Abstract
An apparatus for transferring a plurality of electronic components includes a row of pick heads operative to pick up the electronic components simultaneously from a first location and to place them at a second location. Additionally, there is a driving mechanism operative to drive the pick heads to move relative to one another in directions which are parallel to a length of the row of pick heads whereby to adjust a pitch width of the pick heads.
Claims7
An apparatus for transferring a plurality of electronic components, comprising a row of pick heads operative to pick up the electronic components simultaneously from a first location and to place them at a second location, and a driving mechanism operative to drive each of the pick heads to move relative to one another in directions which are parallel to a length of the row of pick heads whereby to adjust a pitch width of the pick heads;
- a pulley system comprising a pair of pulleys, each pulley having two or more concentrically-arranged graduated steps of different diameters;
- two or more belts separately connected to respective ones of the graduated steps of the pair of pulleys so that each of the belts has a different pulley ratio relative to another belt;
- and
- wherein at least one pick head is mounted onto each belt.
