Workpiece ejecting system for use in stamping machine

A workpiece ejecting system for use in a stamping machine comprising:

• (a) a die platen (10) linked to a punch (110) and having a die cavity (111) for holding a workpiece to be ejected therefrom;
• (b) a picker (20) vertically aligned with the die cavity (111) on the die platen (10), wherein the die cavity (111) has the shaped of the workpiece and is adaptable to hold the workpiece, and the workpiece is held by using a vacuum system;
• (c) a linear guide bushing (30) in vertical alignment with the picker (20) to guide the picker (20) in either an upward movement or a downward movement;
• (d) a floating base (40) being used for mounting the linear guide bushing (30);
• (e) a linear actuator (70) which is located underneath of a spring plunger mechanism and generates a vertical movement against the spring plunger mechanism;
• (f) a linear guide shaft (50) having two ends and vertically slide along with the linear guide bushing (30) while guiding the picker (20);
• (g) a spring cap (60) connected to the linear guide shaft (50) for restricting a maximum travel of the linear guide shaft (50) vertically and for holding a loaded spring (80) of the spring plunger mechanism in the linear guide shaft (50), wherein the load spring (80) is vertically aligned to the linear guide shaft (50), the linear guide bushing (30) and the picker (20) to hold the picker (20) to be seated on the floating base (40) and to accelerate the downward movement of the picker (20);
• and
• (h) a positioning sensor (90) integrated with the linear actuator (70) for triggering the vertical movement of the linear actuator (70) and the spring plunger mechanism, respectively, thereby the workpiece is moved from the die cavity (111) to the picker, and is then, with an outsource stage for transferring to a packaging machine to pack the workpiece.
