Detailed implementation manners

[0031] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] First embodiment

[0033] Please refer to Figures 1 to 3 , Figure 1 which is the overall structural schematic diagram of the first embodiment of the present invention, Figure 2 which is the overall side view of the first embodiment of the present invention, Figure 3 which is the overall top view of the first embodiment of the present invention.

[0034] The present invention provides a device for surface protection treatment of mesh cloth, including a pressing and coating protection component. The pressing and coating protection component includes a conveying table 101, a conveying groove 102, side plates 103, a top plate 104, a driving motor 112, a pressing column 105, a pressing plate 106, a cavity 107, a storage tank 108, a feeding port 109, a base frame 110, and a coating spray head 111. Through the foregoing solution, in the traditional process of screen plate preparation and use, during the printing process of the mesh cloth, there is a lack of effective surface protection measures, and it is easily damaged, thereby affecting the service life of the screen plate and the stability of printing quality. Existing treatment methods often cannot accurately control the etching process, resulting in uneven etching of the mesh holes, affecting the passing performance and uniform distribution of the printing silver paste, causing too high a single consumption of the printing silver paste, and increasing the manufacturing cost of the photovoltaic industry. It can be understood that in the foregoing solution, when performing surface protection treatment on the mesh cloth, first place the mesh cloth to be treated flat on the conveying table 101, select a polyurethane film of appropriate size and cover it on the upper surface of the mesh cloth. The conveying groove 102 is used to smoothly convey the mesh cloth so that it can pass through each treatment link smoothly. The side plates 103 play a certain supporting and protective role to ensure the stability of the mesh cloth during the operation of the equipment. The top plate 104 provides an installation basis for components such as the driving motor 112 and the pressing column 105. The driving motor 112 serves as a power source to provide power for the up and down movement of the pressing column 105. When the polyurethane film covers one side above the mesh cloth, it is conveyed by the conveying groove 102 to the lower part of the pressing plate 106. Start the driving motor 112, and the driving motor 112 drives the pressing column 105 to descend, thereby driving the pressing plate 106 to press the polyurethane film and the mesh cloth. By adjusting the operating parameters of the driving motor 112, the pressure and pressing time of the pressing plate 106 can be accurately controlled to ensure that the polyurethane film is tightly attached to the mesh cloth, realizing effective protection of one side of the mesh cloth. The storage tank 108 is used to store coatings such as NA paste. The NA paste can be conveniently replenished into the storage tank 108 through the feeding port 109. After the pressing protection is completed, the mesh cloth reaches above the coating spray head 111 with the conveyance of the conveying groove 102. Start the coating spray head 111, and the NA paste is conveyed from the storage tank 108 to the coating spray head 111 through a pipeline and then evenly coated on the lower side of the mesh cloth to ensure that the NA paste evenly covers the lower surface of the mesh cloth. Thus, it effectively solves the problems in the traditional process of screen plate preparation and use, that is, during the printing process of the mesh cloth, there is a lack of effective surface protection measures, it is easily damaged, thereby affecting the service life of the screen plate and the stability of printing quality. Existing treatment methods often cannot accurately control the etching process, resulting in uneven etching of the mesh holes, affecting the passing performance and uniform distribution of the printing silver paste, causing too high a single consumption of the printing silver paste, and increasing the manufacturing cost of the photovoltaic industry.

The mesh fabric reaches above the coating spray head 111 along with the transfer of the transfer groove 102. The coating spray head 111 is activated, and the NA paste is transported from the storage box 108 to the coating spray head 111 through a pipeline, and then 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 the present invention for surface protection treatment of the mesh fabric, first, the mesh fabric to be treated is placed flat on the transfer table 101, and a polyurethane film of a suitable size is covered on the upper surface of the mesh fabric. The transfer groove 102 is used to stably transfer the mesh fabric so that it can smoothly pass through each processing link. The side plate 103 plays a certain supporting and protecting role to ensure the stability of the mesh fabric during the operation of the equipment. The top plate 104 provides an installation foundation for components such as the drive motor 112 and the pressing column 105. The drive motor 112 serves as a power source to provide power for the up and down movement of the pressing column 105. After the polyurethane film covers one side above the mesh fabric, it is transferred by the transfer groove 102 to below the pressing plate 106. The drive motor 112 is activated, and the drive motor 112 drives the pressing column 105 to descend, thereby driving the pressing plate 106 to press 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 to ensure that the polyurethane film is closely attached to the mesh fabric, achieving effective protection of one side of the mesh fabric. The storage box 108 is used to store coatings such as NA paste, and the NA paste can be conveniently replenished into the storage box 108 through the feeding port 109. After the pressing protection is completed, the mesh fabric reaches above the coating spray head 111 along with the transfer of the transfer groove 102.
