Apparatus for adjusting the degree of freedom using sensor in assembling optical device

Abstract

An apparatus for adjusting degrees-of-freedom during the assembly of an optical device using a sensor. The apparatus includes a degree-of-freedom adjustment unit having a holder and an error control portion linked with the holder; a plate-fixing unit having a fixed jig for firmly loading the fastening plate, an elevating means and a plunger for fixing the fastening plate; a laser generating unit for emitting a laser beam onto the image sensor on the PCB assembly which is loaded on the holder; a sensor unit for measuring a mounted status of the image sensor surface-mounted on the PCB plate; and a control unit displaying a current position and a quality decision factor of the image sensor on a monitor after comparing a measured value transmitted from the sensor unit with a previously established master reference value.

Description

technical field [0001] The present invention relates to an apparatus for adjusting the degree of freedom of an image sensor during assembly of an optical device of a digital camera, and more particularly, to an apparatus for adjusting a degree of freedom using a sensor during assembly of an optical device in which the position of the image sensor is detected by using a laser beam and By adjusting the current state, the mutual positions of the lens assembly and the surface-mounted image sensor on the PCB board can be accurately bonded, so that optical products with good quality can be mass-produced without distortion effects. Background technique [0002] During a typical manufacturing process of optical devices such as digital cameras and printed circuit boards (PCBs), image sensors and optical lens assemblies are connected and assembled together. [0003] Specifically, a PCB assembly is formed by surface-mounting an image sensor as an imaging element on a PCB printed with l...

AI Technical Summary

Problems solved by technology

The problem comes from the fact that the image sensor is being assembled on the PCB, but it is not properly bonded to the PCB in three or six axis degrees of freedom, such as slope angle, height, width, depth, rotation, etc. etc., and the adjustment of this degree of freedom is also a very difficult task

[0006] Therefore, since the position of the degree of freedom in three or six axes changes along with the focal length of the lens when assembling the PCB assembly on which the image sensor is mounted and the lens assembly, image distortion occurs, thereby deteriorating the image quality
