In Fig. 1 to Fig. 4, the corresponding relation of component names and Reference numeral is:
The specific embodiment
Core of the present utility model is held device and a kind of edge polisher for providing a kind of eyeglass to add, this edge polisher is equipped with this eyeglass and adds and hold device, in the utility model, this eyeglass adds holds device by its structural design, can realize improving eyeglass and add the purpose of accuracy of alignment in the process of holding centering.
In order to make those skilled in the art understand better the technical solution of the utility model, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1 to Fig. 4, wherein, Fig. 1 is that the utility model eyeglass adds the surface structure signal of holding device; Fig. 2 is that the utility model eyeglass adds the structural representation of holding device; Fig. 3 is that the utility model eyeglass adds the structural representation when holding device centering; Fig. 4 is that the utility model eyeglass adds and holds device and add structural representation when holding.
The utility model provides a kind of eyeglass to add and has held device, be used for to eyeglass fixed, add and hold, the processing processing operation after being convenient to eyeglass and carrying out, in the present embodiment, eyeglass adds to be held device and comprise: apparatus main body is provided with rotating spindle on apparatus main body; Be arranged at rotationally the peephole assembly on rotating spindle, comprise observation window 1; Being arranged at rotationally adding on rotating spindle holds assembly, adds to hold assembly and comprise eyeglass sucker 2; LCDs 3, on LCDs 3 be provided with centering and calibrate with cross; The central axis of the central axis of observation window 1, eyeglass sucker 2 is coaxial with the mid point of cross calibration.
In said structure, observation window 1 adopts core structure, its central axis just refers to the axis of core structure, and the center line of eyeglass sucker 2 refers to pass on eyeglass sucker 2 axis of its centre of form, and the mid point of cross calibration, the central axis of examining window are coaxial with the central axis of eyeglass sucker 2.Can guarantee that mechanism adds and holds in the optical centre position by 2 pairs of eyeglasses of eyeglass sucker exactly.Show the crosses calibration because the utility model adopts LCDs 3, can avoid available technology adopting projection centering and the error that produces.
Its reason is, prior art adopt projection legal in, light adopts with the non-perpendicular direction of lens surface and injects eyeglass, the refraction principle of light is arranged as can be known, light is bound to certain skew occurs, thereby causes the location to have deviation.And the utility model is owing to adopting LCDs 3 to show the cross calibration, light penetrates eyeglass with vertical mode from screen, do not reflect, thereby can avoid the alignment deviation that causes due to light refraction, improved the utility model eyeglass is being added accuracy of alignment in the process of holding centering.
Particularly, add and hold assembly and comprise bracing frame, eyeglass sucker 2 is arranged on rotating spindle rotationally by bracing frame.Also comprise drive system, drive system comprises direct current generator 4 and synchronous pulley component 5, and drive motors is controlled bracing frame by synchronous pulley component 5 and rotated.Also be provided with on apparatus main body and trigger the switch that direct current generator 4 begins to reverse.When sucker 2 contacted and adsorbs eyeglass, trigger switch under the effect of mechanical device began counter-rotating, sucker 2 direction revolutions.Can effectively avoid like this causing because the eyeglass thickness is different the eyeglass of crushing.
The utility model also provides a kind of edge polisher, comprises for the edging component that eyeglass is carried out edging operation, comprises also that eyeglass as above adds to hold device.To hold device be all to hold operation as anchor point adds take the optical centre of eyeglass because eyeglass adds, and because positioning datum is identical, therefore, the edge polisher that the utility model provides can process the less glasses of optical centre skew amount.
The eyeglass that the utility model provides adds holds device, its specific operation process such as following.
The first step is carried out mark to the optical centre of eyeglass and axle position, and the eyeglass that is labeled out optical centre and optic axis position is placed on LCDs 3, shows the cross calibration that machine chips calculates on display screen.As for directly over the peephole assembly, on the observation window 1 on operator's eyes, peephole assembly and LCDs 3, cross is scaled to sight alignment state (observation line) to the operator at this moment with eyes.The operator moves to certain position with eyeglass, makes optical centre and optic axis position on eyeglass overlap with cross on LCDs 3 by observation, so completes the location to lens optical center and axle position.
Second step, on eyeglass sucker 2, double faced adhesive tape on sticking note, start direct current generator 4, and direct current generator 4 dresses drive synchronous pulley component 5 runnings.Synchronous pulley component 5 comprises T-shaped Timing Belt, Timing Belt driven pulley, driving wheel, and direct current generator 4 drives driving wheel, and drives the rotation of Timing Belt driven pulley by T-shaped Timing Belt.(the Timing Belt driven pulley is integral by follower shaft and auxiliary turning arm.Auxiliary turning arm and spline housing fixed block are through on rotary main shaft.Spline housing fixed block, splined shaft and spline housing are through together, and wherein spline housing fixed block and spline housing are fixed by screw.)
Driven pulley rotates and drives the bracing frame rotation, and bracing frame drives eyeglass sucker 2 and touches the eyeglass that is placed on LCDs 3, and adheres to.
The advantage that the utility model has is:
1. computer chip calculates the optical centre skew amount of eyeglass automatically, and LCDs 3 shows, when making the center, is to observe straight down all the time, has eliminated the error that causes looking side ways generation due to the skew at center.
2. automatically adhere to sucker, automatic deviation center and the eyeglass of drawing after being offset grind figure, make the human factor reduce, thus the accuracy that assurance centers.
3. adopt the liquid crystal display central cross, eliminated the error that optical projection produces.
4. the optical centre of two mating plates and progressive multi-focus lens and shape are also that the direct computing of computer chip is arranged, and locate more convenient, more accurate.
