Among them, the frame 10 is arranged in a frame structure. The feeding device 20 is fixedly installed on the frame 10, and the feeding device 20 is located at the feeding end of the frame 10 and is used for arranging and placing the floor slabs and reinforcement bars to be welded. The positioning and conveying device 30 is fixedly installed on the frame 10, and the input end of the positioning and conveying device 30 is adjacent to the output end of the feeding device 20. The moving and adjusting device 40 is fixedly installed on the positioning and conveying device 30; it is fixedly installed on the moving end of the moving and adjusting device 40, and the welding device 50 is located above the floor slabs and reinforcement bars in the process of conveying.

[0044] The automatic welding and painting equipment for the floor slab reinforcing rib square pipe in the present invention is assembled by a frame 10, a feeding device 20, a positioning and conveying device 30, a moving and adjusting device 40, a welding device 50 and a painting device 60. Among them, the feeding device 20 is used to initially position and feed the floor slab and the reinforcing ribs about to enter the equipment. The positioning and conveying device 30 is used to fixedly convey the reinforcing ribs to be welded on the floor slab in a relative position, ensuring real-time conveying while keeping the relative position of the reinforcing ribs and the floor slab unchanged during the conveying process. The welding device 50 is used to weld between the positioned and conveyed floor slab and reinforcing ribs. The painting device 60 paints and covers the welding positions of the floor slab and the reinforcing ribs after welding. The moving and adjusting device 40 is used to synchronously move the welding device 50 and the painting device 60. During assembly, the feeding device 20 and the positioning and conveying device 30 are both fixedly installed on the frame 10. The feeding device 20 is capable of initially positioning, arranging and conveying the floor slab and the reinforcing ribs, ensuring that the relative position of the floor slab and the reinforcing ribs remains unchanged during the conveying process after entering the feeding device 20, which is convenient for subsequent operations. The moving and adjusting device 40 is fixedly installed on the positioning and conveying device 30. Then, the welding device 50 and the painting device 60 are respectively fixedly installed on the two moving ends of the moving and adjusting device 40. The two moving ends of the moving and adjusting device 40 move synchronously, realizing that one moving device drives two workstations to operate synchronously. The moving path of the moving end of the moving and adjusting device 40 is perpendicular to the material conveying path. Moreover, the feeding device 20 is located on one side of the feeding end of the frame 10, and one end of the feeding device 20 extends outward towards the feeding side of the frame 10 for convenient feeding. The feeding end of the positioning and conveying device 30 is adjacent to the discharging end of the feeding device 20. During operation, the floor slab and the reinforcing ribs are arranged by the feeding device 20 and then conveyed into the positioning and conveying device 30. The moving and adjusting device 40 drives the welding device 50 and the painting device 60 to move synchronously. The conveyed floor slab and reinforcing ribs enter the positioning and conveying device 30 and successively pass through the welding device 50 and the painting device 60, welding between the floor slab and the reinforcing ribs respectively, and spraying and covering the welding points. After welding and painting, the finished product is output. Through the above structural settings, it can be realized to automatically complete the welding process of the reinforcing ribs of the floor slab. At the same time, according to the processing requirements, the feeding device 20 and the positioning and conveying device 30 are adjusted to adapt to the welding processing of different models and different quantities of reinforcing ribs. Through the above structural settings, the welding processing of the reinforcing ribs of different specifications, models and quantities on the floor slab is realized.

[0045] In another embodiment of the present invention, as Figures 1 to 3As shown, the feeding device 20 includes a base 21, a guiding bracket 22 and two limiting plates 23. The limiting plates 23 are used to plan the path for the floor slab transportation. The guiding bracket 22 divides the area between the two transportation paths. There is a gap between the guiding 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 guiding bracket 22 and the limiting plates 23 are both fixedly installed on the base 21. The two limiting plates 23 are arranged relatively parallel. Arcuate surfaces are provided at both ends of the opposite sides of the two limiting plates 23, which play a certain guiding role in the feeding of the floor slab. The floor slab in transportation is located between the two limiting plates 23. The guiding bracket 22 is arranged above the two limiting plates 23 in a spanning manner and is used to guide the arrangement and movement of the square tubes. The guiding bracket 22 can convey and position the reinforcing ribs to be welded on the floor slab, ensuring that the relative positions between the respective reinforcing ribs and the floor slab remain fixed during transportation.

[0046] In another embodiment of the present invention, as Figures 1 to 3 shown, the guiding bracket 22 includes a plurality of mounting frames 221 and a plurality of partition plates 222. The partition plates 222 are adjusted in terms of spacing and quantity according to processing requirements. The mounting frames 221 are fixedly installed on the base 21.

Each partition plate 222 is fixedly installed on the mounting frame 221, and the partition plates 222 are arranged parallel and spaced from each other. Each partition plate 222 is located above the base 21. One end of the two non-adjacent sides of the partition plate 222 opposite to the feeding direction is arranged with arcuate surfaces approaching each other, which plays a role in guiding and inputting the reinforcing ribs entering between the two partition plates 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 conveying of the floor slab and each reinforcing rib between the entire positioning and conveying device 30, and ensure the smoothness of the conveying traction. The fixed frame 31 and the driving device 32 are both installed 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 installed 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 in sequence along the conveying direction. The welding device 50 is located between the first traction wheel set 33 and the second traction wheel set 34. Adjustable gaps are provided on the first traction wheel set 33 corresponding to the reinforcing ribs during processing, ensuring that the relative positions between the respective reinforcing ribs and the floor slab do not change when welding processing is not carried out, thus affecting subsequent welding processing. The second traction wheel set 34 then assists in pulling the floor slab and the reinforcing ribs after welding to continue moving. The painting device 60 is located between the second traction wheel set 34 and the third traction wheel set 35. The second traction wheel set 34 pulls the processed parts after welding towards the third traction wheel set 35, and the painting device 60 sprays and covers the floor slab and the reinforcing ribs that have been welded and are located between the first traction wheel set 33 and the second traction wheel set 34.

[0048] A lifting and positioning device for blocking the end of the floor slab to be processed is provided between the first traction wheel set 33 and the second traction wheel set 34. When the end of the floor slab enters the first traction wheel set 33, the lifting and positioning device rises, and the end of the floor slab abuts against it, restricting the movement of the floor slab and positioning and confirming the position of the first welding point on the floor slab. After welding is completed, the lifting and positioning device descends, restoring the directional movement path of the floor slab. The first traction wheel set 32 pushes the floor slab to move, completing subsequent welding until the floor slab is taken out after welding is completed. Repeat this operation to complete the processing of different floor slabs.
