A kind of spin-coating equipment for lens

Abstract

The invention discloses spin coating equipment for lenses. The spin coating equipment is characterized by comprising a mechanical hand, a feeding mechanism and a UV curing lamp, wherein the feeding mechanism comprises a recovery tube, a spray head and a negative pressure device; the recovery tube is used for bearing and collecting reinforcing liquid which is centrifugally thrown away from the lenses; the spray head is positioned in the recovery tube; the negative pressure device is used for spraying out the reinforcing liquid from the spray head; the recovery tube is made of lighttight materials; the mechanical hand comprises a fixing component used for fixing the lenses, a rotating component used for driving the fixing component to rotate and a moving component used for driving the fixingcomponent to move; the moving component can extend into the recovery tube and can also be lifted for leaving away the recovery tube in the process of driving the fixing component to move; the upper side of the recovery tube is glidingly connected with a lamp holder for installing the UV curing lamp; the cross section of the lamp holder is not smaller than an opening of the recovery tube; the irradiation direction of the UV curing lamp is a direction far away from the lamp holder. The spin coating equipment has the advantages that the reinforcing liquid can be effectively recovered, so that the implementation cost of spin coating reinforcement is favorably reduced.

Description

technical field [0001] The invention relates to a lens processing equipment, more specifically, it relates to a lens spin coating equipment. Background technique [0002] In the prior art, spin coating or spraying process is usually used for single-sided strengthening of lenses, but spraying requires high equipment, so the cost is high, which is not conducive to popularization and use. Although spin coating has relatively low equipment requirements, the current spin coating equipment has a large amount of strengthening liquid wasted. This is because a large amount of strengthening liquid will be thrown off due to centrifugal force during the rotation of the lens coated with strengthening liquid. Moreover, the existing spin-coating equipment cannot recycle the strengthening liquid, thereby increasing the implementation cost of spin-coating strengthening, which is not conducive to widespread use. [0003] For this reason, many manufacturers and people of insight carry out dev...

[0002] In the prior art, the single-sided enhancement of the lens usually adopts spin coating or spraying process, but spraying requires high equipment, so the cost is high, which is not conducive to popularization and use

Although spin coating has relatively low equipment requirements, the current spin coating equipment has a large amount of strengthening liquid waste, which is because a large amount of strengthening liquid will be thrown off due to centrifugal force during the rotation of the lens coated with strengthening liquid. and the existing spin coating equipment cannot recycle the strengthening liquid, thus increasing the implementation cost of spin coating strengthening, which is not conducive to widespread use

[0003] For this reason, many manufacturers and people of insight have developed and developed, but so far no ideal products have come out
