Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of coating technology especially relates to a coating heating platform. BACKGROUND

[0002] The flat plate coating equipment has been widely applied to panel display, perovskite solar cell, hydrogen fuel cell and many other industries as a kind of way to complete film forming on the surface of sheet material. After the coating of sheet material is completed, a layer of wet film is formed on the surface of sheet material, and the next step needs to be dried and solidified.

[0003] The common method at present is to separately equip a heating table or drying oven outside the flat plate coating equipment, and the sheet material is taken down and placed in the heating table or drying oven after coating. The drying process needs to be quickly completed after the coating of sheet material is completed, and if the heating table or drying oven is independently equipped, the sheet material needs to be taken down from the coating platform after coating, and then transferred for a long distance, and the solution on the surface of sheet material has the risk of flowing in this process, and the flowing solution will affect the uniformity of coating thickness.

[0004] If the coating platform is directly heated, i.e. the heating is directly completed on the coating platform after coating, the coating platform can only select to use a metal platform, and a marble platform cannot be used. The surface flatness of the metal platform is much worse than that of the marble platform, and the long-time heating of the metal platform will further aggravate the deformation, and the deformation of the surface of the metal platform will affect the coating effect of the surface of the substrate. Moreover, the setting is equivalent to that the substrate is statically waited for heating and drying after coating, and a long time is needed to wait for the cooling of the platform after drying is completed to provide the coating opportunity for the next substrate again, and thus the production efficiency is affected.

During the preparation phase, the telescopic unit 203 is in a retracted state, and the pusher plate 204 is pulled back away from the drying platform 103 and the coating stage 102. When preparing to place the substrate 105 on the coating stage 102 at the substrate placement position, the telescopic unit 203 is first moved on the translation unit to the side of the coating stage 102, for example, until the extension line of the pusher plate 204 is behind the coating direction of the substrate 105.
