New Description·· 【New Technology Fields】, Paste «About the lens actuator with a line preload function. [Prior Art] In the past years, the trend of handheld H-equipped image capture modules has become more and more popular. Looking forward to the market demand for better performance and smaller size for handheld devices, the image capture module is facing higher quality. The dual requirements for miniaturization are aimed at improving the image quality. On the one hand, it is to improve the quality of the pixel. The market trend of the handheld device image capture module is gradually increased from VGA# level 3Q, and millions to 2 million. Ten thousand, three million alizarins, even toward higher levels of four million, five million alizarin development. In addition to the improvement of the element, the sharpness of the image is also more concerned, so the handheld device image capture module is also developed by the fixed focus image capturing function toward the camera-like optical autofocus function or even the optical zoom function. The operation principle of the optical autofocus function is to appropriately move the lens in the image capturing module according to the different distances of the image capturing objects, so that the optical image of the image capturing object can be accurately focused on the image sensor, Produce clear images. At present, it is generally more common to drive the lens in the image capturing module. The actuation modes are stepper motor actuation, piezoelectric actuation, and voice coil motor (VCM) actuation. Generally, the mechanism of the voice coil motor is mainly constructed by placing a coil in a magnetic circuit including a permanent magnet. According to Fleming's left-hand rule, when the coil M320089 is electrically conductive, it will interact with the permanent magnet to move the carrier of the permanent magnet, thereby driving the lens bearing carriage fixed on the carrier, and by adjusting The current flowing through the coil reaches the purpose of optical zooming and focusing. However, when the voice coil motor drives the lens to move back and forth to achieve the purpose of optical zooming and focusing, the gap between the moving parts of the image capturing module and the fixing member often causes a free yaw angle when the lens moves. Too large, and the Φ image quality is reduced. Therefore, the use of a voice coil motor for optical zooming and focusing purposes requires a high-precision positioning function, and also requires high precision on the relative yaw of the fixed shaft and the optical axis to conform to the optical image. A voice coil motor 3 is mentioned in the "voice coil motor device" of the Republic of China Patent Publication No. 200525859. As shown in the first figure, the voice coil motor 3 includes a carriage 31, a magnetic circuit member 32, a coil 33, A plurality of guide steel shafts 341, 342 and a base 35. The carriage 31 is rigidly coupled to the magnetic circuit member 32, and the coil 33 and the plurality of guide steel shafts 341, 342 are fixed to the base 35, respectively. Wherein, the magnetic circuit member 32 provides a magnetic flux leakage line 37 through the gap 36 and magnetically interlinks with the plurality of guide steel shafts 341, 342 to generate magnetic pre-pressures 381, 382. The combined torque formed by the magnetic pre-pressures 381, 382 can eliminate the gap between the moving parts and the fixed contact surfaces 311, 312, so that the sliding seat 31 can be moved back and forth to obtain low friction, no free yaw, and high precision. The result of the exercise. > ^ * However, the aforementioned voice coil motor 3 is required to cause the yoke yoke to guide the leakage magnetic field 37 * . * to the outer edge and the plurality of guide steel shafts 341, 342 to achieve magnetic preloading effect. However, the configuration of the yoke will affect the difficulty of manufacturing. When it is the same as M320089, it also limits the configuration of other transitions. It also has its bottleneck in miniaturization. [New content] 'The main purpose of #ΐίΓΓ is to provide a kind of line pre- Pressure function = actuating device.

With the first picture of s, please refer to the third picture, which is the 3 3 corrective picture of the second picture of the creation. The hollow magnet group % is composed of a first hollow magnet mo, a young magnet, a hollow magnet 261, and a hollow magnetic conductive sheet 262 joined between the first and second hollow magnets 260, 261. The first and second hollow magnets 260, 261 are oppositely coupled to opposite sides of the hollow magnetic permeable sheet 262 with the same magnetic poles. The hollow magnetic conductive sheet 262 absorbs the magnetic lines φ ΐ and φ 2 emitted by the first and second hollow magnets 260 and 261, and causes the magnetic lines Φ1 and Φ2 to pass through the air-core coil 25, and the hollow M320089 coil 25 The electromagnetic fields generated after the conduction interact to generate an electromagnetic thrust to actuate the movable member. In other words, "Because the first hollow magnet 260 and the second hollow magnet 261 are magnetically bonded to the hollow magnetic conductive sheet 262 with the same polarity, the magnetic flux lines Φ1, Φ2 emitted will form a repulsive action without affecting each other, and at the same time, the magnetic force The lines Φ1 and Φ2 are absorbed by the hollow magnetic conductive sheet 262. The magnetic lines Φ1 and Φ2 are separated from the upper surface of the N pole of the first hollow magnet 260 and the upper surface of the N pole of the second middle φ hollow magnet 261 via the hollow The magnetic guide piece 262 guides and turns to the air gap formed by the slidable gap, and the magnetic lines Φ1, Φ2 pass through the air gap and pass through the air-core coil 25, and then return to the upper surface of the S-pole and the second hollow of the first hollow magnet 260, respectively. The lower surface of the S pole of the magnet 261 forms a closed magnetic circuit. When the magnetic lines Φ1 and Φ2 pass through the air-core coil 25, they interact with the electromagnetic field generated by the conduction of the air-core coil 25, thereby generating electromagnetic thrust. The magnetic piece 262 stores and concentrates the magnetic lines Φ1 and Φ2 radiated from the two hollow magnets 260 and 261 _, and guides the magnetic lines Φ1 and Φ2 collected and concentrated to effectively pass through the hollow line. 25, the magnetic lines Φ1, Φ2 emitted by the two hollow magnets 260, 261 do not cause bubble leakage, and the efficiency i also obtains sufficient actuation force to drive the lens to move. At the same time, by the first hollow magnet > 260 and the second The hollow magnet 261 ~ is magnetically coupled to the hollow magnetic conductive sheet 262 with the same polarity, so that the magnetic fluxes Φ1, Φ2 t ^ emitted by the first hollow magnet 260 and the second hollow magnet 261 form a repulsive action without causing magnetic cross-linking. Acting, causing the influence of the magnetic force lines Φ. 11 M320089 With the second figure, please refer to the fourth figure, which is a schematic structural view of the lens actuating device of the second embodiment of the present invention. The same elements of the device 2' are denoted by the same reference numerals as the lens actuators f 2 of the first embodiment. The principle of action of the magnetic circuit and the circuit of the second embodiment and the first embodiment are the same. By comparison, the main difference is that the fixing seat 23 of the second embodiment is provided with at least the open type E-hole 232 instead of the closed type perforation #234 of the first embodiment. When the closed perforation 234 is assembled, the use of the closed perforation 234 as the connection point of the linear elastic member 27 on the fixing seat 23 during the threading step must first connect the end of the linear elastic member 27 in assembly. In the slot jack of the lens bearing slide, the other end is passed through the closed perforation 234 and fixedly attached to the fixing base 23. This step of threading makes the assembly speed slower. In the second embodiment, the open chute hole 232 is used as the connecting elastic part of the linear elastic member 27 on the fixing base 23. The staff only needs to connect the end of the linear elastic member 27 to And the other end is connected to the fixed hole 23 and fixedly connected to the fixing seat 23, and the ^May type greatly solves the assembly. The speed, which in turn speeds up production. In the second embodiment, the cross-sectional view shown in the fifth embodiment is the same as the third embodiment in the first embodiment. Wherein the hollow magnet grade ^, the second first hollow magnet 260 is joined to a hollow guide piece 262. Therefore, the hollow magnetic conductive sheet 262 absorbs the magnetic line Φ1 emitted by the first hollow, and causes the magnetic line Φ1 to pass through the air, and 60 ΠΣ?! 12 M320089 25, and is electrically conductive with the air-core coil 25. The electromagnetic field interaction is then generated to generate an electromagnetic thrust to actuate the movable member. In other words, the second embodiment takes the second hollow magnet 261' in the first embodiment and provides the magnetic flux φι only with the first hollow magnet 26'. Similarly, the hollow magnetic conductive sheet 262 absorbs the magnetic force line Φ1 emitted by the first hollow magnet 26〇, and causes the magnetic force line Φ1 to pass through the air-core coil 25, and interacts with the electromagnetic field generated by the air-core coil 25 to generate an electromagnetic force. Move the movable part. In the second and second g-positions of the present invention, the magnetic force Φ1 starts from the lower surface of the n-pole of the first hollow magnet 260, and is absorbed by the middle magnetic sheet 262, and is guided by the hollow magnetic conductive sheet 262. Leading to the slidable _ Qing Chengzhi _, the magnetic force (four) smashed and formed a closed magnetic circuit. The magnetic force "i crosses the air = surface: the electric loop generated by the electric conduction with the air-core coil 25 is 25 days, ', the electromagnetic thrust.. Interaction, and then i is created by the hollow magnetic conductive sheet 262 The magnetic field line Φ1 is used to guide the Φ1 to the 260 of the force line Φ1, and the magnetic line 260 that is concentrated in the circle Φ is not transmitted, and the mother magnet is enough to drive the lens to move. / / And efficiently obtain a schematic diagram of the structure. The lens of this creation Wei Zhuang 'MR lens to cable master actuated device 4 package slide 41, two moving guide parts, · · a squat seat 43, a底” 13 M320089 An air-core coil 45, a hollow magnet group 46, and two linear elastic members 47.

A moving piece. And the fixing seat 43, the base 44 and the hollow magnet group 46 are assembled to form a fixing member of the lens actuating device 4 of the present invention. The fixed shaft 42 is fixedly disposed on the base 44 and disposed on the inner edge of the circular hole shape or the open curved bearing surface of the lens bearing slide 41 as a guide for the movement of the moving member to allow the movement. The moving member can move axially on the fixing member. When the air-core coil 45 is electrically conductive, an electromagnetic field is generated, and the electromagnetic field interacts with the magnetic lines of force emitted by the hollow magnet group 46, thereby generating an electromagnetic thrust, which can be used to push the moving member to perform axial movement. The linear elastic members 47 respectively have a fixing portion (not shown) and a pre-pressing portion (not shown), wherein the fixing portion is connected to the fixing seat 43, and the pre-pressing portion is coupled to the sliding bearing with the lens. The seat 41 and the pre-pressing portion are for applying a lateral pre-pressure P1 to the lens carrying carriage 41. The lateral pre-pressure P1 allows the circular hole-shaped or open-arc bearing surface of the lens-carrying carriage 41 to abut against the surface of the fixed shaft 42 so that the moving member moves in the axial direction to obtain low friction, no free yaw, and high The result of the movement of precision. The line J elastic member 47 also provides an axial restoring force (reset spring force) P2 to the t* moving member, and the axial restoring force P2 has an opposite force to the aforementioned electromagnetic thrust system. When the electromagnetic thrust disappears, the 14 M320089 axial restoring force P2 provided by the linear elastic member 47 returns the moving member to the initial position. In the sixth picture of the dream test, the lens carrying carriage 41 is provided with two sliding slot insertion holes 412, and the fixing seat is thinly provided with two corresponding closed type apertures 434. The linear elastic members 47 are non-coincident linear elastic members respectively connected between the sliding slot insertion holes 412 and the closed type perforations 4 3 4, and the hollow magnet group 46 can be For practical needs, the hollow magnet group 2 of the first embodiment or the hollow magnet group 2 of the second embodiment is selected. With reference to the seventh figure, it is a schematic diagram of the lens actuation I structure of the fourth embodiment of the present invention.

The magnetic circuits of the fourth embodiment and the third embodiment. The principle of the action of the road and the effect achieved are the same. After comparison, the main difference is that the fixing seat 43 of the fourth embodiment is provided with at least one open E-shaped hole 432 instead of the third embodiment. The closed perforation '434' solves the labor involved in the threading step when assembling the closed perforation 434. Since the closed perforation 434 is used as the connection point of the linear elastic member 47 on the solid seat 43, In the assembly, the linear elastic member must be connected to the chute socket 々I of the lens bearing slide 々I, and the other end is passed through the closed perforation 434 and fixed to the yoke fixing seat 43.
