Nut conveying and welding device

The utility model relates to the technical field of welding, in particular to a nut conveying and welding device which is characterized in that nuts are screened and conveyed through a vibration discand conveyed into a conveying channel through a screening channel, an adjusting mechanism is located at the joint of the conveying channel and the screening channel, and the nuts with the non-horizontal nut orientation are adjusted into the horizontal orientation through an L-shaped adjusting rod. Only the nut in the horizontal direction is limited to pass through through a limiting edge on the conveying channel; securing correct orientation of a nut, a workpiece is inserted into the positioning pin; starting hydraulic cylinder, the connecting rod drives the spot welding machine to move downwards; meanwhile, the pressing rod moves downwards; the material channel is pressed by the pressing rod; the blocking piece is inserted into the material containing channel along a blocking piece notchto block a subsequent nut,
