As shown in the above figures, the camera module active alignment apparatus 100 of the present invention includes a diagram portion 110 for inspection, a first manipulator 120, a second manipulator 130, a lifting portion 140, and a buffer portion 150.
The inspection chart portion 110 is disposed at a predetermined position on the conveyor line 72 for conveying the tray T on which the image sensor S and the lens L are mounted, and may include a top chart portion 111 disposed above the predetermined position in a lateral direction and a pair of side chart portions 112 disposed on both sides of the predetermined position in a longitudinal direction. For example, as shown in fig. 7, the top chart portion 111 may be configured to include a top chart 111a arranged in parallel to the X-Y plane in an upper region of the specified position; a supporting frame 111b supporting the top graph 111a; and a moving mechanism 111c for moving the top sheet 111a up and down on the support 111 b. Further, the side chart portion 112 may be configured to include side charts 112a arranged in parallel to the X-Z plane on both sides of the upper region of the specified position, that is, on both sides of the conveying line 72; a supporting frame 112b supporting the side graph 112a; a moving mechanism 112c for moving the side table 112a up and down on the support frame 112b; and an angle adjusting mechanism 112d capable of adjusting the inclination of the side chart 112a about the X-axis.
The first operator 120 is disposed below a designated position on the conveyor line 72, and is configured to be able to adjust the position of the image sensor S in a state where the image sensor S mounted on the tray T conveyed to the designated position is lifted. Such a first operator 120 may include a first grip portion 121 for gripping the image sensor S mounted on the tray T and a first adjustment portion 122 capable of adjusting the position of the first grip portion 121. For example, as shown in fig. 8, the first grip 121 may have four jaws (jaw) capable of fixing the image sensor S. The first adjustment unit 122 may be constituted by a multi-axis table including, for example, an X-axis moving mechanism 122a, a Y-axis moving mechanism 122b, a Z-axis moving mechanism 122c, a Z-axis rotating mechanism 122d, an X-axis inclination adjusting mechanism 122e, and a Y-axis inclination adjusting mechanism 122f, and the Z-axis moving mechanism 122c is preferably provided to have a stroke that can reciprocate the first holding unit 121 between a position to separate from the conveying area of the tray T and a position to lift the image sensor S mounted on the tray T to the upper side of the tray T. Here, the X axis may be a conveying direction of the tray T, the Y axis may be a direction orthogonal to the X axis on a horizontal plane, and the Z axis may be a direction orthogonal to a horizontal plane including the X axis and the Y axis.
The second operator 130 is disposed in front of or behind a designated position on the transfer line 72, and is configured to adjust the position of the lens L in a state where the lens L mounted on the tray T transferred to the designated position is moved to the upper side of the image sensor S. Such a second manipulator 130 includes a second grip 131 capable of gripping the lens L mounted on the tray T; a second adjusting part 132 capable of adjusting the position of the second grip part 131 so as to align the assembly position of the lens L with respect to the image sensor S; and a lifting part 140 capable of moving the second adjusting part 132 up and down so that the second grip part 131 enters or withdraws from the conveying area of the tray T. For example, as shown in fig. 9, the second grip 131 may be preferably formed in a forceps shape capable of grasping both side surfaces of the lens L, and the second adjustment part 132 may be formed of a multi-axis stage including an X-axis movement mechanism 132a, a Y-axis movement mechanism 132b, a Z-axis movement mechanism 132c, an X-axis inclination adjustment mechanism 132d, and a Y-axis inclination adjustment mechanism 132e, and the X-axis movement mechanism 132a is preferably provided with the following stroke: the stroke enables the second grip 131 to reciprocate between a position where the second grip 131 is separated from the tray T and a position where the second grip 131 grips the lens L mounted on the tray T and positions the lens L above the image sensor S when viewed in a plane.
The elevation part 140 is configured to be able to elevate the second operator 130 so as to bring the second operator 130 into the conveying area of the tray T or to lower the second operator 130 so as to disengage the second operator 130 from the conveying area. Specifically, the elevation part 140 can raise the second adjusting part 132 in the Z-axis direction so that the second grip part 131 can manipulate the lens L in a state of entering the conveying area of the tray T, or can lower the second adjusting part 132 in the Z-axis direction so that the second adjusting part 132 moves to a position capable of being separated from the conveying area of the tray T, thereby moving the tray T to a subsequent process. For example, as shown in fig. 9, the lifting part 140 may be configured to include a supporting frame 141 supported on the ground structure; a guide 142 for guiding the up-and-down movement of the second operator 130 on the support frame 141; a ball screw 143 disposed along the Z-axis direction and rotatably supported by the support frame 141; a ball nut 144 fixed to the second operator 130 and coupled to the ball screw 143; and a driving part 145 for rotating the ball screw 143, wherein the ball nut 144 moves along the rotation direction of the ball screw 143 and simultaneously moves the second manipulator 130 along the Z-axis direction.
The camera module active alignment apparatus 100 of the present embodiment as described above can control at least one of the first and second operators 120 and 130 so as to align the optical axes of the image sensor S and the lens L on the basis of the image of the inspection chart section 110 taken by the image sensor S.
The buffer 150 may temporarily store the tray T between the supply-side end of the conveyor line 72 and a predetermined position, and may include a stopper 151 capable of selectively stopping the tray T conveyed to the predetermined position along the conveyor line 72, and a lifting mechanism 152 capable of moving the tray T stopped by the stopper 151 away from the conveyor line.
Here, when the tray T is present at the designated position, the stopper 151 enters the tray conveying area to prevent a new tray T 'from being conveyed to the designated position, and when the tray T is not present at the designated position, the stopper 151 is separated from the tray conveying area so that the new tray T' can be conveyed to the designated position.
Further, the lifting mechanism 152 may be controlled to: in a state where the tray T is stopped by the stopper 151, the elevating mechanism 152 is elevated, thereby moving a new tray T' away from the conveyor line 72; when the tray T is not present at the designated position, the elevating mechanism 152 descends, so that a new tray T' can be mounted on the conveyor line 72.
In addition, a sensing sensor (not shown) that can sense the tray T may be provided at a designated position of the transfer line 72, and the stopper 151 and the elevating mechanism 152 may be controlled according to a sensing signal sensed in the sensing sensor.
In the drawings, fig. 10 to 12 are sectional views showing the function of the active alignment device for a camera module of the present invention. Specifically, fig. 10 is a diagram showing a state in which the tray is conveyed to a specified position for active alignment, fig. 11 is a diagram showing a state in which the image sensor and the lens are aligned by the first manipulator and the second manipulator, and fig. 12 is a diagram showing a state in which the subsequent tray is moved from the buffer portion to the specified position.
First, as shown in fig. 10, in the process of moving the tray T with the image sensor S and the lens L mounted thereon from the supply end portion to the discharge end portion of the conveyance line 72, the first manipulator 120 and the second manipulator 130 are located below the conveyance line 72, respectively, so that the tray T can be freely moved without interfering with the first manipulator 120 and the second manipulator 130.
The tray T may be provided to a designated position on the conveyor line 72. Here, the designated position may be set to a position where the first operator 120 can be lifted up to hold the image sensor S. A stopper (not shown) for stopping the tray T conveyed along the conveyor line 72 at a specified position may be provided at the specified position; and a lifting mechanism (not shown) for moving the tray T stopped by the stopper away from the conveyor line 72, wherein a connector may be provided to the lifting mechanism, the connector may be electrically connected to the image sensor S and supply power to the image sensor S or may transfer an image obtained by the image sensor S to an external device.
Further, a buffer 150 that temporarily stores a new tray T' is provided upstream of the predetermined position of the conveyor line 72.
After the tray T moves to the designated position on the conveyor line 72, as shown in fig. 11, the first adjusting portion 122 of the first operator 120 lifts the first holding portion 121 to a position where the image sensor S can be held, and after the first holding portion 121 holds the image sensor S, the first adjusting portion 122 lifts the first holding portion 121 further and lifts the image sensor S to the upper side of the tray T.
Next, the lifting/lowering unit 140 lifts the second manipulator 130 up and into the upper side of the tray conveyance area, and after the second adjusting unit 132 of the second manipulator 130 moves the second holding unit 131 to a position where the lens L can be held, the second holding unit 131 holds the lens L, and then the second adjusting unit 132 further moves the second holding unit 131 to position the lens L above the image sensor S.
As described above, the position of the image sensor S gripped by the first grip 121 of the first manipulator 120 is adjustable by the first adjusting portion 122 of the first manipulator 120, and the position of the lens L gripped by the second grip 131 of the second manipulator 130 is adjustable by the second adjusting portion 132 of the second manipulator 130.
According to the present embodiment, since the inspection chart portion 110 (see fig. 4) is disposed above the specified position, the assembly state of the image sensor S and the lens L can be confirmed in real time by the chart image obtained by the lens L in the image sensor S, the relative positions of the image sensor S and the lens L can be finely adjusted by at least one of the first and second operators 120 and 130 while the best focus position is found, and the assembly position of the image sensor S and the lens L can be aligned accordingly.
In particular, as the inspection chart portion 110 is constituted by the top chart portion 111 disposed on the upper side of the designated position on the conveyor line 72 and the side chart portions 112 disposed on both sides of the designated position, it is possible to efficiently align even when the angle of view of the image sensor S is large.
Further, the first manipulator 120 and the second manipulator 130 are respectively disposed below the conveyor line 72 and are configured to enter the conveying area of the tray T for assembling the image sensor S and the lens L, and to be separated from the conveying area of the tray T again after the completion of the assembling of the image sensor S and the lens L, so that the wide-angle image sensor S can be effectively fitted by disposing the top chart part 111 and the side chart part 112 together in the apparatus. Furthermore, the first and second operators 120 and 130 can control the assembly positions of the image sensor S and the lens L, respectively, independently, so that various forms of the image sensor S and the lens L can be easily assembled.
In addition, in the process of realizing the assembly of the image sensor S and the lens L in a state where the tray T is supplied to the specified position as described above, the sensing sensor arranged at the specified position can sense the presence of the tray T. At this time, as the stopper 151 of the buffer 150 disposed upstream of the designated position is lifted up to enter the tray conveying area, the new tray T' supplied to the conveyor line 72 may be restricted from being conveyed to the designated position by the stopper 151. Then, the elevating mechanism 152 of the buffer 150 is elevated to raise the new stopper T 'stopped by the stopper 151 and separate it from the conveyor line 72, so that the tray T' can be temporarily stored.
After the alignment and assembly of the image sensor S and the lens L are completed, as shown in fig. 12, the first grip portion 121 is lowered by the first adjustment portion 122 of the first manipulator 120 to a position where the image sensor S can be mounted on the tray T, and after the grip of the image sensor S by the first grip portion 121 is released, the first grip portion 121 is further lowered, so that the interference of the first manipulator 120 is avoided during the conveyance of the tray T.
Next, after the second grip portion 131 is moved to a position not overlapping the tray T by the second adjusting portion 132 of the second manipulator 130, the second manipulator 130 is lowered and separated from the conveying area of the tray T by the lifting portion 140, so that the interference of the second manipulator 130 is avoided during the conveying of the tray T.
As described above, after the first and second operators 120 and 130 are moved to positions out of the conveying area of the tray T, the tray T fixed at the designated position is conveyed to the discharge side of the conveying line 72, and the assembled camera module is conveyed to the subsequent process.
According to the present embodiment, the first manipulator 120 and the second manipulator 130 are respectively disposed below the conveyance line 72, and are configured to enter the conveyance area of the tray T for the assembly of the image sensor S and the lens L, and to be separated from the conveyance area of the tray T again after the assembly of the image sensor S and the lens L is completed, so that the wide-angle image sensor S can be effectively fitted by disposing the top chart portion 111 and the side chart portion 112 together in the apparatus. Furthermore, the first and second operators 120 and 130 can control the assembly positions of the image sensor S and the lens L, respectively, independently, so that various forms of the image sensor S and the lens L can be easily assembled.
In addition, when the tray T is out of the designated position on the transfer line 72 after the alignment and assembly of the image sensor S and the lens L are completed, it is sensed by the sensing sensor that there is no tray at the designated position. In this state, the elevating mechanism 152 of the buffer 150 descends and mounts a new tray T 'on the transfer line 72, and then the stopper 151 descends and enables the new tray T' to move toward a designated position along the transfer line 72.
The transfer line 72 as described above may be provided to pass the tray T between the adhesive applying part and the adhesive curing part through the active alignment device 100, and the buffer part 150 may temporarily store the tray T between the adhesive applying part and the active alignment device, so that the moving time of the tray T may be shortened, and thus the total throughput of the apparatus may be increased.
