Description

Technical Field

[0001] The present invention relates to a camera actuator and a camera module including the same. Background Art

[0002] A camera is a device that captures still and moving images of a subject, and is mounted on portable devices, drones, automobi les and the like. In order to improve image quality, a camera module is provided with a user's Image Stabilization (IS) function that corrects or prevents image blur caused by movement, and an Auto Focusing (AF) function that automatically adjusts the distance between an image sensor and a lens to align the foca l length of the lens, and a zooming function that increases or decreases the magnification of a distant subject through a zoom lens to capture the image, which can be provided in the camera module. .

[0003] On the other hand, as the number of pixels of an image sensor increases, the resolution becomes higher and the size of each pixel becomes smaller, and as the pixel size decreases, the amount of light received during the same period of time decreases. Therefore, for a higher-pixel camera, the shutter speed becomes slower in dark environments, and image blurring caused by hand shake that occurs as a result becomes more pronounced. A representative example of image stabilization (IS) technology corrects movement by changing the path of light. One such representative technology is Optical Image Stabilizer (OIS) technology.

[0004] According to general OIS technology, camera shake is detected through a gyrosensor or the like, It senses the movement of the camera and tilts or moves the lens based on the sensed movement, or the lens and The camera module, including the image sensor, can be tilted or moved. A camera module including a lens and image sensor tilts or moves for OIS. In addition, space is provided around the lens or camera module for tilting or movement. It is necessary.

[0005] On the other hand, actuators for OIS can be placed around the lens. In this case, O The actuator for IS has two axes perpendicular to the optical axis Z, i.e., X-axis tilt. This may include an actuator responsible for one movement and an actuator responsible for Y-axis tilting.

[0006] However, depending on the needs of ultra-slim and ultra-compact camera modules, active OIS There are significant spatial constraints for positioning the tuner, and the lens or the lens and image sensor The camera module itself, including the camera module, is guaranteed to have sufficient space to tilt or move for OIS. It can be difficult to capture. Also, the higher the pixel count of the camera, the more light is received, so the lens While a larger size is preferable, the space occupied by the actuator for OIS Therefore, there may be limits to how large the lens size can be made.

[0007] Furthermore, the camera module includes zooming, autofocus, and optical image stabilization (OIS) functions. In this case, the OIS magnet and the AF or zoom magnet are positioned close to each other. Furthermore, this can cause problems such as magnetic field interference.

[0008] Furthermore, in the case of a lens movement system, a hall sensor is used to sense the position and movement of the lens. Use a Hall sensor.

[0009] Such a Hall sensor is connected to a driver IC to acquire lens position information. The acquired location information is transmitted to the driver IC.

[0010] In the past, the driver IC and the Hall sensor were mounted on different substrates. Although they were implemented in the past, recently, to reduce noise and minimize bulk, driver ICs have been used. The Hall sensor and the circuit board tend to be mounted on the same board. Numerous pads are formed there, and these pads are connected to the driver IC, and the holes The sensor is connected to the driver IC. That is, the driver IC and the Hall sensor When the Hall sensor and the pack are placed on the same substrate, the substrate has a pack directly connected to the Hall sensor. The "do" does not exist.

[0011] Here, the Hall sensor is SMT (Surface Mount Technology) It is mounted on the substrate via (ogy), etc. At this time, the SMT process of the Hall sensor A short-circuit failure rate of about 3% to 4% occurs. However, the aforementioned circuit boards have a Hall sensor There is no pad connected to the sensor, and therefore the mounting state of the Hall sensor is not determined. There is a problem in that it cannot be stopped. In other words, the implementation state of the Hall sensor is Hall This is confirmed by measuring the resistance, but in order to confirm the mounting state of the Hall sensor, The test must be carried out via the pads connected to the driver IC. However, The pad is not directly connected to the Hall sensor but rather to the Hall sensor via a driver IC. It is connected to the sensor, and therefore, direct testing of the Hall sensor is not possible. problem.

[0012] On the other hand, the Hall sensor described above is arranged on a substrate together with a coil. Specifically, the hal l sensor is arranged in an inner region of the coil on the substrate. And the movement of the lens is performed by an electromagnetic force generated between the coil and the magnet. At this time, the electromagnetic force will be affected by the separation distance between the coil and the magnet. In addition, the magne tic flux of the magnet detected by the Hall sensor changes according to the separation distance between the Hall sensor and the magnet magnet flux changes, which affects the position sensing performance of the Hall sensor .

[0013] In this regard, in the conventional art, the height of the coil had to be ensured to secure thrust . At this time, as the height of the coil increases, the separation distance between the magnet and the Hall sensor increases, which causes a problem that the position sensing performance is degraded. Summary of the Invention Problem to be Solved by the Invention

[0070] The first camera module may include one or more actuators. For example, The first camera module includes a first camera actuator 1100 and a second camera actuator It may include -1200.

[0071] The second camera module is then placed in a predetermined housing (not shown), and the lens section It may include an actuator (not shown) capable of driving the voice coil motor. These can be electrostatic, microactuators, silicon actuators, etc., and are thermal actuators. It can be applied to various methods such as the 3D method, bimorph method, and electrostatic force method, and is not limited to these. It does not mean that. Furthermore, in this specification, camera actuator refers to actuators, etc. It can be mentioned that a camera module consisting of multiple camera modules is It can be implemented in various electronic devices such as mobile terminals.

[0072] Referring to Figure 3, the camera module according to the embodiment has a first camera that performs OIS function. The 1100 is a second camera that performs zooming and autofocus functions. It may include a Mera actuator 1200.

[0073] Light enters through an aperture region located on the upper surface of the first camera actuator 1100. Light can be incident on the camera module or the first camera actuator. That is, the light is on the optical axis. It is incident into the interior of the first camera actuator 1100 along a direction (for example, the X-axis direction). The optical path can be changed in the vertical direction (for example, the Z-axis direction) via an optical element. It passes through the second camera actuator 1200 and the second camera actuator 1200 The image sensor IS located at one end may be affected by the (PATH)

[0074] In this specification, the bottom surface means one side in the first direction. The first direction is as shown in the drawings. This is the X-axis direction and may be confused with the second axis direction, etc. The second direction is the Y-axis direction on the drawing. It can be used interchangeably with the first axial direction, etc. The second direction is perpendicular to the first direction. Also, the third direction The direction is the Z-axis direction on the drawing and can be confused with the third axis direction, etc. And the third direction is the This direction is perpendicular to both the first and second directions. Here, the third direction (Z-axis direction) is light. Corresponding to the direction of the axis, the first direction (X-axis direction) and the second direction (Y-axis direction) are perpendicular to the optical axis. It can be tilted by the second camera actuator. In addition, the horizontal direction is first and It can mean two directions, and the vertical direction is at least one of the first and second directions. It can mean the direction and the direction perpendicular to it. For example, the horizontal direction is the x-axis and y-axis of the drawing. This can mean the axial direction, the vertical direction is the z-axis direction in the drawing, and the x-axis and y-axis direction It can be in a direction perpendicular to the direction. Also, below, the first camera actuator 1100 and In the description of the 2 camera actuator 1200, the optical axis direction is the third direction (Z-axis direction). This is the direction, and the following explanation will be based on this.

[0075] Furthermore, in this specification, the inner side is the direction from the cover CV toward the first camera actuator. The direction can be such that the outside is the opposite direction to the inside. That is, the first camera actuator and The second camera actuator is located inside the cover CV, and the cover CV is located inside the first camera actuator It may be located outside the tuner or the second camera actuator.

[0076] And with this configuration, the camera module according to the embodiment changes the path of light. This improves the spatial limitations of the first and second camera actuators. This is possible. In other words, the camera module according to the embodiment can respond to changes in the path of light. The thickness of the La Module can be minimized while expanding the optical path. Furthermore, the second camera The actuator controls the focus and other parameters with an extended optical path to provide a wide range of magnification. It is important to understand that both options are available.

[0077] Furthermore, the camera module according to the embodiment has a first camera actuator that controls the optical path OIS can be realized through control, and therefore, decenter This minimizes the occurrence of tilt phenomena and allows for the best possible optical performance. .

[0079] Furthermore, the second camera actuator 1200 is equipped with a coil and a magnet, and It can perform a rate zooming function.

[0080] For example, the first lens assembly and the second lens assembly include a coil, a magnet, and It could be a moving lens that moves through a guide pin, and the third lens The lens assembly may, but is not limited to, a fixed lens. For example, the third The lens assembly performs the function of a focator, which focuses light onto a specific location. The first lens assembly can then focus an image with the third lens assembly, which is a condenser. The function of a variator is to refocus the image in another location. Yes, it is possible. However, in the first lens assembly, the distance to the subject or the image distance changes significantly, and double The rate can change significantly, and the first lens assembly, which is a multiplier, affects the focal length of the optical system. It can play an important role in separation or magnification changes. The image point may vary slightly depending on the position. As a result, the second lens assembly Furthermore, it can perform positional compensation for the image formed by the multiplier. For example, the second re The lens assembly projects the image point formed by the first lens assembly, which is a magnifier, to the actual image. The compensator plays a role in precisely imaging the position of the image sensor. It can perform the function. For example, the first lens assembly and the second lens assembly, It can be driven by the electromagnetic force resulting from the interaction between the coil and the magnet. The details described above will be explained later. This can be applied to the lens assembly. Also, the first lens assembly to the third lens assembly The bri can move along the optical axis direction, i.e., the third direction. And the first lens assembly The third lens assembly can move in the third direction independently or in conjunction with each other. .

[0081] On the other hand, according to embodiments of the present invention, the actuator for OIS and the actuator for AF or Zoom If an ETAR is present, magnetic field interference with the AF or zoom magnet may occur during OIS operation. This can be prevented. The first drive magnet of the first camera actuator 1100 is connected to the second camera Since it is positioned separately from actuator 1200, the first camera actuator 110 Magnetic field interference between the 0 and the second camera actuator 1200 can be prevented. OIS stands for Image Stabilization, Optical Image Stabilization, Optical Image Correction, and Shake Correction. It can be confused with terms such as these.

[0090] The first member 1126 may be placed in the first housing 1120. The first member 1126 is The second member 1131a may be placed between the housing. The first member 1126 is located between the housing It may be placed within or included in the g. The first member 1126 is by the second member 1131a It can be connected to the holder 1131. The first member 1126 is penetrated by the second member 1131a. The second member 1131a can be connected to the holder 1131. This allows the first member 112 At least a portion of 6 may be located between the second member 1131a and the holder 1131. An explanation of this will follow later.

[0091] The mover 1130 is attached to the holder 1131 and the optical component attached to the holder 1131. Includes 1132.

[0092] The holder 1131 can be securely attached to the housing portion 1125 of the first housing 1120. -1131 is the first housing side 1121, the second housing side 1122, the third housing The outer surface of the first holder to the fourth holder, corresponding to the side portion 1123 and the first member 1126, respectively. This may include the outer surface of the holder. For example, the outer surface of the first holder to the outer surface of the fourth holder may be the first holder. Zing side portion 1121, second housing side portion 1122, third housing side portion 1123, 1 The inner surfaces of each member 1126 can correspond to or face each other.

[0093] Furthermore, the holder 1131 may include a second member 1131a positioned in the fourth anchoring groove. A more detailed explanation of this will follow later.

[0094] The optical component 1132 can be securely attached to the holder 1131. Therefore, the holder 1131 It may have an attachment surface, and the attachment surface may be formed by a receiving groove. In the embodiment, the optical member 1132 is It can consist of a mirror or a prism. In the following, we will refer to it as a prism. Although shown as a standard, it can also consist of multiple lenses as in the example described above. Yes, it is possible. Alternatively, the optical component 1132 may consist of multiple lenses and a prism or mirror. Furthermore, the optical component 1132 may include a reflective portion disposed inside. However, it is not limited to this. It's not something that can be done.

[0095] Furthermore, the optical element 1132 receives light reflected from the outside (for example, an object) into the camera module. It can be reflected into the interior of the light. In other words, the optical member 1132 is the path of the reflected light The changes were made to improve the spatial limits of the first and second camera actuators. This allows the camera module to minimize thickness while shaping the light path. It should be understood that it can also be extended to provide a wide range of magnification.

[0096] In addition, the second member 1131a can be connected to the holder 1131. The second member 1 may be positioned on the outside of the holder 1131 and on the inside of the housing. 131a is located on the outer surface of the fourth holder, excluding the area of ​​the fourth fixing groove, relative to the holder 1131. It can be secured in the additional groove. Through this, the second member 1131a and the holder 1131 They are joined together, and between the second member 1131a and the holder 1131, there is a small portion of the first member 1126. Parts of both may be located. For example, at least a part of the first member 1126 may be located in the second member 113 It can penetrate the space formed between 1a and holder 1131.

[0097] Furthermore, the second member 1231a may have a structure that is separated from the holder 1131. With such a configuration, as will be described later, the assembly of the first camera actuator is easy. This can be accomplished. Alternatively, the second member 1131a may be formed integrally with the holder 1131. In the following, we will describe it as a separated structure.

[0098] The rotating part 1140 is connected to the tilting guide part 1141 and pressurizes the tilting guide part 1141. It includes a second magnetic material 1142 and a first magnetic material 1143 having opposite polarities.

[0099] The tilting guide section 1141 is connected to the mover 1130 and the first housing 1120 described above. It can be combined. Specifically, the tilting guide portion 1141 is connected to the holder 1131 and the first member 1126. It can be positioned between them. As a result, the tilting guide part 1141 moves the holder 1131 - It can be coupled with 1130 and the first housing 1120. However, contrary to the above, In this embodiment, the tilting guide portion 1141 is located between the first member 1126 and the holder 1131. It can be arranged as follows. Specifically, the tilting guide portion 1141 is the first member 1126 and the holder 11 It may be located between the 31st and the 4th anchorage ditch.

[0100] In the third direction (Z-axis direction), the second member 1131a, the first member 1126, and the tilting guide part 11 41 and holder 1131 may be arranged in that order. Also, the second magnetic material 1142 and the first magnetic material 1143 respectively are the first groove gr1 formed in the second member 1131a and the first member 112 It can be fixed to the second groove gr2 formed in 6. In this embodiment, the first groove gr1 and the second groove g r2 may be located in a different position from the first and second grooves described in the other embodiments described above. However, The first groove gr1 is located within the second member 1131a and moves integrally with the holder, and the second groove g r2 is located on the first member 1126 corresponding to the first groove gr1, and the first housing 1120 It combines with this. Therefore, this term will be used interchangeably in explanations.

[0101] Furthermore, the tilting guide section 1141 may be positioned adjacent to the optical axis. This allows, The actuator according to the embodiment allows for changes in the optical path in accordance with the first and second axis tilt described later. It can be done using the I Ching.

[0102] The tilting guide portion 1141 has a first projection portion that is spaced apart in the first direction (X-axis direction), It may include a second projection that is spaced apart in a second direction (Y-axis direction). The first and second protrusions can protrude in opposite directions. A more detailed explanation of this will follow later. .

[0103] Furthermore, as described above, the second magnetic material 1142 may be located within the second member 1131a. Furthermore, the first magnetic material 1143 may be located within the first member 1126.

[0104] The second magnetic material 1142 and the first magnetic material 1143 may have the same polarity as each other. The second magnetic material 1142 may be a magnet with an N pole, and the first magnetic material 1143 may have an N pole. It could be a magnet. Or, conversely, the second magnetic material 1142 is a magnet with a south pole. Therefore, the first magnetic material 1143 can be a magnet with a south pole.

[0105] For example, the first pole surface of the first magnetic material 1143 and the second magnetic material 114 facing the first pole surface The second pole surface of 2 may have the same polarity as the other pole surface.

[0106] The second magnetic material 1142 and the first magnetic material 1143 exert a repulsive force (r) between them due to the polarity described above. This configuration allows for the generation of an eplusive force. The repulsive force described above is due to the second member 1131a coupled to the second magnetic material 1142, or the holder 11 31 and the first member 1126 coupled to the first magnetic material 1143, or the first housing 1120 It can be added to. At this time, the repulsive force applied to the second member 1131a is connected to the second member 1131a. This can be transmitted to the joined holder 1131. This allows the second member 1131a and the first member The tilting guide portion 1141, positioned between 1126 and 1126, can be pressurized by a repulsive force. The repulsive force is caused by the tilting guide section 1141 moving between the holder 1131 and the first housing 1120 (or This configuration allows the X-axis to be maintained in position between the first member 1126). The position between the mover 1130 and the first housing 1120 is maintained even during tilt or Y-axis tilt. It can be held. Also, the tilting guide part consists of the first magnetic material 1143 and the second magnetic material 1142 Due to the repulsive force between them, the first member 1126 and the holder 1131 can be brought into close contact.

[0107] The first drive unit 1150 includes a drive magnet 1151, a drive coil 1152, and a Hall sensor. It includes part 1153, the first substrate part 1154, and the yoke part 1155. The details of this are as follows: More details will follow.

[0108] Figure 6a is a perspective view of the first housing of the first camera actuator according to an embodiment. Figure 6b is a perspective view from a different direction than Figure 6a, and Figure 6c shows the first camera actuator according to an embodiment. This is a front view of the first housing of the device.

That is, the first housing 1120 may be coupled with the first member 1126 to form an integral structure. Alternatively, the first housing 1120 may include the first member 1126.

[0110] The first housing side 1121 and the second housing side 1122 face each other. They can be arranged in this way. Also, the third housing side portion 1123 and the fourth housing side portion 1124 They can be arranged so that they face each other.

[0111] Then, the third housing side portion 1123 and the fourth housing side portion 1124 are the first housing It may be positioned between the side portion 1121 and the second housing side portion 1122.

[0112] The third housing side portion 1123 and the fourth housing side portion 1124 are connected to the first housing side portion 1121, the second housing side portion 1122 and the fourth housing side portion 1124. There fore, the third housing side portion 1123 may be a bottom surface of the first housing 1120 . And the fourth housing side portion 1124 may be an upper surface of the first housing 1120 .

[0113] And the first housing side portion 1121 may include a first housing hole 1121a . A first coil, which will be described later, may be disposed in the first housing hole 1121a.

[0114] Also, the second housing side portion 1122 may include a second housing hole 1122a. And a second coil 1152b, which will be described later, may be disposed in the second housing hole 1122a .

[0115] Also, the first housing side portion 1121 and the second housing side portion 1122 are the first housing 1120 may be side surfaces of.

[0116] The first coil and the second coil may be coupled to a first substrate portion. In an embodiment, the first coil and the second coi l are electrically connected to the first substrate portion to allow current to flow therethrough. Such current is an element of electromagnetic force that allows the second came ra actuator to tilt about the X-axis.

[0117] Also, the third housing side portion 1123 may include a third housing hole 1123a.

[0118] A third coil, which will be described later, may be disposed in the third housing hole 1123a. Also, the third The coil 1152c is electrically connected to the first substrate portion in contact with the first housing 1120 , and can be coupled to each other. Accordingly, the third coil is electrically connected to the first substrate portion, and receives current supply from the first substrate portion. Such a current is an electromagnetic force element that allows the second camera actuator to tilt about the Y-axis.

[0119] The first member 11 can be rested between the first housing side portion 1121 and the fourth housing side portion 1124 26. Therefore, the first member 1126 can be positioned on the third housing side portion 1123 . For example, the first member 1126 can be located on one side. Relative to the third direction, the first member 1126 and the holder can be positioned in sequence.

[0120] The fourth housing side portion 1124 is disposed between the first housing side portion 1121 and the second housing side portion 1 122, and can be in contact with the first housing side portion 1121, the second housing side portion 1122 and the third housing side portion 1123.

[0121] In addition, the fourth housing side portion 1124 can include a fourth housing hole 1124a. The fourth housing hole 1124a can be located above the optical member. Thereby, light can pass through the fourth housing hole 1124a and enter the optical member.

[0122] In addition, the first housing 1120 can include the accommodating portion 1125 formed by the first housing side portion to the fourth housing side portion 1124. The accommodating portion 1125 can have the first member 1126, the second member 1131a, and the mover 1130 positioned as components therein.

[0123] Furthermore, the first housing 1120 has a fifth housing side facing the first member 1126. , may further include. And the fifth housing side is the first housing side 1121 and the It is positioned between the 2 housing side portion 1122 and the 1 housing side portion 1121 and the 2 housing It can come into contact with the ng side portion 1122 and the third housing side portion 1123. Also, the fifth housing side The part includes an aperture region and provides a path for light reflected from the optical member 1132 to travel. It is possible. In addition, the fifth housing side portion includes projections or grooves, etc., adjacent to This configuration allows for easy coupling with other camera actuators. The fifth housing side provides an optical path and has an opening that provides the optical path. By improving the bonding force between the part and other components, the movement of the aperture due to separation, etc., is suppressed and the optical path is improved. Changes can be minimized.

[0124] Furthermore, as described above, the first member 1126 is connected to the first housing 1120, It may be a configuration included in housing 1120. That is, the first housing 1120 is , may include the first member 1126.

[0125] The first member 1126 may be placed in the first housing 1120. Or, the first part Material 1126 may be located within the first housing 1120.

[0126] The first member 1126 can be coupled to the first housing 1120. In this embodiment, the first Member 1126 is positioned between the first housing side portion 1121 and the second housing side portion 1122. It can be placed. Also, the first member 1126 is the third housing side portion 1123 and the fourth housing side It may be located between section 1124.

[0127] Further, the first member 1126 is located on the third housing side portion 1123, and can be in contact with the first housing side portion 1121 to the third housing side portion 1123.

[0128] Further, a first stopper 1121b may be provided on an inner side surface of the first housing side portion 1121. Further, a second stopper 1122b may be provided on an inner side surface of the second housing side portion 1122. .

[0129] The first stopper 1121b and the second stopper 1122b may be positioned symmetrically with reference to a first direction (X-axis direction). The first stopper 1121b and the second stopper 1122b may extend in the first direction (X-axis direction). With this configuration, even when the first member 1126 moves into the first housing 1120, the position of the first member 1126 can be maintained by the first stopper 1121b and the second stopper 1122b. In other words, the first stopper 1121b and the second stopper 1122b can maintain the first member 1126 positioned at one side within the first housing 1120.

[0130] Furthermore, the first stopper 1121b and the second stopper 1122b fix the position of the first member 1126, and fix the position of the tilt guide portion between the first member 1126 and the mover, thereby eliminating error-generating factors such as vibration. Accordingly, in the first camera actuator according to the embodiment, X-axis tilting and Y-axis tilting can be performed accurately.

[0131] Further, a separation distance L2 in a second direction (Y-axis direction) between the first stopper 1121b and the second stopper 1122b is smaller than a maximum length L1 of the first member 1126 in the second direction (Y-axis direction). This allows the first member 1126 to be separated from the first housing 1120. It can be assembled or inserted from the side and coupled with the first housing 1120.

[0132] Furthermore, the first member 1126 has a second projection groove PH2 into which the second projection of the tilting guide portion is secured. The second projection groove PH2 may be located on the inner surface 1126s1 of the first member 1126. Therefore, the first member 1126 has a projection (for example, a second projection) of the tilting guide portion that is in the fourth anchoring groove. The protruding part, which is positioned adjacent to the prism internally and serves as the reference axis for tilt, is the center of gravity of the mover 1130. Position it so that it is close to the tilt. This will allow the holder to tilt. The moment that moves the mover 1130 can be minimized. This will drive the coil Since the dynamic current consumption is also minimized, the power consumption of the camera actuator can be reduced.

[0133] Furthermore, the first member 1126 may include through holes 1126a and 1126b. There may be multiple holes, consisting of a first through-hole 1126a and a second through-hole 1126b.

[0134] The first through-hole 1126a and the second through-hole 1126b are connected to the first of the second member, which will be described later. The second extension can penetrate through each of them. Through this, the second member and the first member are joined. This is possible. In other words, the first housing and the mover can be connected to each other.

[0135] Between the first through hole 1126a and the second through hole 1126b, there is a second projection groove PH2 This configuration allows for the position between the tilting guide portion 1141 and the first member 1126. The bonding force is improved, and the tilt generated when the tilting guide part 1141 moves within the first housing The decrease in accuracy can be blocked.

[0136] Furthermore, a second groove gr2 may be located on the outer surface 1126S2 of the first member 1126. The first magnetic material can be fixed to groove gr2. And the outer surface 1126S of the first member 1126. 2 can face the inner surface of the second member or the member base. Furthermore, the second member The second magnetic material that has been secured and the first magnetic material of the first member 1126 face each other as described above. A repulsive force can be generated. As a result, the first member 1126 tilts due to the repulsive force. Because it pressurizes the holder inward, the mover is first A third housing side can be separated from the housing by a predetermined distance. Furthermore, the holder and A tilting guide section positioned between the uzing (for example, the first member) and the holder and housing It can be pressurized by the ring. In other words, the coupling force between the mover and the housing and tilting guide part It can be maintained.

[0137] Furthermore, if the first member 1126 is configured integrally with the first housing 1120, the first part The bonding force between material 1126 and the first housing 1120 is improved, and the camera actuator Reliability may be improved.

[0166] In the example, the third anchoring groove 1131S3a is either the first anchoring groove 1131S1a or the second anchoring groove 1 This configuration allows for a wider area than the 131S2a. This can be achieved by current control similar to that used for X-axis tilt.

[0167] The outer surface 1131S4 of the fourth holder is the outer surface 1131S1 of the first holder and the second holder. - Contacts the outer surface 1131S2, and the outer surface 1131S1 of the first holder and the outer surface 1 of the second holder It may be the outer surface extending from 131S2 in the first direction (X-axis direction). Also, the outer surface of the fourth holder Side 1131S4 is the outer side of the first holder 1131S1 and the outer side of the second holder 1131S It may be located between 2.

That is, the first region AR1 is This may correspond to the region located above the fourth anchoring groove 1131S4a. In this case, the first region AR 1 may not be a region within the fourth anchoring groove 1131S4a.

[0170] The first member 1126 may be located in the second region AR2. That is, the second region AR2 is The first member 1126 can be superimposed in the first direction (X-axis direction).

[0171] Furthermore, the second region AR2 is located on the outer surface 1131S4 of the fourth holder, similar to the first region. It can be placed there. That is, the second region AR2 is located at the top of the fourth anchoring groove 1131S4a. It can correspond to the domain.

Furthermore, the first member may include a second projection groove formed on its inner surface, as described above. The second projection can be secured to the second projection groove.

[0178] Furthermore, similar to the second magnetic material, the repulsive force generated by the first and second magnetic materials is applied to the first member. It may be added. Therefore, the first member and the second member are connected through a repulsive force between the first member and the holder 113 The tilting guide section positioned between 1 can be pressurized.

[0179] A tilting guide unit 1141 may be placed in the third region AR3. Furthermore, the first projection groove PH1 may be located in the fourth anchoring groove 1131S4a. Also, the first projection The first projection of the tilting guide portion 1141 can be accommodated in the groove PH1. The protrusion PR1 can come into contact with the first projection groove. The first projection groove PH1 has a maximum diameter equal to the first protrusion P This can accommodate the maximum diameter of R1. This also applies to the second projection groove and the second projection PR2. It can be used. That is, the maximum diameter of the second projection groove corresponds to the maximum diameter of the second projection PR2. This allows the second projection to come into contact with the second projection groove. First axis tilt can be easily performed using the first protrusion as a reference, and second axis tilt can be easily performed using the second protrusion as a reference. Therefore, the tilt radius can be improved.

[0180] Furthermore, in the embodiment, there may be multiple first projection grooves PH1.

The first-first projection groove PH1a and the first-second projection groove PH1b have the widest width. The values ​​can be identical to each other.

[0182] Multiple first projection grooves PH1 may have different numbers of inclined surfaces. For example, the first projection grooves PH1 may include the groove bottom and the inclined surface. In this case, the number of inclined surfaces of the multiple protruding grooves They can differ from one another. Furthermore, the width of the base surface in the protruding grooves can also vary.

[0183] For example, the first-first projection groove PH1a may include the first groove bottom surface LS1 and the first inclined surface CS1. The first and second projection grooves PH1b may include the second groove bottom surface LS2 and the second inclined surface CS2.

[0184] In this case, the widths of the first groove bottom surface LS1 and the second groove bottom surface LS2 may differ from each other. The width of the groove bottom surface LS1 can be made smaller than the width of the second groove bottom surface LS2.

[0185] Furthermore, the number of first inclined surfaces CS1 that are in contact with the bottom surface LS1 of the first groove is equal to the number of second inclined surfaces CS2. This can differ. For example, the number of first inclined surfaces CS1 may be greater than the number of second inclined surfaces CS2. It is possible.

[0186] This configuration allows for tolerances in the assembly of the first projection that is fixed to the first projection groove PH1. It can be easily supplemented. For example, the number of first inclined surfaces CS1 is equal to the number of second inclined surfaces CS2. Since there are more, the first protrusion comes into contact with the inclined surface with more, and the first-1 projection groove PH1a 1. The position of the protruding part can be maintained more accurately.

[0187] In contrast, in the first and second projection grooves PH1b, the number of inclined surfaces in contact with the first projection is Compared to the protruding groove PH1a of 1-1, it is smaller, and the position of the first protrusion can be easily adjusted. obtain.

It can be easily moved in the first direction (X-axis direction) while in contact with CS2. That is, In the first and second projection grooves PH1b, the first projection can be easily repositioned. Also, according to tolerances Ease of assembly can also be improved.

[0189] Furthermore, in this embodiment, the first region AR1, the second region AR2, and the third region AR3 are the The height may differ in one direction (X-axis direction). In the example, the first region AR1 is the second region AR2 Furthermore, the height can be made greater in the first direction (X-axis direction) than in the third region AR3. As a result, a step may be located between the first region AR1 and the second region AR2.

[0190] Furthermore, the second member 1131a may include the first groove gr1. That is, the member base portion 113 A first groove gr1 may be located on the inner surface of 1aa. And in the first groove gr1, as described above The second magnetic material can be fixed in place. Also, the first groove gr1 can be multiple depending on the number of second magnetic materials. It is possible that the first groove gr1 consists of a number of elements corresponding to the number of elements in the second magnetic material.

That is, the first extension portion 1131ab is from the member base portion 1131aa It can be extended toward the holder 1131. The same applies to the second extension 1131ac. Furthermore, the second extension 1131ac extends in the third direction from the edge of the member base portion 1131aa. It can be extended in the (Z-axis direction). In this embodiment, the first extension 1131ab and the second extension 1131 ac may be located at the edge of the member base portion 1131aa in the second direction (Y-axis direction).

That is, grooves (grooves) The ove) may be located between the first extension 1131ab and the second extension 1131ac. As a result, the first extension 1131ab and the second extension 1131ac are connected to the member base 1131 They can only be connected to each other by aa. With this configuration, the second member 1131a Repulsive force due to the second magnetic material fixed to the center of the member base portion 1131aa, particularly in the first groove gr1. You can receive it on a continuous basis.

[0195] Then, the second member 1131a is connected to the holder and moves during X-axis tilt and Y-axis tilt. In motion, the rigidity of the second member 1131a can become even greater than the rigidity of the first member. .

[0196] Furthermore, as described above, the first member according to the embodiment has an upper member and a lower member. This can increase rigidity. With this configuration, the difference in rigidity between the second member and the first member is reduced. A small amount is obtained. This allows the second member 1131a and the holder connected to the second member 1131a to be obtained. When both the first member 1131 and the second member 1131a are tilted along the X-axis or Y-axis, the second member 1131a The distance to the member becomes smaller, and it may come into contact with the first member. As a result, the first member... As described above, the improved rigidity allows it to perform its function as a stopper more easily. Yes, it is possible. In other words, the reliability of the camera actuator can be improved.

[0197] Furthermore, the difference in rigidity between the first and second members is reduced, and damage due to contact during tilting is reduced. Damage can be minimized; in other words, the reliability of the camera actuator can be improved.

[0198] Furthermore, the first extension 1131ab is in the second direction (Y-axis direction) relative to the second extension 1131ac. They can be separated to form a separation space. In such a separation space, the first member and the tilting guide part are securely positioned. It is possible for them to be attached. Furthermore, the second magnetic material and the first magnetic material may be located in the separation space.

[0199] Furthermore, the first extension 1131ab and the second extension 1131ac are in the third direction (Z-axis direction) The lengths may be the same. As a result, the bonding force and weight are well balanced, and the holes The tilt of the dial can be precisely controlled without tilting it to one side.

As described above, the end of the second protrusion PR2 is connected to the outer surface of the fourth holder and the first member 1126 It may be located between the two. That is, the second protrusion PR2 is at least partially located between the holder 113 It can be located in the opposite direction to the third direction (Z-axis direction) from 1. In other words, holder 1131 is At the end of the second projection PR2 (the part that contacts the second projection groove), a predetermined direction in the third direction (Z-axis direction) They can be separated by a distance.

[0260] Furthermore, the front surface 1131aes of the second member 1131a in the embodiment is the same as that of the second member 1126. It can be separated from the front surface 1126es. In particular, the front surface 11 of the second member 1131a according to the embodiment 31aes extends from the front surface 1126es of the second member 1126 toward the third direction (Z-axis direction) It may be positioned as follows. Alternatively, the front surface 1131aes of the second member 1131a according to the embodiment is the second part It may be located inside the front surface 1126es of material 1126. For this purpose, the first member 1126 is It may have an inwardly extended and folded structure. And the second member 1131a This is because a portion of the structure is located in the groove formed by the extension and bending of the first member 1126 described above. It can be placed there.

[0261] With this configuration, the second member 1131a is located inside the second member 1126. This improves space efficiency and enables miniaturization. Furthermore, it allows for electromagnetic force-driven (mover) Even if tilting or rotation of -1130 occurs, the second member 1131a is the same as the first member 1126. It does not protrude outwards, and contact with surrounding elements can be blocked. This improves reliability. It is possible to do so.

[0262] Furthermore, a predetermined separation space exists between the second magnetic material 1142 and the first magnetic material 1143. In other words, the second magnetic material 1142 and the first magnetic material 1143 have the same polarity and are mutually exclusive. It can counter them.

[0264] Referring to Figures 12a to 12c, in the first camera actuator according to the embodiment... Y-axis tilt may occur. That is, rotation in the first direction (X-axis direction) is performed to realize OIS. It is possible.

[0265] In this embodiment, the third magnet 1151c, which is located at the bottom of the holder 1131, is the third magnet Il 1152c forms an electromagnetic force, and mover 113 with the second direction (Y-axis direction) as the reference. 0 can be tilted or rotated.

[0266] Specifically, the repulsive force between the second magnetic material 1142 and the first magnetic material 1143 is applied to the second member 1131a. The signal is then transmitted to the first member 1126, and finally between the first member 1126 and the holder 1131. This can be transmitted to the tilting guide section 1141 that is positioned there. Therefore, the tilting guide section 1141 is The mover 1130 and the first housing 1120 can be pressurized by the repulsive force described above.

[0267] Furthermore, the second protrusion PR2 can be supported by the first member 1126. In this case, The tilting guide portion 1141 has a second projection PR2 that protrudes toward the first member 1126. Using as the reference axis (or axis of rotation), that is, rotating with respect to the second direction (Y-axis direction) It can be tilted. In other words, the tilting guide portion 1141 moves toward the first member 1126. Using the protruding second projection PR2 as the reference axis (or axis of rotation), rotate in the first direction (X-axis direction). It can be rotated or tilted.

[0268] For example, the third magnet 1151c is placed in the third mounting groove and is placed on the side of the third substrate. The first electromagnetic forces F1A and F1B between the third coil section 1152c cause the mover 113 The OIS is realized by rotating 0 in the X-axis direction by a first angle θ1 (X1->X1a). can.

[0269] Conversely, the third magnet 1151c positioned in the third mounting groove and the third substrate side are positioned on the side The first electromagnetic forces F1A and F1B between the third coil section 1152c are applied to the mover 11 Rotate 30 in the opposite direction of the X-axis by a first angle θ1 (X1->X1b) while performing OIS. It can be expressed.

[0270] The first angle θ1 can be between ±1° and ±3°, but is not limited to this range.

[0271] Furthermore, the center MC1 of the second magnetic material 1142 and the center MC2 of the first magnetic material 1143 are in the third direction They can be arranged in a line along the direction (Z-axis direction). That is, the center MC1 of the second magnetic material 1142 The center line TL1 connecting the center MC2 of the first magnetic material 1143 is in the third direction (Z-axis direction) It could be parallel to that.

[0272] Then, the second protrusion PR2 is bisected, and the bisector line TL2 corresponding to the third direction (Z-axis direction) is formed. It can be parallel to the center line TL1. In other words, the angle bisector TL2 is the second projection PR2 These lines can be lines that bisect a plane in one direction (the X-axis direction), and there can be multiple such lines.

[0273] In this example, such a bisector TL2 is separated from the center line TL1 in the first direction (X-axis direction). They can be positioned as follows. The bisector TL2 may be located above the center line TL1. This configuration increases the separation distance between the third coil 1152c or the third magnet 1151c. In addition, the holder can tilt more precisely on two axes. Furthermore, current is applied to the coil. If not added, the holder's position can be maintained in the same place.

[0274] More specifically, the central MC1 of the second magnetic material 1142 and the central MC2 of the first magnetic material 1143 Since it is separated from the bisector TL2 in the first direction (X-axis direction), the second magnetic material 1142 and the first The force between magnetic materials 1143 (for example, repulsive force) is measured from the first direction of the angle bisector TL2 corresponding to the optical axis. It can act by moving away in the direction (X-axis direction). And with this force, the mover Momentum occurs at -1130. However, the center MC1 of the second magnetic material 1142 and the first magnetic material When the center MC2 of body 1143 lies on the bisector TL2, the calibration proceeds. The problem is that the positions of the rotating guide and the second magnetic material 1142 are not maintained after tilting. A problem exists. That is, the camera actuator according to the embodiment is the second magnetic material 1142 The central MC1 and the central MC2 of the first magnetic material 1143 are not positioned on the bisector TL2. Therefore, the positions of the tilting guide and the second magnetic body 1142 are maintained even after tilting or rotation. It is possible.

[0275] In other embodiments, the central MC1 of the second magnetic material 1142 and the central MC2 of the first magnetic material 1143 are They can be arranged separated in the first direction (X-axis direction).

[0276] Furthermore, the center MC1 of the second magnetic material 1142 and the center MC2 of the first magnetic material 1143 are of the second order. It may not be located on the branch line TL2. For example, the center MC1 of the second magnetic material 1142 and The center MC2 of the first magnetic material 1143 may be located above the bisector TL2.

[0277] This increases the separation distance between the third coil 1152c or the third magnet 1151c. In addition, the holder can tilt more precisely on two axes. Furthermore, current is imprinted on the coil. If not added, the holder's position can be maintained in the same place.

[0278] Furthermore, the length of the second magnetic material 1142 and the first magnetic material 1143 in the first direction (X-axis direction) They can be different from each other.

[0279] In the embodiment, the second member 1131a is coupled to the mover 1130 and tilted together with the second The magnetic material 1142 can have a larger area than the first magnetic material 1143. Therefore, the length of the second magnetic material 1142 in the first direction (X-axis direction) is the same as that of the first magnetic material 1143. The length can be made larger than the length in the first direction (X-axis direction). Also, the second magnetic material 114 2 is the length in the second direction (Y-axis direction) of the first magnetic material 1143 in the second direction (Y-axis direction) It can be made larger than the length. Also, both ends of the second magnetic material 1142 extend in the third direction. The first magnetic material 1143 can be located within a hypothetical straight line.

[0280] With this configuration, when tilting or rotating, one side magnetic material (for example, the second magnetic material) Even when tilted, it is easy to prevent the generation of forces other than vertical forces due to the tilt. In other words, even if the second magnetic material is tilted up and down together with the mover 1130, the first magnetic material 1143 may not be subject to any force opposing the tilt (e.g., repulsive or attractive force). This may improve driving efficiency.

[0281] Figure 13a is a cross-sectional view from RR' in Figure 12a, and Figure 13b is the same as shown in Figure 13a. This is an example diagram illustrating the movement of a camera actuator.

[0282] Referring to Figures 13a and 13b, X-axis tilt can be performed, that is, towards the Y-axis. The mover 1130 can implement OIS while tilting or rotating.

[0283] In this embodiment, the first magnet 1151a and the second magnet are arranged in the holder 1131. Each of coils 1151b and 1152a and 2152b respectively exerts an electromagnetic force The tilting guide section 1141 and mover 113 are formed with reference to the first direction (X-axis direction). 0 can be tilted or rotated.

[0284] Specifically, the repulsive force between the second magnetic material 1142 and the first magnetic material 1143 is the first member 1126 and It is transmitted to holder 1131 and finally distributed between holder 1131 and first member 1126. It can be transmitted to the tilting guide section 1141 which is placed above. The mover 1130 and the first housing 1120 can be pressurized by the repulsive force described above.

[0285] Then, the 1-1 protrusion PR1a and the 1-2 protrusion PR1b are in the first direction (X-axis direction) The first projection groove is formed in the fourth attachment groove 1131S4a of the holder 1131, spaced apart in the direction of ( ). It can be supported by PH1. Also, in the embodiment, the tilting guide portion 1141 is supported by the holder 113 The first projection PR1 that protrudes toward 1 (for example toward the third direction) is the reference axis (or (where is the axis of rotation), that is, rotation or tilting with respect to the first direction (X-axis direction). It is possible.

[0286] For example, the first and second magnets 1151a and 1151b placed in the first anchoring groove and the first , the second electromagnetic between the first and second coil sections 1152a and 1152b arranged on the side of the second substrate Due to energy F2A and F2B, mover 1130 is rotated in the Y-axis direction by a second angle θ2 (Y1- >Y1a) can be realized while OIS. Also, the first anchoring groove is located , second magnets 1151a, 1151b and first, second magnets arranged on the sides of the first and second substrates Due to the second electromagnetic forces F2A and F2B between the two coil sections 1152a and 1152b, mover 1 By rotating 130 in the Y-axis direction by a second angle θ2 (Y1->Y1b), OIS is realized. This is possible. The second angle θ2 can be ±1° to 3°. However, it is not limited to this. There isn't one.

[0287] Here, the second electromagnetic forces F2A and F2B are different from those shown in the illustration, and are in the third direction or the third direction. It can be generated in three opposite directions. And an electromagnetic force is applied to the coil, but in this specification And the coil is coupled to a fixed housing, so the magnet and The explanation will be based on the premise that a holder connected to a magnet moves. And, electromagnetism The force is described in relation to the direction in which the magnet and holder move. For example, the first coil is When subjected to an electromagnetic force in the opposite direction to the third direction (Z-axis direction), the first magneto is affected by the electromagnetic force. One side of the holder 1131 adjacent to the net and the first magnet is in the third direction (Z-axis direction) It receives a force. And when the second coil receives an electromagnetic force in the third direction (Z-axis direction), the aforementioned The electromagnetic force affects the second magnet and the other side of the holder 1131 adjacent to the second magnet. It receives a force in the opposite direction to the third direction (Z-axis direction). As a result, holder 1131, As illustrated, it can move when subjected to force in the "F2A" direction. In the opposite case, the holder 1131 can move under the force in the direction of "F2B". Therefore, the second electromagnetic force F2A As described above, F2B is electromagnetically generated by the first and second coils and the first and second magnets. It responds to the force that causes the holder to move.

[0288] Thus, the second actuator according to the embodiment is a drive magnet in the holder and the first The electromagnetic force between the drive coils arranged in the housing causes the mover 1130 to move in the first direction ( By controlling rotation in the X-axis direction or a second direction (Y-axis direction), when realizing OIS, Minimizing the occurrence of decentering and tilt phenomena, achieving the best optics. It can provide specific characteristics. Also, as mentioned above, "Y-axis tilt" is in the first direction (X This means rotating or tilting in the axial direction, and "X-axis tilt" means rotating in the second direction (Y-axis direction). It means to rotate or tilt.

The first guide portion 210 is positioned so as to be adjacent to the second side wall of the base 20 It may include a second guide portion 220 positioned thereon. The first side wall and the second side wall of the base 20 are An internal storage space can be formed, and the units can be arranged facing each other with the storage space in between. Within the accommodation space formed through the first and second side walls of the base 20, there is a first guide Section 210 and the second guide section 220 may be arranged. Specifically, the first guide section 210 is located in front Within the storage space, it may be positioned adjacent to the inner surface of the first side wall of the base 20. Furthermore, the second guide portion 220 is located within the accommodating space, and is located on the second side wall of the base 20. It can be positioned adjacent to the inner surface of

[0335] The first guide portion 210 is the first lens assembly 110 and the base 20 It may be positioned between the first side wall and the wall.

[0336] The second guide portion 220 is the second lens assembly 120 and the base 20 It may be positioned between the first and second side walls of the base. The first and second side walls of the base face each other. They can be arranged in such a way.

[0337] According to the embodiment, a first guide section 210 and a second guide section are precisely numerically controlled within the base. When the lens assembly is driven with 220 coupled, friction torque is By reducing frictional resistance, the driving force during zooming is improved. This results in technical benefits such as reduced power consumption and improved control characteristics.

[0338] Therefore, according to the embodiment, friction torque is minimized during zooming. However, lens decentering and tilting, This prevents the phenomenon where the central axes of the lens group and the image sensor are not aligned, thus improving image quality. A combination of technical effects can significantly improve resolution.

[0339] In conventional technology, when guide rails are placed on the base itself, along the injection direction... Because a gradient occurs, dimensional control is difficult, and if injection is not performed correctly, friction torque There was a technical problem where the increased power led to a decrease in driving force.

[0340] On the other hand, according to the embodiment, the guide rail is not placed on the base itself, but separately from the base 20. The first guide section 210 and the second guide section 220 are formed and assembled separately. This has the special technical effect of preventing a gradient from forming along the injection direction. It plays.

[0341] The base 20 can be ejected in the Z-axis direction. In the prior art, the base has a rail. When constructed as a body, a gradient is created as the rail is ejected in the Z-axis direction, and the straightness of the rail There was a problem with the lines becoming crooked.

[0342] According to the embodiment, the first guide portion 210 and the second guide portion 220 are injected separately from the base 20. This significantly reduces the occurrence of gradients compared to conventional technologies, and enables precise injection. This is possible, and it provides a special technical effect that prevents the generation of gradients during injection.

[0343] In the embodiment, the first guide portion 210 and the second guide portion 220 are injected along the X axis, The length may be shorter than the base 20, in which case the first guide portion 210 and When rails 212 and 222 are placed on guide section 220, a gradient is generated during injection. This minimizes the risk and results in a technical effect where the straightness of the rails is less likely to curve.

[0344] Figure 24 shows the first guide section 210 and the second guide section in a camera actuator according to an embodiment. This is an enlarged perspective view of section 220.

[0346] For example, the first rail 212 of the first guide section 210 is connected to the first rail 212a The first guide portion 210 may include the first and second rails 212b. A first support portion 213 may be included between rail 212a and the first-to-second rails 212b.

[0347] According to the embodiment, by providing two rails per lens assembly, either Even if one rail bends, the other rail ensures the accuracy of the lens assembly's movement. The technical effects are what make it possible.

[0348] Furthermore, according to the embodiment, by providing two rails per lens assembly, Even if there is an issue (problem) regarding the frictional force of the ball, which will be explained later, with respect to either rail, The smooth rolling drive on the other rail allows for the movement of the lens assembly. This results in a technical effect that ensures sufficient driving force.

[0349] The first rail 212 can be connected from one side to the other side of the first guide portion 210.

[0350] The camera actuator and camera module including the same according to the embodiment are used during zooming. This causes problems such as lens decentering and tilting. The problem was resolved, and the alignment and spacing between multiple lens groups became well matched. This prevents changes in the field of view and out-of-focus situations, significantly improving image quality and resolution. The resulting technical effects are what make it work.

[0351] For example, according to the embodiment, the first guide portion 210 is connected to the first rail 212a and the first and second rails 212a By providing rail 212b, the first rail 212a and the first rail 2 12b guides the first lens assembly 110, thereby improving the accuracy of alignment. The technical effects are realized.

[0352] Furthermore, according to the embodiment, by providing two rails per lens assembly, later This allows for a wider spacing between the balls, thereby improving the driving force. This prevents interference with magnetic fields and prevents tilting when the lens assembly is stopped or moving. The technical effects are realized.

[0353] The first guide portion 210 extends in a lateral direction perpendicular to the direction in which the first rail 212 extends. The building may include a first guide projection 215.

[0354] The first guide projection 215 may include a first projection 214p. For example, the first projection 2 14p can include the first-1 projection 214p1 and the first-2 projection 214p2. .

[0355] Also, referring to Figure 24, in the embodiment, the second guide portion 220 is one or more It may include the second rail 222.

[0356] For example, the second rail 222 of the second guide section 220 is connected to the second-first rail 222a The second guide portion 220 may include the second rail 222b. The second guide portion 220 is the second rail A second support portion (not shown) may be included between rail 222a and the second rail 222b. ru.

[0357] The second rail 222 may be connected from one side of the second guide portion 220 to the cotton batting.

[0358] Furthermore, the second guide portion 220 is positioned perpendicular to the direction in which the second rail 222 extends. It may include a second guide projection 225 extending in the direction.

[0359] On the second guide projection 225 are the second-first projection 224p1 and the second-second projection 224 It may include a second projection 224p which includes p2.

[0360] The first-1 projection 214p1 and the first-2 projection 214p2 of the first guide portion 210 , the 2-1 projection 224p1 and the 2-2 projection 224p2 of the second guide portion 220 This can be coupled to the third lens assembly 130, which will be described later.

[0361] According to the embodiment, the first guide portion 210 is connected to the first-1 rail 212a and the first-2 rail By having 212b, the first rail 212a and the first rail 212b By guiding the first lens assembly 110, the accuracy of alignment can be improved. The technique is effective.

[0362] Furthermore, according to the embodiment, the second guide portion 220 is connected to the second-first rail 222a and the second-second rail By providing rail 222b, the second-first rail 222a and the second-second rail 222 By guiding the second lens assembly 120, b improves the accuracy of alignment. The technical effects are realized.

[0363] Furthermore, by providing two rails per lens assembly, either one of the rails Even if one rail bends, the other rail ensures accuracy thanks to a technical effect.

[0364] Furthermore, according to the embodiment, by providing two rails per lens assembly, later This allows for a wider spacing between the balls, thereby improving the driving force. This prevents interference with magnetic fields and prevents tilting when the lens assembly is stopped or moving. The technical effects are what make it possible.

[0365] Furthermore, according to the embodiment, by providing two rails per lens assembly, Even if there is an issue (problem) regarding the frictional force of the ball, which will be explained later, with respect to either rail, This technology ensures driving force by allowing smooth rolling propulsion on the other rail section. The effect is achieved.

[0366] Furthermore, according to the embodiment, the guide rail is not placed on the base itself, but is formed separately from the base 20. By comprising a first guide section 210 and a second guide section 220 that can be assembled, A special technique that prevents the occurrence of a gradient along the ejection direction due to the integrated structure of the guide rail and the sprayer. The technique is effective.

[0367] In conventional technology, when guide rails are placed on the base itself, along the injection direction... Because a gradient occurs, dimensional control is difficult, and if injection is not performed correctly, friction torque There was a technical problem where the increased power resulted in a decrease in driving force.

[0368] Next, Figure 25a shows the first re in the camera actuator according to the embodiment shown in Figure 23. Figure 25b is a perspective view of the lens assembly, and Figure 25b is a first lens assembly shown in Figure 25a. This is a perspective view with some components removed.

[0369] Referring to Figure 24, the embodiment shows the first moving along the first guide portion 210. 1. Lens assembly 110 and 2. Lens assembly that moves along the 2. guide portion 220 It may contain 120 units of 'nburi'.

[0370] Also, referring to Figure 25a, the first lens assembly 110 is arranged such that the first lens 113 is The first lens barrel 112a is placed, and the first drive unit housing where the first drive unit 116 is located It may include the first lens barrel 112a and the first drive unit housing 112b. The first housing may be a barrel or lens barrel shape. The drive unit 116 may be a magnet drive unit, but is not limited to this, in some cases. Therefore, coils can also be positioned.

[0371] Furthermore, the second lens assembly 120 includes a second lens (not shown) on which the second lens is positioned. A barrel (not shown) and a second drive unit housing (not shown) in which the second drive unit (not shown) is located. ) may include. The second lens barrel (not shown) and the second drive unit housing (not shown) are second The second housing may be a barrel or lens barrel shape. The second drive unit This could be a magnet drive unit, but is not limited to this, and in some cases a coil It can also be arranged in this way. In this case, the second lens assembly 120 is essentially the first lens It may have the same structure as the lens assembly 110, therefore a detailed explanation of it is omitted. I'll omit it.

[0372] The first drive unit 116 corresponds to the two first rails 212, and the second drive unit corresponds to the It can accommodate two second rails 222.

[0373] The embodiment involves using one or more balls to drive or move a lens assembly. This can be done. For example, in this embodiment, the first guide portion 210 and the first lens assembly 1 A first ball bearing 117 is positioned between 10 and the second guide portion 220 and the It may include a second ball bearing (not shown) positioned between the two lens assemblies 120.

[0374] For example, in this embodiment, the first ball bearing 117 is located on the upper side of the first drive unit housing 112b. One or more first ball bearings 117a are arranged, and the first drive unit housing It may include one or more first- and second ball bearings 117b located below 112b. .

[0375] In the embodiment, the first ball bearing 117a among the first ball bearings 117 is , moving along the first rail 212a, which is one of the first rails 212, Of the first ball bearings 117, the first and second ball bearings 117b are located on the first rail 212. It can move along the other rail, the first-second rail 212b.

[0376] The camera actuator and camera module including the same according to the embodiment are used during zooming. This solves the problems of lens decentering and tilt, The alignment between the multiple lens groups improves, and the field of view changes and focus shifts. This technology prevents issues such as misfires and significantly improves image quality and resolution. To play.

[0377] For example, according to one embodiment, the first guide portion comprises the first-1 rail and the first-2 rail. By providing this, the 1-1 rail and the 1-2 rail connect to the 1st lens assembly 110 By moving, the first lens assembly 110 moves, and the second lens assembly 12 This results in a technical effect that improves the alignment accuracy between the zero point and the optical axis.

[0378] Referring to Figure 25b, in the embodiment, the first lens assembly 110 is the It may include a first assembly groove 112b1 in which a ball bearing 117 is positioned. The ball assembly 120 includes a second assembly groove (not shown) in which the second ball is positioned. obtain.

[0379] The first assembly groove 112b1 of the first lens assembly 110 may be multiple. At this time, with respect to the optical axis direction, 2 of the plurality of first assembly grooves 112b1 The distance between the two first assembly grooves 112b1 is greater than the thickness of the first lens barrel 112a It can also be made longer.

[0380] In the embodiment, the first assembly groove 112b1 of the first lens assembly 110 The second assembly groove of the second lens assembly 120 may be V-shaped. (Not shown) may be V-shaped. The first assembly of the first lens assembly 110 The groove 112b1 can be V-shaped, U-shaped, or connected to the first ball bearing 117 at two or three points. It may be a contact shape. Also, the second lens assembly 120 and the second assembly The groove (not shown) can be V-shaped, U-shaped, or in contact with the first ball bearing 117 at two or three points. It can be a shape that comes into contact with something. Such various shapes make it easy to eliminate deviations due to tolerances. obtain.

[0381] Next, Figure 26 is an illustrative diagram of the drive mechanism in a camera actuator according to an embodiment.

[0382] Referring to Figure 26, in the camera actuator according to the embodiment, the magnet drive unit An interaction between a first drive unit 116 and a first coil unit 141b generates an electromagnetic force DEM. I will now explain this.

[0383] As shown in Figure 26, in the camera actuator according to the embodiment, the first drive unit 116 The magnetization method for the magnet may be a vertical magnetization method. For example, in the embodiment, The north pole 116N and south pole 116S of the coil are both positioned to face the first coil section 141b. It can be magnetized. Therefore, current flows from the first coil section 141b in the y-axis direction perpendicular to the plane of the paper. The north pole (116N) and south pole (116S) of the magnet are positioned to correspond to the region. Obtain. And in this embodiment, the first drive unit 116 is the fourth magnet or the first The second drive unit 126 corresponds to either the fourth magnet or the fifth magnet. It can correspond to either the other of the Gnet. And in this embodiment, the first drive unit to the fourth drive unit The moving part corresponds to the magnet and coil of the second drive unit described above.

[0384] Referring to Figure 26, in the embodiment, the x-axis is reversed from the N pole 116N of the first drive unit 116. A magnetic force DM is applied in the opposite direction (the direction of the magnetic force can be the positive or negative direction shown in the diagram). ), current DE flows in the y-axis direction from the first coil section 141b region corresponding to the N pole 116N. Then, in accordance with Fleming's left-hand rule, an electromagnetic force DEM acts in the z-axis direction.

[0385] Furthermore, in the embodiment, a magnetic force DM is applied from the S pole 116S of the first drive unit 116 in the x-axis direction. Then, from the first coil section 141b corresponding to the S pole 116S, electricity is discharged in the opposite direction to the y-axis perpendicular to the plane of the paper. When flow DE flows, an electromagnetic force DEM acts in the z-axis direction according to Fleming's left-hand rule. (The direction of the electromagnetic force can be either the positive or negative direction shown in the diagram.)

[0386] At this time, the third drive unit 141, including the first coil section 141b, is in a fixed state. The first lens assembly 110, which is a mover on which the first drive unit 116 is located, is a current-type Depending on the direction, the rail of the first guide section 210 is directed in a direction parallel to the z-axis by electromagnetic force DEM. It can be moved back and forth along the line. The electromagnetic force DEM is the current DE applied to the first coil section 141b. It can be controlled in proportion to this.

[0387] Similarly, in the camera actuator according to the embodiment, a second magnet (not shown) and a second An electromagnetic force DEM is generated between the two coil sections 142b, causing the second lens assembly 120 to move along the optical axis. It can move horizontally along the rail of the second guide section 220.

[0388] <First substrate> Figure 27a shows the first substrate, from the first direction, with the first coil portion removed according to the first embodiment, viewed obliquely. This is a visual view, and Figure 27b shows the first substrate with the first coil portion removed according to the first embodiment in the second direction. Figure 27c is a perspective view from the front, and shows the first substrate on which the first coil section according to the first embodiment is arranged. Figure 28a is a perspective view showing the first substrate according to the first embodiment, and Figure 28b Figure 28c is a plan view of the first substrate with the first coil section removed according to the first embodiment. This is a plan view of the first substrate on which the first coil section according to the embodiment is arranged.

[0389] The first substrate according to the first embodiment will be described below with reference to Figures 27a to 28c. We will proceed with this. The first substrate can correspond to the second substrate section described above.

[0390] Prior to describing the first substrate, let us explain the multiple lens assemblies involved in the implementation of AF or Zoom. It is driven by the electromagnetic force between the magnet and the coil, but the position information of the lens assembly To obtain this, a position-sensing sensor can be placed inside the coil winding. For example, The position sensing sensor may be a magnetic sensor capable of sensing changes in magnetic force. For example, The position sensing sensor may be a Hall sensor, but is not limited to one. However, In the following explanation, we will assume that the position sensing sensor is a Hall sensor.

[0391] The Hall sensor is positioned inside the coil winding, and the inside of the coil winding is the coil It can be hollow. The Hall sensor detects the change in magnetic flux of a magnet placed in the lens assembly. The Hall sensor detects this, allowing the position information of the lens assembly to be obtained.

[0392] However, conventionally, the driver IC that controls the movement of the lens assembly and the Hall sensor are They were each placed on separate circuit boards. And in such cases, the Hall sensor is actually By measuring the Hall resistance of the Hall sensor while it is installed, the Hall sensor We were able to test the implementation status. However, recently, the camera module has been slimmed down and To achieve accuracy and other high performance, the driver IC and Hall sensor are mounted together on a single circuit board. The Hall sensor mounted on the circuit board is connected to the aforementioned driver IC.

[0393] At this time, a large number of pads are formed on the substrate, but all of the pads are the same as the drive It is connected to the Iba IC. And the Hall sensor is connected to the driver IC. It is simply connected to the Hall sensor and is not directly linked to it.

[0394] Here, the Hall sensor is SMT (Surface Mount Technology) It is mounted on the first substrate 160 via (ogy), etc. At this time, the Hall sensor In the SMT process, short-circuit failures occur in approximately 3% to 4% of cases. However, on the aforementioned substrates... There is no pad connected to the Hall sensor, and therefore the actual Hall sensor There is a problem in that the mounting state cannot be tested. In other words, the mounting state of the Hall sensor is not the Hall sensor's mounting state. This is confirmed by measuring the resistance, but in order to confirm the mounting state of the Hall sensor, The test must be carried out via the pads connected to the driver IC. However, The pad is not directly connected to the Hall sensor, but rather to the Hall sensor via a driver IC. It is connected to the sensor, and therefore, direct testing of the Hall sensor is not possible. There is a problem.

[0395] Therefore, in the embodiment, a test is directly connected to the Hall sensor on the first substrate 160. A pad is formed to allow testing of the mounting state of the Hall sensor.

[0396] The first circuit board 160 is connected to a predetermined power supply unit (not shown), and the third drive unit 141 and the fourth drive unit Each of the parts 142 can be supplied with power. Specifically, the first board 160 is the third drive The moving part 141 may include the first coil part 141b. The first substrate 160 is the first Power can be supplied to the Ill section 141b. Also, the first board 160 is the fourth drive unit 1 42 may include the second coil portion 142b. And the first substrate 160 is the second coil Power can be supplied to section 142b. The first substrate 160 is a rigid printed circuit board. (Rigid PCB), Flexible PCB, Rigid Printed Circuit Board Circuit boards (Rigid Flexible PCBs), etc., wiring patterns that can be electrically connected It can include a circuit board with a line.

[0397] The first substrate 160 comprises a first substrate region 160a, a second substrate region 160b, and a third substrate region Includes 160c.

[0398] The first substrate region 160a may be located outside the first side wall of the base 20. The substrate region 160b may be located outside the second side wall of the base 20. Also, the third substrate region 160c can connect the first substrate region 160a and the second substrate region 160b. The third substrate region 160c may be located outside the bottom of the base 20.

[0399] A driver IC 161 may be placed on one side of the first substrate region 160a. 61 receives sensing information obtained from a gyro sensor (not shown), and the received sensing information By using the information, the magnitude of the current or voltage supplied to the first coil section 141b is controlled. This is possible. In addition, the driver IC161 controls the zoom magnification or the corresponding frame Based on the position information, the magnitude of the current or voltage supplied to the first coil section 141b It can control the gyro sensor (not shown). In addition, the driver IC161 can receive signals from the gyro sensor (not shown). The acquired sensing information is received, and the second coil section 142b uses the received sensing information to... The magnitude of the current or voltage supplied to it can be controlled. Also, driver IC161 Based on the zoom magnification or focus position information corresponding to the zoom magnification, the second carp The magnitude of the current or voltage supplied to section 142b can be controlled.

[0400] The first substrate region 160a contains electronic components 162, excluding the driver IC 161. The electronic component 162 may be a capacitor, but is not limited to one. For example, the electronic component 162 is the first coil portion 141b or the second coil portion 142 A memory that stores control information for controlling the magnitude of the current or voltage supplied to b. It is possible.

[0401] In the drawing, the driver IC 161 and electronic component 162 are located on the first substrate 160. Although it is stated that it will be arranged in one substrate region 160a, it is not limited to this. For example, the dry The IC161 and electronic component 162 are arranged in the second substrate region 160b of the first substrate 160. It is also possible to do this. For example, either the driver IC 161 or the electronic component 162. One is placed in the first substrate region 160a of the first substrate 160, and the other is placed in the first substrate region 160a of the first substrate 160 It can also be placed in the 2-substrate region 160b.

[0402] The first substrate region 160a of the first substrate 160 contains the first coil portion 1 of the third drive unit 141. 41b is placed.

[0403] Furthermore, a first Hall sensor 71 may be arranged in the inner region of the first coil portion 141b. In this embodiment, the inner region of the first coil portion 141b contains a plurality of first hoses. A light sensor may be arranged in the inner region of the first coil portion 141b in the direction of the optical axis. A first-first Hall sensor 71a and a first-second Hall sensor 71b are arranged, spaced apart from each other. This is possible. In other words, as the zoom magnification of camera modules has increased recently... Therefore, the stroke of the lens assembly has increased, and therefore only one Hall sensor However, accurately sensing the position of the lens assembly can be difficult. Therefore, in the embodiment... In order to accurately sense the position within the stroke range of the lens assembly, multiple Use a Hall sensor. However, the embodiments are not limited to this. For example, Note that the first Hall sensor 71 can be implemented as a single unit, while the other can be implemented as three or more units. In the following, the first Hall sensor 71 is the first Hall sensor 71a and We will explain this assuming that it consists of the first and second Hall sensors 71b.

[0404] On the other hand, the first substrate region 160a is connected to the first Hall sensor 71. A test pad 163 is positioned. The first test pad 163 may consist of multiple units. For example, the number of first test pads 163 is determined by the number of first Hall sensors 71. It is possible. That is, in the first substrate region 160a, two corresponding to one Hall sensor A first test pad may be placed. For example, the first Hall sensor 71 is placed in the first hole Includes sensor 71a and 1-2 Hall sensors 71b, and therefore the first test pack Model D163 may include four first test pads.

[0405] The four first test pads 163 are located in the first substrate region 160a of the first substrate 160. On one surface, it may be located outside the first Hall sensor 71. For example, the four 1. The test pad 163 is positioned at a certain distance from the first Hall sensor 71, It may be arranged to surround the outside of the first Hall sensor 71.

[0406] Preferably, the four first test pads 163 are on one side of the first substrate region 160a. Among these, it may be arranged in the region corresponding to the first coil portion 141b. For example, the four 1. Test pad 163 is located on one side of the first substrate region 160a, the first coil portion They may be positioned overlapping with 141b. Preferably, the four first test pads 163 is positioned to overlap with the direction perpendicular to the optical axis (for example, the x-axis direction in Figure 26). It is possible.

[0407] Therefore, at least a portion of one surface of the first coil portion 141b is the four Each test pad 163 can be positioned directly opposite the others. More on this later. I will explain in detail.

[0408] In other words, in order to test the mounting state of the first Hall sensor 71, the first substrate The four first test pads 163 must be exposed to the outside on 160. Then, after the test of the first Hall sensor 71 is completed, the first test pad 1 The exposed portion of 63 must be covered with a protective member. For example, the first test pack If component D163 is exposed to the outside and comes into contact with other components, a short circuit may occur. This could lead to reliability issues.

[0409] In this embodiment, the first coil portion 14 is placed on the first test pad 163. Ensure that 1b is positioned, that is, the exposed portion of the first test pad 163. This is covered by the first coil portion 141b, and therefore, the first coil portion 141b This prevents the first test pad 163 from coming into contact with other components. The first coil portion 141b is arranged to enclose a coil pattern and the coil pattern. It is composed of a protective member (or insulating member) and therefore the first coil portion 141b The problem that arises from the contact between the first test pad 163 and the first test pad 163 is to can.

[0410] Furthermore, the second substrate region 160b of the first substrate 160 is the second coil of the fourth drive unit 142 Section 142b is positioned.

[0411] Furthermore, a second Hall sensor 72 may be arranged in the inner region of the second coil portion 142b. In this embodiment, the inner region of the second coil portion 142b has a plurality of second hoses. A light sensor may be placed in the inner region of the second coil portion 142b in the direction of the optical axis. A second-first Hall sensor 72a and a second-second Hall sensor 72b are arranged, separated from each other. It is possible.

[0412] On the other hand, the second substrate region 160b is connected to the second Hall sensor 72. A test pad 164 is positioned. The second test pad 164 may consist of multiple units. For example, the number of second test pads 164 is determined by the number of second Hall sensors 72. It is possible that, in the second substrate region 160b, two Hall sensors correspond to one Hall sensor. A second test pad may be placed. For example, a second hole sensor 72 may be placed in the second hole Includes sensor 72a and 2-2 Hall sensor 72b, and accordingly the second test Pad 164 may include four second test pads.

[0413] The four second test pads 164 are located in the second substrate region 160b of the first substrate 160. On one side, it may be located outside the second Hall sensor 72. For example, the four The test pad 164 is positioned at a certain distance from the second Hall sensor 72. They may be arranged surrounding the outside of the second Hall sensor 72.

[0414] Preferably, the four second test pads 164 are on one side of the second substrate region 160b Among these, it may be arranged in the region corresponding to the second coil portion 142b. For example, the four The test pad 164 is located on one side of the second substrate region 160b, and the second coil portion They may be positioned overlapping with 142b. Preferably, the four second test pads 164 is positioned to overlap with the direction perpendicular to the optical axis (for example, the x-axis direction in Figure 26). It is possible that one surface of the second substrate region 160b is outside the second side wall of the base 20. It may be a side surface facing the other surface. And the second test pad 164 is the base 2 It is positioned in a direction facing the second side wall of 0, overlapping with the second coil portion 142b. It is possible.

[0415] Therefore, at least a portion of one surface of the second coil portion 142b is the four The two test pads 164 can be positioned directly opposite each other. See below for details. I will explain this in more detail later.

[0416] In other words, in order to test the mounting state of the second Hall sensor 72, the first substrate The four second test pads 164 must be exposed to the outside on 160. Then, after the test of the second Hall sensor 72 is completed, the second test pad 1 The exposed portion of 64 must be covered with a protective member. For example, the second test pack If component D164 is exposed to the outside and comes into contact with other components, a short circuit may occur. This could lead to reliability issues.

[0417] In this embodiment, the second coil portion 14 is placed on the second test pad 164. Ensure that 2b is positioned, that is, the exposed portion of the second test pad 164. This is covered by the second coil portion 142b, and therefore, the second coil portion 142b This prevents the second test pad 164 from coming into contact with other components. The second coil portion 142b is arranged to enclose the coil pattern and the coil pattern. It is composed of a protective member (or insulating member) and therefore the second coil portion 142b This solves the problem caused by contact between the second test pad 164 and the second test pad 164. Cut.

[0418] In the following, the first test pad 163 and the first coil section 14 on the first substrate 160 are described. I will now explain the arrangement and structure with 1b in detail.

[0419] The first substrate 160 includes an insulating portion. The insulating portion includes an insulating layer 160-1, which will be described below, and the first insulating portion It may include a protective layer 160-3 and a second protective layer 160-4.

[0420] Specifically, the first substrate 160 includes an insulating layer 160-1. The insulating layer 160-1 may be rigid, or it may be flexible. That's fine.

[0421] For example, the insulating layer 160-1 is made of soda-lime glass. or containing chemically strengthened or semi-strengthened glass such as aluminosilicate glass, or polyimide (Pol Polyethylene terephthalate (polyethylene te rephthalate, PET), propylene glycol (propylene g Reinforced or flexible plastics such as lycol, PPG, and polycarbonate (PC) It may contain, or may contain sapphire.

[0422] Furthermore, the insulating layer 160-1 may be partially rigid or flexible. This is also acceptable. Therefore, the first substrate 160 has a partially flat surface and a partially curved surface. It can bend. For example, the first substrate 160 has a partially random curvature. It can bend or flex while having a surface that contains random curvature. ru.

[0423] A circuit pattern may be placed on the insulating layer 160-1. The circuit pattern is dry The circuit pattern may include a first mounting pad (not shown) on which IC161 is mounted. The circuit pattern may include a second mounting pad (not shown) on which an electronic component 162 is mounted. It may include a first test pad 163 connected to the first Hall sensor 71. The turn connects the first Hall sensor 71 and the first test pad 163, or the It may include a connecting wire 160-2 that connects the 1 Hall sensor 71 and the driver IC 161. ru.

[0424] A first protective layer 160 is disposed on the insulating layer 160-1, covering the circuit pattern. -3 may be placed. The first protective layer 160-3 is placed on the insulating layer 160-1. Among the road patterns, the surface of the first test pad 163 may be exposed and arranged. Although not shown in the drawing, the first protective layer 160-3 is part of the circuit pattern. A coil pad (not shown) connected to the first coil portion 141b may be exposed and arranged. In this case, the first protective layer 160-3 may be solder resist.

[0425] A second protective layer 160-4 may be placed on the first protective layer 160-3. The protective layer 160-4 may be a coverlay. The second protective layer 160-4 is the insulating layer 1 The first test pad 163, positioned on 60-1, can be exposed.

[0426] In other words, the first protective layer 160-3 and the second protective layer 160-4 have the first test pack An opening 160-5 can be formed that exposes the surface of D 163. Through steps 0-5, the first test pad 163 may be exposed on one side of the first substrate 160. The aforementioned one-sided direction may be the direction facing the outer surface of the first side wall of the base 20. In other words, the opening 160-5 is the first opening region formed in the first protective layer 160-3 This may include a region and a second opening region formed in the second protective layer 160-4.

[0427] On the other hand, the first coil portion 141b may be placed on the second protective layer 160-4. At this time, at least a portion of the first coil portion 141b is the first protective layer 160-3 and It can overlap with the opening 160-5 formed in the second protective layer 160-4. The opening 160 formed in the first protective layer 160-3 and the second protective layer 160-4 -5 may be covered by the first coil portion 141b.

[0428] In other words, in the embodiment, with the first Hall sensor 71 mounted as described above... Using the first test pad 163 exposed through the opening 160-5, the first The resistance of the Hall sensor 71 can be measured to proceed with testing the mounting condition. Then, once the test of the mounting state of the first Hall sensor 71 is completed, the opening 1 The first coil portion 141b is placed on 60-5. That is, in this embodiment, The first coil portion 141b is used to cover the exposed portion of the first test pad 163. ru.

[0429] According to this, in the embodiment, an additional protection for the first test pad 163 is provided. A protective layer is unnecessary, and therefore, additional steps for forming a protective layer are not required. Therefore, the manufacturing process can be simplified, and the removal of the protective layer reduces manufacturing costs. It can be reduced. Also, in the embodiment, the first test pad 163 or this Since the protective layer does not need to be exposed to the outside, the effect of design improvement can be achieved. This allows for greater design flexibility.

[0430] Furthermore, in Figure 28a, the first test pad 163 and in the first substrate region 160a Although only the arrangement structure of the first coil section 141b has been shown, similarly, the second substrate area The second test pad 164 and the second coil section 142b may be positioned at 160b. .

[0431] On the other hand, referring to Figures 28b and 28c, on the insulating layer 160-1 of the first substrate 160 A connecting wire 160-2 is formed there. The connecting wire 160-2 is connected to the first Hall sensor 71 and the first test pad 163 can be connected. Also, the connecting wiring 160- 2 allows the first Hall sensor 71 and the driver IC 161 to be connected.

[0432] At this time, the first Hall sensor 71 is the first Hall sensor 71a, and the first It includes two Hall sensors 71b. And each of the Hall sensors 71a, 71b is , including multiple terminals.

[0433] In other words, the first Hall sensor 71a includes an input terminal and an output terminal. In the conventional configuration, the input terminal of the 1-1 Hall sensor 71a is connected to the driver IC 161. It contained only one terminal.

[0434] In contrast, the input terminal of the Hall sensor 71a of the embodiment is, The embodiment may include an input terminal (not shown) and input terminals 1-2 (not shown). The output terminals of the 1-1 Hall sensor 71a are the output terminals of the 1-1 (not shown) and It may include the first and second output terminals (not shown).

[0435] The connecting wiring 160-2 is connected to the input terminal 1-1 and the first test pad 16 The first connecting wire 160-21 connects to the first test pad 163-1 of the three. It may include. Therefore, in the embodiment, through the test pad 163-1 of the 1-1 This allows testing the state of the input terminal of the Hall sensor 71a described above.

[0436] Furthermore, the connecting wiring 160-2 is connected to the input terminals 1-2 and the driver IC 161 It may include a third connecting wire 160-23 that connects to and . Therefore, the driver IC 161 is A signal is input to the Hall sensor 71a of the 1-1 via the third connecting wiring 160-23. It is possible to exert power.

[0437] The connecting wiring 160-2 is connected to the output terminal of 1-1 and the first test pad 16 The second connecting wire 160-22 connects the first and second test pads 163-2 of the three. It may include. Therefore, in the embodiment, via the 1-2 test pads 163-2 This allows testing the state of the output terminal of the Hall sensor 71a described above.

[0438] Furthermore, the connecting wiring 160-2 connects the output terminals of the 1-2 and the driver IC 161 It may include a fourth connecting wire 160-24 that connects to and . Therefore, the driver IC 161, The output from the Hall sensor 71a of the 1-1 is transmitted via the fourth connecting wiring 160-24. It can receive signals.

[0439] Furthermore, the first and second Hall sensors 71b include input and output terminals. The input terminals of the 1st-2nd Hall sensor 71b are the input terminal of the 2nd-1 (not shown), and It may include input terminal 2-2 (not shown). Also, the first and second Hall sensors in the embodiment. The output terminals of 71b are the second-first output terminal (not shown) and the second-second output terminal (not shown). ) may include.

[0440] The connecting wiring 160-2 is connected to the input terminal of 2-1 and the first test pad 16 The fifth connecting wire 160-25 connects the first to third test pads 163-3 of the three. It may include. Therefore, in the embodiment, via the test pads 1-3 163-3 This allows testing the state of the input terminals of the first and second Hall sensors 71b. At that time, the 1-1 test pad 163-1 and the 1-3 test pad 163-3 These can be arranged diagonally opposite each other, with the first Hall sensor 71 in between. In this embodiment, the goal is to minimize mutual interference among the multiple first Hall sensors 71. It is possible.

[0441] Furthermore, the connecting wiring 160-2 is connected to the input terminal of 2-2 and the driver IC 161 It may include a seventh connecting wire 160-27 that connects to and . Therefore, the driver IC 161, A signal is input to the 1st and 2nd Hall sensors 71b via the 7th connecting wiring 160-27. It is possible to exert power.

[0442] The connecting wiring 160-2 is connected to the output terminal of 2-1 and the first test pad 16 The sixth connecting wire 160-26 connects the first to fourth test pads 163-4 of the three. It may include. Therefore, in the embodiment, via the test pads 1-4 163-4 This allows testing the state of the output terminals of the first and second Hall sensors 71b.

[0443] Furthermore, the connecting wiring 160-2 is connected to the output terminal of 2-2 and the driver IC 161 It may include an eighth connecting wire 160-28 that connects to and . Therefore, the driver IC 161, The output from the 1st and 2nd Hall sensors 71b is transmitted via the 8th connecting wiring 160-28. It is possible to receive the signal. Also, as shown in Figure 28c, the first in the embodiment The first coil section 141b is placed on the test pad 163, and therefore the first coil Through part 141b, the exposed surface of the first test pad 163 can be protected. I'll do that.

[0444] Figure 29a shows the first substrate, with the first coil portion removed according to the second embodiment, viewed obliquely from the first direction. This is a visual view, and Figure 29b shows the first substrate with the first coil portion removed according to the second embodiment in the second direction. Figure 29c is a perspective view from the same angle, and is a diagram showing the coupling of the first substrate and the base according to the second embodiment. Figure 29d shows the structure of the first substrate with the base bonded according to the second embodiment. ru.

[0445] Referring to Figures 29a to 29d, the first and second test pads in the second embodiment are On the first substrate 160, the first coil portion 141b and the second coil portion 142b are overla It can be placed in an area that does not require topping up.

[0446] In other words, the first test pad 163 and the second test pad 164 in the first embodiment are , overlapping with the first coil section 141b and the second coil section 142b on the first substrate 160 It was placed in the area.

[0447] In contrast, the first test pad 163a and the second test pad in the second embodiment 164a is spaced apart from the first coil portion 141b and the second coil portion 142b on the optical axis. It can be placed.

[0448] The first test pad 163a is the same as the 1-1 to 1-4 test pads 163-1a, 1 Includes 63-2a, 163-3a, and 163-4a. Test pads 1-1 to 1-4 Two of 163-1a, 163-2a, 163-3a, and 163-4a are from the 1st-1 Ho One is connected to the Hall sensor 71a, and the remaining two are connected to the first and second Hall sensors 71b. .

[0449] The second test pad 164a is the same as the 2-1 to 2-4 test pads 164-1a, 1 Includes 64-2a, 164-3a, and 164-4a. Test pads 2-1 through 2-4. Two of 164-1a, 164-2a, 164-3a, and 164-4a are from the 2-1 section. One is connected to the Hall sensor 72a, and the remaining two are connected to the second-to-second Hall sensors 72b. .

[0450] At this time, the first test pad 163a and the second test pad 164 in the second embodiment Another protective layer may be placed on top of a.

[0451] However, in the embodiment, the base 20 is used, and the first test pad 163a and 2. Ensure that the exposed surface of the test pad 164a can be protected.

[0452] That is, as shown in Figures 29c and 29d, the first test pad 163a and The first and second side walls of the base 20 are positioned on the exposed surface of the second test pad 164a. The first side wall and the second side wall are connected to the first test pad 163a and the second test pad. The exposed surface of the stop pad 164a (preferably the first protective layer 160-3 and the second protective layer 16 The base 20 is positioned to cover the opening 160-5) of 0-4. The outer surfaces of the first and second side walls are positioned in contact with the second protective layer 160-4, It can be positioned to cover the opening 160-5.

[0453] Therefore, in the second embodiment as well, no additional protective layer is required to fill the opening 160-5. That is the case.

[0454] In other words, in the first embodiment, the opening 160-5 is the first coil portion 141b and The coil portion 142b covers the base 20 on both sides. Ensure that it is covered by a wall.

[0455] On the other hand, the first Hall sensor 71 and the second Hall sensor 72 have the first coil section as described above. 141b and the second coil section 142b are located inside the windings, and the inside of the windings is hollow inside the coil. This is possible. The first Hall sensor 71 and the second Hall sensor 72 are arranged in the lens assembly. The Hall sensor detects the change in magnetic flux of the placed magnet, thereby determining the position of the lens assembly. You can obtain location information.

[0456] By the way, inside the first coil section 141b and the second coil section 142b is the first Hall sensor When 71 and the second Hall sensor 72 are in position, the first coil portion 141b and the second coil The height of section 142b determines the distance between the Hall sensor and the magnet.

[0457] However, conventional technology requires thrust to move the lens assembly. In order to secure such thrust, the height of the coil must be above a certain level.

[0458] However, when the height of the coil increases in this way, the increased height of the coil The distance between the Hall sensor and the magnet will increase. Therefore, the magnet's magnetic field Because the flux is interrupted, the Hall sensor placed inside the coil detects the magnetic field. There was a technical contradiction where the sensitivity of the bundle weakened. Conversely, when reducing the height of the coil, The electromagnetic force between the magnet and coil weakens, resulting in lower thrust for AF or Zoom drive. There was a problem to be solved.

[0459] Furthermore, a decrease in thrust or a weakening of the Hall sensor sensitivity both affect the camera control. This has led to issues with the accuracy of the camera module, such as the decentering and tilting. The tilt phenomenon can be triggered, directly impacting the safety and lives of users such as drivers and pedestrians. obtain.

[0460] Therefore, one of the technical challenges of the embodiment is to increase thrust while using the Hall sensor We provide a camera actuator and a camera module including the same that can simultaneously increase sensitivity. It's about trying.

[0461] Figure 30a is a perspective view showing the first substrate on which the coil section according to the third embodiment is arranged, and Figure 3 Figure 30b is a perspective view showing the first substrate with the coil portion removed according to the third embodiment, and Figure 30c is This is a cross-sectional view of the first substrate according to the third embodiment.

[0462] Prior to explaining that, the first lens assembly 110 in the embodiment is the first The second lens assembly 120 may include a drive unit 116 and a third drive unit 141, and the second lens assembly 120 may include a second drive unit 141. It may include a drive unit 126 and a fourth drive unit 142.

[0463] The first drive unit 116 and the second drive unit 126 may be magnet drive units, and the third The drive unit 141 and the fourth drive unit 142 may be coil drive units, but are not limited to this. No.

[0464] In the camera actuator according to the embodiment, the first lens assembly 110 The drive unit 116 may include a first magnet 116b and a first yoke 116a, and the third drive unit The moving part 141 may include a first coil part 141b and a third yoke 141a.

[0465] Furthermore, in the camera actuator according to the embodiment, the second lens assembly 120 The second drive unit 126 may include a second magnet 126b and a second yoke 126a, The fourth drive unit 142 may include a second coil unit 142b and a fourth yoke 142a.

[0466] Then, referring to Figures 30a to 30c, the first coil of the first substrate 160 In the respective regions where section 141b and the second coil section 142b are arranged, there is a fixing groove 160- 6 is formed. And the first coil portion 141b and the second coil portion 142 in the embodiment b is positioned in the aforementioned anchoring groove 160-6.

[0467] Therefore, in the embodiment, the first coil portion 14 is limited to the depth of the fixing groove 160-6. The positions of 1b and the second coil section 142b can be arranged so as to be away from the magnet. In this embodiment, the first magnet is positioned opposite the first coil portion 141b. Move the to 116b closer to the first Hall sensor 71 by the depth of the fixing groove 160-6. It can be placed in a specific location.

[0468] In other words, the first coil portion 141b and the first magnet 116b are constant relative to each other. They must be separated. In this example, the first substrate 160 is fixed. A groove 160-6 is formed, and the first coil portion 141b is placed in the fixing groove 160-6. Therefore, the first magnet 116b is positioned to the depth of the first ho It can be positioned to be close to the Lucerne 71. In other words, the embodiment is in comparison with the comparative example. The distance between the first Hall sensor 71 and the first magnet 116b is equal to the depth of groove 160-6. You can get closer.

[0469] Furthermore, in the embodiment, the second coil portion 142b is positioned opposite the second coil portion 142b. The magnet 126b is brought closer to the second Hall sensor 72 by the depth of the fixing groove 160-6. They can be arranged in such a way.

[0470] In other words, the second coil portion 142b and the second magnet 126b are constant relative to each other. They must be separated. In this example, the first substrate 160 is fixed. A groove 160-6 is formed, and the second coil portion 142b is placed in the fixing groove 160-6. Therefore, the second magnet 126b is positioned to the depth of the anchoring groove 160-6. It can be positioned so as to be close to the Lucerne 72. In other words, the example is in comparison to the comparative example. The distance between the second hole sensor 72 and the second magnet 126b is only the depth of the aforementioned anchoring groove 160-6. The distance between them can be reduced.

[0471] At this time, the adhesive groove 160-6 removes the second protective layer 160-4 on the first substrate 160. It may be a de-region.

[0472] In other words, in the first embodiment, the first coil section 141b and the second coil section 142b are, It was placed on top of protective layer 160-4.

[0473] In contrast, the first coil section 141b and the second coil section 142b in the second embodiment This can be placed on the first protective layer 160-3.

[0474] In other words, the second protective layer 160-4 is arranged to cover the entire surface of the first protective layer 160-3. It is not that the first coil portion 141b and the second coil portion 142b are arranged in the area It may include an open region that opens up the area (which corresponds to the aforementioned anchoring groove). And, The first coil portion 141b and the second coil portion 142b are connected to the second protective layer 160-4. It can be placed in the open area.

[0475] Figure 31 compares the separation distance between the Hall sensor and the magnet in the examples and comparative examples. This is a diagram for that purpose.

[0476] Figure 31(a) shows the arrangement structure of the drive unit in the comparative example, and Figure 31(b) is This diagram shows the arrangement structure of the drive unit in the embodiment.

[0477] Referring to Figure 31(a), in the comparative example, the first carp is placed on the first substrate 160-41. The section 160-42 and the Hall sensor 160-43 are arranged, respectively. The first magnet 160-44 is positioned at a distance of a from the coil section 160-42. At this time, the first coil section 160-42 and the first magnet 160-44 are separated by a first gap. They can be placed with a distance of DH1 between them.

[0478] Referring to Figure 31(b), in this embodiment, the first coil portion 1 is placed on the first substrate 160. 41b and the first Hall sensor 71 are positioned. At this time, the first substrate 160 has an anchoring groove. It includes 160-6. The first coil portion 141b is arranged in the fixing groove 160-6. It can be placed. And in the embodiment, the first coil portion 141b is separated by a distance a from the second coil portion 141b. A magnet 116b is positioned. In this embodiment, the first Hall sensor 7 1 and the first magnet 116b are only separated by a second interval DH2 which is smaller than the first interval DH1. They can be separated.

[0479] In other words, the separation distance between the first coil portion and the first magnet is different between the example and the comparative example. In the same case, in the example, the depth of the anchoring groove 160-6 is compared to the comparative example. The distance between the first Hall sensor 71 and the first magnet 116b can be reduced. Therefore, in the embodiment, the first Hall sensor 71 and the first magnet 116 As the distance between b and the sensor decreases, the position measurement sensitivity of the Hall sensor can be improved. This can improve reliability. In other words, the depth of the anchoring groove 160-6 is b In this case, the first interval DH1 is made larger than the second interval DH2 by the amount of b. It is possible.

[0480] Figure 32 shows the magnetic flux depending on the distance between the magnet and the Hall sensor in the example and comparative example. This is Magnet Flux data.

[0481] Referring to Figure 32, in this embodiment, the first magnet is located to the depth of the anchoring groove 160-6. The distance between it and the first Hall sensor is reduced.

[0482] For example, the second interval DH2 in the example is 400 μm or less, and therefore, in the comparative example... It can be secured in a length more than twice as short compared to the comparative example, and as a result, the first magnet The magnetic flux between 116b and the first Hall sensor 71 was increased to approximately 150 mT, compared to the comparative example. This is due to a unique technical effect that allows for a price increase of approximately three times.

[0483] Therefore, the camera actuator and camera module including the same according to the embodiment are This unique technical effect allows for both increased power and simultaneously enhanced sensitivity of the Hall sensor. ru.

[0484] Next, one of the technical challenges of the embodiment is that multiple AFs are required when implementing AF or Zoom. When the lens assembly is driven by the electromagnetic force between the magnet and the coil, each lens assembly A camera actuator that can prevent magnetic field interference between magnets attached to the hub. The objective is to provide data and camera modules that include it.

[0485] Furthermore, one of the technical challenges of the embodiment is preventing the magnet and yoke from coming apart. The aim is to provide a camera actuator and a camera module including the same that can perform the following actions. It is the matter.

[0486] Next, Figure 33 shows the oblique view of the first drive unit 116 in the camera actuator according to the embodiment. This is a visual representation.

[0487] Referring to Figure 33, in this embodiment, the first drive unit 116 is the first magnet 116b and The first yoke 116a includes a first support portion 116a1 and the first 1. A first side projection 11 extending from the support portion 116a1 to the side surface of the first magnet 116b. It may include 6a2.

[0488] The first side projection 116a2 may be arranged on both sides of the first magnet 116b. ru.

[0489] Furthermore, the first yoke 116a is in a different direction from the first side projection 116a2, for example It may include a first fixed projection 116a3 extending in the opposite direction.

[0490] The first fixed projection 116a3 is positioned approximately midway between the first support portion 116a1. It is possible, but not limited to this.

[0491] Similarly, in the embodiment, the second drive unit 126 is a second magnet 126b and a second yoke 12 The second yoke 126a includes 6a, and the second yoke 126a includes a second support portion (not shown) and a portion extending from the second support portion forward. This may include a second side projection extending to the side of the second magnet 126b.

That is, the camera actuator is moved by mover 3 The axis of rotation for rotation in the first direction and the axis of rotation for rotation in the second direction of 30 are relative to each other. Each plate is assigned to a different function. In this example, the mover -When the 330 rotates on two axes, the rotation axes are performed by different moving plates. This allows for more stable rotation and improves the accuracy of the rotation. This allows for ensuring the safety of the rotational drive.

[0554] At this time, the tilting guide portion 350 is in relation to the housing 310 and the mover 330. It can be placed in between.

[0555] The first tilting guide portion 351 and the second tilting guide portion 35 constitute the tilting guide portion 350. 2 may have the same shape and size as each other.
