Description

Technical Field

[0001] This invention belongs to the field of welding machine technology, specifically relating to a CNC fully automatic steel wire mesh welding device. Background Technology

[0002] Currently, automated steel rebar welding mesh production lines are widely used. Their main structure includes a frame, straightening mechanism, transverse bar feeding mechanism, longitudinal bar feeding mechanism, welding host, mesh cutting machine, and collection table. The welding electrode heads on existing welding machines are usually fixed. When producing mesh sheets of different specifications, the machine needs to be stopped and workers need to adjust the position of the electrode heads, or even replace the entire welding beam. This process is time-consuming and labor-intensive, and is not suitable for small-batch, multi-specification orders. In addition, the surface of the reinforcing bars may have impurities such as oxide scale, rust, and oil, which will affect the stability of resistance welding and easily lead to problems such as incomplete welds, overheating, and weak welds. Furthermore, after long-term use, the electrode heads may wear down, resulting in insufficient pressure or reduced contact area, which will also affect the welding quality. Existing welding equipment lacks a monitoring and compensation mechanism for electrode head wear. Finally, the transverse ribs are usually not dropped or gripped by claws. For long mesh sheets, the transverse ribs are prone to bouncing during placement, resulting in inaccurate intersections with the longitudinal ribs, causing weld point deviations and ultimately affecting the welding accuracy of the mesh sheet. This problem is particularly prominent during high-speed production. Therefore, there is an urgent need for a fully automatic welding device that is easy to adjust, has stable welding quality, and high material placement accuracy. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the background art and to provide a CNC fully automatic steel wire mesh welding device. This mesh welding device can quickly switch the mesh size, ensure stable weld quality through real-time feedback of the welding status, and use vision technology to correct the deviation of the material. It has the characteristics of convenient adjustment, precise welding, and reliability.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A CNC fully automatic steel wire mesh welding device includes a longitudinal bar feeding system, a transverse bar placing mechanism, an intelligent welding system, and a control system;

[0006] The longitudinal rib feeding system is responsible for the automatic supply and initial positioning of the longitudinal ribs. The longitudinal rib feeding system includes a frame, at least one set of wire feeding frames installed on the frame, a multi-roll straightener connected to the outlet of the wire feeding frame, a feeding mechanism driven by a first servo motor, and a longitudinal rib vision sensor module. The longitudinal ribs on the coil are led out by the wire feeding frame, straightened by the multi-roll straightener, and then fed to the welding station of the intelligent welding system by the feeding mechanism driven by the first servo motor according to a set length. The feeding mechanism sends the longitudinal ribs straightened by the multi-roll straightener to the intelligent welding system according to the instructions of the control system. The longitudinal rib vision sensor module identifies the straightness deviation of the longitudinal rib arrangement.

[0007] The intelligent welding system includes a welding support frame, an upper welding electrode assembly, a lower welding electrode assembly, and a pressurizing mechanism. The welding support frame is wrapped around the frame and can move along the length of the frame. The position of the welding support frame on the frame can be adjusted by a horizontal moving module. The upper welding electrode assembly includes multiple independently controlled welding head units arranged side by side. The upper welding electrode assembly is suspended on the welding support frame above the frame. The lower welding electrode assembly is vertically mounted on the welding support frame below the frame. The lower welding electrode assembly is provided with a copper seat corresponding to each welding head unit. The pressurizing mechanism is connected to each welding head unit of the upper welding electrode assembly to ensure uniform pressure at each weld point.

[0008] The transverse rib laying mechanism is installed on the welding support frame. The transverse rib laying mechanism includes a storage bin, a rib laying guide rail, a robot arm, and a transverse rib vision sensor module. Several robot arms are evenly arranged on the rib laying guide rail. The rib laying guide rail is driven by a second servo motor, so that the robot arms circulate along the rib laying guide rail to circulate and take out transverse ribs from the storage bin to the intelligent welding system. The transverse rib vision sensor module detects the alignment of the intersection of the longitudinal ribs and transverse ribs at the intelligent welding system.

[0009] The control system is electrically connected to the longitudinal rib feeding system, the transverse rib feeding mechanism, and the intelligent welding system. The control system adjusts the positions of the longitudinal and transverse ribs according to the information fed back by the longitudinal rib vision sensor module and the transverse rib vision sensor module, respectively. It also adjusts the welding pressure at the intersection of the longitudinal and transverse ribs through the pressurizing mechanism. According to the welding process requirements, it applies independent and precise welding pressure to each welding electrode and performs closed-loop welding during the welding process.

[0010] The welding support frame is machined with two grooves corresponding to the positions of the upper and lower welding electrode assemblies. Each groove contains several adjusting blocks. The welding head unit of the upper welding electrode assembly corresponds one-to-one with the adjusting block, and each copper seat of the lower welding electrode assembly corresponds one-to-one with the adjusting block. The groove contains a rack, and each adjusting block is equipped with a first stepper motor. Each first stepper motor is equipped with a gear that meshes with the rack. By controlling the first stepper motor, the lateral position of each welding unit on the frame can be adjusted independently and precisely, thereby quickly adapting to the generation of mesh sheets of different sizes and greatly enhancing the flexibility of the equipment.

[0011] The feeding mechanism includes a linear motion module, a sliding frame, a second stepper motor, and finger-clamping cylinders. The sliding frame is mounted on the linear motion module. A first servo motor drives the sliding frame to reciprocate between the multi-roller straightener and the welding station via the linear motion module. A guide rail parallel to the transverse rib feeding mechanism is mounted on the top of the sliding frame. A row of teeth is machined on the guide rail. Several finger-clamping cylinders are slidably mounted in the guide rail via sliders. A second stepper motor is mounted on each slider. A toothed wheel that meshes with the teeth is mounted on the output shaft of the second stepper motor. The position of the finger-clamping cylinder is aligned with the corresponding welding head unit. Each finger-clamping cylinder can be independently moved and positioned on the guide rail by the second stepper motor and the toothed wheel, ensuring that each longitudinal rib can be accurately clamped and fed to the bottom of the corresponding welding head unit. In conjunction with the multi-roller straightener that can slide left and right, independent channel-type conveying and positioning of the longitudinal ribs is realized.

[0012] The multi-roller straightener can be slidably mounted on the end of the pay-off frame, with each straightener aligned with its corresponding finger-clamping cylinder.

[0013] The longitudinal rib vision sensor module is installed on the side wall of the welding support frame above the longitudinal rib conveying path, and the transverse rib vision sensor module is installed on the upper part of one side of the welding support frame.

[0014] The welding support frame is equipped with a servo push rod for adjusting the position of the transverse ribs.

[0015] The pressurizing mechanism includes an AC servo motor, a ball screw, and a pressure sensor. The AC servo motor is connected to the screw shaft of the ball screw, and the nut assembly of the ball screw is fixedly connected to the welding head unit through a connecting sleeve. The pressure sensor is installed between the connecting sleeve and the nut assembly of the ball screw. Through the cooperation of the AC servo motor, the ball screw, and the pressure sensor, high-precision and fast-response pressure control can be provided.

[0016] The copper base is a hollow structure and is cooled by water circulation.

[0017] A cutting device is provided on the frame at the rear of the welding support frame.

[0018] The beneficial effects of the CNC fully automatic steel wire mesh welding device provided by this invention are:

[0019] (1) Through the longitudinal reinforcement feeding system, the transverse reinforcement feeding mechanism, the intelligent welding system and the control system, the grid size can be switched quickly, the welding status can be fed back in real time to ensure the quality of the weld point is stable, and the deviation of the reinforcement feeding can be corrected by visual technology. It has the characteristics of convenient adjustment, precise welding and reliability, while ensuring production efficiency.

[0020] (2) By using the longitudinal rib vision sensor module and the transverse rib vision sensor module, together with the adjustment block on the welding support frame and the slider on the feeding mechanism, the intersection position of the longitudinal rib and the transverse rib can be monitored online and dynamically corrected, ensuring the high precision of the grid size.

[0021] (3) The multi-welding head unit design with independent horizontal adjustment and the independent servo pressurization mechanism enable the equipment to quickly adapt to the production of different specifications of mesh and to accurately control the pressure of each welding point, so that the welding quality is stable and reliable.

[0022] (4) The overall structure is compact, highly integrated, and operates smoothly in an automated manner. Attached Figure Description

[0032] like Figures 1-7 As shown, the CNC fully automatic steel wire mesh welding device provided in this embodiment is mainly a production line distributed along the longitudinal bar conveying direction, including a longitudinal bar feeding system 1, a transverse bar feeding mechanism 2, an intelligent welding system 3, and a control system 4.

[0033] like Figures 1-3As shown, the longitudinal rib feeding system 1 is responsible for the automatic supply and initial positioning of the longitudinal ribs. The longitudinal rib feeding system 1 includes a frame 11, at least one set of wire feeding frames 12 mounted on the frame 11, a multi-roll straightener 13 connected to the outlet of the wire feeding frame 12, a feeding mechanism 15 driven by a first servo motor 14, and a longitudinal rib vision sensor module 16. The wire feeding frame 12 is located at the beginning section of the frame 11. The longitudinal ribs on the coil are led out through the wire feeding frame 12, straightened by the multi-roll straightener 13, and then fed to the welding section of the intelligent welding system 3 by the feeding mechanism 15 driven by the first servo motor 14 according to a set length. At the receiving station, multiple support beams are installed on the frame 11 to support the longitudinal ribs. Each coil of longitudinal ribs corresponds to a multi-roller straightening machine. The multi-roller straightening machine 13 can be slidably installed at the end of the frame 11 for lateral position adjustment. After straightening, the longitudinal ribs enter the feeding mechanism 15. The feeding mechanism 15, according to the instructions of the control system 4, sends the longitudinal ribs straightened by the multi-roller straightening machine 13 to the intelligent welding system 3. The feeding mechanism 15 includes a linear motion module 151, a sliding frame 152, a second stepper motor 155, and a finger-gripping cylinder 157. The sliding frame 152 is installed on the linear motion module 151. The first servo motor 14 drives the sliding frame 152 to reciprocate between the multi-roller straightener 13 and the welding station via the linear motion module 151. A guide rail 153 parallel to the transverse rib feeding mechanism 2 is mounted on the top of the sliding frame 152. A row of teeth 154 is machined on the guide rail 153. Several finger-clamping cylinders 157 are slidably mounted within the guide rail 153 via sliders 158. A second stepper motor 155 is mounted on each slider 158. A toothed gear 156 meshing with the teeth 154 is mounted on the output shaft of the second stepper motor 155. The finger-clamping cylinders 157 are driven by the second stepper motor... The motor 155 drives the toothed wheel 156 to mesh with the teeth 154 on the guide rail 153 to achieve independent movement. Each gripper cylinder 157 is responsible for gripping a longitudinal rib and accurately pulling it from the outlet of the multi-roller straightener 13 to the welding station. It can be independently moved and positioned on the guide rail 153 by the second stepper motor 155 and the toothed wheel 156 to ensure that each longitudinal rib can be accurately gripped and sent to the bottom of the corresponding welding head unit. In conjunction with the multi-roller straightener 13 that can slide left and right, the independent channel-type conveying and positioning of the longitudinal rib is realized. The longitudinal rib vision sensor module 16 identifies the straightness deviation of the longitudinal rib arrangement.

[0034] like Figure 1 , Figures 4-7As shown, the intelligent welding system 3 includes a welding support frame 31, an upper welding electrode assembly 32, a lower welding electrode assembly 33, and a pressurizing mechanism 34. The welding support frame 31 is wrapped around the frame 11 and can move along the length of the frame 11. The position of the welding support frame 31 on the frame 11 can be adjusted by a horizontal moving module. The longitudinal rib vision sensor module 16 is installed on the side wall of the welding support frame 31 above the longitudinal rib conveying path. The welding support frame 31 has two grooves 311 machined on it, corresponding to the positions of the upper welding electrode assembly 32 and the lower welding electrode assembly 33. Each groove 311 is equipped with... There are several adjusting blocks 312. Each welding head unit of the upper welding electrode assembly 32 corresponds to one adjusting block 312, and each copper seat of the lower welding electrode assembly 33 corresponds to one adjusting block 312. A rack 316 is provided within the slide groove 311. Each adjusting block 312 is equipped with a first stepper motor 314, and each first stepper motor 314 is equipped with a gear 315 that meshes with the rack 316. By controlling the first stepper motor 314, the lateral position of each welding unit on the frame 11 can be adjusted independently and precisely, thereby quickly adapting to the generation of meshes with different longitudinal rib spacings. The upper welding electrode assembly 312... 2 includes multiple independently controlled welding head units arranged side-by-side. The upper welding electrode assembly 32 is suspended on a welding support frame 31 above the frame 11. The lower welding electrode assembly 33 is vertically mounted on the welding support frame 31 below the frame 11. The lower welding electrode assembly 33 is equipped with a copper seat corresponding to each welding head unit. The pressurizing mechanism 34 is connected to each welding head unit of the upper welding electrode assembly 32 to ensure uniform pressure at each weld point. The pressurizing mechanism 34 includes an AC servo motor 341, a ball screw 342, and a pressure sensor 343. 41 is connected to the screw shaft of the ball screw 342. The nut assembly of the ball screw 342 is fixedly connected to the welding head unit through the connecting cylinder 344. The pressure sensor 343 is installed between the connecting cylinder 344 and the nut assembly of the ball screw 342. The AC servo motor 341 drives the ball screw 342 to rotate, which is converted into linear motion of the nut assembly. The connecting cylinder 344 pushes the welding head unit down. At this time, the pressure sensor 343 monitors the pressure change in real time and feeds it back to the control system 4 to form a pressure closed-loop control to improve the welding quality. The copper seat is a hollow structure and the electrodes are cooled by water.

[0035] The transverse rib fabric distribution mechanism 2 is mounted on the welding support frame 31, such as Figure 1As shown, the transverse reinforcement feeding mechanism 2 includes a storage bin 21, a reinforcement feeding guide rail 22153, robotic arms 24, and a transverse reinforcement vision sensor module 25. The storage bin 21 stores transverse reinforcement of a fixed length. Several robotic arms 24 are evenly distributed on the reinforcement feeding guide rail 22153. The reinforcement feeding guide rail 22153 is driven by a second servo motor 23, causing the robotic arms 24 to circulate along the reinforcement feeding guide rail 22153 to circulate and extract transverse reinforcement from the storage bin 21 to the intelligent welding system 3. The several robotic arms 24 on it sequentially... A transverse rib is picked up from the storage bin 21, moved above the welding station, and then lowered so that the transverse rib lands on the positioned longitudinal rib. The transverse rib vision sensor module 25 detects the alignment of the intersection points of the longitudinal and transverse ribs at three locations in the intelligent welding system. The transverse rib vision sensor module 25 is installed on the upper part of one side of the welding support frame 31. The welding support frame 31 is equipped with a servo push rod 313 for adjusting the position of the transverse rib. The servo push rod 313 adjusts the transverse rib through the transverse rib vision sensor module 25.

[0036] like Figure 1 As shown, a cutting device 5 is provided on the frame 11 on the rear side of the welding support frame 31, which is used to cut the longitudinal ribs after the mesh is welded.

[0037] The control system 4 is electrically connected to the longitudinal rib feeding system 1, the transverse rib feeding mechanism 2, and the intelligent welding system 3. The control system 4 adjusts the positions of the longitudinal ribs and transverse ribs respectively based on the information fed back by the longitudinal rib vision sensor module 16 and the transverse rib vision sensor module 25. It also adjusts the welding pressure at the intersection of the longitudinal ribs and transverse ribs through the pressurizing mechanism 34. According to the welding process requirements, it applies independent and precise welding pressure to each welding electrode and performs closed-loop welding during the welding process.

[0038] The method of using this invention is as follows:

[0039] According to the production task, adjust the positions of the finger-clamping cylinder 157 on the corresponding multi-roller straightener 13, the upper welding electrode assembly 32, and the lower welding electrode assembly 33 to the target positions. Then, the feeding mechanism 15 operates to send a row of longitudinal ribs to the welding station or drives the welding support frame 31 to move to the end, sending the ends of the longitudinal ribs into the welding station for initial welding. Check if it meets the requirements. If not, the feeding mechanism 15 performs intermittent feeding. During the intermittent feeding, the transverse rib feeding mechanism 2 operates to send the transverse ribs to the welding station. Next, the horizontal rib vision sensor module 25 detects and directs the servo push rod 313 to make fine adjustments for alignment. Subsequently, the welding frame 11 drives all welding head units to move above the intersection of the horizontal and vertical ribs, driving each welding head unit. During this process, the pressure mechanism 34 adjusts the position of each welding head to reach the preset pressure value before powering on for welding. After completion, the upper welding electrode assembly 32 is lifted, and the above steps are repeated. The intersection is detected by the vertical rib vision sensor module 16 and the horizontal rib vision sensor module 25, and the next welding is performed.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications and substitutions based on the technical solutions and inventive concepts provided by the present invention should be covered within the scope of protection of the present invention.
