[0002] In the field of prefabricated concrete buildings, cutting treatment of the joint of the mold after wall slab production is one of the important steps for subsequent construction.

[0003] The joint of the mold is a trace inevitably produced in the production process of the prefabricated concrete wall slab due to the mold structure and pouring process. The joint of the mold is generally a groove or a protrusion. The protruding joint of the mold will become a channel for rainwater or moisture to penetrate, especially for the outer wall slab, which will seriously affect the waterproof performance of the building. At this time, the joint of the mold needs to be cut.

[0004] The existing treatment method generally cuts and removes the protruding part through a cutting saw. At this time, since the concrete prefabricated wall slab has exposed steel bars, the steel bars are located at the same position as the joint of the mold.

[0022] When working, the prepared wallboard is placed into the wallboard fixing device by a gantry crane or other hoisting device, and the wallboard is fixed by the wallboard fixing device.

[0023] Then the camera 102 is used for detecting the concrete wallboard by taking pictures, recording the positions of the jointing seam and the steel bars, and judging the angle of the steel bars, so as to provide position information basis for the actions of the auxiliary manipulator 4 and the cutting manipulator 2 subsequently. The jointing seam is generally in the form of a groove or a protrusion, and the protrusion is generally in the form of a trapezoid. The present embodiment mainly cuts the protruding part, which is convenient for subsequent installation.

[0024] Then, the auxiliary manipulator 4 is actuated to move the auxiliary assembly to be sleeved on the steel bar, and then the steel bar is straightened by moving the auxiliary manipulator 4, and then the auxiliary assembly is still sleeved above the steel bar at the joint.

[0025] Then, the auxiliary assembly is actuated to polish and cut the joint, and an opening with a diameter larger than the rotating cylinder 504 is formed at the steel bar, and then the auxiliary assembly is moved out of the steel bar, and the cutting manipulator 2 is actuated to move the cutting saw 3 to the joint to cut the joint.

[0026] Since the joint is generally trapezoidal, the cutting can be performed in a way that one side cuts a part, then rotates along the steel bar to cut a semicircle, and then the other side is cut to separate the joint from the wallboard.

[0027] In short, during the work, the concrete wallboard is clamped and fixed by the wallboard fixing device, then the camera 102 detects the concrete wallboard to obtain the position information of the joint and the steel bar, then the auxiliary manipulator 4 is actuated to move the auxiliary assembly to be sleeved on the steel bar, the steel bar is straightened and kept in the sleeved state, and then the cutting manipulator 2 is actuated to move the cutting saw 3 to the joint to cut the joint.

[0028] Specifically, the steel bars without the joint below can also be straightened by the auxiliary manipulator 4.

[0029] Further, as shown in FIG. 6, the auxiliary assembly 5 is provided with a plurality of auxiliary straightening mechanisms 501, and the auxiliary straightening mechanisms 501 are arranged in a staggered manner. Figure 6 , Figure 7 , Figure 8As shown, the auxiliary assembly includes a mounting plate 501, a mounting cylinder 502, and a rotating cylinder 504, the mounting plate 501 is mounted on the auxiliary manipulator 4, the mounting cylinder 502 is fixedly mounted on the mounting plate 501, the mounting cylinder 502 is used to accommodate the passing of the steel bar, the rotating cylinder 504 is rotatably connected to the mounting plate 501, and the rotating cylinder 504 is sleeved on the mounting cylinder 502, a plurality of grinding knives 508 are annularly mounted at the bottom of the rotating cylinder 504, the grinding knives 508 can polish the joint of the steel bar at the joint of the mold, and a circular groove is polished, the bottom of the mounting cylinder 502 is threadedly connected with a sleeve 505, the inner diameter of the sleeve 505 matches the outer diameter of the steel bar, so that the sleeve 505 can be closely sleeved on the steel bar, on the one hand, when the auxiliary manipulator 4 drives the auxiliary assembly to straighten the steel bar, the sleeve 505 can better cooperate with the steel bar to ensure the straightening effect; on the other hand, when the joint of the mold is polished subsequently, the sleeve 505 can also play a certain positioning and protection role on the steel bar to prevent the steel bar from being damaged by excessive polishing of the grinding knives 508, when different diameters of steel bars need to be operated, the sleeve 505 matched with the outer diameter of the steel bar can be replaced by screwing the sleeve 505, and the applicability of the equipment is improved, the mounting plate 501 is fixedly connected with a motor 506, a gear piece 5071 is fixedly connected to the output end of the motor 506, and a tooth ring 5072 is fixedly connected in the rotating cylinder 504, and the gear piece 5071 and the tooth ring 5072 are in meshing connection.

[0030] After the concrete wallboard is photographed and detected by the camera 102, the positions of the joint of the mold and the steel bar are recorded, and the angle of the steel bar is judged.

[0031] Then the auxiliary manipulator 4 moves to drive the auxiliary assembly to move, so that the sleeve 505 in the auxiliary assembly is sleeved on the steel bar to straighten the steel bar, and then the sleeve 505 is still sleeved above the steel bar at the joint of the mold, and then the motor 506 in the auxiliary assembly is started, the motor 506 drives the rotating cylinder 504 to rotate through the gear piece 5071 and the tooth ring 5072, the grinding knives 508 at the bottom of the rotating cylinder 504 rotate to polish and cut the joint of the mold, and an aperture with a diameter larger than the rotating cylinder 504 is formed at the steel bar.

[0032] Then the sleeve 505 moves out of the steel bar upwardly, the cutting saw 3 is moved to the joint of the mold by the cutting manipulator 2 to cut the joint of the mold, since the joint of the mold is generally trapezoidal, the cutting can be performed in a mode that one side cuts a part and then rotates along the steel bar to cut a semicircle, and then the other side is cut to separate the joint of the mold from the wallboard.

[0033] Specifically, as Figure 6 , Figure 7 , Figure 8As shown, the bottom of the rotating cylinder 504 has a mounting groove, the grinding knife 508 is mounted in the mounting groove, one end of the grinding knife 508 extends out of the rotating cylinder 504, and the other end is close to the sleeve 505. The rotating cylinder 504 is threadedly connected with a mounting bolt 5091, the grinding knife 508 is threadedly connected with the mounting bolt 5091, the mounting groove provides a mounting space for the grinding knife 508, and the length of the grinding knife 508 extending out of the rotating cylinder 504 can be conveniently adjusted through the threaded connection between the mounting bolt 5091 and the grinding knife 508, so as to adapt to the polishing requirements of the die joint of different depths.

[0034] Further, as shown in Figure 8 , the mounting bolt 5091 is threadedly connected with a locking nut 5092, the locking nut 5092 is used for locking and fixing the mounting bolt 5091, the bottom of the mounting plate 501 is fixedly connected with a mounting seat 503, and the rotating cylinder 504 is rotatably connected in the mounting seat 503.

[0035] After adjusting the position of the grinding knife 508, the locking nut 5092 is tightened to firmly fix the mounting bolt 5091, so that the mounting bolt 5091 is prevented from loosening during the rotation of the rotating cylinder 504, thereby ensuring the stability of the position of the grinding knife 508 and ensuring the stability and reliability of the polishing effect of the die joint.

[0036] Another embodiment, as shown in Figure 2 , Figure 9 , the water tank 6 is mounted at the bottom of the equipment support 1, the mounting plate 501 has an opening 5011, the water tank 6 is provided with a water pump, the outlet end of the water pump is connected with a water outlet pipe 601, the water outlet pipe 601 passes through the opening 5011, and the outlet end faces the grinding knife 508.

[0037] The water tank 6 is used for storing cooling liquid or water for cooling. When the grinding knife 508 polishes the die joint, the water pump is started to deliver the cooling liquid in the water tank 6 to the grinding knife 508 through the water outlet pipe 601 to cool the grinding knife 508, so as to prevent the grinding knife 508 from being severely worn or damaged due to high temperature. At the same time, the cooling liquid can also carry away the dust generated during polishing, play a dust-reducing role, improve the working environment, and also be beneficial to ensuring the cleanliness of the polished die joint, facilitating subsequent cutting operation.

[0038] At this time, the prepared wallboard is placed on the wallboard support frame 7 of the wallboard fixing device by a gantry crane or other lifting device, the telescopic cylinder 701 is extended, and the clamping plate 702 is driven to clamp and fix the wallboard. Then, the camera 102 takes a photo of the concrete wallboard to record the position of the joint and the steel bar and determine the angle of the steel bar. Then, the auxiliary manipulator 4 moves to straighten the steel bar. Then, the sleeve 505 is still sleeved above the steel bar at the joint, and the joint is polished and cut. At the same time, the water pump in the water tank 6 is started, the water outlet pipe 601 discharges water, the grinding tool 508 is cooled and dusted, and an opening with a diameter larger than the rotating cylinder 504 is formed at the steel bar. Then, the sleeve 505 moves out of the steel bar upwards, and the cutting manipulator 2 drives the cutting saw 3 to move to the joint to cut the joint. In this process, the water outlet pipe 601 in the auxiliary assembly continuously sprays water towards the cutting saw 3 to cool and dust it.

[0039] At this time, there is another embodiment, which is different in that the sleeve 505 is still retained on the steel bar. At this time, a second water outlet pipe, not shown in the figure, is connected to the water pump, and the liquid outlet end of the second water outlet pipe is located on the cutting saw 3. When the cutting saw 3 cuts the joint, the second water outlet pipe discharges water to cool and dust the cutting saw 3, and the auxiliary assembly is sleeved on the steel bar to protect the steel bar from being cut by the cutting saw 3.

[0041] The wallboard support frame 7 provides a platform for placing the wallboard. The telescopic cylinder 701 serves as a power element. When the wallboard is placed on the wallboard support frame 7, the telescopic cylinder 701 is extended to drive the clamping plate 702 to move towards the wallboard, thereby clamping and fixing the wallboard on the wallboard support frame 7. This provides stable workpiece support for subsequent detection and cutting operations, ensures that the wallboard does not shift during the entire process, and ensures the accuracy of the operation.
