Description

Contact lens molding system {CONTACT LENS MOLDING SYSTEM}

The present invention relates to a contact lens molding system, and in particular, by improving the conventional expensive contact lens molding apparatus, the supplied upper and lower molds are carried out by a rotating means in the molding system and transferred to a heat treatment conveyor. A new type of contact lens molding system is designed to be significantly reduced.

Conventionally, before molding a contact lens, a top and bottom mold for forming a contact lens must be manufactured. After that, the upper and lower molds are transferred using a robot, and then other processes such as air injection, plasma treatment, lens material injection, and molding should be performed. Therefore, the conventional contact lens molding system should be equipped with a device for molding the upper and lower molds themselves, and because all processes for forming the contact lenses are processed by a robot, it is convenient, but due to the upper and lower molds manufacturing and contact lens molding There was a problem that it takes a long time to mold the contact lens. In addition, since the upper and lower molds for manufacturing the contact lens must be manufactured directly, there is a problem that the contact lens molding system itself is very expensive and difficult to purchase.

An object of the present invention is to improve the problems in the conventional contact lens molding system as described above, and the upper and lower molds for forming the contact lenses are separately manufactured and then transported in a predetermined case such as a cylindrical shape or a rectangular parallelepiped shape. It is to provide a new type of contact lens molding system that is made to reduce the manufacturing cost and to simplify the manufacturing process by proceeding the molding process while rotating the upper and lower molds for each process in a predetermined position on a rotating plate.

A lens material is injected between the upper and lower molds 800 and 820 to form a contact lens. This will be described later.

2 is a schematic plan view of FIG. 1, and FIGS. 3 to 5 are further side views of a contact lens molding system according to the present invention. For convenience, the pair of suction device bodies 300 are omitted in FIG. 2.

As shown in the drawing, in the present invention, a process for molding the contact lens around the rotating means 500 is performed. Various equipment is used for forming contact lenses.

The rotating means 500 has eight holes 520 formed at a concentric position from the center so as to proceed in eight steps for convenience from a to g.

First, a position of the rotating means 500 will be described. This position is the primary mold injection step. That is, a plurality of molds 800 serving as the lower molds for forming the contact lenses are mounted on the (lower) mold case 700. When a start signal for forming the contact lens is input, a driving signal is input to the suction device body 300 of FIG. 1, and the suction mechanism 322 is operated through the mold signal 700, thereby driving one mold 800 from the mold case 700. Sucks and rests at position a of the hole 520 of the rotating means 500.

After the above process, the suction device body 300 is transported back to the original position to repeat the operation of sucking the other mold 800 (the following process is repeated).

Then, when it is detected that the mold 800 is mounted at the a position through the sensor mounted below the a position, the rotary device 500 is mounted on its side by a predetermined angle (45 degrees) to the second stage position. When it is detected that the mold 800 is mounted at the position b by the sensor mounted on the lower portion of the position b and rotated by the operation of the position 440, the following operation is performed.

That is, the position b is a position for performing air cleaning, and performs a function of cleanly cleaning the surface of the mold 800 by the hollow transfer cover 1120 and the air discharge nozzle 1122 (see FIG. 3). That is, in FIG. 3, first, the edge of the hollow transfer cover 1120 covering the air discharge nozzle 1122 is positioned to press the flange 812 of the mold 800 before the air pump 1100 operates. At this time, the air discharge nozzle 1122 is a predetermined distance away from the mold (800). Thereafter, the air pump 1100 is operated to discharge air from the nozzle hole 1123 of the air discharge nozzle 1122 to clean dust that may be on the surface of the mold 800 to the outside of the air discharge nozzle 1122. Acts to release. The air discharge nozzle 1122 connected to the air pump 1100 is previously positioned at a corresponding position so as to fit the center of the corresponding hole 520 of the rotation means 500 as shown in FIG. 3. Other devices are also pre-positioned to fit in the center of the corresponding hole 520 of the rotating means 500 in advance or positioned so that it can be vertically moved upward and vertically downward.

After the end of this process, the device is returned to the pre-operation position by the signal detected by the sensor mounted at the lower position of the b position, and the rotating means 500 is rotated by a predetermined angle (45 degrees) to the third stage position. Mold 800 is transferred to position c.

Then, when it is detected that the mold 800 is transferred to the c position through the sensor mounted at the bottom of the position c, the following operation is performed through the sensor mounted at the bottom.

That is, the position c is a position at which the plasma processing is performed, and the plasma is projected onto the surface of the mold 800 by the connecting device 950 and the connecting pin 940 by the plasma processing apparatus 1000 (FIG. 5). Reference). This removes oil components that may be present on the mold 800 so that water droplets do not form on the mold 800 and absorbs water, thereby reducing the probability of defects.

After this process, the rotating means 500 is rotated by a predetermined angle (45 degrees) to the fourth stage position by a signal detected by a sensor mounted at the bottom of the c position, and thus the mold 800 is transferred to the position d.

Then, when it is detected that the mold 800 is transferred to the d position through the sensor mounted at the lower portion of the position d, the following operation is performed through the sensor signal mounted at the lower portion.

That is, the position d is a position where the lens material is input by the precision dispenser device 1200, and the compound of the predetermined component is stored in the dispenser device 1200. The dispenser device 1200 and the connection part 122 are connected to each other, and the lens material 1242 falls on the surface of the mold 800 like water droplets through the input device 1240. While falling, the lens material is evenly spread on the surface of the mold 800.

After this process is completed, the rotating means 500 is rotated by a predetermined angle (45 degrees) to a five-stage position by a signal detected by a sensor mounted under the d position, and thus the mold 800 is transferred to the position e.

Then, when it is detected that the mold 800 is transferred to the e position through the sensor mounted at the bottom of the position e, the following operation is performed through the sensor mounted at the bottom.

In other words, this position is the secondary mold injection step. That is, a plurality of molds 820 serving as upper molds for forming the contact lenses are mounted on the upper mold case 700. The driving signal is input to the suction device body 300 of FIG. 1, and the suction device 322 is operated through the suction device 322 to suck one mold 820 from the mold case 700, thereby opening the hole of the rotating means 500. 520 is seated in position e. This state is not shown in detail, but in the state in which the lens material 1242 is seated on the lower mold 800, a semicircular convex shape is formed in the same shape as the lower mold 800, and a flange 822 is formed. The upper mold 820 is positioned on the lower mold 800 and downwardly in surface contact with the flange 812 of the lower mold 800. As a result, the lens material 1242 is positioned between the upper mold 820 and the lower mold 800 and pressed by the upper mold 820 and the lower mold 800 to have a lens shape.

After this process is completed, the rotating means 500 is rotated by a predetermined angle (45 degrees) to the six-stage position by a signal detected by a sensor mounted at the lower position of e, and thus the mold 800 is transferred to the position f.

Then, when it is detected that the mold 800 is transferred to the f position through the sensor mounted at the lower portion of the position f, the following operation is performed through the sensor mounted at the lower portion.

That is, this position is horizontal adjustment to adjust the horizontal pressing the flange portion 822 of the upper mold 820 above the upper mold 820, the upper mold 820 and the lower mold 800 is combined and conveyed This is where the means 1320 are driven. The horizontal adjusting means 1320 is driven by the horizontal adjusting means driving unit 1300 mounted on the horizontal support 1340 fixed on the vertical support 1360.

After this process is completed, the rotating means 500 is rotated by a predetermined angle (45 degrees) to the seven-stage position by a signal sensed by a sensor mounted under the f position, and thus the mold 800 is transferred to the position g.

Then, if it is detected that the mold 800 is transferred to the g position through the sensor mounted at the lower portion of the position g, the following operation is performed through the sensor mounted at the lower portion.

That is, this position causes the completed mold 1500 to actuate the mold ejection means 1420 of the mold ejection apparatus 1400, and the mold ejection means 1420 through both flange portions of the mold 1500. Using the both sides of the ring 960 mounted on the lower end of the piston rod of the discharge step of transferring to the heat treatment conveyor 980 device (see Figure 5).

Through the above process, the upper and lower molds 820 and 800 are continuously injected and the lens material is injected at the same time to generate and discharge the mold 1500 for the contact lens.

The discharged mold 1500 is heat-treated and then the upper and lower molds 820 and 800 are removed to complete one contact lens.

Before using the both sides of the ring 980 in the discharge step, and then push the predetermined height by using a device movable upwardly, such as a plunger below the hole of the position, the two rings 980 may be used.
