Problems solved by technology

[0003] At present, the design of the focus ring needs to be designed according to the specifications of the lens. The module industry projects are updated rapidly, and a large number of lenses of different models and specifications are required. However, due to the differences in the performance parameters of each lens, the design habits of different lens manufacturers, Due to factors such as differences in lens manufacturing capabilities, different focus rings have poor versatility. Therefore, for production efficiency and cost considerations, basically one lens is matched with one focus ring, which costs a lot. At the same time, the maintenance of different focus rings, adjustment is also a problem

Embodiment 1

[0031] see Figure 1-7 , the present invention provides the following technical solutions: a universal focus ring suitable for different lenses, including a focus ring body 2, the bottom of the focus ring body 2 is slidingly connected with a focus module, and the focus module includes several circles with diameters in order A focusing module is added, and the focusing module includes several movable rods 3 in a circular array.

[0032] Further, the bottom of the focus ring body 2 is provided with several circles of through holes 5 corresponding to the focus modules, and the diameter of the through holes 5 is 0.01 mm larger than that of the connecting rod 32 .

[0033] By adopting the above technical solution, the movable rod 3 is installed through the setting of the through hole 5 so that the movable rod 3 can slide in the through hole 5 .

[0034] Further, the movable rod 3 includes a focusing petal 31, a connecting rod 32 and a limiting block 33, wherein one end of the conn...

Embodiment 2

[0037] The difference between this embodiment and Embodiment 1 lies in: further, friction teeth 1 are provided on the circumference of the focus ring body 2 .

[0038] By adopting the above technical solution, it is convenient to rotate the focus ring body 2 .

[0039] Further, the implementation method of the universal focus ring applicable to different lenses according to the present invention includes the following steps:

[0040] (1) Friction teeth 1 are arranged on the circumference of the focus ring body 2 to facilitate the rotation of the focus ring body 2;

[0041] (2), the bottom of the focusing ring body 2 is provided with several circles of through holes 5, which is convenient for installing the movable rod 3;

[0042] (3) Put the lens 4 under the focus ring body 2, the focus ring body 2 presses the lens 4 downward, the edge of the lens 4 pushes the corresponding movable rod 3 upward, and the limit block 33 and the focus ring body 2 Contact for limit;

[0043] (4...

Abstract

The invention discloses a universal focusing ring suitable for different lenses. The universal focusing ring comprises a focusing ring body, wherein the bottom of the focusing ring body is slidably connected with a focusing module, the focusing module comprises a plurality of circles of focusing modules of which the diameters are sequentially increased, and each focusing module comprises a plurality of movable rods in an annular array. The invention further discloses an implementation method of the universal focusing ring suitable for different lenses. The universal focusing ring is advantagedin that a focusing structure is refined, a plurality of circles of annularly arrayed movable rods form an integral focusing petal, so the focusing structure can adapt to different shapes and quantities of lens petals, and universality of focusing of different lenses is realized, and the universal focusing ring can reduce jig cost, is universal for focusing of different lenses, is flexible and convenient to switch and use, has low error-tolerant rate, is convenient to maintain, reduces the use difficulty and improves the use efficiency.

Description

technical field [0001] The invention belongs to the technical field of focus rings, and in particular relates to a general focus ring applicable to different lenses and a realization method thereof. Background technique [0002] Camera modules are mainly used in mobile phones, tablet computers, drones, medical, security and other electronic products. In its manufacturing process, the focus ring needs to be used in the following processes: 1. Lens lock: lock the lens to the IR component or motor and fix it (thread combination); 2. Focusing process: adjust the lens to the module image The clearest position; 3. Torque test: Confirm the torque of the lens and IR components or motor in the early stage. [0003] At present, the design of the focus ring needs to be designed according to the specifications of the lens. The module industry projects are updated rapidly, and a large number of lenses of different models and specifications are required. However, due to the differences i...
