Abstract
Systems, methods, and software for fabricating a printhead. In one embodiment, a system comprises at least one punch press configured to punch first nozzle holes in a first nozzle plate with a first punch, where each of the first nozzle holes includes a first converging section, and to punch second nozzle holes in a second nozzle plate with a second punch, where each of the second nozzle holes includes a second converging section. The system further comprises a bonding tool configured to bond the first nozzle plate to the second nozzle plate to form a nozzle plate stack, where the first nozzle holes and the second nozzle holes define nozzles of the printhead.
Claims20
A method of fabricating a printhead, the method comprising:
- punching first nozzle holes in a first nozzle plate with a first punch of at least one punch press, wherein each of the first nozzle holes includes a first converging section;
- punching second nozzle holes in a second nozzle plate with a second punch of the at least one punch press, wherein each of the second nozzle holes includes a second converging section;
- and
- bonding the first nozzle plate to the second nozzle plate with a bonding tool to form a nozzle plate stack, wherein the first nozzle holes and the second nozzle holes define nozzles of the printhead.
A fabrication system for a printhead, the fabrication system comprising:
- at least one punch press configured to punch first nozzle holes in a first nozzle plate with a first punch, wherein each of the first nozzle holes includes a first converging section;
- the at least one punch press is further configured to punch second nozzle holes in a second nozzle plate with a second punch, wherein each of the second nozzle holes includes a second converging section;
- and
- a bonding tool configured to bond the first nozzle plate to the second nozzle plate to form a nozzle plate stack, wherein the first nozzle holes and the second nozzle holes define nozzles of the printhead.
A non-transitory computer readable medium embodying programmed instructions executed by a processor, wherein the instructions direct the processor to implement a method of fabricating a printhead, the method comprising:
- controlling at least one punch press to punch first nozzle holes in a first nozzle plate with a first punch, wherein each of the first nozzle holes includes a first converging section;
- controlling the at least one punch press to punch second nozzle holes in a second nozzle plate with a second punch, wherein each of the second nozzle holes includes a second converging section;
- and
- controlling a bonding tool to bond the first nozzle plate and the second nozzle plate to form a nozzle plate stack, wherein the first nozzle holes and the second nozzle holes define nozzles of the printhead.
