Abstract

Printheads are frequently designed to be assembled in one continuous automated process which often includes one or more manual operations. The present embodiment is designed for a completely automated process in which a series of assembly tasks progressively raise the level of the unit. At each level the subassembly is a stable, self-contained unit which may be stored or locally buffered in the assembly process. Fig. 1 shows the first of four assembly tasks. It is seen that stator plate assembly 1, backstop assemblies 2 (only one of which is shown), and printed circuit (PC) board 3, are assembled to produce level #1 subassembly. Notches 4 and holes 5 in PC board 3, and hole 6 in the stator assembly are provided for orientation. (Image Omitted) Fig.
