[0102] In one embodiment of the present application, the top of the stirrup is clamped by the opposite movement of the left clamp block 46 and the right clamp block 47, and the clamping of the stirrup is loosened by the opposite movement of the left clamp block 46 and the right clamp block 47; thereby, the stirrup is straightened when the stirrup and the longitudinal reinforcement are penetrated relative to each other and welded.

[0103] In this embodiment, a plurality of cylinders may be provided on the straightening frame 41 , and the output ends of the plurality of cylinders are connected to the straightening base plate 42 to drive the straightening base plate 42 to move in the vertical direction.

[0104] A plurality of jacking mechanisms 5 are provided at the bottom of a pair of conveying guide rails, and the jacking mechanisms 5 are used to temporarily support the stirrup clamps 3 .

[0105] A pressing block 29 is provided on the upper portion of the guide wheel 25 . The pressing block 29 is controlled by a cylinder to move up and down to press the longitudinal ribs on the guide wheel 25 .

[0106] In this embodiment, five longitudinal reinforcement support units 2 are arranged on the conveying track 1. The longitudinal reinforcement support unit 2 located at the front end is not provided with a straightening mechanism 4, and the other four longitudinal reinforcement support units 2 are all provided with a straightening mechanism 4. In addition, the base plates and guide wheels 25 on the front end longitudinal reinforcement support unit 2 are arranged backward, and the front end longitudinal reinforcement support unit 2 is similar to dragging the rectangular steel frame forward.

[0107] The rectangular steel frame automatic assembly device includes the following steps when in use:

[0108] Step 1: Multiple jacking mechanisms 5 are raised simultaneously, and the stirrup angle on one side of the conveying guide rail is transferred to the jacking mechanism 5, and the jacking mechanism 5 temporarily supports the stirrup clamp 3;

[0109] In step 2, the plurality of longitudinal reinforcement support units 2 are moved along the conveying guide rail so that the longitudinal reinforcement support units 2 are located outside the stirrup clamp 3; when the longitudinal reinforcement support units 2 encounter the jacking mechanism 5, the jacking mechanism 5 is lowered to allow the longitudinal reinforcement support units 2 to pass through; after the plurality of longitudinal reinforcement support units 2 are moved into position, the plurality of longitudinal reinforcement support units 2 are evenly distributed along the extension direction of the stirrup clamp 3, thereby making it easier for the longitudinal reinforcement support units 2 to more evenly support the longitudinal reinforcement later;

[0110] Step 3: Adjust the relative positions of the bottom frame 21, the top frame 24, the left frame 22, and the right frame 23 so that the positions of the bottom frame 21, the top frame 24, the left frame 22, and the right frame 23 are compatible with the size of the stirrups;

[0111] Step 4: Control the multiple lifting mechanisms 5 to descend simultaneously, so that the stirrup fixture 3 falls on the bottom base plate 211, and fine-tune the positions of the bottom base plate 211, the top base plate 241, the left base plate 221, and the right base plate 231 relative to the stirrups;

[0112] At the same time, the spacing between the V-shaped folding link 28 components on the bottom base plate 211, the top base plate 241, the left base plate 221, and the right base plate 231 is adjusted so that the guide wheels 25 on the bottom base plate 211, the top base plate 241, the left base plate 221, and the right base plate 231 can correspond to the positions where the stirrups need to be installed with the longitudinal reinforcement;

[0113] In step 5, the straightening base plate 42 in the straightening mechanism 4 is lowered, and the left clamping block 46 and the right clamping block 47 are controlled to move relative to each other, clamping the top of the stirrup to keep the stirrup in a vertical state; in this embodiment, since the stirrup mesh is large, the straightening mechanism 4 is provided to clamp the top of the straightening stirrup to prevent the stirrup from tilting and bending, thereby ensuring the precise alignment of the stirrup and the longitudinal reinforcement and precise welding and fixation.

[0114] Step 6: Insert the longitudinal reinforcement into the guide wheel 25 of each longitudinal reinforcement support unit 2 in sequence. After the longitudinal reinforcement is in place, the upper pressing block 29 of the guide wheel 25 presses the longitudinal reinforcement downward;

[0115] Step 7: First, weld the stirrups and longitudinal reinforcement between the first longitudinal reinforcement support unit 2 and the second longitudinal reinforcement support unit 2. After welding is completed, the straightening mechanism 4 in the second longitudinal reinforcement support unit 2 cancels the clamping stirrups and moves upward. At the same time, the bottom base plate 211, the top base plate 241, the left base plate 221, and the right base plate 231 on the second longitudinal reinforcement support unit 2 all drive their respective guide wheels 25 to move outward from the stirrups, so that the guide wheels 25 are out of the range of the stirrups.

[0116] Step 8: The second longitudinal reinforcement support unit 2 remains different. While the other longitudinal reinforcement support units 2 drive the stirrup clamp 3 to move forward by the length of the straightening clamp, the straightening base plate 42 in the straightening mechanism 4 of the second longitudinal reinforcement support unit 2 is lowered, and the left clamping block 46 and the right clamping block 47 are controlled to move relative to each other to clamp the top of the stirrup. The stirrup and the longitudinal reinforcement within the clamping range of the straightening mechanism 4 of the second longitudinal reinforcement support unit 2 are then precisely welded together.

[0117] Step 9, repeat step 8 until all stirrups and longitudinal reinforcements are welded together; when the longitudinal reinforcement support unit 2 behind the second longitudinal reinforcement support unit 2 moves to interfere with it, the straightening mechanism 4 in the interfering longitudinal reinforcement support unit 2 will cancel the clamping stirrups and move upward, and at the same time, the bottom base plate 211, top base plate 241, left base plate 221 and right base plate 231 on the longitudinal reinforcement support unit 2 will drive their respective guide wheels 25 to move outside the stirrups, so that the guide wheels 25 exit the stirrup range.

[0118] It will be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0119] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
