Description

[Detailed description of the invention] (Industrial application field) The invention involves applying a primer, urethane adhesive, etc. to the periphery of the windshield as a pretreatment process for attaching the windshield to the body of a vehicle such as an automobile. The present invention relates to an improvement in a device for positioning and supporting a window glass.

(Prior Art) Conventionally, as such a window glass positioning device, as disclosed in, for example, Japanese Utility Model Application Publication No. 60-54677, the window glass is moved by a plurality of support members erected on the base of the device body. A pair of positioning means are provided at both ends of the windshield in the vehicle width direction, which are supported horizontally from below and are swingably provided at both outer positions in the vehicle width direction of the window glass supported by the respective support members. A device is known in which the window glass is positioned and supported at a proper application position by making contact with it.

(Problem to be solved by the invention) By the way, the molding precision of windshield glass for automobiles and other vehicles is generally not severe due to its molding method, so the degree of warpage will be different at both ends in the vehicle width direction. . In particular, recently there has been a trend to increase the warpage of the rear window glass at both ends in the vehicle width direction, and in this case, the degree of warpage at both ends in the vehicle width direction becomes largely different. In this way, the degree of warpage of the windshield in the vehicle width direction is not set uniformly, so when the windshield is transported to the primer coating process or urethane adhesive coating process to attach it to the body of a vehicle such as an automobile, Even if the window glass is positioned using the above-mentioned conventional positioning device in each coating process, the positioning center of the windshield glass may deviate from the normal positioning center position to the side with greater warpage due to the difference in the degree of warpage at both ends of the window glass. It will be positioned in the same state. Therefore, if the positioning is done in such a misaligned manner, the primer, etc. applied to the peripheral edge of the windshield will be applied in a misaligned manner corresponding to the above-mentioned misalignment, and the primer, etc. This makes it impossible to apply primer or the like with high precision.

The present invention has been developed in view of the above, and its purpose is to place the window glass in the correct position when applying primer, etc. to the window glass in the primer application process, etc. as described above. By taking measures to properly position and support the windshield, even if the degree of warpage at both ends of the windshield in the vehicle width direction differs greatly,
It is an object of the present invention to enable accurate and reliable positioning and support, and thus to enable accurate application of a primer or the like to the window glass.

(Means for Solving the Problem) In order to achieve the above object, the solution of the present invention is to apply primer, adhesive, etc. In a positioning device for positioning a glass, the window glass is moved in the vehicle width direction by moving the window glass downwardly above the window glass supported by the window glass support means, which horizontally supports the window glass from below. A pressing means is provided for pressing both ends from above so that they are positioned at the same height. Furthermore, positioning means is provided on the outside of the window glass supported by the window glass support means for abutting against the outer end of the window glass and positioning it in the longitudinal and lateral directions. Further, a suction and holding means is provided for suctioning and holding the window glass pressed by the pressing means and positioned by the positioning means from below.

(Function) With the above configuration, in the present invention, the window glass that has been transported to the coating process to be coated with a primer etc. is supported horizontally from below by the window glass support means, and then Both end portions in the direction are pressed from above by the pressing means to be positioned at the same height, and the positioning means is brought into contact with the outer edge of the window glass to perform positioning in the front, rear, left and right directions, and then the suction holding means is used to position the ends in the downward direction. It is held by suction and positioned and supported.

Therefore, even if the degree of warpage of the window glass at both ends in the vehicle width direction is greatly different, both ends in the vehicle width direction are always set at the same height by the pressing action of the pressing means, with high accuracy. This ensures that the window glass is properly positioned and supported, and as a result, the primer or the like can be applied accurately to the window glass.
