Description

Technical Field

[0001] This utility model relates to the field of automotive processing technology, specifically to an automotive painting equipment with controllable spraying range. Background Technology

[0002] Painting is an essential process in the manufacturing of automotive parts. It can change the appearance of a car and also prevent rust.

[0003] The existing patent document CN221208611U discloses a paint spraying device for automotive processing with controllable spraying range. This paint spraying device for automotive processing with controllable spraying range uses a first motor, a first threaded rod, a moving rod, a second motor, a second threaded rod, a moving block, an electric cylinder, a third motor, and a spray gun in cooperation. When the first motor is working, it drives the first threaded rod to rotate. The rotation of the second threaded rod drives the moving plate to move back and forth. When the second motor is working, it drives the second threaded rod to rotate. The rotation of the second threaded rod drives the moving block to move left and right. When the electric cylinder is working, it drives the third motor to move up and down. When the third motor is working, it drives the spray gun to rotate. Through the above design, the spray gun can move back and forth, left and right, and up and down, as well as rotate itself, which facilitates the movement of the spray gun to any position and multi-angle spraying.

[0004] However, existing automotive painting equipment with controllable spray range is not convenient for flexibly adjusting the nozzle diameter according to processing needs. This is insufficient when facing the diverse painting requirements of automotive parts. For example, some small and complex parts in the engine compartment require a very small nozzle diameter for precise painting to avoid accidentally spraying paint onto surrounding areas that do not need painting. On the other hand, when painting large flat areas of the car body, a larger nozzle diameter can significantly improve painting efficiency. However, existing equipment cannot quickly and conveniently switch between these two needs. When painting automotive parts made of different materials, the requirements for paint atomization and spray flow vary, and the nozzle diameter is a key parameter affecting these factors. For example, plastic parts may require a finer paint mist to ensure paint adhesion. For smoothness and evenness, a smaller nozzle diameter is needed. However, when painting metal parts for rust prevention, a larger nozzle diameter is sometimes required to ensure sufficient paint supply in order to achieve a certain paint film thickness. Due to the inconvenience of adjusting the nozzle diameter of existing equipment, operators often need to frequently change different specifications of spray guns, which not only consumes a lot of time and energy, but also easily introduces impurities during the replacement process, affecting the painting quality. Moreover, in the actual painting process, as the painting task progresses, it may be necessary to adjust the nozzle diameter in real time according to the unevenness and curve changes of the part surface to ensure uniform paint coverage. However, the fixed nozzle diameter of existing equipment obviously cannot meet the needs of this dynamic change, resulting in local paint thickness being too thick or too thin in the painting of complex-shaped parts, which seriously affects the appearance quality and protective performance of automotive parts.

[0017] 1. This automotive painting equipment with controllable spray range features an adjustable motor and hollow baffles. When the motor operates, it drives a cross-shaped adjustment frame to rotate, allowing four hollow baffles of different inner diameters to rotate sequentially to positions corresponding to the nozzles. Operators can select the appropriate inner diameter baffle to control the spray range based on actual painting needs. For example, when performing fine painting on small automotive parts, using a smaller inner diameter baffle effectively limits the spray area, preventing paint from splashing onto areas that don't need painting and improving accuracy. When painting large automotive parts, a larger inner diameter baffle can be switched to meet the painting needs of a larger area and improve painting efficiency.

[0026] An adjusting motor 5 is installed above the paint pump 3. A cross-shaped adjusting bracket 6 is fixedly connected to the transmission end of the adjusting motor 5. Four hollow baffles 7 with different inner diameters are installed on the outside of the cross-shaped adjusting bracket 6. The hollow baffles 7 correspond to the nozzles 4. A drive mechanism 8 is installed above the paint spraying station 1, and an auxiliary mechanism 9 is installed on one side of the mounting plate 2. During the painting process, if the spraying range needs to be changed, the adjusting motor 5 is started. The transmission end of the adjusting motor 5 drives the cross-shaped adjusting bracket 6 to rotate, and the four hollow baffles 7 with different inner diameters on the outside of the cross-shaped adjusting bracket 6 rotate accordingly. The operator can rotate the hollow baffle 7 with the appropriate inner diameter to the position corresponding to the nozzle 4 according to the actual painting needs, thereby controlling the spraying range of the paint. For example, when painting the delicate parts of automotive components, a hollow baffle 7 with a smaller inner diameter is selected to limit the paint spraying area and prevent paint from splashing onto the surrounding areas that do not need to be painted; when painting a large area, switch to a hollow baffle 7 with a larger inner diameter to improve painting efficiency.

[0027] The drive mechanism 8 includes a first motor 801, which is fixedly mounted on the upper surface of the spray booth 1. A placement platform 802 is fixedly connected to the transmission end of the first motor 801. A protective plate 803 is fixedly installed on one side of the upper surface of the spray booth 1. A gantry frame 804 is fixedly installed on the side of the upper surface of the spray booth 1 away from the protective plate 803. A first mounting slot 805 is fixedly installed on one side of the gantry frame 804. A second motor 806 is fixedly mounted at the top of the first mounting slot 805. A threaded rod 807 is fixedly connected to the transmission end of the bottom of the second motor 806. The end of the threaded rod 807 away from the second motor 806 is connected to the first mounting slot 805 via a bearing. A moving block 808 is threadedly connected to the outer surface of the threaded rod 807. The two sides of block 808 are fully fitted with the first mounting slot 805. The movable block 808 is fixedly connected to the mounting plate 2. The auxiliary mechanism 9 includes a connecting block 901, which is fixedly connected to the side of the mounting plate 2 away from the movable block 808. The gantry 804 is fixedly provided with a second mounting slot 902 on the side away from the first mounting slot 805. A vertical rod 903 is fixedly provided inside the second mounting slot 902. The connecting block 901 is slidably connected to the vertical rod 903. A material pipe 904 is provided on one side of the paint pump 3. A connecting plate 905 is fixedly connected to the middle of the upper surface of the mounting plate 2. The adjusting motor 5 is located on one side of the connecting plate 905. A sealing gasket 906 is provided at the end of the nozzle 4 away from the paint pump 3. This device is used for processing automotive parts. During the painting operation, the worker first places the car parts to be painted on the placement platform 802, starts the first motor 801, and its transmission end drives the placement platform 802 to rotate, which can adjust the angle of the car parts to facilitate painting operations on different parts. Next, if it is necessary to adjust the painting position, the second motor 806 is started. The transmission end of the second motor 806 drives the threaded rod 807 to rotate. Since the moving block 808 is threadedly connected to the threaded rod 807 and its two sides are fully in contact with the first mounting groove 805, the moving block 808 will move in the first mounting groove 805 along the axial direction of the threaded rod 807. Because the moving block 808 is fixedly connected to the mounting plate 2, it will drive the mounting plate 2 and the paint pump 3, nozzle 4 and other components on the mounting plate 2 to move horizontally. The left and right adjustment of the spraying position is realized. At this time, the connecting block 901 is fixed on the side of the mounting plate 2 away from the moving block 808 and is slidably connected to the vertical rod 903 in the second mounting groove 902. When the mounting plate 2 moves under the action of the drive mechanism 8, the connecting block 901 slides along the vertical rod 903, providing stable support and guidance for the movement of the mounting plate 2, ensuring the smoothness of the movement of the mounting plate 2, and thus ensuring the stability of the nozzle 4 position during the spraying process. The material pipe 904 delivers paint to the paint pump 3, and the paint pump 3 sprays the paint through the nozzle 4 to spray paint the car parts. During the spraying operation, the sealing gasket 906 set between the nozzle 4 and the hollow baffle 7 can effectively prevent paint leakage, ensuring the normal progress of the spraying and the efficient use of paint.

[0028] Working principle: When using this device for painting automotive parts, the operator first places the automotive part to be painted on the placement platform 802, starts the first motor 801, and its transmission end drives the placement platform 802 to rotate, which can adjust the angle of the automotive part to facilitate painting operations on different parts. Next, if the painting position needs to be adjusted, the second motor 806 is started. The transmission end of the second motor 806 drives the threaded rod 807 to rotate. Because the moving block 808 is threadedly connected to the threaded rod 807 and its two sides are flush with the first mounting slot 805... When the mounting plate 2 is in place, the movable block 808 moves along the axial direction of the threaded rod 807 within the first mounting slot 805. Since the movable block 808 is fixedly connected to the mounting plate 2, it drives the mounting plate 2 and its components, such as the paint pump 3 and nozzle 4, to move horizontally, thus adjusting the spray position left and right. At this time, the connecting block 901 is fixed on the side of the mounting plate 2 away from the movable block 808 and is slidably connected to the vertical rod 903 in the second mounting slot 902. When the mounting plate 2 moves under the action of the drive mechanism 8, the connecting block 901 slides along the vertical rod 903. This provides stable support and guidance for the movement of the mounting plate 2, ensuring the smoothness of the movement process and thus guaranteeing the stability of the nozzle 4 position during painting. During painting, if the spray range needs to be changed, the adjusting motor 5 is activated. The transmission end of the adjusting motor 5 drives the cross-shaped adjusting frame 6 to rotate, causing the four hollow baffles 7 with different inner diameters on the outer side of the cross-shaped adjusting frame 6 to rotate accordingly. The operator can rotate the hollow baffle 7 with the appropriate inner diameter to the position corresponding to the nozzle 4 according to the actual painting needs, thereby controlling the paint spray range. For example, for... When painting delicate parts of automotive components, a hollow baffle 7 with a smaller inner diameter is used to limit the paint spray area and prevent paint from splashing onto surrounding areas that do not need to be painted. When painting large areas, the hollow baffle 7 with a larger inner diameter is switched to improve painting efficiency. The material pipe 904 delivers paint to the paint pump 3, which sprays the paint through the nozzle 4 to paint the automotive components. During the painting operation, the sealing gasket 906 between the nozzle 4 and the hollow baffle 7 can effectively prevent paint leakage, ensuring the normal progress of painting and the efficient use of paint.
