MCM Off Set Printer Random Input

This system enables one to print on MCM (multi-chip module) caps of various kinds, with random identifying information from a keyboard.

As shown in the drawings, ten stepping motors 19 with gears 15 mounted on motor shafts with keys and secured with setscrews in place. The gears 15 engage set-up racks 20 to provide a lateral motion. The printing wheels 22 are mounted on shaft 25 to rotate freely while being engaged by the selected set-up racks 20. Detent 27 is a solenoid-controlled device, locking the printing wheels in place to assure registration of the set-up mechanism for the duration of the cycle. The motion detectors 21 verify the set-up from the keyboard.

The off-set printer, as illustrated in Fig. 2, may be described as follows: The ink reservoir 1 with doctor blade 3 is attached to the set-up drive frame 16 for easy removal, cleaning or repair. The ink distributor roller 17 is mounted on sleeve bearings and supported by the set-up drive assembly frame 9. The ink transfer roller 18 is in contact with distributing roller, lifting off a metered amount of ink and applying to the selected type wheels 22. The doctor blade 3 removes excessive ink deposit from the roller 17. The ink roller 18 moves along the guide rails 24 to assure uniform ink application onto selected type wheels. The motion detectors 21 verify the set-up from the keyboard. The transfer wheel 13 (platen) is mounted on the shaft to rotate, engaging the printing wheels to receive the print image. While the line image is being transferred from the selected printing wheels 22 onto the platen 13 one line at one time, the opposite side of the platen prints the image onto the surface of the module 11. Then it is indexed on line, as shown in Fig. 1. After the required number of...
