PURPOSE:To automatically set under-supporting pins of a double-sided mounting printed board. CONSTITUTION:By driving a setting board 3 in the X direction with a setting board driving device 4, under-supporting pins 10-12 can be moved up and down away from the setting board 3. When exciting by an air cylinder a pin 2 selected by an under-supporting pin selecting device 6 which is provided with the air cylinder, the under-supporting pins 10 and 12 project and get into a set state. Now, the driving action of the setting board driving device 4 is stopped, and then the setting board 3 gets back to the original position and the projecting under-supporting pins 10 and 12 are held by the setting board 3. A printed board is supported from under by all the selected under-supporting pins which are projecting under the printed board except for a part where components are mounted. By specifying the position of the projecting under-supporting pins based on the drawing data about the printed board, the setting of the under-supporting pins can be automated. |
