[0019] It should be noted that the terms "first", "second", and the like in the above drawings of the specification and claims of the present application are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0020] In combination Figures 1 to 3 As shown, the embodiments of the present application provide a steel reinforcement cage welding device, which comprises: a rack 100; a docking clamp jaw 200 connected with the rack 100, the docking clamp jaw 200 being used to clamp a stirrup single piece 300; a welding assembly 400 connected with the rack 100, the welding assembly 400 being configured to be movable along the arrangement direction of a plurality of preset welding point positions, the plurality of preset welding point positions being the positions for welding the stirrup single piece 300 clamped by the docking clamp jaw 200 and a plurality of through-length bars 500; The lengthwise tendon traction mechanism connected with the rack 100 includes a clamping state and an empty load reset state. In the clamping state, the lengthwise tendon traction mechanism clamps a plurality of lengthwise tendons 500 by a preset distance along the conveying direction of the lengthwise tendons 500. In the empty load reset state, the lengthwise tendon traction mechanism moves away from the lengthwise tendons 500 by a preset distance along the conveying direction, and the preset distance is equal to the straight-line distance between two adjacent stirrup single pieces 300 in the finished steel reinforcement cage.

[0021] Specifically, the rack 100 can be formed by welding, casting or assembling steel materials, for example, using a rectangular frame structure or a truss structure, such as Figures 1 to 3 As described above, the rack 100 has a whole hexagonal frame structure, and a product channel is formed in the middle of the rack 100 in the length direction. In the embodiment, the conveying direction is the positive direction of the Y-axis. With the Y-axis direction as the reference, the end of the rack 100 facing the negative direction of the Y-axis is the inlet end, and the end facing the positive direction of the Y-axis is the outlet end. The butt clamping jaw 200 can include a pneumatic clamping jaw, a hydraulic clamping jaw or an electric clamping jaw, and the clamping action is controlled by a driving device, for example, using a solenoid valve to switch the gas circuit to realize the opening and closing action of the pneumatic clamping jaw, or through a motor to drive a gear rack mechanism to realize the movement of the clamping jaw. The butt clamping jaw 200 is assembled on the rack 100 and located at the inlet end of the rack 100. The welding assembly 400 is a welding device, which can move along the preset welding point position through a slide rail cooperating with a linear motor, a lead screw transmission or a synchronous belt transmission, such as Figure 4 As shown in the figure, the shape of the stirrup single piece 300 is similar to an inverted trapezoidal shape, and the long side of the inverted trapezoidal shape needs to be welded with a plurality of lengthwise tendons 500, and the two waist sides of the inverted trapezoidal shape need to be welded with a plurality of lengthwise tendons 500. Therefore, a plurality of welding point positions are arranged on the long side in the extension direction of the long side, and a plurality of welding point positions are also arranged on each waist side in the extension direction of the waist side. The clamping state and the empty load reset state of the lengthwise tendon traction mechanism can be realized by a mechanical linkage mechanism, a cylinder drive or a motor drive, for example, using a double-acting cylinder to push the clamping jaw to complete the clamping and releasing actions, and the movement distance is controlled by a limit switch.

[0022] The welding process of the reinforcing cage welding equipment in the embodiment is as follows: the frame 100 is fixed to provide stable support and is aligned with the conveying line. The stirrup single piece 300 is first conveyed to the entrance end of the frame 100, and then the butt clamping jaw 200 clamps the first stirrup single piece 300, and the first stirrup single piece 300 is kept in a stable state to ensure the stability of subsequent welding. During the clamping process of the butt clamping jaw 200, the through bar traction mechanism is in an empty load reset state. Then, a plurality of through bars 500 are conveyed to the entrance end of the frame 100, at this time, the through bar traction mechanism is switched to a clamping state, in the clamping state, the through bar traction mechanism clamps and feeds the through bars 500 by a preset distance in the conveying direction of the through bars 500, and the preset distance can be the straight line distance between two adjacent stirrup single pieces 300 in the finished reinforcing cage. Under the traction of the through bar traction mechanism, the plurality of through bars 500 are conveyed into the area surrounded by the first stirrup single piece 300, and each through bar 500 is accurately aligned with the corresponding welding point on the first stirrup single piece 300. Finally, the welding assembly 400 moves along the plurality of preset welding points of the first stirrup single piece 300, and sequentially welds the plurality of welding points to complete the welding of the first stirrup single piece 300 and the plurality of through bars 500. After the first stirrup single piece 300 is welded, the butt clamping jaw 200 releases the clamping of the first stirrup single piece 300 and resets, the through bar traction mechanism is switched to an empty load reset state, and moves by a preset distance in the direction away from the conveying direction of the through bars 500 to reset. After the butt clamping jaw 200 clamps the second stirrup single piece 300 conveyed, the through bar traction mechanism is switched to the clamping state again, and moves by a preset distance in the conveying direction after the plurality of through bars 500 are pulled again, and the welding assembly 400 moves along the plurality of preset welding points of the second stirrup single piece 300, and sequentially welds the plurality of welding points to complete the welding of the second stirrup single piece 300 and the plurality of through bars 500. Repeat the above process until the welding of the reinforcing cage is completed.

[0023] Therefore, in the embodiment, the docking clamping jaw 200, the welding assembly 400 and the length-through bar traction mechanism are all connected with the rack 100, and the rack 100 can provide a stable support platform to ensure the stable operation of the welding process. The docking clamping jaw 200 can clamp the delivered stirrup single piece 300, thereby improving the switching efficiency of the stirrup single piece 300. During the welding process, the docking clamping jaw 200 can fix the position of the stirrup single piece 300 to prevent it from deviating, thereby ensuring the accurate positioning of the welding points and further ensuring the welding quality. The welding assembly 400 can automatically position and perform the welding operation by moving along the arrangement direction of the plurality of preset welding points, thereby reducing the manual intervention and improving the consistency and efficiency of the welding. The length-through bar traction mechanism can clamp the length-through bar 500 by a preset distance along the conveying direction of the length-through bar 500 in the clamping state, thereby ensuring that the welding position of each length-through bar 500 can be accurately aligned with the welding points on each stirrup single piece 300, and ensuring the welding precision of the plurality of length-through bars 500. The length-through bar traction mechanism can move by a preset distance away from the conveying direction of the length-through bar 500 in the empty load reset state, thereby realizing the quick reset. In this way, during the welding process, each stirrup single piece 300 can be accurately welded with the plurality of length-through bars 500, forming a continuous and efficient welding process, thereby improving the welding precision and efficiency of the reinforcement cage, and further solving the problems of poor precision and low efficiency caused by inaccurate positioning and complicated operation in the traditional reinforcement cage welding.

[0024] Optionally, the length-through bar traction mechanism comprises a length-through bar clamping jaw, a sliding track and a driving structure. The driving structure is connected with the rack 100. The sliding track is connected with the rack 100 and extends along the conveying direction. The length-through bar clamping jaw is provided with a plurality of length-through bar clamping jaws, each of which clamps one length-through bar 500. The connecting end of the length-through bar clamping jaw is slidably connected with the sliding track. The driving structure is used to drive the plurality of length-through bar clamping jaws to reciprocally slide along the sliding track, and the sliding distance is a preset distance. The clamping end of the length-through bar clamping jaw clamps the length-through bar 500 in the clamping state, and releases the clamping of the length-through bar 500 in the empty load reset state.

[0025] Specifically, the structural composition of the length-through bar traction mechanism is similar to that of the semi-finished product traction structure 900 mentioned later. The length-through bar traction mechanism realizes the traction of the plurality of length-through bars 500 to the welding station, and the semi-finished product traction structure 900 mentioned later realizes the traction of the welded stirrup single piece 300 to the outside of the welding station. The welding station is the position of the welding assembly 400 during welding. Exemplarily, the length-through bar clamping jaw can adopt a pneumatic clamping jaw, a hydraulic clamping jaw or an electric clamping jaw. The sliding track can adopt a linear guide rail, a ball screw pair or a synchronous belt transmission structure. The driving structure can adopt a servo motor, a stepping motor or a linear motor.

[0026] In the empty reset state, the clamping end of the through tendon clamp jaw is in the open state, the driving structure drives the through tendon clamp jaw to move away from the rack 100, that is, away from the conveying direction along the sliding track, and stops at any position. In this state, the through tendon clamp jaw can clamp the through tendon 500.

[0027] In the clamping state, the clamping end of the through tendon clamp jaw is in the closed state, and the clamping end of each through tendon clamp jaw clamps a through tendon 500. Then, the driving structure drives the through tendon clamp jaw to move towards the rack 100, that is, towards the conveying direction along the sliding track, so that the welding position on each through tendon 500 is aligned with the corresponding welding point. Further, the end of the through tendon 500 towards the rack 100 is the first end of the through tendon 500, and there is a certain distance between the clamping position of the clamping end of the through tendon clamp jaw and the first end of the through tendon 500, so as to avoid interference of the clamping end of the through tendon clamp jaw with the welding of the welding point. After the welding of each stirrup single piece 300 is completed, the state is switched to the empty reset state, the clamping end of the through tendon clamp jaw is released, and the reverse dragging or friction damage to the through tendon 500 in the reset stage is avoided. The through tendon 500 is clamped and conveyed again after reset, until the welding of a reinforcement cage is completed.

[0028] In this way, by extending the sliding track along the conveying direction and stably connecting it with the rack 100, and by slidingly connecting the sliding track with the through tendon clamp jaw, a precise straight-line guide path is provided for the through tendon clamp jaw, ensuring the accuracy of the pulling direction of the through tendon 500. By directly fixing the driving structure with the rack 100, and by controlling the output power of the driving structure to drive the through tendon clamp jaw to reciprocally slide along the sliding track with a sliding distance equal to a preset distance, it is further ensured that the moving distance of the through tendon clamp jaw is consistent with the straight-line distance between every two stirrup single pieces 300 in the reinforcement cage, so as to reduce the pulling error, thereby accurately controlling the conveying distance and position of the through tendon 500 during welding, improving the welding precision, and solving the problem of insufficient precision caused by positioning deviation in the traditional reinforcement cage welding process.

[0029] In some embodiments, whether there is a through tendon 500 can be determined by visual recognition, and whether the through tendon clamp jaw clamps the through tendon 500 can also be determined by visual recognition. For example, whether there is a through tendon 500 can be determined by shooting with a camera, and whether the clamping end of the through tendon clamp jaw accurately clamps at a specified position of the through tendon 500 can also be determined by the camera. The above processes can be realized by existing means, and no specific requirements are made.

[0030] Optionally, the reinforcement cage welding equipment further comprises a first driving assembly 600 and a second driving assembly 700. The second driving assembly 700 is connected with the rack 100 and drives the first driving assembly 600 to move vertically. The first driving assembly 600 is drivingly connected with the butt clamp jaw 200 and drives the butt clamp jaw 200 to reciprocally move in the conveying direction.

[0031] Specifically, the first driving assembly 600 can realize the reciprocating movement of the butt joint clamping jaw 200 in the conveying direction, the second driving assembly 700 can drive the device for moving the first driving assembly 600 vertically, and the first driving assembly 600 and the second driving assembly 700 can both adopt a screw mechanism, a gear and rack mechanism or a linear guide rail cooperating with a driving motor and the like.

[0032] In this way, the second driving assembly 700 is connected with the rack 100 and drives the first driving assembly 600 to move vertically, and the first driving assembly 600 is drivingly connected with the butt joint clamping jaw 200 and drives the butt joint clamping jaw 200 to reciprocate in the conveying direction, so that the clamping position of the butt joint clamping jaw 200 can be adaptively adjusted according to the actual welding height, thereby improving the use flexibility of the butt joint clamping jaw 200.

[0033] Optionally, in combination with the descriptions in Figure 1 , Figure 2 and Figure 4 , the welding assembly 400 includes a first welding structure 410 and a second welding structure 420, the stirrup single piece 300 includes a horizontal section and two inclined sections connected with the horizontal section, the first welding structure 410 is movably arranged on the rack 100 along the extension direction of the horizontal section, and the two second welding structures 420 are movably arranged on the rack 100 along the extension directions of the two inclined sections, respectively.

[0034] Specifically, as shown in Figure 4 , the stirrup single piece 300 includes a first horizontal section with a relatively long length, a second horizontal section with a relatively short length, and two inclined sections connected between the first horizontal section and the second horizontal section, the horizontal section in the embodiment refers to the first horizontal section with the relatively long length, and the first horizontal section is provided with welding points for welding with the plurality of through-length stirrups 500 during actual welding. The first welding structure 410 is provided with two, and the two first welding structures 410 are located at the top of the rack 100 and can move towards or away from each other along the X-axis direction. The second welding structure 420 is provided with two, and the two second welding structures 420 are movably arranged on the rack 100, respectively, each second welding structure 420 corresponds to an inclined section and can move along the inclined direction of the inclined section. During welding, the two first welding structures 410 move towards each other to shorten the welding time of the first horizontal section with the through-length stirrups 500. At the same time, the two second welding structures 420 move obliquely to enable the corresponding inclined sections to be welded with the plurality of through-length stirrups 500, respectively. The first welding structure 410 and the second welding structure 420 can adopt the same welding equipment, for example, the first welding structure 410 and the second welding structure 420 can both adopt an automatic welding robot with visual recognition.

[0035] In this way, by moving the first welding structure 410 along the extension direction of the horizontal section, the first welding structure 410 is arranged on the frame 100, and the first welding structure 410 is arranged on the frame 100. The connection mode of the frame 100 ensures the stability of the welding path, thereby maintaining the continuity and consistency of the welding points on the horizontal section. By moving the second welding structure 420 along the extension direction of the inclined section, the second welding structure 420 is arranged on the frame 100, and the first welding structure 410 and the second welding structure 420 are independent and do not interfere with each other, so that the welding of the horizontal section and the inclined section can be carried out at the same time, thereby improving the welding efficiency.

[0036] Optionally, in combination with Figure 1 As shown, the frame 100 includes a frame body 110 and two sets of welding supports corresponding to the two second welding structures 420; each set of welding supports includes a vertical telescopic structure 120, a support slide rail 130, and a vertical column 140. The lower end of the vertical column 140 is connected with the frame body 110, the upper end of the vertical column 140 is rotationally connected with one end of the support slide rail 130, the other end of the support slide rail 130 is hingedly connected with the driving end of the vertical telescopic structure 120, the fixed end of the vertical telescopic structure 120 is hingedly connected with the frame body 110, and the vertical telescopic structure 120 is used to drive the support slide rail 130 to rotate about the rotationally connected axis of the support slide rail 130 and the vertical column 140. The second welding structure 420 is movably arranged on the corresponding support slide rail 130.

[0037] Specifically, the vertical telescopic structure 120, the support slide rail 130, and the vertical column 140 are one-to-one corresponding and are provided in two sets. Taking the set located on the negative direction of the X-axis as an example, the vertical telescopic structure 120 can adopt a hydraulic cylinder, a pneumatic cylinder, or an electric push rod. The vertical column 140 is close to the center line of the frame body 110, the lower end of the vertical column 140 is fixedly connected with the frame body 110, the upper end of the vertical column 140 is rotationally connected with the right end of the support slide rail 130, the left end of the support slide rail 130 is hingedly connected with the driving end of the vertical telescopic structure 120, the fixed end of the vertical telescopic structure 120 is hingedly connected with the frame body 110, and the second welding structure 420 is movably arranged on the support slide rail 130. Before welding, the driving end of the vertical telescopic structure 120 drives the left end of the support slide rail 130 to move upward, and since the right end of the support slide rail 130 is rotationally connected with the upper end of the vertical column 140, the support slide rail 130 is inclined, so that the support slide rail 130 is parallel to the inclined section of the hoop single piece 300. During welding, the second welding structure 420 can move under the constraint of the support slide rail 130 to weld the welding points distributed on the inclined section.

[0038] Thus, the lower end of the vertical column 140 is fixed to the rack body 110 to ensure the stability of the base, and the upper end of the vertical column 140 is rotatably connected to one end of the support slide rail 130 to provide a rotation fulcrum for the support slide rail 130, allowing the support slide rail 130 to rotate freely around the axis, and the other end of the support slide rail 130 is hingedly connected to the driving end of the vertical telescopic structure 120, while the fixed end of the vertical telescopic structure 120 is hingedly connected to the rack body 110, which can convert the linear motion of the vertical telescopic structure 120 into the rotational motion of the support slide rail 130. When the driving end of the vertical telescopic structure 120 is telescoped, the support slide rail 130 rotates around the rotation axis of the vertical column 140 according to the displacement of the driving end, thereby adjusting the inclination angle of the support slide rail 130 in real time. The second welding structure 420 is moved on the support slide rail 130, and the second welding structure 420 can adapt to the actual trend of the inclined section of the stirrup single piece 300 according to the change of the angle of the support slide rail 130, thereby ensuring that the second welding structure 420 always follows the trajectory of the inclined section during movement to improve the quality of inclined welding.

[0039] Optionally, in combination with Figure 1 As shown, the reinforcement cage welding equipment further comprises a through-bar guiding structure 800, which comprises a support seat 810 connected with the rack 100, and a plurality of vertical rods 811 connected with the support seat 810. Each vertical rod 820 is provided with two positioning groove structures 812 spaced vertically, and each positioning groove structure 812 is used to correspond to a through-bar 500 slidingly passing through.

[0040] Specifically, each positioning groove structure 812 corresponds to a welding point, and one positioning groove structure 812 also corresponds to one through-bar 500. During welding, each through-bar 500 can slide in the corresponding positioning groove structure 812, and the positioning groove structure 812 constrains the through-bar 500 to ensure that the through-bar 500 only moves in the conveying direction and does not deviate.

[0041] Thus, the plurality of vertical rods 811 connected with the support seat 810 ensure the overall stability of the guiding structure through the rigid connection of the support seat 810 and the rack 100, and each vertical rod 811 is provided with two positioning groove structures 812, each of which is slidingly connected with a through-bar 500. The positioning groove structure 812 can constrain the movement of the through-bar 500 to ensure that the through-bar 500 can be accurately conveyed to the corresponding welding point, thereby improving the welding quality.

[0042] Optionally, the support base 810 includes a first frame 810, a second frame 820, and a power structure 830. The second frame 820 is connected to the frame 100. The first frame 810 and the second frame 820 are vertically slidably connected. Multiple vertical rods 811 are vertically arranged on the first frame 810. The power structure 830 drives the first frame 810 to slide vertically.

[0043] Specifically, the first frame 810 is located above the second frame 820, which is connected to the machine frame 100. The first frame 810 and the second frame 820 are vertically slidably connected. The power structure 830 can be a linear drive device such as a hydraulic cylinder, a pneumatic cylinder, or an electric push rod. During welding, the drive structure 830 drives the first frame 810 to move vertically to adjust the height of multiple vertical rods 811, thereby adjusting the height of the two positioning groove structures 812 on each vertical rod 811 to align with the corresponding longitudinal rib 500.

[0044] Thus, the second frame 820 is connected to the frame 100, and the frame 100 constrains the second frame 820 to ensure its stability. The first frame 810 is vertically slidably connected to the second frame 820, and multiple vertical rods 811 are vertically set on the first frame 810. The power structure 830 drives the first frame 810 to slide vertically, so that the multiple vertical rods 820 rise and fall synchronously with the first frame 810, ensuring that the through rib 500 always maintains a precise position during the conveying process, thereby improving welding accuracy and production efficiency.

[0045] In some embodiments, multiple vertical rods 811 are detachably connected to the first frame 810, and the height of each positioning groove structure 812 is adjustable to accommodate welding of steel cages of different shapes.

[0046] Optionally, combined Figure 2 As shown, the rebar cage welding equipment also includes a semi-finished product traction structure 900. The semi-finished product traction structure 900 is located at the outlet end of the frame 100 and includes a traction gripper 910, a connecting beam 920, and a drive assembly. The connecting beam 920 is arranged perpendicular to the conveying direction and is movably arranged on the frame 100 along the conveying direction. The traction gripper 910 is arranged on the connecting beam 920 and is used to clamp the welded stirrup pieces 300. The drive assembly is used to drive the connecting beam 920 to reciprocate along the conveying direction, and the traction gripper 910 is used to dock with downstream equipment.

[0047] Specifically, the semi-finished product traction structure 900 is located at one end of the rack 100 towards the positive direction of the Y axis, that is, the outlet end of the rack 100. The traction clamping jaw 910 clamps one hoop single piece 300 after welding and is connected with the downstream equipment. The downstream equipment can be understood as a finished product conveying roller. The driving assembly (not shown in the figure) can adopt a servo motor or a cylinder driving structure. The connecting beam 920 is connected with the rack 100 through a gear rack or a sliding rail slider, so that the connecting beam 920 has the ability to move along the Y axis direction. The traction clamping jaw 910 is distributed along the length direction of the connecting beam 920, and each traction clamping jaw 910 is equipped with an independent driving member, so that each traction clamping jaw 910 can clamp or open.

[0048] In the welding process, when the first hoop single piece 300 is welded with the plurality of longitudinal reinforcement bars 500, the longitudinal reinforcement bar clamping jaw is reset for the first time, that is, moves a preset distance away from the conveying direction.

[0049] In the welding of the second hoop single piece 300, the longitudinal reinforcement bar clamping jaw clamps the longitudinal reinforcement bar 500 and moves a preset distance along the conveying direction for the second time. In the process of the second movement of the longitudinal reinforcement bar clamping jaw along the conveying direction, the first hoop single piece 300 is also moved a preset distance along the conveying direction under the driving of the longitudinal reinforcement bar 500, and is clamped by the traction clamping jaw 910 after the preset distance. When the second hoop single piece 300 is welded, the longitudinal reinforcement bar clamping jaw is reset for the second time.

[0050] When the third hoop single piece 300 is welded, the longitudinal reinforcement bar clamping jaw moves a preset distance along the conveying direction for the third time, and in the process of the third movement of the longitudinal reinforcement bar clamping jaw along the conveying direction, the traction clamping jaw 910 also moves a preset distance along the conveying direction in the state of clamping the first hoop single piece 300, that is, the traction clamping jaw 910 and the longitudinal reinforcement bar clamping jaw move synchronously. The traction clamping jaw 910 connects the first hoop single piece 300 to the downstream equipment for temporary storage, and then the traction clamping jaw 910 is reset (the connecting beam 920 is driven by the driving assembly to move along the negative direction of the Y axis (away from the conveying direction)) and clamps the second hoop single piece 300. After the third hoop single piece 300 is welded, the longitudinal reinforcement bar clamping jaw is reset.

[0051] When the fourth stirrup piece 300 is welded, the long-strength steel clamping jaw is moved for the fourth time in the conveying direction, and during the movement of the long-strength steel clamping jaw for the fourth time in the conveying direction, the pulling clamping jaw 910 is also moved in the conveying direction by a preset distance in the state of clamping the second stirrup piece 300, and the pulling clamping jaw 910 transfers the second stirrup piece 300 to the downstream equipment, and then the pulling clamping jaw 910 is reset and clamps the third stirrup piece 300. After the welding of the fourth stirrup piece 300 is completed, the long-strength steel clamping jaw is reset. In this way, the cycle is repeated until the welding of all the stirrup pieces 300 of the reinforcement cage is completed, so as to avoid the interference of the welded stirrup piece 300 with the continuity of the welding.

[0052] In this way, by arranging the semi-finished product pulling structure 900 at the outlet end of the rack 100, and moving the two ends of the connecting beam 920 arranged in the rack 100 respectively, under the constraint of the rack 100, the connecting beam 920 always maintains a parallel motion state during the movement, so as to ensure the clamping accuracy of the pulling clamping jaw 910. By driving the connecting beam 920 to move back and forth in the conveying direction through the driving assembly, the efficient forward movement and rapid reset of the pulling clamping jaw 910 can be realized, the continuity of the semi-finished product conveying is ensured, the seamless transfer of the welded finished product is realized through the butt joint of the pulling clamping jaw 910 and the downstream equipment, the manual handling link is eliminated, and the continuity of the production process is ensured.

[0053] Optionally, the reinforcement cage welding equipment further comprises a control device, which is in communication connection with the butt clamping jaw 200, the welding assembly 400 and the long-strength steel pulling mechanism respectively.

[0054] Specifically, the control device is in communication connection with the butt clamping jaw 200, so that the clamping and conveying process of the stirrup piece 300 can be dynamically adjusted according to the welding progress, so as to avoid the positioning deviation of the stirrup caused by improper clamping time, thereby ensuring the stable positioning of the stirrup piece 300 at the preset position. At the same time, the control device is in communication connection with the welding assembly 400, so as to realize the accurate tracking and movement control of the welding position. The welding assembly 400 can automatically calibrate the trajectory according to the real-time relative position of the stirrup piece 300 and the long-strength steel 500, so as to ensure that the welding operation is performed at the correct coordinates, and eliminate the virtual welding or missed welding phenomenon caused by movement errors. In addition, the control device is in communication connection with the long-strength steel pulling mechanism, so that the clamping and resetting actions of the long-strength steel 500 are strictly matched with the welding rhythm. After the long-strength steel 500 is pushed to the specified distance in the clamping state, the pulling mechanism can return to the original position in the empty load reset state in time, so as to prevent the steel misalignment problem caused by excessive or insufficient conveying of the long-strength steel 500.

[0055] Thus, by controlling the device respectively with the docking jaw 200, the welding assembly 400 and the length of the tendon traction mechanism communication connection, the control device, the docking jaw 200, the welding assembly 400 and the length of the tendon traction mechanism communication system is established, which can realize centralized management and timing control, ensure that the operation between each mechanism can be carried out in order according to the predetermined logic, thereby greatly improving the welding efficiency and the stability of the finished product quality.

[0056] Optionally, the reinforcing cage welding equipment further comprises a third driving assembly connected between the second driving assembly 700 and the docking jaw 200, the third driving assembly drives the docking jaw 200 to move in the transverse direction, and the transverse direction, the vertical direction and the conveying direction are perpendicular to each other.

[0057] Specifically, the transverse direction refers to the X-axis direction, the vertical direction refers to the Z-axis direction, and the conveying direction refers to the Y-axis direction. The transverse direction, the vertical direction and the conveying direction are perpendicular to each other. The first adjusting mechanism refers to a device for adjusting the position of the docking jaw 200, which can adopt a linear motor, a hydraulic cylinder or a pneumatic push rod to realize the driving mode of transverse movement. The third driving assembly can adopt a ball screw transmission, a gas cylinder or a gear and rack transmission, for example, the third driving assembly adopts a gas cylinder, the gas cylinder is telescopic along the X-axis direction, the cylinder body of the gas cylinder is connected with the driving end of the second driving assembly 700, and the driving end of the gas cylinder is drivingly connected with the docking jaw 200. The second driving assembly 700 can drive the gas cylinder and the docking jaw 200 to move in the conveying direction.

[0058] During the docking process, the first driving assembly 600 adjusts the vertical position of the docking jaw 200, so that the height of the docking jaw 200 meets the docking requirements, and then the third driving assembly adjusts the transverse position of the docking jaw 200, so that the clamping end of the docking jaw 200 can accurately align the hoop single piece 300, and then the second driving assembly 700 adjusts the position of the docking jaw 200 in the conveying direction, so that the docking jaw 200 can accurately clamp the hoop single piece 300. When welding, after the current hoop single piece 300 is welded with the length of tendon 500, the third driving assembly can be transversely retracted, and the docking jaw 200 is away from the single signed hoop single piece 300, and then the second driving assembly 700 can move the docking jaw 200 to the next hoop single piece 300, and the third driving assembly is transversely elongated to accurately clamp the next hoop single piece 300, ensuring the continuity of welding.

[0059] Thus, the third driving assembly is connected between the second driving assembly 700 and the docking clamp jaw 200, and drives the docking clamp jaw 200 to move in the transverse direction, which is perpendicular to the vertical direction and the conveying direction, and the third driving assembly can realize the transverse movement based on the vertical movement of the frame of the second driving assembly 700, and can allow fine transverse position fine adjustment of the stirrup single piece 300 before welding, effectively compensate for the deviation caused by material deformation or manufacturing error, and the design that the transverse direction, the vertical direction and the conveying direction are perpendicular to each other forms an orthogonal coordinate system, which significantly improves the alignment accuracy of the stirrup single piece 300 and the through-length bar 500, thereby guaranteeing the stability of the welding process and the quality of the finished product.

Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application, and these changes and modifications shall fall within the protection scope of the present application.
