Electronic parts are mounted onto a substrate. A parts supply device holds a plurality of electronic parts and moves to be positioned at a predetermined parts take-out position. The parts supply device includes a readable and writable memory for storing data indicative of the plurality of electronic parts held therein. A reading device reads the data stored in the readable and writable memory provided in the parts supply device when the parts supply device moves relative to the reading device to the predetermined parts take-out position. The electronic part is extracted from the parts supply device position at the predetermined parts take-out position and mounted on a substrate.

Electronic parts mounting method employing memory equipped parts supply

An apparatus is for mounting electronic parts onto a substrate. The apparatus includes a parts supply device for holding a plurality of electronic parts and for moving to be positioned at a predetermined parts take-out position. The parts supply device includes a readable and writable memory for storing data indicative of the plurality of electronic parts held therein. The apparatus further includes a reading device for reading the data stored in the readable and writable memory provided in the parts supply device when the parts supply device moves relative to the reading device to the predetermined parts take-out position. The electronic part is extracted from the parts supply device position at the predetermined parts take-out position and mounted on a substrate.

Electronic parts mounting apparatus having memory equipped parts supply

An electronic parts mounting method for taking out from a parts supply device having a plurality of electronic parts at least one of the electronic parts, and mounting the part at a predetermined position of a substrate to be manufactured, includes steps of storing quantity of parts, which is held by each parts supply device, in a storing section provided in each parts supply device, rewriting the quantity of parts according to number of parts taken out from the parts supply device by a calculating section provided in each parts supply device, reading out an initial value of the quantity of parts held by each parts supply device, by a control section provided in an electronic parts mounting machine, calculating one of the quantity of parts required for the substrate and period of time required for mounting the part on the substrate by a calculating section provided in the electronic parts mounting machine, and carrying out, in advance, a parts shortage advance notification in each parts supply device based on a result of the calculating step.

Electronic parts mounting method

In the mounting of an electronic component, a holding member is rotated by a predetermined angle prior to actual holding of the electronic parts, thereby to detect a center of the holding member from at least two positions of the rotation angle, and the rotation center of the holding member is found by a calculation based on the detected center of the holding member. The position of the electronic parts against a circuit board then is corrected on the basis of a deviation between the position of the rotation center and the center of the holding member.
