[0008] In order to facilitate the docking of two groups of fixed multi-main-grid solar panels that need to be welded, the utility model is improved in that the docking device includes a groove, a threaded rod, a second slider and a second motor, and two groups of the grooves are symmetrically opened on the top of the workbench. The threaded rods are rotatably installed in the two groups of grooves, and the second sliders are threadedly installed on the two groups of threaded rods. The top walls of the two groups of the second sliders are fixedly connected to the bottom walls of the corresponding support frames, and one end of the two groups of threaded rods passes through the side walls of the grooves and is equipped with the second motor.

[0009] In order to facilitate the flipping of the welded multi-main-grid solar module, the present invention has the following improvements: the flipping device includes a third motor, wherein a group of the fixed plates are installed with the third motor away from the side walls of the rectangular block, and the output end of the third motor passes through the side walls of the fixed plates and is fixedly connected to the corresponding side walls of the rectangular block.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a welding mechanism for producing multi-busbar solar panels, which has the following beneficial effects:

[0017] The welding mechanism for producing multi-busbar solar panels uses a fixing device. The first slider drives the clamping plate to move closer to the center until the panel is clamped. This ensures that the position of the multi-busbar solar panel is stable during the welding process, improves the welding accuracy, and the stable clamping ensures that the position of the panel will not shift during welding, thereby improving the quality and consistency of the welding and providing reliable protection for subsequent welding operations, thereby improving production efficiency and product quality.

[0018] The welding mechanism for producing multi-busbar solar panels uses a docking device to enable the second motor to precisely control the rotation of the threaded rod according to a pre-set program or the operator's instructions. The rotation of the threaded rod causes the second slider to move along the threaded rod, causing the support frames to move linearly until the two groups of solar panels approach the docking point. This can achieve precise docking of the two fixed groups of multi-busbar solar panels, thereby improving welding quality and production efficiency while ensuring the safety and reliability of operation.

[0019] The welding mechanism for producing multi-busbar solar panels uses a flipping device. As the output shaft of the third motor rotates, the rectangular block and the solar panel fixed thereon also begin to rotate around the output shaft. The flipping action driven by the third motor controls the flipping angle so that it can reach the desired position. This can achieve efficient and precise flipping of the multi-busbar solar panel, providing reliable protection for subsequent multi-angle welding operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-4A welding mechanism for the production of multi-busbar solar panels, comprising a workbench 1, a welding head 2, a docking device, a fixing device and a flipping device, wherein a fixing frame 3 is fixedly installed on the top back wall of the workbench 1, a robotic arm 4 is installed on the bottom wall of the robotic arm 4, and the welding head 2 is installed on the bottom wall of the robotic arm 4, the fixing device comprises a support frame 5, a placement table 6, a fixing plate 7, a rectangular block 8, a rectangular groove 9, a bidirectional screw 10, a first motor 11, a first slider 12 and a clamping plate 13, two groups of the support frames 5 are installed on the top of the workbench 1 through the docking device, and the corresponding ends of the two groups of support frames 5 are fixedly installed with the fixing plate 7 , the corresponding ends of the two groups of fixed plates 7 are rotatably mounted with the rectangular blocks 8, the bottom walls of the two groups of rectangular blocks 8 are mounted with the placement platforms 6, the corresponding ends of the two groups of rectangular blocks 8 are provided with the rectangular grooves 9, the bidirectional screws 10 are rotatably mounted in the rectangular grooves 9, one end of the bidirectional screws 10 passes through the side walls of the rectangular blocks 8 and is mounted with the first motor 11, both ends of the bidirectional screws 10 are threadedly mounted with the first slider 12, and the side walls of the first slider 12 are mounted with the clamping plates 13. In this embodiment, when in use, the two groups of multi-busbar solar panels that need to be welded are placed on the two groups of placement platforms 6 respectively, and then After that, the two groups of first motors 11 are started respectively, and the first motors 11 drive the bidirectional screws 10 to rotate. The rotation of the bidirectional screws 10 will cause the first sliders 12 at both ends to move along the bidirectional screws 10. When the first sliders 12 move, the clamping plates 13 gradually move closer to the center until they touch both sides of the multi-busbar solar module, and the ends of the multi-busbar solar module that do not need to be welded are fixed. The rotation of the first motor 11 is continued to be adjusted to make the clamping plates 13 move closer to the center until the module is clamped, and the position of the clamping plates 13 is detected by a position sensor or a visual detection system (the position sensor or the visual detection system is a well-known technology and will not be described in detail here). The position is set to ensure that the clamping force is moderate and the position is accurate. If necessary, the rotation angle of the first motor 11 is fine-tuned to achieve the best clamping effect. After the multi-busbar solar panels are firmly clamped, the two groups of multi-busbar solar panels are brought close to each other for docking through the docking device. Then, the robotic arm 4 drives the welding head 2 to move to the specified position and starts the welding operation (the operations of all the above electronic components are controlled by the connected control system, which is a well-known technology in this technical field and will not be described in detail here). After one side of the welding is completed, the two fixed groups of multi-busbar solar panels can be flipped by the flipping device, and welding can be performed at multiple angles or on the reverse side to achieve flexible welding.

[0027] In actual use, it is further convenient to dock two groups of fixed multi-busbar solar panels that need to be welded. In this embodiment, the docking device includes a groove 14, a threaded rod 15, a second slider 16 and a second motor 17. Two groups of the grooves 14 are symmetrically opened on the top of the workbench 1. The threaded rods 15 are rotatably installed in the two groups of grooves 14. The second sliders 16 are threadedly installed on the two groups of threaded rods 15. The top walls of the two groups of the second sliders 16 are fixedly connected to the bottom walls of the corresponding support frame 5. One end of the two groups of threaded rods 15 passes through the side walls of the grooves 14 and is installed The second motor 17, after fixing the two groups of multi-main-grid solar panels to be welded by the fixing device, starts the two groups of second motors 17 respectively, and the second motor 17 rotates the threaded rod 15, and drives the second slider 16 to move along the threaded rod 15 through the threaded transmission. Since the second slider 16 is fixedly connected to the support frame 5, the support frame 5 will move with the second slider 16. According to the pre-set program or the operator's instructions, the second motor 17 accurately controls the moving distance of the support frame 5 until the two groups of solar panels are completely docked. When the components approach the docking point, the system slows down and performs fine-tuning until the two groups of components are completely docked.

[0028] In actual use, it is further convenient to flip the welded multi-busbar solar module. In this embodiment, the flipping device includes a third motor 18, wherein a group of the fixing plates 7 are installed with the third motor 18 away from the side wall of the rectangular block 8, and the output end of the third motor 18 passes through the side wall of the fixing plate 7 and is fixedly connected to the corresponding side wall of the rectangular block 8. When the module needs to be flipped, the third motor 18 is started, and the output shaft of the motor begins to rotate. As the output shaft of the third motor 18 rotates, the rectangular block 8 and the solar module fixed thereon also begin to rotate around the output shaft. The direction of rotation depends on the rotation direction of the motor, which can be clockwise or counterclockwise. When the module rotates to the required flipping angle, the control system (the angle preset by the control system) will send a signal to the motor to stop rotating. The flipping action is driven by the third motor 18, thereby realizing an automated flipping process without manual intervention, thereby improving the safety and efficiency of the operation. The flipping action driven by the third motor 18 can accurately control the flipping angle to ensure that each flip can reach the required position, which is particularly useful for double-sided welding or multi-angle welding.

[0029] In actual use, in order to further prevent the clamping plates 13 from damaging the multi-busbar solar panels that need to be fixed, in this embodiment, rubber pads are installed on the inner walls of each two corresponding groups of clamping plates 13. The rubber pads are soft and can prevent the clamping plates 13 from directly contacting the surface of the solar panels, thereby preventing scratches, indentations and other damages and protecting the integrity of the panels.

[0030] In actual use, in order to further ensure the support stability of the workbench 1, in this embodiment, support legs 19 are installed at the four corners of the bottom end of the workbench 1. The four-corner support design can provide evenly distributed support force to ensure that the workbench 1 will not tilt or shake during operation, especially when performing fine welding tasks.

[0031] Preferably, in this embodiment, a buffer pad is installed on the bottom wall of the support leg 19, which can absorb vibrations caused by machine operation or the external environment, thereby reducing welding quality problems caused by vibration during the welding process. This is especially important for precision welding operations because it can help maintain stability during the welding process.

[0032] In actual use, the stability and accuracy of the operation of the first motor 11, the second motor 17 and the third motor 18 are further guaranteed. In this embodiment, the first motor 11, the second motor 17 and the third motor 18 are all servo motors. The servo motor can control the position, speed and torque with high precision. The servo motor adopts closed-loop control and has good stability. It can avoid problems such as stalling and vibration, thereby ensuring the stability and accuracy of the operation of the first motor 11, the second motor 17 and the third motor 18.

[0033] During actual use, the structural strength of the fixing frame 3 is further enhanced. In this embodiment, the fixing frame 3 is L-shaped. The L-shaped fixing frame 3 forms a more solid frame by combining the vertical part and the horizontal part. Such a design can effectively resist bending and torsion and improve the overall rigidity.

[0034] In order to explain in detail the possible application scenarios, technical principles, specific solutions that can be implemented, and the purpose and effects of this application, the following is a detailed description of the specific embodiments listed in conjunction with the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of this application and are therefore only examples and are not intended to limit the scope of protection of this application.
