Description

Technical Field

[0001] This utility model relates to the field of power generation glass technology, and in particular to a power generation glass thin film coating mechanism. Background Technology

[0002] A photovoltaic glass thin film coating mechanism refers to a device or system specifically designed for uniformly coating photoelectric conversion materials (such as perovskite, CIGS, CdTe, etc.) onto glass substrates or other suitable transparent or translucent substrates. This mechanism is one of the key pieces of equipment in the manufacture of solar panels and other optoelectronic devices. It aims to ensure the generation of high-quality functional layers through a precisely controlled coating process to achieve high energy conversion efficiency.

[0003] In existing technologies, some photovoltaic glass film coating mechanisms only have basic coating functions and lack efficient cleaning and protection designs for the substrate surface. Typically, these devices do not integrate effective dust removal and static electricity elimination units before coating, resulting in the inability to remove tiny particles, dust, or electrostatic adsorption substances generated during the transportation process from the surface of the photovoltaic glass film in a timely manner. In actual operation, operators often need to rely on manual wiping or offline cleaning methods to pre-treat the substrate, which is not only inefficient but also makes it difficult to ensure the uniformity and thoroughness of cleaning. In addition, due to the lack of a dynamic dust collection and static electricity elimination synergistic mechanism, loosened contaminants are easy to re-adhere to the film surface before coating, thereby forming pinholes, agglomerates, or interface defects in the subsequent coating process, which seriously affects the uniformity, adhesion, and photoelectric conversion performance of the film.

[0004] To address the existing problems, there is a need to provide a coating mechanism for power-generating glass films with a cleaning function. Utility Model Content

[0005] To overcome the shortcomings of not being able to efficiently clean and protect the surface of the substrate, this utility model provides a coating mechanism for a power generation glass film.

[0006] The technical solution of this utility model is as follows: a coating mechanism for a photovoltaic glass film, comprising a coating machine, a connecting frame, a partition, an industrial vacuum cleaner, vacuum pipes, a vacuum frame, an electrostatic bar, a mounting plate, a mounting block, a first motor, a non-woven wiping wheel, a first connecting block, a cleaning frame, a connecting plate, a fixing rod, and a spring. The front side of the coating machine is connected to the connecting frame, and a partition is installed inside the connecting frame. The industrial vacuum cleaner is installed inside the connecting frame, and vacuum pipes are symmetrically connected to the left and right sides of the industrial vacuum cleaner. A vacuum frame is installed inside the connecting frame, and the other ends of both vacuum pipes are connected to the vacuum frame. An electrostatic bar is installed on the partition, and a mounting plate is placed on the connecting frame. A mounting plate is provided, on which mounting blocks are symmetrically slidably connected. A first motor is connected to the mounting block on the left. A non-woven fabric wiping wheel is rotatably connected between the two mounting blocks. The output shaft of the first motor passes through the mounting block and is connected to the non-woven fabric wiping wheel. A first connecting block is connected to each of the two mounting blocks. A cleaning frame is connected between the two first connecting blocks. The cleaning frame contacts and engages with the non-woven fabric wiping wheel. Connecting plates are symmetrically connected to the mounting plate on the left and right. Fixing rods are slidably connected inside each of the two connecting plates. The two fixing rods engage with the corresponding mounting blocks. Springs are connected between the two fixing rods and the corresponding connecting plates.

[0007] Furthermore, it also includes a lifting plate, a mounting frame, a lead screw, a guide rod, and a second motor. The lifting plate is connected to the mounting plate, the mounting frame is installed on the connecting frame, the lead screw is rotatably connected inside the mounting frame, the guide rod is connected inside the mounting frame, and the second motor is installed on the mounting frame. The output shaft of the second motor passes through the mounting frame and is connected to the lead screw.

[0008] Furthermore, it also includes a protective shell, which is installed on the mounting bracket.

[0009] Furthermore, it also includes a pull rod, with pull rods connected to both fixed rods.

[0010] Furthermore, the surface of the nonwoven wiping wheel is covered with microfiber dust-free cloth.

[0011] Furthermore, the coating machine has multiple mounting holes.

[0012] The beneficial effects of this utility model are as follows: By integrating non-woven fabric wiping, static elimination, dynamic dust collection, and automatic coating functions, it achieves efficient online removal of contaminants on the substrate surface, effectively avoiding coating defects such as pinholes, agglomeration, and delamination caused by dust and electrostatic adsorption. It significantly improves the uniformity, density, adhesion, and photoelectric conversion performance of the film. This structure realizes integrated continuous operation of "cleaning-static elimination-dust removal-coating", greatly reducing the dependence on manual pretreatment and improving the level of production automation and process repeatability. Through the synergistic effect of the electrostatic bar and the dust collection frame, a dual protection mechanism of "neutralization + capture" is formed to prevent the secondary adhesion of loose particles and ensure that the substrate is always in a high cleanliness state before entering the coating area.

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0021] Example: A thin film coating mechanism for power-generating glass, such as Figures 1-6As shown, the system includes a coating machine 1, a connecting frame 2, a partition 201, an industrial vacuum cleaner 3, a vacuum hose 4, a vacuum frame 5, an electrostatic bar 6, a mounting plate 7, a mounting block 8, a first motor 9, a non-woven fabric wiping wheel 10, a first connecting block 11, a cleaning frame 12, a connecting plate 13, a fixing rod 14, a spring 15, a lifting plate 16, a mounting bracket 17, a lead screw 18, a guide rod 19, a second motor 20, a protective shell 21, and a pulling rod 22. The coating machine 1 has multiple mounting holes for easy installation. The front side of the coating machine 1 is connected to the connecting frame 2, which houses the partition 201. The industrial vacuum cleaner 3 is installed inside the connecting frame 2, providing a negative pressure airflow power source. Dust pipe 4 removes dust and suspended particles generated during the cleaning process, preventing environmental pollution or re-adhesion to the substrate surface and ensuring a clean working environment. The industrial vacuum cleaner 3 is symmetrically connected with suction pipes 4 on both sides. A suction frame 5 is installed inside the connecting frame 2, and the other ends of both suction pipes 4 are connected to the suction frame 5. An electrostatic bar 6 is installed on the partition 201, which releases positive and negative ions after being energized, neutralizing the static charge generated on the surface of the power-generating glass film due to friction, eliminating the electrostatic adsorption effect, preventing secondary dust adhesion, and improving cleaning and coating quality. An installation plate 7 is placed on the connecting frame 2, and installation blocks 8 are symmetrically slidably connected to the installation plate 7 on both sides. A first motor 9 is connected to the left installation block 8. Between the two installation blocks 8... A non-woven wiping wheel 10 is rotatably connected. The surface of the non-woven wiping wheel 10 is covered with a microfiber lint-free cloth, which makes slight contact with the surface of the power generation glass film. During rotation, it physically adsorbs particulate impurities such as dust and oil, achieving preliminary cleaning of the substrate surface. The output shaft of the first motor 9 passes through the mounting block 8 and is connected to the non-woven wiping wheel 10. Each of the two mounting blocks 8 is connected to a first connecting block 11, and a cleaning frame 12 is connected between the two first connecting blocks 11. The cleaning frame 12 contacts and engages with the non-woven wiping wheel 10, scraping off the dust and impurities adhering to its surface, preventing the accumulation of contaminants from affecting the cleaning effect, and extending the service life of the lint-free cloth. The mounting plate 7 is positioned on the left and right sides. The system is symmetrically connected by connecting plates 13, with fixed rods 14 slidably connected inside each connecting plate 13. The two fixed rods 14 engage with the corresponding mounting blocks 8. Springs 15 connect the two fixed rods 14 to the corresponding connecting plates 13. A lifting plate 16 is connected to the mounting plate 7. A mounting frame 17 is mounted on the connecting frame 2. A lead screw 18 is rotatably connected inside the mounting frame 17. A guide rod 19 is connected inside the mounting frame 17. A second motor 20 is mounted on the mounting frame 17. The output shaft of the second motor 20 passes through the mounting frame 17 and connects to the lead screw 18. A protective shell 21 is mounted on the mounting frame 17 to protect the second motor 20. Pull rods 22 are connected to both fixed rods 14.

[0022] When this device is needed, the operator first installs the power-generating glass film coating machine 1 at the preset station of the coating production line, ensuring that it is aligned and securely connected with the front and rear conveyor rollers, the coating host, and other auxiliary equipment. After the entire machine is installed and debugged, it can be started. During operation, the power-generating glass film enters from the front of the device through the conveying system, passing through the cleaning unit, the static elimination unit, and the coating unit in sequence. When the power-generating glass film is conveyed to the bottom of the device, the operator starts the first motor 9, the industrial vacuum cleaner 3, the static bar 6, and the coating machine 1. The output shaft of the first motor 9 drives the non-woven cloth wiping wheel 10 to rotate. The rotating non-woven cloth wiping wheel 10 makes slight contact with the surface of the glass film, utilizing the highly absorbent dust-free cloth covering its surface. The nonwoven wiping roller 10 effectively adheres to and removes particulate contaminants such as dust and fibers from the substrate surface, achieving physical wiping cleaning. During the continuous rotation of the nonwoven wiping roller 10, its outer periphery contacts and engages with the fixed cleaning frame 12. The cleaning frame 12 scrapes or brushes off accumulated dust and impurities adhering to the nonwoven surface, preventing secondary transfer of contaminants and ensuring the wiping roller maintains its cleaning efficiency over a long period. The wiped photovoltaic glass film continues to be conveyed forward into the action area of ​​the electrostatic bar 6. The electrostatic bar 6 releases positive and negative ions, neutralizing the static charge generated on the substrate surface due to friction, eliminating the electrostatic adsorption effect, and preventing dust from re-adhering in subsequent processes. Simultaneously, the industrial vacuum cleaner 3 is activated, introducing airflow into the vacuum frame 5 through symmetrically arranged vacuum pipes 4 on both sides. The vacuum frame 5 is located above the substrate and is equipped with… The rectangular suction port creates a localized negative pressure zone, efficiently capturing suspended particles that have been loosened or released due to static electricity during wiping, preventing them from re-settling onto the clean surface. This achieves simultaneous cleaning and suction, enabling coordinated dust removal. After cleaning and static elimination, the photovoltaic glass film is smoothly conveyed to the bottom of the coating machine 1, where it is evenly coated by the coating rollers inside the machine. The coating rollers maintain a constant gap with the film surface to ensure consistent thickness and no defects in the functional layers (such as perovskite precursors and electron transport layers). After coating, the film continues to be conveyed to the next stage, entering the drying, curing, or subsequent processing stations, thus completing a full coating process. When the non-woven wiping roller 10 becomes saturated with adsorption or wears down after a period of use, affecting the cleaning effect, it needs to be replaced. At this time, the staff... The second motor 20 is started, and its output shaft drives the lead screw 18 to rotate. The lead screw 18 engages with the nut on the lifting plate 16, driving the lifting plate 16 to rise smoothly along the guide rod 19. The lifting plate 16 drives the mounting plate 7, mounting block 8, non-woven wiping wheel 10, and other components mounted on it to move upward as a whole, leaving the working position and providing sufficient space for replacement operations. Then, the operator pulls the pull rods 22 on both sides with both hands, causing the fixing rod 14 to move inward against the elastic force of the spring 15, so that it disengages from the slot of the mounting block 8, releasing the limitation on the mounting block 8. At this time, the two mounting blocks 8 can slide on the mounting plate 7, making it easy to remove the old non-woven wiping wheel 10 assembly as a whole. After replacing the new assembly, the new mounting block 8 is slid into the guide rail of the mounting plate 7, and the pull rods 22 are released.Spring 15 returns to its original deformation, pushing the fixing rod 14 to automatically reset and re-lock the mounting block 8, achieving rapid locking. Finally, the second motor 20 is started in reverse, and the lead screw 18 drives the lifting plate 16 down along the guide rod 19 to the initial working position. The motor is then turned off, and the equipment returns to normal operation, ready to resume production.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
