The strip dust-free cloth block 29 is pushed upward by using external force and the curvature of the strip dust-free cloth block 29 under the resistance of the lens barrel 14 and the support frame 13, so that the strip dust-free cloth block 29 squeezes the elastic sleeve 28 to shrink under the support of the toughness strip 26, thereby resetting the strip dust-free cloth block 29 and the toughness strip 26, placing the frame 25, the toughness strip 26, the connecting frame 27, the elastic sleeve 28 and the strip dust-free cloth block 29 on the support frame 13, thereby not affecting the laser engraving work of the optical glass lens;

[0124] After the wiped-off dust and impurities enter the cone sleeve 17, they will be sucked into the inner side of the transparent string plate 16 along with the air, and enter the inner side of the hollow plate 15 along the transparent string plate 16. Then, the dust and impurities will enter the inner side of the wind tube 50 through the air outlet 21 along with the air, and be blown into the inner side of the wind hood 30 through the wind tube 50, and then be blocked by the filter plate 31, and move along the filter plate 31 toward the through-hole 32, and pass through the through-hole 32 and the fixing plate 33 into the inner side of the storage bag 34 for storage, while the air will pass through the filter plate 31 and the wind hood 30 and be blown into the inner side of the connecting tube 35 and the side tube 36. The staff can unscrew the fixing parts of the fixing plate 33 to release the fixation of the fixing plate 33 according to the actual needs, and then the fixing plate 33 and the storage bag 34 can be removed, so that the impurities and dust in the storage bag 34 can be conveniently dumped.

[0139] Followers include:

[0140] The long cone head 42 is fixed to the end of the capsule 40 away from the connecting tube 35;

[0141] Infrared sensor 37, fixed on the connecting tube 35;

[0142] The rotating rod 38 penetrates the side tube 36 and is rotatably connected thereto, and is fixedly connected to the capsule tube 40;

[0143] The servo motor 39 is fixed on the outside of the side tube 36 , and the output end is connected to one end of the rotating rod 38 .

[0144] In the actual application of this embodiment, the capsule 40 can provide a stable support for the long cone head 42, and can provide a flow guide and a blowing channel for the air in the capsule 40, and the connecting tube 35 can provide a stable support for the infrared sensor 37, and the infrared sensor 37 can detect the distance between the laser engraver 10 moved above the support frame 13 and the long cone head 42, the capsule 40 can provide a stable support for the rotating rod 38, and the side tube 36 can provide a rotation support for the rotating rod 38. The servo motor 39 can drive the capsule 40 to rotate through the rotating rod 38 under the support of the side tube 36. The farther the distance between the laser engraver 10 and the long cone head 42, the greater the counterclockwise rotation angle of the servo motor 39 is controlled, and the closer the distance between the laser engraver 10 and the long cone head 42, the greater the clockwise rotation angle of the servo motor 39 is controlled, and then the elevation angle of the long cone head 42 can be controlled according to the distance between the laser engraver 10 and the long cone head 42;

[0146] When the capsule 40 rotates clockwise with the rotating rod 38 as the center, it will pull the end of the corrugated plate 45 away from the fixed guide plate 46, so that the corrugated plate 45 is stretched and elongated under the support of the fixed guide plate 46 and the connecting tube 35. At the same time, the capsule 40 will use the guide groove 43 to move along the outer side of the fixed guide plate 46 during the rotation process, so that the corrugated plate 45 is unfolded according to the clockwise rotation angle of the capsule 40, so that the unfolded corrugated plate 45 covers the opening 41 of the connecting tube 35 to prevent air from leaking to the outside through the opening 41 of the connecting tube 35. When the capsule 40 rotates counterclockwise with the rotating rod 38 as the center, it will push the unfolded corrugated plate 45 to cover the opening 41 of the connecting tube 35. The corrugated plate 45 is moved along the fixed guide plate 46 by means of the guide groove 43, so that the corrugated plate 45 is squeezed and folded to the inner side of the receiving groove 44 under the action of external force and the support of the fixed guide plate 46, and then the covered through-port 41 is opened. At this time, the through-port 41 moves to the inner side of the connecting tube 35, and at the same time, the air passing through the wind hood 30 and blowing into the inner side of the connecting tube 35 and the side tube 36 will pass through the through-port 32 and blow into the inner side of the capsule tube 40, and enter the inner side of the long cone head 42 along the capsule tube 40, and finally pass through the long cone head 42, and blow toward the optical glass lens at the laser engraving under the guidance of the long cone head 42, so as to cool the optical glass lens.

[0147] Another embodiment of the present invention provides a method for using a laser engraving device on the front of an optical glass lens, the method for using the laser engraving device comprising:

[0148] Prepare an optical glass lens, and place the optical lens into a lens tube 14 provided in the supporting member, and support the optical lens with an arc rubber strip 19;

[0149] The fan 20 provided in the air suction member is started to suck out the air in the air suction member and the supporting member to form negative pressure, and the optical glass lens is positioned and supported in the support frame 13 by using the negative pressure and the support of the arc rubber strip 19, and the flat panel light 12 is turned on to provide supplementary light for the optical glass lens through the transparent string plate 16 and the lens tube 14;

[0150] The electric rod 23 in the wiping part is controlled to extend, driving the strip-shaped dust-free cloth block 29 in the execution part to reciprocate and wipe the optical glass lens supported by the positioning part, and at the same time, the negative pressure is used to suck the dust and impurities into the storage bag 34 in the absorption part for collection;

[0151] Control the electric lifting platform 8 and the electric push rod 9 to move the position of the laser engraver 10, and control the XY axis electric translation platform 11 to move the flat panel lamp 12, and use the flat panel lamp 12 to drive the support frame 13 and the optical glass lens supported by the positioning support to move, so that the laser engraver 10 moves to the top of the support frame 13, and aligns the laser engraving end of the laser engraver 10 with the optical glass lens to be laser engraved, and starts the laser engraver 10 to perform laser engraving on the optical glass lens;

[0152] When the laser engraver 10 moves to the top of the support frame 13, the infrared sensor 37 arranged in the follower senses the distance of the laser engraver 10, and controls the servo motor 39 to rotate according to the distance, thereby adjusting the elevation angle of the long cone head 42. At the same time, the corrugated plate 45 arranged in the adjusting part is unfolded or retracted with the adjustment of the elevation angle, thereby controlling the size of the through hole 41 to prevent the through hole 41 from leaking when the long cone head 42 is adjusted;

[0153] The fan 20 provided in the air suction member will blow the air into the inner side of the air guide member through the filter plate 31 provided in the absorption member, and enter the inner side of the long cone head 42 through the capsule 40 provided in the air guide member, and then be blown out through the long cone head 42 onto the optical glass lens for cooling.

[0154] Working principle: before starting laser engraving, the staff needs to place the optical glass lens into the lens tube 14 on the support frame 13, start the fan 20, so that the lens tube 14, the cone sleeve 17, the cone rubber sleeve 18, the hollow plate 15 in the air suction piece, the wind tube 50 and the fan 20 cooperate to form a negative pressure in the lens tube 14, so as to use the negative pressure to firmly adsorb and position the optical glass lens to ensure that the lens will not move during the laser engraving process. After the lens is fixed, start the electric rod 23 to drive the connecting rod 24 and the frame 25 to move back and forth. The frame 25 pushes the toughness strip 26 to interact with the elastic sleeve 28, so that the strip dust-free cloth block 29 fits the surface of the lens and wipes off the dust and impurities on the lens. At the same time, through the action of negative pressure, these dust and impurities are sucked into the transparent string plate 16, and finally enter the wind tube 50 and the storage bag 34 for collection. After cleaning, the position of the flat panel light 12, the support frame 13 and the optical glass lens and the laser engraver 10 is adjusted by the XY-axis electric translation table 11 and the electric lifting table 8, and Adjust the height of the laser engraver 10 so that the laser engraving end of the laser engraver 10 is aligned with the optical glass lens that needs to be laser engraved and has been positioned. At the same time, start the flat lamp 12 to emit light for fill light. At this time, the laser engraver 10 is started to perform laser engraving on the surface of the lens. During the laser engraving process, the cold blowing part starts to work. Through the cooperation of the follower and the air guide, the cold blowing part will blow the outside air through the wind tube 50, the capsule 40 and the long cone head 42 to the lens surface at the laser engraving location, which plays a role in cooling and lowering the temperature. The infrared sensor 37 detects the distance between the laser engraver 10 and the long cone head 42, and adjusts the rotation angle of the capsule 40 and the pitch angle of the long cone head 42 through the servo motor 39, thereby controlling the blowing direction of the cold air to ensure that the lens will not be damaged due to excessive heat during the laser engraving process. After the laser engraving is completed, the device will stop automatically, and the staff can check and process the optical glass lens as needed. All dust and impurities in the laser engraving process will be sucked into the storage bag 34, and the staff can disassemble the storage bag 34 and clean it.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
