Description

Lens tray

technical field

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

Background technique

In recent years, with the development of optical products, the scope of application of lenses continues to expand, such as digital cameras, mobile phones with camera functions and other electronic products. For electronic products, especially consumer electronic products, the development trend is light weight and thinner, and the corresponding lenses arranged in them are also becoming smaller and smaller, and the requirements for precision are also getting higher and higher. Therefore, the lens assembly process also requires higher accuracy and stability to ensure assembly efficiency and assembly yield.

A lens usually includes a lens barrel, lens group, spacer ring and filter. The lens group, the spacer ring and the optical filter are sequentially fixed in the lens barrel along the direction of the optical axis, and the spacer ring and the optical filter are tightly fixed together. During the assembly process of the lens, the filter and the spacer ring are generally fixed by a dispensing process. In the glue dispensing process, first apply Ultraviolet Glue (UVglue) evenly on the spacer ring, then attach the filter to the spacer ring, and use UV light to cure the UV glue to fix the filter.

When performing glue dispensing operations on multiple lenses, usually the multiple lenses are placed on a tray, and then the tray is set on the dispensing machine to perform glue dispensing operations on these lenses in sequence. During the dispensing process, after the dispensing needle dispenses glue to each lens, there will be some glue remaining on the dispensing needle, and these residual glue is easy to absorb dust, etc., thus causing the dispensing needle to be polluted. In addition, after the glue remaining on the dispensing needle solidifies, it will affect the glue flow direction of the dispensing needle, thereby affecting the dispensing accuracy of the dispensing needle, and further affecting the assembly yield of the lens.

Contents of the invention

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

Disclosed is a lens carrier plate used for lens dispensing. The lens carrier plate has a carrying surface for carrying a plurality of lenses, and a cleaning component is arranged on the carrying surface, and the cleaning component is used for wiping dispensing needles.

In the lens dispensing process, when using the above-mentioned lens carrier plate, the dispensing needle can be wiped clean in time after dispensing, so as to improve the dispensing accuracy of the dispensing needle, thereby improving the assembly yield of the lens.

The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings.

detailed description

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

Referring to Fig. 1 , the lens carrying plate 100 used when the lens dispensing provided by the embodiment of the present invention has a carrying surface 10 for carrying a plurality of lenses 200, and a cleaning component 20 is arranged on the carrying surface 10, and the cleaning component 20 is used to wipe the dispensing needle 300 to clean the dispensing needle 300 .

In this embodiment, the lens carrier tray 100 is square, and the carrier surface 10 is a rectangular surface. It can be understood that the shapes of the lens tray 100 and the loading surface 10 are not limited to this embodiment, the shape of the lens tray 100 can also be a disk, and the shape of the loading surface 10 can also be a circle. To facilitate the positioning of the lens 200 thereon, preferably, a plurality of accommodating holes 30 for accommodating the lens 200 are formed on the carrying surface 10 . The plurality of receiving holes 30 can be arranged in a matrix on the bearing surface 10, and the distance between every two adjacent receiving holes 30 is equal. It can be understood that the arrangement of the plurality of receiving holes 30 on the bearing surface 10 The manner and the distance between them can be determined according to actual needs, and are not limited to this embodiment. Preferably, the inner diameter of the receiving hole 30 is approximately the same as the outer diameter of the lens 200 , so that the position of each lens 200 on the carrying surface 10 can be further accurately positioned.

The cleaning member 20 can be ring-shaped, so as to facilitate wiping the dispensing needle 300 , specifically, the cleaning member 20 can be in the shape of a ring, an ellipse, or a square ring. In this embodiment, the cleaning component 20 is arranged at a corner of the carrying surface 10 , which is a ring-shaped sponge adsorbed with alcohol. It can be understood that the position of the cleaning member 20 on the carrying surface 10 is not limited to this embodiment, it can also be arranged in other positions such as the center of the carrying surface 10, and its material is not limited to this embodiment, for example, it can also be It can be cotton adsorbed with alcohol or just a piece of dry cotton. If the material of the cleaning component 20 is soft, a fixing cylinder can be sleeved around the cleaning component 20 to position the cleaning component 20 .

Preferably, the bearing surface 10 is further formed with an alignment groove 40 , and the alignment groove 40 is used for correcting the dispensing needle 300 . Preferably, it is surrounded by an annular cleaning member 20 , so that the dispensing needle 300 can be calibrated directly by using the aligning groove 40 after the cleaning member 20 finishes cleaning the dispensing needle 300 .

During the lens dispensing process, when using the above-mentioned lens carrier plate 100, the dispensing needle 300 can be moved back to the cleaning part 20 for wiping in time, thereby improving the dispensing accuracy. In specific use, the movement of the dispensing needle 300 can be controlled by program setting, and the dispensing needle 300 can be used to dispens a certain amount of glue, such as one, two or three, and then move back to the cleaning part 20 for wiping. . And through the alignment groove 40 provided on the bearing surface 10 surrounded by the cleaning part 20, the dispensing needle head 300 can be moved back to clean each time to perform a position correction, thereby avoiding the continuous dispensing of the glue dispensing needle head 300. After a plurality of lenses 200 , a larger cumulative error is generated, so that the dispensing accuracy can be further improved, and thus the assembly yield of the lens 200 can be improved.

Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. In addition, those skilled in the art can also make other changes within the spirit of the present invention. Of course, these changes made according to the spirit of the present invention should all be included within the scope of protection claimed by the present invention.
