Problems solved by technology

[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 mi

Example Embodiment

[0011] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0012] Such as figure 1 As shown, the present invention provides a method for identifying and preventing errors in windshield glass during gluing. The windshield glass to be glued is moved to the gluing equipment through a conveyor belt until the center of the windshield glass coincides with the positioning origin of the equipment to achieve a preliminary windshield Centering recognition, the center of the windshield glass is the recognition point of windshield centering, which...

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...
