[0019] In addition, in the grinding process of the lens performed by the numerical control cutting device 600, the processing time of one lens takes about several minutes.
Therefore, the processed lens is taken out one by one from the conveying tray for processing, the processed processed lens is conveyed back to the original position of the conveying tray, and the next processed lens is carried into the grinding device one by one for processing. , there is a problem of poor efficiency

The present invention relates to a grinding jig for attaching a lens to be processed to a grinding device for grinding the concave surface of a lens to be processed, a dedicated transport tray for transporting the grinding jig, transporting and holding a lens to be processed on a grinding device, etc. A conveying method and conveying device for grinding jigs and the like on a processing device. The grinding jig (1) of the present invention comprises: a mounting portion (2) installed on the chuck of a grinding device, an annular abutting portion (3) that is close to the convex surface (11) of the processed lens (10), and The close-fitting part serves as an opening part, filling and bonding the convex surface of the processed lens close to the close-fitting part, and filling the void part (4) of the bonding substance (7) holding the processed lens. The jig for grinding is suitable for a numerically controlled grinding device. The conveying tray of the present invention includes: an accommodating portion for placing and holding the above-mentioned polishing jig in which the lens to be processed is placed; a through hole through which the jig for lifting and lowering the polishing jig passes; and a protrusion that engages with the notch (54) of the polishing jig. department.
Description
technical field [0001] The present invention relates to a polishing jig for attaching a lens to be processed to a polishing device for concave grinding of a lens to be processed, a pallet for transport dedicated to the polishing jig, and a polishing device for holding a lens to be processed on a processing device such as a polishing device A conveying method and a conveying device using jigs, etc. Background technique [0002] In recent years, so-called progressive multifocal lenses in which a progressive surface is provided on the concave surface side (inner surface side) of eyeglasses have been developed. Such an inner surface progressive multifocal lens can reduce waviness and distortion which are disadvantages of a progressive multifocal lens provided with a progressive surface on the convex side, and can greatly improve optical performance. [0003] The lapping of the spectacle lens to make the concave optical surface of the progressive multifocal lens on the inner sur...
