Washing machine counterweights are made of concrete and are relatively heavy, making manual handling and loading time-consuming and labor-intensive. In addition, different production plans require multiple counterweight specifications to be loaded in batches at the same workstation. The customer therefore needed an automation upgrade. By deploying a 3D vision system, the customer guides robots to handle and depalletize the counterweights. Fast template switching enables multiple counterweight models to be processed at the same workstation, ensuring line efficiency, improving equipment utilization, and reducing production costs.
