Windshield glass identification mistake-proofing method in gluing process

Abstract

The invention discloses a windshield glass identification mistake-proofing method in a gluing process. The windshield glass identification mistake-proofing method comprises the following steps: movingwindshield glass to be glued to a standard position, shooting an actual image of the windshield glass, acquiring actual gray values of a plurality of feature element points corresponding to feature point positions on the windshield glass of a correct model from the actual image, and identifying whether the windshield glass to be glued is the windshield glass of the correct model or not accordingto the actual gray values. According to the invention, the accuracy of automobile windshield glass identification is improved, the working hours are greatly saved, the repair working hours are reduced, the labor productivity of a general assembly workshop is improved, and the problem of identification errors is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a windshield recognition and error prevention method in the process of glue application. Background technique [0002] At present, when applying glue to the windshield of a car, it is generally used to identify whether the windshield is the correct model by using pulse signal recognition or two-dimensional X\Y direction length and width dimensions, but these two methods are for windshields with similar length and width dimensions. It is easy to identify mistakes when calling the correct target gluing program, so that the windshield glass of one model is easily recognized as another model, resulting in calling the wrong gluing program and wrong gluing track, so that the glass glue is applied or installed on the body. As a result, the glass glue is not attached to the body and water leakage occurs. Contents of the invention [0003] The object of the present inve...
