[0018] Referring to the accompanying drawings, a wire knotting, cutting, and pressing mechanism includes a mounting plate 1 and a binding robot 2. The mechanism is characterized by: a linear module 3 fixedly mounted at the bottom of the mounting plate 1; a support plate 9 fixedly mounted at the bottom of the linear module 3; a linear guide rail 4 fitted to the side of the support plate 9; a vertical plate 5 fitted onto the linear guide rail 4; a mounting frame 6 fixedly mounted at the bottom of the vertical plate 5; a first stepper motor 7 fixedly mounted at the top of the vertical plate 5; the first stepper motor 7 being connected to the mounting frame 6 via a transmission; a wire spool 8 rotatably mounted near the top of the side of the mounting frame 6; the binding robot 2 fixedly mounted near the bottom of the side of the mounting frame 6; and an electric push rod 11 fixedly mounted near the bottom of the other side of the support plate 9.
[0019] The linear module 3 includes a first guide rail 301, a first slider 302, and a first drive motor 303. The bottom of the first guide rail 301 is provided with a first groove, and the first slider 302 is slidably connected along the groove. A first lead screw is rotatably provided inside the first guide rail 301. The first lead screw is threadedly connected to the first slider 302 and is driven by the first drive motor 303. The first drive motor 303 is fixedly provided on the outside of the first guide rail 301.
[0020] A support plate 9 is fixedly installed at the bottom of the first slider 302. The linear guide rail 4 includes a second guide rail 401, a second slider 402, and a second drive motor 403. The top of the second guide rail 401 is fixedly connected to the support plate 9. A first groove is opened at the bottom of the second guide rail 401. The second slider 402 is slidably connected along the first groove. A second lead screw is rotatably installed inside the second guide rail 401. The second lead screw is threadedly connected to the second slider 402. The second lead screw is drively connected to the second drive motor 403. The second drive motor 403 is fixedly installed on the outside of the second guide rail 401. The upright plate 5 is fixedly installed on the side of the second slider 402.
[0021] The mounting frame 6 is rotatably mounted on a rotating shaft 10, and the silk reel 8 is sleeved on the rotating shaft 10. A through hole is provided at the bottom of the mounting frame 6, and the through hole is located at the top of the binding robot 2.
[0022] A connecting plate is fixedly installed on the side of the support plate 9 near the bottom, and the electric push rod 11 is fixedly installed on the side of the support plate 9.
[0023] When using this device, the mounting plate 1 is securely assembled onto the corresponding position of the pre-set frame or work platform on the production line using suitable fasteners (such as bolts), ensuring that the entire mechanism is firmly installed and that there is no loosening or interference among the components. Connect the power and control circuits to the linear module 3, linear guide rail 4, electric actuator 11, first stepper motor 7, binding robot 2, etc.
[0024] The coiled steel wire to be processed is installed on the wire spool 8, so that the outer winding state of the steel wire is adapted. It rotates smoothly through the rotating shaft 10, and the end of the steel wire is pulled to the initial position where the binding robot 2 can grasp and operate (generally through the through hole at the bottom of the mounting frame 6 and placed in the working area of the binding robot 2). Through the control system, the motion parameters (such as stroke, speed, positioning accuracy, etc.) of the linear module 3 and the linear guide rail 4, as well as the rotation angle, speed and other parameters of the first stepper motor 7, and the action logic of the binding robot 2 (grabbing, knotting, cutting and other process sequences) are set, so that each component of the mechanism returns to the initial standby position: the first slider 302 of the linear module 3 is at the appropriate initial end of the first guide rail 301, the second slider 402 of the linear guide rail 4 is at the corresponding initial position of the second guide rail 401, and the wire spool 8, binding robot 2, etc. are in the ready-to-work posture.
[0025] When the workpiece to be processed on the production line arrives at the designated processing station, the control system issues a command, and the linear module 3 starts: the first drive motor 303 runs, driving the first lead screw to rotate, causing the first slider 302 to slide along the first groove of the first guide rail 301. Through the bottom support plate 9, it drives the linear guide rail 4 and subsequent connected components such as the upright plate 5 and mounting bracket 6 to move along the length direction of the linear module 3, realizing the coarse positioning of the mechanism in this direction, approaching or aligning with the target working area of the workpiece to be processed. Then, the linear guide rail 4 moves: the second drive motor 403 runs, driving the second lead screw to rotate, causing the second slider 402 to slide along the first groove of the second guide rail 401, driving the upright plate 5, mounting bracket 6, etc. to move along the length direction of the linear guide rail 4, performing more precise position adjustments, so that the binding robot 2, wire spool 8, etc. can accurately reach the specific position of the workpiece where wire knotting, cutting, and pressing are required;
[0026] After the position is adjusted, the first stepper motor 7 starts, driving the mounting frame 6, wire spool 8, and binding robot 2 to rotate around the corresponding axis by a certain angle, so that the working angle of the steel wire matches the requirements of the workpiece. Then, the binding robot 2 moves according to the preset program, grabs the end of the steel wire released by the wire spool 8, and performs the winding and knotting operations of the steel wire according to the workpiece's steel wire knotting, cutting, and pressing process requirements, fixing the steel wire in the designated position of the workpiece. After knotting is completed, the binding robot 2 performs the cutting action to cut off the excess length of steel wire. The electric push rod 11 is in the retracted state during binding. After the binding robot 2 is retracted after binding is completed, the push rod at the front end of the electric push rod 11 extends to flatten the vertical binding knot, preventing the binding knot from protruding from the surface of the box girder after concrete is poured.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
