Description

Technical Field

[0001] This invention relates to the field of robot parts processing technology, and more particularly to a barrel plating apparatus for processing robot parts. Background Technology

[0002] Existing robot parts processing spraying machines typically involve placing the robot parts into a spraying cylinder with numerous perforations on its sidewalls, then immersing them in a spraying tank for spraying. Since the spraying cylinder is generally quite long, the inlet and outlet ports are usually located on the sidewalls at both ends of the cylinder for easy unloading and collection after spraying. However, the size of the inlet and outlet ports is limited by the support shaft located at the central axis of the cylinder, which needs to be avoided. This affects the loading and unloading speeds. Furthermore, because the position of the inlet and outlet ports changes with the rotation of the spraying cylinder, the cylinder must be rotated to adjust their positions during loading and unloading. Additionally, there are issues with slow solution circulation on the inner sidewalls and difficulty in replenishing the cations consumed within the spraying cylinder. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as: In the use of existing robot parts processing spraying machines, robot parts are usually placed into a spraying cylinder with many sieve holes on the side wall, and then immersed in a spraying tank for spraying. Since the spraying cylinder is generally long, in order to facilitate unloading and collection after spraying, the inlet and outlet are usually set on the side walls at both ends of the spraying cylinder. Due to the influence of the support shaft located at the central axis of the spraying cylinder, which provides support for the spraying cylinder, the size of the inlet and outlet is limited because it needs to avoid the support shaft, which in turn affects the loading and unloading speed. Moreover, since the position of the inlet and outlet changes with the rotation of the spraying cylinder, the spraying cylinder needs to be rotated to adjust the position of the inlet and outlet during loading and unloading. In addition, there is also the problem of slow solution circulation on the inner side wall, and the difficulty in replenishing the cations consumed in the spraying cylinder.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A barrel plating device for processing robot parts includes a support frame and a spray tank. A spraying assembly is rotatably connected to one side wall of the support frame. The spraying assembly includes two mounting seats, and a support shaft is fixedly connected between the two mounting seats. Two baffles are symmetrically fixedly connected to the support shaft. An external gear ring is rotatably connected to each of the two baffles. A spraying cylinder is fixedly connected between the two external gear rings. The baffles and the spraying cylinder are rotatably connected. A reinforcing ring is fixedly connected between the spraying cylinder and the external gear rings. The baffles have grooves, and inlet / outlet gates are rotatably connected within the grooves. The baffles and the inlet / outlet gates are rotatably connected via hinges. A magnetic block is fixedly connected to the side wall of the inlet / outlet gate near the mounting seat. The baffles are equipped with a limit adjustment device. A loading / unloading rotation adjustment device is provided between one end of the support frame and the mounting seat. A spraying drive device is provided inside the support frame, and a material replenishment device is provided inside the spray tank.

[0005] Preferably, the limiting adjustment device includes a rotating rod, which is rotatably connected to one side wall of the baffle. A stop rod is fixedly connected inside the rotating rod, and an adjusting rod is fixedly connected to one side wall of the stop rod.

[0006] Preferably, the loading and unloading rotation adjustment device includes two side plates, both of which are fixedly connected to one side wall of the bracket. A winding roller is rotatably connected between the two side plates. A connecting rope is wound on the winding roller. One end of the connecting rope is fixedly connected to one of the mounting seats. A second drive motor is fixedly connected to one side wall of one of the side plates. The output end of the second drive motor passes through the side plate and is fixedly connected to the winding roller.

[0007] Preferably, the spraying drive device includes a first drive motor, and a drive shaft that passes through the bracket is fixedly connected to the output end of the first drive motor. Two first gears are symmetrically fixedly connected to the drive shaft. The two first gears are arranged in a one-to-one correspondence with two external gear rings. The outer side wall of the external gear ring is provided with teeth that mesh with the first gears.

[0008] Preferably, the material replenishment device includes a base plate, which is fixedly connected to the inner wall of the spray tank. Multiple adapters are rotatably connected inside the base plate, and a drive shaft is fixedly connected to each adapter. A fan blade is fixedly connected to one end of each drive shaft. Two connectors are symmetrically fixedly connected to the inner wall of the spray tank, and a worm gear is rotatably connected between the two connectors. A second gear meshing with the worm gear is fixedly connected to the drive shaft. Two worm wheels are symmetrically fixedly connected to the worm gear, and the two worm wheels are arranged in a one-to-one correspondence with two external gear rings, with the worm wheels meshing with the external gear rings.

[0009] Preferably, multiple fixing plates are symmetrically fixedly connected to the outer side wall of the support shaft, and a guide plate is fixedly connected to the end of each fixing plate away from the support shaft. The side wall of the guide plate away from the support shaft is arc-shaped.

[0010] Preferably, a support plate is fixedly connected to one side wall of the bracket, and two rotating shafts are symmetrically fixedly connected to the outer side wall of the support plate. Each of the two rotating shafts is rotatably connected to a mounting plate, and both mounting plates are fixedly connected to one side wall of the mounting base.

[0011] The beneficial effects of this invention are: Compared to the traditional side-loading method, there is no need to rotate the spray cylinder to adjust the position of the inlet and outlet gates, making it simpler and more convenient to use. At the same time, because the connection between the support shaft and the baffle is not located in the center of the baffle, the inlet and outlet gates can be set larger, making loading and unloading easier. Furthermore, because the position of the support shaft is higher than the central axis of the spray cylinder, the parts inside the spray cylinder are less likely to be blocked by the support shaft during the spraying and tumbling process, thus causing less interference to the spraying process of the parts inside the spray cylinder. This allows more parts to be placed inside, and more parts to be processed at once.

[0012] By accelerating the flow between the solution inside and outside the spray gun, the replenishment of cations in the solution inside the spray gun is accelerated during the spraying process. Inside the spray gun, the solution flows from top to bottom, which can accelerate the falling speed of the parts during the tumbling process, thereby extending the contact time between the parts and the spraying time, thus improving the spraying efficiency. Furthermore, since electroplating mainly occurs near the bottom of the spray gun, the solution flowing from top to bottom can also significantly improve the cathode current efficiency. During this process, because a guide plate is fixedly connected to the support shaft, under the guidance of the guide plate, a portion of the solution flows along the inner wall of the spray gun, thus effectively solving the problem of slow solution circulation on the inner wall of the spray gun.

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] A spraying cylinder 9 is fixedly connected between two external gear rings 8. A baffle 7 and a spraying cylinder 9 are rotatably connected. A reinforcing ring 10 is fixedly connected between the spraying cylinder 9 and the external gear rings 8. A groove is provided on the baffle 7. An inlet / outlet gate 12 is rotatably connected in the groove. The baffle 7 and the inlet / outlet gate 12 are rotatably connected by a hinge 11. A magnetic block 13 is fixedly connected to the side wall of the inlet / outlet gate 12 near the mounting base 5. A limit adjustment device is provided on the baffle 7. The limit adjustment device includes a rotating rod 14. The rotating rod 14 is rotatably connected to the side wall of the baffle 7. A stop rod 15 is fixedly connected inside the rotating rod 14.

[0018] An adjusting rod 16 is fixedly connected to one side wall of the stop bar 15. A loading and unloading rotation adjustment device is provided between one end of the bracket 1 and the mounting base 5. The loading and unloading rotation adjustment device includes two side plates 17. Both side plates 17 are fixedly connected to one side wall of the bracket 1. A winding roller is rotatably connected between the two side plates 17. A connecting rope 18 is wound on the winding roller. One end of the connecting rope 18 is fixedly connected to one of the mounting bases 5. A second drive motor is fixedly connected to one side wall of one of the side plates 17. The output end of the second drive motor passes through the side plate 17 and is fixedly connected to the winding roller.

[0019] The bracket 1 is equipped with a spraying drive device, which includes a first drive motor 19. A drive shaft 20 passing through the bracket 1 is fixedly connected to the output end of the first drive motor 19. Two first gears 21 are symmetrically fixedly connected to the drive shaft 20. The two first gears 21 are arranged in a one-to-one correspondence with two external gear rings 8. The outer side wall of the external gear rings 8 is provided with teeth that mesh with the first gears 21. The spray tank 2 is equipped with a material replenishment device, which includes a base plate 22. The base plate 22 is fixedly connected to the inner side wall of the spray tank 2. Multiple adapters 23 are rotatably connected inside the base plate 22. A drive shaft 24 is fixedly connected to each of the multiple adapters 23. A fan blade 25 is fixedly connected to one end of the drive shaft 24.

[0020] Two connectors 26 are symmetrically fixedly connected to the inner wall of the spray tank 2. A worm gear 27 is rotatably connected between the two connectors 26. A second gear 28 that meshes with the worm gear 27 is fixedly connected to the transmission shaft 24. Two worm wheels 29 are symmetrically fixedly connected to the worm gear 27. The two worm wheels 29 are arranged in a one-to-one correspondence with the two external gear rings 8. The worm wheels 29 are meshed with the external gear rings 8. Multiple fixing plates 30 are symmetrically fixedly connected to the outer wall of the support shaft 6. A guide plate 31 is fixedly connected to the end of the multiple fixing plates 30 away from the support shaft 6. The side wall of the guide plate 31 away from the support shaft 6 is arc-shaped.

[0021] In use, the hydraulic cylinder is first controlled to lift the support 1 until the spray cylinder 9 moves above the spray tank 2. Then, the second drive motor is started in reverse. The output end of the second drive motor drives the winding roller in reverse to release the connecting rope 18. Since one of the mounting seats 5 is rotatably connected to the support 1 through the support plate 3 and the mounting plate 4, the entire spray cylinder 9 rotates counterclockwise downward around the pivot on the support plate 3 as the connecting rope 18 is released. After rotating to a suitable tilt angle, the second drive motor is turned off, and the inlet end of the container storing the parts is aligned with the lowest end of the spray cylinder 9. The material inlet / outlet gate 12 is opened, and then the adjusting rod 16 is rotated around the rotating rod 14 so that the stop rod 15 does not block the material inlet / outlet gate 12. Then the magnetic block 13 is pulled so that the material inlet / outlet gate 12 rotates around the hinge 11 to open. The magnetic block 13 is rotated to contact the mounting base 5 so that the magnetic block 13 can be magnetically attracted and fixed on the mounting base 5, keeping the material inlet / outlet gate 12 in the open state. After the material inlet / outlet gate 12 is opened, the parts that have been sprayed and processed in the spraying cylinder 9 can slide out along the component force in the direction of the inclined inner wall of the spraying cylinder 9 by their own gravity and fall into the storage container, completing the unloading. After the material is unloaded, press down the inlet / outlet gate 12 that was just opened, so that the inlet / outlet gate 12 overcomes the magnetic force between the magnet 13 and the mounting base 5 and rotates around the hinge 11 to reset. Then rotate the adjusting rod 16 around the rotating rod 14 again, and block the inlet / outlet gate 12 with the help of the stop rod 15 to limit and fix the inlet / outlet gate 12 and close it. Then open the inlet / outlet gate 12 at the highest point on the spraying cylinder 9 in the same way, so that the parts to be sprayed can be loaded into the spraying cylinder 9. After the material is loaded, close the inlet / outlet gate 12 again, and then start the second drive motor to rotate forward. The output end of the second drive motor drives the winding roller to rotate forward and take in the connecting rope 18, thereby pulling one of the mounting seats 5, so that the spraying cylinder 9 rotates around the shaft on the support plate 3 until it returns to a horizontal state. At this time, the two external gear rings 8 respectively contact and mesh with the two first gears 21. Then control the hydraulic cylinder to drive the bracket 1 to move down, so that the spraying cylinder 9 enters the spraying pool 2 until the two external gear rings 8 abut against the two worm gears 29 and mesh with them. Then start the first drive motor 19. The output end of the first drive motor 19 drives the two first gears 21 to rotate through the drive shaft 20. Since the baffle 7 is fixedly connected to the support shaft 6, and the external gear ring 8 is rotatably connected to the outer wall of the baffle 7, and the support shaft 6 is rotatably connected to the support plate 3 through the mounting seat 5 at one end, it is limited to rotating only around the shaft. Therefore, when the first gear 21 drives the external gear ring 8 to rotate, the external gear ring 8 cannot drive the baffle 7 and the support shaft 6 to rotate together. Thus, the support shaft 6 and the baffle 7 are essentially fixed, meaning that the positions of the inlet and outlet gates 12 on the two baffles 7 remain unchanged, facilitating subsequent loading and unloading operations. Compared to the traditional side-mounted loading and unloading method, this method offers advantages over traditional side-mounted loading and unloading methods. There is no need to rotate the spray cylinder 9 to adjust the position of the inlet and outlet gate 12, so it is simpler and more convenient to use. At the same time, since the connection between the support shaft 6 and the baffle 7 is not located at the center of the baffle 7, the inlet and outlet gate 12 can be set to be larger, making it easier to load and unload materials. Furthermore, since the position of the support shaft 6 is higher than the central axis height of the spray cylinder 9, the parts inside the spray cylinder 9 are less likely to be blocked by the support shaft 6 during the spraying and tumbling process, so there is less interference with the spraying process of the parts inside the spray cylinder 9, which allows more parts to be loaded and thus more parts to be processed at one time. When the first gear 21 drives the spray cylinder 9 to rotate via the external gear ring 8 to spray the parts inside the spray cylinder 9, the external gear ring 8 can also drive the worm gear 29 to rotate, thereby driving the worm 27 to rotate. The worm 27 can drive multiple fan blades 25 to rotate together through meshing with multiple second gears 28. Using the multiple fan blades 25 rotating together, a vertically downward water flow is generated in the spray tank 2 facing the bottom of the spray cylinder 9. The rotating fan blades 25 generate a suction effect on the bottom of the spray cylinder 9, thereby drawing the solution inside the spray cylinder 9 out through the sieve holes at the bottom of the spray cylinder 9 and creating a negative pressure environment inside the spray cylinder 9, so that the external solution can quickly compensate and enter the spray cylinder 9 through the sieve holes in the upper part of the spray cylinder 9. By accelerating the flow between the solution inside and outside the spraying cylinder 9, the replenishment of cations in the solution inside the spraying cylinder 9 is accelerated during the spraying process. Moreover, the downward flow of the solution inside the spraying cylinder 9 can accelerate the falling speed of the parts during the tumbling process, thereby extending the contact time between the parts and the spraying time, thus improving the spraying efficiency. Furthermore, since electroplating mainly occurs near the bottom of the spraying cylinder 9, the downward flow of the solution can also significantly improve the cathode current efficiency. During this process, because the guide plate 31 is fixedly connected to the support shaft 6, under the guidance of the guide plate 31, a portion of the solution flows along the inner wall of the spraying cylinder 9, thereby effectively solving the problem of slow solution circulation on the inner wall of the spraying cylinder 9.
