[0002] Photovoltaic electromagnetic sheet, that is, photovoltaic electromagnetic sheet assembly, plays an important role in today's energy field. Photovoltaic electromagnetic sheet is a device that converts solar energy into electrical energy based on the photovoltaic effect. Since the 1950s, photovoltaic technology has undergone a long period of development. Early photovoltaic cells were inefficient and costly, and were mainly used in special fields such as aerospace. With the continuous advancement of technology, the efficiency of photovoltaic cells has gradually increased, and the cost has continued to decrease. They have begun to be widely used in ground power generation, distributed energy and other fields. Photovoltaic electromagnetic sheet uses the photovoltaic effect of semiconductor materials. When sunlight shines on the electromagnetic sheet, photons excite electrons in the semiconductor to generate current and voltage. This way of directly converting solar energy into electrical energy provides people with a clean and renewable source of energy. Compared with traditional fossil energy, photovoltaic electromagnetic sheets do not produce pollutants and greenhouse gases during the energy conversion process, and are environmentally friendly. In some remote areas where the power grid is difficult to cover, such as mountainous areas and islands, photovoltaic electromagnetic sheets can be used as an independent power supply system to provide basic living electricity for local residents. It is not restricted by geographical location and can be installed and used as long as there is sunlight, solving the problem of power shortage in these areas. Photovoltaic electromagnetic sheets need to be connected by precise welding to ensure that the current can be transmitted stably and efficiently. The welding device can provide uniform and firm connection points to avoid increased resistance, heating and even electrical failures caused by poor contact. Therefore, there is a particular need for a welding device for connecting photovoltaic electromagnetic sheets and an assembly process thereof.

[0003] However, the existing photovoltaic electromagnetic panels usually use traditional welding methods, which require workers to hold the welding head to weld the connections between the photovoltaic electromagnetic panels. The accuracy of manual operation is difficult to guarantee, which not only affects the reliability of the connection between the photovoltaic electromagnetic panels, but may also cause unstable current transmission and reduce the overall performance of the photovoltaic system. At the same time, the traditional hand-held welding method lacks intelligence and automation, and cannot achieve real-time monitoring and control of the welding process, making it difficult to ensure the stability and consistency of the welding quality.

[0029] See also Figure 1-10 The present invention provides a technical solution: a welding device for connecting photovoltaic electromagnetic sheets and an assembly process thereof, comprising a work cabinet 1, a cabinet door 2 is rotatably connected to one side surface of the work cabinet 1, a supporting leg 3 is fixedly connected to the bottom surface of the work cabinet 1, a workbench 4 is fixedly connected to the upper surface of the work cabinet 1, a bracket 5 is fixedly connected to the upper surface of the workbench 4, a clamping device 6 is arranged on the upper surface of the workbench 4, a welding device 7 is arranged on the inner wall surface of the bracket 5, and a cooling device 8 is arranged on the upper surface of one side of the workbench 4;

[0030] The welding device 7 includes a motor slot 701, a slide slot 702, a second motor 703, a screw rod 704, an auxiliary rod 705, a slider 706, a slide hole 707, a housing 708, a hydraulic cylinder 709, a hydraulic rod 710, a stop slot 711, a threaded slot 712, a connecting block 713, a threaded block 714, a clamping slot 715, a pulling rod 716, a stop pawl 717 and a welding head 718. The motor slot 701 is provided on one end surface of the bracket 5, the slide slot 702 is provided on the inner wall surface of the bracket 5, the second motor 703 is fixedly connected to the inner wall surface of the motor slot 701, the screw rod 704 is fixedly connected to one end surface of the second motor 703, the auxiliary rod 705 is fixedly connected to the inner wall surface of the slide slot 702, and the inner wall surface of the slide slot 702 is slidably connected to the Slider 706, the inner wall surface of slider 706 is provided with a sliding hole 707, the bottom surface of slider 706 is fixedly connected with a shell 708, the inner wall surface of shell 708 is fixedly connected with a hydraulic cylinder 709, the interior of hydraulic cylinder 709 is slidably connected with a hydraulic rod 710, the interior of hydraulic rod 710 is provided with a stop groove 711, the inner wall surface of hydraulic rod 710 is provided with a thread groove 712, the inner wall surface of hydraulic rod 710 is threadedly connected with a connecting block 713, the outer wall surface of connecting block 713 is fixedly connected with a thread block 714, the bottom surface of connecting block 713 is provided with a card groove 715, the inner wall surface of connecting block 713 is slidably connected with a pulling rod 716, one end surface of pulling rod 716 is fixedly connected with a stopping pawl 717, the connecting block 713 The bottom surface of the welding device 7 is fixedly connected with a welding head 718. Through the setting of the welding device 7, the second motor 703 in the motor slot 701 is first started, and the second motor 703 drives the screw rod 704 to rotate. Since the slider 706 is slidably connected with the auxiliary rod 705 through the sliding hole 707, and at the same time forms a transmission relationship with the screw rod 704, the rotation of the screw rod 704 causes the slider 706 to move horizontally in the sliding groove 702. In this way, the welding head 718 can be accurately moved to the position to be welded above the photovoltaic electromagnetic sheet as needed. After the horizontal position is determined, the hydraulic cylinder 709 in the shell 708 is started, and the hydraulic cylinder 709 pushes the hydraulic rod 710 to extend downward, so that the welding head 718 is close to the photovoltaic electromagnetic sheet. In the process of extending the hydraulic rod 710, the hydraulic cylinder 709 pushes the hydraulic rod 710 to extend downward. The stop groove 711 and the thread groove 712 of the connecting block 713 cooperate with the connecting block 713, and the thread block 714 on the connecting block 713 is threadedly connected with the thread groove 712 of the hydraulic rod 710 to ensure the stability of the connecting block 713 during the movement of the hydraulic rod 710. The stop pawl 717 cooperates with the stop groove 711 to prevent the thread block 714 from falling off in the thread groove 712. When the welding head 718 contacts the photovoltaic electromagnetic sheet and reaches a suitable welding pressure, the welding operation begins. When the welding head 718 needs to be replaced, the pulling rod 716 in the connecting block 713 can be pulled to disengage the stop pawl 717 from the contact with the hydraulic rod 710, and then the connecting block 713 can be easily removed from the hydraulic rod 710 through the slot 715.The welding head 718 is replaced. The whole process uses fully automatic welding instead of manual welding, avoiding the errors caused by manual welding, increasing the accuracy of welding and improving the efficiency of welding.

[0031] Furthermore, multiple groups of support feet 3 are arranged at the bottom of the work cabinet 1, and are symmetrically arranged with respect to the central axis of the work cabinet 1. Through the arrangement of the support feet 3, the multiple groups of support feet 3 can evenly disperse the weight borne by the work cabinet 1 and the photovoltaic electromagnetic sheet welding device above it to the ground. The symmetrical arrangement with respect to the central axis of the work cabinet 1 ensures balanced force in all directions, avoids tilting or instability of the work cabinet 1 due to excessive local force, and ensures the accuracy and stability of the welding operation.

[0032] Furthermore, the clamping device 6 includes a base 601, a clamping table 602, a limiting groove 603, a first motor 604, a rotating shaft 605, a threaded rod 606, a moving block 607, a limiting block 608, a mounting plate 609, a threaded hole 610, a first bolt 611, a connecting rod 612 and a clamping plate 613. The upper surface of the workbench 4 is fixedly connected with the base 601, the upper surface of the base 601 is fixedly connected with the clamping table 602, the surface of the base 601 is provided with a limiting groove 603, a side surface of the clamping table 602 is fixedly connected with the first motor 604, one end surface of the first motor 604 is fixedly connected with the rotating shaft 605, one end surface of the rotating shaft 605 is fixedly connected with the threaded rod 606, and the threaded rod 606 The outer wall surface of the movable block 607 is threadedly connected, the bottom surface of the movable block 607 is fixedly connected to the limiting block 608, the upper surface of the movable block 607 is threadedly connected to the mounting plate 609, the surface of the mounting plate 609 is provided with a threaded hole 610, the inner wall surface of the threaded hole 610 is threadedly connected to the first bolt 611, the upper surface of the mounting plate 609 is fixedly connected to a connecting rod 612, and the surface of the connecting rod 612 is fixedly connected to a clamping plate 613. Through the setting of the clamping device 6, firstly, the photovoltaic electromagnetic sheet to be welded is placed on the clamping platform 602 for clamping and fixing, and the first motor 604 on one side of the clamping platform 602 is started. The first motor 604 drives the rotating shaft 605 to rotate, and then the threaded rod 606 starts to rotate. Since the moving block 607 is threadedly connected to the threaded rod 606, under the rotation of the threaded rod 606, the moving block 607 begins to move along the axial direction of the threaded rod 606, and the limit block 608 at the bottom of the moving block 607 cooperates with the limit groove 603 on the surface of the base 601 to ensure that the moving block 607 maintains stable linear motion during the movement without rotation or deviation. As the moving block 607 moves, the clamping plate 613 above it connected by the mounting plate 609 and the connecting rod 612 also moves accordingly. When the two clamping plates 613 gradually approach the photovoltaic electromagnetic sheet, a clamping force is formed on the photovoltaic electromagnetic sheet. By accurately controlling the rotation of the first motor 604, the position of the clamping plate 613 can be adjusted to adapt to photovoltaic electromagnetic sheets of different sizes. The mounting plate 609 and the moving block 607 are connected by the first bolt 611, so that the mounting plate 609 can be disassembled and replaced as needed to adapt to clamping plates 613 of different specifications or for maintenance.

[0033] Furthermore, the rotating shaft 605 cooperates with the threaded rod 606 through the first motor 604 to form a rotating structure. The threads at both ends of the threaded rod 606 are symmetrically arranged with respect to the central axis of the threaded rod 606. Through the arrangement of the threaded rod 606, the threads at both ends of the threaded rod 606 are symmetrically arranged with respect to the central axis, so that the two moving blocks 607 can move synchronously toward the center or both sides, ensuring that the photovoltaic electromagnetic sheet is subjected to uniform force during the clamping process, thereby avoiding deformation or damage caused by uneven force.

[0034] Furthermore, the position of the limit groove 603 corresponds to the position of the limit block 608, and the inner wall size of the limit groove 603 is consistent with the outer wall size of the limit block 608. Through the setting of the limit groove 603, the moving block 607 can only move in a straight line under the drive of the threaded rod 606, thereby avoiding rotation or displacement of the moving block 607 during the movement process, ensuring that the clamping plate 613 can accurately clamp the photovoltaic electromagnetic sheet.

[0035] Furthermore, the clamping plate 613 is fixedly connected to the top of the moving block 607 through the threaded holes 610 and the first bolts 611 on the surface of the mounting plate 609. Multiple groups of the first bolts 611 are arranged on the surface of the mounting plate 609. Through the arrangement of the first bolts 611, the clamping plate 613 can be replaced according to different shapes and sizes of photovoltaic electromagnetic sheets, thereby improving the adaptability of the equipment. At the same time, when the clamping plate 613 is damaged, it can also be conveniently repaired and replaced, thereby reducing the maintenance cost of the equipment. Multiple groups of the first bolts 611 are arranged on the surface of the mounting plate 609, thereby increasing the connection strength between the clamping plate 613 and the moving block 607, thereby ensuring that the clamping plate will not loosen or fall off during the clamping process, thereby improving the stability and reliability of the clamping.

[0036] Furthermore, the second motor 703 and the screw rod 704 cooperate with each other to form a rotating structure, and two groups of auxiliary rods 705 are symmetrically arranged around the transverse center axis of the slide groove 702. Through the arrangement of the auxiliary rods 705, together with the screw rod 704, a stable support and guiding effect is provided for the slider 706. The two groups of auxiliary rods 705 can balance the force applied to the slider 706 during movement, thereby preventing the slider 706 from tilting or shaking, and improving the movement accuracy and stability of the welding head 718.

[0037] Furthermore, the slider 706 slides on the surface of the screw rod 704 through the sliding hole 707. The outer wall size of the slider 706 is consistent with the inner wall size of the slide groove 702. Through the setting of the slide groove 702, the slide groove 702 limits the movement direction of the slider 706, so that the slider 706 can only move in the horizontal direction, ensuring that the movement trajectory of the welding head 718 is accurate and providing stable working conditions for the welding operation.

[0038] Furthermore, the position of the stop groove 711 corresponds to the position of the card groove 715, and the inner wall size is consistent with the outer wall size of the stop pawl 717. Through the setting of the stop pawl 717, the connection block 713 is prevented from falling off in the thread groove 712 through the thread block 714, making the welding head 718 more firmly connected.

[0039] Furthermore, the cooling device 8 includes a water tank 801, a water storage pipe 802, a cooling pipe 803, a fixing box 804, a cooling fan 805, a sliding cover 806, a self-priming pump 807, a telescopic pipe 808, a heat dissipation fin 809, a clamping block 810, a second bolt 811, a nut 812, a nozzle 813 and a placement ring 814. The upper surface of the workbench 4 is fixedly connected with the water tank 801, the upper surface of one side of the water tank 801 is fixedly connected with the water storage pipe 802, the inner wall surface of the water tank 801 is fixedly connected with the cooling pipe 803, the upper surface of the workbench 4 is fixedly connected with the fixing box 804, and the inner bottom surface of the fixing box 804 is provided with a cooling fan. The fan 805, the upper surface of the fixed box 804 is slidably connected with a sliding cover 806, one end surface of the cooling tube 803 is fixedly connected with a self-priming pump 807, one end surface of the self-priming pump 807 is fixedly connected with a telescopic tube 808, the outer wall surface of the telescopic tube 808 is connected with a heat dissipation fin 809, the upper surface of the heat dissipation fin 809 is fixedly connected with a clamping block 810, the inner wall of the clamping block 810 is penetrated by a second bolt 811, the outer wall surface of the second bolt 811 is threadedly connected with a nut 812, one end of the telescopic tube 808 is fixedly connected with a nozzle 813, one side surface of the bracket 5 is fixedly connected with a placement ring 814, the cooling tube 803 penetrates the fixed box 804, the nozzle 813 corresponds to the placement ring 814. Through the setting of the cooling device 8, a large amount of heat will be generated when the photovoltaic electromagnetic sheet is welded. At this time, the cooling device 8 starts to work. First, the water in the water tank 801 can be replenished through the water storage pipe 802 to ensure that there is enough coolant reserve. When the welding part needs to be cooled, the self-priming pump 807 is started. The self-priming pump 807 generates suction to draw the water in the water tank 801 that has been initially cooled by the cooling pipe 803 through the cooling pipe 803. When the cooling pipe 803 passes through the fixing box 804, the cooling fan 805 inside the fixing box 804 can cool the cooling pipe 80 3 is quickly cooled down. When the water flows through the telescopic tube 808, the heat dissipation fins 809 on the outer wall surface of the telescopic tube 808 further increase the heat dissipation area and accelerate the heat dissipation. The heat dissipation fins 809 are fixed to the telescopic tube 808 by the clamping block 810, the second bolt 811 and the nut 812 to ensure that it remains stable under the action of water flow and vibration. As the water flows, it is finally sprayed out from the nozzle 813. The nozzle 813 is aimed at the welding part and sprays the cooling water on the high-temperature area to quickly reduce the temperature of the welding part. When the nozzle 813 is not needed, it can be placed on the placement ring 814 on the surface of one side of the bracket 5 for easy storage.

[0040] Working principle: First, place the photovoltaic electromagnetic sheet to be welded on the clamping table 602 for clamping and fixing, start the first motor 604 on one side of the clamping table 602, the first motor 604 drives the rotating shaft 605 to rotate, and then the threaded rod 606 starts to rotate. Since the moving block 607 is threadedly connected with the threaded rod 606, under the rotation of the threaded rod 606, the moving block 607 starts to move along the axial direction of the threaded rod 606, and the limit block 608 at the bottom of the moving block 607 cooperates with the limit groove 603 on the surface of the base 601 to ensure that the moving block 607 maintains stable linear motion during the movement process without rotation or deviation. As the moving block 607 moves, the clamping plate connected to the mounting plate 609 and the connecting rod 612 above it 613 also moves accordingly. When the two clamping plates 613 gradually approach the photovoltaic electromagnetic sheet, a clamping force is formed on the photovoltaic electromagnetic sheet. By accurately controlling the rotation of the first motor 604, the position of the clamping plate 613 can be adjusted to adapt to photovoltaic electromagnetic sheets of different sizes. The mounting plate 609 and the moving block 607 are connected by the first bolt 611, so that the mounting plate 609 can be disassembled and replaced as needed to adapt to clamping plates 613 of different specifications or for maintenance. Secondly, the second motor 703 in the motor slot 701 is started, and the second motor 703 drives the screw rod 704 to rotate. Since the slider 706 is slidably connected to the auxiliary rod 705 through the sliding hole 707, and at the same time forms a transmission relationship with the screw rod 704, the rotation of the screw rod 704 The slider 706 is moved horizontally in the slide groove 702, so that the welding head 718 can be accurately moved to the position to be welded of the photovoltaic electromagnetic sheet as needed. When the horizontal position is determined, the hydraulic cylinder 709 in the shell 708 is started, and the hydraulic cylinder 709 pushes the hydraulic rod 710 to extend downward, so that the welding head 718 is close to the photovoltaic electromagnetic sheet. In the process of extending the hydraulic rod 710, the retaining groove 711 and the threaded groove 712 inside the hydraulic rod 710 cooperate with the connecting block 713. The threaded block 714 on the connecting block 713 is threadedly connected with the threaded groove 712 of the hydraulic rod 710 to ensure the stability of the connecting block 713 during the movement of the hydraulic rod 710. The retaining pawl 717 cooperates with the retaining groove 711 to prevent the threaded block 71 4 falls off in the thread groove 712. When the welding head 718 contacts the photovoltaic electromagnetic sheet and reaches a suitable welding pressure, the welding operation begins. When the welding head 718 needs to be replaced, the pulling rod 716 in the connecting block 713 can be pulled to make the stop pawl 717 disengage from the contact with the hydraulic rod 710. Then, the connecting block 713 can be easily removed from the hydraulic rod 710 through the card slot 715 to replace the welding head 718. The whole process uses fully automatic welding instead of manual welding, avoiding the errors caused by manual welding, increasing the accuracy of welding, and improving the efficiency of welding. When the photovoltaic electromagnetic sheet is welded, a large amount of heat will be generated. At this time, the cooling device 8 starts to play a role. First,The water in the water tank 801 can be replenished through the water storage pipe 802 to ensure that there is enough coolant reserve. When the welding part needs to be cooled down, the self-priming pump 807 is started. The self-priming pump 807 generates suction to draw the water in the water tank 801 that has been initially cooled down by the cooling pipe 803 out through the cooling pipe 803. When the cooling pipe 803 passes through the fixing box 804, the cooling fan 805 inside the fixing box 804 can quickly cool down the water in the cooling pipe 803. When the water flows through the telescopic tube 808, the heat dissipation fins 809 on the outer wall surface of the telescopic tube 808 further increase the heat dissipation area and accelerate the heat dissipation. The heat dissipation fins 809 are fixed to the telescopic tube 808 by the clamping block 810, the second bolt 811 and the nut 812. On the shrink tube 808, ensure that it remains stable under the action of water flow and vibration. As the water flows, it is finally sprayed out from the nozzle 813. The nozzle 813 is aimed at the welding part and sprays cooling water on the high-temperature area to quickly reduce the temperature of the welding part. When the nozzle 813 is not needed, it can be placed on the placement ring 814 on the surface of one side of the bracket 5 for easy storage. The model of the first motor 604 is Y315S-2, the model of the second motor 703 is YE2-132S-4, the model of the hydraulic cylinder 709 is CDM2B25, and the model of the self-priming pump 807 is DSL2-12-374. In this way, a welding device for connecting photovoltaic electromagnetic sheets and its assembly process are completed. ,
