Wet pick-and-place lens head and its transfer device

This creation relates to a wet pick-and-place lens head and its transfer device. A spherical surface with a plurality of holes can be formed on the front end of the wet pick-and-place lens head mounted on the transfer device to absorb the lens At the same time, the spherical surface makes the lens appear bowl-shaped and fits the spherical surface to avoid damage to the lens when it is sucked. In addition, the overall wet pick-and-place lens head generates positive holes through the guide tube Wet pick-and-place lens head with pressure blowing force or suction force with negative pressure and its transfer device.

In recent years, due to the increase and youth of the global myopia population, contact lenses have become a very common choice for myopia people, as modern people pay attention to their appearance when wearing and light and comfortable feeling, compared with traditional frame glasses , When wearing traditional frame glasses, the feeling of pressure on the bridge of the nose due to heavy lenses and frames, and the inconvenience of sliding from the bridge of the nose during exercise, generally speaking, wearing contact lenses is quite safe, but because The lens is attached to the cornea and conjunctiva. If the lens is slightly damaged or flawed, it is easy to cause eye injury or uncomfortable feeling.

Therefore, the quality management of contact lenses becomes very important. Although the contact lenses are thin, the manufacturing process is quite complicated. Each production process is interlocked with each other, which will affect the yield of the finished product. When contact lenses are in quality inspection and After sterilization, the completed contact lenses must be moved from the production line to the packaging container to be packaged one by one, and the lens head is taken out from the liquid to remove the contact lens to In the packaging container, at the moment of taking out the lens, due to the influence of hydrodynamics, the drift of the contact lens will cause the position of the suction lens to be improper, and finally cause the defect of damage to the contact lens.

Therefore, how to use the innovative hardware design to effectively improve the conventional suction lens head, in the process of removing the contact lens from the liquid into the packaging container, it is difficult to accurately absorb the position of the contact lens, etc., is a related industry developer And related researchers need to continuously strive to overcome and solve the problems.

In view of this, in the conventional contact lens manufacturing process, when the contact lens moves the completed contact lens from the production line into the packaging container, the moment the contact lens sucks the lens head from the liquid to remove the contact lens, resulting in contact The drift of the glasses makes it difficult to accurately absorb the position of the contact lens and other problems. There are still many innovations and improvements in the conventional suction lens head during actual implementation. Therefore, the creator uses its rich professional knowledge and practical experience It was assisted by them, and improved, and the creation was studied and created accordingly.
