The first sub-lens 131 may further include at least one rounded edge 13132. The chord edge 13131 is not limited to a straight line segment, and may also be an arc-shaped line segment, or to fit any line segment of the central region 1311, or may be designed to fit an edge shape of the mobile electronic device. With respect to the original lens having a complete circle, the chord edge 13131 can also be understood as an edge of the lens with a part missing from the original. Then, for reducing the size of the first sub-lens 131 and the first bearing member 111, the existence of the chord edge 13131 is of great significance.

In some examples of the present invention, the side edge 1313 of the edge reduction lens may be formed by adjacently forming at least two line segments with different curvatures, so that the side edge 1313 of the edge reduction lens is not a complete circle. . In some examples of the present invention, the side edges 1313 of the shrink lens can be formed by line segments with the same curvature, such as a square lens.

In this example, the number of the chord edges 13131 and the round edges 13132 is one each. Each of the second sub-lens 132, the third sub-lens 133, the fourth sub-lens 134, and the fifth sub-lens 135 has a circular side. That is, the second sub-lens 132, the third sub-lens 133, the fourth sub-lens 134, and the fifth sub-lens 135 are each a circular lens.

It can be understood that, in other examples of the present invention, the number of the rounded edges 13132 may be 0, that is, the side edges 1313 of the shrink lens are all formed by the chord edges 13131. In other examples of the present invention, the number of the rounded sides 13132 may be one, and the number of the chorded sides 13131 may be two. In other examples of the present invention, the number of the rounded edges 13132 may be two, and the number of the chorded edges 13131 may be two. For example, two sides of the rounded edge 13132 are connected to the chorded edges 13131, respectively. Or, one side of one of the rounded edges 13132 is connected with the chord edge 13131 and the other rounded edge 13132. In other examples of the present invention, the number of the rounded sides 13132 may be one, and the number of the chorded sides 13131 may be three. The proportions and positions of the chord edges 13131 and the round edges 13132 can be set according to different requirements, such as symmetrical or asymmetrical settings, according to a predetermined size ratio, and the like.

FIG. 3B shows an embodiment of the hemming lens, and the hemming lens is the first sub-lens 131. Of course, it can be understood that the lens at other positions may be the hemming lens. In this example, the number of the rounded edge 13132 and the chorded edge 13131 of the shrink lens is two, and one of the rounded edge 13132 and the other of the rounded edge 13132 are oppositely disposed. The chord edge 13131 and the other chord edge 13131 are oppositely disposed. When the hemming lens is the first sub-lens 131, and the camera module 1 with the hemming lens is applied to the mobile electronic device 1000, the chord side 13131 is located in a length direction At this time, the proportion of the camera module 1 occupying the display screen of the mobile electronic device 1000 in the length direction decreases.

FIG. 3C shows an embodiment of the hemming lens. The hemming lens is the first sub-lens 131. Of course, it can be understood that the lens in other positions may be the hemming lens. The lens, in the present example, the side edges 1313 of the shrink lens include the chord edges 13131, and the number of the chord edges 13131 is four. When the hemming lens is the first sub-lens 131, and the camera module 1 with the hemming lens is applied to the mobile electronic device 1000, the camera module 1 in the longitudinal direction and The proportion of the width of the display screen of the mobile electronic device 1000 will decrease. The number of the rounded edges 13132 is 4, wherein the chordal edges 13131 and the rounded edges 13132 are adjacent to each other, and two ends of each of the chordal edges 13131 are connected to the rounded edges 13132, respectively. Both ends of the side 13132 are connected to the chord side 13131, respectively.

FIG. 3D shows an embodiment of the shrinking lens, and the shrinking lens is the first sub-lens 131. Of course, it can be understood that the lenses in other positions may also be the shrinking lens. An edge lens. In this example, the shrink lens includes a center region 1311 and an edge region 1312. The edge region 1312 is located at an edge position of the center region 1311, and is mainly used to connect to the edge mirror cylinder. Further, the central area 1311 includes an active area 13111 and a non-active area 13112, wherein the active area 13111 affects the operation of the photosensitive element 21 of the photosensitive component 20, thereby causing a final imaging effect. And the inactive area 13112 has almost no effect on the final imaging effect. In this example, the number of chord edges 13131 is two, the number of round edges 13132 is two, and the chord edges 13131 are located in the non-effective area 13112 of the center area 1311 of the shrink lens. That is to say, the reduction in size of the shrinking lens relative to the original round lens does not affect the final imaging effect.

Further, preferably, in the manufacturing process, each of the lenses is integrally formed, whether the lenses are round or the shrink lenses. Those skilled in the art can understand that the lens can be integrally injection-molded by a mold, and the manufacturing cost of the shrink-edge lens is reduced compared to the original circular lens. The chord edge 13131 of the hemming lens facilitates the positioning of the hemming lens and the corresponding hemming lens barrel during installation.

It can be understood that, the chord edge 13131 is located in the edge region 1312 of the lens, so that the quality of the camera module 1 has little or no impact. The center region 1311 of the frilled lens is unchanged from the center region 1311 of the original round lens, that is, the size reduction of the frilled lens is based on the edge region 1312. Reduced size. The central area 1311 of the lens corresponds to a photosensitive area of the photosensitive component 20 and is a main area for receiving light. The edge region 1312 of the lens is used to connect the first bearing member 111 or the second bearing member 121. This position needs to block light from passing through to avoid too much stray light from affecting the imaging quality.

By forming the chord edge 13131, the light intensity of the edge region 1312 of the shrinking lens will be weakened, which is conducive to reducing the formation of stray light and thus the imaging quality of the camera module 1, At the same time, the chord edge 13131 does not affect the central area 1311 during this process, thereby ensuring the imaging effect of the camera module 1.

According to the size of the first lens 131, the first bearing member 111 is designed and manufactured based on the size of the first lens 131. The first supporting member 111 may also be manufactured by an integral injection molding process. The first supporting member 111 may be a narrowed lens barrel.

Specifically, the shrinking lens barrel includes at least one chord edge portion 141 and at least one round edge portion 142, wherein the chord edge portion 141 corresponds to the chord edge 13131 of the shrink edge lens, and the round edge The portion 142 corresponds to the rounded edge 13132 of the shrink lens.

Preferably, the number, position, and shape of the chord edge portion 141 and the chord edge 13131 correspond to each other, and the number, position, and shape of the round edge portion 142 and the round edge 13132 correspond to each other. In this way, the size of the shrinking lens barrel relative to the original circular lens barrel can also be reduced, and the manufacturing cost of the shrinking lens barrel can also be reduced. It is worth mentioning that the shrinking lens barrel does not need to make a complete circle, so that the entire production difficulty can also be reduced.

Furthermore, the production of an optical lens needs to go through processes such as optical design, performance testing, and assembly. The entire optical system is a very sensitive and complex system. After the lenses are assembled on the first bearing member 111 or the second bearing member 121, the lenses and the first bearing member 111 or the second bearing member 121 are formed in batches. There is a difference in the performance or molding form of each batch. It is necessary to adjust the rotation angle of each lens in the first bearing member 111 or the second bearing member 121 in order to obtain the best performance. The optimal rotation angle of the lenses manufactured by different equipment or different batches will be different, so products manufactured in different batches need to be readjusted and then assembled according to the adjusted position.

For the beveled lens, once the beveled lens is applied to an integrated lens, because of the positioning function of the chord edge portion 141 and the chord edge 13131, the beveled lens and The installation angle of the shrinking lens barrel is fixed, which is disadvantageous for the final imaging quality.

In the present invention, the multi-group lens 10 is a split-type lens, and in this example, the beveled lens is located on the first bearing member 111 to form the first group lens 11. The first group lens 11 can be adjusted relative to the second group lens 12. That is, the first lens 131, which is a beveled lens, is opposite to the second lens 132, the third lens 133, the fourth lens 134, and the second lens 132 located in the second group lens 12. The position of the fifth lens 135 can be adjusted relatively. During this adjustment, the first group lens 11 and the second group lens 12 can obtain better imaging effects, which is beneficial to the camera mode. Group 1 final imaging quality.

S3. Connect the first group lens 11 and the second group lens 12 so that the relative distance between the first group lens 11 and the second group lens 12 in the optical axis direction is maintained. After adjusting the position.

It can be understood that arranging the first group lens 11 on the optical axis of the second group lens 12 does not mean that the first group lens 11 and the second group lens 12 are located Same optical axis. In fact, there may be a non-zero included angle between the axis of the first group lens 11 and the axis of the second group lens 12.

In some examples of the present invention, in the step S2, the relative positions of the first group lens 11 and the second group lens 12 are adjusted by means of rotation. For example, the first group lens 11 is rotated along the axis of the first group lens 11, and the second group lens 12 is rotated along the axis of the second group lens 12.

Pre-adjusted, moving the first group lens 11 and the second group lens 12 in a horizontal axis so that the first group lens 11 is located in the optical axis direction of the second group lens 12, and In this process, the positions of the first group lens 11 and the second group lens 12 can be maintained respectively, and then according to the first group lens 11 and the second group lens 12 to further adjust the relative positions of the first group lens 11 and the second group lens 12 at this time. There is a certain amount of space for adjusting the relative position between the two.

Finally, after determining the relative positions of the first group lens 11 and the second group lens 12 according to the actual shooting effect, the first group lens 11 and the second group can be fixed through a connection medium. The relative position of the group lens 12.

In the present invention, the connection process of the relative positions of the first group lens 11 and the second group lens 12 can be selected according to actual conditions. In an embodiment of the present invention, the first group lens 11 may be connected to the second group lens 12 through an adhesive process. In another embodiment of the present invention, the first group lens 11 may be connected to the second group lens 12 through a laser welding process. In another embodiment of the present invention, the first group lens 11 may be connected to the second group lens 12 through an ultrasonic welding process. In another embodiment of the invention. In addition to the above processes, other welding processes can also be selected.

The connection medium may also be another lens, such as a third group lens.

The connection medium may be one or more of UV glue, thermosetting glue, UV thermosetting glue, and epoxy resin.

More specifically, when pre-adjusting the positions of the first group lens 11 and the second group lens 12 separately, the following methods can be adopted:

First, the first group lens 11 and the second group lens 12 are respectively fixed to different working positions, and the tilt information of the first group lens 11 and the second group lens 12 are obtained respectively. , That is, tilt information. It can be obtained sequentially by laser height measurement or other methods. At this time, the first group lens 11 may not be maintained in the optical axis direction of the second group lens 12, that is, the first group The lens 11 and the second group lens 12 are not located on the same straight line in the height direction. Pre-adjust the positions of the first group lens 11 and the second group lens 12 separately according to the information of the first group lens 11 and the second group lens 12 obtained separately. After the related detection information of the first group lens 11 and the second group lens 12 can meet a certain requirement, moving the first group lens 11 and the second group lens 12 makes the first group lens 11 and the second group lens 12 The group lens 11 is located in the optical axis direction of the second group lens 12.

It may be keeping the position of the first group lens 11 fixed, and then moving the second group lens 12 until the first group lens 11 is located in the optical axis direction of the second group lens 12. It may also be that the first group lens 11 and the second group lens 12 are moved at the same time so that the first group lens 11 is located in the optical axis direction of the second group lens 12.

It can be understood that, in this process, the angles of the first group lens 11 and the second group lens 12 after adjustment are kept unchanged.

Further, in the process of pre-adjusting the positions of the first group lens 11 and the second group lens 12 separately, they can be respectively matched with a standard lens for adjustment. For example, the first group lens 11 is moved above a standard lens, so that the first group lens 11 and the standard lens can form a complete optical lens.

The second group lens 12 and the standard lens can form a complete optical lens. The actual imaging effect of the second group lens 12 and the standard lens can be used to adjust the second group lens 12 and the standard lens. position. In this way, pre-adjustment of the positions of the first group lens 11 and the second group lens 12 is achieved.

It can be understood, of course, that this is only an example, and other methods may be used to pre-adjust the positions of the first group lens 11 and the second group lens 12. The first group lens 11 and the second group lens 12 may also be located on the same optical axis and then adjusted simultaneously.

Further, according to another aspect of the present invention, the present invention provides a method for assembling a camera module 1, wherein the method for assembling the camera module 1 includes the following steps:

Further, during the adjustment process, a photosensitive component 20 that cooperates with imaging may be a standard photosensitive component 20 or a photosensitive component 20 directly mounted on the second group lens 12.

Further, FIG. 5A, FIG. 5B, and FIG. 5C illustrate an assembling method of a camera module 1 and another assembling method of the camera module 1 according to another embodiment of the present invention. In a preferred embodiment, the assembling method includes the following steps:

Step A: Provide a first group unit 100 and a second group unit 200, wherein the first group unit 100 includes the first group lens 11 and the second group unit 200 includes the The second group lens 12 and the photosensitive assembly 20, wherein the first group lens 11 and the second group lens 12 may optionally include at least one shrink lens. A color filter element 40 may be further installed between the second group lens 12 and the photosensitive component 20. The first group lens 11 includes at least one of the first lens and the first bearing member 111, and the second group lens 12 includes at least one of the second lens and the second bearing member 121. In this example, the number of the first lenses is one, and the first lens is a frilled lens. It can be understood that the number of the first lenses is not limited to one. In this example, the number of the second lenses is four, and each of the second lenses is a circular lens. It can be understood that the number of the second lenses is not limited to this, and the The second lens may also be a shrink lens.

Step B: Adjust the first group by arranging the first group unit 100 on the optical axis of the second group unit 200 to form an imageable optical system and based on the optical performance parameters of the real shot The relative positions of the group unit 100 and the second group unit 200.

For the assembled camera module 1, there will be a desired imaging surface, which can be referred to as a target surface. In some cases, the target surface is a plane. For example, when the photosensitive surface 211 of the photosensitive element 21 of the camera module 1 is a plane, in order to achieve imaging quality, the desired imaging plane of the multi-group lens 10 is also a plane, that is, The target surface is a plane. In other cases, the target surface may be a concave or convex or wavy curved surface. For example, the photosensitive surface 211 of the photosensitive element 21 of the camera module 1 is a wavy curved surface. The desired imaging surface of the multi-group lens 10 is also a flat surface. The camera module 1 The photosensitive surface 211 of the photosensitive element 21 is a convex surface, so the desired imaging surface of the multi-group lens 10 is also a convex surface.

Further, in this example, it can be identified whether the real-time imaging surface and the target surface match based on the image output by the photosensitive element 21. The shape of the photosensitive surface 211 of the photosensitive element 21 is the desired shape of the imaging surface. That is to say, the photosensitive surface 211 is the target surface, so the image received through the photosensitive surface 211 of the photosensitive element 21 has already hidden the field curvature information of the target surface. Therefore, in order to provide imaging quality, the field curvature of the image output by the photosensitive element 21 should be as small as possible. In this case, the imaging surface formed by the optical system imaging matches the target surface, so that a better imaging quality can be obtained.

In this way, the problem that the hemming lens cannot be adjusted during assembly can be solved, thereby helping to reduce the size of the camera module 1 on the one hand, and improving the Product quality of the camera module 1.
