Description

Lens carrier

The invention relates to a lens manufacturing process, in particular to a lens carrier used in lens dispensing.

In recent years, with the development of optical products, the range of applications of lenses has continued to expand, such as digital cameras, mobile phones with camera functions and other electronic products. For electronic products, especially consumer electronic products, the trend is to be lighter and thinner, and the corresponding lenses are becoming smaller and smaller, and the precision requirements are getting higher and higher. Therefore, the lens assembly process also requires higher precision and stability to ensure assembly efficiency and assembly yield.

The lens usually includes a lens barrel, a lens group, a spacer ring, and a filter. The lens group, the spacer ring and the filter are sequentially fixed in the lens barrel along the optical axis direction, and the spacer ring is closely fixed with the filter. In the assembly process of the lens, the filter and the spacer ring are generally fixed by a dispensing process. In the dispensing process, an ultraviolet curing gel (Ultraviolet Glue, UV glue) is uniformly coated on the spacer ring, and then the filter is attached to the spacer ring, and the UV adhesive is cured by ultraviolet light to fix the filter.

When dispensing a plurality of lenses, the plurality of lenses are usually placed on a carrier, and then the carriers are placed on the dispenser to sequentially dispense the lenses. During the dispensing process, after the dispensing needles are dispensed for each lens, some of the glue remains on the dispensing needles. These residual glues are easy to absorb dust and the like, which causes the dispensing needles to be contaminated. In addition, after the glue remaining on the dispensing needle solidifies, it will affect the flow direction of the glue of the dispensing needle, thereby affecting the dispensing precision of the dispensing needle, thereby affecting the assembly yield of the lens.

In view of this, it is necessary to provide a lens carrier that can clean the dispensing needle in time and improve the lens assembly yield.

A lens carrier for use in lens dispensing, the lens carrier having a bearing surface for carrying a plurality of lenses, the carrier surface being provided with a cleaning member for wiping the dispensing needle.

In the process of lens dispensing, when the above lens carrier is used, the dispensing needle can be wiped and cleaned at the cleaning part in time, thereby improving the dispensing precision of the dispensing needle, thereby improving the assembly yield of the lens.

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

Referring to FIG. 1 , a lens carrier 100 used for dispensing a lens provided by an embodiment of the present invention has a bearing surface 10 for carrying a plurality of lenses 200 , and the bearing surface 10 is provided with a cleaning component 20 for cleaning the component 20 . The dispensing needle 300 is wiped to clean the dispensing tip 300.

In this embodiment, the lens carrier 100 has a square shape, and the bearing surface 10 is a rectangular surface. It can be understood that the shape of the lens carrier 100 and the bearing surface 10 is not limited to the embodiment. The shape of the lens carrier 100 may be a disk shape or the like. The shape of the bearing surface 10 may also be a circular shape or the like. In order to facilitate positioning of the lens 200 thereon, the receiving surface 10 is preferably formed with a plurality of receiving holes 30 for receiving the lens 200. The plurality of receiving holes 30 are arranged in a matrix on the bearing surface 10, and the distance between each two adjacent receiving holes 30 is equal. It can be understood that the plurality of receiving holes 30 are arranged on the bearing surface 10 and The spacing between the two can be determined according to actual needs, and is not limited to the embodiment. Preferably, the inner diameter of the receiving hole 30 is substantially the same as the outer diameter of the lens 200, so that the position of each lens 200 on the bearing surface 10 can be further accurately positioned.

The cleaning member 20 can be annular, so that the cleaning of the dispensing needle 300 can be facilitated. Specifically, the cleaning member 20 can be annular, elliptical or square. In the embodiment, the cleaning member 20 is disposed at a corner of the bearing surface 10, which is an annular sponge that adsorbs alcohol. It can be understood that the position of the cleaning member 20 on the bearing surface 10 is not limited to the embodiment, and may be disposed at other positions such as the center of the bearing surface 10, and the material thereof is not limited to the embodiment, for example, It may be cotton adsorbed with alcohol or only one piece of dry cotton. If the material of the cleaning member 20 is soft, a fixing cylinder may be sleeved around the cleaning member 20 to position the cleaning member 20.

Preferably, the bearing surface 10 is further formed with a pair of bit grooves 40 for correcting the dispensing needle 300. Preferably, the annular cleaning member 20 is wrapped such that the dispensing needle 300 can be directly corrected by the alignment groove 40 after the cleaning member 20 completes cleaning of the dispensing needle 300.

In the lens dispensing process, when the lens carrier 100 is used, the dispensing needle 300 can be moved back to the cleaning member 20 in time to improve the dispensing accuracy. In a specific use, the dispensing needle 300 can be controlled to be moved by a program setting, and the dispensing needle 300 can be glued to a certain amount, such as one, two or three, that is, moved back to the cleaning member 20 to wipe. . By means of the alignment groove 40 provided on the bearing surface 10 surrounded by the cleaning member 20, the dispensing needle 300 can be positionally corrected after each movement back to the cleaning, so that the dispensing needle 300 can be prevented from continuing. A large cumulative error occurs after the multi-lens lens 200, so that the dispensing accuracy can be further improved, thereby improving the assembly yield of the lens 200.

In addition, those skilled in the art can make other changes in the spirit of the present invention. Of course, these changes in accordance with the spirit of the present invention should be included in the scope of the present invention.
