An insulating glass unit (IGU) assembly line apparatus capable of interleaving double and triple pane IGUs in accordance with an IGU production schedule. Visual indicators or prompts instruct operators at the assembly line in configuring a sequence of IGUs. Triple pane IGUs are assembled with minimal contamination of a center glass lite. A non-contact Bernoulli pad is used to lift a glass lite off from a horizontal or vertical support that conveys it from a glass washer to an assembly station. Each of multiple pads has a capacity to lift approximately seven to ten pounds. Use of multiple pads per glass sheet or lite allows lites having dimensions up to 70 by 100 inches (assuming glass thickness of one quarter inch) to be assembled.

A system and method for vehicle assembly may include a vehicle body sensing unit sensing positions of vehicle bodies conveyed at regular intervals along a vehicle body convey line, a tool sensing unit disposed on a fastening tool for assembling parts to a vehicle body and sensing movement displacement of the fastening tool with respect to an origin of the fastening tool, a tool controller that transmits a fastening torque value of a predetermined part to the fastening tool in accordance with the movement displacement of the fastening tool and records an accumulated value of the movement displacement of the fastening tool, and a main controller that stores a result value of fastening the part, corresponding to a vehicle number of the vehicle body, on the basis of the accumulated value of the movement displacement of the fastening tool and positional information of the vehicle body.
