[0101] Preparation before work: shrink and fold the artificial platform 4 to one side, and move the inner and outer cavity hook reinforcement installation equipment to the bottom of the platform.
[0102] Hook bar loading: The hook bar material rack 7 loaded with hook bars is transported to the outer cavity platform 3 where the hook bar material rack is fixed and fixed.
[0103] Grid recognition: The feeding sliding platform 9 of the outer cavity platform 3 rises to the bottom height of the area to be installed, and the machine vision equipment of the automatic feeding robot 8 begins to scan the area on the steel bar component 2 where the hook bars are to be installed, and identifies the steel bar grid composed of the main bars and stirrups. The machine vision scans a certain area in turn. After each scan, the control system can automatically calculate the insertion positioning point position of the hook bars in the scanning area.
[0104] Hook bar feeding: The automatic feeding manipulator 8 on the hook bar feeding mechanism moves to the material rack, and the hook bar rack 7 begins to discharge and pick up the material. When the automatic feeding manipulator 8 grabs the hook bar, it grabs the hook bar and moves the hook bar clamping arm 14 of the automatic feeding manipulator 8 to the steel mesh to be threaded with the hook bar.
[0105] Move to the insertion point and insert the straight end of the hook bar from the mesh of the outer cavity steel bar component into the mesh of the steel bar component. When feeding the hook bar, due to its long length, multiple clamping jaws need to cooperate. The hook bar clamping arm 14 is pushed by the feeding electric push rod 12 to penetrate the steel bar component mesh.
[0106] Positioning of hook bars: Before the hook bars are inserted into the component, the machine vision on the bending mechanism scans the mesh of the inner cavity steel bar component and locates the position of the hook bars to be installed according to the program calculation. Wait for the hook bars to be inserted. When the clamping end of the feeding mechanism is close to the component, the opening receiving mechanism on the bending mechanism extends into the mesh and prepares to receive the material. At this time, the straight end is close to the opening on the bending device 23, and the hook bar is clamped by the hook bar clamping seat 24 along the opening. At this time, the hook bar has a hook part at the tail end, and the elbow has been inserted into the mesh, so that the hook part of the hook bar is placed against the stirrup of the component.
[0107] Hook bar connection: After the hook bar is inserted into the opening of the bending mechanism, it follows the stirrup guide groove and the tail enters the slot of the bending device 23, and the bending device 23 bends the hook bar.
[0108] Automatic bending: After the bending device 23 is engaged at the end of the hook bar to be bent, it will bend the end of the hook bar 90 degrees and attach it to the main bar. Then the hook bar, the bent part and the stirrup are immediately spot welded together.
[0109] Shift: After the hook bar end is spot welded, the feed mechanism moves to the next grid to feed the hook bar. When the hook bar enters the slot of the bending mechanism and is clamped, the feed mechanism begins spot welding. After spot welding is complete, the feed mechanism moves to the next grid. The feed mechanism and bending mechanism operate asynchronously.
[0110] Hook bar loading: When the hook bars on the hook bar rack are installed, the bending mechanism moves to the area where the next hook bar is to be installed. The feeding mechanism descends to the bottom with the platform and starts loading the next set of hook bars.
[0111] Repeat the above steps until all the hook bars in the area are installed. Industrial Applicability
