平保持が非常に重要となる。 The operation of the printed circuit board support device configured as described above will be described below. First, the printed circuit board 1 is transferred onto the XY table 7 by the printed circuit board loading/unloading section 6. At that time, the positioning lever 15 and the printed circuit board support device 16 are in the state shown by the dashed line in FIG. After that, rotation axis 1
7, the positioning lever 15 and the printed circuit board support device 16 are brought into the solid line state. At that time,
Cylinder 24 is in the returned state and joint 2
6. The suction pad 22 is in a raised state via the second lever 25, the block 23, and the compression spring 27, and the printed circuit board 1 is suctioned by the action of the vacuum generator 28. Then, the cylinder 24 operates and reaches its limit, and the joint 26 and the second lever 2
5. The suction pad 22 descends through the block 23 and the compression spring 27 while holding the printed circuit board 1 under suction, and the printed circuit board 1 is moved to the printed circuit board receiver 20.
and is held horizontally. Furthermore, when the size of the printed circuit board 1 changes, the bracket 19 is moved along the elongated hole provided in the first lever 18 in the X direction, and the bracket 19 is moved along the elongated hole provided in the first lever 18 in the Y direction.
Adjustment can be made by moving the first lever 18 in the axial direction of the rotating shaft 17. When inspecting electronic components mounted on the printed circuit board 1, the X-Y table 7 moves, positions the printed circuit board 1, projects light from the light source 8, and receives the shadow with the camera 9.
In order to correctly produce the shadow, it is very important to hold the printed circuit board 1 horizontally.
