Workers hang the workpieces on the hangers. There are multiple cleaning tanks between the starting position and the end position of the chemical cleaning line, and a specific cleaning solution is placed in each cleaning tank. After the workers in the loading area have finished hanging the workpieces, the workers operate the crane to lift the hanger to the top of the specified cleaning tank, and then immerse the workpiece in the cleaning solution. After a certain period of time, the workers operate the crane to lift the hanger and lift it to the loading area. Then the workers hold a high-pressure water gun and use pure water to rinse the cleaning solution on the surface of the workpiece. After the rinsing is completed, repeat the operation and lift the workpiece to the next cleaning tank for immersion treatment. After a certain period of time, the workers operate the crane to lift the hanger and lift it to the loading area for pure water cleaning. The cycle is repeated until the cleaning is completed and the hanger is lifted to the unloading area. Finally, the workers blow dry the workpiece and remove the workpiece from the hanger.

[0055] S3, the crane hoists the rack 7 in the loading area to the cleaning tank for cleaning; after one cleaning process is completed, the crane hoists the rack 7 to the loading area, and hoists another rack 7 in the loading area to the cleaning tank for cleaning, and sprays water on the cleaned workpieces in the loading area.

[0056] S4, repeat S3 for multiple cleanings until the last clean water immersion cleaning is completed, and then the crane hoists the hanger 7 to the support frame 1 or the transfer trolley 2 in the unloading area. Push the vacant transfer trolley 2 in the loading area outward, install the hanger 7, hang the workpiece to be cleaned on the hanger 7, and then push the transfer trolley 2 to the loading area.

[0057] S5, blow dry the workpieces in the unloading area.

[0058] While the workpiece is being cleaned, the workpiece can be mounted and loaded on the transfer trolley 2 outside the loading area, which shortens the time for people to wait for objects and objects to wait for people. During the workpiece cleaning process, the workpiece must be immersed in different cleaning liquids, such as acid, alkali, clean water, etc. After each cleaning, the workpiece must be transferred to the loading area for clean water rinsing until it is immersed in clean water for the last time, and then directly transferred to the unloading area for drying in the unloading area. The transfer trolley 2 in the unloading area can also be moved outside the unloading area for drying, and the workpieces in the unloading area are unloaded during drying. The transfer trolley 2 is outside the unloading area, and while unloading, the workpieces in the unloading area are dried synchronously, which shortens the time for people to wait for objects and objects to wait for people. When loading the workpiece, the vacant transfer trolley 2 in the loading area is pushed outward, and the hanger 7 is installed, and the workpiece to be cleaned is hung on the hanger 7, and then the transfer trolley 2 is pushed to the loading area to complete the loading. After the hanger 7 is loaded into the loading area, the correcting piston cylinder 41 works to push the correcting rod 42 to move outward, and the end of the correcting rod 42 hits the pin 10 at the end of the hanger 7 to correct the positioning of the entire hanger 7, thereby ensuring the accuracy of the loading position of the hanger 7 and facilitating the hoisting of the crane.

[0059] The transfer trolley 2 is arranged between the left frame 3 and the right frame 4. The transfer trolley 2 can move outward to detach from the support frame 1, and then the hanger 7 is loaded onto the transfer trolley 2, and the workpiece is directly mounted and loaded on the transfer trolley 2 outside the loading area without the need for a narrow loading area. After the transfer trolley 2 that has completed the mounting and loading is moved to the loading area, the workpiece can be immediately hoisted and cleaned without the need to wait for loading in the loading area. In this patent application, by setting up the transfer trolley 2, the workpiece cleaning and loading and unloading can be carried out simultaneously without waiting, thereby improving the cleaning efficiency and economic benefits of the workpiece.
