Abstract:
1. A jig set for grinding comprising a set of jig units used for a series of processing from allocation of objects to be ground on a grinding jig (a master plate) through removing the ground objects from the grinding jig after the grinding operation, wherein the jig units comprise: small allocation trays capable of mounting objects to be ground thereon divided in specified partial patterns, after receiving transfer thereof from the surface of a starting tray, on which the objects to be ground are aligned in a specified mounting pattern; a dividing tray having a configuration corresponding to the starting tray, which is capable of holding the small allocation trays previously arranged so that entire aggregation of said partial patterns may be the same as said mounting pattern, when said objects to be ground are transferred to the small allocation trays, and by which said objects to be ground can be transferred from the starting tray to the small allocation trays, while retaining the state of the small allocation trays held therein; a dividing plate which is capable of having the small allocation trays mounted on the surface thereof in the specified arrangement pattern after receiving transfer of the small allocation trays from the dividing tray in which the small allocation trays are retained, and transferring the objects to be ground laid on the small allocation trays onto the surface of the grinding jig in the transferred state; and small removing trays onto which the ground objects are relocated from the surface of the grinding jig in the transferred state and divided into the above-described partial patterns, after completing the grinding of the objects arranged on the grinding jig in the transferred state and after these objects, which were allocated on the surface of the above-described dividing plate in the above-described allocation patterns, have been removed from the surface of the grinding jig by means of a prescribed removing treatment, the combination of the jig units ensuring that all of the objects to be ground are allocated onto the grinding jig at one time without coming into contact with each other and that the ground objects after completion of the grinding operation are removed from the grinding jig.
