Fastening apparatus with authentication system
View Patent ↗The present invention relates to a fastening apparatus for fastening a flexible printed circuit board (PCB) to a printhead assembly. The printhead assembly includes a printhead carrier and an ink ejection printhead carried by the carrier. The fastening apparatus includes a support assembly. An authentication system is arranged on the support assembly and is configured to authenticate the printhead assembly. At least one bonding assembly is configured to bond the PCB to the printhead assembly. A controller is configured to control the bonding assembly to bond the PCB to the printhead assembly subsequent to the authentication of the printhead assembly.
1. A fastening apparatus for fastening a flexible printed circuit board (PCB) to a printhead assembly, the fastening apparatus comprising:
a support assembly defining an internal space for receiving therein the PCB and the printhead assembly;
an authentication system having a scanner for scanning a printhead code provided on the printhead assembly, the scanner being arranged on the support assembly;
a bonding assembly arranged within the internal space of the support assembly, the bonding assembly including one or more heater assemblies for bonding the PCB to the printhead assembly; and
a controller operatively connected to the authentication system and the bonding assembly, the controller for comparing the printhead code scanned by the scanner with a list of authentic codes, and for further controlling the one or more heater assemblies to bond the PCB to the printhead assembly in accordance with a result of the comparison, wherein
the bonding assembly further includes a pneumatic carriage defining a nest in which the printhead assembly is nested, and
the pneumatic carriage includes a pneumatic actuator for moving the nest from outside of the internal space to inside of the internal space.
2. A fastening apparatus as claimed in claim 1 , wherein the authentication system includes an optical scanner configured to scan identification indicia borne by one of the printhead and the printhead carrier.
3. A fastening apparatus as claimed in claim 2 , wherein the optical scanner is configured to scan identification indicia in the form of a barcode.
4. A fastening apparatus as claimed in claim 1 , wherein the scanner is operable to scan a PCB code provided on the PCB, the controller is operable to compare the PCB code with a further list of authentic codes, and the controller controls the heater assembly further in accordance with a result of the comparison of the PCB code with the further list of authentic codes.
5. A fastening apparatus as claimed in claim 1 , wherein the bonding assembly includes a bending mechanism configured to bend the PCB subsequent to bonding the PCB to the printhead of the printhead assembly.
6. A fastening apparatus as claimed in claim 1 , wherein the support assembly includes a visible indicator operatively connected to the controller, which is configured to control the visible indicator in a plurality of different ways to represent corresponding operational conditions of the fastening apparatus.
