<p>PURPOSE:To conduct drives of each part with high accuracy as well as to meet a change of application very easily by driving engagement and disengagement of a feeding mechanism which reciprocates freely in a carrying direction and an in-and-out of a positioning pin with using an electromagnet. CONSTITUTION:A heater brock 145 goes up and down as an arrow 151, a snap-in lid 133 goes up an down as an arrow 152, a positioning pin 76 moves as an arrow 153, a feed engaging slider 83 as an arrow 154 and an engaging bar 111 as an arrow 155. All of these things except the engaging bar 111 are controlled by increase and decrease of power of an electromagnet. The heater brock 145 rises to an upper limit stopper position and is pressed against a lower surface of a lead frame 1. The snap-in lid 133 is pressed against an upper surface of the lead frame 1. The positioning pin 76 is inserted in a positioning hole 1a. Namely the heater brock 145, the snap-in lid 133 and the positioning pin 76 position the lead frame 1 thereby performing an operation of bonding in a fixed state.</p> |
