Description

Technical Field

[0001] This utility model relates to the field of spray painting equipment technology, and in particular to a plate positioning spray painting device. Background Technology

[0002] In the industrial production field, spray painting equipment is a key piece of equipment for surface treatment of various types of boards. Its function is to uniformly spray paint onto the surface of the boards to protect them and improve their appearance. Traditional spray painting operations are mostly done manually, which is not only inefficient, but also the quality of the paint is greatly affected by the operator's skill and experience, making it difficult to guarantee the uniformity and consistency of the coating. With the development of technology, automated spray painting equipment has emerged. These devices realize the automation of the spray painting process through mechanical structure and control system, improving production efficiency and paint quality. A common spray painting equipment consists of a paint supply system, a paint gun, a motion mechanism, and a control system. The paint supply system is responsible for delivering paint to the paint gun, the motion mechanism drives the paint gun to move along a preset trajectory, and the control system precisely controls the entire spray painting process.

[0003] However, traditional spray painting equipment often lacks effective solutions for the positioning of sheet materials, leading to easy displacement of the sheet materials during the painting process and affecting the painting effect. Although existing spray painting equipment has solved the problems of low efficiency and unstable quality of manual spray painting to some extent, it still has some shortcomings. Existing equipment uses simple clamps or fixed supports for sheet material positioning. During the painting process, the sheet material is affected by the pressure of the spray gun, the impact of the paint, and the vibration of the equipment itself. These clamps and fixed supports cannot guarantee the absolute stability of the sheet material. When painting larger sheet materials, the edges of the sheet material are prone to slight displacement, causing deviations in the painting at these parts and affecting the overall painting effect. Therefore, we propose a sheet material positioning spray painting device. Utility Model Content

A paint supply pump 17 is fixedly connected to the front end of the right square frame 3, providing paint for the spraying operation. Vertical rods 4 are fixedly connected to the top of the front and rear ends of the two square frames 3. The vertical rods 4 support horizontal rods 5 to form a frame structure. The top of the multiple vertical rods 4 is fixedly connected to corresponding horizontal rods 5. The horizontal rods 5 have grooves on adjacent sides to provide sliding tracks for sliding beams 6. Sliding beams 6 are slidably connected to adjacent sides of the two horizontal rods 5. The sliding beams 6 can slide along the horizontal rods 5. The painting position is adjusted by translation. Workpiece plates 7 are fixedly connected to the bottom of adjacent sides of the two sliding beams 6. Workpiece plates 7 support motors 8 and related transmission components. Motor 8 is fixedly connected to the top of workpiece plates 7, providing rotational power to rotating rod 19. The output end of motor 8 passes through workpiece plates 7 and is fixedly connected to rotating rod 19. Rotating rod 19 transmits the rotational motion of motor 8 to rotating rod 20. Rotating rod 20 is rotatably connected to the rear bottom of rotating rod 19. Rotating rod 20 changes direction of motion through sliding contact with rocker arm 11. Rocker arm 11 is rotatably connected to the bottom left side of workpiece plates 7. Rod 11 converts the rotational motion of rotating rod 10 into the oscillating motion of nozzle 15. The outer wall of rotating rod 10 is slidably connected to the inner side of rocker arm 11.

The limiting groove 16 is fixed at the bottom of the workpiece plate 7 to limit the movement trajectory of the round rod 13. The bottom end of the round rod 13 is connected to the nozzle 15 through the universal joint 14 to realize multi-angle rotation and swing. The plate positioning mechanism 2 is fixed to the workpiece plate 7. At the bottom of the worktable 1, the spatial coordinates of the board are locked by a mechanical positioning structure. This device realizes multi-dimensional dynamic painting control. By combining the horizontal movement of the sliding beam 6 with the angle adjustment of the nozzle 15, it can adapt to the all-round painting needs of boards of different sizes. The board positioning mechanism 2 adopts a physical limit structure to ensure that the board does not shift during processing. With the precise drive of the motor 8, the painting accuracy and uniformity are significantly improved. The sliding cooperation between the limit groove 16 and the round rod 13 effectively reduces motion error. The design of the universal head 14 allows the nozzle 15 to flexibly adjust the spraying angle, avoiding the coverage blind spot problem of the traditional fixed nozzle 15, and enhancing the convenience of maintenance. Each transmission component adopts a low-friction connection method, which reduces mechanical wear and extends the service life of the equipment.

[0035] Specifically, the air pump 209 is fixed to the bottom left side of the panel 201 and drives the rear transmission rod 204 to move horizontally. The transmission rod 204 drives the positioning feet 208 to move vertically through the connector 207. At the same time, the transmission rod 204 drives the transmission rod 205 to rotate through the transmission rod 206. The transmission rod 205 drives the front transmission rod 206 and the transmission rod 204 to move synchronously, realizing the synchronous adjustment of the four positioning feet 208. The panel 201 maintains stable movement through the sliding connection between the slider 202 and the slide rail 203. The rotational connection between the transmission rod 204 and the transmission rod 206 converts the horizontal movement into vertical movement. The connector 207 passes through the worktable 1 to realize the vertical movement of the positioning feet 208. The lifting and lowering mechanism utilizes the horizontal movement of the transmission rod 204 driven by the air pump 209 and the vertical conversion of the connecting piece 207 to quickly adjust the height of the positioning feet 208 to accommodate plates of different thicknesses. The linkage structure of the transmission rods 205 and 206 ensures that the four positioning feet 208 move synchronously, preventing deformation caused by uneven force on the plate. The cooperation between the slider 202 and the slide rail 203 ensures smooth movement of the panel 201. The mechanical limit structure keeps the plate without displacement during dynamic processing. The modular design makes maintenance more convenient. The air pump 209 provides a stable power source.

[0040] Working Principle: In operation, a panel positioning and spraying device uses a worktable 1 supported by a square frame 3 fixed at the bottom. A paint pump 17 at the front end of the right square frame 3 supplies paint. The tops of the two square frames 3 are fixed to a horizontal bar 5 via vertical rods 4, forming a gantry frame. A sliding beam 6 slides horizontally along the horizontal bar 5, moving the workpiece plate 7 fixed at the bottom to adjust the spraying position. A motor 8 at the top of the workpiece plate 7 drives a rotating rod 9 to rotate. A rotating rod 10 at the bottom of the rotating rod 9 drives a rocker arm 11 to swing via a sliding connection. The right end of the rocker arm 11 drives a round rod 13 to slide within a limiting groove 16 via a fixed groove 12. A universal joint 14 at the bottom of the round rod 13 drives a nozzle 15 to achieve three-dimensional angle adjustment. The paint pump 17 then... Paint is delivered to nozzle 15. Motor 8, through the transmission of rotating rod 1 9 and rotating rod 2 10, causes rocker arm 11 to drive round rod 13 to reciprocate within limiting groove 16. Round rod 13 drives nozzle 15 to swing at multiple angles through universal head 14. Combined with the horizontal movement of sliding beam 6 along crossbar 5, full coverage spraying of the board surface is achieved. Limiting groove 16 restricts the movement trajectory of round rod 13 to ensure the swing angle and position accuracy of nozzle 15. Universal head 14 allows nozzle 15 to rotate freely in the vertical plane to adapt to the painting needs of complex curved surfaces. Through the synergistic effect of mechanical transmission and positioning mechanism, precise positioning and dynamic painting of the board are achieved, ensuring coating uniformity and processing efficiency.

[0041] Furthermore, when the plate positioning mechanism 2 is working, the top of the panel 201 is fixed to the bottom of the workbench 1, and the sliders 202 on the front, rear, left and right sides of the bottom of the panel 201 slide on the slide rail 203. The bottom of the slide rail 203 is fixedly connected to the first transmission rod 204. The bottom of the panel 201 is rotatably connected to the second transmission rod 205. The front and rear sides of the bottom of the second transmission rod 205 are respectively rotatably connected to the third transmission rod 206. The top of the opposite end of the third transmission rod 206 is rotatably connected to the bottom of the corresponding first transmission rod 204. The top left and right sides of the first transmission rod 204 are rotatably connected to the connecting piece 207. The top of the connecting piece 207 passes through the workbench 1 and is rotatably connected to the positioning foot 208. The output end of the air pump 209 on the bottom left of the panel 201 is fixedly connected to the bottom left of the rear transmission rod 204. At the end, after the air pump 209 is started, it pushes the rear transmission rod 1 204 to move horizontally. The rear transmission rod 1 204 drives the transmission rod 205 to rotate through the transmission rod 3 206. The rotation of the transmission rod 205, in turn, drives the front transmission rod 1 204 to move synchronously through the front transmission rod 3 206. The transmission rod 1 204 drives the positioning foot 208 to rise and fall vertically through the connector 207, thereby locking the spatial coordinates of the board. The slider 202 and the slide rail 203 cooperate to ensure the stability of the horizontal movement of the transmission rod 1 204. The connector 207 converts the horizontal movement of the transmission rod 1 204 into the vertical movement of the positioning foot 208. The air pump 209 provides power to make the entire positioning mechanism move, thereby achieving precise positioning of the board and ensuring that the board does not shift during dynamic processing.
