[0021] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0022] Figure 1 It is a structural schematic diagram of the present invention; Figure 2 It is a structural schematic diagram of the lens feeding mechanism of the present invention; Figure 3 It is a structural schematic diagram of the fixture centering mechanism of the present invention; Figure 4 It is a structural schematic diagram of the lens detection mechanism of the present invention.

[0023] As attached Figure 1As shown, an automatic lens blackening device includes a lens conveying mechanism 1, a lens feeding mechanism 2, a lens discharging mechanism 3, a jig 4, a jig rotating mechanism 5, a CCD camera 1 6, a CCD camera 2 7, a jig centering mechanism 8, a ring inking mechanism 9, a side inking mechanism 10, a lens detection mechanism 11, a lens transfer mechanism 1 12, and a lens transfer mechanism 2 13. The outer side of the lens conveying mechanism 1 is provided with the lens feeding mechanism 2, the CCD camera 1 6, the CCD camera 2 7, the ring inking mechanism 9, the side inking mechanism 10, and the lens detection mechanism 11 in sequence. The outer side of the lens detection mechanism 11 is provided with the lens discharging mechanism 3. The lens conveying mechanism 1 is equipped with a jig rotating mechanism 5. The rotating part of the jig rotating mechanism 5 is magnetically attracted to the jig 4 by a magnet. A jig centering mechanism 8 is provided below the CCD camera 2 7. A lens transfer mechanism 12 is provided between the lens conveying mechanism 1 and the lens feeding mechanism 2. A lens transfer mechanism 2 13 is provided between the lens detection mechanism 11 and the lens discharging mechanism 3.

[0024] The lens conveying mechanism 1 includes an electrically controlled rotating platform 14 and a clamping claw 15 . The fingers of the clamping claw 15 are located above the rotating platform of the electrically controlled rotating platform 14 .

[0025] When the rotating table 14 is rotating, the two fingers of the first gripper 15 are open. When the rotating table stops rotating and a jig 4 is moved between the two fingers, the two fingers of the first gripper 15 clamp the jig 4. This prevents the jig 4 from shifting on the jig rotating mechanism 5 when a lens is placed in the jig 4.

[0026] As attached Figure 2 As shown, the lens feeding mechanism 2 has the same structure as the lens discharging mechanism 3. The lens feeding mechanism 2 includes a vertical hopper 21, a support plate 22, a support plate horizontal moving linear module 23, a support plate lifting cylinder 24, a carrier plate clamping block 25, a clamping block driving cylinder 26, a parallel clamping claw 27, and an inserting plate 28. The front and rear sides of the vertical hopper 21 are both fixed with cylinder bodies of the parallel clamping claw 27. The two fingers of the parallel clamping claw 27 are both fixed with inserting plates 28 for inserting between adjacent lens carriers. A pallet horizontal moving linear module 23 is provided below the silo 21 and the clamping block driving cylinder 26. The cylinder body of the pallet lifting cylinder 24 is fixed on the slide seat of the pallet horizontal moving linear module 23. The pallet 22 is fixed on the piston rod of the pallet lifting cylinder 24. Two opposite clamping block driving cylinders 26 are provided on one side of the vertical silo 21. A carrier clamp 25 is fixed on the piston rod of the clamping block driving cylinder 26. A positioning groove for positioning the lens carrier is provided on the inner side of the carrier clamp 25.

[0027] A stack of lens carriers stacked up and down is placed into the vertical silo 21, and the support plate 22 directly below the vertical silo 21 will support the lens carrier. Then the parallel clamps 27 on the front and back sides of the vertical silo 21 drive the plug-in plates 28 on both sides to move toward the middle until they are inserted between the two lens carriers at the bottom. At this time, the horizontal movement linear module 23 of the support plate drives the support plate 22 and a lens carrier on the support plate 22 to move horizontally, while the other lens carriers are supported on the plug-in plates 28 on both sides. After the support plate 22 moves to the bottom of the front and back carrier clamps 25, the lens carrier on the support plate 22 is moved up between the two carrier clamps 25, and finally the two clamp drive cylinders 26 drive the two carrier clamps 25 to clamp the lens carrier.

[0028] The jig rotation mechanism 5 includes a rotating disk and a motor. The motor body is fixed to the rotating table of the electrically controlled rotating platform 14, and the rotating disk is fixed to the motor's output shaft. The rotating disk is magnetically attracted to the jig 4 via magnets. Under external force, the jig 4 can move horizontally on the rotating disk. The motor drives the rotating disk and jig 4 to rotate.

[0029] As attached Figure 3 As shown, the fixture centering mechanism 8 includes a second clamp 81, an X-axis horizontal linear module 82, and a Y-axis horizontal linear module 83. The cylinder of the Y-axis horizontal linear module 83 is fixed on the slide of the X-axis horizontal linear module 82, and the second clamp 81 is fixed on the slide of the Y-axis horizontal linear module 83.

[0030] The X-axis horizontal linear module 82 can drive the second clamping jaw 81 to move horizontally forward and backward, and the Y-axis horizontal linear module 83 can drive the second clamping jaw 81 to move horizontally left and right.

[0031] The annular inking mechanism 9 includes an ink spray gun 91, a spray gun horizontal moving linear module 92, and a spray gun lifting linear module 93. The slide of the spray gun lifting linear module 93 is fixed on the cylinder body of the spray gun horizontal moving linear module 92, and the ink spray gun 91 is fixed on the slide of the spray gun horizontal moving linear module 92.

[0032] The spray gun horizontal movement linear module 92 can drive the ink spray gun 91 to move horizontally and linearly, and the spray gun lifting linear module 93 can adjust the height of the ink spray gun 91.

[0033] The side inking mechanism 10 includes a cotton head, a cotton head lifting cylinder 101, and a cotton head horizontal driving electric cylinder 102. The cotton head is fixed to the piston rod end of the cotton head horizontal driving electric cylinder 102, and the cylinder body of the cotton head horizontal driving electric cylinder 102 is fixed on the piston rod of the cotton head lifting cylinder 101.

[0034] The cotton head lifting cylinder 101 can drive the cotton head to move up and down, and the cotton head horizontal driving electric cylinder 102 can drive the cotton head to move horizontally and linearly.

[0035] As attached Figure 4 As shown, the lens detection mechanism 11 includes a suction nozzle 111, a suction nozzle lifting power cylinder 112, a suction nozzle horizontal rotation motor 113, a detection platform 114, a lateral CCD camera 115, a vertical CCD camera 116, and an electric rotating platform 117. The suction nozzle horizontal rotation motor 113 and the lateral CCD camera 115 are provided on the side of the detection platform 114, and a vertical CCD camera 116 is provided above the detection platform 114. The output shaft of the suction nozzle horizontal rotation motor 113 is connected to the cylinder body of the suction nozzle lifting power cylinder 112, and the piston rod of the suction nozzle lifting power cylinder 112 is fixed to the suction nozzle 111 through a bracket, and the detection platform 114 is fixed on the table surface of the electric rotating platform 117.

[0036] The nozzle lift cylinder 112 and nozzle horizontal rotation motor 113 drive the nozzle 111 to remove the lens from the jig 4 and place it on the inspection table 114. The electric rotation table 117 drives the inspection table 114 and the lens on it to rotate horizontally. The lateral CCD camera 115 transmits image information of the side of the lens to the PLC, and the vertical CCD camera 116 transmits the top view of the lens to the PLC, which determines whether the lens has been successfully inked.

[0037] The structures of lens transfer mechanism 12 and lens transfer mechanism 2 13 are the same. Lens transfer mechanism 12 includes suction nozzle 2 121, suction nozzle horizontal movement linear module 122, and suction nozzle lifting power cylinder 2 123. The slide seat of suction nozzle horizontal movement linear module 122 is fixed on the cylinder body of suction nozzle lifting power cylinder 2 123, and suction nozzle 2 121 is fixed on the piston rod of suction nozzle lifting power cylinder 2 123.

[0038] The nozzle horizontal movement linear module 122 can drive the second nozzle 121 to move horizontally and linearly, and the nozzle lifting power cylinder 123 can drive the second nozzle 121 to move vertically.

[0039] The working method of the present application is as follows: first, a stack of lens carriers loaded with lenses is placed into the lens feeding mechanism 2, which separates the lens carriers one by one and moves them to the removal position. Then, the suction nozzle 2 121 of the lens transfer mechanism 12 sucks the lenses and places them on the jig 4.

[0040] The lens transport mechanism 1 first rotates the jig 4 loaded with the lens beneath CCD camera 1 6. At this point, CCD camera 1 6 transmits the position information of the jig rotation mechanism 5 below to the PLC. The PLC then controls the horizontal linear motion module 92 of the inkjet gun to move the inkjet gun 91 for position compensation. The lens transport mechanism 1 then rotates the lens beneath CCD camera 2 7. The CCD camera 2 7 transmits the image position information of the jig rotation mechanism 5 and jig 4 to the PLC. The PLC then activates the X-axis horizontal linear module 82 and the Y-axis horizontal linear module 83 to drive the second clamp 81 to clamp the jig 4 and move the center of the jig 4 to the center of the rotating disk of the jig rotation mechanism 5, aligning the lens and the rotating disk.

[0041] The lens is then rotated to the annular inking mechanism 9, where the inkjet gun 91 sprays ink toward the edge of the lens. Simultaneously, the jig rotation mechanism 5 rotates the lens, completing the annular blackening process. If both sides of the lens need to be blackened, the annular inking mechanism 9 is skipped and the lens is rotated to the side inking mechanism 10. The cotton tip horizontal drive cylinder 102 moves the ink-soaked cotton tip back and forth horizontally, blackening both sides of the lens.

[0042] The black-painted lens is then transferred from the suction nozzle 111 to the inspection table 114 for inspection. After the inspection is completed, the lens transfer mechanism 2 13 loads the inspected lens into the lens loading tray of the lens discharging mechanism 3.

[0043] With the above-described preferred embodiments of the present invention as inspiration, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
