[0002] When producing lenses, in order to meet production needs, the raw material plates of the lenses must be precisely cut. In view of the brittle nature of the raw material plates of the lenses, the most commonly used cutting method is laser cutting technology. This technology uses a high-energy laser beam to precisely focus on the surface of the raw material plates of the lenses to produce cracks on the raw material plates of the lenses, thereby cutting the raw material plates of the lenses with preset contours. The cracking head will heat these cracks to achieve precise breaking and separation of the lenses. The advantage of laser cutting is that it can effectively reduce burrs on the edges of the lenses and improve the edge quality of the lenses.

[0003] However, when using laser cutting, since the material of the lens raw material plate has high reflection and scattering characteristics to the laser, this causes the energy of the laser beam to be dispersed, thereby affecting the cutting efficiency of the lens. In order to ensure the cutting quality and efficiency of the lens, it is necessary to increase the energy input of the laser beam, which will undoubtedly increase energy consumption. That is, the existing laser technology has defects that need to be overcome when cutting lenses. Summary of the invention

The screw 901 first controls the applicator 8 to move forward. When it moves to the transition position of the arc-shaped guide surface of the guide frame 10, the return spring 11 can restore the deformation and move the applicator 8 upward. Then, the applicator 8 continues to move forward to make the second interface 801 dock with the first interface 701, so that the anti-reflective coating enters the applicator. 8 and soaks the material at the bottom thereof, then, the screw 901 is reversed to control the applicator 8 to move backward, and at the transition position of the arc-shaped guide surface of the guide frame 10, the applicator 8 is controlled to move downward, so that the material at the bottom of the applicator 8 contacts the lens raw material plate, and the return spring 11 is stretched, so that the applicator 8 can evenly apply the anti-reflective coating on the lens raw material plate during the backward movement. By using the anti-reflective coating on the lens raw material plate, the reflection and scattering of the laser beam on the lens raw material plate are reduced, the utilization rate and cutting efficiency of the laser beam are improved, unnecessary energy consumption is reduced, and the cost is reduced;

[0032] After the anti-reflective coating is applied, the numerical control system is used to preset the moving paths of the laser head 3 and the splitting head 4. The numerical control system first controls the laser head 3 to move along the preset path through the first frame 2, thereby cutting a contour on the lens raw material plate. Then, the numerical control system controls the splitting head 4 to move along the preset path through the first frame 2, heats and splits the cut contour, thereby separating the lens from the lens raw material plate.

[0033] like Figure 6-Figure 8 As shown, a rotating rod 502 is arranged at the front side of the placing tray 5, and the placing tray 5 is rotatably mounted on the processing table 1 through the rotating rod 502; it also includes: a receiving frame 12 fixedly mounted on the processing table 1, the receiving frame 12 is located below the placing tray 5, and the lenses separated on the placing tray 5 will pass through the hollow position of the placing tray 5 and be collected in the receiving frame 12, the bottom of the receiving frame 12 is inclined, and a discharge port 1201 is arranged at the lowest position of the bottom of the receiving frame 12; an inclined guide seat 13 fixedly mounted on the processing table 1, the inclined guide seat 13 is located at the front side of the placing tray 5, and its top end is connected to the placing tray 5; slide grooves 14 are provided on both sides of the processing table 1; a sliding frame 15 slidably mounted on the slide grooves 14 The sliding frame 15 is provided with a control shaft 1501 in the sliding groove 14; the second motor 16 is fixedly mounted on the sliding frame 15; the gear 17 is fixedly mounted on the output end of the second motor 16; the gear row 18 is fixedly mounted on the lower part of the processing table 1, the gear 17 is meshed with the gear row 18, and the gear 17 rotates to cooperate with the gear row 18, so that the gear 17 will produce relative displacement with the gear row 18; the protrusion 19 is fixedly mounted on the rear side of the bottom of the placement plate 5, and the control shaft 1501 will contact the protrusion 19 during the movement; the inclined plate 20 is fixedly mounted on the front side of the bottom of the placement plate 5, and the control shaft 1501 will contact the inclined plate 20 during the movement, and the bottom of the inclined plate 20 is low at the front and high at the back.

[0034] After the cutting of the lens raw material plate is completed, the second motor 16 is started, and the gear 17 cooperates with the gear row 18 to control the sliding frame 15 to move forward. First, the control shaft 1501 on the sliding frame 15 contacts the protrusion 19, and the control shaft 1501 squeezes the protrusion 19 to move upward, so that the placement plate 5 moves upward, and the placement plate 5 falls after the control shaft 1501 is separated from the protrusion 19. In this way, during the contact between the control shaft 1501 and the protrusion 19, the placement plate 5 will be vibrated to assist the separation of the lenses, so that the lenses can fall off better, and then fall into the receiving frame 12, slide downward along the bottom of the receiving frame 12, and finally be uniformly collected from the position of the discharge port 1201; thereafter, the control shaft 1501 continues to move forward and contacts the inclined plate 20. Through the action of the inclined plate 20, the placement plate 5 is rotated upward, and the placement plate 5 is tilted, so that the waste of the lens raw material plate will slide forward along the placement plate 5 and the inclined guide seat 13, and finally be uniformly collected from the front side of the processing table 1.

The suction machine 21 will suck out the smoke through the suction nozzle 22 to reduce the impact of this part of the smoke on the cutting work of the laser beam and ensure the cutting efficiency of the cutting machine; the suction nozzle 22 moves with the laser head 3, so that the smoke can be processed immediately, and the connecting tube 23 moves with the suction nozzle 22 and can be freely extended and retracted.

[0037] It should be noted that both the base frame 201 and the cross frame 202 are equipped with built-in moving components. The moving component on the base frame 201 can drive the cross frame 202 to move forward and backward; the moving component on the cross frame 202 can drive the moving seat 203 to move left and right; a switch is provided on the first interface 701, and when the second interface 801 is docked with the first interface 701, the switch is automatically turned on, and when the second interface 801 is separated from the first interface 701, the switch is automatically turned off to prevent the anti-reflective coating in the storage box 7 from flowing out.
