Description

Technical Field

[0001] The invention relates to the technical field of renewable energy, in particular to a photovoltaic component welding processing equipment. Background Art

[0002] Photovoltaic modules are devices that convert solar energy into electrical energy. They are mainly composed of eight materials: cells, EVA, tempered glass, backplane, solder strips, silicone, junction boxes, and frames. These modules are sealed into a whole by connecting a certain number of single-chip cells in series or parallel to prevent corrosion of the cell electrodes and interconnects. The encapsulation also prevents the cells from breaking, making outdoor installation easier. The service life of photovoltaic modules can reach 15-25 years. They are one of the core components of photovoltaic power generation systems. In photovoltaic modules, each part has its important role: (1) Cells: semiconductor sheets that convert light energy into electrical energy. Their conversion efficiency directly affects the power generation efficiency of the photovoltaic system. (2) EVA: as the seal of solar cells (3) Tempered glass: protects solar cells and has high light transmittance and mechanical strength; (4) Backplane: seals, insulates, and is waterproof. It must be resistant to aging, corrosion, and UV radiation; (5) Welding strips and junction boxes: are used to collect and transmit current to ensure the normal operation of the components; (6) Frames: provide structural strength and protect the internal structure of the components. When producing cells, the cells of photovoltaic cells need to be connected together by welding or other means. A standard photovoltaic module usually contains 60 or 72 cells, which are connected in series by copper wire or other conductive materials, which requires welding equipment.

[0003] When welding battery cells and welding ribbons, the existing welding equipment generally heats the welding ribbon first to soften it, and then uses a pressing plate to press the welding ribbon and the battery cell together to achieve the purpose of welding. In this process, the pressing plate may stick to the surface of the battery cell. When the pressing plate rises, the battery cell is not easy to detach, which affects the welding effect and reduces the yield rate. Moreover, when the existing welding equipment is in use, when the battery cell is placed on the welding ribbon, there may be a problem of inaccurate positioning of the battery cell on the welding platform, resulting in the welding position of the welding ribbon and the battery cell being offset, further reducing the welding effect and the yield rate. Therefore, the present invention designs several structures to solve the problem that the pressing plate may stick to the surface of the battery cell and the battery cell may be inaccurately positioned on the welding platform. In view of the above problems, the inventor proposes a photovoltaic module welding processing equipment for solving the above problems. Summary of the invention

When the pressing plate rises, the battery cell is not easy to detach, which affects the welding effect and reduces the yield rate; and when the existing welding equipment is used, when the battery cell is placed on the welding strip, the battery cell may be inaccurately positioned on the welding platform, resulting in the welding position of the welding strip and the battery cell being offset, further reducing the welding effect and reducing the yield rate; the purpose of the present invention is to provide a photovoltaic module welding processing equipment.

[0033] Working principle: When multiple battery cells need to be welded together, the welding strip cutting device 2 is mainly responsible for extracting and cutting the welding strip, and connecting multiple battery cells through the welding strip. This is a prior art and will not be described in detail. The conveyor belt 12 is started intermittently to rotate, and the battery cells are continuously conveyed to the bottom of the loading suction cup 917. The motor 401 is started to rotate half a circle in the counterclockwise direction, driving the notched disc, the rotating arm and the cylindrical pin to rotate with the second connecting shaft as the axis, and then driving one of the groove wheels 402 and the fourth spur gear 404 to rotate a quarter of a circle with the corresponding third connecting shaft 403 as the axis, and then driving the corresponding fifth spur gear 407 to rotate one circle with the fifth connecting shaft 406 as the axis, and then driving the circular plate 912 rotates one circle with the fifth connecting shaft 406 as the axis, thereby driving the sliding sleeve 910 to slide back and forth once along the surface of the second fixed shaft 909. In this process, the sleeve 906 and the connecting bar 908 are driven to reciprocate one round with the first fixed shaft 905 as the axis. In this process, the fan gear 907 and the swing plate 915 are driven to rotate one round with the sixth connecting shaft 913 as the axis. The loading suction cup 917 absorbs the battery cell, thereby driving the moving bar 916 and the loading suction cup 917 to move one round to transport the battery cell to the welding platform 3, and then starting the welding strip cutting device 2 to make the welding strip cutting device 2 work, extracting a section of welding rod and cutting it to make it contact with the battery cell, thereby completing the battery cell loading operation;

[0034] The motor 401 is started again to rotate half a circle in the counterclockwise direction, thereby driving another groove wheel 402 and the fourth spur gear 404 to rotate a quarter of a circle with the corresponding third connecting shaft 403 as the axis, and the fourth connecting shaft 405 rotates one circle, thereby driving the transmission effect of the third synchronous belt and the third synchronous wheel, driving the first connecting shaft 802 connected thereto to rotate one circle, and then through the transmission effect of the second synchronous belt and the second synchronous wheel, the two first connecting shafts 802 rotate one circle together, thereby driving the turntable 803 to rotate one circle with the first connecting shaft 802 as the axis, thereby driving the annular bar 807 and the slide plate 805 to slide back and forth along the slide groove, thereby driving the positioning plate 806 to reciprocate one circle, and during the process of the positioning plate 806 reciprocating one circle, it contacts the battery cell to position the battery cell on the welding platform 3;

[0035] The welding platform 3 is started to operate, and the welding ribbon and the battery cell are intermittently driven to move into the equipment box 10 and then out of the equipment box 10. When the welding ribbon and the battery cell move into the equipment box 10, the heat generated by the heating of the resistance wire softens the welding ribbon, and the cylinder 501 is started to shorten it, driving the first fixing block 502 and the lifting plate 503 to move downward, thereby driving the first mounting plate 504 and the pressure welding plate 505 to move downward. During the downward movement of the pressure welding plate 505, the first spur gear 512 moves downward accordingly and meshes with the first rack 609, that is, during the downward movement of the first spur gear 512, it rotates in the counterclockwise direction with the first rotating shaft 511 as the axis, thereby driving the square rod 515, the square tube 516 and the round block 517 to rotate in the clockwise direction with the second rotating shaft 514 as the axis, thereby driving the two third spur gears 607 to rotate in the clockwise direction with the fourth rotating shaft 514 as the axis. The shaft 605 and the sixth rotating shaft rotate in opposite directions as the axis, thereby driving the second rack 703 to move downward, and then driving the straight rod 702, the sixth mounting plate 701 and the limit bar 704 to move downward. The limit bar 704 contacts the battery cell one step earlier than the pressure welding plate 505 to limit the battery cell. When the limit bar 704 contacts the battery cell, the pressure welding plate 505 continues to move downward until the pressure welding plate 505 contacts the battery cell. At this time, the first straight gear 512 moves downward and has disengaged from the first rack 609 to reach the set distance. The pressure welding plate 505 squeezes the battery cell and the welding strip to weld the battery cell so that multiple battery cells are welded together. When the welding is completed, the cylinder 501 is started to extend it, and after undergoing the opposite movement process of the pressure welding plate 505 moving downward, the pressure welding plate 505 moves upward to the initial position, thus completing the welding operation of the welding strip and the battery cell.
