Description

Technical Field

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

[0002] The solar thermoelectric coupling module can simultaneously generate electricity and heat. Specifically, it is composed of a thin-film photovoltaic cell and a thermoelectric module. In this module, solar energy is applied in different wavelength bands. For example, visible light is sent into the thin-film photovoltaic cell for power generation, 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 mutual influence of their temperatures due to heat conduction. Compared with a common solar photovoltaic cell composed of a backplane, a photovoltaic cell, and a light-transmitting plate, the solar thermoelectric coupling module also has a penetration interference layer, an antireflection layer, a metal reflection layer, and a thermoelectric module between the backplane and the photovoltaic cell. When laminating multiple layers, air bubble phenomena are likely to occur. Due to the presence of EVA glue, local closed spaces will be formed, and simply evacuating the air cannot completely remove the air bubbles. Therefore, during lamination, the air bubbles are directly sealed inside the module, affecting the utilization rate of solar energy. Existing vacuum lamination equipment, such as a lamination equipment for photovoltaic module production disclosed in the Chinese patent authorization publication number: CN118919591B, drives an elastic airbag to expand through a first driving mechanism, so that the elastic airbag squeezes the photovoltaic module. However, when this structure squeezes, it forms a surface contact on the photovoltaic module and cannot break the local closed space. There are still air bubble phenomena. In addition, during the processing of existing photovoltaic modules, manual participation is required for loading, unloading, and aligning the photovoltaic modules, resulting in a large operating labor intensity. Summary of the Invention

[0005] During operation, the solar thermoelectric coupling module to be laminated is sent to the first heating plate. Then, the hydraulic lifting platform on the gantry drives the upper die cavity to act, and the sealing strip at the bottom of the upper die cavity is elastically pressed against the sealing strip of the platen. At this time, the air extraction pump group extracts air from the first air extraction port and the second air extraction port respectively; the sealing between the upper die cavity and the platen is completed respectively, and the space formed between the heat-conducting silicone tape and the inside of the platen is sealed; at this time, the heat-conducting silicone tape presses down on the top surface and the periphery of the solar thermoelectric coupling module. Since the heat-conducting silicone tape and the periphery of the solar thermoelectric coupling module form an inclined surface structure, it does not affect the discharge of the gas inside the solar thermoelectric coupling module. Then, the first heating plate heats the bottom of the solar thermoelectric coupling module. When it is heated to the set temperature and maintained for the set time; the flexible pre-laminating unit acts, the electric heating roller is pre-heated to the set temperature, the traveling mechanism drives the sliding seat to linearly slide along the guide rail, the sliding seat synchronously drives the roller pressing chamber to linearly slide synchronously, and the electric heating roller contacts the heat-conducting silicone tape; the spring body inside the roller pressing chamber continuously pushes the roller seat downward, so that the electric heating roller continuously presses and fits onto the heat-conducting silicone tape, and the heat-conducting silicone tape transfers heat and linear roller pressure to the solar thermoelectric coupling module; from one side of the solar thermoelectric coupling module to the other side continuously by rolling, so as to exhaust all the bubbles inside the solar thermoelectric coupling module; and the air extraction pump group discharges the air from the space formed between the heat-conducting silicone tape and the platen; after the reciprocating rolling is completed in sequence, the laminating unit acts, heats to the preset temperature, then, the laminating hydraulic cylinder acts and is guided by the telescopic rod, so that the laminating plate linearly descends; at this time, the laminating plate performs secondary temperature control and pressure shaping on the solar thermoelectric coupling module; after the production is completed, the upper die cavity resets; the solar thermoelectric coupling module is sent out of the processing position.

[0007] Further, a proximity switch cooperating with the roller press chamber is fixed on the upper mold cavity; the traveling mechanism includes a traveling motor fixed on the sliding seat and bearing assemblies fixed on both sides of the top of the roller press chamber, a first driving roller is rotatably arranged on the bearing assemblies, and traveling wheels pressing against the bottom surface of the guide rail are fixed at both ends of the first driving roller; a first driving wheel is fixed in the middle of the first driving roller, and the first driving wheel is connected to the traveling motor through a first transmission belt. During operation, the traveling motor drives the first driving wheel to rotate through the first transmission belt, the first driving wheel drives the first driving roller to rotate synchronously, the traveling wheels at both ends of the first driving roller rotate synchronously, and the traveling wheels perform linear travel along the guide rail, thereby driving the sliding seat to linearly slide along the guide rail; when the heating and roller pressing are completed, the flexible pre-lamination unit resets and fits to the proximity switch; at this time, the lamination unit can perform the lamination action.

[0009] Further, the traveling mechanism includes traveling motors fixed at both ends of the sliding seat, and traveling wheels pressing against the bottom surface of the guide rail are fixed on the output shafts of the traveling motors; a double-motor structure is adopted, that is, two groups of traveling motors respectively drive the traveling wheels to rotate, and the traveling wheels travel along the guide rail to realize the linear sliding of the sliding seat along the guide rail.

[0011] Further, a feeding unit is arranged on the platen. The feeding unit includes roller supports fixed to the outer sides of the four ends of the platen. A second driving roller is installed between two opposite roller supports through bearings, and the top surface of the second driving roller is flush with the top surface of the platen. Second driving wheels are fixed to both ends of the second driving roller. A second transmission belt is sleeved between the two second driving wheels. Push hands are fixedly arranged opposite to each other on the two second transmission belts. First supports and second supports are fixedly arranged opposite to each other on the outer sides of the platform and the platen. A positioning hydraulic cylinder and a sliding sleeve are fixed to the first support. A sliding rod is slidably arranged on the sliding sleeve, and an L-shaped limit clamping seat is fixed between the sliding rod and the telescopic end of the positioning hydraulic cylinder.

When lamination is completed, the second transmission belt drives the solar coupling module to move forward through the push hands until the solar coupling module leaves the platen. The push hands on the second transmission belt enter the bottom surface of the platen and move back to the input end of the platen. At this time, the solar thermoelectric coupling module to be laminated is sent onto the platen again, and the process is repeated in sequence.

The feeding platform sends the solar thermoelectric coupling module to be laminated onto the top surface of the first heating plate. After lamination is completed, the solar thermoelectric coupling module is sent out of the lamination area through the discharging platform. The whole lamination process does not require manual intervention, and the operation is safer.

[0014] Further, the push hand includes a cross plate.

[0030] During operation, the solar thermoelectric coupling module 49 to be laminated is fed into the first heating plate 5. Then, the hydraulic lifting platform 3 on the gantry 2 drives the upper die cavity to act, and the sealing rubber strip 6 at the bottom of the upper die cavity is elastically pressed against the sealing rubber strip 6 on the platen 4. At this time, the air extraction pump group extracts air from the first air extraction port 7 and the second air extraction port 8 respectively, completing the sealing between the upper die cavity and the platen 4 and the sealing of the space formed between the heat-conducting silicone tape 12 and the inside of the platen 4. At this time, the heat-conducting silicone tape 12 presses down on the top surface and the periphery of the solar thermoelectric coupling module 49. Since the heat-conducting silicone tape 12 and the periphery of the solar thermoelectric coupling module 49 form an inclined surface structure, it does not affect the discharge of the gas inside the solar thermoelectric coupling module 49. Then, the first heating plate 5 heats the bottom of the solar thermoelectric coupling module 49 until it reaches the set temperature and maintains the set time.

The traveling mechanism drives the slide seat 14 to slide linearly along the guide rail 13, and the slide seat 14 synchronously drives the roller press chamber 15 to slide linearly synchronously. The electric heating roller press wheel 20 contacts the heat-conducting silicone tape 12. The spring body 17 inside the roller press chamber 15 continuously pushes the roller seat 16 downward, so that the electric heating roller press wheel 20 continuously presses and fits onto the heat-conducting silicone tape 12. The heat-conducting silicone tape 12 transfers heat and linear roller pressure to the solar thermoelectric coupling module 49, rolling from one side of the solar thermoelectric coupling module 49 to the other side continuously, thereby exhausting all the bubbles inside the solar thermoelectric coupling module 49, and discharging them into the space formed between the heat-conducting silicone tape 12 and the platen 4 by the air extraction pump group. After completing the reciprocating rolling, the laminating unit acts, heating to the preset temperature. Then, the laminating hydraulic cylinder 23 acts and is guided by the telescopic rod 22, so that the laminating plate 21 moves linearly downward. At this time, the laminating plate 21 performs secondary temperature control and pressure shaping on the solar thermoelectric coupling module 49. After the production is completed, the upper die cavity resets, and the solar thermoelectric coupling module 49 is sent out of the processing position.

[0031] The electric heating roller press wheel 20 includes a roller body 25. The roller body 25 is hollow at the axis, and the inside of the roller body 25 is a sandwich structure. Heat-conducting oil 26 is filled inside the roller body 25.

An electric heating tube 28 is fixed between the end covers 27, and the electric heating tube 28 passes through the axis of the roller body 25 movably. When the electric heating tube 28 (electromagnetic heating) is under intelligent temperature control and the oil temperature of the heat-conducting oil 26 reaches the set temperature, the roller body 25 contacts the heat-conducting silicone tape 12, and during the movement of the flexible pre-laminating unit, the roller body 25 rotates and moves along the bearings on the roller press chamber 15.

The traveling wheels 32 at both ends of the first driving roller 31 rotate synchronously, and the traveling wheels 32 perform linear travel along the guide rail 13, thereby driving the sliding seat 14 to linearly slide along the guide rail 13; when the heating and rolling are completed, the flexible pre-laminating unit resets and fits to the proximity switch 29; at this time, the laminating unit can perform the laminating action.
