Detailed Implementation
[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.
[0015] The embodiments of this utility model relate to a vacuum furnace body for double-sided coating of wide-format products, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes: In this embodiment, a furnace structure 11 is provided on the vacuum furnace body for double-sided coating of wide-format products 9. The furnace structure 11 provides a closed environment for double-sided coating of wide-format products 9, protecting internal components from external interference.
[0016] A perforated structure 12 is provided on the furnace body structure 11. The perforated structure 12 is used to install the inner target 7 and the outer target 8.
[0017] An inner target 7 is installed on the furnace structure 11. The inner target 7 provides the coating material for the inner surface of the wide-format product 9. During magnetron sputtering, the inner target material is bombarded by high-energy particles, and target atoms or molecules are sputtered out and deposited on the inner surface of the wide-format product 9, forming a uniform film layer, thereby giving the inner surface of the product specific properties. The inner target 7 and the outer target 8 work together to enable simultaneous coating on both sides of the wide-format product 9, improving production efficiency and ensuring the quality of the double-sided coating.
[0018] An outer target 8 is set on the furnace body structure 11. The outer target 8 is used to coat the outer surface of the wide-plate product 9. The particles released by the outer target during the sputtering process are deposited on the outer surface of the product to form the required film layer, thereby improving the performance and appearance of the outer surface of the wide-plate product 9.
[0019] A wide plate product 9 is placed inside the furnace structure 11. The wide plate product 9 is between the inner target 7 and the outer target 8. When the wide plate product 9 is coated on both sides, the inner target 7 and the outer target 8 are opened at the same time. The wide plate product 9 only needs to revolve. The wide plate product 9 is a product that needs to be coated. It is coated on both sides in the vacuum furnace used for double-sided coating of the wide plate product, and a film layer is formed on its surface.
[0020] In this embodiment, an inner target 7 is provided on the furnace structure 11; an outer target 8 is provided on the furnace structure 11; a wide product 9 is placed inside the furnace structure 11; the wide product 9 is between the inner target 7 and the outer target 8. When the wide product 9 is coated on both sides, the inner target 7 and the outer target 8 are opened simultaneously, and the wide product 9 only needs to revolve. It has the advantages of very small change in target-substrate distance, good film uniformity, high coating efficiency, and large furnace capacity. It solves the technical problem in the prior art that the target of the coating cavity is generally installed on the outside of the furnace body. If the wide product is to be coated on both sides, the fixture needs to revolve and rotate on one side. However, because the product is wide, the target-substrate distance changes greatly during the rotation, resulting in large differences in film uniformity, low coating efficiency, and small furnace capacity.
[0021] To achieve the above-mentioned technical effects, such as Figure 1 and Figure 2 As shown, the furnace body structure 11 includes: A furnace body 3 is installed on a vacuum furnace body 3 used for double-sided coating of wide-format products. The furnace body 3 provides a closed environment for double-sided coating of wide-format products 9, protecting internal components from external interference.
[0022] A top cover 13 is fixed above the furnace body 3. The top cover 13, the furnace body 3, and the bottom plate 10 together form a completely enclosed space to prevent outside air from entering the furnace, ensuring that the required vacuum degree is maintained during the coating process and guaranteeing the quality of the coating. The top cover 13 also provides a mounting position for the top components. Moreover, during the operation of the vacuum furnace, a negative pressure is formed inside the furnace, and the top cover 13 withstands a certain amount of external atmospheric pressure.
[0023] A base plate 10 is fixedly connected to the bottom of the furnace body 3. The base plate 10 is the bottom support structure of the furnace body 3, which bears the weight of the entire furnace body 3 and the wide plate product 9 placed inside it. The base plate 10 provides an installation base for some bottom components inside the furnace body.
[0024] Furnace door 1 is movably connected to one side of furnace body 3. Furnace door 1 is the passage for the wide product 9 to enter and exit. Before the coating operation, furnace door 1 is opened and the wide product 9 is placed in the designated position inside the furnace. After the coating is completed, furnace door 1 is opened again and the product is taken out. When furnace door 1 is closed, it forms a sealed space with furnace body 3 to maintain a vacuum environment inside the furnace.
[0025] To achieve the above-mentioned technical effects, such as Figure 1 and Figure 2 As shown, the hole structure 12 includes: Several outer target mounting holes 4 are made on the upper cover 13, and the several outer target mounting holes 4 are used to connect the outer target 8.
[0026] Several inner target mounting holes 5 are made on the upper cover 13, and the several inner target mounting holes 5 are used to install the inner target 7.
[0027] To achieve the above-mentioned technical effects, such as Figure 1 As shown, the inner target 7 passes through the upper cover 13 of the furnace body structure 11 from top to bottom, and one end of the inner target 7 is fixedly connected to the inner target mounting hole 5 of the hole structure 12; the outer target 8 passes through the upper cover 13 of the furnace body structure 11 from top to bottom, and one end of the outer target 8 is fixedly connected to the outer target mounting hole 4 of the hole structure 12.
[0028] To achieve the above-mentioned technical effects, such as Figure 1 , Figure 2 and Figure 4 As shown, the furnace door 1 and the furnace body 3 are movably connected by several door hinges 2. The several door hinges 2 are used to connect the furnace door 1 and the furnace body 3, so that the furnace door 1 can rotate around the axis of the several door hinges 2, thereby opening and closing the furnace door 1.
[0029] To achieve the above-mentioned technical effects, such as Figure 1 and Figure 2 As shown, an air extraction port 6 is fixedly connected to the other side of the furnace body 3. The air extraction port 6 is connected to the inside of the furnace body 3. Before coating, the air extraction port 6 is connected to a vacuum pump to extract the air inside the furnace, creating a vacuum environment for the double-sided coating of the wide plate product 9 and ensuring the quality of the coating.
[0030] To achieve the above-mentioned technical effects, such as Figure 1 and Figure 2 As shown, a cooling water inlet 14 is provided on the upper cover 13; a cooling water outlet 15 is provided on the upper cover 13. The cooling water inlet 14 is used to connect to the source equipment that provides low-temperature cooling water, and the cooling water outlet 15 is used to connect to pipes or other equipment.
