Problems solved by technology

[0003] Furthermore, the traditional lens barrel is integrally formed by plastic injection, and its internal dimensions are difficult to measure, so that it is impossible to confirm the positioning state of the lens when it is inserted, especially in the imaging lens composed of several lenses, it is difficult to detect the reasons for eccentricity, tilt, and poor positioning
Moreover, the processing lead angle of the injection mold parts may also cause the corresponding lead angle of the injection product, which will cause interference when the lens is assembled, and the components cannot reach the proper position

Embodiment Construction

[0011] Below, give some preferred embodiments of the present invention, and cooperate with accompanying drawing to be described in further detail as follows:

[0012] First, see figure 1 and figure 2 As shown, the integrated lens group 10 of a preferred embodiment of the present invention includes two boards 12, 14, and the two boards 12, 14 are respectively provided with several through-holes 22 that penetrate up and down. The boards 12 The bottom side and the top side of the plate body 14 are also provided with two connecting parts 24, 26 correspondingly connected. Relatively fitting, so that each through-hole 22 can be communicated correspondingly, and fix a lens 16, 18 (more than one lens is also possible) in each through-hole 22 and use positioning glue (or positioning ring) respectively, so that each of the The peripheral area of ​​the hollow 22 and the lenses 16 and 18 inside the hollow 22 can constitute the collective lens group 10 .

[0013] In view of this, since...

Abstract

The invention provides an integrated lens group and a manufacturing method thereof. The integrated lens group is composed of a plurality of board bodies which are oppositely adhered; a plurality of hollows are respectively formed on each of the board bodies correspondingly; and one or more lenses are respectively arranged in each hollow. The manufacturing method of the integrated lens group adopts the following steps: a plurality of board bodies with a plurality of hollows are firstly provided, then the lenses are respectively arranged in the hollows of each board body, finally the board bodies are oppositely adhered, so that the peripheral areas of the hollows and the lenses in the hollows can correspondingly form a plurality of lens groups which can be cut and separated.

Description

technical field [0001] The present invention relates to the technical field of optical lens, and more specifically relates to an integrated lens group and a manufacturing method thereof. Background technique [0002] The known optical lens is composed of components such as a lens holder, a lens barrel, and a lens. The mechanism positioning components such as the lens barrel and the lens holder are mostly made of plastic injection, which is conducive to mass production. However, with the application trend of shrinking image sensors, the size of the optical lens must also be reduced accordingly. In this way, the use of plastic injection to make the positioning components such as the lens barrel and the lens mount will not meet the dimensional accuracy. Requirements, and the heat-resistant temperature of plastic products in the packaging and manufacturing process of optical lenses is also limited. Therefore, it is very necessary to develop mechanism positioning components with...
