Abstract

The invention discloses a locating device used for a camera lens assembly and a debugging structure of a fine-tuning visual angle. The locating device comprises a mounting frame, a lens assembly and a clamping and positioning assembly, wherein the lens assembly is installed on the clamping and positioning assembly; the clamping and positioning assembly is installed on the mounting frame; the debugging structure is characterized in that an infrared source is added on the mounting frame; and the clamping and positioning assembly and the infrared source are respectively connected with a computerprovided with debugging software. The locating device has a simple structure, is used for installing the lens assembly and performs the action on stabilizing and locating the lens assembly. In addition, the structure of the locating device is optimized on multiple aspects, on one hand, the lens assembly is further stabilized and positioned, and on the other hand, a lens visual angle of the lens assembly is convenient to regulate. In the using process, the locating device can be stably and reliably operated and can be suitable for various working places. The debugging structure is simple and convenient to operate, has high detection efficiency and can be widely suitable for detection occasions with the high requirement on the symmetry of the lens assembly visual angle.

Description

technical field [0001] The invention relates to the technical field of camera lens assembly installation, in particular to a positioning device for a camera lens assembly and a debugging structure for fine-tuning an angle of view. Background technique [0002] The application of optical sensing and positioning technology in the field of large-area touch products has become more and more extensive and mature; and the application of lenses as standard basic devices for optical sensing and positioning technology solutions is becoming more and more common. Arrange several groups of lenses at specific positions on the screen, and the lenses capture light changes. Through the feedback and calculation of the changes in the light of each lens, the specific touch position is known and an appropriate response is made. This constitutes the current mainstream solution for optical sensing positioning technology. . The positioning accuracy of the lens used for touch products is very high...

AI Technical Summary

Problems solved by technology

The assembly process of the lens, lens fixing bracket and CMOS / CCD board may cause the left and right angles of the lens to be asymmetrical, that is, the angle of view of one side exceeds the design requirements, and the angle of view of the other side does not meet the design requirements

This often leads to blind spots when using touch products

[0004] To sum up, the current deficiencies in the field of view angle of camera lens components are as follows: there is a left-right asymmetry in the view angle of the lens assembly during the assembly process, and there is a lack of positioning, detection and fine-tuning of this left-right asymmetry phenomenon in practice.
