Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a socket alignment device for a camera module,

The present invention relates to an apparatus for aligning a camera module to check the post-manufacturing performance of a compact camera module (CCM) used in a digital camera for mobile communication and the like. And a camera module alignment device for pressing the upper part of the camera for connection.

Generally, the digital camera module is subjected to tests such as focus adjustment and resolution inspection after manufacturing. The camera inspection device places the camera module in the socket on the device and electrically connects the camera module and the camera inspection device to each other. The camera module is electrically connected to the inspection device, is supplied with operating power, is controlled by a control signal, and transmits a photographing result or inspection result. Therefore, since the electrical connection is made after the corresponding contact (not shown) of the pin-shaped connection (not shown) socket of the camera module is contacted, the camera module must be pressed downwardly after being seated in the socket, The sockets are surely electrically connected and aligned with each other.

Hereinafter, a socket aligning apparatus for a camera module according to the related art will be described with reference to FIGS. 1 and 2. FIG.

As shown in FIGS. 1 and 2, a socket 11 on which a camera module (not shown) is seated and a camera mounted thereon are pressed on the inspection apparatus 10 so that the connection portion of the camera contacts the connection portion 12 of the inspection apparatus And an alignment plate (40) for aligning in the socket (11). The alignment plate 40 includes a pushing portion 41 for pressing the camera module and an inspection window 42 opened at an angle larger than the camera wide angle so that inspection of the camera module can be performed. That is, the lens edge portion of the camera module is pressed around the inspection window.

The aligning plate 40 is fixed to the horizontally moving member 30 which moves horizontally by the horizontal actuator 60 and to the vertically moving member 20 which moves vertically by the vertical actuator 70. The horizontally moving member 30 includes a guide projection 31 engaging with the guide 50 coupled to the vertically movable member 20. [

Since the vertical actuator 70 and the horizontal actuator 60 of the above-described conventional camera module alignment apparatus use a pneumatic cylinder, a cylinder must be provided, and an air piping is required. Therefore, the volume of the apparatus is increased, There is a problem that a noise due to a compression hole is generated.

In addition, since the camera is pressed through the two-axis linear movement, when the pneumatic actuator is slightly driven or an error occurs, even if the pneumatic actuator is slightly driven, the pressing portion can not be positioned accurately. (41) directly touches the lens, thereby causing a defect in the camera module.

In addition, even if a motor is used without using a pneumatic cylinder, if the camera module is aligned with the socket by two-axis linear movement, a rack pinion gear is formed, a screw and a guide nut are used, It may cover the wide angle of the lens or cause a defect in the camera module lens.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a camera module socket aligning device for pressing a camera by uniaxial rotation without two-axis linear movement.

According to an aspect of the present invention, there is provided a camera module comprising: an inspection apparatus main body having an inspection unit having a socket on which a camera module is mounted; a camera module alignment member having a pressing surface for pressing the camera module, And a camera module socket alignment device having an actuator for rotating the camera module alignment member while the pressing surface of the camera module alignment member is held in a direction for pressing the camera module, to provide.

It is preferable that the pivoting means is a link member having one end rotatably coupled to the inspection apparatus main body and the other end rotatably coupled to the camera module alignment member. In this case, the link member may be four links arranged on both sides of the inspection apparatus main body and the camera module alignment member, and may include a rotation shaft coupling one end of each link to the inspection apparatus main body, The distance between the rotation axes coupled to the camera module alignment member is preferably the same for all four links.

The other end of each link is rotatably coupled to a connecting link, and the connecting link is coupled to the camera module aligning member.

Preferably, the actuator is a drive motor that rotates at least one rotation axis of each link.

The camera module aligning member may be coupled to the camera module aligning member such that the camera module aligning member is connected to the camera module aligning member in parallel or spaced apart from the camera module aligning member, The camera module aligning member is positioned on the socket on which the camera module is mounted by the rotation of the link, and then the camera module aligning member moves toward the rotating plate side to linearly press the camera module.

Preferably, the camera module alignment member is coupled to a moving shaft protruding in a linear moving direction, and the rotating plate is formed with a through hole through which the moving shaft can pass.

A cam member rotatable by the second driving means; and a stopper protruding from a portion of the moving shaft through the through-hole at a position where the cam member interferes with a part of a path through which the cam member rotates, As shown in FIG. Further, it is possible to further include at least one gear member capable of adjusting the moving speed and direction of the cam member between the second driving means and the cam member, and the gear member is coupled to the rotation shaft of the second driving means And a second gear that rotates together with the cam member and meshes with the first gear.

The camera module alignment member may include an inspection window opened at an angle of at least the lens wide angle of the camera module when the camera module is pressed.

According to the present invention as described above, since the camera module can be easily aligned with the uniaxial rotating structure, the structure of the inspection apparatus can be simplified, and the manufacturing cost of the apparatus can be reduced.

Further, according to the present invention, since the member for aligning the camera module can press the camera module at the correct position, there is a possibility that the malfunction occurs in the inspection or the probability of damaging the camera module lens may be significantly reduced.

3 to 7, a camera module socket aligning apparatus according to the present invention will be described in detail.

3, the camera module socket aligning device is mounted on an inspection apparatus main body 110 having an inspection unit 112 in which a socket 111 on which a camera module is mounted is formed. A first link 120 and a second link 121 having one end rotatably coupled to one side of the inspection apparatus main body 110 and a third link 130 rotatably coupled to the other side of the inspection apparatus main body 110. [ A second link 122, and a fourth link 123. The other ends of the first to fourth links 120, 121, 122 and 123 are rotatably coupled to the connection link 130 to which the camera module alignment member 140 is coupled. The first to fourth links 120, 121, 122, 123 are arranged on both sides of the camera module alignment member 140, and are parallel to each other.

4 to 7, one end of the first link 120 is rotatably coupled to one side of the inspection apparatus main body 110 by a first rotation axis 150, and the other end is rotatably coupled to a second rotation axis 151 To the one side of the connection link 130 to which the camera module alignment member 140 is coupled. One end of the second link 121 is rotatably coupled to one side of the inspection apparatus main body 110 by the third rotation axis 160 and the other end is rotatably coupled to the side of the connection link 130 by the fourth rotation axis 161. [ And is rotatably coupled to one side. Although not shown, the third link 122 and the fourth link 123 are rotatably coupled to the other side of each of the inspection apparatus main body 110 and the camera module connecting link 130 by a rotation axis. Each of the links has the same length, and the intervals between the rotational shafts coupled to both ends of each link are all the same.

Since the position of the inspection apparatus main body 110 is fixed and links between the first to fourth links 120, 121, 122 and 123 are connected to the connection link 130 and the inspection apparatus main body 110, And as shown in Fig. 7, when one link rotates, the four links simultaneously rotate at the same angle. Therefore, even if the first to fourth links 120, 121, 122 and 123 rotate, the camera module aligning member 140 moves while maintaining the initial posture. That is, when the rotary shafts coupled to one end of the first to fourth links 120, 121, 122 and 123 are all on the same horizontal plane, the rotary shafts of the other end are all at the same height. Therefore, the connection link 130 and the camera module alignment member 140 can be maintained in a posture parallel to the horizontal plane, regardless of the rotation angle of the link.

In this embodiment, the first link 120 is a drive link, and the first rotation shaft 150 is coupled to the drive motor 170. [

The driving motor 170 may be a servomotor capable of rotating in the forward and reverse directions, or may be a step motor, and the driving is controlled according to whether or not the socket of the camera module is seated and the inspection is completed.

The camera module alignment member 140 presses the camera module toward the socket 111 at the upper part when the camera module is seated in the socket 111 so that the camera module is aligned at the correct position and is electrically connected to the inspection device 110 do.

When the inspection apparatus is not operating, the camera module alignment member 140 rotates the first link 150 so as to move away from the inspection portion 112 in which the socket is formed (i.e., in the direction of the arrow in FIG. 7). The second to fourth links 121, 122, 123 are driven by the first link 120, which is the driving link, and rotate at the same angle. Accordingly, the camera module alignment member 140 is separated from the inspection unit 112, and a space is formed in which the camera module (not shown) can be placed in the socket.

When the camera module (not shown) is seated in the socket 111 of the inspection unit 112, the camera module alignment member 140 moves to the inspection unit 112 side, The link 150 is rotated in the opposite direction (i.e., the arrow direction in Fig. 5).

6, when the camera module alignment member 140 is rotated until it contacts the inspection unit, the upper surface of the camera module that is seated on the socket 111 is pressed and aligned to the correct position by further moving to the socket side, (Not shown). At this time, since the camera module alignment member 140 maintains the horizontal plane, the camera module can be aligned in a horizontal direction so that the upper surface of the camera module is horizontal.

8 to 11 illustrate another embodiment of the present invention.

As shown in FIG. 8, in this embodiment, a configuration for fine adjustment is provided because it is difficult to precisely locate the camera module in the socket 111 only by link rotation. For example, since the camera module (not shown) is inserted into the socket 111 of the inspection portion 112 and pressed in the vertical direction, the link rotation always exerts a force in the tangential direction of the rotary arc, The camera module, the camera module alignment member 140, the surface of the inspection unit 112 or the inner surface of the socket 111 can be abraded by a plurality of operations due to the difficulty of pressing the camera module, the camera module alignment member 140, May not be achieved.

Accordingly, the camera module alignment member 140 is moved to the spaced portion on the socket 212 of the inspection unit through the link 220 and then vertically moved to align the camera module with the socket 212 accurately.

8 and 9, the rotation plate 230 is coupled with the four links 220 that are rotated by the driving motor 270, And a camera module alignment member 240 connected to the movable shaft 250. The vertical movement shaft 250 is fixed to the camera module alignment member 240 and is movable along the shaft movement hole 232 formed in the rotation plate 230 and is coupled to the rotation plate 230 with the spring 256 . A stopper 254 is provided on the vertical movement shaft 250 and a spring 256 is provided between the stopper 254 and the lower end of the shaft movement hole 232 of the rotation plate 130 to be engaged with the vertical movement shaft 250 The camera module alignment member 240 can be held at a predetermined interval in the rotation plate 230. [

The vertically moving shaft 250 is provided with a protruding pushing part 252 for vertical movement of the camera model aligning member 240. A servo motor 280 for moving the vertical moving shaft 250 is further provided in addition to the driving motor 270. The first gear 282 is coupled to the rotating shaft of the servo motor 280. [ A second gear 284 is engaged with the first gear 282 and a bar-shaped cam member 286 which is rotated together with the rotation shaft and extends to one side of the rotation shaft is engaged with the rotation shaft of the second gear 284.

The cam member 286 rotates together when the first gear 282 and the second gear 284, which are driven by the servo motor 280 and are continuously coupled thereto, rotate. There is a portion of the cam member 286 that interferes with the pushing portion 252 of the vertical moving shaft 250 during the rotation section. Therefore, while the cam member 286 rotates, the vertical movement shaft 250 can be moved down by pushing the pressing portion 252. [ Accordingly, the camera module alignment member 240 also moves together.

11, after the camera module alignment member 240 is positioned on the socket 212 on which the camera module 240 is mounted by the rotation of the drive motor 270, the servo motor 280 is driven The camera module alignment member 240 is moved toward the socket 212 to press the camera module to align the camera module with the correct position and to be electrically connected to the inspection device.

In the above-described embodiment, only one drive motor is provided, but it may be coupled to any link, and a plurality of drive motors may be provided. It may also be a drive means for pushing or pulling one or more links in place of the drive motor. That is, it may be a driving means capable of rotating the link.

In the above-described embodiment, the number of links is four, but the number of links is not limited to four, and may be more or less.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Will be apparent to those of ordinary skill in the art.
