Problems solved by technology

However, for a lens with a large air gap between the two lenses, if a metal gasket is used to control the air gap, the weight of the lens will increase, and the processing accuracy of the metal mirror gasket is also unstable, and the tolerance distribution is wide; the plastic gasket is too thick, and the product fall

Example Embodiment

[0009] Such as figure 1 Shown is a schematic diagram of the lens air interval control of the conventional lens barrel 34. Conventional lens air separation control with a small air separation between the two lenses is controlled by adding a gasket 33 between the front lens 31 and the rear lens 32, that is, the gasket 33 presses the front lens 31 and then the latter lens 32 is assembled. However, for a lens with a large air gap between the two lenses, if a metal gasket is used to control the air gap, it will increase the weight of the lens, and the processing accuracy of the metal lens gasket is also unstable and the tolerance distribution is wide; Difficult to mold, easy to deform and unstable quality; too thick washer, assembly will be more difficult.

[0010] The invention provides a mobile phone lens barrel with a large air gap, such as figure 2 Shown is a schematic diagram of a mobile phone lens barrel with a large air gap according to the present invention. In the present ...

Abstract

The invention relates to mobile phone lens barrel with a large air space. At least two lens abutting surfaces are machined on the inner wall of the lens barrel in an integrated molding manner. According to the mobile phone lens barrel, the air space between two mounted lenses is directly controlled by the lens barrel; after the lenses are mounted into the lens barrel, spot gluing is performed forrealizing fixation. One assembling fitting can be reduced, thereby reducing lens weight and saving cost. An accumulated error caused by the fittings is reduced, and product yield rate is improved. Furthermore an assembling process is simplified and efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mobile phone lens barrels, in particular to a mobile phone lens barrel with a large air gap. Background technique [0002] At present, various types of lenses rely on shading sheets, plastic gaskets or copper gaskets to control the air gap between the two lenses. However, for a lens with a large air gap between the two lenses, if a metal gasket is used to control the air gap, the weight of the lens will increase, and the processing accuracy of the metal mirror gasket is also unstable, and the tolerance distribution is wide; the plastic gasket is too thick, and the product falls off. Molding is difficult, easy to deform and unstable in quality; gaskets are too thick, and assembly will be difficult. The current method of adding gaskets between the lenses is not suitable for the lens structure with a large air gap between the two lenses, so a new structure needs to be developed to improve these problems. ...
