MCM Direct Printer Random Input

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

This system comprises four basic assemblies:

1. The set-up mechanism (Figs. 1 and 4).

2. Print wheel carrier platform assembly 8.

3. Ink reservoir assembly 1.

4. Ink transfer roller (applicator) assembly 5.

After the set-up is completed, as described below, the apparatus illustrated in Figs. 1, 2 and 3 prints on demand a complete line by pressure of the print wheel arrangement 22 onto the surface of the module 11. The cam 10 drives the print wheel platform 8 towards the module, deposits the image, and returns to its original position. The modules are indexed to the next line, After the module is printed with the required number of lines, the next module is indexed into printing position.

The ink reservoir 1 is attached to the frame assembly 9 and contains a roller for the distribution of ink onto selected print wheels 22. The metering roller 2, mounted on sleeve bearings, is a part of the reservoir assembly 1, driven by a motor. The primary function of this roller is to receive and transfer ink onto distributing roller 5. The doctor blade 3 removes excessive ink from the metering roller to achieve more uniform ink application. The guide rollers 4, mounted on both ends of the distributing roller, are supported by the ink roller rails 6 until the transfer of ink onto selected printing wheels 22 is completed. Detent 7 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 printing wheels 22, mounted on sleeve bearings, are part of the carrier platform assembly
8. This assembly is suspended from both sides by two cam driven arrangements 10, guided by two support bearings...
