Description

Technical Field

[0001] This utility model relates to the field of camera manufacturing equipment, specifically to a manual focus adjustment device. Background Technology

[0002] Camera modules are important electronic devices for image capture. Smart terminals such as smartphones, smart cars, and robots need to use camera modules to complete optical imaging and realize functions such as taking pictures, capturing and analyzing information, and visual interaction, which has led to a significant increase in the demand for cameras.

[0003] As the applications of cameras expand, the functional requirements for them also increase. In some areas, cameras are required to seamlessly switch between near and far objects without changing their position. This necessitates camera lenses capable of smooth zooming in and out during shooting, leading to the development of zoom lenses. Zoom lenses have wide-angle and telephoto ends, adjustable to different shooting distances, suitable for various shooting scenarios and subjects.

[0004] Performance evaluation of zoom lenses requires testing both the wide-angle and telephoto ends, thus necessitating the design of a manual focus testing device. Summary of the Invention

[0019] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0020] One such Figure 1-5The manual focusing device shown mainly includes a frame 1, an FFU (Fan Filter Unit) 2, a tabletop 3, a planar light source 4, and a teleconverter 5. The frame 1 is constructed entirely of profiles and consists of two layers. Two doors 101 are located at the back of the frame for easy installation and debugging. External black painted sheet metal 102 is provided for shielding. An FFU 2 is located at the top of the frame, and four feet 103 and four casters 104 are located at the bottom for stable installation and movement. The FFU 2 mainly consists of a fan 201, a high-efficiency filter 202, and a housing 203. When the device is running, the fan starts, drawing indoor air into the FFU. Driven by the fan, the air passes through the high-efficiency filter, which traps dust, bacteria, viruses, and other tiny particles. The filtered clean air is then evenly distributed vertically or horizontally, providing a clean air environment for the specific space. The platform 3 is equipped with a display screen 301, a slide rail 302, a slider 303, a material tray fixing block 304, a linear motion module 305, a planar light source 4, a teleconverter 5, a teleconverter bracket 501, and a test box 502. The display screen 301 is mounted on the display screen bracket and secured with screws. The display screen 301 is electrically connected to the main unit 306, which is located on the lower layer of the frame 1. The display screen 301 provides a more intuitive and clear display of the module images. The test box 502 is located in the center of the platform 3, fixed to a test box bracket, and secured with screws. The lens module is placed on the test box. The lens module is directly opposite the center of the teleconverter for easy adjustment of the lens focal length.

[0021] The material tray fixing blocks 304 are set on both sides of the table panel and fixed by screws, which makes it easy to place the material tray and convenient to pick up and put down the material.

[0022] A planar light source 4 is fixed on a planar light source placement platform 401 and connected to a light source controller 402, thus controlling the output of the light source. A transparent glass 403 is placed beneath the planar light source; the transparent glass has high transmittance of visible light, allowing the light emitted by the light source to pass through as much as possible. The light source placement platform 401 is positioned between linear motion modules 305 and is fixed in place with screws via two connecting blocks 404. The linear motion modules are screwed to both sides of the platform, enabling the planar light source to move linearly and adjusting the distance between the light source and the product.

[0023] The teleconverter 5 is mounted on the teleconverter bracket 501 and located at the center of the platform, and is fixed in place by screws. The teleconverter bracket is attached to the slider by screws, and the slider has a slide rail that allows the teleconverter to move left and right to adjust the focal length of the module lens on the test box.

[0024] The implementation steps and principles of this invention are as follows:

[0025] S1. By manually loading the module to be tested onto the test box, align the teleconverter with the module lens, start the light source controller, output the light source through the glass via a planar light source, use the teleconverter to adjust the lens focus and focus clarity, perform module testing, and display the module imaging results on the display screen after the test is completed.
