The upper and lower layers of longitudinal wires are sent into the mesh welding machine through the longitudinal wire feeding mechanism, and then the upper and lower layers of transverse wires are respectively sent into the mesh welding machine through the transverse wire feeding mechanism to be welded into an upper mesh and a lower mesh; the welded upper mesh and lower mesh are sent into the mesh channel of the vertical connecting rib feeding and welding mechanism; the upper mesh and the lower mesh are fixed by the mesh positioning clamp; the reinforcing bars on the connecting rib pay-off reel pass through the feeding guiding mechanism, the connecting rib feeding mechanism, and the connecting rib straightening mechanism, and the lower end part is inserted below the reinforcing bar cutting mechanism; the ejector rod of the push cylinder retracts, driving the connecting rib gripper to retract, so that the connecting rib gripper clamps the connecting rib, and then the reinforcing bar cutting mechanism cuts off the connecting rib; the ejector rod of the push cylinder moves forward, driving the connecting rib gripper to move forward, and the connecting rib gripper sends the connecting rib between the upper mesh and the lower mesh; the connecting rib welding mechanism welds both ends of the connecting rib to the upper mesh and the lower mesh, and the connecting rib welds the upper mesh and the lower mesh into a cage; under the thrust of the longitudinal wire feeding mechanism, the cage moves forward; when the cage advances to a set length, the cage is cut off by the mesh cutting mechanism; the cut-off cage drops onto the mesh dropping mechanism; the above steps are repeated until the stacking height of the cages reaches the requirement, the stacked mesh frame is removed, and stacking starts again until welding is completed, saving space, having high welding quality, and being able to complete industrial production, greatly improving production efficiency;Second, since the connecting rib welding mechanism includes a welding frame body, a first welding head seat with a first welding head, and a second welding head seat with a second welding head, a lifting air cylinder with a push rod is arranged above the welding frame body. A pressing block is arranged below the push rod. A first chain flap and a second chain flap are connected to the pressing block through a limiting rotating shaft. The first chain flap and the second chain flap are connected to the upper ends of the first welding head seat and the second welding head seat through a limiting rotating shaft.

The inner ends of the third chain flap and the fourth chain flap close to the inside tilt obliquely upward, and the outer ends of the fifth chain flap and the sixth chain flap close to the outside tilt obliquely upward. The first welding head and the second welding head open to the maximum distance. When the push rod of the lifting air cylinder is pressed downward, the pressing block drives the first chain flap, the second chain flap, the first welding head seat, and the second welding head seat to gradually move downward. The inner ends of the third chain flap and the fourth chain flap gradually reach the horizontal position from the position of tilting obliquely upward. The outer ends of the fifth chain flap and the sixth chain flap gradually reach the horizontal position from the position of tilting obliquely upward.

The first welding head and the second welding head open to the maximum distance. When the first welding head and the second welding head reach the joint of the horizontal wire and the vertical wire, that is, before welding starts, the surfaces of the first welding head and the second welding head are in a parallel position. At this time, the first welding head and the second welding head are squeezing the horizontal wire and the vertical wire directly, which will not cause the displacement and deformation of the solder joints, and the welding strength is high. The first welding head and the second welding head reach the welding position by swinging, occupying a small space and being suitable for being completed on the production line. Thirdly, since the first welding head seat and the second welding head seat are in an inverted "L" shape, the first welding head seat and the second welding head seat are arranged oppositely.
