Description

Technical Field [0001] The present invention relates to an automatic color contact lens manufacturing apparatus,

The present invention relates to an automatic color contact lens manufacturing apparatus, and more particularly, to a color contact lens manufacturing apparatus capable of uniformly manufacturing all manufacturing processes including injection molding of a male contact lens from a mold injection process to a color printing process. The present invention relates to a color contact lens automatic manufacturing apparatus capable of uniformly improving the quality of a product to be produced, and also capable of mass-producing a color contact lens product in a highly efficient manner.

In general, eyeglasses or contact lenses are used as means for correcting the deteriorated visual acuity of the eyes. In the case of the contact lenses, the contact lenses are used to directly contact the cornea of the user's eyes. For the purpose of doing so.

Such contact lenses are divided into hard type and soft type lenses. In the case of hard type contact lenses, there is a disadvantage in that it is difficult to produce a foreign object and mass production, and a manufacturing cost is high. Therefore, a soft type lens A soft type contact lens is widely used in the market.

Further, the soft lens is divided into a general clear lens and a color lens depending on whether the lens is colored or not, and since the color lens is divided into 1 to 3 tones according to the number of colors to be colored,

Here, the color contact lens is manufactured so as to change the iris color by coloring the contact lens to correct the visual acuity according to the shape of the iris.

In a conventional method of manufacturing a contact lens, a certain amount of molding liquid is injected into a molding groove formed in an arm mold of a mold, and then the molding is pressed into a molding groove of the arm mold to solidify the molding liquid by heating and drying, And a contact lens in a solid state is demolded.

On the other hand, in the case of a color contact lens, unlike a general clear lens, a process of coloring a male mold prior to injection of a monomer (hereinafter referred to as a molding liquid) is added, the colored male mold is naturally dried, And the like.

However, in order to manufacture contact lenses in the past, manufacturing work of an overall product such as injecting a molding liquid into a molding groove of an arm mold or bonding a male mold to an arm mold is performed manually by a worker, There is a problem that a contact lens product with poor quality or low quality is produced by the torsional coupling when the lens is coupled. Further, there is a problem that the production cost is extremely low due to the manufacturing time, and the production cost is increased due to the increase of the labor cost due to the input of the excessive manpower.

As a prior art disclosed to solve the above problems, Korean Patent Registration No. 902658 (2009.06.05.) Discloses a lower pallet having a plurality of air holes having a hemispherical molding groove formed thereon, ; An upper pallet on which a plurality of air holes are formed in which a phase mold having a hemispherical pressing portion is disposed; A molding liquid injecting unit injecting a predetermined amount of the molding liquid through the syringe into each lower mold placed in the lower pallet; And a transfer pressurizing portion for placing a mold on the upper pallet in a respective lower mold into which the molding liquid has been injected, wherein the lower mold and the upper mold are provided with a lower mold and a lower mold, When the molding liquid is injected into the molding groove of the lower mold through the syringe, the transfer pressurizing portion transfers the upper mold placed in the upper pallet and seats in the molding groove of the lower mold into which the molding liquid has been injected, Wherein the molding liquid injected into the molding cavity is pressed by the pressing portion of the upper mold to be formed into a hemispherical shape, and an auxiliary mold having the same shape and dimensions as those of the lower mold positioned in the lower pallet is installed in the inner cavity of the upper pallet And the upper surface of the upper molding surface of the upper mold is pressed against the lower surface of the upper surface of the upper mold, A lifting rod provided with a clamp; A bush installed through the lifting rod and installed in a vertical lifting structure; And a transfer member for moving and lifting the bush through which the lift rod penetrates between the upper pallet and the lower pallet, wherein the lift rod adsorbing the upper mold through the pneumatic clamp is gradually lowered The molding liquid injected into the molding cavity of the lower mold is gradually pressed through the upper mold to form a semi-spherical shape, so that the contact lens molding device can be rapidly molded at low cost, Is known.

However, in the case of the molding apparatus for manufacturing the conventional contact lens, since only the process of molding the product through the mold coupling is mechanically automated and the drawing operation of the mold or the drawing operation of the mold assembly still depends on the manual operation, There is a problem in that it takes a lot of work time for taking in and out each piece and does not significantly affect the production amount of the product.

Further, in order to manufacture a conventional color contact lens, the process of supplying the male mold to the molding apparatus after coloring the male mold into an iris shape is manually performed, complicating the manufacturing process and requiring a long manufacturing time, There is a problem in that the defective rate in the manufacture of the color contact lens becomes large due to contamination or damage of the colored portion during the transfer of the color contact lens.

Further, in the related art, it is difficult to arrange the mold assembly at a predetermined interval between mold assemblies in the process of supplying the mold assemblies molded by the operator to the curing machine, There is a problem in that workability and productivity are deteriorated because the work is not continuously performed in the process of linking the work with the hardening work in the molding work.

Conventionally, there is no facility that can manufacture and manufacture a general clear lens and a color lens in parallel with each other, so that investment cost for constructing a separate equipment is excessively required, and in the middle of manufacturing work, This was a difficult problem.
