Description

Technical Field

[0001] This invention relates to optical imaging devices, and more particularly to an optical lens, its assembly method, and a camera module. Background Technology

[0002] In recent years, the market has placed increasingly higher demands on the imaging quality of camera modules in portable electronic devices (such as smartphones). One specific manifestation of this is the expectation that front-facing camera modules in portable electronic devices will have focusing capabilities for better image quality. However, based on current technology, focusing capability in a camera module requires the inclusion of a driver (e.g., a voice coil motor). This means the optical lens of the camera module is mounted on the driver, which drives the lens to move along the optical axis of the camera module to achieve focusing. Adding a driver to the camera module inevitably results in a larger size, increasing both the radial dimension (the dimension perpendicular to the optical axis) and the axial dimension (the thickness direction of the portable electronic device along the optical axis). Clearly, using a driver-equipped front-facing camera module in portable electronic devices contradicts the trend towards thinner and lighter designs. Therefore, front-facing camera modules in portable electronic devices are often fixed-focus modules. However, fixed-focus modules struggle to adjust focus during shooting, leading to significant deficiencies in image quality. How to enable the front-facing camera module configured in portable electronic devices to have focusing capabilities is a research topic that the inventors of this invention have been dedicated to studying. Summary of the Invention

[0003] One object of the present invention is to provide an optical lens, an assembly method thereof, and a camera module, wherein the optical lens has a built-in focusing function, so that the camera module does not need to change the position and size of the entire optical lens when focusing. In other words, the camera module does not affect the overall optical length of the optical lens during focusing, which is beneficial for reducing the height of the camera module and achieving miniaturization.

[0004] One object of the present invention is to provide an optical lens and its assembly method, as well as a camera module, wherein the optical lens provides a housing, a focusing lens group, and a driving mechanism, the driving mechanism driving the focusing lens group to move along the optical axis of the camera module within the housing space of the housing to achieve focusing of the camera module. Thus, on the one hand, the optical lens is allowed to have a built-in focusing function, and on the other hand, it helps to simplify the assembly steps of the camera module and improve the assembly accuracy of the camera module.

[0005] One object of the present invention is to provide an optical lens, an assembly method thereof, and a camera module, wherein an upper lens group of the optical lens protrudes from the housing and the upper lens group is small in size to allow the optical lens to adopt a "small head" design. Thus, when the camera module is used as a front-facing camera module of an electronic device, the upper lens group of the optical lens can be closer to the opening position of the screen of the electronic device, thereby enabling the camera module to obtain a larger field of view and light transmission, thereby improving the imaging quality of the camera module.

[0006] One object of the present invention is to provide an optical lens and an assembly method thereof, as well as a camera module, wherein the coil of the drive mechanism is recessed to reduce the height of the camera module, thereby making the camera module suitable for electronic devices that pursue thinness and lightness.

The term "a" should not be construed as a limitation on the quantity.

[0055] Refer to the accompanying drawings of the specification of this invention. Figures 1 to 6F A camera module according to a preferred embodiment of the present invention will be disclosed and described in the following description, wherein the camera module includes a photosensitive component 100 and an optical lens 200 disposed on the photosensitive component 100.

[0056] Specifically, see the attached document. Figures 1 to 3B The photosensitive assembly 100 includes a circuit board 101, a photosensitive chip 102, a lens mount 103, and a filter 104. The photosensitive chip 102 is mounted on the circuit board 101. The lens mount 103 is disposed on the circuit board 101 such that it at least surrounds the photosensitive area of ​​the photosensitive chip 102. The filter 104 is mounted on the top side of the lens mount 103 such that it is held in the photosensitive path of the photosensitive chip 102. The optical lens 200 is directly disposed on the lens mount 103. Incident light, after passing sequentially through the optical lens 200 and the filter 104, can be received by the photosensitive chip 102, so that the photosensitive chip 102 can subsequently perform photoelectric conversion to form an image.

[0057] Preferably, the lens mount 103 is integrally formed on the circuit board 101. This eliminates the need for an adhesive layer between the lens mount 103 and the circuit board 101, reducing the height of the camera module. Furthermore, the lens mount 103 reinforces the circuit board 101, ensuring its flatness. Preferably, the lens mount 103 may further embed a portion of the non-photosensitive area of ​​the photosensitive chip 102, thus integrally combining the lens mount 103 with both the circuit board 101 and the photosensitive chip 102.

[0058] In addition, the photosensitive component 100 further includes at least one electronic component 105, wherein the electronic component 105 is mounted on the circuit board 101, and the lens mount 103 may embed the electronic component 105.

[0059] Continue to refer to the appendix Figures 1 to 6F The optical lens 200 includes an upper lens group 10, a focusing lens group 20, and a lower lens group 30. The upper lens group 10, the focusing lens group 20, and the lower lens group 30 are arranged along the optical axis of the camera module to allow incident light to be received by the photosensitive chip 102 after passing sequentially through the upper lens group 10, the focusing lens group 20, and the lower lens group 30 of the optical lens 200, and through the filter 104 of the photosensitive assembly 100. The focusing lens group 20 is allowed to move along the optical axis of the camera module to achieve focusing of the camera module.

[0060] Further, the optical lens 200 includes a housing 40, wherein the housing 40 has a housing space 41 and a top opening 42 and a bottom opening 43 respectively communicating with the housing space 41. The focusing lens group 20 is movably arranged in the housing space 41 of the housing 40, and the focusing lens group 20 corresponds to the top opening 42 of the housing 40. The lower lens group 30 is fixedly arranged in the housing space 41 of the housing 40, such that when the focusing lens group 20 is driven to move along the optical axis of the camera module, the relative positions of the focusing lens group 20 and the lower lens group 30 are adjusted. The upper lens group 10 is attached to the housing 40 in such a way that the upper lens group 10 corresponds to the top opening 42 of the housing 40, so as to allow the upper lens group 10 to protrude from the housing 40, so that the relative position of the focusing lens group 20 and the upper lens group 10 is adjusted when the focusing lens group 20 is driven to move along the optical axis of the camera module.

[0061] It is understood that by attaching the upper lens group 10 to the housing 40 and fixing the lower lens group 30 to the housing space 41 of the housing 40, the relative positions of the upper lens group 10 and the lower lens group 30 remain unchanged. Furthermore, by attaching the upper lens group 10 to the housing 40, refer to the attached... Figures 1 to 6FThe upper lens group 10 is relatively small in size, which allows the optical lens 200 to adopt a "small head" design. Thus, when the camera module is used as the front camera module of an electronic device, the upper lens group 10 of the optical lens 200 can be closer to the opening position of the screen of the electronic device, which is conducive to the camera module obtaining a larger field of view and light transmission, thereby improving the imaging quality of the camera module.

[0062] Specifically, see the attached document. Figures 1 to 6F The upper lens group 10 includes a first lens barrel 11 and at least one first lens element 12 mounted on the first lens barrel 11, wherein the first lens barrel 11 is attached to the housing 40 to mount the upper lens group 10 to the housing 40. The focusing lens group 20 includes at least one second lens element 21. The lower lens group 30 includes a third lens barrel 31 and at least one third lens element 33 mounted on the third lens barrel 31, wherein the third lens barrel 31 is mounted to the housing 40 to fix the lower lens group 30 in the housing space 41 of the housing 40.

[0063] In a specific example of the camera module of the present invention, the upper lens group 10 includes a first lens barrel 11 and two first lenses 12. The two first lenses 12 are arranged sequentially along the height direction of the first lens barrel 11. Each of the two first lenses 12 has an optically effective area and an optically ineffective area surrounding the optically effective area. The optically effective area of ​​the first lens 12 is used to collect light and change the direction of light. Adhesive is applied to the side of the optically ineffective area of ​​the first lens 12 to bond the first lens 12 to the inner wall of the first lens barrel 11, thereby protecting and supporting the first lens 12 by the first lens barrel 11. Preferably, the surface of the first lens 12 is arc-shaped to converge light and increase the amount of light entering. The first lens 12 may be, but is not limited to, a resin lens.

[0064] The second lens 21 may be provided with at least one clamping part 221 so that the second lens 21 can be clamped by a clamp through the clamping part 221 when assembling the focusing lens group 20.

[0065] Optionally, in other variations of the camera module of the present invention, the focusing lens group 20 includes a second lens barrel and a second lens 21 disposed in the second lens barrel. The second lens 21 has an optically effective area and an optically ineffective area surrounding the optically effective area. The optically effective area of ​​the second lens 21 is used to collect light and change the direction of the light. Adhesive is applied to the side of the optically ineffective area of ​​the second lens 21 to bond the second lens 21 to the inner wall of the second lens barrel, thereby protecting and supporting the second lens 21 by the second lens barrel. The second lens 21 may be, but is not limited to, a resin lens. Preferably, the outer edge of the second lens barrel has at least one clamping portion 211. On the one hand, this facilitates clamping the focusing lens group 20 by a clamp through the clamping portion 211 of the second lens barrel during assembly. On the other hand, adhesive can be applied to the lower surface of the clamping portion 211 to bond the second lens barrel and the components supporting the second lens barrel 21, thereby increasing the stability and reliability of the camera module.

[0066] The lower lens group 30 includes a third lens barrel 31 and a plurality of third lens elements 32. These third lens elements 32 are arranged sequentially along the height direction of the third lens barrel 31. Correspondingly, each of the third lens elements 32 has an optically effective area and an optically ineffective area surrounding the optically effective area. The optically effective area of ​​the third lens element 32 is used to collect light and change the direction of light. Adhesive is applied to the side of the optically ineffective area of ​​the third lens element 32 to bond it to the inner wall of the third lens barrel 31, thereby protecting and supporting the third lens element 32 by the third lens barrel 31. Preferably, the outer diameter of the lower lens group 30 is larger than the outer diameter of the focusing lens group 20. (Continue referring to the appendix...) Figures 1 to 6F The housing 40 includes a shell body 44, a surrounding body 45, and at least one mounting arm 46. The surrounding body 45 extends integrally downward from the periphery of the shell body 44 to form the housing space 41 of the housing 40 between the surrounding body 45 and the shell body 44, and defines the bottom opening 43 of the housing 40 by the surrounding body 45, wherein the top opening 42 of the housing 40 is formed in the shell body 44, and wherein the first lens barrel 11 of the upper lens group 10 is attached to the shell body 44 of the housing 40. The mounting arm 46 extends integrally downward from the inner wall of the shell body 44 such that the mounting arm 46 is located in the housing space 41 of the housing 40, wherein the third lens barrel 31 of the lower lens group 30 is mounted on the mounting arm 46 of the housing 40 to fix the lower lens group 30 in the housing space 41 of the housing 40.

[0067] Preferably, the housing 40 includes two mounting arms 46 that extend integrally downward from the inner wall of the housing body 44 in a spaced-apart and symmetrical manner to form two movable channels 47 between the two mounting arms 46. It is understood that the movable channels 47 of the housing 40 communicate the spaces on opposite sides of the mounting arms 46.

[0068] It is worth mentioning that the mounting method of the third lens barrel 31 of the lower lens group 30 and the mounting arm 46 of the housing 40 is not limited in the optical lens 200 of the present invention. For example, the third lens barrel 31 of the lower lens group 30 and the mounting arm 46 of the housing 40 can be mounted by means of, but not limited to, adhesive bonding.

[0069] Preferably, refer to the appendix Figure 5A and Figure 5B The mounting arm 46 of the housing 40 has at least one slot 461, and correspondingly, the third lens barrel 31 of the lower lens group 30 has at least one protrusion 311, wherein the protrusion 311 of the third lens barrel 31 is engaged with the slot 461 of the mounting arm 46. The lower lens group 30 can be reliably mounted on the housing 40 by means of the mutual cooperation between the protrusion 311 of the third lens barrel 31 and the slot 461 of the mounting arm 46, so as to prevent the lower lens group 30 from rotating relative to the housing space 41 of the housing 40.

[0070] Specifically, each of the mounting arms 46 of the housing 40 has two slots 461, which are formed on opposite sides of the mounting arm 46. Correspondingly, the third lens barrel 31 of the lower lens group 30 has four protrusions 311, wherein each protrusion 311 of the third lens barrel 31 is respectively engaged in each slot 461 of the mounting arm 46.

[0071] Optionally, the slot 461 is formed in the third lens barrel 31, and the protrusion 311 is formed in the mounting arm 46, wherein the protrusion 311 of the mounting arm 46 is engaged with the slot 461 of the third lens barrel 31. The lower lens group 30 can be reliably mounted on the housing 40 by the mutual cooperation between the protrusion 311 of the mounting arm 46 and the slot 461 of the third lens barrel 31, so as to prevent the lower lens group 30 from rotating relative to the housing space 41 of the housing 40.

[0072] Continue to refer to the appendix Figures 1 to 6FThe optical lens 200 further includes a driving mechanism 50, which includes a fixing part 51, a supporting part 52 and a driving part 53. The driving part 53 is configured to drive the supporting part 52 to move relative to the fixing part 51.

[0073] The fixing part 51 is fixedly or integrally disposed on the surrounding body 45 of the housing 40. In other words, in a preferred embodiment of the camera module of the present invention, the fixing part 51 and the housing 40 are an integral structure, for example, the fixing part 51 and the housing 40 can be integrally formed by injection molding; in another preferred embodiment of the camera module of the present invention, refer to the attached drawing. Figures 2 to 3B The fixing part 51 and the outer shell 40 are separate structures, that is, the fixing part 51 and the outer shell 40 are provided separately, and the fixing part 51 is fixedly disposed on the surrounding body 45 of the outer shell 40.

[0074] It is worth mentioning that the way the fixing part 51 is fixedly disposed on the housing 40 is not limited in the camera module of the present invention. For example, the fixing part 51 can be fixedly disposed on the housing 40 by means of adhesive bonding, or the fixing part 51 and the housing 40 can be fixedly installed by means of a snap-fit ​​structure.

[0075] The support portion 52 has a support outer side 5201 and a support inner side 5202 corresponding to the support outer side 5201. The support outer side 5201 of the support portion 52 extends to a position adjacent to the fixing portion 51, and the support inner side 5202 of the support portion 52 extends to the upper side of the lower lens group 30. The focusing lens group 20 is fixedly disposed on the support inner side 5202 of the support portion 52, thus the support portion 52 is used to hold the focusing lens group 20 above the lower lens group 30. When the driving portion 53 drives the support portion 52 to move relative to the fixing portion 51 at the support outer side 5201, the focusing lens group 20 is allowed to move along the optical axis of the camera module to achieve focusing of the camera module.

[0076] It is worth mentioning that the manner in which the supporting portion 52 holds the focusing lens group 20 above the lower lens group 30 is not limited in the optical lens 200 of the present invention. For example, refer to the attached drawing. Figures 2 to 3BThe optical lens 200 of the present invention may include at least one spring 80, wherein the outer side of the spring 80 extends to and is fixed to the fixing part 51, and the inner side of the spring 80 extends to and is fixed to the bearing outer side 5201 of the bearing part 52. Thus, the spring 80 and the bearing part 52 cooperate to allow the focusing lens group 20 to be suspended and held above the lower lens group 30, thereby keeping the focusing lens group 20 in a relatively stable state when the camera module is not in operation. When the driving part 53 drives the bearing part 52 to move the focusing lens group 20 upward along the optical axis of the camera module, the spring 80 deforms upward synchronously. Correspondingly, when the driving part 53 drives the bearing part 52 to move the focusing lens group 20 downward along the optical axis of the camera module, the spring 80 deforms downward synchronously.

[0077] It is worth mentioning that the number of springs 202 in the optical lens 200 of the present invention is not limited. For example, in this preferred example of the optical lens 200 of the present invention, the optical lens 200 includes one spring 202, the outer side of which extends to and is fixedly connected to the upper side of the fixing part 51, and the inner side of which extends to and is fixedly connected to the upper side of the driven member 521; or, the outer side of which extends to and is fixedly connected to the lower side of the fixing part 51, and the inner side of which extends to and is fixedly connected to the lower side of the driven member 521. Optionally, in other examples of the optical lens 200 of the present invention, the optical lens 200 includes two springs 202, one spring 202 extending outward to and fixedly connected to the upper side of the fixing part 51, and extending inward to and fixedly connected to the upper side of the driven member 521, and the other spring 202 extending outward to and fixedly connected to the lower side of the fixing part 51, and extending inward to and fixedly connected to the lower side of the driven member 521.

[0078] Continue to refer to the appendix Figures 1 to 6F The driving unit 53 further includes at least one magnet 531 and at least one coil 532. The magnet 531 is fixedly disposed on the fixed part 51, and the coil 532 is fixedly disposed on the outer side 5201 of the bearing part 52. The positions of the magnet 531 and the coil 532 correspond to each other. When the coil 532 is powered, the magnetic field generated by the coil 532 interacts with the magnet 531 to drive the bearing part 52 to move relative to the fixed part 51. In this way, the bearing part 52 drives the focusing lens group 20 to move along the optical axis of the camera module to achieve focusing of the camera module.

[0079] It is worth mentioning that the coil 532 of the driving unit 53 can be electrically connected to the circuit board 101 of the photosensitive component 100 to allow power to be supplied to the coil 532 of the driving unit 53 through the circuit board 101, thus facilitating the assembly of the camera module into the electronic device.

[0080] Optionally, in other examples of the camera module of the present invention, the magnet 531 of the driving part 53 is fixedly disposed on the outside of the support part 52, and correspondingly, the coil 532 is fixedly disposed on the fixing part 51, and the positions of the magnet 531 and the coil 532 correspond to each other, wherein when the coil 532 of the driving part 53 is powered, the magnetic field generated by the coil 532 interacts with the magnet 531 to drive the support part 52 to move relative to the fixing part 51.

[0081] Continue to refer to the appendix Figures 1 to 6F The fixing part 51 is annular and located outside the focusing lens group 20. The driving part 53 includes two magnets 531, which are symmetrically arranged on opposite sides of the fixing part 51, thus symmetrically arranged outside the focusing lens group 20. The bearing part 52 has an annular bearing outer side 5201, located outside the focusing lens group 20. The driving part 53 includes a coil 532, which is wound around the bearing outer side 5201 of the bearing part 52, thus annular and located outside the focusing lens group 20. With the above structure, when the coil 532 is powered, the magnetic field generated by the annular coil 532 and the two symmetrically arranged magnets 531 interact to drive the focusing lens group 20 to move along the optical axis of the camera module in a balanced manner through the support part 52, so as to avoid the focusing lens group 20 from tilting when being driven, thereby ensuring the optical performance of the camera module.

[0082] Preferably, the support portion 52 forms an annular winding groove 5203 on the outer support side 5201, wherein the coil 532 is wound around the winding groove 5203 of the support portion 52 to ensure that the coil 532 is fixedly disposed on the outer support side 5201 of the support portion 52.

[0083] It is worth mentioning that the assembly method of the magnet 531 of the driving part 53 and the fixing part 51 is not limited in the optical lens 200 of the present invention. For example, the magnet 531 can be glued to the inner wall of the fixing part 51 so that the magnet 531 is fixedly disposed in the fixing part 51. (See attached...) Figures 1 to 6F In this preferred example of the optical lens 200 shown, the fixing part 51 has at least one mounting groove 511, wherein the magnet 531 is mounted in the mounting groove 511 of the fixing part 51, and the magnet 531 is fixedly disposed in the mounting groove 511 of the fixing part 51.

[0084] Preferably, the fixing part 51 surrounds the lower lens group 30, so that the two magnets 531 are symmetrically arranged on opposite sides of the lower lens group 30. Correspondingly, the height position of the outer support 5201 of the support part 52 is lower than the height position of the inner support 5202. In this way, while ensuring that the focusing lens group 20 is held on the upper side of the lower lens group 30, the support part 52 allows the coil 532 wrapped around the outer support 5201 of the support part 52 to surround the lower lens group 30 and correspond to the magnet 531. In this way, the coil 532 of the drive mechanism 50 can be lowered, which helps to reduce the height of the camera module, thereby making the camera module suitable for electronic devices that pursue thinness and lightness.

[0085] Specifically, see the attached document. Figures 1 to 6F The support portion 52 further includes a driven member 521, a support ring 522, and at least one extension arm 523 extending between the driven member 521 and the support ring 522. The driven member 521 is formed on the outer support side 5201 of the support portion 52 to allow the coil 532 of the drive portion 53 to be wound around the driven member 521. The support ring 522 forms the inner support side 5202 of the support portion 52 to allow the focusing lens group 20 to be fixedly disposed on the support ring 522. The extension arm 523 of the support portion 52 is movably disposed in the movable channel 47 of the housing 40, such that the driven member 521 and the support ring 522 of the support portion 52 can be respectively held on opposite sides of the mounting arm 46 of the housing 40.

[0086] Preferably, the support portion 52 includes two extension arms 523, which extend symmetrically between the driven member 521 and the support ring 522.

[0087] Preferably, the driven member 521, the carrying ring 522, and the two extension arms 523 of the carrying portion 52 can be an integral structure, such that one end of each of the two extension arms 523 extends to and is integrally connected to the driven member 521, and the other end extends to and is integrally connected to the carrying ring 522.

[0088] Preferably, at least a portion of the extension arm 523 of the support portion 52 is inclined, such that the height of the outer support side 5201 of the support portion 52 is lower than the height of the inner support side 5202, causing the coil 532 of the drive portion 53 to sink. In other words, the height of the driven member 521 of the support portion 52 is lower than the height of the support ring 522, such that the support portion 52 is configured to allow the driven member 521 to surround the lower lens group 30 and to keep the support ring 522 on the upper side of the lower lens group 30.

[0089] Specifically, see the attached document. Figures 2 to 3B , Figures 5A to 6F The extension arm 523 of the support portion 52 has a lower horizontal extension portion 5231, an upper horizontal extension portion 5232, and an inclined extension portion 5233. The lower horizontal extension portion 5231 extends inward integrally from the driven member 521, and the upper horizontal extension portion 5232 extends outward integrally from the support ring 522. The opposite ends of the inclined extension portion 5233 extend to and are connected to the lower horizontal extension portion 5231 and the upper horizontal extension portion 5232, respectively. Thus, the height position of the driven member 521 of the support portion 52 is lower than the height position of the support ring 522, causing the coil 532 of the drive portion 53 to sink, which helps to reduce the height of the camera module.

[0090] In an optional example of the optical lens 200 of the present invention, the extension arm 523 of the carrier portion 52 is composed of the lower horizontal extension portion 5231 and the inclined extension portion 5233, wherein the lower horizontal extension portion 5231 extends integrally inward from the driven member 521, and the opposite ends of the inclined extension portion 5233 extend to and are connected to the lower horizontal extension portion 5231 and the carrier ring 522, respectively.

[0091] In another alternative example of the optical lens 200 of the present invention, the extension arm 523 of the support portion 52 is composed of the upper horizontal extension portion 5232 and the inclined extension portion 5233, wherein the upper inclined extension portion 5232 extends outward integrally from the support ring 522, and the opposite ends of the inclined extension portion 5233 extend to and are connected to the upper horizontal extension portion 5232 and the driven member 521, respectively.

[0092] In another alternative example of the optical lens 200 of the present invention, the extension arm 523 of the support portion 52 is inclined as a whole, that is, the opposite ends of the extension arm 523 extend to and are connected to the driven member 521 and the support ring 522 respectively in such an inclined manner as the extension arm 523 is inclined as a whole.

[0093] Furthermore, the drive mechanism 50 further includes a carrier 54, wherein the carrier 54 surrounds the second lens 21 of the focusing lens group 20, and the carrier 54 is mounted on the support ring 522 of the support portion 52, thereby fixing the focusing lens group 20 to the support portion 52 by the carrier 54. The second lens 21 of the focusing lens group 20 can be glued to the carrier 54, that is, the carrier 54 is a component for supporting the focusing lens group 20, wherein the clamping portion 211 of the second lens 21 increases the bonding area between the focusing lens group 20 and the carrier 54 to ensure the reliability of the camera module.

[0094] Continue to refer to the appendix Figures 1 to 6F The housing 40 has at least one clearance space 48, which connects the housing space 41 and the top opening 42. The extension arm 523 of the support portion 52 corresponds to the clearance space 48 of the housing 40, allowing the housing 40 to avoid the extension arm 523 of the support portion 52. This allows the focusing lens group 20 to have a larger range of travel. It is understood that the width of the clearance space 48 of the housing 40 is slightly larger than the width of the extension arm 523 of the support portion 52. This prevents the extension arm 523 of the support portion 52 from contacting the housing 40 when the focusing lens group 20 is driven to move along the optical axis of the camera module, thus ensuring the reliability of the camera module. Preferably, the clearance space 48 of the housing 40 is slightly larger than the size of the focusing lens group 20, so that the focusing lens group 20 is allowed to move into the housing space 41 of the housing 40 through the clearance space 48 of the housing 40.

[0095] Preferably, the housing 40 has two clearance spaces 48, which are symmetrically formed on opposite sides of the top opening 42, wherein each of the extension arms 523 of the support portion 52 corresponds to each of the clearance spaces 48 of the housing 40.

[0096] Furthermore, the optical lens 200 includes a cover 60 having a central perforation 61. The cover 60 is attached to the housing surface 44 of the housing 40 such that the upper lens group 10 is held in the central perforation 61 of the cover 60, and the cover 60 closes the clearance space 48 of the housing 40. In this way, dust and other contaminants can be prevented from entering the interior of the optical lens 200 through the clearance space 48 of the housing 40 of the optical lens 200, thus ensuring the reliability of the optical lens 200.

[0097] Furthermore, the optical lens 200 includes a base 70 having a light channel 71. The base 70 is mounted to the surround 45 of the housing 40 such that the lower lens group 30 corresponds to the light channel 71 of the base 70. Thus, the upper lens group 10, the housing 40, and the lens mount 70 form the general appearance of the optical lens 200. The base 70 of the optical lens 200 is mounted to the lens mount 103 of the photosensitive assembly 100, thereby arranging the optical lens 200 in the light-sensing path of the photosensitive assembly 100 to form the camera module.

[0098] Appendix Figure 7 A modified example of the camera module of the present invention is shown, with reference to the appendix. Figures 1 to 6F The difference between the camera module shown and the one in question is that, in the attached... Figure 7 In this specific example of the camera module shown, the lower lens group 30 is directly and fixedly mounted on the base 70, such that the base 70 and the housing 40 cooperate to ensure the relative positional relationship between the lower lens group 30 and the upper lens group 10. For example, the periphery of the third lens barrel 31 of the lower lens group 30 can be glued to the base 70 to allow the lower lens group 30 to be directly and fixedly mounted on the base 70.

[0099] Appendix Figure 6F The assembly process of the optical lens 200 of the present invention is shown, which includes the following stages:

[0100] A standard lens group 300 is pre-fixed to the support ring 522 of the support part 52;

[0101] The support portion 52 is movably disposed in the housing space 41 of the housing 40 such that the standard lens group 300 corresponds to the clearance space 48 of the housing 40. At this time, the bottom surface of the standard lens group 300 is higher than the surface of the shell body 44 of the housing 40, so as to allow the standard lens group 300 to be removed laterally.

[0102] The lower lens group 30 is fixedly disposed in the housing space 41 of the housing 40 and the upper lens group 10 is pre-fixed to the housing 40, and the lower lens group 30, the standard lens group 300 and the upper lens group 10 are substantially coaxial;

[0103] Calibrate the lower lens group 30, the standard lens group 300, and the upper lens group 10;

[0104] The standard lens group 300 is removed and the focusing lens group 20 is moved in through the clearance space 48 of the housing 40 to obtain the optical lens.

[0105] During the assembly of the optical lens 200, the overall threshold of the optical lens 200 can be improved by introducing the standard lens group 300, thereby adjusting the optical lens 200 under high threshold performance.

[0106] Preferably, during the assembly of the optical lens 200, after the focusing lens group 20 replaces the standard lens group 300, the upper lens group 10, the focusing lens group 20, and the lower lens group 30 are recalibrated. This helps to ensure the optical performance of the optical lens 200 and the imaging quality of the camera module.

[0107] Preferably, during the assembly of the optical lens 200, the standard lens group 300 is removed by moving it along the direction perpendicular to the optical axis of the optical lens 200 through the clearance space 48 of the housing 40. Correspondingly, the focusing lens group 20 is moved in by moving it along the direction perpendicular to the optical axis of the optical lens 200 through the clearance space 48 of the housing 40.

[0108] According to another aspect of the present invention, the present invention further provides a method for assembling the optical lens 200, wherein the assembly method includes the following steps:

[0109] (a) The lower lens group 30 is fixedly disposed in the housing space 41 of the housing 40;

[0110] (b) Mounting the upper lens group 10 to the housing 40 such that it protrudes from the housing 40; and

[0111] (c) The focusing lens group 20 is drivably disposed in the housing space 41 of the housing 40 such that the upper lens group 10, the focusing lens group 20 and the lower lens group 30 are coaxial, so as to obtain the optical lens.

[0112] Preferably, prior to step (b), the assembly method further includes the step of:

[0113] (d) Pre-fix the upper lens group 10 to the housing 40;

[0114] (e) The standard lens group 300 is kept between the upper lens group 10 and the lower lens group 30 in such a way that the upper lens group 10, the standard lens group 300 and the lower lens group 30 are coaxial;

[0115] (f) Calibrate the standard lens group 300 using the lower lens group 30 as a reference; and

[0116] (g) Using the lower lens group 30 and the standard lens group 300 as references, calibrate the upper lens group 10.

[0117] In the assembly method of the present invention, the overall threshold of the optical lens 200 can be improved by introducing the standard lens group 300, thereby adjusting the optical lens 200 under high threshold performance.

[0118] It is worth mentioning that the relationship between the upper lens group 10, the focusing lens group 20, and the lower lens group 30 of the optical lens 200 is as follows: (1) the gap in the Z direction mainly affects the field curvature of the optical lens 200; (2) the position in the XY direction mainly affects the peak value of the optical lens 200; (3) the tilt between the upper lens group 10, the focusing lens group 20, and the lower lens group 30 mainly affects the tilt and astigmatism of the optical lens 200. Since the focusing lens group 20 is replaced by the standard lens group 300 in the assembly method, the relationship between the upper lens group 10, the standard lens group 300, and the lower lens group 30 also satisfies the above content.

[0119] Therefore, when designing the optical lens 200, it is necessary to consider the overall optical performance sensitivity of the optical lens 200 in a balanced way. That is, it is important to avoid making any specific lens or lens group overly sensitive to the relationship between the upper lens group 10, the focusing lens group 20, and the lower lens group 30, so as to prevent the overall optical performance of the optical lens 200 from deteriorating due to the high sensitivity of that lens or lens group 10. However, due to the different functions and optical powers of the lenses, there will inevitably be lens groups with increasing sensitivity. Generally, the sensitivity of the lens group increases sequentially from the image side to the object side. That is, the sensitivity of the focusing lens group 20 is higher than that of the lower lens group 30, and the sensitivity of the upper lens group 10 is higher than that of the focusing lens group 20 (or, the sensitivity of the standard lens group 300 is higher than that of the lower lens group 30, and the sensitivity of the upper lens group 10 is higher than that of the standard lens group 300). Therefore, in the assembly method of the present invention, after calibrating the gaps in the Z direction of the upper lens group 10, the standard lens group 300, and the lower lens group 30, it is necessary to calibrate the positions in the XY directions of the upper lens group 10, the standard lens group 300, and the lower lens group 30 in the overall optical lens 200 in order of increasing sensitivity, so as to ensure the overall optical performance of the optical lens 200.

[0120] Furthermore, in the above method, after removing the standard lens group 300, firstly, through the clearance space 48 of the housing 40, the focusing lens group 20 is allowed to move into the housing space 41 of the housing 40 along the direction perpendicular to the optical axis of the optical lens 200. Secondly, with the lower lens group 30 and the upper lens group 10 as references, the focusing lens group 20 is calibrated to set the focusing lens group 20 in the housing space 41 of the housing 40.

[0121] Preferably, in step (e), the standard lens group 300 is carried by the support portion 52 between the upper lens group 10 and the lower lens group 30, and after the standard lens group 300 is removed, the focusing lens group 20 is moved to the support portion 52, and the support portion 52 carries the focusing lens group 20 in the housing space 41 of the housing 40. More preferably, the gap between the upper lens group 10 and the housing 40 is smaller than the gap between the focusing lens group 20 and the support portion 52, so that when calibrating the focusing lens group 20 with the lower lens group 30 and the upper lens group 10 as a reference, the focusing lens group 20 can be provided with a larger compensation range, so as to compensate for errors and ensure the imaging quality of the camera module with the optical lens 200.

[0122] According to another aspect of the present invention, the present invention further provides a method for assembling an optical lens, wherein the assembly method includes the following steps:

[0123] (A) The standard lens group 300 is pre-fixed to the support ring 522 of the support part 52;

[0124] (B) The support portion 52 is movably disposed in the housing space 41 of the housing 40 such that the standard lens group 300 corresponds to the clearance space 48 of the housing 40;

[0125] (C) The lower lens group 30 is fixedly disposed in the housing space 41 of the housing 40 and the upper lens group 10 is pre-fixed in the housing 40, and the lower lens group 30, the standard lens group 300 and the upper lens group 10 are substantially coaxial.

[0126] (D) Calibrate the lower lens group 30, the standard lens group 300, and the upper lens group 10; and

[0127] (E) The standard lens group 300 is removed and the focusing lens group 20 is moved in through the clearance space 48 of the housing 40 to obtain the optical lens.

[0128] Preferably, the assembly method further includes the step of: (F) allowing the cover 60 to close the clearance space 48 of the housing 40 to prevent dust and other contaminants from entering the interior of the optical lens 200 through the clearance space 48 of the housing 40 of the optical lens 200, thereby ensuring the reliability of the optical lens 200.

The objectives of the present invention have been fully and effectively achieved.
