Description

Technical Field

[0001] This utility model relates to the field of PVD mounting equipment, specifically a PVD shielding mounting plate. Background Technology

[0002] In physical vapor deposition (PVD) coating processes, the PVD masking rack is an indispensable key component. The PVD masking rack is a device used to fix and mask the workpieces to be coated in the physical vapor deposition coating process. Multiple workpieces to be coated are fixed on the mounting plate and mounting ring by the mounting assembly, ensuring that the workpieces maintain a stable position during the PVD coating process. This can increase the number of workpieces coated at one time and improve production efficiency.

[0003] Traditional mounting trays are typically designed with specific raised or recessed structures to mask products during coating. However, these rigid structures often fail to fully adhere to the product surface when partially masking products of different shapes, especially when masking special or irregularly shaped products. This results in unsatisfactory masking and consequently reduces the coating quality of the finished product.

[0004] Therefore, we provide a PVD masking mounting plate. Utility Model Content

[0005] The main purpose of this utility model is to provide a PVD masking fixture that can effectively solve the problem mentioned in the background art where the masking effect is not ideal when masking products with special shapes or irregular shapes, thereby reducing the coating quality of the finished product.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A PVD masking mounting tray includes a fixed tray. Multiple telescopic rods are equidistantly fitted and movably mounted on the top of the fixed tray, and these telescopic rods are nested sequentially. Each of the multiple telescopic rods has equidistantly spaced insertion holes for mounting the device. Multiple masking rods and mounting rods are provided on the outer sides of each telescopic rod. One side of each masking rod and mounting rod is fixedly connected to an insertion rod for mounting, and the insertion rod is movably connected to the insertion hole. A spring rod is fitted and mounted below each masking rod. A spring element is fixedly connected to the upper side of each spring rod, and the other side of the spring element is fixedly connected to the masking rod. A masking sticker for partially masking the coated product is fixedly mounted below each spring rod.

[0008] In the above scheme, preferably, the masking stickers are all made of high-temperature resistant flexible materials, and the masking stickers and the coating product are coated with an adhesive layer to improve the adhesion.

[0009] In the above scheme, preferably, each side of the mounting rod is provided with a recessed movable groove, and the two ends of the inner side of the movable groove are symmetrically fitted with sliders.

[0010] In the above scheme, preferably, a spring component is fixedly connected between one side of the slider and the movable groove, and a mounting rod for mounting the coating product is fixedly installed at one end of the slider.

[0011] In the above scheme, preferably, a rotating column is vertically fixed in the middle of the fixed plate, and a counterweight plate for providing downward pressure is movably installed above the rotating column, and the telescopic rods are all movably connected to the upper counterweight plate.

[0012] In the above scheme, preferably, both the upper and lower ends of the rotating column are fixedly connected to limiting blocks for limiting its installation on the coating table of the coating equipment, and a transmission gear is fixedly installed below the rotating column, and the transmission gear is connected to the power mechanism on the coating table.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This type of PVD masking mounting tray features a structure with a telescopic rod, a masking rod, and a mounting rod. The masking rod and mounting rod can be fixed by inserting the insert rod into the socket on the telescopic rod, and their horizontal positions can be adjusted by selecting different sockets. When masking a coated product is required, the insert rod with the masking rod is inserted into the appropriate socket, releasing the spring rod's compression space. The spring force pushes the spring rod, causing the masking sticker to adhere to the product surface. By inserting it into different sockets, the coated product can be partially masked at multiple locations, thus achieving multi-angle masking and improving the applicability of the masking.

[0015] This type of PVD masking rack features a structure incorporating a slider, a spring element, and a mounting rod. When mounting a product, the product is inserted into the mounting rod. The spring element's tension or push force causes the slider to move the mounting rod, either expanding or inwardly clamping the product. This adapts to the mounting needs of different products and ensures the product is securely fixed during the coating process. A counterweight plate is installed above the rotating column, applying pressure to the telescopic rod to ensure it fits tightly into the insertion hole, enhancing the stability of the telescopic rod during use. The rotating column is mounted on the coating stage via limit blocks at both ends. The lower transmission gear is connected to a power mechanism, which drives the transmission gear to rotate, causing the entire rack to rotate. This ensures the coated product receives the coating material evenly, effectively improving the uniformity and quality of the coating. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1-4 As shown, in this embodiment, a PVD masking hanger includes a fixed plate 1. A telescopic rod 3 is equidistantly fitted and movably mounted on the upper part of the fixed plate 1. Multiple telescopic rods 3 are nested sequentially. Each telescopic rod 3 has equidistantly spaced insertion holes 301 for hanger installation. Multiple masking rods 4 and hanging rods 5 are provided on the outer side of each telescopic rod 3. One side of each masking rod 4 and hanging rod 5 is fixedly connected to an insertion rod 8 for hanging, and the insertion rod 8 is movably connected to the insertion hole 301. A spring rod 401 is fitted and mounted below each masking rod 4. A spring element 403 is fixedly connected to the upper side of each spring rod 401, and the other side of the spring element 403 is fixedly connected to the masking rod 4. A masking sticker 402 for masking parts of the coated product is fixedly mounted below the spring rod 401.

[0024] Specifically, with this setup, the telescopic rods 3 are installed and used via the fixed plate 1. Since the telescopic rods 3 are multiple and extendable, when the mounting range needs to be adjusted according to the size of the coated product, the height of the counterweight plate 6 on the rotating column 2 is adjusted, thereby driving the multiple telescopic rods 3 that are movably connected to it to extend and retract. After adjusting to the appropriate length, the insert rod 8 is inserted into the overlapping insertion holes 301 of each telescopic rod 3, thus maintaining the stability between each telescopic rod 3. When it is necessary to mask the coated product, the insert rod 8 with the masking rod 4 is inserted into the insertion hole 301, and the spring rod 401 is manually released. The compression space in the shielding rod 4 causes the spring 403 to push out the spring rod 401, and the shielding sticker 402 on the spring rod 401 adheres to the surface of the coated product to achieve partial shielding. When it is necessary to shield the top of the coated product, the shielding rod 4 is placed above the hanging rod 5. If it is necessary to shield the bottom of the coated product, the shielding rod 4 is placed below the hanging rod 5. If it is necessary to shield the coated product from multiple angles, the shielding rod 4 is placed at the upper and lower ends of the hanging rod 5, and the insertion rod 8 with the shielding rod 4 is inserted into the insertion hole 301 by adjusting the orientation of the telescopic rod 3 on the side to achieve multi-angle shielding.

[0025] like Figures 1-4 As shown, in this embodiment, the masking stickers 402 are all made of high-temperature resistant flexible material, and the masking stickers 402 and the coating product are coated with an adhesive layer to improve the adhesion. One side of the mounting rod 5 is provided with a recessed movable groove 501. The two ends of the inner side of the movable groove 501 are symmetrically fitted with sliders 503. One side of the slider 503 and the movable groove 501 are fixedly connected with a spring element 504. One end of the slider 503 is fixedly installed with a mounting rod 502 for mounting the coating product.

[0026] Specifically, with this setup, since the masking sticker 402 is made of a high-temperature resistant flexible material, when the coated product is evaporated and coated, the masking sticker 402 and its adhesive layer can tightly adhere to the coated product, preventing it from being damaged by heat deformation during evaporation coating. Secondly, by inserting the coated product into the two mounting rods 502, the pulling force of the second spring 504 pulls the slider 503 to expand, thereby causing the mounting rods 502 on the slider 503 to expand and clamp the coated product. When it is necessary to clamp the coated product between the two mounting rods 502, the second spring 504 with a pushing force is selected. Through the pushing force of the second spring 504, the slider 503 moves inward, thereby causing the mounting rods 502 to tightly clamp the coated product, thus clamping the coated product inward for use.

[0027] like Figures 1-4As shown, in this embodiment, a rotating column 2 is vertically fixedly installed in the middle of the fixed disk 1. A counterweight disk 6 for providing downward pressure is movably installed above the rotating column 2, and the telescopic rods 3 are all movably connected to the counterweight disk 6 above. Limiting blocks 7 for limiting the rotating column 2 to be installed on the coating table of the coating equipment are fixedly connected to both the upper and lower ends of the rotating column 2. A transmission gear 201 is fixedly installed below the rotating column 2, and the transmission gear 201 is connected to the power mechanism on the coating table.

[0028] Specifically, with this setup, during use, the counterweight plate 6 applies pressure above the telescopic rod 3. After the insertion rod 8 is inserted into the insertion hole 301, the pressure from the counterweight plate 6 makes the insertion rod 8 tightly fit into the insertion hole 301. At the same time, the insertion rod 8 is inserted into the insertion holes 301 of multiple telescopic rods 3, thereby fixing each telescopic rod 3 to each other through the insertion rod 8, ensuring the stability of each telescopic rod 3 during use. The limiting blocks 7 at the upper and lower ends of the rotating column 2 limit its installation on the coating table of the coating equipment. The transmission gear 201 below the rotating column 2 is connected to the power mechanism on the coating table, thereby causing the power mechanism to drive the transmission gear 201 to rotate, which in turn drives the fixed plate 1 to rotate, so that the coated product receives the coating material evenly during the coating process, improving the uniformity and quality of the coating.

[0029] It should be noted that when using this utility model as a PVD masking hanger, the counterweight plate 6, which applies gravity above the telescopic rod 3, ensures that the rod 8 is tightly fitted into the insertion hole 301 after the rod 8 is inserted. Furthermore, multiple telescopic rods 3 are mutually fixed by the rods 8 to enhance stability during use. The upper and lower limit blocks 7 of the rotating column 2 are mounted on the coating table of the coating equipment. The transmission gear 201 below it is connected to the power mechanism of the coating table, thereby driving the transmission gear 201 to rotate and causing the entire device to rotate. When the hanging range needs to be adjusted according to the size of the coated product, the height of the counterweight plate 6 on the rotating column 2 is adjusted to extend or retract the telescopic rod 3. After adjusting to the appropriate length, the rod 8 is inserted into the overlapping insertion hole 301 to maintain the telescopic rod. The stability between 3 is achieved when partial masking of the coated product is required. Insert the plug 8 with the masking rod 4 into the plug hole 301, manually release the compression space in the spring rod 401, and let the spring element 1 403 push the spring rod 401 so that the masking sticker 402 is tightly attached to the surface of the coated product. During the evaporation coating process, the masking sticker 402 and its adhesive layer can tightly adhere to the coated product to prevent heat deformation. In addition, by inserting the coated product into the two mounting plugs 502 and using the pulling force of the spring element 2 504 to expand the slider 503, the mounting plugs 502 expand and clamp the coated product. When it is necessary to clamp the coated product between the two mounting plugs 502, select the spring element 2 504 with the pushing force, and use its pushing force to move the slider 503 inward to achieve tight clamping of the coated product.
