Description

Technical Field

[0001] This application relates to the field of automotive technology, and more particularly to an automatic spraying device for automotive exterior parts. Background Technology

[0002] Automotive exterior parts mainly include front and rear bumpers, grilles, rearview mirrors, side skirts, headlights, wheel arches, pillar trim, roof racks, door handles, sunroofs, and windshield wipers. These parts are connected to the car body by bolts or clips, combining aesthetics and functionality. The coating of automotive exterior parts can effectively isolate corrosive media such as moisture, oxygen, and industrial exhaust gases, delaying the process of damage to the car and extending its service life.

[0003] Currently, automated painting of automotive exterior parts uses spray nozzles to comprehensively paint the exterior parts of the production line. However, there are gaps between the sheet metal parts. The current method is to manually touch up the paint. The paint materials pose certain chemical hazards to the production workers. In addition, manual painting is inefficient, slows down the production cycle, and results in inconsistent paint thickness and unstable product quality. Utility Model Content

[0004] This application provides an automatic painting device for automotive exterior parts to solve the problems of manual repainting, where the sprayed materials pose certain chemical hazards to the production personnel, and where manual painting is inefficient, slows down the production cycle, and results in inconsistent paint thickness and unstable product quality.

[0005] This application provides an automatic painting device for automotive exterior parts, including a painting mechanism. The painting mechanism has a fixed transverse slide plate, a servo motor three fixedly connected to the transverse slide plate, and a PLC control circuit connected to the servo motor three. The transverse slide plate is movably connected to a transverse lead screw and linear guide assembly, a servo motor one fixedly connected to the transverse lead screw and linear guide assembly, a PLC control circuit connected to the servo motor one. A crossbeam is fixed to the transverse lead screw and linear guide assembly, a longitudinal lead screw and linear guide assembly is movably connected to the crossbeam, a servo motor two fixedly connected to the longitudinal lead screw and linear guide assembly, a PLC control circuit connected to the longitudinal lead screw and linear guide assembly, and a column fixedly connected to the longitudinal lead screw and linear guide assembly. A ground chain moves linearly below the painting mechanism.

[0006] Preferably, the servo motor is fixedly connected to a pulley, the pulley is synchronously connected to a second pulley, and the second pulley is fixedly connected to a spraying mechanism.

[0007] Preferably, the column is fixedly connected to a tank chain one, and the crossbeam is fixedly connected to a tank chain two.

[0008] Preferably, the transverse lead screw and linear guide transmission assembly is fixedly connected to a buffer block one, and the longitudinal lead screw and linear guide transmission assembly is fixedly connected to a buffer block two.

[0009] Preferably, the column is fixedly connected with an angle iron.

[0010] Preferably, the horizontal sliding plate is fixedly connected to a reinforcing plate.

[0011] Preferably, the pulley is equipped with a position sensor. Beneficial Effects: The spraying mechanism is mounted on a horizontal slide plate. Servo motor three controls the rotation of the spraying mechanism, allowing it to spray at any angle with high precision. Servo motor one controls the horizontal lead screw and linear guide group, enabling precise horizontal linear motion of the slide plate. Servo motor two controls the longitudinal lead screw and linear guide group, enabling precise longitudinal linear motion of the crossbeam. A ground chain below the spraying mechanism allows for the gradual transport of automotive exterior parts according to the production rhythm. A PLC control circuit controls the servo motors for automatic spraying. Multi-axis linkage spraying allows for targeted spraying of sheet metal gaps with high positioning accuracy, avoiding chemical hazards to production personnel from the sprayed materials. It increases spraying efficiency, accelerates production cycle, and produces uniform paint thickness and stable product quality. Servo motor three is connected to pulley one, which in turn is connected to pulley two. Pulley two houses the spraying mechanism, allowing for the use of a smaller servo motor to provide greater torque and reducing manufacturing costs. A tank chain is installed on the column, and a tank chain two is fixed to the crossbeam, providing excellent protection for the pipeline wiring during spraying operation. By incorporating a buffer block one in the transverse lead screw and linear guide transmission assembly and a buffer block two in the longitudinal lead screw and linear guide transmission assembly, the dangerous situation of overtravel of the crossbeam and transverse slide plate in the event of machine malfunction is prevented. Angle irons are installed on the columns, increasing their rigidity. Ribs are also installed on the transverse slide plate, further enhancing the rigidity of the columns. Position sensors are integrated into the pulleys, allowing for more precise control of the spraying mechanism's rotation angle.
