[0026] The present application relates to a vacuum coating machine, which includes a workpiece rack mechanism, and the tool loaded on the workpiece rack mechanism is located in the coating chamber of the vacuum coating machine.

[0027] The other components and operations of the vacuum coating machine are already recorded in the related art for those of ordinary skill in the art, and will not be described in detail here. The following will introduce the structure of the workpiece rack mechanism.

[0028] Combined with Att Figure 1 to Att Figure 3 , the present application relates to a workpiece rack mechanism, which includes a carrier 1100 and at least one rod 1200. The rod 1200 is arranged on the carrier 1100, and the blade is sleeved on the outer sidewall of the rod 1200. It can be understood that the carrier 1100 and the rod 1200 are located in the coating chamber of the vacuum coating machine.

[0029] Combined with Att Figure 1, the stage 1100 is set as a frustum or a circular plate, and the stage 1100 is rotatable. Specifically, the workpiece holder mechanism includes a main transmission structure 2101 and a driver 2102. The upper end of the main transmission structure 2101 is fixedly connected to the bottom of the stage 1100, and the main transmission structure 2101 and the stage 1100 are arranged with the same central axis. The driver 2102 drives the stage 1100 to rotate through the main transmission structure 2101, and the stage 1100 rotates with its own central axis as the rotation axis. During the rotation of the stage 1100, the material rod 1200 moves around the central axis of the stage 1100, so as to realize the revolution of the material rod 1200 around the central axis of the stage 1100.

[0030] Further, in combination with the attached Figure 1 and the attached Figure 2 , the workpiece holder mechanism includes a base 1300. The driver 2102 is arranged on the base 1300, the main transmission structure is rotatably arranged on the base 1300, and the base 1300 can carry the driver 2102 and the main transmission structure 2101.

[0031] In combination with the attached Figure 3 , the workpiece holder mechanism includes a gear disk 2201. The gear disk 2201 drives the material rod 1200 to rotate through gears, so as to realize the rotation of the material rod 1200 with its own central axis as the rotation axis, that is, the material rod 1200 realizes self-rotation. It can be understood that the material rod 1200 revolves with the rotation of the stage 1100, and the material rod 1200 rotates on the stage 1100, so that the blades on the material rod 1200 can continuously adjust the orientation, improving the uniformity of the coating on the blade surface.

[0032] It should be noted that the gear disk 2201 is fixedly connected to the base 1300, so that the gear disk 2201 is fixed relative to the base 1300. Specifically, the gear disk 2201 is arranged on the upper side of the base 1300 through a column. In this case, when the stage 1100 rotates and the material rod 1200 revolves, the stationary gear disk 2201 drives the material rod 1200 to rotate through gears.

[0033] As an implementation manner, in combination with the attached Figure 2 , a first transmission gear 3101 is arranged at the lower end of the material rod 1200, and the gear disk 2201 drives the material rod 1200 to rotate in a gear meshing transmission manner.

[0034] Specifically, in combination with the attached Figure 3 , the gear disk 2201 has external teeth, and the external teeth of the gear disk 2201 mesh with the first transmission gear 3101 of the material rod 1200 to drive the material rod 1200 to rotate self.

[0035] Further, in combination with the attached Figure 3, the workpiece rack mechanism includes a second transmission gear 3102, the second transmission gear 3102 is disposed at the bottom of the stage 1100, the rotating shaft of the second transmission gear 3102 is fixedly connected to the stage 1100, the second transmission gear 3102 meshes with the gear disk 2201 and the first transmission gear 3101 respectively, and the gear disk 2201 drives the material rod 1200 to rotate through the second transmission gear 3102. Specifically, the external teeth of the gear disk 2201 are in meshing transmission with the first transmission gear 3101 of one of the material rods 1200 through the second transmission gear 3102.

[0036] In some examples, a plurality of material rods 1200 are provided, and the material rods 1200 are distributed in a circumferential direction around the central axis of the stage 1100. When the stage 1100 rotates relative to the gear disk 2201, the material rods 1200 on the stage 1100 are meshed with the second transmission gear 3102 one by one, so as to realize the self-rotation of each material rod 1200.

[0037] In some examples, in combination with the attached Figure 3 , the first transmission gears 3101 of two adjacent material rods 1200 are meshed, and the first transmission gears 3101 of each material rod 1200 can also be in meshing transmission with each other.

[0038] In some examples, at least one second transmission gear 3102 is provided, and each second transmission gear 3102 is meshed with the external teeth of the gear disk 2201.

[0039] Regarding the gear disk 2201, there are at least the following alternative examples.

[0040] In some alternative examples, the gear disk 2201 has internal teeth, the first transmission gears 3101 of each material rod 1200 are located within the circular area of the gear disk 2201, and the internal teeth of the gear disk 2201 are in meshing transmission with the first transmission gears 3101 of the material rods 1200 to drive the material rods 1200 to rotate self. Further, the internal teeth of the gear disk 2201 are in meshing transmission with the first transmission gears 3101 of the material rods 1200 through the second transmission gear 3102.

[0041] It should be noted that the fixed connection position of the main transmission structure 2101 and the stage 1100 is within the circular area of the gear disk 2201. In this case, the gear disk 2201 has external teeth. Or, the gear disk 2201 has internal teeth, and the fixed connection position of the main transmission structure 2101 and the stage 1100 is within the area of the circumference where the material rods 1200 are located. Or, the gear disk 2201 has internal teeth, the internal teeth of the gear disk 2201 are in meshing transmission with the first transmission gears 3101 of the material rods 1200 through the second transmission gear 3102, the fixed connection position of the main transmission structure 2101 and the stage 1100 is within the circular area of the gear disk 2201, and outside the area of the circumference where the material rods 1200 are located.

[0042] Of course, the design can also be replaced as follows: the fixed connection position between the main transmission structure 2101 and the stage 1100 is outside the circular area of the gear disk 2201. In this case, the gear disk 2201 has internal teeth. Alternatively, the gear disk 2201 has external teeth, and the fixed connection position between the main transmission structure 2101 and the stage 1100 is outside the area of the circumference where the material rod 1200 is located. Alternatively, the gear disk 2201 has external teeth, the external teeth of the gear disk 2201 drive the first transmission gear 3101 of the material rod 1200 through the second transmission gear 3102, the fixed connection position between the main transmission structure 2101 and the stage 1100 is outside the circular area of the gear disk 2201 and within the area of the circumference where the material rod 1200 is located.

[0043] As an implementation manner, in combination with the attached Figure 1 and the attached Figure 2 , the main transmission structure 2101 is rotatably arranged on the base 1300 through the magnetorheological fluid 2103, and the magnetorheological fluid 2103 can provide a good sealing effect between the main transmission structure 2101 and the base 1300. Specifically, the inner bushing of the magnetorheological fluid 2103 is sleeved on the outer side wall of the main transmission structure 2101 and fixedly connected to the main transmission structure 2101, and the outer housing of the magnetorheological fluid 2103 is fixedly connected to the base 1300.

[0044] Further, at least one sealing ring is arranged between the outer housing of the magnetorheological fluid 2103 and the base 1300, and at least one sealing ring is arranged between the inner bushing of the magnetorheological fluid 2103 and the outer side wall of the main transmission structure 2101.

[0045] In some examples, a bushing is sleeved on the outer side wall of the main transmission structure 2101, and the inner bushing of the magnetorheological fluid 2103 is sleeved on the outer side wall of the bushing. At least one sealing ring is arranged between the inner side wall of the bushing and the outer side wall of the main transmission structure 2101, and at least one sealing ring is arranged between the inner side wall of the inner bushing of the magnetorheological fluid 2103 and the outer side wall of the bushing.
