Abstract: 973,439. Assembling electrical components on circuit boards. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 22, 1961 [Sept. 27, 1960], No. 34022/61. Heading B3A. In a method of inserting electrical components, having two or more parallel projections on one side of a body, into a circuit board the components are fed to a gripping means which grips only the projections at an area between the body and the projection extremities. Component gripping.-Referring to Fig. 4, which shows a component already in position between tongs 22, 24, as control block 56 moves downward pin 60 contacts the top fixed tong 22 and pivots it downward about shaft 18. This in turn moves pusher housing 28 away from pin 69, thus enabling spring 26 to move the lower tong 24 into gripping engagement with the component terminal wires. To facilitate gripping, each tong has longitudinal grooves in which the terminal wires are held. Severing and transfer.-As seen in Fig. 4, a cutter 71 cuts the wires to length as the pin 60 continues to force the tongs downward. At this stage a second rotational actuating means is initiated, i.e. rod 44 is moved downward and, through coupling to collar 20 on tong housing 17, continues to rotate the tongs until the position shown in Fig. 6 is reached. Component insertion and release.-Referring to Fig. 6, the control block 56 is now caused to move upward and its upper pin 59 operates rocker arm 37 which moves the pressing rod 27 downward, thus forcing the component wires between the gripping jaws into holes 100 in a plate 101. Next, cam 58 on the control block 56 contacts pin 47 and causes arm 46 to move clockwise about pivot 45 simultaneously depressing the movable jaw 24 through the pin 48 and displacing the tong body 17 clockwise by it being contacted by roller 50. Thus, as seen in Fig. 7, the component is released. Return to commencement of cycle.-This phase is substantially a reversal of the two previous phases, resulting in a return to the position shown in Fig. 4.  Component feed to tongs.-Referring now to Fig. 11, components mounted on tape are fed to a wheel 72 along the chain dotted line in the direction indicated.
