Description

Adjustment mechanism and detection module

Technical Field

Background

In order to produce a precise Image on an Image sensor (such as a CMOS or CCD), it is necessary to ensure that the axis of the lens set of the camera is aligned perpendicularly to the center of an Image sensing Area (Image Detected Area) of the Image sensor.

However, in the manufacturing of the camera in the prior art, it is difficult to ensure that the axis of the lens group is precisely aligned vertically to the center of the image sensing area of the image sensor. The reason is that in the increasingly detailed manufacturing system, all components required by a product are not usually produced by a manufacturer, but are produced by parts manufacturers and then assembled by a system manufacturer, and even the components are more detailed, and image sensors such as CCDs, CMOSs and the like are produced by chip manufacturers and then delivered to other professional manufacturers for packaging and testing. The cost of the division system is reduced, but camera assembly manufacturers finally find that the axes of the optical components of the lens cannot be accurately and vertically aligned with the center of the image sensing area of the image sensor if the optical components are assembled according to a common process because the CMOS and the CCD are not accurately positioned during packaging.

Since the image sensor can not adjust the positioning error after the package is completed, at present, in order to eliminate the misalignment problem between the axis of the lens set and the center of the image sensing area of the image sensor, the purpose is usually achieved by adjusting the lens.

In this embodiment, the base 10 has a rectangular plate shape. In other embodiments, the base may be any shape that provides a deflecting platform, such as circular, diamond, etc.

It should be noted that the base 10 has a threaded hole therein for positioning the yaw.

In this embodiment, the pitch adjusting support 21 and the yaw adjusting support 11 are rotatably connected by a first positioning pin 13, and the first rotation axis is an axis of the first positioning pin 13.

Accordingly, the base 10 has a second positioning hole (not shown) for cooperating with the first positioning pin 13.

Specifically, the axis of the second positioning hole is perpendicular to the top surface of the base 10, and the axis of the corresponding first positioning pin 13 is perpendicular to the top surface of the base 10. When the adjusting mechanism works, when the deflection adjusting support 11 deflects in the plane parallel to the top surface of the base 10, the adjusting mechanism can stably drive the optical device to deflect in the plane parallel to the top surface of the base 10, so that the light propagation path passing through the optical device can be adjusted.

In this embodiment, the bottom of the yaw adjusting support 11 has a first positioning hole 110 engaged with the first positioning pin 13.

In addition, the center of the first through groove 16 is generally located at the center of gravity of the yaw adjustment support 11.

The center of the first through groove 16 is located on the center of gravity of the yaw adjusting support 11, that is, the center of gravity of the yaw adjusting support 11 is located at the first positioning pin 13, and in the process that the yaw self-locking driving structure 19 drives the yaw adjusting support 11 to deflect around the first positioning pin 13, the yaw adjusting support 11 can deflect stably and accurately, the yaw adjusting support 11 is not prone to tilting, so that the yaw adjusting support 11 has a good deflection effect, and the adjustment and fine adjustment of a transmission path of light entering a lens are facilitated.

The axial line of the deflection adjusting shaft 12 is parallel to the surface of the base 10, and the deflection amount of the deflection adjusting shaft 12 is not easy to generate in the longitudinal direction in the process of generating displacement, so that the displacement amount in the process of rotating and self-locking matching of the deflection adjusting shaft 12 and the deflection knob fixing piece 14 can be converted into the deflection amount of the deflection adjusting support 11 to the maximum extent.

In this embodiment, the fact that the swing knob fixing member 14 is disposed on the base 10 means that the swing knob fixing member 14 is fixedly connected to the base 10.

When the adjusting mechanism works, the two deflection self-locking driving structures 19 are matched with each other, so that the deflection adjusting support 11 realizes stable deflection. Specifically, when two deflection self-locking driving structures 19 are driven simultaneously, in the process that one deflection self-locking driving structure 19 drives the deflection adjusting support 11 to deflect, the deflection adjusting shaft 12 in the other deflection self-locking driving structure 19 moves in the direction away from the deflection adjusting support 11, and the two deflection self-locking driving structures 19 limit the degree of freedom of rotation of the deflection adjusting support 11 around the first positioning pin 13, so that the relative position of the deflection adjusting support 11 and the base 10 is stable, and preparation is made for positioning the deflection adjusting support 11 and the base 10.

In other embodiments, the number of the deflection self-locking driving structures is two, and the deflection self-locking driving structures can also be positioned on two sides of the deflection adjusting support.

It should be noted that the yaw self-locking driving structure 19 is close to the side of the yaw adjusting support 11.

Specifically, the first kidney-shaped hole 18 includes an arc kidney-shaped hole, and a radius of the arc kidney-shaped hole is equal to a distance from the arc kidney-shaped hole to the first positioning rotating structure.

In the process that the deflection self-locking driving structure 19 drives the deflection adjusting support 11 to deflect around the first positioning pin 13, the deflection adjusting support 11 is not easily interfered with the flange fixing block 17.

In the adjusting mechanism, the number of the yaw self-locking driving structures 19 is two, the number of the corresponding flange fixing blocks 17 is two, and the number of the corresponding first kidney-shaped holes 18 is two.
