Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding processing, in particular to a photovoltaic device welding device. BACKGROUND

[0002] As a core structural component of photovoltaic modules, the frame of the photovoltaic panel bears the key role of support, protection and installation adaptation, can stably fix the core laminated parts such as photovoltaic glass, battery pieces and back plates, avoid deformation or interlayer peeling of the module due to external force during transportation, installation and outdoor operation, protect the integrity of the module structure, ensure that the photovoltaic panel maintains stability and meets the best inclination requirement in different scenarios such as roof and ground, improves the power generation efficiency, and the rounded treatment of the corners of the frame can also reduce the risk of safe bumping during installation and operation.

[0003] However, unintended deformation may occur before welding the frame of the photovoltaic panel. From the production end, the frame is mostly made of aluminum alloy extrusion, if the extrusion process parameters such as temperature, pressure and cooling speed are unstable, or if the stress is uneven during subsequent cutting and punching, it may cause the frame to appear slight linear bending or local warping. From the transportation and storage end, if the frame is stacked too high, causing local overload, or if it encounters bumps and collisions during transportation, the frame may also be deformed due to external impact. This deformation will destroy the required interface close-fitting condition for welding, causing uneven weld gap, prone to problems such as virtual welding and incomplete fusion, and may also cause the welding path to deviate, causing short circuit hazards due to accidental contact with the functional area of the panel. Meanwhile, uneven welding will leave residual initial internal stress, which is prone to cause weld cracks and fractures under the action of outdoor temperature changes and other factors, and cannot form a continuous sealing surface, damaging the IP protection level of the equipment, allowing water vapor and impurities to enter and corrode the components, ultimately affecting the welding quality and long-term reliability of the equipment.

When the gap between the two flat photovoltaic plate materials needs to be adjusted during the detection process, the rolling motor 44 is started at this time. The output end of the rolling motor 44 drives the rolling cylinder 43 to rotate, the rolling cylinder 43 drives the rolling track 45 to slide outside the vacuum pump table 42, and the photovoltaic plate material on the rolling track 45 is moved to adjust the gap. When the heights of the welding positions of the two photovoltaic plate materials are inconsistent, the two first telescopic rods 37 and the two second telescopic rods 39 are started to drive the driving frame 41 to move upward, so that the welding positions of the two photovoltaic plate materials are adjusted to the same height. When the two angle sensors 29 detect that the welding positions of the two photovoltaic plate materials are not flat, the two first telescopic rods 37 and the two second telescopic rods 39 are started to adjust the parallelism of the welding positions of the two photovoltaic plate materials. In the process of rotating the driving frame 41, the second telescopic rod 39 slides in the sliding sleeve 38, and the limiting tension spring 40 is stretched at this time, so that the first telescopic rod 37 and the second telescopic rod 39 are not stuck during the rotation of the driving frame 41.
