Image acquisition module and lens mount thereof

Abstract

The invention provides an image pickup module and a lens mount thereof, wherein the lens mount comprises a body and an adjusting part, the body comprises an inner hole whose bottom and side surfaces are respectively attached with the top and side surfaces of an image sensing component, the adjusting part connected with the body can slide relatively to the body. The adjusting part of the lens mount can move relatively to the body, the top and bottom surfaces of the body and the bottom of the adjusting part have high accuracy, to avoid the error of the lens mount of the prior image pickup module corresponding to the image pickup module, to improve the imaging accuracy of the image pickup module.

Description

technical field [0001] The invention relates to an image capture module and its lens holder, in particular to an image capture module with lens adjustment function and its lens holder. Background technique [0002] CCD or CMOS image capture modules are widely used in industrial and medical fields, such as digital cameras. Such as figure 1 Shown, be a kind of existing CCD image capturing module 1, this CCD image capturing module 1 comprises a lens seat, a PCB board 12, and an image sensing assembly 13 and a lens 14, this image sensing assembly 13 is placed on the PCB board 12 and electrically connected to the PCB board 12, the lens 14 is screwed to the lens mount 11, and the lens mount 11 is fixed on the PCB board 12 by screws. Electronic circuit is arranged on the PCB board 12, and it has certain thickness, because the electronic circuit near two threaded holes 121 on the PCB board 12 has different thicknesses, after lens mount 11 is fixed on PCB board 12 by screw, the axi...

Problems solved by technology

Electronic circuit is arranged on the PCB board 12, and it has certain thickness, because the electronic circuit near two threaded holes 121 on the PCB board 12 has different thicknesses, after lens mount 11 is fixed on PCB board 12 by screw, the axis of lens 14 141 is easy to occur with the sensing center 131 of the image sensing component 13 as figure 2 Angle deviation shown, so that the image sensed by the image sensing component 13 is blurred and distorted

[0003] In addition, the lens mount 11 and the lens 14 will produce dimensional errors during the manufacturing process, and the image sensing component 13 will also produce dimensional errors during the packaging process. Therefore, the above errors will accumulate after being assembled together to form the image capture module 1, which is easy to cause like image 3 The axis of the lens 14 shown deviates from the sensing center 131 of the image sensing component 13, making the image sensed by the image sensing component 13 unclear
