Assembly Line

Description

This use case consists in an assembly line that produces self-closing concealed cabinet hinges. The assembly line includes 19 workstations, each performing specific tasks (e.g., pick and place, screw tightening, riveting) to assemble the components of the self-closing concealed cabinet hinge. These components are shown in Figure 1 and listed in Table 1. The sequence of operations is detailed in Table 2, indicating the input components and the workstation responsible for each operation. Work-in-progress hinges are moved along the line on a pallet.
