Technical Field

The invention relates to the technical field of camera shooting, in particular to a multi-camera module and an assembling method thereof.

Background

As shown in fig. 5, a multi-camera module includes a support 20 and a plurality of single camera modules 12, the support 20 is provided with a plurality of mounting through holes 22 for mounting the plurality of single camera modules 12, a distance between an outer wall of the single camera module 12 and an inner wall of the mounting through hole 22 of the support 20 is equal to 0.15mm, and the single camera module 12 and the support 20 can be assembled by adopting an automatic assembling manner of a machine.

When the single camera module 12 and the bracket 20 are placed to complete the assembly, the eccentric size of the lens and the eccentric size of the bracket need to meet the requirement of +/-0.12 mm. Specifically, as shown in fig. 6, the preset distance between two adjacent optical axes 30 in the first direction 10a is L, the preset distance between two optical axes 30 in the second direction 10b is 0, and after the assembly is completed, the actual distance between two adjacent optical axes 30 in the first direction 10a is L ± 0.12mm, and the actual distance between two optical axes 30 in the second direction 10b is 0 ± 0.12 mm. The preset distance between any optical axis 30 and the outer side wall of the bracket 20 is R, and after the assembly is completed, the actual distance between any optical axis 30 and the outer side wall of the bracket 20 is R ± 0.12 mm.

As shown in fig. 1, in a multi-camera module 10 according to an embodiment of the present invention, the multi-camera module 10 can be applied to a mobile terminal. The mobile terminal includes a terminal body (not shown) and a camera module 10 disposed on the terminal body. The mobile terminal can be a portable mobile terminal such as a smart phone and a tablet computer.

The multi-camera module 10 includes a plurality of single camera modules 12. The multi-camera module 10 is more excellent in functions such as night photographing, optical anti-shake, and lossless zoom than the single-camera module 12. The plurality of single camera modules 12 may be arranged in any regular shape or any irregular shape. Therefore, the mobile terminal with different structures can be satisfied.

As shown in fig. 1, a plurality of single camera modules 12 are arranged in a straight line (linear type). Specifically, in the embodiment shown in fig. 1, the multi-camera module 10 includes three single-camera modules 12, that is, the multi-camera module 10 is a three-camera module.

As shown in fig. 2, the plurality of single camera modules 12 are arranged in an L shape (right-angle shape). Specifically, in the embodiment shown in fig. 2, the multi-camera module 10 includes three single-camera modules 12, that is, the multi-camera module 10 is a three-camera module.

The multi-camera modules 10 shown in fig. 1-4 each include a common-substrate dual-camera module 14. The common-substrate type dual-camera module 14 includes two single-camera modules 12, and the substrates of the two single-camera modules 12 are combined into one substrate. In this way, the two single camera modules 12 of the common-substrate type dual camera module 14 can share one flexible circuit board 16 connected to the substrate. Each of the other single camera modules 12 has a flexible circuit board 16 connected to the substrate.

In the multi-camera module 10 shown in fig. 1 to 4, a plurality of single camera modules 12 are assembled together by one bracket 20, that is, a plurality of single camera modules 12 share one bracket 20.

As shown in fig. 5, the bracket 20 is provided with a plurality of mounting through holes 22, and the plurality of single camera modules 12 are respectively inserted into the plurality of mounting through holes 22. One end of the single camera module 12 having the substrate 100 may close one end of the mounting through hole 22, and the other end of the single camera module 12 extends out of the mounting through hole 22. Wherein, one end of the single camera module 12 having the substrate 100 can be accommodated in the mounting through hole 22, and the substrate 100 is located in the bracket 20; an end surface of one open end of the holder 20 may be provided on the substrate 100, in which case the substrate 100 is located outside the holder 20.

The multi-camera module 10 has a plurality of optical axes 30. It is preferable that the optical axes 30 of the multi-camera module 10 are parallel to each other. In practical products, the optical axes 30 of the multi-camera module 10 are difficult to be strictly parallel, and an optical axis angle exists between the optical axes 30. And the actual distance between two adjacent optical axes 30 is hardly the same as the preset distance, a lens eccentricity dimension exists between the optical axes 30, the actual distance between any one optical axis 30 and the outer side wall of the bracket 20 is hardly the same as the preset distance, and a bracket eccentricity dimension exists between the optical axis 30 and the bracket 20.

In one embodiment, as shown in fig. 5 and fig. 6, the included angle between the optical axes needs to be less than 0.12 °, the preset distance between two adjacent optical axes 30 in the first direction 10a is L, and the preset distance between two optical axes 30 in the second direction 10b is 0, after the assembly is completed, the actual distance between two adjacent optical axes 30 in the first direction 10a is L ± 0.12mm, and the actual distance between two optical axes 30 in the second direction 10b is 0 ± 0.12 mm. The preset distance between any optical axis 30 and the outer side wall of the bracket 20 is R, and after the assembly is completed, the actual distance between any optical axis 30 and the outer side wall of the bracket 20 is R ± 0.12 mm.

Taking the view angle shown in fig. 6 as an example, during the AA correction (correction of the optical axis 30), the single camera module 12 can be moved in six directions, i.e., up and down (Y axis), left and right (X axis), and front and back (Z axis), to adjust the positions of the two optical axes 30, thereby adjusting the lens eccentricity; the bracket 20 can be moved in six directions, i.e., up and down (Y axis), left and right (X axis), and front and back (Z axis), to adjust the positions of the bracket 20 and the optical axis 30, thereby adjusting the eccentric size of the bracket; the single camera module 12 can be moved in six directions, i.e., up and down (Y-axis), left and right (X-axis), and front and back (Z-axis), and rotated in the Y-axis, X-axis, and Z-axis directions in the forward or reverse directions to adjust the optical axis angle between the two optical axes 30.

In one embodiment, as shown in fig. 7, an adhesive layer 18 is disposed between two adjacent single camera modules 12, that is, two adjacent single camera modules 12 are fixedly connected by the adhesive layer 18, and in this case, the bracket 20 may be omitted. When the multi-camera module 10 is manufactured, glue can be drawn on the single-camera module 12 by adopting a glue drawing process, and the glue is cured to form the bonding layer 18.

In one embodiment, as shown in fig. 7, the multi-camera module 10 may be formed by combining the bracket 20 and the adhesive layer 18.

In one embodiment, as shown in fig. 7, the multi-camera module 10 includes at least one single-camera module 12 and at least one common-substrate dual-camera module 14, and the two single-camera modules 12 of the common-substrate dual-camera module 14 are assembled together by a bracket 20. Set up tie coat 18 between the support 20 of single camera module 12 and the two camera modules of the same base plate formula 14, set up tie coat 18 between two adjacent single camera modules 12 (for example, a many camera modules of a font that the two camera modules of the same base plate formula 14 and two single camera modules 12 constitute), also the single camera module 12 and the two camera modules of the same base plate formula 14 connect into a whole through tie coat 18. In the present embodiment, there is one single camera module 12 and one substrate-shared dual camera module 14, i.e. the multi-camera module 10 is a three-camera module.

As shown in fig. 8, the common-substrate dual-camera module 14 is one of the dual-camera modules. As shown in fig. 9, the dual-camera module can also be a split dual-camera module 19, the split dual-camera module 19 includes two single-camera modules 12, and a bonding layer 18 can be arranged between the two single-camera modules 12 and assembled together through the bonding layer 18. The split type dual-camera module 19 has two flexible circuit boards 16.

The double-camera module is divided into a common-substrate double-camera module 14 and a split double-camera module 19, the common-substrate double-camera module 14 can be electrically connected with an external circuit through a flexible circuit board 16, and when the common-substrate double-camera module 14 is electrically connected with the external circuit through a flexible circuit board 16, an electrical connection step can be omitted when the electrical connection is performed.

Every single camera module 12 all has optical axis 30, and every two camera modules all have two optical axes 30, and the quantity of optical axis 30 is irrelevant with the form of two camera modules, also no matter the two camera modules are split type two camera modules or share the two camera modules 14 of base plate formula, and two camera modules all have two optical axes 30.

Because optical elements such as the photosensitive chip of the common-substrate type double-camera module 14 are located on the same substrate, the flatness is easier to control, so that the optical axis included angle between two optical axes 30 of the common-substrate type double-camera module 14 and the eccentric size of a lens between the two optical axes 30 are easier to control.

Specifically, as shown in fig. 7, the multi-camera module 10 includes a single camera module 12 and a dual camera module 14. When the multi-camera module 10 is in an institutional state, on the basis of the double-camera module 14, the single-camera module 12 and the double-camera module 14 can be glued and fixed to form a three-camera module in an AA (optical axis 30 correction) mode, and the requirements of specifications such as the lens eccentric size and the optical axis included angle of the single-camera module 12 and the double-camera module 14 are met.

In one embodiment, the lens eccentricity size has an error range of ± 0.10 mm, as shown in fig. 7. For example, the plurality of single camera modules 12 are arranged in a straight line along the first direction 10a, the predetermined distance between the two optical axes 30 in the first direction 10a is L, the distance between the two optical axes 30 in the first direction 10a is controlled to be L ± 0.10 mm, and the distance between the two optical axes 30 in the second direction 10b is controlled to be 0 ± 0.10 mm in the AA calibration process. Wherein the first direction 10a is perpendicular to the second direction 10 b. Taking the view angle shown in fig. 7 as an example, the single camera module 12 can be moved in six directions, i.e., up and down (Y axis), left and right (X axis), and front and back (Z axis), to adjust the distance between the two optical axes 30.

In one embodiment, as shown in FIG. 10, the included angle of the optical axes needs to be less than 0.12. During the AA correction, the single camera module 12 can be moved in six directions, i.e., up and down (Y axis), left and right (X axis), and front and back (Z axis), and rotated in the Y axis, X axis, and Z axis directions in the forward or reverse directions to adjust the included angle between the two optical axes 30.

Two assembly schemes of the multi-camera module 10, that is, two AA correction (optical axis 30 correction) schemes, will be described in detail below.

The first scheme is as follows: automatic assembling machine

Step S710, a first automatic machine is used to capture the first single camera module 12, and the first single camera module 12 is placed on the assembly table (carrier), and the first automatic machine identifies the position of the first single camera module 12.

Step S720, a second automatic machine is used to capture the second single camera module 12, and the second single camera module 12 is placed according to the position of the first single camera module 12, so that the first single camera module 12 and the second single camera module 12 meet the requirements of the optical axis included angle and the lens eccentric size.

The step S720 is repeated until the plurality of single camera modules 12 are all placed on the assembly table (carrier). That is, the third automatic machine station picks up the third single camera module, and places the third single camera module 12 according to the position of the first single camera module 12, so that the first single camera module 12 and the third single camera module 12 meet the requirements of the optical axis included angle and the eccentric size of the lens. Of course, if the second robot identifies the position of the second single camera module 12, the third robot can also capture the third single camera module and place the third single camera module 12 according to the position of the second single camera module 12. The fourth single camera module, the fifth single camera module and other more single camera modules are arranged in the same way, and are not repeated here.

Step S730, the bracket 20 is grabbed by using the bracket assembly machine, and after the centers of the installation through holes 22 of the bracket 20 are aligned with the optical axes 30 of the single camera modules 12, the single camera modules 12 are sleeved with the bracket 20.

In one particular embodiment, as shown in fig. 11-13:

step S710a, as shown in fig. 11, a first robot is used to capture the common-substrate dual camera module 14 and place the common-substrate dual camera module 14 on an assembly table (carrier), and the first robot identifies the position of the common-substrate dual camera module 14.

Step S720a, as shown in fig. 12, a second robot is used to pick up the single camera module 12, and place the picked-up single camera module 12 according to the position of one single camera module 12 of the common substrate type dual camera modules 14, so that the picked-up single camera module 12 and one single camera module 12 of the common substrate type dual camera modules 14 satisfy the requirements of the optical axis angle and the lens eccentricity size.

Step S730a, as shown in fig. 13, the bracket 20 is grasped by the bracket assembly machine, and after the centers of the installation through holes 22 of the bracket 20 are aligned with the optical axes 30 of the single camera modules 12, the bracket 20 is fitted over the single camera modules 12.

Above-mentioned automatic equipment mode of board, the degree of difficulty of putting between single camera module and the single camera module is great, and the counterpoint degree of difficulty of support and single camera module is also great, leads to the inefficiency of above-mentioned automatic equipment mode of board, needs more automatic board moreover, needs great equipment space moreover.

In addition, as shown in fig. 5, in the multi-camera module 10 automatically assembled by using the above-mentioned machine, the distance between the outer wall of the single camera module 12 and the inner wall of the installation through hole 22 of the bracket 20 is greater than or equal to 0.15mm, that is, the single camera module 12 and the bracket 20 are not tightly assembled, which results in a large size of the multi-camera module 10.

In one particular embodiment, as shown in fig. 5, the spacing between the outer wall of the single camera module 12 and the inner wall of the mounting through hole 22 of the bracket 20 is equal to 0.15 mm.

Scheme II: jig assembly

Step S810, providing a plurality of jigs and a plurality of single camera modules 12, and fixing the plurality of single camera modules 12 on the plurality of jigs respectively.

Step S820, providing a bracket, wherein the bracket is provided with a plurality of mounting through holes, the plurality of mounting through holes respectively correspond to the plurality of single camera modules, and the bracket is sequentially sleeved on the plurality of single camera modules. Wherein, the support overlaps in proper order and locates a plurality of single modules of making a video recording on, for the support overlaps simultaneously and locates a plurality of single modules of making a video recording, can reduce the counterpoint of support and put the degree of difficulty, improves the packaging efficiency. .

Step S830, remove the jig.

In the assembly of the jig, the at least one single camera module on each jig is in close fit with the corresponding mounting through hole. There are two cases as follows:

(1) if single tool corresponds with single module 12 of making a video recording, then, a plurality of single modules of making a video recording equally divide the cooperation of installing the through-hole rather than corresponding and be close-fitting fit.

(2) If there is single tool and at least two singly to make a video recording module 12 and correspond, at this moment, a plurality of singly make a video recording modules can equally divide and do not be the close-fitting fit with the cooperation of the installation through-hole that corresponds with it, also can have in a plurality of singly make a video recording modules that the cooperation of the installation through-hole that corresponds rather than the close-fitting fit singly makes a video recording module.
