The PLC controls the repetition of steps 1 to 8, coating the inner wall of the target material 1 with a layer of indium that meets the requirements of the next process. The operation process has two modes: manual and automatic.

[0026] The working principle of this utility model is as follows: 1. Open the heating chamber cover 32, place the pre-clamped target material 1 on the two rollers 331 inside the heating chamber 31, adjust the distance of the upper limit ring 339 of the rollers 331 to prevent the target material 1 from moving; lower the heating chamber cover 32, and seal the front sealing plate 351 and the rear sealing plate 352 of the heating chamber; start the servo reduction motor 332 to drive the rollers 331 to rotate, start the heating plate 311, and start the circulating fan to make the target material 1 rotate continuously inside the heating chamber 31 for uniform heating.

[0027] 2. During the heating process of target 1, the heater in the indium heating assembly 5 is simultaneously activated to heat the indium in the indium disk 51 to a molten state for later use. After the target 1 is heated to the process set temperature, the ultrasonic coating assembly 4 is activated to heat the coating head. The forward and backward moving module 44 and the up and down moving module 43 are controlled to apply indium liquid to the coating head. The front sealing plate 351 of the heating box is opened. The forward and backward moving module 44 and the up and down moving module 43 are controlled to move the coating brush head 47 to the inner hole of the target 1 and apply indium to the inner wall of the target 1. The above actions are repeated, and combined with the uniform rotation of the target 1, a uniform layer of indium is coated on the inner wall of the target 1.

[0028] 3. When the coating reaches a certain thickness, open the heating chamber back cover 352 and use a special measuring tool to check the coating thickness; when the thickness meets the process requirements, stop coating, remove the coating brush head 47, and turn off the ultrasonic coating assembly 4. Turn off the heating chamber 31.

[0029] IV. When the temperature drops to the process setting, turn off the hot air circulation fan 343 and roller 331, open the heating box cover 32, remove the target material 1, and the operation is complete.
