Description

Technical Field

[0001] This utility model relates to the field of grinding machine loading technology, and more specifically, to an automatic loading and unloading mechanism for a surface grinder. Background Technology

[0002] A surface grinder is a mechanical device used to process flat surfaces. It is mainly used for surface grinding, lapping and polishing of workpieces. The surface grinder applies pressure to the surface of the workpiece by grinding stones or grinding wheels and grinds in a rotating manner, thereby achieving precise finishing and processing of the workpiece surface.

[0003] Currently, some existing surface grinders lack automatic loading and unloading mechanisms, requiring manual loading and unloading of workpieces during grinding. This is especially true for thin sheet workpieces, which require frequent loading and unloading due to the short grinding time, thus increasing the labor intensity of workers. The low level of automation also affects work efficiency. Therefore, we provide an automatic loading and unloading mechanism for surface grinders. Utility Model Content

[0020] 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.

[0021] Please see Figures 1 to 4 An automatic loading and unloading mechanism for a surface grinder includes a worktable 1. A first mounting plate 2 is fixedly connected to the top of the worktable 1. A rotating shaft 3 is rotatably connected inside the first mounting plate 2. A first swing plate 4 is fixedly connected to one end of the rotating shaft 3. A movable frame 5 is rotatably connected to the outer side of the first swing plate 4 away from the rotating shaft 3. A second swing plate 6 is rotatably connected to the outer side of the movable frame 5 away from the first swing plate 4. The first swing plate 4 and the second swing plate 6 drive the movable frame 5 to move back and forth, cooperating with a vacuum suction cup 10 to achieve automatic loading and unloading. The second swing plate 6 is rotatably connected to the first mounting plate 2. A sliding groove 7 is opened inside the movable frame 5. A slider 8 is slidably connected inside the sliding groove 7. An electric telescopic rod 9 is fixedly connected to the bottom of the slider 8. A vacuum suction cup 10 is fixedly connected to the output end of the electric telescopic rod 9. The height of the vacuum suction cup 10 can be adjusted by the electric telescopic rod 9, and the vacuum suction cup 10 can grip the workpiece.

[0022] Furthermore, the first swing plate 4 and the second swing plate 6 have the same specifications. The first swing plate 4 and the second swing plate 6 are connected by the movable frame 5 to form a parallelogram mechanism, which ensures that the movable frame 5 maintains a horizontal posture during the swing process, which is conducive to the stable gripping of the workpiece.

[0023] Furthermore, a first servo motor 11 is fixedly connected to the outside of the movable frame 5. The output shaft of the first servo motor 11 passes vertically through the movable frame 5 and extends into the interior of the slide groove 7. The output shaft of the first servo motor 11 is rotatably connected to the movable frame 5. A lead screw 12 is fixedly connected to the output end of the first servo motor 11. The lead screw 12 passes vertically through the slider 8 and extends to the other side of the slider 8. The lead screw 12 is rotatably connected to the movable frame 5. The slider 8 is threadedly connected to the lead screw 12. The first servo motor 11 drives the lead screw 12 to rotate, so that the lead screw 12 drives the slider 8 to move in the slide groove 7. When the slider 8 moves, the position of the electric telescopic rod 9 and the vacuum suction cup 10 can be adjusted.

[0024] Furthermore, the outer wall of the slider 8 fits against the inner wall of the groove 7, and the slider 8 and the groove 7 fit tightly together, which can limit the slider 8 so that the slider 8 can only slide back and forth within the groove 7.

[0025] Furthermore, a second mounting plate 13 is fixedly connected to the top of the workbench 1. A second servo motor 14 is fixedly connected to one side of the second mounting plate 13. The output shaft of the second servo motor 14 passes vertically through the second mounting plate 13 and extends to the other side of the second mounting plate 13. The output shaft of the second servo motor 14 is rotatably connected to the second mounting plate 13. A rotating plate 15 is fixedly connected to the output end of the second servo motor 14. A third swing plate 16 is fixedly connected to the outer end of the rotating shaft 3 away from the first swing plate 4. A connecting plate 17 is provided between the third swing plate 16 and the rotating plate 15. One end of the connecting plate 17 is rotatably connected to the third swing plate 16, and the other end of the connecting plate 17 is rotatably connected to the rotating plate 15. The second servo motor 14 directly drives the rotating plate 15 to rotate. The rotating plate 15 then drives the third swing plate 16 to swing back and forth through the connecting plate 17. The third swing plate 16 drives the rotating shaft 3 to twist back and forth. Finally, the rotating shaft 3 drives the first swing plate 4 to swing back and forth, which in turn drives the movable frame 5 to swing back and forth in conjunction with the second swing plate 6.

[0026] Furthermore, the second mounting plate 13 is externally fixedly connected to a control panel 18. The electric telescopic rod 9, vacuum suction cup 10, first servo motor 11, and second servo motor 14 are all electrically connected to the control panel 18. Through electrical connections such as cables and buses, various actuators are integrated together. Operators only need to use one control panel 18 to perform multiple operations such as telescopic control of the electric telescopic rod 9, suction and release of the vacuum suction cup 10, and speed and direction adjustment of the first servo motor 11 and second servo motor 14. There is no need to control different components separately, which can improve operating efficiency.

[0027] The usage steps of this utility model are as follows: When the automatic loading and unloading mechanism of this surface grinder is in use, after the equipment is turned on, the control panel 18 performs a self-check, and each component returns to its initial position. The second servo motor 14 drives the rotating plate 15 to rotate. The rotating plate 15, the connecting plate 17, and the third swing plate 16 form a linkage mechanism. When the rotating plate 15 rotates, it drives the third swing plate 16 to swing back and forth through the connecting plate 17. The third swing plate 16 then drives the first swing plate 4 to swing back and forth through the rotating shaft 3. The first swing plate 4, together with the second swing plate 6, drives the movable frame 5 to swing back and forth. The first swing plate 4 and the second swing plate 6 are connected through the movable frame 5 to form a parallelogram mechanism, ensuring that the movable frame 5 maintains a horizontal posture during the swing process, which is conducive to stable gripping of the workpiece. When the movable frame 5 moves above the workpiece, the vacuum suction cup 10 is activated, generating negative pressure to adsorb the workpiece, transporting the workpiece to the target position and putting it down, thus achieving the purpose of automatic loading and unloading. It has a high degree of automation, which can reduce the labor intensity of workers and improve work efficiency.

[0028] This design achieves precise movement of the vacuum suction cup in three-dimensional space through multi-motor coordinated control and linkage mechanism. It features a compact structure, flexible movement, and high positioning accuracy, making it suitable for material handling, assembly, and other operations in automated production lines.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
