At this time, the primer supply means 80 operates the air compressor 83 and the pneumatic control valve 85 to inject the primer of the primer supply cylinder 84 into the primer injection chamber 65 of the application block 40. In addition, the coating cloth supply means 30 rotates the coating cloth winding reel 31 through the driving motor 35 so that the coating cloth C wraps around the contact portion 41 of the coating block 40 and moves upwards. . Then, the primer discharged through the discharge hole 66 of the primer injection chamber 65 is permeated into the coating cloth (C).

In such a state that the primer is sufficiently absorbed in the coating cloth, the bottom surface of the edge of the glass panel G is brought into contact with the top surface of the contact portion 41 of the coating block 40 using the robot 50. Rotate in the direction. Then, the application block 40 is elastically supported by the coil spring 92 in a state where the predetermined distance is lowered downward along the support rod 91. Therefore, the primer of the coating cloth (C) in close contact with the contact portion 41 of the application block 40 is applied to the edge of the glass panel with a predetermined width. Subsequently, the robot 50 lowers the glass panel G downward and rotates the glass panel G in a horizontal direction while keeping the edge side of the glass panel in contact with the front surface of the contact portion 41 to apply a primer to the side of the glass panel. Let's do it. Finally, the robot 50 rotates in a horizontal direction while the upper surface of the glass panel is in contact with the bottom of the contact portion 41 of the application block 40 to apply the primer to the bottom of the glass panel with a predetermined width. The application process is completed. In this case, the robot 50 may vary the width of the primer applied to the top and bottom surfaces of the glass panel by appropriately adjusting the turning radius.

As described above, the present invention maintains the width of the primer applied to the glass panel accurately by automating the primer coating process, which is conventionally made by hand, to prevent poor adhesion of the mold, scratches generated during operation, and waste of materials. There is an effect that can be prevented.

In addition, the present invention has the effect of solving the problem that the adhesive strength of the synthetic resin mold is improved and the health of the worker is violated due to the use of the organic solvent because the primer is applied in a pushed state.
