Description

Technical Field

[0001] This utility model relates to the field of lens assembly device technology, specifically a high-precision optical lens assembly device. Background Technology

[0002] High-precision optical lenses are core components of modern optical technology and are widely used in scientific research, medical treatment, industrial inspection, aerospace, consumer electronics and other fields.

[0003] High-precision optical lenses require assembly and fixation with the lens holder during processing, and the lens holder needs to be clamped and fixed during assembly and fixation.

[0004] In the assembly of optical lenses and lens frames, there is often a lack of flexible and precise clamping and angle adjustment devices. During assembly, workers find it difficult to stably and easily fix the lens frame, leading to wobbling or shifting and affecting assembly accuracy. Furthermore, when different angles need to be adjusted on the outside of the lens frame, frequent manual adjustments are required, which is cumbersome, inefficient, and may even damage the lens or lens frame due to improper handling, making it difficult to meet the demands for efficient and precise assembly.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a technical solution, please refer to Figure 1 and Figure 2 A high-precision optical lens assembly device includes: a worktable 1 and a clamping mechanism 2. The clamping mechanism 2 is assembled in the inner cavity of the worktable 1. The clamping mechanism 2 includes a bidirectional lead screw 21. A first motor 22 is assembled on the right side of the bidirectional lead screw 21. Nuts 23 are threadedly connected to both sides of the outer side of the bidirectional lead screw 21. A limit mechanism 3 is assembled on the top of the nut 23.

[0025] The limiting mechanism 3 includes a T-shaped slide plate 31, which is connected to a nut 23. A vertical plate 32 is mounted on the upper end of the T-shaped slide plate 31, and a C-shaped clamping plate 33 is mounted on the outside of the vertical plate 32. A second motor 36 is mounted on the top of the T-shaped slide plate 31 on the top left side of the worktable 1. A worm gear 35 is connected to the output end of the second motor 36, and a worm wheel 34 is meshed with the outside of the worm gear 35. The worm wheel 34 is connected to the side of the C-shaped clamping plate 33 near the second motor 36.

[0026] Please see Figure 3 and Figure 4The worktable 1 can support the first motor 22, which is connected to the worktable 1 via a bracket. The two-way lead screw 21 has threads on both sides, and the threads on both sides are in opposite directions. The two-way lead screw 21 can drive the two nuts 23 to move relative to each other or away from each other by rotating. The T-shaped slide plate 31 can slide on the top of the worktable 1 and guide the nuts 23 to make them move in a straight line, preventing them from rotating. The C-shaped clamp 33 can support the lens frame and can drive the lens frame to rotate. The worm gear 34 can be driven by the worm 35, which can be driven by the second motor 36.

[0027] A rotating arm 37 is connected to the end of the C-shaped clamp 33 away from the second motor 36. A torsion spring 38 is connected between the rotating arm 37 and the vertical plate 32. The rotating arm 37, in conjunction with the torsion spring 38, can drive the C-shaped clamp 33 to rotate after being driven by the C-shaped clamp 33 on the other side, and then automatically return to its original position.

[0028] The inner side of the C-shaped clamp 33 is fitted with a rubber pad, and the outer side of the C-shaped clamp 33 is fitted with reinforcing ribs. A bearing is fitted at the junction of the C-shaped clamp 33 and the vertical plate 32. The rubber pad can improve the clamping effect of the C-shaped clamp 33 on the lens frame. At the same time, the deformation characteristics of the rubber can prevent damage to the lens frame. The reinforcing ribs improve the strength of the C-shaped clamp 33, and the bearing improves the stability of the C-shaped clamp 33 when rotating. The C-shaped clamp 33 is composed of a rotating shaft and a C-shaped plate.

[0029] The bottom of the second motor 36 is equipped with a base, which is connected to the T-shaped slide plate 31. The worm gear 35 is connected to the vertical plate 32 through a bearing with a seat. The base improves the stability of the second motor 36 during transmission. Both the second motor 36 and the first motor 22 are equipped with controllers. The second motor 36 and the first motor 22 are stepper motors commonly used in the prior art, and have a self-locking function.

[0030] The inner cavity of the workbench 1 is provided with a slot, and the top of the slot is provided with a guide groove 11. A bearing is connected between the slot and the double-acting lead screw 21. An assembly plate 12 is installed on the top of the inner cavity of the slot. The assembly plate 12 is connected to the double-acting lead screw 21 through the bearing. The slot facilitates the assembly of the clamping mechanism 2, and the assembly plate 12 can support the double-acting lead screw 21.

[0031] A T-shaped support plate 4 is inserted into the top of the workbench 1, and a spring connects the T-shaped support plate 4 to the workbench 1. The T-shaped support plate 4 can move up and down on the top of the workbench 1 to support the lens frame. The top length of the T-shaped support plate 4 is greater than the length of the lens frame, so that the lens frame can resist the T-shaped support plate 4 and descend when rotating.

[0032] In this design, the lens holder of the optical lens is placed on top of the T-shaped load-bearing plate 4. The first motor 22 is started to drive the bidirectional lead screw 21 to rotate, which in turn drives the two nuts 23 to move relative to each other, thereby driving the two limiting mechanisms 3 to move relative to each other. The lens holder is clamped by two sets of C-shaped clamps 33. The operator assembles the lens holder with the lens. At the same time as the assembly, the second motor 36 is driven to drive the worm gear 35 to rotate, which in turn drives the worm wheel 34 to drive the C-shaped clamps 33 to rotate, thereby driving the lens holder to rotate, thus assembling the lens holder at different angles.

[0033] The addition of a first motor 22, a bidirectional lead screw 21, and a nut 23 drives two sets of limiting mechanisms 3 to move relative to each other, thereby quickly fixing the lens frame and facilitating its installation. At the same time, the addition of a worm gear 34, a worm 35, and a second motor 36 allows the lens frame to rotate when it is fixed, thus fixing it at different angles. Furthermore, the characteristics of the worm gear 35 and the worm wheel 34 are used to self-lock the position of the C-shaped clamp 33, thereby improving the stability of the lens frame during assembly.
