Description

Technical Field

[0001] The present invention relates to the technical field of automotive component processing, and specifically relates to a painting device for preparing automotive components. Background Art

[0002] As an important means of transportation, automobiles are characterized by convenience, flexibility, and comfort, and are of great significance to economic development, transportation, and social life. With the continuous progress of technology, the performance and functions of automobiles will continue to improve, bringing more convenience and comfort to people's travel and life.

[0003] Automobile parts are the individual units that make up an automobile, and they work together to ensure the normal operation of the automobile. During the preparation and processing of automobile parts, a painting device is required to paint the surface of the automobile parts. Painting of automobile parts is an important link in the automobile manufacturing and maintenance processes. It not only provides a beautiful appearance for the parts but also plays a protective role and extends the service life of the parts.

[0004] However, the existing processing equipment has the following deficiencies: In the prior art, such as the publication number CN110280419A, the present invention discloses a painting device for small arc-shaped automotive parts, including a device body. A painting rack is arranged on the upper part of the device body, a fixing rack is arranged below the painting rack, a mold is arranged on the upper part of the painting rack, fixing plates are arranged on both sides of the mold, first moving wheels are arranged below the fixing plates, a first gear is fixed on the first connecting rod below the first moving wheels, second connecting rods are arranged below the front and rear sides of the first connecting rod, the second connecting rods are fixed below on a spring tube, a fixing piece is arranged below the spring tube, a cavity is arranged inside the fixing piece, a motor box is arranged on the outer side of the fixing piece, a second moving wheel is arranged on the outer side of the motor box, and a spray gun is arranged on the inner side of the fixing piece. When painting small arc-shaped automotive parts, first place the corresponding mold on the painting rack, then fix the parts to be painted on the clamping piece, drive the second moving wheel, so that the painting device moves on the bottom plate, and at the mold, the spray gun automatically adjusts the painting distance and angle, so that the paint sprayed by the spray gun evenly covers the surface of the part. Painting is carried out manually with a spray gun, which not only wastes labor but also has low efficiency, and the painting quality also needs to be improved. Especially for small arc-shaped parts, it is impossible for manual operation to ensure that the distance between the nozzle and the automotive parts is the same each time when painting. When dealing with arc-shaped parts, it is even more difficult to make timely adjustments according to the deflection angle of the arc, resulting in low painting quality and the problem that the surface of the part cannot be evenly sprayed.

[0005] In the daily work, the inventor found that when the existing painting device for preparing automobile parts sprays paint on parts, the parts are transported to the lower part of the painting device, and then the paint is sprayed through the painting device to achieve the painting effect. However, during the painting process, excess paint will splash everywhere and is also likely to splash onto the parts waiting for processing, resulting in a large pollution area, which is not easy to clean up later. Moreover, the sprayed paint is not easy to collect, causing waste. At the same time, the overall painting device has the problem of single function, only having the painting effect.

[0039] Specifically, according to Figures 1-4 As shown: The auxiliary unit 7 includes a suction machine 71 which is installed on the surface of the transportation frame 1.

[0040] In this embodiment: During the process of protection and collection of the isolation cover 44, the suction machine 71 can suck the excess heat in the drying chamber 51 through the suction pipe 72 and discharge it into the hollow cavity 45 of the inner wall of the isolation cover 44 through the auxiliary pipe 73 and the supply air pipe 74. Thus, the hot air can heat the whole isolation cover 44, which is convenient for the paint to flow and be collected.

[0041] Specifically, according to Figure 5 As shown: The exhaust pipe 75 is in a bent state. The air outlet end of the exhaust pipe 75 is aligned with the lower surface of the isolation cover 44. Thus, the discharged hot air can also act on the isolation cover 44 to realize heating of the isolation cover 44.

[0042] The effects achieved by the entire mechanism are as follows: During the painting process, the painting unit 4, the drying unit 5, and the inspection unit 6 are operated in sequence. First, the parts to be painted can be placed on the anti-slip top columns 32 in the placement unit 3. Subsequently, the conveyor belt 2 can drive the T-shaped block 31, the anti-slip top columns 32, and the placed parts to move. When the parts reach below the spraying unit, first, two cylinders 43 can be opened. The cylinders 43 can drive the isolation cover 44 to move. The isolation cover 44 drives the slider 415 to move in the slide rail 414. When the two isolation covers 44 are fitted, the upper part of the T-shaped block 31, the anti-slip top columns 32, and the parts can be covered. Subsequently, the pump body 412 cooperates with the paint can 42 to transport the paint through the pipe body 411 to the spray head 47, and the spray head 47 performs the painting operation. During the painting process, the rotating motor 48 can drive the spray head 47 to rotate in the slide seat 46 to adjust the angle of the spray head 47. At the same time, when the control motor 49 drives the screw rod 410 to rotate, the screw rod 410 can drive the slide seat 46 and the spray head 47 to move, improving the flexibility of the spray head 47. During the process of the spray head 47, the excess raw materials will be sprayed in the isolation cover 44, reducing the phenomenon of paint splashing and subsequent inconvenience in cleaning. At the same time, since the lower part of the isolation cover 44 is inclined, the excess raw materials can flow into the collection pipe 4131 and finally be collected in the collection box 4132. During the collection process, the suction machine 71 in the auxiliary unit 7 can suck the excess heat in the drying chamber 51 through the suction pipe 72 and discharge it into the hollow cavity 45 on the inner wall of the isolation cover 44 through the auxiliary pipe 73 and the air supply pipe 74. Thus, the hot air can heat the entire isolation cover 44, facilitating the flowing and collection of the paint. When the exhaust pipe 75 in the bent state exhausts, the hot air can act on the isolation cover 44 to heat the isolation cover 44. When the painting is completed, the cylinder 43 drives the isolation cover 44 to reset, and the conveyor belt 2 continues to operate to drive the placement unit 3 to move, and another group of parts continues to be painted. The painted parts enter the drying chamber 51; After the painted parts enter the drying chamber 51, the cylinder 522 operates. The cylinder 522 can drive the baffle 521 to reset, so that the baffle 521 cooperates with the baffle curtain 53 for sealing. The hot air blower 58 can transport the hot air to the two cylindrical blowing heads 55 through the two connecting pipes 56, and the cylindrical blowing heads 55 blow and dry. During the drying process, the cylinder 573 can drive the rack 572 to move back and forth. The rack 572 cooperates with the gear 571 to drive the cylindrical blowing heads 55 to rotate and swing, thereby realizing multi-area blowing and drying of the parts. When the drying is completed, the placement unit 3 drives the parts to move out of the drying chamber 51; When the dried component moves below the detection camera 63, the detection camera 63 can take pictures for identification. When there are defects in the painted component, the fourth cylinder 621 operates. The fourth cylinder 621 extends to drive the mounting plate 622 and the two push rods 623 to move. The push rods 623 can push the component on the placement unit 3 away, and the material guide plate 64 can guide the component away. When the quality of the painted component is normal, it can operate normally for the blanking operation.
