Description

Technical Field

[0001] This utility model relates to the field of glass coating technology, specifically to an adaptive photovoltaic glass coating machine. Background Technology

[0002] Photovoltaic glass is the core encapsulation material for solar photovoltaic modules. It is mainly divided into two categories: crystalline silicon photovoltaic glass (including monocrystalline silicon and polycrystalline silicon) and thin-film photovoltaic glass. Its mainstream products include ultra-white rolled glass and AR coated glass, which need to have high light transmittance and weather resistance to protect photovoltaic cells.

[0003] AR coated glass, also known as anti-reflective glass or anti-transmittance glass, is a type of glass with a specially treated surface. It has a peak visible light transmittance of 99% and an average visible light transmittance of over 95%, which significantly improves the original brightness of LCDs and PDPs and reduces energy consumption. It is mainly used in solar cell modules, solar thermal, building, and automotive glass.

[0004] In the coating process of photovoltaic glass, the coating solution is mostly applied to the surface of the glass plate by a roller coating machine, and then the coating process is completed by heating, curing and cooling.

[0005] In the large-scale production of photovoltaic glass coating, traditional photovoltaic glass coating machines lack an effective and stable feeding structure, relying solely on the natural conveyor belt for transport. Without an active centering structure, the glass plates are prone to deviating from the centerline due to placement deviations or conveyor belt vibrations, resulting in problems such as poor centering accuracy and insufficient coating uniformity. This makes it difficult to meet the stringent requirements of modern photovoltaic glass for transmittance and film thickness consistency.

[0006] Therefore, this application proposes a novel adaptive photovoltaic glass coating machine. Utility Model Content

[0007] To address the technical problems existing in the background art, this utility model proposes an adaptive photovoltaic glass coating machine.

[0008] The adaptive photovoltaic glass coating machine proposed in this utility model includes a worktable, a coating machine body, and a conveyor belt. The coating machine body is suspended on the worktable. The conveyor belt passes through the coating machine body and is located below the coating roller. Fixed plates are installed on both sides of the feed end of the conveyor belt on the worktable. Stabilizers are provided on the opposite sides of the two fixed plates and are parallel to them. The stabilizers are connected to the fixed plates through multiple adjustable spacing components, and a stable channel for the glass plate to pass through is formed between the two stabilizers. The stable channel is aligned with the center line of the coating machine body and its width is adjustable.

[0009] As a further optimization of this utility model, the adjustment assembly includes a threaded rod for connecting the fixed plate and the stabilizer. The end of the threaded rod away from the stabilizer slides through to the outside of the fixed plate and is locked by a nut. A spring connected between the fixed plate and the stabilizer is fitted on the threaded rod.

[0010] As a further optimization of this utility model, the fixing plate has a sleeve hole adapted to the threaded rod, the end of the threaded rod away from the stabilizer is slidably sleeved with the sleeve hole, the nut is threadedly connected to the threaded rod and the pressure cap covers the outer opening of the sleeve hole.

[0011] As a further optimization of this utility model, multiple adjustment components are evenly distributed along the length of the fixed plate. A limiting plate located between two adjacent adjustment components is installed on the side of the fixed plate near the stabilizer. The free end of the limiting plate extends toward the stabilizer. The upper end of the stabilizer is provided with a movable hole that is adapted to and passes through the limiting plate. The limiting plate and the movable hole are slidably assembled.

[0012] As a further optimized solution of this utility model, the stabilizer includes a stabilizing block disposed above the conveyor belt and connected to the pitch adjustment component. The stabilizing block is L-shaped, with a first roller corresponding to and rollingly connected to the side of the glass plate on the short inner corner of the L-shape, and a second roller corresponding to and rollingly connected to the upper surface of the glass plate on the long inner corner of the L-shape.

[0013] As a further optimization of this utility model, a chute is provided on one side of the upper end face of the workbench, located outside the feed end opening of the conveyor belt. Both ends of the chute are slidably fitted with sliders located on the upper end face of the workbench, and the sliders are connected to the adjacent stabilizers through connecting rods.

[0014] As a further optimization of this utility model, guide rollers are installed on the opposite surfaces of the two sliders. The outer circumferential surface of the guide rollers is in rolling connection with the side of the glass plate, and the axis of the guide rollers is perpendicular to the conveying direction of the conveyor belt.

[0015] As a further optimization of this utility model, at least one slider is equipped with a handle for manual opening during glass plate feeding.

[0016] The adaptive photovoltaic glass coating machine proposed in this invention has the following beneficial effects: (i) A precise alignment system is constructed by using a "fixed plate + symmetrical stabilizer + adjustable spacing component". The two stabilizers are symmetrically distributed along the feed end of the conveyor belt to form a stable channel aligned with the center line of the coating machine body. The channel width can be flexibly adjusted by the adjustable spacing component. After the glass plate enters the channel, the stabilizer can actively guide it back to the conveyor center line, reduce the alignment error, and ensure that the glass plate and the coating roller are precisely connected, thereby reducing the uniformity of the coating thickness, improving the visible light transmittance of photovoltaic glass, and meeting the stringent requirements of solar cell modules for encapsulation materials. (ii) The spring of the adjustment component provides elastic preload for the stabilizer. When there are slight dimensional deviations or uneven surfaces in the glass plate, the stabilizer can adaptively fine-tune to avoid rigid compression that could cause damage to the glass edge. The limiting plate slides with the movable hole of the stabilizer to restrict the stabilizer to move only in the lateral direction, preventing longitudinal offset from causing channel misalignment. Multiple adjustment components are evenly distributed along the length of the fixed plate to ensure that the clamping force of the stabilizer on the glass plate is evenly distributed, avoiding bending deformation of thin photovoltaic glass due to local stress concentration, and adapting to the dimensional fluctuations of different batches of glass in large-scale production. (III) The L-shaped stabilizing block of the stabilizer is equipped with a first roller and a second roller to form a double stabilization of "side + top surface". The first roller rolls in contact with the side of the glass plate, guiding the glass to move along the center line and avoiding edge scratches caused by traditional sliding friction. The second roller contacts the top surface of the glass plate, limiting the glass to jump up and down and ensuring that the coating roller and the glass surface are evenly adhered during coating. The roller is made of wear-resistant polyurethane material with a smooth surface and no residue, which can prevent the glass surface from being contaminated with stains before coating, improve the coating adhesion, and prevent the film layer from falling off during later use. (iv) The slider and the handle work together to allow manual opening of the stable channel, which is convenient for feeding large-size glass. After releasing the handle, the spring drives the stabilizer to automatically reset, eliminating the need for manual adjustment of the channel width. After resetting, the centerline deviation of the channel is small, reducing operational errors. The guide roller on the slider further assists in the initial centering of the glass. When feeding, the glass is first corrected by the guide roller and then enters the stable channel for precise positioning, which improves the feeding efficiency and meets the needs of large-scale production of photovoltaic glass.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols 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 are only used to explain this utility model, and should not be construed as limiting this utility model.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0022] Please see Figures 1-3 An adaptive photovoltaic glass coating machine includes a worktable 1, a coating machine body 2, and a conveyor belt 3. The coating machine body 2 is mounted on the worktable 1. The conveyor belt 3 passes through the coating machine body 2 and is located below the coating roller. Fixed plates 4 are installed on both sides of the feed end of the conveyor belt 3 on the worktable 1. Stabilizers 5 are provided on the opposite sides of the two fixed plates 4, and the stabilizers 5 are connected to the fixed plates 4 through multiple adjustable spacing components 6. A stable channel for the glass plate 12 to pass through is formed between the two stabilizers 5. The stable channel is aligned with the center line of the coating machine body 2 and its width is adjustable. To address the issues of "poor alignment of glass plate feeding and low coating accuracy" in traditional coating machines, this device achieves a breakthrough through "symmetrical stabilizer + adjustable channel". The fixed plate 4 is fixed on both sides of the feed end of the conveyor belt, and the stabilizer 5 is connected through the adjustable distance component 6 to form a stable channel aligned with the center line of the coating machine. The channel width can be adapted to various sizes of photovoltaic glass. After the glass plate 12 enters the channel, the stabilizer can guide it to be conveyed along the center line to ensure precise docking with the coating roller inside the coating machine, reduce the uniformity error of the coating thickness, and improve the light transmittance of the photovoltaic glass. At the same time, the adjustable design eliminates the need to replace special fixtures and is suitable for production of multiple specifications. It should be noted that the coating machine body 2 is a conventional roller coating machine. The coating liquid is transferred to the coating roller through the combination roller, and then the coating roller coats the coating liquid onto the glass surface. The coating machine body 2 also has a heating channel inside, which is used to cure the coated film.

[0023] Specifically, such as Figure 2 and Figure 3As shown, the adjustment assembly 6 includes a threaded rod 61 for connecting the fixed plate 4 and the stabilizer 5. The end of the threaded rod 61 away from the stabilizer 5 slides through to the outside of the fixed plate 4 and is locked by a nut 63. A spring 62 connected between the fixed plate 4 and the stabilizer 5 is fitted on the threaded rod 61. The threaded rod 61 and nut 63 work together to manually adjust the stabilizer spacing and lock the channel width. The spring 62 provides elastic preload. When there are slight dimensional deviations in the glass plate, the stabilizer can adaptively fine-tune to avoid rigid compression that could cause damage to the glass edges. The spring also buffers the vibration of the conveyor belt to prevent the glass plate from jumping up and down and ensures smooth feeding. It is especially suitable for conveying thin photovoltaic glass.

[0024] Furthermore, the fixing plate 4 has a sleeve hole that matches the threaded rod 61. The end of the threaded rod 61 away from the stabilizer 5 is slidably sleeved with the sleeve hole. The nut 63 is threadedly connected to the threaded rod 61 and the pressure cap covers the outer opening of the sleeve hole. The sleeve hole provides a sliding guide for the threaded rod, ensuring that the stabilizer moves only laterally. The nut covers the sleeve hole opening to prevent dust from entering and affecting the sliding, while also enhancing the connection stability between the threaded rod and the fixed plate to prevent loosening over long-term use. This design makes the adjustment operation convenient, and a single person can complete the channel width adjustment.

[0025] Specifically, such as Figures 1-3 As shown, multiple adjustment components 6 are evenly distributed along the length of the fixed plate 4. A limiting plate 7 located between two adjacent adjustment components 6 is installed on the side of the fixed plate 4 near the stabilizer 5. The free end of the limiting plate 7 extends toward the stabilizer 5. The upper end of the stabilizer 5 is provided with a movable hole that is adapted to and passes through the limiting plate 7. The limiting plate 7 and the movable hole are slidably assembled. The adjusting component 6 is evenly distributed along the length of the fixed plate to ensure that the clamping force of the stabilizer on the glass plate is evenly distributed, avoiding local stress concentration that could cause the glass to bend and deform. The limiting plate 7 cooperates with the movable hole to further limit the longitudinal displacement of the stabilizer, ensuring that the center line of the channel is always aligned with the coating machine, and the centering accuracy does not decrease after long-term use.

[0026] Specifically, such as Figure 3 As shown, the stabilizer 5 includes a stabilizing block 51 disposed above the conveyor belt 3 and connected to the pitch adjustment assembly 6. The stabilizing block 51 is L-shaped. A first roller 52 corresponding to the side of the glass plate 12 and rollingly connected is installed on the short inner corner of the L-shape. A second roller 53 corresponding to the upper surface of the glass plate 12 and rollingly connected is installed on the long inner corner of the L-shape. L-shaped stabilizing block 51 is adapted to the dual stabilization requirements of glass plate "side + top surface": the first roller 52 is made of polyurethane and rolls in contact with the side of the glass plate, guiding the glass to move along the center line, reducing frictional resistance and avoiding scratches. The second roller 53 contacts the top surface, limiting the glass's vertical movement, ensuring that the coating roller and the glass surface are evenly adhered during coating, and that the roller surface is smooth and residue-free, ensuring the cleanliness of the glass and improving the adhesion of the coating.

[0027] Specifically, such as Figure 1 As shown, a chute 8 is provided on one side of the upper end face of the workbench 1, located outside the feed end opening of the conveyor belt 3. Both ends of the chute 8 are slidably fitted with sliders 9 located on the upper end face of the workbench 1. The sliders 9 are connected to the adjacent stabilizer 5 through a connecting rod 10. The slide 8 provides precise guidance for the slider 9. The slider drives the stabilizer to move synchronously through the connecting rod 10, ensuring that the stabilizers on both sides are adjusted symmetrically and the channel width changes uniformly. This structure avoids channel offset caused by unilateral adjustment and is suitable for the synchronous stability requirements when feeding large-size glass.

[0028] Furthermore, guide rollers are installed on the opposite surfaces of the two sliders 9. The outer circumference of the guide rollers is in rolling connection with the side of the glass plate 12, and the axis of the guide rollers is perpendicular to the conveying direction of the conveyor belt 3. This further assists in centering the glass plate. When feeding, the guide rollers are contacted first to initially correct the direction, and then the glass plate enters the stable channel for precise positioning, thereby improving the centering efficiency. The axis of the guide rollers is perpendicular to the conveying direction to ensure accurate guidance and avoid channel jamming caused by the glass plate entering at an angle, thus improving the feeding success rate.

[0029] Furthermore, at least one slider 9 is equipped with a handle 11 for manual opening during glass plate 12 feeding, facilitating the feeding operation of glass plate 12. After being released, it can automatically reset under the action of spring 62 to ensure the alignment of glass plate 12 with the conveying direction. The handle 11 allows for manual pulling of the stabilizer to widen the channel opening, facilitating the feeding of large-sized or irregularly shaped glass. After being released, spring 62 drives the stabilizer to automatically reset, eliminating the need for manual adjustment of the channel width and significantly improving feeding efficiency. The automatic reset function also ensures that the centerline of the channel is not offset, reducing human operation errors.

[0030] In summary, this coating machine achieves adaptive centering and stable conveying through its mechanical structure, eliminates complex electrical control components, reduces the failure rate and maintenance costs, and ensures coating accuracy and efficiency, fully meeting the production requirements of high light transmittance and high uniformity for photovoltaic glass.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
