[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: Figure 1 - Figure 4 As shown, the utility model provides a linear module with an anti-foreign matter structure, including a linear module mechanism 1, an outer wall of the linear module mechanism 1 is provided with a protective mechanism 2, and the linear module mechanism 1 includes a protective box 11 and a special-shaped connecting plate 14;

[0023] The protective mechanism 2 includes multiple groups of guide wheels 23. Two groups of square grooves 21 are provided on the outer wall of the protective box 11. The interior of the two groups of square grooves 21 is provided with special-shaped flexible plates 22. The two end faces of the two groups of special-shaped flexible plates 22 are respectively fixed to the two ends of the two protrusions at the lower end of the special-shaped connecting plate 14. Storage grooves 24 are provided at both ends and the lower end face of the square grooves 21. Rotating holes 25 are provided on both side walls of the multiple groups of storage grooves 24. Rotating rods 26 are welded on both sides of the multiple groups of guide wheels 23. The outer walls of the multiple groups of guide wheels 23 are respectively in contact with the inner walls of the two groups of special-shaped flexible plates 22. The multiple groups of guide wheels 23 are respectively arranged inside the multiple groups of storage grooves 24, and the multiple groups of rotating rods 26 are respectively rotatably installed inside the rotating holes 25.

[0024] The following is a detailed description of the specific settings and functions of this embodiment. Two sets of square grooves 21 are opened on the outer wall of the protective box 11, and the two sets of square grooves 21 are flush with the two sets of guide holes 13 respectively, and special-shaped flexible plates 22 are sleeved inside the two sets of square grooves 21. The two ends of the two sets of special-shaped flexible plates 22 are respectively fixed to the two ends of the two protrusions at the lower end of the special-shaped connecting plate 14. At this time, the two sets of special-shaped flexible plates 22 will respectively block the two sets of guide holes 13, and then the opening of the protective box 11 can be sealed, thereby preventing dust, iron filings and other foreign matter from easily entering the module, preventing wear on the lead screw 15 and the threaded seat 16 inside the protective box 11, and increasing the service life of the linear module mechanism 1;

[0025] When the special-shaped connecting plate 14 moves left and right, the special-shaped connecting plate 14 drives the two groups of special-shaped flexible plates 22 to move left and right together through the two protrusions at the lower end, so that the two groups of special-shaped flexible plates 22 move respectively inside the two groups of square grooves 21. At the same time, the inner walls of the two groups of special-shaped flexible plates 22 respectively generate friction with the multiple groups of guide wheels 23, and drive the multiple groups of guide wheels 23 to rotate inside the multiple groups of storage slots 24. At the same time, the multiple groups of guide wheels 23 will drive the multiple groups of rotating rods 26 to rotate, and the multiple groups of rotating rods 26 respectively rotate inside the multiple groups of rotating holes 25, thereby guiding the two groups of special-shaped flexible plates 22, thereby reducing the friction between the two groups of special-shaped flexible plates 22 and the two groups of square grooves 21, increasing the service life of the two groups of special-shaped flexible plates 22, and at the same time, improving the smoothness of the movement of the two groups of special-shaped flexible plates 22.

[0026] Example 2: Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the linear module mechanism 1 includes a protective box 11 and a special-shaped connecting plate 14. A stepper motor 12 is fixedly installed at one end of the protective box 11. Two groups of guide holes 13 are opened through the upper end of the protective box 11. A lead screw 15 is rotatably installed inside the protective box 11. The outer wall of the lead screw 15 is threadedly connected to a threaded seat 16. The threaded seat 16 is slidably installed inside the protective box 11. One end of the lead screw 15 passes through one end of the protective box 11 and is fixed to the output end of the stepper motor 12. The two protrusions at the lower end of the special-shaped connecting plate 14 pass through the interior of the two groups of guide holes 13 respectively and are fixed to the upper end of the threaded seat 16.

[0027] The effect achieved by the entire embodiment is that by starting the stepper motor 12, the output end of the stepper motor 12 drives the lead screw 15 to rotate, and the lead screw 15 rotates on the internal thread of the threaded seat 16. Since the threaded seat 16 is slidably installed inside the protective box 11, the threaded seat 16 can only move left and right along the outer wall of the lead screw 15, and the threaded seat 16 will move left and right inside the protective box 11. At the same time, the threaded seat 16 will also drive the special-shaped connecting plate 14 to move. The two protrusions of the special-shaped connecting plate 14 slide inside the two groups of guide holes 13 respectively, and then drive the special-shaped connecting plate 14 to move, so as to maintain stable movement, ensure that each movement can accurately reach the predetermined position, and ensure the consistency and stability of product quality.

[0028] The method of use and working principle of this device: First, assemble the device with the matching device, start the stepper motor 12, and the output end of the stepper motor 12 drives the screw 15 to rotate. The screw 15 rotates on the internal thread of the threaded seat 16, and the threaded seat 16 moves left and right inside the protective box 11. At the same time, the threaded seat 16 also drives the special-shaped connecting plate 14 to move. The two protrusions of the special-shaped connecting plate 14 slide inside the two groups of guide holes 13 respectively, and then drive the special-shaped connecting plate 14 to move, which can maintain stable movement. Finally, when the special-shaped connecting plate 14 moves left and right, the special-shaped connecting plate 14 will drive the two groups of special-shaped flexible plates 22 to move left and right together. The right movement causes the two groups of special-shaped flexible plates 22 to move inside the two groups of square grooves 21 respectively. At the same time, the inner walls of the two groups of special-shaped flexible plates 22 respectively generate friction with the multiple groups of guide wheels 23, and drive the multiple groups of guide wheels 23 to rotate inside the multiple groups of storage slots 24. At the same time, the multiple groups of guide wheels 23 will drive the multiple groups of rotating rods 26 to rotate, and the multiple groups of rotating rods 26 respectively rotate inside the multiple groups of rotating holes 25, which can guide the two groups of special-shaped flexible plates 22, reduce the friction between the two groups of special-shaped flexible plates 22 and the two groups of square grooves 21, increase the service life of the two groups of special-shaped flexible plates 22, and at the same time, improve the smoothness of the movement of the two groups of special-shaped flexible plates 22.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
