Detailed Description
Hereinafter, an embodiment of the lens driving device 1 according to the present invention will be described in detail with reference to the accompanying drawings. The present invention is not limited to the following embodiments, and various modifications are obviously possible within the scope of the present invention.
As shown in fig. 1 to 4, a lens driving device 1 according to an embodiment of the present invention includes: a lens carrier 11 for fixing a lens body not shown; a support plate spring 12 mounted on the lens carrier 11 and the frame 13 to support the lens carrier 11; a frame 13 accommodating the lens carrier 11 and supporting the leaf spring 12; a driving unit for generating a driving force for moving the lens carrier 11 in a predetermined direction; and 1 st and 2 nd cover plates 15, 16 covering the side surfaces of the frame 13. In the present embodiment, the subject side is referred to as the front side, and the opposite subject side is referred to as the rear side. In the present embodiment, a prism (not shown) for bending light from an imaging subject is provided on the front side of the lens driving device 1, and an imaging element (not shown) for receiving light from the imaging subject is provided on the rear side. The optical axis direction of the lens body is the front-rear direction, also referred to as the X direction.
The lens carrier 11 is made of a resin material, and the 1 st side wall 11b, the 2 nd side wall 11c, the front wall 11d, and the rear wall 11e stand up from the bottom 11a to form a box-like body open upward. The lower opening may be a closed type. The 1 st side wall 11b and the 2 nd side wall 11c are formed along the X direction, and connect the front wall 11d and the rear wall 11e, respectively. An optical path is formed in the front wall 11d and the rear wall 11e. In the present embodiment, a cutout is formed in the front wall 11d, and a through hole is formed in the rear wall 11e so that light from a subject passes through. The lens body is accommodated inside the box-like body of the lens carrier 11 from above after the lens driving device 1 is completed. In addition, a recess 11f is provided on the outer side surface of the 1 st side wall 11b of the lens carrier 11, the recess 11f being for mounting the magnet 140 constituting a part of the driving section.
The frame 13 is made of a resin material, and the 3 rd side wall 13b, the 4 th side wall 13c, the front wall 13d, and the rear wall 13e are formed as a box-like body with an upper opening, standing from the bottom 13 a. The lower opening may be a closed type. In which box-like body a lens carrier 11 is accommodated. The 3 rd side wall 13b and the 4 th side wall 13c are formed in the X direction, and connect the front wall 13d and the rear wall 13e, respectively. An optical path is formed in the front wall 13d and the rear wall 13e. In the present embodiment, through holes are formed in the front wall 13d and the rear wall 13e, respectively, so that light from a subject passes through. The 1 st side wall 11b and the 2 nd side wall 11c of the lens carrier 11 face the 3 rd side wall 13b and the 4 th side wall 13c of the frame 13, respectively. An opening 130 for mounting the coil block 14 is provided in the 3 rd side wall 13b of the housing 13.
The support plate spring 12 has 2 1 st and 2 nd springs 12a, 12b, and supports the lens carrier 11 so as to be movable with respect to the housing 13. The 1 st and 2 nd springs 12a, 12b have: a fixed-side mounting portion 12c mounted on the frame 13; a moving-side mounting portion 12d mounted on the lens carrier 11; 2 elastic arm portions 12e connecting the fixed side mounting portion 12c and the movable side mounting portion 12d; and 2 connecting portions 12f connecting the 2 elastic arm portions 12 e. The 2 elastic arm portions 12e and the 2 connecting portions 12f are formed in a ring shape, and light from the subject passes through the inside of the ring shape. The fixed-side mounting portion 12c of the 1 st spring 12a is mounted on the 4 th side wall 13c of the front wall 13d side of the housing 13, and the movable-side mounting portion 12d is mounted on the front wall 11d of the 1 st side wall 11b side of the lens carrier 11. The fixed-side mounting portion 12c of the 2 nd spring 12b is mounted to the 4 th side wall 13c of the rear wall 13e side of the housing 13, and the movable-side mounting portion 12d is mounted to the rear wall 11e of the 1 st side wall 11b side of the lens carrier 11. The fixed-side mounting portion 12c and the movable-side mounting portion 12d are thus mounted on opposite sides with the optical axis therebetween.
The driving unit includes: a magnet 140 provided on the 1 st side wall 11b of the lens carrier 11; and a coil block 14 provided on the 3 rd side wall 13b of the housing 13. The coil assembly 14 has a substrate 143 and a coil 142. The magnet 140 is disposed at a position facing the coil 142 of the coil block 14. The magnet 140 is magnetized such that, for example, the front wall 11d side of the surface facing the coil 142 is N-pole and the rear wall 11e side is S-pole. The coil 142 is wound around the normal direction of the opposing surface of the magnet 140.
When a current flows through the coil 142, an electromagnetic force is generated in the coil 142, which is intended to move in the X direction. When electromagnetic force is generated in the coil 142, a reaction force is generated to the magnet 140, and therefore, the lens carrier 11 moves in the X direction together with a lens body, not shown, against the elastic force of the supporting plate spring 12.
The 1 st and 2 nd cover plates 15 and 16 are provided on both sides of the frame 13 so as to cover the 3 rd and 4 th side walls 13b and 13 c. These 1 st and 2 nd cover plates 15, 16 function as protective covers and shielding covers.
Next, the coil block 14 will be described in detail with reference to fig. 5.
Fig. 5 is a view of the 3 rd side wall 13b of the housing 13 viewed from the inside of the housing 13, and the coil 142 of the coil block 14 and the mounting member 141 around which the coil 142 is wound are exposed from the opening 130 of the 3 rd side wall 13b of the housing 13. The coil block 14 includes a substrate 143, a mounting member 141 provided on the substrate 143, and a coil 142 provided on the substrate 143 so as to surround the periphery of the mounting member 141. The mounting member 141 is mounted on the substrate 143, and the substrate 143 of the coil block 14 is attached from the outer surface to the 3 rd side wall 13b of the housing 13 by adhesion or the like as shown in fig. 4. The mounting member 141 and the coil 142 are exposed from the opening 130 to the inside of the housing 13, and the coil 142 faces the magnet 140. The opening 130 may be a bottomed hole with a closed back side. The substrate 143 is a printed substrate on which the mounting member 141 is mounted, a flexible printed substrate, or the like. The mounting member 141 may be, for example, an IC incorporating a hall element, a driver IC, or the like, but is not limited thereto, and may be a general mounting electronic member. The mounting member 141 has a rectangular shape including a square, but other shapes may be used.
The coil 142 is formed of an electric wire whose surface is covered with an insulating material, and is directly wound around the mounting member 141 mounted on the substrate 143. As shown in fig. 5, the mounting member 141 includes 1 st and 2 nd corner portions C1 and C2 adjacent to each other, and 3 rd corner portion C3 facing the 1 st corner portion C1. At this time, the coil 142 is in contact with the 1 st to 3 rd corners C1 to C3. Therefore, as in the prior art, a gap is not required between the mounting member 141 and the inner periphery of the coil 142 in order to avoid damage to the coil 142 caused by the coil 142 hitting the mounting member 141 when the coil 142 is mounted on the outer periphery of the mounting member 141. Specifically, it is not necessary to expand the inner diameter of the coil 142 so as not to contact the 1 st to 3 rd corners C1 to C3 with the coil 142 at the same time. Thus, the inner peripheral diameter of the coil 142 can be reduced, and the coil thickness can be increased. Here, the thickness of the coil is a distance between the outer circumference and the inner circumference of the coil 142. I.e., the number of turns can be increased without increasing the outer peripheral diameter of the coil 142.
The 1 st to 3 rd corner portions C1 to C3 are preferably formed in a right triangle shape as shown in fig. 5 or an acute triangle shape to fix the coil 142 exactly. The coil 142 is preferably provided so as to be in close contact with the 1 st side surface S1 between the 1 st corner C1 and the 2 nd corner C2 of the mounting member 141 and the 2 nd side surface S2 which includes the 3 rd corner C3 and faces the 1 st side surface S1. In the example shown in fig. 5, the mounting member 141 has a rectangular shape, and the triangle formed by the 1 st to 3 rd corner portions C1 to C3 is a right triangle having the 2 nd corner portion C2 as a right angle. The coil 142 is formed in contact with the 1 st to 3 rd corner portions C1 to C3. The 2 nd side surface S2 is formed between the 3 rd corner C3 and the 4 th corner C4 facing the 2 nd corner C2, and the coil 142 is adhered to both side surfaces and also contacts the 4 th corner C4.
Further, as shown in fig. 6, the coil assembly 14 includes a resin molded body made of a resin material formed on the substrate 143 so as to cover the outer periphery of the coil 142. The resin molded body is integrally molded with the coil 142 and the substrate 143 so as to cover the outer periphery of the coil 142 and to match the outer periphery of the coil 142 with the inner periphery of the resin molded body. Therefore, as in the prior art, in order to avoid damage to the coil 142 caused by the coil 142 hitting the resin molded body when the coil 142 is fitted into the opening of the resin molded body, it is considered that a gap is provided between the resin molded body and the outer periphery of the coil 142 due to dimensional errors or the like of the coil 142 and the 3 rd side wall 13b of the housing 13. Therefore, the outer peripheral diameter of the coil 142 can be increased by the amount of the gap, and the coil thickness of the coil 142 can be increased. That is, the number of turns of the coil 142 can be increased by effectively utilizing the size given to the outer peripheral diameter of the coil 142. Further, the integrally molded substrate 143 can prevent the molded resin molded body from being strained.
The winding start end, which is the winding start end of the coil 142, can be disposed on the substrate 143 near the mounting member 141 and electrically connected thereto. The coil 142 can be wound further outside than the position where the winding start end is provided in a state where the mounting member 141 is mounted on the substrate 143. That is, at this time, the winding start end of the coil 142 is provided at a position overlapping the coil 142 as viewed in the winding axis direction of the coil 142. Thereby, the size of the coil block 14 can be further reduced. The winding terminal, which is the end on the winding side of the coil 142, is connected to the substrate 143 on the outside of the coil 142. The winding start end may be provided outside the coil 142.
Next, a method for manufacturing the lens driving device 1 according to the present embodiment will be described.
The method for manufacturing the lens driving device 1 includes: a step of disposing the mounting member 141 on the substrate 143; and a step of directly winding the coil 142 around the mounting member 141 and providing the coil on the substrate 143.
In order to manufacture the structure described later, a step of integrally molding the resin molded body, the coil 142, and the substrate 143 may be provided such that the resin molded body covers the outer periphery of the coil 142 and the outer periphery of the coil 142 coincides with the inner periphery of the resin molded body on the substrate 143.
Next, an application example will be described. The lens driving device 1 may be incorporated into a camera device. That is, the camera device may be manufactured by incorporating the lens driving device 1 manufactured by the above-described manufacturing method. The coil block 14 includes a substrate 143, a mounting member 141 provided on the substrate 143, and a coil 142 provided on the substrate 143 so as to surround the periphery of the mounting member 141, the mounting member 141 includes adjacent 1 st and 2 nd corner portions C1, C2 and a 3 rd corner portion C3 opposing the 1 st corner portion C1, and the coil 142 is in contact with the 1 st to 3 rd corner portions C1 to C3. Therefore, the inner circumference of the coil can be expanded to the inner side, and the coil thickness can be increased. As a result, the number of turns can be increased without increasing the outer peripheral diameter of the coil 142, and therefore, a camera device having an improved autofocus function or shake correction function can be obtained.
The camera device including the lens driving device 1 may be incorporated into an electronic apparatus. That is, the electronic device may be manufactured by incorporating a camera device manufactured by the above-described manufacturing method. Examples of the electronic device include a portable terminal such as a smart phone, a game machine, and a personal computer.
Although the embodiments of the present invention have been described in detail with reference to the drawings, the specific configuration is not limited to the embodiments, and includes designs and the like that do not depart from the scope of the present invention.
For example, in the present embodiment, the driving unit is configured to provide the magnet 140 on the lens carrier 11 side and the coil block 14 on the housing 13 side, but may be configured to provide the coil block 14 on the lens carrier 11 side and the magnet 140 on the housing 13 side. That is, the coil block 14 can be mounted on either one of a side that moves like the lens carrier 11, i.e., a mover (mover) side, or a side that is fixed like the frame 13, i.e., a stator (stator) side.
In the present embodiment, 1 coil block 14 is provided for moving the lens carrier 11 in one direction, but a plurality of coil blocks 14 may be provided. Further, a plurality of coil units 14 may be arranged to move the movable element such as the lens carrier 11 in a plurality of directions.
The coil 142 may be wound so as to be closely adhered to 3 or 4 side surfaces of the mounting member 141.
The coil block 14 is attached to the housing 13 by an adhesive or the like, but may be integrally molded with a resin molded body made of a resin material such as the housing 13 or the lens carrier 11. That is, the resin molded body is formed on the substrate 143 so as to cover the outer periphery of the coil 142. At this time, the outer periphery of the coil 142 and the inner side Zhou Yizhi of the resin molded body. The resin molded body may be at least a part of the lens carrier 11 or the frame 13 instead of the lens carrier 11 or the frame 13 itself. This can increase the outer peripheral diameter of the coil 142 and increase the coil thickness.
