Referring to the operation of the lens processing system according to the present invention having the configuration as described above are as follows.

Referring again to the drawings, in the lens processing system according to the present invention, firstly, the injection molding individual supply device 50 supplies the injection molding products 10 one by one to the first supply tray 31 at the rear end of the injection molding apparatus 30. . Then, the injection molding advance transport apparatus 32 installed at the bottom of the supply tray 31 moves the supply tray 31 on which the injection molding material 10, which has just been supplied, is seated, and thus the injection molding product 10 is continuously supplied.

Accordingly, the first supply tray 31 of the front end of the injection molding apparatus 30 is moved to the first supply tray 31 of the rear end, whereby the injection product 10 is injected by the individual injection device 50. It will also be supplied.

Subsequently, the injection material 10 held in the first feed tray 31 of the front end is clamped by the clamper 62c of the injection molding clamping device 60 and transferred to the working block 41 of the lower cutting device 40a. In this case, the work block 41 of the lower cutting device 40a is supplied with the injection molding 10 in a state in which the slide block 42 is transferred to the tip of the base 22.

The lower cutting device 40a supplied with the injection molding 10 moves to the lower portion of the lower cutting device 40a so as to face each other with the upper cutting device 40b along the slide device 42.

The upper cutting device 40b is then lowered by the elevating device 47. According to the lowering operation, the gate 13 of the injection molded product 10 is cut by the lower cutter 43 installed on all four sides of the work block 41 and the upper cutter 46 installed on all four sides of the elevating block 45, thereby injecting an injection product ( The lens 14 is separated from 10.

At this time, the gate 13 is cut so that the injection molded product 10 from which the lens 14 is separated is dropped into the discharge port 101 by the injection clamping device 60 and exits the system.

The lens 14 separated from the injection molding 10 transfers the lens 14 cut and placed by the first lens transfer device 70 installed on the left and right sides of the gate cutting device 40 in half. For example, the left and lower lenses 14 of the injection molded product 10 are transferred by the first lens transfer device 70 on the left side with respect to the gate cutting device 40, and the right and upper lenses of the injection molded product 10 ( 14, the first lens transfer device 70 on the right is transferred. Therefore, it is possible to transfer all of the lenses 14 cut at one time.

Accordingly, the left and right first lens transfer apparatus 70 absorbs and transfers the lens 14 to be placed on the standby tray 91. The standby tray 91 is formed in an 'L' shape to face each other. Of course, the vacuum suction device 72 of each first lens transfer device 70 is also configured in the form of an 'L'.

In addition, the first lens transfer device 70 transfers the vacuum suction device 72 operated by vacuum pressure for safe transportation of the lens 14.

The reason why the lens 14 is waiting in the standby tray 91 is to remove the cut lens 14 from the work block 41 quickly and safely. In order to store the lens 14 in the collection tray 92 from the beginning, the structure of the vacuum adsorption device 72 that adsorbs the lens 14 must be adapted to the structure of the collection tray 92, and in order to accommodate all of them at once, This is because a large and precise adsorption device and a storage and alignment device are required.

However, as in the present invention, once the lens 14 is taken out of the work block 41 at once, it is placed in the standby state in the standby tray 91, and then the standby lenses 14 are transferred one by one to the collection tray 92, thereby ensuring stability. In this case, the lens 14 may be transported to be safely stored in the collection tray 92, and the second lens transfer device 80 may be simply configured.

In this case, the second lens transfer apparatus 80 may sufficiently store the lens 14 in the standby tray 91 to the collection tray 92 by configuring only one vacuum adsorption apparatus 82.

In addition, when the lens 14 transferred by the first lens transfer apparatus 70 is placed on the standby tray 91, the second lens transfer apparatus 80 is driven.

The vacuum suction device 72 of the second lens transfer device 80 sucks the lenses 14 placed on the atmospheric tray 91 one by one and transfers them to the collection tray 92 provided on the base 22. At this time, the vacuum suction device 82 of the second lens transfer device 80 transfers the lenses 14 on the standby tray 91 to the collection tray 92 one by one. Accordingly, the collection tray 92 moves forward and backward in order to keep the transport distance of the vacuum suction device 82 constant.

For example, as shown in FIG. 5, when the collection tray 92 has two rows, the collection tray 92 of the first row does not move forward or backward. The reason is that the Y-axis feeding distance of the vacuum suction device 82 of the second lens transfer device 80 is the same, and only the X-axis feeding distance is different. Therefore, at this time, the collection tray 92 does not need to move forward or backward.

However, in order for the lens 14 to be placed on the collection tray 92 of the second row, the collection tray 92 moves forward and backward. The reason is that both the Y-axis feeding distance and the X-axis feeding distance of the vacuum suction device 82 of the second lens transfer device 80 are different. Therefore, in order to compensate for the Y-axis feed distance, it is moved to the Y axis.

When all of the lenses 14 are accommodated in the collection tray 92 in this way, the collection tray 92 that has been stored is taken out and replaced with a new collection tray 92 in which the lens 14 is not stored.

By repeatedly repeating the above operation, the lens 14 is cut and separated, and is safely transported to obtain a good quality lens 14 from the injection molding 10.

As such, the lens processing system according to the present invention can automatically process and produce all of the supply and delivery of the injection molded product 10, the separation and transfer of the lens 14 from the injection molded product 10, and the storage of the lens 14. do.
