Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing.

[0028] figure 1 and 2 Shown is a coating device 10 according to the invention, which is mainly used for coating a substrate 7 onto a carrier 3 and promoting a uniform distribution of the substrate layer formed on the carrier 3 . The coating device 10 includes a base 2 and a bearing surface 2 a formed on the top end of the base 2 . The carrying surface 2 a is used to place the carrier 3 , and it can completely coincide with the contact surface of the carrier 3 . In a preferred embodiment, the carrying surface 2a is a plane for placing a glass substrate (ie, the carrier 3 ).

[0029] According to the present invention, the coating device 10 also includes a coating mechanism 4 capable of coating the object to be coated 7 mixed with magnetic particles on the surface to be coated 3a of the carrier 3, and an alternating magnetic field source arranged below the carrying surface...

Abstract

The invention relates to a coating method and a coating device. The coating method comprises the following steps: coating a to-be-coated substance mixed with magnetic particles on a to-be-coated surface of a carrier; applying an alternating magnetic field on the to-be-coated surface to promote the magnetic particles to vibrate in the to-be-coated substance so as to uniformly distribute the to-be-coated substance on the to-be-coated surface. According to the coating method and the coating device, the to-be-coated substance can be uniformly coated on the to-be-coated surface of the carrier to avoid an adverse effect caused by non-uniform distribution of the to-be-coated substance.

Description

technical field [0001] The invention belongs to the technical field of coating, and in particular relates to a coating method and a coating device. Background technique [0002] Coating methods are generally divided into roll coating methods and spray coating methods, which can apply glue or paint on substrates such as glass substrates, paper, cloth, resin or mechanical parts. Coating methods are used in a wide range of applications, such as painting of mechanical parts, manufacturing of thin films, and manufacturing of TFT glass and color filters for liquid crystal panels. [0003] At present, the object to be coated in the nozzle is usually sprayed on the carrier by means of air pressure, and the nozzle moves at a constant speed above the carrier for spraying, so as to obtain a relatively uniform layer of the object to be coated. However, when there is foreign matter in the nozzle or vibration occurs during the movement of the nozzle, the layer of the object to be coated ...
