Rotary Table Automated Assembly Cell

An automated assembly cell consisting of a rotary table, which carries workpieces through multiple work stations, performs a machining operation on a wire printer printhead.

The figure shows that workpieces are delivered to the assembly cell, in totes, through input port 1 from material handling domain 2 (conveyor belt system) and finished products, and rejects, leave the cell via output ports 3 and 4 to material handling domain 2. Workflow through the cell is buffered by three additional tote positions in each port.

Incoming workpieces are unloaded from totes by robot 5 and loaded into the fixture at workstation #1 of rotary table 6. The table now rotates carrying the workpiece to workstation #2. In station #2 the exact position of the printhead is sensed causing a grinding wheel vertical position to be adjusted accordingly. The tips of the print wires are then ground to the required dimension. Table 6 now rotates carrying the workpiece to workstation #3. This station is identical to station #2 and is provided for backup in case station #2 fails. Table 6 now rotates through station #4 to station #5. Station #4 is unused and provided for possible future expansion of the workscope of this cell. At station #5 the ground printwires are inspected by an optical device and identified as accepted or rejected. Table 6 now rotates to station #6 where the workpiece is unloaded by robot 7 to a tote in the appropriate output port; good pi...
