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 drawings. The present invention is not limited to the following embodiments, and various modifications can be made without departing from 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 attached to the lens carrier 11 and the frame 13 to support the lens carrier 11; a frame 13 for accommodating the lens carrier 11 and the support plate spring 12; a driving unit for generating a driving force for moving the lens carrier 11 in a predetermined direction; and the 1 st and 2 nd cover plates 15 and 16 covering the side surfaces of the frame body 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 object is provided on the front side of the lens driving device 1, and an image pickup device (not shown) for receiving light from the object is provided on the rear side. The optical axis direction of the lens body is the front-back direction, also referred to as the X direction.
The lens carrier 11 is made of a resin material, and a 1 st side wall 11b, a 2 nd side wall 11c, a front wall 11d, and a rear wall 11e rise from the bottom 11a to form a box-like body having an upper opening. The lower opening may be open. The 1 st side wall 11b and the 2 nd side wall 11c are formed along the X direction, and respectively connect the front wall 11d and the rear wall 11 e. Light paths are formed in the front wall 11d and the rear wall 11 e. 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 an imaging object passes therethrough. The lens body is housed inside the box-shaped 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 used for mounting a magnet 140 constituting a part of the driving portion.
The frame 13 is made of a resin material, and a 3 rd side wall 13b, a 4 th side wall 13c, a front wall 13d, and a rear wall 13e rise from the bottom 13a to form a box-like body having an upper opening. The lower opening may be open. In which a lens carrier 11 is accommodated. The 3 rd side wall 13b and the 4 th side wall 13c are formed along the X direction, and respectively join the front wall 13d and the rear wall 13 e. Light paths are formed in the front wall 13d and the rear wall 13 e. In the present embodiment, the front wall 13d and the rear wall 13e are formed with through holes, respectively, so that light from the subject passes therethrough. The 1 st and 2 nd side walls 11b and 11c of the lens carrier 11 face the 3 rd and 4 th side walls 13b and 13c of the frame 13, respectively. As will be described later, the coil unit 14 is integrally formed on the 3 rd side wall 13b of the housing 13.
The support plate spring 12 has 2 1 st and 2 nd springs 12a and 12b, and supports the lens carrier 11 to be movable with respect to the frame 13. The 1 st and 2 nd springs 12a and 12b each have: a fixed-side mounting portion 12c mounted to the frame 13; a moving-side mounting part 12d mounted on the lens carrier 11; 2 elastic arm parts 12e connecting the fixed-side mounting part 12c and the moving-side mounting part 12 d; and 2 coupling portions 12f that couple the 2 elastic arm portions 12 e. The 2 elastic arm portions 12e and the 2 coupling portions 12f are formed in a ring shape, and light from the subject passes through the inside of the ring. The fixed-side mounting portion 12c of the 1 st spring 12a is mounted on the 4 th side wall 13c on the front wall 13d side of the frame 13, and the moving-side mounting portion 12d is mounted on the front wall 11d on 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 on the 4 th side wall 13c on the rear wall 13e side of the frame 13, and the moving-side mounting portion 12d is mounted on the rear wall 11e on the 1 st side wall 11b side of the lens carrier 11. In this way, the fixed-side mounting portion 12c and the moving-side mounting portion 12d are mounted on opposite sides with respect to the optical axis.
The drive 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 frame 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 becomes the N pole and the rear wall 11e side becomes the S pole. The coil 142 is wound around the normal direction of the facing surface of the magnet 140.
When a current flows through the coil 142, an electromagnetic force is generated in the coil 142 to move in the X direction. When an electromagnetic force is generated in the coil 142, a reaction force is generated on the magnet 140, and therefore the lens carrier 11 moves in the X direction together with the lens body, not shown, against the elastic force of the support plate spring 12.
On both sides of the frame 13, 1 st and 2 nd cover plates 15 and 16 are provided so as to cover the 3 rd side wall 13b and the 4 th side wall 13 c. These 1 st and 2 nd cover plates 15, 16 function as a protective cover and a shield cover.
Next, the coil unit 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 as viewed from the inside of the housing 13. As shown in fig. 5, the coil unit 14 includes a substrate 143, a coil 142 provided on the substrate 143, and at least a part of a frame 13 which is a resin molded body made of a resin material. The coil 142 and the substrate 143 are integrally molded with the resin molded body. The resin molded body is formed on the substrate 143 so as to cover the outer periphery of the coil 142, and the inner periphery of the resin molded body is aligned with the outer periphery of the coil 142. That is, the coil 142 is embedded in the 3 rd side wall 13b of the housing 13 without a gap. Therefore, as in the conventional art, it is not necessary to provide a gap between the resin molded body and the outer periphery of the coil 142 in consideration of dimensional errors between the coil 142 and the 3 rd side wall 13b of the housing 13 in order to avoid damage to the coil 142 due to the coil 142 hitting the resin molded body when the coil 142 is inserted into the opening of the resin molded body. Therefore, the outer peripheral diameter of the coil 142 can be increased by the gap, and the winding thickness of the coil 142 can be increased. Here, the winding thickness is a distance between the outer circumference and the inner circumference of the coil 142. That is, the number of turns of the coil 142 can be increased by effectively utilizing the size of the outer diameter of the coil 142. Further, the substrate 143 formed integrally can prevent the resin molded body from being strained after molding.
The coil unit 14 may be provided with the mounting member 141 inside the inner circumference of the coil 142. The substrate 143 may be a printed circuit board, a flexible printed circuit board, 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 electronic component for mounting. Further, the mounting member 141 may have a rectangular shape including a square shape, but may have another shape.
The thickness of the coil 142 (the thickness of the coil 142 in the winding axis direction) may be the same as or smaller than the thickness of the resin molded body. Accordingly, the coil 142 does not protrude from the inner surface of the 3 rd side wall 13b of the housing 13, and therefore the coil 142 is less likely to contact the magnet 140.
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 providing the coil 142 on the substrate 143; and integrally molding the resin molded body with the coil 142 and the substrate 143 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.
The step of providing the coil 142 on the substrate 143 may be a step of providing the coil 142 on the substrate 143 so as to surround the outer periphery of the mounting member 141 by providing the mounting member 141 on the substrate 143. The step of providing the coil 142 on the substrate 143 so as to surround the outer periphery of the mounting member 141 may be a step of providing the coil 142 on the substrate 143 so as to surround the outer periphery of the mounting member 141 by directly winding the coil 142 on the outer periphery of the mounting member 141.
Next, a description is given of an application example. 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 unit 14 includes a substrate 143, a coil 142 provided on the substrate 143, and a resin molded body made of a resin material, and the resin molded body is formed on the substrate 143 so as to cover the outer periphery of the coil 142, and the inner periphery of the resin molded body is aligned with the outer periphery of the coil 142. Therefore, the gap between the coil 142 and the resin molded body can be eliminated, and the outer peripheral diameter of the coil 142 can be increased by the gap, and the winding 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 of the outer diameter of the coil 142. Thus, a camera device in which an autofocus function or a shake correction function is improved can be obtained.
The camera device including the lens driving device 1 may be incorporated in an electronic apparatus. That is, the electronic device may be manufactured by incorporating the camera device manufactured by the above-described manufacturing method. Examples of the electronic device include a mobile terminal such as a smartphone, 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 configurations are not limited to the embodiments, and may be designed without departing from the scope of the present invention.
For example, although the driving unit is configured to provide the magnet 140 on the lens carrier 11 side and the coil unit 14 on the frame 13 side in the present embodiment, the driving unit may be configured to provide the coil unit 14 on the lens carrier 11 side and the magnet 140 on the frame 13 side. That is, the coil unit 14 can be attached to either the movable side (mover) side, which is the side where the lens carrier 11 moves, or the fixed side (stator) side, which is the side where the frame 13 is fixed. The resin molded body may be at least a part of the lens carrier 11.
In the present embodiment, 1 coil unit 14 is provided to move the lens carrier 11 in one direction, but a plurality of coil units 14 may be provided. Further, a plurality of coil units 14 may be arranged to move a movable member such as the lens carrier 11 in a plurality of directions.
