Reciprocating Platform Runs Automatically
May 3, 2006 |Estimated reading time: Less than a minute
ASTON, Pa. — A reciprocating linear motion platform from Amacoil, Inc. uses a rolling ring drive, which reciprocates automatically without requiring motor reversal. Designed for PCB measurement/cleaning processes, the platform also scans barcodes on parts and other applications requiring repetitive back-and-forth movement of materials.
A control knob on the assembly adjusts to linear speed on-the-fly, without changing motor speed or reducing gears. Mechanical control over speed and travel direction is said to eliminate the need for electronics and programming. Travel length may be increased or decreased using adjustable end stops.
Components are precision-machined to limit vertical and horizontal movement of the platform to within ±0.001". A modified reversal mechanism dampens the action, dissipating forward momentum at the points, and eliminating jarring or jerking.
