[0040] The equidistant processing mechanism includes a circular mounting opening 11, which is provided on the surface of the movable plate 6 and is located above the flip groove 10. A fixed cylinder 12 is provided in the mounting opening 11, and a rotating ring 13 is rotatably connected to the bottom of the fixed cylinder 12. A driving motor 14 is fixedly installed on the inner wall surface of the fixed cylinder 12, and a driving wheel 15 is fixedly connected to the output shaft surface of the driving motor 14. The driving wheel 15 is in contact with the surface of the rotating ring 13, and an arc-shaped fixed rail 16 is fixedly connected to the surface of the rotating ring 13. The curvature of the fixed rail 16 is the same as the curvature of the surface to be processed by the workpiece 3. An arc-shaped sliding groove 17 is provided on the surface of the fixed rail 16, and a driving block 18 is slidably connected in the sliding groove 17. The laser head 7 is mounted on the surface of the driving block 18.

[0041] The disassembly mechanism includes a plurality of fixed rails 16 with different curvatures, and the fixed rails 16 with different curvatures are installed together with the fixed cylinders 12 of the same model, and the fixed cylinders 12 are threadedly connected to the installation openings 11;

[0042] The limiting mechanism includes a limiting block 19, which is fixedly connected to the surface of the fixed plate 4. The surface of the fixed plate 4 is elastically slidably connected to a sliding plate 20, which is located above the limiting block 19 and the upper end of the sliding plate 20 extends to the bottom of the movable plate 6;

[0043] The stabilizing mechanism includes two through-holes 21, which are respectively opened on the left and right sides of the mounting seat 2. The through-holes 21 pass through the mounting seat 2 and are connected with the flip groove 10. A first oblique groove 22 is opened on the inner wall surface of the through-hole 21. Straight grooves are provided at the upper and lower ends of the first oblique groove 22. A stabilizing rod 23 is provided in the through-hole 21. The stabilizing rod 23 slides laterally in the first oblique groove 22. A spring is fixedly connected to the bottom of the inner wall of the through-hole 21. An arc-shaped support rod 24 is fixedly connected to the end of the stabilizing rod 23. A limit plate 25 is elastically slidably connected to the surface of the mounting seat 2. The end of the limit plate 25 is an inclined surface and the end of the limit plate 25 is below the stabilizing rod 23. A second oblique groove 26 is opened on the surface of the limit plate 25. The sliding plate 20 slides laterally in the second oblique groove 26.

[0044] When laser processing the workpiece 3 of the spherical lens, first, it is necessary to use the rotating shaft 8 to open the two clamping rods 9, then place the workpiece 3 between the two clamping rods 9 and use the rotating shaft 8 to move the two clamping rods 9 to clamp the workpiece 3, and then it is necessary to select the fixed rail 16 with the same curvature as the workpiece 3 processing surface according to the curvature of the workpiece 3 processing surface, and then install the fixed cylinder 12 in the installation port 11. Then, when the workpiece 3 is processed, the telescopic cylinder 5 will act on the moving plate 6 to move together, and the moving plate 6 will move downward to push the sliding plate 20 to move downward together, and the sliding plate 20 will move downward together. The downward movement will cause the limit plate 25 to move closer to the stabilizing rod 23 through the second inclined groove 26, and the stabilizing rod 23 will gradually move upward under the action of the inclined surface on one side of the limit plate 25. During the upward movement of the stabilizing rod 23, it will move closer to the flip groove 10 under the action of the first inclined groove 22. The support rods 24 on both sides will contact the bottom of the workpiece 3, and the two arc-shaped support rods 24 can stably support the workpiece 3, so that the workpiece 3 remains stable during the processing, which is convenient for the stable processing of the workpiece 3. Then, when the movable plate 6 moves to the processing position, the sliding plate 20 will move to the limit plate 25. The position of the positioning block 19 is limited by the limiting block 19. During the processing of the workpiece 3, the movable plate 6 will maintain the same position. Then the driving motor 14 will drive the driving wheel 15 to rotate. The driving wheel 15 will drive the rotating ring 13 to rotate together with the fixed rail 16. The rotating ring 13 drives the fixed rail 16 to rotate together to adjust the position of the fixed rail 16. Then the driving block 18 will drive the laser head 7 to move in the sliding groove 17. The laser head 7 will process the surface of the workpiece 3. The curvature of the fixed rail 16 is the same as the curvature of the surface of the workpiece 3, which can enable the laser head 7 to perform machining on various positions of the upper surface of the workpiece 3. During the moving processing, the same distance is always maintained, and the laser head 7 can make the same processing angle on the surface of the workpiece 3, thereby ensuring the processing quality of the workpiece 3. After the processing is completed, the telescopic cylinder 5 acts on the moving plate 6 to move upward, and the sliding plate 20 and the limit plate 25 will return to their original positions under the action of elastic force. Then the stabilizing rod 23 is pushed downward, and the clamping rod 9 and the workpiece 3 can be flipped to the other side for processing. There is no need to disassemble the workpiece 3, ensuring that the workpiece 3 is in the same position, avoiding the disassembly of the workpiece 3 which will make the position of the workpiece 3 inconsistent, thereby affecting the processing effect of the workpiece 3.

[0045] During the processing of the spherical lens workpiece 3, the support rod 24 cannot fit the surface of the workpiece 3 with different curvatures when supporting the workpiece 3. As a further solution of the present invention, a soft support pad 27 is fixedly connected to the surface of the support rod 24.

[0046] During the processing of the spherical lens workpiece 3, the support rod 24 will support the workpiece 3 under the drive of the stabilizing rod 23, and the support pad 27 can first contact the bottom of the workpiece 3 during the movement of the support rod 24, and then gradually squeeze and support the workpiece 3 as the support rod 24 moves. This is beneficial for the support rod 24 to support workpieces 3 with different curvatures, and can still squeeze and support the workpiece 3 through the support pad 27, so that the workpiece 3 can remain stable during the processing process.

[0047] During the processing of the spherical lens, the position of the fixed cylinder 12 during installation cannot be determined. As a further solution of the present invention, a plurality of sliding grooves 28 are formed on the surface of the movable plate 6. The sliding grooves 28 are connected to the installation opening 11. A blocking block 29 is slidably connected to the sliding grooves 28. A plurality of limiting grooves 30 are formed on the surface of the fixed cylinder 12.

[0048] During the processing of the spherical lens, when installing the fixed cylinder 12, it is necessary to first move the blocking block 29 to the side away from the mounting port 11, and then install the fixed cylinder 12 in the mounting port 11. After the fixed cylinder 12 is rotated to the appropriate position, the blocking block 29 is moved to the limiting groove 30. The blocking block 29 will limit the fixed cylinder 12 through the limiting groove 30. On the one hand, it is beneficial to limit the installation position of the fixed cylinder 12, ensuring that the installation cylinder can be rotated and installed to the same position each time. On the other hand, it can keep the fixed cylinder 12 always fixed after the installation is completed, avoiding the movement of the fixed cylinder 12 during the processing, thereby affecting the processing of the spherical lens workpiece 3.

[0049] A laser processing method for a spherical lens, the specific steps of the method are as follows:

[0050] Step 1: First, use the clamping mechanism to mount the workpiece 3 on the surface of the mounting base 2;

[0051] Step 2: Then, according to the curvature of the workpiece 3 that needs to be processed, the disassembly and assembly mechanism is used to replace the corresponding equidistant processing mechanism;

[0052] Step 3: When the equidistant processing mechanism drives the laser head 7 to move to the processing position, the limiting mechanism limits the equidistant processing mechanism so that the equidistant processing mechanism moves to the same position each time;

[0053] Step 4: When the equidistant processing mechanism moves to the processing position, the stabilizing mechanism supports the workpiece 3 to keep the workpiece 3 stable;

[0054] Step 5: After the laser head 7 completes processing on one side of the workpiece 3, the workpiece 3 is quickly flipped over by the flipping mechanism;

[0055] Step 6: After both sides of the workpiece 3 are machined, replace the workpiece 3 and continue machining.
