[0032] like Figure 1As shown, the automatic feeding mechanism includes a feeding trolley, which is used to feed the metal coil into the unwinding mechanism. When feeding, the metal coil is first placed on the feeding trolley by a forklift, the end of the feeding trolley rises, and the feeding trolley moves along the track toward the unwinding mechanism area, and the inner hole of the metal coil is inserted into the unwinding roller, and the metal coil is sleeved on the unwinding roller.

[0033] like Figure 1 As shown, the unwinding mechanism includes an unwinding roller, an unwinding support arm and an unwinding pressure roller. The unwinding support arm is rotatably installed below the unwinding roller, and the unwinding pressure roller is rotatably installed above the unwinding roller. The unwinding support arm is used to support the cantilever end of the unwinding roller, and the unwinding pressure roller is used to press the metal coil on the unwinding roller. When the metal coil is mounted on the unwinding roller, the unwinding support arm rotates upward to hold the cantilever end of the unwinding roller and support the cantilever end of the unwinding roller; the unwinding pressure roller rotates downward to press the metal coil on the unwinding roller to prevent the metal coil from loosening. At the same time, the unwinding pressure roller rotates as the coil diameter of the metal coil on the unwinding roller changes, and the unwinding pressure roller always keeps in close contact with the metal coil on the unwinding roller.

[0034] like Figure 1 As shown, the cutting mechanism includes a straightening machine, a first clamping machine, a first flattening machine, a plate head shear, an automatic welding machine, a second clamping machine, a second flattening machine, a scrap cart, and a first transition table which are arranged in sequence. The metal coil coming out of the unwinding mechanism passes through the straightening machine, the first clamping machine, the first flattening machine, the plate head shear, the automatic welding machine, the second clamping machine, the second flattening machine, and the scrap cart in sequence, and enters the cleaning mechanism through the first transition table.

The metal coil is then brought into contact with the material by the first flattening machine, and then the metal coil passes through the scrap car, and the cut-off head falls into the scrap car.

[0035] like Figure 1 As shown, the cleaning mechanism includes a degreasing machine, a cleaning machine, a drying machine and a second transition table which are arranged in sequence. The metal coil coming out of the cutting mechanism passes through the degreasing machine, the cleaning machine and the drying machine in sequence, and enters the vacuum coating mechanism through the second transition table. The metal coil enters the degreasing machine through the first transition table. The degreasing machine sprays chemical reagents on the surface of the metal coil to remove the grease on the surface of the metal coil. Then the metal coil enters the cleaning machine. The cleaning machine sprays deionized water on the surface of the metal coil and uses upper and lower brushes to scrub the surface of the metal coil to clean the surface of the metal coil. Then the metal coil enters the drying machine. The drying machine thoroughly dries the moisture on the surface of the metal coil. Then the metal coil is output through the second transition table and enters the vacuum coating mechanism.

The coating method can be suspended coating or water-cooled roller coating. A second baking system is arranged in the vacuum chamber after coating. The metal coil coming out of the cleaning mechanism passes through the first conveying system, the ion treatment system, the first baking system, the coating source, and the second baking system in sequence, and enters the protective film sticking mechanism through the second conveying system. The metal coil enters the first conveying system through the second transition table. The first conveying system conveys the metal coil into the pre-coating vacuum chamber. In the pre-coating vacuum chamber, the ion treatment system first performs ion cleaning on the surface of the metal coil through a linear ion source or ion bombardment. Then the first baking system bakes the surface of the metal coil to remove the gas on the surface of the metal coil. Then the metal coil enters the coating chamber. The coating source in the coating chamber performs vacuum coating on the surface of the metal coil. Then the metal coil enters the post-coating vacuum chamber. The second baking system in the post-coating vacuum chamber bakes the surface of the metal coil to improve the bonding force between the metal coil and the film layer.

The upper and lower rollers of the third clamping machine press the protective film and the metal coil, and press the protective film tightly against the surface of the metal coil, and clamp the metal coil into the tension station. The tension station generates a certain tension on the metal coil. Then the metal coil enters the tail shear, which cuts the welding point between the metal coil and the previous metal coil, so that the metal coil is wound up one by one, realizing the automatic continuous production of metal coils one by one.

[0038] like Figure 1 As shown, the winding mechanism includes a winding roller, a winding support arm and a winding pressure roller. The winding support arm is rotatably installed below the winding roller, and the winding pressure roller is rotatably installed above the winding roller. The winding support arm is used to support the cantilever end of the winding roller, and the winding pressure roller is used to closely contact the metal coil on the winding roller. The metal coil cut from the tail of the plate is wound on the winding roller, and the winding support arm rotates upward to hold the cantilever end of the winding roller and support the cantilever end of the winding roller; the winding pressure roller rotates downward to closely contact the metal coil on the winding roller to prevent the metal coil from loosening.
