Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic inverter production, and more specifically, to a bending processing device and a bending method for photovoltaic inverter profiles. Background Art

[0002] Photovoltaic inverters are inverters that can convert the variable DC voltage generated by photovoltaic (PV) solar panels into AC power at mains frequency, which can be fed back to the commercial power transmission system or used for off-grid power grids. Photovoltaic inverters are one of the important balance of systems (BOS) in photovoltaic array systems and can be used with general AC-powered equipment. Solar inverters have special functions for photovoltaic arrays, such as maximum power point tracking and islanding protection. In the production process of photovoltaic inverters, the housing door panels need to be bent using a bending processing device during the production process.

[0003] With regard to the above-mentioned related technologies, during the current processing and bending of the inverter housing door panels, the door panels are usually manually held and placed in a bending machine. The driving facilities on the device drive the bending mold to approach and perform the bending operation. After the bending is completed, the staff replaces the door panels and bends them again. During the bending process, multiple batches of inverter door panels are usually encountered, and the number of door panels in each batch is large. After bending, the staff need to sort them out, which makes the manual operation burden of the staff heavy. At present, some small number of bending processing devices are processed by CNC robotic arms. Although this method can reduce the burden on the staff, coupled with a large number of driving facilities on the bending device, the cost of the device will increase sharply, which is not conducive to the popularization of the device.
