Description

Technical Field

[0001] This utility model relates to the field of weld repair coating, specifically an automated weld repair coating device with precise positioning. Background Technology

[0002] In existing barrel-making technology, the barrel body is formed by welding rectangular galvanized steel. Therefore, a vertical weld seam is inevitably produced during the welding process. As the production process progresses, it may also be necessary to weld lugs on both sides of the barrel body. These welding processes expose the inner and outer surfaces of the barrel body to high temperatures, causing damage to the surface galvanized layer and resulting in the loss of zinc layer protection. The weld seam lacks effective protection and is easily exposed to air for a long time, leading to rust and corrosion. To ensure the service life and appearance of the barrel body, the weld seam and lugs must be repaired and recoated in a timely manner.

[0003] Currently, this touch-up coating operation relies on manual labor. Manual touch-up is not only inefficient, but also results in incomplete and uneven coating, affecting the coating effect and increasing production costs. Since the inside of the barrel is mainly hollow, the barrel is prone to deformation under external pressure, which reduces the stability of the barrel or the protective effect. Therefore, it is necessary to design an automated weld seam touch-up coating equipment that can be precisely positioned to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automated weld repair coating device that can be precisely positioned to solve the problems mentioned in the background art.

[0025] Specifically, the recoating component includes two first cylinders 3 mounted on the top of the bracket 2 and near one side. A first push rod 4 extends from the bottom of each first cylinder 3. A mounting plate 5 is bolted to the bottom of the first push rod 4. A second cylinder 6 is bolted to the top of the mounting plate 5. A second push rod 7 extends from one end of the second cylinder 6. A feeding rack 8 is mounted to one end of the second push rod 7. A paint roller 9 is bolted to one end of the feeding rack 8. A guide plate 11 for mounting the identification module 10 is fixedly connected to the bottom of the feeding rack 8. The recoating component also includes a feeding box 12 fixedly mounted on the top of the bracket 2. An air guide pipe 13 is connected to the top of the feeding box 12. One end of the air guide pipe 13 is connected to an air pump 14. A guide pipe 15 is connected to the top of the feeding box 12. The other end of the guide pipe 15 is connected to the feeding rack 8. The paint roller 9 is rotatably connected to the feeding rack 8 by bolts. The guide plate 11 passes through the mounting plate 5 and is slidably connected to it.

[0026] The identification module 10 is mainly a color mark sensor, which can accurately identify the position of the weld and the support by recognizing the color mark on the barrel and transmit the information to the control system. The central control system includes the development of PLC and host computer control software. The control system is electrically connected to motor 18, first cylinder 3 and second cylinder 6. The control system realizes real-time monitoring and coordination of various functional modules and can switch between automatic or manual operation modes under different process requirements.

[0027] Furthermore, the first cylinder 3 can drive the mounting plate 5 to move up and down via the first push rod 4, and the second cylinder 6 can drive the paint roller 9 at one end of the feeding rack 8 to move laterally via the second push rod 7. The guide plate 11 can guide and limit the feeding rack 8 to prevent the paint roller 9 at one end of the feeding rack 8 from deviating, so that the paint roller 9 can adapt to the edge of the barrel with different diameters for painting operations. The air pump 14 can input gas into the feeding box 12 through the air guide pipe 13, so that the gas squeezes the paint liquid through the guide pipe 15 to supply the paint liquid to the feeding rack 8. While the paint roller 9 rotates, it picks up the paint liquid in the feeding rack 8 to perform a touch-up painting operation on the weld seam of the barrel.

[0028] More specifically, the driving component includes a rotating block 16 extending through the bottom of the base 1, a driven plate 17 fitted at the bottom of the rotating block 16, a motor 18 mounted at the bottom of the base 1 near the other side, a drive plate 19 fitted on the outside of the motor 18 via an output shaft, and the drive plate 19 and the driven plate 17 connected by a belt 20. The clamping component includes a fixed plate 21 fixedly connected to the top of the rotating block 16, an electric telescopic rod 22 fixedly connected to the edge of the fixed plate 21, a clamping plate 23 fixedly connected to one end of the electric telescopic rod 22, a guide block 28 fixedly connected to the bottom of the clamping plate 23, and the guide block 28 slidably connected to the fixed plate 21.

[0029] In addition, the motor 18 can drive the driven plate 17 to rotate via the belt 20 on the outside of the drive plate 19. The driven plate 17 can then drive the fixed plate 21 on the top of the rotating block 16 to rotate. The electric telescopic rod 22 can drive the clamping plate 23 to clamp and fix barrels of different diameters. The fixed plate 21 can rotate the fixed workpiece. The guide block 28 slides within the fixed plate 21 and guides and limits the clamping plate 23 to prevent it from shifting.

[0030] Furthermore, the pressing component includes a third cylinder 24 mounted on the top of the bracket 2, a third push rod 25 extending from one end of the second cylinder 6, a fixing block 26 fixedly connected to the bottom of the third push rod 25, a driven plate 27 fitted on the outside of the fixing block 26, and the fixing block 26 and the driven plate 27 being rotatably connected.

The driven plate 27 presses down and fixes the top of the workpiece. When the fixed plate 21 drives the workpiece to rotate, the workpiece drives the driven plate 27 to rotate outside the fixed block 26.

[0032] Working principle: First, the workpiece is placed on the fixed plate 21. Then, the third cylinder 24 is started, which drives the driven plate 27 at the bottom of the fixed block 26 to move downward through the third push rod 25. Then, the driven plate 27 presses down and fixes the top of the workpiece. Then, the first cylinder 3 and the second cylinder 6 are started, which drives the mounting plate 5 to move up and down through the first push rod 4. The surface of the barrel is identified by the identification module 10. At the same time, the motor 18 is started, which drives the driven plate 17 to rotate through the belt 20 on the outside of the drive plate 19. The driven plate 17 drives the fixed plate 21 at the top of the rotating block 16 to rotate. At the same time, the fixed plate 21 drives the workpiece to rotate.

[0033] When the identification module 10 identifies the position to be coated, the second cylinder 6 drives the paint roller 9 at one end of the feed rack 8 to move laterally through the second push rod 7. Then the paint roller 9 contacts the edge of the barrel to perform the coating operation. At the same time, the air pump 14 is started, so that it inputs gas into the feed box 12 through the air guide pipe 13, so that the gas squeezes the paint liquid through the guide pipe 15 to supply the paint liquid to the feed rack 8.
