Description

Technical Field

[0001] The present invention relates to the field of optical imaging technology, and in particular to an optical lens, a camera module and an assembling method of the optical lens. Background Art

[0002] With the popularization of mobile electronic devices, the relevant technologies of camera modules used in mobile electronic devices to help users obtain images (such as videos or images) have been rapidly developed and improved, and in recent years, camera modules have been widely used in many fields such as medical treatment, security, industrial production, etc.

[0003] In the process of improving the camera module's camera capabilities, there are three main factors that affect the image quality: First, the imaging quality of the lens. A high-quality lens can well correct the aberration of the optical system and achieve a higher image quality; second, the photosensitivity of the photosensitive chip. Generally speaking, the larger the single pixel area of ​​the photosensitive chip, the stronger its photosensitivity; third, ISP, that is, image processing algorithms. Different manufacturers have different algorithm capabilities and image optimization capabilities. Even if they have the same specifications of hardware, the images obtained after processing by different manufacturers will be quite different. Among the above factors, the quality of the lens determines the level of the imaging capability of the entire camera module. In order to obtain high-quality large-aperture lenses, wide-angle lenses, telephoto lenses, and higher-quality imaging, the number of lenses designed by manufacturers is increasing, reaching six, seven or even more. The increase in the number of lenses places very high demands on the accuracy of lens assembly. However, due to the existence of assembly tolerances and component tolerances, the more lenses there are, the greater the tolerance of the final lens molding, which affects its imaging quality. At the same time, large aperture and wide-angle lenses are also more sensitive, requiring higher lens assembly accuracy. In short, the existence of component tolerances and assembly tolerances greatly affects the imaging quality and yield of the lens.

[0004] In order to overcome the above difficulties, the present invention provides a multi-group lens that can adjust the imaging quality of the lens through active correction. When the component tolerance and assembly tolerance are within a certain range, the imaging quality of the lens can be compensated through active calibration, and then multiple groups can be assembled and fixed by bonding with adhesive to form a lens with a complete optical system.

[0005] However, when assembling the above lens, it is necessary to use adhesive to bond and fix the upper and lower sub-lenses. However, the adhesive is in a liquid state when it is not solidified and has fluidity. There is a time interval between the two processes of setting the adhesive on the lens component and curing the adhesive. Therefore, the adhesive has a tendency to flow and diffuse to both sides in the adhesive drawing area. At the same time, when setting the adhesive in the adhesive drawing area, the adhesive is generally a ring with an elliptical cross-section, and the upper and lower sub-lenses have a small gap after active calibration, which makes the adhesive squeezed and diffused to the inside and outside of the lens. The adhesive that diffuses to the outside affects the appearance and overflows, thereby affecting the motor or other components and thus the overall performance and reliability of the module; the adhesive that diffuses to the inside flows to the undesirable bonding position inside the lens, thereby affecting the performance and reliability of the lens; and it is easy to contact the adhesive bonding between the lens barrel and the lens of the sub-lens. The composition and performance of the two adhesives are different, which will affect the overall performance and reliability of the two adhesives. Summary of the invention

[0138] In one embodiment, in step S30, it includes:

[0139] S301: Arranging the first adhesive material 300 in the adhesive drawing area;

[0140] S302: Actively calibrate the optical system according to the measured imaging result to determine the relative position of the first lens component 100 and the second lens component 200.

[0141] In one embodiment, the glue drawing area is located on the first bottom surface 1021, and in step S301, the steps include:

[0142] The first adhesive material 300 is disposed on the adhesive drawing area on the first bottom surface 1021 .

[0143] In one embodiment, the glue drawing area is located on the second top surface 2021, and in step S301, the process includes:

[0144] The first adhesive material 300 is arranged on the adhesive drawing area on the second top surface 2021 .

[0145] In one embodiment, in step S30, it includes:

[0146] S301': Actively calibrate the optical system according to the measured imaging result to determine the relative position of the first lens component and the second lens component;

[0147] S302': moving the first lens component 100 or the second lens component 200 away;

[0154] Furthermore, the active calibration in the present application can adjust the relative positions of the first lens component 100 and the second lens component 200 in multiple degrees of freedom. Active calibration refers to controlling one lens component to adjust relative to another lens component to calibrate the entire optical system according to the measured resolution of the optical system, so that the axes of each lens component are adjusted consistently, thereby making the measured resolution of the optical system reach the standard. Figure 5A The relative position adjustment method in active calibration in one embodiment of the present invention is shown. In this adjustment method, the first lens component 100 can move along the x, y, and z directions relative to the second lens component 200 (i.e., the relative position adjustment in this embodiment has three degrees of freedom). The z direction is the direction along the optical axis, and the x and y directions are the directions perpendicular to the optical axis. Both the x and y directions are in an adjustment plane P, and the translation in the adjustment plane P can be decomposed into two components in the x and y directions.

[0155] Figure 5B FIG. 2 shows the rotation adjustment in active calibration of another embodiment of the present invention. In this embodiment, the relative position adjustment has Figure 5A In addition to the three degrees of freedom, a rotational degree of freedom is added, namely, adjustment in the r direction. In this embodiment, the adjustment in the r direction is a rotation within the adjustment plane P, namely, a rotation around an axis perpendicular to the adjustment plane P.

[0156] Further, Figure 5C The figure shows a relative position adjustment method with v and w direction adjustments added in the active calibration of another embodiment of the present invention. The v direction represents the rotation angle of the xoz plane, the w direction represents the rotation angle of the yoz plane, and the rotation angles of the v direction and the w direction can be synthesized into a vector angle, which represents the overall tilt state. In other words, by adjusting the v direction and the w direction, the tilt posture of the first lens component 100 relative to the second lens component 200 (that is, the tilt of the optical axis of the first lens component 100 relative to the optical axis of the second lens component 200) can be adjusted.

[0157] The adjustment of the six degrees of freedom of x, y, z, r, v, and w may affect the imaging quality of the optical system (for example, the resolution). In other embodiments of the present invention, the relative position adjustment method may be to adjust only any one of the six degrees of freedom, or a combination of any two or more thereof.

[0158] Further, in one embodiment, in the active calibration step, the movement also includes translation on the adjustment plane P, that is, movement in the x and y directions.

[0159] Further, in one embodiment, the active calibration further comprises: adjusting and determining the angle between the axis of the first lens component 100 and the axis of the second lens component 200 according to the measured resolution of the optical system, that is, the adjustment in the w and v directions. In the assembled optical lens or camera module, the axis of the first lens component 100 and the axis of the second lens component 200 may have a non-zero angle.

[0160] Furthermore, in one embodiment, active calibration also includes: moving the first lens component 100 in a direction perpendicular to the adjustment plane (i.e., adjustment in the z direction), and determining the relative position between the first lens component 100 and the second lens component 200 in a direction perpendicular to the adjustment plane P according to the measured resolution of the optical system.

[0161] Furthermore, in one embodiment, in the pre-positioning step, a gap is provided between the bottom surface of the first lens component 100 and the top surface of the second lens component 200 .

[0162] In one embodiment, in the active calibration step, the second lens component 200 may be fixed, the first lens component 100 may be clamped by a fixture, and the first lens component 100 may be moved under the drive of a six-axis motion mechanism connected to the fixture, thereby achieving the relative movement of the first lens component 100 and the second lens component 200 in the above six degrees of freedom. The fixture may be supported or partially supported on the side of the first lens component 100, thereby clamping the first lens component 100.

[0163] In one embodiment, in the active calibration step, the first lens component 100 may be fixed, the second lens component 200 may be clamped by a fixture, and the second lens component 200 may be moved under the drive of a six-axis motion mechanism connected to the fixture, thereby achieving the relative movement of the first lens component 100 and the second lens component 200 in the above six degrees of freedom. The fixture may be supported or partially supported on the side of the second lens component 200, thereby clamping the second lens component 200.

[0164] In the above embodiment, as an example, the optical lens is described as including a first lens component 100 and a second lens component 200. However, the number of lens components in the optical lens is not particularly limited, that is, the number of lens components is not limited to two, and the number of lens components may be three or four, etc., according to specific design requirements.

[0165] In the above embodiment, as an example, the number of lenses of the first lens component 100 is 1, and the number of lenses of the second lens component 200 is 5. However, the number of lenses in the first lens component 100 and the second lens component 200 is not subject to specific restrictions, that is, the number of lenses of the lens components is not limited to a specific number, and the number of lenses of the lens components can be 1 or more, etc., according to specific design requirements.

[0166] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
