Problems solved by technology

Because the former lenses are independent of each other, it is difficult to meet the requirements for consistency, so it is impossible to focus multiple small lenses on the image plane at the same time, and manual focusing steps are required, so the process is cumbersome and the production cost is high.
Although the latter overcomes the shortcomings of the former, it also has many disadvantages. For example, the US patent No. US8023208, named "Miniature stacked glass lens module", has a low degree of freedom in design,

Example Embodiment

[0045] The method for assembling the array lens of the present invention will be further described in detail below in conjunction with the drawings and the embodiments of the present invention.

[0046] figure 1 It is a schematic diagram of the structure of an array lens according to an embodiment of the present invention. Such as figure 1 As shown, the array lens includes a lens barrel 70, an array lens group and a pressing ring 10. The lens barrel 70 has a light shielding layer 76, an array lens group, including a third lens group 60, a second spacer 50, a second lens group 40, a first spacer 30 and a first lens group 20.

[0047] The array lens, with the lens barrel 70 as the bottom layer, is mainly assembled by the third lens group 60, the second lens group 40, the first spacer 30, the first lens group 20 and the pressure ring 10 in sequence.

[0048] Preferably, a second spacer 50 is further provided between the third lens group 60 and the second lens group 40 to achieve a bett...

Abstract

The invention discloses an assembly method for an array-type lens. The assembly method includes the following steps: A, mounting a third lens set (60) in a lens barrel (70); B, assembling a second lens set (40); C, assembling a first spacer (30); D, assembling a first lens set (20); E, assembling a pressing ring (10). By the assembly method, a lens structure capable of correcting the problem of optical axis eccentricity can be utilized, and yield of the array-type lens is increased substantially by solving the problem of optical axis aligning.

Description

technical field [0001] The invention relates to the design and assembly technology of an array lens, in particular to an assembly method of an array lens. Background technique [0002] Existing array lenses include array lenses composed of several individual small lenses and wafer-level array lenses produced by WLO (Wafer Level Optics) technology. The former is difficult to meet the requirement of consistency because each lens is independent of each other, so multiple small lenses cannot be well focused and imaged at the image plane at the same time, and manual focusing steps are required, so the process is cumbersome and the production cost is high. Although the latter overcomes the shortcomings of the former, it also has many disadvantages. For example, the US patent No. US8023208, named "Miniature stacked glass lens module", has a low degree of freedom in design, and the lens is directly molded. Could not have been better refined in later stages. In addition, high-resol...
