Description

Optical lens, camera module, electronic equipment and assembling method of optical lens

Technical Field

The present invention relates to an optical imaging device, and more particularly, to an optical lens, an image capturing module, an electronic apparatus, and a method for assembling an optical lens.

Background

In recent years, small camera modules equipped with imaging elements such as CCD (Charge Coupled Device) type image sensors or CMOS (Complementary Metal-Oxide Semiconductor) type image sensors have been widely used in the field of portable electronic devices (e.g., smart phones), and the market has increasingly demanded higher image quality and smaller size for camera modules equipped in portable electronic devices. The existing camera module includes a photosensitive component and an optical lens disposed on the photosensitive component, where the optical lens generally includes 3 to 5 lenses sequentially arranged along an optical axis direction, and incident light can be converged and then reach an image sensor of the photosensitive component to form an image when passing through the lenses. For the zoom camera module, the optical lens needs to be installed in a driver (e.g. a voice coil motor) in a driving manner, and the driver drives the optical lens to move as a whole to achieve focusing of the camera module, although the zoom camera module has the advantage of better imaging quality, the disadvantages are: firstly, the size of the camera module is increased due to the arrangement of the driver, so that the camera module cannot be applied to the front side of the portable electronic equipment pursuing lightness and thinness, and therefore, the front camera modules of the portable electronic equipment in the market adopt a fixed-focus camera module scheme, so that the imaging capability of the front camera module is limited; secondly, the actuator drives the optical lens to move integrally to focus the camera module, so that on one hand, the total optical length of the optical lens is changed, which is not beneficial to the miniaturization of the camera module, and on the other hand, when the camera module is configured in the portable electronic device, especially when the camera module is used as a front camera module of the portable electronic device, a space for the movement of the optical lens needs to be reserved inside the portable electronic device, and further, the thickness of the portable electronic device cannot be reduced.

Fig. 1A to 1I illustrate an assembly process of an optical lens 100 according to a preferred embodiment of the present invention, and fig. 2A and 2B illustrate an exploded state of the optical lens 100.

The optical lens 100 includes an object-side lens group 10, a focusing lens group 20, an image-side lens group 30 and a housing 40, wherein the object-side lens group 10 is attached to the housing 40 and located outside the housing 40 to allow the optical lens 100 to adopt a "small-head" design, wherein the focusing lens group 20 is drivably disposed inside the housing 40, wherein the image-side lens group 30 is fixedly disposed inside the housing 40, and the object-side lens group 10, the focusing lens group 20 and the image-side lens group 30 are coaxially disposed, such that the object-side lens group 10 and the housing 40 form a substantial appearance of the optical lens 100 to allow the optical lens 100 to have a built-in focusing function. When the focus lens group 20 is driven to move along the optical axis direction of the optical lens 100, the focal position of the optical lens 100 can be adjusted to achieve focusing.

Specifically, the housing 40 further includes a main housing 41 and a bottom housing 42 mounted on the bottom side of the main housing 41, and the housing 40 has a housing space 43 formed between the main housing 41 and the bottom housing 42, wherein the main housing 41 forms a top central opening 411 communicating with the housing space 43, and the bottom housing 42 forms a bottom central opening 421 communicating with the housing space 43.

The object side lens group 10 is attached to the outer side of the main housing 41 of the housing 40, and the top central opening 411 of the main housing 41 corresponds to the object side lens group 10, so that incident light passing through the object side lens group 10 is allowed to enter the inside of the housing 40 through the top central opening 411 of the main housing 41.

Further, the object-side lens group 10 includes an object-side lens barrel 11 and at least one object-side lens 12 mounted on the object-side lens barrel 11, wherein the object-side lens barrel 11 is mounted on an outer side of the main housing 41, and the top central opening 411 of the main housing 41 corresponds to the object-side lens 12, so that the object-side lens group 10 is mounted on the housing 40. Preferably, the bottom side of the object-side barrel 11 is attached to the outer side of the main housing 41, for example, the bottom side of the object-side barrel 11 may be attached to the outer side of the main housing 41 by glue, and in this case, the glue may compensate the inclination of the object-side lens group 10.

Preferably, the main housing 41 has at least one flange 412 for defining the top central opening 411 of the main housing 41, wherein the object-side lens barrel 11 is attached to the flange 412 of the main housing 41, so that the position of the object-side lens group 10 is raised by the flange 412.

Further, the main housing 41 has a fitting passage 413 defined by the flange 412 to allow the fitting passage 413 to communicate with the top central opening 411 and the housing space 43, wherein the focus lens group 20 is allowed to be fitted to the housing space 43 of the housing 40 through the fitting passage 413 of the main housing 41.

It is understood that, in order to ensure that the focusing lens group 20 is smoothly assembled in the housing space 43 of the housing 40 through the assembling passage 413 of the main housing 41, the height dimension of the assembling passage 413 of the main housing 41 is slightly larger than the thickness dimension of the focusing lens group 20, so that the main housing 41 can be prevented from scratching the focusing lens group 20 during the process of assembling the focusing lens group 20 in the housing space 43 of the housing 40 through the assembling passage 413 of the main housing 41. It is also understood that the height dimension of the fitting passage 413 of the main housing 41 is limited by the height dimension of the flange 412, and therefore, the design of the height dimension of the flange 412 of the main housing 41 is determined by the thickness dimension of the focus lens group 20.

Preferably, the number of the flanges 412 of the main housing 41 is two, and the two flanges are oppositely disposed at two sides of the top central opening 411, so that the main housing 41 can form two opposite fitting channels 413 between the two flanges 412.

The focusing lens group 20 is arranged in the housing space 43 of the housing 40 in a suspension manner, so as to allow the housing 40 to surround the focusing lens group 20 and protect the focusing lens group 20. It should be noted that the specific implementation structure of the focusing lens group 20 being drivably disposed in the housing space 43 of the housing 40 in a floating manner will be further disclosed in the following description.

Preferably, the diameter of the object side lens group 10 is larger than that of the focusing lens group 20, so that the object side lens barrel 11 of the object side lens group 10 can be attached to the flange 412 of the main housing 41 on the basis of ensuring that the focusing lens group 20 is allowed to be assembled in the housing space 43 of the housing 40 through the assembling passage 413 of the main housing 41.

The image side lens group 30 is mounted to the main housing 41 to fixedly dispose the image side lens group 30 in the housing space 43 of the housing 40. Specifically, referring to fig. 2A and 2B, the main housing 41 has at least one mounting arm 414 located in the housing space 43 of the housing 40, wherein the image side lens group 30 is mounted to the main housing 41 by being mounted to the mounting arm 414. Alternatively, in another example of the optical lens 100 of the present invention, the image side lens group 30 may be mounted on the bottom case 42 so that the bottom case 42 holds the image side lens group 30 in the case space 43 of the housing 40.

Further, the image side lens group 30 includes an image side lens barrel 31 and at least one image side lens 32 mounted on the image side lens barrel 31, wherein the image side lens barrel 31 is mounted on the mounting arm 414 of the main housing 41 to fixedly dispose the image side lens group 30 in the housing space 43 of the housing 40.

It should be noted that the manner of attaching the image side lens barrel 31 of the image side lens group 30 and the attachment arm 414 of the main housing 41 is not limited to the optical lens 100 of the present invention. For example, in this specific example of the optical lens 100 according to the present invention, referring to fig. 2A and 2B, the mounting arm 414 of the main housing 41 has at least one locking groove 4141, and accordingly, the image side lens barrel 31 of the image side lens group 30 has at least one locking protrusion 311, wherein the locking protrusion 311 of the image side lens barrel 31 is locked into the locking groove 4141 of the mounting arm 414 to mount the image side lens group 30 on the main housing 41. Alternatively, in another specific example of the optical lens 100 of the present invention, the clamping groove 4141 may be provided in the image side lens barrel 31, and correspondingly, the clamping protrusion 311 may be provided in the mounting arm 414, so that the clamping protrusion 311 of the mounting arm 414 can be clamped into the clamping groove 4141 of the image side lens barrel 31 to mount the image side lens group 30 on the main housing 41.

With continued reference to fig. 1A to fig. 2B, the optical lens 100 further includes a driving unit 50 for suspending and holding the focusing lens group 20 in the housing space 43 of the housing 40 and for driving the focusing lens group 20 to move along the optical axis of the optical lens 100 to achieve focusing.

Specifically, the driving unit 50 includes a fixed portion 51, a carrying portion 52 and a driving portion 53 for driving the carrying portion 52 to move relative to the fixed portion 51 along the optical axis direction of the optical lens 100, wherein the fixed portion 51 is fixedly disposed on the housing 40, wherein the carrying portion 52 has a carrying outer side 5201 and a carrying inner side 5202 corresponding to the carrying outer side 5201, the carrying outer side 5201 of the carrying portion 52 extends outward to a position adjacent to the fixed portion 51, and the carrying inner side 5202 of the carrying portion 52 extends inward above the image side lens group 30, so as to allow the focusing lens group 20 mounted on the carrying inner side 5202 of the carrying portion 52 to be held above the image side lens group 30 in a floating manner. When the driving part 53 drives the bearing part 52 to move, the bearing part 52 drives the focusing lens group 20 to move synchronously to realize focusing.

In this specific example of the optical lens 100 shown in fig. 1A to 2B, the fixing portion 51 is fixedly provided to the main housing 41 of the housing 40. Alternatively, in other examples of the optical lens 100 of the present invention, the fixing portion 51 may be fixedly disposed on the bottom housing 42 of the outer housing 40, or the fixing portion 51 and the main housing 41 are of an integrated structure, or the fixing portion 51 and the bottom housing 42 are of an integrated structure.

With continued reference to fig. 1A to fig. 2B, the driving unit 50 further includes at least one elastic sheet 54, wherein an outer side of the elastic sheet 54 extends outward to be connected to the fixing portion 51, and an inner side of the elastic sheet 54 extends inward to be connected to the carrying portion 52, so that when the driving portion 53 does not drive the carrying portion 52, the fixing portion 51, the carrying portion 52 and the elastic sheet 54 make the focusing lens group 20 in a relatively stable state, and when the driving portion 53 drives the carrying portion 52, the elastic sheet 54 can be deformed.

It should be noted that the number of the elastic pieces 54 is not limited in the optical lens 100 of the present invention, for example, the number of the elastic pieces 54 may be one, the outer side and the inner side of the elastic pieces 54 are respectively connected to the upper side of the fixing portion 51 and the upper side of the carrying portion 52, or the inner side and the outer side of the elastic pieces 54 are respectively connected to the lower side of the fixing portion 51 and the lower side of the carrying portion 52; or, the number of the elastic pieces 54 is two, the outer side and the inner side of one of the elastic pieces 54 are respectively connected to the upper side of the fixing portion 51 and the upper side of the carrying portion 52, and the outer side and the inner side of the other elastic piece 54 are respectively connected to the lower side of the fixing portion 51 and the lower side of the carrying portion 52.

Alternatively, in other examples of the optical lens 100 of the present invention, the driving unit 50 may replace the elastic sheet 54 with at least one ball, so that the focus lens group 20 is held in the housing space 43 of the housing 40 in a floating manner. Specifically, the balls are held between the fixing portion 51 and the bearing portion 52, when the bearing portion 52 is not driven by the driving portion 53, the fixing portion 51, the bearing portion 52 and the balls make the focus lens group 20 in a relatively stable state, and when the bearing portion 52 is driven by the driving portion 53, the balls can roll, so that the movement of the bearing portion 52 is smoother. In particular, the fixing portion 51 is provided with at least one first recess for receiving a portion of the ball, and correspondingly, the bearing portion 52 is provided with at least one second recess for receiving a portion of the ball, so as to reliably retain the ball between the fixing portion 51 and the bearing portion 52 and avoid direct contact between the bearing portion 52 and the fixing portion 51.

With continued reference to fig. 1A to 2B, the driving portion 53 includes at least one magnet 531 and at least one coil 532, wherein the magnet 531 is disposed on the fixed portion 51, the coil 532 is disposed on the carrying outer side 5201 of the carrying portion 52, and the position of the magnet 531 corresponds to the position of the coil 532, such that when the coil 532 is powered, the magnetic field generated by the coil 532 interacts with the magnet 531 to drive the carrying portion 52 to move, thereby driving the focusing lens group 20 to move for focusing.

Preferably, the fixing portion 51 has a ring shape and is located outside the focus lens group 20, wherein the driving portion 53 includes two magnets 531, and the two magnets 531 are disposed at opposite sides of the fixing portion 51 in an opposing manner, so that the two magnets 531 can be held outside the focus lens group 20 in an opposing manner. The outer bearing side 5201 of the bearing part 52 is annular and located outside the focus lens group 20, wherein the driving part 53 includes a coil 532 which is diffracted at the outer bearing side 5201 of the bearing part 52, so that the coil 532 is annular and located outside the focus lens group 20. With such a structure, when the coil 532 is powered, the magnetic field generated by the annular coil 532 interacts with the two oppositely arranged magnets 531 to drive the bearing part 52 uniformly, so as to avoid the bearing part 52 from tilting during the movement, thereby ensuring the optical performance of the optical lens 100.

Preferably, the bearing portion 52 forms an annular winding slot 5203 on the bearing outer side 5201, wherein the coil 532 is wound around the winding slot 5203 of the bearing portion 52, so as to ensure that the coil 532 is disposed on the bearing outer side 5201 of the bearing portion 52. Moreover, the coil 532 is allowed to wind around the winding slot 5203 of the bearing part 52, so that the coil 532 is prevented from protruding the side wall of the bearing outer side 5201 of the bearing part 52, which is advantageous for reducing the length and width dimensions of the optical lens 100.

Alternatively, in another example of the optical lens 100 according to the present invention, the driving portion 53 may include three or more magnets 531, for example, the driving portion 53 may include four magnets 531, and the magnets 531 are disposed on the fixing portion 51 in a manner that they are spaced apart from each other and surround the focus lens group 20.

It should be noted that the assembly manner of the magnet 531 and the fixing portion 51 of the driving portion 53 is not limited in the optical lens 100 of the present invention, for example, the magnet 531 may be adhered to the inner wall of the fixing portion 51 to fixedly dispose the magnet 531 on the fixing portion 51, or the fixing portion 51 may be provided with at least one fitting groove 511 for fitting the magnet 531 to fixedly dispose the magnet 531 on the fixing portion 51.

Preferably, with continued reference to fig. 1A to 2B, the fixed portion 51 surrounds the image side lens group 30, so that the two magnets 531 are disposed oppositely on two opposite sides of the image side lens group 30, and accordingly, the height position of the carrying outer side 5201 of the carrying portion 52 is lower than the height position of the carrying inner side 5202, so that the carrying portion 52 can wind the coil 532 wound around the carrying outer side 5201 of the carrying portion 52 around the image side lens group 30 on the basis of carrying the focus lens group 20 on the upper side of the image side lens group 30, in such a way that the coil 532 of the driving unit 50 can be lowered to reduce the height dimension of the optical lens 100.

Specifically, the carrying portion 52 further includes a driven ring 521, a carrying ring 522 and at least one extending arm 523 extending between the driven ring 521 and the carrying ring 522, wherein the driven ring 521 forms the carrying outer side 5201 of the carrying portion 52 to allow the coil 532 to be disposed around the driven ring 521, wherein the carrying ring 522 forms the carrying inner side 5202 of the carrying portion 52 for mounting the focus lens group 20, wherein at least a portion of the extending arm 523 is inclined to allow the height position of the carrying outer side 5201 of the carrying portion 52 to be lower than the height position of the carrying inner side 5202.

Preferably, the extension arm 523 of the carrying part 52 corresponds to the assembly channel 413 of the main housing 41, and when the carrying part 52 is driven, at least a part of the extension arm 523 of the carrying part 52 can move to the assembly channel 413 of the main housing 41 to prevent the extension arm 523 from touching the main housing 41, so as to increase the stroke range of the carrying part 52 and the stroke range of the focus lens group 20. In other words, the mounting channel 413 of the main housing 41 can form an escape space to escape the extension arm 523 of the carrying part 52, thereby increasing the stroke range of the focus lens group 20. Preferably, the width of the assembling channel 413 of the main housing 41 is slightly larger than the width of the extension arm 523 of the bearing part 52, so as to avoid the extension arm 523 from scratching the main housing 41 and ensure the reliability of the optical lens 100.

Preferably, the main housing 41 further has at least one movable channel 415 communicating with opposite sides of the mounting arm 414, wherein the extension arm 523 of the carrying part 52 is movably held in the movable channel 415 of the main housing 41, in such a way that the driven ring 521 and the carrying ring 522 of the carrying part 52 can be respectively held on opposite sides of the mounting arm 414. Preferably, the width of the movable channel 415 of the main casing 41 is greater than the width of the extension arm 523 of the bearing part 52, so that when the bearing part 52 is driven by the driving part 53, the extension arm 523 can be prevented from scratching the mounting arm 414 of the main casing 41.

More specifically, the carrying part 52 includes two extension arms 523, which connect the driven ring 521 and the carrying ring 522 in a mutually symmetrical manner, and accordingly, the main housing 41 has two moving channels 415, wherein each extension arm 523 of the carrying part 52 is movably mounted to each moving channel 415 of the main housing 41.

With continued reference to fig. 1A to 2B, the extension arm 523 of the carrier 52 has a lower horizontal extension portion 5231, an upper horizontal extension portion 5232 and an inclined extension portion 5233, wherein the lower horizontal extension portion 5231 integrally extends inward from the driven ring 521, the upper horizontal extension portion 5232 integrally extends outward from the carrier ring 522, and opposite ends of the inclined extension portion 5233 respectively extend to and are connected to the lower horizontal extension portion 5231 and the upper horizontal extension portion 5232, such that the height position of the driven ring 521 of the carrier 52 is lower than the height position of the carrier ring 522 to sink the coil 532 of the driver 53, so as to facilitate reducing the height dimension of the optical lens 100.

In an alternative example of the optical lens 100 of the present invention, the extension arm 523 of the mount 52 is composed of the lower horizontally extending portion 5231 and the inclined extending portion 5233, wherein the lower horizontally extending portion 5231 integrally extends inward from the driven ring 521, and opposite ends of the inclined extending portion 5233 extend to and are connected to the lower horizontally extending portion 5231 and the mount ring 522, respectively.

In another alternative example of the optical lens 100 of the present invention, the extension arm 523 of the carrier 52 is composed of the upper horizontally extending portion 5232 and the inclined extending portion 5233, wherein the upper horizontally extending portion 5232 integrally extends outward from the carrier ring 522, and opposite ends of the inclined extending portion 5233 extend to and are connected to the upper horizontally extending portion 5232 and the driven ring 521, respectively.

In another alternative example of the optical lens 100 of the present invention, the extension arm 523 of the bearing part 52 is inclined as a whole, that is, opposite ends of the extension arm 523 extend to and are connected to the driven ring 521 and the bearing ring 522, respectively, in such a manner that the extension arm 523 is inclined as a whole.

Further, the driving unit 50 includes a carrier 55, wherein the carrier 55 surrounds the focus lens group 20, and the carrier 55 is mounted on the carrier ring 522 of the carrier 52, and the focus lens group 20 is fixedly mounted on the carrier 52 by the carrier 55.

Further, the optical lens 100 includes a cover 60, wherein a bottom side of the cover 60 extends to and is attached to the main housing 41, and an inner side of the cover 60 extends to and is attached to the object-side barrel 11 of the object-side lens group 10, so as to allow the cover 60 to close the mounting passage 413 of the main housing 41, thereby preventing contaminants such as dust from entering the housing space 43 of the housing 40 through the mounting passage 413 of the main housing 41 to contaminate the focus lens group 20 and the image-side lens group 30.

Fig. 1A to 1I illustrate an assembling process of the optical lens 100, which includes the following stages.

Referring to fig. 1A, a standard lens group 300 is pre-fixed on the carrying ring 522 of the carrying portion 52.

Referring to fig. 1B, the carrier ring 52 and the fixing portion 51 are connected by the elastic sheet 54, wherein the fixing portion 51 is mounted on the main housing 41 of the housing 40, so that the carrier ring 52 and the standard lens group 300 are held in the housing space 43 of the housing 40, and the standard lens group 300 corresponds to the assembling passage 413 of the main housing 41.

Referring to fig. 1C, the image side lens group 30 is mounted in the housing space 43 of the housing 40.

Referring to fig. 1D, the object-side lens group 10 is mounted on the flange 412 of the main housing 41, and at this time, the object-side lens group 10, the standard lens group 300 and the image-side lens group 30 are substantially coaxial.

Next, the object side lens group 10, the standard lens group 300, and the image side lens group 30 are calibrated in accordance with sensitivities of the object side lens group 10, the standard lens group 300, and the image side lens group 30 in the entire optical lens 100.

It should be noted that the relationship among the object-side lens group 10, the standard lens group 300, and the image-side lens group 30 is: (1) The Z-direction gap mainly affects the curvature of field of the optical lens 100; (2) The position in the XY direction mainly affects the peak value of the optical lens 100; (3) The tilt between the upper lens group 10, the standard lens group 300, and the lower lens group 30 mainly affects the tilt, astigmatism, and the like of the optical lens 100. Therefore, when the optical lens 100 is designed, it is necessary to balance the sensitivity of the overall optical performance of the optical lens 100, that is, a specific lens or a specific lens group is not so sensitive due to the relationship among the object-side lens group 10, the standard lens group 300, and the image-side lens group 30 that the overall optical performance of the optical lens 100 is degraded due to the high sensitivity of the lens or the lens group. However, due to different actions and powers of the lenses, there are lens groups with sensitivity gradually increasing from low to high, and in general, the sensitivity of the lens groups sequentially increases in order from the image side to the object side, that is, the sensitivity of the standard lens group 300 is higher than that of the image side lens group 30, and the sensitivity of the object side lens group 10 is higher than that of the standard lens group 300.

Therefore, the specific steps for calibrating the object-side lens group 10, the standard lens group 300, and the image-side lens group 30 are: first, the standard lens group 300 is calibrated with reference to the image side lens group 30; next, the object side lens group 10 is calibrated with reference to the image side lens group 30 and the standard lens group 300.

Specifically, at the stage shown in fig. 1C, the image side lens group 30 may be fixedly mounted to the mounting arm 414 of the main housing 41 to dispose the image side lens group 30 in the housing space 43 of the housing 40, i.e., the positional relationship between the image side lens group 30 and the housing 40 is not adjusted. At the stage shown in fig. 1A, the standard lens group 300 is pre-fixed to the mount ring 522 of the mount 52, and therefore, the standard lens group 300 can be calibrated by adjusting the positional relationship (including the Z direction and the XY direction) between the standard lens group 300 and the mount ring 522 with respect to the image side lens group 30. At the stage shown in fig. 1D, the object-side lens group 10 is pre-attached to the flange 412 of the main housing 41, and after the object-side lens group 10 is aligned with respect to the image-side lens group 30 and the standard lens group 300, the attachment relationship between the object-side lens group 10 and the main housing 41 is fixed. For example, at the stage shown in fig. 1D, the object-side lens group 10 may be pre-attached to the flange 412 of the main housing 41 by glue, and after the object-side lens group 10 is aligned with respect to the image-side lens group 30 and the standard lens group 300, the attachment relationship between the object-side lens group 10 and the main housing 41 is fixed by curing the glue.

Referring to fig. 1E and 1F, the standard lens group 300 is removed through the fitting passage 413 of the main housing 41. In the process of removing the standard lens group 300, in order to avoid the main housing 41 scratching the standard lens group 300, the standard lens group 300 is laterally removed. That is, the standard lens group 300 is moved in a direction perpendicular to the optical axis of the optical lens 100 through the fitting passage 413 of the main housing 41 to perform a removing operation on the standard lens group 300.

Referring to fig. 1G and fig. 1H, the focusing lens group 20 is moved into the assembling passage 413 of the main housing 41, and the focusing lens group 20 is pre-fixed on the carrying ring 522 of the carrying portion 52. In the process of moving into the focusing lens group 20, in order to prevent the main housing 41 from scratching the focusing lens group 20, the focusing lens group 20 is moved laterally in. That is, the focus lens group 20 is moved in a direction perpendicular to the optical axis of the optical lens 100 through the fitting passage 413 of the main housing 41 to perform a moving-in operation on the focus lens group 20.

Preferably, the focusing lens group 20 comprises a focusing lens 21, wherein the thickness dimension of the focusing lens 21 is smaller than the height dimension of the assembling channel 413 of the main housing 41, the width dimension of the focusing lens 21 is smaller than the width dimension of the assembling channel 413 of the main housing 41, so as to allow the focusing lens 21 to be smoothly moved into the housing space 43 of the housing 40 through the assembling channel 413 of the main housing 41, and the bearing ring 522 pre-fixed on the bearing part 52.

Preferably, the focusing lens 21 has at least one holding portion 211 to facilitate being held by a clamp when assembling the focusing lens 21.

In a specific example of the optical lens 100 of the present invention, the focus lens group 20 is pre-fixed to the carrying ring 522 of the carrying part 52 by glue.

After the focus lens group 20 is pre-fixed to the carrier ring 522 of the carrier 52, the focus lens group 20 is aligned with reference to the object-side lens group 10 and the image-side lens group 30, for example, by adjusting the positional relationship (including the X direction and the XY direction) between the focus lens group 20 and the carrier ring 522, and at this time, the glue for pre-fixing the focus lens group 20 and the carrier ring 522 can compensate for the gap between the focus lens group 20 and the carrier ring 522 to adjust the relative position between the focus lens group 20 and the carrier ring 522. After the focusing lens group 20 is calibrated, the focusing lens group 20 and the carrying ring 522 can be fixed by means of curing glue.

Referring to fig. 1I, the cover 60 is attached, wherein a bottom side of the cover 60 extends to and is attached to the main casing 41, an inner side of the cover 60 extends to and is attached to the object-side barrel 11 of the object-side lens group 10, so as to allow the cover 60 to close the mounting passage 413 of the main casing 41, thereby preventing contaminants such as dust from entering the casing space 43 of the casing 40 through the mounting passage 413 of the main casing 41 to contaminate the focus lens group 20 and the image-side lens group 30,

in the assembling process of the optical lens 100 of the present invention, the standard lens group 300 is introduced to calibrate the optical lens 100 under a high threshold performance, so as to accurately calibrate the decentering and compensate for the assembling errors of the object-side lens group 10, the focus lens group 20 and the image-side lens group 30.

Fig. 3 and 4 illustrate a camera module 1000 according to a preferred embodiment of the present invention, wherein the camera module 1000 includes a photosensitive element 200 and the optical lens 100 disposed on the photosensitive element 200.

The photosensitive assembly 200 includes a circuit board 201, a photosensitive chip 202, a lens holder 203, and an optical filter 204, wherein the photosensitive chip 202 is attached to the circuit board 201, wherein the lens holder 203 is disposed on the circuit board 201 in a manner that the lens holder 203 at least surrounds a photosensitive area of the photosensitive chip 202, wherein the optical filter 204 is attached to a top side of the lens holder 203 in a manner that the optical filter 204 is maintained in a photosensitive path of the photosensitive chip 202, and wherein the optical lens 100 is directly disposed on the lens holder 203. The incident light can be received by the photosensitive chip 202 after sequentially passing through the optical lens 100 and the optical filter 204 of the photosensitive assembly 200, so that the photosensitive chip 202 can perform photoelectric conversion and image formation subsequently.

Preferably, the mirror base 203 is integrally formed with the circuit board 201, such that: on one hand, a glue layer is not required to be arranged between the mirror base 203 and the circuit board 201, so that the height of the camera module 1000 can be reduced, and on the other hand, the mirror base 203 can reinforce the strength of the circuit board 201, so that the flatness of the circuit board 201 is ensured. Preferably, the lens holder 203 may further embed a portion of a non-photosensitive region of the photosensitive chip 202, such that the lens holder 203 is integrally coupled to the circuit board 201 and the photosensitive chip 202.

In addition, the photosensitive assembly 200 further includes at least one electronic component 205, wherein the electronic component 205 is attached to the circuit board 201, and the electronic component 105 can be embedded in the lens holder 203.

Fig. 5 shows an electronic device according to a preferred embodiment of the present invention, wherein the electronic device includes an electronic device body 2000 and the camera module 1000 disposed on the electronic device body 2000. Preferably, the camera module 1000 is disposed at a front side of the electronic device body 2000 to form a front camera module.

The optical lens 100 of the image capturing module 1000 has a built-in focusing function, that is, the image capturing module 1000 realizes focusing by driving the focusing lens group 20, so that in the process of focusing the image capturing module 1000, the positions of the object-side lens group 10 and the image-side lens group 30 relative to the photosensitive assembly 200 are not changed, and thus the total optical length of the optical lens 100 is not affected, and therefore, the electronic device body 2000 does not need to reserve a space for the optical lens 100 of the image capturing module 1000 to move, which is beneficial to the light and thin of the electronic device.

Moreover, the size of the object-side lens group 10 of the optical lens 100 of the image capturing module 1000 is smaller, and the object-side lens group 10 protrudes from the housing 40, so that the image capturing module 1000 adopts a "small head" design, and thus when the image capturing module 1000 is used as a front-mounted image capturing module of the electronic device, on one hand, the object-side lens group 10 can be closer to an aperture position of a screen of the electronic device, which is beneficial for the image capturing module 1000 to obtain a larger field angle and a larger light transmission amount, so as to improve the imaging quality of the image capturing module 1000, and on the other hand, the aperture size of the screen is not increased, and the requirement of aperture miniaturization is met.

Fig. 6 to 7B show the camera module 1000 according to another preferred embodiment of the present invention, different from the camera module 1000 shown in fig. 3 and 4, in the specific example of the camera module 1000 shown in fig. 6 to 7B, the focusing lens group 20 includes a focusing lens barrel 22 and at least one focusing lens 21 disposed on the focusing lens barrel 22.

Further, an annular groove 111 is disposed at a bottom side of the object-side barrel 11 of the object-side lens group 10, so that when the cover 60 is attached, glue for bonding the inner side of the cover 60 and the object-side lens group 10 can enter the annular groove 111 of the object-side barrel 11 after overflowing, and in this way, on one hand, the overflowing glue can be prevented from contaminating the object-side lens group 10, the focusing lens group 20, and the image-side lens group 30 in the housing space 43 of the housing 40, and on the other hand, the overflowing glue can be prevented from forming a protrusion on an inner wall of the housing 40 or an inner wall of the cover 60 to cause stray light.

Preferably, a protrusion 221 of the focus lens barrel 22 of the focus lens group 20 corresponds to the annular groove 111 of the object side barrel 11, and when the focus lens group 20 is driven, the protrusion 221 of the focus lens barrel 22 can enter the annular groove 111 of the object side barrel 11 to allow the object side lens group 10 to move away from the image side lens group 20, in this way, the focus lens group 20 can have a larger stroke range.

It should be noted that the annular groove 111 is formed at the bottom side of the object-side barrel 11 by disposing two convex rings 112, and the two convex rings 112 of the object-side barrel 11 and the protrusion 221 of the focusing barrel 22 cooperate with each other to reduce stray light, so as to improve the imaging effect of the camera module 1000.

According to an aspect of the present invention, the present invention provides an assembling method of the optical lens 100, wherein the assembling method includes the following steps:

(a) Disposing the object side lens group 10 in the housing space 43 of the housing 40;
