[0002] Optical glass is made by mixing oxides of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. according to a specific formula, melting at high temperature in a platinum crucible, stirring evenly with ultrasonic waves to remove air bubbles; then cooling slowly for a long time to avoid internal stress in the glass block. The cooled glass block must be measured by optical instruments to check whether its purity, transparency, uniformity, refractive index, and dispersion rate meet the specifications.

[0003] The glass edging machine is one of the earliest and most widely used mechanical equipment in glass deep-processing equipment. Its main functions are to grind the glass flat and make some special shapes. The optical lens edging machine is mainly a machine for grinding resin lenses in the eyewear industry. When using a semi-automatic lens edging machine, there will be errors in the manual grinding reference, and the reference error will cause the lens edging to deform or even damage the lens, which cannot meet the actual requirements.

[0007] By sleeving the mold lens on one end of the connector, pushing the sliding cylinder to slide rightward, rotating the second positioning bolt to fix the position of the sliding cylinder, sliding the clamping bolt, and by rotating the fastening bolt, the reference limitation is completed. Loosen the second positioning bolt to make the sliding cylinder slide leftward, and loosen the first positioning bolt and the second positioning bolt so that the first sliding frame and the second guide rod can slide up and down. Due to the action of gravity, the edge grinding operation is implemented. The eccentric adjustment mechanism can avoid the errors caused by manual operation and achieve the effect of making the semi-automatic edge grinding machine more accurate.

[0008] In a preferred embodiment, the fastening mechanism includes an internally threaded cylinder fixedly connected to one side of the first sliding frame. A fastening bolt is threadedly connected to one side of the internally threaded cylinder. One end of the fastening bolt is rotatably connected to a safety clamping rod. A safety mechanism is installed inside the safety clamping rod. One end of the safety clamping rod is equipped with a quick installation mechanism.

[0009] By rotating the fastening bolt, the internal thread on the internally threaded cylinder is used in cooperation with the external thread on the fastening bolt, so that the fastening bolt pushes the safety clamping rod to slide forward.

The module of the internal teeth is the same as that of the semi-circular gear. The rotation center of the grinding wheel and the center of the limit wheel are on the same horizontal line, and the grinding wheel and the limit wheel have the same diameter.

[0018] Under the action of gravity, the edge of the blank lens contacts the grinding wheel. Start the grinding motor to drive the grinding wheel to rotate and continuously grind the edge of the blank lens until the edge of the mold lens contacts the limit wheel. Continuously rotate the sliding handle to make the mold lens and the blank lens rotate continuously until the edge of the blank lens is ground to be the same as the mold lens.

[0030] A lens edging machine disclosed by the present invention is mainly applied to the scenario where when a semi-automatic lens edging machine is in use, there will be errors in the manually operated edging reference, and the reference error will cause the lens edging to deform or even damage the lens.

[0031] Refer to Figure 1 , Figure 2 and Figure 3, An edging machine for optical lenses, comprising a base plate 1, on the upper surface of the base plate 1, a housing 9 is fixedly connected, at the edge position near one side of the upper surface of the base plate 1, two first guide rods 2 are fixedly connected, one end of the first guide rod 2 is slidably connected with a first sliding frame 3, on one side of the first sliding frame 3, a fastening mechanism is installed, at the top edge position of one side of the housing 9, a second connecting plate 13 is fixedly connected, on one side of the second connecting plate 13, a first positioning bolt 5 is threadedly connected, at the top of the first sliding frame 3, a connecting block 14 is fixedly connected, at the top edge position of one side of the housing 9, a first connecting plate 12 is fixedly connected, at the edge position of the first connecting plate 12, a second positioning bolt 6 is threadedly connected, at the edge position near one side of the upper surface of the base plate 1, two second guide rods 8 are fixedly connected, one end of the second guide rod 8 is slidably connected with a second sliding frame 7, on one side of the second sliding frame 7, a sliding cylinder 10 is slidably connected, inside the sliding cylinder 10, an eccentric adjustment mechanism is installed, inside the sliding cylinder 10, a sliding rotation mechanism is installed, on the upper surface of the base plate 1, a horizontal grinding mechanism is installed.

[0032] In this embodiment, manual operation is required, which has some errors to a certain extent. On a semi-automatic edging machine, the error of the benchmark will cause the edging shape to deform. By sleeving the mold lens 25 on one end of the connector 20, pushing the sliding cylinder 10 to slide to the right, rotating the second positioning bolt 6 to fix the position of the sliding cylinder 10, sliding the clamping bolt 29, and by rotating the fastening bolt 4, the benchmark limitation is completed. Loosen the second positioning bolt 6 to make the sliding cylinder 10 slide to the left, loosen the first positioning bolt 5 and the second positioning bolt 6, so that the first sliding frame 3 and the second guide rod 8 can slide up and down. Due to the action of gravity, the edging operation is implemented. The eccentric adjustment mechanism can avoid the errors caused by manual operation, achieving the effect of making the semi-automatic edging machine more accurate.

[0033] Refer to Figure 1 、 Figure 2 and Figure 4 In a preferred embodiment, the fastening mechanism includes an internally threaded cylinder 15 fixedly connected to one side of the first sliding frame 3. On one side of the internally threaded cylinder 15, a fastening bolt 4 is threadedly connected. One end of the fastening bolt 4 is rotatably connected to an insurance clamping rod 17. Inside the insurance clamping rod 17, an insurance mechanism is installed. One end of the insurance clamping rod 17 is equipped with a quick installation mechanism.

[0034] In this embodiment, by rotating the fastening bolt 4, the internal thread on the internally threaded cylinder 15 cooperates with the external thread on the fastening bolt 4, so that the fastening bolt 4 pushes the insurance clamping rod 17 to slide forward.

[0035] Refer to Figure 1 、 Figure 5 and Figure 6, in a preferred embodiment, the insurance mechanism includes an insurance rod 31 slidably connected to one end of the insurance clamping rod 17. A sliding cavity 34 is provided inside the insurance clamping rod 17. A limiting groove 37 is provided on the inner wall of the internal thread cylinder 15. A retaining ring 33 is provided at one end of the insurance rod 31. A sliding spring 32 is sleeved on the insurance rod 31 near the retaining ring 33 at one end. A limiting rod 35 is slidably connected to the edge position of the sliding cavity 34 inside the insurance clamping rod 17. A limiting spring 36 is sleeved on one end of the limiting rod 35.

[0036] In this embodiment, the insurance rod 31 compresses the sliding spring 32, causing the limiting rod 35 to slide on the retaining ring 33. The limiting rod 35 slides downward, making the top end of the limiting rod 35 not exposed, enabling the insurance clamping rod 17 to continue sliding forward, ensuring that the workpiece is fully attached to one end of the insurance clamping rod 17, avoiding the situation of skewed clamping, and achieving the effect of ensuring that the workpiece does not shift during rotation. If it is not fully attached, the top end of the limiting rod 35 will be exposed, and the insurance clamping rod 17 cannot continue to slide forward.

[0037] Refer to Figure 1 、 Figure 2 and Figure 8 , in a preferred embodiment, the quick installation mechanism includes an anti-displacement disk 21 sleeved on one end of the insurance clamping rod 17. A rubber suction cup 42 is fixedly connected to one side of the anti-displacement disk 21. A mating groove 43 is provided on one side of the anti-displacement disk 21. A horizontal limiting protrusion 44 is provided in the mating groove 43. A mating hole 45 is provided on the outer wall of the horizontal limiting protrusion 44.

[0038] In this embodiment, the anti-displacement disk 21 is inserted into one end of the insurance clamping rod 17. By rotating the fastening bolt 4, the fastening bolt 4 pushes the insurance clamping rod 17 forward to squeeze the anti-displacement disk 21. The anti-displacement disk 21 will squeeze the insurance rod 31 to compress the sliding spring 32, causing the limiting rod 35 to slide on the retaining ring 33. The limiting rod 35 slides downward, making the top end of the limiting rod 35 not exposed, enabling the insurance clamping rod 17 to continue sliding forward, ensuring that the anti-displacement disk 21 and one end of the insurance clamping rod 17 are fully attached, avoiding the situation of skewed clamping, and achieving the effect of ensuring that the workpiece does not shift during rotation.

[0039] Refer to Figure 1 、 Figure 4 and Figure 5, in a preferred embodiment, the eccentric adjustment mechanism includes a semi-circular gear rack 22 slidably connected inside the sliding cylinder 10. The semi-circular gear rack 22 is composed of a plurality of semi-circular gears. Limiting rings 23 are fixedly connected to both sides of the plurality of semi-circular gears. A plurality of limiting blocks 24 are fixedly connected to the inner wall of the sliding cylinder 10. A first reference rod 38 is fixedly connected to one side of the semi-circular gear rack 22. A second reference rod 39 is fixedly connected to the outer wall of one end of the sliding cylinder 10. A sliding ring 30 is slidably connected to one side of the sliding cylinder 10. A clamping bolt 29 is threadedly connected to one side of the sliding ring 30. One end of the clamping bolt 29 is rotatably connected to a clamping internal gear 28.

[0040] The positions between the semi-circular gears are offset from each other, and the offset angle of the four semi-circular gears is 1 degree.

[0041] In this embodiment, fix the position of the sliding cylinder 10, slide the clamping bolt 29 to make the clamping internal gear 28 mesh with one of the four semi-circular gears, and rotate the clamping bolt 29 to make the clamping internal gear 28 abut against the semi-circular gear to fix the position of the semi-circular gear rack 22, so as to play the role of fixing the adjusted reference.

[0042] Refer to Figure 1 、 Figure 2 and Figure 7 , in a preferred embodiment, the sliding rotation mechanism includes an inner cylinder slidably connected to one end of the sliding cylinder 10. A sliding handle 11 is rotatably connected to one end of the inner cylinder. A limiting bolt is threadedly connected to the bottom of the sliding cylinder 10. A mold lens 25 is adsorbed at one end of the sliding handle 11. Two reference holes 41 are opened on the surface of the mold lens 25. An incomplete circular hole 40 is opened on the surface of the mold lens 25. A connector 20 is slidably connected to one side of the housing 9. A positioning suction cup 26 is fixedly connected to one end of the connector 20. A blank lens 27 is adsorbed on one side of the positioning suction cup 26.

[0043] In this embodiment, during use, the mold lens 25 needs to be processed. The mold lens 25 is a lens mold for edge grinding. Two reference holes 41 and an incomplete circular hole 40 are opened on the surface of the mold lens 25. The two reference holes 41 are respectively located on both sides of the incomplete circular hole 40. The centers of these three holes are on the same horizontal line. Based on this, the edge of the blank lens 27 is ground. Since the two reference holes 41 and the incomplete circular hole 40 are manually operated, there are some errors to a certain extent. On a semi-automatic edge grinding machine, the reference error will cause the ground shape of the blank lens 27 to be deformed. By sleeving the mold lens 25 on one end of the connector 20, pushing the sliding cylinder 10 to slide to the right, and then aligning the second reference rod 39 with one of the reference holes 41. If the two reference holes 41 and the incomplete circular hole 40 are not on the same horizontal line, the other reference hole 41 will deviate from the axis between the first reference hole 41 and the incomplete circular hole 40. At this time, by offsetting the first reference rod 38, the semi-circular gear rack 22 slides slightly, so that the first reference rod 38 passes through one of the reference holes 41. Rotate the second positioning bolt 6 to fix the position of the sliding cylinder 10. Slide the clamping bolt 29 to make the clamping internal gear 28 mesh with one of the four semi-circular gears. Rotate the clamping bolt 29 to make the clamping internal gear 28 abut against the semi-circular gear to fix the position of the semi-circular gear rack 22. The reference has been limited. Loosen the limit bolt, steady the sliding handle 11 by hand, loosen the second positioning bolt 6 to make the sliding cylinder 10 slide to the left, and the position of the sliding handle 11 remains unchanged. One end of the sliding handle 11 still abuts against the mold lens 25, so that the first reference rod 38 and the second reference rod 39 are removed from the reference holes 41. Rotate the limit bolt to abut against the inner cylinder. One end of the sliding handle 11 is also coated with glue, which can adhere to the mold lens 25. Loosen the first positioning bolt 5 and the second positioning bolt 6 to make the first sliding frame 3 and the second guide rod 8 slide up and down. Due to the action of gravity, the edge grinding starts until the edge grinding is completed.

[0044] Referring to Figure 1 , Figure 2 and Figure 4 , in a preferred embodiment, the horizontal grinding mechanism includes a grinding motor 16 fixedly connected to one side of the housing 9. One end of the output shaft of the grinding motor 16 is fixedly connected with a grinding wheel 18. One side of the housing 9 is rotatably connected with a limit wheel 19. The bottom end of the limit rod 35 contacts the surface of the safety rod 31. The retaining ring 33 is provided with a limiting groove. The designed width of the limiting groove 37 is equivalent to the cross-sectional diameter of the limit rod 35. The arc surface of the clamping internal gear 28 is provided with internal teeth. The module of the internal teeth is the same as that of the semi-circular gear. The rotation center of the grinding wheel 18 and the center of the limit wheel 19 are on the same horizontal line. The grinding wheel 18 and the limit wheel 19 have the same diameter.

[0045] In this embodiment, due to the action of gravity, the edge of the blank lens 27 contacts the grinding wheel 18. Start the grinding motor 16 to drive the grinding wheel 18 to rotate, and continuously grind the edge of the blank lens 27 until the edge of the mold lens 25 contacts the limit wheel 19. Continuously rotate the sliding handle 11 to make the mold lens 25 and the blank lens 27 rotate continuously until the edge of the blank lens 27 is ground to be the same as that of the mold lens 25. Then turn off the grinding motor 16 to stop grinding, remove the blank lens 27, and the edge grinding is completed.

[0046] Working principle: When in use, the mold lens 25 needs to be processed. The mold lens 25 is a lens mold for edging. Two reference holes 41 and an incomplete circular hole 40 are opened on the surface of the mold lens 25. The two reference holes 41 are respectively located on both sides of the incomplete circular hole 40. The centers of these three holes are on the same horizontal line. Based on this as a reference, the edge of the blank lens 27 is polished. Due to the manual operation of the two reference holes 41 and an incomplete circular hole 40, there are some errors to a certain extent. On a semi-automatic edging machine, the reference error will cause the edging shape of the blank lens 27 to be deformed. By sleeving the mold lens 25 on one end of the connector 20, pushing the sliding cylinder 10 to slide to the right, and then aligning the second reference rod 39 with one of the reference holes 41 on one side. If the two reference holes 41 and an incomplete circular hole 40 are not on the same horizontal line, the other reference hole 41 will deviate from the axis between the first reference hole 41 and the incomplete circular hole 40. At this time, by offsetting the first reference rod 38, the semi-circular gear rack 22 slides slightly, so that the first reference rod 38 passes through one of the reference holes 41. Rotate the second positioning bolt 6 to fix the position of the sliding cylinder 10. Slide the clamping bolt 29 to make the clamping internal gear 28 mesh with one of the four semi-circular gears. Rotate the clamping bolt 29 to make the clamping internal gear 28 press against the semi-circular gear to fix the position of the semi-circular gear rack 22. Find the center of the blank lens 27, align the center of the anti-displacement disk 21 with the center of the blank lens 27, adsorb the anti-displacement disk 21 on the blank lens 27, insert the anti-displacement disk 21 and the blank lens 27 into one end of the safety clamping rod 17. By rotating the fastening bolt 4, the fastening bolt 4 pushes the safety clamping rod 17 forward to squeeze the anti-displacement disk 21, so that the connector 20 abuts against the inner wall of the housing 9. The positioning suction cup 26 and the anti-displacement disk 21 clamp the blank lens 27. The anti-displacement disk 21 will squeeze the safety rod 31 to compress the sliding spring 32, so that the limiting rod 35 slides on the retaining ring 33. The limiting rod 35 slides downward so that the top end of the limiting rod 35 does not protrude, enabling the safety clamping rod 17 to continue to slide forward, ensuring that one end of the anti-displacement disk 21 and the safety clamping rod 17 are completely fitted, avoiding the situation of clamping skew, and playing a role in ensuring that the blank lens 27 does not shift during rotation. If one end of the anti-displacement disk 21 and the safety clamping rod 17 are not completely fitted, the top end of the limiting rod 35 will protrude and the safety clamping rod 17 cannot continue to slide forward. The reference has been limited. Loosen the limit bolt, hold the sliding handle 11 by hand, and loosen the second positioning bolt 6 to make the sliding cylinder 10 slide to the left.The position of the sliding handle 11 remains unchanged. One end of the sliding handle 11 still abuts against the mold lens 25, causing the first reference rod 38 and the second reference rod 39 to move out of the reference hole 41. Rotate the limit bolt to abut against the inner cylinder. One end of the sliding handle 11 is also coated with glue, which can adhere to the mold lens 25. Loosen the first positioning bolt 5 and the second positioning bolt 6 so that the first sliding frame 3 and the second guide rod 8 can slide up and down. Due to the action of gravity, the edge of the blank lens 27 contacts the grinding wheel 18. Start the grinding motor 16 to drive the grinding wheel 18 to rotate, and continuously grind the edge of the blank lens 27 until the edge of the mold lens 25 contacts the limit wheel 19. Continuously rotate the sliding handle 11 to make the mold lens 25 and the blank lens 27 rotate continuously until the edge of the blank lens 27 is ground to be the same as the mold lens 25. Turn off the grinding motor 16 to stop grinding, remove the blank lens 27, and the edge grinding is completed.,
