[0003] The existing protective structure of the manipulator can refer to the Chinese utility model patent with authorization announcement number CN221622268U, which discloses a safety protection structure for the manipulator, "including a support plate, a driving mechanism is provided inside the support plate, the inner wall of the support plate is slidably connected to a sliding block, one side of the sliding block is fixedly connected to a round rod, the outer surface of the round rod is slidably connected to the support plate, and the side of the round rod away from the sliding block is fixedly connected to the manipulator arm. The design structure of the utility model is reasonable. It can separate the inside and outside of the support plate by a dustproof cloth. When the dustproof cloth is away from the end of the support plate, the winding mechanism releases the dustproof cloth. When the dustproof cloth is close to the end of the support plate, the winding mechanism rolls up the dustproof cloth, thereby achieving comprehensive protection of the interior of the support plate when the manipulator moves, achieving the effect of preventing dust from entering, thereby solving the problem that dust easily enters the interior, thereby accelerating the wear of internal parts and affecting the service life of the manipulator."

[0004] When the above-mentioned device is in use, it adopts a driving mechanism to drive the mechanical arm to move by setting components such as a dustproof cloth and a winding mechanism, and separates the inside and outside of the support plate through the dustproof cloth, thereby preventing dust from entering the inside of the support plate. However, the above-mentioned device will cause gaps during use, which will cause debris generated by cutting to enter the inside of the device, affecting the operation of the device.

[0026] The driving device includes a servo motor 3 and a screw rod 4. When the servo motor 3 is working, it drives the screw rod 4 to rotate. The output shaft end of the servo motor 3 is bolted to one end of the screw rod 4. The inner cavity of the protective plate 1 is bolted to a bearing seat 5. The inner wall of the bearing seat 5 is rotatably connected to the outer wall of the end of the screw rod 4 away from the servo motor 3. The bottom of the inner cavity of the protective plate 1 is bolted to a slide rail 8, and a slide groove is provided at the position where the bottom of the slider 6 is connected to the slide rail 8. The top of the slide rail 8 is slidably connected to the inner wall of the slide groove provided at the bottom of the slider 6 to control the operation of the servo motor 3 and drive the screw rod 4 to rotate in the inner wall of the bearing seat 5. The slider 6 connected to the outer edge of the screw rod 4 is threaded, so that the screw rod 4 rotates and the slider 6 is driven to move at the same time. The use of the slide rail 8 in conjunction with the slider 6 can reduce the friction resistance and friction loss between the slider 6 and the protective plate 1 when moving, thereby improving the service life of the device and reducing the use cost of the device.

[0027] The protective device includes a waterproof curtain 9, which is shaped like an accordion and can be retracted. Waterproof curtains 9 are provided on the left and right outer walls of the slider 6. One end of the waterproof curtain 9 is fixed to the outer wall of the slider 6 by bolts, and the other end of the waterproof curtain 9 is fixed to the inner wall of the protective plate 1 by bolts. A limiting groove is provided at the position where the inner wall of the protective plate 1 is connected to the top and bottom of the waterproof curtain 9, and the inner wall of the limiting groove is slidably connected to the waterproof curtain 9. The accordion-shaped waterproof curtain 9 can retract with the movement of the slider 6 to protect the protective plate 1, prevent debris and cutting fluid generated by processing from entering the interior of the protective plate 1, and achieve comprehensive protection of the protective plate 1.

[0028] The interior of the protective plate 1 is a hollow structure. The output shaft end of the servo motor 3 is inserted into the interior of the protective plate 1, and the outer wall of the output shaft of the servo motor 3 is rotatably connected to the inner wall of the protective plate 1. The outer wall of the screw rod 4 is threadedly connected to the slider 6. The outer wall of the slider 6 is slidably connected to the inner cavity of the protective plate 1.

A sliding groove is provided at the position where the outer wall of the protective plate 1 is connected to the moving platform 7, and the inner wall of the sliding groove is slidably connected to the outer wall of the moving platform 7. The shape of the moving platform 7 is U-shaped, and a plurality of mounting holes are provided on the top of the moving platform 7. When the slider 6 moves, it drives the moving platform 7 fixed with the outer wall bolts to move on the top of the protective plate 1, thereby realizing the position adjustment of the manipulator.

[0029] Working principle: When in use, the servo motor 3 is controlled to work, driving the screw 4 to rotate in the inner wall of the bearing seat 5, and the slider 6 connected to the outer edge of the screw 4 is used to make the screw 4 rotate while driving the slider 6 to move, and drive the moving platform 7 fixed with the outer wall bolts to move on the top of the protective plate 1, and then use the waterproof curtain 9 fixed with the outer wall bolts on both sides of the slider 6 to make the slider 6 drive the waterproof curtain 9 on both sides to move and retract when moving. The waterproof curtain 9 can protect the slide groove opened on the outer wall of the protective plate 1 to prevent debris generated during the workpiece processing from entering the inside of the protective plate 1, and can also perform waterproof treatment on the protective plate 1 to prevent cutting fluid from entering the inside of the protective plate 1, thereby improving the protection effect of the device.
