Pretreatment apparatus for window glass adhesive application and method of the pretreatment

Abstract

To provide a pretreatment apparatus for window glass adhesive application, capable of complete automation of degreasing of an adhesive application surface, primer application thereon, inspection of the state produced by the primer application, etc. by a single robot. [MEANS FOR SOLVING PROBLEMS] There is provided an apparatus capable of pretreatment, such as primer application, by robot (6) on an adhesive application surface of window glass, comprising degreasing means for not only removing of dust and oil adhering to the adhesive application surface but also applying of a degreasing solution; primer application means (13) for applying of a primer to the adhesive application surface having the degreasing solution applied thereto by the degreasing means; and primer inspection / judging means (14) for inspecting of the state produced by the primer application conducted by the primer application means (13) and judging of the quality thereof. The above degreasing means comprises felt member (11) for removing of dust and oil adhering to the adhesive application surface and applying of the degreasing solution; felt holding means (12) for holding of the felt member (11); and felt regeneration means for regenerating of the felt member (11) held by the felt holding means (12).

Description

technical field [0001] The invention relates to a pretreatment device and method for window glass adhesive coating. Before applying adhesive to the adhesive coating surface of window glass, degreasing operation and primer coating are performed on the adhesive coating surface operation etc. Background technique [0002] At present, in the automobile body assembly process, when the window glass is adhesively fixed to the opening of the car body, before the adhesive is applied to the peripheral part of the window glass, it is used as a pretreatment process for the adhesive-coated surface. , after pre-degreasing the adhesive coating surface of the window glass with a cloth soaked in unleaded gasoline, etc., in order to enhance the affinity between the adhesive and the window glass, it is automatically coated by a robot as an adhesive auxiliary agent primer. [0003] This kind of coating operation may cause defective coatings such as gaps (casres) due to the instant solidificat...

AI Technical Summary

Problems solved by technology

[0010] However, in the pretreatment method of the adhesive-coated surface disclosed in Patent Document 1, a step of inspecting the coating state of the primer is separately provided, and the condition of the primer is inspected visually by an operator or by using an inspection device or the like. In the coating state, when the coating is found to be defective, the operator must re-coat the defective part, and there is a problem that the automation of the pre-treatment cannot be realized

In addition, when the wiping head is contaminated by dust or grease due to repeated use, the wiping spray gun for wiping treatment must be removed from the front end of the arm of the manipulator, and the wiping head must be cleaned or replaced with a new one, which is very complicated.

In addition, there is a problem that the installation space of the pretreatment process becomes larger

[0011] In addition, in the technical solution disclosed in Patent Document 2, when a coating failure is found, the operator must recoat the defective part, and an additional degreasing process is required before the primer coating, and there is a problem of pretreatment. The problem of increasing the setting space

[0012] In addition, in the technical solution disclosed in Patent Document 3, when a defective coating is found, the operator must recoat the defective part. In addition, because the degreasing and primer coating processes must be separately installed, there are also disadvantages. Dealing with the problem that the setting space becomes larger
