Return to the position of the hardware zero point ,h, and then use the laser to cut the bottom substrate 31 having a length of 190 mm and a width of 26 mm, and cut the radius of the substrate fixing hole 32 at the four corners of the bottom substrate of 10 1373389. i 5mm 'Use the 3mm diameter screw to fix the bottom substrate 3i on the working plane 3〇 and then use the laser to draw the horizontal center line and the vertical center line on the quadrilateral substrate. The focus of the two center lines is the center of the work plane, find out the work. After the plane-center point, the quadrilateral groove 33 centered on the center point of the working plane is cleaned by laser, and its length is 150mm, the width is 220mm, and the depth is 3mm, which is used for placing the circular hole lens holder. After the lens laser cutting machine working plane center, the circular aperture glasses lens fixture needs to be placed in the quadrilateral groove in the center of the working plane, and the circular aperture glasses lens fixture diagram is shown in Fig. 5. The circular aperture lens fixture 4 〇 is a quadrilateral wood board with a length of 150mm, a width of 220mm, a thickness of 5mm, a circular hole 41 in the middle is cut by the center of the quadrilateral center, and the diameter of the round hole is three different specifications of the lens selected according to the invention. The diameters are 71.47 mm, 69.88 mm, and 64.67 mm, respectively. When using a round-hole lens holder to cut the spectacle lens, first determine the specifications of the lens, and use the φ-size round-hole lens holder to put the lens into the hole, and then install the lens with the hole. The clip is placed in the groove - in the bottom substrate on the work plane to cut the spectacle lens. Pupil Center Focusing The lens laser cutting method of the present invention requires alignment of the center position of the original lens with the center of the lens laser cutting platform prior to processing, and then adjusting the horizontal and vertical position of the lens pattern based on the pupil center position of the lens. When the wearer wears the glasses, the position of the pupil must match the optical center position of the lens 11 1373389* to ensure the comfort of the eyeglasses to achieve the function of assisting vision. Therefore, the present invention plans the correlation between the frame and the eye part of the wearer. The parameters, in order to promote the laser cutting of the spectacle lens, can more accurately and completely meet the needs of the optician. The parameter frame of the eyeglass frame is shown in Figure 6, where the geometric center (gc) is the point where the two long sides or the two wide sides of the eyeglass frame are equidistant. Geometric center distance (gcd): The geometric center distance, also known as the frame pitch (FPD), is the distance between the two geometric centers of the left and right frames of the frame. Lens pitch (DBL): The lens pitch, also known as the Bridge Size, is the shortest distance between the left and right frames of the frame, ie the size of the nose bridge. Lens size (L): The horizontal length of the frame, that is, the distance between the outermost point and the innermost point of each frame of the left and right eyes. Lens height (H): The distance between the highest point and the lowest point of each frame of the left and right eyes. Punch center (〇). The position of the center of the hole on the lens when the lens is punched. Punch Diameter (D): The length of the diameter of the perforated circle on the lens when the lens is punched. The eye parameters of the optician are shown in Figure 7, where the pupil center (p): the pupil center distance (FPD): the distance between the left and right pupil centers of the optician. Left eyelid distance (PDL): The left eyelid distance is the distance from the center of the pupil of the left eye to the center of the bridge of the nose. Right eyelid distance (PDR): The distance between the right eye and the eye is the distance from the center of the pupil of the right eye to the center of the nose. Pupil height (pH): The pupil height is the vertical distance from the center of the pupil of the optician to the lowest edge of the inner edge of the frame. When the distance between the opticians and the geometric center of the frame coincides, the center of the lens is not required to be placed, and the optical center of the lens is placed at the geometric center of the frame. If the geometric center of the lens does not match the distance of the optician, the center of the lens is shown in Figure 8, where the geometric center of the frame 1〇〇 changes with the distribution of 12 1373389 'here for the 200 degree spherical myopia lens calculation The thickness of each point of the cut lens edge seat is used to accurately adjust the laser power for the depth of the point when cutting the front and back chamfers, and reduce the depth deviation caused by the spherical surface. In order to make the lens and the frame more closely fit, the present invention adjusts the power of the laser to chamfer the edge of the lens, and the laser cutting method used in the laser cutting system of the spectacle lens is to adjust the ratio of laser excitation on/off time. (T〇n/T〇ff) way to change the laser light power to perform lens cutting. The point-to-point motion trajectory of the lens is planned. The laser lens cutting trajectory planning is based on the private point of the lens laser cutting pattern. The amount of movement of the shaft and the Y-axis is converted into a pulse signal and transmitted to the stepping motor module. The stepping motor used in the present invention has a specification of per revolution. It takes 4,000 pulses to move one turn, and the distance between the x-axis and the γ-axis motor is 50 mm. Therefore, it is known that one pulse is required every 1 mm of the motor rotation. The motion mode of the lens laser cutting is the lens cutting pattern coordinate. The point is linearly moved from point to point. The laser cutting trajectory of the spectacle lens is shown in Fig. 9. In Fig. 9, A1Α2 points are two points of the lens pattern coordinate, and the X coordinate and the Y axis direction of the point coordinate position are subtracted. Calculate the 移动 axis movement centroid and the Y-axis movement amount dy', then convert the moving centroid and the rushing upper rib pulse/mm into a pulse amount, and then send it to the spectacle lens laser cutting motion control group to perform the linear path interpolation wheel. The pulse signal is sent to the stepping motor module to drive the motor to rotate. The flowchart of the laser lens laser cutting program is shown in Fig. 1(). The cutting program flow of the present invention shown in Fig. 10 uses the frame coordinate data from the first

When the spectacle lens is cut, the thickness of each point of the outer edge of the cut lens must be calculated, and the front surface and the ejection surface are cut. _1 When chamfering, it is possible to accurately adjust the magnitude of the force rate for each point depth of the lens edge and reduce the depth deviation caused by the spherical surface. In this case, the laser chamfering is illustrated. The side view of the edge of the full-frame lens is as shown in Fig. _ A Γ Γ is the chamfer radius of the edge of the lens. When the full-frame lens is chamfered, it needs a 'secondary processing, and then the next After the completion of the back laser cutting chamfering, the lens is turned to the left and right of the anti-cutting system: the chamfered laser cutting. The minimum line width of the lens laser cut 63~°j used in the present invention is 〇.lmnl, and the laser focal length range is •. When the full-hinge lens and the continuous laser chamfering, the number of chamfering layers affects the fineness of the surface of the laser 1367389 edge chamfering surface, and the number of the laser-chamfering cutting layer is less when the chamfering radius is not changed. For a long time, the chamfered surface of the lens edge is more than Jr Φ P rr» ** one is easy because the number of layers is too small, the amount of feed is too small, causing the laser energy to be too f 聋 · Φ > +77 ΦΙ Η ' When the number of layers is too small, The rougher the chamfered surface of the lens edge, the easier to complete the chamfering slope. The laser cutting layer number η of the present invention is between 5 $_10 夕1 pq and the inter-frame lens chamfer depth map is as shown in Fig. 13. The number of chamfered cutting layers is n. If the angle of the chamfering is 45 degrees, the increase of the thickness of each layer of laser cutting J is the chamfering radius ^ length divided by η#, and the laser head is fed outward. The angular radius Γ length divided by n] layer due to the minimum line width of laser cutting is 〇.lmm 'so the laser head must be larger than 0.05mm, each feed is the front and back of the lens For the spherical surface, the depth D1 of each point of the edge of the laser cutting lens at the middle of the edge of the lens at the chamfer of the cut is as shown in the formula (9). One half of the thickness of the lens is subtracted from the first—the depth increase of the laser cutting of the a ^ layer, and the depth D2 of the edge of the laser cutting lens of the flute _ layer is as follows: one is half the thickness of the lens minus the first - No, the middle and the upper layer are cut layer by layer, and the amount is increased in this way, and the back chamfer is completed by the cutting method. The use of poor face is also used (9) A = jade - [(Bu ") χ (η-2)] 17 (10) 1373389 The power of the laser lens for laser lens cutting of the lens lens must be matched with the cutting speed. The cutting power has a large speed and the I energy is strong. The cutting power is fast and the speed is fast. Therefore, the processing time is short. The accumulated energy on the workpiece is relatively reduced. The fineness will increase the cutting power. The energy is small but the processing power of the cutting is small and fast. It is suitable for thin workpieces because the energy is small and it is not suitable for the deep cutting method of the laser cutting method (Ton/Toff). Carry out the lens. The eyeglass lens Ray of the present invention is to adjust the opening/cutting of the laser source, and the two-point output of the laser-cutting motion control module through the spectacle lens is controlled by two (four), one peach off signal 'when the output signal is 3.3~5 When the voltage between volts (v) is high, the laser power source turns on the laser tube to excite the laser light. When the output signal is at a low potential of 〇~3 3 volts, the laser is turned off. The other control signal is a signal for controlling the magnitude of the laser power, and adjusts the ratio of the opening (four) and the off (off) of the duty cycle of the sent pulse signal, and the adjustable range is 〇~1〇〇% (%), which is used by the present invention. Inverting amplifier, please reverse the output signal and amplify it to the voltage level that can be accepted by the laser power controller in the glasses laser cutting power control module. When the glasses lens laser cutting motion control module outputs When the signal duty cycle percentage is 20%, the waveform of the laser power signal duty cycle is shown in Figure 。. The upper waveform in Figure 14 is the output signal of the laser lens cutting motion control module of the spectacle lens. The duty cycle is 2〇%, the signal frequency is 2.12kHZ, and the average voltage is 2.6 volts. After the reverse amplification, the waveform below is laser. The signal input at the power controller's duty cycle is 79 6%, the signal frequency is 2.12 kHz, and the average voltage is 4.07 volts. The laser tube 18 1373389 < · 'excited laser power is 47.7 watts. When the operating period of the output signal of the glasses lens laser cutting motion control module is 50%, the waveform of the laser power signal working cycle of 5〇% is shown in Fig. 15. The upper waveform in Figure 15 is the output signal of the laser lens cutting motion control module of the spectacle lens. The duty cycle is 50%, the signal frequency is 2.13kHz, and the average voltage is 2.6 volts. After the reverse amplification, the waveform below is the laser power source. The input signal of the controller has a duty cycle of 5〇%, the signal frequency is 2.13kHz, and the average voltage is 4 〇7 volts. The laser light stimulated by the laser tube is half of the full open, which is used by the present invention. The laser device is 60 watts' so the percentage of duty cycle is 5〇%, which is 3 watts. As described above, the present invention actually cuts two types of spectacle lenses into full-frame glasses and rimless glasses, and uses a CCD lens to take a frame according to the laser lens laser cutting process, and uses image processing technology to detect the edge of the inner edge of the frame. The lens edge coordinate points are merged into the eyeglass lens laser cutting system. The coordinates of the inner edge of the frame are converted into the coordinates of the actual size by the pixel and the correction value, and the lens pattern is calculated as the offset coordinate according to the position of the pupil of the lens. Then, through the laser lens cutting trajectory of the spectacle lens, the motion path of the lens laser cutting-cutting is planned, and then the control signal is outputted by the spectacle lens laser cutting system to the laser lens of the spectacle lens laser cutting machine and the laser cutting power control of the spectacle lens. The module performs lens cutting. The invention independently designs the special shape of the rimless glasses to perform laser cutting, and increases the elasticity of the styling change of the rimless glasses. The actual completion of the special shape frameless lens diagram is shown in Figure 16. The frameless lens cut by the invention needs to use two round holes for fixing the frame, and cuts 7 round holes for modeling on the lens, and the edge of the special shape rimless lens lens is straight 19 1373389 to cut off, in order to avoid Energy is accumulated during edge laser cutting, and multiple cuts are performed using low power.
