A rework method as recited in claim 1, wherein step (4) is: and (3) putting the lens with the periphery cleaned by the adhesive in the circle into an ultrasonic cleaning basket for fixing, immersing the cleaning basket with the lens after the adhesive is removed into a cleaning tank of the adhesive removing agent, and soaking and cleaning at normal temperature.
8. A rework method as recited in claim 7, wherein step (5) is:
sequentially carrying out the following procedures on the cleaning basket filled with the lens after glue removal:
immersing the substrate in a pure water tank for pure water washing;
placing the mixture into a WIN-43 alkaline cleaning agent groove of an ultrasonic cleaning machine for ultrasonic cleaning, wherein the pH value of the alkaline cleaning agent is 10 to 12, and the ultrasonic frequency is 40KHz to 60KHz;
placing the substrate in a pure water cleaning tank of an ultrasonic cleaning machine for ultrasonic cleaning, wherein the ultrasonic frequency is 40KHz to 60KHz, and the pure water resistance is 15 to 18.25MOmega;
putting the mixture into a spin-drying groove for spin-drying.
9. A rework method as recited in claim 1, wherein step (4) is: the finished lens was cleaned of surface rubs using AR grade calcium carbonate in adhesive glue at the edge.
10. A rework method as recited in claim 9, wherein step (5) is: soaking the cleaned lens in acetone, and wiping the surface of the lens with acetone and alcohol in sequence; wherein the surface of the lens is submerged by the liquid level of acetone, and the soaking time is 5-10min; the acetone soaked lens is dipped in acetone by a dust-free cloth and wiped with 2~3 times, and then dipped in alcohol by a dust-free cloth and wiped with 2 times.
