Description

Technical Field

[0001] This utility model relates to the field of automatic polishing technology, specifically to an automatic polishing device with an intelligent robotic arm. Background Technology

[0002] In the production process of wood panels, such as recycled wood processing, furniture manufacturing, and wood product production, sanding the edges of the panels is usually a necessary step to remove burrs and ensure that the edges are smooth and flat, which facilitates subsequent processing.

[0003] Currently, most polishing processes use belt sanders for grinding, combined with six-axis robotic arms for automatic feeding or rotation. However, most of these robotic arms are fixed in position during use, which greatly limits their range of motion. In addition, the waste generated during grinding has a serious impact on the environment. Utility Model Content

[0004] The purpose of this invention is to provide an automatic grinding device with an intelligent robotic arm to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a feeding rack and a soundproof enclosure. A support frame is connected to the inner side of the feeding rack, and a servo motor is connected to the bottom end of the support frame. A traction mechanism is connected to the output end of the servo motor, and an electric guide rail is connected to one side of the traction mechanism. A connecting base is connected to the moving end of the electric guide rail, and a robotic arm is connected to the top of the connecting base. A suction cup claw is connected to the working end of the robotic arm. A dust collection box is connected to one side of the feeding rack, and a processing chamber is connected to the top of the dust collection box. Grinding mechanisms are connected to both sides of the processing chamber. A filter screen is connected to one side of the inner wall of the dust collection box, and an air pump is connected to one side of the dust collection box. The air inlet of the air pump is connected and communicates with the dust collection box.

[0006] Preferably, the traction mechanism includes a first swing arm, a middle rotating arm, and a connecting arm. Gear heads are connected to the ends of the first swing arm, the middle rotating arm, and the connecting arm that are close to each other and mesh with each other. A card holder is connected to the ends of the first swing arm, the middle rotating arm, and the connecting arm that are close to each other. A limit strip is connected to the bottom end of the card holder. A limit guide is slidably provided at the bottom end of the limit strip. The limit guide is slidably provided inside the loading rack.

[0007] By adopting the above technical solution, the electric guide rail can be driven to reciprocate along the loading rack, thereby adjusting the working position of the robotic arm. With the cooperation of the electric guide rail, the working range and work content of the robotic arm can be effectively increased, and automation can be improved.

[0008] Preferably, a connecting shaft is connected to the end of the connecting arm away from the central rotating arm, a roller is rotatably mounted on the top of the connecting shaft, a connecting frame is connected to the bottom of the electric guide rail, and the roller is rotatably mounted inside the connecting frame.

[0009] By adopting the above technical solution, when the traction mechanism drives the electric guide rail to move back and forth, the rolling between the roller and the connecting frame can effectively ensure a smooth effect and reduce resistance.

[0010] Preferably, slide rails are connected to the bottom ends of both sides of the electric guide rail, and a slide groove is opened at the top of the feeding rack corresponding to the slide rail;

[0011] By adopting the above technical solution, the electric guide rail is effectively supported. Through the sliding effect between the slide rail and the slide groove, the smoothness of the traction mechanism's movement of the electric guide rail can be further guaranteed.

[0012] Preferably, the dust collection box has a chip extraction hole at the top corresponding to the middle position of the processing chamber, and a cleaning door panel is provided on one side;

[0013] By adopting the above technical solution, the internal filter can be removed by opening the cleaning door panel, and the debris inside the dust collection box can be cleaned. At the same time, the debris generated during grinding can be collected through the chip extraction hole.

[0014] Preferably, the grinding mechanism includes a mounting frame slidably disposed on both sides of the processing chamber and a fixed frame fixedly disposed on both sides of the processing chamber. Two support rollers are rotatably disposed on the inner side of each mounting frame. A grinding belt is sleeved and connected between the support rollers. A drive motor is connected to the bottom end of the mounting frame. The output end of the drive motor passes through the mounting frame and is connected to one of the support rollers. A sliding frame is connected to the side of the mounting frame that is far apart from each other. Multiple sets of compression springs are connected to the inner side of each sliding frame. The other end of each compression spring is connected to the fixed frame.

[0015] By adopting the above technical solution, both sides of one side of the board can be polished at the same time, which effectively improves the processing efficiency. The compression springs on both sides can ensure the fit between the sanding belt and the board, and ensure the polishing effect.

[0016] Preferably, the processing chamber has a feed inlet at the center of its top, and the processing chamber and the grinding mechanism are located inside a soundproof enclosure;

[0017] By adopting the above technical solutions, the exposed grinding space can be greatly reduced and debris can be minimized by setting the feed inlet. Furthermore, the soundproof enclosure can further reduce debris and reduce the impact of grinding noise.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] The traction mechanism and electric guide rails significantly increase the range of motion of the robotic arm. It can directly perform grinding work after gripping the board with suction cups, reducing unnecessary steps. It features automatic loading and unloading and automatic grinding. Two grinding mechanisms can grind both sides of the board simultaneously, effectively improving work efficiency. The inclusion of a processing chamber and a dust collection chamber effectively reduces debris flying. The air pump and filter work together to collect debris into the dust collection chamber, reducing environmental pollution. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4This utility model provides a technical solution: including a feeding rack 1 and a soundproof cover 111. A support frame is connected to the inner side of the feeding rack 1, and a servo motor 2 is connected to the bottom end of the support frame. A traction mechanism is connected to the output end of the servo motor 2, and an electric guide rail 10 is connected to one side of the traction mechanism. A connecting base 13 is connected to the moving end of the electric guide rail 10. A robotic arm 14 is connected to the top of the connecting base 13. A suction cup claw 15 is connected to the working end of the robotic arm 14. A dust collection box 16 is connected to one side of the feeding rack 1. A processing chamber 17 is connected to the top of the dust collection box 16. Grinding mechanisms 18 are connected to both sides of the processing chamber 17. A filter screen 19 is connected to one side of the inner wall of the dust collection box 16. An air pump 20 is connected to one side of the dust collection box 16, and the air inlet of the air pump 20 is connected to the dust collection box 16.

[0027] Reference Figure 3 As shown, the traction mechanism includes a first swing arm 3, a middle rotating arm 4, and a connecting arm 5. Gear heads 7 are connected to the ends of the first swing arm 3, the middle rotating arm 4, and the connecting arm 5 that are close to each other, and they mesh with each other. A clamp 6 is connected to the ends of the first swing arm 3, the middle rotating arm 4, and the connecting arm 5 that are close to each other. A limit strip 8 is connected to the bottom end of the clamp 6. A limit guide frame 81 is slidably mounted on the bottom end of the limit strip 8. As can be seen from the attached drawing, a guide hole is formed on the surface of the limit guide frame 81 corresponding to the limit strip 8. A sliding hole is formed on the inner side of the loading rack 1 corresponding to the guide frame 81. The limiting guide frame 81 is slidably set inside the loading frame 1. The drive 2 drives the first swing arm 3 to rotate. When the first swing arm 3 rotates, it drives the intermediate rotating arm 4 to rotate in the card holder 6 through the meshing of the gear head 7 between the first swing arm 3 and the intermediate rotating arm 4. It also drives the connecting arm 5 to rotate in the same way. When rotating, the limiting strip 8 below the card holder 6 slides along the guide hole on the limiting guide frame 81. The limiting strip 8 is adjustable. It slides along the limiting guide frame 81 without rotating, thereby ensuring the transmission effect between the first swing arm 3, the intermediate rotating arm 4 and the connecting arm 5.

[0028] A connecting shaft 9 is connected to the end of the connecting arm 5 away from the intermediate rotating arm 4. A roller 12 is rotatably mounted on the top of the connecting shaft 9. A connecting frame 11 is connected to the bottom of the electric guide rail 10. The roller 12 is rolled inside the connecting frame 11. When the servo motor 2 drives the traction mechanism, the roller 12 will roll along the connecting frame 11 when the connecting arm 5 is pulled or pushed through the connection between the roller 12 and the connecting frame 11, thereby ensuring the traction effect of the connecting arm 5 and meeting the displacement requirements of the end point of the connecting arm 5.

[0029] The electric guide rail 10 is connected to slide rails at both bottom ends. The top of the loading rack 1 is provided with a slide groove corresponding to the slide rail. When the electric guide rail 10 is driven by the traction mechanism, it moves along the slide groove through the slide rail, thereby adjusting the position of the upper robotic arm 14.

[0030] Reference Figure 4 As shown, the top of the dust collection box 16 is provided with a chip extraction hole corresponding to the middle position of the processing chamber 17, and a cleaning door panel 21 is provided on one side. The center of the top of the processing chamber 17 is provided with a feeding port. The processing chamber 17 and the grinding mechanism 18 are located inside the sound insulation cover 111. The processing chamber 17 is equipped with a plug head, and a flexible magnet is connected to one side of the filter screen 19. It can be quickly installed and removed by magnetic attraction to clean the collected debris and the filter screen 19. The board is grasped by the suction cup claw 15 by 14 and one side of the board is inserted through the feeding port. The grinding mechanisms 18 on both sides grind the two sides of the end face of the board.

[0031] The grinding mechanism 18 includes mounting frames 181 slidably disposed on both sides of the processing chamber 17 and fixed frames 182 fixedly disposed on both sides of the processing chamber 17. Two support rollers 183 are rotatably disposed inside each mounting frame 181, and a grinding belt 184 is sleeved and connected between the support rollers 183. A drive motor 185 is connected to the bottom end of the mounting frame 181, and the output end of the drive motor 185 passes through the mounting frame 181 and is connected to one of the support rollers 183. A sliding frame 186 is connected to each side of the mounting frame 181 that is furthest from each other. Multiple sets of compression springs 187 are connected to the inner side of each sliding frame 186. The other end of the compression spring 187 is connected to the fixed frame 182, which drives the drive motor 185 to rotate the support roller 183, thereby driving the grinding belt 184 to operate. Since the fixed frame 182 is fixedly set on one side of the mounting frame 181, it provides a support point for the compression spring 187. Through the elasticity of the compression spring 187, the two mounting frames 181 are pushed in opposite directions. When the plate enters through the feed port above the processing chamber 17, the grinding belt 184 grinds one side and two sides of the plate. The chip extraction hole is located directly below the middle of the two grinding belts 184, which can extract the grinding debris.

[0032] The implementation principle of this application is as follows: When using this utility model, the plate to be polished is stacked on one side of the loading rack 1. The electric guide rail 10 is pulled by the traction mechanism, thereby driving the position of the robotic arm 14 to the side of the stacked plate. The robotic arm 14 is driven to pick up the plate by the suction claw 15. Then the traction mechanism reverses and pushes the robotic arm 14 towards the sound insulation cover 111. The position of the plate is adjusted by the robotic arm 14 so that the plate can be inserted from the feed port side of the processing chamber 17. The polishing mechanisms 18 on both sides polish the edge of the plate. The air pump 20 is started to draw air from the dust collection box 16 to generate negative pressure. The chips generated during polishing are then extracted through the chip extraction hole. The polishing part is located inside the processing chamber 17, so the chip extraction effect can be effectively guaranteed and dust can be prevented from flying out. At the same time, the sound insulation cover 111 can further control the impact of flying dust on the environment and reduce the noise generated during polishing. After one side of the plate is polished, the polished edge can be adjusted directly by the robotic arm 14 for another operation.
