ABSTRACT:
An eyeglass lens tinting machine which utilizes a microprocessor-controlled stepping motor to carefully control the vertical oscillations of a support structure including a vertical shaft which mounts a horizontal boom which in turn supports an eyeglass lens holder. The lens holder is moved directly up and down (with substantially no horizontal components of movement) by the mechanism. The base which mounts the vertically sliding shaft which supports the boom also mounts the stepping motor and printed circuit board with the microprocessor controller on it. The tinting machine has two basic modes of operation, the solid tint mode in which the lens is lowered beneath the surface of dye in a dye vat and reciprocated completely immersed for a pre-set period of time to create an even, uniform tint. The other mode is a gradient tint mode which is achieved by lowering the top portions of the eyeglass lenses into the dye vat to the line at which the gradient starts, subsequent to which the machine will simultaneously reciprocate the lenses up and down and slowly withdraw them from the dye so that they are moving vertically at all times, and are being withdrawn from the dye so that upper portions of the lens are immersed for longer periods of time, thus creating a smooth, even gradient.
