Abstract
The utility model discloses a centering mechanism for a lens centering holding device. The centering mechanism comprises an observation assembly which comprises an observation window. The centering mechanism is characterized in that a liquid crystal display screen is arranged below the observation window, a cross-shaped calibration for centering is arranged on the liquid crystal display, and during a centering process, the center of the observation window, the optical center of a lens and the intersection point of the cross-shaped calibration are on the same line. The centering mechanism provided by the utility model has the following advantages: the liquid crystal display screen is adopted for displaying the cross-shaped calibration so that light penetrates through the lens from the screen in a vertical mode, thus centering deviation caused by light reflection can be avoided, and the centering precision of the lens in the centering and holding process can be improved.
Description
Technical field
The utility model relates to a kind of eyeglass and adds in fixed and hold device, especially relates to eyeglass that a kind of automatic lens trim grinder uses and adds the centering agency of holding device in fixed.
Background technology
Adding the device of holding in realizing in the market eyeglass is determined is a kind of product that is center instrument, during this product employing projection is legal, be that light adopts the direction non-perpendicular with lens surface to inject eyeglass, refraction principle from light, certain skew can occur in light, need in the time of in fixed manually be adjusted it, and the artificial error of adjusting is larger, can has a strong impact on the accuracy of eyeglass in fixed.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of eyeglass of accurate positioning and adds in fixed and hold device.
The utility model solves the problems of the technologies described above adopted technical scheme:
Add the centering agency of holding device during a kind of eyeglass is fixed, comprise the observation assembly, described observation assembly comprises view window, the below of described view window is provided with LCDs, be provided with the cross calibration that centering is used on described LCDs, in the time of in fixed, the intersection point of the center of described view window, the optical centre of eyeglass and the calibration of described cross is on same straight line.
Described LCDs is connected with the center calculation control system, and described center calculation control system is calibrated and controlled described cross for the cross that calculates eyeglass and is targeted at the position on LCDs.
The xsect of described view window is circular, be provided with polaroid in described view window, the center of described polaroid is provided with a circular hole, and in the time of in determining, the intersection point of the center of described circular hole, the optical centre of eyeglass and the calibration of described cross is on same straight line.Whether the stress that uses polaroid can simultaneously detect eyeglass meets the requirements.
During use at first optical centre and the axle position to eyeglass carry out mark, the eyeglass that is labeled out optical centre and optic axis position is placed on LCDs, show the cross calibration calculated by the center calculation control system on LCDs, the operator by eyes be placed in view window directly over, operator's eyes now, on view window and LCDs, cross is scaled to the sight alignment state, the operator moves to certain position by eyeglass, by observation, make optical centre and optic axis position on eyeglass overlap with the intersection point of cross calibration on LCDs, so complete the location to lens optical center and axle position.
Compared with prior art, the utility model has the advantage of: adopt LCDs to show the cross calibration, light penetrates eyeglass with vertical mode from screen, can avoid the alignment deviation caused due to light refraction, thereby improved, eyeglass is added to the accuracy of alignment in the process of holding centering.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model:
As shown in Figure 1, add the centering agency of holding device during a kind of eyeglass is fixed, comprise and observe assembly 1, this observation assembly 1 comprises view window 2, the below of view window 2 is provided with LCDs 3, is provided with the cross calibration that centering is used on LCDs 3, in the time of in determining, the intersection point of the optical centre of the center of view window 2, eyeglass 4 and cross calibration on same straight line, i.e. sight alignment.
In this specific embodiment, LCDs 3 is connected with the center calculation control system, and the center calculation control system is calibrated and controlled cross for the cross that calculates eyeglass 4 and is targeted at the position on LCDs 3.
In this specific embodiment, the xsect of view window 2 is circular, is provided with polaroid 5 in view window 2, the center of polaroid 5 is provided with a circular hole 6, in the time of in fixed, the intersection point that the optical centre of the center of circular hole 6, eyeglass 4 and cross are calibrated on same straight line, i.e. sight alignment.Whether the stress that uses polaroid 5 can simultaneously detect eyeglass 4 meets the requirements.
During use at first optical centre and the axle position to eyeglass 4 carry out mark, the eyeglass 4 that is labeled out optical centre and optic axis position is placed on LCDs 3, show the cross calibration calculated by the center calculation control system on LCDs 3, the operator by eyes be placed in view window 2 directly over, operator's eyes now, on view window 2 and LCDs 3, cross is scaled to the sight alignment state, the operator moves to certain position by eyeglass 4, by observation, make optical centre and optic axis position on eyeglass 4 overlap with the intersection point of cross calibration on LCDs 3, so complete the location to eyeglass 4 optical centres and axle position.
