[0048] Those skilled in the art should understand that the drawings are merely schematic diagrams of embodiments, and the components in the drawings are not necessarily necessary for implementing the present invention.

[0049] like Figures 1 to 15 As shown, in this embodiment, a motion mechanism shielding shield is provided, comprising: a fixed shield 1; a guide shield 2 is connected to one end of the fixed shield 1; a base 3 is detachably connected to the fixed shield 1; a first linear feed device 4 is provided at one end of the base 3; a second linear feed device 5 is provided on the first linear feed device 4; a connecting shaft 6 is provided on the second linear feed device 5, and a motion shield 7 is detachably connected to the connecting shaft 6. Figure 1 、 Figure 3 As shown, specifically, a limiting through hole 9 is provided on the moving shield 7, the length direction of the limiting through hole 9 is consistent with the width direction of the base 3, and the width direction of the limiting through hole 9 matches the diameter of the connecting shaft 6; an oblique opening 10 for inserting the connecting shaft 6 into the limiting through hole 9 is provided on one side of the moving shield 7, and the connecting shaft 6 can be inserted into the limiting through hole 9 by separating the oblique opening 10. Among them, the first linear feed device 4 can drive the second linear feed device 5 to reciprocate in the length direction of the base 3, and the second linear feed device 5 can drive the connecting shaft 6 to reciprocate in the width direction of the base 3; the guide shield 2 is provided with a guide groove 8 for the moving shield 7 to be inserted. When the first linear feed device 4 drives the second linear feed device 5 to reciprocate in the length direction of the base 3, the second linear feed device 5 drives the connecting shaft 6 to reciprocate in the length direction of the base 3. Further, the connecting shaft 6 drives the moving shield 7 to reciprocate along the guide groove 8. The second linear feed device 5 can drive the connecting shaft 6 to reciprocate in the width direction of the base 3. Since the length direction of the limiting through hole 9 is consistent with the width direction of the base 3, when the connecting shaft 6 reciprocates in the width direction of the base 3, it will not drive the moving shield 7 to reciprocate in the width direction of the base 3.

[0050] In order to realize the detachable connection between the base 3 and the fixed shield 1, connecting clamps 11 are provided on both sides of the base 3, and multiple groups of wing groups are provided on the connecting clamps 11, each wing group includes two opposite wing groups 12, and a bayonet 13 is provided between the two opposite wings 12; multiple clamping columns 14 are provided on both sides of the fixed shield 1, and each clamping column 14 corresponds to a group of wing groups, and the bayonet 13 is clamped on the clamping column 14 to realize the detachable connection between the base 3 and the fixed shield 1.

[0051] The first linear feed device 4 includes a fixed base 15 connected between two sides of the base 3. A first drive screw is provided on one side of the fixed base 15. The first drive screw is connected to a first slide 16 that can slide on the fixed base 15. The first drive screw includes a first drive mechanism 23 provided on the fixed base 15. The first drive mechanism 23 is connected to a first screw 24. A first slider 25 is slidably connected to the first screw 24. The first slider 25 is connected to the first slide 16. The fixed base 15 is provided with a first slide rail 29. The first slide 16 is provided with a first slide groove that matches the first slide rail 29. The first slide 16 slides on the fixed base 15 along the first slide rail 29. Specifically, the first lead screw 24 is provided with an external thread, and the first slider 25 is provided with a through hole with an internal thread. The first lead screw 24 passes through the through hole and is threadedly connected to the first slider 25. When the first driving mechanism 23 drives the first lead screw 24 to rotate, the first slider 25 moves on the first lead screw 24, thereby driving the first slide 16 to slide on the fixed seat 15 along the first slide rail 29.

[0052] Similarly, the second linear feed device 5 includes a second drive screw connected to the first slide 16. The second drive screw is connected to a second slide 17 that can slide on the first slide 16. The second slide 17 is provided with the connecting shaft 6. The second drive screw includes a second drive mechanism 26 provided on the first slide 16. The second drive mechanism 26 is connected to a second screw 27. The second screw 27 is slidably connected to a second slider 28. The second slider 28 is connected to the second slide 17. The first slide 16 is provided with a second slide rail 30. The second slide 17 is provided with a second slide groove that matches the second slide rail 30. The second slide 17 slides on the first slide 16 along the second slide rail 30. Specifically, the second lead screw 27 is provided with an external thread, and the second slider 28 is provided with a through hole with an internal thread. The second lead screw 27 passes through the through hole and is threadedly connected to the second slider 28. When the second driving mechanism 26 drives the second lead screw 27 to rotate, the second slider 28 moves on the second lead screw 27, thereby driving the second slide 17 to slide on the first slide 16 along the second slide rail 30.

[0053] The fixing base 15 is provided with a first through hole 18, the first slide 16 is provided with a second through hole 19, the base 3 is provided with a first opening 20, and the fixing shield 1 and the guide shield 2 are provided with corresponding second openings 21. The connecting shaft 6 extends through the first through hole 18, the second through hole 19, the first opening 20, and the second opening 21 and is connected to a connecting member 22. The disc-shaped connecting member 22 is used to connect to other mechanisms.

[0054] In a specific embodiment, both the first driving mechanism 23 and the second driving mechanism 26 can be servo motors.

[0055] like Figure 1 、 Figure 2 As shown, the base 5 can be regarded as an XY motion platform, the second linear feed device is a Y motion platform, the first linear feed device is an X motion platform, and the second drive screw is a Y motion drive device, which realizes the movement of the second slide in the Y direction. The first linear feed device is an X motion drive device, which realizes the movement of the first slide in the X direction.

[0056] like Figure 4 As shown, under the combined action of the first and second linear feed devices, the center of the connecting shaft moves along a trajectory within the rectangular dashed area in the figure. The connecting shaft moves within a certain range in the X and Y directions, forming a moving exposed portion. The shielding shield described in this embodiment shields this moving exposed portion.

[0057] like Figure 7 、 Figure 8 As shown, when installing the sports shield, the oblique opening 10 relies on its own deformation during installation to open the sports shield from the oblique opening 10 and sleeve it on the connecting shaft. With this installation method, the sports shield can be installed and removed without removing the connecting piece 22. Figure 9 、 Figure 10 As shown, after the moving shield is installed, the fixed shield is installed, the moving shield is installed under the fixed shield, and the fixed shield is connected to the base through the connecting card.

[0058] like Figure 11 As shown, the guide shields are arranged on both sides of the guide shield. Figure 12 、 Figure 13 As shown, install the guide shield on Figure 10 In the state shown, insert the moving guard into the guide grooves on both sides. The guide guard is the same as the fixed guard, with clamping posts on both sides corresponding to the bayonet holes on the connecting card. After the moving guard is installed in place, the guide guard is fixed to the connecting card through the bayonet holes and the clamping posts. Figure 14As shown. After installation, when the connecting shaft moves in the Y direction, the shaft moves in the oblong groove (limiting hole 9) on the motion shield, and the motion shield remains stationary. When the connecting shaft moves in the X direction, the movement of the connecting shaft pushes the motion shield to move with it. The motion shield moves back and forth linearly guided by the guide groove, achieving the overall motion shielding effect.

[0059] like Figure 15 As shown, the mounting opening (oblique mounting opening 10) on the moving shield is inclined, tilted toward the guide shield; when the moving shield moves repeatedly in the X direction, the guide groove on the guide shield is always ensured to press on the mounting opening, ensuring that there is no scratching, abnormal noise or warping of the opening to cause movement interference during the movement process.

[0060] Although the above describes the specific implementation methods of the present invention in conjunction with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution disclosed in the present invention, various modifications or variations that can be made by technical personnel in this field without creative work should be included in the scope of protection of the present invention.
