Description

Glass plate surface darkroom inspection system and inspection method Technical Field The application relates to the field of glass plate defect detection, in particular to a glass plate surface darkroom inspection system and a glass plate surface darkroom inspection method. Background The scratch problem of the glass plate caused by the failure of a production line or other bad reasons cannot be avoided in the production process of the glass plate, and after the scratch problem occurs, the quality bad condition of a manufacturer at the downstream of the glass plate in the production process of coating and the like can be avoided. Therefore, the manufacturers for producing the glass plates need to attach special importance to scratches in the production process, and the scratches are checked in time and treated in time so as to avoid quality problems caused by scratch defective products. For this reason, sampling inspection is often adopted to confirm whether quality problems occur during the production process, and currently, the spot inspection work on the glass sheet in the related art is directly performed on the glass transfer trolley, that is, the glass sheet is placed on the trolley, and then light is irradiated into the glass sheet in the directions of opposite directions at the upper and lower ends of the glass sheet, so that the whole glass sheet is illuminated, and based on this, the spot inspection personnel can perform visual inspection on the glass sheet by observing the surface of the glass sheet. However, this method still has disadvantages in that, firstly, when the glass plate is placed on the trolley, the lower end of the glass plate is rested on the trolley, so that the portion of the lower end of the glass plate supported by the trolley is covered, the light source at the lower end is difficult to irradiate the area, and therefore, the glass plate needs to be continuously moved relative to the trolley, so that the covered area of the glass plate is changed, and the glass plate is easily scratched in the process of moving the glass plate, and secondly, when the glass plate is placed on the trolley, the trolley forms a certain visual interference influence on the back side of the glass plate, so that the detection effect is still to be improved.
