In the laptop panel production process, customers need to pick up panels from the feeder to the machine for processing, and the processed panels for unloading, through the composite robot for transfer between workstations, and the processing site environment is too small to be scanned inside the equipment. In order to realise the flexibility of the multi-category processing capability of the processing line, and to reduce the cost of deploying customised fixtures and limit devices, the customer chooses a small, lightweight 3D vision system to complete the efficient loading and unloading of workpieces, and to realise efficiency and cost reduction.
