Description

Technical Field

[0001] This application relates to the field of glass transmission technology, and in particular to a glass transmission structure for photovoltaic modules. Background Technology

[0002] This equipment, used for transporting photovoltaic (PV) glass substrates and as a testing platform, is applied to the automated assembly and testing of tempered glass in PV modules. With the development of the industry and advancements in glass technology, the thickness of surface PV module glass is becoming increasingly thinner, placing higher demands on the stability and integrity of its transport process. Compared to previous PV glass transport methods, this process is more prone to structural damage, unstable, and subject to wear, dust generation, and vibration, resulting in a higher scrap rate during the PV glass production and assembly stage.

[0003] The utility model patent with application number "202121529379.7" and patent name "an air-floating transmission platform for photovoltaic glass coating" and publication date "2021.12.28" discloses an air-floating transmission platform. However, with the increasingly thin photovoltaic glass, the damage rate during transmission is relatively high.

[0004] Therefore, there is an urgent need for a photovoltaic module glass transmission structure to improve the stability of photovoltaic glass transmission, reduce the scrap rate of photovoltaic glass during transmission, and lower the production and assembly costs for enterprises. Utility Model Content

[0005] One of the technical problems this application aims to solve is: addressing the issue that existing photovoltaic glass transmission platforms are prone to damaging photovoltaic glass during transmission.

[0006] To address the aforementioned technical problems, embodiments of this application provide a photovoltaic module glass transmission structure, including an air-floating plate;

[0007] The air flotation plate has multiple receiving holes, and a drive wheel is rotatably installed in each receiving hole. The rolling direction of the drive wheel is parallel to the transmission direction; the upper edge of the drive wheel is higher than the upper edge of the air flotation plate.

[0008] The air flotation plate has multiple air holes running through its top and bottom; the air holes cover the entire cross-section of the air flotation plate; the air holes include negative pressure air holes and positive pressure air holes, of which the air holes distributed around the receiving hole are negative pressure air holes, and the remaining air holes are positive pressure air holes.

[0009] In some embodiments, the plurality of receiving holes are arranged in multiple rows and columns.

[0010] In some embodiments, at least two receiving holes are included in the same row, and the line connecting the centers of the receiving holes in the same row is parallel to the transmission direction.

[0011] In some embodiments, at least two receiving holes are included in the same column, and the line connecting the centers of the receiving holes in the same column is perpendicular to the transmission direction.

[0012] In some embodiments, each column of receiving holes includes the same number of receiving holes, and each row of receiving holes also includes the same number of receiving holes.

[0013] In some embodiments, the negative pressure vents are evenly arranged in the area where the longitudinal direction of the same row of receiving holes is directly opposite.

[0014] In some embodiments, positive pressure vents are evenly arranged between the areas where each row of receiving vents is longitudinally aligned.

[0015] In some embodiments, the spacing between two adjacent columns of receiving holes is less than the length of the photovoltaic glass, and the spacing between two adjacent rows of receiving holes is less than the width of the photovoltaic glass.

[0016] In some embodiments, the drive wheel is made of antistatic silicone rubber.

[0017] Through the above technical solution, this application provides a photovoltaic module glass transmission structure that transmits photovoltaic glass above an air-float plate via a rotating drive wheel. Negative pressure air holes are arranged around the drive wheel to draw in downward airflow, increasing the adhesion between the photovoltaic glass and the drive wheel. The increased contact area between the drive wheel and the photovoltaic glass due to compression enhances the static friction between them, preventing deviation of the photovoltaic glass in other directions during transmission due to external forces or inertia. Compared to traditional methods, this method saves on guiding devices. Simultaneously, positive pressure air holes are arranged at other locations on the air-float plate to allow upward-blowing airflow, forming an air film between the photovoltaic glass and the air-float plate. This reduces resistance during transmission due to the photovoltaic glass's own weight, resulting in faster transmission speeds, and also prevents friction between the photovoltaic glass and the air-float plate, reducing the risk of damage.

[0030] like Figures 1-2As shown, a photovoltaic module glass transport structure includes an air-float plate 1, which serves as the supporting part of the entire structure. Multiple receiving holes 2 are formed on the air-float plate 1, and a drive wheel 3 is rotatably installed in each receiving hole 2. The drive wheel 3 is driven by a motor to rotate. The rolling direction of the drive wheel 3 is parallel to the transport direction, and the upper edge of the drive wheel 3 is higher than the upper edge of the air-float plate 1. In use, the photovoltaic glass is placed above the drive wheel 3 of the air-float plate 1. Because the upper edge of the drive wheel 3 is higher than the upper edge of the air-float plate 1, the photovoltaic glass is pressed against the drive wheel 3, and the photovoltaic glass is transported by the static friction between the drive wheel 3 and the photovoltaic glass. Multiple air holes 4 are formed vertically through the air-float plate 1, covering the entire cross-section of the air-float plate 1. The air holes 4 include negative pressure air holes 401 and positive pressure air holes 402, used to provide positive or negative pressure for use during the photovoltaic glass transport process. In this embodiment, to avoid vibration or positive pressure air blowing during the transmission of the photovoltaic glass, the air holes 4 distributed around the receiving hole 2 are set as negative pressure air holes 401, drawing in air downwards and generating suction to pull the photovoltaic glass towards the air flotation plate 1. This creates a negative pressure airflow near the power wheel 3, increasing the adhesion between the photovoltaic glass and the power wheel 3. This force is the attraction caused by the negative pressure. The contact surface between the power wheel 3 and the photovoltaic glass increases due to compression, increasing the static friction between them. This prevents the photovoltaic glass from deviating in other directions during transmission due to external forces or inertia, saving on guiding devices compared to traditional methods. Furthermore, the air holes 4 at other locations on the air flotation plate 1 are set as positive pressure air holes 402, allowing upward-blown airflow to enter, creating a positive pressure area between the power wheels 3. This forms an air film between the photovoltaic glass and the air flotation plate 1, reducing the resistance during transmission caused by the photovoltaic glass's own weight, resulting in faster transmission speed. It also avoids friction between the photovoltaic glass and the air flotation plate 1, reducing the risk of damage.

[0031] In other specific embodiments, in addition to the above-mentioned technical features, to make the photovoltaic glass transmission process more stable, the multiple receiving holes 2 are arranged in multiple rows and columns. Each row includes at least two receiving holes 2, and the line connecting the centers of all receiving holes 2 in the same row is parallel to the transmission direction. Each column includes at least two receiving holes 2, and the line connecting the centers of all receiving holes 2 in the same column is perpendicular to the transmission direction. Each column and each row contains the same number of receiving holes 2. Since each receiving hole 2 is equipped with a drive wheel 3, a neatly arranged, aligned drive wheel 3 is formed, resulting in balanced force distribution and reduced skewness when the drive wheel 3 rotates to transmit the photovoltaic glass. This application provides a specific embodiment where the receiving holes 2 are arranged in two rows and two columns, with two receiving holes 2 in each row and two receiving holes 2 in each column.

[0032] To more accurately define the arrangement positions of the negative pressure vents 401 and positive pressure vents 402, further details are provided in some specific embodiments. In addition to the aforementioned technical features, in this specific embodiment, the negative pressure vents 401 are uniformly arranged within the longitudinally opposite area of ​​the same row of receiving holes 2. That is, the negative pressure vents 401 are positioned within the longitudinally opposite area of ​​each row of receiving holes 2, ensuring that the suction force generated by the negative pressure vents 401 on the photovoltaic glass is directly above the power wheel 3. This position, supported by the power wheel 3, prevents the photovoltaic glass from bending or deforming downwards. The positive pressure vents 402 are uniformly arranged between the longitudinally opposite areas of each row of receiving holes 2. That is, excluding the longitudinally opposite areas of each row of receiving holes 2 on the air-float plate 1, the uniform arrangement of the positive pressure vents 402 provides an upward thrust to the photovoltaic glass. This reduces the resistance during transmission caused by the photovoltaic glass's own weight, resulting in faster transmission speed. Furthermore, it avoids friction between the photovoltaic glass and the air-float plate 1, reducing the risk of damage.

[0033] To ensure the stability of transmission, the photovoltaic glass has at least two rows and two columns of drive wheels 3 under it. The spacing between two adjacent columns of receiving holes 2 is less than the length of the photovoltaic glass, and the spacing between two adjacent rows of receiving holes 2 is less than the width of the photovoltaic glass.

[0034] In addition, the power wheel 3 is made of anti-static silicone rubber, which increases the static friction between it and the photovoltaic glass and prevents scratches on the photovoltaic glass.

[0035] The embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described.
