Problems solved by technology

This operation is costly and tedious as a human operator (possibly aided by optics) searches dozens or even hundreds of glazing areas in various areas for tiny defects not detected by production line inspection systems
On the other hand, it often happens that, despite the operator's care, some defects go unnoticed or some glazing is wrongly judged to be defective
Substandard glazing can then be supplied to customers and adversely affect their own production
In addition to loss of customer trust, this situation can lead to complaints, returns and claims
The glazing that is wrongly judged to be defective will be scrapped by mistake, resulting in direct economic losses

Embodiment Construction

[0034] refer to Figure 1 to Figure 5 , a first example of glazing with appendages may be automotive glazing such as rear windows. Glazing 1000 includes a transparent mineral glass sheet 1001 and appendages 1002 . The appendage 1002 includes a peripheral encapsulation gasket 1002a, a peripheral enamel coating 1002b, and a fastening element 1002c.

[0035] The first detail II of appendage 1002 is in figure 2 and image 3 shown in. Peripheral encapsulation gasket 1002a includes injection points 2001 through which the material of the gasket is injected when peripheral injection gasket 1002a is molded. exist figure 2 , the injection point 2001 is qualified. image 3 An example of a defect of injection point 2001 is shown. Injection site 2001 includes injection residue 3001 . This residue is an example of a defect associated with appendage 1002 of glazing 1000 .

[0036] The second detail IV of appendage 1002 is in Figure 4 and Figure 5 shown in. exist Figure 4, t...

The method and system enable rapid and reliable detection of any type of defects associated with the glazing accessories, especially defects on large sized glazing. The device is particularly suitable for inspection of assembled glass on a production line.

Description

technical field [0001] The present invention relates to a method and system for inspecting vitrages with garnitures, in particular glazing for transport vehicles and for buildings. The invention makes it possible to quickly and reliably detect any type of defect related to glazing appendages, especially on large-sized glazing. The present invention is particularly suitable for glazing inspection on production lines. Background technique [0002] In addition to one or more mineral and / or organic transparent glass sheets, glazing may also include other added elements on one or more glass sheets, such as encapsulation gaskets, sealing gaskets, assembly devices, paint layers, enamels Cladding, decorative moldings, organic and / or mineral silk lacquers, prints, signs, trims, pins, metal and / or plastic inserts, antennas, etc. These additional elements constitute, in a nutshell, glazing appendages. [0003] These additional elements can perform various functions, for example seal...
