Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic module production, and in particular to a laminating device for photovoltaic module production. Background Art

[0002] Photovoltaic modules are the core of solar power generation systems. Their function is to convert solar energy into electrical energy. Photovoltaic modules are usually composed of a back panel, a lower layer of EVA film, a battery cell, an upper layer of EVA film and a tempered glass layer that are laminated together. The quality of the finished product directly determines the quality of the entire solar power generation system.

[0003] In the prior art, the lamination process of photovoltaic modules is usually to stack tempered glass, EVA film, battery cells and backplane and put them into a laminator, then evacuate the air between the layers while heating, then solidify the molten EVA material, and use laminating equipment to press and bond the two sides of the battery cells to the glass and the backplane respectively, finally making a photovoltaic module.

[0004] However, the following problems still exist during the use of the above photovoltaic module lamination equipment:

[0005] (1) When lamination begins after heating and vacuuming, it is difficult to effectively remove the bubbles generated by simply laminating the laminate directly onto the surface of the photovoltaic module. In particular, when the four sides of the laminate first contact the module, the bubbles in the middle are difficult to remove.

[0006] (2) When laminating photovoltaic modules, due to their fragility, excessive pressure may cause damage to the modules. If a large number of bubbles are generated inside the photovoltaic modules, the surface of the modules will be uneven, which will cause damage due to uneven force. Summary of the invention

[0026] Beneficial effects of the present invention:

[0027] 1. By setting a laminating mechanism, the elastic airbag is driven to expand by the first driving mechanism, so that the elastic airbag is laminated on the photovoltaic module to achieve flexible extrusion; when there are a large number of bubbles in the photovoltaic module, which makes the photovoltaic panel uneven, the elastic airbag is flexibly extruded, and the elastic airbag is filled with a uniform medium to expand the elastic airbag to squeeze the photovoltaic module, which can still ensure the uniformity of the force on the photovoltaic module and prevent the photovoltaic panel from being damaged due to uneven force;

[0028] When the elastic airbag expands downward, the bottom center of the elastic airbag first contacts the center of the photovoltaic module, that is, first squeezes the center of the photovoltaic module, and then as the elastic airbag continues to expand, the elastic airbag is squeezed and flattened on the photovoltaic module, so that the contact position between the elastic airbag and the photovoltaic module spreads from the center of the photovoltaic module to the surrounding areas, thereby squeezing the bubbles in the photovoltaic module from the middle to the surrounding areas, thereby improving the discharge efficiency of the bubbles in the photovoltaic module;

[0029] 2. By setting a guide mechanism, when the elastic airbag expands, the guide shaft guides and limits it, so that the elastic airbag first squeezes the center of the photovoltaic module when it expands; and as the elastic airbag continues to expand, the expansion of the elastic airbag will not deviate, and will not cause the photovoltaic module to deviate, thereby ensuring the lamination effect;

[0030] 3. By setting up a clamping mechanism, when the photovoltaic module is placed on the heat-conducting plate, the heat-conducting plate is driven down under the action of gravity, which can drive a pair of clamping blocks to rotate synchronously to clamp the photovoltaic panel, thereby realizing automatic positioning and clamping of the photovoltaic module.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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.

[0042] like Figure 1-8 As shown, a laminating device for producing photovoltaic modules, such as Figure 1-2 As shown, it includes a shell 1 with an inlet and outlet and a top plate 2 arranged on the shell 1; a heating mechanism 3, a vacuum mechanism 4 and a laminating mechanism 5 are arranged in the shell 1; the heating mechanism 3 is used to heat the photovoltaic module 7; the vacuum mechanism 4 is used to evacuate the shell 1; the laminating mechanism 5 is used to squeeze the photovoltaic module 7 from the middle to the surroundings to drive out the bubbles in the photovoltaic module 7.

[0043] It should be noted that the photovoltaic module 7 is first placed on the heating mechanism 3, and the photovoltaic module 7 is heated by the heating mechanism 3 to melt the adhesive film in the photovoltaic module 7. In the process of heating the photovoltaic module 7, the photovoltaic module 7 is evacuated by the vacuum mechanism 4 to remove most of the bubbles generated by the melted adhesive film. Then, the laminating mechanism 5 is driven to squeeze the photovoltaic module 7 to further drive away the bubbles in the photovoltaic module 7 and improve the lamination effect.

[0044] like Figure 1-3 As shown, the laminating mechanism 5 includes an elastic airbag 51 arranged in the shell 1 and a first driving mechanism for driving the elastic airbag 51 to expand or contract; when the first driving mechanism drives the elastic airbag 51 to expand, the elastic airbag 51 cooperates with the shell 1 to squeeze the photovoltaic component 7 to expel the bubbles in the photovoltaic component 7.

[0045] It should be noted that, the elastic airbag 51 is driven to expand by the first driving mechanism, so that the elastic airbag 51 laminates the photovoltaic component 7 to achieve flexible extrusion; when there are a large number of bubbles in the photovoltaic component 7, which makes the photovoltaic panel uneven, through the flexible extrusion of the elastic airbag 51, by filling the elastic airbag 51 with a uniform medium to make the elastic airbag 51 expand and squeeze the photovoltaic component 7, the uniformity of force on the photovoltaic component 7 can still be ensured, thereby preventing the photovoltaic panel from being damaged due to uneven force.

[0046] like Figure 1-3 As shown, the first driving mechanism includes an oil tank 52 and an oil pump 53 on the top plate 2; one end of the oil pump 53 is connected to the oil tank 52, and the other end of the oil pump 53 is connected to the elastic airbag 51; a pressure sensor is arranged between the elastic airbag 51 and the oil pump 53, and the pressure sensor is used to detect the oil pressure in the elastic airbag 51; the elastic airbag 51 is a hemispherical structure, so that when the elastic airbag 51 expands, one side of the elastic airbag 51 first contacts the center position of the photovoltaic module 7.

[0047] It should be noted that the oil in the oil tank 52 is introduced into the elastic airbag 51 through the oil pump 53, so that the elastic airbag 51 is forced to expand. The elastic airbag 51 is arranged above the photovoltaic module 7. When the elastic airbag 51 expands, the volume increases under the action of gravity, and the photovoltaic module 7 is pressed downward. The hemispherical structure of the elastic airbag 51 is set, so that when the elastic airbag 51 expands downward, the bottom center of the elastic airbag 51 first contacts the center of the photovoltaic module 7, that is, the center of the photovoltaic module 7 is first pressed, and then as the elastic airbag 51 continues to expand, the elastic airbag 51 is squeezed and flattened on the photovoltaic module 7, so that the elastic airbag 51 and the photovoltaic module The contact position of the component 7 spreads from the center of the photovoltaic module 7 to the surroundings, thereby squeezing the bubbles in the photovoltaic module 7 from the middle to the surroundings, thereby improving the discharge efficiency of the bubbles in the photovoltaic module 7; during the expansion of the elastic airbag 51, the pressure of the oil in the elastic airbag 51 is monitored in real time by the pressure sensor to ensure that the oil pressure in the elastic airbag 51 is within a suitable range, that is, the pressure of the photovoltaic module 7 exerted by the expansion of the elastic airbag 51 is controlled within a suitable range; it can be understood that the pressure sensor is a prior art, and in order to adapt to the high temperature environment during lamination, the pressure sensor can be a high-temperature hydraulic sensor, which is a prior art and is not drawn in the figure and will not be described in detail;

[0048] By using oil as a medium to drive the elastic airbag 51 to expand, and cooperating with the flexible structure of the elastic airbag 51, the force uniformity of the photovoltaic module 7 can be ensured; and because it is in a high temperature state during the lamination process, the oil, as a high boiling point medium, will not drive the elastic airbag 51 to expand excessively due to high temperature, so that the expansion rate of the elastic airbag 51 can be effectively controlled; and in order to improve the lamination efficiency, the oil can be heated. At this time, the oil can be heat-conducting oil, which is a prior art and can be used in a high temperature environment;

[0049] The elastic airbag 51 can be made of high temperature resistant silicone material, which is a prior art and can withstand the high temperature environment during lamination, so that the elastic airbag 51 can be expanded and used normally.

[0050] like Figure 1-3 As shown, it can be understood that the present application does not limit the specific structure and installation method of the heating mechanism 3, and only one feasible embodiment is provided below; the heating mechanism 3 includes a mounting frame 31, a heat conducting plate 32 and a heater 33; the mounting frame 31 is arranged in the shell 1, the heat conducting plate 32 and the heater 33 are both arranged on the mounting frame 31, and the heat conducting plate 32 and the heater 33 are electrically connected; during lamination, the photovoltaic module 7 is arranged on the heat conducting plate 32.

[0051] It should be noted that when the photovoltaic module 7 is placed on the heat conducting plate 32 , the heat conducting plate 32 is heated by the heater 33 , thereby heating the photovoltaic module 7 , so that the adhesive film in the photovoltaic module 7 can be melted quickly, thereby facilitating the bonding of the photovoltaic module 7 .

[0052] like Figure 1-4 As shown, it can be understood that the present application does not limit the specific structure and installation method of the vacuum mechanism 4, and only one feasible embodiment is provided below; the vacuum mechanism 4 includes a vacuum pump 41, an exhaust pipe 42 and a sealing mechanism 43; the vacuum pump 41 is installed on the shell 1, the exhaust pipe 42 is arranged in the shell 1, and the output end of the vacuum pump 41 is connected to the exhaust pipe 42; the sealing mechanism 43 is used to seal the inlet and outlet on the shell 1 to form a closed space in the shell 1.

[0053] It should be noted that the inlet and outlet of the shell 1 are sealed by a sealing mechanism 43, and then the air in the shell 1 is extracted by a vacuum pump 41, and the air in the shell 1 is discharged through an exhaust pipe 42. The end of the exhaust pipe 42 plugged into the shell 1 is a wide-mouth structure, which ensures the vacuuming efficiency while reducing the air flow rate near the photovoltaic module 7 to prevent the melted film from flowing out due to excessive suction near the photovoltaic panel.

[0054] like Figure 2-4As shown, the sealing mechanism 43 includes a pressure plate 431, a side plate 432 and a driving member; the pressure plate 431 is slidably connected in the shell 1, and the side plates 432 are arranged on both sides of the pressure plate 431, and the side plates 432 are tightly attached to the inner wall of the shell 1; the driving member is used to drive the pressure plate 431 to slide; when the pressure plate 431 slides and drives the side plates 432 to completely cover the inlet and outlet of the shell 1, a closed space is formed between the side plates 432 and the shell 1, so that when the vacuum pump 41 is started, the photovoltaic component 7 can be vacuumed.

[0055] It should be noted that the pressure plate 431 is driven to descend by the driving member, thereby driving the side plate 432 to block the inlet and outlet of the shell 1. The driving member is a prior art, such as an electric push rod 433, as long as it can drive the side plate 432 to slide up and down along the inner wall of the shell 1; it can be understood that the width of the side plate 432 is greater than the width of the inlet and outlet of the shell 1, so that after the side plate 432 blocks the inlet and outlet of the shell 1, the pressure plate 431 can still be driven to continue to descend, thereby reducing the volume of the enclosed space, which is convenient for rapid vacuuming; and it can drive the elastic airbag 51 to descend and approach the photovoltaic component 7, so that the elastic airbag 51 can expand and squeeze the photovoltaic component 7.

[0056] like Figure 3-5 As shown, the laminating mechanism 5 further includes a guide mechanism 54, which includes a mounting plate 541, a guide sleeve 542 and a guide shaft 543; the elastic airbag 51 is arranged on the pressing plate 431, and the mounting plate 541 is fixedly arranged on the housing 1 (as shown in FIG. Figure 1 As shown in FIG. 5 ), the guide sleeve 542 is disposed on the mounting plate 541, one end of the guide shaft 543 is disposed on the inner wall of the bottom of the elastic airbag 51, and the other end of the guide shaft 543 is plugged into the guide sleeve 542; when the elastic airbag 51 expands or contracts, one end of the guide shaft 543 slides in the guide sleeve 542; the pressing plate 431 and the top plate 2 (as shown in FIG. 5 ) are connected to each other. Figure 1 A liquid storage cavity is formed between the mounting plate 541 and the mounting plate 542, and the output end of the oil pump 53 is connected to the liquid storage cavity; a through hole is opened on the mounting plate 541, and the liquid storage cavity is connected to the elastic airbag 51 through the through hole.

[0057] It should be noted that when the elastic airbag 51 expands, it drives the guide shaft 543 to move. The guide shaft 543 moves under the restriction of the guide sleeve 542, so that the guide shaft 543 slides along its axial direction, so that the bottom of the elastic airbag 51 can only expand along the axis of the guide shaft 543, so that the elastic airbag 51 can be squeezed with the center position of the photovoltaic module 7 when it expands; and as the elastic airbag 51 continues to expand, under the restriction of the guide shaft 543, the expansion of the elastic airbag 51 will not be offset, and will not cause the photovoltaic module 7 to be offset, thereby ensuring the lamination effect.

[0058] like Figure 2 and Figure 6-8As shown, a positioning mechanism 6 is provided on the mounting frame 31, and the positioning mechanism 6 includes a clamping mechanism 61 and a second driving mechanism 62 for driving the clamping mechanism 61 to move; the clamping mechanism 61 includes at least two pairs of clamping blocks 611; each pair of clamping blocks 611 are vertically arranged, and both ends of each clamping block 611 are provided with a connecting shaft 612, and the clamping block 611 is rotatably connected to the mounting frame 31 through the connecting shaft 612; each clamping block 611 is rotatably connected to a pair of rotating wheels 613, and the same belt 614 is tensioned on the pair of rotating wheels 613.

[0059] It should be noted that the positioning mechanism 6 is used to position the photovoltaic assembly 7 when the photovoltaic assembly 7 is laminated to prevent the photovoltaic panel from shifting during the lamination process; when the photovoltaic assembly 7 is placed on the heat conducting plate 32, the heat conducting plate 32 is pushed down by the gravity of the photovoltaic assembly 7, and the second driving mechanism 62 drives the clamping mechanism 61 to clamp and position the photovoltaic assembly 7 through the descending of the heat conducting plate 32, so that the photovoltaic assembly 7 is automatically positioned and clamped;

[0060] In the process of laminating the photovoltaic module 7, as the pressure increases, the photovoltaic module 7 will be pushed to continue to descend. At this time, the belt 614 on the clamping block 611 is in direct contact with the side of the photovoltaic module 7. When the photovoltaic module 7 descends, the belt 614 will be driven to transmit, so that there is only static friction between the photovoltaic module 7 and the belt 614, and there will be no damage caused by sliding between the side of the photovoltaic module 7 and the clamping block 611; and in order to prevent the adhesive film from melting and sticking to the belt 614, the contact surface between the belt 614 and the photovoltaic module 7 is coated with an anti-stick coating. The anti-stick coating is a prior art and will not be described in detail.

[0061] like Figure 3-4 and Figure 6-8 As shown, the second driving mechanism 62 includes a rack 621, a spur gear 622 and a second linkage mechanism 623; the spur gear 622 is coaxially arranged on the connecting shaft 612, and the rack 621 is meshed with the spur gear 622; the second linkage mechanism 623 is used to drive the rack 621 to move, so as to drive the spur gear 622 to rotate; the positioning mechanism 6 also includes a first linkage mechanism 63, and the first linkage mechanism 63 is used to drive a pair of clamping blocks 611 to rotate synchronously; the first linkage mechanism 63 includes a bevel gear 631, which is coaxially fixed to the connecting shaft 612, and the bevel gears 631 on each pair of clamping blocks 611 are meshed.

[0062] It should be noted that when the photovoltaic component 7 is placed on the heat conducting plate 32, the heat conducting plate 32 is driven downward by gravity, thereby pushing the second linkage mechanism 623 to move, and the rack 621 is driven to move through the second linkage mechanism 623, and the spur gear 622 is driven to rotate through the rack 621, and one of the clamping blocks 611 is driven to rotate through the spur gear 622, and at the same time, the rotation of the clamping block 611 drives the bevel gear 631 on the clamping block 611 to rotate, and the bevel gear 631 drives the bevel gear 631 on the other clamping block 611 to rotate, and then drives the other clamping block 611 to rotate, so that a pair of clamping blocks 611 rotate synchronously to clamp the photovoltaic panel, and then the descent of the heat conducting plate 32 drives at least two pairs of clamping blocks 611 to rotate to clamp the side of the photovoltaic panel, thereby realizing the positioning and clamping of the photovoltaic component 7.

[0063] like Figure 6-8 As shown, the second linkage mechanism 623 includes at least two oil cylinders 6231, a first piston rod 6232, a connecting pipe 6234 and a second piston rod 6235; the oil cylinder 6231 and the connecting pipe 6234 are filled with high-temperature hydraulic oil; it can be understood that the high-temperature hydraulic oil is a prior art, and the heat-resistant temperature of the high-temperature hydraulic oil is greater than 150°C; the oil cylinder 6231 is arranged on the mounting frame 31, one end of the first piston rod 6232 is slidably connected to the oil cylinder 6231 through a piston, the heat conducting plate 32 is slidably connected to the mounting frame 31, and the first piston rod The other end of 6232 is fixed to the heat conduction plate 32, one end of the connecting pipe 6234 is connected to the oil cylinder 6231, the other end of the connecting pipe 6234 is arranged on the mounting frame 31, one end of the second piston rod 6235 is connected to the connecting pipe 6234 through a piston sliding, and the other end of the second piston rod 6235 is connected to the rack 621; a first spring 6233 is arranged in the oil cylinder 6231, one end of the first spring 6233 is in conflict with the first piston rod 6232; the first spring 6233 is used to drive the first piston rod 6232 to move and then reset.

[0064] It should be noted that, after the photovoltaic module 7 is placed on the heat conducting plate 32, the heat conducting plate 32 is pushed down by gravity, and at this time, the heat conducting plate 32 pushes the first piston rod 6232 to go down, thereby compressing the first spring 6233, and at the same time, the high-temperature hydraulic oil is squeezed by the piston on the first piston rod 6232, thereby pushing the second piston rod 6235 up, and the rack 621 is driven to rise by the second piston rod 6235, and the spur gear 622 is driven to rotate by the rack 621, thereby driving the clamping block 611 to rotate, thereby clamping the photovoltaic module 7;

[0065] When laminating the photovoltaic components 7, as the pressure on the photovoltaic components 7 increases, the photovoltaic components 7 are pushed downward, causing the first spring 6233 to be further compressed, and at the same time pushing the clamping block 611 to increase the clamping force on the side of the photovoltaic components 7 to prevent the photovoltaic components 7 from offsetting when laminating.

[0066] like Figure 6-8 As shown, the second linkage mechanism 623 also includes a buffer mechanism 6236, and the buffer mechanism 6236 includes an insertion shaft 62361 and a second spring 62362; the insertion shaft 62361 is coaxially inserted into the second piston rod 6235, the rack 621 is fixed on the insertion shaft 62361, the second spring 62362 is sleeved on the insertion shaft 62361, and one end of the second spring 62362 is connected to the insertion shaft 62361, and the other end of the second spring 62362 is connected to the second piston rod 6235.

[0067] It should be noted that, as the photovoltaic component 7 descends and drives the clamping block 611 to clamp the side of the photovoltaic component 7, as the laminating thrust on the photovoltaic component 7 increases, the clamping force of the clamping block 611 on the side of the photovoltaic component 7 reaches a certain value, and as the photovoltaic component 7 continues to be pushed down, the second spring 62362 is compressed. At this time, the rack 621 keeps its position unchanged, that is, the plug shaft 62361 keeps its position unchanged, and the second piston rod 6235 is allowed to continue to rise, so as to ensure that the clamping force of the clamping block 611 on the side of the photovoltaic component 7 is appropriate, and the photovoltaic component 7 is allowed to drive the heat conducting plate 32 to continue to descend until the heat conducting plate 32 contacts the mounting frame 31, so as to achieve pressing while maintaining an appropriate clamping force on the photovoltaic component 7, thereby improving the lamination effect.
