Abstract

In order to solve the problem of the operator not being able to verify the exact mechanical location of an exposure head with the specific coordinates and not knowing the exact image processing time, a counter and timer have been incorporated into a system for making image artworks for logic cards and boards.

Image X-Y Plotter Diagnostic Counter and Timer

In order to solve the problem of the operator not being able to verify the exact mechanical location of an exposure head with the specific coordinates and not knowing the exact image processing time, a counter and timer have been incorporated into a system for making image artworks for logic cards and boards.

The system includes a plotter, table and exposure head. The input for the images comes from a computer used in the engineering design system (EDS). The image X-Y Plotter Diagnostic Counter and Timer was designed so it could be attached to the plotter for checking the exact location of the exposure head by counting the X-Y motor impulses generated in the plotter.

There are two sets of counters 10 (Fig. 1) and readouts 20 for displaying the exact location of the X and Y motors. The plotter is driven by X and Y stepper motors. The control furnishes four level signals (two for each motor): one for motor direction which causes the counter to add or subtract, and one for motor impulses that indicates movements by .0001 inch. Each counter is comprised of six modules with the readout drivers and associated gating logic. At the zero positions of the X-Y motors, the counters are cleared and read 00.0000. The maximum travel of each motor is 30 inches. The elapsed timer 30 (Fig. 2) reads the accumulated time for each job and is displayed in hours and tenths of hours.

Timer 30 is controlled by relay 26 which is energized by...
