[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a clean production line for plasma coating fabrication, including a clean spraying chamber 1 and a drying production line 2. The clean spraying chamber 1 is used for spraying plasma coatings on radio frequency plasma surgical electrodes, while the drying production line 2 is located next to the clean spraying chamber 1. After the coating is sprayed in the clean spraying chamber 1, the plasma coating is dried by the drying production line 2. The clean spraying chamber 1 includes a base 11 and a coating control component 13. It should be noted that the coating control component 13 is located outside the clean spraying chamber 1 and is a coating delivery pump. The plasma coating is delivered through the coating control component 13.

[0022] A spraying chamber 12 is installed on the upper side of the base 11, and a spraying component slide rail 16 is installed at the bottom of the inner cavity of the spraying chamber 12. A universal spraying component 15 is slidably installed on the spraying component slide rail 16. The universal spraying component 15 can be adjusted by moving on the spraying component slide rail 16. The universal spraying component 15 is an angle-adjustable nozzle, and the universal spraying component 15 is connected to the paint control component 13, which facilitates the delivery of paint to the universal spraying component 15 through the paint control component 13.

[0023] An exhaust filter assembly 14, which communicates with the inner cavity, is installed on the upper side of the spraying chamber 12. The exhaust filter assembly 14 is used to filter the exhaust gas in the dust-free spraying chamber 1 to reduce the impact and pollution on the environment. A spraying product fixing rack 17 is provided inside the spraying chamber 12. The spraying product fixing rack 17 is used to place radio frequency plasma surgical electrodes so that the universal spraying assembly 15 can spray them. A temperature and humidity control device interface 18, which communicates with the inner cavity, is provided on the top of the spraying chamber 12. An air temperature and humidity regulating device is installed on the top of the dust-free spraying chamber 1, and the air temperature and humidity regulating device is connected to the inner cavity of the dust-free spraying chamber 1 through the temperature and humidity control device interface 18 to facilitate the adjustment of the temperature and humidity in the dust-free spraying chamber 1. A spraying chamber outlet is provided on the side of the spraying chamber 12 near the drying production line 2.

[0024] The dust-free spraying chamber 1 provides a clean and sealed environment with controllable temperature and humidity for plasma spraying, improving the pass rate of plasma coating spraying and ensuring the preparation quality of radio frequency plasma surgical electrodes. It also achieves automatic spraying through the set spraying component slide rail 16, universal spraying component 15 and coating control component 13, replacing the traditional manual spraying, improving the spraying efficiency and quality of surgical electrode tip, and avoiding adverse effects on personnel during the spraying process. It can effectively improve the working environment of personnel and protect their health. At the same time, the set emission filter component 14 solves the environmental pollution problem.

[0025] The drying production line 2 includes a low-temperature rise chamber 21, a low-temperature constant-temperature chamber 22, a medium-temperature rise chamber 23, a medium-temperature constant-temperature chamber 24, a high-temperature rise chamber 25, a high-temperature constant-temperature chamber 26, a curing rise chamber 27, a curing constant-temperature chamber 28, and a cooling chamber 29 arranged sequentially. The low-temperature rise chamber 21 is located near the outlet of the spraying chamber on the side of the dust-free spraying chamber 1. The arrangement of these chambers divides the temperature range of the drying production line 2 into a low-temperature rise zone, a low-temperature constant-temperature zone, a medium-temperature rise zone, a medium-temperature constant-temperature zone, a high-temperature rise zone, a high-temperature constant-temperature zone, a curing rise zone, a curing constant-temperature zone, and a cooling zone. Conveyor belts are installed inside the following warehouses: warehouse 21, low constant temperature warehouse 22, medium temperature rise warehouse 23, medium constant temperature warehouse 24, high temperature rise warehouse 25, high constant temperature warehouse 26, curing temperature rise warehouse 27, curing constant temperature warehouse 28, cooling warehouse 29, and between the low temperature rise warehouse 21 and the spraying warehouse outlet. The conveyor belts installed at the locations of low temperature rise warehouse 21, low constant temperature warehouse 22, medium temperature rise warehouse 23, medium constant temperature warehouse 24, high temperature rise warehouse 25, high constant temperature warehouse 26, curing temperature rise warehouse 27, curing constant temperature warehouse 28, and cooling warehouse 29 are all individually adjustable.

[0026] The drying temperature and time are key factors in ensuring coating quality. If the drying temperature is too high or the time is too long, the coating will be over-dried, causing cracks or embrittlement on the coating surface. If the drying temperature is too low or the time is too short, the solvents and volatile components in the coating will not evaporate completely, affecting the hardness and adhesion of the coating. In this solution, the running speed of the conveyor belt and the temperature of each temperature range are individually controlled, which makes it easy to accurately control the running speed and temperature changes during the product drying process according to the drying characteristics of the coating.

The leveling zone 3 is open and the temperature inside the leveling zone 3 is 20℃~30℃. Preferably, the temperature inside the leveling zone 3 is 25℃.

The waiting time for picking is controlled by setting the conveyor belt speed. Preferably, the temperature of the picking area is 25°C and the waiting time for picking is controlled by setting the conveyor belt speed to 5 minutes.

[0029] The front of the spraying chamber 12 is open, and a protective glass is sealed inside the opening. The protective glass allows personnel to observe the working status inside the spraying chamber 12. A manual adjustment window 19 is provided on the lower side of the protective glass.
