Description

An assembly method for a suspended wire OIS motor and the suspended wire OIS motor itself. Technical Field

[0001] This disclosure relates to the field of OIS motors, and particularly to an assembly method for a suspended wire OIS motor and the suspended wire OIS motor. Background Technology

[0002] Optical image stabilization motor, also known as OIS (Optical Image Stabilization) motor, can not only achieve focusing drive in the vertical (Z-axis) direction, but also move in any direction on the horizontal plane in the forward, backward, left, and right directions (X-axis and Y-axis) direction. In order to compensate for external interference signals in time, the image during shooting is relatively still and the picture is clear.

[0003] OIS motors are mainly implemented through various methods such as suspension wire type, ball bearing type, and shape memory metal type. The suspension wire type OIS motor consists of a suspension system composed of four suspension wires of equal length. By driving the movable components to move on the plane relative to the image sensor, the anti-shake effect is achieved.

[0004] Currently, in the assembly of suspension-type OIS motors, the relative positions of the movable components (such as brackets and carriers) and stator components (such as bases) can only be ensured by tooling and fixtures. This requires meeting not only the spatial (Z-axis) requirements on the drawings but also the distance dimensional requirements in the XY plane. Due to the cumulative tolerances of parts and tooling during tooling positioning, the suspension holes in the base and movable components become misaligned (i.e., severely eccentric). This makes it difficult for the suspension wire to pass through both the base and movable component suspension holes in one go during wire threading, increasing the assembly process difficulty. Furthermore, when the suspension holes at both ends of the wire are severely eccentric, the wire threading process can easily cause deformation of the elastic connecting parts of the movable component, thus affecting motor performance.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0052] According to a first aspect of this disclosure, referring to Figures 1 to 4, an assembly method for a suspended wire OIS motor is provided. This assembly method for the suspended wire OIS motor can provide precise positioning for the assembly of the suspended wire, which not only helps to improve the installation efficiency of the suspended wire, but also better ensures the performance of the suspended wire OIS motor.

[0053] Specifically, the suspended wire OIS motor includes a stator assembly, a movable assembly, and a feed belt 13;

[0054] The stator assembly includes a base 11, and the base 11 has a first suspension wire hole 71 on the side facing the movable assembly; the base 11 is provided with a positioning post 12, and the positioning post 12 is close to the first suspension wire hole 71.

[0055] The movable component includes a suspension wire 7, a first elastic connector 3, and a second elastic connector 8; the first elastic connector 3 is provided with a second suspension wire hole 72; the first elastic connector 3 is provided on the side of the movable component away from the base 11, and the second elastic connector 8 is provided on the side of the movable component closer to the base 11; the material strip 13 is connected to the second elastic connector 8, and the material strip 13 is provided with a positioning hole 132;

[0056] More specifically, the assembly method of this suspension-type OIS motor includes the following steps:

[0057] Step S1: The positioning hole 132 of the material strip is fitted onto the positioning post 12 of the base so that the first suspension wire hole 71 and the second suspension wire hole 72 are concentrically arranged.

[0058] Step S2: Fix the first end of the suspension wire 7 to the first suspension wire hole 71, and fix the second end of the suspension wire 7 to the second suspension wire hole 72.

[0059] Step S3: Cut the strip 13, and the second elastic connector 8 is disconnected from the positioning post 12.

[0060] Step S4: Remove the material strip 13 fitted on the positioning post 12.

[0061] In this embodiment, the component (i.e., the material strip) between the base 11 and the first elastic connector 3 is positioned so that the first suspension wire hole 71 on the base 11 is concentric with the second suspension wire hole 72 of the first elastic connector 3, thereby making the wire threading 7 simple, allowing it to pass through in one straight up and down motion, significantly improving the efficiency of wire threading 7.

[0062] In addition, the assembly method of the suspended wire OIS motor of this application can solve the problem of misalignment between the suspended wire 7 hole of the base 11 and the suspended wire 7 hole of the movable component caused by positioning by tooling fixture, and can solve the problem of not being able to pass the suspended wire 7 through, thereby improving the wire passing yield and solving the problem of poor motor performance caused by wire passing problems.

[0063] Optionally, referring to Figure 10, the material strip 13 is provided with a cutting area 131;

[0064] When the first end of the suspension wire 7 is fixed to the first suspension wire hole 71 and the second end is fixed to the second suspension wire hole 72, the cutting area 131 is disconnected, and the second elastic connector 8 is disconnected from the positioning post 12.

[0065] In the above embodiment, by disconnecting the cutting area 131, the functionality of the second elastic connector 8 can be guaranteed without affecting the performance of the suspension wire OIS motor, and the operation is simple.

[0066] It should be noted that, referring to Figure 5, after the movable component and the stator component are assembled, a gap 14 is formed between the bracket 2 and the base 11 to meet the movement requirements of the movable component in a direction parallel to the optical axis.

[0067] Optionally, the number of positioning posts 12 is 2 to 4; the base 11 facing the movable component is a square with four corners;

[0068] The two positioning posts 12 are located at opposite corners of the base 11, which allows fewer positioning posts 12 to ensure the positioning accuracy between the material strip 13 and the positioning posts 12;

[0069] Alternatively, the three positioning posts 12 are located at any three corners of the base 11, which further increases the positioning accuracy between the strip 13 and the positioning posts 12;

[0070] Alternatively, referring to Figure 6, the four positioning posts 12 are located at the four corners of the base 11, which can better ensure the positioning accuracy between the material strip 13 and the positioning posts 12.

[0071] Optionally, each of the positioning posts 12 is located on the 45-degree angle bisector of the corresponding angle of the base 11. This makes the positioning posts 12 reasonably positioned, which helps to accurately position the material strip 13 and the second suspension wire hole 72 on the first elastic connector 3.

[0072] Optionally, referring to Figures 7 to 9, the cross-sectional shape of the positioning post 12 along the axis perpendicular to the central axis can be, but is not limited to, circular, square, or groove-shaped. This makes the positioning post 12 more reasonably positioned, enabling better positioning of the material strip 13 and the second suspension wire hole 72 on the first elastic connector 3.

[0073] Optionally, the strip 13 has two connecting ends, both of which are connected to the second elastic connector 8; the positioning hole 132 is provided in the middle of the strip 13; this makes the connection between the strip 13 and the second elastic connector 8 relatively stable, which helps to achieve accurate positioning of the second suspension wire hole 72 on the first elastic connector 3;

[0074] Alternatively, the strip 13 may have a connecting end, with the positioning hole 132 located on the side of the strip 13 away from the connecting end. This helps improve the positioning efficiency of the second suspension hole 72 on the first elastic connector 3.

[0075] Optionally, referring to Figure 10, the strip 13 with two connecting ends is generally L-shaped, and the first suspension hole 71 is located on the inner side of the strip 13 and close to the second elastic connector 8. This makes the connection between the strip 13 and the second elastic connector 8 more stable, which helps to better ensure the positioning accuracy between the positioning hole 132 and the positioning post 12 on the strip 13.

[0076] Referring to Figure 12, the strip 13 with one connecting end is generally in a straight line shape. This makes the structure of the strip 13 relatively simple, which not only facilitates the connection between the strip 13 and the second elastic connector 8, but also helps to cut the strip 13 after the yarn is threaded.

[0077] Optionally, the movable component further includes a support 2 and a carrier 5;

[0078] The bracket 2 has a movable through hole in the middle, and the carrier 5 is embedded in the movable through hole; the bracket 2 and the carrier 5 are connected on the side away from the base 11 by the first elastic connector 3, and the bracket 2 and the carrier 5 are connected on the side closer to the base 11 by the second elastic connector 8.

[0079] In the above embodiments, the positions of the first elastic connector 3 and the second elastic connector 8 are reasonably set, which can ensure the stability of the elastic connection between the carrier 5 and the support 2, and can also absorb vibration and impact well.

[0080] Optionally, referring to Figure 11, a clearance structure 15 is provided at the position corresponding to the cutting area 131 of the material strip 13 on the support 2. The clearance structure 15 can be a notch, a through hole, or a hollow hole. The material strip 13 is exposed through the clearance structure 15, which facilitates the laser to pass through the support 2 to cut the material strip 13.

[0081] In the above embodiment, after the suspension wire 7 is threaded, that is, after the two ends of the suspension wire 7 are welded to the first suspension wire 7 of the base 11 and the second suspension wire hole 72 of the first elastic connector 3 respectively, the laser can cut the material strip 13 through the clearance structure 15 to ensure the normal function of the second elastic connector 8.

[0082] Optionally, the strip 13 and the second elastic connector 8 are integrally formed. This facilitates the processing of the strip 13 and the second elastic connector 8, reduces processing costs, and ensures the accuracy of the positioning of the strip 13.

[0083] Optionally, the first elastic connector 3 is an F spring;

[0084] The second elastic connector 8 is a B spring.

[0085] In the above embodiment, the stability of the elastic connection between the carrier 5 and the bracket 2 can be achieved by using spring F and spring B, thereby fixing and adjusting the position of the movable component to ensure the quality and stability of the lens imaging.

[0086] In one specific embodiment, the movable component further includes a magnet 4 and an AF coil 6. The magnet 4 is disposed on the inner side of the support 2, and the AF coil 6 is sleeved on the outer side of the carrier 5, with the AF coil 6 located in the gap between the carrier 5 and the magnet 4, that is, the AF coil 6 is located on the side of the magnet 4 closer to the carrier 5. The AF coil 6 is mainly used to realize the autofocus (AF) function. When the AF coil 6 is energized, it interacts with the magnet 4 to generate an electromagnetic force, which pushes the support 2 to move back and forth along the optical axis, thereby realizing autofocus. Furthermore, by controlling the magnitude and direction of the current in the AF coil 6, the focal length of the lens can be precisely adjusted.

[0087] For example, the stator assembly also includes an FPC 10 and an OIS coil 9. The FPC 10 is mounted on the base 11, and the OIS coil 9 is disposed on the FPC 10 (Flexible Printed Circuit). When the movable component is assembled into the stator assembly, the OIS coil 9 is located below the magnet 4. The OIS coil 9 is used to implement optical image stabilization (OIS). When the OIS coil is energized, it interacts with the magnet 4 to generate an electromagnetic force, pushing the bracket 2 back and forth in any direction perpendicular to the optical axis. This movement can counteract external vibrations during shooting (such as hand tremors), thereby maintaining image sharpness. The OIS coil 9 works in conjunction with the AF coil 6 to ensure stable lens focusing and reduce the effects of camera shake during shooting.

[0088] According to a second aspect of this disclosure, referring to Figures 1 and 2, a suspended wire OIS motor is provided, comprising:

[0089] Outer shell 1;

[0090] The stator assembly includes a housing 1 and a base 11 forming a receiving cavity; the stator assembly includes a base 11, and the base 11 has a first suspension wire hole 71 on the side facing the movable assembly; the base 11 has a positioning post 12, and the positioning post 12 is close to the first suspension wire hole 71.

[0091] A movable component is located within the receiving cavity. The movable component includes a suspension wire 7, a first elastic connector 3, and a second elastic connector 8. The first elastic connector 3 is provided with a second suspension wire hole 72. The first elastic connector 3 is disposed on the side of the movable component away from the base 11, and the second elastic connector 8 is disposed on the side of the movable component closer to the base 11.

[0092] The movable component is connected to the base 11 via the suspension wire 7; wherein the base 11 and the movable component are assembled using the suspension wire type OIS motor assembly method described in the first aspect.

[0093] In the above embodiments, the suspension wire type OIS motor is reasonably designed, which can significantly improve the efficiency of threading the suspension wire 7 and ensure the installation accuracy of the suspension wire 7, thus better ensuring the performance of the suspension wire type OIS motor.

[0094] It should be noted that for the existing suspension wire type OIS motor, when the suspension wire is severely eccentric to the holes at both ends, the wire threading process can easily cause the first elastic connector (such as the F spring) to deform. Moreover, when eccentric, even if the suspension wire passes through the hole, the suspension wire support system will pull the entire movable component at an angle, causing the OIS unit (in the XY plane) to be eccentric, thereby affecting the motor performance.

[0095] In this application, the suspension wire type OIS motor uses the cooperation between components (the positioning post 12 on the base 11 cooperates with the material strip 13 on the second elastic connector 8) to make the first suspension wire hole 71 of the base 11 and the second suspension wire hole 72 of the first elastic connector 3 concentric. When the suspension wire 7 passes through the hole, it can pass through quickly and effectively, effectively solving the following problems:

[0096] 1. The problem of the suspension wire not being able to pass through due to misalignment between the first suspension wire hole on the base and the second suspension wire hole on the first elastic connector (e.g., spring F). 2. Improved the efficiency of suspension wire threading. 3. Effectively solved the deformation of the first elastic connector caused by suspension wire threading, reducing performance issues such as stroke eccentricity, center offset, and linearity problems. 4. Effectively solved the problem of the suspension wire tilting after threading.

[0097] In one specific embodiment, the assembly process of the suspension-type OIS motor is as follows:

[0098] First, fix the OIS coil 9 to the FPC10 and install the FPC10 on the base 11. The OIS coil 9, FPC10 and base 11 together constitute the stator assembly.

[0099] Secondly, the magnet 4 is fixed to the bracket 2, and the magnet 4 and the bracket 2 together constitute a semi-finished magnetic circuit.

[0100] Next, the carrier 5, the first elastic connector 3, the second elastic connector 8, and the magnetic circuit semi-finished product are assembled together to form the AF component semi-finished product.

[0101] Next, the AF component semi-finished product, stator assembly, and suspension wire 7 are assembled together to form the OIS semi-finished product. In this process, the relationship between the bracket 2, the first elastic connector 3 (e.g., F spring), and the base 11 can be positioned without tooling fixtures. The material strip 13 connected to the second elastic connector 8 and the positioning post 12 can be used to align the first suspension wire hole 71 of the base 11 with the second suspension wire 7 of the first elastic connector 3, thus simplifying the suspension wire threading operation and significantly increasing the success rate. Simultaneously, it reduces deformation caused by the suspension wire 7 hitting the first elastic connector 3 and failing to pass through the second suspension wire hole 72, improving the efficiency of suspension wire threading and reducing performance defects caused by suspension wire threading problems.

[0102] Finally, the OIS semi-finished product is assembled with the housing 1 to form the finished motor (i.e., the suspension wire OIS motor).

[0103] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of this disclosure, and this disclosure is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of this disclosure, and these modifications and improvements are also considered to be within the scope of protection of this disclosure.
