One of our medical device clients required an innovative solution for an AI inspection system along with a transfer system to connect several existing machines. In addition, the system was needed to buffer the product to accommodate stoppages in the upstream machines. The system required complete tracking of the product throughout to ensure that any reject detected at the infeed inspection was tracked.
There were a few challenges in the project, one of which was establishing an AI inspection system. SP worked closely with a camera inspection specialist and the camera to create a module that would “teach” itself based on historical and new inspection criteria. Another challenge was handling the delicate and flimsy product.
The infeed inspection system was equipped with an AI deep learning camera that inspected 100% of the product. During inspection, a QR code was recorded, allowing for the tracking of any rejects throughout the process.
The product then entered the customer’s “oven” and, subsequently, the SP handling system. Using specially developed conveyor systems designed to ensure product stability, the items were conveyed to various positions. The first step involved feeding the product through a permanent buffer system. Under normal operating conditions, the product would bypass the buffer and continue through the system.
In the event of a stoppage in the upstream machine’s infeed, the buffer would activate and index vertically to store a defined number of products. Once the upstream machine resumed operation, the buffer would reintroduce the products on a first-in, first-out basis.
The product flow direction was then changed by 90 degrees and elevated gradually to suit the next upstream machine. A second 90-degree transition occurred before the product entered a second buffer system similar to the first. Finally, the product progressed through the customer’s oven for final processing.
