The housing 1 serves as the basic framework of the entire coating device, providing space for the installation and operation of various mechanisms within the device. A cleaning mechanism 5 is installed inside the housing 1. The cleaning mechanism 5 is mainly responsible for cleaning and coating the automotive bumper, and is a key part for pre-treatment before coating and the coating process. An inner support block 4 is fixedly connected to the inner wall of the housing 1, providing a rotation support point for the bidirectional screw in the adjustment mechanism 3. The adjustment mechanism 3 is installed inside the housing 1, and a conversion mechanism 7 is installed on the outer wall of the housing 1. The conversion mechanism 7 is used to control the switching of different functional components in the cleaning mechanism 5. The cleaning mechanism 5 includes a connecting block. 511, A connecting block 511 is slidably connected to the inner wall of the housing 1. The connecting block 511 can slide on the inner wall of the housing 1, allowing the cleaning mechanism 5 to be adjusted in position inside the housing 1. A housing 512 is fixedly connected to the outer wall of the connecting block 511. The housing 512 provides a relatively independent installation space for other components of the cleaning mechanism 5, serving to protect the internal components. A slider 513 is slidably connected to the outer wall of the housing 512. The sliding of the slider 513 can drive the connected components to move. A coating agent connecting pipe 514 is fixedly connected to the inner wall of the slider 513. The function of the coating agent connecting pipe 514 is to deliver the coating agent to the nozzle 5111, providing a source of coating agent for the coating operation of the bumper. An inner frame 515 is fixedly connected to the bottom. A motor B518 is fixedly connected to the outer wall of the inner frame 515. A screw is fixedly connected to the output end of the motor B518. The motor B518 serves as a power source, and the screw fixedly connected to its output end rotates under the drive of the motor B518. An internally threaded slider is threadedly connected to the outer wall of the screw. A brush block 519 is fixedly connected to the outer wall of the internally threaded slider. A nozzle 5111 is fixedly connected to the outer wall of the brush block 519. A coating agent supply pipe 516 is fixedly connected to the left side of the outer wall of the coating agent connecting pipe 514, providing coating agent to the coating agent connecting pipe 514. A water pipe 517 is fixedly connected to the left side of the outer wall of the brush block 519. Used to deliver cleaning agent and provide cleaning fluid for the cleaning operation of the bumper, the outer wall of the housing 512 is fixedly connected to the fixing frame 6. There are two fixing frames 6, which are symmetrically connected to the left and right ends of the housing 512 respectively. The fixing frame 6 is used to place the car bumper and ensure the stability of the bumper during the cleaning and coating process. The adjustment mechanism 3 includes a motor A and a double screw. The top of the housing 1 is fixedly connected to the motor A, and the output end of the motor A is fixedly connected to the double screw. The top end of the double screw is rotatably connected to the inner wall of the inner support block 4. The inner wall of the connecting block 511 is threaded to the outer wall of the double screw. The adjustment mechanism 3 realizes the fixing of bumpers of different specifications, so that the device can adapt to various types of car bumpers (for existing structures).

[0026] Reference Figure 1 , Figure 4 The conversion mechanism 7 includes an outer support plate 711, which is fixedly connected to the outer wall of the housing 1. The outer support plate 711 provides a mounting base for other components of the conversion mechanism 7, ensuring the stability of the conversion mechanism 7. A worm gear 712 is rotatably connected to the outer wall of the outer support plate 711. The worm gear 712 can rotate on the outer support plate 711, and the operation of the entire conversion mechanism 7 can be controlled by rotating the worm gear 712.

The outer wall of the worm gear 714 meshes with the outer wall of the worm 712. The coating agent supply pipe 516 and the water pipe 517 are both made of flexible material. The flexible material allows the coating agent supply pipe 516 and the water pipe 517 to bend and deform when the slider 513 moves and the conversion mechanism 7 moves, without affecting the delivery of coating agent and cleaning agent. A through groove is opened on the right side of the outer wall of the housing 1, and a drain hole 2 is opened at the bottom of the housing 1. The outer shell 512 is semi-open.

[0027] Working principle: A cleaning mechanism 5 is installed inside the housing 1. During use, the operator places the car bumper on the fixing frame 6 below. The motor A drives the bidirectional screw to rotate and fix the bumper of different specifications. By rotating the worm gear 712 on the outer wall of the housing 1, the worm gear 712 drives the worm wheel 714 to rotate, thereby controlling the switching between the inner frame 515 and the coating agent connecting pipe 514 inside the housing 512. When there are stains on both the top and bottom of the bumper, the motor B 518 drives the internal screw to rotate, thereby controlling the brush block 519 to move back and forth and work with the cleaning agent in the water pipe 517 to clean the bumper. During coating, the upper and lower sets of coating agent connecting pipes 514 are quickly switched to coat the top and bottom of the bumper simultaneously, speeding up the overall coating efficiency and eliminating the need to operate on the reverse side of the bumper. After the coating is completed, the operator removes the bumper.
