Description

Technical Field

[0001] The invention relates to the technical field of vacuum coating, in particular to a continuous vacuum coating device with a heating device. Background Art

[0002] Vacuum coating equipment mainly refers to a type of coating that needs to be carried out under a high vacuum degree. There are many types, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition, etc. The main idea is to divide it into two types: evaporation and sputtering. Evaporation coating generally heats the target material to evaporate the surface components in the form of atomic groups or ions, and settles on the surface of the substrate to form a thin film through the film forming process (scattered points-island structure-vagal structure-layered growth). Plating aluminum oxide on the surface of the film can produce a high-barrier transparent film.

[0003] In order to prevent the roller from scratching the coating on the surface of the film, the existing continuous vacuum coating equipment with a heating device will generally coat one side first when coating the film on both sides. After the coating is completed, the film is removed and reinstalled to coat the other side. This coating method makes it difficult to freely switch the required coating surface, which greatly reduces the production efficiency. To this end, we propose a continuous vacuum coating equipment with a heating device. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention provides a continuous vacuum coating device with a heating device, which solves the problem that it is difficult to freely switch the coating surface without affecting the integrity of the coating layer when using the existing continuous vacuum coating device. The film is wound on the sixth roller, and the middle part is along the attached Figure 2 The path shown in the figure is fitted and guided with the outer walls of the second roller, the third roller, the fourth roller and the fifth roller in turn, and finally the top of the film is fixed to the surface of the first roller, and then the lifting box is moved up to a position close to the third roller, and the interior is evacuated through the machine body, and the coating raw materials inside the heating box are heated and evaporated. The target material rises to the position of the opening at the upper end of the lifting box and the coating operation can be performed on the lower side of the film. Starting the driving motor can drive the first roller to rotate, and one end of the film is continuously pulled, and gradually wound from the sixth roller to the first roller. In this process, the film passing through the upper side of the lifting box will complete the single-sided coating.

[0016] 2. The present invention provides a continuous vacuum coating equipment with a heating device. When it is necessary to coat the other side, the lifting box is first moved down to the bottom, the blocking plate blocks the opening of the lifting box, the first electric telescopic rod is started, the sliding plate is pushed to slide in the gas pipe, and the gas in the gas pipe is transported to multiple groups of connecting pipes through the annular pipe. The increased air pressure in the connecting pipe pushes the push rod and the plug block to slide, and the plug block gradually fits the plug-in slot. At this time, the driving motor rotates in the opposite direction, driving the second gear and the device disk to reverse. During the reversal of the device disk, when the plug block is plugged into the plug-in slot, the limit is completed, and the rotating frame is driven to rotate together until the rotating frame rotates to the other side position, such as Fig.11 As shown, during this process, the third gear is still driven by the first transmission belt to rotate, and the third gear continuously rotates to complete the meshing during the process of fitting with the fifth gear. After that, the sixth gear meshes with the seventh gear during the rotation of the sixth gear, thereby driving the sixth roller to rotate. At the same time, a device capable of limiting the position of the rotating frame is provided on the limit plate. After the fixation is completed, the first electric telescopic rod is retracted, the gas in the connecting pipe is extracted, the plug-in block releases the plug-in limit with the plug-in slot, and the connecting frame no longer rotates.

[0017] 3. The present invention provides a continuous vacuum coating equipment with a heating device. The second electric telescopic rod is started and pushed out to push the connecting rod into the limiting groove. The fifth roller no longer blocks the opening of the sleeve box. At the same time, the film changes due to the positions of the fourth roller and the sixth roller. At this time, the path of the film is shown in Figure 10. At this time, the film is mainly wound on the first roller after completing single-sided coating. One side of the film is now in contact with the fourth roller and no longer in contact with the fifth roller. The surface originally in contact with the fifth roller is now in a position close to the opening of the sleeve box. The driving motor rotates in the opposite direction to move the first roller. The film on one roller is rewound onto the sixth roller, and the steam enters the fixed box through the connecting pipe and escapes through the opening of the sleeve box, so that the other side of the film can be coated. At this time, the film is transported from the first roller to the sixth roller. During the transportation process, the outer wall of the film is directly rolled up by the sixth roller after being coated, and there will be no contact and friction with other rollers. The device can flexibly switch the coating of different surfaces of the film without frequent disassembly of the film, which greatly improves the efficiency of coating. The switching process is simple and efficient. It only needs to be disassembled once after coating is completed, which is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The adjusting member 12 includes a second electric telescopic rod 39 fixedly mounted on the body 1, a return spring 40 fixedly connected to the fixed box 13 is fixedly connected to the socket box 14, both ends of the fourth roller 6 are rotatably connected to the connecting rod 41, both ends of the fifth roller 7 are rotatably connected to the connecting rods 41 on both sides, the output end of the second electric telescopic rod 39 is fixedly connected to the connecting rod 41, the fifth roller 7 can fit with the inner wall of the opening of the socket box 14, and both sides of the socket box 14 are provided with limit grooves 42 slidably connected to the connecting rod 41.

[0038] The coating mechanism 46 also includes a sealing plate 43 fixedly installed in the heating box 2, which can seal the opening of the lifting box 15. The side of the heating box 2 is connected to a connecting pipe 44, and one end of the connecting pipe 44 is connected to the fixed box 13.

[0039] In this embodiment, the film is wound on the sixth roller 8, and the middle part is along the attached Figure 2 The path shown in the figure is fitted and guided with the outer walls of the second roller 4, the third roller 5, the fourth roller 6 and the fifth roller 7 in sequence, and finally the top of the film is fixed to the surface of the first roller 3, and then the lifting box 15 is moved up to a position close to the third roller 5, and the interior is evacuated through the machine body 1, and the coating raw materials in the heating box 2 are heated and evaporated. The target material vapor rises to the position of the upper opening of the lifting box 15, and the coating operation can be performed on the lower side of the film. At this time, the rotating frame 10 is fitted and fixed with one side of the limiting plate 45, and the first The third gear 22 is meshed with the fourth gear 24. Starting the driving motor 16 can drive the first gear 17 to rotate, and the first gear 17 drives the second gear 19 and the device disk 18 to rotate, thereby driving the third gear 22 to rotate through the first transmission belt 23, and the third gear 22 drives the fourth gear 24 and the second transmission belt 25 to transmit, so that the first roller 3 rotates, and one end of the film can be continuously pulled, and gradually wound from the sixth roller 8 to the first roller 3. In this process, the film passing through the upper side of the lifting box 15 will complete single-sided coating.

[0040] It should be noted that: since the surface of the film that has just been coated has not yet been completely solidified, the coating is easy to fall off, and generally it needs to be left to stand or dried. At this time, if the surface is directly fitted with the roller during the transportation process, it will cause wear to the coating. Therefore, through the setting of the first roller 3, the second roller 4, the third roller 5, the fourth roller 6, the fifth roller 7 and the sixth roller 8, it is ensured that when the film is coated, the coated surface is always on the side away from the roller, which will not cause wear of the coating during the transportation and guiding process.

[0041] During this process, the first electric telescopic rod 37 and the second electric telescopic rod 39 are both in a retracted state, and there is a certain gap between the fourth roller 6 and the fifth roller 7, which ensures that the non-coated side of the film is only in contact with the outer wall of the fifth roller 7 at this time. At the same time, the pulling of the second electric telescopic rod 39 makes the fifth roller 7 in contact with the opening of the sleeve box 14, thereby blocking the opening of the sleeve box 14 to prevent a large amount of target material vapor from overflowing, so that only the opening position of the lifting box 15 can be used for coating operations.

[0042] When the other side needs to be coated, the lifting box 15 is first moved down to the bottom, the blocking plate 43 blocks the opening of the lifting box 15, and the first electric telescopic rod 37 is started to push the sliding plate 38 to slide in the gas pipe 35, and the gas in the gas pipe 35 is transported to the multiple groups of connecting pipes 32 through the annular pipe 36. The increased air pressure in the connecting pipe 32 pushes the push rod 33 and the plug block 30 to slide, and the plug block 30 gradually fits the plug slot 31. At this time, the driving motor 16 rotates in the opposite direction, driving the second gear 19 and the device disk 18 to reverse. During the reversal of the device disk 18, when the plug block 30 is plugged into the plug slot 31, the limit can be completed, and the rotating frame 10 can be driven to rotate together until the rotating frame 10 rotates to the other side position, such as Fig.11 As shown, during this process, the third gear 22 is still driven by the first transmission belt 23 to rotate. The third gear 22 continuously rotates to complete the meshing process with the fifth gear 27. The tooth size of the fifth gear 27 is larger than the tooth size of the sixth gear 28, which ensures that the fifth gear 27 and the third gear 22 are preferentially meshed. After that, the sixth gear 28 meshes with the seventh gear 29 during its rotation, which can drive the sixth roller 8 to rotate. At the same time, a device capable of limiting the position of the rotating frame 10 is provided on the limit plate 45. After the fixation is completed, the first electric telescopic rod 37 is retracted, the gas in the connecting pipe 32 is extracted, the plug block 30 releases the plug-in limit with the plug-in slot 31, and the connecting frame no longer rotates.

[0043] At the same time, the second electric telescopic rod 39 starts to push out, pushing the connecting rod 41 into the limiting groove 42, and the fifth roller 7 no longer blocks the opening of the sleeve box 14. At the same time, the film changes due to the position of the fourth roller 6 and the sixth roller 8. At this time, the path of the film is as follows Fig.10 As shown in the figure, after the single-sided coating is completed, the film is mainly wound on the first roller 3. One side of the film is now in contact with the fourth roller 6 and no longer in contact with the fifth roller 7. The surface that was originally in contact with the fifth roller 7 is now in a position close to the opening of the sleeve box 14. The driving motor 16 rotates in the opposite direction. At this time, the third gear 22 is no longer meshed with the fourth gear 24. The first roller 3 is no longer used as a driving wheel, but the sixth roller 8 is used as a driving wheel to rotate and rewind, and the film on the first roller 3 is rewound onto the sixth roller 8. At this time, steam is no longer emitted from the upper side of the lifting box 15. The steam enters the fixed box 13 through the connecting pipe 44 and is released through the opening of the sleeve box 14, so that the other side of the film can be coated. At this time, the film is transported from the first roller 3 to the sixth roller 8. During the transportation process, the outer wall of the film is directly rolled up by the sixth roller 8 after being coated, and will not be in contact with or rubbed against other rollers.

[0044] The device can flexibly switch the coating on different surfaces of the film without frequently disassembling the film, which greatly improves the efficiency of coating. The switching process is simple and efficient. After the coating is completed, it only needs to be disassembled once, which is convenient to use.
