[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1 As shown, a highly adaptable universal coating line includes: a circular conveyor line 1, on which several moving platforms 2 are mounted. Several sets of support mechanisms 3 are mounted on the moving platforms 2 to support the workpieces to be processed. The moving platforms 2 move cyclically along the circular conveyor line 1, driving the workpieces to be processed to achieve circular reciprocating motion.

[0036] Along the circular conveyor line 1 are a conveying mechanism 4, a painting mechanism 5, a drying mechanism 6, and a turning mechanism 7.

[0037] like Figures 2 to 4 As shown, the support mechanism 3 includes several support rods 31, arranged in pairs on the moving platform 2. A support block 32 is rotatably mounted on the top of each support rod 31. The support block 32 has a fan-shaped ring structure, with flexible support structures on both its top and bottom surfaces. The support block 32 is flipped via a rotating mechanism. Since the workpiece (car bumper) is generally arc-shaped, the shape requirements of the bottom support structure differ after flipping. To improve the stability of the support, the support block 32 adopts a fan-shaped ring structure.

[0038] Specifically, such as Figure 4 As shown, the flexible support structure includes slots, which are respectively formed on the top and bottom surfaces of the fan-ring structure support block 32. A plurality of support columns 33 are evenly arranged in the slots. The bottom of the support columns 33 is connected to the support block 32 by springs. The top surface of the support column 33 protrudes beyond the top / bottom surface of the support block 32. The outer contour of the workpiece to be processed is irregular in shape. The support columns 33 can extend and retract under the action of the springs to adapt to the outer contour of the workpiece, improving support stability and reducing damage to the car bumper.

[0039] Among them, such as Figure 3 As shown, the rotating mechanism includes a rotating groove 34, which is formed on the support rod 31. A support block 32 is rotatably mounted in the rotating groove 34 via a shaft. A first gear 35 is mounted at one end of the shaft, and a second gear 36 meshes with one side of the first gear 35. A first transmission rod 37 is positioned at the center of the second gear 36, and the first transmission rod 37 is arranged vertically downwards, with a third gear 38 fitted at its bottom. A fourth gear 39 meshes with one side of the third gear 38, and a second transmission rod 310 is positioned at the center of the fourth gear 39. The second transmission rod 310 extends towards another support rod 31 in the same group, and a fifth gear 311 is fitted at its end. The two fifth gears 311 corresponding to the two support rods 31 in the same group mesh with both sides of a sixth gear 312. An insertion port is formed at the center of the sixth gear 312, which is used for the insertion of the power mechanism of the rotating mechanism to achieve transmission.

[0040] The conveying mechanism 4 includes a conveying bracket 41 and a conveying clamp 42. The conveying clamp 42 is movably mounted on the conveying bracket 41 and is used for conveying the upper and lower support mechanism of the workpiece.

[0041] like Figure 5As shown, the painting mechanism 5 includes several painting robotic arms 51. Each painting robotic arm 51 includes a painting base 511, a painting mounting base 512, a first robotic arm 513, a second robotic arm 514, and a paint spray head 515. The painting base 511 is movably disposed on one side of the circular conveyor line 1 to adjust the position of the painting mechanism 5. The painting mounting base 512 is rotatably disposed on the top surface of the painting base 511. The bottom of the first robotic arm 513 is rotatably disposed on the side of the painting mounting base 512, and its top is rotatably connected to one end of the second robotic arm 514. The paint spray head 515 is disposed at the other end of the second robotic arm 514 and connected to a paint source. The painting robotic arms 51 drive the paint spray head 515 to move and achieve full-angle painting to adapt to the irregular external contours of the car bumper.

[0042] The drying mechanism 6 includes a drying insulated chamber 61, which is mounted on the circular conveyor line 1. The chamber's walls are made of insulating material to prevent excessive heat loss. Inside the drying insulated chamber 61 are heating devices and several drying robots 62. The heating devices heat the air inside the drying insulated chamber 61, and the drying robots 62 achieve precise drying.

[0043] Specifically, such as Figure 6 As shown, the drying robot 62 includes a drying base 621, a drying mounting base 622, a first drying robotic arm 623, a second drying robotic arm 624, and a drying head 625. The drying base 621 is movably mounted on one side of the circular conveyor line 1. The drying mounting base 622 is rotatably mounted on the top surface of the drying base 621. The bottom of the first drying robotic arm 623 is rotatably mounted on the side of the drying mounting base 622, and its top is rotatably connected to one end of the second drying robotic arm 624. The drying head 625 is located at the other end of the second drying robotic arm 624. The drying head 625 can blow hot air. The drying robot 62 can move the drying head 625 to precisely dry various positions on the car bumper. Combined with a heating device, this improves drying efficiency and prevents the paint in the corners and crevices of the car bumper from remaining undried.

[0044] The flipping mechanism 7 includes a flipping bracket 71, a flipping robotic arm 72, and a rotation mechanism power mechanism. The flipping robotic arm 72 is mounted on the flipping bracket 71 and can grip the workpiece to flip it, allowing its top and bottom surfaces to be interchanged for subsequent painting. The rotation mechanism power mechanism is mounted on the flipping bracket 71 and drives the rotation mechanism to move, thereby causing the support block 32 to move synchronously with the flipping robotic arm 72. Preferably, the rotation mechanism power mechanism is a drive rod, which is movably mounted on the flipping bracket 71. One end is connected to a drive device, and the other end is movably inserted into the center of the sixth gear 312 to engage with it and drive its rotation.

[0045] Among them, such as Figure 7As shown, the flipping robotic arm 72 includes a mounting plate 721, which is vertically and flexibly mounted on the flipping bracket 71 via a lifting device 722. A clamping cylinder 723 is mounted on the mounting plate 721, controlling the movement of two flipping clamping plates 724. A flipping mounting plate 725 is located at the end of each flipping clamping plate 724. A flipping clamping block 726 is located on the side of the flipping mounting plate 725 facing the other flipping mounting plate 725. The flipping clamping block 726 is driven by a flipping motor 7210 to rotate and flip the workpiece. The flipping motor 7210 is mounted on the flipping mounting plate 725.

[0046] Preferably, such as Figure 8 and Figure 9 As shown, the flipping clamp 726 is a flexible clamp with a groove on its clamping surface. Several clamping posts 72 are evenly arranged in the groove. The bottom end of the clamping post 727 is connected to the flipping clamp 726 by a spring. Furthermore, the clamping posts 727 have through slots 728. A limiting post 729 is fixedly installed in the groove of the flipping clamp 726. The limiting post 729 is inserted through the through slot 728 to limit the displacement limit of the clamping post 727.

[0047] Working process: The car bumper is picked up by the handling clamp 42 and transported to the moving platform 2, placed on the top surface of the support mechanism 3, and supported by the support block 32. The top surface of the support block 32 is in contact with the bottom surface of the car bumper. The moving platform 2 moves under the drive of the circular conveyor line 1 and moves to the painting mechanism 5. The painting robot arm 51 sprays paint on the top surface of the car bumper. After completion, it continues to move into the drying mechanism 6. Under the action of hot air in the drying heat insulation chamber 61 and the drying robot 62, it achieves rapid drying. Then it moves to the flipping mechanism. The flipping robot arm 72 descends and clamps the car bumper and then rises. Driven by the flipping motor 7210, the flipping clamp 726 rotates and flips the car bumper. At the same time, the power mechanism of the rotating mechanism inserts the sixth gear 312 to drive the support block 32 to flip. Then the flipping robot arm 72 descends and puts the car bumper back on the support mechanism 3. The moving platform 2 continues to move and starts the next round of painting and drying until the painting process is completed and the material is unloaded.

[0048] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
