The device 60 moves synchronously, and the floor slab and reinforcing ribs being transported enter the positioning conveying device 30 and pass through the welding device 50 and the painting device 60 in sequence. The floor slab and reinforcing ribs are welded together, and the weld points are covered with paint. After welding and painting are completed, the finished product is output. Through the above structural settings, the welding of reinforcing ribs on the floor slab can be completed automatically. At the same time, the feeding device 20 and the positioning conveying device 30 can be adjusted according to the processing requirements to adapt to the welding processing of different models and quantities of reinforcing ribs. Through the above structural settings, the welding processing of reinforcing ribs of different specifications, models and quantities on the floor slab can be completed.

[0041] In another embodiment of this utility model, such as Figures 1-3As shown, the feeding device 20 includes a base 21, a guide bracket 22, and two limiting plates 23. The limiting plates 23 are used to plan the path for conveying the floor slab. The guide bracket 22 divides the area between the two conveying paths, and a gap is left between the guide bracket 22 and the upper surface of the base 21 for the floor slab to pass through. The base 21 is fixedly installed on the frame 10. The guide bracket 22 and the limiting plates 23 are both fixedly installed on the base 21. The two limiting plates 23 are arranged relatively parallel. Both ends of the opposite sides of the two limiting plates 23 are provided with arc-shaped surfaces, which play a certain guiding role in the feeding of the floor slab. The floor slab being conveyed is located between the two limiting plates 23. The guide bracket 22 is set across the two limiting plates 23 and is used to guide the square tube arrangement and movement. The guide bracket 22 can convey and position the reinforcing ribs to be welded to the floor slab, ensuring that the relative position between each reinforcing rib and the floor slab remains fixed during the conveying process.

[0042] In another embodiment of this utility model, such as Figures 1-3 As shown, the guide bracket 22 includes several mounting brackets 221 and several partitions 222.

The first traction wheel set 33, the second traction wheel set 34, and the third traction wheel set 35 ensure the stability of the floor slab and each reinforcing rib during the entire positioning and conveying device 30, and ensure smooth conveying traction. The fixed frame 31 and the drive unit 32 are both mounted on the frame 10. The first traction wheel set 33, the second traction wheel set 34, and the third traction wheel set 35 are all mounted on the fixed frame 31, and the first traction wheel set 33, the second traction wheel set 34, and the third traction wheel set 35 are arranged sequentially along the conveying direction. The welding device 50 is located at the first traction wheel set 35. Between the first traction wheel group 33 and the second traction wheel group 34, the first traction wheel group 33 is provided with adjustable gaps corresponding to the reinforcing ribs during processing. This ensures that the relative positions of each reinforcing rib and the floor panel do not change when welding is not performed, thus affecting subsequent welding processing. The second traction wheel group 34 then assists in pulling the floor panel and reinforcing ribs after welding to continue moving. The painting device 60 is located between the second traction wheel group 34 and the third traction wheel group 35. The second traction wheel group 34 pulls the processed parts after welding towards the third traction wheel group 35.

[0044] A lifting and positioning device is provided between the first traction wheel group 33 and the second traction wheel group 34 to block the end of the floor panel to be processed. When the end of the floor panel enters the first traction wheel group 33, the lifting and positioning device rises, and the end of the floor panel comes into contact with it, restricting the movement of the floor panel. The position of the first welding point on the floor panel is located and confirmed. After the welding is completed, the lifting and positioning device is lowered, restoring the directional movement path of the floor panel. The first traction wheel group 32 pushes the floor panel to move and completes the subsequent welding. The floor panel is removed after welding is completed. This operation is repeated to complete the processing of different floor panels.

The separating roller shaft 332 is located above the first traction wheel 333. The two ends of the separating roller shaft 332 are respectively rotatably connected to the two first movable blocks. The two lifting cylinders drive the two first movable blocks to move up and down, thereby changing the position of the separating roller shaft 332 and completing the lifting adjustment of the separating roller shaft 332, thereby changing the distance between the separating roller shaft 332 and the first traction wheel 333.

[0046] The second traction wheel group 34 and the third traction wheel group 35 each include two second lifting devices 43 and two second traction wheels. The two second lifting devices 43 are fixedly installed on the fixed frame 31. Both ends of the two second traction wheels are rotatably installed on the fixed frame 31.

When the driving device drives the first traction wheel 32 to rotate 333, the first auxiliary gear 311 and the second auxiliary gear 312 synchronously drive the two second traction wheels to rotate. Through the steering action of the first auxiliary gear 311 and the second auxiliary gear 312, the two second traction wheels rotate synchronously and in the same direction as the first traction wheel 333.

[0048] The second lifting device 43 includes an adjusting rod, a second mounting plate, and a second moving block. The second mounting plate is fixedly mounted on the fixed frame 31.
