Manual Workstations
Even where manual assembly is required, there is always a need for error proofing. Pictured is an example of a manual workstation that utilizes sensors to verify that the correct parts are assembled and that the job was done in the correct order. These mini light curtains are located at the ends of the conveyors so that when the operator reaches in to get a part it breaks the beam and tells the control which part was taken. Each conveyor also has a light that prompts the operator as to the correct part for a given assembly. If the process is not done in the correct order an audible alarm will sound. The manual nut driver also has torque feedback to tell the controls system that proper torque has been achieved.
