Description

Technical Field

[0001] The present invention relates to the field of welding technology, and in particular to an automatic welding device for processing photovoltaic modules. Background Art

[0002] Photovoltaic modules are core components of solar power generation systems, and the quality of their welding directly affects the module's electrical conductivity, mechanical strength, and service life. Currently, string welding (connecting cells in series via solder ribbons) is a key step in the photovoltaic module welding process. Mainstream equipment includes fully automatic stringing machines and semi-automatic welding devices. Conventional welding devices commonly suffer from the following technical bottlenecks:

[0003] Most equipment requires manual placement of cell strips or solder ribbons in batches, and cannot seamlessly connect with upstream production lines (such as cell sorting and typesetting equipment), resulting in limited welding efficiency (such as frequent shutdowns waiting for loading). Moreover, when manually placing the strips, it is easy for the strips to shift or stack due to operational errors, affecting the subsequent positioning accuracy and even causing defects such as welding misalignment and cold solder joints. In traditional devices, the positioning of cell strips or solder ribbons usually relies on manual adjustment of fixtures, which is time-consuming and labor-intensive and difficult to ensure consistency. Although some equipment has mechanical positioning functions, the fixing mechanism must be manually triggered, and the full "loading-positioning-fixing" process cannot be automated. After welding is completed, manual operation is still required to release the workpiece, which increases labor intensity and may cause damage to components due to uneven disassembly force.

[0004] After welding, the components need to be manually transferred to a turning table or cutting equipment, which is prone to bumps and damage; the cutting process is often independent of the welding device, resulting in long logistics routes and waste of production capacity; welding quality inspection (such as appearance defects and welding strength) mostly relies on manual visual inspection or offline spot checks, and it is impossible to feedback data in real time during the welding process, making it difficult to achieve online elimination of defective components, affecting yield control.

[0005] In response to the above problems, this invention document proposes an automatic welding device for photovoltaic module processing. Summary of the Invention

A passive feeding component 205 is provided on the upper belt conveyor component 201. The passive feeding component 205 includes two limiting cylinders 2051. The two limiting cylinders 2051 are rotatably mounted on the two upper mounting brackets 2011 through bearings.

[0046] Example 3: Reference Figure 1-Figure 2 and Figure 4 An automatic welding device for photovoltaic module processing includes a post-welding processing mechanism 100, which includes a processing base 101. A lower belt conveyor assembly 102 is provided on the processing base 101. Photovoltaic module cutting assemblies 103 are provided on both the upper and lower sides of the lower belt conveyor assembly 102.

[0047] The photovoltaic module welding mechanism 200 includes an upper belt conveyor assembly 201, a welding assembly 202 is arranged above the upper belt conveyor assembly 201, two inclined panels 204 are connected to the welding assembly 202, and a plurality of automatic positioning assemblies 206 are provided on the upper belt conveyor assembly 201. After the automatic positioning assembly 206 passes the inclined surface of the inclined panel 204, it automatically rotates and positions the photovoltaic module. A passive feeding assembly 205 is provided on the upper belt conveyor assembly 201. The photovoltaic module is transported by the upper belt conveyor assembly 201, so that the passive feeding assembly 205 follows the movement, thereby automatically discharging the material, and the welded photovoltaic module is transported to the bottom. When it falls off in a suspended state, it proves that there is a problem of loose welding.

[0048] In this embodiment: the photovoltaic components are transported by the upper belt conveyor component 201, so that the passive feeding component 205 follows the conveyor belt 2055, thereby facilitating direct welding processing through the welding component 202, and the photovoltaic components are transported downward after welding, so that the photovoltaic components fall between the upper belt conveyor component 201 and the lower belt conveyor component 102 and are in a suspended state, so that it can be detected whether the photovoltaic components are welded firmly. After the detection, the photovoltaic components are directly transferred to the lower belt conveyor component 102, and then directly cut by the photovoltaic component cutting component 103, thereby quickly processing the photovoltaic components. This method can detect the welding quality of the photovoltaic components in real time after the welding process is completed to ensure that each product meets the standards. Moreover, the detection and cutting links are closely connected and efficiently coordinated, which greatly shortens the processing cycle, so that the photovoltaic components can quickly complete the whole process from welding to cutting, providing a strong guarantee for the efficient production of the photovoltaic industry.

[0049] Working principle: When performing photovoltaic module welding operations, the photovoltaic modules are placed on the upper belt conveyor structure 2012, so that the upper belt conveyor structure 2012 conveys the photovoltaic modules. When the ball structure 2065 passes through the inclined surface of the inclined plate 204, the ball structure 2065 presses down the movable cylinder 2062, and the movable cylinder 2062 drives the return spring 2066 to deform, and the movable cylinder 2062 drives the ball rod 2069 to move through the outer ring structure 2063. The ball rod 2069 slides in the arc groove 20610 and rotates through the arc surface of the arc groove 20610, so that the outer ring structure 2063 drives the positioning pressure plate 2064 to rotate. The positioning pressure plate 2064 is located above the photovoltaic module. At this time, it continues to press down to position the positioning pressure plate 2064 to position the photovoltaic module. When the photovoltaic module is transported to the welding area, the welding equipment 2023 moves downward and performs the welding operation of the photovoltaic module through the material belt 2055.

[0050] After welding, the upper belt conveyor structure 2012 continues to convey the photovoltaic modules out of the welding area. At the same time, the photovoltaic modules to be welded arrive at the welding area again. During the conveying process, the material belt 2055 is released from the discharge tray 2053. The material belt 2055 is stretched along with the photovoltaic modules. The material belt 2055 continues to be accurately pressed on the photovoltaic modules by the pressing roller structure 203, ready for the welding operation.

[0051] After the welded photovoltaic components are separated from the upper belt conveyor structure 2012, the material belt 2055 connects each photovoltaic component, so that the photovoltaic components are smoothly conveyed downward. When the photovoltaic components are in a suspended state, their welding firmness can be tested, and the adhered photovoltaic components are smoothly placed on the lower belt conveyor structure 1022, so that the lower belt conveyor structure 1022 conveys the photovoltaic components and transfers them to the roller group conveyor structure 1023. When the photovoltaic components are in the cutting area, the electric push rod 1033 controls the movement of the cutting knife 1031, so that the cutting knife 1031 can cut the material belt 2055, so that the photovoltaic components are smoothly output and the cutting process is completed.

[0052] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
