Description

Technical Field

[0001] This utility model belongs to the field of coating technology, specifically relating to a cooling structure on a non-vacuum coating gun for a pharmaceutical solution reaction device. Background Technology

[0002] Plasma-enhanced chemical vapor deposition (PECVD) utilizes plasma generated from a gas in a plasma generator under the influence of a high-frequency alternating current. This plasma is then introduced into a reaction chamber, where reactants undergo cross-linking or polymerization under the influence of the plasma. The resulting plasma is then deposited onto the material surface under the action of a post-reaction plasma gas stream, yielding a solid thin film. PECVD offers advantages such as low deposition temperature, minimal impact on the substrate's structure and physical properties, high deposition rate, and strong film adhesion. It can prepare various metal, inorganic, and organic films and is widely used in mold manufacturing, semiconductor manufacturing, solar cells, and coating technology.

[0003] Plasma-enhanced chemical vapor deposition (PECVD) technology is most commonly used in coating equipment. Existing coating equipment typically operates in a vacuum environment. However, ion plating, developed from vacuum evaporation and sputtering coating, is a new coating technology that introduces various gas discharge methods into the vapor deposition field. The entire vapor deposition process takes place within plasma. Ion plating significantly increases the particle energy of the film layer, resulting in films with superior performance and expanding the application areas of "thin films." It is a rapidly developing and popular new technology. Currently available coating systems are primarily based on vacuum chambers to achieve the coating purpose. This method involves long coating times, high consumption of gases and chemicals, and difficulty in controlling production costs. A few use atmospheric pressure plasma plating, but the coating effect is poor, with low uniformity. The coating process uses high power and cannot be monitored in real time, leading to wasted costs due to temperature and flow rate fluctuations.

[0004] Therefore, atmospheric pressure plasma coating has emerged in recent years. However, existing technologies require the chemical solution to be injected first, atomized into droplets, then vaporized by absorbing heat in a heating mechanism, and finally ionized into plasma by a plasma gun mechanism. The plasma is then ejected from the plasma gun mechanism and undergoes a chemical reaction, forming new substances that adhere to the surface of the substrate to be coated. Existing structures are not only complex and bulky, but the high temperature after atomization and heating of the chemical solution before the plasma reaction significantly impacts the plasma chemical reaction, reducing the coating effect. Furthermore, this process typically involves long, continuous operation, and the heating chamber cannot guarantee complete vaporization of the chemical solution. The plasma stream ejected from the plasma gun head still contains some droplets of chemical solution, which directly sprays onto the workpiece surface, affecting the film quality as the plasma reacts with the chemical solution first. Therefore, the industry urgently needs better technological improvements to overcome the shortcomings of existing technologies. Summary of the Invention
