Abstract

PURPOSE:To provide a method for automatic application for coating the surface of a substrate and enabling an automatic and uniform coating to be performed. CONSTITUTION:Lateral tables 3 on both right/left sides and an application plate 1 equipped with a movable table 2 which moves back and forth reversibly between the tables 3 are used. The application part 5 of this application plate 1 and a substrate 4 aligned on a standby part 6 and then deposited on the application part 5, are sucked using the lateral tables 3 and the movable table 2, and at the same time, an application machine 7 is moved to the surface of a substrate 4a from a start point to apply a coating to the substrate 4a. After that, the suction by the lateral table 3 is suspended and the application machine is returned to the start point with the concurrent action to advance the movable table 2. The suction by this movable table 2 is suspended, then the coated substrate 4a is sent to a next step, and at the same time, a substrate 4b in the standby part 6 moves to the application part 5.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The automatic coating method according to the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of an essential part of a coating apparatus used for carrying out a method according to an embodiment of the present invention.
4 is a cross-sectional view of the coating apparatus of FIG. 1 showing steps of a method according to an embodiment of the present invention.

The substrate 4 to which the present invention is applied, and
Examples of the coating material include a case where a high-viscosity resin such as an epoxy resin having a viscosity of about 5000 to 10000 cps is applied to a metal plate such as aluminum.

As shown in FIG. 1, a coating plate 1 of a coating apparatus used for carrying out the method according to the present invention has a side table 3 on both left and right sides, and a reversible movement between the side tables back and forth. The moving table 2 is provided. Above side table 3
A plurality of first ventilation holes 13 are formed on the surface of the, and a first ventilation path 23 is provided so as to be connected to the ventilation holes 13. A plurality of second ventilation holes 12 are formed on the surface of the moving table 2, and a second ventilation passage 22 is provided so as to be connected to the ventilation holes 12. The coating plate 1 has a coating section 5 and a standby section 6. In the present invention, the substrates 4 arranged in the standby section 6 are continuously conveyed to the coating section 5.

The coating device comprises a coating section 5 of the coating plate 1.
A coating machine 7 for coating the upper surface of the substrate 4a placed on the substrate is provided. Examples of the applicator 7 include an applicator. The coating machine 7 includes a coating machine body 7a and guide bars 7b on the left and right side surfaces of the coating machine body 7a. A fixing plate 8 is provided adjacent to the outside of the side table 3 of the coating plate 1, a groove 9 is formed in the fixing plate 8 along the side table 3, and the coating machine 7 inserted into the groove 9 is provided. Information bar 7
b moves back and forth along the groove 9.

The automatic coating method of the present invention will be described.
As shown in FIGS. 1 and 2, the substrate 4 transferred from the previous step
Are arranged in the coating section 5 and the standby section 6 of the coating plate 1. The first ventilation hole 13 of the side table 3 and the moving table 2
Suction is performed from the second vent hole 12 of the substrate 4a and the substrate 4a placed on the coating unit 5 is fixed to the side table 3 and the moving table 2. These suctions are performed by the first ventilation passage 23 and the second ventilation passage 23.
This is caused by the operation of the pumps provided in the hoses (not shown) connected to the respective ventilation passages 22. By this suction, the warp of the substrate 4a can be corrected. In the suctioned state, the coating machine 7 is moved from the starting point 10 to move the substrate 4a.
Apply to the surface of. In the present invention, since the substrate 4a is applied while sucking, the substrate 4a is not warped, and thus the substrate 4a can be applied uniformly. The present invention is particularly effective when the substrate 4 is liable to warp, for example, a thin product having a thickness of 1.0 mm or less.

Next, the suction from the first ventilation hole 13 of the side table 3 is stopped, and the moving table 2 is moved forward while returning the coating machine 7 to the starting point 10. At this time, as shown in FIG. 3, when the side table 3 is lowered, the substrate 4a does not come into contact with the side table 3 and the conveyance is smoothly performed, which is preferable. Suction from the second ventilation hole 12 of the moving table 2 that has moved forward is stopped, and the coated substrate 4a is brought to the next step. In the transportation to the next process, for example, both the left and right sides of the substrate 4 are supported by belts, and the belts are rotated and transported. Further, as the moving table 2 advances, the substrate 4b of the standby section 6 advances to the coating section 5. After that, the side table 3 is raised and returned to the original position, and the moving table 2
As shown in FIG. 4, when the substrate 4b is lowered,
Is supported by the side table 3. After moving the movable table 2 backward while descending, the movable table 2 is raised again to the original position.

As described above, when the coating plate 1 is operated, the coated substrate 4a is subjected to the next process in the standby portion 6 of the substrate 4a.
b is continuously moved to the coating section 5 and coating is automatically performed.

The present invention is not limited to the above embodiment. For example, it can be used when resist or the like is applied to the resin-made substrate 4, and when the moving table 2 moves forward, the side table 3 is not lowered but the moving table 2 and the applicator 7 are raised. May be.

[0017]

According to the automatic coating method according to the first aspect of the present invention, the substrate is placed on the coating portion while being sucked by the side table and the moving table, so that the substrate is coated, so that uniform coating can be performed. In particular, it is effective when using a thin product having a thickness of 1.0 mm or less, in which the substrate is easily warped. Further, the coated substrate can be moved to the next step, and the substrate in the standby section can be moved to the coating section to automatically perform the coating.

According to the automatic coating method of the second aspect of the present invention, in particular, since the side table descends, the substrate does not come into contact with the side table, so that the conveyance is smoothly performed.
