The details of the operation of the laser cutting machine motor module and the laser lens laser cutting power control module have been described in the above-mentioned Chinese Patent Application No. 99101280, the details of which are referred to by reference. Incorporating this 1379725 (_D月丨1日修(氧)正换页---I (2012 January 1st revision: Case) In this application, a fixture with a round hole is used to fix the processed circle The spectacle lens, therefore, there is no way to control the operation of the lens to reverse the lens when the lens is chamfered. The clip-on-glass lens holder of the present invention, as the name suggests, uses the uncut lens to accurately fix the lens on the jig. Therefore, the lens can be moved and turned according to the control signal to control the movement of the clamp. Before using the clamp type, the center of the working plane of the lens laser cutting machine must be corrected and found. The working plane center of the laser lens laser cutting machine The figure is shown in Figure 2, in which the laser head is first returned to the hardware zero point 〇h position, and then the laser cutting length is 190 mm and the width is 260 mm. Forming the bottom substrate 31, and cutting the substrate fixing circular hole 32 at the four corners of the bottom substrate with a radius of 1.5 mm, and fixing the bottom substrate 3 i to the working plane 30 using a 3 mm diameter screw. Then using a laser on the quadrilateral substrate The horizontal center line and the vertical center line are drawn on, and the intersection point of the two t-heart lines is the working plane center point 〇 s. After finding the center point of the working plane, the laser is used to sweep out the quadrilateral groove centering on the center point of the working plane. 33, having a length of 15 mm, a width of 220 mm, and a depth of 3 mm, is used for placing a clamped clamp for the clamped base. A clamped clamp according to a preferred embodiment of the present invention As shown in FIG. 3, a fixture base u having a length & 15 〇 _ width of 220 mm can be closely placed into the four-shaped recess 33 in the center of the working plane of FIG. 2. In the middle of the base U is a groove 12 having a length of 95 mm, a width of 100 mm and a depth of 15 mm to avoid collision when the lens is turned over. The surface of the clamp base U' has a virtual horizontal axis and a vertical axis of 1379725. - Y axis And the X axis intersects the Y axis at the origin, this The origin is the center point os of the working plane in Fig. 2. A pair of horizontal fixing seats 14Α, 14Β and a pair of vertical fixing seats 13Α, 13Β are respectively mounted on the horizontal χ axis and the vertical Y axis of the fixture base u A first vertical screw 15 is received by the vertical fixing seat 13A • a perforation corresponding to the diameter of the first vertical screw 15 to be advanced or retracted relative to the clamp base 11; The vertical screw 16 is received by a vertical hole of the vertical fixing seat 13B corresponding to the diameter of the second vertical screw, and is slidable forward or backward relative to the clamp base 11. One has a V-shaped notch The movable collet 2 has a rear end rotatably mounted to a front end of the first vertical screw 15; a fixed collet 22 having a rear end fixedly mounted to a front end of the second vertical screw 16 The front end of the movable collet and the front end of the fixed collet are spaced apart from each other to be suitable for holding an eye lens. Since the size of the spectacle lens is not the same, a compression spring 19 is mounted on the second vertical screw 16 as a biasing member to eliminate the gap between the movable collet 21 and the fixed collet 22. Because the uncut spectacle lens is round, the three points are most stable according to the mechanical point of view. Because the three points on the same plane can draw a circle, as shown in Figure 4. Fig. 5 shows a side view of the portion of the second vertical screw 16 which is mounted to the vertical fixing seat 3B. As shown in FIG. 4 and FIG. 5, the movable collet 21 includes a stepped pillow at the front end thereof and a V-shaped notch on the standing wall of the stepped pillow; and the fixed collet 22 includes at the front end thereof. A stepped pillow' then an uncut spectacle lens 100 can be placed on the level of the stepped pillow of the movable collet 11 1379725 21 and the stepped pillow of the fixed collet 22 and is upright of the stepped stair of the fixed collet The wall and the erected upright wall of the movable stepped pillow are clamped in a three-point contact manner. The compression spring 19 is sleeved on the first vertical screw 16 and is constrained between the vertical fixing seat 13B and the fixed collet 22, because a nut 34 is screwed to the second vertical screw 16, The length of the compression spring 19 can be adjusted. Returning to Fig. 3', the horizontal reference rods 17, 18 having a diameter of 5 mm are respectively provided on the left and right sides of the clamp base π, and are slidably received by the horizontal fixing seats 14A, 14B, respectively. The horizontal reference rods 18 18 are mounted at the same height as the first vertical screw 15 and the second vertical screw 16 (both % mm), and are used as a reference for whether the lens is placed horizontally, and the auxiliary lens The 'optical lens is stably horizontally fixed between the stepped pillow of the movable collet 2丨 and the stepped pillow of the fixed collet 22 for processing. a front end of the first horizontal reference rod 17 is provided with a non-rotatable first detachable collet 23, and a front end of the second horizontal reference rod 18 is provided with a rotatably second detachable collet 24, wherein the first Both the first and second removable collets have a stepped pillow' so that a spectacle lens can be placed on the level of the stepped pillows of the two removable collets and clamped to the upstanding walls of the stair pillows. An inverting motor module group 5 is adapted to receive a control signal to drive 4 the first horizontal reference rod 17 to rotate, so that the first detachable chuck 23, 4 is first detachable and 24 is clamped The lens held between them will be rotated at the same time. The vertical movement of the lens is changed by the positioning motor module 4 according to the automatic control signal rotating the first vertical screw 15 to change the compression of the compression spring ι9 12 1379725 is fixed when the compression spring 19 is half of the compressed length The movable collet 21 is retracted, and the other half is divided into the advancement of the fixed collet 22. It is easy to say that the uncompressed circular spectacle lens is repositioned and the compression amount of the compression spring 19 is equal to the movable collet 21 The retracted distance, that is, the compression amount of the compression spring 19 in Fig. 6 is calculated, that is, the distance at which the movable collet 2 1 retreats is obtained. Therefore, the number of turns in which the first vertical screw is rotated can be obtained by subtracting L2 in Fig. 5 from L2 in Fig. 6 (the amount of compression of the compression spring 19) and dividing the distance of the first vertical screw by one turn. For example, in the case where the lens is not mounted in Fig. 5, the length L2 of the fixing seat 13B to the fixed chuck 22 is 48.63 mm, and the length of the fixing seat 13B to the center line 32 is 76.5 mm. In Fig. 6, the spectacle lens size is 71.47 mm, that is, the lens radius R is 35.74 mm' L1 76.5 mm minus the lens radius 35 74 mm, and the fixing seat 13B to the fixed head 22 is obtained in this case. The length L2 is 40.76 mm ^The compression of the compression spring 19 is equal to L2 (48.63 mm) in Fig. 5 minus L2 (40.76 mm) in Fig. 6 is equal to 7 87 mm, that is, the distance of the movable collet 21 retreat is 7 87 mm. . The displacement of the first vertical screw rotating ring is 2. 〇 3 mm, so 7.87 mm needs to be transferred to about 3 88 laps. Each step of the motor requires 4 pulses, so the number of pulses of 155〇7 is transmitted to the positioning motor module 4〇, and the first vertical screw 丨5 is moved 7.87 mm. The movable chuck 21 can be rotated. The front end of the first vertical screw 15 is mounted. Therefore, when the first vertical screw 15 is rotated back, the movable collet 21 does not rotate, that is, the held lens only retreats and does not rotate. The fixed collet 22 is fixedly mounted on the front end of the second vertical screw 14 137.9725 - 16, so if the second vertical screw is rotated 90 degrees or by a manual turning or rotating button fixed to the second vertical screw At 180 degrees, the fixed head 22, the movable collet 2 1 and the lens held therebetween are simultaneously rotated by 90 or 180 degrees.

Because of the different types of frames, the positioning and flipping planning of the lens-clamping fixtures of each lens will be different. The system flow chart for the two types of frame planning is shown in Figure 7. The system program flow shown in FIG. 7 is to select the size and type of the spectacle lens, calculate the amount of movement of the first vertical screw and the pulse amount to perform the center positioning of the spectacle lens, according to the selected rimless glasses, full-frame glasses or half. The frame glasses frame type performs the process of lens cutting and lens flipping until the lens lens is cut to achieve a cutting lens that conforms to the eyeglass frame. Since the rimless lens is not covered by the frame, there is no problem with the corner of the lens, but the lens must have a circular hole for fixing the lens. The processing steps of this month can be combined with the laser drilling and cutting steps to integrate the various processing steps into the same machining program. First, manually move the horizontal reference rod to the inside of the fixture base so that the uncut lens is placed horizontally, and the straight screwed v-pillow movable chuck has the same height, which represents the lens placement level. The rod exits to the outside of the clamp base.

The horizontal reference rod can be withdrawn to the outside of the clamp base. According to the compression amount of the I-retracting spring of the lens, the motor positioning module drives the number of turns and the pulse amount of the first vertical screw to move the uncut spectacle lens to the center of the laser plane to complete the positioning. Next, the laser lens cutting motion control module is used to perform an orderly point-to-point linear winding motion for laser chamfering. When the front chamfer is completed, the lens is turned to the back side by turning the motor or manually to allow the second vertical screw to rotate. In one embodiment, the number of pulses of 2000 and the forward rotation signal are transmitted to the flip motor for a half turn to drive the second vertical screw to rotate 18 degrees to rotate the lens from the front to the back of the lens. The back side is also finished with a left-right symmetrical movement to the front.
