Description

Technical Field

[0001] This utility model belongs to the field of vacuum coating technology, specifically relating to a carrier for granular vacuum coating agents. Background Technology

[0002] In the field of coating, the functional components in PVD (vacuum deposition) coating particles are mostly high-molecular liquids, so steel wool cakes or sintered inorganic materials are often used as adsorption carriers. With the upgrading of functional materials and manufacturing processes in recent years, some solid powders can also be evaporated and coated using PVD processes to form functional coatings with specific applications. Solid powders differ from liquid materials; using traditional manufacturing processes, they are prone to splashing and difficult to control the evaporation rate to form a uniform and dense coating. Therefore, it is necessary to provide a carrier for granular vacuum coating agents to solve the technical problems of easy splashing and difficulty in controlling the evaporation rate. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a carrier for granular vacuum coating agents, thereby solving the technical problems of easy splashing and spillage of agents and difficulty in controlling the evaporation rate when using carriers to load granular agents for vapor deposition.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a carrier for a granular vacuum coating agent, comprising a heat-conducting shell with an open top, wherein a bottom layer of steel wool is disposed inside the shell, an upper layer of steel wool is disposed on top of the bottom layer of steel wool, and a stainless steel mesh is disposed on top of the upper layer of steel wool. The bottom layer of steel wool is tightly embedded in the bottom of the shell, and the density of the bottom layer of steel wool is higher than that of the upper layer of steel wool. The density of the upper layer of steel wool is adjusted according to the evaporation rate of the agent. The four sides of the upper layer of steel wool are tightly attached to the inner walls of the shell. A layer of carbon fiber cloth is attached to the bottom surface of the upper layer of steel wool. The stainless steel mesh covers the upper layer of steel wool and positions it. The space between the bottom layer of steel wool and the upper layer of steel wool is used to store the granular coating agent.

[0005] As a preferred embodiment, the stainless steel mesh and the upper layer of steel wool are connected together.

[0006] As a preferred embodiment, the housing includes a lower cavity at the bottom and an upper cavity at the top. The inner diameter of the lower cavity is smaller than that of the upper cavity. The bottom of the upper cavity forms an annular stepped surface on the inner wall of the housing. A storage tube is inserted into the upper cavity. The outer wall of the storage tube is attached to the inner wall of the upper cavity. A bottom ring is connected to the lower end of the storage tube. The inner diameter of the bottom ring is not smaller than that of the lower cavity. The bottom ring is flat against the stepped surface. The top of the storage tube extends to the upper opening of the housing and is connected to an outwardly extending top ring. The top ring is attached to the top surface of the housing. The upper layer of steel wool is placed inside the storage tube. The bottom surface of the upper layer of steel wool is supported by the bottom ring. The stainless steel mesh is embedded inside the storage tube.

[0007] As a preferred option, the four edges of the carbon fiber cloth are sandwiched between the top surface of the bottom ring and the upper layer of steel wool.

[0008] As a preferred embodiment, the stainless steel mesh is fixedly connected to the storage cylinder.

[0009] As a preferred embodiment, a shielding ring is provided above the stainless steel mesh, with a central hole for the coating vapor to pass through.

[0010] The beneficial effects of this utility model are: by adding carbon fiber cloth to block the agent and adjusting the evaporation rate with upper steel wool, the granular agent remains stable during the vapor deposition process, preventing splashing and ensuring the vapor deposition effect. The density of the upper steel wool directly controls the agent evaporation rate, ensuring the density of the coating. The upper steel wool can be replaced and adjusted as needed to change the agent evaporation rate and adjust the coating effect.

[0011] This invention also ensures the stability of the upper layer of steel wool by setting a stainless steel mesh. Attached Figure Description

[0013] The specific implementation scheme of this utility model will now be described in detail with reference to the accompanying drawings. Example 1

[0014] like Figure 1The carrier of a granular vacuum coating agent shown includes a heat-conducting shell 1 with an open top. Inside the shell 1, there is a bottom layer of steel wool 2, and an upper layer of steel wool 3. A stainless steel mesh 4 is placed above the upper layer of steel wool 3. The bottom layer of steel wool 2 is tightly embedded in the bottom of the shell 1. The density of the bottom layer of steel wool 2 is higher than that of the upper layer of steel wool 3. The density of the upper layer of steel wool 3 is adjusted according to the evaporation rate of the agent. The density refers to the size of the air gap inside the steel wool. The higher the density, the worse the air permeability, and the lower the density, the better the air permeability. The upper layer of steel wool 3 is tightly attached to the inner walls of the shell 1. A layer of carbon fiber cloth 5 is attached to the bottom surface of the upper layer of steel wool 3. A stainless steel mesh 4 covers the upper layer of steel wool 3 to position it. The space between the bottom layer of steel wool 2 and the upper layer of steel wool 3 is used to store granular coating agents. The carbon fiber cloth 5 covers the agent to shield it and prevent the agent from splashing.

[0015] The bottom layer of steel wool 2 primarily serves as a heat conductor, heating the medicine above it and causing it to evaporate. Depending on the required evaporation rate, the user can replace it with an upper layer of steel wool 3 of suitable precision.

[0016] To improve the ease of removing the upper layer of steel wool 3, it is preferable to connect the stainless steel mesh 4 and the upper layer of steel wool 3 together.

[0017] The working process of this embodiment is as follows: Figure 1 As shown, first, the bottom layer of steel wool 2 is filled into the bottom of the shell 1 and pressed tightly. Then, granular reagent 13 is filled in. Next, carbon fiber cloth 5 is covered on top of the reagent 13. Then, the upper layer of steel wool 3 with appropriate density is selected and filled into the shell 1 and pressed tightly on the carbon fiber cloth 5. Finally, stainless steel mesh is pressed onto the upper layer of steel wool 3, thus completing the reagent filling for use in vacuum evaporation. Example 2

[0018] This embodiment is a further improvement upon embodiment 1. For example... Figure 2 and Figure 3As shown, the housing 1 includes a lower cavity 6 at the bottom and an upper cavity 7 at the top. The lower cavity 6 and the upper cavity 7 are coaxially arranged and interconnected. The inner diameter of the lower cavity 6 is smaller than that of the upper cavity 7. The bottom of the upper cavity 7 forms an annular stepped surface 8 on the inner wall of the housing 1. A storage tube 9 is inserted into the upper cavity 7. The outer wall of the storage tube 9 is attached to the inner wall of the upper cavity 7. A bottom ring 10 is connected to the lower end of the storage tube 9. The inner diameter of the bottom ring 10 is not smaller than that of the lower cavity 6. The bottom ring 10 is flush with the stepped surface 8. The top of the storage tube 9 extends to the upper opening of the housing 1 and is connected to an outwardly extending top ring 11. The top ring 11 is attached to the top surface of the housing 1. The upper layer of steel wool 3 is placed inside the storage tube 9. The bottom surface of the upper layer of steel wool 3 is supported by the bottom ring 10. The stainless steel mesh 4 is embedded in the storage tube 9. The four edges of the carbon fiber cloth 5 are sandwiched between the top surface of the bottom ring 10 and the upper layer of steel wool 3.

[0019] By setting up a storage cylinder 9, the carbon fiber cloth 5, the upper layer of steel wool 3, and the stainless steel mesh 4 are all stored inside the storage cylinder 9, which improves the convenience of loading the medicine. When loading the medicine, it is not necessary to take out each of the upper parts one by one. Instead, the carbon fiber cloth 5, the upper layer of steel wool 3, and the stainless steel mesh 4 inside the storage cylinder 9 can be taken out together by simply lifting the storage cylinder 9 through the top ring 11, which improves the efficiency of assembly and disassembly and avoids missing parts.

[0020] In this embodiment, it is also preferable to fix the stainless steel mesh 4 to the storage tube 9. This makes the storage tube 9 and its internal components form a whole, thus ensuring the structural stability of the components. When the user needs to replace the upper layer of steel wool 3, they can simply replace the storage tube 9 with one that has an upper layer of steel wool 3 of suitable precision.

[0021] In this embodiment, a shielding ring 12 is preferably provided above the stainless steel mesh 4, with a central hole for the coating vapor to pass through. The shielding ring 12 can further reduce the ventilation channel to decrease the evaporation efficiency of the agent and increase the diffusion rate of the agent vapor.

[0022] The working process of this embodiment is as follows: Figure 2 As shown, when filling the granular agent 13, the user only needs to pull the storage cylinder 9 out of the housing 1, then fill the housing 1 with the granular agent 13, ensuring that the top surface of the granular agent 13 is not higher than the step surface 8, and then insert the storage cylinder 9 back into the housing 1 to complete the agent filling, which is then ready for use during vacuum evaporation.

[0023] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some examples of its application, and are not intended to limit the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
