Detailed Implementation

[0040] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0041] Please see Figure 1 and Figure 2 This application provides an optical coating workpiece holder 100, including a central rod 10, a mounting plate positioning member 70, and a mounting plate 60. A top plate 20 is fixedly connected to one end of the central rod 10, and a bottom plate 30, opposite to the top plate 20, is fixedly connected to the other end of the central rod 10. The mounting plate positioning member 70 is respectively installed on the side of the top plate 20 and the bottom plate 30 away from the central rod 10, and a tapered portion 72 is provided at the other end of the mounting plate positioning member 70. The mounting plate 60 passes through the mounting plate positioning member 70 and is fixedly connected to the top plate 20 and the bottom plate 30 under the action of the tapered portion 72.

[0042] Specifically, the center rod 10 may include a first end 11 and a second end 13. The top plate 20 can be welded to the first end 11 of the center rod 10, and the bottom plate 30 can be welded to the second end 13 of the center rod 10, so that the top plate 20 and the bottom plate 30 can be more firmly connected to the center rod 10 as a single unit. Alternatively, the top plate 20 can be screwed to the first end 11 of the center rod 10, and the bottom plate 30 can also be screwed to the second end 13 of the center rod 10, facilitating the installation and removal of the top plate 20 and the bottom plate 30. The center rod 10 can be located at the center of the top plate 20 and the main plate, serving to support the top plate 20 and the bottom plate 30. The center rod 10 can be cylindrical or rectangular, without limitation.

[0043] The number of mounting plate positioning components 70 can be multiple. Multiple evenly distributed positioning posts 23 can be provided circumferentially on the side of the top plate 20 and bottom plate 30 away from the central rod 10. The positioning posts 23 on the top plate 20 can correspond one-to-one with the positioning posts 23 on the bottom plate 30. Multiple positioning posts 23 can be grouped in pairs. A mounting plate positioning component 70 can be positioned circumferentially on the bottom plate 30 or top plate 20 by a group of positioning posts 23. Multiple mounting plate positioning components 70 can be equally divided into two groups, one of which can be positioned by... Positioning post 23 is positioned on the top plate 20 in the circumferential direction and then detachably fixed to the top plate 20 by screwing. Another set of positioning parts can be positioned on the bottom plate 30 in the circumferential direction via positioning post 23 and then detachably fixed to the bottom plate 30 by screwing. This allows the hanging plate positioning part 70 installed on the top plate 20 to correspond with the hanging plate positioning part 70 installed on the bottom plate 30. This facilitates the hanging plate 60 to pass through the hanging plate positioning part 70 and be fixedly connected to the top plate 20 and the bottom plate 30 under the action of the tapered part 72, so that the hanging plate 60 can be hung on the optical coating workpiece holder 100.

[0044] It should be noted that the center rod 10, base plate 30, top plate 20, hanging plate 60, and hanging plate positioning component 70 can all be made of metal. That is, when the center rod 10, base plate 30, top plate 20, hanging plate 60, and hanging plate positioning component 70 are all made of metal, for example, they can be made of aluminum alloy, so as to reduce the overall weight of the optical coating workpiece holder 100 while ensuring the rigidity of the center rod 10, base plate 30, top plate 20, hanging plate 60, and hanging plate positioning component 70.

[0045] Since the mounting plate 60 can be set with different sizes according to different coating requirements, the mounting plate positioning member 70 of the embodiment of this application can be adjusted during installation according to the different sizes of the mounting plate 60. The position of the mounting plate positioning member 70 installed on the top plate 20 and the bottom plate 30 can be adjusted to change the distance between each mounting plate positioning member 70 in the mounting plate 60 or the bottom plate 30, so that the mounting plates 60 of different specifications can be hung on the optical coating workpiece frame 100 through the mounting plate positioning member 70, thereby improving the expandability and versatility of the optical coating workpiece frame 100.

[0046] The embodiments of this application do not impose specific limitations on the size of the mounting plate positioning component 70. That is, the size of the mounting plate positioning component 70 can be set according to the specifications of the mounting plate 60, and no specific limitations are imposed here.

[0047] Thus, when the optical coating workpiece holder 100 of this embodiment needs to install the hanging plate 60, the hanging plate 60 can be directly inserted into the hanging plate positioning member 70. The hanging plate 60 can slide automatically and be fixedly connected to the top plate 20 and the bottom plate 30 under the action of the tapered part 12. There is no need for technicians to tighten the two ends of the hanging plate 60 with bolts or screws and other fasteners to fix it directly to the top plate 20 and the bottom plate 30. This makes the installation and disassembly of the hanging plate 60 simple and convenient, and the installation efficiency is high.

[0048] Please combine Figure 1 , Figure 2 and Figure 3 In some embodiments, the mounting plate positioning member 70 includes a fixing part 71, a positioning part 73, and a fastener 75. The fixing part 71 is respectively installed on the side of the top plate 20 and the bottom plate 30 away from the center rod 10. The positioning part 73 is connected to the fixing part 71 and is located on the side 21 of the top plate and the side 31 of the bottom plate. The fastener 75 is connected to the positioning part 73, and a tapered part 72 is provided on the side of the fastener 75 away from the fixing part 71. The mounting plate 60 is fixedly connected to the top plate 20 and the bottom plate 30 under the action of the tapered part 72.

[0049] Specifically, the fixing part 71 may be provided with positioning holes corresponding to the positioning post 23. After the fixing part 71 is positioned in the circumferential direction of the top plate 20 and the bottom plate 30 by passing through the positioning holes, the fixing part 71 can be installed on the top plate 20 and the bottom plate 30 by screwing or welding. The positioning part 73 can be connected to the side of the fixing part 71 away from the center rod 10 by welding or screwing, and is located on the side 21 of the top plate and the side 31 of the bottom plate. At this time, the fastener 75 can be inserted into the positioning part. The mounting plate 60 is positioned on the top plate 20, allowing one end to be attached to the fastener 75 on the top plate 20 and the other end to be attached to the corresponding fastener 75 on the bottom plate 30. Under the action of the tapered part 72, the mounting plate 60 slides automatically and is fixedly connected to the top plate 20 and the bottom plate 30. This eliminates the need for technicians to tighten both ends of the mounting plate 60 with bolts or screws, making the installation and removal of the mounting plate 60 simple, convenient, and efficient.

[0050] It should be noted that the fastener 75 can be a bolt or pin with a tapered portion 72, etc., and there are no restrictions here. The taper of the tapered portion 72 only needs to be sufficient to allow the hanging plate to slide automatically and be fixedly connected to the top plate 20 and the bottom plate 30 under the action of the tapered portion 72 when it is inserted into the fastener 75. There are no restrictions on the taper of the tapered portion 72 here.

[0051] Please see Figure 3In some embodiments, the fixing part 71 has a groove 713 corresponding to the fastener 75 on the side of the top plate 21 and the bottom plate 31, and the fastener 75 passes through the positioning part 73 and is located in the groove 713.

[0052] Specifically, the fixing part 71 has a groove 713 corresponding to the fastener 75 on the side of the top plate 20 and the bottom plate 31. When the positioning part 73 is connected to the fixing part 71, it can cover the groove 713. One end of the fastener 75 can pass through the positioning part 73 and be located in the groove 713. At this time, the length of the end of the fastener 75 located in the groove 713 can be adjusted according to the different thicknesses of the hanging plate 60, so as to adjust the length of the other end of the fastener 75 located outside the groove 713, so that hanging plates 60 of different thicknesses can be hung on the hanging plate positioning part 70, thereby improving the expandability and versatility of the optical coating workpiece holder 100.

[0053] Please combine Figure 4 , Figure 5 , Figure 6 and Figure 7 In some embodiments, a through hole 61 is provided on the side of the mounting plate 60 away from the center rod 10, corresponding to the positioning part 73. A positioning groove 63, which gradually decreases in height direction H along the mounting plate 60, is provided on the side of the mounting plate 60 facing the center rod 10, corresponding to the positioning part 73. The through hole 61 communicates with the positioning groove 63. A fastener 75 passes through the positioning part 73 and is located in the groove 713. The mounting plate 60 is hooked onto the fastener 75 through the through hole 61 and the positioning groove 63.

[0054] That is, a through hole 61 (rectangular or elliptical) can be provided on the side of the hanging plate 60 away from the center rod 10, corresponding to the positioning part 73 (e.g., Figure 6 As shown), a gourd-shaped positioning groove 63, which gradually decreases in height H along the side of the hanging plate 60 facing the center rod 10 and corresponding to the positioning part 73, is provided (e.g., Figure 7 As shown), the through hole 61 and the positioning groove 63 can be connected so that when the mounting plate 60 needs to be hung on the optical coating workpiece holder 100, the positioning groove 63 and the through hole 61 can be sequentially inserted into the fastener 75. At this time, since the positioning groove 63 is a gourd-shaped positioning groove 63 that gradually decreases in height H along the mounting plate 60, and the tapered part 72 of the fastener 75 has a certain taper, the mounting plate 60 will automatically slide down along the fastener 75 under the action of gravity, so that the smaller upper part of the gourd-shaped positioning groove 63 is fixed in the tapered part 72 (e.g., Figure 4 and Figure 5 As shown in the diagram, the mounting plate 60 is securely fixed to the optical coating workpiece holder 100. It should be noted that... Figure 6 and Figure 7The gourd-shaped positioning groove 63 shown is only for illustration. The specific shape of the positioning groove 63 is only required to ensure that the fastener 75 can fix the hanging plate 60 after it slides down along the fastener 75 under the action of gravity. There are no restrictions here.

[0055] Please see Figure 3 In some embodiments, the fixing part 71 includes a first sub-part 715 and a second sub-part 717. The first sub-part 715 is respectively mounted on the side of the top plate 20 and the bottom plate 30 away from the center rod 10. The second sub-part 717 is mounted on the side 21 of the top plate and the side 31 of the bottom plate and is connected to the first sub-part 715. The first sub-part 715 and the second sub-part 717 are perpendicular to each other, and the positioning part 73 is connected to the second sub-part 717.

[0056] That is to say, such as Figure 3 As shown, the first sub-part 715 is integrally formed and connected to the second sub-part 717 in an L-shape perpendicular to each other, simplifying the production process. The first sub-part 715 can be installed on the side of the top plate 20 and the bottom plate 30 away from the center rod 10 by screwing or welding. The second sub-part 717 can be installed on the side 21 of the top plate and the side 31 of the bottom plate by screwing or welding. The positioning part 73 can be connected to the second sub-part 717 by screwing or welding, so that the positioning part 73 can be installed more closely on the top plate 20 and the bottom plate 30, while ensuring that the positioning part 73 can be stably connected to the side of the fixing part 71 away from the center rod 10, which facilitates the installation of the hanging plate 60 on the optical coating workpiece holder 100.

[0057] It should be noted that the first sub-part 715 and the second sub-part 717 of this application may not be perpendicular to each other. That is, the second sub-part 717 can be tilted at a certain angle when connected to the first sub-part 715, so that the positioning member is also tilted at a certain angle when connected to the first sub-part 715, thereby adjusting the angle at which the hanging plate 60 is hung on the hanging plate positioning member 70.

[0058] Please see Figure 8 In some embodiments, the optical coating workpiece holder 100 further includes a plurality of reinforcing members 40. The plurality of reinforcing members 40 are evenly distributed on the top plate 20 or the bottom plate 30 and connected to the central rod 10.

[0059] That is, in one embodiment, such as Figure 8 As shown, one end of each of the multiple reinforcing members 40 can be connected to the central rod 10 by welding or screwing, and the other end of each of the multiple reinforcing members 40 can be connected to the base plate 30 or the top plate 20 by welding or screwing. This allows the weight acting on the top plate 20 or the base plate 30 to be transferred to the central rod 10 through the multiple reinforcing members 40, thereby enhancing the weight that the central rod 10, the base plate 30, and the top plate 20 can withstand. This ensures that even when the optical coating workpiece holder 100 is fully loaded with hanging plates 60 (such as...), the weight can be increased. Figure 2 As shown in the figure, the base plate 30 or top plate 20 will not deform due to gravity, and the optical coating workpiece holder 100 is not easily damaged by excessive gravity, thus improving production efficiency.

[0060] It should be noted that the reinforcing members 40 can be made of metal. That is, when all reinforcing members 40 are made of metal, for example, they can be made of aluminum alloy, to reduce the overall weight of the optical coating workpiece holder 100 while ensuring the rigidity of the reinforcing members 40. The interior of the center rod 10 can be hollow or solid. When the interior of the center rod 10 is hollow, the weight of the center rod 10 can be reduced; when the interior of the center rod 10 is solid, the rigidity of the center rod 10 can be increased, so that the center rod 10 can bear more of the weight transmitted by the base plate 30 or the top plate 20 through the reinforcing members 40. There can be multiple reinforcing members 40, for example, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, etc., without limitation.

[0061] Thus, in this embodiment of the application, by connecting one end of the reinforcing member 40 to the central rod 10 and the other end of the reinforcing member 40 to the top plate 20 and / or the bottom plate 30 respectively, the reinforcing member 40 can support the central rod 10, the bottom plate 30 and the top plate 20. This allows the gravity acting on the bottom plate 30 and the top plate 20 to be transferred to the central rod 10 through the reinforcing member 40, thereby enhancing the gravity that the bottom plate 30 and the top plate 20 can withstand. This ensures that even if the optical coating workpiece holder 100 is fully loaded with hanging plates 60, the bottom plate 30 and the top plate 20 will not deform due to gravity. The optical coating workpiece holder 100 is less likely to be damaged due to excessive gravity, thus improving the strength, stability and production efficiency of the optical coating workpiece holder 100.

[0062] In addition, such as Figure 8 or Figure 9 As shown, the optical coating workpiece holder 100 of this application embodiment may further include multiple support rods 50. One end of the support rod 50 may be connected to the top plate 20, and the other end of the support rod 50 may be connected to the bottom plate 30. The multiple support rods 50 may be evenly distributed along the circumference of the top plate 20 and the bottom plate 30. In addition to the central rod 10 and the reinforcing member 40, the support rods 50 support the top plate 20 and the bottom plate 30. This allows the gravity acting on the top plate 20 and the bottom plate 30 to be transferred to the central rod 10 through the reinforcing member 40, while the support rods 50 support the top plate 20 and the bottom plate 30, thus sharing the weight borne by the top plate 20 and the bottom plate 30. This greatly enhances the weight that the bottom plate 30 and the top plate 20 can bear, so that even if the optical coating workpiece holder 100 is fully hung with hanging plates 60, the bottom plate 30 and the top plate 20 will not deform due to gravity. The optical coating workpiece holder 100 is not easily damaged by excessive gravity, thus improving production efficiency.

[0063] like Figure 10 As shown, a connecting rod 51 can be provided between two adjacent support rods 50. The connecting rod 51 can be connected to the support rod 50 by screwing or welding, so that the center rod 10, support rod 50, reinforcing member 40 and connecting rod 51 are connected into an integral frame. The top plate 20 and bottom plate 30 can be respectively set at both ends of the integral frame, which greatly improves the strength and stability of the optical coating workpiece holder 100.

[0064] It should be noted that both the support rod 50 and the connecting rod 51 can be made of metal. That is, when both the support rod 50 and the connecting rod 51 are made of metal, for example, they can be made of aluminum alloy, so as to reduce the overall weight of the optical coating workpiece holder 100 while ensuring the rigidity of the support rod 50 and the connecting rod 51.

[0065] Please see Figure 10 In some embodiments, the optical coating workpiece holder 100 includes a reinforcing member 40. The reinforcing member 40 includes a plurality of first reinforcing sub-members 42 and a plurality of second reinforcing sub-members 44. The plurality of first reinforcing sub-members 42 are evenly distributed on the top plate 20 and connected to the central rod 10. The plurality of second reinforcing sub-members 44 are evenly distributed on the bottom plate 30 and connected to the central rod 10.

[0066] Specifically, such as Figure 10 As shown, one end of each of the plurality of first reinforcing sub-components 42 can be connected to the center position of the central rod 10 in the height direction h by welding or screwing. The other end of each of the plurality of first reinforcing sub-components 42 can also be connected to the top plate 20 by welding or screwing to evenly distribute them on the top plate 20 to support the top plate 20. One end of each of the plurality of second reinforcing sub-components 44 can be connected to the center position of the central rod 10 in the height direction h by welding or screwing. The other end of each of the second reinforcing sub-components 44 can also be connected to the base plate 30 by welding or screwing to be evenly distributed on the base plate 30 to support the base plate 30. This allows the gravity acting on the top plate 20 and the base plate 30 to be evenly transmitted to the center rod 10 through the first reinforcing sub-component 42 and the second reinforcing sub-component 44, thereby further enhancing the gravity that the base plate 30 and the top plate 20 can withstand. This ensures that even if the optical coating workpiece holder 100 is fully hung with hanging plates 60, the base plate 30 and the top plate 20 will not deform due to gravity. The optical coating workpiece holder 100 is less likely to be damaged due to excessive gravity, thus improving production efficiency.

[0067] Please see Figure 11In some embodiments, the reinforcing member 40 includes a pull plate 41, a mounting base 43, and a tensioning block 45. The tensioning block 45 is fixedly mounted on the top plate 20 and / or the bottom plate 30, respectively. The mounting base 43 includes a seat body 431 and a spacing adjustment member 433. The seat body 431 is connected to the tensioning block 45 via the spacing adjustment member 433, which is capable of adjusting the distance between the seat body 431 and the tensioning block 45. One end of the pull plate 41 is connected to the center rod 10, and the other end of the pull plate 41 is connected to the seat body 431.

[0068] In other words, since the length of the reinforcing member 40 is fixed, but there are production accuracy issues during actual production, the stress on the reinforcing member 40 produced may be uneven. Therefore, this application can change the distance between the tension block 45 and the seat 431 by twisting the pitch adjustment component 433, thereby changing the position of the seat 431 on the top plate 20 or the bottom plate 30 to adapt to the installation position of the reinforcing member 40. This ensures that the reinforcing member 40 can more evenly transfer the gravity of the bottom plate 30 or the top plate 20 to the center rod 10, while reducing the assembly accuracy of the reinforcing member 40. It should be noted that the tension block 45 can refer to a metal block with screw holes, etc., and is not limited here. The pitch adjustment component 433 can be a bolt or screw, etc., and is not limited here.

[0069] In one embodiment, the number of reinforcing members 40 can be multiple. Tensioning blocks 45 can be evenly distributed on the side of the top plate 20 or bottom plate 30 facing the central rod 10 by welding and located in the circumferential direction of the top plate 20 or bottom plate 30. The seat body 431 can be detachably connected to the tensioning blocks 45 by the spacing adjustment member 433. One end of the pull plate 41 can be connected to the central rod 10 by welding or screwing, and the other end of the pull plate 41 can be connected to the seat body 431 by welding or screwing. This ensures that when the hanging plate 60 is hung on the bottom plate 30 and the top plate 20, the reinforcing members 40 can more evenly transfer the gravity of the bottom plate 30 or top plate 20 to the central rod 10, while reducing the assembly accuracy of the reinforcing members 40.

[0070] In another embodiment, the number of reinforcing members 40 can be multiple, and the multiple reinforcing members 40 can be equally divided into two groups. One group of tensioning blocks 45 can be evenly distributed on the side of the top plate 20 facing the central rod 10 by welding, and located in the circumferential direction of the top plate 20. The seat body 431 can be detachably connected to the tensioning blocks 45 located on the top plate 20 by a spacing adjustment member 433. One end of the pull plate 41 can be connected to the central rod 10 by welding or screwing, and the other end of the pull plate 41 can be connected to the seat body 431 by welding or screwing. The other group of tensioning blocks 45 can be evenly distributed by welding. The reinforcing members are evenly distributed on one side of the base plate 30 facing the center rod 10 and located in the circumferential direction of the base plate 30. The seat body 431 can be detachably connected to the tension block 45 located on the base plate 30 through the spacing adjustment member 433. One end of the pull plate 41 can be connected to the center rod 10 by welding or screwing, and the other end of the pull plate 41 can be connected to the seat body 431 by welding or screwing. When the hanging plate 60 is hung on the base plate 30 and the top plate 20, it can further ensure that the reinforcing member 40 can more evenly transfer the gravity of the base plate 30 or the top plate 20 to the center rod 10, while reducing the assembly accuracy of the reinforcing member 40.

[0071] Please combine Figure 1 and Figure 2 In some embodiments, the optical coating workpiece holder 100 further includes a spacer baffle assembly 80. One end of the spacer baffle assembly 80 is connected to the top plate 20, and the other end of the spacer baffle assembly 80 is connected to the bottom plate 30. The spacer baffle assembly 80 is located on one side of the hanging plate positioning member 70. When the hanging plate 60 is connected to the top plate 20 and the bottom plate 30 respectively through the hanging plate positioning member 70, the hanging plate 60 is partially located on the spacer baffle assembly 80.

[0072] Specifically, one end of the spacer baffle assembly 80 can be screwed to the top plate 20, and the other end can also be screwed to the bottom plate 30, located on one side of the mounting plate positioning member 70, to facilitate the installation and removal of the spacer baffle assembly 80. Alternatively, one end of the spacer baffle assembly 80 can be welded to the top plate 20, and the other end can also be welded to the bottom plate 30, located on one side of the mounting plate positioning member 70, so that the spacer baffle assembly 80 is securely installed on the top plate 20 and the bottom plate 30. When the mounting plate 60 is connected to the top plate 20 and the bottom plate 30 respectively via the mounting plate positioning member 70, the mounting plate 60 can be partially located on the spacer baffle assembly 80, thereby blocking the gaps between the mounting plates 60 and preventing sputtered particles from entering the optical coating workpiece holder 100.

[0073] In some embodiments, there are multiple mounting plates 60, which are spaced apart on the top plate 20 and the bottom plate 30. A spacer baffle assembly 80 is located between two adjacent mounting plates 60.

[0074] That is, there can be multiple hanging plates 60, which can be spaced apart on the top plate 20 and the bottom plate 30. There can also be multiple spacer baffle assemblies 80, which can be evenly distributed along the circumference of the top plate 20 and the bottom plate 30 between adjacent hanging plates 60. When multiple hanging plates 60 are connected to the top plate 20 and the bottom plate 30 respectively through the hanging plate positioning member 70, parts of two adjacent hanging plates 60 can be located on the spacer baffle assembly 80 between the two adjacent hanging plates 60. Thus, the spacer baffle assembly 80 can block the gap between the two adjacent hanging plates 60 and prevent sputtered particles from entering the optical coating workpiece holder 100.

[0075] It should be noted that the number of spacer baffle assemblies 80 can be related to the number of hanging plates 60 attached to the optical coating workpiece holder 100, and is not limited here. For example, if there are four hanging plates 60 attached to the optical coating workpiece holder 100, then there can also be four spacer baffle assemblies 80 evenly distributed around the top plate 20 and the bottom plate 30, so that the spacer baffle assemblies 80 can block the gaps between all the hanging plates 60 and prevent sputtered particles from entering the workpiece holder.

[0076] Please combine Figure 2 and Figure 12 In some embodiments, the partition baffle assembly 80 includes a partition portion 81 and connecting portions 83 respectively disposed at both ends of the partition portion 81. The partition portion 81 includes a first sub-plate portion 811 and a second sub-plate portion 813, which are connected at a predetermined angle to each other. The partition portion 81 is connected to the top plate 20 and the bottom plate 30 through the connecting portions 83.

[0077] Specifically, the partition portion 81 and the connecting portions 83 respectively provided at both ends of the partition portion 81 can be integrally formed to simplify the production process. When the first sub-plate portion 811 and the second sub-plate portion 813 are connected, the first sub-plate portion 811 and the second sub-plate portion 813 can be connected at a preset angle to make the cross section of the partition portion 81 triangular. This allows the partition portion 81 to be installed side by side with the hanging plate 60 and between two adjacent hanging plates 60 when the hanging plate 60 is installed on the optical coating workpiece holder 100, thus blocking the gap between the hanging plates 60 and preventing sputtered particles from entering the workpiece holder. The connecting portion 83 can be provided with a guide portion 85. When the spacer baffle assembly 80 is installed on the top plate 20 and the bottom plate 30, the connecting portions 83 provided at both ends of the partition portion 81 can be positioned on the top plate 20 and the bottom plate 30 by the guide portion 85, and the partition portion 81 can be firmly connected to the top plate 20 and the bottom plate 30 by screwing through the spacing adjustment member 433. It should be noted that the preset angle can be, for example, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees or 50 degrees, and there are no restrictions here.

[0078] Please see Figure 13 In some embodiments, the top plate 20 and / or the bottom plate 30 are provided with origin sensing blocks 25. Since the optical coating workpiece holder 100 needs to be rotated for coating in actual application, and the mounting plate 60 is installed by a robot with a fixed working position, this application can use the origin sensing blocks 25 in conjunction with sensors to determine how much the optical coating workpiece holder 100 has rotated, so that the robot can easily position the angle of the optical coating workpiece holder 100 and install the mounting plate 60 on the optical coating workpiece holder 100.

[0079] Please combine Figure 9 , Figure 14 , Figure 15 and Figure 16 In some embodiments, the first end 11 and the second end 13 of the center rod 10 both include an outer ring portion 15 and an inner ring portion 17 located within the outer ring portion 15. A first connecting flange 151 is provided on the outer ring portion 15, and a second connecting flange 171 is provided on the inner ring portion 17. When the optical coating workpiece holder 100 needs to be connected to the drive assembly (not shown in the figure), the optical coating workpiece holder 100 can be fixedly connected to the drive assembly through the first connecting flange 151 and the second connecting flange 171, so that the drive assembly can drive the optical coating workpiece holder 100 to rotate.

[0080] Please combine Figure 2 and Figure 16In some embodiments, the center rod 10 has a hollow structure, and a positioning guide post 19 is provided inside the hollow structure. When the optical coating workpiece holder 100 needs to be connected to the drive assembly (not shown in the figure), the drive assembly can be aligned with the center position of the optical coating workpiece holder 100 through the positioning guide post 19, so that after the optical coating workpiece holder 100 is connected to the drive assembly, the drive assembly can drive the optical coating workpiece holder 100 to rotate by friction with the two conical ends of the positioning guide post 19.
