Description

发明名称：一种有利于生产的微型移轴式光学防抖音圈马达结构及装配方法 Title of Invention: Micro-shifting type optical anti-shake voice coil motor structure and assembly method favorable for production

技术领域 Technical field

[0001] 本发明公幵一种音圈马达，特别是一种有利于生产的微型移轴式光学防抖音圈马达结构及装配方法。 [0001] The present invention discloses a voice coil motor, and more particularly to a micro-shifting type optical anti-shake voice coil motor structure and assembly method which are advantageous for production.

背景技术 Background technique

[0002] 现今微型光学防抖音圈马达的技述已被广泛应用在高端的手机，能有效地减少在低光环境下拍出模糊照片的机会，及影片中令人困扰的抖动。但是，相对于一般自动对焦马达，防抖音圈马达的设计比较复杂，生产的合格率及效率较低。因此，所述技述还未普及在中端及低端手机，大部份的手机用户仍未能享受到防抖技术所带来的好处。 [0002] The technology of the miniature optical anti-shake voice coil motor has been widely used in high-end mobile phones, which can effectively reduce the chance of taking blurred photos in low-light environments and the disturbing jitter in the film. However, compared with the general autofocus motor, the design of the anti-shake voice coil motor is complicated, and the yield and efficiency of production are low. Therefore, the above description has not been popularized in mid-range and low-end mobile phones, and most mobile phone users still fail to enjoy the benefits of anti-shake technology.

[0003] 微型光学防抖音圈马达可分为三类，其名称及防抖原理如下： [0003] Micro optical anti-shake voice coil motors can be divided into three categories, the name and anti-shake principle are as follows:

[0004] 一、相机模组移轴式：通过音圈马达控制把镜头和影像传感器一起转动。 [0004] First, the camera module shifting axis: The lens and the image sensor are rotated together by the voice coil motor control.

[0005] 二、镜头平移式：通过音圈马达控制镜头平移，影像传感器不动。 [0005] Second, the lens shifting mode: The lens is controlled by the voice coil motor, and the image sensor does not move.

[0006] 三、镜头移轴式：通过音圈马达控制镜头转动，影像传感器不动。 [0006] Third, the lens shifting axis: The lens is controlled by the voice coil motor, and the image sensor does not move.

[0007] 上述三种马达各有优点，其中，镜头移轴式马达的结构相对简单，有利于生产。 [0007] Each of the above three motors has advantages, and the structure of the lens shifting type motor is relatively simple, which is advantageous for production.

[0008] 一般镜头移轴式光学防抖音圈马达结构（如中国专利公幵号为 CN 101542348 及公幵号为 CN101587222) 包含一个外壳、一个底座、至少两组弹性材料、至少三组磁石、至少三个独立线圈及一个镜头载体，线圈和镜头载体紧密地连接，并一起活动，组成活动结构，磁石、外壳及底座紧密地连接，并不会活动，组成不动结构。两组弹性材料连接镜头载体的上方及下方，加上不动的结构部分，共同组成一个多自由度的弹簧振子***，让镜头能作两个方向的偏转（供光学防抖用），及一个沿光轴的位移（供自动对焦用）。 [0008] A general lens shifting type optical anti-shake voice coil motor structure (such as the Chinese Patent No. CN 101542348 and the public number CN101587222) includes a casing, a base, at least two sets of elastic materials, at least three sets of magnets, At least three independent coils and a lens carrier, the coil and the lens carrier are closely connected and act together to form a movable structure, and the magnet, the outer casing and the base are closely connected, and do not move to form a fixed structure. Two sets of elastic materials are connected above and below the lens carrier, and the fixed structural parts are combined to form a multi-degree-of-freedom spring oscillator system, so that the lens can be deflected in two directions (for optical image stabilization), and one Displacement along the optical axis (for autofocus).

[0009] 通过独立控制每一个线圈的电流，可以达到不同的偏转量及位移量。由于每个线圈需要独立通电，而线圈位于能多自由度活动的镜头载体，两组弹性材料需要通电，并至少包含至少四个独立电路（每个电路之间的电阻不能太少）。因此，两组弹性材料一般包含至少四个独立弹簧。另一方面，线圈需要和弹簧在电路上连接，这需要在活动结构加入至少六个电路连接（可以用焊锡）。例如，在中国专利 CN101542348中的示范实施例，上方一组弹性材料由一个独立弹簧组成，下方一组弹性材料则由四个独立弹簧组成，总共有五个独立弹簧。另一方面，活动结构中需要八个电路连接。 [0009] By independently controlling the current of each coil, different amounts of deflection and displacement can be achieved. Since each coil needs to be independently energized, and the coil is located in a lens carrier capable of multi-degree of freedom, two sets of elastic materials are required. To be powered, and to include at least four separate circuits (the resistance between each circuit should not be too small). Therefore, the two sets of elastic materials generally comprise at least four independent springs. On the other hand, the coil needs to be connected to the spring on the circuit, which requires the addition of at least six circuit connections (which can be soldered) to the active structure. For example, in the exemplary embodiment of Chinese Patent No. CN101542348, the upper set of elastic materials consists of one independent spring and the lower set of elastic materials consists of four independent springs, for a total of five independent springs. On the other hand, eight circuit connections are required in the active structure.

[0010] 在细少的马达中加入大量的独立弹簧及电路连接，可以引致以下问题： [0010] Adding a large number of independent springs and circuit connections to a small number of motors can cause the following problems:

[0011] 一、需要在极细少的活动结构完成多个机械及电路连接，大大增加生产的难度 [0011] First, it is necessary to complete multiple mechanical and circuit connections in a very small active structure, which greatly increases the difficulty of production.

[0012] 二、需要把五个独立弹簧装配在马达中，增加生产的难度。 [0012] Second, it is necessary to assemble five independent springs in the motor to increase the difficulty of production.

[0013] 三、由于结构上复杂，减低了机械上的防撞性，减低通过跌落测试的机会。 [0013] Third, due to the structural complexity, the mechanical crashworthiness is reduced, and the chance of passing the drop test is reduced.

[0014] 另外，一般弹簧及线圈的电路连接的生产工艺是需要人手把线圈的线头引到弹性材料上。在引线过程中员工容易折断线头，导致合格率低、生产效率低、人工成本高。另一方面，引线后线头和弹性材料之间有空隙，要靠导电材料（如焊锡）作为两者的桥梁，把两者焊接在一起。因为空隙大小难以控制，导致空隙不一，容易做成电阻大小不一，甚至接触不良，马达报废，减低生产合格率。 [0014] In addition, in general, the production process of the circuit connection of the spring and the coil requires that the wire end of the coil be manually guided to the elastic material. During the lead process, the employee easily breaks the wire end, resulting in low qualification rate, low production efficiency, and high labor cost. On the other hand, there is a gap between the wire end of the lead and the elastic material, and a conductive material (such as solder) is used as a bridge between the two to weld the two together. Because the gap size is difficult to control, resulting in different gaps, it is easy to make resistors of different sizes, even poor contact, the motor is scrapped, and the production yield is reduced.

[0015] 最后，由于两组弹性材料连接镜头载体的上方及下方，在装配过程中需要在不同方向装弹性材料，并完成机械及电路上的连接工艺，可能需要把半制成品翻转，增加装配及连接工艺的难度，减低生产效率。 [0015] Finally, since the two sets of elastic materials are connected above and below the lens carrier, elastic materials need to be installed in different directions during the assembly process, and the mechanical and electrical connection process is completed, it may be necessary to flip the semi-finished product and increase Difficulty in assembly and joining processes, reducing production efficiency.

[0045] 为了更具体表达本发明所述的结构，下面内容结合具体的四个优选实施方式对本发明所作的进一步详细说明，但不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。 [0045] In order to more specifically describe the structure of the present invention, the following detailed description of the present invention is made in conjunction with the specific four preferred embodiments, but the specific embodiments of the present invention are not limited to the description. It will be apparent to those skilled in the art that the present invention may be practiced without departing from the spirit and scope of the invention.

[0046] 请参看附图 1至附图 6，本发明的核心是一种有利于生产的微型移轴式光学防抖音圈马达结构，其主要包括线圈载体 1、凸台 2和线圈 3，本实施例中，线圈载体 1为不动组件，其和***其它不动结构紧密连接，能支持直接绕线工艺。本实施例中，线圈载体 1呈方形，四角处分别设有直倒角，线圈载体 1的四个侧边外侧分别固定设有一个用于缠绕线圈的凸台 2，每个凸台 2上缠绕有一个线圈 3，线圈 3能支持直接绕线工艺在凸台 2上直接形成，有利于量产，甚至全自动化量产。凸台 2上设有向内斜面 7，向内斜面 7向内倾斜，让线圈 3能更牢固地绕在凸台 2四面，以防止线圈 3从凸台 2上脱出。本实施例中，在线圈载体 1底部固定设有绕线柱 4，每个凸台 2下方对应设置有两个绕线柱 4，分别用于缠绕线圈 3两端的线头 5 ，本实施例中，在线圈载体 1上幵设有线槽 6，线槽 6幵设在凸台 2至绕线柱 4之间，线圈 3的连接线头 5的线缆可设置在线槽 6内。 Referring to FIG. 1 to FIG. 6, the core of the present invention is a micro-shifting type optical anti-shake voice coil motor structure which is advantageous for production, and mainly comprises a coil carrier 1, a boss 2 and a coil 3. In this embodiment, the coil carrier 1 is a stationary component, which is closely connected with other peripheral fixed structures, and can support the direct winding process. In this embodiment, the coil carrier 1 has a square shape, and the four corners are respectively provided with straight chamfers, and the four outer sides of the coil carrier 1 are respectively fixedly provided with a boss 2 for winding the coil, and each of the bosses 2 is wound. There is a coil 3, which can support the direct winding process to form directly on the boss 2, which is advantageous for mass production and even full-automatic mass production. The boss 2 is provided with an inward slope 7 which is inclined inwardly so that the coil 3 can be more firmly wound around the boss 2 to prevent the coil 3 from coming off the boss 2. In this embodiment, a bobbin 4 is fixedly disposed at the bottom of the coil carrier 1, and two bobbins 4 are disposed under each of the bosses 2, respectively for winding the ends 5 of the coils 3, in this embodiment, A wire groove 6 is disposed on the coil carrier 1, and a wire groove 6 is disposed between the boss 2 and the bobbin 4, and a cable of the connection head 5 of the coil 3 can be disposed in the wire groove 6.

[0047] 上述实施例中，以四个凸台 2和四组线圈 3为例对其结构进行说明，具体实施吋，也可以仅设置三个凸台 2和三组线圈 3，或也可以根据实际需要设置更多组。 [0047] In the above embodiment, the structure is described by taking four bosses 2 and four sets of coils 3 as an example. Specifically, only three bosses 2 and three sets of coils 3 may be provided, or may be Actually you need to set more groups.

[0048] 本实施例中，还包括有底座 8、外壳 9、镜头载体 10、磁石 11和弹性材料 12，底座 8和外壳 9固定安装在一起，形成本发明的主体外壳结构，本实施例中，底座 8 上对应于绕线柱 4分别幵设有通孔，底座 8外侧对应于通孔处设有金属片 13，绕线柱 4上的线头 5与金属片 13连接在一起，通过底座 8中的金属片 13，在电路上可以把线圈 3连到马达的底部，方便和相机模组的印刷电路板连接。镜头载体 10通过弹性材料 12安装在线圈载体 1，镜头载体 10的内壁可以和镜头紧密连接，让镜头能作多自由度的活动，以达致自动对焦及防抖的功能。本实施例中，磁石 11 的数量与线圈 3的数量相同，磁石 11固定安装在镜头载体 10上，形成活动结构，磁石 11对应于线圈 3设置。本实施例中，镜头载体 10和线圈 3在机械及电子结构上分幵设计，所以连接镜头载体 10及不动结构（即线圈载体 1、外壳 9和底座 8) 的弹性材料 12并不需要分成至少五个独立弹簧，作多个线圈的独立供电，而采用一体式结构即可，因此，本发明结构能避免在极细少的活动空间结构内完成多个机械及电路连接，亦不需要装配至少五个独立弹簧，大大降低结构及生产的复杂性。本实施例中，采用一个弹性材料 12，能支持镜头载体 10上方没有导电弹性材料的结构，这种结构能避免在不同方向装弹性材料 12和进行电子及机械连接的工艺，亦不需要把半制成品翻转，大大减低装配及连接工艺的难度。 In this embodiment, the base 8 , the outer casing 9 , the lens carrier 10 , the magnet 11 and the elastic material 12 are further included. The base 8 and the outer casing 9 are fixedly mounted together to form the main body outer casing structure of the present invention. A through hole is respectively defined in the base 8 corresponding to the bobbin 4, and a metal piece 13 is disposed on the outer side of the base 8 corresponding to the through hole, and the wire end 5 on the bobbin 4 is connected with the metal piece 13 through the base 8. In the metal piece 13, the coil 3 can be connected to the bottom of the motor on the circuit to facilitate connection with the printed circuit board of the camera module. The lens carrier 10 is mounted on the coil carrier 1 through the elastic material 12. The inner wall of the lens carrier 10 can be closely connected to the lens, so that the lens can perform multi-degree of freedom to achieve the functions of autofocus and anti-shake. In the present embodiment, the number of magnets 11 is the same as the number of coils 3, and the magnet 11 is fixedly mounted on the lens carrier 10 to form a movable structure, and the magnet 11 is disposed corresponding to the coil 3. In this embodiment, the lens carrier 10 and the coil 3 are designed in a mechanical and electronic structure, so that the elastic material 12 connecting the lens carrier 10 and the stationary structure (ie, the coil carrier 1, the casing 9 and the base 8) does not need to be divided. At least five independent springs are used for independent power supply of multiple coils, and the integrated structure can be used. Therefore, the structure of the invention can avoid multiple mechanical and electrical connections in a very small active space structure, and does not require assembly. At least five independent springs greatly reduce structural and production complexity. In this embodiment, an elastic material 12 is used to support the structure without the conductive elastic material above the lens carrier 10. This structure can avoid the process of mounting the elastic material 12 and the electronic and mechanical connection in different directions, and does not need to be half. The finished product is flipped, which greatly reduces the difficulty of assembly and joining process.

[0049] 本发明中，活动结构及不动结构共同组成一个多自由度的弹簧振子***。通过独立控制线圈 3电流的大小及方向，可以独立控制磁石 11向上的力，从而控制镜头能作两个方向的偏转（供光学防抖用），及一个沿光轴方向上的位移（供自动对焦用）。 [0049] In the present invention, the movable structure and the fixed structure together constitute a multi-degree of freedom spring vibration subsystem. By independently controlling the magnitude and direction of the current of the coil 3, the upward force of the magnet 11 can be independently controlled, thereby controlling the deflection of the lens in two directions (for optical image stabilization) and a displacement along the optical axis (for automatic Focusing).

[0050] 本实施例在生产吋，首先把导电线直接绕在线圈载体 1的每个凸台 2上，形成一定圈数的线圈 3，牢固地固定在凸台 2上。最后，把每个线圈 3的两端线头 5，分别经线槽 6绕在绕线柱 4上。在完成所有的绕线工艺后，位于绕线柱 4上的导电线，能在之后的装配工序中，支持和其它导电组件作电路连接。本实施例中，可利用自动绕线设备实现直接绕线，能可靠地及有效率地在凸台 2上进行一定圈数的绕线，实现 3维尺寸和相对位置尺寸均匀，这对提高生产微型马达的合格率起了重要的作用。 [0050] In the present embodiment, in the production of the crucible, the conductive wire is first wound directly on each of the bosses 2 of the coil carrier 1 to form a The coil 3 of a predetermined number of turns is firmly fixed to the boss 2. Finally, the wire ends 5 of each of the coils 3 are wound around the bobbin 4 via the wire grooves 6, respectively. After all the winding processes are completed, the conductive wires on the bobbin 4 can be electrically connected to other conductive components in a later assembly process. In this embodiment, the automatic winding device can be used to realize direct winding, and the winding of a certain number of turns can be reliably and efficiently performed on the boss 2, and the three-dimensional size and the relative position size are uniform, which improves the production. The pass rate of the micromotor plays an important role.

[0052] 一、外壳 9向上； [0052] First, the outer casing 9 is upward;
