Coating device and coating method

Abstract

The invention provides a coating device and a coating method. The coating device comprises a fixed table, a coating net and a coating assembly, wherein the coating net is located on the fixed table, the coating net comprises a plurality of hole channels penetrating through the upper surface and the lower surface of the coating net, and a product to be coated is located on the surface of one side of the coating net; the coating assembly is located on the surface of the other side of the coating net; and the coating assembly coats the coating net with a coating medium, so that the coating mediumpermeates into the hole channels and makes contact with the surface of the product to be coated. The coating device is simple in structure and easy to implement and apply, uniform coating of the coating medium on the surface of the product to be coated can be completed through the coating device, meanwhile, the coating thickness is controllable, especially, the consistency of the surface coatingquality and the coating process of the product to be coated can be guaranteed in batch production, then the covering amount of each batch of coating media is the same, thus the service life of the product is prolonged, in addition, the production efficiency is high, and the method is suitable for batch and automatic production.

Description

Technical field[0001]The invention relates to the technical field of satellites, and more specifically, to a coating device and a coating method.Background technique[0002]With the development of satellite R&D and manufacturing technology, on-board electronic equipment and electronic components continue to develop in the direction of miniaturization and multi-function, resulting in the accumulation of more heat in the satellite's internal environment. Therefore, it is necessary to solve the heat dissipation problem of the equipment by coating the contact surface of the equipment and the deck with a thermally conductive coating medium during the assembly process of the satellite components.[0003]At present, the thermal coating medium coating in the domestic satellite assembly process adopts a manual operation mode. The operator applies the thermally conductive coating medium to the equipment, using a scraper and other tools to spread the thermally conductive coating medium on the equi...

AI Technical Summary

Problems solved by technology

[0004] However, in the process of manual operation, the coating of thermally conductive coating medium is performed manually. Due to personal factors, there are large differences in coating quality, and the coating thickness is uncontrollable, so the consistency of the process cannot be guaranteed. The amount of thermally conductive coating medium varies, resulting in different coverage of thermally conductive coating medium for each batch of products, and uneven heat dissipation due to manual application of thermally conductive coating medium will lead to poor heat dissipation and uneven heat dissipation, thereby affecting product life, especially for When coating larger and heavier equipment, multiple people are required to cooperate, the production efficiency is low, and it is difficult to carry out mass production and automatic production
