The bottom surface of the upper movable plate 7 is fixed with a sliding seat 24 corresponding to the vertical guide rails 8 one by one, and the sliding seat 24 slides in the vertical guide rails 8.

[0042] The beneficial effects of this embodiment are: vertical movement is achieved through the first guide rail 2, horizontal movement is achieved through the wedge plate 5 and the second guide rail 4, and the vertical guide rail 8 provides guidance, thereby improving movement accuracy, increasing stability, and having a compact structure.

[0043] Specifically, such as Figure 2 As shown, this motion module is mainly used in vertical installation working scenarios. When vertical movement is required, the middle plate 3 slides on the first guide rail 2, driving the wedge plate 5 and the upper motion plate 7 to move up and down;

[0044] When horizontal movement is required, the wedge plate 5 slides on the second guide rail 4, and the side of the upper moving plate 7 facing the wedge plate 5 is also an inclined surface. The inclined surface of the wedge plate 5 fits with the upper moving plate 7, slowly pushing the upper moving plate 7, and the upper moving plate 7 is guided by the vertical guide rail 8 to achieve horizontal movement.

[0049] Specifically, the first threaded screw 10 includes a first screw and a first nut. When the first motor 11 drives the first screw to rotate, the first nut moves linearly along the axis of the first screw, and the first nut drives the intermediate plate 3 to move linearly.

When the second motor 15 drives the second screw to rotate, the second nut moves linearly along the axis of the second screw. The second nut drives the wedge plate 5 to move linearly. The wedge plate 5 has an inclined surface and slowly lifts the upper moving plate 7.

[0056] In addition, the second threaded screw 14 and the first threaded screw 10 are parallel to each other and staggered in space, thereby reducing the overall height of the module.
