Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The accompanying drawings show preferred embodiments of the present invention. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

[0025] Unless otherwise specified, all raw materials, instruments and equipment used in this invention can be purchased from the market or prepared by existing methods.

[0026] Figure 1 This is an exploded structural diagram of the anti-splash vacuum winding coating device of this utility model. Figure 2 This is a perspective view of the installation of the anti-splash vacuum roll coating device of this utility model. (See reference) Figure 1-2 As shown, the anti-splash vacuum roll coating device includes a bottom support plate 6, a baffle assembly, and a surrounding plate assembly. The surrounding plate assembly is a rectangular frame structure with openings at the top and bottom. The surrounding plate assembly surrounds the upper edge of the bottom support plate 6. Multiple evaporation sources 7 are staggered on the bottom support plate 6. The evaporation sources 7 can be, for example, evaporation boats. The baffle assembly includes multiple parallel upper baffles. The multiple upper baffles are detachably installed on the inner wall of the surrounding plate assembly from top to bottom at intervals. Each upper baffle has multiple through holes.

[0027] In this embodiment of the utility model, the enclosure assembly includes two identical side support plates 4 and two identical side shielding plates 5 arranged symmetrically. The two side support plates 4 and the two side shielding plates 5 are perpendicularly connected to each other to form the rectangular frame structure with openings at the top and bottom.

[0028] For ease of assembly and disassembly, in this embodiment of the invention, the side support plate 4 and the side shielding plate 5 are fixed together by screws; the enclosure assembly and the bottom support plate 6 are fixed together by screws.

[0029] The side support plate 4 is provided with a plurality of support parts at intervals. The number of support parts is the same as the number of upper baffles. Each upper baffle is detachably installed on the support part.

[0030] In this embodiment of the utility model, the side support plate 4 is provided with three support parts at intervals, namely the first support part 41, the second support part 42 and the third support part 43, and the first support part 41, the second support part 42 and the third support part 43 are respectively provided with the first support mounting hole 44, the second support mounting hole 45 and the third support mounting hole 46.

[0031] In this embodiment of the utility model, the baffle assembly includes three parallel upper baffles, namely a first baffle 1, a second baffle 2, and a third baffle 3. The first baffle 1, the second baffle 2, and the third baffle 3 are respectively provided with a first positioning mounting hole 12, a second positioning mounting hole 22, and a third positioning mounting hole 32. The position and number of the first positioning mounting holes 12 correspond one-to-one with the position and number of the first support mounting holes 44. The first baffle 1 and the first support part 41 are screwed together through the first positioning mounting holes 12 and the first support mounting holes 44 using screws (not shown). The second positioning mounting hole 22 is positioned and numbered in a one-to-one correspondence with the second support mounting hole 45. The second baffle 2 and the second support part 42 are screwed together and fixed by screws (not shown) through the second positioning mounting hole 22 and the second support mounting hole 45. The third positioning mounting hole 32 is positioned and numbered in a one-to-one correspondence with the third support mounting hole 46. The third baffle 3 and the third support part 43 are screwed together and fixed by screws (not shown) through the third positioning mounting hole 32 and the third support mounting hole 46.

[0032] The first baffle 1 has a plurality of first through holes 11. The opening ratio of the first through holes 11 on the first baffle 1 (the ratio of the opening area of ​​the through hole to the area of ​​the upper baffle, the same below, will not be repeated) is 70% to 85%. The diameter of the first through hole 11 is proportional to the distance from the side support plate 4. That is, the closer the first through hole 11 is to the side support plate 4, the larger its diameter is. This can effectively improve the uniformity of the coating thickness and improve the density of the film surface.

[0033] The second baffle 2 has multiple second through holes 21 of the same size, and the opening ratio of the second through holes 21 on the second baffle 2 is 60% to 75%.

[0034] The third baffle 3 has multiple third through holes 31 of the same size, and the opening ratio of the third through holes 31 on the third baffle 3 is 40% to 60%.

[0035] In this embodiment of the invention, the opening positions of the third through hole 31 and the second through hole 21 are staggered, which can further avoid the problem of droplets splashing upwards.

[0036] Specifically, the baffle assembly in this embodiment of the invention comprises three upper baffles with different opening ratios. The third baffle 3 is the bottommost baffle, with an opening ratio of 40%–60% and uniform openings. The third baffle 3 is used to prevent upward splashing and damage to the base film. The second baffle 2 is the middle layer baffle, with an opening ratio further increased compared to the third baffle 3, ranging from 60% to 75%. The openings are uniform, and their positions are offset from those of the third baffle 3, primarily to further prevent upward splashing of molten metal droplets. The first baffle 1 is the top layer baffle, with an opening ratio of 70%–85%. The aperture size gradually decreases from both sides to the middle, exhibiting symmetry. The middle aperture is the smallest and has a higher distribution density. Its main function is to make the evaporation rate more uniform and the product more compact. The size of the through-holes corresponding to the three upper baffles in the baffle assembly can be adaptively adjusted according to the actual product quality. The size of the upper baffles can be selected according to the actual evaporation source 7 requirements; this invention does not limit this.

[0037] In this embodiment of the utility model, the baffle assembly and the surrounding plate assembly are both made of metal materials with low coefficient of thermal expansion, including tungsten alloy, 4J36 alloy (iron-nickel alloy), aluminum alloy, copper alloy, titanium alloy, etc., in order to reduce the impact of thermal expansion and contraction and facilitate subsequent disassembly and assembly.

[0038] In this embodiment of the utility model, the side shielding plate 5 is used to shield the side and cooperate with the side support plate 4 to prevent vapor from escaping and improve evaporation efficiency; the side shielding plate 5 is provided with a wire feeding hole 8, which is used to cooperate with the wire feeding mechanism 9 to realize the feeding of aluminum wire in the coating process.

[0039] The anti-splash vacuum roll coating device of this utility model uses a baffle assembly to shield the splashing of droplets and a surrounding plate assembly to block the escape of vapor. The structure is simple and reliable. It can not only avoid damage to the base film by droplet splashing, but also improve the density of the coating and improve product quality. At the same time, it reduces the adhesion of metal vapor to the inner wall of the vacuum chamber, reduces cleaning work, and protects the vacuum chamber.
