[0026] Method Step Four, Clamping Process: The piston rod of the clamping cylinder extends. The Y-shaped joint of the clamping cylinder fixed to the piston rod drives the entire clamping jaw component to rotate upward around the axis of the clamping jaw rotating shaft through the clamping jaw connecting rod until the clamping jaw head pushes the ingot into contact with the positioning jaw head and stops after clamping;

[0028] Method Step Six, Long Side Trimming Process: After reaching the trimming station, while keeping the positioning fixture assembly clamping the ingot, the long side of the ingot is trimmed by the long side trimming machine;

[0029] Method Step Seven, Clamping Jaw Return to Horizontal Position Process: After the long side trimming is completed, the piston rod of the clamping cylinder retracts. The Y-shaped joint of the clamping cylinder fixed to the piston rod drives the entire clamping jaw component to rotate downward around the axis of the clamping jaw rotating shaft to the horizontal position through the clamping jaw connecting rod;

[0030] Method Step Eight, Positioning Jaw Return to Horizontal Position Process: The piston rod of the positioning cylinder retracts. The Y-shaped joint of the positioning cylinder fixed to the piston rod drives the entire positioning jaw component to rotate downward around the axis of the positioning jaw rotating shaft to the horizontal position through the positioning jaw connecting rod;

[0031] Method Step Nine, Ingot Output Process: The conveyor transports the ingot forward to leave the ingot positioning station, and the long side trimming of this ingot is completed;

[0032] Method Step Ten, Slide II Return Process: The servo motor II of the lead screw slide assembly II drives the lead screw II to rotate reversely.

[0033] Repeat Method Steps Two to Ten to complete the next cycle of the ingot positioning and clamping feeder.
