The clamping units are used to clamp and fix the ends of the optical lens blanks. It can support and fix each cutting area of ​​the optical lens blank when clamping and fixing the optical lens blank, so that after the optical lens blank is processed, the finished optical lens and waste can be quickly separated, ensuring overall processing efficiency and ensuring the optical performance and appearance quality of the optical lens. It can also support and fix each cutting area of ​​optical lens blanks of different shapes.

[0004] The above devices provide support and fixation for different cutting areas of the lens during the laser cutting process. However, after the lens of the required size is cut from the lens blank, the molten material at the cutting area cools and solidifies rapidly after being removed from the laser energy, forming tiny burrs. If these burrs are not cleaned, chipping or new cracks may occur during assembly. The above devices lack the function to handle these burrs during laser processing. Therefore, a laser processing technology for optical lenses is proposed to solve the above problems. Summary of the Invention

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 9 The present invention will be described in further detail below.

[0032] like Figures 1 to 9 As shown, an embodiment of the present invention provides a laser processing technology for an optical lens, comprising the following steps: S1. Cutting and feeding: The optical lens blank to be cut is placed in the cutting device for feeding, and the center position of the blank is fixed to expose the edge for laser cutting; S2. Laser cutting: Cutting the optical lens from the blank along the desired shape trajectory of the optical lens; S3. Deburring: Grind the cut edges of the optical lens and spray water on the ground area to cool it down and wash away the debris. S4. Finished product unloading: Separately unload the waste material after cutting and the finished optical lens; The cutting device in step S1 includes a housing 1, a three-axis module 2 inside the housing 1, a frame 3 fixedly connected to the three-axis module 2, a connecting plate 6 on the front side of the frame 3, a first round rod 7 fixedly connected to the connecting plate 6, the first round rod 7 extending into the frame 3 and rotatably connected to the frame 3, a laser gun head 8 fixedly connected to the front side of the connecting plate 6, a second round rod rotatably connected to one side of the connecting plate 6, a flexible grinding head 9 fixedly connected to one end of the second round rod, a partition 10 fixedly connected inside the housing 1, and an electric conveyor belt 11 fixedly connected to the partition 10.

[0033] In the specific implementation process, the three-axis module 2 drives the frame 3 to move, the frame 3 drives the first round rod 7 to move, the first round rod 7 drives the connecting plate 6 to move, and the connecting plate 6 drives the laser gun head 8 and the flexible grinding head 9 to move, thereby performing the purpose of cutting or grinding the optical lens during the movement. The electric conveyor belt 11 conveys the lens blank for loading and unloading. The first round rod 7 can rotate on the frame 3. In this device, the second round rod and the laser gun head 8 are placed in a mutually perpendicular posture, that is, when the laser gun head 8 performs the laser cutting task, the flexible grinding head 9 is positioned at the laser gun head 8. The flexible grinding head 9 is parallel to the horizontal plane. When grinding is required, the first round rod 7 is driven to rotate 90 degrees, causing the flexible grinding head 9 to be perpendicular to the horizontal plane, while the laser gun head 8 is parallel to the horizontal plane. This allows for quick switching between grinding and laser cutting tasks, which is beneficial for quickly carrying out deburring and grinding operations after laser cutting. The flexible grinding head 9 is made of a flexible material with elasticity to avoid damage to the optical lens during grinding. The material can be, for example, microporous polyurethane as the main body with abrasives such as alumina, or flexible silicone as the main body with ultrafine abrasives such as single crystal diamond.

[0034] The first round rod 7 is externally fixedly connected to the first bevel gear 12, and the frame 3 is fixedly connected to the first motor 13 on one side. The first motor 13 is fixedly connected to the second bevel gear 14 through the output shaft. The first bevel gear 12 is located on one side of the second bevel gear 14, and the first bevel gear 12 meshes with the second bevel gear 14.

[0035] The first motor 13 drives the second bevel gear 14 to rotate, the second bevel gear 14 drives the first bevel gear 12 to rotate, the first bevel gear 12 drives the first round rod 7 to rotate, and the first round rod 7 drives the connecting plate 6 to rotate, thereby driving the operation to switch between laser cutting and grinding operations.

[0036] The connecting plate 6 has a second motor 15 fixedly connected inside, and the second motor 15 is fixedly connected to one end of the second round rod through the output shaft.

[0037] The second motor 15 drives the second round rod to rotate, and the second round rod drives the flexible grinding head 9 to rotate, thereby realizing the deburring and grinding of the optical lens by the flexible grinding head 9.

[0038] Positioning components 4 are fixedly connected to the top and bottom of the electric conveyor belt 11. The two positioning components 4 are arranged in a mirror image symmetrically. The positioning components 4 are used to fix the optical lens blank. The bottom of the electric conveyor belt 11 is provided with a receiving component 5. The receiving component 5 is used to transfer the lens blank to be cut to the positioning component 4, and to receive the finished lens and scrap after cutting.

[0039] The electric conveyor belt 11 conveys a fixed distance, which can switch the upper and lower positions of the two positioning components 4. After all the lens blanks on a single positioning component 4 have been cut and polished, this positioning component 4 is conveyed to the lower position for unloading, while the other positioning component 4 is conveyed to the upper position for cutting and polishing, thus performing loading and unloading.

[0040] The positioning component 4 includes multiple guide boxes 41, which are arranged at equal intervals along the left and right directions on the electric conveyor belt 11. Multiple electric suction cups 42 are provided at equal intervals along the front and back directions inside the guide boxes 41. Multiple positioning plates are fixedly connected to the outside of the electric suction cups 42. The multiple positioning plates are fixedly connected to the inside of the guide boxes 41. A discharge port 43 is opened on the front side of the guide boxes 41, and the bottom of the guide boxes 41 is inclined towards the discharge port 43.

[0041] In the specific implementation process, when cutting the edge of the lens blank, the overall size of the electric suction cup 42 is smaller than the finished optical lens after cutting. The electric suction cup 42 adsorbs and fixes the center part of the lens blank. By adsorbing and fixing the center part, the cutting position can be staggered, avoiding the situation where the laser beam penetrates the lens blank and sweeps onto the electric suction cup 42. During the cutting process, the cut fragments can fall downward into the guide box 41 and roll out through the bottom slope of the guide box 41 towards the discharge port 43.

[0042] The receiving assembly 5 includes a placement frame 51, which is located below the electric conveyor belt 11. A feeding plate 52 is provided on the placement frame 51, and multiple feeding slots 53 are provided on the feeding plate 52. The multiple feeding slots 53 are arranged at equal intervals on the feeding plate 52. A first electric push rod 54 is fixedly connected to the bottom of the placement frame 51. The first electric push rod 54 is fixedly connected to the bottom of the inner cavity of the housing 1. A sliding base 55 is slidably connected to the bottom of the inner cavity of the housing 1 in the left-right direction. A waste collection frame 56 is fixedly connected to the top of the sliding base 55. The waste collection frame 56 is located on one side of the placement frame 51. The discharge direction of the waste collection frame 56 is inclined to the outside of the housing 1. The higher end of the waste collection frame 56 extends above the feeding plate 52.

[0043] In this device, multiple feeding slots 53 are correspondingly positioned below multiple electric suction cups 42 on the positioning assembly 4. During feeding, the lens blanks to be cut can be placed into the corresponding feeding slots 53 one by one. The first electric push rod 54 can drive the placement frame 51 to rise, which in turn drives the feeding plate 52 to rise. The feeding plate 52 moves the lens blanks upward until they touch the electric suction cups 42, whereupon the electric suction cups 42 work to hold the lens blanks in place. Subsequently, the placement frame 51 is driven to move downward, and the electric conveyor belt 11 transports the positioning assembly 4 with the lens blanks held in place to the upper part for cutting. The sliding base 55 can move left and right inside the housing 1. When the lens blanks are being fed, the sliding base 55 is driven to move towards the placement frame 51. The sliding base 55 also moves the waste collection frame 56 to the side of the feeding plate 52 to avoid obstructing the upward movement of the feeding plate 52. After the lens blanks are cut, the electric... The conveyor belt 11 transports the positioning component 4, which has the finished lens blank adsorbed above, to the bottom for unloading. At this time, the waste collection box 56 is driven to move above the unloading plate 52. After the guide box 41 is transported to the position with its opening facing downward, the remaining scraps cut out of the guide box 41 and not discharged through the discharge port 43 can fall downward into the waste collection box 56 under the influence of gravity. The waste collection box 56 collects them and rolls them to the outside of the housing 1, making it convenient for workers to collect them uniformly. When all the electric suction cups 42 on the positioning component 4 are aligned with the unloading grooves 53 on the unloading plate 52, the unloading plate 52 is driven to move upward again. After the finished optical lens below the electric suction cups 42 enters the unloading groove 53, the electric suction cups 42 release their adsorption on the finished optical lens, and the finished lens falls smoothly into the unloading groove 53 for centralized unloading.

[0044] Metal blocks 57 are fixedly connected to both sides of the feeding plate 52. Auxiliary plates are provided on both sides of the placement frame 51. Electromagnetic blocks 58 are fixedly connected to the side of the auxiliary plate facing the feeding plate 52. The two electromagnetic blocks 58 pass through the left and right side walls of the placement frame 51 respectively. Two guide rods 59 are fixedly connected to both sides of the placement frame 51. The guide rods 59 pass through the auxiliary plates. Two springs are fixedly connected between the two auxiliary plates and the placement frame 51. The four springs are correspondingly located on the outside of the four guide rods 59.

[0045] In the specific implementation process, an opening is formed on the front side of the placement frame 51 for the material feeding plate 52 to be pushed in and pulled out. The metal block 57 is made of a material that can be attracted by magnetism, such as iron or low carbon steel. After the material feeding plate 52 is placed in the placement frame 51, the electromagnetic block 58 is energized to attract the metal block 57. When the finished optical lens falls into the material feeding slot 53 in the material feeding plate 52 and the material feeding plate 52 needs to be removed, the electromagnetic block 58 is de-energized. At this time, the elastic force of the spring reduces the auxiliary plate and pushes it away from the metal block 57. The auxiliary plate drives the electromagnetic block 58 to move to the side of the metal plate. At this time, the material feeding plate 52 can be easily removed from the placement frame 51. This allows for the unified collection and placement of the finished optical lenses after cutting and grinding, which is more conducive to the transfer and handling by the staff.

[0046] Multiple limiting telescopic plates are fixedly connected to the bottom of the placement frame 51. All the limiting telescopic plates are fixedly connected to the bottom of the inner cavity of the housing 1. A second electric push rod 591 is fixedly connected to one side of the housing 1. One end of the second electric push rod 591 is fixedly connected to one side of the sliding base 55.

[0047] The limiting telescopic plate limits the placement frame 51, keeping it stable and vertically lifting and lowering, while the second electric push rod 591 can drive the sliding base 55 to move horizontally.

[0048] A nozzle 16 is provided on the front side of the second round rod. A stabilizing plate is fixedly connected to the front side of the connecting plate 6. The nozzle 16 passes through the stabilizing plate and is fixedly connected to the stabilizing plate. A box 17 is fixedly connected to one side of the inner cavity of the housing 1. A receiving frame 18 is fixedly connected to one side of the box 17. The receiving frame 18 passes through the partition 10 and is fixedly connected to the partition 10. The receiving frame 18 is located in front of the electric conveyor belt 11. A filter plate 19 is fixedly connected inside the box 17. A water pump 20 is fixedly connected inside the housing 1. The input end of the water pump 20 is connected to the box 17 through a pipe. The output end of the water pump 20 is connected to the nozzle 16 through a pipe. A sealing door is provided on one side of the box 17. The sealing door is connected to the box 17 through a hinge.

[0049] During grinding, nozzle 16 sprays grinding fluid onto the grinding area to promptly wash away and lubricate the grinding debris, further preventing damage caused by localized high temperatures. The discharge port 43 on the guide box 41 above the electric conveyor belt 11 is located above the receiving frame 18. The advantage of this design is that the washed-off grinding fluid mixed with the debris can pass through the discharge port 43 into the receiving frame 18, and then into the housing 17. The water pump 20... The part connected to the housing 17 via a pipeline is located on the side of the filter plate 19 away from the receiving frame 18. That is, the filter plate 19 filters and intercepts the grinding fluid entering the housing 17, separating the debris in the grinding fluid to prevent it from being re-sucked into the water pump 20. At this time, the water pump 20 can re-extract the grinding fluid filtered on one side of the filter plate 19 to the nozzle 16 and continue to perform the spray cooling operation during the grinding process, realizing the recycling of resources. After opening the sealed door, the inside of the housing 17 can be cleaned.

[0050] A rotating rod 22 is rotatably connected to the top of the inner cavity of the housing 17. Multiple mounting rings 23 are fixedly connected to the bottom of the rotating rod 22. The housing 17 is equipped with a guide pipe 24 and multiple filter cylinders 25. The guide pipe 24 and multiple filter cylinders 25 pass through the corresponding mounting rings 23 and are connected to the mounting rings 23 by threads. A third motor 26 is fixedly connected to the top of the housing 17. The third motor 26 is fixedly connected to the rotating rod 22 through the output shaft. A waste discharge pipe 21 is fixedly connected to the bottom of the housing 17. The waste discharge pipe 21 extends out of the housing 1 and is fixedly connected to the housing 1. A valve is provided on the waste discharge pipe 21.

[0051] In the specific implementation process, the third motor 26 drives the rotating rod 22 to rotate, which in turn drives the mounting ring 23 at the bottom to rotate synchronously. This switches the guide pipe 24 and each filter cylinder 25 to stop below the discharge port of the receiving frame 18 to receive or guide the debris. Multiple filter cylinders 25 can respectively receive and classify different types of debris with recycling value, achieving precise sorting and recycling of valuable debris. When debris enters, the liquid is discharged into the tank 17, while the debris is filtered and retained in the corresponding filter cylinder 25. When processing generates debris without recycling value, the third motor 26 adjusts the angle of the rotating rod 22 to precisely align and stop the guide pipe 24. Directly below the discharge port of the receiving frame 18; after being discharged through the receiving frame 18, the debris with no recycling value can be precisely guided down through the guide pipe 24, effectively preventing debris from entering the interior of each filter cartridge 25, preventing valuable filter cartridges 25 from being contaminated and mixed by ineffective debris, and finally the worthless debris can be directly discharged out through the waste discharge pipe 21 at the bottom of the box 17, completing the classification, filtration and sorting of debris; the debris with no recycling value that is filtered and intercepted by the filter plate 19 can be discharged uniformly through the waste discharge pipe 21 after the valve is opened, while the debris trapped in the filter cartridge 25 can be rotated off the mounting ring 23 for processing after the sealing door is opened, making the operation process simpler and more convenient.

[0052] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
