The workpiece electroplating process takes T1. , where the time the workpiece is placed in the electroplating tank is ; The workpiece is immersed in the electroplating tank for ; The test shows that the time it takes for the workpiece to move from the electroplating tank to the loading position above the electroplating tank is ; Step 2: The workpiece is moved from the loading position above the electroplating tank to the unloading position above the cleaning seat. The time it takes for the workpiece to move from the loading position above the electroplating tank to the unloading position above the cleaning seat is ; Step 3, cleaning process: the workpiece is moved into the cleaning box from the unloading position above the cleaning seat, and the workpiece is cleaned in the cleaning box. After the workpiece is cleaned, it is moved from the cleaning box to the loading position above the cleaning seat. The duration of the workpiece cleaning process is T2. , where the time it takes for the workpiece to move from the top of the cleaning seat to the cleaning box is ; The workpiece is cleaned in the cleaning box for ; The time it takes for the workpiece to move from the cleaning box to the loading position above the cleaning seat is ; Step 4: The workpiece is moved from the loading position above the cleaning seat to the unloading position above the air drying seat. The time it takes for the workpiece to move from the loading position above the cleaning seat to the unloading position above the air drying seat is ; Step 5, air drying process: the workpiece is moved into the air drying box from the unloading position above the air drying seat, and the workpiece is air dried in the air drying box. After the workpiece is air dried, it is moved from the air drying box to the loading position above the air drying seat. The workpiece air drying process takes T3. , where the time it takes for the workpiece to move from the top of the air-drying seat to the air-drying box is ; The workpiece is dried in the air drying box for ; The time it takes for the workpiece to move from the air drying box to the loading position above the air drying seat is ; Step 6: The workpiece is moved from the loading position above the air drying seat to the unloading position above the spraying seat. The time it takes for the workpiece to move from the loading position above the air drying seat to the unloading position above the spraying seat is ; Step 7, spraying process: the workpiece is moved into the spray box from the unloading position above the spray seat, and the workpiece is sprayed in the spray box. After the workpiece is sprayed, it is moved from the spray box to the loading position above the spray seat. The workpiece spraying process takes T4. , where the time it takes for the workpiece to move from the top of the spraying seat to the spraying box is ; The workpiece is sprayed in the spray box for ; The time it takes for the workpiece to move from the spray box to the loading position above the spray seat is ; Step 8. The finished product is moved out from the loading position above the spraying seat.
