Description

Technical Field

[0001] This application relates to the field of camera module technology, and more particularly to a method for installing a driver. 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 focusing motor, and a lens. During assembly, the focusing motor is usually installed onto the driver first, and then the lens is installed onto the focusing motor. Because the driver needs to be fitted with the focusing motor, the driver is relatively large, and the assembly method of the camera device is relatively complex, resulting in low assembly efficiency. Summary of the Invention

[0005] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a method for installing a driver, which facilitates the miniaturization of the driver design.

[0007] According to the driver installation method of the present application embodiment, the base and the first carrier can move in the optical axis direction of the lens to achieve assembly of the two, and the second carrier and the first carrier can also move in the optical axis direction of the lens to achieve assembly. Since the first carrier is provided with an image stabilization magnet and a focusing coil, and the second carrier is provided with a focusing magnet, the focusing coil and the focusing magnet can be integrated with the driver, thereby facilitating the miniaturization design of the driver.

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 1-12 This application describes a method for installing a driver according to an embodiment.

[0023] like Figure 1 and Figure 2 As shown, the driver 100 includes a base 1, a first carrier 2, and a second carrier 3. The base 1 is provided with a first opening 11 and an image stabilization coil 12. The first carrier 2 is provided with a second opening 21, an image stabilization magnet 22, and a focusing coil 23. The second carrier 3 is used to mount the lens 200 and is provided with a focusing magnet 31.

[0024] When the lens 200 is mounted on the second carrier 3, the focusing coil 23 can drive the focusing magnet 31 to move the second carrier 3 and the lens 200 simultaneously in the direction of the optical axis of the lens 200 to achieve the focusing function. The image stabilization coil 12 can drive the image stabilization magnet 22 to move the first carrier 2, the second carrier 3 and the lens 200 simultaneously to achieve the image stabilization function.

[0025] Since the first carrier 2 is equipped with an image stabilization magnet 22 and a focusing coil 23, and the second carrier 3 is equipped with a focusing magnet 31, the focusing coil 23 and the focusing magnet 31 can be integrated with the driver 100, thereby facilitating the miniaturization design of the driver 100.

[0026] like Figure 3 As shown, the installation method of the drive includes: S10: Control the base 1 and / or the first carrier 2 to move along the optical axis of the lens 200 until the first carrier 2 extends from the first opening 11 into the first preset position inside the base 1 to form the pre-assembled component 10.

[0027] For example Figure 4 As shown, when the base 1 and the first carrier 2 are distributed along the optical axis, the base 1 can be controlled to move along the optical axis until the first carrier 2 extends from the first opening 11 into the first preset position inside the base 1 to form the pre-assembled assembly 10 (e.g., ...). Figure 5 The pre-installed component 10 shown, or the first carrier 2 is controlled to move along the optical axis until the first carrier 2 extends from the first opening 11 into the first preset position in the base 1 to form the pre-installed component 10, or the base 1 and the first carrier 2 are controlled to move close to each other along the optical axis until the first carrier 2 extends from the first opening 11 into the first preset position in the base 1 to form the pre-installed component 10.

[0028] It is understandable that the first preset position refers to the design position, which is generally the position of the first carrier 2 when a part of the first carrier 2 is located inside the base 1 and exactly abuts against the base 1. It can also be other design positions. It is only necessary to control the entry depth during assembly. There are no excessive restrictions here.

[0029] S20: Control the second carrier 3 and / or the pre-mounted component 10 to move along the optical axis of the lens 200 until the second carrier 3 extends from the second opening 21 into the second preset position inside the first carrier 2 to form the driver 100.

[0030] For example Figure 6 As shown, when the second carrier 3 and the pre-installed assembly 10 are distributed along the optical axis, the second carrier 3 can be controlled to move along the optical axis until the second carrier 3 extends from the second opening 21 into the second preset position within the first carrier 2 to form the driver 100 (e.g., Figure 7 The driver 100 shown in the figure, or the pre-mounted component 10 is controlled to move along the optical axis until the second carrier 3 extends from the second opening 21 into the second preset position in the first carrier 2 to form the driver 100, or the second carrier 3 and the pre-mounted component 10 are controlled to move close to each other along the optical axis until the second carrier 3 extends from the second opening 21 into the second preset position in the first carrier 2 to form the driver 100.

[0031] It is understandable that the second preset position refers to the design position, which is generally the position of the second carrier 3 when a part of the second carrier 3 is located inside the first carrier 2 and exactly abuts against the first carrier 2. It can also be other design positions. It is only necessary to control the entry depth during assembly. There are no excessive restrictions here.

[0032] In this way, the installation step of the focusing motor can be omitted when assembling the camera device, which simplifies the assembly process and improves the assembly efficiency of the camera device.

[0033] In some embodiments, such as Figure 1 As shown, the first carrier 2 is provided with a guide 24, such as Figure 8 As shown, “S20: Controlling the second carrier 3 and / or pre-mounted assembly 10 to move along the optical axis of the lens 200 until the second carrier 3 extends from the second opening 21 into the second preset position within the first carrier 2 to form the driver 100” includes: S21: Control the second carrier 3 and / or the pre-mounted assembly 10 to move along the optical axis of the lens 200 until the second carrier 3 is guided and engaged with the guide member 24; S22: Control the second carrier 3 and / or pre-mounted component 10 to continue moving along the optical axis of the lens 200 until the second carrier 3 extends from the second opening 21 into the second preset position inside the first carrier 2.

[0034] For example, the second carrier 3 can be controlled to move along the optical axis of the lens 200 until the second carrier 3 is guided and engaged with the guide member 24; or the pre-mounted assembly 10 can be controlled to move along the optical axis of the lens 200 until the second carrier 3 is guided and engaged with the guide member 24; or the pre-mounted assembly 10 and the second carrier 3 can be controlled to move relative to each other along the optical axis of the lens 200 until the second carrier 3 is guided and engaged with the guide member 24.

[0035] In this way, the guide 24 facilitates the guidance of the first carrier 2 or the second carrier 3 during the assembly process, that is, guiding before installation, thereby improving the assembly efficiency of the driver 100.

[0036] In some embodiments, the guide member 24 includes a guide rod, and the second carrier 3 is provided with a guide groove. "S21: Controlling the second carrier 3 and / or the pre-mounted assembly 10 to move along the optical axis of the lens 200 until the second carrier 3 is guided and engaged with the guide member 24" includes: Control the second carrier 3 and / or pre-mounted assembly 10 to move along the optical axis of the lens 200 until the guide rod engages with the guide groove.

[0037] In this way, the sliding cooperation between the guide rod and the guide groove can guide the assembly of the pre-assembled component 10 and the second carrier 3. Moreover, the structure of the guide rod and the guide groove is relatively simple, which helps to reduce the difficulty of setting up.

[0038] In some embodiments, the guide rod is a cylindrical rod and the guide groove is a "V" shaped groove. This reduces the risk of rotation of the guide rod within the guide groove, thereby reducing the relative rotation risk of the first carrier 2 and the second carrier 3, and thus improving the stability of the guide fit.

[0039] In some embodiments, the first carrier 2 is provided with a magnetic element 25, such as... Figure 9 As shown, "S21: Controlling the second carrier 3 and / or pre-mounted assembly 10 to move along the optical axis of the lens 200 until the second carrier 3 is guided and engaged with the guide member 24" includes: S211: Control the second carrier 3 and / or the pre-mounted component 10 to move along the optical axis of the lens 200 until the focusing magnet 31 and the magnetic component 25 reach the pre-fitting position. S212: After the second carrier 3 and / or pre-mounted component 10 moves to the pre-fitting position, control the second carrier 3 and / or pre-mounted component 10 to continue moving along the optical axis of the lens 200 until the second carrier 3 is guided and fitted with the guide member 24.

[0040] It is understandable that the pre-fitting position is generally when the magnetic component 25 on the first carrier 2 is located within the magnetic field range of the focusing magnet 31 on the second carrier 3, and the focusing magnet 31 and the magnetic component 25 just sense the position of the second carrier 3 when they are magnetically attracted to each other.

[0041] Thus, during the installation of the second carrier 3, even if the relative positions of the pre-installed component 10 and the second carrier 3 are misaligned, adjustment can be made through the magnetic attraction between the magnetic component and the focusing magnet 31. This ensures that the side of the second carrier 3 with the focusing magnet 31 is accurately aligned with the side of the first carrier 2 with the magnetic component 25, preventing the second carrier 3 from being installed in the wrong direction. In other words, the magnetic component 25 can play a foolproof or positioning role in the installation of the second carrier 3. This allows for magnetic attraction before guidance, thereby improving the accuracy of the guiding fit.

[0042] In some embodiments, the driver 100 further includes a top cover 4, such as Figure 10 As shown, the driver installation method also includes: S30: When the second carrier 3 is in the second preset position, control the upper cover 4 to move along the optical axis of the lens 200 to one end of the pre-installed component 10 in the optical axis of the lens 200; S40: Securely connect the top cover 4 to the pre-installed component 10 to prevent the second carrier 3 from separating from the pre-installed component 10.

[0043] It is understood that when the second carrier 3 is in the second preset position, the upper cover 4 can be controlled to move in the optical axis direction of the lens 200 until it is connected to the pre-mounted component 10. The upper cover 4 is used to abut against one side of the second carrier 3 in the optical axis direction of the lens 200, thereby limiting the range of movement of the second carrier 3 in the optical axis direction and preventing the second carrier 3 from separating from the pre-mounted component 10.

[0044] In some embodiments, the driver 100 further includes a universal joint 5, the second carrier 3 is provided with a first bearing 51, and the base 1 is provided with a second bearing 52, such as Figure 11 As shown, the installation method for the drive also includes: S50: Control the universal joint 5 to move along the optical axis of the lens 200 until the universal joint 5 is rotatably connected to the first bearing 51 around the first axis, which is perpendicular to the optical axis of the lens 200. S60: The universal joint 5 is rotatably connected to the second bearing 52 around the second axis, which is perpendicular to the optical axis of the lens 200 and perpendicular to the first axis.

[0045] In this way, the image stabilization coil 12 can be energized to drive the image stabilization magnet 22 to rotate the first carrier 2 and the second carrier 3 relative to the universal joint 5 around the first axis, thereby achieving the image stabilization function of the lens 200 in the circumferential direction of the first axis. Alternatively, the image stabilization coil 12 can be energized to drive the image stabilization magnet 22 to rotate the first carrier 2 and the second carrier 3 relative to the base 1 around the second axis, thereby achieving the image stabilization function of the lens 200 in the circumferential direction of the second axis. Since the first axis and the second axis are perpendicular, the driver 100 can achieve the image stabilization function of the lens 200 in at least two directions, thereby improving the image stabilization effect.

[0046] In some embodiments, the driver 100 further includes a photosensitive component 7, and the second carrier 3 is provided with a light-passing hole for obstructing the light path, such as... Figure 12 As shown, the installation method for the drive also includes: S70: Control the photosensitive element 7 to move until the photosensitive element 7 is opposite to the light-transmitting hole; S80: Fixed connection between photosensitive component 7 and driver 100.

[0047] Understandably, the second carrier 3 is used to mount the lens 200, and the light-passing hole can be set opposite to the lens 200 to ensure that the light path of the lens 200 is unobstructed. The photosensitive component 7 may include, but is not limited to, an imaging chip or an image sensor. The photosensitive component 7 is opposite to the light-passing hole, and then the photosensitive component 7 is fixedly connected to the driver 100 to ensure the connection stability between the photosensitive component 7 and the driver 100, and to ensure that the light entering from the lens 200 can stably enter the photosensitive component 7, so that the photosensitive component 7 receives the light from the lens 200 for imaging.

[0048] In some embodiments, "controlling the photosensitive component 7 to move until the photosensitive component 7 is opposite to the light-transmitting hole" includes: The relative movement of the photosensitive component 7 and the driver 100 is controlled so that the center of the photosensitive component 7 falls on the center line of the light-transmitting hole.

[0049] It is understandable that by adjusting the relative positions of the photosensitive component 7 and the driver 100, the center of the photosensitive component 7 can be made to fall on the axis of the light-transmitting aperture, thereby ensuring the concentricity and perpendicularity of the optical axis and thus improving the imaging quality.

[0050] In this way, when the image stabilization coil 12 is energized, it can drive the image stabilization magnet 22 to move the first carrier 2, the second carrier 3, the lens 200, and the photosensitive component 7 simultaneously to achieve the image stabilization function. At the same time, during the image stabilization process, because the lens 200 and the photosensitive component 7 move synchronously, the center of the photosensitive component 7 always falls on the axis of the light-transmitting aperture, thereby ensuring the concentricity and perpendicularity of the optical axis and thus improving the image quality.

[0051] In some embodiments, the second carrier 3 is a hollow structure, and the outer side of the second carrier 3 is provided with a mounting position for setting the focusing magnet 31.

[0052] It is understandable that the second carrier 3 is set as a hollow structure so that the lens 200 can be embedded in the hollow structure, and the outer side of the second carrier 3 is provided with a mounting position for setting the focusing magnet 31. In this way, when the first carrier 2 is provided with a focusing coil 23, the focusing coil 23 can be energized to drive the focusing magnet 31 to drive the second carrier 3 to move the lens along the optical axis, thereby achieving focusing.

[0053] Therefore, the driver 100 of this application does not need to be equipped with a separate focusing motor, which simplifies its installation steps and improves production efficiency. At the same time, the focusing magnet 31 can be directly installed on the second carrier 3, making the arrangement of the second carrier 3 and the focusing magnet 31 more compact. In some implementations, the second carrier 3 can replace the function of the lens barrel, that is, the second carrier 3 can be integrated with the lens 200. In this way, the lens 200 of this application can eliminate the lens barrel, thereby reducing the radial dimension of the lens 200 and facilitating the miniaturization design of the lens 200.

[0054] In some implementations, the mounting location can be a groove or a flat area for attaching magnets; this is not a limitation.

[0055] In some embodiments, the outer side of the second carrier 3 is provided with a guide groove for slidingly engaging with the guide member 24, and the guide groove is offset from the mounting position in the circumferential direction of the second carrier 3.

[0056] In this way, the guide groove and the guide member 24 set on the first carrier 2 can be guided and matched, thereby reducing the difficulty of guiding and matching the first carrier 2 and the second carrier 3. Moreover, the guide groove has a simple structure, which helps to reduce the installation cost. At the same time, the guide groove and the mounting position are spaced apart in the circumferential direction of the lens 200 bracket, which can avoid interference between the guide member 24 and the focusing magnet 31.

[0057] In some embodiments, the first carrier 2 includes a plurality of sidewalls connected end to end, and two anti-shake magnets 22 are provided, which can be disposed on two adjacent sidewalls.

[0058] For example, the first carrier 2 is constructed as a rectangular component, meaning it includes four sidewalls connected end-to-end. Two anti-shake magnets 22 are disposed on two adjacent or mutually perpendicular sidewalls. Correspondingly, the base 1 also has two anti-shake coils 12, with each anti-shake coil 12 corresponding to one of the two anti-shake magnets 22. Of course, in other embodiments, the first carrier 2 is constructed as a polygonal component, such as a hexagonal component, in which case the two anti-shake magnets 22 are disposed on two adjacent sidewalls; or the first carrier 2 is constructed as an octagonal component, in which case the two anti-shake magnets 22 are disposed on two mutually perpendicular sidewalls.

[0059] One of the anti-shake coils 12 is used to drive the corresponding anti-shake magnet 22 to move the first carrier 2 around an anti-shake axis to achieve anti-shake function in one direction, and the other anti-shake coil 12 is used to drive the corresponding anti-shake magnet 22 to move the first carrier 2 around another anti-shake axis to achieve anti-shake function in another direction. The two directions are different.

[0060] This allows the driver 100 of this application to achieve anti-shake function in at least two directions, thereby facilitating the improvement of the anti-shake capability of the driver 100.

[0061] In some embodiments, the focusing coil 23 is disposed on a side wall adjacent to or opposite to either of the two image stabilizing magnets 22.

[0062] For example, in the implementation where the first carrier 2 is constructed as a rectangular component, two image stabilizing magnets 22 are disposed on two adjacent side walls, and the focusing coil 23 is disposed on the side wall where no image stabilizing magnet 22 is disposed. The focusing coil 23 and one image stabilizing magnet 22 are disposed on adjacent side walls, and the focusing coil 23 and one image stabilizing magnet 22 are disposed opposite to each other.

[0063] This allows the focusing coil 23 to be mounted on the side wall of the first carrier 2 where the image stabilizing magnet 22 is not located, thereby avoiding interference between the focusing coil 23 and the image stabilizing magnet 22. Furthermore, the focusing coil 23 can make full use of the side wall of the first carrier 2 where the image stabilizing magnet 22 is not located, making the arrangement of the focusing coil 23, the first carrier 2, and the image stabilizing magnet 22 more compact, reducing wasted space, and thus achieving a miniaturized design of the driver 100.

[0064] In some embodiments, the first carrier 2 is sleeved on the outside of the second carrier 3 to form an overall layout of internal focusing and external image stabilization. This makes the arrangement of the first carrier 2 and the second carrier 3 more compact, which helps to reduce the waste of installation space, thereby realizing the miniaturization design of the driver 100, and also enables the driver 100 to simultaneously realize the design of the image stabilization function and the focusing function.

[0065] In some embodiments, the second carrier 3 is provided with a mounting space for accommodating at least a portion of the lens 200, and a focusing magnet 31 is disposed on the outer peripheral wall of the second carrier 3. This allows the lens 200 to be mounted within the mounting space of the second carrier 3, thereby making the arrangement of the second carrier 3 and the lens 200 more compact.

[0066] In some embodiments, the second carrier 3 is provided with a first mounting groove, and at least a portion of the focusing magnet 31 is housed in the first mounting groove.

[0067] It is understandable that by setting the first mounting slot, the focusing magnet 31 can be housed in the first mounting slot, thereby improving the connection stability between the focusing magnet 31 and the second carrier 3. In addition, the setting of the first mounting slot can also reduce the volume of the second carrier 3, so as to realize the miniaturization and lightweight design of the second carrier 3. At the same time, the setting method of the first mounting slot is relatively simple, which helps to reduce the difficulty of setting.

[0068] In the implementation where the first carrier 2 is mounted on the second carrier 3, the first mounting groove can be opened towards the first carrier 2 so that the focusing magnet 31 can directly face the focusing coil 23 to achieve magnetic force cooperation.

[0069] In some embodiments, the first carrier 2 is provided with a second mounting groove, and at least a portion of the focusing coil 23 is housed in the second mounting groove, which is disposed opposite to the first mounting groove.

[0070] It is understandable that by setting a second mounting slot, the focusing coil 23 can be housed in the second mounting slot, thereby improving the connection stability between the focusing coil 23 and the first carrier 2. In addition, the setting of the second mounting slot can also reduce the volume of the first carrier 2 after it is combined with the focusing coil 23, so as to realize the miniaturization and lightweight design of the first carrier 2. At the same time, the setting method of the second mounting slot is relatively simple, which helps to reduce the difficulty of setting.
