Description

Technical Field

[0001] The invention relates to the field of automobile parts processing, and in particular to a robot for automobile parts processing. Background Art

[0002] With the improvement of automation, the use of robots for grinding auto parts is gradually increasing. However, when using robots to grind auto parts, the debris generated by grinding will splash everywhere. The debris is easy to splash to the joints of the robot, causing the joints of the robot to be worn by the debris when moving, reducing the service life of the robot.

[0003] When a robot is used for grinding, a protective cover is usually used to isolate the grinding area from the outside world, so that the debris generated during the grinding process will not splash around, and when cleaning the debris later, the personnel can clean the debris together; however, when grinding the car door shell, since the car door shell is a special-shaped part, the protective cover cannot be completely fitted with the surface of the car door shell during the grinding process, so that during the grinding process, there is still a situation where the debris splashes outward. Summary of the invention

[0004] In order to overcome the disadvantage that when grinding the door shell, the protective cover cannot be completely fitted with the surface of the door shell, so that during the grinding process, debris still splashes outward, the present invention provides a robot for processing automobile parts.

[0005] The technical solution of the present invention is: a robot for processing automobile parts, including a robot arm, an electric telescopic rod, a motor and a grinding block; the robot arm is fixedly connected to the electric telescopic rod; the telescopic part of the electric telescopic rod is fixedly connected to the motor; the motor output shaft is fixedly connected to the grinding block; an identifier is arranged on the robot arm; it also includes a sleeve rod, an electric guide rail, a shielding cover, shielding bristles and a retraction assembly; the robot arm is fixedly connected to the sleeve rod, and the telescopic part of the electric telescopic rod passes through the sleeve rod; the sleeve rod is fixedly connected to the electric guide rail; the electric guide rail is connected to a shielding cover for shielding debris; the shielding cover is fixedly connected to a plurality of shielding bristles, and the shielding bristles are located below the bottom surface of the grinding block; the electric guide rail is connected to a retraction assembly for retracting the shielding cover.

[0006] Furthermore, the retracting assembly includes a moving block, a rib plate and a rubber sheet; the electric guide rail is slidably connected to a plurality of moving blocks; each moving block is fixedly connected to a rib plate; each two adjacent rib plates are commonly fixedly connected to a rubber sheet, and all the rib plates and rubber sheets together form a shielding cover.

[0007] Furthermore, it also includes a support ring; the electric guide rail is fixedly connected to the support ring through a connecting rod, and the rib plate is slidably connected to the support ring.

[0008] Furthermore, the shielding bristles are arranged to be inclined from the center of the shielding cover to the surrounding areas.

[0009] Furthermore, it also includes a circular tube, a connecting tube and a suction tube; the robotic arm is provided with a circular tube, and the circular tube is connected to an external suction mechanism; the telescopic part of the electric telescopic rod is fixedly connected with a connecting tube; the connecting tube is connected to a plurality of suction tubes, and the circular tube passes through two ribs and is connected to the connecting tube.

[0010] Furthermore, it also includes magnetic blocks; each rib plate is fixedly connected with two magnetic blocks, and the magnetic blocks on each rib plate are on the same horizontal line.

[0011] Furthermore, the width of the magnet block is similar to the width of the rib plate.

[0012] Furthermore, it also includes an electric push rod and an extrusion sheet; the shielding cover is fixedly connected to a plurality of electric push rods, each of which is fixedly connected to a corresponding rib plate; the telescopic part of the electric push rod is rotationally connected to the extrusion sheet through a torsion spring.

[0013] Furthermore, adjacent extruded sheets are distributed in a stacked and staggered manner.

[0014] Furthermore, it also includes a bolt knob and a coarse grinding sheet; the grinding block is rotatably connected to the bolt knob; the bolt knob is rotatably connected to the coarse grinding sheet, and the coarse grinding sheet is slidably connected to the grinding block. Beneficial Effects

[0015] The grinding area of ​​the grinding block is shielded by the shielding hood and the shielding brush bristles, and the shielding brush bristles can adapt to the uneven surface of the door shell, fully intercept the debris generated by grinding, and prevent the debris from splashing everywhere, which increases the difficulty of subsequent cleaning; and the shielding brush bristles are inclined from the center of the shielding hood to the surrounding areas. When the robotic arm drives the shielding brush bristles to move down and contact the surface of the automotive accessories, the robotic arm continues to drive the shielding brush bristles to move, and the shielding brush bristles will bend toward the surrounding areas to prevent the shielding brush bristles from bending toward the center of the grinding block, so that the shielding brush bristles will contact the grinding block.

[0016] When the shielding cover is unfolded normally, the ribs fit together. The magnetic attraction of the magnetic block allows the ribs to fit tightly together, preventing only one end of the rib from being connected to the electric guide rail through the moving block while the other end lacks connection, which makes it easy for small gaps to appear between the ribs during the use of the shielding cover, and then debris is easily splashed out during the subsequent process of shielding debris.

DETAILED DESCRIPTION

[0025] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0026] Embodiment 1: A robot for processing automobile parts, such as Figure 1-Figure 7 As shown, it includes a mechanical arm 1, an electric telescopic rod 2, a motor 3 and a grinding block 4; the mechanical arm 1 is fixedly connected to the electric telescopic rod 2; the telescopic part of the electric telescopic rod 2 is fixedly connected to the motor 3; the output shaft of the motor 3 is fixedly connected to the grinding block 4; an identifier is provided on the mechanical arm 1;

[0027] It also includes a sleeve rod 5, an electric guide rail 6, a shielding cover 7, shielding bristles 8 and a retraction component; the robotic arm 1 is fixedly connected to the sleeve rod 5, and the telescopic part of the electric telescopic rod 2 passes through the sleeve rod 5; the sleeve rod 5 is fixedly connected to the electric guide rail 6; the electric guide rail 6 is connected to the shielding cover 7; a number of shielding bristles 8 are fixedly connected to the bottom of the shielding cover 7, and the shielding bristles 8 are located below the bottom surface of the grinding block 4; the electric guide rail 6 is connected to the retraction component.

[0028] The retracting assembly includes a moving block 71, a rib plate 72 and a rubber sheet 73; the electric guide rail 6 is slidably connected to a plurality of moving blocks 71; each moving block 71 is fixedly connected to a rib plate 72; each two adjacent rib plates 72 are commonly fixedly connected to a rubber sheet 73, and all the rib plates 72 and rubber sheets 73 together form a shielding cover 7.

[0029] It also includes a support ring 9; the electric guide rail 6 is fixedly connected to the support ring 9 through a connecting rod, and the rib plate 72 is slidably connected to the support ring 9.

[0030] The shielding bristles 8 are inclined from the center of the shielding cover 7 to the surrounding areas. When the robot arm 1 drives the shielding bristles 8 to move downward and contact the surface of the door shell, the robot arm 1 continues to drive the shielding bristles 8 to move, and the shielding bristles 8 will bend toward the surrounding areas to prevent the shielding bristles 8 from bending toward the center of the grinding block 4, so that the shielding bristles 8 will contact the grinding block 4 and affect the normal grinding of the grinding block 4.

[0031] It also includes a circular tube 101, a connecting tube 102 and a suction tube 103; the robotic arm 1 is provided with a circular tube 101, and the circular tube 101 is connected to an external suction mechanism; the telescopic part of the electric telescopic rod 2 is fixedly connected with a connecting tube 102; the connecting tube 102 is connected with ten suction tubes 103 distributed in a circular array, and the circular tube 101 passes through two ribs 72 to be connected with the connecting tube 102.

[0032] It also includes magnetic blocks 111; each rib plate 72 is fixedly connected to two magnetic blocks 111, and the magnetic blocks 111 on each rib plate 72 are on the same horizontal line.

[0033] The width of the magnetic block 111 is similar to that of the rib plate 72 . When the rib plate 72 moves to shrink and open the shielding cover 7 , the moved rib plate 72 can still be fixed by the magnetic attraction of the magnetic block 111 .

[0034] When processing the door shell, the door shell that needs to be polished is first manually fixed in the working area of ​​the robot arm 1, and then the robot arm 1 is controlled to work. The robot arm 1 identifies and locates through the identifier, and drives the electric telescopic rod 2, the motor 3 and the polishing block 4 to move, so that the bottom surface of the polishing block 4 contacts the surface of the door shell that needs to be polished. Subsequently, the motor 3 is controlled to drive the polishing block 4 to rotate, and the robot arm 1 is controlled to move to polish the surface of the door shell.

[0035] However, the debris generated by grinding will splash everywhere, increasing the difficulty of subsequent cleaning, and it is easy to splash between the joints of the robot arm 1. The debris will cause additional wear and tear on the robot arm 1 when it moves, reducing the service life of the robot arm 1, and the door shell is a special-shaped part with an uneven surface, and the existing protective cover cannot block the splashing of debris. Therefore, when the robot arm 1 drives the grinding block 4 to move and contact the surface of the door shell, the robot arm 1 simultaneously drives the shielding cover 7 and the shielding brush 8, as well as other connected parts to move together, and the shielding brush 8 is located below the bottom surface of the grinding block 4. When the robot arm 1 drives When the grinding block 4 contacts with the surface of the door shell, the shielding bristles 8 contact with the surface of the door shell first, and then the grinding block 4 contacts with the surface of the door shell again. At this time, the shielding cover 7 and the shielding bristles 8 shield the grinding block 4. Subsequently, the mechanical arm 1 is controlled to drive the grinding block 4 to move on the surface of the door shell, and the motor 3 is controlled to drive the grinding block 4 to rotate and grind. The generated debris is blocked by the shielding cover 7 and the shielding bristles 8, and the debris cannot splash outward. The grinding area of ​​the grinding block 4 is shielded by the shielding cover 7 and the shielding bristles 8, and the shielding bristles 8 can adapt to the uneven surface of the door shell. The shielding brush 8 is arranged to be inclined from the center of the shielding cover 7 to the surrounding areas. When the mechanical arm 1 drives the shielding brush 8 to move downward and contact the surface of the automobile accessory, the mechanical arm 1 continues to drive the shielding brush 8 to move, and the shielding brush 8 will bend toward the surrounding areas to prevent the shielding brush 8 from bending toward the central grinding block 4, so that the shielding brush 8 will contact the grinding block 4, which will not only cause wear to the shielding brush 8, but also make the shielding brush 8 easily involved in the grinding block 4 and the door shell surface. The surfaces are interlocked, affecting the normal grinding of the grinding block 4; at the same time, during the grinding process, the external suction mechanism is controlled to provide suction force for the suction tube 103 through the circular tube 101 and the connecting tube 102, so as to extract the dust and debris generated by the grinding block 4, reduce the debris remaining on the surface of the door shell, and improve the grinding effect of the grinding block 4; and when the grinding block 4 moves for grinding, it drives the shielding bristles 8 to move together, and the shielding bristles 8 can also be used to brush the polished surface of the door shell, so that it is convenient for the suction tube 103 to be extracted, thereby reducing the difficulty of subsequent cleaning of the door shell surface.

[0036] At the same time, when grinding the door shell, the side of the grinding block 4 is often used to grind the edge of the door shell. At this time, the shielding cover 7 and the shielding brush 8 will hinder the grinding block 4 from grinding the door shell edge, and directly control the electric telescopic rod 2 to drive the grinding block 4 to extend out of the shielding cover 7, and use the side of the grinding block 4 for grinding. The debris generated by the grinding cannot be blocked. Therefore, when it is necessary to grind the edge of the door shell, the two ribs 72 in contact with the circular tube 101 are used as a reference, and the moving block 71 is controlled to drive the two ribs 72 and other ribs 72, as well as the connected rubber sheet 73 to move back to back along the electric guide rail 6, so that the two ribs 72 that are in contact with each other at the circular tube 101 are separated, and the rubber sheet 73 is compressed to shrink and open the shielding cover 7, and at the same time, the electric telescopic rod 2 is controlled to drive the grinding block 4 and other connected parts to shrink and move to the inner side of the shielding cover 7 so that it can be as shown Figure 5 As shown, during subsequent grinding, the control robot arm 1 drives the grinding block 4 to contact and grind the edge of the door shell that needs to be grinded through the retracted and opened side of the shielding cover 7. At this time, during the grinding process of the grinding block 4, the shielding cover 7 can still shield the grinding area of ​​the grinding block 4 to reduce the splashing of debris outward; and when the rib plate 72 moves, the support ring 9 can provide additional support force to the rib plate 72 to ensure that the rib plate 72 as a whole can move along the electric guide rail 6.

[0037] At the same time, when the shielding cover 7 is normally unfolded, the ribs 72 fit together. The magnetic attraction of the magnetic block 111 allows the ribs 72 to fit tightly together, preventing only one end of the rib 72 from being connected to the electric guide rail 6 through the moving block 71, while the other end lacks connection, which makes it easy for small gaps to appear between the ribs 72 during the use of the shielding cover 7, and then in the subsequent process of shielding debris, debris is likely to splash out; and the width of the magnetic block 111 is similar to that of the rib 72. When the ribs 72 that fit together move and separate, and the shielding cover 7 is retracted and opened, the moved ribs 72 contact with the adjacent ribs 72, and at this time they can still be fixed by the magnetic attraction of the magnetic block 111.

[0038] Embodiment 2: Based on embodiment 1, Figure 3 and Figure 5-Figure 7 As shown, it also includes an electric push rod 201 and an extrusion sheet 202; the shielding cover 7 is fixedly connected with a plurality of electric push rods 201, and each electric push rod 201 is fixedly connected with the corresponding rib 72; the telescopic part of the electric push rod 201 is rotationally connected with the extrusion sheet 202 through a torsion spring.

[0039] Adjacent extrusion sheets 202 are distributed in a stacked and staggered manner. When the shielding cover 7 is retracted and opened, the extrusion sheets 202 can be stacked on each other to prevent the extrusion sheets 202 from hindering the retraction and opening of the shielding cover 7.

[0040] It also includes a bolt knob 41 and a coarse grinding sheet 42 ; the grinding block 4 is rotatably connected to the bolt knob 41 ; the bolt knob 41 is rotatably connected to the coarse grinding sheet 42 , and the coarse grinding sheet 42 is slidably connected to the grinding block 4 .

[0041] On the basis of the above-mentioned embodiment, when the shielding cover 7 is retracted and opened, the side edge of the door shell is polished. Figure 5 As shown, at this time, a large amount of debris will still be splashed to the left along the shielding opening of the shielding cover 7 to the outside, causing the debris to splash everywhere and disperse in the entire working area. Therefore, when the moving block 71 drives the rib plate 72 to move and shrinks and opens the shielding cover 7, a plurality of electric push rods 201 are controlled at the same time to drive the extrusion sheet 202 to move along the surface of the shielding cover 7. When the extrusion sheet 202 moves out of the shielding cover 7 and contacts the shielding bristles 8, the extrusion sheet 202 loses its restriction and rebounds and bends toward the center of the shielding cover 7 under the action of the torsion spring, and drives the shielding bristles 8 to shape toward the center of the shielding cover 7. The shielding bristles 8 bend toward the center of the shielding cover 7, intercepting and sealing the shielding opening of the shielding cover 7. When the side of the vehicle door shell is subsequently polished, the debris splashed into the shielding cover 7 is extracted through the suction tube 103, and the debris splashed outward from the shielding opening of the shielding cover 7 can continue to be intercepted by the shielding bristles 8, preventing the debris from splashing outward through the shielding opening of the shielding cover 7 and diffusing into the entire working area. The debris intercepted by the shielding bristles 8 eventually falls downward and gathers and falls below, which is also convenient for collecting and cleaning the debris during subsequent cleaning.

[0042] At the same time, when the subsequent grinding is completed and the shielding bristles 8 need to be cleaned, the electric push rod 201 is repeatedly controlled to drive the extrusion plate 202 to move and reset, thereby repeatedly squeezing and resetting the shielding bristles 8, so that the shielding bristles 8 are repeatedly shaken to shake off the debris intercepted inside.

[0043] Moreover, when polishing the door shell, it is usually necessary to perform rough polishing on the surface to remove the old paint layer, rust, etc. on the door shell surface, and then perform fine polishing to make the surface smooth and delicate. When the existing manipulator polishes the door shell, it is often necessary to disassemble and replace the polishing head for polishing, and the overall operation is cumbersome, which affects the polishing efficiency. Therefore, when it is necessary to perform rough polishing on the door shell, the bolt knob 41 is manually rotated using a tool such as a screwdriver. When the bolt knob 41 is rotated, the rough polishing sheet 42 moves downward under the action of the thread and separates from the polishing block 4, as shown in FIG. Figure 6As shown, the coarse grinding sheet 42 has a number of grooves, which can fully grind the old paint layer, rust, etc. on the surface of the door shell. At this time, the door shell surface is coarsely grinded by the coarse grinding sheet 42. When the grinding is completed and the surface needs to be finely grinded, the bolt knob 41 is manually reversed to reset the coarse grinding sheet 42, and the bottom surface of the grinding block 4 re-forms the completed grinding surface, and the door shell is finely grinded. By simply turning the bolt knob 41, the coarse grinding and fine grinding can be switched to improve the overall grinding efficiency.

[0044] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
