direction causes the bottom connecting rod 29 to move the hook 30 backward, separating it from the semicircular ring 28, and moving it to the edge of the spray booth 1, thus not obstructing the operation of the robot body 2 and the drying mechanism 11. A square plate 31 is fixedly connected between the opposite faces of each set of winding wheels 21. As the winding wheels 21 move, they also move the square plates 31. A rectangular block 32 is fixedly connected to the bottom of each square plate 31. A slider 33 is slidably connected inside each rectangular block 32. A limit post 34 is fixedly connected to the bottom of each slider 33. Each limiting post 34 has a first spring 35 fitted onto its surface, and a magnet 36 is rotatably connected to the bottom end of each limiting post 34. The magnet 36 contacts the top end of the cover plate 23. As the cover plate 23 descends, it also drives the limiting post 34 to descend. The limiting post 34 prevents the cover plate 23 from wobbling as it descends, thus ensuring accurate contact with the car glass. After descending to a certain height, the rectangular block 32 is blocked, causing the limiting post 34 to stop descending and the magnet 36 to separate from the cover plate 23. At this point, the first spring 35 drives the limiting post 34 to reset.

[0036] like Figure 10As shown, the air circulation mechanism includes: a blower 3 and an exhaust fan 6. The interior of the spray booth 1 has a first cavity and a second cavity. The blower 3 is fixedly installed on one side of the spray booth 1. An air inlet pipe is connected to the top of the blower 3, allowing air to enter the interior of the blower 3 through the air inlet pipe and then enter the first cavity. The blower 3 is connected to the first cavity. A top cotton 4 is installed at the top of the inner wall of the spray booth 1, allowing air to come into contact with the top cotton 4 and be filtered by the top cotton 4, so that clean air enters the interior of the spray booth 1. A ventilation groove is connected between the bottom of the inner wall of the spray booth 1 and the second cavity. An environmental protection cabinet 5 is fixedly connected to the bottom of the outer wall of the other side of the spray booth 1. The exhaust fan 6 is fixedly installed inside the environmental protection cabinet 5, and an exhaust pipe is fixedly connected to the top of the environmental protection cabinet 5. The exhaust fan 6 draws air from the interior of the spray booth 1 into the environmental protection cabinet 5 through the ventilation groove and then exhausts it through the exhaust pipe, thus ensuring air circulation inside the spray booth 1.

[0037] Working principle: In use, first open the door of the paint booth 1, then park the car inside the paint booth 1 and close the door. At this time, the electric telescopic rod 8 drives the connecting plate 9 to descend, which in turn causes the lifting frame 10 to descend synchronously, so that the locking mechanism at the bottom of the lifting frame 10 engages with the robot body 2. As the lifting frame 10 descends, it also drives the horizontal plate 17 to descend. At this time, the horizontal plate 17 will squeeze one end of the long plate 19 to make it descend, while the other end of the long plate 19 will lift the lifting block 18. When the lifting block 18 rises, the ropes 22 at both ends will loosen. At this time, it will descend onto the front and rear windows of the car by the weight of the two cover plates 23. At this time, the suction cup 25 will first contact the car windows. As the cover plates 23 descend, the air in the suction cup 25 will be expelled. The cover plate 23 is fixed to the car glass, and the airbag 24 can block the gap between the car glass and the cover plate 23. When the cover plate 23 descends, the servo motor 26 will start and drive one of the forward and reverse threaded rods 27 to rotate in both directions. The other forward and reverse threaded rod 27 will rotate through the belt drive, so that the two sets of winding wheels 21 can move in opposite directions. The cover plate 23 is adjusted according to the position of the car glass so that the cover plate 23 can accurately fit the car glass. At this time, the robot body 2 moves in the guide rail 7 through the power source and sprays paint on the car through the paint spray pipe 39. At the same time as spraying paint, the drying mechanism 11 will also operate synchronously. Hot air is sprayed out through the air nozzle on the drying mechanism 11 to quickly dry the paint on the car.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
