[0028] In one embodiment of the present invention, a motor-driven rotating disc 20 is installed in the center of the frame 10, and there are 6 groups of processing stations 21 in a circular array. The vibration disc 30 sequentially transports the PP cups to the first processing station 21 through the direct vibration conveyor 31, and is sucked and sent to the first processing station for precise positioning by the spacing and placement mechanism 40, and then the rotating disc 20 rotates to the second processing station 21, and the quantitative infusion pump 50 adds liquid, preferably delivering a quantitative amount of physiological saline, and then continues to rotate to the third processing station 21, and manually picks the contact lens wafers from the contact lens wafer rack into the PP cup to complete the disinfection and storage. Next, the rotating disc 20 continues to rotate and transports to the fourth processing station 21, and the film suction mechanism 60 sucks the sealing film to the upper surface of the PP cup, and then rotates to the fifth processing station 21, and the hot pressing mechanism 70 completes the hot pressing and sealing, and the sealed storage; finally, the PP cup is sucked by the cup suction mechanism 80 to the transmission belt 93 for transportation out.

[0029] Preferably, the processing station 21 is provided with 5 lower mold cavities for carrying PP cups, which are of moderate size and have high working efficiency.

[0030] Please refer to Figure 3 , Figure 3Schematic diagram of the spacing mechanism 40 of the embodiment of the present application. The spacing mechanism 40 includes a front and rear cylinder 41 mounted on a support column; a front and rear cylinder 42 driven by the front and rear cylinder 41; a mounting plate 43 driven by the front and rear cylinder 42; a guide rail 90 mounted on the lower side of the mounting plate 43; a suction cup frame 44 with a pneumatic suction cup 92 respectively matched with the guide rail 90 through a slider 91; a telescopic cylinder 45 driving each suction cup frame 44 to move horizontally; and a plurality of limit blocks 46 arranged on the mounting plate 43 to stop the suction cup frame 44.
