[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] Example:

[0027] like Figure 1-Figure 6 As shown, the utility model provides a device for gluing and centering an optical lens, comprising a base 1 and a plurality of enclosures 2 arranged on the base 1. The enclosure 2 is in the shape of an arc plate. The plurality of enclosures 2 are distributed around the base 1 so that the plurality of enclosures 2 are enclosed in a cylindrical shape. In practice, the enclosure 2 and the base 1 are a whole, which can be made of a metal pipe. The enclosure 2 can also be welded to the base 1. An operating gap 3 is provided between two adjacent enclosures 2, so that when the lens 9 is placed between the plurality of enclosures 2, the edge of the lens 9 protrudes between the operating gaps 3. There are at least two enclosures 2, as long as at least two operating gaps 3 can be formed.

[0028] When the optical lens gluing and centering device of the utility model is used, the lens 9 coated with glue is placed between the two enclosures 2. Under the action of gravity, the lens 9 falls to the bottom and is supported by the base 1. The two or more lenses 9 to be bonded are aligned and bonded together through the limiting effect of the two enclosures 2. Since the lens 9 needs to be taken and placed between the two enclosures 2, the spacing between the enclosures 2 needs to be greater than the diameter of the lens 9. This may result in poor alignment of the lens 9. In addition, after the lens 9 is placed, it may tilt against the enclosure 2 and not completely fall to the bottom and fit the base 1.

[0029] The finger can touch the edge of the lens 9 at the operating gap 3, and then the lens 9 can be rotated by moving the lens 9. Then all the lenses 9 in the tilted state rotate and fall as a whole under the action of gravity or pressure and fit on the base 1. At the same time, if the lens 9 is not aligned, the lens 9 will also contact the enclosure 2 during the rotation process. If a certain position of the lens 9 is not aligned and bulges, the lens 9 rotates and contacts the enclosure 2 multiple times, so that the bulging part will be pushed to be flush, thereby achieving the effect of the two lenses 9 being aligned. Better guarantee the quality of bonding.

[0030] In this embodiment, two enclosures 2 are provided. The two enclosures 2 are arranged opposite to each other. The two ends of the enclosure 2 are provided with a knife-edge shape, and we call the knife-edge-shaped part a knife-edge portion 7. When the lens 9 is placed between the two enclosures 2, the portion of the lens 9 extending into the operating gap 3 contacts the knife-edge portion 7 of the enclosure 2. During the rotation of the lens 9, its edge rolls along the knife-edge. If there is a lot of glue between the lenses 9, the excess glue will be squeezed out along the edge of the lens 9. At the same time, the squeezed glue contacts the knife-edge portion 7 of the enclosure 2 and is then scraped off by the knife-edge portion 7 of the enclosure 2, thereby cleaning up the excess glue.

[0031] In this embodiment, the upper surface of the base 1 is arranged in a slope shape at the operating gap 3, thereby forming a liquid guiding slope 8. When a large amount of glue is scraped off by the blade 7, the glue flows down to the liquid guiding slope 8 and then flows away along the liquid guiding slope 8, thereby preventing the glue from flowing back to the lens 9.

[0032] In this embodiment, the inner side of the top of the enclosure 2 is provided with a chamfer so that the opening of the centering device is in a trumpet shape, which makes it convenient for the lens 9 to be placed between the two enclosures 2 through the opening.

[0033] In this embodiment, a circular hole is provided at the center of the base 1 so that the base 1 is in a circular ring shape. The base 1 is arranged in a stepped shape. If the lens 9 is a convex lens, the protruding part of the lens 9 can extend into the circular hole, thereby better placing the lens 9.

[0034] In this embodiment, an adjustment belt 4 is also included. The adjustment belt 4 is sleeved on the outside of the enclosure 2 and is located at the bottom of the enclosure 2. Specifically, the adjustment belt 4 is made of rubber band, which can be deformed and then stretched to generate elastic force. The adjustment belt 4 is in the shape of a belt, and the area it covers is the area where the edge of the lens 9 is located after the lens 9 is placed in. When the lens 9 is placed in, the adjustment belt 4 located at the operating gap 3 on both sides is first opened, and then the lens 9 can be placed in. After loosening the adjustment belt 4, the adjustment belt 4 shrinks and then contacts the edge of the lens 9 inside the operating gap 3. Figure 6 As shown, the adjusting belts 4 on both sides clamp the lens 9. If the adjusting belts 4 are rotated, the lens 9 can be driven to rotate.

[0035] In practice, if the lens 9 is moved by fingers, it is difficult to ensure that the force applied by the fingers is stable, which may cause the lens 9 to deflect and shake between the enclosure 2, and it is difficult to ensure that the lens 9 is always concentric with the circular hole of the base 1, which may cause the two bonded lenses 9 to be misaligned, making it difficult to ensure quality. However, the adjustment belt 4 can ensure that the forces applied to the lens 9 by the two operating gaps 3 are equal, so that the lens 9 is centered and the alignment effect is good. In actual operation, the adjustment belt 4 can be moved by fingers without directly touching the lens 9.

[0036] In this embodiment, the outer wall of the enclosure 2 is also protruded with a plurality of rollers 5. The adjustment belt 4 is sleeved outside the plurality of rollers 5. The rollers 5 are provided to make the rotation of the adjustment belt 4 smoother. At the same time, if the adjustment belt 4 is subjected to uneven force at various locations, it can be easily rotated under the action of elastic force, thereby ensuring that the tension of the adjustment belt 4 is the same at various locations. This ensures that the forces on both sides of the lens 9 are the same, and better ensures that the lens 9 is centered.

[0037] In this embodiment, the thickness of the adjustment belt 4 decreases gradually from top to bottom along the height direction of the enclosure 2. This requires a greater force to stretch the upper part of the adjustment belt 4. After the lens 9 is inserted, the adjustment belt 4 is stretched. At this time, since the upper and lower forces of the adjustment belt 4 are the same, the degree of stretching of the upper part of the adjustment belt 4 is less than that of the lower part. Figure 5 As shown, as for the whole adjusting belt 4, its upper part is inward and its lower part is slightly outward. This makes the force applied by the adjusting belt 4 to the lens 9 have a component force to press the lens 9 downward. This better presses the lens 9 between the two enclosures 2, and then makes the two bonded lenses 9 close to each other, and better ensures the bonding effect.

[0038] In this embodiment, a plurality of balls 6 are disposed on the surface of the base 1. The plurality of balls 6 are distributed around the circular hole and protrude from the upper surface of the base 1. After the lens 9 is placed, it directly contacts the balls 6. This makes the rotation of the lens 9 smoother and also prevents the lens 9 from being worn due to rotation.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
