Description

Technical Field

[0001] This invention relates to the field of building equipment technology, and in particular to a welding apparatus and welding method. Background Technology

[0002] like Figure 1 and Figure 2 As shown, the reinforcing cage for the ground wall consists of a top mesh 100, a truss 200, a bottom mesh 300, and sealing bars 400. Both the top mesh 100 and the bottom mesh 300 are composed of multiple intersecting horizontal and vertical reinforcing bars, which are welded together at the intersections to complete the fabrication. Figure 1 As shown, the mesh panel 100 includes multiple upper horizontal ribs 101 spaced apart along the X-axis and multiple upper vertical ribs 102 spaced apart along the Y-axis, with the upper horizontal ribs 101 connected to the upper side of the upper vertical ribs 102; the lower mesh panel 300 includes multiple lower horizontal ribs 301 spaced apart along the X-axis and multiple lower vertical ribs 302 spaced apart along the Y-axis, with the lower horizontal ribs 301 connected to the lower side of the lower vertical ribs 302; the truss 200 is disposed between the mesh panel 100 and the lower mesh panel 300, with both ends connected to the upper vertical ribs 102 and the lower vertical ribs 302 respectively; multiple sealing ribs 400 are provided, with upper sealing ribs 401 and lower sealing ribs 402 extending along the Y-axis, with the multiple upper sealing ribs 401 connected one-to-one to the horizontal side of the multiple upper horizontal ribs 101, and the multiple lower sealing ribs 402 connected one-to-one to the horizontal side of the multiple lower horizontal ribs 301.

[0003] When fabricating the reinforcing cage, workers first fabricate the lower mesh 300, then install the truss 200, followed by the upper mesh 100 above the truss 200, and finally weld the sealing bars 400. When welding the sealing bars 400, the lower sealing bar 402 is welded to the lower horizontal bar 301 of the lower mesh 300, and the upper sealing bar 401 is welded to the upper horizontal bar 101 of the mesh 100. This creates a weld seam between the upper sealing bar 401 and the upper horizontal bar 101.

[0004] Currently, the welds are still being completed manually. Due to the large number of 400mm sealing ribs, the long welding time, and the high labor intensity for workers, the work efficiency is low, it is unsafe, and the welding quality is unstable. Moreover, during the welding process, the deviation between the weld and the welding torch makes the welding operation difficult and the welding quality hard to guarantee. Summary of the Invention

[0005] The purpose of this invention is to provide a welding device that facilitates welding the weld seam between the upper horizontal rib and the upper sealing rib, making the operation safe and efficient, and improving the welding quality.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A welding device is used for welding the mesh and sealing bars of a reinforcing cage. The mesh includes multiple upper horizontal bars spaced apart along the X-axis and multiple upper vertical bars spaced apart along the Y-axis. The upper horizontal bars are connected to the upper sides of the upper vertical bars. Multiple sealing bars are provided, with the upper sealing bars of each sealing bar correspondingly connected to one side of the multiple upper horizontal bars. The welding device includes:

[0008] frame;

[0009] A traveling mechanism, mounted on the frame, is capable of driving the frame to move along the X-axis.

[0010] A lifting mechanism is mounted on the frame, and the lifting mechanism includes a lifting platform that is movable relative to the frame along the Z-axis.

[0011] A guiding mechanism, mounted on the lifting platform, includes a guide platform and guide wheels. The guide platform is movable relative to the lifting platform along the Y-axis, and the guide wheels are movably connected to the guide platform along the X-axis.

[0012] A welding mechanism is connected to the guide platform. When the guide platform moves along the Y-axis, the guide wheel can be rolled and connected to the upper horizontal rib, and drive the welding mechanism to move along the X-axis. The welding mechanism is configured to weld the weld seam between the upper horizontal rib and the upper sealing rib.

[0013] Optionally, the lifting mechanism further includes a lifting driver, the output end of which is connected to the lifting platform and drives the lifting platform to move along the Z-axis.

[0014] Optionally, the guiding mechanism includes a guiding driver, the output end of which is connected to the guiding table and drives the guiding table to move relative to the lifting platform along the Y-axis.

[0015] Optionally, the guiding mechanism further includes:

[0016] The positioning shaft is connected to the guide platform at both ends;

[0017] A connecting seat is slidably disposed on the positioning shaft along the X-axis direction and is rotatably provided with the guide wheel; the welding mechanism is disposed on the connecting seat.

[0018] The return springs are used to abut against the guide platform at both ends of the connecting seat along the X-axis.

[0019] Optionally, the welding mechanism further includes a welding driver and a welding torch, the output end of which is connected to the welding torch and drives the welding torch to extend.

[0020] Optionally, the welding device further includes a transverse rib detector, which is communicatively connected to the traveling mechanism. When the transverse rib detector detects the upper transverse rib, the traveling mechanism moves along the X-axis so that the guide wheel is positioned directly above the upper transverse rib.

[0021] Optionally, the transverse rib detector is disposed on the lifting platform and spaced apart from the guide wheel along the X-axis. When the transverse rib detector detects the upper transverse rib, the traveling mechanism moves by a fixed offset along the X-axis, the fixed offset being the distance between the transverse rib detector and the guide wheel along the X-axis.

[0022] Optionally, the welding device further includes a transverse rib end detector, which is connected to the guide platform and communicatively connected to the welding mechanism. When the transverse rib end detector detects the end of the upper transverse rib, the welding mechanism moves from the starting point along the Y-axis to weld the weld seam to be welded.

[0023] Optionally, when the transverse rib end detector detects the end of the upper transverse rib, the welding mechanism moves a preset distance along the Y-axis direction, the preset distance being the connection length between the upper sealing rib and the upper transverse rib.

[0024] Another objective of this invention is to provide a welding method that facilitates welding the weld seam between the upper horizontal rib and the upper sealing rib, resulting in safer and more efficient operation and better welding quality.

[0025] To achieve this objective, the present invention adopts the following technical solution:

[0026] A welding method, using the welding apparatus described above, includes:

[0027] Step 1: The traveling mechanism drives the frame to move along the X-axis. When the transverse rib detector detects the upper transverse rib, the traveling mechanism moves along the X-axis by a fixed offset to move the guide wheel directly above the upper transverse rib.

[0028] Step 2: The lifting driver drives the lifting platform to move along the Z-axis so that the guide wheel abuts against the upper horizontal rib;

[0029] Step 3: The guide table moves relative to the lifting table along the Y-axis to drive the guide wheel, welding mechanism and transverse rib end detector to move. When the transverse rib end detector detects the end of the upper transverse rib, the welding driver drives the welding torch to extend to the starting point.

[0030] Step 4: The guide table moves the welding torch a preset distance from the starting point along the Y-axis to weld the weld seam to be welded. During this process, the guide wheel is rolled on the upper horizontal rib, and the connecting seat moves the welding torch along the X-axis.

[0031] Beneficial effects:

[0032] The welding apparatus provided by this invention is used for welding the mesh and sealing bars of a reinforcing cage. The welding apparatus includes a frame, a traveling mechanism, a lifting mechanism, a guiding mechanism, and a welding mechanism. The traveling mechanism is mounted on the frame and can move the frame along the X-axis, facilitating placement on one side of the reinforcing cage for operation. The lifting mechanism is mounted on the frame and includes a lifting platform that can move relative to the frame along the Z-axis. A guiding mechanism is mounted on the lifting platform, allowing the guiding mechanism to move synchronously with the lifting platform along the Z-axis, facilitating reinforcing bar welding. The guiding mechanism includes a guide table and guide wheels. The guide table can move relative to the lifting platform along the Y-axis, thereby guiding the welding mechanism along the extension direction of the upper transverse reinforcing bars, improving welding quality. The guide wheels are movably connected to the guide table along the X-axis. The welding mechanism is connected to the guide table and can move with the guide table along the Y-axis, facilitating welding operations on the weld seam. When the guide table moves along the Y-axis, the guide wheel can roll and connect to the upper transverse rib, driving the welding mechanism to move along the X-axis. The welding mechanism is used to weld the weld between the upper transverse rib and the upper sealing rib. When the extension direction of the upper transverse rib deviates from the working direction of the welding mechanism, the guide wheel can move along the X-axis to slightly adjust the welding mechanism, ensuring the welding quality and operational safety of the weld. With the above configuration, the welding device of this application facilitates welding the weld between the upper transverse rib and the upper sealing rib, ensuring safe and efficient operation and better welding quality.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0050] like Figure 1 and Figure 2 As shown, the ground wall reinforcement cage consists of a top mesh 100, a truss 200, a bottom mesh 300, and sealing bars 400. Both the top mesh 100 and the bottom mesh 300 are composed of multiple intersecting horizontal and vertical bars, which are welded together at the intersections to complete the fabrication. The mesh panel 100 includes multiple upper horizontal ribs 101 spaced apart along the X-axis and multiple upper vertical ribs 102 spaced apart along the Y-axis. The upper horizontal ribs 101 are respectively cross-connected to the upper side of the multiple upper vertical ribs 102. The lower mesh panel 300 includes multiple lower horizontal ribs 301 spaced apart along the X-axis and multiple lower vertical ribs 302 spaced apart along the Y-axis. The lower horizontal ribs 301 are respectively cross-connected to the lower side of the multiple lower vertical ribs 302. Multiple trusses 200 are provided, and multiple trusses 200 are arranged between the mesh panel 100 and the lower mesh panel 300. The multiple upper vertical ribs 102 and multiple lower vertical ribs 302 correspond one-to-one. The reinforcing bars 302 are parallel to each other and spaced apart. The two ends of the truss 200 are respectively connected to the corresponding upper longitudinal bars 102 and lower longitudinal bars 302. There are multiple sealing bars 400. Multiple upper horizontal bars 101 and multiple lower horizontal bars 301 correspond one to one. The upper horizontal bars 101 and lower horizontal bars 301 are parallel to each other and spaced apart. Multiple sealing bars 400 are connected one to one to multiple upper horizontal bars 101 and lower horizontal bars 301. The sealing bars 400 have upper sealing bars 401 and lower sealing bars 402 extending along the Y-axis direction. Multiple upper sealing bars 401 are connected one to one to one horizontal side of multiple upper horizontal bars 101, and multiple lower sealing bars 402 are connected one to one horizontal side of multiple lower horizontal bars 301.

[0051] like Figure 2 As shown, during the welding process, a weld seam is formed between an upper horizontal rib 101 and an upper sealing rib 401. Multiple weld seams extend along the Y-axis and are spaced apart along the X-axis. Since manual welding of weld seams is not only time-consuming and labor-intensive, but also results in inconsistent welding quality, this embodiment proposes a welding device. This device can automatically identify the position of the weld seam using a corresponding detector and automatically perform welding. After the operation is completed, it can automatically locate and weld the next weld seam, thus automating the welding process and further improving weld quality.

[0052] like Figure 3 and Figure 4 As shown, this embodiment provides a welding device for welding the mesh sheet 100 and the sealing bar 400 of a reinforcing cage. The welding device includes a frame 1, a traveling mechanism 2, a lifting mechanism 3, a guiding mechanism 4, and a welding mechanism 5. The traveling mechanism 2 is mounted on the frame 1 and can drive the frame 1 to move along the X-axis. The lifting mechanism 3 is mounted on the frame 1 and includes a lifting platform 31, which can move relative to the frame 1 along the Z-axis. The guiding mechanism 4 is mounted on the lifting platform 31 and includes a guide table 41 and a guide wheel 42. The guide table 41 can move relative to the lifting platform 31 along the Y-axis. The guide wheel 42 is movably connected to the guide table 41 along the X-axis. The welding mechanism 5 is connected to the guide table 41. When the guide table 41 moves along the Y-axis, the guide wheel 42 can roll and connect to the upper horizontal bar 101, driving the welding mechanism 5 to move along the X-axis. The welding mechanism 5 is configured to weld the weld seam between the upper horizontal bar 101 and the upper sealing bar 401.

[0053] In this embodiment, the walking mechanism 2 is mounted on the frame 1 and can drive the frame 1 to move along the X-axis, facilitating the placement of the device on one side of the rebar cage for operation. The lifting mechanism 3 is mounted on the frame 1 and includes a lifting platform 31. The lifting platform 31 can move relative to the frame 1 along the Z-axis. A guide mechanism 4 is mounted on the lifting platform 31, allowing the guide mechanism 4 to move synchronously with the lifting platform 31 along the Z-axis, facilitating rebar welding. The guide mechanism 4 includes a guide table 41 and guide wheels 42. The guide table 41 can move relative to the lifting platform 31 along the Y-axis, thereby guiding the welding mechanism 5 along the extension direction of the upper transverse rib 101 and improving welding quality. The guide wheels 42 are movably connected to the guide table 41 along the X-axis. The welding mechanism 5 is connected to the guide table 41 and can move with the guide table 41 along the Y-axis, facilitating welding operations on the weld seam. When the guide table 41 moves along the Y-axis, the guide wheel 42 can roll and connect to the upper horizontal rib 101, driving the welding mechanism 5 to move along the X-axis. The welding mechanism 5 is used to weld the weld between the upper horizontal rib 101 and the upper sealing rib 401. When the extension direction of the upper horizontal rib 101 deviates from the working direction of the welding mechanism 5, the guide wheel 42 can move along the X-axis to slightly adjust the working direction of the welding mechanism 5, ensuring the welding quality and operational safety of the weld. With the above settings, the welding device of this embodiment facilitates welding the weld between the upper horizontal rib 101 and the upper sealing rib 401, ensuring safe and efficient operation and better welding quality.

[0054] It should be noted that in this embodiment, the X-axis and Y-axis are mutually perpendicular horizontal directions, while the Z-axis is a vertical direction, which facilitates the welding device in performing welding operations on the reinforcing cage. In other embodiments, the above directions can be adjusted according to the actual welding operation, and are not limited here.

[0055] Specifically, the walking mechanism 2 includes a base, a motor, and rollers. The frame 1 includes a column mounted on the base, the motor mounted in the base, and the rollers rotatably connected to the base. The output end of the motor is connected to the rollers and drives the rollers to rotate around their own axis, thereby realizing the movement of the frame 1 along the X-axis. Alternatively, the frame 1 can also move along the X-axis via hydraulic drive, and those skilled in the art are familiar with the specific working principle of hydraulic drive, which will not be elaborated here.

[0056] Specifically, such as Figure 3 and Figure 4 As shown, the lifting mechanism 3 also includes a lifting driver 32. The output end of the lifting driver 32 is connected to the lifting platform 31 and drives the lifting platform 31 to move along the Z-axis, thereby realizing the smooth movement of the lifting platform 31 along the Z-axis, which in turn drives the guide mechanism 4 and the welding mechanism 5 to move together along the Z-axis, so that the welding mechanism 5 can perform welding operations.

[0057] More specifically, in this embodiment, the lifting driver 32 is a cylinder, which is mounted on the frame 1. The piston rod of the cylinder is connected to the lifting platform 31 and drives the lifting platform 31 to move vertically, making the lifting motion more stable and controllable. In other embodiments, the lifting driver 32 can also be an electric cylinder or a hydraulic cylinder, as long as it can achieve the above functions, which will not be described in detail here.

[0058] Specifically, such as Figure 3 and Figure 4 As shown, the guiding mechanism 4 includes a guiding driver 43, the output end of which is connected to the guiding table 41 and drives the guiding table 41 to move relative to the lifting table 31 along the Y-axis. This enables the guiding table 41 to move smoothly along the extension direction of the upper horizontal rib 101, facilitating the welding mechanism 5 to perform welding operations on the weld seam to be welded.

[0059] More specifically, in this embodiment, the guide driver 43 includes a servo motor, a gear, and a rack. The servo motor is mounted on the lifting platform 31, and its output shaft is connected to the gear. The gear meshes with the rack, which is mounted on the guide platform 41. Therefore, the servo motor drives the gear to rotate around its own axis, and the gear's rotation causes the rack to move along the Y-axis, thereby moving the guide platform 41 along the Y-axis. This not only enables the guide platform 41 to move relative to the lifting platform 31 along the Y-axis but also allows for precise control of the guide platform 41's movement distance, making it more sensitive and reliable. In other embodiments, a cylinder can be used to directly drive the guide platform 41, as long as the above functions can be achieved; no further limitations are imposed here.

[0060] Specifically, such as Figure 3 and Figure 4 As shown, the guide mechanism 4 also includes a positioning shaft 44, a connecting seat 45, and a return spring 46. The two ends of the positioning shaft 44 are respectively connected to the guide table 41. The connecting seat 45 is slidably disposed on the positioning shaft 44 along the X-axis direction and is rotatably provided with a guide wheel 42. The guide wheel 42 is used to roll on the upper crossbeam. The guide wheel 42 is provided with a groove along its circumference. The upper cross rib 101 can be accommodated and abutted in the groove, thereby ensuring that the upper cross rib 101 will not detach from the guide wheel 42 during the rolling process of the guide wheel 42. When the weld to be welded is being welded, the welding mechanism 5 can always operate on the weld to be welded by guiding the upper cross rib 101 along the guide wheel 42, avoiding the upper cross rib 101 and the welding mechanism 5 from having misalignment errors that would affect the normal welding operation. The welding mechanism 5 is mounted on the connecting seat 45. When the connecting seat 45 moves along the X-axis, it causes the welding mechanism 5 to move slightly along the X-axis to adapt to the orientation of the upper transverse rib 101, thereby improving the welding effect. Both ends of the connecting seat 45 along the X-axis are abutted against the guide table 41 by return springs 46, allowing the connecting seat 45 and the welding mechanism 5 to return to their original positions under the elastic action of the return springs 46 after movement along the X-axis, and then continue to move along the extension direction of the upper transverse rib 101, further improving the welding effect.

[0061] More specifically, there are two positioning shafts 44, which are parallel to each other and spaced apart on the guide table 41. The connecting seat 45 is slidably mounted on the two positioning shafts 44 along the X-axis, ensuring that the connecting seat 45 can slide smoothly along the X-axis without rotation or shaking that would affect the welding operation. In other embodiments, the specific number of positioning shafts 44 is not limited and can be three or other numbers, as long as the above-mentioned functions can be achieved.

[0062] Specifically, such as Figure 3 and Figure 4As shown, the welding mechanism 5 also includes a welding driver and a welding torch. The output end of the welding driver is connected to the welding torch and drives the welding torch to extend, thereby performing welding operations on the weld seam, which saves manpower. It should be noted that the welding driver may include specific structures such as cylinders or electric cylinders, as long as it can achieve the above functions, no further restrictions are imposed here.

[0063] Specifically, such as Figure 3 and Figure 4 As shown, the welding device also includes a transverse rib detector 6, which is communicatively connected to the walking mechanism 2. When the transverse rib detector 6 detects the upper transverse rib 101, the walking mechanism 2 moves along the X-axis so that the guide wheel 42 is located directly above the upper transverse rib 101, so that after the guide wheel 42 moves along the Z-axis, it can press against the upper transverse rib 101, thereby facilitating the guidance of the welding operation.

[0064] More specifically, such as Figure 3 and Figure 4 As shown, the transverse rib detector 6 is mounted on the lifting platform 31 and can move up and down with the lifting platform 31. Since the frame 1 is in motion under the drive of the traveling mechanism 2 before the transverse rib detector 6 detects the upper transverse rib 101, there is a time interval between the transverse rib detector 6 sending a signal after detecting the upper transverse rib 101 and the traveling mechanism 2 driving the guide wheel 42 to stop directly above the upper transverse rib 101. Therefore, the transverse rib detector 6 and the guide wheel 42 are spaced apart along the X-axis to prevent the traveling mechanism 2 from having already driven the guide wheel 42 to miss the upper transverse rib 101 when the transverse rib detector 6 detects it. When the transverse rib detector 6 detects the upper transverse rib 101, the traveling mechanism 2 moves by a fixed offset along the X-axis. The fixed offset is the distance between the transverse rib detector 6 and the guide wheel 42 along the X-axis, ensuring that the guide wheel 42 is exactly above the upper transverse rib 101, facilitating the welding mechanism 5 to perform welding operations on the weld seam between the upper transverse rib 101 and the upper sealing rib 401.

[0065] Specifically, such as Figure 3 and Figure 4 As shown, the welding device also includes a transverse rib end detector 7, which is connected to the guide table 41 and can move along the Y-axis with the guide table 41. The transverse rib end detector 7 is communicatively connected to the welding mechanism 5. When the transverse rib end detector 7 detects the end of the upper transverse rib 101, the welding mechanism 5 moves from the starting point along the Y-axis to weld the weld seam to be welded, and then starts the welding operation from one end of the weld seam to be welded (i.e., the starting point), ensuring that the upper transverse rib 101 and the upper sealing rib 401 can be welded at the connection, further ensuring the welding effect.

[0066] More specifically, such as Figure 3 and Figure 4As shown, when the transverse rib end detector 7 detects the end of the upper transverse rib 101, the welding mechanism 5 moves a preset distance along the Y-axis. The preset distance is the connection length between the upper sealing rib 401 and the upper transverse rib 101. This saves manpower in operating the welding mechanism 5, making the welding operation more automated and more efficient and convenient.

[0067] More specifically, the welding mechanism 5 is mounted on the connecting seat 45, and the transverse rib end detector 7 is mounted on the connecting seat 45. Both are connected to the guide table 41 via the positioning shaft 44 and the connecting seat 45, ensuring a fixed distance between the welding mechanism 5 and the transverse rib end detector 7. This distance will not change due to movement of the connecting seat 45 along the X-axis. Since the welding mechanism 5 includes a welding torch, the distance between the transverse rib end detector 7 and the welding torch is also fixed. Therefore, the welding driver can directly drive the welding torch to move a fixed distance to the weld position, thereby welding the upper transverse rib 101 and the upper sealing rib 401.

[0068] Specifically, such as Figure 3 and Figure 4 As shown, the guide wheel 42, the crossbeam end detector 7, and the welding torch are all sequentially spaced on the guide table 41 along the Y-axis. The guide wheel 42, rolling on the upper crossbeam 101, guides the welding operation. The crossbeam end detector 7 detects the corresponding weld initiation point, and the welding torch extends a fixed distance to perform the welding operation on the weld seam. This arrangement makes the layout of the components more rational and the welding operation more efficient and convenient.

[0069] It should be noted that both the transverse rib detector 6 and the transverse rib end detector 7 in this embodiment can be position sensors, which have high detection sensitivity and are easy to use. In other embodiments, other components such as metal sensors can also be used, as long as they can achieve the above-mentioned functions, and no further limitations are imposed here. In addition, the fixed offset, fixed distance, preset distance, and other distances mentioned in this embodiment are all determined by detection by corresponding detectors or preset methods, and the control unit (such as CPU) receives the signal and issues instructions to the corresponding driver to perform the corresponding welding action. Those skilled in the art are clear about the specific principles, and they will not be described in detail here.

[0070] like Figures 1-4 As shown, this embodiment also provides a welding method using the above-mentioned welding apparatus, specifically including the following steps:

[0071] Step 1: The walking mechanism 2 drives the frame 1 to move along the X-axis. When the transverse rib detector 6 detects the upper transverse rib 101, the walking mechanism 2 moves along the X-axis by a fixed offset to move the guide wheel 42 directly above the upper transverse rib 101.

[0072] In step one above, the welding device is first placed on one side of the steel cage. The frame 1 is driven to move along the X-axis by the walking mechanism 2. Since the guide wheel 42 and the transverse rib detector 6 are spaced apart in the X-axis direction, when the transverse rib detector 6 detects the upper transverse rib 101, it will send a signal to the walking mechanism 2. After receiving the signal, the walking mechanism 2 will continue to drive the frame 1 to move along the X-axis by a fixed offset, so that the guide wheel 42 is directly above the upper transverse rib 101. At this time, the driving of the frame 1 is stopped so that the guide wheel 42 can abut against the upper transverse rib 101 during the downward pressing process. At the same time, the welding torch of the welding mechanism 5 is exactly directly above the weld to be welded, which facilitates the welding operation.

[0073] Step 2: The lifting driver 32 drives the lifting platform 31 to move along the Z-axis so that the guide wheel 42 abuts against the upper horizontal rib 101.

[0074] In step two above, the piston rod of the cylinder extends to drive the lifting platform 31 to descend, thereby causing the groove on the guide wheel 42 to abut against the upper horizontal rib 101, thus guiding the welding operation of the upper horizontal rib 101 and preventing welding deviation.

[0075] Step 3: The guide table 41 moves relative to the lifting table 31 along the Y-axis to drive the guide wheel 42, the welding mechanism 5 and the transverse rib end detector 7 to move. When the transverse rib end detector 7 detects the end of the upper transverse rib 101, the welding driver drives the welding torch to extend to the starting point.

[0076] In step three above, the servo motor drives the gear to rotate, the gear rotation drives the rack to move, and the rack movement drives the guide table 41 to move relative to the lifting table 31 along the Y-axis direction, so that the guide wheel 42, the welding mechanism 5 and the transverse rib end detector 7 move synchronously along the Y-axis direction. When the transverse rib end detector 7 detects the end of the upper transverse rib 101, the welding driver drives the welding gun to extend a fixed distance until the output end of the welding gun moves to the starting point of the weld to be welded (the starting point is the end of the upper transverse rib 101 and the upper sealing rib 401 to be welded facing this device) and the welding operation begins.

[0077] Step 4: The guide table 41 drives the welding torch to move a preset distance from the starting point along the Y-axis to weld the weld seam to be welded. During this process, the guide wheel 42 is rolled on the upper horizontal rib 101, and the connecting seat 45 drives the welding torch to move along the X-axis.

[0078] In step four above, the preset distance is the connection length of the upper sealing rib 401 and the upper horizontal rib 101 extending along the Y-axis direction. This ensures that the connection between the upper horizontal rib 101 and the upper sealing rib 401 can be welded, thereby ensuring the connection strength between the two. When the upper horizontal rib 101 and the welding mechanism 5 have an offset error that affects the normal welding operation, since the welding mechanism 5 is set on the connecting seat 45, when the connecting seat 45 moves along the X-axis direction, it will drive the welding mechanism 5 to move slightly along the X-axis direction to adapt to the direction of the upper horizontal rib 101, thereby better welding the weld seam to be welded.

[0079] Step 5: The welding torch, lifting platform 31 and guide platform 41 move to their initial positions respectively. The traveling mechanism 2 and the transverse rib detector 6 cooperate with each other to move the frame 1 to the next welding position.

[0080] In step five above, the welding driver drives the welding torch to retract, the lifting driver 32 drives the lifting platform 31 to rise, and the guide driver 43 drives the guide platform 41 to move in the direction away from the rebar cage until the above components return to the initial position. The traveling mechanism 2 drives the frame 1 to move along the X-axis until the transverse rib detector 6 detects the next upper transverse rib 101, so that the frame 1 stops and the guide wheel 42 is located directly above the upper transverse rib 101, which facilitates the next welding operation.

[0081] It should be noted that, through the above settings, the welding device of this embodiment can automatically identify the position of the weld to be welded through the corresponding detector and automatically perform welding. After the welding operation is completed, it can automatically perform the next weld to be welded point search and welding work, realizing the automation of the welding process and further improving the weld quality.
