Description

Image sensor actuator for OIS and camera module including the same {IMAGE SENSOR ACTUATOR FOR OIS AND CAMERA MODULE INCLUDING IT}

The present invention relates to an image sensor actuator for OIS and a camera module including the same, and more specifically, an actuator implementing OIS through binary driving by linear and rotational movement of an image sensor, and a camera module including the same. For.

As hardware technology for image processing advances and user needs for video recording increase, autofocus (AF), etc., to camera modules mounted on mobile terminals such as mobile phones, smartphones, as well as independent camera devices, Functions such as optical image stabilization (OIS) are being implemented.

The auto focus (auto focus control) function allows a carrier equipped with a lens, etc., to move linearly in the direction of the optical axis and adjust the focal length to the subject so that a clear image is generated by an image sensor (CMOS, CCD, etc.) provided at the rear end of the lens. Means function.

In addition, the image stabilization function refers to a function of improving the clarity of an image by adaptively moving a carrier on which a lens is mounted in a direction that compensates for the shake when a lens shake occurs due to the shake.

One of the representative methods of implementing the autofocus or OIS function is to install a magnet (coil) on a moving body (carrier), and a coil (magnet) on a fixed body (housing or other type of carrier), and then the coil and magnet. It is a method of moving the moving object in the optical axis direction or in a direction perpendicular to the optical axis by generating electromagnetic force therebetween.

On the other hand, in the case of a zoom lens, unlike a general lens, since a plurality of lenses or lens groups are arranged coaxially in the direction of the optical axis, which is the direction in which light is introduced, the length thereof is significantly extended in the optical axis direction than a general lens.

The light of the subject passing through the zoom lens flows into an image sensor (imaging device) such as CCD (Charged-coupled Device) and CMOS (Complementary Metal-Oxide Semiconductor) like other lenses, and is converted into image data through subsequent processing. Is created.

If the zoom lens is installed in a direction that stands on the main board of the mobile terminal, that is, in a direction perpendicular to the main board like other general lenses, the mobile terminal has a space equal to the height of the zoom lens (length in the optical axis direction). Therefore, there is a problem that it is difficult to optimize the essential characteristics of device miniaturization and weight reduction aimed at by portable terminals.

In order to solve this problem, recently, as shown in Figs. 1(a) and (b), an optical system 11 reflecting light of a subject incident in the Z2-axis (-Y1-axis direction) direction to the lens module 12. ) Is provided at the front end of the camera module 50 and the light of the subject passing through the lens module 12 flows into the image sensor 13 (in the Z1-axis direction).

In this configuration, the camera module 50 is not installed in a manner in which the camera module 50 is installed on the main board of the mobile terminal 10 (Y1-axis direction), but the horizontal direction (Z1-axis direction) of the mobile terminal 10 or It is possible to mount the camera module 50 in a manner in which the camera module 50 is laid in a vertical direction (X1-axis direction), thereby increasing space utilization.

Meanwhile, in this embodiment, an OIS of a method of moving the lens module 50 or moving the optical system 11 is typically applied as in a conventional method.

However, in this case, since the moving object is heavy and bulky, power efficiency is low, and additional space for driving is required, so it does not meet the miniaturization of the device. It can be said that there is a problem in that there is a limitation in rapid drive control.

In addition, the OIS drive has the characteristic of moving numerous and repetitively over a short period of time, so in the case of a conventional device that physically moves the optical system 11 implemented with a glass material, physical damage or damage to the optical system 11 itself occurs easily. In addition, it can be said that there is a problem in that the reliability of the actuator or the camera module itself including the same may be deteriorated because a malfunction or the like may occur due to broken fine debris.

The present invention is invented to solve the above-described problems in the background as described above, and implements OIS using a relatively light and not bulky image sensor as a moving object, and furthermore, a configuration and structure for driving OIS Its purpose is to provide an image sensor actuator for OIS that can further optimize OIS drive performance and further optimize the space utilization of the actuator itself by implementing only a minimized space conforming to the shape characteristics.

Is a diagram showing the structure of the actuator 100 according to the present invention.

The camera module 1000 according to the present invention may include an optical system module 200 and an actuator 100, and the optical system module 200 includes a lens assembly and a light of the subject as described above. When introduced (in the Z2-axis direction), a reflectometer (mirror, prism, etc.) may be included to reflect the path toward the lens assembly in the direction (Z1-axis direction).

As described above, the actuator 100 of the present invention is provided at the rear end (based on the Z1-axis direction in Fig. 2) of the optical system module 200 including a lens assembly, and corrects movement due to shaking when a shake phenomenon such as hand shake occurs. By moving the image sensor 300 in the direction to implement the OIS function.

2 and 3, the actuator 100 of the present invention includes the housing 110, the main circuit board 120, the first coils 123-1 and 123-2, the second coil 128, and the first A carrier 130, a first magnet (133-1, 133-2, see FIG. 4), a second carrier 140, a second magnet 148 (see FIG. 6), and an elastic body 150 may be included.

Hereinafter, as shown in the Z-axis direction of FIG. 3, an axis in a direction corresponding to a direction in which light flows into the image sensor 300 is defined as an optical axis, and a direction perpendicular to the optical axis is an X-axis (first direction) and a Y-axis ( The second direction) is defined and described.

As described above, when the first carrier 130 moves linearly in the first direction, the image sensor 300 mounted on the second carrier 140 also moves linearly in the first direction, so the component in the first direction (X-axis direction) Image stabilization (OIS) is implemented.

On the other hand, since the second direction (Y-axis direction) corresponds to the thickness direction of the portable terminal, it is difficult to sufficiently secure a space in the Y-axis direction due to the slimming tendency of the portable terminal. Therefore, in this state, if the OIS in the second direction (Y-axis direction) is implemented by linear movement requiring sufficient movement space, the thickness of the actuator or camera module itself increases, causing a problem of increasing the thickness of the portable terminal. Can be.

As briefly described above, the second carrier 140 of the present invention rotates based on the first carrier 130, but rotates based on a rotation axis (RA, see FIG. 7) in a direction corresponding to the first direction. Corresponds to a moving object that moves. In this respect, with respect to the second direction OIS, the first carrier 130 of the present invention corresponds to a fixed body, and the second carrier 140 corresponds to a moving body from a relative perspective.

Therefore, based on the entire OIS, the first carrier 130 of the present invention functions as a moving body for the OIS in the first direction and as a fixed body for the OIS in the second direction.

As shown in FIG. 6, a second magnet 148 facing the second coil 128 is provided under the second carrier 140, and the OIS driving in the second direction is performed by the main circuit board 120. It is implemented by an electromagnetic force between the second coil 128 mounted on the second coil 128 and the second magnet 148 installed on the second carrier 140.

The second ball 170 of the present invention is disposed between the first rotation guide 137 of the first carrier 130 and the second rotation guide 147 of the second carrier 140. Unlike the first ball 160 that guides the linear movement of the moving object, the second ball 170 of the present invention functions as a reference point at which the rotational movement of the second carrier 140 is performed. do.

That is, the second carrier 140 of the present invention rotates with respect to the first carrier 130 while facing the second ball 170.
