Detailed Description
A contact lens wearing device capable of identifying front and back sides as described in conjunction with fig. 1-3, comprising an absorption mechanism 31, characterized in that: the adsorption mechanism 31 is used for adsorbing the diaphragm of the contact lens and preventing the diaphragm from falling off accidentally;
the contact lens film adsorption device is characterized in that the recognition mechanism 32 is arranged on one side of the adsorption mechanism 31, the recognition mechanism 32 comprises a limiting column 18, a metal elastic sheet 17 penetrates through the limiting column 18, one side of the metal elastic sheet 17 is respectively connected with a limiting spring 19 and a fixing spring 20, when the contact lens film is adsorbed, the contact lens film is deformed by pressing the metal elastic sheet 17, meanwhile, the main airbag is pressed, the contact lens film adsorbed on the front side cannot drop, and the contact lens film adsorbed on the back side can drop, so that the contact lens can be worn on the correct surface in a non-contact mode.
Advantageously, the suction mechanism 31 comprises an inner suction cup 12, one side of the bottom of the inner suction cup 12 is communicated with an inner gas transmission pipe 14, and the other end of the inner gas transmission pipe 14 is communicated with a main airbag 16.
Beneficially, the suction mechanism 31 is provided with a row error mechanism 33 on one side, the row error mechanism 33 includes an outer suction cup 11, one side of the bottom of the outer suction cup 11 is communicated with the plastic pipe 13, the surface of the plastic pipe 13 is symmetrically communicated with two auxiliary air bags 15, and each auxiliary air bag 15 is used for assisting suction.
Advantageously, the inner suction cup 12 is semi-arc shaped.
