Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to an optical lens bonding clamp. Background Technology

[0002] Optical lens bonding is a common process in the manufacture of optical components. It is mainly used to bond multiple lenses together with optical adhesive to form a composite optical element, which can significantly improve the performance and reliability of optical systems and is widely used in microscopes, camera lenses, telescopes, laser systems and other fields.

[0003] Research revealed that existing optical lens clamps have certain problems. During the bonding process, dust in the air can easily adhere to the bonding surface of the optical lens, which can lead to impurities inside the bonded optical lens. Therefore, there is a need for an optical lens bonding clamp to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide an optical lens bonding clamp to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an optical lens bonding clamp, comprising a base, a lower clamp on the base, a lower pad flexibly connected inside the lower clamp, a bracket on the base, a screw threaded to the top of the bracket, a movable block movably connected to the bottom of the screw, a first spring connected to the bottom of the movable block, an upper clamp on the bottom of the first spring, a sliding insert rod slidably fitted inside the upper clamp, the insert rod connected to the bottom of the movable block, an upper pad connected to the bottom of the insert rod, the upper pad being arranged inside the upper clamp, a turntable rotatably connected to the bottom of the upper clamp, a slot on the turntable, and a lint-free cloth and gauze on both the top and bottom of the turntable, the slot, lint-free cloth, and gauze corresponding to the inner cavities of the upper and lower clamps.

[0006] Preferably, the lower clamp and the lower pad are flexibly connected by a second spring.

[0007] Preferably, a support shaft is provided at the bottom end of the screw, the support shaft has a T-shaped cross-section, and the support shaft is rotatably connected to the top end of the moving block.

[0008] Preferably, the bracket is L-shaped, with vertically arranged guide grooves on the vertical frame, and guide blocks are slidably connected in the guide grooves, with the guide blocks connected to the outer wall of the moving block.

[0009] Preferably, the outer diameter of the upper pad is larger than the outer diameter of the insertion rod.

[0010] Preferably, a positioning shaft is provided at the bottom end of the upper clamp, the positioning shaft has a T-shaped cross-section, and the turntable is rotatably connected to the positioning shaft.

[0011] Preferably, the turntable is movably connected with a number of ball bearings, which are evenly distributed in a circumferential open ring, and each ball bearing can contact the top end of the lower clamp and the bottom end of the upper clamp.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, the rotation of the turntable, along with the cooperation between the slot, the lint-free cloth, and the gauze, allows the optical lens to be installed within the upper clamp when the slot aligns with the inner cavity of the upper clamp. The lint-free cloth's alignment with the upper clamp's inner cavity prevents the optical lens from falling out. Simultaneously, the turntable's rotation creates friction between the lint-free cloth and the optical lens, wiping the adhesive surface of the lens. When the gauze aligns with the upper clamp, the UV-curing adhesive applied to the gauze is evenly spread onto the adhesive surface of the optical lens, effectively ensuring the cleanliness of the lens's bonding surface and the uniformity of the adhesive application.

[0014] In this invention, the rotation of the screw lowers the moving block, which, connected by the first spring, causes the upper clamp to descend, gradually moving closer to the lower clamp and pressing the turntable in the middle. Rotating the turntable allows for simultaneous wiping and application of UV-curing adhesive to the upper and lower optical lenses. Further rotation of the turntable aligns the slots with the upper and lower clamps, completing the contact and pressing of the two optical lenses, thus achieving the bonding process. Compared to existing technologies, this invention effectively prevents contact between the optical lenses and external dust during bonding, improving the bonding quality. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 An optical lens bonding clamp includes a base 1, a lower clamp 2 on the base 1, a lower pad 3 flexibly connected inside the lower clamp 2, a bracket 4 on the base 1, a screw 5 internally threaded to the top of the bracket 4, a movable block 6 movably connected to the bottom of the screw 5, a first spring 7 connected to the bottom of the movable block 6, an upper clamp 8 on the bottom of the first spring 7, a sliding insert 9 slidably fitted inside the upper clamp 8, the insert 9 connected to the bottom of the movable block 6, an upper pad 10 connected to the bottom of the insert 9, the upper pad 10 arranged inside the upper clamp 8, a turntable 11 rotatably connected to the bottom of the upper clamp 8, a slot 12 opened on the turntable 11, a clean cloth 13 and gauze 14 on both the top and bottom of the turntable 11, the slot 12, the clean cloth 13 and the gauze 14 can all correspond to the inner cavity positions of the upper clamp 8 and the lower clamp 2.

[0022] The rotation of the turntable 11, along with the interaction between the slot 12, the lint-free cloth 13, and the gauze 14, allows the optical lens to be installed within the upper clamp 8 when the slot 12 aligns with its inner cavity. The lint-free cloth 13, when aligned with the inner cavity of the upper clamp 8, prevents the optical lens from falling out. Simultaneously, the rotation of the turntable 11 creates friction between the lint-free cloth 13 and the optical lens, wiping the adhesive surface of the lens. When the gauze 14 aligns with the upper clamp 8, the UV-curing adhesive applied to it is evenly spread across the adhesive surface of the optical lens, effectively ensuring the cleanliness of the lens bonding surface and the proper application of adhesive. The uniform effect is achieved by rotating the screw 5, which lowers the moving block 6. The upper clamp 8 is lowered via the connection of the first spring 7, causing the upper clamp 8 to gradually approach the lower clamp 2 and press the turntable 11 in the middle. By rotating the turntable 11, the upper and lower optical lenses are wiped and UV-cured adhesive is applied simultaneously. By rotating the turntable 11, the slot 12 is aligned with the upper clamp 8 and the lower clamp 2, completing the contact and pressing of the upper and lower optical lenses, thus realizing the process of optical lens bonding. Compared with the existing technology, this method can effectively prevent the optical lenses from coming into contact with external dust during the bonding process, thus improving the bonding quality of the optical lenses.

[0023] Specifically, in this embodiment, the lower clamp 2 and the lower pad 3 are flexibly connected by a second spring 15. The elasticity of the second spring 15 facilitates the removal of the optical lens after it has been glued together.

[0024] Specifically, in this embodiment, a support shaft 16 is provided on the bottom end of the screw 5. The cross-section of the support shaft 16 is T-shaped. The support shaft 16 is rotatably connected to the top end of the moving block 6. The support shaft 16 makes the rotation of the screw 5 and the movement of the moving block 6 independent of each other, while facilitating the screw 5 to reverse and pull the moving block 6 upward.

[0025] Specifically, in this embodiment, the bracket 4 is L-shaped, and a vertically arranged guide groove 17 is provided on the vertical frame. A guide block 18 is slidably connected in the guide groove 17. The guide block 18 is connected to the outer wall of the moving block 6, restricting the rotation of the moving block 6, thereby ensuring that the moving block 6 performs stable lifting and pressing movements.

[0026] Specifically, in this embodiment, the outer diameter of the upper pad 10 is larger than the outer diameter of the insertion rod 9, providing a bottom limit for the upper clamp 8 to prevent it from falling.

[0027] Specifically, in this embodiment, a positioning shaft 19 is provided on the bottom end of the upper clamp 8. The cross-section of the positioning shaft 19 is T-shaped. The turntable 11 is rotatably connected to the positioning shaft 19, providing a stable rotation fulcrum for the turntable 11 and preventing it from separating from the upper clamp 8.

[0028] Specifically, in this embodiment, a number of ball bearings 20 are movably connected inside the turntable 11. The ball bearings 20 are evenly distributed in a circumferential open ring. All the ball bearings 20 can contact the top end of the lower clamp 2 and the bottom end of the upper clamp 8, thereby improving the smoothness of the turntable 11 rotation after the upper clamp 8 and the lower clamp 2 are pressed together.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
