Description

Technical Field

[0001] This application belongs to the field of lens inspection tool manufacturing technology, specifically an arc-shaped moving drive. Background Technology

[0002] When inspecting a lens, the points on the lens to be inspected need to be measured from multiple angles. This means taking values ​​at different angles of light illuminating the points on the lens to obtain comprehensive data. For example, measurements might be taken at an incident angle of 30°, 60°, 80°, and so on. Changing the incident angle of light illuminating the lens involves designing an arc-shaped guide rail, with the light source sliding between its two ends. The lens to be inspected is placed at the center of the arc-shaped guide rail. However, there is no standard thickness for the guide rail, and the radius of the arc-shaped guide rail varies depending on the size of the lens and the environment. Changing the radius and thickness of the guide rail requires a suitable light source to slide between its two ends, which is cumbersome and costly. Therefore, a light source that can adapt to guide rails of different radii and thicknesses is needed. Utility Model Content

[0003] The purpose of this application is to address the shortcomings of existing technologies by designing an arc-shaped motion driver that uses a chain, a guide rail gripper, and a servo motor with a sprocket to work together. This allows the same light source to slide on guide rails with different radii and thicknesses, thus solving the problem of how to drive the same light source to slide on guide rails with different radii and thicknesses.

[0004] To achieve the above objectives, the technical solution adopted in this application is:

[0005] An arc-shaped motion driver includes a base and a guide rail. The base is provided with a guide rail holder and a servo motor. A chain is provided on the guide rail. A sprocket that meshes with the chain is coaxially fixed on the output shaft of the servo motor.

[0011] Preferably, the connecting line segment between the sprocket and the roller is perpendicular to the upper surface of the base.

[0012] Preferably, the support leg is a telescopic structure.

[0013] Preferably, the support leg includes a mother rod and a daughter rod. The mother rod is a cylindrical shape with one end open. One end of the daughter rod is inserted into the mother rod and axially slidably connected to the mother rod. The side wall of the mother rod is provided with a threaded through hole.

[0024] like Figures 1-4 As shown, an arc-shaped moving drive includes a base 1 and a guide rail 14. The base 1 is provided with a guide rail holder and a servo motor 3. The guide rail 14 is provided with a chain 2. The output shaft of the servo motor 3 is coaxially fixed with a sprocket 4 that meshes with the chain 2. The base 1 is mounted on the guide rail 14 through the guide rail holder, and the base 1 can slide along the arc direction of the guide rail 14.

[0025] In this embodiment, during use, the chain 2 is fixed to the inner or outer arc-shaped surface of the guide rail 14, and the sprocket 4 controlled by the servo motor 3 is able to mesh with the chain 2. Finally, the seat 1 is fixed to the guide rail 14 by the guide rail holder, ensuring that the seat 1 will not fall off the guide rail 14 and will not restrict the seat 1 from sliding along the arc direction of the guide rail 14. Then, the light source is installed on the seat 1. When encountering guide rails 14 with different radii, since the chain 2 is flexible, it can always ensure that the seat 1 can slide between the two ends of the guide rail 14 under the drive of the servo motor 3. Then, different incident angles are obtained by the different positions of the seat 1 on the guide rail 14.

[0026] In a preferred embodiment, the guide rail holder includes a roller 5, and the base 1 is provided with a support leg 6. The roller 5 is mounted on the free end of the support leg 6. The axle of the roller 5 is parallel to the axle of the sprocket 4, and a predetermined distance is maintained between the projection of the sprocket 4 onto the length line of the support leg 6 and the projection of the roller 5 onto the length line of the support leg 6. With this configuration, the circumferential surface of the roller 5 and the sprocket 4 form a clamping device that holds the guide rail 14, thereby preventing the base 1 from falling off the guide rail 14.

[0027] As a preferred method, such as Figure 2As shown, the distance from the side of the roller 5 facing the seat 1 to the seat 1 is greater than the distance from the side of the sprocket 4 facing away from the seat 1 to the seat 1.

[0028] or

[0029] The distance from the side of the roller 5 facing away from the seat 1 to the seat 1 is less than the distance from the side of the roller 5 facing the seat 1 to the seat 1.

[0030] As a preferred embodiment, the base 1 is symmetrically provided with legs 6 on opposite sides. Each of the two legs 6 has a roller 5 on its facing surface. The axles of both rollers 5 are perpendicular to the length line of the leg 6, and the projections of the two rollers 5 onto the length line of the leg 6 coincide. By using the legs 6 to mount the rollers 5, the rollers 5 and the sprocket 4 form a clamping device. Simultaneously, the sprocket 4 cooperates with the chain 2, and under the action of the servo motor 3, it can drive the light source mounted on the base 1 to move along the guide rail 14.

[0031] As a preferred embodiment, the connecting line segment between the sprocket 4 and the roller 5 is perpendicular to the upper surface of the base 1. With this configuration, the light source is mounted on the lower surface of the base 1 when inspecting the lens.

[0032] As a preferred embodiment, the support leg 6 is a telescopic structure. This telescopic structure allows adjustment of the distance between the roller 5 and the sprocket 4 (or chain 2), thus making this application applicable to guide rails of different thicknesses.

[0033] In a preferred embodiment, the support leg includes a female rod 7 and a male rod 8. The female rod 7 is a cylindrical shape with one open end. One end of the male rod 8 is inserted into the female rod 7 and axially slidably connected to it. The female rod 7 has a threaded through hole on its side wall. One end of a bolt 9 is screwed into the female rod 7 through the threaded through hole and abuts against the male rod 8. With this configuration, the distance between the roller 5 and the sprocket 4 (or chain 2) can be adjusted by changing the relationship between the female rod 7 and the male rod 8.

[0034] As a preferred method, such as Figure 4As shown, by setting several mounting plates 10, during installation, bolts 9 can be passed through the mounting holes of the mounting plates 10, and then the mounting plates 10 can be fixed on the guide rail 14 for the sprocket 4 to move. Several mounting plates 10 are arranged along the length of the chain 2. Compared with setting a single mounting plate 10, this method of setting several mounting plates 10 does not affect the formation of the chain 2 into an arc similar to the guide rail 14, which is convenient for bending the chain 2. The mounting plates 10 are provided with through holes for mounting bolts 9. The mounting plates 10 are set on the side wall A11 of the chain 2, and the side wall A11 is parallel to the axis of the chain hole 12 on the chain 2 that meshes with the teeth of the sprocket 4.

[0035] As a preferred embodiment, the chain 2 has flexible mounting strips 13 on its sidewalls along its length. The sidewalls of the flexible mounting strips 13 are parallel to the axis of the chain holes 12 on the chain 2 that mesh with the sprocket 4. This configuration allows the chain 2 to be directly mounted on the guide rail 14 using adhesive. Compared to using multiple mounting plates, this provides a more stable fixation of the chain 2 and facilitates disassembly. The flexible mounting strips 13 can be made of stainless steel (similar to the elasticity of a spring) or rubber, etc.

[0036] As a preferred embodiment, the two ends of the flexible mounting strip 13 are aligned with the two ends of the chain 2, and the length of the flexible mounting strip 13 is equal to the length of the chain 2. This configuration allows the servo motor 3 to drive the base 1 from one end of the guide rail 14 to the other end of the guide rail 14.
