When it comes to assembly at workstations, the supplied components are picked manually. In the process, it is almost inevitable that incorrect elements are picked and installed as a result of the routine of the employees. As the complexity and variety of the components being installed increases, the likelihood of incorrectly picked elements also increases.
Poka-yoke workstations also provide a physical barrier (hinged doors) in addition to the visual aids of the classic pick to light system so that incorrect parts cannot be picked even inadvertently.
The employee is guided step by step to the correct component container by the opening of the flaps and the lighting up of the display. The materials required for the working step are picked and there is no need for a long search. Poka-yoke sensors/flaps are also used for material replenishment. This ensures that the correct materials are supplied and installed. The individual working steps can be shown on a display screen.
The benefits of the poka-yoke workstations at a glance:
• Zero defects in assembly
• Productivity is increased considerably
• Process reliability even with multiple product variants
• New employees are trained and productive within a few minutes
• Consistent quality regardless of the employee, no rectification or repair
• No parts lists or instructions on paper
• No searching for components
• Short assembly times
