Abstract

Printed wiring boards are separated from each other and a panel by an apparatus operating in a specific sequence. The apparatus is capable of precisely cutting different sized printed wiring boards but all of the printed wiring boards of a panel are the same size. An apparatus 1 (Fig. 1) for cutting a plurality (two shown) of printed wiring boards 2 (Fig. 2) from a panel 3 includes a tooling plate 4 (Fig. 1) having a plurality of air-activated location pins 5 (one shown) mounted thereon at various locations in accordance with the necessity for cutting the printed wiring boards 2 (Fig. 2) precisely. The apparatus 1 (Fig. 1) includes a stationary knife 6 and a movable knife 7. Each cooperating pair of the location pins 5 is located at a precise distance X from the movable knife 7 with this distance being different for each cut.

Apparatus for Precise Separation of Printed Wiring Boards From a Panel

Printed wiring boards are separated from each other and a panel by an apparatus operating in a specific sequence. The apparatus is capable of precisely cutting different sized printed wiring boards but all of the printed wiring boards of a panel are the same size. An apparatus 1 (Fig. 1) for cutting a plurality (two shown) of printed wiring boards 2 (Fig. 2) from a panel 3 includes a tooling plate 4 (Fig. 1) having a plurality of air-activated location pins 5 (one shown) mounted thereon at various locations in accordance with the necessity for cutting the printed wiring boards 2 (Fig. 2) precisely. The apparatus 1 (Fig. 1) includes a stationary knife 6 and a movable knife 7. Each cooperating pair of the location pins 5 is located at a precise distance X from the movable knife 7 with this distance being different for each cut. The panel 3 (Fig. 2) includes a margin 8 extending around the printed wiring boards 2. When cutting the printed wiring boards 2 from the panel 3, the margin 8 is removed from the four sides in four separate cuts by the apparatus 1 (Fig. 1). In the first cut, two of the location pins 5 are activated for disposition within mounting holes 9 (Fig. 2) and 10, which are used to mount the board 2 on a typewriter, in one of the boards 2. Cutting then occurs to remove a portion 11 of the margin 8. After withdrawing the two location pins 5 (Fig. 1) from the mounting holes 9 (Fig. 2) and 10, another pair of the location pins 5 (Fig. 1) is activated for disposition within mounting holes 12 (Fig.
2) and 13, which are used to mount the board 2 on a typewriter, in the other of the two printed wiring boards 2. Cutting then occurs to remove a portion 14 of the margin 8. After the two location pins 5 (Fig. 1) are removed from the mounting holes 12 (Fig. 2) and 13, the panel 3 is shifted so that a p...
