Description

Technical Field

[0001] The invention relates to the field of photovoltaic technology, and in particular to a photovoltaic component lamination device. Background Art

[0002] Photovoltaic cells are the core components of solar photovoltaic power generation systems. They are usually made of semiconductor materials such as silicon. After multiple photovoltaic cells are neatly laid out and arranged, they can be made into widely used photovoltaic panels through processes such as welding, lamination and packaging.

[0003] A vacuum laminator is a device used to laminate materials. The tempered glass panel, the first EVA film, the battery cell, the second EVA film, the glass panel and the back panel are laid out and stacked neatly in sequence and placed into the laminating chamber of the vacuum laminator. The vacuum laminator combines the layers of materials tightly through vacuuming, heating and pressurizing to form a sturdy and durable photovoltaic panel.

[0004] A silicone layer is provided at the bottom of the upper plate of the vacuum laminator. During lamination, the elasticity of the silicone is used for buffering and to evenly distribute the pressure, thereby reducing the possibility of damage to the thin and fragile battery cells due to pressure. However, both the battery cells and the materials wrapping the battery cells have thickness. When the silicone layer is pressed on the material, a concave deformation will occur. When the material sinks into the depression, the edge will be subject to lateral elastic force from the silicone. After the lateral elastic force increases to a certain extent with the pressure, the battery cells located at the edge will be slightly misaligned under the lateral elastic force. This misalignment not only easily leads to loosening between the battery cells and the welding rods, but also pushes the melted EVA film, causing gaps around the battery cells that are difficult to be filled with EVA glue, thereby reducing the lamination effect of the battery cells. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the silicone layer will be concave and deformed when pressed on the material. When the material sinks into the depression, the edge will be subjected to lateral elastic force from the silicone. After the lateral elastic force increases to a certain extent with the pressure, the battery cells located at the edge will be slightly misaligned under the lateral elastic force. A photovoltaic module lamination device is proposed.

[0009] During the process of the hydraulic rod extending to drive the silicone plate to laminate the battery cells, the mounting frame moves upward to drive the lifting and pressing frame to lift the edge of the silicone plate upward, while the limiting assembly tightens to limit the deformation of the silicone plate, and the contact pressure head applies a downward extrusion force to the silicone plate.

[0010] As a further description of a photovoltaic module lamination device of the above technology: the limiting component includes a rack slidably installed inside the mounting frame and meshing with gear 2, the bottom of the mounting frame is slidably connected with a longitudinal limiting plate and a transverse limiting plate, a spring 2 is arranged between the longitudinal limiting plate and the rack, both ends of the longitudinal limiting plate are fixedly connected with a spring telescopic rod, and the telescopic end of the spring telescopic rod is fixedly installed with an inclined block whose inclined surface is in contact with the transverse limiting plate.

[0011] As a further description of the above-mentioned technology, a photovoltaic module lamination device is provided: a spring is provided between the external frame and the mounting frame, a base plate is fixedly connected to the middle of the mounting frame, a heat conducting plate is fixedly connected to the bottom of the base plate, a heat conducting chamber is provided between the base plate and the heat conducting plate, and the silicone plate is fixed to the bottom of the heat conducting plate.

[0012] As a further description of a photovoltaic module laminating device of the above technology: both sides of the frame are provided with convex teeth embedded in the tooth grooves of the tooth plate, and the tooth grooves of the tooth plates located on both sides of the frame are staggered.

[0013] As a further description of the above technology, a photovoltaic module lamination device is provided: the touch pressure head penetrates the bottom plate and the heat conducting plate, the inner wall of the heat conducting plate at the position penetrated by the touch pressure head is provided with a spiral groove, the touch pressure head is provided with a slider embedded in the spiral groove, and the bottom end of the touch pressure head is provided with a convex ridge.

[0014] As a further description of a photovoltaic module laminating device of the above technology: a blade is fixedly installed on the touch pressure head at a position inside the heat conduction chamber, and a spring three is provided on the top of the heat conduction plate to be rotatably connected to the touch pressure head.

[0015] As a further description of a photovoltaic module lamination device of the above technology: the top end of the touch pressure head is rotatably connected to a top cap, and the top of the top cap is in contact with the frame.

[0016] As a further description of a photovoltaic module lamination device of the above technology: the longitudinal restriction plates and the transverse restriction plates are symmetrically arranged and wrapped around the silicone plate, the longitudinal restriction plates and the transverse restriction plates are retractable, and the bottom retractable end contacts the top surface of the lifting and pressing frame.

[0017] As a further description of a photovoltaic module lamination device of the above technology: the inner and outer edges of the lifting and pressing frame are bent downward.

[0018] In summary, due to the use of the above-mentioned technology, a photovoltaic module lamination device has the following beneficial effects:

[0019] During the lamination process, the bottom of the silicone plate is supported by the lifting and pressing frame, which effectively reduces the depth of the edge sinking into the silicone plate during material lamination, thereby reducing the lateral elastic force of the silicone on the battery cells at the edge when the silicone plate is concavely deformed, avoiding the battery cells at the edge from moving during lamination, thereby ensuring the lamination processing effect of the battery cells, and while the lifting and pressing frame moves, the silicone plate can be tightened and limited by the limiting component to prevent the edge of the silicone plate from convexly deforming when it is compressed, resulting in less pressure on the battery cells closer to the outside, balancing the force on all battery cells, making the battery cells evenly stressed, ensuring that each battery cell is tightly combined with the rest of the laminating materials, and further improving the lamination effect;

[0020] When the silicone plate presses the laminated material, the reverse force it receives will drive the mounting frame to slide inside the external frame. Therefore, increasing the pressing force of the silicone plate requires the external frame to move downward for a longer stroke, so that the pressure control of the silicone plate has a longer reaction time, thereby achieving more refined control of the lamination pressure, reducing the problem of hidden cracks in the battery cell caused by excessive pressure, and thus improving the yield rate of battery cell lamination;

[0021] The support force of the lifting and pressing frame on the silicone plate increases as the pressure on the silicone plate increases. As the degree of depression of the silicone plate increases, the support force of the lifting and pressing frame on the edge of the silicone plate increases to balance the depression depth of the silicone plate squeezed by the edge of the laminated material. When the extrusion pressure on the silicone plate changes, the lifting and pressing frame can still play a supporting role and reduce the lateral elastic force caused by the depression of the silicone plate. Therefore, it is convenient for the vacuum laminator to laminate materials of different thicknesses and qualities, improving versatility.

[0022] The touch head can strengthen the local pressure of the silicone plate, so that the EVA film between the adjacent welding rods of the battery cell is squeezed, the spreading area of ​​the EVA film is increased, and the dead corners on the battery cell that the EVA film cannot reach are effectively avoided, resulting in hollows, thereby improving the quality of the photovoltaic panel. In addition, since the slider is embedded in the spiral groove, the touch head rotates when it moves downward. Under the action of the convex ridges, the rotation of the touch head will knead the silicone plate, which not only expands the area of ​​the pressure position on the silicone plate, but also disperses the local pressure generated by the silicone plate to the surroundings, thereby further improving the spreading effect of the EVA film;

[0023] The contact pressure head drives the blades to move together during the movement and rotation process, so that the blades disturb the hot air in the heat conduction chamber between the bottom plate and the heat conduction plate, so that the heat in the heat conduction chamber is evenly distributed, ensuring that the EVA film is heated uniformly at all locations, uniform lamination stress, avoiding wrinkles and stratification of the EVA film, and improving the use effect of the EVA film.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology of a photovoltaic module lamination device in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figure 1-Figure 9 As shown, the present invention provides: a photovoltaic module laminating device: comprising a control body 10, a cover plate 11 is hinged on the top of the control body 10, a hydraulic rod 12 is fixedly installed on the top wall of the cover plate 11, and a silicone plate 13 is arranged below the hydraulic rod 12, and also includes:

[0039] The edge pressing mechanism 20 includes an external frame 21 fixed to the telescopic end of the hydraulic rod 12, a convex plate 22 is fixedly connected to the inner wall of the external frame 21, a mounting frame 23 and a toothed plate 27 are slidably installed inside the external frame 21, a gear 1 24 and a gear 2 25 are rotatably connected to the mounting frame 23, and the diameter of the gear 2 25 is one to two times the diameter of the gear 1 24, the bottom end of the toothed plate 27 penetrates the mounting frame 23 and the silicone plate 13 and is fixedly connected to a lifting and pressing frame 28, the convex plate 22 and the gear 1 24, the gear 2 25 The gear plate 27 meshes with each other. When the silicone plate 13 and the mounting frame 23 move upward, the gear 1 24 rotates, driving the gear 2 25 to rotate at a faster speed than the silicone plate 13 to drive the lifting and pressing frame 28 to move upward, and the bottom of the silicone plate 13 is supported around to reduce the depth of the depression caused by the edge of the silicone plate 13 being squeezed. In this process, the supporting force of the lifting and pressing frame 28 on the silicone plate 13 increases as the pressure on the silicone plate 13 increases, reducing the depth of the depression caused by the pressure on the silicone plate 13. A limiting component 29 is installed on the mounting frame 23;

[0040] The kneading unit 30 includes a frame 31 slidably mounted on the mounting frame 23, a protrusion 32 is provided at the bottom of the frame 31, and a plurality of contact pressure heads 34 are provided above the silicone plate 13. The EVA film is a thermosetting and sticky film made of ethylene-vinyl acetate copolymer, which is commonly used in the field of solar photovoltaics and used as a packaging film of photovoltaic modules. Adjacent cells are connected by welding rods, and the welding rods have a thickness so that the EVA film is not easy to enter the corner position where the welding rod and the cell are connected after melting. The contact pressure heads 34 apply local pressure to the silicone plate 13, which can strengthen the silicone plate 13 to squeeze the EVA glue around the welding rod, so that the EVA glue fully fills the corner position where the welding rod and the cell are connected, thereby improving the integrity of the photovoltaic panel after lamination and improving the quality of the photovoltaic panel;

[0041] When the hydraulic rod 12 extends to drive the silicone plate 13 to laminate the battery cells, the mounting frame 23 moves upward to drive the lifting frame 28 to lift the edge of the silicone plate 13 upward. At the same time, the limiting assembly 29 tightens to limit the deformation of the silicone plate 13, and the contact pressure head 34 applies a downward extrusion force to the silicone plate 13.

[0042] Reference Figure 6 and Figure 7 As shown, the limiting assembly 29 includes a rack 291 slidably mounted inside the mounting frame 23 and meshing with the second gear 25, a longitudinal limiting plate 293 and a transverse limiting plate 294 are slidably connected at the bottom of the mounting frame 23, a spring 292 is arranged between the longitudinal limiting plate 293 and the rack 291, both ends of the longitudinal limiting plate 293 are fixedly connected with a spring telescopic rod 295, and an inclined block 296 whose inclined surface is in contact with the transverse limiting plate 294 is fixedly mounted at the telescopic end of the spring telescopic rod 295, and the silicone plate 13 is pressed when the battery sheet is pressed. The generated deformation will be transmitted to the edge, causing the edge of the silicone plate 13 to expand outward, while reducing the downward pressure on the edge of the silicone plate 13. When the gear 25 rotates to drive the toothed plate 27 and the lifting frame 28 to move upward, it also drives the rack 291 to move, so that the rack 291 applies an extrusion force to the longitudinal limiting plate 293 toward the silicone plate 13 through the spring 292, thereby limiting the deformation of the periphery of the silicone plate 13 and squeezing the silicone plate 13, balancing the pressure difference between the edge and the middle of the silicone plate 13, and making the battery cell lamination pressure more uniform.

[0043] Reference Figure 4-Figure 6 and Figure 8As shown, a spring 26 is provided between the external frame 21 and the mounting frame 23, a base plate 210 is fixedly connected to the middle of the mounting frame 23, a heat conducting plate 33 is fixedly connected to the bottom of the base plate 210, a heat conducting chamber is provided between the base plate 210 and the heat conducting plate 33, a silicone plate 13 is fixed to the bottom of the heat conducting plate 33, and the laminated materials are glass plate, EVA film, battery cell, EVA film and back plate from bottom to top, the heat conducting plate 33 absorbs heat and transfers the heat to the silicone plate 13, so that the upper layer of EVA film is fully heated, the heating of the two layers of EVA film is balanced, and the melting speeds of the two layers of EVA film tend to be consistent.

[0044] Reference Figure 4 and Figure 6 As shown, both sides of the frame 31 are provided with convex teeth embedded in the tooth grooves of the tooth plates 27, and the tooth grooves of the tooth plates 27 located on both sides of the frame 31 are staggered. In the process of the four tooth plates 27 moving upward, the convex teeth of the frame 31 will be squeezed by the teeth of the tooth plates 27 on both sides, causing the frame 31 to swing back and forth.

[0045] Reference Fig. 9 As shown, the touch head 34 passes through the bottom plate 210 and the heat conducting plate 33, and a spiral groove 37 is provided on the inner wall of the heat conducting plate 33 at the position where the touch head 34 passes through. A slider 38 embedded in the spiral groove 37 is provided on the touch head 34, and a convex ridge 39 is provided at the bottom end of the touch head 34. When the touch head 34 moves downward, the slider 38 slides in the spiral groove 37, driving the touch head 34 to deflect, kneading the silicone plate 13, strengthening the downward pressure at a local position of the silicone plate 13, dispersing the EVA glue, and expanding the filling space of the EVA glue. The presence of the convex ridge 39 can enhance the kneading effect and further disperse the EVA glue.

[0046] A blade 35 is fixedly installed on the touch pressure head 34 at a position inside the heat conduction chamber. The blade 35 moves with the touch pressure head 34 to fully disturb the internal air of the heat conduction chamber, thereby improving the uniformity of temperature at various locations on the heat conduction plate 33, thereby allowing the EVA film to be heated evenly. A spring three 36 rotatably connected to the touch pressure head 34 is provided on the top of the heat conduction plate 33. The spring three 36 is rotatably connected to the touch pressure head 34 to facilitate the rotation of the touch pressure head 34, and the spring three 36 is always in a compressed state.

[0047] Reference Figure 6 and Fig. 9 As shown, the top of the touch head 34 is rotatably connected to a top cap 310, and the top of the top cap 310 contacts the frame 31. The protrusion 32 moves with the frame 31 to press the top cap 310 downward to drive the touch head 34 to move downward. The top cap 310 allows the touch head 34 to rotate when it moves downward.

[0048] Reference Figure 2 and Figure 5As shown, the longitudinal limiting plates 293 and the transverse limiting plates 294 are symmetrically arranged and wrapped around the silicone plate 13. The longitudinal limiting plates 293 and the transverse limiting plates 294 are used to tighten and limit the silicone plate 13 around to prevent the edges of the silicone plate 13 from convexly deforming when the silicone plate 13 is compressed, resulting in less pressure on the battery cells closer to the outside. The longitudinal limiting plates 293 and the transverse limiting plates 294 are retractable, and the bottom retractable ends are in contact with the top surface of the lifting and pressing frame 28, so that the lifting and pressing frame 28 can move up and down to support the silicone plate 13.

[0049] The inner and outer edges of the lifting and pressing frame 28 are bent downward. When the lifting and pressing frame 28 supports the silicone plate 13, the bent edges will gradually contact the deformed silicone plate 13, so that the deformation position of the silicone plate 13 is transitioned, reducing the damage to the silicone plate 13 when it is under pressure.

[0050] Working principle: Lay the laminated material on the control body 10, then cover the top plate 11, control the hydraulic rod 12 to extend and drive the external frame 21, spring 26, installation frame 23, bottom plate 210, heat conducting plate 33 and silicone plate 13 to press on the laminated material;

[0051] The silicone plate 13 moves upwards under the reverse force from the material, and while producing a depression, it drives the heat conducting plate 33, the bottom plate 210 and the mounting frame 23 to move upwards. The movement of the mounting frame 23 drives the gear 1 24 to roll on the convex plate 22, thereby driving the gear 2 25 to rotate and transport the tooth plate 27 upwards. The tooth plate 27 moves upwards and drives the lifting and pressing frame 28 to move upwards to support and lift the edge of the silicone plate 13 upwards, so that the edge of the lifting and pressing frame 28 is compressed, reducing the depression of the silicone plate 13 caused by the edge of the laminated material, thereby reducing the lateral elastic force from the inner wall of the depression of the silicone plate 13. Since the diameter of the gear 2 25 is larger than that of the gear 1 24, the speed of the silicone plate 13 moving upwards is less than that of the lifting and pressing frame 28, so that the lifting and pressing frame 28 can support the bottom edge of the silicone plate 13.

[0052] The gear 25 rotates while driving the rack 291 to move toward the direction close to the silicone plate 13, compressing the spring 292. The elastic force of the spring 292 gives the longitudinal restriction plate 293 an extrusion force toward the silicone plate 13, so that the longitudinal restriction plate 293 squeezes the edge of the silicone plate 13. The movement of the longitudinal restriction plate 293 drives the spring telescopic rod 295 and the inclined block 296 to move. The inclined block 296 drives the transverse restriction plate 294 to move toward the direction of the silicone plate 13 through the inclined surface. Therefore, the longitudinal restriction plate 293 and the transverse restriction plate 294 can limit the deformation of the silicone plate 13 around, balance the pressure difference between the edge and the middle of the silicone plate 13, so that the battery cell lamination pressure is more uniform;

[0053] When the tooth plate 27 moves upward, it drives the frame 31 and the protrusion 32 to rock back and forth. When the protrusion 32 moves to the top of the top cap 310, it presses the top cap 310 downward. The top cap 310 moves downward and drives the touch head 34 to move downward. Since the slider 38 is embedded in the spiral groove 37, the slider 38 deflects in the spiral groove 37 when the touch head 34 moves downward. Therefore, the touch head 34 rotates during the downward movement, driving the convex ridge 39 to knead the silicone plate 13, and applying pressure to the melted EVA glue on the battery cell through the silicone plate 13, so that the EVA glue is fully spread. When the protrusion 32 moves back from the top cap 310, the extension elastic force of the spring 36 drives the touch head 34 to reset.

[0054] The blade 35 fixed on the contact pressure head 34 will move and rotate together with the contact pressure head 34 to fully disturb the hot air in the heat conduction chamber between the bottom plate 210 and the heat conduction plate 33 , thereby improving the uniformity of the temperature at various locations on the heat conduction plate 33 .

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes to a photovoltaic module lamination device and its inventive concept according to the technology of the present invention, which should be covered by the protection scope of the present invention.
