[0031] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of a specific embodiment of the vacuum coating equipment for strip substrates provided by the present invention.

[0032] A specific embodiment of the present invention provides a vacuum coating device for a strip substrate, comprising an upper cavity unit 1, a lower cavity unit 2 and a vacuum unit 3, wherein the upper cavity unit 1 and the lower cavity unit 2 can cooperate with each other, and the two are close to each other and snap together to form a closed coating space, and the coating space is used to place the strip substrate. At the same time, a coating device is installed in the coating space, and the vacuum unit 3 is connected to the coating space, and the vacuum unit 3 can extract the air in the coating space to form a vacuum environment in the coating space.

[0033] During the working process, the strip substrate to be coated is placed on the lower cavity unit 2, and the upper cavity unit 1 is buckled downward to cover the strip substrate on the lower cavity unit 2, so that the strip substrate is located in the closed coating space, and the vacuum unit 3 is started to form a vacuum environment in the coating space, and the coating device is started to coat the strip substrate. After the coating is completed, the vacuum environment is broken, and the upper cavity unit 1 is opened to take out the coated strip substrate to proceed with the coating of the next workpiece.

[0034] The surface of the strip substrate is coated by vacuum coating, which can effectively avoid scratching the surface of the strip substrate and is not easy to generate bubbles, thereby greatly improving the production efficiency of the strip substrate and reducing labor costs.

[0035] Please refer to Figure 2 and Figure 3 , Figure 2 This is a structural schematic diagram of an upper cavity unit in a specific embodiment of the vacuum coating device for strip substrates provided by the present invention; Figure 3 This is a structural schematic diagram of an upper sealed cavity assembly hidden in an upper cavity unit in a specific embodiment of the vacuum coating equipment for strip substrates provided by the present invention.

[0036] In the strip substrate vacuum coating equipment provided in a specific embodiment of the present invention, the upper cavity unit 1 includes a fixed base frame 11, an upper sealed cavity assembly 12, a cavity lifting assembly 13, a cavity pressing assembly 14 and an attachment roller assembly 15, wherein the fixed base frame 11 is two symmetrically arranged vertical brackets, the bottom of the brackets are fixed in position by a fixed plate, and there is a gap between the two brackets. The other components of the upper cavity unit 1 are arranged between the two brackets, and the two brackets are made to span above the lower cavity unit 2.

[0037] The cavity lifting assembly 13 is fixedly installed on the top of the two brackets of the fixed base frame 11 to form a portal structure. The upper sealed cavity assembly 12 is connected to the cavity lifting assembly 13. At the same time, the cavity lifting assembly 13 is connected to the attachment roller assembly 15 through the cavity pressing assembly 14. The upper sealed cavity assembly 12 is the upper cavity of the coating space, and the attachment roller assembly 15 is located in the upper sealed cavity assembly 12.

[0038] The chamber lift assembly 13 is used to drive the upper sealed chamber assembly 12 to move up and down. When the upper sealed chamber assembly 12 moves downward, it engages with the lower chamber unit 2, forming a closed film laminating space. When the upper sealed chamber assembly 12 moves upward, it separates from the lower chamber unit 2, facilitating the entry and exit of strip substrates. The chamber press-down assembly 14 is used to drive the attachment roller assembly 15 to move up and down, pressing the attachment roller assembly 15 against the strip substrate and applying the film to the strip substrate.

[0039] Please refer to Figure 4 , Figure 4 This is a structural schematic diagram of an upper sealing cavity assembly in a specific embodiment of the vacuum coating equipment for strip substrates provided by the present invention.

[0040] Specifically, the upper sealing assembly includes a sealing box 121 and a box rib 122, wherein the sealing box 121 is a box structure with an open lower end, the attachment roller assembly 15 is located in the sealing box 121, and the four box ribs 122 are installed at the four corners of the upper end surface of the sealing box 121, and the cavity lifting assembly 13 is connected through the box ribs 122. Furthermore, an electrical proportional valve 123, a pressure reducing valve 124 and a vacuum breaking solenoid valve 127 are provided on the upper panel of the sealing box 121. The electrical proportional valve 123 can adjust the pressure in the coating space to ensure a stable air pressure. The pressure reducing valve 124 can reduce the air pressure in the coating space to prevent excessive air pressure from damaging the coating of the strip substrate. When the coating of the strip substrate is completed, the vacuum breaking solenoid valve 127 is required to break the vacuum in the cavity, thereby facilitating the unloading of the strip substrate. A vacuum welding pipe 126 is provided on the side panel of the sealing box 121 to connect the upper sealing cavity assembly 12 with the vacuum pumping unit 3. Transparent organic glass 125 is installed around the sealing box 121 to facilitate observation of the internal working conditions.

[0041] Please refer to Figure 5 and Figure 6 , Figure 5 This is a schematic front view of a cavity lifting assembly in a specific embodiment of the vacuum coating device for strip substrates provided by the present invention; Figure 6 This is a structural schematic diagram of a cavity lifting assembly in a specific embodiment of the vacuum coating equipment for strip substrates provided by the present invention.

[0042] Furthermore, the cavity lifting assembly 13 includes a vertically arranged guide rail 131, a horizontally arranged mounting plate 136 and an upper support plate 137. The four guide rails 131 are installed on the inner side of the fixed base frame 11. Each box rib 122 is connected to each guide rail 131 through a slider and moves up and down along the guide rail 131. The upper end of the fixed base 11 supports the two ends of the upper support plate 137, and two transversely extending reinforcing ribs 138 are provided on the upper support plate 137 to improve the strength of the equipment, increase the load capacity of the upper support plate 137, and prevent the upper support plate 137 from being easily deformed. A motor seat 135 is installed on the upper support plate 137, and the lifting motor 134 is installed on the motor seat 135. The output end of the lifting motor 134 is connected to the mounting plate 136 through the screw assembly 132, and drives the mounting plate 136 to move up and down along the guide rail 131, driving the mounting plate 136 to be located below the upper support plate 137, and the cavity downward pressure assembly 14 is installed on the mounting plate 136. Preferably, four mounting ribs 133 are provided at the four corners of the mounting plate 136, and the four guide rails 131 are connected through the mounting ribs 133.

[0043] The cavity pressure assembly 14 includes a lift cylinder 141, a vertically arranged first guide shaft 142, and a second guide shaft 143. The lift cylinder 141 is fixed to the mounting plate 136. The two sets of lift cylinders 141 are connected to the attachment roller assembly 15 via the first guide shaft 142, driving the attachment roller assembly 15 up and down. This generates pressure when the attachment roller assembly 15 presses down on the strip substrate, ensuring that the film is completely adhered to the strip substrate. Simultaneously, the lower end of the second guide shaft 143 is connected to the upper sealed cavity assembly 12, guiding its upward and downward movement. The upper end of the second guide shaft 143 passes through the mounting plate 136 and is connected to a buffer 144, effectively acting as a buffer to prevent damage to the mechanical mechanism caused by excessive impact forces.

[0044] Please refer to Figure 7 and Figure 8 , Figure 7 This is a structural schematic diagram of an attaching roller assembly in a specific embodiment of the strip substrate vacuum laminating device provided by the present invention; Figure 8 This is a schematic front view of an attaching roller assembly in a specific embodiment of the vacuum coating device for strip substrates provided by the present invention.

[0045] In the strip substrate vacuum coating device provided in the specific embodiment of the present invention, the attaching roller assembly 15 includes an attaching base plate 151, a clamping rubber roller 152, a lifting rubber roller 153 and a tensioning rubber roller 155. The attaching base plate 151 is installed in the sealed box 121 through the first guide shaft 142, and drives the attaching base plate 151 to move up and down in the sealed box 121.

[0046] A tensioning cylinder 156 is installed on the upper surface of the attached base plate 151, and a clamping rubber roller 152, a rolling drive assembly 157 and a tensioning motor assembly 158 are installed on the lower surface of the attached base plate 151. The lifting rubber roller 153 is connected below the rolling drive assembly 157, and the horizontally arranged tensioning cylinder 156 is connected to the tensioning motor assembly 158. The tensioning rubber roller 155 is connected below the tensioning motor assembly 158, so that the tensioning rubber roller 155 and the clamping rubber roller 152 are located at the two ends below the attached base plate 151, and the lifting rubber roller 153 is located between the tensioning rubber roller 155 and the clamping rubber roller 152.

[0047] The clamping rubber roller 152 is used to clamp one end of the PET film 154. The PET film 154 then extends horizontally, with the other end passing over the tensioning rubber roller 155. The tensioning rubber roller 155 and the clamping rubber roller 152 spread the PET film 154 flat and open. When the attachment roller assembly 15 is laminating a strip substrate, the white PET film 154 is pressed against the thin film on the outer surface of the strip substrate. The lifting rubber roller 153 above the white PET film 154, driven by the rolling drive assembly 157, can move horizontally, thereby achieving a rolling and pressing function. The tensioning rubber roller 155 tensions the white PET film 154, maintaining a stable tension. The tensioning cylinder 156 controls the horizontal tension of the tensioning rubber roller 155, while the tensioning motor assembly 158 controls the vertical tension of the tensioning rubber roller 155. This allows the tensioning rubber roller 155 to tension the white PET film more freely and stably.

[0048] Please refer to Figures 9 to 11 , Figure 9 This is a structural schematic diagram of a lower cavity unit in a specific embodiment of the vacuum coating device for strip substrates provided by the present invention; Figure 10 This is a structural schematic diagram of the lower cavity alignment component in a specific embodiment of the strip substrate vacuum coating equipment provided by the present invention; Figure 11 This is a structural schematic diagram of a thin film cutting platform in a specific embodiment of the vacuum coating equipment for strip substrates provided by the present invention.

[0049] In the strip substrate vacuum laminating device provided in a specific embodiment of the present invention, the lower chamber unit 2 includes a lower chamber drive assembly 21, a lower chamber alignment assembly 22, and a film cutting platform 23. The lower chamber drive assembly 21 includes a first motor assembly 211 and a second motor assembly 212, which are respectively connected to the film cutting platform 23 and the lower chamber alignment assembly 22, and are used to drive the film cutting platform 23 and the lower chamber alignment assembly 22 to move horizontally, respectively. The lower chamber alignment assembly 22 is used for alignment adjustment before laminating the strip substrate, and the film cutting platform 23 is used for cutting the roll film. The two motor assemblies include a drive motor and a horizontal guide rail connected to the drive motor. The two horizontal guide rails are parallel to each other and support the lower chamber alignment assembly 22 and the film cutting platform 23, respectively, so that the lower chamber alignment assembly 22 and the film cutting platform 23 can move horizontally along the corresponding horizontal guide rails.

[0050] Furthermore, the lower cavity alignment assembly 22 includes a lower cavity sealing plate 221, a lower cavity bottom plate 223, a fine-tuning motor assembly 224, a rubber-coated vacuum suction plate 225 and a motor 226. The horizontally arranged lower cavity bottom plate 223 is connected to the second motor assembly 212, the fine-tuning motor assembly 224 is arranged on the lower cavity bottom plate 223, the fine-tuning motor assembly 224 is connected to the motor 226, and then the motor 226 is connected to the lower cavity sealing plate 221, so that the lower cavity sealing plate 221 is located above the lower cavity bottom plate 223, and large-diameter O-rings 222 are installed around the lower cavity sealing plate 221. The rubber-coated vacuum suction plate 225 is installed on the lower cavity sealing plate 221 and is surrounded by the large-diameter O-ring 222.

[0051] Specifically, the fine-tuning motor assembly 224 allows for fine horizontal adjustments to the motor 226. Combined with the rotational alignment of the motor 226 itself, this significantly improves the precision of the alignment of the strip substrate prior to lamination. When the upper chamber unit 1 is pressed downward and closed with the lower chamber unit 2, the large-diameter O-ring 222 enhances the sealing performance of the entire chamber. Because the rubber-coated vacuum suction plate 225 is coated with a layer of rubber on its upper surface, the strip substrate is adsorbed onto the rubber-coated vacuum suction plate 225 without damaging the surface.

[0052] The film cutting platform 23 includes a platform base plate 231, a film cutting drive motor assembly 232, a lower support plate 233, a platform top plate 234, a film cutting assembly 235 and a loading vacuum suction plate 236. The horizontally arranged platform base plate 231 is connected to the first motor assembly 211. The two lower support plates 233 are installed at both ends of the upper plate surface of the platform base plate 231, and the platform top plate 234 is installed on the lower support plate 233 to form a gap between the platform top plate 234 and the platform base plate 231. The loading vacuum suction plate 236 is installed on the upper plate surface of the platform top plate 234. The film cutting drive motor assembly 232 and the film cutting assembly 235 are installed in the gap between the platform base plate 231 and the platform top plate 234. The loading vacuum suction plate 236 is used to adsorb the film. The film cutting drive motor assembly 232 drives the film cutting assembly 235 to move horizontally. The film cutting assembly 235 is used to cut the film. Most of the films are in the form of a roll material. First, the film is loaded onto the loading vacuum suction plate 236. When the film is adsorbed, the film cutting assembly 235 cuts the loaded roll film.

[0053] Based on the strip substrate vacuum coating equipment provided in each of the above-mentioned specific embodiments, the vacuum unit 3 includes a cavity vacuum assembly, a cavity vacuum breaking assembly, a vacuum connecting pipe, and a vacuum pump. The cavity vacuum assembly and the cavity vacuum breaking assembly can respectively perform vacuuming and vacuum breaking processes on the coating space formed by the upper cavity unit 1 and the lower cavity unit 2. The vacuum pump and the cavity vacuum breaking assembly are connected via a vacuum connecting pipe. Through the vacuuming process of the vacuum pump, the strip substrate can be vacuum coated in the coating space formed by the upper cavity unit 1 and the lower cavity unit 2.

[0054] The specific working process is as follows: the sealing box 121 is separated from the lower chamber sealing plate 221, the laminating space is opened, and the strip substrate is placed on the rubber-coated vacuum suction plate 225 and suctioned. The film is placed on the loading vacuum suction plate 236 and suctioned. The film is stretched and stretched to cover the strip substrate. The position of the lower chamber sealing plate 221 is fine-tuned by the fine-tuning motor assembly 224 and motor 226, so that the strip substrate on the rubber-coated vacuum suction plate 225 is aligned with the attachment roller assembly 15 in the sealing box 121.

[0055] The lifting motor 134 works, and the sealing box body 121 is lowered through the screw assembly 132. The sealing box body 121 is buckled with the lower cavity sealing plate 221 to form a closed coating space, and is in close contact with the lower end edge of the sealing box body 121 through the large-diameter O-ring 222 to ensure the sealing effect. The vacuum unit 3 is started to form a vacuum environment in the coating space.

[0056] The lifting cylinder 141 works to make the attaching roller assembly 15 descend and press the strip substrate covered with the film, and through the cooperation of the rubber rollers, the PET film 154 is rolled onto the strip substrate to complete the lamination work, and the film cutting assembly 235 cuts the loaded roll film.

[0057] Finally, the vacuum is broken, and the components reverse their movements, separating the sealed box 121 from the lower chamber sealing plate 221 again. The laminating space is opened, and the material is unloaded. The operating drive components may also be of other types, such as cylinder drive or motor drive, depending on the situation. The supporting structures may also be adaptively adjusted, all within the scope of protection of the present invention.

[0058] The above describes in detail the strip substrate vacuum coating apparatus provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is intended only to facilitate understanding of the method and core concept of the present invention.
