After the technical scheme is adopted, the invention has the beneficial effects that:

according to the welding production line for the boundary beam connecting plate of the parking equipment, due to the fact that the assembling and welding device, the welding device and the discharging device are designed, spot welding of the boundary beam and the connecting plate is achieved through the assembling and welding device, welding of the boundary beam and the connecting plate is achieved through the welding device, and finally the welded boundary beam is discharged through the discharging device; because the assembly welding device is provided with the first positioning piece, the first jacking piece driven by the first linear driving device, the first side positioning seat, the second side positioning seat and the first pressing seat driven by the second linear driving device, the first positioning surface and the first jacking piece are respectively provided with the end plate mounting hole corresponding to the first working area, and the first pressing seat is provided with the second reinforcing plate mounting hole, during assembly welding, firstly, the end plates are respectively fixed on the first positioning surface and the end plate mounting hole of the first jacking piece, the second reinforcing plate is fixed on the second reinforcing plate mounting hole of the first pressing seat, then, the edge beam is arranged in the first working area, and then, the end surface and the side surface of the edge beam are respectively pressed against the end plate and the first side positioning reference surface through the first jacking piece of the first linear driving device and the first pressing seat of the second linear driving device, the second side positioning datum plane is outwards staggered relative to the first side positioning datum plane by a distance which is equivalent to the thickness of the first reinforcing plate, so that a first reinforcing plate placing gap can be formed between the edge beam and the second side positioning seat, and after the first reinforcing plate is placed in the gap, the edge beam and the connecting plate can be subjected to spot welding, so that the edge beam and the connecting plate do not need to be positioned manually, and the welding efficiency can be improved; meanwhile, the welding production line also comprises a turnover mechanism, so that the edge beam is turned over through the turnover mechanism instead of manually turning over the edge beam, the labor intensity of workers is reduced, and the production efficiency is improved; after the edge beam is turned over, the other surface can be spot-welded. Because the welding device is provided with the second positioning piece, the second jacking piece driven by the third linear driving device, the third side positioning seat and the second pressing seat driven by the fourth linear driving device, the edge beam after spot welding is arranged in the second working area during welding, and then the end surface and the side surface of the edge beam are respectively propped against the second positioning surface and the third side positioning reference surface through the second jacking piece of the third linear driving device and the second pressing seat of the fourth linear driving device, so that the edge beam and the connecting plate can be welded, the edge beam is not required to be positioned manually, and the welding efficiency can be improved; after one side welding is finished, the turnover mechanism is used for overturning the side beam, and the other side can be welded. According to the welding production line for the boundary beam connecting plate of the parking equipment, the boundary beam and the connecting plate are not required to be positioned manually, the welding efficiency is improved, the boundary beam and the connecting plate are welded, and the welding consistency is good; need not rely on artifical edge beam to overturn, labour saving and time saving.
