As shown in FIG. 5, a lens assembly 23 is installed at the inspection base 21 of the inspection unit 20, an image chart 22 is disposed at an objective lens side focus position of the lens assembly 23, The camera module C is disposed at the eyepiece side focusing position of the lens assembly 23.

At this time, in order to obtain a high quality inspection result, the inspection base 21 and the image chart 22 provided with the lens assembly 23 are spaced between the D1, the inspection base 21 provided with the lens assembly 23, and the inspection base 21 provided with the lens assembly 23. The intervals D2 of the socket bases 12 on which the camera module C is installed should be precisely spaced at set intervals, and the optical axis and the image chart 22 of the camera module C on the optical axis of the lens assembly 23. ) Should be centered.

Hereinafter, a process of setting positions of the image chart 22 and the socket base 12 based on the installation position of the lens assembly 23 will be described with reference to FIGS. 6 through 12.

First, in order to set the interval between the inspection base 21 and the image chart 22 in which the lens assembly 23 is installed, as shown in FIG. 6, by using the lifting mechanism 170 of the inspection unit 20. In a state where the inspection base 21 is lowered, the first jig 111 is attached to the inspection base 21.

Subsequently, the bottom surface of the first jig 111 is raised and lowered by adjusting the distance between the reference surface of the inspection base 21 and the image chart 22 using the lifting table 132 of the chart position guide unit 110. ) To be in close contact with the upper surface of the image chart 22 seated on the.

In this way, in the state where the bottom surface of the first jig 111 fixed to the inspection base 21 is in close contact with the upper surface of the image chart 22, the objective lens side of the lens assembly 23 assembled to the guide member 24 is provided. The distance between the inspection base 21 and the image chart 22 may be determined corresponding to the focal position. Therefore, after acquiring an image image of the image chart 22 by directly driving the camera module C, an iterative process of adjusting the height of the image chart 22 according to the state of the image image may be omitted.

As described above, after the interval between the inspection base 21 and the image chart 22 is determined, the first jig 111 is removed from the inspection base 21.

Next, in order to align the optical axis of the lens assembly 23 with the center of the image chart 22, the laser indicator 121 is disposed on the guide member 24 of the inspection base 21. In order to guide the assembly position of the laser indicator 121, the guide member 24 is provided with a guideline 24a for aligning the position of the cross-shaped reference line provided from the laser indicator 121, and the guideline 24a. ) Is set to intersect on the optical axis of the lens assembly 23. Therefore, when the cross reference line of the laser indicator 121 is installed in accordance with the guideline 24a, the cross reference line of the laser indicator 121 intersects on the optical axis of the lens assembly 23.

Subsequently, as shown in FIG. 7, the cross reference line 121a provided through the laser indicator 121 installed in the inspection base 21 is displayed on the image chart 22, so that the inspection base 21 is provided. The alignment mark 22a of the image chart 22 may be aligned with the cross reference line while rotating the rotary table 131 rotatably supported about the vertical axis.

In this case, since the height of the lifting table 132 is adjusted on the rotating table 131, the interval between the inspection base 21 and the image chart 22 is changed in the process of rotating the rotating table 131. Is prevented.

Next, to align the optical axis of the camera module C on the optical axis of the lens assembly 23, as shown in FIG. 8, an alignment mark in the form of a crosshair is formed on the socket base 12 of the rotating unit 10.

Specifically, as shown in FIG. 10A, in a state in which the socket 13 rotatably installed on the socket base 12 is rotated to face the upper side, a first fastening member such as a screw (not shown) is used. One surface of the second jig 141 is fixed in close contact with the socket 13. In this case, when the alignment mark of the cross-shaped shape provided in the second jig 141 is positioned at the lens center of the camera module C, the alignment mark of the second jig 141 may be positioned on the optical axis of the camera module C. . On the other hand, in order to accurately install the second jig 141 on the socket 13, the second jig 141 mounting surface of the socket 13 has a cross-shaped guide line coinciding with the optical axis of the camera module C. Can be prepared.

Subsequently, when the socket 13 is rotated 180 degrees as shown in FIG. 10B, the other surface of the second jig 141 is in close contact with the socket base 12. In this state, the first fastening member fixing the second jig 141 to the socket base 12 using a second fastening member (not shown) such as a screw, and fixing the second jig 141 and the socket 13. Remove.

Subsequently, when the socket 13 is rotated 180 degrees as shown in FIG. 10 (c), the cross mark of the second jig 141 is aligned with the optical axis of the camera module C. 141 may be secured to the socket base 12.

Next, in order to set the interval between the inspection base 21 in which the lens assembly 23 is installed and the socket base 12 in which the camera module C is installed, as shown in FIG. 11, the inspection unit 20. In the state in which the inspection base 21 of () is lowered, the third jig 161 is installed on the guide member 24 of the inspection base 21, and the inspection is performed through the lifting mechanism 170 as shown in FIG. 12. By raising the base 21 to bring the upper end of the third jig 161 into close contact with the camera module C, the inspection base 21 and the socket base 12 are matched to the eyepiece side focal length of the lens assembly 23. ), The interval D2 can be set.

At this time, the height of the third jig 161 is set to determine the interval between the inspection base 21 and the socket base 12 corresponding to the eyepiece lens side focal length of the lens assembly 23, so that the inspection base ( The rising position of 21) can be set accurately.

After the raised position of the inspection base 21 is set as described above, when the third jig 161 is removed and the lens assembly 23 is assembled to the guide member 24, the objective lens side of the lens assembly 23 is focused. The image chart 22 is disposed at the position, and the camera module C is disposed at the eyepiece side focal position of the lens assembly 23, as well as the optical axis of the camera module C on the optical axis of the lens assembly 23. And the center of the image chart 22 are positioned.
