Technical Field

[0001] This application relates to the field of automotive parts processing technology, and in particular to a robotic automated painting production line for passenger vehicle exterior parts. Background Technology

[0002] Automotive parts are the various units that make up a car and the products that serve the car.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0032] This utility model provides, for example Figure 1-4 The illustrated automated robotic painting production line for passenger vehicle exterior parts includes a placement plate 1, a mounting block 2 on the top surface of the placement plate 1, two conveyor belts 3 rotatably mounted on the outside of the mounting block 2, several gears 4 on the outside of the conveyor belts 3, a rack 5 on the top surface of the mounting block 2, the gears 4 meshing with the rack 5, a robotic arm 6 fixedly connected to the top surface of the placement plate 1, a spray nozzle 7 fixedly connected to one end of the robotic arm 6, and a fixing component on the bottom surface of the gears 4 for fixing the gears 4.

[0033] In this system, by setting up a placement plate 1, after the worker places the placement plate 1 in a suitable position, a fixing component is used to fix the gear 4 to the outside of the conveyor belt 3, so that the conveyor belt 3 can drive the gear 4 to move when it rotates. After the worker fixes the car parts to be sprayed on the top surface of the gear 4, the conveyor belt 3 can drive the car parts to move through the gear 4. By meshing the gear 4 with the rack 5, the gear 4 can drive the car parts to rotate when the conveyor belt 3 drives the car parts to move through the gear 4. At the same time, by feeding the spraying material into the inside of the spray nozzle 7, and by adjusting the position of the spray nozzle 7 through the robotic arm 6, the different directions of the car parts can be adjusted, so as to achieve spraying of the car parts without dead angles and improve the spraying quality of the car parts.

[0034] The fixing component includes a fixing rod 8, which is fixedly connected to the bottom end of the gear 4. A connecting rod 9 is movably sleeved on the outside of the fixing rod 8. The bottom end of the connecting rod 9 is fixedly connected to the top surface of the conveyor belt 3. A limiting groove 10 is opened on the inner wall surface of the connecting rod 9. A limiting ring 11 is fixedly connected to the outer wall surface of the fixing rod 8. The limiting ring 11 is movably sleeved with the limiting groove 10.

[0035] In this design, by setting a limiting ring 11, which is movably fitted together with the limiting groove 10, the limiting ring 11 can limit the fixed rod 8, thereby preventing the fixed rod 8 from moving out of the interior of the connecting rod 9.

[0036] Two rotating rollers 12 are rotatably installed inside the mounting block 2. The rotating rollers 12 are rotatably installed together with the conveyor belt 3. Two brackets 13 are fixedly connected to the bottom surface of the placement plate 1. The bottom surface of the brackets 13 is fixedly connected to the top surface of the placement plate 1.

[0037] When the rotating roller 12 rotates inside the mounting block 2, it can drive the conveyor belt 3 to rotate.

[0038] Two positioning blocks 14 are fixedly connected to the bottom surface of the rack 5. Two positioning grooves 15 are opened on the top surface of the placement plate 1. The positioning blocks 14 and the positioning grooves 15 are movably fitted together. A rotating hole 16 is opened on the bottom surface inside the positioning groove 15. An adjusting rod 17 is rotatably installed inside the rotating hole 16. The outer wall surface of the adjusting rod 17 is threaded. An adjusting groove 18 is opened on the bottom surface of the positioning block 14. The inner wall surface of the adjusting groove 18 is threaded. The adjusting rod 17 is threadedly connected to the adjusting groove 18.

[0039] The positioning block 14 is set so that the position of the rack 5 can be adjusted after the positioning block 14 moves inside the positioning groove 15, which makes it easier to mesh or separate the rack 5 from the gear 4 later.

[0040] Two sliding grooves 19 are provided on the top surface of gear 4. A sliding block 20 is slidably installed inside the sliding groove 19. A pressing plate 21 is fixedly connected to the top surface of the sliding block 20.

[0041] By adjusting the positions of the two extrusion plates 21, the two extrusion plates 21 can be used together to fix the car parts to the top surface of the gear 4.

[0042] A spring 22 is fixedly connected to one side of the sliding groove 19. One end of the spring 22 is fixedly connected to one side of the sliding block 20. A threaded hole is opened on the top surface of the sliding block 20. A bolt 23 is threadedly connected inside the sliding block 20.

[0043] By adjusting the position of bolt 23, when the bottom end of bolt 23 is in contact with the bottom surface inside the sliding groove 19, the sliding block 20 can be fixed inside the sliding groove 19.

[0044] Working Principle: When this robotic automatic painting production line for passenger vehicle exterior parts is in use, a placement plate 1 is set up. After the operator places the placement plate 1 in a suitable position, a fixing component is used to fix the gear 4 to the outside of the conveyor belt 3. This allows the conveyor belt 3 to rotate and drive the gear 4 to move. When the operator fixes the car parts to be painted onto the top surface of the gear 4, the conveyor belt 3 can move the car parts through the gear 4. By meshing the gear 4 with the rack 5, the gear 4 can drive the car parts to rotate while the conveyor belt 3 moves through the gear 4. At the same time, the paint material is delivered to the inside of the nozzle 7, and the position of the nozzle 7 is adjusted by the robotic arm 6 to adjust the different directions of the car parts during painting, achieving paint coverage without dead angles and improving the painting quality of the car parts.

[0045] By setting the positioning block 14, the position of the rack 5 can be adjusted after the positioning block 14 moves inside the positioning groove 15, so that the rack 5 can be engaged or disengaged from the gear 4 later. By adjusting the position of the two pressing plates 21, the two pressing plates 21 can be used together to fix the car parts on the top surface of the gear 4. By adjusting the position of the bolt 23, when the bottom end of the bolt 23 is in contact with the bottom surface inside the sliding groove 19, the sliding block 20 can be fixed inside the sliding groove 19.

[0046] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
