Mounting apparatus of electronic components and mounting methods of the same

A method of mounting electronic components comprising the steps of:

• detecting a deviation of a line-sensor from a first predetermined axis,
• compensating for said deviation of said line sensor from said first predetermined axis by rotating said line sensor such that a longitudinal axis of said line sensor is parallel with said first predetermined axis,
• picking up electronic components stacked in part feeders in sequence with a plurality of aligned nozzles by transferring a carriage head holding the aligned plurality of nozzles along a second predetermined axis and above the part feeders disposed along the second predetermined axis,
• taking images in sequence of the electronic components vacuum chucked by said nozzles by transferring said carriage head comprising the aligned nozzles above said line-sensor disposed adjacent a substrate and said part feeders, said longitudinal direction of the line-sensor across at substantially right angles to said second predetermined axis, said line sensor being stationary when taking images of said electronic components,
• recognizing positions of said electronic components vacuum chucked by said nozzles based on the taken images, and
• mounting said electronic components vacuum chucked by said nozzles in sequence onto specified coordinate spots by transferring said carriage head above said substrate based on the recognized positions.

A method of mounting electronic components vacuum chucked at the bottom of nozzles disposed on a carriage head, said electronic components are observed by a line-sensor which takes images of the electronic components and based on the images taken by the line-sensor positions of the electronic components are recognized and the electronic components are mounted onto the substrate, said method further comprising the steps of:

• detecting a rotation angle of a jig mounted to said carriage head through recognizing an image of a target formed on the jig with the line-sensor, said jig being transferred above the said line-sensor,
• revising the rotation angle of the jig based on the detected rotation angle by horizontally rotating the jig,
• detecting a rotation angle of said line-sensor through an image recognition by said line-sensor taking an image of a target formed on a jig mounted to said carriage head, said jig of which rotation angle has been compensated being transferred again above said line-sensor to recognize said target on the jig,
• revising said rotation angle of said line-sensor to being across the transferring direction of said carriage head at right angles by horizontally rotating said line-sensor, and
• mounting the electronic components vacuum chucked at the bottoms of the nozzles of said carriage head through observing said electronic components with the line-sensor of which rotation angle has been compensated and recognizing positions of said electronic components based on images taken thereof with said line-sensor.
