Abstract

In a semi-automatic card assembly tool, a card, onto which discrete components are to be mounted, is located in a frame 1 carried by the main working surface of the tool. An optical projection device 2 is mounted on the tool to overlie the frame without obstructing the operator's access to the frame and, under programmed processor control, indicates visually on the surface of the card in the frame exactly where the next discrete component is to be inserted by hand. The component's pins extend through the card, from the upper surface thereof, and are cliched by having their ends, which extend through the card bent by the clinch attachment while the operator's hand retains it in position, so that, when the card is subsequently removed for flow soldering, for example, the components do not become wholly or partially dislodged.

Semi-Automatic Card Assembly Tool With Clinch Attachment

In a semi-automatic card assembly tool, a card, onto which discrete components are to be mounted, is located in a frame 1 carried by the main working surface of the tool. An optical projection device 2 is mounted on the tool to overlie the frame without obstructing the operator's access to the frame and, under programmed processor control, indicates visually on the surface of the card in the frame exactly where the next discrete component is to be inserted by hand. The component's pins extend through the card, from the upper surface thereof, and are cliched by having their ends, which extend through the card bent by the clinch attachment while the operator's hand retains it in position, so that, when the card is subsequently removed for flow soldering, for example, the components do not become wholly or partially dislodged. The clinch attachment is actuated by the foot of the operator by means of a foot switch 3. The clinch attachment comprises a matrix plate 4, mounted in the lower levels of the frame so as to be able to slide therein in a plane parallel to the card in the frame. Clinch elements 5 are precisely positioned in the matrix plate, also under the direction of the optical projector, in positions which will correspond to those at which components will be inserted. The matrix plate is driven by a compressed air piston and cylinder 6, the air coming from a compressed air source 7 via a solenoid-oper...
