Transfer apparatus for transferring a component of integrated circuitry
View Patent ↗The invention provides for a transfer apparatus for transferring a component of integrated circuitry from a receiving location to a delivery location within an integrated circuitry assembly machine. The transfer apparatus includes a support structure that defines a transfer path between said locations, and a component carrier that defines a receiving zone configured to receive the component of integrated circuitry. The transfer apparatus also includes a retaining mechanism arranged on the component carrier to retain the component of integrated circuitry in position in the receiving zone, the retaining mechanism being operable to release the component at the delivery location, as well as a displacement mechanism engaged with the component carrier to displace the component carrier along said transfer path.
1. An apparatus for transferring a printhead integrated circuit from a receiving location to a delivery location within a printhead assembly machine, the apparatus comprising:
a printhead carrier defining the delivery location, said printhead carrier having a plurality of discrete tortuous ink paths for ducting ink to the printhead integrated circuit;
a support structure that defines a transfer path between said locations;
a carriage that defines a receiving zone configured to receive the printhead integrated circuit;
a retaining mechanism arranged on the carriage to retain the printhead integrated circuit in position in the receiving zone, the retaining mechanism being operable to release the printhead integrated circuit at the delivery location; and
a displacement mechanism engaged with the carriage to displace the carriage along said transfer path.
2. An apparatus as claimed in claim 1 , in which the support structure includes a support arm extending between said receiving and delivery locations such that the transfer path is linear, the displacement mechanism including a linear motor arranged on the support arm.
3. An apparatus as claimed in claim 1 , in which the carriage includes a shuttle plate, the receiving zone being defined by a vacuum plate arranged on the shuttle plate, the retaining mechanism including a gel pack for retaining the printhead integrated circuit.
4. An apparatus as claimed in claim 3 , wherein the carriage includes a vacuum tube arranged in fluid communication with the vacuum plate, said tube arranged in fluid communication with a vacuum pump operable to draw air through apertures defined in the vacuum plate to operatively retain the printhead integrated circuit on said vacuum plate.
5. An apparatus as claimed in claim 1 , in which the displacement mechanism includes a linear motor positioned on the support structure, said linear motor configured to displace the carriage along the transfer path.
