Array type barrel group

Array tube group

This creation is related to the field of optical lens technology, and more specifically refers to an array of lens barrels.

The conventional optical lens is composed of a combination of a lens holder, a lens barrel and a lens. The positioning elements of the lens barrel and the lens holder are mostly made of plastic injection, which is beneficial to mass production. However, with the trend of application of image sensor shrinking, the size of the optical lens must also be reduced. As a result, the positioning of components such as the lens barrel and the lens holder by plastic injection method cannot meet the dimensional accuracy. Requirements, and the heat resistance temperature of plastic products in the packaging process of the optical lens is also limited. Therefore, it is necessary to develop a mechanism positioning component with higher precision and high thermal stability, and it is also advantageous for the use of optical lenses with higher precision requirements (such as a focus-free lens), or for automated assembly.

The main purpose of this creation is to provide an array of lens barrels that can solve the defects of the previous ones, which have high precision and thermal stability, and can effectively improve the assembly efficiency of optical lenses and the use of optical lenses for higher precision requirements. .

The reason is that, in order to achieve the above objectives, the present invention provides an array of lens barrels, which are formed by juxtaposing a plurality of barrels.

In the following, a number of preferred embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1 and FIG. 2, the array of lens barrels 10 of the preferred embodiment is constructed by Most of the lens barrels 12 are connected in parallel, and are formed in the following manner: a plurality of transparent spaces 24 are formed on the plurality of plate bodies 22 made of a silicon wafer by dry etching or wet etching, and then each of the plates is formed. 22, when they are attached together, each of the permeable spaces 24 can correspond to the internal space of the lens barrel 12, thereby forming an array lens barrel 10 having a plurality of lens barrels 12.

In addition, a multi-stage lens barrel 12 can be formed on the side of a glass or metal substrate 30 by means of micro-electroforming (LIGA), as shown in FIG. 3, and becomes the array type lens barrel 10.

Furthermore, the number of transparent spaces 24 can be respectively cut on the glass or ceramic plate 22 by means of laser processing, and then the partial laser processed plates 22 can be bonded together to form a multi-mirror. The array lens barrel 10 of the tubular portion 12.

Therefore, the array lens barrel 10 of the present invention is applied to an assembly process of an optical lens for improving the assembly efficiency of the optical lens: it can be cut to produce a plurality of independent lens barrels 12 at a time, and then each of the lens barrels 12 An optical lens is formed separately from components such as a lens holder and a lens (not shown). The optical lens may be formed on each of the lens barrels 12 before the respective lens barrels 12 have been cut and separated, and then the optical lenses are separated and independent, thereby achieving an effect of improving the assembly efficiency of the optical lens.

As shown in FIG. 4, the array lens barrel 40 of the preferred embodiment of the present invention has substantially the same structure as the array lens barrel group 10, except that each of the lens barrels 42 is provided by one The plate-like connecting portions 44 are joined together.

As can be seen from the above, the array of lens barrels provided by the present invention can be made of silicon wafer, metal, glass or ceramic, and has high precision and thermal stability, and is designed by an array type. It can produce most optical lenses at one time, which can effectively improve the assembly efficiency of optical lenses and optical lens users for higher precision requirements. The reason is that this creation does comply with the requirements of new patents and is filed according to law.
