Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic module laminating technical field, especially photovoltaic module laminating machine's semi-flexible laminating part and photovoltaic module laminating machine for photovoltaic module laminating machine. BACKGROUND

[0002] With the continuous development of photovoltaic technology, the size of single photovoltaic module is bigger and bigger, which makes the size of laminating machine upper box bigger and bigger, and the deformation of laminating machine upper box under high temperature environment is bigger and bigger, causing uneven pressure phenomenon of solar cell module in the packaging process, uneven thickness of laminated module, causing local defects of battery module in the packaging process, low pass rate of finished product, and insufficient utilization of battery piece and other phenomena.

[0003] Currently, there are two kinds of lamination for photovoltaic modules, one is a structure of a rubber plate pressing type laminator, and the other is a structure of a plate pressing type laminator. The rubber plate pressing type laminator mainly comprises an upper box and a lower box, a silicon rubber plate is arranged at the opening of the lower end surface of the upper box, the silicon rubber plate seals the opening of the upper box, the lower box is provided with a laminating workbench, after the upper box and the lower box are closed, a sealed cavity is formed, the silicon rubber plate divides the sealed cavity into an upper vacuum cavity and a lower vacuum cavity, the upper vacuum cavity and the lower vacuum cavity are communicated with a vacuum device and an inflation device, during lamination, the lower vacuum cavity is vacuumized and the upper vacuum cavity is inflated, so that the silicon rubber plate expands towards the lower vacuum cavity and exerts pressure on the photovoltaic module. Since the silicon rubber plate is flexible, the lower vacuum cavity is vacuumized and the upper vacuum cavity is inflated, therefore, the silicon rubber plate is wrapped around the periphery of each photovoltaic module, which causes the periphery of the photovoltaic module to be subjected to a large pressure, so that the periphery of the photovoltaic module is thinner than other parts, resulting in uneven thickness of the photovoltaic module, and the silicon rubber plate covering the photovoltaic module is frequently stretched during the lamination and curing process, especially at the positions wrapping the four edges of the photovoltaic module, the stretching deformation is large, and the silicon rubber plate is prone to damage under high pressure and high temperature. Currently, the silicon rubber plate needs to be replaced once a month, which causes downtime and increases the maintenance workload. In addition, in order to prevent the silicon rubber plate from wrapping the photovoltaic module and causing uneven lamination of the photovoltaic module, a frame is currently used to cover the photovoltaic module, and one frame is required for each photovoltaic module. Moreover, the frame needs to be reflowed by a frame reflow line, which increases the equipment investment cost and production cost. The plate pressing type laminator mainly comprises a rigid laminating plate and a laminating workbench, a pressing frame and a sealing element are arranged on the lower surface of the rigid laminating plate, when the rigid laminating plate and the laminating workbench are closed, a sealed cavity is formed, the rigid laminating plate is driven by a mechanical driving device such as a hydraulic cylinder to vacuumize and laminate the photovoltaic module. Since the laminator of this structure adopts multiple mechanical driving devices, it is difficult for the actions of the mechanical driving devices to be consistent, and as the size of the photovoltaic module becomes larger and larger, the production capacity requirement of the photovoltaic laminator becomes higher and higher, the size of the rigid laminating plate also becomes larger and larger, and the rigid laminating plate works in a high temperature environment, therefore, in order to prevent the rigid laminating plate from deforming, the thickness and rigidity of the rigid laminating plate are required to be higher and higher, the thickness is often more than 100 mm, and in order to laminate the photovoltaic module uniformly, the flatness of the surface is also required to be high, which is difficult to apply in actual production.

The width of the high-temperature-resistant flexible sealing element between the rigid laminating plate and the clamping position of the upper and lower pressing frames is greater than or equal to the width between the rigid laminating plate and the clamping position of the upper and lower pressing frames, so that the high-temperature-resistant flexible laminating plate can be in a relaxed state when it is in a non-laminating state. The lower box is located below the upper box and comprises a laminating workbench, the laminating workbench is located below the upper box body and is arranged opposite to the semi-flexible laminating component, when the upper box and the lower box are closed, the laminating workbench and the upper box body form a sealed cavity, and the semi-flexible laminating component divides the sealed cavity into an upper vacuum cavity and a lower vacuum cavity. The lower frame is sealingly and fixedly connected with the laminating workbench. The upper box further comprises a laminating plate support mechanism for overcoming the weight of the semi-flexible laminating component, under the support of the laminating plate support mechanism, the high-temperature-resistant flexible sealing element is in a relaxed state as a whole, that is, the high-temperature-resistant flexible sealing element is only subjected to the action of its own gravity and is not subjected to the action of the gravity of the rigid laminating plate. Preferably, the periphery of the high-temperature-resistant flexible sealing element is reserved with a length greater than or equal to the movement distance of the laminating plate, so that the high-temperature-resistant flexible sealing element does not have extension deformation in the laminating process. The high-temperature-resistant flexible sealing element is preferably one of a silicone rubber plate, an elastic air-tight sealing fabric, a high-air-tightness bio-based aromatic polyester elastomer material, a thermoplastic elastomer with an air-tight layer and a high-air-tightness bio-based thiophene polyester elastomer material or more than two kinds of materials.

The above-mentioned materials all have high-temperature resistance, good air-tightness and sufficient tensile strength.

[0030] The laminated board support mechanism is located above the flexible laminated board, can be arranged on the outside of the upper vacuum chamber, or can be arranged on the inside of the upper vacuum chamber, can adopt a telescopic air cylinder as the laminated board support mechanism, or can adopt an elastic support as the laminated board support mechanism. When the telescopic air cylinder is adopted as the laminated board support mechanism, the output end of the telescopic air cylinder is fixedly connected with the upper surface of the rigid laminated board, and a gas vent valve is arranged on the gas passage communicated between the upper chamber and the lower chamber of the telescopic air cylinder. When the lower vacuum chamber is vacuumized, the gas vent valve on the gas passage connected with the lower vacuum chamber is opened, the lower chamber of the telescopic air cylinder is exhausted, and the rigid laminated board is lowered. When the upper vacuum chamber is inflated, the upper chamber of the telescopic air cylinder is inflated, and the rigid laminated board is lowered. Preferably, the laminated board support mechanism is located outside the body of the upper vacuum chamber and in the sealed chamber. Preferably, the following structure is adopted, including a spring, a fixed shaft and an adjusting nut. The spring is located between the adjusting nut and the upper box body, and the spring is sleeved on the outside of the fixed shaft. The lower end of the fixed shaft is located on the inside of the upper box body and is fixedly connected with the upper surface of the rigid laminated board. The upper end of the fixed shaft is provided with a spring limiting plate. The adjusting nut is threadedly connected with the fixed shaft outside the spring limiting plate. The elasticity of the spring is adjusted so that the spring can overcome the weight of the rigid laminated board. Usually, a plurality of laminated board support mechanisms are arranged to be fixedly connected with the rigid laminated board, so that the rigid laminated board is balanced, and preferably, the rigid laminated board is kept horizontally lifted. The fixed shaft penetrates through the through hole arranged on the upper box body. When in the non-laminating state such as the feeding state or the discharging state, the laminated board support mechanism supports the rigid laminated board away from the laminating workbench. When laminating, the upper box and the lower box are closed, the upper vacuum chamber is inflated, the stress balance on the upper and lower sides of the rigid laminated board is broken, the pressure on the upper side is greater than the support force of the laminated board support mechanism, and then the rigid laminated board is lowered to press the assembly. In this process, the rigid laminated board is supported by the elastic support device and overcomes its gravity. Moreover, the width of the high-temperature-resistant flexible sealing piece at the pressing position of the rigid laminated board and the upper and lower pressing frames is greater than or equal to the distance between the rigid laminated board and the pressing frames. Therefore, the high-temperature-resistant flexible sealing piece is basically not subjected to force in the whole laminating process, and only plays a sealing role or is subjected to a small tension. Therefore, the high-temperature-resistant flexible sealing piece is not easy to be damaged, has a long service life, and theoretically, the service life is only affected by the high-temperature environment and the aging of the high-temperature-resistant flexible sealing piece. In actual production practice, the service life of the high-temperature-resistant flexible sealing piece is affected by the tension received in the laminating process. When the width of the high-temperature-resistant flexible sealing piece is smaller than the distance between the rigid laminated board and the pressing frames, the high-temperature-resistant flexible sealing piece is tensioned, and then the service life of the high-temperature-resistant flexible sealing piece is reduced after the upper vacuum chamber is inflated. However, under the action of the laminated board support mechanism, the service life of the high-temperature-resistant flexible sealing piece is much longer than that of the existing silica gel plate used as the laminated piece. Taking the silica gel plate as an example, in the existing structure, when the silica gel plate is simply used as the pressing component, the service life is 2-3 months, and when the structure of the utility model is adopted, the service life can be increased to 1 year. The laminated board support mechanism provides a support force to overcome the gravity of the rigid laminated board.By reasonable design, such as, increase the width of high temperature resistance flexible sealing piece, can make high temperature resistance sealing piece in the whole lamination process is not under stress, can further improve the service life of high temperature resistance flexible sealing piece. In the utility model, the rigid laminated plate is kept horizontal, so that the laminating pressure is uniform.

[0031] The working process of the laminating press with the structure is as follows: the rigid laminated plate is supported by the laminated plate supporting mechanism, the upper box is closed with the lower box under the driving of the driving device, and a vacuum cavity is formed, the cavity above the rigid laminated plate forms an upper vacuum cavity, and the cavity below the rigid laminated plate forms a lower vacuum cavity, the lower vacuum cavity and the upper vacuum cavity are respectively connected with the vacuum pumping device and the inflation device, the lower vacuum cavity is pumped, and then the upper part of the rigid laminated plate is inflated, the rigid laminated plate moves downward under the action of the inflation pressure and the lower vacuum, and at the same time, the high temperature resistance flexible sealing piece is stretched and moves downward, and the rigid laminated plate presses the photovoltaic module. After lamination, the upper vacuum cavity is exhausted, the lower vacuum cavity is inflated, the upper box and the lower box are separated, and the photovoltaic module is transferred out of the laminating cavity.

[0032] In order to prevent the deformation of the rigid laminated plate caused by uneven stress of the photovoltaic module during lamination, the elastic supporting plates are arranged at intervals below the rigid laminated plate, the positions of the elastic supporting plates are away from the positions of the photovoltaic modules, the elastic supporting plates can be arranged on both sides of the lamination position of each photovoltaic module, or the elastic supporting plates can be arranged on both sides of the lamination position of a plurality of photovoltaic modules, the elastic supporting plates are arranged along the length direction of the rigid laminated plate, the thickness of the elastic supporting plate is consistent with or slightly greater than the thickness of the photovoltaic module, and the thickness of the elastic supporting plate is equal to the thickness of the photovoltaic module after lamination, so that the photovoltaic module is not affected by the pressure, and the rigid laminated plate is supported. By adopting the structure, the rigid laminated plate is supported by the elastic supporting plates during lamination, and the deformation of the rigid laminated plate is prevented, and the transverse pads can be arranged along the length direction of the rigid laminated plate at both ends of the width of the rigid laminated plate below the lower pressing frame, so that the two long ends of the rigid laminated plate are supported, and the deformation of the two long ends of the rigid laminated plate during lamination is prevented.

[0033] The heating device can be arranged in the laminating workbench, and the cooling device can also be arranged. When the heating device is arranged, the laminating press is a lamination curing laminating press, and when the cooling device is arranged, the laminating press is a cooling machine.

[0034] The utility model discloses a laminator, its can set up one rigid laminated board in one sealed cavity, also can set up multiple rigid laminated boards in one sealed cavity, the position of multiple rigid laminated boards is set up corresponding with the position of photovoltaic module, and each rigid laminated board corresponds the position of at least one photovoltaic module, and also can be one rigid laminated board corresponding multiple photovoltaic module positions, and each rigid laminated board is fixed and sealed with high-temperature resistant elastic sealing element. Each rigid laminated board is provided with at least one laminated board support device. With this structure, the number of photovoltaic modules pressed by rigid laminated board can be reduced, the position precision requirement of rigid laminated board is reduced, and photovoltaic modules of different thicknesses and different shapes can be pressed in the same laminating cavity.

[0035] The utility model discloses a laminator of photovoltaic module structure, can be single layer, also can be multilayer. When it is multilayer structure, each laminator is stacked up and down. The laminator in the middle layer, the photovoltaic module high-temperature resistant conveying belt of the upper laminator doubles as the isolation belt of the upper box of the lower laminator, that is, the laminating workbench of the upper laminator and the upper box of the lower laminator are arranged to form a composite box, and the photovoltaic module high-temperature resistant conveying belt is arranged around the composite box.

[0036] The laminator with the utility model structure has the following advantages: 1. The high-temperature resistant sealing element such as silica gel plate does not contact the module, and the high-temperature resistant flexible sealing element such as silica gel plate only plays a vacuum sealing role. When the silica gel plate is designed to have a reserved laminated plate movement distance length, the silica gel plate does not extend and deform during the laminating process, greatly improving the service life of the silica gel plate. The silica gel plate is replaced once a year instead of once every three months according to the prior art.

[0037] 2. The use of the frame is cancelled, the frame reflow line is saved, and the number of employees is reduced.

[0038] 3. Compared with the flat plate pressing structure of the prior art, the strength requirement of the laminated plate is reduced, the processing difficulty is reduced, and the structure frame is not needed to be arranged to prevent thermal deformation and improve the strength of the laminated plate, effectively solving the problem that the vacuum degree cannot be increased due to deformation.
