Abstract

An electronic components mounting device has a plurality of feeder bases 17 attached with tape feeders 18 thereon, and a guide rail 21 and a cylinder 20 for drawing each of the feeder bases 17 independently to a position for replenishing electronic components. When an electronic component runs out of the storage, only the feeder base 17 that is carrying the relevant tape feeder 18 gone out of the stock is drawn to a place for parts replenishment; in the mean time, the mounting actions keep on going by making use of tape feeders 18 attached on other feeder base 17. Machine stop times can be decreased with the mounting device.

Claims

1. An electronic components mounting device comprising:

a feeding section for feeding electronic components; and

a transfer head for picking up an electronic component provided on said feeding section and mounting the component on a substrate, wherein

said feeding section comprises a plurality of feeder bases for detachably attaching parts feeders thereon, and drawing means which draws each of said plurality of feeder bases independently to each other to a position for replenishing electronic components.

2. The electronic components mounting device of claim 1, wherein said parts feeder is a tape feeder, further comprising

a discharge guide section for guiding an empty tape discharged from the tape feeder, and

a cutter provided underneath the discharge guide section for cutting said empty tape;

wherein

said cutter is organized so that a front cut end of said empty tape stays within said discharge guide section when said feeder base is drawn to the position for replenishing electronic components.

3. The electronic components mounting device of claim 1, wherein said parts feeder is a tape feeder, and each of said respective feeder bases is attached with a plurality of tape feeders that handle tapes of a same tape material.

4. The electronic components mounting device of claim 3, wherein respective feeder bases are provided underneath with a cutter for cutting an empty tape discharged from a tape feeder and a reclaim box for reclaiming the empty tape cut by the cutter.

5. A method of mounting electronic components comprising:

attaching parts feeders on each of a plurality of feeder bases; and

transferring an electronic components stored in said parts feeders on a substrate using a transfer head, wherein

for replenishment of electronic components to either one of said parts feeders, only the feeder base that carries the relevant parts feeder is drawn to a position of replenishing electronic components, while mounting actions are kept on going by making use of other parts feeders attached on a feeder base other than the one that is being drawn.

6. The method of mounting electronic components recited in claim 5, wherein said parts feeder is a tape feeder, and each of said feeder bases is drawn so that a front cut end of an empty tape of said tape feeder stays within said discharge guide section for guiding the empty tape.

7. The method of mounting electronic components recited in claim 5, wherein said parts feeder is a tape feeder, and each of said feeder bases is attached with a plurality of tape feeders that handle tapes of a same tape material.

8. The method of mounting electronic components recited in claim 7, wherein empty tapes discharged from the tape feeders in each of said feeder bases are cut and the cut tapes of a same kind are collected in respective reclaim boxes provided in the respective feeder bases.
