This web member 66 here is made of the thicker flat shim made from polyfoam or rubber, and the thickness of this pad makes the axle of operating rod 60 can tilt a little with respect to the 3rd sliding axle A3 when the intensity of transverse stress F1 strengthens.
Itself comprises the stress gauge here described harvester, and this gauge is suitable for measuring the elastic deformation of web member 66 and sends the signal of representing this distortion to the capture card of the central location 20 of desktop computer.This stress gauge can be incorporated in the web member 66 by being fixed on the bonnet 62 or being fixed on the framework 61 alternatively.
Signal that the software for calculation of central location 20 thereby can handle is sent by the stress gauge and the intensity that indicates transverse stress F1 when measured stress are presented at error signal on the display screen 11 during above predetermined threshold, described threshold value preferably equals 0.5 newton between 01. to 1 newton.
As modification, can use other harvesters that are used to gather web member 66 distortion, these harvesters also can detect intensity equal described threshold value transverse stress F1 feature stresses or move.For example, the Y-piece with light-analog sensor can be installed in the chamber 66 of framework 61 with gage frame 61 relatively moving with respect to main carriage 90.
For example shown in Figure 1, the 3rd sliding axle A3 of identification apparatus 1 flatly extends, so that 80 axial locations with respect to main carriage 90 of popping one's head in can not be subjected to any action of gravity.
It is unhelpful that the weight of popping one's head in when therefore, the device that is provided for compensating the quality of probe 80 is avoided shape when identification lens model 200 or spectacle-frame 100 influences its track.
In addition, as shown in Figure 3, when the user inlayed the scanning disk 82 of probe 80 facing to the bottom of the groove 103 of periphery 101, it was owing to the weight in groove 103 bottoms is maintained.
As modification, it is contemplated that and place or arrange base in a different manner, so that the 3rd sliding axle for example vertically extends.In this modification, described identification apparatus comprises the device of the quality that is used to compensate probe 80, so that can not be subjected to any influence of gravity for the identification of the shape of lens model 200 or spectacle-frame 100.These devices can be for example by spring, counterweight or or even the engine-scrambler of main carriage form.
Discrimination method
According to element to be identified is the periphery 101 of spectacle-frame 100 or lens model 200, shrewd knowledge method with two parts.
For one of periphery 101 of scanning ophthalmoscope frame 100, described method comprises three key steps.It that is to say from the bottom of groove 103 particularly including spectacle-frame 100 being blocked in first step in the support member 30,40, placing second step of probe 80 and the third step that scans peripheral 101 profiles against the groove 103 of the periphery 101 of living spectacle-frame 100.
During first step, the selected spectacle-frame 100 of following wearer is installed in (Fig. 1) in the identification apparatus 1.For this reason, thereby the user catches operating rod 41 and it is pulled to high-order periphery 101 with spectacle-frame 100 insert in the groove of fluting protruding pins 36, then he unclamp operating rod 41 so that the cheek of this operating rod 42 against the bridge of living spectacle-frame 100.Spectacle-frame 100 thereby fully remain in the base 30.
During second step, the user catches the bar 81 of the probe 80 of initial plate 34 facing to base 30, and his will pop one's head in 80 scanning disk 82 is positioned to bottom facing to the groove 103 of periphery 101 then, as the special demonstration of Fig. 3.Under action of gravity, scanning disk 82 remains on its position when user's unstick 81.User thereby selection and neighboring scan corresponding calculated pattern on its desktop computer.
During third step, the user catches operating rod 60, and he moves to this operating rod among the principal plane P1 then, so that 80 the scanning disk 82 of popping one's head in is along the basal sliding of the groove 103 of periphery 101 and contact whole circular contour.
Since probe 80 with respect to operating rod 60 and V-shaped groove 103 along the 3rd sliding axle A3 translation freely, therefore when the user to popping one's head in 80 when applying suitable transverse stress F1, scanning disk can not climbed up along the side in the both sides of this groove 103 along the basal sliding of groove 103.
During this third step, software for calculation has been measured the volume coordinate of a plurality of unique points of 80 the track of popping one's head in.
For this reason, described software just begins to measure in per 1/10th seconds the volume coordinate of a some that time at the selected corresponding neighboring scan computation schema of its desktop computer from the user.
Then, when described software detection when the volume coordinate of one of institute's identification new point is substantially equal to the volume coordinate of first point of being discerned, this means that probe 80 gone over whole profiles of periphery 101, described software stops to measure volume coordinate.Its calculates the total duration of the profile of identification periphery 101 then, if this duration is less than or equal to 5 seconds, it just sends error signal to order the user again with the shape of slower Speed identification periphery on screen 11.
If this duration surpasses 5 seconds, this software just calculates the volume coordinate of the center of gravity of the point of being measured, and it determines the derivative of each measuring point then.If this derivative is different between the continuity point of two mensuration, surpass 0.1mm/rad (for the point of the angle that separates 360/800 degree usually around center of gravity), this means then and find that breakpoint and this identification correctly do not carry out that this software for calculation sends error signal to order user's identification peripheral shape carefully again on screen 11.
As modification, it is contemplated that as the user and send the coordinate that described software when ceasing and desisting order stops to measure the point of peripheral profile by user interface 10.According to this modification, after the user sent this order, described software detected the step of the point of peripheral profile automatically, confirmed to pop one's head in during this step to have realized exactly all rotating for scanning whole peripheral 101 profile.
If described probe has only carried out the part that all rotates, this means then and do not measure profile fully that described software sends error signal and carries out identification again with the order user on screen 11.
If probe has carried out more rotating than all rotating, this means that then some point are determined twice, described software deletion " overlapping " that is to say those redundant points.
Then, owing to store the diameter of probe 80 scanning disk 82 in the central location, the coordinate that therefore described software for calculation is handled institute's measuring point is with the shape of the bottom of inferring groove 103 and store the Exact Number image of this shape.
Be at (with respect to how much initial points on the free end that is positioned at beam 32) between 0 to 80 millimeter or between 80 to 160 millimeters according to coordinate then along the axle A1 of center of gravity, to this image distribute digital label " right side " or " left side ", this means that the profile of being measured is corresponding to the right of spectacle-frame 100 or left side periphery 101.
After this step finished, probe 80 was by taking-up from groove 103 and against the plate 34 of living base 30.The user can carry out the precise number image of these operations with the bottom of the groove 103 of second periphery 101 that obtains spectacle-frame then repeatedly.
At last, described software for calculation order on display screen 11, show two peripheries shape digital picture and store these shapes.
During this third step, if described identification apparatus is equipped with the harvester of transverse stress F1, the stress that then described software for calculation continuous acquisition is measured by the stress gauge is inferred the intensity of transverse stress F1 continuously and this transverse stress F1 is compared with predetermined threshold continuously.Then, if this transverse stress F1 surpasses this threshold value (0.5 newton), then described software command display alarm signal on the display screen 11 of desktop computer rescans periphery 101 with the suggestion user by operating rod 60 being applied less power.
Described software for calculation can also be used for order and show measured stress value continuously on display screen 11, thereby helps the user that periphery 101 is applied suitable transverse stress F1.
In order to scan the lens model 200 that is equipped with the perforation picture frame that the wearer selectes, described method comprises three key steps.It is particularly including the third step of the perforation 201 of second step of the profile that lens model 200 is blocked in first step in the support member 30,40, scanning lens model 200 and scanning lens model.
During first step, lens model 200 is removed from its spectacle-frame.Then its central opening is embedded on the center protruding pin of the base that for this reason provides.Lens model 200 thereby for example be blocked on this protruding pin by rigidity by means of being tightened on the nut on this protruding pin.This base embed then in the identification apparatus 1, the position between the cheek 42 of the groove of the fluting protruding pin 36 of plate 34 and operating rod 41.Lens model 200 thereby remain on well in the base 30.The user selects and scanning lens model corresponding calculated pattern on its desktop computer then.
During second step, the user catches operating rod 60, then he this operating rod is moved among the principal plane P1 so that bar 81 along the whole profile of lens model 200 and slide.
During this step, described software for calculation is measured a plurality of characteristic point coordinates of the track of probe 80 in principal plane P1.Coordinate along these points of the 3rd sliding axle A3 does not have processed.Then, because central location 20 has been stored the diameter of bar 81, so this software for calculation is handled profile the projection of shape among principal plane P1s of these coordinates to infer lens model 200.Precise number image and order that it also can store this shape show this digital picture on display screen 11.
As scanning ophthalmoscope frame periphery, it is contemplated that described software is automatically ordered and stop this profile of identification or this stops by user interface 10 manual command by the user.
During third step, the user handles operating rod 60 and contacts with the front surface of lens model 200 with 80 the scanning tip 83 of will popping one's head in.Then, he moves this operating rod so that scanning tip 83 enters each perforation 201 of lens model 200, and then comes out and contact around the front surface of each perforation lens model 200 of 201.
Should be appreciated that then this operation becomes easy if identification apparatus 1 comprises to be used for probe 80 is retracted device with lens model 200 position contacting.
During this step, when probe was arranged in each perforation and is positioned on the edge of each perforation, described software for calculation was measured the volume coordinate of this probe especially.The mensuration of these coordinates can be come the artificially order by user interface 10 by the user, perhaps can automatically be ordered when detecting probe along the 3rd sliding axle unexpected mobile by described software for calculation.These volume coordinates are processed in such a way then.
Because central location has been stored the angle value TETA at top of scanning tip 83 and described software for calculation and obtained to pop one's head in when embedding perforation at 201 o'clock and be positioned on the edge of perforation 201 along position Z1 and the Z2 of the 3rd sliding axle A3, so calculation element is determined this minimum diameter D1 of 201 of boring a hole by following mathematical formulae:
D1＝2.tan(TETA/2).(Z2-Z1)。
At last, described software for calculation order shows the image with the perforation 201 of the image relay of the profile of lens model 200 on display screen 11.
Behind these different EOs, the central location of desktop computer can transmit all geometric properties of being gathered to the profile machining cell, thereby makes this profile machining cell can process wearer's eyelens.
