Inkjet print heads alignment assembly, kits and methods

摘要

The disclosure relates to assemblies, kits and methods for alignment of inkjet print heads. More particularly, the disclosure relates to assemblies, kits and methods facilitating the alignment of inkjet printheads by selectably modulating the printheads' phase, registration, and yaw relative to the printing direction and optionally, with respect to an additional printhead or printheads.

主权项

1. An assembly for aligning printheads comprising:
a. a mounting platform having a front stage, a back stage and a pair of side rails connecting the front and back stages, the mounting platform comprising at least two linear phase actuators and defining an internal quadrilateral space, wherein each of the front stage and back stage each comprises a pair of parallel tetragonal recesses, each recess pair defining a top opening; b. a carriage operably coupled to the mounting platform, further comprising a phase translation anchor and a registration actuator; c. a sled, nested within—and operably coupled to, the carriage; and d. an inkjet printhead, operably coupled to the sled, wherein the front stage recess further defines a front opening, and the back stage recess defines a rear opening, the assembly is configured to provide three degrees of freedom (DOF) alignment to the printhead relative to the printing direction and optionally with respect to a second printhead.
