Description

Technical Field

[0001] This utility model relates to detection technology, and more particularly to a detection device for optical lenses. Background Technology

[0002] The design and manufacturing of optical lenses require consideration of various optical principles and processes to ensure that they can perform optimally and effectively in specific optical systems. Before use, optical lenses need to be inspected for scratches on their surfaces to determine their qualification and avoid situations where scratches on their surfaces lead to reduced precision or unusability of the installed equipment. During scratch inspection, the surface of the optical lens is illuminated and projected through a microscopic magnifying lens to determine the surface scratches.

[0003] Currently, when performing damage detection on the surface of optical lenses, only the horizontal plane is inspected, and rotation is not required. Therefore, damage in the deflection direction after the optical lens is rotated is often overlooked, resulting in a decrease in the yield rate. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] like Figures 1 to 7 As shown, this optical lens testing device includes a worktable 1 and a holding assembly 2. The worktable 1 is equipped with a controller 3, a lifting mechanism 4, an illumination light source 5, and a display screen 6. A camera is also installed inside the illumination light source 5 to capture the status information of the lower optical lens 7 and transmit it to the display screen 6 for recording and analysis. Simultaneously, a light source can also be installed inside the worktable 1 to facilitate illumination of the optical lens 7. The lifting mechanism 4 is used to change the position of the illumination light source 5, which can move left and right and back and forth on the lifting mechanism 4.

[0023] The retaining component 2 is mounted on the worktable 1 via a mounting block 8. The retaining component 2 includes a retaining element 9 and a positioning element 10. The retaining component 2 is used to limit the position of the positioning element 10 and maintain the preload between the positioning element 10 and the retaining element 9, so that the angle does not change after the limit is reached.

[0024] The retainer 9 is bolted to the mounting block 8, and the retainer 9 has a mounting part 91 that mates with the mounting block 8. A clamping area 12 is formed in the middle of the retainer 9, and multiple pre-tightening members 11 are provided on the retainer 9. The pre-tightening members 11 can be bolts. The pre-tightening members 11 are used to maintain the size of the clamping area 12, so that the distance between the upper retaining piece 13 and the lower retaining piece 14 is reduced or increased, thereby clamping the ball 17 through the upper elastic part 15 and the lower elastic part 16.

[0025] Furthermore, since the sphere 17 is made of rubber, when the distance between the upper elastic part 15 and the lower elastic part 16 decreases, the force between the upper elastic part 15 and the lower elastic part 16 can increase, thereby clamping the sphere 17 and preventing the sphere 17 from rotating easily within the elastic region 18. The sphere 17 can only rotate when subjected to a large external force or when the distance between the clamping regions 12 increases.

[0026] The two ends of the positioning member 10 are set in the clamping area 12, and the middle of the positioning member 10 forms a positioning area 19 for accommodating the optical lens 7. Rotating the positioning member 10 keeps the positioning member 10 rotating in the middle of the holding member 9, thereby changing the angle of the optical lens 7.

[0027] The retaining member 9 consists of an upper retaining plate 13, a lower retaining plate 14, and an arc-shaped portion 20. The upper retaining plate 13 and the lower retaining plate 14 are connected by the arc-shaped portion 20, and a clamping area 12 is formed between the upper retaining plate 13 and the lower retaining plate 14. An active area 21 for accommodating the rotation of the positioning member 10 is formed in the middle of the retaining member 9. The upper retaining plate 13 and the lower retaining plate 14 are in the shape of a "door", with one end open to form the active area 21.

[0028] The upper retaining plate 13 has an upper punching hole 22, and the lower retaining plate 14 has a lower punching hole 23. An upper elastic portion 15 is provided within the upper punching hole 22, and a lower elastic portion 16 is provided within the lower punching hole 23. The upper elastic portion 15 and the lower elastic portion 16 have opposite inclination angles, such that their movable ends face each other. Both the upper elastic portion 15 and the lower elastic portion 16 have spherical surfaces 24, and spherical grooves 25 are provided on the spherical surfaces 24. An elastic region 18 is formed between the upper elastic portion 15 and the lower elastic portion 16.

[0029] The positioning component 10 consists of a frame 26, symmetrically arranged connecting rods 27, and a ball 17. The ball 17 is located within an elastic region 18. A positioning region 19 is formed in the middle of the frame 26, and an edge support 28 is provided within the positioning region 19. A notch 29 is provided on the frame 26 to facilitate the removal of the optical lens 7 located in the positioning region 19. Because the notch 29 is located at the edge of the frame 26, it prevents the surface of the optical lens 7 from becoming contaminated.

[0030] When in use, place the optical lens 7 to be tested directly in the positioning area 19 of the positioning member 10, and then rotate the positioning member 10 as needed. You can also rotate while testing, or rotate the pre-tightening member 11 to keep the positioning member 10 in a fixed position angle and keep its position unchanged.

[0031] The actual use of the detection device in this application can refer to the prior art. The main structure protected by this application is the positioning and angle adjustment structure of the optical lens 7. The other structures can refer to the existing technology structures, so they will not be described in detail here.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
