Description

[0002] When manufacturing single-layer steel mesh, the intersections of the reinforcing bars need to be welded and fixed. Currently, most steel meshes use welding machines to weld the intersections, such as Chinese patent CN 112743197B.

[0021] Please refer to the following: Figures 1 to 9 The rebar tying equipment provided in the embodiments of the present invention will now be described.

[0022] like Figures 1 to 6 As shown, the rebar tying equipment of this embodiment includes: a moving component 100, an angle adjuster 200, and a tying box 300; The angle adjuster 200 includes a connecting seat 210, a rotating column 220, and a first driving device 230. The rotating column 220 is rotatably connected to the connecting seat 210, and the first driving device 230 is disposed on the connecting seat 210. The rotating device is used to drive the rotating column 220 to rotate. The moving component 100 is connected to the connecting seat 210. The rotating column 220 is connected to the binding box 300. The extending direction of the rotating column 220 is vertical, so that the binding box 300 can rotate under the drive of the first driving device 230 to adjust the relative angle between the binding box 300 and the intersection point 600. The moving component 100 can drive the angle adjuster and the binding box 300 to align with the intersection point 600 of the steel mesh. The binding box 300 includes a box body 310, a solder feeding assembly 320, and an opening and closing mold 330. The opening and closing mold 330 includes a second driving device 331 and four mold claws 332. The four mold claws 332 are evenly distributed on the lower side of the box body 310 around the rotation axis of the rotating column 220. All four mold claws 332 are rotatably connected to the box body 310, and the rotation axis of the four mold claws 332 is perpendicular to the rotation axis of the rotating column 220. The rotation axis of the rotating column 220 is as follows: Figure 2 As shown in L; the second driving device 331 is disposed on the housing 310, and the second driving device 331 is used to drive the four mold claws 332 to switch back and forth between the open and closed states; see reference Figures 2 to 6 The four die claws 332 are shaped like grippers. The second drive device 331 drives the four die claws 332 to rotate outward or inward simultaneously, so as to control the four die claws 332 to switch back and forth between the open and closed states; see reference. Figure 4 The four mold claws 332 are in the open state.

[0023] Reference Figure 2 , Figure 5 and Figure 6 The four die claws 332 are in a closed state. When the four die claws 332 are in a closed state, a welding cavity 340 for accommodating the intersection point 600 of the intersecting reinforcing bars is formed between the lower side of the housing 310 and the four die claws 332, and the lower ends of the four die claws 332 are combined to form a support platform 350 for carrying molten solder. The solder feeding assembly 320 is provided with a solder inlet 321 located on the lower side of the housing 310, and the solder inlet 321 is located above the support platform 350. The welding cavity 340 can accommodate the intersection point 600 of the intersecting reinforcing bars, see reference. Figure 4 and Figure 5 When the four jaws 332 switch from the open state to the closed state, they act like grippers, holding the binding box 300 tightly and positioning the intersection point 600 of the cross reinforcing bars within the welding cavity 340. This aligns the intersection point 600 with the solder inlet 321, thus fixing the intersection point 600 to the binding box 300. (Refer to...) Figure 7 In the diagram, the black area represents molten solder. When the four die claws 332 are in the closed state and the intersection point 600 of the cross reinforcing bars is within the welding cavity 340, the solder feeding assembly 320 delivers the molten solder to the solder inlet 321. The molten solder will fall into the intersection point 600 within the welding cavity 340. Since there is a support platform 350 composed of die claws 332 below the intersection point 600, the molten solder will not fall directly to the ground. The molten solder will cover the intersection point 600 of the cross reinforcing bars. After the solder cools down, the purpose of welding the intersection point 600 of the cross reinforcing bars is achieved. At this time, the second drive device 331 can drive the die claws 332 to switch from the closed state to the open state to release the binding box 300 from the intersection point 600 of the cross reinforcing bars so as to perform welding of the intersection point 600 of the reinforcing bars.

[0024] After welding is completed at the intersection point 600 of a cross rebar, the second drive device 331 will drive the four die claws 332 to switch from the closed state to the open state. Then, the moving component 100 drives the angle adjuster 200 and the binding box 300 to move upward, so that the height of the die claws 332 is higher than the entire rebar mesh. Then, it drives the angle adjuster 200 and the binding box 300 to move above another intersection point 600. Subsequently, the first drive device 230 of the angle adjuster 200 is activated to adjust the angle between the binding box 300 and the intersection point 600, so that the four die claws 332 can be aligned with the four included angles of the intersection point 600. Figure 6As shown, at this time, the first drive device 230 is closed to ensure that the angle of the binding box 300 does not move arbitrarily; finally, the moving component 100 drives the binding box 300 and the angle adjuster 200 to descend, so that the four claws 332 of the opening and closing mold 330 descend to the position shown. Figure 4 The position is such that the intersection point 600 is located between the four die claws 332, and the second drive device 331 drives the four die claws 332 to retract inward, so that the four die claws 332 switch from the open state to the closed state, as shown. Figure 5 As shown, the binding box 300 and the intersection point 600 can then be fixed together for welding of the intersection point 600. (Refer to...) Figure 7 In the diagram, the black area represents molten solder. When the four die claws 332 are closed and the intersection point 600 of the intersecting reinforcing bars is within the welding cavity 340, the solder feeding assembly 320 delivers the molten solder to the solder inlet 321. The molten solder falls into the intersection point 600 within the welding cavity 340. Because there is a support platform 350 composed of die claws 332 below the intersection point 600, the molten solder does not fall directly to the ground. Instead, it covers the intersection point 600 of the intersecting reinforcing bars. After the solder cools, the purpose of welding the intersection point 600 of the intersecting reinforcing bars is achieved. By repeating the above process, the reinforcing bar binding equipment can weld multiple intersection points 600 of the reinforcing bar mesh.

[0025] In this embodiment, the rebar tying equipment uses a moving component 100 and an angle adjuster 200 to adjust the position of the tying box 300. This allows the opening and closing mold 330 of the tying box 300 to be moved to the intersection point 600 of the rebar mesh to be welded. The four jaws 332 of the opening and closing mold 330 are aligned with the four included angles of the intersection point 600. When the four jaws 332 switch from an open state to a closed state, they act like clamps, gripping the tying box 300 tightly, placing the intersection point 600 within the welding cavity 340 and aligning it with the solder inlet 321. This achieves rapid fixation of the intersection point 600 to the tying box 300. The purpose of positioning is to allow molten solder to be injected into the welding cavity 340 from the solder inlet 321, so that the intersection 600 can be welded, achieving the purpose of rapid positioning and rapid welding. Compared with the existing method that requires multiple adjustments to position the welding gun so that it is aligned with the welding point 600, the rebar binding equipment in this embodiment directly allows the four die claws 332 to extend into the four corners of the intersection 600 to complete the positioning. Moreover, there is no need to move the position of the binding box 300 during the welding process, so that the welding action of the intersection 600 can be completed after one positioning, which reduces positioning accuracy, shortens welding time, reduces welding difficulty, and improves welding efficiency.

[0026] In some embodiments, reference is made to Figures 2 to 5The die claw 332 includes an extension section 333 and a bent section 334. The bent section 334 is located at the lower end of the extension section 333, and the end of the extension section 333 away from the bent section 334 is rotatably connected to the lower end of the housing 310. The bent section 334 bends relative to the extension section 333 toward the solder inlet 321, and the bent section 334 is in the shape of a right-angled triangle. The long side of the right-angled triangle is connected to the extension section 333. When the four die claws 332 are in the closed state, the four bent sections 334 combine to form the support platform 350. The bent section 334 bends toward the solder inlet 321 so that the combined support platform 350 can be set horizontally, so that the support platform 350 can better contact the reinforcing bars under the intersection point 600, so that the molten solder can better cover the intersection point 600, thereby achieving the purpose of welding. The extension section 333 is used to allow a predetermined distance between the bending section 334 and the lower side of the housing 310, so as to leave enough space for the opening and closing mold 330 to clamp the intersection point 600.

[0027] In some embodiments, reference is made to Figures 2 to 5 The extension section 333 has heat-resistant soft silicone baffles 335 on both sides of its edge; the lower end of the heat-resistant soft silicone baffles 335 extends to the connection between the extension section 333 and the bent section 334. By providing the heat-resistant soft silicone baffles 335, molten solder can be prevented from leaking from the edge of the die claw 332, reducing the likelihood of molten solder dripping onto the ground. The heat-resistant soft silicone baffles 335 have a temperature resistance of at least 200 degrees Celsius, preventing melting during welding. Furthermore, the soft heat-resistant soft silicone baffles 335 can better conform to the reinforcing steel, sealing the gap between the die claw 332 and the reinforcing steel. The die claw 332 is made of stainless steel. Specifically, the heat-resistant soft silicone baffles 335 can be made using Best's BST-S-120 high-temperature resistant silicone pad.

[0028] In some embodiments, reference is made to Figures 2 to 5 The second driving device 331 includes four second driving motors, all of which are mounted on the housing 310. Each second driving motor drives one of the die claws 332 to rotate. That is, each die claw 332 corresponds to one second driving motor, which drives the die claw 332 to rotate. It is understood that the second driving motor can drive the die claw 332 to rotate via a gear set or a linkage mechanism, and this can be adjusted according to the specific mechanism.

[0029] In some embodiments, reference is made to Figure 2 , Figure 6 , Figure 9The rebar tying equipment also includes a controller 400. At least two distance sensors 311 for detecting rebar are provided on the lower side of the housing 310. Multiple distance sensors 311 are evenly distributed around the rotation axis of the rotating column 220. The controller 400 is signal-connected to the distance sensors 311, the solder feeding assembly 320, the moving assembly 100, the angle adjuster 200, and the opening / closing mold 330. The distance sensor 311 is a distance-sensing lens used to detect the distance between the lower side of the housing 310 and the upper layer of rebar at the intersection point 600. The controller 400 stores a preset distance. When the moving assembly 100 moves the tying box 300 from top to bottom towards the intersection point 600 of the rebar mesh, if the distance sensor 311 detects that the distance between the upper layer of rebar and the lower side of the housing 310 is equal to the preset distance, the controller 400 controls the moving assembly 100 to stop, preventing the tying box 300 from continuing to move downwards. The controller 400 stores a preset amount of molten solder to be output during soldering. When soldering is required, the controller 400 activates the solder feeding assembly 320, causing the preset amount of molten solder to be output from the solder inlet 321. After outputting, the solder feeding assembly 320 stops to prevent excessive molten solder from being discharged from the solder inlet 321. The controller 400 controls the angle adjuster 200 by controlling the opening and closing of the first drive device 230 to adjust the angle between the binding box 300 and the intersection point 600. The controller 400 controls the opening and closing of the second drive device 331 to control the simultaneous rotation of the four die claws 332, allowing the die claws 332 to switch between open and closed states.

[0030] In some embodiments, reference is made to Figure 2 , Figure 6 , Figure 9To better adjust the angle between the binding box 300 and the intersection point 600, the rebar binding equipment also includes: multiple positioning cameras 500; the multiple positioning cameras 500 are arranged on the lower outer side of the box 310, and the lenses of the positioning cameras 500 face directly below the opening and closing mold 330. The positioning cameras 500 are signal connected to the controller 400. A wireless transceiver is provided on the outer side of the box 310. The wireless transceiver is wirelessly connected to the controller 400, and is electrically connected to the solder feeding assembly 320, the angle adjuster 200, the opening and closing mold 330, the distance sensor 311, and the positioning cameras 500. It can be understood that the signal connection can be an electrical signal connection, a WIFI signal connection, etc. The controller 400 is a PLC or MCU control chip. In this embodiment, the number of positioning cameras 500 is four, the same as the number of mold claws 332, to facilitate detection of whether the mold claws 332 are located at the included angle of the intersection point 600. When the binding box 300 is above the intersection 600, the positioning camera 500 takes a picture of the position of the intersection 600 and sends the captured image information to the controller 400. The controller 400 analyzes the captured image information to determine whether the binding box 300 is directly above the intersection 600 and whether the four claws 332 can be aligned with the four corners of the intersection 600.

[0031] In some embodiments, reference is made to Figure 2 , Figure 4 , Figure 5The solder feeding assembly 320 includes a solder wire pusher 322, a heating tube 323, and a heat insulation block 324. The heat insulation block 324 has a vertically arranged grouting channel 325 that communicates with the solder feeding port. The heating tube 323 is located above the grouting channel 325, and the lower end outlet of the heating tube 323 communicates with the grouting channel 325. The solder wire pusher 322 includes two wire feeding rollers 326 and a third driving device for driving the two wire feeding rollers 326 to rotate. There is a wire feeding gap 327 between the two wire feeding rollers 326 for allowing the solder wire to pass through. The wire feeding gap 327 is located above the upper end inlet of the heating tube 323. The heating tube 323 consists of a heat-resistant ceramic tube and a heating copper coil sleeved on the outside. The heating copper coil is connected to a battery located inside the housing 310. When the heating copper coil is energized, it can generate heat to heat the heat-resistant ceramic tube. The inlet of the heating tube 323 is used to allow the solder wire to enter. The third driving device is a drive motor to drive the wire feeding roller 326 to rotate, thereby pushing the solder wire entering the wire feeding gap 327 downward so that the solder wire enters the heating tube 323. After entering the heating tube 323, the solder wire will be heated into molten solder. The molten solder is output from the outlet of the heating tube 323 to the grouting channel 325 and sent out from the solder delivery port 321 to ensure that the molten solder can enter the welding chamber 340 for welding. Understandably, the insulation block 324 reduces heat transfer, allowing the molten solder to pass normally through the injection channel 325. The injection channel 325 can be made of stainless steel tubing to prevent the molten solder from sticking to the insulation block 324 and to maintain a higher temperature in the stainless steel tubing, preventing the molten solder from blocking the injection channel 325. The insulation tube is filled with asbestos. The insulation block 324 reduces the heat transferred outward from the injection channel 325 by the molten solder, ensuring that the injection channel 325 is maintained at a higher temperature and preventing blockage. Understandably, the controller 400 controls the amount of molten solder output by controlling the opening and closing of the third drive device, and controls whether the heating tube 323 heats by controlling the opening and closing of the control switch between the heating tube 323 and the battery.

[0032] In some embodiments, reference is made to Figure 2 , Figure 4 , Figure 5 The housing 310 also includes a rotating frame 312, which is rotatably connected to the housing 310. The rotating frame 312 is used to support the solder coil. The rotating frame 312 supports the solder coil used for soldering to ensure that there is enough solder wire input into the heating tube 323 and that the molten solder can be output normally from the solder inlet 321 for soldering at the intersection 600.

[0033] In some embodiments, reference is made to Figure 1The moving component 100 includes a gantry frame 110, a multi-axis robotic arm 120, and a first slider 130. The gantry frame 110 has a crossbeam 111 and two vertical beams 112. The crossbeam 111 is provided with a first slide rail 113. The multi-axis robotic arm 120 is connected to the connecting seat 210, and the multi-axis robotic arm 120 is slidably connected to the first slide rail 113 via the first slider 130. The first slider 130 is provided with a drive wheel 131 and a fourth drive device 132. The drive wheel 131 contacts the crossbeam 111, and the fourth drive device 132 is connected to the drive wheel 131, and the fourth drive device 132 drives the drive wheel 131 to rotate. The gantry 110 is used to suspend the multi-axis robotic arm 120 and the first slider 130. The fourth drive device 132 drives the drive wheel 131 to rotate, allowing the first slider 130 to move along the crossbeam 111, thereby moving the multi-axis robotic arm 120, the angle adjustment device, and the binding box 300. This allows the binding box 300 to weld at multiple different intersection points 600. The multi-axis robotic arm 120 is mainly used to lift and lower the binding box 300. Specifically, the multi-axis robotic arm 120 is a three-axis robotic arm. In addition, the multi-axis robotic arm 120 can also be a four-axis, five-axis, or six-axis robotic arm. It should be noted that the connecting seat 210 is directly hinged to the multi-axis robotic arm 120 through a hinge shaft to ensure that the binding box 300 is vertical under its own weight. Alternatively, the multi-axis robotic arm 120 can also be used to keep the binding box 300 vertical. Horizontal guide rails 140 can be installed on both sides of the vertical beam 112 of the gantry frame 110. The vertical beam 112 is slidably connected to the horizontal guide rails 140 so that the gantry frame 110 can move along the horizontal guide rails 140. The length direction of the horizontal guide rails 140 is perpendicular to the cross beam 111 so as to drive the binding box 300 to move in the horizontal plane so as to weld multiple different intersection points 600 of the steel mesh.

[0034] In some embodiments, reference is made to Figure 2 , Figure 8 , Figure 9 The first driving device 230 includes a first driving motor 231, a belt transmission mechanism 232, a first angle adjusting wheel 233, and a second angle adjusting wheel 234. The second angle adjusting wheel 234 is disposed on the rotating column 220 and meshes with the first angle adjusting wheel 233. The first angle adjusting wheel 233 is rotatably connected to the connecting seat 210. The first driving motor 231 drives the first angle adjusting wheel 233 to rotate through the belt transmission mechanism 232, which ensures that the rotating column 220 rotates relative to the connecting seat 210 to adjust the relative angle between the binding box 300 and the intersection 600, so that the four die claws 332 are aligned with the four included angles of the intersection 600, ensuring that the four die claws 332 can clamp and cross-position like grippers for welding.

[0035] The fourth drive device 132 is a drive motor. All of the aforementioned drive motors can rotate forward and backward to move in different directions. The controller 400 controls the forward and reverse rotation of the fourth drive device 132 to allow the first slider 130 to move in different directions along the first slide rail 113.

[0036] In summary, the rebar tying equipment of this embodiment uses the moving component 100 and the angle adjuster 200 to adjust the position of the tying box 300. This allows the opening and closing mold 330 of the tying box 300 to be moved to the intersection point 600 of the rebar mesh to be welded, and the four jaws 332 of the opening and closing mold 330 to be aligned with the four included angles of the intersection point 600. When the four jaws 332 switch from the open state to the closed state, they act like clamps to grip the tying box 300, placing the intersection point 600 within the welding cavity 340 and aligning the intersection point 600 with the solder inlet 321, thereby quickly tying the intersection point 600 to the tying box 300. The purpose of fixed positioning is to allow molten solder to be injected into the welding cavity 340 from the solder inlet 321, so that the intersection 600 can be welded, achieving the purpose of rapid positioning and rapid welding. Compared with the existing method that requires multiple adjustments to the position so that the welding gun is aligned with the welding point 600, the rebar binding equipment in this embodiment directly allows the four die claws 332 to extend into the four corners of the intersection 600 to complete the positioning. Moreover, there is no need to move the position of the binding box 300 during the welding process, so that the welding action of the intersection 600 can be completed after one positioning, which reduces the positioning accuracy, shortens the welding time, reduces the welding difficulty, and improves the welding efficiency.

[0037] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and substitutions without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
