The pressing plate is detachably connected to the pressing column and located below the pressing column, with the pressing plate positioned above the conveyor trough.

[0007] The pressure coating protection assembly further includes a cavity and a storage box. The cavity is fixedly connected to the conveyor table and located inside the conveyor table. The cavity is located below the conveyor trough, and the storage box is located inside the cavity.

[0008] The pressing coating protection component also includes a feed inlet, which is detachably connected to the storage box and located on one side of the storage box. The feed inlet is perpendicular to the storage box, and the end of the feed inlet away from the storage box is located on one side of the conveyor table.

[0009] The pressure coating protection assembly further includes a base frame and an application nozzle.

The moving groove is fixedly connected to the support plate and is located inside the support plate.

[0012] The acrylic sheet laminating assembly further includes a laminating machine, an extension column, and a laminating plate.

[0013] The present invention also provides a method for surface protection treatment of mesh fabric, applicable to the above-mentioned mesh fabric surface protection treatment device, comprising the following steps:

[0014] Place the mesh fabric to be processed flat on the conveyor table, and cover the upper surface of the mesh fabric with a suitable polyurethane film.

[0015] After the polyurethane film is covered on one side of the mesh, it is transported to the bottom of the pressing plate by the conveying groove. The drive motor is started to make the pressing column descend, thereby driving the pressing plate to press the polyurethane film and the mesh, ensuring that the special material is tightly attached to the mesh, and achieving effective protection of one side of the mesh.

[0016] After the pressing and protection are completed, the mesh is conveyed to the top of the application nozzle, the application nozzle is activated, and the NA paste is evenly applied to the lower side of the mesh to ensure that the NA paste evenly covers the lower surface of the mesh.

[0017] After the paste is applied, the acrylic sheet is placed on the placement rack. When the mesh is conveyed to the top of the placement rack, the pressing machine is started, causing the extension column and pressing plate to descend and press onto the mesh with appropriate pressure, so that the paste thickness exists only in two layers and within the mesh.

[0018] After the acrylic sheet is laminated, NA paste is left on the surface of the mesh to etch the steel wires at the mesh openings. The etching time is adjusted according to the material of the steel wire and the required wire diameter. After etching, the acrylic sheet is removed, and the residual paste on the surface of the mesh is cleaned to obtain the processed mesh.

[0019] After processing, staff will conduct a visual inspection and collect the netting by category.

[0020] After the mesh fabric is sorted and collected, it is fixed on the mesh frame according to the traditional screen preparation process, and covered with a polymer film to complete the screen preparation, thereby completing the protective treatment of the mesh fabric surface.

Due to the addition of the pressing coating protection component, the problem of the lack of effective surface protection measures for the screen fabric during the printing process in the traditional screen preparation and use process is effectively solved. The screen fabric is easily damaged, which affects the service life of the screen and the stability of the printing quality. Existing processing methods often cannot accurately control the etching process, resulting in uneven etching of the mesh. Attached Figure Description

Detailed Implementation

[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] First Embodiment

[0033] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of the first embodiment of the present invention. Figure 2 This is a side view of the entire first embodiment of the present invention. Figure 3 This is a top view of the entire first embodiment of the present invention.

[0034] This invention provides a screen fabric surface protection treatment device, including a pressing coating protection component. The pressing coating protection component includes a conveyor table 101, a conveyor trough 102, a side plate 103, a top plate 104, a drive motor 112, a pressing column 105, a pressing plate 106, a cavity 107, a storage box 108, a feed inlet 109, a base frame 110, and a coating nozzle 111. This solution addresses the problem that in traditional screen preparation and use, the screen fabric lacks effective surface protection measures during printing, making it susceptible to damage and affecting the screen's lifespan and the stability of printing quality. Existing processing methods often cannot precisely control the etching process, resulting in uneven mesh etching and affecting the passage and uniform distribution of printing silver paste. This leads to excessive consumption of printing silver paste, increasing manufacturing costs in the photovoltaic industry. Understandably, the aforementioned solution involves placing the mesh fabric to be treated flat on the conveyor table 101 during the mesh fabric surface protection treatment. A polyurethane film of appropriate size is then applied to the upper surface of the mesh fabric. The conveyor trough 102 is used to smoothly transport the mesh fabric, allowing it to pass smoothly through each processing stage. The side plate 103 provides support and protection, ensuring the stability of the mesh fabric during equipment operation. The top plate 104 provides a mounting base for components such as the drive motor 112 and the pressing column 105. The drive motor 112 serves as a power source, providing power for the up-and-down movement of the pressing column 105. After the polyurethane film is applied to the upper side of the mesh fabric, it is transported by the conveyor trough 102 to the area below the pressing plate 106. The drive motor 112 is then activated, causing the pressing column 105 to descend, thereby pressing the pressing plate 106 against the polyurethane film and the mesh fabric. By adjusting the operating parameters of the drive motor 112, the pressure and pressing time of the pressing plate 106 can be precisely controlled, ensuring a tight fit between the polyurethane film and the mesh fabric, effectively protecting one side of the mesh fabric. The storage box 108 is used to store NA paste and other coatings. NA paste can be easily added to the storage box 108 through the inlet 109. After the pressing and protection are completed, the mesh fabric is conveyed by the conveyor trough... The transmission of 102 reaches above the coating nozzle 111, activating the coating nozzle 111. NA paste is then transported from the storage tank 108 through a pipe to the coating nozzle 111 and evenly coated on the lower side of the screen fabric. This ensures that the NA paste evenly covers the lower surface of the screen fabric, effectively solving the problem that in traditional screen preparation and use, the screen fabric lacks effective surface protection measures during printing, making it susceptible to damage and affecting the screen's lifespan and the stability of printing quality. Existing processing methods often cannot precisely control the etching process, resulting in uneven mesh etching, affecting the passage and distribution uniformity of the printing silver paste, causing excessively high silver paste consumption, and increasing the manufacturing cost of the photovoltaic industry.

[0035] In this specific embodiment, the conveying groove 102 is fixedly connected to the conveying platform 101 and is located inside and above the conveying platform 101. The side plate 103 is detachably connected to the conveying platform 101 and is located above the conveying platform 101. The side plate 103 is disposed on one side of the conveying groove 102. The top plate 104 is detachably connected to the side plate 103 and is located above the side plate 103. The top plate 104 is disposed above the conveying groove 102. The driving motor... Machine 112 is detachably connected to the top plate 104 and is located above the top plate 104. Pressing column 105 passes through the top plate 104 and is detachably connected to the drive motor 112, located at the output end of the drive motor 112. Pressing column 105 is positioned above the conveying groove 102. Pressing plate 106 is detachably connected to the pressing column 105 and is located below the pressing column 105. Pressing plate 106 is positioned above the conveying groove 102. (This is for the purpose of mesh fabrication.) During surface protection treatment, the mesh fabric to be treated is first placed flat on the conveyor table 101. A polyurethane film of appropriate size is selected and covered on the upper surface of the mesh fabric. The conveyor trough 102 is used to smoothly transport the mesh fabric, allowing it to pass smoothly through each processing stage. The side plate 103 provides certain support and protection to ensure the stability of the mesh fabric during equipment operation. The top plate 104 provides a mounting base for components such as the drive motor 112 and the pressing column 105. The drive motor 112 serves as a power source, providing power for the up-and-down movement of the pressing column 105. After the polyurethane film covers the upper side of the mesh fabric, it is transported by the conveyor trough 102 to the area below the pressing plate 106. The drive motor 112 is then started, causing the pressing column 105 to descend, thereby driving the pressing plate 106 to press the polyurethane film and the mesh fabric together. By adjusting the operating parameters of the drive motor 112, the pressure and pressing time of the pressing plate 106 can be precisely controlled.

[0036] The cavity 107 is fixedly connected to the conveyor 101 and is located inside the conveyor 101. The cavity 107 is located below the conveyor trough 102, and the storage box 108 is located inside the cavity 107.

[0037] Secondly, the feed inlet 109 is detachably connected to the storage box 108 and is located on one side of the storage box 108. The feed inlet 109 is perpendicular to the storage box 108. The end of the feed inlet 109 away from the storage box 108 is located on one side of the conveyor table 101. The storage box 108 is used to store NA paste and other coatings. NA paste can be conveniently added to the storage box 108 through the feed inlet 109.

[0038] Simultaneously, the base frame 110 is detachably connected to the storage tank 108 and is located above the storage tank 108. The base frame 110 is disposed inside the lower part of the transfer channel 102. The application nozzle 111 is detachably connected to the base frame 110 and is located above the base frame 110. The application nozzle 111 is disposed inside the transfer channel 102. The mesh fabric is transported by the transfer channel 102 to the top of the application nozzle 111. The application nozzle 111 is activated, and NA paste is transported from the storage tank 108 to the application nozzle 111 through a pipe. Then, it is evenly applied to the lower side of the mesh fabric to ensure that the NA paste evenly covers the lower surface of the mesh fabric.

[0039] When using this invention for surface protection treatment of mesh fabric, the mesh fabric to be treated is first placed flat on the conveyor table 101. A polyurethane film of appropriate size is selected and covered on the upper surface of the mesh fabric. The conveyor trough 102 is used to smoothly transport the mesh fabric, allowing it to pass smoothly through each processing stage. The side plate 103 provides certain support and protection to ensure the stability of the mesh fabric during equipment operation. The top plate 104 provides a mounting base for components such as the drive motor 112 and the pressing column 105. The drive motor 112 serves as a power source, providing power for the up-and-down movement of the pressing column 105. After the polyurethane film covers the upper side of the mesh fabric, it is transported by the conveyor trough 102 to the area below the pressing plate 106. The drive motor 112 is then started, and the drive motor 112 drives... The pressing column 105 descends, thereby driving the pressing plate 106 to press the polyurethane film and the mesh fabric together. By adjusting the operating parameters of the drive motor 112, the pressure and pressing time of the pressing plate 106 can be precisely controlled to ensure that the polyurethane film and the mesh fabric are tightly bonded, achieving effective protection of one side of the mesh fabric. The storage box 108 is used to store coatings such as NA paste. NA paste can be conveniently replenished into the storage box 108 through the feed port 109. After the pressing and protection are completed, the mesh fabric is transported by the conveying groove 102 to the top of the application nozzle 111. The application nozzle 111 is activated, and NA paste is transported from the storage box 108 to the application nozzle 111 through the pipeline, and then evenly applied to the lower side of the mesh fabric, ensuring that the NA paste evenly covers the lower surface of the mesh fabric.

The pressing machine 206 moves along the moving trough 205, causing the extension column 207 and the pressing plate 208 to descend and press onto the mesh fabric with appropriate pressure, so that the paste thickness exists only in two layers and within the mesh. By adjusting the operating parameters of the pressing machine 206, the pressure and downward position of the pressing plate 208 can be precisely controlled to ensure that the paste thickness meets the requirements.

[0046] When using this invention, after the paste is applied, an acrylic plate of appropriate size is placed on the placement rack 202.

The low railing 303 is also provided with... After the acrylic sheet is pressed onto one side of the guardrail 302, NA paste is allowed to remain on the surface of the mesh for a certain period of time, allowing the paste to etch the steel wires at the mesh openings. The etching time is adjusted according to the material of the steel wire and the required wire diameter. After etching, the acrylic sheet is removed, and the residual paste on the surface of the mesh is cleaned to obtain the processed mesh. The processed mesh is then transferred to the placement platform 301 for visual inspection by the staff. The guardrail 302 and the low railing 303 provide a certain degree of protection to prevent the mesh from falling off when it moves on the placement platform.

[0052] The placement cavity 304 is fixedly connected to the placement platform 301 and is located below the placement platform 301.

[0053] Secondly, the waste bin 305 is detachably connected to the placement platform 301 and is located inside the placement platform 301.

Mesh fabric that meets the quality requirements is placed in the collection bin 306, and mesh fabric that does not meet the quality requirements is placed in the waste bin 305. After the mesh fabric is sorted and collected, according to the traditional screen printing process, the mesh fabric in the collection bin 306 is fixed on the screen frame and covered with a polymer film to complete the screen printing process, thereby completing the protective treatment of the mesh fabric surface.

[0054] In using this invention, the guardrail 302 and the low railing 303 provide a certain degree of protection, preventing the mesh fabric from falling off when it moves on the placement platform. After the acrylic plate is pressed, NA paste is allowed to remain on the surface of the mesh fabric for a certain period of time, allowing the paste to etch the steel wires at the mesh openings. The etching time is adjusted according to the material of the steel wire and the required wire diameter. After etching, the acrylic plate is removed, and the residual paste on the surface of the mesh fabric is cleaned to obtain the treated mesh fabric. The treated mesh fabric is then transferred to the placement platform 301 for visual inspection by staff. Mesh fabrics that meet the quality requirements are placed in the collection box 306, while those that do not meet the quality requirements are placed in the waste bin 305. After the mesh fabrics are sorted and collected, they are fixed to the mesh frame in the collection box 306 according to the traditional screen preparation process, and covered with a polymer film to complete the screen preparation, thereby completing the protective treatment of the mesh fabric surface.

[0055] The present invention also provides a method for surface protection treatment of mesh fabric, applicable to the above-described mesh fabric surface protection treatment device;

[0056] Please see Figure 7 , Figure 7 This is a schematic diagram illustrating the operating principle of the method for surface protection treatment of mesh fabric according to the present invention.

[0057] Place the mesh fabric to be processed flat on the conveyor table 101, and select a suitable polyurethane film to cover the upper surface of the mesh fabric.

[0058] After the polyurethane film is covered on the upper side of the mesh, it is transported by the conveying groove 102 to the lower part of the pressing plate 106. The drive motor 112 is started to lower the pressing column 105, thereby driving the pressing plate 106 to press the polyurethane film and the mesh, ensuring that the special material is tightly attached to the mesh, and achieving effective protection of one side of the mesh.

[0059] After the pressing and protection are completed, the mesh is conveyed to the top of the application nozzle 111, the application nozzle 111 is activated, and the NA paste is evenly applied to the lower side of the mesh to ensure that the NA paste evenly covers the lower surface of the mesh.

[0060] After the paste is applied, the acrylic plate is placed on the placement rack 202. When the mesh is conveyed above the placement rack 202, the pressing machine 206 is started, causing the extension column 207 and the pressing plate 208 to descend and press onto the mesh with appropriate pressure, so that the paste thickness exists only in two layers and in the mesh.

[0061] After the acrylic sheet is laminated, NA paste is left on the surface of the mesh to etch the steel wires at the mesh openings. The etching time is adjusted according to the material of the steel wire and the required wire diameter.
