Film coating method and device for larger size substrate

The present invention relates to a technique for coating a film on a substrate, and more particularly to a film coating method and apparatus for a large-sized substrate.

Generally, the substrate may refer to a solar substrate used in the process of fabricating a solar panel, or a touch substrate used in the process of manufacturing a touch panel.

It is known that in the process of producing a touch panel or a solar panel, at least one layer of a film must be coated on the surface of the substrate, and the film may be an ethylene vinyl acetate copolymer (EVA) for producing Protect, insulate, block or block light. For example, in the case of a solar panel, a transparent film is usually applied to the double end or the back end surface of the substrate to provide light penetration, so that the solar cell attached to or attached to the substrate can be absorbed. Solar heat, and thereby protecting the substrate to enhance the weatherability of the solar panel.

At present, solar panels are commonly used as curtain walls for general buildings. Due to the large surface area of the curtain wall, the unit area of solar panels used as curtain walls is relatively larger. According to the knowledge, there is already demand for 3800x2500mm. A solar panel of the size of the area, designed for curtain walls.

Since the material of the film is light and soft, the film coating method commonly used in the process of a touch panel or a solar panel with a small area size is easy to make the center of the film due to the influence of a large area. The phenomenon of sagging and sagging is caused, and the coating is not flat, and bubbles are easily generated, so that it cannot be implemented on the substrate of the above large surface size.

In addition, when the film on the substrate sometimes needs to be covered by a plurality of layers, The film is contacted with a substrate (for example, a glass substrate) or with a film of the same or different materials. The above-mentioned conventional film coating method also forms an uneven coating and is easy to produce. Bubbles are equal.

In view of the above, the object of the present invention is to improve the conventional method of coating a film directly on a substrate by using a pull-on film, and when it encounters a substrate having a large surface area, it is easy to cause unevenness of the coating and easy to generate bubbles. The problem of enthalpy, and the like, further provides a film attaching method for a larger-sized substrate, the technical means comprising: arranging a retractable carrier, suspended in a flat manner adjacent to a surface of one of the substrates Then, the pull film is placed flat on the carrier, and then the carrier is wound to make the adhesive film on the carrier gradually adhere to the surface of the substrate.

In a further implementation, the invention further includes the carrier being wound in a meandering path.

The direction of the take-up carrier is opposite to the direction in which the film is pulled.

The above method can be realized by a device technology. To this end, an embodiment of the present invention provides a film attaching device for a large-sized substrate, and the technical means thereof comprises: a base, positioning the substrate, The substrate has an exposed surface; a film puller includes a pull film claw disposed above the base plate, the pull film claw can reciprocate horizontally above the surface of the substrate; and a retractor comprising two slides a guiding belt disposed at the double end of the base plate, the guiding belt is coupled with a carrier member, the guiding belt can drive the carrier to move, and the carrier is suspended adjacent to the surface of the substrate and located at the pulling claw Bottom, the pull-tab can pull the film on the carrier piece, and the retractor can gradually retract the carrier to one side of the base and away from the substrate surface, so that the carrier is on the carrier The film is gradually attached to the surface of the substrate.

In a further implementation, the present invention further includes: a collecting area on one side of the base, the retractor further comprising a roll The winding wheel set is composed of a plurality of rollers arranged up and down, and the guiding belt is wound around the winding wheel set for winding the carrier to the collecting area on one side of the base. Wherein the two sides of the base are respectively provided with a network area.

The retractor retracts the carrier in a direction opposite to the direction in which the pull film pulls the film.

The two guiding belts are arranged in a loop shape and are arranged at both ends of the base.

According to the above technical means, the technical effect that can be produced by the present invention is that the retractable carrier is used as the receiving base surface before the film film, and the carrier can be wound up and asymptotically separated from the substrate. The surface characteristics enable the film placed on the carrier to be gradually and gently applied to the surface of the substrate, thereby improving the flatness of the film adhered by the larger-sized substrate and avoiding generation of bubbles after the film is applied.
