[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] This embodiment discloses a workpiece support device for a vacuum coating machine, referring to... Figures 1-4 As shown, the system includes a central column 1, an upper support plate 2, a lower support plate 3, a support base plate 5, and several mold support rods 4. The upper support plate 2 is fixed to the upper end of the central column 1, and the lower support plate 3 is fixed to the lower end of the central column 1. Both the upper support plate 2 and the lower support plate 3 are disc-shaped structures, with the central column 1 located at the center.

[0031] The supporting base plate 5 is located below the lower supporting plate 3 and is also supported by the central column 1. The upper supporting plate 2, the lower supporting plate 3, and the supporting base plate 5 form a three-layer structure.

[0032] The upper support plate 2 has several upper limit holes 21, and the lower support plate 3 has several lower limit holes 31, with the lower limit holes 31 corresponding one-to-one with the upper limit holes 21.

[0033] Reference Figure 4 As shown, an upper limit post 411 is fixedly connected to the upper end 41 of the mold frame support rod 4, and a lower limit post 421 is fixedly connected to the lower end 42 of the mold frame support rod 4. The mold frame support rod 4 is installed between the upper support plate 2 and the lower support plate 3. Several workpiece support molds 43 are fixedly installed along the length of the mold frame support rod 4. The workpieces to be vacuum coated can be processed through the workpiece support molds 43. The shape and structure of the workpiece support molds 43 are selected according to the specific workpiece to be processed, as long as they can support the workpiece.

[0034] During installation, the mold frame support rod 4 is in a vertical position. First, the upper limit post 411 at the upper end of the mold frame support rod 4 is inserted into the upper limit hole 21. Then, the lower limit post 421 at the lower end of the mold frame support rod 4 is inserted into the lower limit hole 31. Then, the lower end of the lower limit post 421 is pressed and supported by the support base plate 5, which can achieve stable support for the mold frame support rod 4.

[0035] The upper limit post 411 and the upper limit hole 21 can rotate relative to each other axially, and the lower limit post 421 and the lower limit hole 31 can rotate relative to each other axially. The upper limit hole 21 is a circular hole, and the upper limit post 411 is a cylindrical rod with a diameter smaller than that of the upper limit hole 21. After the upper limit post 411 is inserted into the upper limit hole 21, it can rotate relative to each other and can make a small yaw adjustment within the upper limit hole 21 to accommodate the disassembly and assembly of the mold support rod 4.

[0036] Reference Figure 2As shown, the inner circumference of the lower limiting hole 31 is formed with several limiting grooves 311, which are arranged in a ring array. For example, the cross-sectional profile of the lower limiting hole 31 is petal-shaped. Correspondingly, the cross-section of the lower limiting post 421 is adapted to the lower limiting hole 31, and part of the lower limiting hole 31 is embedded in the limiting groove 311 to achieve rotational limiting, thereby ensuring the stability of the mold support rod 4 after installation and avoiding rotational misalignment.

[0037] When the mold frame support rod 4 is installed, the angle of the lower limit post 421 when it is inserted into the lower limit hole 31 can be adjusted, thereby adjusting the orientation of the mold frame support rod 4 and the workpiece installed on the mold frame support rod 4, so that the workpiece can be oriented in different ways to adapt to the hanging of the workpiece to be processed in the entire workpiece support device.

[0038] Reference Figure 1 , 3 As shown, several sets of lower limit holes 31 are provided, each set of lower limit holes 31 being distributed in a ring around the central column 1, with each set of lower limit holes 31 arranged in a concentric circle structure. In this embodiment, four sets of lower limit holes 31 are provided, arranged in a concentric circle structure around the central column 1, with the outermost set of lower limit holes 31 having the most holes, and the innermost set having the fewest holes. When installing the mold frame support rod 4, the operator can select the installation hole position according to the different sizes of the workpiece.

[0039] Example 2

[0040] This embodiment discloses a workpiece support device for a vacuum coating machine, which is based on Embodiment 1 and further refers to... Figure 5 , Figure 6 Please provide a detailed explanation.

[0041] Reference Figure 5 As shown, an extension sleeve 7 is installed with an internal thread in the upper limit hole 21. Specifically, the extension sleeve 7 has an external thread machined on its outer circumference, and the upper limit hole 21 has an internal thread machined on its inner circumference. After the extension sleeve 7 extends into the upper limit hole 21, a threaded connection structure can be formed. The extension sleeve 7 can be adjusted up and down relative to the upper support plate 2 by rotating the extension sleeve 7 with the thread.

[0042] When the mold frame support rod 4 is installed, the upper limit post 411 is inserted into the extension sleeve 7, which can accommodate and limit the upper end of the mold frame support rod 4 through the extension sleeve 7, so that the mold frame support rod 4 can be kept vertically installed and supported.

[0043] During the reagent coating production process, the length of the mold support rod 4 used in the workshop may vary slightly. Differences in batches, wear, and torsional deformation can all lead to dimensional variations. By adjusting the height of the extension sleeve 7, the position can accommodate mold support rods 4 of varying lengths. After the mold support rod 4 is installed, if the upper limit post 411 at the upper end of the mold support rod 4 is inserted too small into the upper limit hole 21 (which is also equivalent to the inner hole of the extension sleeve 7), the extension sleeve 7 can be adjusted downwards via the thread, allowing it to fit a longer length around the upper limit post 411. This provides a stable limiting effect, preventing the mold support rod 4 from easily falling off when subjected to impact or vibration.

[0044] Additionally, refer to Figure 6 As shown, a support gap 6 is formed between the support base plate 5 and the lower support plate 3, and the lower side of the lower limit post 421 can extend into the support gap 6 through the lower limit hole 31.

[0045] In this embodiment, the distance between the support base plate 5 and the lower support plate 3 can be adjusted, that is, the width of the support gap 6 can be adjusted.

[0046] A connecting sleeve 51 is fixedly connected to the center of the supporting base plate 5, and a lower extension end 11 is formed on the lower side of the lower support plate 3 at the lower end of the central column 1. An internal thread is machined on the inner circumference of the connecting sleeve 51, and a matching external thread is machined on the outer circumference of the lower extension end 11. The connecting sleeve 51 is fitted onto the outer circumference of the lower extension end 11 and they are threadedly connected to each other.

[0047] By rotating the support base plate 5, the connecting sleeve 51 can be driven to rotate, and the connecting sleeve 51 and the lower extension end 11 of the central column 1 can generate threaded rotation adjustment, thereby adjusting the upper position of the connecting sleeve 51, realizing threaded adjustment, and adjusting the width of the support gap 6.

[0048] In addition, a lower stop 111 is fixedly connected to the lower side of the lower extension end 11, which can limit the formation of the lower side of the connecting sleeve 51 and prevent the connecting sleeve 51 from falling off due to excessive descent.

[0049] By adjusting the height of the support base plate 5, the lower support position of the mold frame support rod 4 can be raised as a whole, allowing the mold frame support rod 4 to adapt to the length of different models of mold frame support rods 4. Generally, the mold frame support rod 4 is mainly used during the initial equipment commissioning stage. Subsequently, it can be adjusted in conjunction with the extension sleeve 7, depending on the actual situation.

[0050] This embodiment also discloses a vacuum coating machine, including a vacuum coating machine body, in which the above-mentioned workpiece support device is installed to support the workpiece to be processed.

[0051] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
