Technical Field
[0001] This utility model relates to the field of automotive parts processing, and in particular to a rotating device for injection-molded spray-painted workpieces of the lower trim strip of the front grille. Background Technology
[0002] As the visual focal point of a car's front end, the front grille is like the facial features of a person. Its design and craftsmanship largely determine the overall temperament and style of the car. The lower trim strip of the front grille, as an important component of the front grille, not only serves a decorative purpose but also optimizes the smoothness of the front lines and improves the vehicle's aerodynamic performance. The importance of its appearance quality is self-evident.
[0003] In the existing process of spraying the lower trim strip of the front grille, the workpiece is usually fixed in a specific position, and the spray gun sprays the workpiece with a preset trajectory and angle. However, due to the irregularity of the irregular surface of the lower trim strip of the front grille, the paint is easily unevenly distributed due to changes in spraying distance and angle, resulting in local coatings that are too thick or too thin.
[0004] Therefore, it is necessary to design a rotating device for injection-molded and sprayed front grille lower trim strips that can rotate and adjust its height according to the irregular shape of the front grille lower trim strip, ensuring uniform coating coverage and improving product quality. Utility Model Content

[0006] The technical solution is as follows: A rotating device for injection-molded and sprayed workpieces of the lower trim strip of the front grille includes a protective box, a sealing door, a first motor, a one-way screw, a first slider, a first electric push rod, a spray frame, a storage box, a conveying hose, and an adjustment component. The sealing door is rotatably connected to the front left of the protective box, and the first motor is connected to the upper right of the protective box. A one-way screw is connected to the output shaft of the first motor and is rotatably connected to the protective box. The first slider is threadedly connected to the one-way screw and is slidably connected to the upper part of the protective box. The first electric push rod is connected to the lower side of the first slider, and the spray frame is connected to the telescopic end of the first electric push rod. The storage box is connected to the upper side of the protective box, and a conveying hose is connected between the storage box and the spray frame. The lower part of the protective box is provided with an adjustment component that can rotate and adjust the height according to the irregular surface of the lower trim strip of the front grille.

[0008] Preferably, it also includes an exhaust pipe, which is connected to the upper left side of the protective box.
[0009] Preferably, it also includes a flat belt and a mixing frame. The mixing frame is rotatably connected to the middle of the storage box. Both the one-way screw and the right side of the mixing frame are equipped with pulleys, and a flat belt is wound between the pulleys.
[0010] Preferably, the adjustment assembly includes a bidirectional lead screw, a second slider, a second electric actuator, a first connecting frame, a second connecting frame, a suction cup, a torsion spring, a second motor, and a rotating shaft. The bidirectional lead screw is rotatably connected to the lower part of the protective box. The left and right sides of the bidirectional lead screw are slidably connected to the second sliders, which are slidably connected to the protective box. The upper part of each second slider is rotatably connected to the first connecting frame. The upper side of each first connecting frame is connected to the second electric actuator.

A first slider 6 is threadedly connected to the one-way screw 5. The first slider 6 is slidably connected to the upper part of the protective box 1. A first electric push rod 7 is connected to the lower side of the first slider 6. A spray frame 8 is connected to the telescopic end of the first electric push rod 7. A storage box 9 is connected to the upper side of the protective box 1. A mixing frame 11 is rotatably connected to the middle of the storage box 9. Both the one-way screw 5 and the mixing frame 11 are equipped with pulleys on the right side. A flat belt 10 is wound between the pulleys. A conveying hose 12 is connected between the storage box 9 and the spray frame 8. An adjustment component is provided at the lower part of the protective box 1.
[0022] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the adjustment assembly includes a bidirectional lead screw 13, a second slider 14, a second electric actuator 15, a first connecting frame 16, a second connecting frame 17, a suction cup 18, a torsion spring 19, a second motor 20, and a rotating shaft 21. The lower part of the protective box 1 is rotatably connected to the bidirectional lead screw 13. A rotating handle is provided on the right side of the bidirectional lead screw 13 for easy rotation. The left and right sides of the bidirectional lead screw 13 are slidably connected to the second slider 14. The second slider 14 is slidably connected to the protective box 1. The upper part of the second slider 14... Each of the first connecting frames 16 is rotatably connected to a first connecting frame 16. Each of the first connecting frames 16 is connected to a second electric push rod 15. Each of the second electric push rod 15 is connected to a second connecting frame 17 at its telescopic end. Each of the second connecting frames 17 is rotatably connected to a suction cup 18. Each suction cup 18 is connected to an adjacent second connecting frame 17 by a torsion spring 19. A second motor 20 is connected to the lower right side of the protective box 1. A rotating shaft 21 is connected to the output shaft of the second motor 20. Each of the first connecting frames 16 is slidably connected to the rotating shaft 21.
[0023] When using this device, first place the protective box 1 in the spraying area of the lower trim strip of the front grille, then rotate the double-acting screw 13 to move the second slider 14 under the action of the thread, driving the first connecting frame 16 to move on the rotating shaft 21. Adjust according to the length of the lower trim strip of the front grille. Then place the lower trim strip of the front grille between the upper sides of the suction cup 18, and use the suction cup 18 to adsorb and fix the lower trim strip of the front grille. Then rotate and close the sealing door 2, and then put the paint into the storage box 9. Then start the first electric push rod 7 to move the spray frame 8 downward and adjust the height of the spray frame 8. Then start the first motor 4 to drive the one-way screw 5 to rotate, causing the first slider 6 to move under the action of the thread, so that the paint in the storage box 9 is sprayed out from the spray frame 8 through the delivery hose 12, and the harmful gases generated during spraying are discharged from the exhaust pipe 3. At the same time, the rotation of the one-way screw 5 will drive the pulley to rotate, causing the flat belt 10 to rotate, driving the mixing frame 11 to rotate, and the mixing frame 11 to stir the paint in the storage box 9. This allows for stirring of the paint in the storage tank 9 during the spraying process, preventing pigment sedimentation and solvent separation, and ensuring uniform distribution of paint components. When it is necessary to spray the irregularly shaped surface of the lower trim strip of the front grille, the second electric actuator 15 on the end of the surface to be sprayed can be activated, driving the second connecting frame 17 to move upward, causing the suction cup 18 to rotate, and the torsion spring 19 to deform, causing the lower trim strip of the front grille to tilt, so that the irregularly shaped surface of the lower trim strip of the front grille faces the spray frame 8, and the paint is sprayed through the spray frame 8. When it is necessary to spray the inclined side surface of the lower trim strip of the front grille, the second motor 20 can be started to drive the rotating shaft 21 to rotate, so that the second electric push rod 15 rotates back and forth, driving the lower trim strip of the front grille to rotate, so that the surface of the lower trim strip of the front grille to be sprayed faces the spraying frame 8. This allows for rotation and height adjustment according to the irregular shape of the lower trim strip of the front grille, ensuring uniform coating coverage and improving product quality. After spraying is completed, the lower trim strip of the front grille is removed, the torsion spring 19 returns to its original position, and the suction cup 18 rotates to reset.
