J8265 Medical Diagnostics Test Kit Assembly SystemThe Oral Test Device Assembly Machine was designed and built to streamline the manufacturability of a product for a local Medical Device company. The machine’s purpose is to sort, feed and assemble Top and Bottom Housings, Test Strips and Wicks into an Oral Test Device at a rate of 32 parts per minute.
Throughout the part assembly process, components are fed and processed on a Camco Precision Link Indexing Conveyor with custom Delrin fixtures designed to accurately locate and align components within a nest.
From an overall process perspective, operators load plastic bottom housings, top housings and Wicks, from bulk, into the supply hopper of AC driven prefeeders where parts are then fed through a series of conveyors and part manipulating devices which are the key building blocks comprising of a Farason custom sorting and feeding system also referred to as a Farafeeder. Dedicated feeder Fanuc SCARA and six-axis robots, in conjunction with top mounted vision cameras, top lighting and encoder tracking of vision conveyors along with vacuum end of arm tools, picks the components, presented in a single layer, randomly on the conveyor belt, and places them within a conveyor fixture. Throughout the assembly process, the sub-assembly receives in process Keyence vision camera inspections for part presence and location. With all main components loaded, a final Fanuc SCARA robot picks sub-assembled Oral Testers and places them within the nests of Branson Ultrasonic Welders where they are fully welded, assembled and placed back within the fixtures of a Camco Precision Link Indexing Conveyor. Subsequent to completing the assembly, a final component is placed, a part label from a CTM Label Applicator/Placer. A final Keyence vision camera inspection takes place to verify all labels are present and located within the customers specifications. An AB Servo/Pneumatic dual axis pick and place offloads good parts thereby completing the assembly process of the Oral Test Device.
