Description

Technical Field

[0001] This utility model relates to the field of coating production equipment technology, and more specifically, to a flexible thin film vertical vacuum coating black light production system. Background Technology

[0002] Flexible thin films are common chemical products in daily life. Traditional optoelectronic thin film coating processes mostly use single methods, such as magnetron sputtering and chemical vapor deposition, which are relatively slow and can no longer meet the growing market demand. In terms of coating equipment, roll-to-roll coating equipment is gradually gaining attention due to its high production efficiency and excellent ability to produce flexible thin films.

[0003] Typical flexible thin film production equipment, such as the patent document CN202222341225.6 entitled "A Production Device for Flexible Conductive Thin Films," includes: a magnetron sputtering device and an unloading adjustment controller disposed outside the magnetron sputtering device. The magnetron sputtering device includes a cavity with an opening on one side wall and an insulating sleeve on the opening; a main roller shaft, one end of which is disposed on the side wall inside the cavity, and the other end extending through the opening and the insulating sleeve; a first coating main roller and a second coating main roller, respectively disposed on the main roller shaft inside the cavity; and the unloading adjustment controller is connected to the main roller shaft containing the first and second coating main rollers via a first wire. This is a magnetron sputtering type flexible thin film coating equipment.

[0004] However, conventional flexible films tend to be laid flat during coating, making them susceptible to contamination by settling impurities, thus compromising the coating effect. Furthermore, removing the product from the winding roller after coating is time-consuming and labor-intensive, failing to meet the demands of a rapidly evolving market. Utility Model Content

[0005] To address the issues of conventional thin-film coating equipment on the market, such as the film being easily contaminated by sedimented impurities when laid flat during operation, resulting in inconsistent coating quality, and the time-consuming and labor-intensive process of removing the product from the take-up roller after coating, we offer a flexible thin-film vertical vacuum coating black-light production system.

[0006] A flexible thin-film vertical vacuum coating black light production system includes a vertical chamber. From top to bottom, the vertical chamber contains an unwinding roller, a first coating assembly, and a winding roller. A material unloading assembly is located below the vertical chamber. The first coating assembly includes an evaporation coating chamber containing an evaporation boat and an evaporation baffle. An output chamber is connected to the outer side of the evaporation coating chamber corresponding to the upper surface of the evaporation baffle. A vertical shading net is located on the outer side of the output chamber, below the unwinding roller. Telescopic bushings are located on both sides of the winding roller.

[0007] Furthermore, a second coating assembly is provided between the first coating assembly and the take-up roller. The second coating assembly includes a deposition coating chamber with a transverse opening. A cathode arc evaporation source is provided in the deposition coating chamber and is connected to a gas storage tank. A sealing gate is provided at the opening of the deposition coating chamber, and a telescopic push plate is provided in front of the opening.

[0008] Furthermore, telescopic bushings are provided on both sides of the unwinding roller, and a feeding and unloading assembly is provided above the vertical chamber.

[0009] Furthermore, both the discharge loading and unloading assembly and the feed loading and unloading assembly include roller brackets, which are mounted on a translational lifting platform.

[0010] Furthermore, the outer side of the vertical cabin corresponds to the openings of the discharge loading and unloading components and the feed loading and unloading components, and each opening is equipped with a sliding sealing door.

[0011] Furthermore, the telescopic bushing is installed in the rotary bearing, and a rotary motor is connected to the rear of the telescopic bushing. Both the rotary bearing and the rotary motor are installed on the telescopic slide.

[0012] Furthermore, the vertical cabin is provided with an opening for the telescopic bushing to pass through, and a sealing gasket is provided around the opening.

[0013] Furthermore, the evaporation coating chamber is equipped with an electric heating element, the evaporation coating chamber is connected to a vacuum pump, and the deposition coating chamber is connected to a vacuum pump.

[0014] Furthermore, a driven roller shaft is provided below the unwinding roller, and the driven roller shaft is located close to the front end of the vertical shading net.

[0015] Furthermore, square protrusions are provided at both ends of the take-up roller, and a positioning groove with a cross-sectional shape corresponding to the square protrusions is provided on the inner side of the telescopic bushing.

[0016] The advantages of this utility model are:

[0017] 1. Flexible films are laid out vertically during coating, making them less prone to adhering to impurities that settle due to gravity.

[0018] 2. Equipped with an automatic loading and unloading mechanism, it automatically outputs finished products and allows for the replacement of new take-up rollers, resulting in high work efficiency.

[0019] 3. Workers do not need to wait for the coating to complete and then manually remove the finished product, which can reduce the workload of workers during production. Attached Figure Description

[0031] like Figures 1 to 4 As shown, this embodiment provides a flexible thin film vertical vacuum coating black light production system, including a vertical chamber 1. The vertical chamber 1 is provided with an unwinding roller 2, a first coating component 3 and a winding roller 5 arranged from top to bottom. A material unloading component is arranged below the vertical chamber 1. The first coating component 3 includes an evaporation coating chamber 301. An evaporation boat 302 and an evaporation baffle 303 are arranged in the evaporation coating chamber 301. An output chamber 304 is connected to the upper outer side of the evaporation coating chamber 301 corresponding to the evaporation baffle 303. A vertical shade net 305 is arranged on the outer side of the output chamber 304. The vertical shade net 305 is arranged below the unwinding roller 2. Telescopic bushings 7 are arranged on both sides of the winding roller 5.

[0032] Because the flexible film unfolds vertically downwards from the unwinding roller 2 and passes through the coating equipment before reaching the take-up roller 5 for rewinding, it is less prone to contamination by impurities that settle due to gravity during the coating process. After the coating process is completed, the flexible film is completely wound onto the take-up roller 5, and the telescopic sleeve 7 can release the take-up roller 5, which is then sent out by the unloading assembly. A new empty take-up roller 5 is then installed. No operator intervention is required, and the equipment can operate in the dark to reduce energy consumption and improve production efficiency.

[0033] A second coating assembly 4 is disposed between the first coating assembly 3 and the take-up roller 5. The second coating assembly 4 includes a laterally open deposition coating chamber 401, in which a cathode arc evaporation source 402 is disposed and connected to a gas storage tank 403. A sealing gate 404 is disposed at the opening of the deposition coating chamber 401, and a telescopic push plate 405 is disposed in front of the opening. In addition to the first coating assembly 3 being used for vacuum evaporation coating, the second coating assembly 4 can also be used for organic vapor deposition coating, and double-sided coating can be performed on both sides of the film, providing high flexibility.

[0034] Telescopic bushings 7 are provided on both sides of the unwinding roller 2, and a feeding and unloading assembly is provided above the vertical chamber 1. An automatic loading and unloading mechanism is provided at the take-up roller 5, and the same mechanism can be provided at the unwinding roller 2. The feeding and unloading assembly is generally ceiling-mounted.

[0035] Both the discharge and feed loading / unloading components include roller brackets 6, which are mounted on a translational lifting platform 601. The roller brackets 6 have slots to hold the rollers, and then a two-axis conveyor platform is used to feed the rollers into or out of the equipment without manual operation.

[0036] The outer side of the vertical chamber 1 corresponds to the openings of the discharge and feed loading / unloading components, and each opening is equipped with a sliding sealing door 8. In order to ensure the stability of the internal environment of the vertical chamber 1 during the coating process, sealing doors that can be automatically opened and closed are provided at the upper and lower ends of the vertical chamber 1.

[0037] The telescopic bushing 7 is installed in the rotary bearing 701, and a rotary motor 702 is connected to the rear of the telescopic bushing 7. Both the rotary bearing 701 and the rotary motor 702 are mounted on the telescopic slide 703. The telescopic bushing 7 can lock or unlock the roller shaft as the telescopic slide 703 moves, while the rotary motor 702 can drive the roller shaft to rotate, realizing synchronous unwinding and rewinding of the flexible film.

[0038] The vertical chamber 1 has an opening through which the telescopic sleeve 7 passes, and a sealing gasket is arranged around the opening. The sealing gasket improves the airtightness of the interior of the vertical chamber 1 and prevents the opening at the telescopic sleeve 7 from connecting to the outside and affecting the coating quality.

[0039] The evaporation coating chamber 301 is equipped with an electric heating element 9, which is connected to a vacuum pump 10, and the deposition coating chamber 401 is connected to a vacuum pump 11. The electric heating element 9 can heat the internal temperature of the vertical chamber 1 according to the coating requirements, while the vacuum pump 10 and the vacuum pump 11 can extract impurity gases from the vertical chamber 1, providing a vacuum environment that meets the requirements for coating.

[0040] A driven roller shaft 12 is disposed below the unwinding roller 2, and the driven roller shaft 12 is disposed close to the front end of the vertical shading net 305. In this embodiment, driven roller shafts 12 are disposed on both the upper and lower sides of the front end of the vertical shading net 305, so that the flexible film can move up and down close to the vertical shading net 305, ensuring that the vacuum evaporation coating is carried out smoothly.

[0041] The take-up roller 5 has square protrusions 501 at both ends, and the inner side of the telescopic bushing 7 has a positioning groove 704 with a cross-sectional shape corresponding to the square protrusions 501. The square protrusions 501, in conjunction with the positioning groove 704, can fix the take-up roller 5 in the telescopic bushing 7, preventing slippage during rotation. It is worth mentioning that the opening of the positioning groove 704 is funnel-shaped to prevent the square protrusions 501 from failing to properly fit into the positioning groove 704 due to misalignment.

[0042] In this embodiment, when the equipment is running, an uncoated flexible film roll is first loaded onto the unwinding roller 2, and the coating process is as follows:

[0043] I. Vacuum Evaporation Coating

[0044] The heating element 9 and vacuum pump 10 are started to heat the evaporation coating chamber 301 and remove the gas inside it. At this time, the sealing gate 404 closes the deposition coating chamber 401. When the temperature and pressure in the evaporation coating chamber 301 reach the standard, the source material on the evaporation boat 302 is started to evaporate. The evaporated gas enters the output chamber 304 and reaches the vertical shade net 305, where it is deposited on the flexible film at its front end. Each roller drives the film to wind around the roller at a speed of 0.3-0.5 m / s. When all films have been vapor-deposited, the evaporation coating process is stopped.

[0045] II. Organic vapor deposition coating

[0046] Open the sealing gate 404 to connect the deposition chamber 401 with the evaporation chamber 301 and the vertical chamber 1. The mixing of the evaporating gases will increase the gas pressure in the deposition chamber 401. At this time, turn on the vacuum pump 11 to maintain the gas pressure in the deposition chamber 401 at 1 Pa. At the same time, extend the telescopic push plate 405 to push the flexible film into the deposition chamber 401. When the temperature and pressure in the deposition chamber 401 reach the standard, open the gas storage tank 403. Organic gas is deposited through the discharge of the cathode arc evaporation source 402.

[0047] After coating is completed, the sliding sealing door 8 opens, the roller bracket 6 extends into the vertical chamber 1 to support the take-up roller 5, the telescopic bushing 7 releases the take-up roller 5, and then the roller bracket 6, carrying the take-up roller 5 wound with the coated flexible film, moves out of the vertical chamber 1 and replaces it with a new take-up roller 5. Similarly, the feeding and unloading assembly at the top of the equipment automatically replaces the unwinding roller 2 with a new one carrying the uncoated flexible film.

[0048] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be assumed that the specific implementation of the present utility model is limited to these descriptions. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present utility model.
