Abstract

An automated assembly cell consisting of a rotary table composed of multiple independently rotatable workpiece fixture units, which carries workpieces through multiple workstations, performs a machining operation on a wire printer printhead. The figure shows that the workpieces are delivered to the assembly cell, in totes, through input port 1 from material handling domain 2 (conveyor belt system) and that finished products and rejects, leave the cell via output ports 3 and 4, respectively to material-handling domain 2. Workflow through the cell is buffered by three additional tote positions in each port. Incoming workpieces (printheads) are unloaded from totes at input port 1 by robot 5 and loaded into the fixture at workstation #1 of rotary table 6.

Rotary Table Automated Assembly Cell With Multiple Rotary Fixture Units

An automated assembly cell consisting of a rotary table composed of multiple independently rotatable workpiece fixture units, which carries workpieces through multiple workstations, performs a machining operation on a wire printer printhead. The figure shows that the workpieces are delivered to the assembly cell, in totes, through input port 1 from material handling domain 2 (conveyor belt system) and that finished products and rejects, leave the cell via output ports 3 and 4, respectively to material-handling domain 2. Workflow through the cell is buffered by three additional tote positions in each port. Incoming workpieces (printheads) are unloaded from totes at input port 1 by robot 5 and loaded into the fixture at workstation #1 of rotary table 6. It is seen that rotary table 6 carries six workpiece fixtures corresponding to surrounding workstations #1 to #6. Each of the six fixtures is mounted on an independently rotatable sub-unit of rotary table 6. After the fixture at workstation #1 is loaded, table 6 rotates, carrying the workpiece to station #2. In station #2, the fixture rotates to precisely orient the printhead for the following operation. Fixture rotation is controlled by an optical system. Following orientation, table 6 advances the workpiece to station #3 where an endmill makes a rough-cut slot in the printhead spring plate. Table 6 then advances the piece to station #4 where a...
