Description

Technical Field

[0001] The present application relates to the technical field of camera modules, and in particular to a motor assembly and an assembly method thereof, a camera module and an electronic device. Background Art

[0002] In order to take into account both focal length and module height, the camera module (Camera Compact Module, CCM) has increasingly developed lenses in multiple groups. When assembling the lens group, ultraviolet rays (UV) thermosetting glue is usually used to bond and install the lens group, and pre-cured by UV pen light to initially fix the lens group. However, due to the diverse forms of camera modules and the need to install multiple lens groups, there is a situation where the UV glue is blocked and cannot be irradiated by the UV pen light, making it difficult to pre-cure the UV glue. Summary of the invention

[0003] The present application provides a motor assembly and an assembly method thereof, a camera module and an electronic device. The motor assembly includes a motor, a first lens and a curing glue. By setting a light-transmitting structure on the first lens, a UV pen lamp can irradiate ultraviolet rays on one side of the first lens, and the ultraviolet rays are incident on the position of the curing glue through the light-transmitting structure to achieve pre-curing of the glue layer, which is conducive to forming a curing glue that bonds the first lens and the motor.

[0004] In a first aspect, the present application provides a motor assembly. The motor assembly includes a motor, a first lens, and a curing glue. The motor includes a first surface and a second surface disposed in a back-to-back manner, the motor is provided with an installation space, the installation space forms an opening on the first surface and the second surface, and the side wall of the installation space has a fixed surface, the fixed surface faces the opening of the installation space on the second surface. The first lens includes a first lens barrel and a first lens group, and the first lens group is mounted on the first lens barrel. The first lens barrel includes a first surface and a second surface disposed in a back-to-back manner, the first lens barrel is provided with a light-transmitting structure, the light-transmitting structure forms a first opening on the first surface, and forms a second opening on the second surface, and the second opening is connected to the installation space. The curing glue is fixedly connected to the first surface and the fixed surface, and the curing glue covers the light-transmitting structure.

[0005] In the present application, a light-transmitting structure is provided so that during the process of installing the first lens onto the motor, after the first surface of the first lens barrel is coated with curing glue and adhered to the fixing surface, light can be irradiated from the second surface side of the first lens barrel. The light can be emitted into the light-transmitting structure from the second subspace and irradiated to the curing glue, so that the curing glue is cured, thereby achieving a fixed connection between the first lens barrel and the motor.

[0006] In the present application, due to the design of the light-transmitting structure, light can be irradiated to the curing glue by vertical or oblique irradiation, thus overcoming the problem that light cannot be irradiated from all sides of the curing glue due to the obstruction of the motor. Specifically, by arranging a light-transmitting structure on the first lens barrel, and the first opening of the light-transmitting structure is covered by the curing glue, the second opening of the light-transmitting structure is connected to the second subspace, so that light can be irradiated from the second subspace to the second opening, and then emitted to the curing glue through the first opening, thereby realizing light irradiation to the curing glue, and then realizing pre-curing or curing of the curing glue, which is conducive to the curing glue forming an adhesive layer to bond the first lens and the motor.

[0007] In some possible implementations, a ratio of a total area of ​​the first openings covered by the curing adhesive to a total area of ​​an orthographic projection of the curing adhesive on the first surface is in a range of 10% to 50%.

[0008] In this implementation, the first opening and the curing glue 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 and the motor. In addition, the total area of ​​the first opening is limited to avoid the total area of ​​the first opening being too large, thereby avoiding too many hollow light-transmitting structures in the first lens barrel, thereby ensuring that the first lens barrel has sufficient structural strength.

[0009] In some possible implementations, the first surface has a glue-coated area, the glue-coated area is arranged around the first lens group, at least a portion of the first opening is located in the glue-coated area, and the curing glue is arranged in the glue-coated area.

[0010] In this implementation, the glue coating area is used to apply curing glue to solidify and form curing glue. Since the glue coating area is arranged around the first lens group, so that the curing glue is arranged around the first lens group, it is beneficial to the stability of the curing glue bonding the first lens and the motor. Among them, at least a part of the first opening is located in the glue coating area, so that the curing glue can cover at least a part of the first opening, so as to facilitate the light irradiation to the curing glue, and then facilitate the pre-curing or curing of the curing glue.

[0011] In some possible implementations, the first lens barrel further has an outer peripheral side surface, and the outer peripheral side surface is connected between the first surface and the second surface. The light-transmitting structure is a through hole, and the through hole passes through the first surface and the second surface.

[0012] In this implementation, the structure of the through hole is relatively simple, which is convenient for design and production.

[0013] In some other possible implementations, the light-transmitting structure is a slit, and the slit runs through the first surface, the second surface and the peripheral side surface.

[0014] In this implementation, the light-transmitting structure adopts a slit, which is conducive to designing a first lens with a smaller size.

[0015] In some possible implementations, when the light-transmitting structure is a through hole, the first opening is circular, and a diameter of the first opening is in a range of 0.05 mm to 0.8 mm.

[0016] In this implementation, the first opening is circular, which is conducive to simplifying the preparation of the light-transmitting structure. The diameter of the first opening satisfies the above range, so that the size of the first opening is large enough, so that the curing glue can be fully illuminated at each first opening, which is conducive to the pre-curing / curing of the curing glue. At the same time, the size of the first opening will not be too large, which can prevent the curing glue from flowing into the light-transmitting structure through the first opening, thereby avoiding the lack of curing glue causing insufficient bonding between the first lens and the motor.

[0017] In some other possible implementations, the first opening is non-circular, the value of the equivalent circle diameter of the first opening is in the range of 0.05 mm to 1.5 mm, and the equivalent circle is the circumscribed circle of the first opening.

[0018] In this implementation, the first opening may be non-circular, which is conducive to designing the shape of the first opening according to actual needs. Among them, the first opening may be a regular shape with a circumscribed circle, such as an ellipse, a triangle, a star, a polygon, a direction, a trapezoid, etc. The first opening may also be an irregular shape without a circumscribed circle, such as a polygon with a concave structure. 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 to be fully illuminated at each first opening, which is conducive to the pre-curing / curing of the curing glue. At the same time, the size of the first opening will not be too large, which can prevent the curing glue from flowing into the light-transmitting structure through the first opening, thereby avoiding the lack of curing glue and causing insufficient bonding between the first lens and the motor.

[0019] 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 the range of 0.05 mm to 0.8 mm.

[0020] In this implementation, the diameter of the first opening satisfies the above range, so that the size of the first opening is large enough to allow the curing glue to be fully illuminated at each first opening, 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 prevent the curing glue from flowing into the light-transmitting structure through the first opening, thereby preventing the lack of curing glue from causing insufficient bonding between the first lens and the motor.

[0021] In some other possible implementations, the first opening is non-rectangular, and a maximum width of the first opening is in a range from 0.05 mm to 1.5 mm.

[0022] In this implementation, the diameter of the first opening satisfies the above range, so that the size of the first opening is large enough to allow the curing glue to be fully illuminated at each first opening, 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 prevent the curing glue from flowing into the light-transmitting structure through the first opening, thereby preventing the lack of curing glue from causing insufficient bonding between the first lens and the motor.

[0023] In some possible implementations, the first lens barrel further has an outer peripheral side surface, and the outer peripheral side surface is connected between the first surface and the second surface. The light-transmitting structure is a sawtooth structure, and the sawtooth structure runs through the first surface, the second surface and the outer peripheral side surface.

[0024] In this implementation, the light-transmitting structure adopts a sawtooth structure, which is conducive to the design of a first lens with a larger size to provide more sufficient light for curing the glue.

[0025] In some possible implementations, the value of the equivalent circular diameter of the first opening corresponding to a single sawtooth is in the range of 0.05 mm to 1.5 mm.

[0026] In this implementation, the size of the first opening satisfies the above range, so that the size of the first opening is large enough to allow the curing glue to be fully illuminated at each first opening, 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 prevent the curing glue from flowing into the light-transmitting structure through the first opening, thereby preventing the lack of curing glue from causing insufficient bonding between the first lens and the motor.

[0027] In some possible implementations, a distance between two adjacent first openings is greater than or equal to 0.15 mm.

[0028] In this implementation, the spacing between two adjacent first openings satisfies the above relationship, so that there is sufficient spacing between two adjacent light-transmitting structures, avoiding the spacing between two adjacent light-transmitting structures being too small, resulting in the partial structural strength of the first lens barrel between the two adjacent light-transmitting structures being too low. The design of this embodiment is conducive to maintaining the overall structural strength of the first lens barrel.

[0029] In some possible implementations, a size of the second opening is larger than a size of the first opening.

[0030] In this 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, so that the area of ​​the same area of ​​curing glue bonded to the first surface is larger, 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, it is beneficial for more light to enter the light-transmitting structure, which is beneficial to the curing of the curing glue during the installation of the motor assembly. In addition, the light-transmitting structure presents a trapezoidal structure, which plays a role in guiding and converging the light, which is beneficial to increase the energy density of the light at the first opening, so as to improve the curing efficiency of the curing glue.

[0031] In some other possible implementations, the size of the second opening is equal to the size of the first opening.

[0032] In this implementation, the light-transmitting structure is installed with the above-mentioned structural design so that the light-transmitting structure can present a straight tube structure, which is beneficial to simplify the processing of the light-transmitting structure, so as to improve the efficiency of the light-transmitting structure processing and reduce the risk of damage to the first lens barrel during the processing of the light-transmitting structure.

[0033] In some possible implementations, the curing glue is formed by curing the curing glue with ultraviolet light, and the curing glue can be pre-cured by irradiating the curing glue with ultraviolet light. 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 the curing glue, thereby pre-curing the curing glue, which can not only pre-fix the first lens and the motor, which is beneficial to the next step of assembly of the camera module, but also helps the curing glue to be more fully cured during the further curing process.

[0034] In some possible implementations, the motor includes a shell, the shell includes a first surface and a second surface, the shell is provided with an installation space, and the fixing surface is located in the shell.

[0035] In some other possible implementations, the motor includes a shell and a first zoom assembly, the shell includes a first surface and a second surface, the shell is provided with an inner cavity, the first zoom assembly is installed in the inner cavity, the first zoom assembly and the shell are arranged to form an installation space, the fixed surface is located at the first zoom assembly, and the first zoom assembly is used to drive the first lens to move relative to the shell along the optical axis direction.

[0036] In this implementation, the first lens can be installed on the first zoom assembly by curing glue, so that the first zoom assembly can drive the first lens to move to achieve zooming, thereby changing the shooting focal length of the camera module and improving the shooting experience.

[0037] In some other possible implementations, the motor includes a shell and a first anti-shake component, the shell includes a first surface and a second surface, the shell is provided with an inner cavity, the first anti-shake component is installed in the inner cavity, the first anti-shake component and the shell are arranged to form an installation space, the fixed surface is located at the first anti-shake component, and the first anti-shake component is used to drive the first lens to move in a plane perpendicular to the optical axis of the first lens.

[0038] In this implementation, the first lens can be installed on the first anti-shake component by curing glue, so that the first anti-shake component can drive the first lens to move to achieve anti-shake, thereby improving the imaging quality of the camera module.

[0039] In some possible implementations, the motor assembly further includes a second lens, which is installed in the installation space, and the second lens is located on the object side or image side of the first lens.

[0040] In a second aspect, the present application provides a method for assembling a motor assembly. The motor assembly method comprises:

[0041] A motor and a first lens are provided, wherein the motor includes a first surface and a second surface disposed in opposite directions, the motor is provided with an installation space, the installation space forms openings on the first surface and the second surface, a side wall of the installation space has a fixing surface, the fixing surface faces the opening of the installation space on the second surface, 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 disposed in opposite directions, the first lens is provided with a light-transmitting structure, the light-transmitting structure forms a first opening on the first surface, and forms a second opening on the second surface;

[0042] Applying curing glue on the first surface and covering the light-transmitting structure;

[0043] The first lens barrel is bonded to the fixing surface by curing glue, and the second opening is connected to the installation space; and

[0044] Light is irradiated on one side of the second surface, and the light enters the light-transmitting structure from the installation space and irradiates the curing glue, and the curing glue is cured to form a cured adhesive.

[0045] In the present application, since the first lens is provided with a light-transmitting structure, light can be directly irradiated from the light-transmitting structure to the curing glue from one side of the second surface, which can overcome the problem that the curing glue is blocked on all sides and cannot be illuminated from all sides. In this embodiment, the light can be incident on the light-transmitting glue through vertical or oblique illumination, thereby improving the convenience of curing the curing glue by irradiating light.

[0046] In some possible implementations, light is irradiated on one side of the second surface, the light enters the light-transmitting structure from the installation space, and irradiates the curing glue, and the curing glue is cured to form a cured adhesive, including:

[0047] irradiating light on one side of the second surface, the light entering the light-transmitting structure from the installation space and irradiating the curing glue to pre-cure the curing glue; and

[0048] The pre-cured curing glue is heated until it is completely cured to form a cured glue.

[0049] In this implementation, after the curing glue is irradiated with light, the curing glue can be pre-cured. 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 removed from the fixing device in the AA process to perform other processes. The light emitted by the light source can enter the installation space from the gap between the second fixing clamp and the motor, and be incident on the curing glue from the light-transmitting structure. The pre-cured curing glue can be further cured by heating and other methods, so that the curing glue can be completely cured, thereby forming a curing glue and completing the assembly of the motor assembly.

[0050] In some possible implementations, before applying the curing glue on the first surface and covering the light-transmitting structure, the motor assembly assembly method further includes:

[0051] Providing a second lens, and installing the second lens in the installation space; and

[0052] Fix the motor and the second lens.

[0053] In this implementation, the first lens and the second lens are installed and assembled through active alignment and AA process to ensure assembly accuracy. Specifically, the motor and the second lens can be fixed by a first fixing clamp, and the first lens can be fixed by a second fixing clamp.

[0054] In some possible implementations, after the first lens barrel is bonded to the fixing surface by curing glue and the second opening is connected to the installation space, light is irradiated on one side of the second surface, the light enters the light-transmitting structure from the installation space and irradiates the curing glue, and before the curing glue is cured to form a cured adhesive, the assembly method of the motor assembly further includes:

[0055] Providing a sensor and fixing the sensor, wherein a first lens, a second lens, and the sensor are arranged in sequence, or the second lens, the first lens, and the sensor are arranged in sequence; and

[0056] According to the sensor imaging, 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.

[0057] In this implementation, the sensor can use a golden sensor, and the sensor can be used to provide a calibration benchmark and reference to adjust the position of the first lens relative to the second lens. At this time, since the curing glue has not yet solidified, the position of the first lens relative to the motor and the second lens can be changed by moving the second fixing clamp, thereby achieving 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 to calibrate other parameters to ensure the consistency of the imaging effect of the camera module calibrated by the sensor.

[0058] Among them, an equivalent mirror can also be set between the second lens and the sensor, and the equivalent mirror can be used to achieve 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.

[0059] In some possible implementations, the curing glue is an ultraviolet thermosetting glue, and light is irradiated on one side of the second surface, and the light enters the light-transmitting structure from the installation space, including:

[0060] Ultraviolet rays are irradiated on one side of the second surface, and the ultraviolet rays enter the second opening from the installation space and are emitted from the first opening to cure the glue.

[0061] In this implementation, the light source may be a UV lamp, so that the UV light emitted by the UV lamp enters the light-transmitting structure and irradiates the curing glue, thereby pre-curing the curing glue and pre-fixing the first lens and the motor.

[0062] In a third aspect, the present application provides a camera module, which includes an image sensor and any of the motor assemblies described above, wherein the image sensor is located on the image side of a first lens of the motor assembly.

[0063] In the present application, the design of the light-transmitting structure facilitates the pre-curing installation of the motor assembly, thereby improving the installation efficiency of the motor assembly, and further improving the installation efficiency of the camera module.

[0064] In a fourth aspect, the present application provides an electronic device, which includes a housing and any of the aforementioned camera modules, wherein the camera module is mounted on the housing.

[0065] In the present application, the design of the light-transmitting structure facilitates the pre-curing installation of the motor assembly, thereby improving the installation efficiency of the motor assembly, and further improving the installation efficiency of the camera module, thereby improving the installation efficiency of the electronic device.

The cover plate 3001 is provided with a mounting opening, and the camera decoration 3003 covers and is fixed at the mounting opening.

[0106] Exemplarily, the camera module 100 is used to take photos / videos. Exemplarily, the camera module 100 is installed in the housing 300, located in the internal accommodation space of the electronic device 1000. Among them, 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 used to protect the camera module 100.

[0107] 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 also be flush with the cover plate 3001 or recessed into the internal accommodation space of the electronic device 1000.

[0108] The camera decoration 3003 is provided with a light-transmitting hole 3004. The light-transmitting hole 3004 allows the scene light to enter the light-entering surface of the camera module 100. In some other embodiments, the electronic device 1000 may not include the camera decoration 3003. In this case, the cover plate 3001 is no longer provided with a mounting port, and the light-transmitting hole 3004 is provided on the cover plate 3001, and the light-transmitting hole 3004 allows the scene to enter the light-entering surface of the camera module 100.

[0109] In other embodiments, the camera module 100 can also be used as a front camera. For example, the light incident surface of the camera module 100 faces the light-transmitting panel 2001. A light path avoidance hole is provided on the display screen 2002. The light path avoidance hole allows the scene light to pass through the light-transmitting panel 2001 and then enter the light incident surface of the camera module 100. In other embodiments, the electronic device 1000 may also include one or more other camera modules (not shown in the figure), which is not strictly limited in the embodiments of the present application.

[0110] In some embodiments, Figure 1B As shown, the electronic device 1000 may also include a circuit board 400 and an image processor 500, the circuit board 400 and the image processor 500 are located in the internal accommodation space of the electronic device 1000, and the image processor 500 is fixed to the circuit board 400 and electrically connected to the circuit board 400. The image processor 500 is communicatively connected to the camera module 100. The image processor 500 is used to obtain image data from the camera module 100 and process the image data. Among them, the communication connection between the camera module 100 and the image processor 500 may include data transmission through electrical connection methods such as wiring, and data transmission may also be achieved through coupling and other methods. It is understandable that the camera module 100 and the image processor 500 can also achieve communication connection through other methods that can achieve data transmission.

[0111] In some embodiments, the electronic device 1000 may 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 used to convert the signal generated by the camera module 100 into a digital image signal and transmit it to the image processor 500, and then the image processor 500 processes the digital image signal, and finally displays the image or video on the screen 200.

[0112] In some embodiments, the electronic device 1000 may further include a memory (not shown in the figure), which is in communication with the image processor 500. The image processor 500 processes the image digital signal and then transmits the image to the memory, so that when the image needs to be viewed later, the image can be searched from the memory at any time and displayed on the screen 200. In some embodiments, the image processor 500 also compresses the processed image digital signal and stores it in the memory to save memory space.

[0113] In some other embodiments, the electronic device 1000 may not include the screen 200 .

[0114] Understandably, Figure 1A and Figure 1BThe installation position of the camera module 100 of the electronic device 1000 in the illustrated embodiment is merely illustrative, and the present application does not strictly limit the installation position of the camera module 100. In some other embodiments, the camera module 100 may also be installed at other positions of the electronic device 1000, for example, the camera module 100 may be installed at the upper middle or upper right corner of the back of the electronic device 1000. In some other embodiments, the electronic device 1000 may include a terminal body and an auxiliary component that can be rotated, moved or disassembled relative to the terminal body, and the camera module 100 may also be arranged on the auxiliary component.

[0115] Please refer to Figure 2A and Figure 2B , Figure 2A yes Figure 1A A schematic diagram of the structure of the camera module 100 in the electronic device 1000 in some embodiments; Figure 2B yes Figure 1A The structure diagram of the camera module 100 in the electronic device 1000 in other embodiments is shown.

[0116] In some embodiments, the camera module 100 may include a motor assembly 10 , an image sensor 20 , and a module bracket 30 , and the motor assembly 10 and the image sensor 20 may both be mounted on the module bracket 30 .

[0117] Exemplarily, the motor assembly 10 may include a motor 1, a first lens 2, and a second lens 4. The motor 1 may include an installation space 11, and the first lens 2 and the second lens 4 may both be installed in the installation space 11.

[0118] In some examples (see Figure 2A ), the second lens 4, the first lens 2 and the image sensor 20 can be arranged in sequence in the optical axis direction.

[0119] In other examples (see Figure 2B ), the first lens 2, the second lens 4 and the image sensor 20 can be arranged in sequence in the optical axis direction.

[0120] It should be noted that Figure 2A and Figure 2B The camera module 100 includes two lenses as an example, and the number of lenses in the camera module 100 is not limited, wherein each lens may include one or more lenses.

[0121] Next, the motor assembly 10 in the camera module 100 is introduced in detail.

[0122] Please refer to Figure 2A and Figure 3 , Figure 3 yes Figure 2AThe structure diagram of the motor assembly 10 in the camera module 100 in some embodiments is shown.

[0123] In some embodiments, the motor 1 may include a first surface 12 and a second surface 13 disposed in opposite directions. The installation space 11 may form openings on the first surface 12 and the second surface 13. The side wall of the installation space 11 may have a fixing surface 14, and the fixing surface 14 faces the opening of the installation space 11 on the second surface 13. The first lens 2 may be bonded to the fixing surface 14 by a curing adhesive 3.

[0124] Exemplarily, the installation space 11 may include a first subspace 11a and a second subspace 11b. In a direction perpendicular to the optical axis of the first lens 2, the size of the first subspace 11a is smaller than the size of the second subspace 11b, so that a step surface structure is formed at the connection between the first subspace 11a and the second subspace 11b, that is, a fixing surface 14 is formed in the second subspace 11b to fix and install 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 first lens 2 installed in the installation space 11 of the motor 1.

[0125] The first lens 2 may include a first lens barrel 21 and a first lens group 22, and the first lens group 22 may be installed on the first lens barrel 21. The first lens barrel 21 may include a first surface 211 and a second surface 212 disposed opposite to each other. The first lens barrel 21 is provided with a light-transmitting structure 213, and the light-transmitting structure 213 may form a first opening 2131 on the first surface 211, and may form a second opening 2132 on the second surface 212, and the second opening 2132 is connected to the installation space 11. The curing glue 3 is fixedly connected to the first surface 211 and the fixing surface 14, and the curing glue 3 covers the light-transmitting structure 213.

[0126] It should be noted that the curing glue 3 covers the light-transmitting structure 213 , which means that the orthographic projection of the curing glue 3 on the first surface 211 of the first lens barrel 21 covers at least a portion of the first opening 2131 of the light-transmitting structure 213 on the first surface 211 .

[0127] In this embodiment, a light-transmitting structure 213 is provided so that during the process of installing the first lens 2 onto the motor 1, after the first surface 211 of the first lens barrel 21 is coated with curing glue and adhered to the fixing surface 14, light can be irradiated from the second surface 212 of the first lens barrel 21. The light can be emitted into the light-transmitting structure 213 from the second subspace 11b and irradiated to the curing glue, so that the curing glue is cured, thereby realizing a fixed connection between the first lens barrel 21 and the motor 1.

[0128] In the prior art, when using curing glue to bond the lens and the motor 1, light is usually irradiated from all sides of the curing glue to achieve pre-curing or curing of the curing glue, so as to bond the lens and the motor 1. However, as the camera module 100 has various forms, the periphery of the lens is blocked by structures such as the motor 1, so that the periphery of the curing glue is blocked, and it is impossible to irradiate light from all sides of the curing glue for pre-curing or curing. For example, in Figure 3 In the scene shown, the first lens 2 is located in the second subspace 11b, and the first lens 2 is bonded to the fixing surface 14 by means of curing glue. Since the bonding position of the curing glue is in the internal space of the motor 1, the surroundings of the curing glue are blocked, and light cannot be irradiated from all around the curing glue, which hinders the pre-curing or curing of the curing glue.

[0129] In this embodiment, due to the design of the light-transmitting structure 213, light can be irradiated to the curing glue by vertical or oblique irradiation, thus overcoming the problem that light cannot be irradiated from all sides of the curing glue due to the obstruction of the motor 1. Specifically, by arranging the light-transmitting structure 213 on the first lens barrel 21, and the first opening 2131 of the light-transmitting structure 213 is covered by the curing glue, the second opening 2132 of the light-transmitting structure 213 is connected to the second subspace 11b, so that light can be irradiated from the second subspace 11b to the second opening 2132, and then emitted to the curing glue through the first opening 2131, thereby achieving light irradiation to the curing glue, and then achieving pre-curing or curing of the curing glue, which is conducive to the curing glue forming an adhesive layer to bond the first lens 2 and the motor 1.

[0130] Among them, the curing glue can be an ultraviolet (UV) thermosetting glue, and the curing glue can be pre-cured by irradiating ultraviolet rays to the curing glue. Specifically, a UV lamp can be set 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 irradiates the curing glue, thereby achieving pre-curing of the curing glue, which can not only achieve pre-fixation of the first lens 2 and the motor 1, which is beneficial to the next step of assembly of the camera module 100, but also facilitate the curing glue to achieve more sufficient curing during the further curing process. For example, after the curing glue is pre-cured, 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 the curing glue is pre-cured, the curing glue can be heated so that it can be completely cured to form a curing glue 3, thereby achieving the first lens 2 fixedly installed on the fixing surface 14 of the motor 1.

[0131] Please refer to Figure 3 , Figure 4A and Figure 4B , Figure 4A yes Figure 3 The schematic diagram of the structure of the first lens 2 in the motor assembly 10 in some embodiments; Figure 4B yes Figure 3 Schematic diagram of the structure of the first lens 2 in the motor assembly 10 in other embodiments.

[0132] In some embodiments, the size of the second opening 2132 may be larger than the size of the first opening 2131 .

[0133] In this 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 curing glue 3 is bonded to the first surface 211 with a larger area, which is beneficial to the stability of the curing glue 3 bonding the first lens 2 and the motor 1. In addition, since the second opening 2132 has a larger size, it is beneficial for more light to enter the light-transmitting structure 213, which is beneficial to the curing of the curing glue during the installation process of the motor assembly 10. In addition, the light-transmitting structure 213 presents a trapezoidal structure, which plays a role in guiding and converging the light, which is beneficial to improving the energy density of the light at the first opening 2131, so as to improve the curing efficiency of the curing glue.

[0134] In some other embodiments, the size of the second opening 2132 may be equal to the size of the first opening 2131 .

[0135] In this embodiment, the light-transmitting structure 213 is installed with the above-mentioned structural design so that the light-transmitting structure 213 can present a straight tube structure, which is beneficial to simplify the processing of the light-transmitting structure 213, so as to improve the processing efficiency of the light-transmitting structure 213, and can reduce the risk of damage to the first lens barrel 21 caused by the processing of the light-transmitting structure 213.

[0136] In some other embodiments, the size of the second opening 2132 may be smaller than the size of the first opening 2131 .

[0137] Please refer to Figure 3 , Figure 4B and Figure 5A , Figure 5A yes Figure 3 The diagram is a top view of the first lens 2 in the motor assembly 10 in some embodiments.

[0138] In some embodiments, the first surface 211 may have a glue-coated area 2111, the glue-coated area 2111 is arranged around the first lens group 22, at least a portion of the first opening 2131 is located in the glue-coated area 2111, and the curing glue 3 is arranged in the glue-coated area 2111. Figure 5A The dashed box is used for illustration.

[0139] In this embodiment, the glue-coating area 2111 is used to apply curing glue to solidify and form curing glue 3. Since the glue-coating area 2111 is arranged around the first lens group 22, so that the curing glue 3 is arranged around the first lens group 22, it is beneficial to the stability of the curing glue 3 bonding the first lens 2 and the motor 1. Among them, at least a part of the first opening 2131 is located in the glue-coating area 2111, so that the curing glue can cover at least a part of the first opening 2131, so as to facilitate the light irradiation to the curing glue, and further facilitate the pre-curing or curing of the curing glue.

[0140] It should be noted that the curing glue is applied to the glue coating area 2111, and the curing glue is cured in the coating area to form the curing glue 3 located in the coating area. It is understandable that the curing glue can just 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 the curing glue. In the drawings of the present application, it is illustrated that the curing glue just 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.

[0141] Exemplarily, the ratio of the total area of ​​the first openings 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 openings 2131 located in the glue-coated area 2111 to the total area of ​​the glue-coated area 2111 is in the range of 10% to 50%. For example, the above 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%.

[0142] It should be noted that the orthographic projection of the curing glue 3 on the first surface 211 can be Figure 5A The dotted box is used for illustration, that is, the glue-coated area 2111 can be used for illustration.

[0143] In this 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 in the first lens barrel 21, thereby ensuring that the first lens barrel 21 has sufficient structural strength.

[0144] The distance between two adjacent first openings 2131 (see Figure 5AIn the embodiment, L1 is greater than or equal to 0.15 mm. For example, the value of L1 may 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 spacing between two adjacent first openings 2131.

[0145] In this embodiment, the spacing between two adjacent first openings 2131 satisfies the above relationship, so that there is a sufficient spacing between two adjacent light-transmitting structures 213, avoiding that the spacing between two adjacent light-transmitting structures 213 is too small, resulting in the first lens barrel 21 between the two adjacent light-transmitting structures 213 having too low structural strength. The design of this embodiment is conducive to maintaining the overall structural strength of the first lens barrel 21.

[0146] The light-transmitting structure 213 can be designed in various shapes.

[0147] See also Figure 5A and Figure 5B , Figure 5B yes Figure 3 Schematic top view of the first lens 2 in the motor assembly 10 in some other embodiments.

[0148] In some embodiments, the light-transmitting structure 213 may be a through hole, and the through hole passes through the first surface 211 and the second surface 212. The structure of the through hole is relatively simple, which is convenient for design and manufacturing.

[0149] In some examples (see Figure 5A ), the shape of the first opening 2131 can be circular, which is helpful to simplify the preparation of the light-transmitting structure 213.

[0150] The diameter of the first opening 2131 (see Figure 5A The value of D1 in the embodiment of the present invention 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.

[0151] 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 allow the curing glue to be fully illuminated at each first opening 2131, 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 prevent the curing glue from flowing into the light-transmitting structure 213 through the first opening 2131, thereby preventing the lack of curing glue from causing insufficient bonding between the first lens 2 and the motor 1.

[0152] In other examples (see Figure 5B ), the first opening 2131 may be non-circular, which is conducive to designing the shape of the first opening 2131 according to actual needs. Among them, the first opening 2131 may be a regular shape with a circumscribed circle, such as an ellipse, a triangle, a star, a polygon, a direction, a trapezoid, etc. The first opening 2131 may also be an irregular shape without a circumscribed circle, such as a polygon with a concave structure.

[0153] When the first opening 2131 has a circumscribed circle, the equivalent circle diameter of the first opening 2131 (see Figure 5B The value of D2 in is within the range of 0.05 mm to 1.5 mm. When the first opening 2131 has no circumscribed circle, the maximum straight line length of the first opening 2131 (see Figure 5B The value of D2 in the embodiment is in the range of 0.05 mm to 1.5 mm. For example, the value of D2 may 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.

[0154] It should be noted that the equivalent circle diameter is the diameter of the circumscribed circle of the first opening 2131. Figure 5B The dashed circle is used for illustration.

[0155] 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 allow the curing glue to be fully illuminated at each first opening 2131, 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 prevent the curing glue from flowing into the light-transmitting structure 213 through the first opening 2131, thereby preventing the lack of curing glue from causing insufficient bonding between the first lens 2 and the motor 1.

[0156] See also Figure 3 , Fig. 6A and Figure 6B , Fig. 6A yes Figure 3Schematic top view of the first lens 2 in the motor assembly 10 in some other embodiments; Figure 6B yes Figure 3 The schematic top view of the first lens 2 in the motor assembly 10 in some other embodiments is shown. It should be noted that: Fig. 6A and Figure 6B The first lens 2 shown may include Figure 5A and Figure 5B Some structural features of the first lens 2 are shown, and the same structural features are not repeated here.

[0157] In some embodiments, the shape of the periphery of the first lens barrel 21 on the first surface 211 may be polygonal or circular.

[0158] When the periphery of the first lens barrel 21 on the first surface 211 is a polygon, the glue coating area 2111 corresponding to at least part of the sides is provided with a first opening 2131 so that the curing glue can be irradiated by light in multiple directions, thereby facilitating the curing of the curing glue.

[0159] The first lens barrel 21 may be provided with a first opening 2131 in each glue coating area 2111 corresponding to each edge of the periphery of the first surface 211, which is beneficial to enhance the illumination effect on the curing glue, thereby enhancing the curing effect of the curing glue.

[0160] In the glue-coated area 2111 corresponding to one edge of the periphery of the first surface 211 of the first lens barrel 21, the plurality of first openings 2131 may be arranged nonlinearly, for example, as Fig. 6A The triangular distribution connected by the dotted lines shown in the figure enables a nonlinear arrangement between the multiple areas where the curing glue is irradiated by light, which is beneficial to the stability of bonding the first lens 2 and the motor 1 after the curing glue is pre-cured / cured. In some other embodiments, in the glue-coated area 2111 corresponding to one edge of the periphery of the first surface 211 of the first lens barrel 21, the multiple first openings 2131 can also be arranged linearly, which is not limited here.

[0161] Among them, the multiple first openings 2131 can be distributed symmetrically around the center, which is conducive to uniform illumination of multiple locations of the curing glue, and is conducive to the balanced and stable connection between the first lens 2 and the motor 1 after the curing glue is cured. In some other embodiments, the multiple first openings 2131 can also be arranged asymmetrically, which is not limited here.

[0162] When the periphery of the first lens barrel 21 on the first surface 211 is circular, the glue-coated area 2111 may be circular, which is beneficial to the stability of the bonding between the first lens 2 and the motor 1 by the curing glue 3 .

[0163] The plurality of first openings 2131 may be evenly arranged in the glue coating area 2111, which is beneficial for uniform illumination of the curing glue, thereby facilitating uniform pre-curing / curing of the curing glue. In some other embodiments, the plurality of first openings 2131 may also be irregularly arranged in the glue coating area 2111, which is not limited here.

[0164] Please refer to Figure 3 , Fig. 7A and Figure 7B , Fig. 7A yes Figure 3 Schematic top view of the first lens 2 in the motor assembly 10 in some other embodiments; Figure 7B yes Figure 3 Schematic top view of the first lens 2 in the motor assembly 10 in some further embodiments.

[0165] In some embodiments, the first lens barrel 21 may further have an outer peripheral side surface 214, and the outer peripheral side surface 214 is connected between the first surface 211 and the second surface 212. The light-transmitting structure 213 may be a slit, and the slit runs through the first surface 211, the second surface 212 and the outer peripheral side surface 214. In this embodiment, the light-transmitting structure 213 is a slit, which is conducive to the design of a first lens 2 with a smaller size.

[0166] In some examples (see Fig. 7A ), the first opening 2131 is rectangular, and the width of the first opening 2131 (see Fig. 7A The value of L2 in the figure 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.

[0167] 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 allow the curing glue to be fully illuminated at each first opening 2131, 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 prevent the curing glue from flowing into the light-transmitting structure 213 through the first opening 2131, thereby preventing the lack of curing glue from causing insufficient bonding between the first lens 2 and the motor 1.

[0168] In other examples (see Figure 7B ), the first opening 2131 is non-rectangular, and the maximum width of the first opening 2131 (see Figure 7BThe value of L3 in the embodiment is in the range of 0.05 mm to 1.5 mm. For example, the value of L3 may 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.

[0169] 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 allow the curing glue to be fully illuminated at each first opening 2131, 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 prevent the curing glue from flowing into the light-transmitting structure 213 through the first opening 2131, thereby preventing the lack of curing glue from causing insufficient bonding between the first lens 2 and the motor 1.

[0170] in, Figure 7B Various shapes of the first opening 2131 are illustrated, but the shape of the first opening 2131 is not limited and is only used for illustration.

[0172] In some embodiments, the light-transmitting structure 213 may be a sawtooth structure, which passes through 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 curing the glue.

[0173] For example, the equivalent circular diameter of the first opening 2131 corresponding to a single sawtooth (see Fig. 8A The value of D3 in the embodiment is in the range of 0.05 mm to 1.5 mm. For example, the value of D3 may 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.

[0174] In this embodiment, the size of the first opening 2131 satisfies the above range, so that the size of the first opening 2131 is large enough to allow the curing glue to be fully illuminated at each first opening 2131, 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 prevent the curing glue from flowing into the light-transmitting structure 213 through the first opening 2131, thereby preventing the lack of curing glue from causing insufficient bonding between the first lens 2 and the motor 1.

[0175] The light-transmitting structure 213 may be distributed on a portion of the outer peripheral side surface 214 of the first lens barrel 21 (eg Fig. 8A As shown in FIG. 2 ), the first lens barrel 21 has sufficient structural strength. Alternatively, the light-transmitting structure 213 can also be distributed on all peripheral sides 214 of the first lens 2 (for example, Figure 8B As shown), the first lens barrel 21 is provided with enough light-transmitting structures 213, thereby facilitating providing sufficient light for curing the glue, so as to achieve more efficient curing / pre-curing.

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

[0201] Please refer to Fig.13 , Fig.14A and Fig. 14B , Fig.13 is a schematic flow chart of an assembly method of a motor assembly 10 provided in the present application in some embodiments; Fig.14A yes Fig.13 The schematic diagram of step S20 of the assembly method of the motor assembly 10 in some embodiments is a schematic diagram of applying and curing glue 3'; Fig. 14B yes Fig.13 The schematic diagram of steps S30 and S40 in the assembly method of the motor assembly 10 in some embodiments is to cure the glue 3 ′ by irradiating light through the light-transmitting structure 213 .

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

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

[0204] Among them, the motor 1 and the first lens 2 can refer to the motor 1 and the first lens 2 in any of the embodiments provided in the above embodiments. Specifically, the motor 1 may include a first surface 12 and a second surface 13 disposed in a back-to-back manner, and the motor 1 is provided with an installation space 11, and the installation space 11 forms openings on the first surface 12 and the second surface 13. The side wall of the installation space 11 has a fixing surface 14, and the fixing surface 14 faces the opening of the installation space 11 on 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 on the first lens barrel 21, and the first lens barrel 21 includes a first surface 211 and a second surface 212 disposed in a back-to-back manner. The first lens 2 is provided with a light-transmitting structure 213, and the light-transmitting structure 213 forms a first opening 2131 on the first surface 211, and forms a second opening 2132 on the second surface 212.

[0205] S20 , coating the curing glue 3 ′ on the first surface 211 and covering the light-transmitting structure 213 .

[0206] The coating area of ​​the curing glue 3' can be referred to FIG. 5A to FIG. 8B The glue-coated area 2111 shown in the figure can cover at least a portion of the first opening 2131 by coating the curing glue 3 ′ on the glue-coated area 2111 , so that the curing glue 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 curing glue 3 ′, and the second opening 2132 is connected to the installation space 11 .

[0208] The second opening 2132 is connected to the installation space 11, so that light can enter the second opening 2132 from the installation space 11, and then pass through the light-transmitting structure 213. The light source 2000 can be located outside the installation space 11, or the light source 2000 can be located inside the installation 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 , irradiating light on one side of the second surface 212 , the light enters the light-transmitting structure 213 from the installation space 11 , irradiates the cured glue 3 ′, and the cured glue 3 ′ forms the cured glue 3 .

[0210] Among them, since the motor 1 is on one side of the second surface 212, there is no obstruction at the opening of the second surface 13, so that light can be irradiated from the opening of the second surface 13 into the installation space 11, and then incident on the light-transmitting structure 213 to irradiate and cure the curing glue 3'. It should be noted that in some embodiments, irradiating the curing glue 3' with light can pre-cure the curing glue 3', and other methods are required to subsequently completely cure the curing glue 3' into curing glue 3. In other embodiments, irradiating the curing glue 3' with light can completely cure the curing glue 3' into curing glue 3.

[0211] In this embodiment, since the first lens 2 is provided with a light-transmitting structure 213, light can be directly irradiated from the light-transmitting structure 213 to the curing glue 3' from one side of the second surface 212, which can overcome the problem that the curing glue 3' is blocked on all sides and cannot be illuminated from all sides. In this embodiment, vertical or oblique illumination can be incident on the light-transmitting glue, which improves the convenience of curing the curing glue 3' by irradiating light.

[0212] Please refer to Fig.15 , Fig.16 and Fig.17 , Fig.15 yes Fig.13 A schematic diagram of the assembly process of the second lens 4 in the assembly method of the motor assembly 10 is shown; Fig.16 yes Fig.13 A schematic diagram of the process of aligning the second lens 4 and the first lens 2 in the assembly method of the motor assembly 10; Fig.17 yes Fig.16 The schematic diagram of the structure of aligning the first lens 2 and the second lens 4 in the assembly method of the motor 1 is shown.

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

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

[0215] The second lens 4 can be installed on the object side of the first lens 2 (please refer to Figure 2A ), or the second lens 4 can also be installed on the image side of the first lens 2 (please refer to Figure 2B In this embodiment, the second lens 4 is installed on the object side of the first lens 2 for illustration.

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

[0217] The first lens 2 and the second lens 4 are installed and assembled through an active alignment (AA) process to ensure assembly accuracy. Specifically, the motor 1 and the second lens 4 can be fixed by a first fixing clamp 3000 , and the first lens 2 can be fixed by a second fixing clamp 4000 .

[0218] In some embodiments, in the AA process, auxiliary calibration may be performed by the sensor 5000 . Specifically, step S301 and step S302 may be performed after step S30 and before step S40 .

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

[0223] Among them, the sensor 5000 can use a golden sensor, and the sensor 5000 is used to provide a calibration benchmark and reference to adjust 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, thereby realizing dynamic calibration, so that the optical axis of the first lens 2 can coincide with the optical axis of the second lens 4. In addition, the sensor 5000 can also be used to calibrate other parameters to ensure the consistency of the imaging effect of the camera module 100 calibrated by the sensor 5000.

[0224] Among them, an equivalent mirror 7000 can also be arranged between the second lens 4 and the sensor 5000, and the equivalent mirror 7000 can be used to achieve 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 Figures 17 to 19 , Fig.18 yes Fig.13A schematic diagram of a process of curing the glue 3' in some embodiments in the assembly method of the motor assembly 10 shown; Fig.19 yes Fig.13 FIG. 1 is a schematic diagram of a process of irradiating light in an assembly method of the motor assembly 10 in some embodiments.

[0227] S41 , irradiating light on one side of the second surface 212 , the light enters the light-transmitting structure 213 from the installation space 11 , and irradiates the curing glue 3 ′, so that the curing glue 3 ′ is pre-cured.

[0228] Among them, after the curing glue 3' is irradiated with light, the curing glue 3' can be pre-cured. 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 removed from the fixing device in the AA process to perform other processes.

[0229] The light emitted by the light source 2000 can enter the installation space 11 from the spacing space between the second fixing clip 4000 and the motor 1 , and enter the curing glue 3 ′ from the light-transmitting structure 213 .

[0230] S42, heating the pre-cured curing glue 3' until it is completely cured to form the curing glue 3.

[0231] The pre-cured curing glue 3 ′ can be further cured by heating or the like, so that the curing glue 3 ′ can be completely cured, thereby forming the curing glue 3 and completing the assembly of the motor assembly 10 .

[0232] In some embodiments, the curing glue 3' may be an ultraviolet thermosetting glue. Step S40 may include step S411.

[0233] S411 , irradiating ultraviolet light on one side of the second surface 212 , the ultraviolet light enters the second opening 2132 from the installation space 11 , and is emitted from the first opening 2131 to the curing glue 3 ′.

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