When combined with robot end effectors and peripheral automation equipment, gantry robots can handle various tasks on production lines, such as loading and unloading, workpiece flipping, and workpiece transfer, significantly improving production efficiency, reducing costs, and minimizing accidents by replacing human labor with automated machinery.
[0003] In the field of gantry robots, loading and unloading of robotic arms often occur at the same location. This requires the end effector to have rotation capabilities and be equipped with loading and unloading grippers, as well as a rotating wrist function to achieve workstation transitions at a specific location. With the widespread application of industrial automation, especially in the field of heavy parts where automated production is urgently needed, existing domestic and foreign rotary module products have relatively small load capacities and poor lateral accuracy. The rotation of heavy parts is basically non-standard and customized, resulting in very high costs.
