Abstract

An assembly tool is described which properly aligns magnetic head suspensions in strip form and the magnetic head sliders so that the sliders can be bonded to the suspensions within the required close tolerances. The magnetic head suspensions comprise a sheet metal part formed so that a plurality of suspensions 1 are contained in a continuous strip 2. The plurality of suspensions 1 are bonded to the slider 3 and then separated into individual finished magnetic head suspensions. The suspensions include a first tooling hole 4 and a second tooling hole 5 which serve to properly align the suspensions during the assembly operation. The assembly tool comprises a plurality of assembly stations 6 equal to the number of suspensions 1 in a single continuous strip.

Sliders/Suspensions Automatic Alignment and Bonding of the Strip Form

An assembly tool is described which properly aligns magnetic head suspensions in strip form and the magnetic head sliders so that the sliders can be bonded to the suspensions within the required close tolerances. The magnetic head suspensions comprise a sheet metal part formed so that a plurality of suspensions 1 are contained in a continuous strip 2. The plurality of suspensions 1 are bonded to the slider 3 and then separated into individual finished magnetic head suspensions. The suspensions include a first tooling hole 4 and a second tooling hole 5 which serve to properly align the suspensions during the assembly operation. The assembly tool comprises a plurality of assembly stations 6 equal to the number of suspensions 1 in a single continuous strip. One of the assembly stations 6m near the middle of the strip is fixed in position, and all the other assembly stations 6 are mounted so that a limited lateral movement can be accommodated. The floating nature of the assembly stations is necessitated by the practical problem that the suspensions in strip form cannot be produced to a close tolerance throughout the strip without excessive cost.
