[0014] Compared with the prior art, the utility model has the beneficial effects as follows:

[0015] 1. Conformal coating of circuit boards refers to applying a specially formulated coating to circuit boards to protect them from environmental corrosion and improve their service life and reliability. This coating is commonly known as conformal paint, and its main functions include moisture resistance, dust resistance, and mildew resistance. There are various methods of applying conformal paint, including dip coating, brush coating, and spray coating. This utility device uses spray coating to process circuit boards. The long flexible tube is connected to the container assembly storing conformal paint in the external environment. The chamber door is opened, and the user places the circuit board to be processed into the feeding box. The drive motor is turned on, and the drive motor drives the reciprocating screw to rotate forward or backward. The lifting block will move up and down along the limit rod, which will in turn drive the paint spray head to adjust its height. The paint spray head is adjusted to a suitable height according to the actual spraying needs. When the device is spraying, the paint spray head can move up and down, which helps to expand the spraying range of the paint spray head on the circuit board, resulting in a larger area of ​​the circuit board being sprayed.

[0016] 2. When the device is spraying, both sets of chamber doors need to be closed before starting the spraying mode of the paint nozzle component. The paint will be sprayed from the nozzle on the front side of the paint nozzle component onto the circuit board inside the material box. The user can turn on the drive mode of the first motor. The first motor drives the turntable, mounting rod and material box to rotate slowly. The rotation of the material box will cause the circuit board inside to shake, which will make the circuit board be sprayed more evenly and increase the contact area between the conformal coating and the circuit board until the device completes the spraying work on the circuit board. The spraying work is completed in the spraying chamber, which can prevent paint from splashing into the external environment. This setting, through the coordinated work of the rotating mechanism and the spraying components, will enable the device to spray the circuit board fully and evenly, improving the working efficiency of the device.

[0017] 3. During spraying, excess paint sprayed from the spraying components will fall into the bottom cavity of the spraying chamber. The excess paint will also leak down the filter screen into the mounting bracket in the lower chamber, where it will be temporarily collected by the collection box. After the device is finished, the user can clean the inside of the spraying chamber or turn on the second motor. The second motor will drive the first lead screw to rotate forward, which will drive the moving block to move horizontally forward. This will cause the placement frame and the collection box to move out of the lower chamber until the collection box is moved out of the lower chamber. The user can then pull the collection box away from the placement frame to remove it from the placement frame, making it easier for the user to clean the inside of the collection box.

[0018] 4, after the completion of the cleaning of the material receiving box, the user can install the material receiving box into the placing frame plate slot, start the second motor to drive the first lead screw to rotate reversely, and then the moving block drives the placing frame plate and the material receiving box to move inwardly to the lower chamber, until the material receiving box is stored in the lower chamber, the setting facilitates the user to collect the excess paint of the device through the material collecting assembly, and is convenient for the user to clean the device, and improves the practicability of the device.
