Description
Technical field
The present invention relates to a kind of pad printer of in progressive multi-focal lenses eyeglass manufacture process, using, detailed says, thereby is a kind ofly can show the permanent hidden mark on the progressive multi-focal lenses eyeglass and utilize it that eyeglass is positioned the accurately eyeglass pad printer of printed ink mark.
Background technology
Pad printer is mainly used in progressive multi-focal lenses eyeglass manufacture process and prints interim ink indicia on eyeglass, interim ink indicia has shown the position of several main reference points that position when being used to measure with cut edge on the eyeglass, promptly is removed after the eyeglass manufacturing is finished.
The location of eyeglass in the pad printer supporting is extremely important, and Fig. 1 is the schematic diagram of a kind of interim ink indicia pattern of progressive multi-focal lenses eyeglass, and Fig. 2 is the schematic diagram of a kind of permanent hidden mark pattern of progressive multi-focal lenses eyeglass.As Fig. 1 and shown in Figure 2, two reference markers 3 that align in the permanent hidden mark pattern of mint-mark are concentric in the interim ink indicia pattern that must guarantee to be printed two alignment circle of references 2 and the eyeglass 1, the ink indicia of being printed like this is the machining information of reflection eyeglass accurately, thereby guarantees the accuracy of subsequent technique.
Permanent hidden mark be a kind of by engraving technology in the small mint-mark that lens surface stays, be sightless in the ordinary course of things, have only by special method or by special instrument and just can see.When using conventional pad printer to print interim ink indicia, the operator at first needs to use special method or seeks two alignment reference markers 3 in the permanent marks pattern on the eyeglass by special instrument, use felt tip pen two points of point on the lens surface at reference marker place then, and utilize these two eyeglasses of naming a person for a particular job in the supporting of pad printer, to position, begin the bat printing process again.This method is not only loaded down with trivial details, and because inevitably there is parallax in operator's observation, its degree of accuracy is also relatively poor.
The external pad printer that printed ink mark on the progressive multi-focal lenses eyeglass occurred being applicable to, it is except basic tampon pad printing system, also comprise an optical system that can show the permanent marks on the eyeglass, position by permanent marks on the observation display reach the auxiliary lens location purpose (refer to Patent Document: United States Patent (USP), US7324190).But the employed device of its optical system is more, has comprised light source, beam splitter, collimation lens, imaging apparatus and micro-prism array etc., and not only structure is comparatively complicated, and cost is also higher.
Summary of the invention
For the eyeglass pad printer that solves prior art deficiency at some technical elements, the present invention has done improvement to the eyeglass pad printer, a kind of permanent hidden mark that can show on the progressive multi-focal lenses eyeglass is provided, the operator can be positioned, on eyeglass, accurately to print the eyeglass pad printer of interim ink indicia according to shown mark to eyeglass.
The present invention is achieved through the following technical solutions:
The present invention is a kind of eyeglass pad printer with visual hidden mark, comprise eyeglass supporting, frame, glue head, lubricating cup and forme, also comprise optical system, optical system comprises background maker, imaging apparatus and display, and background maker and imaging apparatus lay respectively at the both sides of eyeglass supporting.
Eyeglass supporting of the present invention is connected by attaching parts and frame are removable with forme, and attaching parts comprise slide rail that is fixed on the frame and the slide block that is individually fixed on eyeglass supporting and the forme, and the glue head can move up and down with frame and be connected.
Background maker of the present invention comprises at least one light source and a light diffuser.
Background maker of the present invention is the light diffuse reflective structure that the light diffuse transmission structure of light source and the eyeglass both sides that lay respectively at light diffuser or light source and eyeglass are positioned at the homonymy of light diffuser.
Be intensively distributed with the diffusion unit of small size in the diffusion area of light diffuser of the present invention, the transmissivity of per two adjacent diffusion unit or reflectivity exist than big-difference.Light diffuser is that the scraps of paper, plank, plastic sheet, frosted glass or other have the device of rough surface, is printed on it or is carved with light and shade pattern at interval, and light source is white light source or monochromatic light light source.
Background maker of the present invention comprises a panel and a plurality of small light sources that separate that are installed on the panel.
Background maker of the present invention is a display screen, shows light and dark background pattern on the display screen.
The invention has the beneficial effects as follows, can show transparency, the permanent hidden mark on the progressive multi-focal lenses eyeglass of dyeing, photochromic and other kind, the operator can be positioned eyeglass according to shown mark, to have improved the convenience and the degree of accuracy of location progressive multi-focal lenses eyeglass on pad printer in the eyeglass pad printer of accurately printing interim ink indicia on the eyeglass, employed optical system structure is simple, and is easy to operate, cost is low.
