Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

Figure 3 shows an exploded perspective view of a mobile camera module package including an actuator of the VCM type according to the present invention.

As shown in FIG. 3, the camera module according to the present invention includes a lens barrel 1 largely equipped with a lens group, an image sensor module 3 for capturing an image passing through the lens barrel 1, And an actuator (2) for moving the lens barrel (1) up and down for the autofocusing operation in the image sensor module (3).

The lens barrel 1 is coupled to the actuator 2 from the upward direction, functions as a lens holder, and is typically formed of a resin such as polycarbonate, and inserted into the actuator 2. An aperture, a condenser lens, and the like are installed at the bottom side. The aperture defines a passage of light passing through the condenser lens, and the condenser lens receives light passing through the aperture to the light receiving portion of the image sensor element described later. IR coated glass is adhered to the upper surface of the lens barrel 1 to prevent foreign matter from penetrating into the aperture or the condenser lens.

The image sensor module 3 includes an image sensor which is coupled from the downward direction of the actuator 2 and attached to a circuit board for receiving and processing light passing through the lens barrel 1. In general, the packaging method of an image sensor for a camera is a flip-chip (chip on flim) packaging method, a wire bonding method of a chip on board (COB) packaging method, and a chip scale package (CSP) method. Among them, a COF packaging method and a COB packaging method are widely used.

The image sensor includes a light receiving unit for receiving light received from the condensing lens of the lens barrel 1 and performing photoelectric conversion, and a signal processing unit for transmitting the signal generated by the light receiving unit as image data. A plurality of electrode pads are formed on one surface of the circuit board and attached to the circuit board, and bumps are formed on the electrode pads. For example, when the image sensor is attached to the COF flip chip packaging method, bumps and anisotropic conductive solids (ACF) or non-conductive liquid polymers (NCP: non-conductive pastes) protruding from the electrode pads are used. Attach it. The bump may be configured of any one of a stud type bump, an electroless bump, and an electrolytic bump. Since the stud type bump may reduce the height of the bump during flip chip pressurization, the step between ceramic leads may be improved. It is also advantageous in terms of improving the reliability of the product.

The actuator 2 includes a case for protecting the interior from the external environment as a drive unit for moving the lens barrel 1 up and down for the autofocusing operation in the image sensor module 3.

As shown in FIGS. 4 and 5, the actuator 2 according to the present invention includes a holder having a plurality of holder PCBs for autofocusing in the image sensor module, a magnet mounted to the holder, Coils located in the magnet, a bobbin coupled to the coil at the outer circumference and the lens barrel at the center, and provided with an energization part electrically connected to the coil on an upper surface thereof, and installed to elastically preload the bobbin. And both ends thereof are formed of a plurality of suspension wires respectively connected to a current-carrying part formed on an upper surface of the holder PCB and the bobbin. 4 is a perspective view of the mobile actuator according to an embodiment of the present invention, and FIG. 5 is an exploded perspective view of the mobile actuator according to FIG. 4.

As shown in FIGS. 4 and 5, the holder 11 has a rectangular parallelepiped shape having a predetermined space therein and an open top surface. The yoke 12 and the magnet 13 combination, and the coil 14 and the bobbin 15 assembly may be accommodated in the holder 11. The bottom surface of the holder 11 is in contact with the bottom surface of the bobbin 15. An upper case 16 and a lower case (ultraviolet cut filter and housing assembly; 17) are respectively coupled to the upper and lower portions of the holder 11. The suspension wire 30 may be directly connected to an upper end portion of the holder 11 having the circuit pattern formed therebetween, the holder PCB being additionally mounted on a pair of faces facing each other of the holder 11. More preferably 21).

Holder PCB 21 is coupled to the opposite surface of the holder 11 as described above, the holder PCB 21 is because the suspension wire 30 is formed of an elastic material such as FR-4 Can improve the sensitivity. In addition, a predetermined circuit pattern is formed on the holder PCB 21, and a current applied from the outside through the circuit pattern can be energized by the suspension wire 30.

In the specific shape of each of the holder PCB 21, a junction portion 21a coupled to the holder 11, a pair of arm portions extending from both ends of the junction portion 21a to have a predetermined length ( 21b) and an insertion portion 21c formed at one end of the arm portion 21b.

The arm portion 21b extends symmetrically from both ends of the junction portion 21a, and the suspension wire 30 may have a desired sensitivity by adjusting the shape and length of the arm portion 21b. On the other hand, as long as the arm portion 21b is formed symmetrically and can provide elastic force to the insertion portion 21c it will be apparent that it is not necessary to be limited to a specific shape.

The insertion portion 21c may be formed as a slot formed at one end of the arm portion 21b or a groove in which the upper portion is opened. The suspension wire 30 is inserted and soldered to the insertion portion 21c. By forming the insertion portion 21c as a slot having a predetermined length in the vertical direction or an open groove, the space for the suspension wire 30 to move in the assembling process can be secured as well as the suspension wire. The coupling between the 30 and the holder PCB 21 can be made easier.

One side of the yoke 12 is mounted on the inner surface of the holder 11 in a pair, and the other side thereof is coupled to the magnet 13, respectively. The yoke 12 serves to increase magnetic efficiency by concentrating the magnetic field generated by the magnet 13 to the coil 14 of the coil-bobbin assembly installed therein at a predetermined distance from the magnet 13. do. The yoke 12 has a polygonal shape corresponding to the shape of the holder 11, and is formed of iron (Fe), cold rolled steel (SPCC), nickel (Ni), or the like having excellent magnetic permeability. It is desirable to. On the other hand, the yoke 12 can be omitted as necessary.

The magnet 13 is coupled to the inner surface of the yoke 12 as described above. A square magnet may be used as the magnet 13, and has a bipolarized shape in the transverse and longitudinal directions, respectively.

The coil 14 has a shape mounted on both sides of the bobbin 15. The coil 14 generates an electric field by a current applied through the holder PCB 21 and the suspension wire 30. The magnetic field generated by the magnet 13 is transmitted to the coil 14, and the coil-bobbin combination can be driven by an electromagnetic force caused by the interaction of the magnetic field and the electric field.

The bobbin 15 is coupled to the pair of coils 14 and driven by electromagnetic force generated by the interaction of the coils 14 and the magnets 13. That is, the outer peripheral portion of the bobbin 15 is coupled to the coil 14 and the lens barrel 1 is coupled to the central portion of the bobbin 15. The bobbin 15 is pressed downward from the upper direction of the bobbin 15 by the suspension wire 30 to contact the bottom surface of the holder 11, wherein the position of the bobbin 15 is a reference point of the lens This can be When a current having a constant magnitude is applied to the coil 14, the electromagnetic force of the bobbin 15 and the elastic force of the suspension wire 30 may be in balance with each other to adjust the focus of the lens.

On the upper surface of the bobbin 15 is formed a current-carrying part 151 which is electrically connected to the coil 14. That is, the energizing part 151 is connected to the coil 14 and one end of the suspension wire 30 is connected to the energizing part 151. Therefore, the current applied through the suspension wire 30 flows into the coil 14 via the energization part 151 formed on the upper surface of the bobbin 15. Of course, although the suspension wire 30 and the coil 14 may be directly connected, the connection operation may be further facilitated by using the energization unit 151.

The energization part 151 formed on the upper surface of the bobbin 15 may be formed at any position on the bobbin 15 according to the length and the arrangement shape of the suspension wire 30. By appropriate selection of the position of the energizing portion 151 and the position of the insertion portion 21c of the holder PCB 21 described above, the sensitivity is improved according to the increase in the effective length of the suspension wire 30, This can bring about the effect of improving the driving accuracy of the lens unit according to the difference. The position of the energizing portion 151 and the position of the insertion portion 21c of the holder PCB 21 will be described later in a specific embodiment.

On the other hand, the conductive part 151 formed on the upper surface of the bobbin 15 and one end of the suspension wire 30 is coupled by soldering. In addition, when electrical coupling is unnecessary by soldering, one end of the suspension wire 30 may be coupled to the conductive part 151 by bonding. In other words, the production process may be simplified by bonding a portion in which the suspension wire 30 is not energized.

Suspension wire 30, the conductive portion formed on the upper surface of the holder PCB 21 and the bobbin 15, both ends of each of the plurality of suspension wire 30 in order to elastically preload the bobbin 15 151, respectively. Both ends of the suspension wire 30 are soldered or bonded.

The suspension wire 30 may be any material as long as it is a material having elasticity, and as the material, a wire formed of an alloy of beryllium copper or brass series may be used. If the suspension wire 30 is thin, the sensitivity is excellent, but when the bobbin 15 is shaken, tilting or sagging is likely to occur. In addition, when the suspension wire 30 becomes thicker, a lot of force is required to drive the bobbin 15, so that the sensitivity is inferior. Therefore, the diameter of the suspension wire 30 can be variously changed depending on the size and performance of the bobbin 15, it is preferable to form to have a diameter of 0.05 mm to 0.2 mm. This problem occurs when the diameter of the suspension wire 30 is smaller than 0.05 mm, the reliability cannot be satisfied in the drop performance test, and when the diameter of the suspension wire 30 is larger than 0.2 mm, the power consumption is too large As a result, the diameter of the suspension wire 30 is preferably in the range of 0.05 mm to 0.2 mm.

In addition, the elastic pressing force by the suspension wire 30 is greatly influenced by not only the thickness of the wire but also by the arrangement of the wires, and the arrangement of the wires increases sensitivity and increases the effective length of the suspension wires 30. This can bring about an effect of improving the driving accuracy of the lens unit according to the difference of the spring constant. This will be described later as a specific embodiment.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 6 is a diagram showing the relationship between the arrangement form of the suspension wire 30 and the position of the energization portion 151 formed on the upper surface of the bobbin 15 and the position of the insertion portion 21c of the holder PCB 21 according to the present invention. A schematic diagram showing an embodiment.

In the present embodiment, the holder PCB 21 is provided to correspond to each surface of the holder 11, for example, when the holder 11 is a top open hexahedron, the holder PCB 21 has four sides of the hexahedron. Are formed on each.

The plurality of suspension wires 30 are arranged in point symmetry with respect to the center of the bobbin 15.

Here, the plurality of suspension wires 30, the connection portion (A) of the suspension wire 30 and the bobbin 15 is substantially connected to the connection portion (B) of the suspension wire 30 and the holder PCB 21. It is preferable to install in a state designed to be located in parallel.

Therefore, if the plurality of suspension wires 30 is composed of four suspension wires as shown in FIG. 6, the plurality of suspension wires 30 are arranged in a "-" shape when viewed from above. It features.

That is, as in the present embodiment, by arranging the plurality of suspension wires 30 in a point-symmetrical manner with respect to the center of the bobbin 15 as in a "□" shape, the vibration of the bobbin 15 in the vertical direction It is designed to make a difference between the 'up and down spring constant' representing the spring constant of the suspension wire 30 and the 'left and right spring constant' representing the spring constant of the suspension wire 30 with respect to the vibration of the bobbin 15 in the left and right directions. Not only can the performance be improved in terms of sensitivity for driving, but also a difference between the upper and lower spring constants and the left and right spring constants, so a guide or axis for moving the lens barrel needs to be installed. There is no design freedom can be increased.

Example  2, 3

7 is a view showing the relationship between the arrangement of the suspension wire 30 and the position of the energization portion 151 formed on the upper surface of the bobbin 15 and the position of the insertion portion 21c of the holder PCB 21 according to the present invention. A schematic diagram showing an embodiment.

In the present embodiment, the holder PCB 21 is provided on a pair of surfaces facing each other of the holder 11, respectively. The plurality of suspension wires 30 are arranged symmetrically with respect to the center of the bobbin 15.

Here, the plurality of suspension wires 30, the connection portion (A) of the suspension wire 30 and the bobbin 15 is located inside the connection portion (B) of the suspension wire 30 and the holder PCB 21. It is preferably installed in a state designed to be located.

Therefore, as shown in FIG. 7, the plurality of suspension wires 30 is composed of four suspension wires, and the connection between the suspension wire 30 and the bobbin 15 is a pair of common parts A1 and A2. When formed, the plurality of suspension wires 30 is characterized in that arranged in an "X" shape when viewed from above.

That is, in the present embodiment, the suspension wire 30 is arranged at an angle in the inward direction so that the 'up and down spring constant' and the bobbin 15 representing the spring constant of the suspension wire 30 with respect to the up and down vibration of the bobbin 15. It is designed to give a difference to the 'left and right spring constant' representing the spring constant of the suspension wire 30 against the vibration in the left and right directions, which can cause performance improvement in terms of sensitivity for its driving, Since there is a difference in the left and right spring constant, there is no need to install a guide or axis for moving the lens barrel can increase the degree of freedom in design.

On the other hand, if the plurality of suspension wires 30 is composed of four suspension wires as shown in Figure 8 and the connection between the suspension wire 30 and the bobbin 15 is separately (A1, A2, A3, A4) When formed, the plurality of suspension wires 30, characterized in that arranged in a "XX" shape when viewed from the upper direction.

In this arrangement, as well as the effect obtained by angularly arranging the suspension wires 30 inwardly as in the "X" -shaped arrangement above, one end of the wire 30 is attached to the holder 11 and the other end is bobbind. By attaching to the upper surface of (15) and arranging in a structure in which predetermined wire portions overlap each other, the effective length of the wire is eventually increased, thereby contributing to the improvement of sensitivity.

9 is a view and a table for the drop test result data of the camera module package according to the present invention.

The experimental results shown in FIG. 9 show drop test result data for each of the leaf spring camera module and the suspension wire camera module having similar sensitivity. As shown in the data, the value of the elastic section modulus, which is a parameter for predicting the degree of deformation of the drop, is about twice that of the suspension wire camera module compared to the leaf spring camera module. This means that the stress applied to the wire spring is about 2 times smaller, and thus, it shows that it is robust to external impact.

Although preferred embodiments of the present invention have been described in detail above, those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Accordingly, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concept of the present invention as defined in the following claims also belong to the scope of the present invention.

Especially in the drop reliability test, it shows more than 2 times superiority to the leaf spring camera module package with similar sensitivity.

In addition, the present invention is designed to make a difference in the vertical spring constant in the longitudinal direction and the left and right spring constant in the transverse direction by arranging the suspension wires in an inward angle to induce a performance improvement in terms of sensitivity for its driving. However, since the upper and lower spring constant and the left and right spring constant can be different, there is no need to install a guide or axis for moving the lens barrel, thereby increasing the design freedom.

Furthermore, the present invention attaches one end of the wire to the holder part and the other end to the upper surface of the bobbin part and at the same time arranges a predetermined wire part to overlap each other, which in turn increases the effective length of the wire, thereby contributing to the improvement of sensitivity. It works.
