Description

Motor assembly and assembling method thereof, camera module and electronic device

[0001] The present application claims priority to the Chinese patent application No. 202411088730.1, filed on August 8, 2024, entitled "Motor assembly and assembling method thereof, camera module and electronic device", the entire content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to the technical field of camera modules, in particular to a motor assembly and an assembling method thereof, a camera module and an electronic device. BACKGROUND

[0003] In order to balance focal length and module height, camera modules (CCM) are increasingly developing towards multi-group lenses. When assembling the lens groups, ultraviolet (UV) heat curing glue is usually used to bond and install the lens groups, and pre-curing is performed by UV pen lamp irradiation to preliminarily fix the lens groups. However, due to the various forms of camera modules and the need for multi-lens group installation, there is a situation where the UV glue is blocked and cannot be irradiated by the UV pen lamp, thereby making it difficult for the UV glue to achieve pre-curing. SUMMARY

[0004] The present application provides a motor assembly and an assembling method thereof, a camera module and an electronic device. The motor assembly includes a motor, a first lens, and curing glue. By providing a light-transmitting structure on the first lens, the UV pen lamp can irradiate ultraviolet rays on one side of the first lens and enter the position where the curing glue is located through the light-transmitting structure to achieve pre-curing of the glue layer, which is conducive to forming the curing glue that bonds the first lens and the motor.

[0005] In a first aspect, the present application provides a motor assembly. The motor assembly includes a motor, a first lens, and curing glue. The motor includes a first face and a second face arranged oppositely, and the motor is provided with a mounting space, the mounting space forms an opening at the first face and the second face, and the side wall of the mounting space has a fixing face, the fixing face faces the opening of the mounting space at the second face. The first lens includes a first lens barrel and a first lens group, and the first lens group is installed on the first lens barrel. The first lens barrel includes a first surface and a second surface arranged oppositely, and the first lens barrel is provided with a light-transmitting structure, the light-transmitting structure forms a first opening at the first surface and a second opening at the second surface, and the second opening communicates with the mounting space. The curing glue is fixedly connected to the first surface and the fixing face, and the curing glue covers the light-transmitting structure.

[0006] In the present application, by setting the light-transmitting structure, after the first surface of the first lens barrel is coated with the curing glue and attached to the fixed surface during the process of installing the first lens barrel to the motor, light can be irradiated from the second surface side of the first lens barrel. The light can be irradiated into the light-transmitting structure from the second sub-space and irradiated to the curing glue, so that the curing glue is cured, thereby realizing the fixed connection between the first lens barrel and the motor.

[0007] In the present application, due to the design of the light-transmitting structure, the light can be irradiated to the curing glue by vertical irradiation or inclined irradiation, overcoming the problem that the light cannot be irradiated from the four sides of the curing glue due to the shielding of the motor. Specifically, by setting the light-transmitting structure on the first lens barrel, and the first opening of the light-transmitting structure is covered by the curing glue, and the second opening of the light-transmitting structure is communicated to the second sub-space, so that the light can be irradiated from the second sub-space to the second opening, and then irradiated to the curing glue through the first opening, thereby realizing the light irradiation to the curing glue, and further realizing the pre-curing or curing of the curing glue, which is conducive to the curing glue forming a bonding layer to bond the first lens and the motor.

[0008] In some possible implementation manners, a ratio of a total area of the first opening covered by the curing glue to a total area of a normal projection of the curing glue on the first surface is within a range from 10% to 50%.

[0009] In the present implementation manner, the first opening and the curing glue are designed as described above, which is conducive to the curing glue being fully irradiated by the light, thereby being conducive to the pre-curing / curing of the curing glue, so as to realize the connection between the first lens and the motor. In addition, the total area of the first opening is limited, avoiding the total area of the first opening being too large, thereby avoiding too many hollow light-transmitting structures being arranged in the first lens barrel, and further ensuring that the first lens barrel has sufficient structural strength.

[0010] In some possible implementation manners, the first surface has a glue coating area, the glue coating area is arranged around the first lens group, at least part of the first opening is located in the glue coating area, and the curing glue is arranged in the glue coating area.

[0011] In the present implementation manner, the glue coating area is used to coat the curing glue to form the curing glue. Since the glue coating area is arranged around the first lens group, the curing glue is arranged around the first lens group, which is conducive to the stability of the curing glue bonding the first lens and the motor. At least part of the first opening is located in the glue coating area, so that the curing glue can cover at least part of the first opening, thereby being conducive to the light irradiating to the curing glue, and further being conducive to the pre-curing or curing of the curing glue.

[0012] In some possible implementation manners, the first lens barrel further has an outer peripheral side surface connected between the first surface and the second surface. The light-transmitting structure is a through hole penetrating through the first surface and the second surface.

[0013] In the present implementation, the through hole has a simple structure, which is conducive to design and manufacture.

[0014] In some other possible implementations, the light-transmitting structure is a slit, and the slit penetrates the first surface, the second surface and the peripheral side surface.

[0015] In the present implementation, the light-transmitting structure is a slit, which is conducive to the design of the first lens with a small size.

[0016] In some possible implementations, when the light-transmitting structure is a through hole, the first opening is circular, and the diameter of the first opening is in a range of 0.05 mm to 0.8 mm.

[0017] In the present implementation, the first opening is circular, which is conducive to simplifying the preparation of the light-transmitting structure. The diameter of the first opening meets the above range, so that the size of the first opening is large enough to enable the curing glue at each first opening to be fully illuminated, which is conducive to the pre-curing / curing of the curing glue. At the same time, the size of the first opening is not too large, which can avoid the curing glue flowing into the light-transmitting structure through the first opening, thereby avoiding the insufficient bonding between the first lens and the motor due to the lack of curing glue.

[0018] In some other possible implementations, the first opening is non-circular, and the equivalent circle diameter of the first opening is in a range of 0.05 mm to 1.5 mm, where the equivalent circle is a circumscribed circle of the first opening.

[0019] In the present implementation, the first opening can be non-circular, which is conducive to designing the shape of the first opening according to actual needs. The first opening can have a circumscribed circle regular shape, such as an ellipse, a triangle, a star, a polygon, a direction, a trapezoid, etc. The first opening can also have an irregular shape without a circumscribed circle, such as a polygon with a concave structure. The diameter of the first opening meets the above range, so that the size of the first opening is large enough to enable the curing glue at each first opening to be fully illuminated, which is conducive to the pre-curing / curing of the curing glue. At the same time, the size of the first opening is not too large, which can avoid the curing glue flowing into the light-transmitting structure through the first opening, thereby avoiding the insufficient bonding between the first lens and the motor due to the lack of curing glue.

[0020] In some possible implementations, when the light-transmitting structure is a slit, the first opening is rectangular, and the width of the first opening is in a range of 0.05 mm to 0.8 mm.

[0021] In the present implementation, the diameter of the first opening satisfies the above range, so that the size of the first opening is large enough to enable the curing glue at each first opening to be fully illuminated, facilitating the pre-curing / curing of the curing glue. Meanwhile, the size of the first opening is not too large, which can avoid the curing glue flowing into the light-transmitting structure through the first opening, thereby avoiding the insufficient bonding between the first lens and the motor due to the lack of curing glue.

[0022] In some possible implementations, the first opening is non-rectangular, and the maximum width of the first opening is in the range of 0.05 mm to 1.5 mm.

[0023] In the present implementation, the diameter of the first opening satisfies the above range, so that the size of the first opening is large enough to enable the curing glue at each first opening to be fully illuminated, facilitating the pre-curing / curing of the curing glue. Meanwhile, the size of the first opening is not too large, which can avoid the curing glue flowing into the light-transmitting structure through the first opening, thereby avoiding the insufficient bonding between the first lens and the motor due to the lack of curing glue.

[0024] In some possible implementations, the first lens barrel further has an outer peripheral side surface connected between the first surface and the second surface. The light-transmitting structure is a sawtooth structure that penetrates the first surface, the second surface, and the outer peripheral side surface.

[0025] In the present implementation, the light-transmitting structure adopts the sawtooth structure, which is conducive to the design of the first lens with a large size, to provide more sufficient illumination for the curing glue.

[0026] In some possible implementations, the equivalent circle diameter of the first opening corresponding to each sawtooth is in the range of 0.05 mm to 1.5 mm.

[0027] In the present implementation, the size of the first opening satisfies the above range, so that the size of the first opening is large enough to enable the curing glue at each first opening to be fully illuminated, facilitating the pre-curing / curing of the curing glue. Meanwhile, the size of the first opening is not too large, which can avoid the curing glue flowing into the light-transmitting structure through the first opening, thereby avoiding the insufficient bonding between the first lens and the motor due to the lack of curing glue.

[0028] In some possible implementations, the distance between two adjacent first openings is greater than or equal to 0.15 mm.

[0029] In the present implementation, the interval between the two adjacent first openings satisfies the above relationship, so that there is sufficient interval between the two adjacent light-transmitting structures, avoiding the interval between the two adjacent light-transmitting structures being too small, which results in the structure strength of the first lens barrel being too low between the two adjacent light-transmitting structures. The design of the present embodiment is beneficial to maintaining the overall structural strength of the first lens barrel.

[0030] In some possible implementations, the size of the second opening is greater than the size of the first opening.

[0031] In the present implementation, the two openings of the light-transmitting structure are designed according to the above structure, so that the first opening has a smaller size, thereby enabling the same area of the curing glue to bond with a larger area of the first surface, which is beneficial to the stability of the curing glue bonding the first lens and the motor. In addition, since the second opening has a larger size, more light can enter the light-transmitting structure, which is beneficial to the curing of the curing glue during the installation process of the motor assembly. In addition, the light-transmitting structure presents a trapezoidal structure, which plays a role in guiding and converging light, which is beneficial to improving the capacity density of light at the first opening, so as to improve the curing efficiency of the curing glue.

[0032] In some possible implementations, the size of the second opening is equal to the size of the first opening.

[0033] In the present implementation, the light-transmitting structure is installed according to the above structure, so that the light-transmitting structure can present a straight cylinder structure, which is beneficial to simplifying the processing of the light-transmitting structure, improving the processing efficiency of the light-transmitting structure, and reducing the damage risk of the light-transmitting structure to the first lens barrel.

[0034] In some possible implementations, the curing glue is formed by ultraviolet heat curing glue, and the pre-curing of the curing glue can be realized by irradiating ultraviolet light on the curing glue. Specifically, a UV lamp can be arranged on one side of the second surface of the first lens, so that the UV light emitted by the UV lamp enters the light-transmitting structure and irradiates on the curing glue, thereby realizing the pre-curing of the curing glue. This not only realizes the pre-fixing of the first lens and the motor, but also is beneficial to the next assembly of the camera module, and is also beneficial to the more sufficient curing of the curing glue in the further curing process.

[0035] In some possible implementations, the motor includes a housing, the housing includes a first face and a second face, the housing is provided with a mounting space, and the fixing face is located on the housing.

[0036] In some possible implementations, the motor includes a housing and a first zoom assembly, the housing includes a first face and a second face, the housing is provided with an inner cavity, the first zoom assembly is installed in the inner cavity, the first zoom assembly and the housing form a mounting space, the fixing face is located on the first zoom assembly, and the first zoom assembly is configured to drive the first lens to move relative to the housing along the optical axis.

[0037] In the implementation, the first lens can be mounted on the first zoom assembly by the cured glue, so that the first zoom assembly can drive the first lens to move to realize zooming, thereby changing the shooting focal length of the camera module and improving the shooting experience.

[0038] In yet another possible implementation, the motor includes a housing and a first anti-shake assembly, the housing includes a first face and a second face, the housing is provided with an inner cavity, the first anti-shake assembly is mounted in the inner cavity, the first anti-shake assembly and the housing enclose an installation space, the fixing face is located on the first anti-shake assembly, and the first anti-shake assembly is configured to drive the first lens to move in a plane perpendicular to the optical axis of the first lens.

[0039] In the implementation, the first lens can be mounted on the first anti-shake assembly by the cured glue, so that the first anti-shake assembly can drive the first lens to move to realize anti-shake, thereby improving the imaging quality of the camera module.

[0040] In some possible implementations, the motor assembly further includes a second lens, the second lens is mounted in the installation space, and the second lens is located on the object side or the image side of the first lens.

[0041] In a second aspect, the present application provides an assembling method of a motor assembly. The assembling method of the motor includes:

[0042] providing a motor and a first lens, wherein the motor includes a first face and a second face arranged oppositely, the motor is provided with an installation space, the installation space forms an opening on the first face and the second face, a side wall of the installation space has a fixing face, the fixing face faces the opening on the second face of the installation space, the first lens includes a first lens barrel and a first lens group, the first lens group is mounted on the first lens barrel, the first lens barrel includes a first surface and a second surface arranged oppositely, the first lens is provided with a light-transmitting structure, the light-transmitting structure forms a first opening on the first surface and a second opening on the second surface;

[0043] applying cured glue on the first surface and covering the light-transmitting structure;

[0044] adhering the first lens barrel to the fixing face by the cured glue, and the second opening is communicated with the installation space; and

[0045] irradiating light on one side of the second surface, the light enters the light-transmitting structure from the installation space and irradiates on the cured glue, and the cured glue is cured to form cured glue.

[0046] In the present application, the first lens is provided with a light-transmitting structure to enable the light to directly irradiate the curing glue from the light-transmitting structure on the side of the second surface, thereby overcoming the problem that the curing glue is blocked around and cannot be irradiated from the periphery. In the present embodiment, the vertical or inclined irradiation can be incident on the light-transmitting glue, thereby improving the convenience of curing the curing glue by irradiation.

[0047] In some possible implementation manners, the light is irradiated on the side of the second surface, the light enters the light-transmitting structure from the mounting space, and irradiates the curing glue. The curing glue is cured to form a cured glue.

[0048] The light is irradiated on the side of the second surface, the light enters the light-transmitting structure from the mounting space, and irradiates the curing glue, so as to pre-cure the curing glue.

[0049] The pre-cured curing glue is heated to be completely cured to form a cured glue.

[0050] In the present implementation manner, after the curing glue is irradiated by the light, the pre-curing of the curing glue can be realized. At this time, the first lens can be stably fixed to the motor, and the motor, the first lens and the second lens can be taken down from the fixing device in the AA process to perform other processes. The light emitted by the light source can enter the mounting space from the interval space between the second fixing clamp and the motor, and be incident on the curing glue from the light-transmitting structure. By using heating or the like, the pre-cured curing glue can be further cured, so that the curing glue can be completely cured to form a cured glue, and the assembly of the motor assembly is completed.

[0051] In some possible implementation manners, before the curing glue is coated on the first surface and covers the light-transmitting structure, the assembly method of the motor assembly further includes:

[0052] providing the second lens, and mounting the second lens in the mounting space; and

[0053] fixing the motor and the second lens.

[0054] In the present implementation manner, the first lens and the second lens are mounted and assembled by the AA process through active alignment, so as to ensure the assembly precision. Specifically, the first fixing clamp can be used to fix the motor and the second lens, and the second fixing clamp can be used to fix the first lens.

[0055] In some possible implementation manners, before the light is irradiated on the side of the second surface, the light enters the light-transmitting structure from the mounting space, and irradiates the curing glue, and the curing glue is cured to form a cured glue, after the first lens is bonded to the fixing surface by the curing glue, and the second opening is communicated with the mounting space, the assembly method of the motor assembly further includes:

[0056] The sensor is provided and fixed, wherein the first lens, the second lens and the sensor are arranged in sequence, or the second lens, the first lens and the sensor are arranged in sequence; and

[0057] According to the imaging of the sensor, the position of the first lens is adjusted so that the optical axis of the first lens coincides with the optical axis of the second lens.

[0058] In the present embodiment, the sensor can be a golden sensor, which provides a calibrated reference to adjust the position of the first lens relative to the second lens. At this time, since the curing glue has not yet cured, the position of the first lens relative to the motor and the second lens can be changed by moving the second fixing clamp, so as to realize dynamic calibration, so that the optical axis of the first lens can coincide with the optical axis of the second lens. In addition, the sensor can also be used for calibration of other parameters to ensure the consistency of the camera module calibrated by the sensor in imaging effect.

[0059] In addition, an equivalent mirror can be arranged between the second lens and the sensor, which can be used to realize specific optical effects, such as focal length conversion, spot shaping, chromatic aberration correction, etc. The equivalent mirror simplifies the design of the optical system, thereby reducing the difficulty and cost of the AA process.

[0060] In some possible implementations, the curing glue is ultraviolet heat-curing glue, and light is irradiated from one side of the second surface, the light entering the light-transmitting structure from the mounting space, comprising:

[0061] UV light is irradiated from one side of the second surface, the UV light entering the second opening from the mounting space and exiting from the first opening to the curing glue.

[0062] In the present embodiment, the light source can be a UV lamp, so that the UV light emitted by the UV lamp enters the light-transmitting structure and irradiates onto the curing glue, thereby realizing the pre-curing of the curing glue and realizing the pre-fixing of the first lens and the motor.

[0063] In a third aspect, the present application provides a camera module. The camera module comprises an image sensor and any of the motor assemblies as described above, and the image sensor is located on the image side of the first lens of the motor assembly.

[0064] In the present application, due to the design of the light-transmitting structure, the pre-curing installation of the motor assembly is facilitated, thereby improving the installation efficiency of the motor assembly and further improving the installation efficiency of the camera module.

[0065] In a fourth aspect, the present application provides an electronic device. The electronic device comprises a shell and any of the camera modules as described above, and the camera module is installed in the shell.

[0066] In the present application, due to the design of the light-transmitting structure, the pre-solidification installation of the motor assembly is facilitated, thereby improving the installation efficiency of the motor assembly, and further improving the installation efficiency of the camera module, so as to improve the installation efficiency of the electronic device.

The light-transmitting panel 2001, the cover plate 3001, and the frame 3002 form an internal accommodating space of the electronic device 1000. The display screen 2002 is accommodated in the internal accommodating space. The cover plate 3001 can be made of metal, plastic, glass, or the like. The cover plate 3001 can be a single material plate or a plate structure formed by splicing multiple plates made of multiple materials.

[0107] The camera module 100 is configured to capture photos and / or videos. In an example, the camera module 100 is installed in the housing 300 and located in the internal accommodating space of the electronic device 1000. The camera module 100 can be used as a rear camera. For example, the light-incident surface of the camera module 100 faces the camera decoration 3003. The camera decoration 3003 is configured to protect the camera module 100.

[0108] In some embodiments, the camera decoration 3003 protrudes to the side of the cover plate 3001 away from the light-transmitting panel 2001. In this way, the camera decoration 3003 can increase the installation space 11 of the camera module 100 in the thickness direction of the electronic device 1000. In other embodiments, the camera decoration 3003 can be flush with the cover plate 3001 or recessed into the internal accommodating space of the electronic device 1000.

[0109] The camera decoration 3003 is provided with a light-transmitting hole 3004. The light-transmitting hole 3004 allows light from the scene to enter the light-incident surface of the camera module 100. In other embodiments, the electronic device 1000 can not include the camera decoration 3003. In this case, the cover plate 3001 is no longer provided with the mounting hole, and the light-transmitting hole 3004 is provided on the cover plate 3001. The light-transmitting hole 3004 allows light from the scene to enter the light-incident surface of the camera module 100.

[0110] In some embodiments, the camera module 100 can also be used as a front camera. For example, the light entrance surface of the camera module 100 faces the light-transmitting panel 2001. The display screen 2002 is provided with a light path avoiding hole. The light path avoiding hole allows the scene light to pass through the light-transmitting panel 2001 and then enter the light entrance surface of the camera module 100. In some other embodiments, the electronic device 1000 can further include one or more other camera modules (not shown in the figure), which are not strictly limited in the embodiments of the present application.

[0111] In some embodiments, as shown in FIG. 1B, the electronic device 1000 can further include a circuit board 400 and an image processor 500, which are located in the internal accommodation space of the electronic device 1000, and the image processor 500 is fixed to and electrically connected to the circuit board 400. The image processor 500 is in communication connection with the camera module 100. The image processor 500 is configured to acquire image data from the camera module 100 and process the image data. The communication connection between the camera module 100 and the image processor 500 can include data transmission through electrical connection such as wiring, or data transmission through coupling. It can be understood that the camera module 100 and the image processor 500 can also be in communication connection through other data transmission modes.

[0112] In some embodiments, the electronic device 1000 can further include an analog-to-digital converter (also referred to as an A / D converter, not shown in the figure). The analog-to-digital converter is connected between the camera module 100 and the image processor 500. The analog-to-digital converter is configured to convert the signal generated by the camera module 100 into a digital image signal and transmit the digital image signal to the image processor 500. The digital image signal is processed by the image processor 500, and finally displayed on the screen 200.

[0113] In some embodiments, the electronic device 1000 can further include a memory (not shown in the figure), which is in communication connection with the image processor 500. After the image processor 500 processes the image digital signal, the image is transmitted to the memory, so that the image can be found in the memory at any time when it is needed to view the image and displayed on the screen 200. In some embodiments, the image processor 500 can also compress the processed image digital signal and store it in the memory, so as to save the memory space.

[0114] In some other embodiments, the electronic device 1000 can also not include the screen 200.

[0115] It should be understood that the mounting position of the camera module 100 of the electronic device 1000 shown in FIGS. 1A and 1B is merely illustrative, and the present application does not limit the mounting position of the camera module 100. In some other embodiments, the camera module 100 can also be mounted at other positions of the electronic device 1000, for example, the camera module 100 can be mounted at the upper middle or upper right corner of the back of the electronic device 1000. In some other embodiments, the electronic device 1000 can include a terminal body and an auxiliary component capable of rotating, moving or detaching relative to the terminal body, and the camera module 100 can also be arranged on the auxiliary component.

[0116] Please refer to FIGS. 2A and 2B, FIG. 2A is a structural schematic diagram of the camera module 100 in the electronic device 1000 shown in FIG. 1A in some embodiments; and FIG. 2B is a structural schematic diagram of the camera module 100 in the electronic device 1000 shown in FIG. 1A in some other embodiments.

[0117] In some embodiments, the camera module 100 can include a motor assembly 10, an image sensor 20 and a module bracket 30, and the motor assembly 10 and the image sensor 20 can be mounted on the module bracket 30.

[0118] For example, the motor assembly 10 can include a motor 1, a first lens 2 and a second lens 4. The motor 1 can include a mounting space 11, and the first lens 2 and the second lens 4 can be mounted in the mounting space 11.

[0119] In some examples (please refer to FIG. 2A), the second lens 4, the first lens 2 and the image sensor 20 can be arranged in the optical axis direction in sequence.

[0120] In some other examples (please refer to FIG. 2B), the first lens 2, the second lens 4 and the image sensor 20 can be arranged in the optical axis direction in sequence.

[0121] It should be noted that FIGS. 2A and 2B take the camera module 100 including two lenses as an example for illustration, and the number of lenses in the camera module 100 is not limited, wherein each lens can include one or more lenses.

[0122] Next, the motor assembly 10 in the camera module 100 will be described in detail.

[0123] Please refer to FIGS. 2A and 3, FIG. 3 is a structural schematic diagram of the motor assembly 10 in the camera module 100 shown in FIG. 2A in some embodiments.

[0124] In some embodiments, the motor 1 can include a first surface 12 and a second surface 13 arranged oppositely. The mounting space 11 can form an opening at the first surface 12 and the second surface 13. The side wall of the mounting space 11 can have a fixing surface 14 facing the opening of the mounting space 11 at the second surface 13. The first lens 2 can be bonded to the fixing surface 14 by the curing glue 3.

[0125] For example, the mounting space 11 can include a first sub-space 11a and a second sub-space 11b. In a direction perpendicular to the optical axis of the first lens 2, the size of the first sub-space 11a is smaller than the size of the second sub-space 11b, so that a stepped surface structure is formed at the connection of the first sub-space 11a and the second sub-space 11b, i.e., the fixing surface 14 of the second sub-space 11b is formed to fix the installation of the first lens 2. The first lens 2 is bonded to the fixing surface 14 by the curing glue 3, which can improve the stability of the installation of the first lens 2 in the mounting space 11 of the motor 1.

[0126] In this embodiment, the first lens 2 can include a first lens barrel 21 and a first lens group 22, and the first lens group 22 can be installed in the first lens barrel 21. The first lens barrel 21 can include a first surface 211 and a second surface 212 arranged oppositely. The first lens barrel 21 is provided with a light-transmitting structure 213, which forms a first opening 2131 at the first surface 211 and a second opening 2132 at the second surface 212, and the second opening 2132 communicates with the mounting space 11. The curing glue 3 is fixedly connected to the first surface 211 and the fixing surface 14, and covers the light-transmitting structure 213.

[0127] It should be noted that the curing glue 3 covering the light-transmitting structure 213 means that the orthographic projection of the curing glue 3 on the first surface 211 of the first lens barrel 21 covers at least part of the first opening 2131 of the light-transmitting structure 213 on the first surface 211.

[0128] In this embodiment, by providing the light-transmitting structure 213, during the installation of the first lens 2 on the motor 1, after the first surface 211 of the first lens barrel 21 is coated with the curing glue and adhered to the fixing surface 14, light can be irradiated from the second surface 212 side of the first lens barrel 21. The light can enter the light-transmitting structure 213 from the second sub-space 11b and irradiate the curing glue, so that the curing glue is cured, thereby realizing the fixed connection between the first lens barrel 21 and the motor 1.

[0129] In the prior art, when the lens is bonded to the motor 1 by using the curing glue, light is usually irradiated from the periphery of the curing glue to achieve pre-curing or curing of the curing glue to bond the lens to the motor 1. However, with the diversified forms of the camera module 100, there are cases where the periphery of the curing glue is blocked by the motor 1 and other structures, so that light cannot be irradiated from the periphery of the curing glue for pre-curing or curing. For example, in the scenario shown in FIG. 3, the first lens 2 is located in the second sub-space 11b and is bonded to the fixed surface 14 by the curing glue. Since the bonding position of the curing glue is inside the motor 1, the periphery of the curing glue is blocked, so that light cannot be irradiated from the periphery of the curing glue at this time, which hinders the pre-curing or curing of the curing glue.

[0130] In the present embodiment, the light-transmitting structure 213 is designed to enable light to be irradiated to the curing glue by vertical irradiation or oblique irradiation, overcoming the problem that light cannot be irradiated from the periphery of the curing glue due to the blocking of the motor 1. Specifically, by providing the light-transmitting structure 213 on the first lens barrel 21, the first opening 2131 of the light-transmitting structure 213 is covered by the curing glue, and the second opening 2132 of the light-transmitting structure 213 communicates with the second sub-space 11b, so that light can be irradiated from the second sub-space 11b to the second opening 2132 and then out of the first opening 2131 to the curing glue, thereby achieving light irradiation to the curing glue and further achieving pre-curing or curing of the curing glue, which is conducive to the curing glue forming a bonding layer to bond the first lens 2 to the motor 1.

[0131] The curing glue can be ultraviolet rays (UV) heat-curing glue. By irradiating UV rays to the curing glue, the pre-curing of the curing glue can be achieved. Specifically, a UV lamp can be provided on one side of the second surface 212 of the first lens 2, so that the UV light emitted by the UV lamp enters the light-transmitting structure 213 and is irradiated to the curing glue, thereby achieving pre-curing of the curing glue. This not only enables the first lens 2 to be pre-fixed to the motor 1, but also facilitates the next assembly of the camera module 100 and enables the curing glue to be more fully cured during further curing. For example, after pre-curing the curing glue, other lenses can be installed in the motor assembly 10, or other devices (such as circuit structures) can be installed in the motor assembly 10. After pre-curing the curing glue, the curing glue can be heated to enable it to be fully cured to form a cured glue 3, thereby enabling the first lens 2 to be fixedly installed on the fixed surface 14 of the motor 1.

[0132] Please refer to FIG. 3, FIG. 4A and FIG. 4B, FIG. 4A is a schematic diagram of the structure of the first lens 2 in the motor assembly 10 shown in FIG. 3 in some embodiments; and FIG. 4B is a schematic diagram of the structure of the first lens 2 in the motor assembly 10 shown in FIG. 3 in other embodiments.

[0133] In some embodiments, the size of the second opening 2132 can be greater than the size of the first opening 2131.

[0134] In the present embodiment, the two openings of the light-transmitting structure 213 are designed according to the above structure, so that the first opening 2131 has a smaller size, so that the same area of the cured glue 3 is bonded to a larger area of the first surface 211, which is conducive to the stability of the cured glue 3 bonding the first lens 2 and the motor 1. In addition, since the second opening 2132 has a larger size, it is conducive to more light entering the light-transmitting structure 213, which is conducive to the curing of the cured glue during the installation process of the motor assembly 10. In addition, the light-transmitting structure 213 has a trapezoidal structure, which can guide and converge light, which is conducive to improving the capacity density of light at the first opening 2131, so as to improve the curing efficiency of the cured glue.

[0135] In other embodiments, the size of the second opening 2132 can be equal to the size of the first opening 2131.

[0136] In the present embodiment, the light-transmitting structure 213 is designed according to the above structure, so that the light-transmitting structure 213 can have a straight cylinder structure, which is conducive to simplifying the processing of the light-transmitting structure 213, improving the processing efficiency of the light-transmitting structure 213, and reducing the risk of damage to the first lens barrel 21 during processing of the light-transmitting structure 213.

[0137] In other embodiments, the size of the second opening 2132 can also be smaller than the size of the first opening 2131.

[0138] Please refer to FIG. 3, FIG. 4B and FIG. 5A, FIG. 5A is a top view schematic diagram of the first lens 2 in the motor assembly 10 shown in FIG. 3 in some embodiments.

[0139] In some embodiments, the first surface 211 can have a glue application area 2111, the glue application area 2111 surrounds the first lens group 22, at least part of the first opening 2131 is located in the glue application area 2111, and the cured glue 3 is arranged in the glue application area 2111. Wherein, the glue application area 2111 is schematically shown by a dashed box in FIG. 5A.

[0140] In the embodiment, the glue coating area 2111 is used to coat the curing glue to form the curing glue 3. Since the glue coating area 2111 surrounds the first lens group 22, the curing glue 3 surrounds the first lens group 22, which is conducive to the stability of the curing glue 3 bonding the first lens 2 and the motor 1. At least part of the first opening 2131 is located in the glue coating area 2111, so that the curing glue can cover at least part of the first opening 2131, thereby facilitating the pre-curing or curing of the curing glue.

[0141] It should be noted that the curing glue is coated on the glue coating area 2111, and the curing glue is cured on the coating area to form the curing glue 3 located on the coating area. It can be understood that the curing glue can exactly cover the entire glue coating area 2111, but there are also cases where a small amount of curing glue is located outside the glue coating area 2111 due to coating errors, and / or a small amount of coating area is not coated with curing glue. In the drawings of the present application, the curing glue exactly covers the entire glue coating area 2111, that is, the orthographic projection of the curing glue 3 / curing glue on the first surface 211 coincides with the coating area.

[0142] For example, the ratio of the total area of the first opening 2131 covered by the curing glue 3 to the total area of the orthographic projection of the curing glue 3 on the first surface 211 is in the range of 10% to 50%. In other words, the ratio of the total area of the first opening 2131 located in the glue coating area 2111 to the total area of the glue coating area 2111 is in the range of 10% to 50%. For example, the above-mentioned ratio can be, but is not limited to, 10%, or 15%, or 20%, or 25%, or 30%, or 35%, or 40%, or 45%, or 50%, or other values between 10% and 50%.

[0143] It should be noted that the orthographic projection of the curing glue 3 on the first surface 211 can be illustrated by the dashed box shown in FIG. 5A, that is, the glue coating area 2111 can be used for illustration.

[0144] In the embodiment, the first opening 2131 and the curing glue 3 are designed as described above, which is conducive to the curing glue being fully irradiated by light, thereby facilitating the pre-curing / curing of the curing glue to achieve the connection between the first lens 2 and the motor 1. In addition, the total area of the first opening 2131 is limited to avoid the total area of the first opening 2131 being too large, thereby avoiding too many hollow light-transmitting structures 213 being arranged in the first lens barrel 21, and further ensuring that the first lens barrel 21 has sufficient structural strength.

[0145] The distance between the two adjacent first openings 2131 (see L1 in FIG. 5A) is greater than or equal to 0.15 mm. For example, the value of L1 can be, but is not limited to, 0.15 mm, or 0.16 mm, or 0.17 mm, or 0.18 mm, or 0.19 mm, or 0.2 mm, or 0.21 mm, or 0.22 mm, or 0.23 mm, or 0.24 mm, or other values greater than 0.15 mm. It should be noted that L1 represents the minimum distance between the two adjacent first openings 2131.

[0146] In this embodiment, the distance between the two adjacent first openings 2131 satisfies the above relationship, so that the two adjacent light transmission structures 213 have sufficient spacing, avoiding the distance between the two adjacent light transmission structures 213 being too small, which causes the structural strength of the first lens barrel 21 between the two adjacent light transmission structures 213 to be too low. The design of this embodiment is beneficial to maintaining the overall structural strength of the first lens barrel 21.

[0147] The light transmission structure 213 can be designed in various shapes.

[0148] Please refer to FIGS. 5A and 5B, which are top view schematic diagrams of the first lens barrel 2 in the motor assembly 10 shown in FIG. 3 in some embodiments.

[0149] In some embodiments, the light transmission structure 213 can be a through hole penetrating the first surface 211 and the second surface 212. The through hole has a relatively simple structure, which is beneficial to design and manufacture.

[0150] In some examples (see FIG. 5A), the shape of the first opening 2131 can be circular, which is beneficial to simplify the preparation of the light transmission structure 213.

[0151] The diameter (see D1 in FIG. 5A) of the first opening 2131 can be in the range of 0.05 mm to 0.8 mm. For example, the value of D1 can be, but is not limited to, 0.05 mm, or 0.15 mm, or 0.25 mm, or 0.35 mm, or 0.45 mm, or 0.55 mm, or 0.65 mm, or 0.75 mm, or 0.8 mm, or other values between 0.05 mm and 0.8 mm.

[0152] In this embodiment, the diameter of the first opening 2131 satisfies the above range, so that the size of the first opening 2131 is large enough to enable the curing glue at each first opening 2131 to be fully illuminated, which is beneficial to the pre-curing / curing of the curing glue. At the same time, the size of the first opening 2131 will not be too large, which can avoid the curing glue flowing into the light transmission structure 213 through the first opening 2131, thereby avoiding the insufficient bonding between the first lens barrel 2 and the motor 1 due to the lack of curing glue.

[0153] In some other examples (see FIG. 5B), the first openings 2131 can be non-circular, and the shape of the first openings 2131 can be designed according to actual needs. In some examples, the first openings 2131 can have a circumscribed circle regular shape, such as an ellipse, a triangle, a star, a polygon, a direction, a trapezoid, etc. The first openings 2131 can also have an irregular shape without a circumscribed circle, such as a polygon with an inward recess structure.

[0154] In some examples, when the first openings 2131 have a circumscribed circle, the equivalent circle diameter (see D2 in FIG. 5B) of the first openings 2131 can be in a range from 0.05 mm to 1.5 mm. When the first openings 2131 do not have a circumscribed circle, the maximum straight line length (see D2 in FIG. 5B) of the first openings 2131 can be in a range from 0.05 mm to 1.5 mm. For example, the value of D2 can be, but is not limited to, 0.05 mm, or 0.25 mm, or 0.45 mm, or 0.65 mm, or 0.85 mm, or 1.05 mm, or 1.25 mm, or 1.45 mm, or 1.5 mm, or other values in a range from 0.05 mm to 1.5 mm.

[0155] It should be noted that the equivalent circle diameter is the diameter of the circumscribed circle of the first openings 2131, which is schematically shown by a dashed circle in FIG. 5B.

[0156] In the present embodiment, the diameter of the first openings 2131 satisfies the above range, so that the size of the first openings 2131 is large enough to allow the curing glue at each first opening 2131 to be fully irradiated, which is beneficial to the pre-curing / curing of the curing glue. At the same time, the size of the first openings 2131 is not too large, which can avoid the curing glue flowing into the light-transmitting structure 213 through the first openings 2131, thereby avoiding the insufficient bonding between the first lens 2 and the motor 1 due to the lack of the curing glue.

[0157] Referring to FIGS. 3, 6A and 6B, FIG. 6A is a top view of the first lens 2 in the motor assembly 10 shown in FIG. 3 in some other embodiments, and FIG. 6B is a top view of the first lens 2 in the motor assembly 10 shown in FIG. 3 in some other embodiments. It should be noted that the first lens 2 shown in FIGS. 6A and 6B can include some structural features of the first lens 2 shown in FIGS. 5A and 5B, and the same structural features will not be described herein.

[0158] In some embodiments, the first lens barrel 21 can have a polygonal or circular shape around the first surface 211.

[0159] When the periphery of the first surface 211 of the first lens barrel 21 is polygonal, the glue application area 2111 corresponding to at least part of the edges is provided with the first opening 2131, so that the curing glue can be irradiated by light in multiple directions, thereby facilitating the curing of the curing glue.

[0160] In some embodiments, the glue application area 2111 corresponding to each edge of the periphery of the first surface 211 of the first lens barrel 21 can be provided with the first opening 2131, which facilitates the strengthening of the light irradiation effect on the curing glue, thereby strengthening the curing effect of the curing glue.

[0161] In some embodiments, the plurality of first openings 2131 in the glue application area 2111 corresponding to one edge of the periphery of the first surface 211 of the first lens barrel 21 can be arranged in a non-linear manner, such as the triangular distribution connected by the dashed line shown in FIG. 6A, so that the plurality of regions where the curing glue is irradiated by light can be arranged in a non-linear manner, which facilitates the stability of the bonding between the first lens 2 and the motor 1 after the curing glue is pre-cured / cured. In other embodiments, the plurality of first openings 2131 in the glue application area 2111 corresponding to one edge of the periphery of the first surface 211 of the first lens barrel 21 can also be arranged in a linear manner, which is not limited herein.

[0162] In some embodiments, the plurality of first openings 2131 can be arranged in a central symmetric manner, which facilitates the uniform light irradiation of the curing glue, and facilitates the balanced stability of the connection between the first lens 2 and the motor 1 after the curing glue is cured. In other embodiments, the plurality of first openings 2131 can also be arranged in an asymmetric manner, which is not limited herein.

[0163] When the periphery of the first surface 211 of the first lens barrel 21 is circular, the glue application area 2111 can be circular, which facilitates the stability of the bonding between the first lens 2 and the motor 1 by the curing glue 3.

[0164] In some embodiments, the plurality of first openings 2131 can be uniformly arranged in the glue application area 2111, which facilitates the uniform pre-curing / curing of the curing glue by uniform light irradiation. In other embodiments, the plurality of first openings 2131 can also be arranged in a non-regular manner in the glue application area 2111, which is not limited herein.

[0165] Please refer to FIG. 3, FIG. 7A and FIG. 7B, FIG. 7A is a top view of the first lens 2 in the motor assembly 10 shown in FIG. 3 in some embodiments; and FIG. 7B is a top view of the first lens 2 in the motor assembly 10 shown in FIG. 3 in some embodiments.

[0166] In some embodiments, the first lens barrel 21 may also have an outer peripheral side 214, which connects the first surface 211 and the second surface 212. The light-transmitting structure 213 may be a slit that extends through the first surface 211, the second surface 212, and the outer peripheral side 214. In this embodiment, the light-transmitting structure 213 is a slit, which is beneficial for designing a smaller first lens 2.

[0167] In some examples (see Figure 7A), the first opening 2131 is rectangular, and the width of the first opening 2131 (see L2 in Figure 7A) can be in the range of 0.05 mm to 0.8 mm. For example, the value of L2 can be, but is not limited to, 0.05 mm, or 0.15 mm, or 0.25 mm, or 0.35 mm, or 0.45 mm, or 0.55 mm, or 0.65 mm, or 0.75 mm, or 0.8 mm, or other values ​​between 0.05 mm and 0.8 mm.

[0168] In this embodiment, the diameter of the first opening 2131 meets the above-mentioned range, so that the size of the first opening 2131 is large enough to ensure that the cured adhesive can be fully illuminated at each first opening 2131, which is beneficial to the pre-curing / curing of the cured adhesive. At the same time, the size of the first opening 2131 is not too large, which can prevent the cured adhesive from flowing into the light-transmitting structure 213 through the first opening 2131, thereby avoiding insufficient bonding between the first lens 2 and the motor 1 due to the lack of cured adhesive.

[0169] In other examples (see Figure 7B), the first opening 2131 is non-rectangular, and the maximum width of the first opening 2131 (see L3 in Figure 7B) is in the range of 0.05 mm to 1.5 mm. For example, the value of L3 can be, but is not limited to, 0.05 mm, or 0.25 mm, or 0.45 mm, or 0.65 mm, or 0.85 mm, or 1.05 mm, or 1.25 mm, or 1.45 mm, or 1.5 mm, or other values ​​between 0.05 mm and 1.5 mm.

[0170] In this embodiment, the diameter of the first opening 2131 meets the above-mentioned range, so that the size of the first opening 2131 is large enough to ensure that the cured adhesive can be fully illuminated at each first opening 2131, which is beneficial to the pre-curing / curing of the cured adhesive. At the same time, the size of the first opening 2131 is not too large, which can prevent the cured adhesive from flowing into the light-transmitting structure 213 through the first opening 2131, thereby avoiding insufficient bonding between the first lens 2 and the motor 1 due to the lack of cured adhesive.

[0171] Figure 7B illustrates various shapes of the first opening 2131, but does not limit the shape of the first opening 2131; it is only used for illustration.

[0172] Please refer to FIG. 3, FIG. 8A and FIG. 8B, FIG. 8A is a top view of the first lens 2 in the motor assembly 10 shown in FIG. 3 in some embodiments; FIG. 8B is a top view of the first lens 2 in the motor assembly 10 shown in FIG. 3 in some embodiments.

[0173] In some embodiments, the light-transmitting structure 213 can be a sawtooth structure, which penetrates the first surface 211, the second surface 212 and the peripheral side surface 214. In this embodiment, the light-transmitting structure 213 adopts a sawtooth structure, which is conducive to the design of the first lens 2 with a larger size, so as to provide more sufficient light for the curing glue.

[0174] For example, the equivalent circle diameter (see D3 in FIG. 8A) of the first opening 2131 corresponding to a single sawtooth is in the range of 0.05mm to 1.5mm. For example, the value of D3 can be, but is not limited to, 0.05mm, or 0.25mm, or 0.45mm, or 0.65mm, or 0.85mm, or 1.05mm, or 1.25mm, or 1.45mm, or 1.5mm, or other values between 0.05mm and 1.5mm.

[0175] In this embodiment, the size of the first opening 2131 meets the above range, so that the size of the first opening 2131 is large enough to enable the curing glue at each first opening 2131 to be fully illuminated, which is conducive to the pre-curing / curing of the curing glue. At the same time, the size of the first opening 2131 is not too large, which can avoid the curing glue flowing into the light-transmitting structure 213 through the first opening 2131, thereby avoiding the insufficient adhesion between the first lens 2 and the motor 1 due to the lack of curing glue.

[0176] In this embodiment, the light-transmitting structure 213 can be distributed on part of the peripheral side surface 214 of the first lens barrel 21 (for example, as shown in FIG. 8A), so that the first lens barrel 21 has sufficient structural strength. Alternatively, the light-transmitting structure 213 can also be distributed on all the peripheral side surfaces 214 of the first lens 2 (for example, as shown in FIG. 8B), so that the first lens barrel 21 is provided with sufficient light-transmitting structures 213, thereby facilitating the provision of sufficient light for the curing glue to achieve more efficient curing / pre-curing.

[0200] Next, the assembly method of the motor assembly 10 in some embodiments will be introduced.

[0201] Please refer to FIG. 13, FIG. 14A and FIG. 14B. FIG. 13 is a flowchart of the assembly method of the motor assembly 10 in some embodiments. FIG. 14A is a schematic diagram of applying and curing the glue 3' in step S20 of the assembly method of the motor assembly 10 shown in FIG. 13 in some embodiments. FIG. 14B is a schematic diagram of curing the glue 3' by light transmission structure 213 in steps S30 and S40 of the assembly method of the motor assembly 10 shown in FIG. 13 in some embodiments.

[0202] In some embodiments, the assembly method of the motor 1 can include steps S10, S20, S30 and S40.

[0203] S10, providing a motor 1 and a first lens 2.

[0204] The motor 1 and the first lens 2 can refer to any of the motors 1 and the first lenses 2 provided in the foregoing embodiments. Specifically, the motor 1 can include a first surface 12 and a second surface 13 arranged oppositely, and the motor 1 is provided with a mounting space 11, which is open at the first surface 12 and the second surface 13. The side wall of the mounting space 11 has a fixing surface 14, which faces the opening of the mounting space 11 at the second surface 13. The first lens 2 includes a first lens barrel 21 and a first lens group 22. The first lens group 22 is mounted to the first lens barrel 21, and the first lens barrel 21 includes a first surface 211 and a second surface 212 arranged oppositely. The first lens 2 is provided with a light-transmitting structure 213, which forms a first opening 2131 at the first surface 211 and a second opening 2132 at the second surface 212.

[0205] S20, the curing adhesive 3' is coated on the first surface 211 and covers the light-transmitting structure 213.

[0206] The coating area of the curing adhesive 3' can refer to the adhesive coating area 2111 shown in FIGS. 5A to 8B. By coating the curing adhesive 3' on the adhesive coating area 2111, at least part of the first opening 2131 can be covered, so that the curing adhesive 3' can be irradiated by the light passing through the light-transmitting structure 213.

[0207] S30, the first lens barrel 21 is bonded to the fixing surface 14 by the curing adhesive 3', and the second opening 2132 communicates with the mounting space 11.

[0208] The second opening 2132 communicates with the mounting space 11, so that the light can enter the second opening 2132 from the mounting space 11, and then pass through the light-transmitting structure 213. The light source 2000 can be located outside the mounting space 11, or the light source 2000 can be located inside the mounting space 11 and between the second opening 2132 and the second surface 212, as long as the light emitted by the light source 2000 can enter the light-transmitting structure 213.

[0209] S40, the light is irradiated on one side of the second surface 212, the light enters the light-transmitting structure 213 from the mounting space 11, and irradiates the curing adhesive 3', so that the curing adhesive 3' forms a cured adhesive 3.

[0210] Wherein, since the motor 1 is not shielded at the opening of the second surface 13 on one side of the second surface 212, the light can be irradiated from the opening of the second surface 13 into the mounting space 11, and then into the light-transmitting structure 213 to irradiate and cure the curing glue 3'. It should be noted that in some embodiments, the light irradiates the curing glue 3' to pre-cure the curing glue 3', and then other methods are required to completely cure the curing glue 3' into the cured glue 3. In other embodiments, the light irradiates the curing glue 3' to completely cure the curing glue 3' into the cured glue 3.

[0211] In the present embodiment, since the first lens 2 is provided with the light-transmitting structure 213, the light can be directly irradiated from the light-transmitting structure 213 to the curing glue 3' on one side of the second surface 212, which can overcome the problem that the curing glue 3' is shielded around and cannot be irradiated from around. In the present embodiment, vertical or inclined irradiation can be incident to the light-transmitting glue, which improves the convenience of curing the curing glue 3' by irradiation.

[0212] Please refer to FIG. 15, FIG. 16 and FIG. 17, FIG. 15 is an assembly flowchart of the second lens 4 in the assembly method of the motor assembly 10 shown in FIG. 13; FIG. 16 is an alignment flowchart of the second lens 4 and the first lens 2 in the assembly method of the motor assembly 10 shown in FIG. 13; FIG. 17 is a structure diagram of the alignment of the first lens 2 and the second lens 4 in the assembly method of the motor 1 shown in FIG. 16.

[0213] In some embodiments, before step S20, the assembly method of the motor assembly 10 can further include steps S101 and S102.

[0214] Step S101, providing the second lens 4, and installing the second lens 4 in the mounting space 11.

[0215] Wherein, the second lens 4 can be installed on the object side of the first lens 2 (please refer to FIG. 2A), or the second lens 4 can also be installed on the image side of the first lens 2 (please refer to FIG. 2B). In the present embodiment, the second lens 4 is installed on the object side of the first lens 2.

[0216] Step S102, fixing the motor 1 and the second lens 4.

[0217] Wherein, the installation of the first lens 2 and the second lens 4 is assembled by an active alignment (AA) process to ensure assembly accuracy. Specifically, the first fixing clamp 3000 can be used to fix the motor 1 and the second lens 4, and the second fixing clamp 4000 can be used to fix the first lens 2.

[0218] In some embodiments, in the AA process, the calibration can be assisted by the sensor 5000, specifically, steps S301 and S302 can be adopted after step S30 and before step S40.

[0219] S301, providing the sensor 5000 and fixing the sensor 5000.

[0220] In some embodiments, the first lens 2, the second lens 4 and the sensor 5000 can be arranged in sequence, or the second lens 4, the first lens 2 and the sensor 5000 can be arranged in sequence. In this embodiment, the second lens 4, the first lens 2 and the sensor 5000 are arranged in sequence.

[0221] In some embodiments, the sensor 5000 can be installed by the fixing bracket 6000 to maintain the fixation of the sensor 5000.

[0222] S302, adjusting the position of the first lens 2 according to the imaging of the sensor 5000 to make the optical axis of the first lens 2 coincide with the optical axis of the second lens 4.

[0223] In some embodiments, the sensor 5000 can be a golden sensor, which provides a reference for calibration and adjustment of the position of the first lens 2 relative to the second lens 4. At this time, since the curing glue 3' has not yet cured, the position of the first lens 2 relative to the motor 1 and the second lens 4 can be changed by moving the second fixing clamp 4000, so as to realize dynamic calibration to make the optical axis of the first lens 2 coincide with the optical axis of the second lens 4. In addition, the sensor 5000 can also be used for calibration of other parameters to ensure the consistency of the imaging effect of the camera module 100 calibrated by the sensor 5000.

[0224] In some embodiments, an equivalent mirror 7000 can be arranged between the second lens 4 and the sensor 5000, which can be used to realize specific optical effects, such as focal length conversion, spot shaping, chromatic aberration correction, etc. The equivalent mirror 7000 simplifies the design of the optical system, thereby reducing the difficulty and cost of the AA process.

[0225] Please refer to FIGS. 17-19, FIG. 18 is a flowchart of curing the curing glue 3' in the assembly method of the motor assembly 10 shown in FIG. 13 in some embodiments; FIG. 19 is a flowchart of irradiating light in the assembly method of the motor assembly 10 shown in FIG. 13 in some embodiments.

[0226] In some embodiments, step S40 can include steps S41 and S42.

[0227] S41, irradiate light on one side of the second surface 212, the light enters the light-transmitting structure 213 from the mounting space 11, and irradiates the cured glue 3' to pre-cure the cured glue 3'.

[0228] After the cured glue 3' is irradiated by the light, the pre-curing of the cured glue 3' can be realized, at this time, the first lens 2 can be stably fixed to the motor 1, and the motor 1, the first lens 2 and the second lens 4 can be taken off from the fixing device in the AA process to perform other processes.

[0229] The light emitted by the light source 2000 can enter the mounting space 11 from the interval space between the second fixing clamp 4000 and the motor 1, and be incident on the cured glue 3' from the light-transmitting structure 213.

[0230] S42, heat the pre-cured cured glue 3' to completely cure to form the cured glue 3.

[0231] The pre-cured cured glue 3' can be further cured by heating or the like, so that the cured glue 3' can be completely cured to form the cured glue 3, and the assembly of the motor assembly 10 is completed.

[0232] In some embodiments, the cured glue 3' can be ultraviolet heat-cured glue. Step S40 can include step S411.

[0233] S411, irradiate ultraviolet light on one side of the second surface 212, the ultraviolet light enters the second opening 2132 from the mounting space 11, and is emitted from the first opening 2131 to the cured glue 3'.

[0234] The light source 2000 can be a UV lamp, so that the UV light emitted by the UV lamp enters the light-transmitting structure 213 and irradiates the cured glue 3', thereby realizing the pre-curing of the cured glue 3' and the pre-fixing of the first lens 2 and the motor 1.
