Patent ID: 8296937

Claim:
An assembler for constructing a pagewidth inkjet printhead by assembling a plurality of inkjet printhead integrated circuits (ICs) on a carrier, said assembler comprising: a support assembly operatively supporting a diced wafer, said diced wafer including the printhead ICs; a wafer positioning assembly for positioning the diced wafer; a die picking assembly for picking the printhead ICs from said wafer; a die placement assembly for placing the printhead ICs onto the carrier such that a predetermined plurality of printhead ICs are sequentially positioned across the carrier so as to construct said pagewidth inkjet printhead, wherein the carrier defines a plurality of tortuous ink paths for supplying ink to fluid inlets in each printhead IC; a die conveyance mechanism for operatively conveying the printhead ICs from the die picking and placement assemblies; a clamp assembly comprising: an elongate clamp body shaped and configured to be received by the die placement assembly; a pair of elongate retaining plates mounted on top of the body; an insert shaped and dimensioned to be received in the body below the plates, the insert operatively receiving said carrier; and a diaphragm positioned in the body, the diaphragm being pneumatically displaceable to operatively urge the insert against the retaining plates; and a control system controlling the assembler, wherein said wafer positioning assembly comprises: a displacement assembly having a base plate, the base plate having first and second stages mounted thereon; and a wafer support plate assembly rotatably mounted on the second stage, the support plate assembly configured to receive the wafer and having a motor under control of the control system to rotate the support plate assembly underneath the die picking assembly.
