Embodiment Construction

[0011] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0012] figure 1 It is a schematic structural view of the metal copper powder film coating equipment of the present invention, as shown in the figure, a metal copper powder film coating equipment 10 is mainly used for the film coating operation of the metal base material 12 of the cooling plate, and the metal base material 12 is copper Material, the metal substrate 12 needs to go through the surface cleaning step before coating. The surface cleaning step uses pure water grade or ultrapure water grade to minimize the particles and impurities in the coating environment and keep the overall coating environment dry . Metal copper powder film coating equipment 10 of the present invention comprises a conveying device 14, can convey metal base material 12, and conveying device 14 is a conveyor belt; A coating dev...

Abstract

The invention discloses metal copper powder film coating equipment and a coating method. The metal copper powder film coating equipment comprises a transporter, a coating device and an earthing device, wherein the coating device can provide metal copper powder and causes the metal copper powder to have positive charges, and the earthing device is connected with metal base material and guides the positive charge of the metal base material to the earth surface, so that the metal base material is charged negatively. When the metal base material is transported by the transporter and passes through the coating device, the coating device coats metal powder with the positive charges on the metal base material with negative charges; and because of the electrostatic force adsorption effect, metal copper power is coated on the metal base material. Compared with the manual coating mode, the invention is quick and convenient and is easy to control the thickness of the film.

Description

technical field [0001] The invention relates to a thin film coating and spraying technology, in particular to a metal copper powder thin film coating equipment and coating method used on a heat dissipation plate. Background technique [0002] With the rapid development of science and technology, the development focus of electronic components is light, thin and small. With the high density of electronic components, heat dissipation is an important issue that needs to be overcome at this stage. Usually, there are light-emitting diodes in electronic components. Because light-emitting diodes It has the advantages of high luminous efficiency, small size, low power consumption, long service life, unbreakable and rich color gamut. It is widely used in light sources, but it has the disadvantage of poor heat dissipation. Therefore, the existing light-emitting diodes All will be provided with a heat sink for heat dissipation. [0003] The cooling plate is usually covered with a layer...
