Description

Viracon, a leading glass fabrication company, has submitted a project request to MNSU, Mankato to create a new warp inspection system for their glass. The principal objective of this project was to develop a process, which measured the warp in heat treated glass. Warp was defined as bending of glass. The company currently uses an inspection process that was slow, unreliable and required multiple employees to record the measurement. To meet ASTM standards Viracon must produce glass with less than 1/32” of warp per linear foot. Excessive glass warp can also cause problems throughout the manufacturing process. An automated inspection process has been designed, which measures the warp of each pane of glass, within the tolerance limit, in a non-bias and reliable process. The design consists of a constructed mock assembly line equipped with neoprene wrapped rollers to mimic the assembly lines used at Viracon. Position sensors, a data acquisition (DAQ) system and a LabVIEW program were used to calculate the warp on each pane of glass. Research and sensitivity tests were performed to select the most appropriate position sensor and DAQ system. This design, upon its completion, would be able to measure the warp for a glass size of ¼” X 24” X 36” and could be configured for other glass sizes. The new design is faster, more accurate, and requires less employees than Viracon's current warp measurement process.
