[0002] The perovskite battery module needs to complete the laying of insulating glue, bus bar, conductive glue, butyl glue, the laying of component surface glue film, the superimposed laying of the second glass or back plate and the blanking action before laminating. In the prior art, multiple processing benches are separately arranged to complete the corresponding processes, for example, four laying benches are arranged to lay insulating glue, bus bar, conductive glue and butyl glue, a glue film laying bench and a glass or back plate combining bench for combining the second glass or back plate to the photovoltaic module are also arranged. The multiple processing benches are separately arranged and processed, which not only occupies a large space and is not conducive to the layout of the equipment in the factory, but also has low processing efficiency, resulting in high production cost.

[0003] In the prior art, an integrated assembly machine has been designed and applied for a patent with the patent application number 2024217321672. In the scheme, four laying benches for laying insulating glue, bus bar, conductive glue and butyl glue are combined into an integrated laying device, which can complete the integrated machine for laying insulating glue, bus bar, conductive glue and butyl glue and realize integrated automatic laying, which can not only save space but also improve the laying efficiency. However, the scheme still has the following three problems:

[0004] (1) The glue film laying bench and the glass or back plate combining bench for combining the second glass or back plate to the photovoltaic module are not designed, so the component surface glue film cannot be attached, the second glass or back plate cannot be superimposed and laid, and the blanking action cannot be completed.

If the glue tape to be stuck is very long, the linear drive modules will drive the sticking device to move a long distance, so the length of the entire laying device will be relatively long and a large space will be occupied. Although the multiple laying benches are combined together to save space, the space saved by the scheme is limited.

[0006] (3)Each station can only paste the set material, if other material is replaced or the pasting order is changed, the above-mentioned device cannot realize the pasting action, and the compatibility is poor.

[0007] Therefore, it is necessary to provide a photovoltaic module pre-laminating integrated assembly device to solve the above technical problems.

DETAILED DESCRIPTION

[0047] Please refer to Figures 1-13 The embodiment is an integrated assembly equipment 100 before laminating photovoltaic modules, which comprises a magnetic levitation conveying line 1 for conveying photovoltaic modules, an unloading detection camera 2 for detecting the photovoltaic modules, a plurality of adhesive paste devices 3, a film laying device 4, a laminating device 5 and an unloading device 6 arranged in sequence along the conveying direction of the magnetic levitation conveying line 1; the magnetic levitation conveying line 1 comprises a magnetic levitation guide rail 11, a magnetic levitation power module 12 installed below the magnetic levitation guide rail 11 and a plurality of power trolleys 13 movably arranged on the magnetic levitation guide rail 11, and the top of each power trolley 13 is fixedly installed with a positioning and supporting plate 14 for positioning and supporting the photovoltaic modules; the film laying device 4 comprises a film supply mechanism 41 and a film carrying and laying mechanism 42 for laying the precisely cut film on the photovoltaic modules; the laminating device 5 comprises a sheet material supply bin 51, a sheet material positioning mechanism 52 and a laminating carrying mechanism 53 for carrying the sheet material on the sheet material supply bin 51 to the sheet material positioning mechanism 52 or carrying the sheet material positioned on the sheet material positioning mechanism 52 to the photovoltaic modules for laminating; and the unloading device 6 comprises an unloading buffer bin 61 and an unloading carrying mechanism 62 for carrying the photovoltaic modules on the magnetic levitation conveying line 1 to the unloading buffer bin 61.

[0048] The positioning support plate 14 is provided with a plurality of placement units for placing photovoltaic modules. In this embodiment, two placement units are provided on each positioning support plate 14, so that two photovoltaic modules can be processed at a time, thereby improving the processing efficiency. In other embodiments, the number of placement units is set according to the actual situation, which is not limited herein. The photovoltaic modules are placed on the positioning support plate 14 on the power trolley 13 from entering to leaving the magnetic levitation conveying line 1. Therefore, the power trolley 13 and the positioning support plate 14 are moved from the input end to the output end of the magnetic levitation conveying line 1. In order to realize the circulation conveying of the power trolley 13 and the positioning support plate 14, a conveying line 15 is arranged below the magnetic levitation conveying line 1. A first lifting module 16 is arranged at the head end of the magnetic levitation conveying line 1, and a second lifting module 17 is arranged at the tail end. The first lifting module 16 and the second lifting module 17 are both motor-driven lifting. The magnetic levitation power module 12 is spliced by a plurality of magnetic levitation power units. When the power trolley 13 and the positioning support plate 14 move to the output end of the magnetic levitation conveying line 1, the photovoltaic modules on the positioning support plate 14 are taken out, and then the second lifting module 17 drives the last magnetic levitation power unit, the power trolley 13 and the positioning support plate 14 to move downward together to the tail end of the conveying line 15. The conveying line 15 transmits the magnetic levitation power unit, the power trolley 13 and the positioning support plate 14 to the head end. The first lifting module 16 drives the magnetic levitation power unit, the power trolley 13 and the positioning support plate 14 to move upward together to the head end of the magnetic levitation conveying line 1, thereby realizing the circulation conveying of the positioning support plate 14. After a new photovoltaic module is placed on the positioning support plate 14, the power trolley conveys the positioning support plate 14 and the photovoltaic module to the next station for further processing.

[0049] Each of the sticking devices 3 comprises a mounting beam 37 above the magnetic levitation conveying line 1 and perpendicular to the conveying direction of the magnetic levitation conveying line 1, a first Y-axis driving member 38 arranged on the mounting beam 37, and at least one sticking mechanism 39 driven by the Y-axis driving member 38 to move in the Y direction and stick materials to the photovoltaic module. The sticking mechanism 39 can stick the same materials or different materials to the surface of the photovoltaic module, and the sticking positions and directions of different materials can be inconsistent. Therefore, the number, specific position, and specific sticking direction of the sticking mechanism 39 are set according to the actual sticking material condition of the photovoltaic module, which is not limited herein. One or more sticking mechanisms 39 are arranged on each of the sticking devices 3. When one sticking mechanism 39 is arranged, one kind of material can be stuck each time. When multiple sticking mechanisms 39 are arranged, the structures of the multiple sticking mechanisms 39 can be the same or different. When the structures of the multiple sticking mechanisms 39 are the same, multiple same materials can be stuck. When the structures of the multiple sticking mechanisms 39 are different, multiple different materials can be stuck. Therefore, the multiple sticking mechanisms 39 arranged can adapt to photovoltaic modules of different versions and stick multiple different materials to the photovoltaic modules, thereby improving the versatility of the assembling equipment.

[0050] The sticking mechanism 39 comprises a feeding member, a guiding and tensioning member, a pressing member, a pulling member, a cutting member, a rolling member, and a release paper recycling member. The feeding member, the guiding and tensioning member, the pressing member, the pulling member, the cutting member, the rolling member, and the release paper recycling member are conventional designs in the prior art, which are not described herein. When the structures of the multiple sticking mechanisms 39 are different, the basic structures of the feeding member, the guiding and tensioning member, the pressing member, the pulling member, the cutting member, and the rolling member are similar. Only slight changes are made according to different widths of materials or different versions of materials. The structure of the sticking mechanism 39 is adjusted according to the actual condition, which is a conventional application means in the prior art, which is not described herein.

[0051] The conveying direction of the magnetic levitation conveying line 1 is the X direction, the positioning support plates 14 are driven by the power trolleys 13 to move along the X direction, and the power trolleys 13 can automatically and quickly move to the next station. The mounting beams 37 extend along the Y direction, and the sticking mechanism 39 can be arranged to stick the material along the X direction or along the Y direction, which is adjusted according to the actual sticking position on the photovoltaic module and is not limited here. When the sticking mechanism 39 sticks along the Y direction, the first Y-axis driving member 38 arranged can drive the sticking mechanism 39 to move along the Y direction to realize the sticking action of the material along the Y direction; when the sticking mechanism 39 sticks along the X direction, the sticking mechanism 39 does not need to move along the X direction, and the photovoltaic module is driven by the power trolley 13 to move along the X direction to realize the sticking action of the material along the Y direction. The magnetic levitation power module 12 can control the moving speed of the power trolley 13 to ensure the sticking precision of the material. Since the movement of each power trolley 13 is under the control of the magnetic levitation, the transmission speed of the photovoltaic module and the sticking precision of the material can be significantly improved, and the production efficiency can be improved. Moreover, when the sticking mechanism 39 sticks along the X direction, the sticking mechanism 39 does not need to move along the X direction, and a driving module for driving the sticking mechanism 39 to move along the X direction is not needed. Therefore, the magnetic levitation conveying line 1 arranged cooperates with the sticking mechanism 39 to complete the sticking of the material along the X direction, which can not only significantly shorten the length of the entire assembly equipment, but also simplify the structure of the entire assembly equipment, and the structure is simple and the production cost is low.

[0052] In the embodiment, six sticking stations are arranged, and the sticking device 3 is arranged on each sticking station. Therefore, six sticking devices 3 are arranged, and the six sticking devices 3 include the first sticking device 31, the second sticking device 32, the third sticking device 33, the fourth sticking device 34, the fifth sticking device 35, and the sixth sticking device 36 arranged in sequence. The first sticking device 31, the second sticking device 32, the third sticking device 33, the fourth sticking device 34, the fifth sticking device 35, and the sixth sticking device 36 each include the mounting beam 37, the first Y-axis driving member 38, and at least one sticking mechanism 39. In the embodiment, the sticking schematic diagram of the butyl tape, the insulating tape, the busbar, and the conductive tape on the photovoltaic module is as shown in FIG. 6. Figure 13As shown, the butyl tape is pasted at the four edge positions of the photovoltaic module, the insulating tape is pasted at the position close to the short side of the photovoltaic module along the Y direction, the busbar is pasted on the insulating tape along the Y direction, and the conductive glue is pasted on the two ends of the busbar along the X direction or on the photovoltaic module along the X direction and extends out of the right edge of the photovoltaic module. Correspondingly, the number and position of the pasting mechanism 39 provided on each pasting device are as follows: the first pasting device 31 is provided with the first pasting mechanism 311 for pasting the butyl tape on the right short edge of the photovoltaic module, the second pasting device 32 is provided with the second pasting mechanism 321 for pasting the insulating tape on the photovoltaic module, the third pasting device 33 is provided with the third pasting mechanism 331 for pasting the busbar on the insulating tape, the fourth pasting device 34 is provided with the fourth pasting mechanism 341 for pasting the conductive glue on the photovoltaic module, the conductive tape is provided perpendicularly to the direction of the busbar, the fifth pasting device 35 is provided with the fifth pasting mechanism 351 for pasting the butyl tape on the front and back two opposite long edges of the photovoltaic module, and the sixth pasting device 36 is provided with the sixth pasting mechanism 361 for pasting the butyl tape on the left and right two opposite short edges of the photovoltaic module. Since the conductive tape extends out of the right edge of the photovoltaic module, two layers of butyl tapes are pasted on the right edge of the photovoltaic module, and the conductive tape is located between the two layers of butyl tapes to achieve the pasting and fixing of the conductive tape, thereby preventing the movement of the conductive tape.

[0053] If multiple insulating tapes need to be pasted on the photovoltaic module, for example, single-sided insulating tape and double-sided insulating tape, multiple first pasting mechanisms 311 with different structures can be provided on the first pasting device 31 to paste multiple insulating tapes. If multiple conductive glues need to be pasted on the photovoltaic module, multiple fourth pasting mechanisms 341 can be provided on the fourth pasting device 34 to paste multiple conductive tapes. In this embodiment, the fourth pasting mechanism 341 for pasting the conductive tape is also integrated on the third pasting device 33, and the multiple fourth pasting mechanisms 341 on the third pasting device 33 and the fourth pasting device 34 together complete the pasting of the multiple conductive tapes. Therefore, multiple pasting mechanisms 39 for pasting different materials can be integrated on each pasting device 39 according to the actual situation to improve the pasting efficiency.

[0054] In other embodiments, the pasting materials of the first pasting device 31, the second pasting device 32, the third pasting device 33, the fourth pasting device 34, the fifth pasting device 35, and the sixth pasting device 36 can be replaced according to the actual pasting material sequence on the photovoltaic module. The number and position of the pasting mechanism 39 provided on each pasting device can also be adjusted according to the pasting mode of the butyl tape, the insulating tape, the busbar, and the conductive tape on the photovoltaic module. Therefore, this scheme can adapt to photovoltaic modules of different versions and paste multiple different materials on the photovoltaic module, thereby improving the versatility of the assembly equipment.

The pulling member on the roll feeding assembly 33111 pulls two bus bars out in sequence and positions them on the positioning platforms 33112. The bending unit 33113 bends the adjacent ends of the two bus bars upward to form two straight lead wires.
