Waterproof coating device

Abstract

The invention relates to a waterproof coating device, which comprises a machine body; an atomization device and a drying unit are arranged in the machine body; the atomization device comprises an atomization box; the top part of the atomization box is provided with a seal cover body; a liquid drug holding chamber and a coating chamber which are communicated with each other are arranged in the atomization box; at least one drug pool is arranged in the liquid drug holding chamber; the bottom in the at least one drug pool is provided with an atomizer; a liquid nanometer high-molecular material is held in the at least one drug pool; one or more than one air exhaust hole is formed in the coating chamber; the one or more than one air exhaust hole is connected with an evacuating device; the atomizer, the one or more than one air exhaust hole and the evacuating device form an airflow loop. By utilizing the drying unit, atomized liquid drug is promoted to be further concentrated, and the drying rate of a coating is accelerated; the effective component content and the uniformity of the coating are improved; the simultaneous, uniform and moderate coating on the interior and the outer surface of an electronic product is facilitated to the maximum degree, and the coating effect is good.

[0002] Electronic products are widely used in people's daily life and are inseparable from people's clothing, food, housing and transportation; however, the internal components of electronic products, especially the circuit boards with precise and delicate structures, will , it will cause irreparable losses, or the product will be scrapped directly or multiple products will be disassembled and repaired, which will bring inconvenience to people

Therefore, relevant technical personnel have done research, and there are mainly two ways to coat electronic products: (1) Spray coating method: mainly the mobile electronic equipment to be processed is repeatedly sprayed with a large amount of mist in the isolation cabin Chemical spraying until the ideal spraying effect is achieved, the disadvantages are that the consumption of the chemical is too large, the cost is too high, and it is impossible to ensure that all electronic components in the electronic equipment can be effectively protected, and it is easy to cause important data interface failures. Poor contact or even failure to connect due to excessive coating; (2) Immersion coating method: completely immerse mobile electronic equipment such as mobile phones into a specific diluted water repellent solution, and then use ultrasonic waves, turbulence devices, etc. Under the action of auxiliary equipment, the method of making the chemical solution contact with all the inner and outer surfaces of the electronic equipment and form a coating, the problem is that in addition to the poor contact and failure of the interface caused by excessive coating, it is also easy to be contaminated by the chemical due to dust accumulation in the electronic equipment. Contamination of the medicament caused by taking it out, making the medicament unusable and increasing the cost
