Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a flowchart of an assembly process method of a camera according to an embodiment of the present invention.

In a specific embodiment, a method for assembling a camera is provided, which includes:

step S1: the base 2, to which the image chip 4 and the flexible circuit board 3 are connected in this order from the bottom, is inverted so that the top faces downward.

Firstly, the image chip 4 is carried on the flexible circuit board 3, the optical filter 5 is fixedly connected with the bottom of the base 2 through glue, then the flexible circuit board 3 fixed with the image chip 4 is fixedly connected on the base 2, and the image chip 4 and the optical filter 5 are aligned with the bottom inlet of the base 2. The base 2 is inverted with the top facing downward, in preparation for screwing the lens 1 into the base 2 from the bottom to the top.

Step S2: the lens 1 is rotated into the base 2 from bottom to top, and the distance between the lens 1 and the image chip 4 is adjusted, so that the focus of the lens 1 falls on the image chip 4.

Wherein, in the assembling process, camera lens 1 is from upwards screw in base 2 down, and gravity can make the dust that camera lens 1 and base 2 friction produced down, also be exactly the outside of the module of making a video recording, and the later stage can be cleared up to reduce the stain on optical filter 5, improve the yields. Or, because the inside screw thread of the cavity of base 2 is the internal thread, and the internal thread is down circling, and the outer screw thread of the cylinder of camera lens 1 is the external screw thread, and the external screw thread is up circling, consequently, the dust at groove can be driven into inside the screw thread by the internal thread of base 2, and can not fall in the cavity. The distance between the lens 1 and the image chip 4 is adjusted, and the judgment is carried out through the imaging of the image chip 4, and when the imaging is clearest, the focus just falls on the image chip 4.

Further, on the basis of the assembling process method of the camera, before rotating the lens 1 to adjust the distance between the lens 1 and the image chip 4, the method further includes:

and glue is arranged on a boss in the external thread of the lens 1.

Wherein, set up glue, camera lens 1 is from supreme rotatory back that gets into down, and camera lens 1 is fixed with base 2, has avoided the offset of camera lens 1 in base 2. Through 1 boss point round glue at the camera lens, glue can further restrict the dust because gravity flows down to glue can not pollute the cavity inside because the effect of gravity flows down.

As shown in fig. 2, 3 and 4, fig. 2 is a schematic structural diagram of a camera provided by an embodiment of the present invention, in which a lens 1 is not screwed into a base 2; fig. 3 is a schematic structural diagram of a camera provided in an embodiment of the present invention, in which a lens 1 is half-screwed into a base 2; fig. 4 is a schematic structural diagram of the camera provided by the embodiment of the invention after the lens 1 is completely screwed into the base 2.

In another specific embodiment, the invention further provides a camera prepared by the assembly process method.

The main structure of the camera is, from top to bottom, a lens 1, a base 2, an optical filter 5, an image chip 4, and a flexible circuit board. When the lens 1 is assembled, firstly, the image chip 4 is carried and fixed on the flexible circuit board, the optical filter 5 is attached to the bottom of the base 2, the base 2 containing the optical filter 5 is carried on the flexible circuit board, the optical filter 5 is aligned with the image chip 4, then the whole body is inverted, the lens 1 is rotated from bottom to top, the distance between the lens 1 and the image chip 4 is adjusted, so that the focus just falls on the image chip 4, and then the lens 1 and the base 2 are fixed by glue.

Further, on the basis of the camera, the inclination angle range of the cylindrical surface boss in the external thread of the lens 1 is 0-15 degrees inclusive.

Wherein, because glue is dotted on the boss of the cylindrical surface of the lens 1 before screwing in, in order to avoid the glue from flowing down too fast, the inclination angle of the boss of the lens 1 is reduced, the optimal inclination angle range is 0-15 degrees, and the glue is prevented from flowing down too fast.

Further, on the basis of the camera, the width range of the cylindrical surface boss in the external thread of the lens 1 is 0.05mm-0.5mm, including the end point value.

Wherein, in order to utilize the internal thread in the base 2 inner chamber to restrict the dust in a narrow and small space, can extend the boss in the external screw thread of camera lens 1, the width scope of best boss is 0.05mm-0.5mm, can restrict the dust in the boss.

It should be noted that the inclination angle and width of the convex platform, including but not limited to the above ranges, are within the protection range when designed according to the actual size of the whole lens.

The embodiments are described in a progressive manner in the specification, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other. The device disclosed by the embodiment corresponds to the method disclosed by the embodiment, so that the description is simple, and the relevant points can be referred to the method part for description.

The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
