Description

Technical Field

[0001] This utility model relates to the field of spraying technology, specifically to a metal fuel tank spraying line. Background Technology

[0002] The fuel tank is an important component of a car. According to the material, it can be divided into metal fuel tanks and plastic fuel tanks. Metal fuel tanks include iron fuel tanks, aluminum alloy fuel tanks, etc. Metal fuel tank spraying is an important surface treatment process in the production of metal fuel tanks, which aims to enhance the fuel tank's corrosion resistance, wear resistance and aesthetics.

[0003] Existing metal fuel tank coating lines typically use nozzles located at the top and sides of the coating mechanism to coat the sides and top of the metal fuel tank. The bottom and front / rear sides, which are in contact with the conveyor mechanism, cannot be coated. This requires manual adjustment of the fuel tank's position multiple times before coating, resulting in low production efficiency and hindering smooth assembly line production. Therefore, a new metal fuel tank coating line needs to be designed to address these issues. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-4 One embodiment provided by this utility model:

[0031] A metal fuel tank coating line, comprising:

[0032] The first equipment frame 1 is equipped with a first conveyor roller 2. A first spraying mechanism 3 is installed on one side of the top of the first equipment frame 1, and a first drying mechanism 4 is installed on the other side of the top of the first equipment frame 1. A three-section hydraulic rod 5 is rotatably installed at one end of the first equipment frame 1. The three-section hydraulic rod 5 is inclined and its length is not less than 2 / 3 of the side length of the flip plate 6. The above structural design enables the three-section hydraulic rod 5 to stably support the first vacuum suction cup 7 and to extend and drive the flip plate 6 to rotate at a sufficient angle.

[0033] The three-section hydraulic rod 5 is rotatably connected to the bottom surface of the tilting plate 6 at its top. The tilting plate 6 is L-shaped when viewed from the front. The top surface of the bottom of the tilting plate 6 is on the same horizontal plane as the top surface of the first conveying roller 2. The above structural design allows the first conveying roller 2 to smoothly convey the metal oil tank onto the tilting plate 6. The tilting plate 6 can stably support the metal oil tank. A first vacuum suction cup 7 is fixedly installed on the inner side of the tilting plate 6. The first vacuum suction cup 7 is evenly distributed on the inner bottom surface and inner vertical surface of the tilting plate 6. The end of the first vacuum suction cup 7 is flush with the inner bottom surface and inner vertical surface of the tilting plate 6. The above structural design allows the first vacuum suction cup 7 to stably adsorb the metal oil tank, so that the metal oil tank can stably rotate with the tilting plate 6. The tilting plate 6 is rotatably connected to the top of one end of the second equipment frame 9 through the rotating shaft 8 on the side. The second conveying roller 10 is installed on the other end of the second equipment frame 9.

[0034] The second equipment rack 9 has a second spraying mechanism 11 installed at the top center of the second equipment rack 9, and a second drying mechanism 12 installed at the other end of the top of the second equipment rack 9. A servo motor 13 is fixedly installed at the bottom of the second equipment rack 9 below the second spraying mechanism 11. A supporting hydraulic rod 14 is fixedly installed at the end of the top output shaft of the servo motor 13, and a turntable 15 is fixedly installed at the top of the supporting hydraulic rod 14.

[0035] In one embodiment, the second conveying rollers 10 are densely distributed at equal intervals, and the horizontal plane at the top of the second conveying rollers 10 is lower than the horizontal plane at the center of the rotating shaft 8. The above structural design enables the second conveying rollers 10 to stably support the metal oil tank sliding off the flipping plate 6 and facilitates manual operation to continue flipping the metal oil tank.

[0036] In one preferred embodiment, the diameter of the turntable 15 is not less than 2 / 3 of the diameter of the second conveying roller 10, and the second conveying roller 10 is symmetrically distributed about the turntable 15. The above structural design enables the turntable 15 to contact the bottom surface of the metal oil tank over a large area, ensuring stable rotation and normal operation of the second conveying roller 10.

[0037] In one embodiment, the center of the turntable 15 and the center of the second spraying mechanism 11 are on the same vertical plane, and the top surface of the turntable 15 and the top surface of the second conveying roller 10 are on the same horizontal plane. The above structural design enables the metal oil tank to be smoothly conveyed to the turntable 15 by the second conveying roller 10.

[0038] In one preferred embodiment, a second vacuum suction cup 16 is installed on the turntable 15, and the top surface of the second vacuum suction cup 16 is on the same horizontal plane as the top surface of the turntable 15. The above structural design can effectively improve the stability of the turntable 15 when it lifts the metal oil tank and drives the metal oil tank to rotate.

[0039] The working principle of this utility model is as follows: When using this device, first place the metal oil tank to be sprayed into... Figure 1 On the first conveyor roller 2 at the right end of the first equipment frame 1, the first conveyor roller 2 transports the metal oil tank into the first spraying mechanism 3. The internal layout of the first spraying mechanism 3 is similar to... Figure 4 The internal layout of the second spraying mechanism 11 is the same. It sprays the top and side surfaces of the outer side of the metal oil tank, and then the metal oil tank is conveyed by the first conveying roller 2 to the first drying mechanism 4 for drying.

[0040] After drying, the first conveyor roller 2 transports the metal oil tank to the tilting plate 6. The first vacuum suction cup 7 is activated, adsorbing and fixing the metal oil tank onto the tilting plate 6. The three-section hydraulic rod 5 is then extended, pushing the tilting plate 6 to rotate around the pivot 8. Figure 2 The state shown becomes Figure 3 In the state shown, the first vacuum suction cup 7 is stopped working, and the metal oil tank slides along the flip plate 6 toward the second conveying roller 10. At this time, the operator pushes the sliding metal oil tank from the side of the second equipment frame 9 to flip it toward the second spraying mechanism 11, so that the bottom surface that was not sprayed is facing up, that is, the metal oil tank is rotated 180° longitudinally.

[0041] The second conveyor roller 10 is started to transport the metal oil tank to the turntable 15 inside the second spraying mechanism 11. The second conveyor roller 10 is stopped. The second vacuum suction cup 16 is started to adsorb and fix the metal oil tank on the top surface of the turntable 15. The support hydraulic rod 14 is extended to slightly lift the turntable 15 and the metal oil tank, so that the bottom surface of the metal oil tank is separated from the top of the second conveyor roller 10. The servo motor 13 is started to drive the support hydraulic rod 14, the turntable 15 and the metal oil tank to rotate horizontally by 90° through the output shaft, so that the unsprayed front and rear sides are rotated to the sides. The support hydraulic rod 14 is shortened to drive the second vacuum suction cup 16 and the metal oil tank to move down and reset. The second spraying mechanism 11 is started to spray the remaining three unsprayed sides. After the spraying is completed, the second conveyor roller 10 is started to transport the metal oil tank to the second drying mechanism 12 for drying. After drying, it is discharged.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
