Description

Technical Field

[0001] The present invention specifically relates to a flexible vacuum lamination processing device for a solar thermoelectric coupling module, and belongs to the technical field of vacuum lamination processing devices. Background Art

[0002] The solar thermoelectric coupling module can generate electricity and heat simultaneously. Specifically, it is composed of a thin-film photovoltaic cell and a thermoelectric module. The module divides solar energy into different bands. For example, visible light is sent to the thin-film photovoltaic cell to generate electricity, and infrared sunlight can pass through the thin-film photovoltaic cell and enter the thermoelectric module. There is no contact between the photovoltaic cell and the thermoelectric module, which can avoid the temperature between the two affecting each other due to heat conduction. Compared with ordinary solar photovoltaic cells composed of a backplane, photovoltaic cells and a transparent plate, the solar thermoelectric coupling module also has a penetrating interference layer, an anti-reflection layer, a metal reflective layer and a thermoelectric module between the backplane and the photovoltaic cell. When the multi-layer structure is laminated, bubbles are likely to appear. The presence of EVA glue will form a local enclosed space, and the bubbles cannot be completely expelled by vacuum extraction alone; thus, during lamination, the bubbles are directly enclosed inside the module, affecting the utilization rate of solar energy; existing vacuum lamination equipment, such as China Patent Authorization Announcement No.: CN118919591B, discloses a lamination equipment for photovoltaic module production, which drives the elastic airbag to expand through a first drive mechanism, so that the elastic airbag squeezes the photovoltaic module, but when this structure squeezes, it forms surface contact on the photovoltaic module and cannot destroy the local enclosed space; the bubble phenomenon still exists. In addition, during the processing of existing photovoltaic modules, manual participation is required in loading and unloading and alignment of photovoltaic modules, and the operation is labor-intensive.

[0010] During operation, the solar thermoelectric coupling module to be laminated is fed into the first heating plate, and then the hydraulic lifting platform on the gantry drives the upper mold cavity to move, and the sealing strip at the bottom of the upper mold cavity is elastically pressed against the sealing strip of the table plate. At this time, the vacuum pump group evacuates air from the first vacuum port and the second vacuum port respectively; the sealing between the upper mold cavity and the table plate and the space formed by the thermal conductive silicone cloth and the inside of the table plate are sealed respectively; at this time, the thermal conductive silicone cloth presses down the top surface and the periphery of the solar thermoelectric coupling module. Since the thermal conductive silicone cloth and the periphery of the solar thermoelectric coupling module form an inclined structure, it does not affect the exhaust of the internal gas of the solar thermoelectric coupling module. Then, the first heating plate heats the bottom of the solar thermoelectric coupling module. When heated to the set temperature and maintained for the set time, the flexible pre-lamination unit is activated, the electric heating roller is preheated to the set temperature, and the walking mechanism drives the slide along The guide rail slides linearly, and the slide synchronously drives the roller pressing bin to slide linearly, and the electric heating roller contacts the thermal conductive silicone cloth; the spring body inside the roller pressing bin continuously pushes the roller seat down, so that the electric heating roller continuously presses and presses the thermal conductive silicone cloth, and the thermal conductive silicone cloth transfers heat and linear roller pressure to the solar thermoelectric coupling module; the solar thermoelectric coupling module is continuously rolled from one side to the other side, thereby completely expelling the bubbles inside the solar thermoelectric coupling module; and the bubbles are discharged from the space formed by the thermal conductive silicone cloth and the table by the vacuum pump group; after completing the reciprocating rolling, the laminating unit is activated and heated to the preset temperature, then the laminating hydraulic cylinder is activated and guided by the telescopic rod to make the laminate go straight down; at this time, the laminate performs secondary temperature control and pressurization on the solar thermoelectric coupling module; after production is completed, the upper mold cavity is reset, and the solar thermoelectric coupling module is sent out of the processing position.

[0012] Furthermore, a proximity switch that cooperates with the roller pressing bin is fixed to the upper mold cavity; the traveling mechanism includes a traveling motor fixed to the slide and a bearing assembly fixed to both sides of the top of the roller pressing bin. A first transmission roller is rotatably mounted on the bearing assembly, and traveling wheels that press against the bottom surface of the guide rail are fixed to both ends of the first transmission roller; a first transmission wheel is fixed to the middle of the first transmission roller, and the first transmission wheel is connected to the traveling motor via a first transmission belt. During operation, the traveling motor drives the first transmission wheel to rotate via the first transmission belt, and the first transmission wheel drives the first transmission roller to rotate synchronously. The traveling wheels at both ends of the first transmission roller rotate synchronously, and the traveling wheels travel linearly along the guide rail, thereby driving the slide to slide linearly along the guide rail. After the heated roller pressing is completed, the flexible pre-lamination unit resets and contacts the proximity switch. At this point, the lamination unit can perform lamination.

[0013] Furthermore, the first transmission wheel is a sprocket or a synchronous pulley, and the first transmission belt is a transmission chain belt or a synchronous belt; a driving sprocket that cooperates with the transmission chain belt, or a driving pulley that cooperates with the synchronous belt is fixed on the travel motor.

During the pushing process, the positioning hydraulic cylinder is activated, and the positioning hydraulic cylinder pushes the limit card seat to move. When the limit card seat slides, it is linearly guided by the slide rod; when the limit card seat is pushed forward, the limit card seat limits the two sides of the solar coupling module.

During lamination, the upper mold cavity and the table are used to cooperate to form a closed space around the solar thermoelectric coupling module, and an independent negative pressure space is formed between the two sealing strips to ensure the sealing performance of the upper mold cavity and the table. During sealing, the upper mold cavity and the thermal conductive silicone cloth are used to pre-level the top surface of the solar thermoelectric coupling module and form a local vacuum environment, which can quickly evacuate the area around the solar thermoelectric coupling module, with high vacuum efficiency, and can reduce the power of the vacuum pump group; the thermal conductive silicone cloth has strong tearing resistance and can be used in the solar The top surface of the solar thermoelectric coupling module can realize pre-pressing space, and the thermal conductive silicone cloth has good thermal conductivity, which can directly transfer heat energy to the solar thermoelectric coupling module; when the electric heating roller is pressed onto the top surface of the thermal conductive silicone cloth, the bottom surface of the electric heating roller and the contact surface of the solar thermoelectric coupling module are linear structures, and the heat of the electric heating roller is used to melt the EVA, destroying the local closed space, and continuously squeezing out the bubble gas while the electric heating roller is rolling.
