System and method for print head alignment using alignment adapter
View Patent ↗Systems and methods for pre-aligning print head(s) to alignment adapter(s) to increase print resolution of printed matter, and to reduce offline time of a printing system due to print head alignment, include the use of an alignment adapter to which a print head is pre-aligned and which includes precision alignment features which precisely engage cooperating precision alignment features on the print head carriage mounting plate of the print head carriage. Print head(s) can be pre-aligned and fine-tuned to alignment adapter(s) even while the printing system is still in print production. Pre-aligned print head/alignment adapter assemblies can then be quickly mounted on the print head carriage using the cooperating precision alignment features of the adapter and print head carriage mounting plate. Duplicate sets of print head mounting sockets can include print heads aligned at different relative offsets (e.g., half a pixel) to increase the print resolution.
1. A print head alignment adapter comprising:
an alignment adapter body configured for mounting thereon a print head, the print head comprising a plurality of nozzles and a housing configured with a nozzle aperture through which the plurality of nozzles are exposed for ejecting ink during printing, the alignment adapter body comprising
an alignment adapter aperture sized to allow at least one of spatial position adjustment and angular rotation adjustment of the print head when the alignment adapter is mounted to the alignment adapter body, and
a plurality of precision mounting features which align with and engage cooperating precision mounting features of a print head carriage of a printing system in which the print heads are to be mounted, wherein, when the plurality of precision mounting features are respectively engaged with the cooperating precision mounting features of the print head carriage, precisely align the print head alignment adapter relative to the print head carriage;
wherein the precision mounting features and corresponding cooperating precision mounting features comprises at least one of quasi-kinematic coupling components and kinematic coupling components.
2. The print head alignment adapter of claim 1 , wherein the print head is mounted on the alignment adapter body and aligned to features of the alignment adapter to form an aligned print head assembly.
3. The print head alignment adapter of claim 2 , wherein the aligned print head assembly is mounted on the print head carriage through engagement of the precision mounting features of the alignment adapter and the corresponding cooperating precision mounting features of the print head carriage.
