Bench Top Rubbing Machine
Holmarc Bench top rubbing machine is a compact dedicated machine specially designed for LCD and LCoS R&D Labs. The system is intended for tracing grooves on polyimide surface to orient the liquid crystal molecules. Rubbing Machine, HO-IAD-BTR-02M has been developed with additional features than that of models HO-IAD-BTR-01 & HO-IAD-BTR-02 and an advanced version of HO-IAD-BTR-03. A precise vertical height adjustment in the order of micrometers is possible. It is customized in such a way that, the horizontal stage will be motorized in up and down direction. It will move down when one roll is over and the stage comes back to its initial position for next roll. Hence, rubbing in single direction can be achieved. The substrate movement in linear or vertical is possible at a time.
The substrate along with vacuum chuck is held on a rotation stage so that it can be rotated and positioned at any required angle from ±45 degrees for various rubbing orientations. The substrate can be held either by vacuum or can be mounted on to the additional plate provided with the machine using M4 screws. Maximum size of substrate which can be loaded is 200 mm x 200mm. The system has been developed as a standalone unit in which speed and direction of the spindle can be varied.
Rubbing machine is developed in technical collaboration with Professor Surajit Dhara, School of Physics, University of Hyderabad. his personal website : www.surajitdhara.in
