Description

Technical Field

[0001] This utility model relates to the field of carbon fiber radiation thin films, and in particular to vacuum coating equipment for the production of carbon fiber radiation thin films. Background Technology

[0002] Vacuum coating equipment is a specialized device that converts solid materials into gaseous particles in a vacuum environment through physical or chemical methods and deposits them on the surface of a substrate to form a thin film. For details, please refer to a novel vacuum coating equipment with publication number CN218893736U.

[0003] However, in actual use, when the flexible base film moves continuously in the vacuum chamber, tension fluctuations can cause the film to wrinkle and shift laterally. Furthermore, the lack of an active flattening structure for the base film in the evaporation area makes it prone to local warping under high temperature conditions, which can not maintain a flat state and result in uneven film thickness. In addition, the lack of guiding measures makes it easy for metal powder to be sputtered into non-coated areas during the coating process, resulting in low coating accuracy and affecting coating quality.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[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] Please see Figure 1 - Figure 2 As shown, this embodiment is a vacuum coating equipment for producing carbon fiber radiation thin films, including a housing 1, a vacuum pump 11 fixedly installed on one side of the housing 1, and a vapor deposition chamber 12 fixedly installed on the top of the housing 1. The vacuum pump 11 is used to ensure the coating environment inside the housing 1. That is, when the vacuum pump 11 is started, the inside of the housing 1 gradually enters a vacuum state, thereby ensuring the smooth progress of the coating.

[0031] Inside the housing 1, a connecting frame 13 and a guide plate 14 are fixedly installed. A take-up roller 15, an unwind roller 16, and a support roller 17 are movably installed in the connecting frame 13. The take-up roller 15 and the unwind roller 16 are symmetrically arranged in the connecting frame 13. The support roller 17 is located above the take-up roller 15 and the unwind roller 16. A base film 18 is wound on the unwind roller 16. One end of the base film 18 passes through the surface of the support roller 17 and is fixedly connected to the take-up roller 15.

[0032] The guide plate 14 is located above the connecting frame 13. The cross-section of the guide plate 14 is a trapezoid with a larger top and a smaller bottom. The guide plate 14 separates the vapor deposition area from the base film 18 conveying area (e.g., Figure 2 As shown in the figure, specifically, the guide plate 14 divides the internal space of the equipment into two functional areas in a rigid separation manner: the upper part is the high-temperature evaporation reaction area and the lower part is the base film 18 conveying channel area. The guide plate 14 effectively blocks the downward diffusion of the radiative heat flow generated by the evaporation source, and avoids the high-temperature heat load from directly acting on the base film 18 in operation, thereby ensuring the thermal stability of the base film 18.

[0033] Meanwhile, a coating channel 141 is provided at the bottom center of the guide plate 14. The coating channel 141 is rectangular. A coating nozzle 121 is fixedly installed on the top of the box 1. The coating nozzle 121 is fixedly connected to the vapor deposition box 12. It should be noted that the box 1 also has the necessary structures for coating fixedly installed. These are all existing technologies, and their specific types and connection methods will not be described in detail here.

[0034] The coating nozzle 121 is located directly above the coating channel 141, and the support roller 17 is located at the coating channel 141 (e.g., Figure 2 As shown, the coating channel 141 is used to limit the coating area, preventing the metal powder evaporated from the coating nozzle 121 from being splashed onto the non-coating area when the coating nozzle 121 is working, thus effectively improving the accuracy of the coating work.

[0035] Example 2:

[0036] Please see Figure 3 - Figure 6 As shown, the present invention also includes a tensioning assembly 2, which includes a movable plate 21, a tensioning roller 22 movably disposed on the movable plate 21, and an adjusting block 23 movably disposed on the movable plate 21. The movable plate 21 is movably mounted on the connecting frame 13 and is symmetrically arranged on the connecting frame 13. The tensioning roller 22 is located on both sides of the support roller 17.

[0037] The connecting frame 13 includes two symmetrically arranged connecting plates 131 and a vertical plate 132 fixedly mounted on the top of the connecting plates 131. A horizontal plate 19 is fixedly installed on the side of the connecting plate 131 away from the take-up roller 15. The horizontal plate 19 is fixedly connected to the inner wall of the housing 1 (e.g., Figure 3 As shown), the vertical plate 132 is located at the top center of the connecting plate 131. The two ends of the support roller 17 are movably connected to the vertical plate 132. The two ends of the take-up roller 15 and the unwind roller 16 are movably connected to the connecting plate 131. A motor 27 is fixedly installed on the connecting plate 131. The output end of the motor 27 is fixedly connected to one end of the take-up roller 15. In actual use, the base film 18 roll is first fixedly installed on the unwind roller 16. After passing one end of the base film 18 through the surface of the support roller 17, it is fixedly connected to the take-up roller 15. When the motor 27 starts and drives the take-up roller 15 to rotate, the base film 18 begins to move, thereby realizing the continuous conveying of the base film 18.

[0038] Adjustment grooves 24 are provided on both sides of the vertical plate 132. The movable plate 21 is movably installed in the adjustment grooves 24. A limiting groove 25 is provided on the side of the adjustment groove 24 away from the support roller 17. A connecting rod 26 is movably installed in the limiting groove 25. One end of the connecting rod 26 is fixedly connected to the movable plate 21, and the other end of the connecting rod 26 away from the movable plate 21 is threadedly connected to the adjustment block 23 (e.g., Figure 5 As shown in the figure, the side of the adjusting block 23 near the limiting groove 25 abuts against the surface of the vertical plate 132. In the initial state, the moving plate 21 remains stable under the action of the adjusting block 23. When it is necessary to adjust the position of the tension roller 22, simply turn the adjusting block 23. Under the action of the thread, the adjusting block 23 moves on the connecting rod 26 until the adjusting block 23 separates from the vertical plate 132. At this time, pull the moving plate 21 to make it slide in the adjusting groove 24. After it is in place, turn the adjusting block 23 in the opposite direction so that one side abuts against the surface of the vertical plate 132. At this time, the moving plate 21 is locked, thereby adjusting the position of the tension roller 22 to adapt to various processing scenarios.

[0039] During the coating process, the tension roller 22 actively supports and adjusts the tension of the base film 18, effectively suppressing tension fluctuations when the base film 18 moves, significantly improving the continuity of the film layer. At the same time, through the linkage of the moving plate 21 and the adjusting block 23, the position of the moving plate 21 is adjusted, and then the tension roller 22 applies directional tension to the base film 18 in the coating area, forcibly eliminating wrinkles and warping of the base film 18, ensuring that the base film 18 remains flat during the coating process, and greatly improving the uniformity of the film layer.

[0040] The working process and principle of this utility model are as follows:

[0041] First, the base film 18 is conveyed by the take-up roller 15, the unwind roller 16 and the support roller 17, which cooperate with the guide plate 14 and the coating nozzle 121 to achieve continuous and uniform coating of the base film 18.

[0042] Furthermore, the guide plate 14 separates the vapor deposition area from the base film 18 conveying area, preventing the high-temperature heat load from directly acting on the base film 18 during operation, thereby ensuring the thermal stability of the base film 18. At the same time, it limits the coating area, preventing the vapor-deposited metal powder from being splashed to other parts of the equipment when the coating nozzle 121 is working, effectively improving the accuracy of the coating work.

[0043] Furthermore, through the tensioning component 2, during the coating process, the tensioning roller 22 actively supports and adjusts the tension of the base film 18, effectively suppressing tension fluctuations when the base film 18 moves, and significantly improving the continuity of the film layer.

[0044] Furthermore, by the linkage between the moving plate 21 and the adjusting block 23, the position of the moving plate 21 can be adjusted, and then the tensioning roller 22 is used to apply directional tension to the base film 18 in the coating area, forcibly eliminating wrinkles and warping of the base film 18, ensuring that the base film 18 remains flat during the coating process, and greatly improving the uniformity of the film layer.
