Description

Technical Field

[0001] This utility model belongs to the field of optical lens processing technology, and in particular relates to an optical lens positioning device. Background Technology

[0002] In the process of optical lens processing, large optical lenses are usually fixed with adhesive and then cut into smaller pieces in batches using an inner circle cutting machine.

[0003] In existing technologies, fixtures for inner circle lens cutting often employ a two-plate structure: a shorter plate with threaded holes on one side and the other side used to bond the lens to be cut; one end of a longer plate is connected to the shorter plate via a screw, and the other end is fixed to the inner circle cutting machine. Once the lens is bonded and fixed to the shorter plate, the cutting direction is fixed. After cutting in one direction, the lens must be separated from the plate and re-bonded in the next direction before cutting in the next direction can proceed. This process is cumbersome, and repeated bonding can easily lead to 90-degree angle accuracy deviations, affecting product yield. If cutting lenses at different angles is required, angled supports are also needed for positioning and bonding. The accuracy of these supports and human error further reduce the fixing effect and angle accuracy. Summary of the Invention

[0004] The purpose of this invention is to provide an optical lens positioning device to solve the problems of uneven clamping force, difficult material distribution steps, and difficult parameter adjustment in common lifting clamping devices.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: it includes a base, one side of which is a flat part with a groove, and the other side of which is a connecting part for detachably installing and connecting with a cutting device; the connecting part includes a plurality of columnar fixing piles, which are distributed in a nine-square pattern on the surface of the base and fixedly connected.

[0006] Furthermore, each of the aforementioned fixed piles is provided with a threaded hole, and the fixed pile is fixedly connected to the base.

[0007] Furthermore, the connecting part also includes an integrated connecting cylinder and a clamping plate. The connecting cylinder is sleeved on the outside of one end of the fixed pile and is fastened by screws passing through it.

[0008] Furthermore, the clamping plate is disposed at the outermost end of the connecting cylinder, and the clamping plate is detachably connected to the cutting device.

[0009] Furthermore, the groove is shaped like a cross, located at the center of the planar portion and open at both ends, for the collection and flow of material debris.

[0010] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects: 1. In this utility model, through the design of the nine-square-shaped fixed piles and connecting parts, the lens positioning device can be connected to the cutting device in different positions, realizing multi-angle cutting of the lens without the need to remove the glue and re-attach, which significantly improves processing efficiency and angle accuracy. 2. In this utility model, the fixed pile is fixedly connected to the base, the connecting cylinder is fastened with screws to ensure overall rigidity, and the clamping plate and the cutting device are detachably connected, making installation simple and reducing manual adjustment errors; 3. In this utility model, the cross-shaped groove design facilitates the collection and flow of debris, preventing debris accumulation from affecting the lens fixing and cutting quality; 4. In this utility model solution, the distribution and connection method of the fixed piles can be customized as needed to adapt to the cutting requirements of different angle lenses, reduce dependence on the support body, and improve the yield rate.

[0013] 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.

[0014] Combination Figures 1 to 6 An optical lens positioning device is shown, including a base 1. One side of the base 1 is a flat part 3 with a groove 2, and the other side of the base 1 is a connecting part 4 for detachably connecting with a cutting device A. The connecting part 4 includes a plurality of columnar fixing posts 41, which are distributed in a nine-square pattern on the surface of the base 1 and fixedly connected.

[0015] Among them, several fixed piles 41 are provided with threaded holes 42, and the fixed piles 41 are fixedly connected to the base body 1.

[0016] The connecting part 4 also includes an integral connecting cylinder 43 and a clamping plate 44. The connecting cylinder 43 is sleeved on the outside of one end of the fixed pile 41 and is fastened by screws.

[0017] The clamping plate 44 is located at the outermost end of the connecting cylinder 43, and the clamping plate 44 is detachably connected to the cutting device A.

[0018] The groove 2 is shaped like a cross, located at the center of the flat part 3 and connected at both ends, for the collection and flow of material debris.

[0019] Working Principle: In use, the optical lens is first bonded to the flat part 3. Then, according to the cutting angle requirements, the corresponding fixing post 41 of the connecting part 4 is selected, and the positioning device is installed on the cutting device A through the connecting cylinder 43 and the clamping plate 44. When cutting in the first direction, the clamping plate 44 is fixed to the groove plate of the cutting device A by clamping. After cutting in this direction, it is only necessary to loosen the connection and re-fix it with other fixing posts to continue cutting in the second direction without disassembling the lens. The cross-shaped groove 2 guides the debris to flow out from both ends during the cutting process, keeping the working area clean. Through the above design, this invention achieves efficient multi-angle cutting of lenses, reduces operation steps and sources of error, and improves processing accuracy and yield.
