Description

Technical Field

[0001] This utility model belongs to the technical field of photovoltaic module lamination equipment, and specifically relates to a photovoltaic module laminator and the sealing strip installation and fixing device used thereon. Background Technology

[0002] A photovoltaic module laminator includes an upper chamber and a worktable. The upper chamber comprises the upper chamber body and a pressure frame. A sealing strip is installed on the lower surface of the pressure frame. The sealing strip is used to create a seal between the upper chamber and the worktable when they are closed, thus forming a sealed chamber. The sealing strip and the lower surface of the pressure frame are embedded. Generally, silicone strips are used for the sealing strip. Because the sealed chamber needs to be inflated and evacuated during the lamination process, especially during vacuuming, the entire weight of the upper chamber presses on the sealing strip. Therefore, the sealing strip is a consumable part and needs to be replaced periodically. Currently, when replacing the sealing strip, the upper box is first raised, and maintenance workers enter the equipment to press one end of the sealing strip into the sealing groove at the lower end of the pressure frame. Therefore, space needs to be left for personnel to operate. However, the newly developed multi-layer multi-cavity photovoltaic module laminator has an upper box for each layer, and the upper box structure of each section is the same, including the upper box body and the pressure frame. Due to the limitation of production space, the space between the upper and lower layers is small, and the space between the cavities, that is, between the boxes, is also small, making it extremely difficult for personnel to enter the equipment to operate. To address this, our company has developed a device for installing the sealing strip set at the lower end of the pressure frame, so that personnel can complete the installation of the sealing strip without entering the equipment.

[0003] In addition, in the existing technology, when the laminator is multi-cavity, especially multi-layer multi-cavity, the space for disassembling and assembling the laminator is very small due to the limitation of the site, making it difficult to replace the laminator and hindering the development and widespread use of multi-layer multi-cavity laminators. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing photovoltaic module laminators, where replacing the sealing strip is extremely inconvenient due to limited space, by providing a photovoltaic module laminator and a sealing strip installation and fixing device for the same purpose.

[0005] A further objective of the present invention is to provide a laminator, particularly a multi-layer, multi-cavity laminator, that facilitates the assembly and disassembly of the adhesive sheet and sealing strip.

[0006] The technical solution to the technical problem solved by this utility model is as follows:

[0007] A sealing strip mounting and fixing device for a photovoltaic module laminator includes a connecting rod, a support, and a slider. The slider is located at one end of the connecting rod and is hinged to the connecting rod via a bracket. One end of the bracket is fixedly connected to the lower surface or side surface of the slider, and the other end is fixedly connected to the connecting rod via a hinge shaft. The other end of the connecting rod is located in a support groove provided on the support, and the length direction of the support groove is parallel to the length direction of the connecting rod.

[0008] The slider and the bracket form a "T" shape, with the slider located at the top of the bracket;

[0009] The upper surface of the slider is provided with a groove, and the length direction of the groove is parallel to the length direction of the connecting rod.

[0010] A photovoltaic module laminator includes a housing consisting of an upper housing and a lower housing. The upper housing includes an upper body and a rectangular pressing frame composed of four side frames is provided below the upper body. The lower housing includes a worktable for supporting photovoltaic modules and forming a lamination cavity with the upper body. A sealing strip is provided on the lower surface of the pressing frame for sealing with the upper housing and the worktable when the laminator is closed. The sealing strip is connected to the lower end face of the pressing frame through a sealing structure. The laminator also includes a sealing strip mounting and fixing device. The connecting rod is located below the side frame of the pressing frame where the sealing strip is to be installed. The support is provided on the upper surface of the worktable, located outside the side frame of the pressing frame where the sealing strip is to be installed and on its extension line. The slider is located directly below the side frame where the sealing strip is to be installed.

[0011] The pressure frame includes an upper pressure frame and a lower pressure frame, which are arranged opposite to each other. A glue plate is fixed between the upper and lower pressure frames. The periphery of the glue plate is clamped and fixed between the upper and lower pressure frames by a glue plate fixing device. When the upper and lower housings are closed, the glue plate separates the upper and lower housings into independent and sealed upper and lower chambers. The glue plate fixing device includes an electromagnetic glue plate fixing device. At least the glue plate fixing device used for the upper and lower pressure frames on the side of the photovoltaic module laminator perpendicular to the running direction of the photovoltaic module is an electromagnetic glue plate fixing device. The electromagnetic glue plate fixing device includes an electromagnet, a suction plate, and an electromagnetic switching device. The electromagnet is electrically connected to the electromagnetic switching device. The electromagnetic switching device controls the electromagnet to become magnetized and demagnetized. The electromagnet and the suction plate are arranged opposite to each other. The electromagnet is fixedly connected to the upper housing body or the upper pressure frame, and the suction plate is fixedly connected to the lower pressure frame.

[0012] It also includes an electromagnet mounting base, which is L-shaped. The electromagnet is located below one side of the electromagnet mounting base, and the other side of the electromagnet mounting base is used for fixed connection with the laminator. The electromagnet is fixedly connected to the upper box body or the upper pressure frame through the electromagnet mounting base.

[0013] It also includes a rubber sheet tensioning device. Each of the rubber sheet tensioning devices includes a rubber sheet tensioning plate, a rubber sheet pressure plate, and screws. The rubber sheet tensioning plate and the rubber sheet are stacked. At least two rubber sheet tensioning devices are provided on each of the four peripheries of the rubber sheet, located at both ends on the same side of the rubber sheet. The edge of the rubber sheet is sandwiched between the rubber sheet tensioning plate and the rubber sheet pressure plate, and the rubber sheet is fixed between the two by bolts. A threaded hole is provided on the surface of the rubber sheet tensioning plate perpendicular to the end of the rubber sheet. A connecting plate is provided on the upper box body or the upper pressure frame. A through hole is provided on the connecting plate. The shank of the screw passes through the through hole and is threadedly connected to the rubber sheet tensioning plate. The rubber sheet tensioning device is located outside the upper pressure frame and the lower pressure frame. The edge of the rubber sheet is tensioned on the upper box by the rubber sheet tensioning device, and the periphery of the rubber sheet surrounds the outside of the lower pressure frame.

[0014] The laminator is a multi-stage laminator, consisting of a hot pressing stage and a cooling stage, which are spaced apart. Each stage includes a housing. The hot pressing stage is used to laminate and cure the photovoltaic module, and the cooling stage is used to cool the photovoltaic module after hot pressing and curing.

[0015] The hot pressing section includes a first hot pressing section, a second hot pressing section, and a cooling section arranged sequentially and alternately. The first hot pressing section is used to apply pressure to the photovoltaic module, the second hot pressing section is used to cure the laminated photovoltaic module, and the cooling section is used to cool the laminated and cured photovoltaic module.

[0016] The laminator is a multi-layer, multi-segment laminator. The hot pressing segment and the cooling segment each include multiple chambers, and the chambers are stacked one on top of the other to form a multi-layer laminator.

[0017] The advantages and beneficial effects of this utility model are as follows:

[0018] The sealing strip installation and fixing device used in the photovoltaic module laminator with this utility model structure supports the connecting rod through a support at one end of the connecting rod, giving the connecting rod a movable fulcrum. A slider installed at the other end of the connecting rod contacts the sealing strip. By applying upward pressure to the connecting rod with a person's arm, the slider applies pressure to the sealing strip, allowing the sealing strip to be embedded and fixedly connected to the pressure frame. Moreover, the connecting rod and the support are movable and movable, allowing the connecting rod to move along its length on the support under the operation of the operator. Therefore, as long as the length direction of the connecting rod is aligned with the extension direction of the sealing strip, the slider can move along the length direction of the sealing strip, thereby continuously applying pressure to the sealing strip and connecting the entire sealing strip on the same side to the pressure frame. The operator only needs to be at the edge of the equipment to press the sealing strip into the sealing structure set on the lower end face of the pressure frame, without having to enter the equipment or the space between them. Therefore, it solves the technical problem of the limited short side space between two adjacent chambers or laminators in existing multi-segment laminators, which prevents personnel from entering to install the sealing strip.

[0019] The photovoltaic module laminator with this utility model structure has a sealing strip installation and fixing device between at least two boxes, which can install the sealing strip on the pressure frame located between the two boxes. Since no personnel need to enter between the two boxes to operate, it can be installed easily even when the distance between the two boxes is very small. This makes the operation of installing the sealing strip simple and easy, and gives the whole equipment a high space utilization rate. Attached Figure Description

[0032] The structure of this utility model will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not limiting, and cannot be used to limit the protection scope of this utility model.

[0033] like Figures 1-8As shown in the embodiment of this utility model, the photovoltaic module laminator includes a frame 1, an upper box, and a lower box, both supported and fixed by the frame 1. The upper box includes an upper body 3 and a pressure frame. The pressure frame is fixedly disposed below the periphery of the upper body and is fixedly connected to it. In the prior art, the lower opening of the upper body is usually rectangular; therefore, the pressure frame is a rectangular frame, with each side referred to as a border. A sealing strip is provided on the lower end face of the pressure frame, and the sealing strip is embedded and sealed to the lower end face of the pressure frame. It also includes a sealing strip mounting and fixing device. The sealing strip mounting and fixing device includes a connecting rod 90, a support 110, and a slider 80. The slider is located at one end of the connecting rod and is hinged to the connecting rod via a bracket 111. In this embodiment, the slider is preferably located at the top end of the connecting rod. One end of the bracket 111 is fixedly connected to the lower or side surface of the slider, and the other end is hinged to the connecting rod via a hinge shaft. The support and slider preferably form a T-shaped structure, with the slider fixedly mounted on the top of the support 111. The lower housing includes a worktable located below the lower housing body, used to close with the upper housing body, forming a lamination chamber and supporting the photovoltaic modules during lamination. When the laminator is used for laminating and / or curing the photovoltaic modules, a heating device is installed inside the worktable to form a heating plate. When the laminator is used to cool the photovoltaic modules, it may be equipped with cooling circulation pipes and a cooling circulation medium, or it may not have a cooling device and therefore does not require a heating device. The support is used to set on the upper surface of the workbench, below the side of the pressure frame where the sealing strip needs to be installed, preferably on the outside of the pressure frame. A support groove is provided on the top of the support, which is preferably a V-shaped groove, to accommodate and support the connecting rod. The extension direction of the support groove is parallel to the length direction of the side of the pressure frame where the sealing strip needs to be installed and collinear with the center line of the sealing structure provided on the pressure frame. The sealing structure provided on the pressure frame is a sealing groove or a sealing ridge. When the sealing structure on the pressure frame is a sealing groove, part of the sealing strip is located in the sealing groove. When the sealing structure is a sealing ridge, the sealing strip is provided with a corresponding sealing groove. In use, first lay the sealing strip along the length of the frame where it needs to be installed. Then, press both ends of the sealing strip firmly into the frame, suspending the sealing strip on the frame. Place the connecting rod in the support groove, with the slider facing the frame. Push the slider from one end of the frame where the sealing strip needs to be installed to the other, pressing the sealing strip that wasn't pressed onto the frame onto it. This allows the sealing groove or sealing protrusion on the frame to interlock with the sealing protrusion or sealing groove on the sealing strip, completing the installation of the sealing strip. The connecting rod can be repeatedly pushed to repeatedly press the sealing strip, ensuring a reliable connection between the sealing strip and the frame. To maintain contact between the slider and the frame strip, the hinge connection between the slider and the connecting rod should not be too loose; it should only allow rotation to prevent the slider head from tilting.To better compress the sealing strip, a straight groove can be provided on the surface of the slider that contacts the sealing strip. The groove extends from one end of the slider to the other and is a through groove. The length direction of the groove is consistent with the length direction of the connecting rod. Ideally, the center lines of the two are in the same vertical plane, and preferably the center line of the groove is in the same vertical plane. This helps the slider to move forward along the lower surface of the pressure frame.

[0034] like Figures 2-8 As shown, the photovoltaic module laminator of this embodiment includes a housing composed of an upper housing and a lower housing. The upper housing includes an upper body 2, a rectangular upper pressing frame 5 fixedly disposed below the upper body, and a rectangular lower pressing frame 3 disposed below the upper pressing frame 5. A rectangular adhesive plate 4 is disposed between the upper and lower pressing frames, and the adhesive plate is clamped and fixed between the upper and lower pressing frames. The upper and lower pressing frames are fixedly connected together by an adhesive plate fixing device to clamp and fix the adhesive plate. The lower housing includes a worktable for supporting the photovoltaic module. When the upper and lower housings are closed, the worktable and the upper housing form a sealed chamber, and the adhesive plate divides the sealed chamber into an independent upper chamber and a lower chamber.

[0035] The preferred structure of the adhesive sheet fixing device includes an electromagnet 7, a suction plate 8, and an electromagnetic switching device. The electromagnet and the electromagnetic switching device are electrically connected, and the electromagnetic switching device controls the magnetization and demagnetization of the electromagnet. The electromagnet 7 and the suction plate 8 are arranged in pairs, with one fixed on the upper pressure frame and the other on the lower pressure frame. For example, since the volume of the electromagnet is generally larger than that of the suction plate, it is usually fixed on the outer side of the upper pressure frame and / or the upper box body. The suction plate is usually fixed on the outer side of the lower pressure frame. The electromagnet is usually fixedly connected to the upper pressure frame and / or the upper box body through an electromagnetic mounting base 6. The structure of the electromagnetic mounting base that is most conducive to the installation of the electromagnet is a right-angle bend, with one right-angle side fixedly connected to the upper box and / or the upper pressure frame, and the electromagnet fixedly installed below the other right-angle side. Under normal circumstances, the edge of the adhesive sheet will be exposed outside the upper and lower pressure frames and flipped upward. Therefore, there is a certain distance between the side surface of the electromagnet and the outer surface of the upper pressure frame, which is greater than or equal to the thickness of the adhesive sheet. The suction plate is fixed to the outer surface of the lower pressure frame with bolts, or it can be fixed by welding or bonding. Its cantilever extends out of the lower pressure frame, and its length matches the length of the electromagnet. The heights of the two are also matched. When fixing the glue plate, the two are positioned opposite each other and can be attracted together. The glue plate fixing device with the above structure is simply referred to as an electromagnetic glue plate fixing device. Preferably, an electromagnetic mounting bracket 13 is provided on the side of the electromagnetic mounting base that is connected to the upper box body or the upper pressure frame. The electromagnetic mounting base is fixedly connected to the upper pressure frame or the upper box body through the electromagnetic mounting bracket. By setting the electromagnetic mounting bracket, a relatively long distance is provided between the electromagnetic mounting base and the outer surface of the upper box body or the upper pressure frame, leaving more space for the glue plate to be folded upwards for installation.

[0036] The photovoltaic module laminator of this utility model uses the above-mentioned electromagnetic glue plate fixing device on at least its short sides, that is, the upper and lower pressure frames perpendicular to the running direction, while the long sides use the existing mechanical glue plate fixing device, such as the quick clamp fixing device. Alternatively, the above-mentioned electromagnetic glue plate fixing device can be used on all four sides. When the present invention is a multi-cavity laminator, for example including a hot pressing section 20, a hot pressing section 21, and a cold pressing section 22, the upper chamber structures of the hot pressing section 1, hot pressing section 21, and hot pressing section 3 are basically the same, all including an upper chamber body, on which an upper pressure frame and a lower pressure frame are provided. The adhesive sheet is located between the upper pressure frame and the lower pressure frame, and its periphery is clamped and fixed between the upper pressure frame and the lower pressure frame. The device for fixing and clamping the upper pressure frame and the lower pressure frame is an adhesive sheet fixing device. At least the adhesive sheet fixing devices provided on the two short sides of the upper pressure frame and the lower pressure frame of the hot pressing section 2, as well as on the short sides of the upper pressure frame and the lower pressure frame adjacent to the hot pressing section 1 and the cold pressing section, adopt the above-mentioned electromagnetic adhesive sheet fixing device. The hot pressing section 1 is used to apply pressure to the photovoltaic module, the hot pressing section 2 is used to cure the photovoltaic module, and the cooling section is used to cool the photovoltaic module. The hot pressing section 1, the hot pressing section 2, and the cooling section are arranged at intervals. The best, and relatively most economical and convenient structure is one where the adhesive sheet fixing devices on the two short sides use electromagnetic adhesive sheet fixing devices, and the adhesive sheet fixing devices on the two long sides use mechanical fixing devices such as quick clamps. This ensures reliable fixing of the adhesive sheet and facilitates easy assembly and disassembly while saving on laminator manufacturing costs. Two or more adhesive sheet fixing devices can be installed along the upper and lower pressure frames on each side. Alternatively, only one hot pressing section can be installed, where lamination and curing are completed. The structure of this patent application is more suitable for multi-layer, multi-segment laminators, where each segment laminator includes at least two lamination units stacked vertically.

[0037] Preferably, a rubber sheet tensioning device is also provided, which pre-tensions the rubber sheet to fix it to the upper box body, improving the tension of the rubber sheet and preventing the installed rubber sheet from sag. This also allows for adjustment of the rubber sheet tension and provides convenient conditions for the rubber sheet fixing device to secure the rubber sheet. Figure 7 and Figure 8As shown, the rubber sheet tensioning device of this embodiment includes a tensioning screw 14, a rubber sheet pressure plate 15, and a rubber sheet tensioning plate 16. The rubber sheet pressure plate 15 and the rubber sheet tensioning plate 16 are of approximately equal length and are stacked. The edge of the rubber sheet 4 is clamped between the rubber sheet pressure plate and the rubber sheet tensioning plate. The rubber sheet pressure plate and the rubber sheet tensioning plate are fixedly connected by bolts. A corresponding through hole is provided at the clamped part of the rubber sheet for the bolt to pass through. Taking the position of the rubber sheet when it is laid flat as the description position, a threaded hole is provided on the side surface of the rubber sheet tensioning plate perpendicular to the end face of the clamped rubber sheet. The length direction of the threaded hole is parallel to the clamped rubber sheet, and the tensioning screw is threadedly connected to the threaded hole. During installation, the tensioning screw passes through the through hole provided on the connecting plate provided on the side of the upper box body, thereby fixing the rubber sheet tensioning device on the side surface of the upper box body. The rubber sheet tensioning device is located above the upper pressure frame, generally parallel to it. The connecting plate is located above the rubber sheet tensioning plate. Connecting plates and rubber sheet tensioning devices are installed at the front and rear ends and / or left and right sides of the upper chamber body. In this way, the four sides or two opposite edges of the rubber sheet can be pre-fixed to the upper chamber body by the rubber sheet tensioning device, and the edges of the rubber sheet are flipped upwards to surround the upper pressure frame or upper chamber body. When the tension of the rubber sheet needs to be adjusted, the tensioning screws are adjusted to adjust the distance between the connecting plate and the rubber sheet tensioning plate. Preferably, in a multi-cavity laminator, especially a multi-layer multi-cavity laminator, the connecting plate is positioned near the left and right sides of the short side, and tension is applied only to the parts of the rubber sheet near the two ends. Due to the thickness and hardness of the rubber sheet, the edges are folded upwards, and the diagonal plates at the four corners of the rubber sheet are tensioned, pulling the rubber sheet tight. Personnel can tension the rubber sheet onto the upper chamber body without entering between two adjacent cavities.

[0038] When replacing the rubber sheet, first remove the lower pressure frame, then lower the upper chamber and remove the locking screws to allow the rubber sheet to fall. After raising the upper chamber, move the old rubber sheet to the laminator. Lay the new rubber sheet, equipped with rubber sheet tensioning plates and pressure plates on both sides, flat on the worktable below the upper chamber body. At this point, the edges of the rubber sheet are clamped and fixed by the tensioning and pressure plates. Align the four sides of the rubber sheet with the four sides of the upper pressure frame, ensuring the tensioning and pressure plates are outside the upper pressure frame and protrude a certain distance beyond its four sides. Fold the rubber sheet protruding from the upper pressure frame upwards, insert the tensioning screws into the through holes on the connecting plate, and then thread them into the threaded holes on the tensioning plate to tension and pre-fix the rubber sheet to the upper chamber. Then raise the upper chamber, align the lower pressure frame with the upper pressure frame, and use the rubber sheet fixing device to secure the upper and lower pressure frames together, further securing the rubber sheet. This type of sheet tensioning device can easily tension and fix the sheet to the upper chamber, which is especially advantageous when the laminator has multiple cavities, for tensioning and fixing the sheet between the two cavities.

[0039] The combination of the rubber sheet fixing device and the rubber sheet tensioning device using the structure of this invention can eliminate the inconvenience of operators entering the equipment for installation, making the installation and removal of the rubber sheet convenient and quick.
