Description
Technical Field
[0001] This utility model relates to the field of automobile cover plate production technology, and in particular to a uniform spraying device for automobile cover plate production. Background Technology
[0002] Car covers are an important component of a car body, typically referring to engine covers, trunk covers, door covers, fenders, and other parts. Car covers protect the engine, items in the trunk, and various internal components. During the production process, car covers are coated to form a protective film on the surface, isolating air and moisture and preventing chemical reactions between the metal and external substances, thus extending the lifespan of the car cover. The coating also possesses a certain degree of hardness and toughness, resisting wear and tear from external forces and maintaining the integrity and smoothness of the cover surface. Furthermore, the coating usually contains UV-resistant additives, effectively blocking ultraviolet radiation and slowing down material aging.
[0003] During the car cover painting process, the car cover is sprayed by a spraying device. The moving mechanism drives the spray gun to move at a constant speed, so that the spray gun sprays the paint onto the car cover. Moreover, the constant speed movement ensures that the spray gun sprays the paint evenly onto the car cover.
[0004] However, when the spraying device uniformly sprays paint onto the car cover, the different shapes and materials of the car cover result in different car cover requiring different spray guns to spray paint at different angles. Using a single spray angle will lead to uneven spraying on different car cover, resulting in different spraying devices being needed for different car cover. Based on the above problems, this application proposes a uniform spraying device for the production of car cover. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a uniform spraying device for automobile cover plate production, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A uniform spraying device for automobile cover plate production includes a spraying box, a placement platform fixedly disposed inside the spraying box, a moving component disposed on the top of the placement platform, a mounting housing disposed on the top of the placement platform via the moving component, a driving component disposed inside the mounting housing, a mounting shaft rotatably disposed inside the mounting housing, a fixing sleeve fixedly disposed on the surface of the mounting shaft, a connecting column fixedly disposed at the bottom of the fixing sleeve, a mounting frame fixedly disposed at the bottom end of the connecting column, a spray gun fixedly disposed inside the mounting frame, and an angle adjustment detection component disposed at the left end of the mounting shaft.

[0009] Preferably, the drive assembly includes a drive motor fixedly mounted on the rear side of the mounting housing, a worm gear fixedly mounted at the output end of the drive motor, a worm wheel meshing on the surface of the worm gear, a rotating shaft fixedly mounted inside the worm wheel, the rotating shaft being rotatably mounted inside the mounting housing, and the left end of the rotating shaft being connected to the right end of the mounting shaft.
[0010] Preferably, the angle adjustment detection component includes an encoder fixedly installed inside the mounting housing, a coupling fixedly provided at the detection end of the encoder, a connecting rod fixedly provided inside the coupling, and the connecting rod fixedly installed at the left end of the mounting shaft.
[0011] Preferably, there are two linear motors and two mounting plates, and the two linear motors and two mounting plates are symmetrically distributed.
[0012] Preferably, both the worm and the worm wheel are installed inside the housing, and both the worm and the worm wheel are made of metal.
[0013] Preferably, the spray box has a door installed on the front side via a hinge, and an observation window is fixedly installed inside the door. The observation window is colorless and transparent.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This uniform spraying device for automobile cover plate production drives the mounting shaft to rotate through the drive component, so that the fixed sleeve drives the spray gun to rotate through the connecting column and the mounting frame, thereby adjusting the spraying angle of the spray gun. Moreover, the angle adjustment detection component can detect the angle of the spray gun rotation, making the adjustment angle more precise. This allows the spraying device to be applicable to the spraying needs of automobile cover plates of different shapes and materials, avoiding the use of a single spraying angle, which would lead to uneven spraying of different automobile cover plates, and avoiding the need to use different spraying devices for different automobile cover plates.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0021] Reference Figure 1-4A uniform spraying device for automobile cover production includes a spraying box 1, a placement platform 2 fixedly disposed inside the spraying box 1, a moving component disposed on the top of the placement platform 2, a mounting housing 8 disposed on the top of the placement platform 2 via the moving component, a driving component disposed inside the mounting housing 8, a mounting shaft 13 rotatably disposed inside the mounting housing 8, a fixing sleeve 14 fixedly disposed on the surface of the mounting shaft 13, a connecting post 15 fixedly disposed at the bottom of the fixing sleeve 14, and a mounting frame 16 fixedly disposed at the bottom end of the connecting post 15. The mounting frame 16 is internally fixed... A spray gun 17 is provided. An angle adjustment and detection component is provided at the left end of the mounting shaft 13. The drive component includes a drive motor 9 fixedly mounted on the rear side of the mounting housing 8. A worm gear 10 is fixedly mounted at the output end of the drive motor 9. A worm wheel 11 is meshed on the surface of the worm gear 10. Both the worm gear 10 and the worm wheel 11 are inside the mounting housing 8. Both the worm gear 10 and the worm wheel 11 are made of metal. A rotating shaft 12 is fixedly mounted inside the worm wheel 11. The rotating shaft 12 is rotatably mounted inside the mounting housing 8. The left end of the rotating shaft 12 is connected to the mounting shaft 17. The right end of 3 is connected to the angle adjustment detection component, which includes an encoder 18 fixedly installed inside the mounting housing 8. A coupling 19 is fixedly installed at the detection end of the encoder 18, and a connecting rod 20 is fixedly installed inside the coupling 19. The connecting rod 20 is fixedly installed at the left end of the mounting shaft 13. The drive motor 9 drives the rotating shaft 12 to rotate through the worm gear 10 and worm wheel 11, which causes the mounting shaft 13 to drive the fixed sleeve 14 to rotate. The fixed sleeve 14 drives the spray gun 17 to rotate through the connecting column 15 and the mounting frame 16. Moreover, the mounting shaft 13 drives the detection end of the encoder 18 to rotate through the connecting rod 20 and the coupling 19. The angle of rotation of the mounting shaft 13 is detected by the encoder 18, which is the rotation angle of the spray gun 17. The angle of the spray gun 17 can be adjusted according to the material and shape of the car cover, so that the spraying device can be used for the spraying needs of car covers of different shapes and materials. This avoids the situation where a single spraying angle is used, which leads to uneven spraying of different car covers, and avoids the situation where different spraying devices are needed for different car covers.
[0022] Specifically, the moving component includes a linear motor 3 fixedly mounted on the top of the spray box 1. A moving base is mounted on the linear motor 3, and a mounting plate 4 is fixedly mounted on the top of the moving base. There are two linear motors 3 and two mounting plates 4, and they are symmetrically distributed. A second linear motor 5 is fixedly mounted between the facing surfaces of the mounting plates 4. A second moving base is mounted on the second linear motor 5, and an L-shaped mounting plate 6 is fixedly mounted on the front side of the second moving base. A hydraulic push rod 7 is fixedly mounted on the top of the L-shaped mounting plate 6. A mounting housing 8 is fixedly mounted on the output end of the hydraulic push rod 7. The car cover to be sprayed is placed on the top of the placement platform 2, and the box door 21 is closed. The paint is then conveyed to the spray gun 17 via an external conveying device. The paint is sprayed onto the car cover using a spray gun 17. A linear motor 3 drives a moving seat 1 to move a mounting plate 4, which in turn drives a linear motor 5 to move an L-shaped mounting plate 6 via the moving seat 2. A hydraulic push rod 7 moves a mounting housing 8, which in turn moves a fixing sleeve 14 via a mounting shaft 13. A connecting column 15 moves the spray gun 17 via a mounting frame 16. The linear motor 5 then drives the moving seat 2 to move the L-shaped mounting plate 6, which in turn moves the hydraulic push rod 7 via the mounting housing 8 to move the mounting shaft 13. The fixing sleeve 14 then moves the spray gun 17 via the connecting column 15 and the mounting frame 16, thus uniformly spraying different areas of the car cover.
[0023] Specifically, a door 21 is installed on the front side of the spray box 1 via a hinge. An observation window 22 is fixedly installed inside the door 21. The observation window 22 is colorless and transparent. The spray box 1 can be sealed through the door 21 and the observation window 22, and the spraying condition of the car cover can be observed through the observation window 22.
[0024] This uniform spraying device for automobile cover production is connected to 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.
[0025] In use: The drive motor 9 drives the output end to rotate the worm gear 10, which in turn drives the meshing worm wheel 11 to rotate. The worm wheel 11 then drives the rotating shaft 12 to rotate inside the mounting housing 8, causing the rotating shaft 12 to rotate the mounting shaft 13. The mounting shaft 13 then drives the fixing sleeve 14 to rotate, which in turn drives the connecting column 15 to rotate. The connecting column 15 drives the spray gun 17 to rotate via the mounting frame 16, thereby adjusting the spraying angle of the spray gun 17. When the mounting shaft 13 rotates, it drives the connecting rod 20 to rotate, which in turn drives the encoder 18 to rotate via the coupling 19. The encoder 18 detects the rotation angle of the mounting shaft 13, which in turn detects the rotation angle of the spray gun 17 driven by the fixing sleeve 14 through the connecting column 15 and the mounting frame 16. Therefore, the angle of the spray gun 17 can be adjusted according to the material and shape of the car cover.
