Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a classification apparatus for a product,

The present invention relates to a product sorting apparatus.

In recent years, a glass substrate is used for a screen mounted on a computer monitor or a cellular phone to form an image. In recent years, sales of a plasma display panel (PDP), a liquid crystal display (LCD), and an organic light emitting diode The use of glass substrates is also rapidly increasing.

In the process of forming a glass substrate from a molding process to a final product, various causes cause defects in the glass substrate.

Here, defects refer to scratches, stains, dots, foreign substances, cracks, and the like generated on the glass substrate. If defects are present in the glass substrate, the entire display performance is degraded.

Conventionally, a surface inspection of a glass substrate is performed by a human operator. This is because a surface of an object to be inspected is inspected and then the object to be inspected is turned over to inspect the back surface.

In addition, inspection by the naked eye of the operator is inaccurate, and there is a problem that it takes a lot of inspection time to discriminate the failure of the glass substrate.

In this way, the mass-produced products must undergo a product testing process to check whether the product maintains its normal appearance before shipping, and it is essential that the process of selecting only the normal products after determining whether the products are sold or not.

In addition, a sorting system that automates a series of processes for sorting and sorting good products after inspecting the product has been developed and put into practical use.

A technology for inspecting a defect using a camera as a method of improving the inspection method is disclosed. More specifically, an apparatus for determining a defect through a line scan camera and an area camera while transferring an inspection object through a conveyor is disclosed in the prior art Lt; / RTI >

In this regard, Korean Patent Registration No. 10-1514409 (filed on March 31, 2013, issued on February 04, 2013, hereinafter referred to as "prior art") has proposed a vision inspection apparatus.

Such a conventional technique is an apparatus for inspecting the presence or absence of a defect on the surface of an object to be inspected. The line camera inspection process and the area camera inspection process are separated from each other in the process of inspecting the object to be inspected. And a vision inspection apparatus capable of performing the vision inspection.

However, the prior art has a problem in that convenience and quickness are deteriorated when a good product is selected in an automated process of inspecting the presence or absence of a defect on the surface of the inspected object to detect only defects and sorting the good and defective products according to the inspection result.

In addition, there is a limitation in carrying out various inspections due to insufficient construction of the line for conveying the inspection object to the inspection area and classifying and discharging the inspection object, and as a result, the versatility is deteriorated.

The present invention has been made to solve the above problems, and it is an object of the present invention to provide a method and apparatus for detecting defects on the surface of an object to be inspected, And to provide a technique that can be utilized in various inspection apparatuses by increasing the versatility of lines for transferring and discharging objects to be inspected.
