Abstract
Description
Technical Field

[0002] Aerospace electrical parts are generally made of aluminum alloy, and a cadmium plating layer is prepared on the aluminum alloy parts.

However, the zinc-nickel alloy plating layer currently does not achieve the performance of the cadmium plating layer, so further research is needed. The temperature of the chemical nickel plating working solution is usually above 90°C.

The air supply branch pipes (93) are provided in an "L"-shaped structure. The hot air blower (91) is provided below the receiving water tank (3).
10. An environmentally friendly coating method suitable for aerospace parts according to claim 1, It is characterized in that The following steps are involved: S1: When drying parts, the parts are placed inside the placement screen frame (2), and then the placement screen frame (2) is connected and installed with the insertion rod (11) on the right side using the connection component (5), and the second motor (4) is controlled to drive the rotating shaft (14) and the placement screen frame (2) to rotate, and the liquid on the parts is thrown out by the action of centrifugal force; S2: Control the first motor (7) to rotate 180 degrees, move the right side placement screen frame (2) to the top of the inner ring (10), control the electric push rod 13 to work and extend to drive the placement screen frame (2) to descend to between the outer ring (1) and the inner ring (10), and start the second motor (4) and the hot air blower (91) to work, so as to use the cooperation of the air supply component (9) and the air outlet component (8) to evenly dry the parts inside the placement screen frame (2), and then dry the parts from both the inside and outside of the placement screen frame 2 at the same time, and the second motor (4) drives the parts inside the placement screen frame (2) to rotate, so as to further achieve even drying of the parts; S3: When drying the parts in one of the placement screen frames (2), the staff puts the parts to be dried in the other placement screen frame (2), and connects and installs the parts with the insertion rod (11) by using the connection assembly (5), and then controls the second motor (4) to drive the placement screen frame (2) to rotate, and uses the centrifugal force to throw out the liquid on the parts, and then waits for drying; S4: When the drying of the components inside one of the placement net frames (2) is completed, the electric push rod (13) is controlled to extend to drive the placement net frame (2) to rise to the top of the inner ring (10), and then the first motor (7) is controlled to rotate 180 degrees to move the dried components to the right side of the electric push rod (13), and then the electric push rod (13) is controlled to extend to drive the placement net frame (2) on the left to descend to between the outer ring (1) and the inner ring (10), and the components inside the placement net frame (2) are evenly dried by the cooperation of the air supply component (9) and the air outlet component (8), and the second motor (4) is controlled to rotate to drive the placement net frame (2) on the left to rotate. While drying, the staff takes out the dried components and puts the components that need to be dried next into the placement net frame (2), and connects and installs them with the insertion rod (11) by using the connecting component (5), and controls the second motor (4) on the right to work, and uses the centrifugal force to throw out the liquid on the components, and then waits for drying, and repeats this process to achieve non-stop drying operation.
