This altimeter 131 can be an optical height finder, be used for measuring place charging tray 11 optical element to be measured 112 with respect to the central point of the upper surface of charging tray 11 and the distance between this altimeter 131.In the present embodiment, be set at reference value according to the measured distance value of a normalized optical element.The higher limit of described standard value range adds a certain numerical value for this reference value, and its lower limit deducts a certain numerical value for this reference value, and this numerical value comes to determine as required.
This controller 132 can be a diaxon servo motor, comprise first connecting rod 133 and the second connecting rod 134 that links to each other with this first connecting rod 133, under the servo motor effect of (figure does not show), this first connecting rod 133 can rotate around second connecting rod 134, and altimeter 131 can move on this first connecting rod 133.This first connecting rod 133 is set as required with respect to the height of charging tray 11.
Described control device 15 can be a micro treatmenting device, and this control device 15 can be discerned the processing relevant data, and the output result.In the present embodiment, described control device 15 is a central processing unit, and the program that can discern and handle related data is installed in it.
This control device 15 links to each other with the altimeter 131 and the controller 132 of shearer 12, measurement mechanism 13, and can control altimeter 131, controller 132 and 14 operations of control platform of described shearer 12 operations and may command measurement mechanism 13 according to the output result of altimeter 131, concrete control mode is as follows:
Described control platform 14 can be piezoelectric type control platform, is used to carry charging tray 11 and controls it move horizontally.When control device 15 to control platform 14 when sending mobile instruction (as voltage signal), control platform 14 will carry charging tray 11 and move according to instruction.This instruction is sent by built-in relevant preassembled program.
When measuring, the altimeter 131 of this this measurement mechanism 13 of control device 15 may command, controller 132 and control platform 14 carry out coordinating operation, promptly under the control of control device 15, by mobile altimeter 131, simultaneously the first connecting rod 133 of Rotation Controllers 132 and move control platform 14 with the centrally aligned of putting the element under test 112 on the material level 111 of the charging tray 11 that is provided with on the altimeter 131 of described control device 13 and the control platform 14 so that measure the center thickness of this optical element 112 to be measured.The charging tray 11 that on altimeter 131 and control platform 14, is provided with put the centrally aligned of the element under test 112 on the material level 111 time, these altimeter 131 measured height values are minimum, at this moment, this altimeter 131 is passed to control device 15 with this height value, and this control device 15 is just controlled altimeter 131, controller 132 and control platform 14 and stopped to move.
Be understandable that, can only regulate the position of altimeter 131, so that make the centrally aligned of putting the element under test 112 on the material level 111 of this altimeter 131 and charging tray 11 by controller 132.
When the measurement result of altimeter 131 is passed to control device 15, through these control device 15 checks, when exceeding the standard value range of setting as if this measurement result, then described control device 15 return path signals are given shearer 12, stop this shearer 12 operations, with the shearing displacement of the described shearer 12 of instant adjustment.
Fig. 2 is to be example with this embodiment, and the concrete implementing procedure figure of these cutting system 100 method for cutting optical elements please consults Fig. 1 simultaneously, and this cutting method may further comprise the steps:
Step 1: above-mentioned cutting system 100 is provided, comprise a charging tray 11, a shearer 12, a measurement mechanism 13, one be used to place described charging tray 11 and control control platform 14 and control device 15 that this charging tray 11 moves;
Step 2: provide one to treat shearing optical elements 112;
Step 3: this treats that shearing optical elements 112 shears by 12 pairs of control device 15 control shearers, and the optical element to be measured 112 after will shearing places the charging tray 11 of this cutting system 100;
Step 4: the altimeter 131 and the controller 132 of described control device 15 described control platforms 14 of control and measurement mechanism 13, make altimeter 131 centrally aligneds of the optical element to be measured 112 sheared and measurement mechanism 13, and obtain the center thickness value of this optical element 112;
Step 5: described control device 15 is according to this center thickness value, and simultaneously with reference to predetermined standard value range, whether the center thickness of judging this optical element 112 conformance with standard value scope;
Step 6: under the situation of this center thickness value conformance with standard value scope, finish this time and shear.
So, just finish the shearing to optical element 112, if will shear repeatedly, repeating step two gets final product to step 6.
The center thickness value of the optical element 112 that the altimeter 131 of described measurement mechanism 13 is measured, to return to control device 15, through these control device 15 checks, if this center thickness value conformance with standard value scope, then these control device 15 control shearers 12 are sheared next optical element, otherwise stop shearer 12 operations, immediately this shearer 12 is adjusted.
Described cutting system 100 is in the shear history for the treatment of shearing optical elements 112, because the instant supervision of the center thickness of 131 pairs of optical elements 112 of altimeter of measurement mechanism 13, can avoid effectively cutting or to cut the product that causes less bad because of crossing.
In addition, those skilled in the art also can do other variation in spirit of the present invention, as long as it does not depart from technique effect of the present invention, all should be included within the present invention's scope required for protection.
