The Simplimatic team has been hard at work developing a new robotics cell that can visually inspect, pick, and transfer small semiconductors between different types of component carriers. This cell was designed for a global electronics manufacturer to automate the manual process of moving delicate components between different types of JEDEC trays. This pick-and-pace transfer is vital for the customer’s manufacturing process, and has proven to be a unique challenge for the Simplimatic engineering team.
The automation of picking-and-placing is a relatively straight forward process, but the scale of this project has required special programming and vision in order to meet the required accuracy repeatability of +/- 76 microns (0.002”) or a size that is roughly 25 percent thinner than a human hair.
In order to achieve these tight tolerances, this custom robotic automation cell is using Simplimatic’s Cimtrak® edge belt conveyor, a FANUC® LR Mate 200iD, a Basler® camera, and two iRVision cameras.
The transfer process begins when a JEDEC tray enters the cell for initial verification under a front-lit Basler camera. The Basler camera utilizes custom vision software from Simplimatic to determine semiconductor orientation and identification.
The FANUC robot then individually picks the components and moves them to a fixed iRVision camera to verify the exact x and y position of the product on the micron level. The FANUC robot then uses the camera data and a final arm mounted iRVision camera to compute the exact place position for the component based on a three-point positioning algorithm.
This system relies on precision and expert programming, but it will work well to increase our customer’s line throughput, Rick Bottoms, Simplimatic Controls Engineer, said.
After final tray placement the electronics exit the cell for further down-line processing. According to initial reviews, this system is shaping up to be a huge success for the customer and will greatly streamline production after integration.
