Due to the large number of workpieces, it is necessary to put the next workpiece into the stamping equipment after the stamping of one workpiece is completed. Even if a robotic arm is used for loading, the machine needs to be stopped for loading after the workpieces in the stacking position are taken out. This will cause the stamping work to be interrupted and affect the stamping efficiency of the workpieces. Utility Model Content
