Description

Technical Field

[0001] The present invention relates to the field of camera modules, and in particular to a periscope camera module, an array camera module, a manufacturing method thereof, and electronic equipment. Background Art

[0002] With technological advancements and economic development, people are demanding higher and higher camera capabilities in portable electronic devices, such as tablets, camcorders, and smartphones. Simultaneously, the demand for camera modules for these devices is increasing, leading to increasingly fierce competition. In particular, the design requirements for array camera modules are becoming increasingly demanding. Array camera modules are not only required to achieve background blur and clear nighttime photography, but also to achieve optical zoom without increasing module height. This has led to the development of periscope array camera modules.

[0003] A periscope array camera module is typically composed of a periscope camera module and an upright camera module. The periscope camera module uses a prism at the front end of the upright module to reflect vertical light incident on the end of the camera module, thereby converting vertical light into horizontal light incident on the camera module. This allows the camera module to be placed horizontally, reducing its height.

[0004] On the other hand, higher requirements are placed on the imaging quality of each camera module in a periscope array camera module. For periscope camera modules, the optical properties of their lenses determine their imaging quality. Ensuring optical axis alignment—that is, ensuring the central axes of each lens are aligned and aligned with the central axis of the photosensitive chip—is fundamental to ensuring good imaging quality. Traditional lenses typically assemble multiple lenses sequentially into a lens barrel. During the assembly process, there is inevitably some error between each lens and the barrel. Ultimately, the assembly between the lenses and the barrel creates a cumulative error, which is the assembly error of the individual lenses. It's easy to understand that the greater the number of lenses, the greater the cumulative error, the lower the overall lens quality, and the lower the yield rate during lens production. Furthermore, with traditional lenses, multiple lenses are assembled into a single barrel, and the relative positions of the lenses are essentially fixed and cannot be adjusted. Once the lenses are assembled into the barrel, the lens quality is set, which also places high demands on the machining precision of the barrel and lenses.

[0005] On the other hand, traditional periscope camera modules consist of components such as a prism, lens, motor, and photosensitive element. The lens is assembled first, followed by the lens, photosensitive element, and prism. This assembly method uses mechanical positioning, which cannot guarantee the angular relationship between the prism and lens end faces. This angular relationship depends on the machining accuracy of the prism and lens. Furthermore, assembly errors are inevitable in the assembly of the lens, motor, photosensitive element, and prism. This mechanical positioning method leads to increasing cumulative tolerances, impacting the imaging quality of the periscope camera module. Furthermore, in traditional lens design (where the complete lens is assembled first, followed by the motor and prism), the lower assembly precision requires more margin for error in the motor. For example, within the focusing range, the lens only moves 600μm. However, due to the lower assembly precision, a larger margin for lens movement and a larger space for lens installation must be designed. Consequently, the AF motor travel is designed to be 800μm, resulting in a larger motor structure. Consequently, the periscope camera module is larger.

[0006] In addition, the lens and motor are installed on the motor circuit board. The motor circuit board has a greater impact on the optical performance of the periscope camera module. The warping of the motor circuit board will affect the installation accuracy of the optical lens, and cause deviations in the calibration process of the lens and photosensitive components, resulting in poor optical performance of the module.

[0096] like Figures 1 to 2 As shown in FIG. 1 , a periscope camera module according to a first preferred embodiment of the present invention is illustrated, wherein the periscope camera module 1 includes a light deflection device 10 and a module assembly 20. The light deflection device 10 is maintained in the light-sensing path of the module assembly 20 so as to reflect the light vertically incident on the periscope camera module 1, thereby converting the vertical light into horizontal light incident on the light-sensing assembly 21 of the module assembly 20.

[0097] The light deflection device 10 includes a light deflection unit 11 and a base 12. The light deflection unit 11 is installed on the base 12. The light deflection unit 11 is used to change the direction of light. In particular, in this embodiment of the present invention, the light deflection unit 11 enables the light to achieve a 90-degree direction change. The light deflection unit 11 includes two right-angled surfaces and an inclined surface, and the two right-angled surfaces form an angle of 45 degrees with the inclined surface, and one of the right-angled surfaces is perpendicular to the optical axis of the module assembly 20. For example, but not limited to, the light deflection unit 11 can be implemented as a plane mirror or a prism. In particular, in this embodiment of the present invention, the light deflection unit 11 is implemented as a prism, and in particular, the prism is a total reflection prism. That is, the prism includes the two right-angled surfaces and the inclined surface, and the angle between the inclined surface and the two right-angled surfaces is 45 degrees.

[0098] Furthermore, the light deflection device 10 includes a rotating mechanism 13 for rotating the light deflection unit 11. The rotating mechanism 13 is mounted on the base 12 so that the light deflection unit 11 can be rotated by rotating the base 12. The light deflection device 10 includes an electrical connection element 14 for electrically connecting to the module assembly 20. The electrical connection element 14 electrically connects the rotating mechanism 13 and the module assembly 20 so as to obtain driving kinetic energy from the module assembly 20. That is to say, when the module assembly 20 needs to perform optical image stabilization, electrical energy can be obtained from the module assembly 20 to drive the rotating mechanism 13, and the light deflection unit 11 is driven by the rotating mechanism 13. In particular, the rotating mechanism 13 adjusts the steering mechanism in an axial rotation manner to achieve optical image stabilization in different directions. For example, optical image stabilization in two directions can be achieved by axially rotating along the module optical axis 20 or axially rotating along the incident light axis of the light deflection device 10.

[0099] like Figures 1 to 2 As shown, the module assembly 20 includes a photosensitive component 21, an optical lens 22 and a driving component 23, wherein the optical lens 22 is mounted on the driving component 23, the optical lens 22 and the driving component 23 have an integrated structure, and the driving component 23 can be used to drive the optical lens 22 to move relative to the photosensitive component 21. The driving component 23 is mounted on the photosensitive component 21 so that the optical lens 22 is located in the light sensing path of the photosensitive component 21.

[0100] The photosensitive component 21 includes a photosensitive element 211, a circuit board component 212, a filter element 213, and a support 214. The photosensitive element 211 is electrically connected to the circuit board component 212, the support 214 is mounted on the circuit board component 212, and the filter element 213 is mounted on the support 214. The driving component 23 is mounted on the support 214 so that the lens 21 is located in the light sensing path of the photosensitive element 211, and the optical lens 22 can be adjusted by the driving component 22. The driving component 22 is electrically connected to the circuit board component 212 so as to obtain operating power from the circuit board component 212.

[0101] According to this embodiment of the present invention, the photosensitive element 211 is attached to the circuit board component 212 and electrically connected to the circuit board component 212. For example, the photosensitive element 211 can be implemented as a CCD or CMOS photosensitive chip. In particular, in one embodiment, the photosensitive chip 211 is attached to the circuit board component 212 and electrically connected to the circuit board component 212 via gold wire. The filter element 213 can be implemented as an infrared cutoff filter IRCF, a wafer-level infrared cutoff filter, a blue glass filter, etc.

[0102] The light deflection device 10 is mounted at the end of the drive mechanism 13, opposite the optical lens 22. Furthermore, the optical axis of the optical lens 22 forms a 45-degree angle with the inclined surface 112 of the light deflection unit 11. Specifically, when assembling the periscope camera module 1, the angle between the optical axis of the lens 21 and the inclined surface 112 of the light deflection unit 11 can be adjusted dynamically to 45 degrees by adjusting the light deflection assembly 10 and the module assembly 20.

The carrier 231 and the optical lens 22 have an integrated structure. The driving element 232 is mounted on the carrier 231 and can be used to drive and adjust the movement of the optical lens 22 relative to the photosensitive component 21. The carrier 231 and the driving element 232 are electrically connected to the driving circuit board 233, wherein the driving circuit board 233 is located below the driving element 232 and is mounted on the driving housing 234. By way of example, but not limitation, the driving component 23 can be implemented as a voice coil motor or a piezoelectric motor.

[0104] Furthermore, the carrier 231 has a receiving groove 2311 so that the optical lens 22 can be installed in the receiving groove 2311, and the driving element 232 is installed on the carrier 231. The driving element 232 includes at least one coil and at least one magnet (not shown in the figure), wherein at least one of the coils is located above the carrier 231 and is arranged on both sides of the carrier 231, and the magnet is located below the carrier 231 and is installed below the carrier 231 corresponding to the position of at least one coil. Further, the coil is installed on the driving circuit board 233 and is electrically connected to the driving circuit board 233.

[0105] The driving circuit board 233 is installed on the side wall of the driving housing 234, wherein the optical lens 22 and the carrier 231 having an integrated structure are installed on the driving circuit board 233, wherein the optical lens 22 and the carrier can be adjusted relative to the driving circuit board 233 so as to adjust the installation position between the optical lens 22 and the photosensitive component 21.

[0106] When the optical lens 22 and the carrier 231 are mounted on the driving circuit board 233, the optical lens 22 and the carrier 231 can be assembled in an upright position along the longitudinal direction. The optical lens 22 and the driving component 23 can also be assembled in a horizontal position along the transverse direction to reduce the impact of the warping of the driving circuit board on the assembly of the optical lens 22. In a preferred embodiment of the present invention, the optical lens 22 and the carrier 231 are preferably assembled in a horizontal position on the driving circuit board 233 to reduce the impact of the warping of the driving circuit board 233.

[0107] The optical lens 22 and the carrier 231 are assembled horizontally on the driving circuit board 233, the photosensitive component 21 is installed on the driving component 23, and the circuit board element 212 of the photosensitive component 21 is perpendicular to the driving circuit board 233. The module assembly 20 is installed in a "lying flat" manner. The optical lens 22 and the carrier 231 are laid horizontally on the driving circuit board 233 and actively calibrated with the photosensitive component 21 to reduce the impact of the warping of the driving circuit board 233. The module assembly 20 is installed in a "lying flat" manner to reduce the difficulty of installing the prism, motor and photosensitive component.

[0108] In a preferred embodiment of the present invention, the optical lens 22 includes a plurality of sub-lenses, wherein each sub-lens is sequentially assembled in the photosensitive path of the photosensitive component 21, and the installation position of at least one sub-lens relative to the other sub-lenses can be adjusted.

[0109] like Figure 4 As shown, an optical lens according to a first preferred embodiment of the present invention is described, wherein the optical lens 22 includes a first sub-lens 221 and a second sub-lens 222, wherein the second sub-lens 222 is integrally formed in a receiving groove 2311 of the carrier 231, and the first sub-lens 221 is movably assembled to the carrier 231 to form the optical lens 22. The optical lens 22 is assembled in the light-sensing path of the photosensitive component 21 so that when the photosensitive component 21 is powered on, the installation positions of the first sub-lens 221, the second sub-lens 222 of the optical lens 22, and the photosensitive component 21 can be actively calibrated. More specifically, the so-called active calibration refers to adjusting the relative positions of the first sub-lens 221, the second sub-lens 222, and the photosensitive component 21 based on the imaging effect or test effect of the first sub-lens 221 and the second sub-lens 222 on the photosensitive component 21, so as to achieve an excellent imaging effect or test effect on the photosensitive component 21.

[0110] Furthermore, the second sub-lens 222 is integrally formed in the receiving groove 2311 of the carrier 231, wherein the first sub-lens 221 is installed on the side of the carrier 231, wherein the installation position between the first sub-lens 221 and the second sub-lens 222 can be adjusted.

[0111] It is understandable that, in this embodiment of the present invention, taking the optical lens 22 including two sub-lenses as an example, in other variant implementations, the optical lens may also include more than two sub-lenses.

[0112] like Figure 4 As shown, the first sub-lens 221 includes a first lens group 2211 and a first lens barrel 2212, and the second sub-lens 222 includes a second lens group 2221, wherein the first lens group 2211 is installed in the first lens barrel 2212, and the second lens group 2221 is installed in the carrier 231. More specifically, the second lens group 2211 is assembled in the receiving groove 2311 of the carrier 231. The first sub-lens 221 is assembled with the second sub-lens 222 to form the optical lens 22. Of course, the first lens 221 and the second sub-lens 222 can be further assembled later to form the periscope camera module 20.

[0113] The first lens group 2211 of the first sub-lens 221 further includes a first lens 22111 and a second lens 22112. The second lens group 2221 of the second sub-lens 222 further includes a third lens 22211, a fourth lens 22212, and a fifth lens 22213. It should be noted that in this preferred embodiment, the number of lenses included in the first lens group 2211 and the second lens group 2221 does not limit the subject matter of the present invention. The number of lenses can be adjusted according to the requirements of different camera modules for lenses. For example, the number of lenses in the first lens group 2211 can be one, three, four, or other numbers, and the number of lenses in the second lens group 2221 can be one, two, four, or other numbers. In order to facilitate the description of the results of the lens, each lens is specifically marked. The first lens 22111 and the second lens 22112 are installed on the first lens barrel 2212, the third lens 22211, the fourth lens 22212 and the fifth lens 22213 are installed on the carrier 231, and the first sub-lens 221 is installed on the side of the carrier 231, wherein the position of the first sub-lens 221 relative to the carrier 231 is adjustable.

[0114] In the present invention, the first lens 22111 is arranged on the outside of the first lens barrel 2212, and the first lens 22111 has the largest size compared to the second lens 22112 and the third lens 22211, the fourth lens 22212 and the fifth lens 22213 of the second lens group 2221. The optical The sensitivity is the lowest, and the fifth lens 22213 has the highest optical sensitivity. Therefore, when assembling the first lens group 2211 to the first lens barrel 2212 and assembling the second lens group 2221 to the carrier 231, the first lens 22111 has the largest optical cumulative tolerance relative to the photosensitive chip 21, and the fifth lens 22213 has the smallest optical cumulative tolerance relative to the photosensitive chip 21, thereby solving the problem that the traditional most sensitive optical lens has the largest cumulative tolerance and avoiding the tilt of the image plane of the camera module 20.

[0115] In order to lower the height of the driving component 23, and then lower the height of the module assembly 20, and then lower the height of the periscope camera module, usually, the cross-section of the first lens barrel 2212 is circular, and the cross-section of the first lens 22111 is circular. In order to ensure that the height dimension of the driving component 23 does not increase, the radial dimension of the first lens barrel 2212 is smaller than the height dimension of the carrier 231 (the thickness in the up and down directions), so as to ensure that when the first sub-lens 221 of the optical lens 22 is installed on the carrier 231, there is no need to increase the height of the carrier 231.

[0116] It is worth mentioning that the first sub-lens 221 and the second sub-lens 222 of the optical lens 22 are respectively assembled on the carrier 231, and the carrier 231 is assembled horizontally on the driving circuit board 233, the photosensitive component 21 is adjacent to one end of the second sub-lens 222, and the circuit board element 212 of the photosensitive component 21 is perpendicular to the driving circuit board 233, and the module assembly 20 is installed in a "lying" manner. The optical lens 22 and the carrier 231 lie horizontally on the driving circuit board 233 and are actively calibrated with the photosensitive component 21 to reduce the impact of the warping of the driving circuit board 233, and the module assembly 20 is installed in a "lying" manner to reduce the difficulty of installation between the prism, motor and photosensitive component.

[0117] The first sub-lens 221, the second sub-lens 222 and the photosensitive component 21 are actively calibrated, and the positions of the first sub-lens 221 and the second sub-lens 222 are adjusted respectively according to the imaging effect of the photosensitive component 21, so as to achieve high-precision assembly and reduce the assembly space of the entire driving component 23 and the optical lens 22, which is conducive to reducing the size of the driving component 23.

[0118] like Figure 5 As shown, for example, in order to further reduce the height dimension of the first lens barrel 2212, the first lens barrel 2212 has at least one plane, wherein the at least one plane is integrally formed on the end surface of the first lens barrel 2212, in particular, the at least one plane is integrally formed on the outer end surface of the first lens barrel 2212. Preferably, in the present invention, the first lens barrel includes a first plane 22121 and a second plane 22122, wherein the first plane 22121 and the second plane 22122 are symmetrically formed, in particular, the first plane 22121 and the second plane 22122 are parallel to each other, wherein the distance between the first plane 22121 and the second plane 22122 is smaller than the dimension of the first lens barrel 2212 in the direction other than the first plane 22121 and the second plane 22122 (not the height).

[0119] Preferably, the distance between the first plane 22121 and the second plane 22122 is not greater than the height dimension of the carrier 231 to ensure that the first plane 22121 and the second plane 22122 do not protrude relative to the height of the carrier 231 to prevent the height dimension of the driving component 223 from increasing.

[0120] More preferably, the distance between the first plane 22121 and the second plane 22122 is equal to the height dimension of the carrier 231, so as to ensure that when the first lens barrel 2212 is installed on one side end face of the carrier 231, the first plane 22121 and the second plane 22122 of the first lens barrel 2212 are aligned with the first and second end faces of the carrier 231.

[0121] It is worth mentioning that in the first preferred embodiment of the present invention, Figure 5 As shown, the first lens barrel 2212 is preferably made in one piece by one-piece molding or injection molding, so that the first lens barrel 2212 has the first plane 22121 and the second plane 22122 that are parallel to each other after being made. This not only simplifies the manufacturing process of the first lens barrel 2212, but also prevents the first lens barrel 2212 from being damaged due to subsequent modification. Figure 4As shown, the first lens 22111 of the first lens barrel 2212 is circular. Figure 5 As shown, the first lens barrel 2212 has a first edge plane 22121 and a second edge plane 22122. In order to match the structural size of the first lens 22111 with the first lens barrel, as shown in FIG. Figure 6 As shown, the first lens 22111 includes at least one edge plane, and the at least one edge plane is formed at the edge of the first lens 22111. In particular, the at least one edge plane is formed at the outer edge of the first lens 22111. Preferably, the first lens 221111 includes a first edge plane 221111 and a second edge plane 221112, wherein the first edge plane 221111 and the second edge plane 221112 are symmetrically formed, in particular, the first edge plane 221111 and the second edge plane 221112 are parallel to each other, wherein the distance between the first edge plane 221111 and the second edge plane 221112 is smaller than the size of the first lens 221111 in a plane (not height) where the first edge plane 221111 and the second edge plane 221112 are not located.

[0122] Preferably, if Figure 6 As shown, the distance between the first edge plane 221111 and the second edge plane 221112 of the first lens 22111 is not greater than the distance between the first plane 22121 and the second plane 22122 of the first lens barrel 2212 to ensure that the first lens 22111 can be installed in the first lens barrel 2212.

[0123] More preferably, the distance between the first edge plane 221111 and the second edge plane 221112 is equal to the distance between the first plane 22121 and the second plane 22122 of the first lens barrel 2212, and the first lens 22111 is installed in the first lens barrel 2212 to ensure that the first edge plane 221111 and the second edge plane 221112 are aligned with the first plane 22121 and the second plane 22122 of the first lens barrel 2212.

[0124] It is worth mentioning that in the first preferred embodiment of the present invention, the first lens 22111 is preferably made in one piece by one-piece molding or injection molding, so that the first lens 22111 has the first edge plane 221111 and the second edge plane 221112 after being made, which not only simplifies the production process of the first lens 22111, but also prevents the first lens 22111 from being damaged due to subsequent modification.

[0125] Of course, the first lens 22111 can be cut to form the first edge plane 221111 and the second edge plane 221112 to ensure that the first edge plane 221111 and the second edge plane 221112 are aligned with the first plane 22121 and the second plane 22122 of the first lens barrel 2212.

[0126] like Figure 7 As shown, since the first lens 22111 has the largest radial dimension relative to the other lenses, in order to prevent the radial dimension of the first lens barrel 2212 from being too large, the first lens barrel 2212 has at least one opening, wherein the at least one opening is integrally formed on the end surface of the first lens barrel 2212, and in particular, the at least one opening is integrally formed on the outer end surface of the first lens barrel 2212. Preferably, in a preferred embodiment of the present invention, the first lens barrel 2212 has a first opening 22121A and a second opening 22122A, wherein the first opening 22121A and the second opening 22122A are symmetrically formed, and in particular, the first opening 22121A and the second opening 22122A are parallel to each other.

[0127] Preferably, the distance between the first opening 22121A and the second opening 22122A is not greater than the height dimension of the carrier 231 to ensure that the first opening 22121 and the second opening 22122 do not protrude relative to the height of the carrier 231 to prevent the height dimension of the driving component 223 from increasing.

[0128] More preferably, the distance between the first opening 22121A and the second opening 22122A is equal to the height dimension of the carrier 231, so as to ensure that when the first lens barrel 2212 is installed on one side end surface of the carrier 231, the first opening 22121A and the second opening 22122A of the first lens barrel 2212 are aligned with the two end surfaces of the carrier 231.

[0129] When the first lens 22111 is mounted on the first lens barrel 2212, the first lens 22111 is mounted at the location of the first opening 22121A and the second opening 22122A of the first lens barrel 2212. Part of the first lens 22111 at the location of the first opening 22121A and the second opening 22122A is exposed from the first lens barrel 2212, thereby reducing the radial dimension of the first lens barrel 2212 covering the first lens 22111. To prevent light leakage from the exposed portion of the first lens 22111, the exposed portion of the first lens 22111 may be painted black.

[0130] like Figure 8 As shown, the first lens 22111 includes at least one edge plane, wherein the at least one plane is integrally formed on the end surface of the first lens barrel 2212, in particular, the at least one plane is integrally formed on the outer end surface of the first lens barrel 2212. Preferably, the first lens 22111 includes a first edge plane 221111 and a second edge plane 221112, wherein the first edge plane 221111 and the second edge plane 221112 are symmetrically formed, in particular, the first edge plane 221111 and the second edge plane 221112 are parallel to each other, wherein the distance between the first edge plane 221111 and the second edge plane 221112 is smaller than the size of the first lens 221111 in a plane other than the first edge plane 221111 and the second edge plane 221112 (not the height).

[0131] Preferably, if Figure 8 As shown, the distance between the first edge plane 221111 and the second edge plane 221112 of the first lens 22111 is not greater than the distance between the first opening 22121A and the second opening 22122A of the first lens barrel 2212 to ensure that the first lens 22111 can be installed in the first lens barrel 2212.

[0132] More preferably, the distance between the first edge plane 221111 and the second edge plane 221112 is equal to the distance between the first opening 22121A and the second opening 22122A of the first lens barrel 2212, so as to ensure that the first edge plane 221111 and the second edge plane 221112 and the first opening 22121A and the second opening 22122A of the first lens barrel 2212 are aligned during the process of installing the first lens 22111 on the first lens barrel 2212.

[0133] It is worth mentioning that in the first preferred embodiment of the present invention, the first lens 22111 is preferably made in one piece by one-piece molding or injection molding, so that the first lens 22111 has the first edge plane 221111 and the second edge plane 221112 after being made, which not only simplifies the production process of the first lens 22111, but also prevents the first lens 22111 from being damaged due to subsequent modification.

[0134] Of course, the first lens 221111 can be cut to form the first edge plane 221111 and the second edge plane 221112, so as to ensure that the first edge plane 221111 and the second edge plane 221112 are aligned with the first opening 22121A and the second opening 22122A of the first lens barrel 2212. It is worth mentioning that when the first edge plane 221111 and the second edge plane 221112 of the first lens 22111 are correspondingly mounted on the first opening 22121A and the second opening 22122A of the first lens barrel 2212, in order to prevent light leakage from the first edge plane 221111 and the second edge plane 221112 of the first lens 22111, the exposed portion of the first lens 22111 can be selectively painted black.

[0135] like Figure 9 FIG2 is an illustration of the optical lens of a first variant embodiment of the first preferred embodiment of the present invention, wherein the first sub-lens 221 includes a first lens 22111, wherein the first lens 22111 is mounted on the side of the carrier 231, and wherein the mounting position between the first lens 22111 and the second sub-lens 222 is adjustable. More specifically, the second sub-lens 222 and the carrier 231 have an integrated structure, the second sub-lens 222 is integrally formed in the receiving groove 2311 of the carrier 231, and the first lens 22111 of the first sub-lens 221 is mounted on the side of the carrier 231, forming the optical lens 22. The optical lens 22 is mounted in the light-sensing path of the photosensitive component 21. When the photosensitive component 21 is powered on, the mounting positions between the first lens 22111 of the first sub-lens 221, the second sub-lens 222, and the photosensitive component 21 can be actively calibrated.

[0136] Furthermore, the first lens 22111 is mounted on the side of the carrier 231. The first lens 22111 has the largest diameter. Compared to the second lens group 2222 of the second sub-lens 222, the first lens 22111 has the worst optical sensitivity and the largest cumulative tolerance. To reduce the height of the periscope camera module, the diameter of the first lens 22111 can be reduced. In this preferred embodiment of the present invention, the first lens 22111 is circular, but may also have other shapes.

[0137] like Figure 10As shown, it is an explanation of the optical lens of the second variant embodiment of the first preferred embodiment of the present invention, wherein the optical lens 22 further includes a third sub-lens 223, wherein the third sub-lens 223 is installed on the carrier 231, wherein the first sub-lens 221 includes a first lens 22111, the second sub-lens 222 and the carrier 231 have an integrated structure, and the third sub-lens is installed on the carrier 231, in particular, the first lens 22111 of the first sub-lens 221 is installed on the side of the carrier 231, the second sub-lens 222 is integrally formed on the carrier 231, and the third sub-lens 223 is installed on the carrier 231, wherein the installation positions between the first sub-lens 221, the second sub-lens 222, the third sub-lens 223 and the photosensitive component 21 can be adjusted.

[0138] like Figure 11 , is an illustration of the optical lens of the second preferred embodiment of the present invention, wherein the receiving groove 2311 of the carrier 231 has a first receiving groove 23111 and a second receiving groove 23112, wherein the first sub-lens 221 is mounted in the first receiving groove 23111 of the carrier 231, and the second sub-lens 222 is mounted in the second receiving groove 23112 of the carrier 231, so that the second sub-lens 222 and the carrier 231 have an integrated structure, wherein the second sub-lens 222 and the carrier 231 form a first optical component. In other words, the first optical component includes the second sub-lens 222 and the carrier 231, wherein the second sub-lens 222 is assembled with the carrier 231 to have an integrated structure. The first sub-lens 221 is assembled in the first receiving groove 23111 of the carrier 231 of the first optical component. In this preferred embodiment of the present invention, the first receiving groove 23111 and the second receiving groove 23112 are interconnected, wherein the inner diameter of the first receiving groove 23111 is larger than the inner diameter of the second receiving groove 23112 .

[0139] Therefore, the assembly process of the optical lens 22 is to assemble the first sub-lens 221 to the first optical component so that the installation position between the first sub-lens 221 and the first optical component can be adjusted. Thus, the first sub-lens 221, the carrier 231, and the second sub-lens 222 are assembled to form the optical lens 22. The optical lens 22 is then assembled to the photosensitive path of the photosensitive component 21 to form the module assembly 20. When the photosensitive component 21 is powered on, the installation positions of the first sub-lens 221, the second sub-lens 222, and the photosensitive component 21 of the optical lens 22 can be actively calibrated.

[0140] In this preferred embodiment of the present invention, when the optical lens 22 is installed on the photosensitive component 21 to form the module component 20, the installation position between the first sub-lens 221 and the second lens 222 is subjected to lens calibration, and then the installation position between the calibrated optical lens 22 and the photosensitive component 21 is subjected to active calibration (Active Alignment, abbreviated as AA) to obtain a module component 20 with good imaging quality.

[0141] Preferably, when the optical lens 22 is installed on the photosensitive component 21 to form the module component 20, the installation positions of the first sub-lens 221, the second lens 222 and the photosensitive component 21 can be simultaneously AA-ed to obtain a module component 20 with better imaging quality.

[0142] like Figure 11 As shown, the first lens group 2211 is installed in the first lens barrel 2212, and each lens of each lens group 2211 is installed in the first lens barrel 2212, wherein each lens is installed at the position described in the first lens barrel 2212, and the first lens barrel 2212 has the same wall thickness. In other words, the wall thickness of the first lens barrel 2212 will not change with the radial size of each lens, but the shape of the first lens barrel 2212 will change with the radial size of each lens.

[0143] More specifically, the first lens 22111 has the largest radial dimension relative to the other lenses of the first lens group 2211. When the first lens 22111 is installed in the first lens barrel 2212, the radial dimension of the first lens barrel 2212 at the position of the first lens 22111 in the first lens barrel 2212 is larger than the radial dimensions of the first lens barrel 2212 at the positions of the other lenses in the first lens barrel 2212. Therefore, the first lens barrel 2212 has the same wall thickness but different radial dimensions. The wall thickness of the first lens barrel 2212 is no greater than the wall thickness of the carrier 231, which is conducive to reducing the size of the driving component 23 and further facilitating a reduction in the height of the periscope camera module.

[0144] like Figure 12 FIG. 1 is an illustration of the optical lens of a modified embodiment of the second preferred embodiment of the present invention. Figure 11As shown, compared to the second preferred embodiment according to the present invention, the difference between the first lens barrel of the modified embodiment of the second preferred embodiment according to the present invention is that: the first lens barrel 2212 has the same radial dimension, and the first lens group 2211 is installed in the first lens barrel 2212, wherein the radial dimension of the first lens barrel 2212 where the first lens 22111 is located is greater than the radial dimension of the first lens barrel 2212 where the other lenses (first lens 22112) are located, therefore, the wall thickness of the first lens barrel 2212 is different at different positions, more specifically, the wall thickness of the position of the first lens barrel 2212 where the first lens 22111 is located is less than the wall thickness of the first lens barrel 2212 where the other lenses (second lens 22112) are located. It is worth mentioning that in this preferred embodiment of the present invention, the wall thickness of the first lens barrel 2212 is less than the wall thickness of the carrier, which is conducive to reducing the size of the driving component 23, and thus is conducive to reducing the height dimension of the periscope camera module.

[0145] As attached Figure 13 As shown, an optical lens according to a third preferred embodiment of the present invention is illustrated. The optical lens 22 includes a first sub-lens 221 and a second sub-lens 222A. The optical lens 22 is maintained in the photosensitive path of the photosensitive component 21, and the installation position between the optical lens 22 and the photosensitive component 21 can be adjusted. The first sub-lens 221 and the second sub-lens 222A can be pre-assembled by glue, and the first sub-lens 221 is installed on the second sub-lens 222A. The installation position between the first sub-lens 221 and the second sub-lens 222A can be calibrated by the lens. The first sub-lens 221 and the second sub-lens 222A are both maintained in the photosensitive path of the photosensitive chip 21.

[0146] More specifically, if Figure 13 As shown, the first sub-lens 221 is installed in the first receiving groove 23111 of the carrier 231, so that the first sub-lens 221 and the carrier 231 have an integrated structure, and the second sub-lens 222A is installed in the second receiving groove 23112 of the carrier 231. The integrated structure of the first sub-lens 221 and the carrier 231 forms a second optical component. In other words, the second optical component includes the first sub-lens 221 and the carrier 231, wherein the first sub-lens 221 is assembled with the carrier 231 to have an integrated structure. The second sub-lens 222A is assembled in the second receiving groove 23111 of the carrier 231 of the second optical component.

[0147] Therefore, the assembly process of the optical lens 22 is to assemble the second sub-lens 222A to the second optical component so that the mounting position between the second sub-lens 222A and the second optical component can be adjusted. Thus, the second sub-lens 222A and the second optical component are assembled to form the optical lens 22. The optical lens 22 is then assembled into the light-sensing path of the photosensitive component 21 to form the module assembly 20.

[0148] In this preferred embodiment of the present invention, when the optical lens 22 is installed on the photosensitive component 21 to form the module component 20, the installation position between the first sub-lens 221 and the second lens 222A is calibrated, and then the installation position between the calibrated optical lens 22 and the photosensitive component 21 is actively calibrated to obtain a module component 20 with good imaging quality.

[0149] Preferably, when the optical lens 22 is installed on the photosensitive component 21 to form the module component 20, the installation positions of the first sub-lens 221, the second lens 222A and the photosensitive component 21 can be actively calibrated at the same time to obtain a module component 20 with better imaging quality.

[0150] It is worth mentioning that, in the present invention, both of the above-mentioned two adjustment methods for the module assembly 20 can achieve good imaging quality.

[0151] like Figure 14 , which is an explanation of the assembly process of the periscope camera module of the preferred embodiment of the present invention, wherein the periscope camera module includes the light deflection device 10 and the module assembly 20; the optical lens 22 is installed on the carrier 231 of the driving component 23, and the optical lens 22 and the carrier 231 have an integrated structure, and the integrated structure of the optical lens 20 and the carrier 231 is assembled on the support 214 of the photosensitive component 21 to form the module assembly 20.

[0152] Specifically, in a preferred embodiment of this preferred embodiment of the present invention, the assembly process of the periscope camera module 1 is as follows: in order to simulate the effect of real photography, first, the position relationship between the light deflection device 10 and the photosensitive component 20 is preset, specifically, the light deflection unit 11 of the light deflection component 10 is preset to remain in the photosensitive path of the photosensitive component 20, or the geometric center of the light deflection unit 11 of the light deflection component 10 is preset to be located in the photosensitive path of the photosensitive component 20, and then the installation position between the first sub-lens 221 and the second sub-lens (222, 222A) of the optical lens 20 is calibrated. After adjusting the installation position between the second sub-lens (222, 222A) and the first sub-lens 221, the installation position between the optical lens 22 and the photosensitive component 21 is adjusted. More specifically, the installation position between the optical lens 22 and the photosensitive component 21 is AA adjusted, thereby forming a periscope camera module 20.

[0153] In another variant embodiment of the preferred embodiment of the present invention, the assembly process of the periscope camera module 1 is as follows: first, the optical lens 22 and the carrier 231 having an integrated structure are assembled on the photosensitive component 21 to form the module assembly 20. The module assembly 20 is powered on, and the installation position between the first sub-lens 221 and the second sub-lens (222, 222A) of the optical lens 22 is calibrated to obtain the optical lens 22. After adjusting the installation position between the optical lens 22 and the photosensitive component 21, in order to simulate the effect of real photography, the light deflection unit 11 of the light deflection device 10 is set in the light-sensitive path of the photosensitive component 21, and the installation position between the optical lens 22 and the photosensitive component 21 is adjusted. More specifically, the installation position between the optical lens 22 and the photosensitive component 21 is adjusted by AA, thereby forming the periscope camera module 20.

[0154] In another variant embodiment of the preferred embodiment of the present invention, the assembly process of the periscope camera module 1 is as follows: first, the optical lens 22 and the carrier 231 having an integrated structure are assembled on the photosensitive component 21 to form the module assembly 20. The module assembly 20 is powered on, and the installation position between the first sub-lens 221 and the second sub-lens (222, 222A) of the optical lens 22 is calibrated to obtain the optical lens 22. After adjusting the installation position between the optical lens 22 and the photosensitive component 21, the installation position between the optical lens 22 and the photosensitive component 21 is adjusted. More specifically, the installation position between the optical lens 22 and the photosensitive component 21 is adjusted AA to obtain the module assembly 20. Then, the light deflection unit 11 of the light deflection device 10 is set in the light-sensitive path of the photosensitive component 21, thereby obtaining the periscope camera module 1.

[0155] Similarly, in another variant of the preferred embodiment of the present invention, the assembly process of the periscope camera module 1 is as follows: to simulate the effect of real-life photography, the positional relationship between the light deflection device 10 and the photosensitive component 20 is first preset. Specifically, the light deflection unit 11 of the light deflection component 10 is preset to remain in the photosensitive path of the photosensitive component 20, or the geometric center of the light deflection unit 11 of the light deflection component 10 is preset to be located in the photosensitive path of the photosensitive component 20. The optical lens 22 is mounted on the carrier 231 of the driving component 23. The optical lens 22 and the carrier 231 have an integrated structure. The integrated structure of the optical lens 20 and the carrier 231 is assembled to the support 214 of the photosensitive component 21 to form the module assembly 20. After the module assembly 20 is powered on, the installation positions of the first sub-lens 221, the second sub-lens (222, 222A) and the photosensitive component 21 are adjusted simultaneously. In particular, the installation positions of the first sub-lens 221, the second sub-lens (222, 222A) and the photosensitive component 21 are adjusted simultaneously by AA, so as to obtain a higher quality module assembly 20, thereby forming the periscope camera module 1.

[0156] It is worth mentioning that, in the process of performing AA on the installation position between the optical lens 22 and the photosensitive component 21, the optical lens 22 of the driving element 232 of the driving component 23 is optically calibrated relative to the photosensitive component 22. The optical calibration includes autofocus (AF) calibration and optical image stabilization (OIS) calibration. The optical lens 22 is assembled using a split lens, including a first sub-lens 221 and a second sub-lens 222, which reduces the cumulative tolerance of the lens assembly, so that the position between each component can be determined during assembly, thereby obtaining better assembly accuracy. In addition, the optical lens 22 assembled by the first sub-lens 221 and the second sub-lens 222 can reduce the movement stroke of the driving element 232 of the driving component 23, which will reduce the tolerance space for the movement of the optical lens 22 and the reserved space for the installation of the optical lens 22; it can also reduce the driving current of the driving element 232 and reduce the size of the driving circuit board 233.

[0157] The pre-assembled module assembly 20 is powered on to capture an image of the pre-assembled module assembly 20. The image capture of the module assembly 20 is based on the module assembly photographing an MTF test target. The MTF value is used to characterize the image quality of the module assembly 20. A larger MTF value indicates higher image quality. After each acquisition of the camera module image, the MTF value of the corresponding image is calculated to verify whether the MTF value exceeds the standard requirement. If the MTF value is greater than or equal to the standard requirement, the acquisition or adjustment is complete. If the MTF value is less than the standard requirement, re-acquisition and adjustment are required.

[0158] Calculating the MTF value based on the collected image and determining the adjustment amount of the installation position of the first sub-lens 221, the second sub-lens 222 and the photosensitive component 21;

[0159] Using the calculated adjustment amount, the installation positions of the first sub-lens 221 and the second sub-lens 222 and the installation positions of the optical lens 22 and the photosensitive component 21 are actively calibrated respectively; each time an adjustment is made, an imaging image of the pre-assembled module component 20 is collected until the pre-assembled module component 20 is adjusted to meet the resolution requirements.

[0160] After the pre-assembled camera module 20 meets the resolution requirements, the glue between the installation positions of the first sub-lens 221 and the second sub-lens 222 and the installation positions of the second sub-lens 222 and the photosensitive component 23 is completely cured to obtain a module assembly 20 that meets the imaging requirements.

[0161] It is worth noting that during each image acquisition process, the shooting environment parameters of the module assembly 20 must be strictly controlled, including the distance between the test standard and the module assembly 20, the light source parameters, etc., to ensure the accuracy and consistency of image acquisition and facilitate the adjustment of the relative position between the optical lenses 22.

[0162] During the image acquisition process of the module assembly 20 , in addition to calculating the MTF value, other characteristics of the module assembly can also be monitored, including dirty spots, distortion, dark corners, etc.

[0163] The adjustment of the installation position of the first sub-lens 221 and the second sub-lens 222 and the installation position of the optical lens 22 and the photosensitive component 21 is based on the study of the sensitivity of the lens optical design. The method for calculating the adjustment amount of the installation position of the first sub-lens 221 and the second sub-lens 222 and the installation position of the second sub-lens 222 and the photosensitive component 23 through software includes: measuring the optical characteristics of the module component before adjustment according to the imaging of the module component, including the MTF value, eccentricity, tilt angle and field curvature; and calculating the required adjustment amount of the installation position of the first sub-lens 221 and the second sub-lens 222 and the installation position of the optical lens 22 and the photosensitive component 21 according to the sensitivity of the installation position of the first sub-lens 221 and the second sub-lens 222 and the installation position of the optical lens 22 and the photosensitive component 21 to the optical characteristics.

[0164] The adjustment of the installation position of the first sub-lens 221 and the second sub-lens 222 and the installation position of the optical lens 22 and the photosensitive component 23 includes the assembly position of the first sub-lens 221, the second sub-lens 222 and the optical lens 22 and the photosensitive component 21 relative to the photosensitive component 21 in any direction such as horizontal, vertical, and tilt. In other words, the assembly position between the module components 20 can be adjusted along any direction such as horizontal, vertical, tilt, and rotation to improve the imaging quality of the module component 20.

[0165] like Figure 15 As shown in the figure, it is an illustration of the periscope camera module used for the array camera module in the preferred embodiment of the present invention, wherein the array camera module includes an array camera module 1 and an upright camera module 2, so as to form the periscope optical variable module with different assembly layouts by combining the upright camera module 2 and the periscope camera module 1, and enable the periscope optical variable module to have the function of "optical zoom".

[0166] It is worth mentioning that although in the existing periscope array module, the telephoto camera module is installed in a "horizontal" manner to reduce the height difference between the telephoto camera module and the wide-angle camera module to facilitate the assembly of the periscope array module, but with the increase in demand for optical zoom ratio, the telephoto camera module needs to increase the focal length, and accordingly the lens size of the telephoto camera module becomes larger, so that the height of the telephoto camera module will also become larger, which causes the height of the telephoto camera module installed horizontally to still be higher than the height of the wide-angle camera module. Therefore, the existing periscope array modules on the market all have 2x or 3x optical zoom, and it is difficult to achieve a higher optical zoom ratio.

[0167] However, in the array camera module 1 provided by the present invention, the equivalent focal length f1 of the upright camera module 2 is set to be smaller than the equivalent focal length f2 of the periscope camera module 1. Accordingly, the field of view FOV1 of the upright camera module 2 is larger than the field of view FOV2 of the periscope camera module 1. That is, in the present invention, Figure 15 As shown, the upright camera module 2 is configured as a wide-angle camera module, the periscope camera module 1 is configured as a telephoto camera module, and the optical zoom ratio of the periscope array module 1 can reach 2 times or more without increasing the overall size of the periscope array module 1. Preferably, the optical zoom ratio of the periscope array module 1 is implemented as 5 times.

[0168] It is worth mentioning that, in the invention, the upright camera module 2 can be arranged on one side of the light deflection device 10 close to the periscope camera module 1 to form a Figure 15 The periscope array camera module shown; the upright camera module 10 can also be arranged on one side of the photosensitive chip close to the periscope camera module 20 to form a Figure 16 During the assembly process of the array camera module, the upright camera module 2 and the periscope camera module 1 can be actively calibrated simultaneously to ensure that the assembled array camera module has higher assembly accuracy and better consistency.
