Deng.
The course of work and principle：Before vertometer is not used, 6314 energizing magnetic of the first electromagnet, the magnetic of generation
Property direction repel each other with the first magnet 6313, to make jacking block 638 overcome the elastic force of the first spring 639 to far from drive block 638
Direction is moved, and in this way when vertometer is not used, even if rotating bar 631 rotates, whole device will not act, and make stabilizing mechanism
6 are protected in the case that device is not used, prevent non-operator stable operation mechanism 6, device is caused to damage, and in addition
Two electromagnet 6415 power off, and check lock lever 6411 is made to be connected to the inside of upper notch 643 under the elastic force effect of third spring 6414,
Make drive link 66 keep motion state consistent by check lock lever 6411 with lead screw 67, when using vertometer, first places eyeglass
To the top center position of collimator objective 5, when video camera 4 senses that eyeglass is placed on collimator objective 5, operating personnel according to
Use habit selects the knob assembly 63 of left or right side by fingerprint identification device 65, burnt in operator's once-through operation in this way
It spends timing to move come the other component of control device by the knob assembly 63 of side, the knob assembly 63 of the other side is in
Dormant state will not influence operator behaviour operating knob assembly 63 of the other side by other staff in operation
Make vertometer, this ensure that the continuity of operator in operation, when operator chooses knob assembly 63, first
The power-off of first electromagnet 6314 loses magnetic force, and jacking block 638 is under the elastic force effect of the first spring 639, to close to drive block 636
Direction is moved, when drive block 636 and jacking block 638 are in close contact using the elastic force of the first spring 639, due to drive block 636 with
The surface roughness of jacking block 638 is very high, and then makes the movement shape of the two by the frictional force between drive block 636 and jacking block 638
State is consistent, at this moment turn knob 6315, and then rotating bar 631 is made to rotate, in drive block 636 and 638 motion state of jacking block
In the case of being consistent, shaft 632 rotates, and then makes interlocking bar under the drive of master bevel gear 633 and linkage bevel gear 615
614 rotation, and then drive secondary bevel gear 613 and rotated from bevel gear 612, and then drive link 66 is driven to rotate, due at this time
Under the action of check lock lever 6411, drive link 66 is consistent with 67 motion state of lead screw, and such driving plate 6410 is in middle circular trough 649
Interior rotation, locating piece 647 rotation, lead screw 67 in lower circular trough 645 drive push plate 617 to be rotated down in rectangular channel 68, into
And catch bar 610 is driven to move down, Buffer Unit 69 can move under the linkage effect of catch bar 610 to close to the direction of eyeglass
Dynamic, when Buffer Unit 69 touches lens surface, gradually stabilized eyeglass, buffer bar 693 overcome second spring to steady rest 691
696 elastic force moves up, during 691 stabilized lenses of steady rest, when pressure sensor 697 detects steady rest 691
When pressure value between eyeglass reaches setting value, continuing to move down for anti-thrust plate 617 can make the pressure of eyeglass is excessive to make
It is damaged at eyeglass, the second electromagnet 6415 energization generation magnetic force is simultaneously mutually exclusive with the magnetic force of the second magnet 6416, makes check lock lever
6411 overcome the elastic force of third spring 6411 and are moved in circular trough 644, even if at this moment knob assembly 63 is rotated further, silk
Bar 67 will not act, safety accident caused by causing eyeglass broken so as to avoid human hand dynamics is excessive, after eyeglass is fixed, into
The follow-up measurement process of row, after being measured, the second electromagnet 6415 power-off, check lock lever 6411 is made in the elastic force of third spring 6414
It is snapped fit onto again in upper notch 643 under, knob 6315 inverts, and drives Buffer Unit 69 to move up, when being moved in situ, takes
Lower eyeglass, 6314 energizing magnetic of the first electromagnet, the magnetic direction of generation are repelled each other with the first magnet 6313, make drive block
636 detach with jacking block 638, and the Movement consistency of such rotating bar 631 and shaft 632 destroys, and facilitates next use.
Based on above-mentioned, vertometer using the present invention fixing len holder is filled in fixing len by fingerprint recognition
It sets to judge that operator is operated by left hand or the right hand, after the completion of identification, corresponding knob assembly is connected, and passes through stabilization
Eyeglass is fixed in Buffer Unit in mechanism, does not need human hand in this way and pins fixing len holder downwards, can effectively prevent
Only eyeglass is due to damage caused by rubber sleeve, when the pressure sensor in Buffer Unit reaches pressure set points, controls protection group
Part starts, and the movement connection relation of drive link and lead screw is made to separate, and causes eyeglass is broken to make so as to avoid human hand dynamics is excessive
At safety accident.
As known by the technical knowledge, the present invention can pass through the embodiment party of other essence without departing from its spirit or essential feature
Case is realized.Therefore, embodiment disclosed above, all things considered are all merely illustrative, not the only.Institute
Have within the scope of the present invention or is included in the invention in the change being equal in the scope of the present invention.
