Description

Camera actuator and camera module

[0001] Embodiments of the invention relate to a camera actuator and a camera.

[0002] A camera is a device that captures a subject as a photo or video, and is installed in portable devices, drones, vehicles, etc. Camera modules or camera devices may have an image stabilization (IS) function that corrects or prevents image shaking caused by the user's movement to improve the quality of the image, an auto focusing (AF) function that automatically adjusts the distance between the image sensor and the lens to align the focal length of the lens, and a zooming function that increases or decreases the magnification of a distant subject and captures it using a zoom lens.

[0003] Meanwhile, as image sensors move toward higher resolutions, the pixel size decreases. However, as pixels become smaller, the amount of light they can capture in a given amount of time decreases. Therefore, higher-megapixel cameras are more prone to image blur caused by camera shake, which occurs when shutter speeds are slower in dark environments. A representative example of image stabilization (IS) technology is optical image stabilizer (OIS), which compensates for movement by changing the path of light.

[0004] According to typical OIS technology, the movement of the camera is detected using a gyro sensor or the like, and based on the detected movement, the lens can be tilted or moved, or the camera module including the lens and image sensor can be tilted or moved. When the lens or the camera module including the lens and image sensor is tilted or moved for OIS, additional space for tilting or moving must be secured around the lens or camera module.

[0005] Meanwhile, the actuator for OIS may be positioned around the lens. The actuator for OIS may include an actuator responsible for tilting about an axis orthogonal to the optical axis. If the actuator for OIS moves the lens excluding the image sensor, image distortion occurs. In particular, the distortion occurs at the edges or corners. Furthermore, since the image sensor and the lens are separated and only one of them tilts, it is difficult to compensate for shake at a wide angle.

[0006] An embodiment of the invention provides a camera actuator and a camera module that support and move a lens carrier with an elastic spring for an AF function. An embodiment of the invention can provide a camera actuator and a camera module that support and tilt a lens carrier and holder with ball members for an OIS function. An embodiment of the invention can provide a camera actuator and a camera module that share an AF driving magnet with an OIS driving magnet.

Embodiments of the invention may provide a camera actuator and a camera module having a holding magnet and a holding yoke disposed between a sensor base and a housing.

[0010] An embodiment of the invention seeks to provide a camera actuator and a camera module for AF applicable to ultra-slim, ultra-small and high-resolution cameras.

[0011] A camera module according to an embodiment comprises: a housing; a moving plate disposed on the housing; a holder disposed on the moving plate; an image sensor disposed to be movable together with the holder; a lens carrier disposed inside the holder and including a lens; a first magnet disposed on the holder; a first coil disposed on the housing; and a second coil disposed on the lens carrier, wherein the lens carrier is moved in the optical axis direction relative to the holder by interaction between the first magnet and the second coil, and the holder and the image sensor can be tilted relative to the housing by interaction between the first magnet and the first coil.

[0012] According to an embodiment of the invention, the housing includes a driving substrate arranged on the bottom, the first coils are arranged on the inner side of at least two sides of the housing, and the driving substrate may include first to fourth extension portions extending outwardly from each of the first coils and connected to each of the first coils.

[0013] According to an embodiment of the invention, the lens carrier may include a second magnet disposed on a first corner between adjacent sides of the lens carrier, and a position detection sensor facing the second magnet; and a sub-substrate having the position detection sensor and disposed on the first corner between adjacent sides of the holder.

[0014] According to an embodiment of the invention, the substrate includes a substrate portion on which the image sensor is mounted, and the sub-substrate may have a plurality of outer pads electrically connected to pads of the substrate portion on the outside.

[0015] According to an embodiment of the invention, the sub-substrate may include guide grooves on both sides, and substrate guide protrusions coupled to the guide grooves of the holder.

[0016] According to an embodiment of the invention, the lens carrier may have a balancing magnet disposed at a second corner between adjacent other sides.

[0017] According to an embodiment of the invention, the holder and the lens carrier include first and second moving guide parts coupled to the upper portions thereof, and each of the first and second moving guide parts may have a plurality of elastic springs.

[0018] According to an embodiment of the invention, both terminals of the second coil may protrude through the lens carrier and be electrically connected to the first and second moving guide parts, respectively.

[0019] According to an embodiment of the invention, one end of each of the first and second moving guide parts can be electrically connected to an inner pad of the sub-substrate.

[0020] According to an embodiment of the invention, the lens carrier has a plurality of protrusions protruding from the upper portion, and the plurality of protrusions have an inwardly convex curved surface and can be bonded to the center of each of the elastic springs.

[0021] According to an embodiment of the invention, the holder and the lens carrier include a third moving guide part coupled to the lower part, and the third moving guide part may have a plurality of elastic springs.

[0026] The camera actuator and camera module of the embodiment can eliminate image distortion depending on the OIS operating mode. Furthermore, by tilting the lens carrier and image sensor, it effectively compensates for shake at wide angles and wide bandwidths. Furthermore, it can reduce power consumption, reduce load, and improve heat generation.

[0027] The camera actuator and camera module of the embodiment can reduce shock by arranging a moving plate and a sensor base below a substrate portion where an image sensor is arranged. In addition, since the moving plate and the sensor base are combined in a molded structure, the molded structure can prevent detachment due to external shock and alleviate secondary shock. In addition, by arranging a holding magnet and a holding yoke facing each other at the center of the sensor base, the moving plate and the driving unit can be fixed.

[0028] By sharing the magnet for OIS of the invention with the magnet for AF, the size of the camera actuator and camera module can be reduced. This improves the reliability of the camera actuator and camera module of the invention, and can improve the reliability of portable electronic devices such as mobile communication terminals, smart phones, and tablet PCs having the camera module, as well as movable electronic devices such as vehicles, ships, and drones.

For example, the moving plate (200) can rotate (Pitch) on both sides in the first direction (X) based on the second direction (Y). The moving plate (200) may not rotate on both sides in the second direction (Y) based on the first direction (X). In addition, the sensor base (300) can rotate (Yaw) on both sides in the second direction (Y) based on the first direction (X) on the moving plate (200). Such rotation (Yaw, Pitch) in the first and second directions (X, Y) can be implemented by the electromagnetic force of the driving unit (810-840).

[0094] The second coil (C5) is arranged along the side of the lens carrier (500) and can move the lens carrier (500) up or down in the optical axis direction.

A yoke (not shown) may be provided on the outer side of each of the first to fourth extension portions (951-954) so ​​as to overlap the first to fourth coils (C1-C4) in the first and second directions (X, Y). The yoke has a magnetic material and can exert an attractive force on each of the opposing magnets (M1-M4).

[0097] The first to fourth coils (C1) to (C4) can be coupled to recesses (581) disposed on each side surface (S1 to S4) of the housing (100). The recesses (581) may be holes through which each side surface (S1 to S4) of the housing (100) penetrates from the inside to the outside. The second coil (C5) can be coupled along a concave portion (C51) disposed along the inner side surface of the lens carrier (500). The concave portion (C51) has a shape that is concave inward on the side surface of the lens carrier (500) and may be continuously disposed along the side surface of the lens carrier (500). The first to fourth magnets (M1) to (M4) can be coupled to recesses (181) disposed on each side surface (S1 to S4) of the holder (400).

The first position detection sensor may include first to fourth position detection sensors (H1 to H4). The first to fourth position detection sensors (H1 to H4) are electrically connected to the first to fourth extensions (951 to 954) of the driving substrate (950) and face the first to fourth magnets (M1 to M4). The first to fourth position detection sensors (H1 to H4) may detect position information of each of the first to fourth magnets (M1 to M4) and provide the detected position information through the driving substrate (950). The first to fourth position detection sensors (H1 to H4) may be hall sensors. In addition, temperature sensors (T1, T2) may be arranged in at least one or more regions among the inner regions of the 1-1 coil (C1) to the 1-4 coil (C4).

Accordingly, the first to fourth sub-frames (712, 714, 722, 724) can be fixed to the lens carrier (400).

[0119] The upper surface of the lens carrier (400) has a plurality of support protrusions (P1-P4), and the first to fourth sub-frames (712, 714, 722, 724) can be respectively mounted on each of the support protrusions (P1-P4). As shown in Fig. 27, the first to fourth sub-coupling protrusions (51, 54, 51A, 54A) can protrude in the object direction from each of the support protrusions (P1-P4). The first to fourth sub-coupling protrusions (51, 54, 51A, 54A) can have a columnar shape, for example, a circular columnar shape or a polygonal columnar shape.

[0120] The support protrusions (P1-P4) of the holder (500) have a concave step portion (58) on some of them, and an adhesive can be placed on the step portion (58).

The first terminal (C51) may protrude into the terminal hole (591) of the first sub-frame (712) and may be joined to the first sub-frame (712) by a joining member (not shown). The first terminal (C51) may be electrically connected to the first and second frame parts (F1, F2) of the first movement guide part (710) through the first elastic spring (711). Accordingly, the first terminal (C51) of the second coil (C5) may be electrically connected to the first movement guide part (710).

[0122] The second terminal (C52) of the second coil (C5) protrudes into the terminal hole (593) of the third sub-frame (722) and can be joined to the third sub-frame (722) by a joining member (not shown). The second terminal (C52) can be electrically connected to the third and fourth frame parts (F3, F4) of the second movement guide part (720) through the third elastic spring (721). Accordingly, the second terminal (C52) of the second coil (C5) can be electrically connected to the second movement guide part (720).

[0123]

[0124] As shown in FIGS. 10 to 12, the lens carrier (500) has a sensing magnet (MS1) and a balancing magnet (MS2). The sensing magnet (MS1) is disposed on a first corner (K1) of the lens carrier (500) and can provide the position of the lens carrier (500) to the second position detection sensor (H5). The balancing magnet (MS2) of the lens carrier (500) can be disposed on a second corner (K2) which is an area opposite to the first corner (K1). That is, the balancing magnet (MS2) can balance the weight with the sensing magnet (MS1) and stabilize the movement of the lens carrier (500). As shown in Fig. 13, the first corner (K1) and the second corner (K2) of the lens carrier (500) may be cut-out areas between the side surfaces. The third corner (K3) and the fourth corner (K4) of the lens carrier (500) may be opposite corners, and may be cut-out areas between the side surfaces. The balancing magnet (MS2) may have the same size as the sensing magnet (MS1), and may balance the lens carrier (500) due to the weight of the sensing magnet (MS1). The sensing magnet (MS1) may be defined as a second magnet.

[0125]

[0126] As shown in FIGS. 10, 11, and 27, the lens carrier (500) has a plurality of protrusions (50, 60) protruding in the optical axis direction from the upper surface, and the plurality of protrusions (50, 60) include a first protrusion (50) adjacent to the first corner (K1) and a second protrusion (60) adjacent to the second corner (K2). The first protrusion (50) may have the sensing magnet (MS1) coupled therein. The sensing magnet (MS1) may have bipolarity and may be exposed to the upper surface, lower surface, and outer surface of the first protrusion (50). The second protrusion (60) may have the balancing magnet (MS2) coupled therein. The balancing magnet (MS2) may have bipolarity and may be exposed to the upper surface, lower surface, and outer surface of the second protrusion (50).

[0127] The first protrusion (50) has a first guide protrusion (50A) on the inside, and the first guide protrusion (50A) has a hemispherical shape protruding inward, and the inner surface of the first guide protrusion (50A) can have a curvature corresponding to the center (R4) of the curved shape of the fourth elastic spring (723). The first guide protrusion (50A) and the center (R4) of the fourth elastic spring (723) are bonded with an adhesive (not shown), and the center (R4) of the fourth elastic spring (723) can be fixed to the first guide protrusion (50A). Accordingly, when one or the other end of the fourth elastic spring (723) moves in the direction of the optical axis, the center (R4) of the fourth elastic spring (723) fixed by the first guide protrusion (50A) can be suppressed from affecting other areas of the fourth elastic spring (723).

[0128] The second protrusion (60) has a second guide protrusion (60A) on the inside, and the second guide protrusion (60A) has a shape that protrudes hemispherically toward the inside, and the inner surface of the second guide protrusion (60A) can have a curvature corresponding to the center (R3) of the curved shape of the second elastic spring (713). The second guide protrusion (60A) and the center (R3) of the second elastic spring (713) are bonded with an adhesive (not shown), and the center (R3) of the second elastic spring (713) can be fixed to the second guide protrusion (60A). Accordingly, when one or the other end of the second elastic spring (713) moves in the direction of the optical axis, the center (R3) of the second elastic spring (713) fixed by the second guide protrusion (60A) can be suppressed from affecting other areas of the second elastic spring (713).

[0129] The lens carrier (500) may have a third guide protrusion (52) on an upper surface adjacent to the third corner (K3), and a fourth guide protrusion (52A) on an upper surface adjacent to the fourth corner (K4). The inner surface of the third guide protrusion (52) may have a hemispherical curve and may have a curvature corresponding to the center (R1) of the first elastic spring (711). The third guide protrusion (52) and the center (R1) of the first elastic spring (711) may be fixed to the third guide protrusion (52) using an adhesive (not shown). Accordingly, when one end or the other end of the first elastic spring (711) moves in the optical axis direction, the center (R1) of the first elastic spring (711) fixed by the third guide protrusion (52) can be suppressed from affecting other areas of the first elastic spring (711).

[0130] The inner surface of the fourth guide protrusion (52A) may have a hemispherical curve and may have a curvature corresponding to the center portion (R2) of the third elastic spring (721). The third guide protrusion (52A) and the center portion (R2) of the third elastic spring (721) may be fixed to the fourth guide protrusion (52A) using an adhesive (not shown). Accordingly, when one end or the other end of the third elastic spring (721) moves in the direction of the optical axis, the center portion (R2) of the third elastic spring (721) fixed by the fourth guide protrusion (52A) may be prevented from affecting other areas of the second elastic spring (721).

[0131]

[0132] As shown in Fig. 24, the end (FC1) of the first movement guide part (710) faces the inner pad (PD11) of the sub-substrate (970) and can be joined to the inner pad (PD11) by a joining member (not shown). The end (FC2) of the second movement guide part (720) faces the inner pad (PD12) of the sub-substrate (970) and can be joined to the inner pad (PD12) by a joining member (not shown). Accordingly, the first and second movement guide parts (710, 720) can electrically connect the second coil (C5) and the sub-substrate (970). As shown in Fig. 25, the sub-substrate (970) has outer pads (PD2) on the outer lower side, and the outer pads (PD2) can be respectively bonded to the pads (PD3) of the sub-connection substrate (971) of the substrate portion (910) using a bonding member (not shown). Accordingly, the sub-substrate (970) can be electrically connected to the substrate portion (910).

[0133]

[0134] The sub-substrate (970) is placed at a first corner (K1) among the corners of the holder (400), and the first corner (K1) has a substrate guide protrusion (P11) protruding on both lower outer sides, and the substrate guide protrusion (P11) can be combined with a guide groove (970A) of the sub-substrate (970). The sub-substrate (970) is a substrate for AF and can be provided as a flexible substrate. The sub-substrate (970) has a second position detection sensor (H5) on the inner side, and the second position detection sensor (H5) can face the sensing magnet (MS1). The second position detection sensor (H5) can detect the position of the sensing magnet (MS1) and provide detected position information. The above sub-substrate (970) is equipped with a third temperature sensor (T3), and the third temperature sensor (T3) can detect a temperature generated in an area between the first sub-substrate (970) and the second coil (C5) and provide temperature information. The second position detection sensor (H5) can be a Hall sensor.

[0135]

[0136] As shown in FIGS. 13 to 15 and 28, the bottom surface of the lens carrier (500) has a plurality of lower support protrusions in an area adjacent to the center of each side surface, and the plurality of lower support protrusions are fifth to eighth support protrusions (P5-P8), and can protrude from the bottom surface of the lens carrier (500) toward the bottom of the housing. Each of the fifth to eighth support protrusions (P5-P8) has a fifth to eighth engaging protrusion (91-94) protruding toward the bottom of the housing, and the fifth to eighth sub-engaging protrusions (91-94) can have a columnar shape, for example, a circular columnar shape or a polygonal columnar shape. The third movement guide part (750) is in close contact with the fifth to eighth support protrusions (P5-P8), and the fifth to eighth engaging protrusions (91-94) can be engaged with the third movement guide part (750). The outer portions of the fifth to eighth coupling protrusions (91-94) have a step portion (59), and an adhesive (not shown) can be applied to the step portion (59) to fix the third moving guide portion (750). Each corner of the bottom surface of the lens carrier (500) can have a concave area (R51) that exposes the second coil (C5).

[0137]

[0138] The third moving guide part (750) may have a ring-shaped body (755) arranged around the opening (501) of the lens carrier (500), a plurality of fixed frames (765-768) connected to the body (755), and a plurality of elastic springs (751-754) connected to each of the plurality of fixed frames (765-768). Each of the plurality of fixed frames (765-768) has a coupling hole (95) and may be coupled with a coupling protrusion (91-94) of the lens carrier (500).

[0139] Each of the plurality of elastic springs (751-754) may have one end connected to the fixed frame (765-768), and the other end connected to each of the plurality of sub-fixed frames (761-764). The plurality of sub-fixed frames (761-764) may be arranged on each corner of the lens carrier (500) and may be coupled to each corner of the holder (400). That is, each of the coupling holes (85) of the plurality of sub-fixed frames (761-764) may be coupled to a coupling protrusion (81-84) arranged on each corner of the holder (400). The coupling holes (85) of the plurality of sub-fixed frames (761-764) may have a circular shape or a polygonal shape.

[0140] The above plurality of sub-fixed frames (761-764) may include a first sub-fixed frame (761) arranged in an area between the 1-1st and 1-3rd magnets (M1, M3), a second sub-fixed frame (762) arranged in an area between the 1-2nd and 1-4th magnets (M2, M4), a third sub-fixed frame (763) arranged in an area between the 1-2nd and 1-3rd magnets (M2, M3), and a fourth sub-fixed frame (764) arranged in an area between the 1-1st and 1-4th magnets (M1, M4). The shapes of the first and second sub-fixed frames (761, 762) may have the same shape, and the shapes of the third and fourth sub-fixed frames (763, 764) may have the same shape. The shapes of the first and second sub-fixed frames (761, 762) may have different shapes from the shapes of the third and fourth sub-fixed frames (763, 764).

[0141] The gap between the first-first and first-third magnets (M1, M3) and the gap between the first-second and first-fourth magnets (M2, M4) may be smaller than the gap between the first-second and first-third magnets (M2, M3) and the gap between the first-first and first-fourth magnets (M1, M4).

[0142] The width (D2, see FIG. 14) of the open area disposed at the first and second corners (K1, K2) of the holder (400) may be smaller than the width (D1, see FIG. 14) of the open area disposed at the third and fourth corners (K3, K4) of the holder (400). The third and fourth sub-fixed frames (763, 764) having a width greater than the width (D2) may be disposed at the open areas of the first and second corners (K1, K2) of the holder (400). The first and second sub-fixed frames (761, 762) having a width greater than the width (D1) may be disposed at the open areas of the third and fourth corners (K3, K4) of the holder (400).

[0143] The first and second sub-fixed frames (761, 762) of the third moving guide part (750) have an outer part (SR1), an inner part (SR2), and an intermediate part (SR2) between the outer part (SR1) and the inner part (SR2), and the width of the intermediate part (SR2) may be smaller than the maximum width of the outer part (SR1) and the inner part (SR2). Accordingly, the first and second sub-fixed frames (761, 762) of the third moving guide part (750) may be suppressed from moving inward or outward.

[0144] The third moving guide part (750) may be formed integrally with a ring-shaped body (755), the plurality of elastic springs (751-754), the plurality of fixed frames (765-768), and the plurality of sub-fixed frames (761-764). The third moving guide part (750) may be formed of the same material as the first and second moving guide parts (710, 720) or may be formed of a different metal material. As another example, the third moving guide part (750) may be formed as a single body or divided into two.

[0145]

[0146] As shown in FIG. 16 and FIG. 30, the bottom of the driving substrate (950) has a plurality of through holes (956, 957) spaced apart in the first direction, and has a bottom support portion (197A, 197B) and a bottom hole (197) of the housing (100) inside the plurality of through holes (956, 957).
