Abstract

This article describes a vertical universal chip placement head for replacing horizontal rotary heads. A common problem with existing horizontal rotary heads is that the area consumed is large and is dependent upon the area to be covered by the placement. As the area of substrating increases, the diameter of the head upon the area to be covered by the placement. As the itself must also increase. Thus, the utilization of a vertical head and its fairly simple drive mechanism make setup, operation, and maintenance very efficient, and a relatively small multi-head tool size is accomplished.

Universal Chip Placement Head

This article describes a vertical universal chip placement head for replacing horizontal rotary heads. A common problem with existing horizontal rotary heads is that the area consumed is large and is dependent upon the area to be covered by the placement. As the area of substrating increases, the diameter of the head upon the area to be covered by the placement. As the itself must also increase. Thus, the utilization of a vertical head and its fairly simple drive mechanism make setup, operation, and maintenance very efficient, and a relatively small multi- head tool size is accomplished.

The vertical head shown in the unit has a simple position up and down motion on a slide table 20 with a small vertical spider 10 mounted on a Geneva mechanism 11 carried by a stand 12. The vertical spider 10 has a multiplicity of pick-up stations 13 mounted around the perimeter thereof. A track 14 carrying chips 15 is located adjacent the pick-up head and arranged so that each pick-up 13 will come into proximity to a chip in the track and can pick up a chip from the track. The chips so lifted from the track, by a slight upward motion of slide table 20 and the Geneva unit 11, are then rotated to a 12 o'clock position as the pick- up station 13 is slightly extended so that the chip 15a is positioned and selectively aligned by an orienter 16, also carried on the pedestal 12. Once the chip is aligned at the inverted orienter 16, the pick up station and the Geneva movement 11 are withdrawn to their central position and another rotation of the head takes place. Simultaneously, a new chip is picked up and transferr...
