Detailed Description
As shown in fig. 1, the general glass cutting machine is modified into a precision mapping system, and the specific method comprises the following steps: firstly, a marble or cast iron flat plate with the precision of 0 or 1 grade is installed on the table top of a cutting machine and is used as a measuring table top, glass to be measured is buckled on the measuring table top in an inverted mode (the convex surface is upward), a laser displacement sensor with the measuring direction vertically downward is fixed on a glass cutting head, the laser displacement sensor is driven to move to any position on the upper surface of the glass to be measured by the aid of forward and backward movement (Y direction) of a beam of the cutting machine on the table top and left and right movement (X direction) of the cutting head on the beam to measure the displacement distance, and the measuring result is input into PLC measuring and controlling equipment. The PLC measurement and control equipment is connected with the original glass cutting machine controller, a pre-designed X-Y motion track is input into the original cutting machine controller through the PLC measurement and control equipment, and the original cutting machine controller controls the laser displacement sensor to move to any position on the surface of the glass. The measuring direction of the laser displacement sensor is vertical downward, the distance from the highest point of the surface of the glass to be measured is less than 200mm, the measuring error of the sensor is less than 0.1mm, and the repeated measuring precision is less than 0.1%. The laser displacement sensor needs to be a high-precision laser sensor special for measuring transparent glass. A rectangular box slightly larger than the projection size of the glass is planned in advance on the measuring platform and used as a measuring area. The stepping distance of the laser displacement sensor moving along the Y direction of the rectangular frame is 1-10 mm, and the moving speed along the X direction is 0.1-2 m per second. The sampling frequency of the PLC measurement and control equipment to the laser displacement sensor is 10-100 times per second. The scanning measurement method comprises the following steps: starting from the bottom side of the rectangular box, the beam advances one step at a step distance in the Y direction, and the cutting head carries the right side of the laser displacement sensor moving at a predetermined speed from the left side of the rectangular box. And the PLC measurement and control equipment records the output value of the laser displacement sensor at a preset sampling frequency until all scanning and sampling in the rectangular square frame are completed.
Practical implementation and production cases:
a common automatic glass cutting machine with the length of 4m (Y direction) and the width of 2.4m (X direction) is adopted, and a marble measuring table with the precision of 0 grade and the size of 3m multiplied by 2m multiplied by 0.04m is arranged on the table surface of the cutting machine.

A laser displacement sensor which is specially used for measuring the glass distance and has the error precision of 0.1mm is fixed on a glass cutting head of a beam of the cutting machine, and a sensor probe is 200mm away from a marble table top and is used for measuring curved glass with the maximum arch height of 150 mm. The glass cutting machine controller is connected with the PLC measurement and control equipment, so that the PLC measurement and control equipment can receive dynamic position information from the cutting machine controller, distance measurement data output by the laser displacement sensor and a control instruction of the PLC measurement and control equipment to the cutting machine controller.
A piece of hyperboloid glass with the maximum arch height of 100mm and the size of 2m multiplied by 1m is buckled on a platform, a rectangular box capable of surrounding the projection of the glass is marked on the periphery of the glass, the size of the rectangular box is 2.2m multiplied by 1.1m, and one corner of the rectangular box is set as a coordinate origin. And inputting an X-Y motion trail diagram capable of covering the rectangular box and operation control information on a cutting machine controller. The input control information is: the movement speed of the laser displacement sensor in the X axial direction is 1 m/s; and returning to the position where X is 0 after moving to the end of the rectangular box; the beam is then stepped 5mm in the Y-axis direction and the operation is repeated until the beam has traveled to the Y-axis end of the rectangular box. And in the process of forward movement of the laser displacement sensor, the PLC measurement and control equipment collects output data of the laser displacement sensor according to the sampling frequency of 200/s.
After starting according to above-mentioned setting, PLC measurement and control equipment is every 5mm to the X direction and the Y direction of glass upper surface and gathers a distance data from laser displacement sensor, and the data value of establishing the collection is Zn, and then any one point of curved surface glass surface is to platform surperficial numerical value Zxy and is: and Zxy-200-Zn, the X, Y value is recorded in PLC measurement and control equipment synchronously with Zxy in the process of motion acquisition, and the contour map of the curved glass to be measured can be drawn according to the value of each point X, Y, Z.
