[0044] In the embodiment, the contact wheel 8 is a first external gear, according to actual needs, the matching member 9 can be a second external gear engaged with the first external gear, and the second external gear is fixedly arranged on the carrier 6.

[0048] The coating mechanism 3 comprises a first feeding unit 18. The first feeding unit 18 comprises a first bracket 19 which is detachably connected with the cabinet 1 and is used to carry a first target material 23, a first heating unit which is installed on the first bracket 19 and is used to heat and evaporate the first target material 23, a first cooling unit which is used to cool the first target material 23 carried by the first bracket 19, and a first magnet 21 which is arranged on the first bracket 19 and acts on the target material ions after evaporation of the first target material 23. The target material ions after evaporation of the first target material 23 enter the cabinet 1 to deposit on the workpieces carried by the first carrier 7 to form a coating.

[0049] In actual use, the first heating unit of the first feeding unit 18 heats the first target material 23, so that the target material ions formed by heating and evaporation of the first target material 23 are deposited on the workpieces carried by the first carrier 7 in the accommodating cavity 4 of the cabinet 1 to realize automatic coating treatment. The first target material 23 is cooled by the first cooling unit, so that the first target material 23 is prevented from being cracked due to high temperature. The target material ions formed after evaporation of the first target material 23 are selected by the Lorentz force in the magnetic field of the first magnet 21 to accurately deposit on the workpieces in the accommodating cavity 4 of the cabinet 1.

According to actual needs, the cooling fluid can be cooling water, cooling oil or cooling gas, and of course, the first cooling unit is provided with a refrigeration member for lowering the temperature of the cooling fluid.

[0052] In actual use, the cooling fluid delivered by the first cooling unit flows through the first cooling flow channel 24 and the target material recess 25, thereby taking away the heat of the first target material 23 carried by the second carrier 22, achieving the cooling treatment of the first target material 23, and avoiding the first target material 23 from being cracked due to excessively high temperature.

[0053] The first magnet 21 is annular, and according to actual needs, the first magnet 21 can be a circular ring or a rectangular ring, and the first magnet 21 is sleeved on the outer side of the second carrier 22. After the first heating unit heats and evaporates the first target material 23 carried by the second carrier 22 into target material ions, the magnetic field of the first magnet 21 acts on the target material ions, so that the target material ions move and deflect under the action of the Lorentz force, and of course, the impurities mixed in the target material ions and the target material ions themselves are subjected to different sizes of the Lorentz force, thereby realizing the automatic selection of the target material ions, so that the target material ions accurately and stably enter the accommodating cavity 4 of the case 1 to be deposited on the workpiece, thereby improving the yield of the coating of the workpiece.

[0054] The coating mechanism 3 comprises a second supply unit 26, the second supply unit 26 comprises a second bracket 27 detachably connected with the cabinet 1 and used for carrying a second target material 29, a second heating unit and a second magnet 28 installed on the second bracket 27, a second cooling unit used for cooling the second target material 29 carried by the second bracket 27, the second bracket 27 is provided with a tapered hole 31 used for containing the second target material 29 and communicating with the cabinet 1, the aperture of the tapered hole 31 near one end of the cabinet 1 is larger than the aperture of the tapered hole 31 away from one end of the cabinet 1, the second heating unit is used for heating and evaporating the second target material 29 carried by the second bracket 27, and the second magnet 28 acts on the target material ions after evaporation of the second target material 29; the first target material 23 is a strip-shaped body, and the second target material 29 is a plate-shaped body.

[0055] In actual use, the two supply units respectively heat and evaporate the target materials in different forms into target material ions into the accommodating cavity 4 of the cabinet 1, thereby improving the compatibility of the coating machine. Of course, in actual use, the coating machine can also use only one supply unit, and the other supply unit is in a shutdown state.

[0056] The second bracket 27 is detachably connected with a tapered member 32, the tapered hole 31 is arranged on the tapered member 32 and penetrates through the tapered member 32, the tapered member 32 is used for pressing and limiting the second target material 29 on the second bracket 27, and the second target material 29 covers the opening of the tapered hole 31 away from one end of the cabinet 1.

[0057] The second bracket 27 is provided with a second cooling flow channel 33, a cooling container groove 34 in communication with the second cooling flow channel 33 is formed between the second target material 29 and the second bracket 27, and the second cooling unit is used for driving the cooling fluid outside to flow through the second cooling flow channel 33 and the cooling container groove 34 to cool and lower the temperature of the second target material 29 carried by the second bracket 27. Through the arrangement of the cooling container groove 34, the actual contact area of the cooling fluid and the second target material 29 is increased, and the cooling effect of the cooling fluid on the second target material 29 is improved.
