The workpiece-carrying hub mainly includes an upper connecting plate, a lower connecting plate, and an intermediate support connected between the upper connecting plate and the lower connecting plate. The upper connecting plate and the lower connecting plate are provided with a detachable connecting mechanism, which is used to connect and install the workpiece-carrying member carrying the workpiece. The workpiece-carrying member generally has two forms, namely, a hanging rod and a hanging plate. For the hanging rod, the detachable connecting mechanism of the workpiece-carrying hub is generally arranged in a structural form that allows the hanging rod to be driven to rotate by a driving mechanism. At the same time, a transmission mechanism (for example, a gear mechanism) for connecting to a motor to drive the hanging rod to rotate is arranged on the upper connecting plate or the lower connecting plate, thereby meeting the need for the hanging rod to rotate with the workpiece for coating. For the hanging plate, the detachable connecting mechanism of the workpiece-carrying hub is generally arranged in such a way that after the hanging plate is connected and installed, the hanging plate and the workpiece thereon are fixed relative to the workpiece-carrying hub.

[0003] Existing workpiece bearing hubs are all specially customized according to production requirements. When the size, structure, arrangement quantity and diameter of the workpiece bearing parts arranged on the workpiece bearing hub are adjusted, a different workpiece bearing hub needs to be manufactured and replaced as a whole for each adjustment change, which has the disadvantages of poor versatility, high cost and inconvenience in use.

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Embodiment 1:

[0027] like Figures 1 to 4 As shown, the workpiece bearing hub for vacuum coating of this embodiment comprises an intermediate pillar 3, an upper connecting plate 1 connected to the upper end of the intermediate pillar 3, and a lower connecting plate 2 connected to the lower end of the intermediate pillar 3. A plurality of detachable connecting mechanisms 4 are respectively provided on the upper connecting plate 1 and the lower connecting plate 2. The upper connecting plate 1 and the lower connecting plate 2 both comprise a replaceable part 21 and a main body 22 connected to the intermediate pillar 3. The replaceable part 21 is detachably connected and installed on the main body 22. The detachable connecting mechanism 4 is provided on the replaceable part 21. The workpiece bearing hub for vacuum coating, the upper connecting plate 1 and the lower connecting plate 2 both comprise a replaceable part 21 and a main body 22 connected to the intermediate pillar 3. The replaceable part 21 is detachably connected and installed on the main body 22. For different installation requirements of the workpiece, the main structure composed of the intermediate pillar 3 and the main body 22 can be retained, and only the replaceable part 21 and the detachable connecting mechanism 4 that match and adapt to the workpiece can be replaced, which can save costs and has the advantages of good versatility, convenient use, and convenient transportation and storage.

[0028] In this embodiment, the replaceable part 21 is an annular plate, which has high overall structural strength, strong load-bearing capacity, and is easy to manufacture and store. When connected with the main body 22, it can form a stable and reliable overall structure, and it is convenient to set up multiple detachable connecting mechanisms 4 along the annular path to meet the requirements of evenly installing the workpiece around the workpiece-carrying hub.

[0029] In this embodiment, the replaceable component 21 is detachably connected and installed on the main body 22 through a fastener, which is low in cost and convenient for disassembly and replacement. The fastener is a bolt.

[0030] In this embodiment, a transmission mechanism is also provided on the replaceable part 21 of the upper connecting disk 1 or the lower connecting disk 2, and the transmission mechanism is used to transmit power to the detachable connecting mechanism 4 that needs to drive the hanging rod to rotate. The transmission mechanism is set on the replaceable part 21 of the upper connecting disk 1 or the lower connecting disk 2, and is directly connected to the detachable connecting mechanism 4 on the replaceable part 21 of the upper connecting disk 1 or the lower connecting disk 2 for transmission, which is convenient for assembly. In this embodiment, the transmission mechanism is specifically set on the replaceable part 21 of the lower connecting disk 2. In other embodiments, the transmission mechanism can also be set on the replaceable part 21 of the upper connecting disk 1. The above-mentioned transmission mechanism is a gear transmission mechanism.

[0031] In this embodiment, a plurality of connecting rods 5 are connected between the main body 22 of the upper connecting plate 1 and the lower connecting plate 2, and the plurality of connecting rods 5 are evenly spaced around the middle pillar 3. The overall structural stability, anti-deformation capability and load-bearing capacity of the workpiece bearing hub for vacuum coating can be improved. Preferably, the plurality of connecting rods 5 are evenly spaced around the middle pillar 3.

[0032] In this embodiment, one or more reinforcing connectors 6 are connected between the main body 22 of the upper connecting plate 1 and / or the lower connecting plate 2 and the middle pillar 3 to prevent the main body 22 from bending and deforming away from the middle pillar 3. It can avoid the main body 22 of the upper connecting plate 1 and the lower connecting plate 2 from bending and deforming due to gravity after the workpiece is installed, ensure the position accuracy of the workpiece, thereby providing stable reliability of the coating work and improving the coating quality. Specifically, in this embodiment, a reinforcing connector 6 is connected only between the main body 22 of the lower connecting plate 2 and the middle pillar 3, and the reinforcing connector 6 plays the role of pulling the main body 22 of the lower connecting plate 2 to prevent it from bending and deforming. In other embodiments, a reinforcing connector 6 can also be connected only or simultaneously between the main body 22 of the upper connecting plate 1 and the middle pillar 3, and the main body 22 of the upper connecting plate 1 is supported by the reinforcing connector 6 to prevent it from bending and deforming.

By adjusting the length of the reinforcing connector 6, the connection stress of the reinforcing connector 6 can be adjusted to ensure the anti-bending deformation effect, and the reinforcing connector 6 adopts an adjustable telescopic rod, which is convenient for assembly and debugging.

[0034] In this embodiment, the adjustable telescopic rod comprises a first rod 61 and a second rod 62, the first rod 61 and the second rod 62 are threadedly connected and the length of the adjustable telescopic rod can be adjusted by screwing, the end of the first rod 61 away from the second rod 62 is rotatably connected to a first hinge seat 63 hinged to one of the middle pillar 3 and the main body 22, and the end of the second rod 62 away from the first rod 61 is connected to a second hinge seat 64 hinged to the other of the middle pillar 3 and the main body 22. The adjustable telescopic rod has a simple structure and is easy to adjust, and the structure and assembly form of the adjustable telescopic rod can adjust the length at any time after installation, thereby ensuring the anti-bending deformation effect.

[0035] In this embodiment, the detachable connecting mechanism 4 on the upper connecting plate 1 and the lower connecting plate 2 is a mechanism that can connect and install the hanging rod (the hanging rod is labeled G1 in the figure) and drive the hanging rod to rotate. Specifically, the commonly used technology in the existing workpiece carrying hub for vacuum coating can be adopted, which will not be repeated here.

[0036] Embodiment 2:

[0037] like Figure 5 and Figure 6 As shown, the vacuum coating workpiece bearing hub of this embodiment is basically the same as that of the embodiment 1, and the main difference is that, in this embodiment, the detachable connection mechanism 4 on the upper connection plate 1 and the lower connection plate 2 is a mechanism capable of connecting and installing the hanging plate, and the transmission mechanism and the reinforcing connection member 6 are not provided in this embodiment.
