Abstract

A low cost, easily adjusted and secure clinching mechanism for securing the leads of components to a circuit board is described. The figure shows a single lead clinching mechanism; however, a plurality of these units may be mounted in a component insertion machine to clinch a plurality of leads simultaneously. A slider 1 is mounted within slider housing 2. Pneumatic cylinder 3 drives slider 1 to move wiper 4 upwardly to come adjacent a circuit board lead 5. Cylinder 3is anchored at 6 to support housing 7. When wiper 4 reaches its uppermost position with shoulder 10 contacting housing 2 at surface 11 and with the tip 8 of wiper 4 close to surface 9 of the component, the continued upward motion of slider 1 rotates wiper 4 to cause it to bend component lead 5 against the surface 9 and thereby clinch the lead 5.

Component Lead Clinching Mechanism

A low cost, easily adjusted and secure clinching mechanism for securing the leads of components to a circuit board is described. The figure shows a single lead clinching mechanism; however, a plurality of these units may be mounted in a component insertion machine to clinch a plurality of leads simultaneously. A slider 1 is mounted within slider housing 2. Pneumatic cylinder 3 drives slider 1 to move wiper 4 upwardly to come adjacent a circuit board lead 5. Cylinder 3is anchored at 6 to support housing 7. When wiper 4 reaches its uppermost position with shoulder 10 contacting housing 2 at surface 11 and with the tip 8 of wiper 4 close to surface 9 of the component, the continued upward motion of slider 1 rotates wiper 4 to cause it to bend component lead 5 against the surface 9 and thereby clinch the lead 5. The spring 12 returns wiper 4 to its initial position upon retraction of the slider 1 by operation of cylinder 3. As is readily apparent, any number of wiper mechanisms can be mounted in parallel and each can be operated either singly or in unison so that a wide range of component lead locations can be clinched.
