[ Integrated Structure of lens Driving device ]
The description will be given taking the upper side of the paper surface as the front direction and the lower side as the rear direction in fig. 1. The front-rear direction is the optical axis direction of a lens (not shown), the front side is the imaging object (not shown), and the rear side is the imaging sensor (not shown).
In fig. 2 to 9, the upper and lower sides of the drawing are opposite to fig. 1, and the lower side on the paper surface in fig. 2 to 9 is the "front direction" in the optical axis direction, and the upper side is the "rear direction" in the optical axis direction.
First, the structure of the lens driving apparatus 1 of the present embodiment will be described. In fig. 1, the lens driving device 1 is provided with a lens holder 4, a base 13, a yoke 3, a magnet 9, a coil 8, a front spring 10, a rear spring 11, and a frame 2.
The lens holder 4 has a cylindrical shape, and a lens support portion 4a is formed on an inner peripheral side of the cylindrical shape. A lens (not shown in the figure) is supported by the lens supporting portion 4 a.
The base 13 has a plate shape, and a through hole through which light transmitted through the lens passes is provided at a center position of the base 13. The yoke 3 is mounted on the front side of the base 13.
The yoke 3 has an outer peripheral side wall 3a extending in the optical axis direction, an upper side wall 3b extending from an upper end of the outer peripheral side wall 3a to an inner peripheral side, and an inner peripheral side wall 3c extending rearward from an inner side of the upper side wall 3 b. The rear side of the outer peripheral side wall 3a is mounted on the front side of the base 13.
A magnet 9 for driving is fixed on the inner side of the outer peripheral side wall 3a, and the outer peripheral side surface 3a constitutes the yoke 3.
The coil 8 is annular in shape as viewed in the optical axis direction, and the winding portion 8a is attached to the outer periphery of the lens holder 4. In addition, 2 wires 8c are drawn out from the winding portion 8 a. The inner peripheral surface of the winding portion 8a is supported by a winding portion support member 5 of the lens holder 4, which will be described later. The outer peripheral surface of the winding portion 8a is located opposite to the inner peripheral surface of the magnet 9.
The front spring 10 includes an inner peripheral portion 10a, an outer peripheral portion 10b, and a plurality of arm portions 10c. The inner peripheral portion 10a is fixed to the front side of the lens holder 4. The outer peripheral portion 10b is provided radially outward from the inner peripheral portion 10a, and is fixed to a position between the frame 2 and the yoke 3. The arm portion 10c is connected to the inner peripheral portion 10a and the outer peripheral portion 10b, and is elastically deformable.
The rear spring 11 is divided into two parts, which have an inner peripheral side portion 11a, an outer peripheral side portion 11b, and a wrist portion 11c, respectively. The respective inner peripheral side portions 11a are fixed to the rear side of the lens holder 4. Starting from the inner peripheral portion 11a, the respective outer peripheral portions 11b are provided radially outward and fixed to the base 13. The arm portions 11c are connected to the inner peripheral portion 11a and the outer peripheral portion 11b, and are elastically deformable.

When power is supplied to the coil 8, a thrust (electromagnetic force) is generated by the magnetic flux of the magnet 9, and the lens holder 4 and a lens (not shown) supported by the lens holder 4 are also moved in the optical axis direction. Before the restoring force and the pushing force (electromagnetic force) of the front spring 10 and the rear spring 11 reach the equilibrium positions, the lens will move and related operations such as focusing the lens will be performed.
[ detailed Structure of lens Driving device ]
As shown in fig. 2 and 3, the lens holder 4 includes a winding portion support member 5 and a flange member 6. The winding part supporting member 5 is formed to protrude radially outward of the lens holder 4 from the outer peripheral surface 4b of the lens holder 4. The lens holder 4 is formed with 90 ° intervals in the circumferential direction, thereby forming 4 winding portion support members 5. The inner peripheral surface of the winding portion 8a of the coil 8 is supported by the outer peripheral surface of the winding portion support member 5.
The outer surface of the winding part supporting member 5 is planar. Further, the outer surface of the winding part supporting member 5 is recessed inward in the radial direction of the lens holder 4, so that an adhesive filling part 7 extending forward and backward in the optical axis direction is formed. The adhesive filling portion 7 is formed at a central position in the circumferential direction of the winding portion supporting member 5.
If the coil 8 is arranged, the winding portion 8a of the coil 8 is covered with the adhesive filling portion 7 from the outside in the radial direction. The adhesive will be filled into the space enclosed by the adhesive filling site 7 and the coil 8. The coil 8 is mounted on the outer periphery of the lens holder 4 by hardening of the adhesive.
On the rear side of the winding support part 5, the flange part 6 protrudes outward in the radial direction and extends in the circumferential direction of the lens holder 4. In addition, the flange portion 6 has a notch portion at a position where the wire winding support portion 5 is formed. The rear end of the winding portion 8a of the coil 8 is connected to the front side surface of the flange portion 6. A spring placement portion 6a is formed on the rear side surface of the flange portion 6, and is used for placing the inner peripheral portion 11a of the rear spring 11.
The notch portion is formed so as to face the winding portion support member 5, and the wire support portion 14 is formed in the circumferential end portion of the flange portion 6 where the notch portion is provided. The wire support portion 14 supports the wire 8c of the coil, and the wire 8c of the coil extends from the winding portion 8a of the coil 8. The wire supporting portions 14 are provided at two positions corresponding to the 2 wires 8c, but in the description of the present embodiment, only one of them will be described, and the other will be referred to for the description thereof.
The wire supporting portion 14 is provided on the outer side in the lens optical axis direction from the position where the winding portion 8a is mounted. The term "outside in the optical axis direction" means the front side in the optical axis direction, the rear side in the optical axis direction, and both ends of the front side and the rear side in the optical axis direction around the winding portion 8 a. In fig. 2 and 3, the wire supporting portion 14 is provided at the rear side in the optical axis direction from the position where the winding portion 8a is mounted. The wire supporting portion 14 is provided with a wire arrangement portion 15, a first wire accommodating portion 16, and a second wire accommodating portion 17.
The wire arrangement portion 15 is located at an intermediate position between the first wire accommodation portion 16 and the second wire accommodation portion 17, and the spring arrangement portion 6a is provided in an extended manner. The lead wire 8c is disposed at the lead wire disposition portion 15. The plane of the wire 8c on which the wire arrangement portion 15 is arranged faces the outside in the optical axis direction. I.e., to the rear side in the optical axis direction opposite to the position where the winding portion 8a is arranged. Although it is desirable that the position of the wire arrangement portion 15 in the optical axis direction is the same as the position of the spring arrangement portion 6a, the position may be the front side or the rear side. The lead wire arrangement portion 15 is provided with a recessed portion dedicated to the adhesive, and the recessed portion is recessed on the front side in the optical axis direction. When the wire 8c is connected to the rear spring by energization, an adhesive such as soldering may be injected into the concave portion.
A spring extension portion 19 is provided at a position further extending the spring arrangement portion 6a from the wire arrangement portion 15. A part of the inner peripheral portion 11a of the rear spring 11 is disposed at the spring extension portion 19. Therefore, the position of the spring extension portion 19 in the optical axis direction is desirably the same as the position of the spring arrangement portion 6a, but a slightly front position may be used.
A first wire accommodating portion 16 is provided at one edge portion of the flange portion 6 located between the wire arrangement portion 15 and the notch portion. The wire 8c drawn out from the winding portion 8a is accommodated in the first wire accommodating portion 16. The first wire accommodating portion 16 has a groove-like depressed portion 16a, and the depressed position of the depressed portion 16a is opposed to the wire arranging portion 15. The recessed portion 16a is formed in a groove shape from the boundary 20a with the wire arrangement portion 15 up to the notch portion. The groove-like bottom has an inclined portion 22a, and the inclined portion 22a is inclined from the boundary 20a of the wire arrangement portion 15, and the wire 8c can be laid along the inclined portion 22 a.
In addition, since the groove-like width of the concave portion 16a is larger than the diameter of the wire 8c, the wire 8c is easily guided inside the first wire accommodating portion 16. The groove-like width of the concave portion 16a may be the same as the width of the lead 8c. In this case, the wire 8c is supported inside the first wire accommodation portion 16. Combining the two ideas, widening the notch portion side and narrowing the boundary 20a side can be considered.
A second wire accommodating portion 17 is provided at an edge portion of the flange portion 6 between the wire arrangement portion 15 and the notch portion. Starting from the wire 8c placed at the wire arrangement portion 15, the wire 8c on the tip side is accommodated. The second wire accommodating portion 17 has a groove-like depressed portion 17a, and the depressed position of the depressed portion 17a is opposed to the wire arranging portion 15. The recessed portion 17a is formed in a groove shape from the boundary 20a with the wire arrangement portion 15 to the outer edge of the flange portion 6. The groove-like bottom has an inclined portion 22b, and the inclined portion 22b is inclined from the boundary 20b of the wire arrangement portion 15, and the wire 8c can be laid along the inclined portion 22 b.
The groove-like width of the depressed portion 17a is the same as the diameter of the lead wire 8c of the coil 8. Therefore, the wire 8c can be easily supported by the wire holder 14 by simply inserting the wire 8c into the concave portion 17a along the groove shape.
As shown in fig. 4 and 5, the coil 8 is mounted on such a lens holder 4. The rear end 8b of the winding portion 8a of the coil 8 is connected to the front side surface of the flange portion 6, and the inner peripheral surface of the winding portion 8a of the coil 8 is supported by the outer peripheral surface of the winding portion holder 5. The wire 8c pulled out from the rear end 8b of the winding portion 8a of the coil 8 is led from the notch portion of the flange portion 6 to a position where the wire 8c is further arranged on the wire arranging portion 15 at the groove-like recessed portion 16a of the first wire accommodating portion 16. In the boundary 20b between the wire arrangement portion 15 and the second wire accommodation portion 17, the wire 8c is bent and cut along the inclined portion 22b toward the front side in the optical axis direction.
The bent wire 8c is accommodated by fitting into the groove-like concave portion 17a of the second wire accommodating portion 17. The lead wire 8c is deformed by molding, and when placed in the lead wire placement portion 15, it is not moved until the connection with the spring 11 is made, and is further firmly supported by the lead wire holder 14 by being inserted from both sides by the groove shape of the concave portion 17 a.
Thus, the wire 8c of the coil 8 is supported by the wire support portion 14 of the lens holder 4 only by a simple wire 8c adjustment operation. As will be described later, when the lead wire 8c is placed on the lead wire placement portion 15, the connection operation is also very simple because the current is applied to the spring 11 to connect the same.
Next, as shown in fig. 6 and 7, the rear spring 11 is placed on the spring placement portion 6a, and then fixed.
An abutment portion is disposed in the inner peripheral portion 11a of the rear spring 11, and abuts against the wire 8c supported by the wire support portion 14. In fig. 6 and 7, the open end of the opening portion 11d is an adjacent portion.
The opening portion 11d accommodates the wire 8c placed in the wire arrangement portion 15. The opening 11d serves as a through hole. When the rear spring 11 is attached to the lens holder 4, the opening end of the opening 11d does not interfere with the lead wire 8c, and the rear spring 11 is attached to the lens holder and then set to a predetermined size at a position adjacent to the lead wire 8c. Therefore, the wire 8c does not move when placed in the wire placement portion 15. The lead wire 8c is exposed from the opening 11 d.
The position of the spring extension portion 19 in the optical axis direction is the same as the position of the spring placement portion 6a, and since the position is slightly behind, the inner peripheral portion 11a does not undergo the shaping deformation in the optical axis direction. The position of the wire arrangement portion 15 in the optical axis direction is not the same as the position of the spring arrangement portion 6a, and may be set at a position where connection is easy even if electricity is supplied. That is, at least the wire 8c supported by the wire support portion 14 is expected to be joined to the adjacent portion (the opening end of the opening portion 11 d) as viewed in the in-plane direction of the rear spring 11.
Next, as shown in fig. 8 and 9, the wire 8c of the coil 8 is connected to the inner peripheral portion 11a of the rear spring 11 by energization. Specifically, the open end of the opening 11d is bonded to the wire 8c accommodated in the opening 11d by a conductive adhesive such as solder paste 21. Since the open end abuts against the wire 8c and is positioned, it can be easily engaged. In addition, an adhesive such as solder paste 21 is injected into the adhesive-dedicated depressed portion 18, sandwiched from the front side and the rear side in the optical axis direction, and the wire 8c and the open end can be firmly joined.
As described above, in the present embodiment, there is no need to finish the wires of the coil again, and there is no need to wind up the tip end portions of the coil wires provided on the lens holder, so that the lens driving device can be easily manufactured.
[ implementation of Camera device and electronic device ]
By a simple wire 8c finishing operation, the object, i.e. the wire 8c of the coil 8 of the above-described lens driving device 1, can be supported by the wire support part 14 of the lens holder 4. Therefore, the lens driving device 1 does not need to be subjected to the following operation, that is, the coil wire is not required to be subjected to the finishing twice, and the front end portion of the coil wire which is provided on the lens holder and is convex does not need to be rolled up. Thus, the lens driving apparatus is easy to manufacture.
Therefore, in the present embodiment, the camera device and the electronic apparatus to which the lens driving device 1 is applied do not need to rearrange the coil wire, nor do they need to roll up the tip end portion of the coil wire which is provided on the lens holder and which is convex. It is therefore easy to manufacture the camera device and the electronic apparatus provided with the lens driving device 1.
While the preferred embodiments of the present utility model have been described above with reference to the accompanying drawings, the present utility model is not limited to these embodiments, and various modifications can be made while grasping the technology according to the description of the scope of the patent application.
For example, the winding support portion 5 may protrude from the outer peripheral surface 4b of the lens holder 4, but may not protrude. In addition, although the wire support portion 14 is formed as part of the flange portion 6, it does not hinder the possibility of being formed as a separate item. The wire supporting portion 14 may also be provided at a position other than the outer peripheral surface 4b of the lens holder 4. The wire support portion 14 is provided at the rear side in the optical axis direction from the position where the winding portion 8a is mounted, but the wire support portion 14 may be provided at the front side in the optical axis direction. And may be provided at both front and rear positions in the optical axis direction.
In addition, although the wound article tends to be mounted on the lens holder 4 by the coil, it may be directly wound on the lens holder 4 and mounted. In order to position the winding axis of the coil 8 in the radial direction, the lens holder 4 may be attached thereto.
The spring arrangement portion 6a is provided at the flange portion 6, but may be provided at the flange portion 6. The front and back are exchanged, and the front spring can be connected with the front spring by electrifying. Although the opening portion 11d is described as a through hole, a notch-like shape may be employed. Alternatively, a single spring end may be abutted against the wire 8c in the form of an abutment. Further, the electrical current may be supplied to connect a conductor other than the wire harness-shaped spring to a plate spring other than an FPC (flexible printed circuit board).
