[0002] Photovoltaic modules (also called solar panels) are one of the core components of a photovoltaic power generation system. Because individual solar cells are fragile and easily corroded, direct exposure to the atmosphere can reduce photoelectric conversion efficiency due to humidity, dust, acid rain, and other factors, leading to damage and failure. To ensure that photovoltaic cells achieve the required output power and extend their lifespan, photovoltaic modules are typically fabricated using components such as photovoltaic glass, EVA film, backsheets, frames, junction boxes, interconnects, and busbars.

[0003] The production process of photovoltaic modules involves dicing, string welding, layout, stacking welding, tape application, pre-EL testing, lamination, edge trimming, external inspection, frame assembly, junction box welding and gluing, curing, insulation withstand voltage testing, IV testing, final EL inspection, appearance inspection, and packaging. Among these, key processes include string welding, layout, and stacking welding. In actual production, how to further optimize the process flow to make the connection between each process smoother and improve production efficiency is a direction that needs to be pursued in this field.

[0020] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0021] See Figure 1-4 In one embodiment of this utility model, a non-standard photovoltaic module layout and busbar integrated machine includes: a layout mechanism 1, a busbar welding mechanism 2, a conveying mechanism 3, a transfer station 4, a stacking mechanism 5, a production line 6, a support platform 7, a rear alignment component 8, a lateral alignment component 9, a control system 10, a welding strip feeding device 11, a sensor 12, a secondary frame 13, and a main frame 14.

[0022] The sub-frame 13 is located on the left side of the main frame 14. The layout mechanism 1, the bus welding mechanism 2, the conveying mechanism 3, the transfer station 4, the control system 10, the welding strip feeding device 11, and the sensor 12 are installed on the sub-frame 13. The output direction of the conveying mechanism 3 points towards the main frame 14. The layout mechanism 1, the bus welding mechanism 2, and the transfer station 4 are all located below the conveying mechanism 3 and are arranged in sequence in the direction close to the main frame 14. The layout mechanism 1 is used to input the battery strings after string welding into this integrated machine and perform layout positioning. The bus welding mechanism 2 is used to weld the battery strings after layout. The conveying mechanism 3 is used to transfer the battery strings after layout to the bus welding mechanism 2 and then transfer the battery strings to the transfer station 4 after welding.

[0023] The welding strip feeding device 11 is installed below the busbar welding mechanism 2 and is used to feed welding strips to the busbar welding mechanism 2. Multiple sensors 12 are provided and are installed above the layout mechanism 1 and the transfer platform 4. The sensors 12 above the transfer platform 4 can detect the presence or absence of workpieces on the transfer platform 4. The transfer platform 4 is the connection between welding and photovoltaic module assembly. The control system 10 is connected to the layout mechanism 1, the busbar welding mechanism 2, the conveying mechanism 3, the control system 10, the welding strip feeding device 11, and the sensors 12 through circuits, so that the various mechanisms can work together.

[0024] The layout mechanism 1 includes a timing belt and a correction component. The timing belt is input in the forward and backward direction, and the correction component is located on the left and right sides of the timing belt. When the battery string passes through the timing belt, the sensor 12 detects the battery string, and then the control system 10 issues a command to control the correction component to correct and position the battery string.

[0025] The bus welding mechanism 2 includes a transverse platform and a welding torch driven by the transverse platform. Under the drive of the transverse platform, the welding torch can perform welding in the width direction of the battery string.

[0026] The conveying mechanism 3 includes a series moving platform and a first gripper driven by the series moving platform. The series moving platform can drive the first gripper to move left and right and up and down to achieve the purpose of grabbing, moving and putting down. In implementation, the series moving platform can be composed of components such as a synchronous belt, synchronous wheel, bracket, cylinder and motor, which adopts the existing technology and will not be described in detail in this application; the first gripper is composed of a vacuum generator and multiple suction cups connected to the vacuum generator.

[0027] The stacking mechanism 5, production line 6, support platform 7, rear alignment component 8, and lateral alignment component 9 are mounted on the main frame 14. The stacking mechanism 5 is located above the production line 6 and is used to prepare the workpieces on the transfer table 4 and the photovoltaic modules on the support platform 7 for lamination. The rear alignment component 8 and lateral alignment component 9 are mounted on the outside of the support platform 7 and are used to align and position the photovoltaic modules that flow into the integrated machine through the production line 6. In this embodiment, the stacking mechanism 5, production line 6, support platform 7, rear alignment component 8, and lateral alignment component 9 are all connected to the control system 10.

[0028] The stacking mechanism 5 includes a robotic arm 501, a drive module 502, and a second gripper 503. The robotic arm 501 is connected to the output end of the drive module 502, and the drive module 502 can drive the robotic arm 501 to move back and forth above the support platform 7. The second gripper 503 has the same structure as the first gripper and is located at the execution end of the robotic arm 501.

[0029] The production line 6 adopts existing technology and includes components such as a drive motor, a bobbin 601, and rollers 602. The support platform 7 includes a lifting cylinder 701, a support frame driven by the lifting cylinder 701, multiple fixed rods 701, and multiple balls 703. The multiple fixed rods 701 are spaced apart on the support frame, and the multiple balls 703 are movably distributed on the upper ends of the multiple fixed rods 701, and the multiple balls 703 are at the same horizontal height, forming the main body of the support platform 7, namely the ball platform. The fixed rods 701 are spaced apart from the bobbin 601, and the multi-point ball platform can slide and contact the photovoltaic module, avoiding scratching the photovoltaic module and ensuring product quality.

[0030] In this embodiment, there are two support platforms 7, which are arranged along the laying direction of the production line 6. The arrangement of the two support platforms 7 can improve the stability of the all-in-one machine.

[0031] When the workpiece arrives at the transfer station 4, the lifting cylinder 701 raises the ball bearing platform to ensure the stability of the photovoltaic module. The robotic arm 501 then grabs the workpiece and assembles it in the designated position on the photovoltaic module. After completion, the lifting cylinder 701 lowers the ball bearing platform, and the assembly line 6 outputs the assembled photovoltaic module from the integrated machine. The assembled photovoltaic module is then transferred to the next workstation.

[0032] This technical solution, through the setting of a layout mechanism, a busbar welding mechanism, a conveying mechanism, a transfer station, a stacking mechanism, an assembly line, and a support platform, with the transfer station connecting the conveying mechanism and the stacking mechanism, enables this integrated machine to have the functions of battery string input, layout positioning, welding, assembly, and photovoltaic module output. At the same time, the battery string layout, stacking welding, and assembly processes are also optimized, improving the production efficiency of photovoltaic modules.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
