PURPOSE: A PCB(Printed Circuit Board) movement prevention fixing device of a screen printer is provided to prevent the movement to left and right sides caused by transferring a PCB and to accurately position the PCB at a central position with an identification mark. CONSTITUTION: A PCB movement prevention fixing device of a screen printer comprises a sliding groove, a lateral fixing member(100), an d a pushing rotation fixing member(200). The sliding groove is lengthways recessed downward in a longitudinal direction in the upper part of a center supporting piece(20) symmetrically formed in left and right sides of a center conveyor device(10). The lateral fixing member fixes left and right sides with respect to a progressive direction of a PCB being supplied to the center conveyor device and joined to outer one side under the sliding groove of the center supporting piece so that the PCB is positioned at a central position on a conveyor. The pushing rotation fixing member is joined to left and right sides of the lateral fixing member being joined to the outer side of the center supporting piece of the center conveyor device so that push-fixing and releasing the left and right top surfaces of progressive direction of the PCB being supplied to the center conveyor device. |
