A purification solution 8 is provided in the purification box 2, and the purification solution 8 uses fat. The ventilation duct 7 is plugged into the purification box 2, and the outlet of the ventilation duct 7 is provided in the purification solution 8. A decontamination exhaust port 201 is fixedly connected to the upper surface of the purification box 2.

[0029] During use, the staff who apply green oil generally need to have a physical examination every three months, and must wear masks and protective clothing when using it, which shows the danger of the work; a number of support legs 103 and a purification box 2 are placed on the ground; the utility model adds a protection box 1, and sets the coating work in a relatively sealed space to reduce the diffusion of harmful gases; during coating, the exhaust fan 6 is turned on, and the air flow is drawn into the protection box 1 from the air inlet 101 under the action of air pressure, and then drawn into the ventilation chamber 5 from the air outlet 104 by the exhaust fan 6, and the gas in the exhaust chamber is drawn into the purification solution 8 under the action of the air pump 701 arranged outside the ventilation duct 7, and the harmful polychlorinated biphenyls in the green oil are easily soluble in fat and organic solvents, thereby achieving the purification of harmful gases, and the gas is discharged from the impurity removal exhaust port 201 after passing through the purification solution 8; the exhaust fan 6 is arranged below the protection box 1 so that it faces away from the coated side of the circuit board 14, thereby avoiding the influence on the coating.

[0030] Example 2

[0031] See also Figure 1 to Figure 2 , Figures 4 to 6 The utility model provides a technical solution: a coating device for processing electronic components, a material storage box 4 is fixedly installed in the middle of the upper surface of the protection box 1, a plurality of cylinders 9 are fixedly installed on the inner top wall of the protection box 1, the telescopic ends of the cylinders 9 are respectively fixedly connected with a sleeve assembly 11 and a return spring 10, a support 12 is fixedly installed at the lower end of the sleeve assembly 11, the sleeve assembly 11 includes a large sleeve 1101 and a sleeve column 1102, a deep groove 11011 is opened on the lower surface of the large sleeve 1101, and the sleeve column 1102 is inserted into the deep groove 11011 Inside, the large sleeve 1101 is fixedly connected to the telescopic end of the cylinder 9, the sleeve column 1102 is fixedly connected to the support 12, the sleeve assembly 11 is installed in the reset spring 10, and the end of the reset spring 10 away from the telescopic end of the cylinder 9 is fixedly connected to the support 12, and a coating wheel 13 is rotatably installed in the support 12. The support 12 includes several different specifications, and the coating wheel 13 also includes several different specifications. The support 12 and the coating wheel 13 installed on the same cylinder 9 are adapted to each other, and the storage box 4 supplies green oil to the coating wheel 13 through a hose.

[0032] When in use, the storage box 4 is filled with green oil, and the storage box 4 is connected to the coating wheel 13 through a retractable hose (the hose is not shown); when not working, under the control of the cylinder 9, the coating wheel 13 is away from the roller conveyor belt 3; when working, the circuit board 14 is placed on the roller of the roller conveyor belt 3, and the cylinder 9 with the coating wheel 13 of the corresponding size is selected according to the size of the circuit board 14. The corresponding coating wheel 13 is moved downward to a position close to the roller conveyor belt 3 by controlling the cylinder 9 to fall. At this time, the distance between the coating wheel 13 and the roller conveyor belt 3 is slightly smaller than the thickness of the circuit board 14. After the circuit board 14 moves below the coating wheel 13, the circuit board 14 squeezes the coating wheel 13, and the coating wheel 13 passes through the support member 12 transmits force to the sleeve 1102 and the return spring 10, the sleeve 1102 moves upward in the deep groove 11011, and the return spring 10 contracts, thereby providing a downward extrusion force to the circuit board 14 to ensure that the circuit board 14 is in close contact with the coating wheel 13. The circuit board 14 is driven by the roller conveyor belt 3 to achieve relative rotation with the coating wheel 13, thereby increasing the stability during coating (avoiding incomplete coating due to a gap between the coating wheel 13 and the circuit board 14); different sizes of circuit boards 14 are coated with coating wheels 13 of different specifications, thereby reducing incomplete coating caused by too small a coating wheel 13 and waste of coating liquid caused by too large a coating wheel 13, achieving differentiated treatment, and increasing processing accuracy.
