Since the products are mainly supplied in bulk, vibratory feeder loading requires front and back inspection and correction, and only one material can be picked up per loading cycle. A UPH of 6000 is needed while picking up only one material at a time. The existing method uses electric cylinder modules to build a 2-axis (or 3-axis) conveying mechanism to complete the loading action by picking up and placing product parts. However, commonly used 2-axis (or 3-axis) conveying mechanisms have a cycle time of 4 seconds, and with one material picked up at a time, the UPH only reaches 900.
