(3) And (5) a bonding process. Firstly, the control system controls the second visual positioning component 720 to capture, identify and position mark points of the attached lens, and transmits the specific position coordinate data of the attached lens to the control system; secondly, after the control system processes the position information, a bonding program is called, the bonded lens is subjected to vacuum adsorption by controlling the hollow vacuum adsorption plate 320, and the bonded lens is indirectly controlled to ascend and descend by controlling the vacuum adsorption plate 320 to ascend and descend through the pressing module 310; thirdly, the first visual positioning assembly 710 captures, identifies and positions mark points of the vacuum-absorbed attached lens, and compares the positioning data of the dispensing lens by the second visual positioning assembly 720 in the step (2) to complete the alignment action of the attached lens and the dispensing lens, so as to ensure that the attached lens and the dispensing lens are completely overlapped and aligned; finally, the control system controls the pressing module 310 to precisely control the bonded lens and the dispensing lens absorbed by the vacuum absorption plate 320 to complete the bonding process, so that the bonded lens and the dispensing lens completely meet the operation requirements that the deviation of the X-axis direction and the Y-axis direction is less than 10um, the deviation of the angular direction position is less than 0.001 degree, and the parallelism of the upper lens and the lower lens is less than 3 um;

(4) And (5) curing. In the process of laminating the laminated lens and the dispensing lens, when the alignment parameter, the pressure parameter and the angle parameter all reach the set parameters, the control system calls a UV curing program, the laminated lens and the dispensing lens are cured by controlling the start and stop of the curing lamp 130, and finally the UV curing process is completed;

(5) And (5) turning over. First, the horizontal movement module 941 is controlled to perform horizontal movement, and the U-shaped clamp 930 is moved to a horizontal designated position; secondly, the control system controls the vertical movement module to vertically move, moves the U-shaped clamp 930 to a vertical designated position until the U-shaped clamp 930 is placed in the U-shaped groove 114 in a matched manner, then starts the vacuum adsorption of the U-shaped clamp 930, closes the vacuum adsorption of the first adsorption hole 113, and finishes the adsorption of the U-shaped clamp 930 on the AR lens; then, the control system drives the U-shaped clamp 930 to adsorb and clamp the AR lens to return to the initial position in the vertical direction by controlling the vertical movement module; then, the control system drives the U-shaped clamp 930 to drive the AR lens to rotate 180 ° by controlling the flipping motor 910, thereby completing the flipping operation of the AR lens; finally, the control system controls the vertical movement module to vertically move, moves the U-shaped fixture 930 with the lens into the U-shaped groove 114, opens the vacuum adsorption of the first adsorption hole 113, and then closes the vacuum adsorption of the U-shaped fixture 930, so that the inverted AR lens is adsorbed and fixed;

(6) And (5) repeating the steps (1) to (4) so as to carry out the dispensing action and the laminating action on the turned AR lens again, thereby completing the double-sided bonding of the AR lens and greatly improving the utilization rate of the lens.
