Abstract
The system disclosed herein is a high speed method and apparatus for presenting parts to a laser beam for marking the parts. The apparatus is capable of feeding at adjustable rates, various sizes and configuration of parts in strip form such as electronic component, a die cut strip or on lead frames.
Claims6
A strip feed and marking machine comprising,
- a frame 10,
- a guide rail,
- slidable means supporting said guide rail on said frame and adapted to carry strips 22 of electrical components,
- a laser 29 on said frame,
- means on said machine to move said strips 14, 16 along said guide rail,
- an electric eye and a light source 27,
- means slidably supporting said electric eye and said light source 27 on said frame,
- whereby light from said source 27 to said electric eye is adapted to be intercepted by the leading edges of said electrical components 30,
- said electric eye being connected to said laser 29 to trigger said laser when a leading edge of a said component intercepts said light from said light source to said electric eye whereby said laser is triggered and marks a said electric component,
- and first micrometer means 19 connecting said guide rail to said frame for moving said guide rail in a first direction relative to said frame,
- a second micrometer means 20 connected to said frame and to said means slidably supporting said electric eye to adjust the position of said electric eye and light source relative to said frame in a said first direction and a third micrometer means 13 connected to said frame and to said means supporting said electric eye to adjust the position of said electric eye and light in a second direction relative to said frame.
