[0027] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0028] like Figure 1-4 As shown, this utility model provides a technical solution: an intelligent grinding and polishing device for industrial robot processing, including a body 1 and a grinding roller 4. A servo motor that can drive the grinding roller 4 to rotate is installed inside the body 1. The grinding roller 4 rotates on one side of the body 1. A vision sensor 5 is installed on the outer surface of the body 1 near the grinding roller 4. A cleaning device 2 is installed at the bottom of the body 1. The cleaning device 2 includes a collection box 21, which is fixed to one side of the bottom of the body 1. An air extraction hole 23 is opened on one side of the inner wall of the collection box 21. A filter plate 22 is fixedly connected to the top of the inner wall of the collection box 21. Filters are provided on the inner walls of both the filter plate 22 and the air extraction hole 23. The body 1 is equipped with a negative pressure fan 24. One end of the negative pressure fan 24 is connected to an air extraction hole 23 on one side of the inner wall of the collection box 21 through a pipe. A collection tray 25 is slidably inserted into the inner wall of the collection box 21. By setting up the collection box 21, the collection tray is first inserted into the inside of the collection box on one side. When the grinding and polishing device is used to grind and polish the surface of the industrial robot's shell, the mechanical equipment clamps the shell workpiece of the industrial robot and brings the shell workpiece close to the grinding roller 4. The operating parameters of the body 1 are adjusted through the control box on one side of the body 1. When the vision sensor 5 detects that the workpiece is close to the surface of the grinding roller 4, the servo motor inside the body 1 is driven to operate and drive the grinding. The rotating grinding roller 4 polishes the outer surface of the workpiece. Simultaneously, the negative pressure fan 24 inside the machine body 1 operates, generating airflow that draws metal debris generated during grinding, near the top of the collection box 21, towards the collection box 21. The debris passes through the filter plate 22 on the surface of the collection box 21 and is collected on the collection tray 25 inside. The filter at the air extraction hole 23 prevents metal debris from entering the pipes of the negative pressure fan 24. After grinding, the clamping device controls the workpiece to move away from the surface of the grinding roller 4. A sensor detecting this movement will stop the servo motor. The negative pressure fan 24 is stopped by controlling the control box, and the collection tray 25 is pulled out to clean the metal debris on the surface of the collection tray 25. By setting up the cleaning device 2, a collection box 21 is installed on the lower side of the outer surface of the machine body 1 near the grinding roller 4. During the grinding and polishing of the shell workpiece of the industrial robot, the negative pressure fan 24 is controlled to operate. The negative pressure fan 24 generates wind force to draw the metal debris generated during the grinding process towards the collection box 21, so that the metal debris enters the collection box 21 for collection. This minimizes the splashing of metal debris in the processing environment, which affects the cleanliness of the processing environment and improves the practicality of the grinding and polishing device.

[0029] Specifically, such as Figure 2-4As shown, a pull rod 210 is fixedly connected to one side of the collection tray 25. The outer surface of the pull rod 210 is U-shaped. Holding the outer surface of the U-shaped pull rod 210 makes it easier to pick up the collection tray 25 and control the collection tray 25 to be inserted into or pulled out of the collection box 21.

[0030] Specifically, such as Figure 2-5 As shown, the collection box 21 has grooves 26 on both sides. A sliding rod 27 is slidably connected to the inner wall of the groove 26. A brush rod 28 is fixedly connected to one side of the sliding rod 27. Several hard brushes are provided on one side of the brush rod 28. After the polishing device is used, the sliding rod 27 can be pushed at the top of the collection box 21 to control the sliding rod 27 to slide on the inner wall of the groove 26, which will drive the brush rod 28 to slide on the top side of the filter screen plate 22. The hard brushes on one side of the brush rod 28 can push the debris left on the surface of the filter screen plate 22 into the collection box 21. A handle 29 is fixedly connected to the top of the sliding rod 27. A rubber sleeve is provided on the outer surface of the handle 29. Holding the handle 29 on the rubber sleeve makes it easier to control the movement of the sliding rod 27 and prevents the hand from slipping.

[0031] Specifically, such as Figure 1-3 As shown, a positioning device 3 is provided on one side of the collection box 21. The positioning device 3 includes a rectangular block 31, a round rod 32 slidably connected to the inner wall of the rectangular block 31, a locking block 33 fixedly connected to the bottom end of the round rod 32, and a spring 34 provided at the top end of the locking block 33. The upper and lower ends of the spring 34 are fixedly connected to the bottom end of the rectangular block 31 and the top end of the locking block 33, respectively. A groove block 35 is fixedly connected to one side of the collection tray 25. A groove is provided at the top end of the groove block 35. When the collection tray 25 is inserted into the collection box 21, one end of the groove block 35 will contact the bottom end of the locking block 33 before the collection tray 25 is fully inserted into the collection box 21. Moving the collection tray 25 will... Pushing the locking block 33 causes the round rod 32 to slide upward on the inner wall of the rectangular block 31 and compress the spring 34. After the collecting tray 25 is fully inside the collecting box 21, the spring 34 returns to its original state and pushes the locking block 33 and the round rod 32 downward to lock the locking block 33 into the groove at the top of the slot block 35. This further fixes the position of the collecting tray 25 inside the collecting box 21, and minimizes the risk of the collecting tray 25 moving on its own due to vibration during the operation of the polishing device. When removing the collecting tray 25, pull the round rod 32 to move the locking block 33 upward so that the locking block 33 is away from the groove at the top of the slot block 35. Then pull the collecting tray 25 to remove it.

[0032] Specifically, such as Figure 2-3As shown, the top edge of the end of the slot block 35 away from the collection tray 25 is a slope, and the bottom surface of the locking block 33 is an arc surface. By setting the top edge of the end of the slot block 35 away from the collection tray 25 to be a slope and the bottom surface of the locking block 33 to be an arc surface, it is easier to push the locking block 33 to move when the end of the slot block 35 contacts the surface of the locking block 33, and they will not get stuck together.

[0033] Specifically, such as Figure 1 and Figure 6 As shown, the machine body 1 is equipped with an intelligent control module, which includes an image processing module, a data processing module, and a control panel. The vision sensor 5 is electrically connected to the image processing module, and the control panel is electrically connected to the servo motor. When the grinding and polishing device is working, the vision sensor 5 collects image information at the grinding roller 4, then transmits the image information to the image processing module for noise reduction and amplification, then transmits the image to the data processing module to convert it into an electrical signal, and then transmits the electrical signal to the control panel. The control panel issues commands to control the servo motor to operate or stop.

[0034] The working principle of this utility model is as follows:

[0035] S1. When using a grinding and polishing device to grind and polish the surface of the industrial robot's shell, first insert the collection tray 25 into the inside of the collection box 21 on one side. Before the collection tray 25 is fully inside the collection box 21, one end of the slot block 35 will contact the bottom side of the locking block 33. Moving the collection tray 25 will push the locking block 33, causing the round rod 32 to slide upward on the inner wall of the rectangular block 31 and compress the spring 34. After the collection tray 25 is fully inside the collection box 21, the spring 34 returns to its original state, pushing the locking block 33 and the round rod 32 downward to lock the locking block 33 into the groove at the top of the slot block 35, further fixing the position of the collection tray 25 inside the collection box 21. Then, the mechanical equipment clamps the shell workpiece of the industrial robot and brings the shell workpiece close to the grinding roller 4. The operating parameters of the machine body 1 are adjusted through the control box on one side of the machine body 1. When the vision sensor 5 detects that the workpiece is close to the surface of the grinding roller 4, the servo motor inside the machine body 1 is driven to rotate the grinding roller 4. The rotating grinding roller 4 polishes the outer surface of the workpiece. At the same time, the negative pressure fan 24 inside the machine body 1 is operated. The negative pressure fan 24 generates air force to draw the metal debris generated during the grinding process near the top of the collection box 21 towards the collection box 21. The metal debris enters the collection tray 25 inside the collection box 21 through the filter plate 22 on the surface of the collection box 21 for collection. The filter at the air extraction hole 23 can block the metal debris and prevent the metal debris from entering the pipe of the negative pressure fan 24. After the grinding is completed, the clamping device controls the workpiece to move away from the surface of the grinding roller 4. When the test paper sensor detects that the workpiece is away from the surface of the grinding roller 4, it controls the servo motor to stop operating, and then controls the negative pressure fan 24 to stop operating through the control box.

[0036] S2. Pull the round rod 32 to move the locking block 33 upward so that the locking block 33 is away from the groove at the top of the slot block 35. Then, hold the outer surface of the U-shaped pull rod 210 and pull the collection plate 25 to remove the collection plate 25 and clean the metal debris inside the collection plate 25.
