of information to be displayed in real-time so each component can be checked visually for presence, positioning, orientation, part-marking, polarity and many other parameters. Boards that pass the inspection then progress for soldering. If there is any discrepancy between the board and the BOM, the soſtware can save a high-resolution copy of the component image to a shared folder for Norcott’s team of engineers to validate.


RNA AUTOMATION www.rnaautomation.com Carpet gap hider ‘Poka-Yoke’ inspection station


RNA has designed and built a bespoke workstation, applying Poka-Yoke (also called mistake proofing) requirements to prevent the human errors that result in product defects. Poka-Yoke is a quality assurance technique intended to eliminate product defects by preventing, correcting or drawing attention to human errors as they occur. Its objective is to achieve zero defects. The workstation was designed to ensure the application of the correct label to the correct carpet gap hider product, since there are two types of product that are very similar to each other, both in size and in colour. Manual execution of the task required a high concentration from the worker, and was the cause of many errors,


The workstation frame features a Poka-Yoke clamp and a Poka-Yoke vision sensor, Carpet gap hider workstation


part presence sensing and a scanner and printer as well as an HMI and system control. The operator loads the LH or RH Carpet Gap Hider into the formed nest and activates the component locking clamps. At the start of each batch, the operator will scan the barcode that indicates the correct product colour for that particular batch (batch size can vary). The vision sensor checks the product and if it is correct, the machine will print off the correct label. The operator can then lower a mechanical guide onto the component to allow the operator to apply the label in the correct position on the component. The clamps will be released and the part can be removed from the fixture ready to load the next component. If the product does not match the build requirements the clamps will remain locked and the HMI will request a supervisor to attend. The Poka-Yoke designed workstation helps workers to be ‘right first time’, enhancing the quality and overall output of the process.
