Jig for polishing the edge of a thin solid state array panel

摘要

A jig for polishing a end of a thin solid state imaging panel on a horizontal rotating polishing surface is composed of a supporting ring structure, a panel holder and a panel mount. The supporting ring structure is composed of a supporting ring with a polished bottom surface and two slide guides extending vertically from the top of the ring. The panel holder is composed of two slide bearings adapted to accept the two slide guides on the supporting ring and a planar mounting surface. The panel holder is mounted on the supporting ring structure so that the slide guides and the slide bearings co-operate to support the panel holder on the ring in a plane perpendicular to the rotating polishing surface to permit the panel holder to move linearly under gravity in a vertical direction from a raised position where a polished bottom end of the panel holder is not in contact with the polishing surface, to a second position where the bottom end is in contact with the polishing surface. The panel mount secures the panel to the panel holder during the polishing operation. In operation, a solid state imaging panel is rigidly mounted to the panel holder in such a way that the panel protrudes down from the panel holder a preset distance. This panel holder is mounted on the ring structure of the polishing jig and the jig is placed on the surface of the rotating polishing wheel. As the glass is polished, the protruding panel and panel holder slowly lower by gravity to maintain contact with the polishing wheel surface. When the protruding section of the panel has been polished even with the polished bottom end of the panel holder, the polishing rate slows significantly and the process is complete.
