Description

Technical Field

[0001] This invention relates to the field of glass production, processing, cleaning and packaging technology, and in particular to a glass nano-coating device and coating method. Background Technology

[0002] The principle of glass nanocoating is to use nanomaterials to automatically form a thin film on the glass surface, and the effect is to use the activity of nanomaterials to purify the air.

[0003] Coating glass surfaces with nanomaterials represents a novel approach and perspective, for which there is currently no readily available equipment or technology. This solution utilizes robotic spraying, adaptable to various glass sizes, and can be integrated alongside existing glass production lines.

[0004] The nanomaterials are applied using a coating, uniform application, and rapid drying process, minimizing human intervention. Furthermore, glass production is completed in a non-contact manner across these three steps. This process is well-suited for fast-paced glass production lines. Summary of the Invention

[0005] To address the problem that existing coating mechanisms cannot meet the requirements of nano-coating, this invention provides a glass nano-coating device and coating method for a glass production line with good coating effect.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] A glass nanofilm coating device, comprising:

[0008] A spraying device that sprays a nano-coating liquid onto glass.

[0009] A homogenizing coating device, wherein the homogenizing coating device uses compressed air to homogenize the water mist on the glass surface and remove excess water mist droplets;

[0010] A heat curing device, wherein the heat curing device uses hot air to heat and cure the glass surface;

[0011] The tool mounting base is on which the spraying device, the homogenizing coating device, and the heating curing device are mounted.

[0012] The drive mechanism drives the tool mounting base to move.

[0013] Furthermore, it also includes a coating robot, which is set on one side of the conveying equipment, and the tool mounting base is installed at the end of the robotic arm of the coating robot.

[0014] Furthermore, the coating robot is a six-axis industrial robot.

[0015] Furthermore, the spraying device includes a plurality of atomizing nozzles disposed on the tool mounting base.

[0016] Furthermore, the homogenizing coating device includes an air knife mounted on a tool mounting base.

[0017] Furthermore, the heating and curing device includes an air blowing device mounted on the tool mounting base, the air blowing device having a plurality of air jet holes, the air jet holes being connected to hot air.

[0018] Furthermore, it also includes at least one position detection mechanism for detecting the glass conveying position. When the glass moves to the set position, the robotic arm begins to perform spraying, homogenizing coating, and heat curing.

[0019] A coating method for a glass nanofilm coating device as described above includes the following steps:

[0020] S1: The glass is transported to the front of the coating robot by the conveying equipment. The position detection mechanism detects the glass, and the coating robot drives the tool mounting base to move. At the same time, the spraying device sprays the nano coating liquid along the spraying path.

[0021] S2: After the spraying operation is completed, the air knife sprays compressed air along the coating path to homogenize and coat the coating liquid on the glass surface and remove excess water droplets to form a coating layer.

[0022] S3: After the coating process is completed, the air jet nozzles of the blowing device spray hot air along the curing path to heat and cure the coating layer.

[0023] The spray path, coating path, and curing path are parallel to the length and / or width of the glass.

[0024] Furthermore, in S1, the spray parameters are first matched by software, and the offset is calculated using the following function:

[0025] [Zn1, Zm1] = FUNC_Z1{[Z, A], [P1, Q1, Φ1], [H1], [α1]}[Xn1, Xm1] = FUNC_X1{[X, A], [P1, Q1, Φ1], [H1], [α1]}, where Zn1 is the number of offsets in the height direction, Zm1 is the offset interval in the height direction, Z is the height of the glass, A is the spray width, P1 is the spray negative pressure, Q1 is the spray flow rate, Φ1 is the particle size, H1 is the vertical distance between the atomizing nozzle and the glass surface, α1 is the tilt angle of the tool mounting base during spraying, Xn1 is the number of offsets in the width direction, Xm1 is the offset interval in the width direction, and X is the width of the glass.

[0026] The robot generates a spray path based on offset parameters in the height and width directions:

[0027] [Route1, V1]=FUNC_Route1{[Zn1, Zm1], [Xn1, Xm1]}

[0028] Where Route1 is the spray path and V1 is the spray speed;

[0029] In S2, the coating parameters are first matched using software, and the offset is calculated using the following function:

[0030] [Zn2, Zm2] = FUNC_Z2{[Z, B], [P2, Q2], [H2], [α2]}; [Xn2, Xm2] = FUNC_X2{[X, B], [P2, Q2], [H2], [α2]}; where Zn2 is the number of offsets in the height direction, Zm2 is the offset interval in the height direction, Z is the height of the glass, B is the coating width, P2 is the coating air pressure, Q2 is the air flow rate, H2 is the vertical distance between the air knife and the glass surface, α2 is the tilt angle of the tool mounting base during coating; Xn2 is the number of offsets in the width direction, Xm2 is the offset interval in the width direction, and X is the width of the glass;

[0031] The robot generates a coating path based on offset parameters in the height and width directions:

[0032] [Route2, V2] = FUNC_Route2{[Zn2, Zm2], [Xn2, Xm2]}, where Route2 is the coating path and V2 is the coating speed;

[0033] In S3, the solidification parameters are first matched using software, and the offset is calculated using the following function:

[0034] [Zn3, Zm3]=FUNC_Z3{[Z, B], [P3, Q3], [H3], [α3]}

[0035] [Xn3, Xm3]=FUNC_X3{[X, B], [P3, Q3], [H3], [α3]}

[0036] Where Zn3 is the number of offsets in the height direction, Zm3 is the offset interval in the height direction, Z is the height of the glass, B is the curing width, P3 is the hot air pressure, Q3 is the air flow rate, H3 is the vertical distance between the air jet and the glass surface, α3 is the tilt angle of the tool mounting base during curing; Xn3 is the number of offsets in the width direction, Xm3 is the offset interval in the width direction, and X is the width of the glass.

[0037] The robot generates the curing path based on offset parameters in the height and width directions:

[0038] [Route3, V3]=FUNC_Route3{[Zn3, Zm3], [Xn3, Xm3]}

[0039] Where Route3 is the curing path and V3 is the curing speed.

[0040] Beneficial effects:

[0041] (1) By setting up a nano-coating device next to the glass conveying equipment, the present invention is equivalent to embedding the nano-coating device into the existing glass production line, without the need for an additional coating process, thereby improving the glass processing efficiency.

[0042] (2) The nano-coating liquid is sprayed onto the glass through an atomizing nozzle, then uniformly coated by an air knife, and finally cured by hot air blown out by an air blowing device, which can ensure the uniformity of the coating and the curing effect.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0059] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0060] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description.

[0063] A glass nanofilm coating device, such as Figures 1-3 The device includes a spraying device, a homogenizing coating device, a heating and curing device, a tool mounting base 7, and a drive mechanism: the spraying device sprays a nano-coating liquid onto the glass 1; the homogenizing coating device uses compressed air to homogenize the water mist on the surface of the glass 1 and remove excess water mist droplets; the heating and curing device uses hot air to heat and cure the surface of the glass 1; the spraying device, the homogenizing coating device, and the heating and curing device are mounted on the tool mounting base 7, and the drive mechanism drives the tool mounting base 7 to move.

[0064] It also includes a coating robot 3, which is positioned on one side of the conveying device 2. A tool mount 7 is mounted at the end of the robotic arm of the coating robot 3, and the tool mount 7 is driven to move by the robotic arm. The coating robot 3 is optional, but not limited to, a six-axis industrial robot.

[0065] The spraying device includes several atomizing nozzles 4 mounted on the tool mounting base 7. The homogenizing coating device includes an air knife 5 mounted on the tool mounting base 7. The air blown out by the air knife 5 is cold air.

[0066] The heating and curing device includes an air blowing device 6 mounted on a tool mounting base 7. The air blowing device 6 has several air jet holes, which are connected to hot air.

[0067] It also includes at least one position detection mechanism for detecting the conveying position of glass 1.

[0068] A coating method for the above-mentioned glass nanofilm coating device, such as Figure 4 This includes the following steps:

[0069] S1: Glass 1 is transported by conveyor 2 to the front of coating robot 3. The position detection mechanism detects glass 1, and coating robot 3 drives tool mounting base 7 to move. Simultaneously, the spraying device sprays nano-coating liquid along the spray path. Previously, manual spraying using a handheld sprayer was discontinuous, with inconsistent spraying height, resulting in uneven spraying and poor performance. This solution allows the robot to adjust the tool mounting base height based on the glass's height and width, as well as the varying tilt angle β caused by different glass heights. This ensures the nozzle maintains a consistent distance H1 from the glass and a tilt angle α1 during operation. This results in better, more uniform, and continuous spraying.

[0070] S2: After the spraying process is complete, the air knife 5 sprays compressed air along the coating path to evenly coat the coating liquid on the glass 1 surface and remove excess water droplets, forming a coating layer. Previously, after manual hand-held spraying, a sponge was used to spread the coating evenly, leaving smear marks on the glass. It is particularly important to note that if too much is sprayed or the coating is uneven, the nanomaterial liquid, due to its inherent properties, will oxidize with the air, precipitating white crystals and forming white marks. This solution uses high-speed and high-pressure gas to blow away excess liquid from the glass surface, achieving a uniform coating effect without leaving marks or contacting the glass – this is the biggest innovation of this solution. Based on experience, during operation, the vertical distance between the air knife 5 and the glass 1 surface is relatively small, and the α2 tilt angle is relatively large, which is beneficial for cleaner removal. However, there is no need to worry that once the nanomaterial comes into contact with the glass surface, it automatically forms a coating layer, removing excess liquid, but not completely removing it.

[0071] S3: After the coating process is completed, the air blowing device 6 sprays hot air from the air jet holes along the curing path to heat and cure the coating layer.

[0072] In manual operation, a blower is typically used to manually heat the glass. This solution allows for continuous, uniform heating, achieving rapid heating and curing of the nano-coating on the glass surface without affecting the glass production line's cycle time. In this case, H3 will be relatively large, while α3 is generally not required; α3 = α1 is sufficient.

[0073] The spray path, coating path, and curing path are parallel to the length and / or width of the glass.

[0074] In S1, the spray parameters are first matched using software, and the offset is calculated using the following function:

[0075] [Zn1, Zm1]=FUNC_Z1{[Z, A], [P1, Q1, Φ1], [H1], [α1]}

[0076] [Xn1, Xm1]=FUNC_X1{[X, A], [P1, Q1, Φ1], [H1], [α1]},

[0077] Where Zn1 is the number of offsets in the height direction, Zm1 is the offset interval in the height direction, Z is the height of glass 1, A is the spray width, P1 is the spray negative pressure, Q1 is the spray flow rate, Φ1 is the particle size, H1 is the vertical distance between the atomizing nozzle 4 and the surface of glass 1, α1 is the tilt angle of the tool mounting base 7 during spraying, Xn1 is the number of offsets in the width direction, Xm1 is the offset interval in the width direction, and X is the width of glass 1.

[0078] The robot generates a spray path based on offset parameters in the height and width directions:

[0079] [Route1, V1]=FUNC_Route1{[Zn1, Zm1], [Xn1, Xm1]}

[0080] Where Route1 is the spray path and V1 is the spray speed;

[0081] In S2, the coating parameters are first matched using software, and the offset is calculated using the following function:

[0082] [Zn2, Zm2]=FUNC_Z2{[Z, B], [P2, Q2], [H2], [α2]};

[0083] [Xn2, Xm2]=FUNC_X2{[X, B], [P2, Q2], [H2], [α2]};

[0084] Where Zn2 is the number of offsets in the height direction, Zm2 is the offset interval in the height direction, Z is the height of glass 1, B is the coating width, P2 is the coating air pressure, Q2 is the air flow rate, H2 is the vertical distance between the air knife 5 and the surface of glass 1, α2 is the tilt angle of the tool mounting base 7 during coating; Xn2 is the number of offsets in the width direction, Xm2 is the offset interval in the width direction, and X is the width of glass 1.

[0085] The robot generates a coating path based on offset parameters in the height and width directions:

[0086] [Route2, V2]=FUNC_Route2{[Zn2, Zm2], [Xn2, Xm2]},

[0087] Where Route2 is the coating path and V2 is the coating speed;

[0088] In S3, the solidification parameters are first matched using software, and the offset is calculated using the following function:

[0089] [Zn3, Zm3]=FUNC_Z3{[Z, B], [P3, Q3], [H3], [α3]}

[0090] [Xn3, Xm3]=FUNC_X3{[X, B], [P3, Q3], [H3], [α3]}

[0091] Where Zn3 is the number of offsets in the height direction, Zm3 is the offset interval in the height direction, Z is the height of glass 1, B is the curing width, P3 is the hot air pressure, Q3 is the air flow rate, H3 is the vertical distance between the air jet and the surface of glass 1, α3 is the tilt angle of the tool mounting base 7 during curing; Xn3 is the number of offsets in the width direction, Xm3 is the offset interval in the width direction, and X is the width of glass 1.

[0092] The robot generates the curing path based on offset parameters in the height and width directions:

[0093] [Route3, V3]=FUNC_Route3{[Zn3, Zm3], [Xn3, Xm3]}

[0094] Where Route3 is the curing path and V3 is the curing speed.

[0095] H1, H2, and H3 are all perpendicular to glass 1. H1, H2, and H3 are set values, and the distances for spraying, coating, and curing are generally different, with spraying and curing typically being at a higher distance than coating. Preferably, H1 ≥ H3 > H2, and α2 > α3 ≥ α1.

[0096] It should be noted that the glass width X is the dimension of the glass in the direction of movement, and the glass height Z is the dimension of the glass in the height direction.

[0097] Spray width A is the size of the spraying tool, calculated based on the coverage area of ​​the nozzle.

[0098] The coating width B is the size of the air knife tool, which is directly measured from the air outlet width.

[0099] The curing width C is the size of the hot air tool, which is directly measured to determine the width of the air outlet.

[0100] Taking the spraying process as an example, such as Figures 5-8 The document lists four implementations, namely Examples 1-4, illustrating the glass spray path, planned according to the glass width X and height Z. Figure 8 In the path of Example 4, the spraying direction can be opposite to the movement direction of the glass, so that the movement distance of the robotic arm can be reduced by taking advantage of the movement direction of the glass.

[0101] The tilt angle of tool mount 7 is mainly due to the different glass sizes, especially the different heights Z, resulting in different tilt angles β. This can be calculated based on the production line's tilt angle γ and the glass height Z. Taking the spraying process as an example... Figure 9 and Figure 10 β1 can be calculated based on the tilt angle γ of the conveying equipment 2 and the height Z of the glass, α1 = 90° - β1. However, during coating, the angle of the air knife is generally set to be relatively large to facilitate the removal of excess liquid material (spraying nano-coating liquid or water, etc.) from the glass surface.

[0102] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
