CONSTITUTION: A gripper for a surface mounter comprises a gripper holder(10) which has an air hole at a center thereof, a gripper adapter(12) which is coupled to a lower portion of the gripper holder and has a fixing hole(30) at a side thereof, a gripper piston rod which is mounted through a center of the gripper adapter in an inside of the gripper holder to be moved upward and downward by air supplied from the air hole, a pair of jaws which are movably disposed at the inside of the gripper adapter and have a fixing bar at one side thereof, a gripper tooth adapter(18) which is fixed on an upper portion of the jaw by a fixing member(34), a gripper tooth(20) which is fixed on an upper portion of the gripper tooth adapter by the fixing member to hold an electron component, a shaft(22) which is disposed between the jaws which are symmetrically disposed and fixed to an end of the gripper piston rod, a cam(28) which is coupled to both ends of the shaft, and a roller(24) which is coupled to both ends of the shaft to be contacted to an outside of the cam.
