Description

Technical Field

[0001] This application relates to the field of camera module technology, and more particularly to a method for installing a camera device. Background Technology

[0002] With the development of hardware technology for image processing and the increasing demand from users for image capture, camera devices have been installed in portable terminals (such as cellular phones and smartphones, as well as stand-alone camera devices). However, as users raise their standards for image capture, they demand technologies that can enable clear imaging of the subject and prevent image blurring caused by hand shake or movement during shooting.

[0003] Autofocus (AF) refers to the design of a camera device that measures distance to a specific area and then adjusts the lens to form a focus, so that the image in the camera device looks clear. Optical image stabilization (OIS) is a technology used to counteract image blur caused by hand shake or movement during the shooting process.

[0004] Currently, camera devices typically include a driver, a lens, and an imaging chip. During assembly, it is usually necessary to first install the focusing motor onto the base of the driver, then install the lens onto the focusing motor, and then install the imaging chip onto the base of the driver. Next, the lens and imaging chip need to be aligned. Since the lens and imaging chip are already mounted on the base of the driver, this increases the difficulty of aligning the lens and imaging chip, and this assembly method is relatively complex, resulting in low assembly efficiency.

Detailed Implementation

[0020] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0021] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0022] The following is in conjunction with the appendix Figure 1-16 This application describes a method for installing a camera device 100 according to an embodiment of the present application.

[0023] like Figure 1 As shown, the camera device 100 in this embodiment includes a first module 10, a second module 20 and a third module 30. The first module 10 includes a driving carrier 11 and a lens assembly 12. The driving carrier 11 is provided with a first space 111, a focusing coil 112 and an image stabilizing magnet 114. The lens assembly 12 is provided with a focusing magnet 123.

[0024] For example, the driving carrier 11 can be a ring structure formed by connecting multiple side walls end to end, and a first space 111 is defined between the multiple side walls. This makes it easy to use the first space 111 to store at least part of the lens assembly 12, thereby reducing the volume of the first module 10.

[0025] It is understood that the lens assembly 12 and the focusing magnet 123 of this application can be an integral structure, that is, the lens assembly 12 can be an integral lens. For example, the lens assembly 12 can include a lens 121, a lens bracket 122 and a focusing magnet 123. The lens bracket 122 can be a hollow structure, with the lens 121 disposed inside the hollow structure. The outer side of the lens bracket 122 is provided with a mounting position for setting the focusing magnet 123. In this way, when the focusing coil 112 is provided on the driving carrier 11, the focusing coil 112 can drive the focusing magnet 123 to directly drive the lens assembly 12 to move along the optical axis to achieve focusing. This eliminates the need for a separate focusing carrier in the imaging device of this application, which simplifies the installation process and improves production efficiency. At the same time, the focusing magnet 123 can be directly installed on the lens bracket 122, making the arrangement of the lens assembly 12 and the focusing magnet 123 more compact. In particular, the lens bracket 122 replaces the function of the lens barrel, which allows the lens assembly 12 of this application to eliminate the lens barrel, thereby reducing the radial dimension of the lens assembly 12 and facilitating the miniaturization design of the lens assembly 12.

[0026] like Figure 1 As shown, the second module 20 includes an imaging chip 21, which can be an image sensor. The imaging chip 21 is used to receive light from the lens assembly 12 to form an image.

[0027] It is understood that the second module 20 may also include a circuit board, which can be a flexible circuit board or a rigid circuit board, without limitation. The circuit board is electrically connected to the imaging chip 21 and is an integral structure. The circuit board may also be electrically connected to the image stabilization coil 32 and the focus coil 112. In this way, the installation of the circuit board can be completed simultaneously with the installation of the imaging chip 21, thereby simplifying the installation steps.

[0028] like Figure 1 As shown, the third module 30 includes a base 31, which has a second space 311 and a stabilization coil 32.

[0029] For example, the base 31 can be a ring structure formed by connecting multiple side walls end to end, and the inner wall of the base 31 defines a second space 311. This makes it easier to use the second space 311 to store at least part of the first module 10 and / or the second module 20, thereby reducing the volume of the camera device 100.

[0030] Furthermore, the base 31 is provided with an image stabilization coil 32. After the first module 10 and the second module 20 are installed into the third module 30, the image stabilization coil 32 is energized to drive the image stabilization magnet 114 to drive the drive carrier 11 and the lens assembly 12 to move, thereby realizing the focusing and image stabilization function.

[0031] like Figure 2As shown, the installation method of the camera device 100 of this application includes: S10: Control the drive carrier 11 and / or lens assembly 12 to move along the optical axis of the lens assembly 12 until at least part of the lens assembly 12 extends into the first preset position in the first space 111 to form the first module 10.

[0032] For example Figure 3 As shown, in the direction of the lens assembly 12 and the drive carrier 11 along the optical axis (e.g.) Figure 7 When the optical axis (Z) is distributed in the first space 111, the drive carrier 11 can be controlled to move along the optical axis of the lens assembly 12 until at least part of the lens assembly 12 extends into the first preset position within the first space 111 to form the first module 10 (e.g., Figure 4 as well as Figure 8 The first module 10 shown can be controlled to move along the optical axis of the lens assembly 12 until at least part of the lens assembly 12 extends into the first preset position in the first space 111 to form the first module 10, or the drive carrier 11 and the lens assembly 12 can be controlled to move toward each other along the optical axis until at least part of the lens assembly 12 extends into the first preset position in the first space 111 to form the first module 10.

[0033] It is understandable that the first preset position refers to the design position, which is generally the position of the lens assembly 12 when a part of the lens assembly 12 is located in the first space 111 and exactly abuts against the driving carrier 11. It can also be other design positions. It is only necessary to control the entry depth during assembly. There are no excessive restrictions here.

[0034] S20: Controls the connection between the first module 10 and the second module 20 to form the focusing module 40.

[0035] For example, as shown in 5, the direction of the first module 10 and / or the second module 20 along the optical axis of the lens assembly 12 can be controlled (e.g., Figure 9 The optical axis (Z) is moved until the first module 10 and the second module 20 are aligned, and then the first module 10 and the second module 20 are connected to form the focusing module 40 (e.g., ...). Figure 6 as well as Figure 10 The focusing module 40 shown in the figure.

[0036] During the connection of the first module 10 and the second module 20, the lens assembly 12 and the imaging chip 21 can be aligned so that the center of the imaging chip 21 falls on the axis of the lens assembly 12.

[0037] In this way, the alignment of the lens assembly 12 and the imaging chip 21 can be achieved on the outside of the base 31 of the driver (i.e., the third module 30 in this application), thereby reducing the difficulty of aligning the lens assembly 12 and the imaging chip 21.

[0038] S30: Control the focusing module 40 and / or the third module 30 to move along the optical axis of the lens assembly 12 until at least part of the focusing module 40 extends into the second preset position within the second space 311 to form the camera device 100.

[0039] For example Figure 11 As shown, when the focusing module 40 and the third module 30 are distributed along the optical axis, the focusing module 40 can be controlled to move along the optical axis of the lens assembly 12 until at least a portion of the focusing module 40 extends into the second preset position within the second space 311 to form the imaging device 100 (e.g., ...). Figure 12 The camera device 100 shown may control the third module 30 to move along the optical axis of the lens assembly 12 until at least part of the focusing module 40 extends into the second preset position in the second space 311, or control the focusing module 40 and the third module 30 to move toward each other along the optical axis until at least part of the focusing module 40 extends into the second preset position in the second space 311.

[0040] It is understandable that the second preset position refers to the design position, which is generally the position of the lens assembly 12 when part of the focusing module 40 is located in the second space 311 and exactly abuts against the base 31. It can also be other design positions, as long as the entry depth during assembly is controlled, there are no excessive restrictions here.

[0041] According to the installation method of the camera device 100 in the embodiments of this application, the driving carrier 11 of the camera device 100 is provided with a focusing coil 112 and an image stabilization magnet 114, so that the driving carrier 11 can be used to realize both focusing and image stabilization functions. During installation, the lens assembly 12 can be installed on the driving carrier 11 to form a first module 10, and then the first module 10 is connected to the second module 20 to form a focusing module 40. At this time, the lens assembly 12 and the imaging chip 21 can be aligned on the outside of the driver, thereby reducing the difficulty of aligning the lens assembly 12 and the imaging chip 21. Then, the focusing module 40 and / or the third module 30 can move along the optical axis of the lens assembly 12 to realize the assembly of the camera device 100, thereby simplifying the assembly process of the camera device and improving the assembly efficiency of the camera device.

[0042] In some embodiments, the drive carrier 11 is further provided with a guide member 113, such as Figure 13As shown, “S10: Controlling the drive carrier 11 and / or lens assembly 12 to move along the optical axis of the lens assembly 12 until at least a portion of the lens assembly 12 extends into a first preset position within the first space 111 to form the first module 10” includes: S11: Control the drive carrier 11 and / or lens assembly 12 to move along the optical axis until the lens assembly 12 is guided and engaged with the guide member 113; S12: Control the drive carrier 11 and / or lens assembly 12 to continue moving along the optical axis until at least part of the lens assembly 12 extends into the first preset position in the first space 111 to form the first module 10.

[0043] Thus, the guide 113 facilitates the guidance of the drive carrier 11 and / or lens assembly 12 during the assembly process, i.e., guiding before installation, thereby improving the assembly efficiency of the camera device.

[0044] For example, the guide member 113 can be a guide rod or a ball, etc., and the lens assembly 12 can be provided with a guide groove 1222 that slides with the guide rod or ball. Alternatively, the guide member 113 can be a guide groove 1222, and the lens assembly 12 can be provided with a guide rod or a ball that slides with the guide rod. No limitation is made here.

[0045] In some embodiments, the first module 10 further includes an upper cover 13, such as Figure 14 As shown, “S10: Control the drive carrier 11 and / or lens assembly 12 to move along the optical axis of the lens assembly 12 until at least a portion of the lens assembly 12 extends into a first preset position within the first space 111 to form the first module 10” further includes: S13: When the lens assembly 12 is in the first preset position, the control cover 13 moves along the optical axis to one end of the drive carrier 11 in the optical axis direction.

[0046] S14: Securely connect the top cover 13 and the drive carrier 11 to prevent the lens assembly 12 from separating from the drive carrier 11.

[0047] For example, the upper cover 13 can be a ring-shaped part, and the upper cover 13 can be sleeved on the lens assembly 12. In this way, after the lens assembly 12 is in the first preset position and pre-fixed with the driving carrier 11, the upper cover 13 can be controlled to move along the optical axis until it is connected to the driving carrier 11. Thus, the upper cover 13 restricts the separation of the lens assembly 12 from the driving carrier 11, thereby improving the connection stability between the lens assembly 12 and the driving carrier 11.

[0048] In some embodiments, such as Figure 15 As shown, "S20: Controlling the connection between the first module 10 and the second module 20 to form the focusing module 40" includes: S21: Control the movement of the first module 10 and / or the second module 20 so that the center of the imaging chip 21 falls on the axis of the lens assembly 12.

[0049] S22: Connect the first module 10 and the second module 20 to form the focusing module 40.

[0050] It is understandable that by adjusting the relative positions of the first module 10 and the second module 20, the center of the imaging chip 21 can be made to fall on the axis of the lens assembly 12, thereby ensuring the concentricity and perpendicularity of the optical axis and thus improving the imaging quality.

[0051] In some embodiments, "S22: Connecting the first module 10 and the second module 20 to form a focusing module 40" includes: The first module 10 and the second module 20 are bonded together to form the focusing module 40. That is, after adjusting the center of the imaging chip 21 to fall on the axis of the lens assembly 12, the first module 10 and the second module 20 can be bonded together to achieve a fixed connection. Furthermore, the bonding method is relatively simple, reducing the difficulty of connection. Specifically, the adhesive material can be UV glue or a combination of UV glue and thermosetting adhesive.

[0052] In some embodiments, the third module 30 further includes a universal joint 33, and the base 31 is provided with a first bearing 51, such as Figure 16 As shown, “S30: Control the focus motor module and / or the third module 30 to move along the optical axis of the lens assembly 12 until at least part of the image stabilization magnet 114 is opposite to the image stabilization coil 32 to form the imaging device 100” includes: S31: Control the focus motor module and / or the third module 30 to move along the optical axis of the lens assembly 12 until at least part of the focus motor module extends into the second preset position in the second space 311; S32: Controls the universal joint 33 to be rotatably connected to the first bearing 51 around the first axis, the first axis being perpendicular to the optical axis.

[0053] In this way, the image stabilization coil 32 can be energized to drive the image stabilization magnet 114 to rotate the drive carrier 11 and the lens assembly 12 around the first axis, thereby realizing the image stabilization function of the camera device 100. Since the lens assembly 12 and the imaging chip 21 are fixed on the drive carrier 11 after centering, thus forming the focusing module 40, when the image stabilization function is realized, the lens assembly 12 and the imaging chip 21 can rotate with the drive carrier 11 at the same time, so that the relative position of the center of the imaging chip 21 and the axis of the lens assembly 12 does not change, thereby improving the image stabilization effect.

[0054] In some embodiments, the drive carrier 11 is provided with a second bearing 52, such as Figure 16 As shown, “S30: Control the focus motor module and / or the third module 30 to move along the optical axis of the lens assembly 12 until at least part of the focus motor module extends into the second preset position within the second space 311 to form the imaging device 100” also includes: S33: Controls the universal joint 33 to be rotatably connected to the second bearing 52 around the second axis, the second axis being perpendicular to the optical axis and perpendicular to the first axis.

[0055] In this way, the image stabilization coil 32 can be energized to drive the image stabilization magnet 114 to rotate the drive carrier 11 and the lens assembly 12 around the second axis, thereby realizing the image stabilization function of the camera device 100. Since the lens assembly 12 and the imaging chip 21 are fixed on the drive carrier 11 after centering, thus forming the focusing module 40, when the image stabilization function is realized, the lens assembly 12 and the imaging chip 21 can rotate with the drive carrier 11 at the same time, so that the relative position of the center of the imaging chip 21 and the axis of the lens assembly 12 does not change, thereby improving the image stabilization effect.

[0056] In some embodiments, when the focusing module 40 is in a second preset position, at least a portion of the driving carrier 11 is located within the second space 311.

[0057] It is understandable that when the focusing module 40 is in the second preset position, at least a part of the focusing module 40 is located in the second space 311. In order to facilitate the adjustment of the position of the imaging chip 21 in the later stage, a part of the driving carrier 11 can be set to be located in the second space 311. This facilitates the adjustment of the position of the imaging chip 21 in the later stage. At the same time, since at least a part of the lens assembly 12 is located in the first space 111 of the driving carrier 11, the driving carrier 11 and the base 31 can be sequentially fitted on the outside of the lens assembly 12, thereby making the structure of the camera device 100 more compact, which is conducive to realizing the miniaturization design of the camera device 100.

[0058] In some embodiments, the lens assembly 12 includes a lens 121 and a lens bracket 122. The lens bracket 122 is a hollow structure, and the lens 121 is disposed inside the hollow structure. The outer side of the lens bracket 122 is provided with a mounting position for setting a focusing magnet 123.

[0059] It is understood that the lens assembly 12 of this application is an integrated lens, with the lens 121 embedded in the lens bracket 122 and the outer side of the lens bracket 122 having a mounting position for setting the focusing magnet 123. Thus, when the driving carrier 11 is provided with a focusing coil 112, the focusing coil 112 can be energized to drive the focusing magnet 123 to directly drive the lens assembly 12 to move along the optical axis, thereby achieving focusing. This eliminates the need for a separate focusing carrier in the imaging device of this application, simplifying the installation process and improving production efficiency. At the same time, the focusing magnet 123 can be directly mounted to the lens bracket 122, making the arrangement of the lens assembly 12 and the focusing magnet 123 more compact. In particular, the lens bracket 122 replaces the function of the lens barrel, allowing the lens assembly 12 of this application to eliminate the lens barrel, thereby reducing the radial dimension of the lens assembly 12 and facilitating the miniaturization design of the lens assembly 12.

[0060] In some implementations, the mounting location can be a groove or a flat area for attaching magnets; this is not a limitation.

[0061] In some embodiments, the outer side of the lens bracket 122 is provided with a guide groove 1222 for slidingly engaging with the guide member 113, and the guide groove 1222 and the mounting position are spaced apart in the circumferential direction of the lens bracket 122.

[0062] In this way, the guide groove 1222 can be guided and matched with the guide member 113 set on the drive carrier 11, thereby reducing the difficulty of guiding and matching the lens assembly 12 and the drive carrier 11. Moreover, the guide groove 1222 has a simple structure, which helps to reduce the installation cost. At the same time, the guide groove 1222 and the mounting position are spaced apart in the circumferential direction of the lens bracket 122, which can avoid interference between the guide member 113 and the focusing magnet 123.

[0063] In some embodiments, the drive carrier 11 includes a plurality of sidewalls connected end to end, and two anti-shake magnets 114 are provided, which can be disposed on two adjacent sidewalls.

[0064] For example, the drive carrier 11 is constructed as a rectangular component, meaning it includes four sidewalls connected end-to-end. Two anti-shake magnets 114 are disposed on two adjacent or mutually perpendicular sidewalls. Correspondingly, two anti-shake coils 32 are also disposed on the base 31, with each anti-shake coil 32 corresponding to one of the two anti-shake magnets 114. Of course, in other embodiments, the drive carrier 11 is constructed as a polygonal component, such as a hexagonal component, in which case the two anti-shake magnets 114 are disposed on two adjacent sidewalls; or the drive carrier 11 is constructed as an octagonal component, in which case the two anti-shake magnets 114 are disposed on two mutually perpendicular sidewalls.

[0065] One anti-shake coil 32 is used to drive the corresponding anti-shake magnet 114 to move the drive carrier 11 around an anti-shake axis to achieve anti-shake function in one direction. The other anti-shake coil 32 is used to drive the corresponding anti-shake magnet 114 to move the drive carrier 11 around another anti-shake axis to achieve anti-shake function in another direction. The two directions are different.

[0066] This allows the camera device 100 of this application to achieve image stabilization in at least two directions, thereby facilitating the improvement of the image stabilization capability of the camera device 100.

[0067] In some embodiments, the focusing coil 112 is disposed on a side wall adjacent to or opposite to either of the two image stabilizing magnets 114.

[0068] For example, in the implementation where the drive carrier 11 is constructed as a rectangular component, two image stabilizing magnets 114 are disposed on two adjacent side walls, and the focusing coil 112 is disposed on the side wall where no image stabilizing magnet 114 is disposed. The focusing coil 112 and one image stabilizing magnet 114 are disposed on adjacent side walls, and the focusing coil 112 and one image stabilizing magnet 114 are disposed opposite to each other.

[0069] This allows the focusing coil 112 to be mounted on the side wall of the drive carrier 11 where the image stabilizing magnet 114 is not located, thus avoiding interference between the focusing coil 112 and the image stabilizing magnet 114. Furthermore, the focusing coil 112 can make full use of the side wall of the drive carrier 11 where the image stabilizing magnet 114 is not located, making the arrangement of the focusing coil 112, the drive carrier 11, and the image stabilizing magnet 114 more compact, reducing wasted space, and thus achieving a miniaturized design of the camera device 100.

[0070] In some embodiments, the drive carrier 11 is sleeved on the outside of the lens assembly 12 to form an overall layout of internal focusing and external image stabilization. This makes the arrangement of the drive carrier 11 and the lens assembly 12 more compact, which helps to reduce the waste of installation space, thereby realizing the miniaturization design of the camera device 100, and also enables the camera device 100 to simultaneously realize the design of the image stabilization function and the focusing function.

[0071] In some embodiments, the lens holder 122 is provided with a mounting space for accommodating at least a portion of the lens 121, and a focusing magnet 123 is disposed on the outer peripheral wall of the lens holder 122. This allows the lens 121 to be mounted within the mounting space of the lens holder 122, thereby making the arrangement of the lens holder 122 and the lens 121 more compact.

[0072] In some embodiments, the lens holder 122 is provided with a first mounting groove, and at least a portion of the focusing magnet 123 is housed in the first mounting groove.

[0073] It is understandable that by setting the first mounting slot, the focusing magnet 123 can be accommodated in the first mounting slot, thereby improving the connection stability between the focusing magnet 123 and the lens bracket 122. In addition, the setting of the first mounting slot can also reduce the volume of the lens bracket 122, so as to realize the miniaturization and lightweight design of the lens bracket 122. At the same time, the setting method of the first mounting slot is relatively simple, which helps to reduce the difficulty of setting.

[0074] In the implementation where the driving carrier 11 is mounted on the lens assembly 12, the first mounting slot can be opened towards the driving carrier 11 so that the focusing magnet 123 can directly face the focusing coil 112 to achieve magnetic force cooperation.

[0075] In some embodiments, the drive carrier 11 is provided with a second mounting groove, in which at least a portion of the focusing coil 112 is housed, and the second mounting groove is disposed opposite to the first mounting groove.

[0076] It is understandable that by setting a second mounting slot, the focusing coil 112 can be accommodated in the second mounting slot, thereby improving the connection stability between the focusing coil 112 and the drive carrier 11. In addition, the setting of the second mounting slot can also reduce the volume of the drive carrier 11 after it is combined with the focusing coil 112, so as to realize the miniaturization and lightweight design of the drive carrier 11. At the same time, the setting method of the second mounting slot is relatively simple, which helps to reduce the difficulty of setting.
