Lens carrying fixture

Abstract

The invention relates to a lens bearing jig, which comprises a base and an upper cover. The base comprises a first surface and is provided with a plurality of accommodating holes for accommodating lenses. The upper cover and the base are overlapped, and the upper cover is positioned on the first surface and provided with a plurality of through holes which are communicated with the plurality of accommodating holes in a one-to-one correspondence way. Each accommodating hole comprises a bearing hole and a first conical hole which is communicated with the bearing hole, the first conical holes are formed on the first surface and extend to the inside of the base, and the pore size of each first conical hole is reduced along a direction away from the first surface. Each bearing hole is communicated with the each first conical hole at one end away from the first surface, and the pore sizes of connection parts between the first conical holes and the bearing holes are equal. The upper cover is further provided with a plurality of fixing rings which protrude towards the base direction and in one-to-one correspondence with the plurality of through holes, each fixing ring is arranged at one end of the corresponding through hole, which faces to the base, and each fixing ring is communicated with the corresponding through hole and accommodated in the corresponding accommodating hole.

Description

technical field [0001] The invention relates to a lens carrying jig, in particular to a lens carrying jig with an introduction channel and a fixing part. Background technique [0002] With the development of camera technology, lens modules are widely used in camera devices for various purposes. A lens module generally includes a lens barrel, a lens holder, a lens group accommodated in the lens barrel, a spacer ring, an optical filter, and the like. [0003] The processed finished lens is usually placed on a jig with a suction nozzle for subsequent processing, such as when assembling a lens module. Generally, the diameter of the receiving hole for carrying the lens in the jig is not much different from the outer diameter of the lens, thereby preventing the lens from shaking or falling in the jig. However, the aperture of the receiving hole for carrying the lens in the fixture is not much different from the outer diameter of the lens, which will bring certain difficulties to...

AI Technical Summary

Problems solved by technology

However, the aperture of the receiving hole for carrying the lens in the fixture is not much different from the outer diameter of the lens, which will bring certain difficulties to the placement of the lens. For example, it is difficult to align the lens picked up by the suction nozzle with the receiving hole for carrying the lens in the fixture , which makes it difficult for the lens to be placed in the receiving hole in the jig smoothly and in place, which requires additional manual placement, which greatly increases the corresponding operation time and corresponding cost

In addition, since the diameter of the receiving hole is not much different from the outer diameter of the lens, when the lens is placed in the receiving hole, it is easy to collide with the edge of the receiving hole. In severe cases, the lens may even be scratched and affect the quality of the lens. Generation of defective products
