[0002] A painting robot is an industrial robot used for automatically spraying paint or other coatings. Its core component is the spraying mechanism, which typically includes a spraying device, a control system, and a distance measuring device. The spraying device is responsible for evenly spraying the coating onto the workpiece surface.
[0003] A search of Chinese patent CN218251052U reveals a spraying robot spraying mechanism, comprising a base and a support plate fixedly connected to the top of the base. A guide rod and a first drive motor are fixedly connected to the top of the support plate. A first lead screw is fixedly connected to the top output end of the first drive motor. A mounting bracket is slidably connected to the guide rod, and the mounting bracket is threadedly connected to the first lead screw. Symmetrically fixed lead screw supports are fixed to the top of the mounting bracket. A second lead screw is rotatably connected between the lead screw supports. A second drive motor is fixedly connected to the outer side of the lead screw support near the first lead screw, and the output end of the second drive motor is fixedly connected to the second lead screw. A guide groove is formed in the middle of the mounting bracket, and a spraying component is slidably connected to the guide groove. The spraying component is threadedly connected to the second lead screw. The overall mechanism has the advantages of high spraying efficiency and convenient cleaning and maintenance, making it convenient and practical.
[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. Excess paint generated during the spraying process accumulates on the spraying robot, which is not easy to clean. Over time, the excess paint will affect the operation of the spraying robot. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a spraying mechanism for a spraying robot.
[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0007] An embodiment of this utility model provides a spraying mechanism for a spraying robot, including a bracket, a spray pipe fixedly mounted on the bracket, an interface and a nozzle fixedly mounted at both ends of the spray pipe, a collection mechanism on the bracket, a scraping mechanism on the collection mechanism, and a vibration mechanism shared between the collection mechanism and the scraping mechanism.
[0008] The collection mechanism includes a connecting plate fixedly mounted on the bracket, and a collection shell is fixedly mounted on the connecting plate;
[0009] The scraping mechanism includes a support ring fixedly installed on the collection shell, a drive assembly is provided between the connecting plate and the support ring, and a scraper is provided on the drive assembly that is rotatably connected to the collection shell;
[0010] The vibration mechanism includes a support assembly disposed on the collection shell, a connecting frame disposed on the support assembly, a movable ring fixedly mounted on the connecting frame, and an actuating component disposed between the support assembly and the scraper.
[0011] Furthermore, the drive assembly includes a toothed ring rotatably mounted inside the support ring.
[0012] Furthermore, the drive assembly also includes a drive motor disposed on the connecting plate, and a gear that meshes with the gear ring is fixedly mounted on the output end of the drive motor.
[0013] Furthermore, a card holder is fixedly installed on the bracket, and a bottom shell is snapped onto the card holder.
[0014] Furthermore, the support assembly includes a fixed shell that is fixedly installed on the collection shell, a spring connected to the inner wall of the fixed shell, and a telescopic block that is slidably connected to the end of the spring and the telescopic block being fixed to the connecting frame.
[0015] Furthermore, the actuation component includes a fixing block fixedly mounted on the telescopic block.
[0016] Furthermore, the triggering component also includes a base frame fixedly mounted on the end of the scraper, on which an extrusion block adapted to the fixing block is fixedly mounted.
[0017] The above-described solution of this utility model has at least the following beneficial effects:
[0018] 1. In this utility model, the excess paint generated during spraying is collected by the collection shell, and the drive motor is controlled to operate. The scraper can scrape the solidified paint on the collection shell, so that the paint falls through the collection shell to the inside of the bottom shell, thereby facilitating the collection and cleaning of the paint.
[0019] 2. In this utility model, when the scraper is in motion, it drives the extrusion block to move through the base frame, causing the extrusion block to press against the fixed block. The fixed block then drives the movable ring downward through the telescopic block and the connecting frame. When the extrusion block separates from the fixed block, the spring can use its own elastic force to drive the movable ring upward through the telescopic block and the connecting frame to reset, causing the movable ring to strike the collection shell and generate vibration. This improves the efficiency of separating the paint from the collection shell, making it easier for the paint to fall into the inner side of the bottom shell and facilitating collection.

[0027] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0028] like Figures 1 to 5 As shown, an embodiment of this utility model provides a spraying mechanism for a spraying robot, including a bracket 1, a spray pipe 2 fixedly installed on the bracket 1, an interface 3 and a nozzle 4 fixedly installed at both ends of the spray pipe 2, and a collection mechanism provided on the bracket 1, the collection mechanism including a connecting plate 5 fixedly installed on the bracket 1, and a collection shell 6 fixedly installed on the connecting plate 5.
[0029] In this embodiment of the utility model, interface 3 is connected to an external coating conveying device. The operator moves the workpiece between the nozzle 4 and the collection shell 6 using a handling device, and controls the external coating conveying device to operate, so that the coating moves to the inside of the nozzle 4 through interface 3 and nozzle 2, and is sprayed out by the nozzle 4 to spray the workpiece. The excess coating produced during spraying is sprayed onto the inside of the collection shell 6.
[0030] Figures 1 to 5 As shown, the collection mechanism is equipped with a scraping mechanism, which includes a support ring 7 fixedly installed on the collection shell 6. A drive assembly is provided between the connecting plate 5 and the support ring 7. The drive assembly is equipped with a scraper 11 that is rotatably connected to the collection shell 6. The drive assembly includes a toothed ring 8 rotatably installed inside the support ring 7. The drive assembly also includes a drive motor 9 fixedly installed on the connecting plate 5. A gear 10 that meshes with the toothed ring 8 is fixedly installed on the output end of the drive motor 9. A bracket 12 is fixedly installed on the bracket 1, and a bottom shell 13 is clamped on the bracket 12.
[0031] In this embodiment of the utility model, the worker collects the excess paint generated during spraying through the collection shell 6. By controlling the drive motor 9 to operate, the output end of the drive motor 9 rotates, which drives the gear 10 to rotate. The gear 10 meshes with the gear ring 8 to rotate, which in turn drives the scraper 11 to rotate. The scraper 11 scrapes the solidified paint on the collection shell 6, causing the paint to fall through the collection shell 6 to the inside of the bottom shell 13, thus facilitating the collection and cleaning of the paint.
[0032] The staff regularly removes the bottom shell 13, treats the paint collected inside the bottom shell 13, and then reattaches the treated bottom shell 13 to the bracket 12.
[0033] Figures 1 to 5 As shown, a vibration mechanism is provided between the collection mechanism and the scraping mechanism. The vibration mechanism includes a support assembly on the collection shell 6, a connecting frame 17 on the support assembly, and a movable ring 18 fixedly installed on the connecting frame 17. An actuation assembly is provided between the support assembly and the scraper 11. The support assembly includes a fixed shell 14 fixedly installed on the collection shell 6. A spring 15 is connected to the inner wall of the fixed shell 14. A telescopic block 16 that is slidably connected to the fixed shell 14 is connected to the end of the spring 15. The telescopic block 16 is fixed to the connecting frame 17. The actuation assembly includes a fixed block 19 fixedly installed on the telescopic block 16. The actuation assembly also includes a base frame 20 fixedly installed at the end of the scraper 11. An extrusion block 21 that is adapted to the fixed block 19 is fixedly installed on the base frame 20.
[0034] In this embodiment of the utility model, when the scraper 11 is in motion, it drives the squeezing block 21 to move through the base frame 20, so that the squeezing block 21 squeezes the fixed block 19, and the fixed block 19 drives the movable ring 18 to move downward through the telescopic block 16 and the connecting frame 17. When the squeezing block 21 separates from the fixed block 19, the spring 15 can use its own elastic force to drive the movable ring 18 to move upward through the telescopic block 16 and the connecting frame 17 to reset, so that the movable ring 18 strikes the collection shell 6 to generate vibration, thereby improving the efficiency of the paint separating from the collection shell 6, making it easier for the paint to fall into the inner side of the bottom shell 13, and facilitating the collection work.
[0035] Working principle: The operator moves the workpiece between the nozzle 4 and the collection shell 6 using a handling device, and controls the operation of the external paint conveying equipment to move the paint through the interface 3 and the spray pipe 2 to the inside of the nozzle 4. The paint is then sprayed from the nozzle 4 to coat the workpiece. Excess paint is sprayed onto the inside of the collection shell 6, which collects the excess paint. The drive motor 9 is controlled to operate, and the scraper 11 scrapes the solidified paint on the collection shell 6, allowing the paint to pass through the collection shell 6. When the coating falls into the inner side of the bottom shell 13, the scraper 11 moves through the base frame 20 to drive the extrusion block 21 to move, causing the extrusion block 21 to press the fixed block 19. The fixed block 19 then moves the movable ring 18 downward through the telescopic block 16 and the connecting frame 17. When the extrusion block 21 separates from the fixed block 19, the spring 15 can use its own elastic force to move the movable ring 18 upward through the telescopic block 16 and the connecting frame 17 to reset. This causes the movable ring 18 to strike the collection shell 6 and vibrate, causing the coating to fall into the inner side of the bottom shell 13.
[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
