Description

Lens processing system {SYSTEM FOR WORKING FOR LENS}

The present invention relates to a lens processing system, and more particularly to a lens processing system for automatically cutting and separating the gate of the injection molded injection of a plurality of lenses.

For example, an optical pickup lens used for a device that reads data recorded on a compact disc (CD) or a digital video disc (DVD) is commonly referred to as a collimator lens and an objective lens. In the pickup lens manufacturing method, the injection molding of the lens is injection molded, the lens is cut from the injection of the injected lens, the cut lens is loaded into a coating lens storage jig, and the lens storage jig Both sides of the stored lens are coated. In this way, a process of inspecting the lens that has been coated is carried out by loading only a good lens in a shipping tray.

In more detail, the lens injection process is a lens in which several lenses connected by a runner 3 are integrally molded from the material of the lens using an injection molding machine as shown in FIG. 1. It is a process of molding the injection molding (1). The above-described cutting process of the lens is a process in which an operator cuts the lens 5 from the injection molded product 1 of the lens by hand using a cutting jig and stores the lens 5 in the lens carrying jig.

In addition, the loading process is a process in which an operator picks the side surface of the lens in the lens transport jig using a vacuum tweezers, inspects the cut surface, and then loads the coating lens storage jig one by one.

In addition, the coating process is a process of coating both surfaces of the lens 5 by loading a plurality of coating lens storage jig loaded with the lens 5 to the coating apparatus.

In addition, the above-described packaging shipping step is a process of inspecting the coating film of the lens 5, and loading the good lens into a shipping tray.

In the lens manufacturing process as described above, since the cutting of the lens 5 from the injection molded product 1 of the lens is performed manually, there is a problem in that defects occur frequently when cutting the lens 5 and productivity is lowered.

In order to solve such a problem, a lens cutting device has been devised which can automatically cut the lens 5 from the injection molded product 1 of the lens.

However, although the lens 5 could be automatically cut from the injection molded product 1 by the lens cutting device devised as described above, the conveyance of the cut lens 5 is transferred by manual tweezers, for example, In addition, the structure of the device is complicated, the setting of the device is difficult, the productivity is reduced.

The present invention was devised to solve the above problems, and the setting of the device is easy, and the cut lens can be automatically transferred to prevent product defects when cutting the lens and improve the productivity to reduce the production cost. It is an object of the present invention to provide a lens processing system.
