DETAILED DESCRIPTION

In order to better understand the above-mentioned technical scheme, the technical scheme of the embodiments of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the embodiments of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

As shown in Figures 1 to 4, an embodiment of the present application proposes a winding coating rewinding device, including: a pay-off roller 1, the pay-off roller 1 is used to release the substrate; a coating roller 2, the substrate is wound on the coating roller 2, the coating roller 2 is used to coat the substrate released by the pay-off roller 1, and obtain a coated film; an interlayer roller 3, the coated film is wound on the interlayer roller 3, the interlayer roller 3 is used to release the interlayer to cover the interlayer on the coating film, and obtain a coated product; a winding roller 4, the interlayer roller 3 is arranged close to the winding roller 4, the coated product is wound on the winding roller 4, and the winding roller 4 is used to store the finished product; a cooling component 5, the cooling component 5 is used to provide cooling for the interlayer roller 3.

The winding coating and winding equipment provided in the embodiment of the present application includes an unwinding roller 1, a coating roller 2, an interlayer roller 3, a winding roller 4 and a cooling assembly 5. During use, the unwinding roller 1 rotates to release the substrate, and the substrate is wound on the coating roller 2 for coating. The coated film obtained after coating passes through the interlayer roller 3, and the interlayer output by the interlayer roller 3 covers the coated film to obtain a finished coating product, and finally the finished coating product is stored on the winding roller 4. Based on this, through the setting of the interlayer roller 3, after the finished coating product is wound, an interlayer can be set between two adjacent layers of coated films. The interlayer can prevent the two adjacent layers of coated films from sticking to each other, reduce the probability of desorption of the coating and the substrate, and ensure the product yield.

The winding coating and winding equipment provided in the embodiment of the present application includes a cooling component 5. The cooling component 5 can be configured to cool the interlayer wound on the interlayer roller 3. The interlayer with a lower temperature can neutralize the residual heat of the coated film after the coating is completed, thereby avoiding heat accumulation of the film, further improving the connection strength between the coating and the substrate, further reducing the probability of desorption of the coating and the substrate, and ensuring the yield rate of the product.

In a feasible embodiment, the specific heat capacity of the interlayer is greater than or equal to 1.5 J/(g·K).

In this technical solution, parameters of the interlayer are further provided. The specific heat capacity of the interlayer is greater than or equal to 1.5 J/(g·K). Based on this, the interlayer is supported by a material with a high specific heat capacity. Before being released through the interlayer roller 3, it can fully absorb the cold. After being wound together with the coating film, it can continue to cool, which is beneficial to neutralize the residual heat in the coating film during the coating deposition process, avoid heat accumulation in the coating film, and can further improve the cooling effect, thereby reducing the probability of desorption of the coating and the substrate, thereby ensuring the product yield.

It is understandable that if the specific heat capacity of the interlayer is less than 1.5 J/(g·K), the cold storage capacity of the interlayer may be weak, resulting in a decrease in the cooling effect.

In a feasible embodiment, the material for preparing the interlayer includes one or more of polyvinyl alcohol, polyacrylamide, polyethylene, polyurethane, polypropylene, polystyrene, polytetrafluoroethylene, fluorinated polyethylene, fluorinated polypropylene, graphene and aluminum oxide.

In this technical solution, the interlayer is composed of one or more of polyvinyl alcohol (PVA), polyacrylamide (PAM), polyethylene (PE), polyurethane (PU), polypropylene (PP), polystyrene (PS), polytetrafluoroethylene (PTFE), fluorinated polyethylene, fluorinated polypropylene, graphene and alumina. Such a configuration can improve the mechanical strength of the interlayer and at the same time make the specific heat capacity of the interlayer greater than or equal to 1.5 J/(g·K), which is conducive to the preparation of the interlayer.

In a feasible embodiment, the water contact angle of the interlayer is greater than 100°, the roughness is less than 0.15, and the conductivity is greater than 10 ³ S/m.

In this technical solution, the parameters of the interlayer are further provided. The water contact angle of the interlayer is greater than 100° and the roughness is less than 0.15. During the use of the product, it is easy to peel off the interlayer and enable the interlayer to be smoothly separated from the coating film.

It can be understood that the surface of the interlayer is smooth and made of a hydrophobic material, and there is no O element on the surface, and no hydrophilic functional groups such as -OH and -COOH.

In this technical solution, the conductivity of the interlayer is greater than 10 ³ S/m. Such a configuration can increase the conductivity of the interlayer and reduce the accumulation of static electricity on the finished product.

As shown in Figures 1 to 4, in a feasible embodiment, the winding coating and reeling equipment also includes: a first coating member 6 and a second coating member 7, there are two coating rollers 2, one of which is arranged toward the first coating member 6, and the other coating roller 2 is arranged toward the second coating member 7, the first coating member 6 and the second coating member 7 are respectively coated on the first surface and the second surface of the substrate; wherein the cooling component 5 is also used to provide cooling for the coating roller 2.

In this technical solution, the winding coating winding equipment can also include a first coating component 6 and a second coating component 7, and the cooling component 5 is also used to provide cold energy for the coating roller 2. Based on this, during the working process, the coating roller is used to provide hard support to the flexible substrate and provide cold energy to relieve the heat of the coating deposition process; and the first coating component 6 and the second coating component 7 are used to provide gaseous coating materials to the flexible substrate, based on which the coating of the substrate can be completed.

It can be understood that, by providing the first coating member 6 and the second coating member 7 , both sides of the substrate can be coated.

In some examples, the first coating member 6 and the second coating member 7 may include an evaporation boat or a magnetron target.

As shown in Figures 1 to 4, in some examples, the winding coating and winding equipment can also include a vacuum chamber 11, and the unwinding roller 1, the coating roller 2, the interlayer roller 3, the winding roller 4 and the cooling component 5 can all be arranged in the vacuum chamber 11. The vacuum chamber 11 can provide a vacuum environment for the unwinding roller 1, the coating roller 2, the interlayer roller 3, the winding roller 4 and the cooling component 5 to ensure the coating quality.

As shown in Figures 1 to 4, in a feasible embodiment, the winding coating and reeling equipment also includes: a plurality of guide rollers 8, which are arranged on the circumferential sides of the unwinding roller 1, the coating roller 2, the interlayer roller 3 and the winding roller 4, and are used to guide the substrate or the coated film.

In this technical solution, the winding coating and reeling device may further include a plurality of guide rollers 8. The arrangement of the plurality of guide rollers 8 may guide the substrate or the coated film, which is beneficial to control the spatial layout of the film winding.

In some examples, the film winding and rewinding device may further include a flattening roller 9, which can flatten the film and improve the coating effect.

As shown in Figures 1 to 4, in some examples, the winding coating and winding equipment may also include: an evaporation source temperature regulating device 12, the evaporation source temperature regulating device 12 is connected to the first coating member 6 and/or the second coating member 7, and the output end of the cooling component 5 is connected to the evaporation source temperature regulating device 12, and the refrigeration temperature of the cooling component 5 can be adjusted by the evaporation source temperature regulating device 12.

In some examples, the film winding and rewinding device may further include a swing frame 13, through which the setting angle of the rewinding roller 4 can be adjusted to facilitate the rewinding.

As shown in Figures 1 to 4, in a feasible embodiment, the guide roller 8 closest to the sandwich roller 3 is the first guide roller 108, the line connecting the center of the first guide roller 108 and the center of the sandwich roller 3 is the first line, the line connecting the center of the winding roller 4 and the center of the sandwich roller 3 is the second line, and the angle between the first line and the second line is 15° to 75°.

In this technical solution, a layout relationship between the first guide roller 108, the interlayer roller 3 and the winding roller 4 is further provided, the line connecting the center of the first guide roller 108 and the center of the interlayer roller 3 is the first line, the line connecting the center of the winding roller 4 and the center of the interlayer roller 3 is the second line, and the angle between the first line and the second line is 15° to 75°. Such an arrangement can make the coated film adhere tightly to the cooled interlayer for a long time before being wound up, completely neutralize the heat stored in the film, thereby reducing the probability of desorption of the coating and the substrate, and ensuring the yield rate of the product.

In some examples, in the height direction, the interlayer roller 3 can be arranged between or outside the first guide roller 108 and the winding roller 4. When the interlayer roller 3 is arranged between the first guide roller 108 and the winding roller 4, the interlayer roller 3 is wrapped, which can reduce the loss of interlayer cold to the environment and enable more cold to be transferred to the film.

In a feasible embodiment, the winding coating winding device also includes: a controller, the controller is connected to the cooling component 5, and the controller is used to adjust the cooling temperature of the interlayer roller 3 based on the thickness of the interlayer wound on the interlayer roller 3; wherein the cooling temperature is positively correlated with the thickness of the interlayer wound on the interlayer roller 3.

The present application takes into account that the interlayer carries cold energy to cool the interlayer stored on the winding roller 4. As the unwinding proceeds, the outer diameter of the interlayer roller 3 will gradually decrease, and the distance the coated film is wound around will be reduced. At the same roller speed, the film's cooling time is reduced, and the coated film's temperature will increase, which will affect the quality of the finished product. Based on this, the controller is set to make the cooling temperature positively correlated with the thickness of the interlayer wound on the interlayer roller 3. That is to say, the lower the thickness of the interlayer winding, the lower the cooling temperature. This can ensure that the coated film can be effectively cooled under any working conditions, thereby ensuring the quality of the finished product.

In a feasible implementation manner, the controller adjusts the refrigeration temperature of the sandwich roller 3 by the following formula:

Wherein, T1 is the cooling temperature of the sandwich roller 3, T2 is the temperature of the coated film, θ is the central angle of the coated film around the sandwich roller 3, v is the movement speed of the coated film, σ is the thickness of the sandwich, λ is the thermal conductivity of the sandwich, D is the outer diameter of the sandwich roller 3, and C is a constant.

In this technical solution, a calculation formula for adjusting the refrigeration temperature of the sandwich roller 3 is further provided. By determining this formula, it is convenient to control through a controller, which is conducive to realizing intelligent production.

In this technical solution, by selecting the above formula, the cooling temperature of the interlayer roller 3 is related to the temperature of the coated film, the angle at which the coated film is wrapped around the interlayer roller 3, the movement speed of the coated film, the thickness of the interlayer, the thermal conductivity of the interlayer and the outer diameter of the interlayer roller 3. This can ensure the accuracy of the control of the cooling temperature of the interlayer roller 3, ensure that the coated film can be effectively cooled under any working conditions, and ensure the quality of the finished product.

It can be understood that σ is the thickness of the interlayer, which refers to the total thickness of all the interlayers wound on the interlayer roller 3; D is the outer diameter of the interlayer roller 3, which refers to the total diameter of the interlayer connected to the interlayer roller 3 and wound on the interlayer roller 3; C is the specific value of the cooling amount, because it is necessary to ensure that the cooling amount received by the film is consistent, so it is a constant, and the value can be 2 to 200, preferably 100. If the C value is too high, the cooling amount is large and the film becomes brittle. If it is too low, the cooling amount carried is too small, which is insufficient to achieve a good cooling effect.

In a feasible embodiment, the cooling assembly 5 includes: a cooling pipe, which is arranged in the sandwich roller 3; a coolant supply assembly, which is connected to the cooling pipe; wherein the controller is connected to the coolant supply assembly, and the cooling temperature of the sandwich roller 3 is adjusted by controlling the coolant supply speed and/or the supply temperature of the coolant of the coolant supply assembly.

In this technical solution, a style of a cooling component 5 is further provided. The cooling component 5 may include a cooling pipe coiled inside the sandwich roller 3. Cooling liquid can be supplied to the cooling pipe through a coolant supply component. The cooling temperature of the sandwich roller 3 is further adjusted by controlling the coolant supply speed and/or the supply temperature of the coolant of the coolant supply component, making the cooling temperature control of the sandwich roller 3 more convenient.

As shown in Figures 1 to 4, in a feasible embodiment, the cooling component 5 includes: a first shell 501 and a second shell 502, the first shell 501 and the second shell 502 are arranged in the sandwich roller 3, and the first shell 501 and the second shell 502 are both formed with a accommodating space, and the accommodating space is used to accommodate the phase change material; a driving member 503, the driving member 503 is connected to the first shell 501 and the second shell 502 to control the first shell 501 and the second shell 502 to be close to the inner wall of the sandwich roller 3; wherein the controller is connected to the driving member 503, and the cooling temperature of the sandwich roller 3 is adjusted by controlling the distance between the first shell 501 and the second shell 502 and the inner wall of the sandwich roller 3.

In this technical solution, another style of cooling component 5 is further provided. The cooling component 5 may include a first shell 501 and a second shell 502 arranged inside the sandwich roller 3. By accommodating phase change material in the two shells, refrigeration can be performed by utilizing the phase change of the phase change material. The distance between the first shell 501 and the second shell 502 and the inner wall of the sandwich roller 3 can be adjusted by the driving component. The closer the distance, the stronger the cooling effect. On the contrary, the farther the distance, the worse the cooling effect. Based on this, the cooling temperature of the sandwich roller 3 can be adjusted by controlling the distance between the first shell 501 and the second shell 502 and the inner wall of the sandwich roller 3. That is to say, the controller can control the driving position of the driving member 503 based on the rotation speed and time of the sandwich roller 3, thereby realizing the regulation of the cooling temperature of the sandwich roller 3, making the cooling temperature of the sandwich roller 3 more convenient.

In some examples, a guide member 505 may be formed on the inner wall of the sandwich roller 3, and a guide groove 504 may be formed on the first shell 501 and the second shell 502, and the guide member 505 may be inserted into the guide groove 504, thereby facilitating the movement of the first shell 501 and the second shell 502, and facilitating the first shell 501 and the second shell 502 to transport cold air to the sandwich roller 3.
