Abstract
A method of examining a position of at least one board-support pin which is positioned on a board-support base for supporting a printed-circuit board under a back surface thereof, the method including the steps of taking an image of the board-support pin, at a position opposed to a free end of the pin, judging whether the position of the board-support pin is appropriate, based on the taken image, and producing judgment information indicative of a result of the judgment.
Claims16
An apparatus for positioning at least one board-support pin on a board-support base for supporting a printed-circuit board under a back surface thereof, the apparatus comprising:
- a pin fixing device which fixes the board-support pin to the board-support base;
- an image taking device which takes an image of the board-support pin at a position opposed to a free end of the pin fixed to the board-support base by the pin fixing device;
- a moving device which moves at least one of the image taking device and the board-support base relative to the other of the image taking device and the board-support base in a direction parallel to the board-support base;
- a controller which controls the moving device such that the image taking device is positioned at the position opposed to the free end of the board-support pin;
- and
- a judging device which judges whether the position of the board-support pin is appropriate, based on the image taken by the image taking device, and which produces judgment information indicative of a result of the judgment.
An apparatus for positioning at least one board-support pin on a board-support base for supporting a printed-circuit board under a back surface thereof, the board-support pin having an air passage formed therethrough in an axial direction thereof, and two openings at axially opposite ends thereof where the air passage opens, the apparatus comprising:
- a pin positioning device which positions the board-support pin at an arbitrary position on a flat surface of the board-support base;
- and
- a pin fixing device which fixes the board-support pin to the board-support base at said arbitrary position on said flat surface thereof,
- wherein the pin positioning device holds the board-support pin and applies compressed air into one of the two openings of the pin so that the compressed air is blown from the other opening of the pin.
