Description

Technical Field

[0001] This application relates to the field of T-beam positioning mesh processing technology, and in particular to a production line and method for processing prestressed tendon positioning mesh for highly flexible precast T-beams. Background Technology

[0002] The prestressed tendon positioning net for precast T-beams consists of a web positioning net (including short and long web positioning bars), a base slab positioning net (including short and long base slab positioning bars), and height positioning bars. During fabrication, the position of the height positioning bars is adjusted according to the height of the prestressed tendons at different locations. Currently, the conventional fabrication process for prestressed T-beam positioning nets involves first cutting the reinforcing bars to the required length, then manually placing the bars on the positioning net mold, and finally welding or binding the intersections of the reinforcing bars for fixation.

[0003] Different models of positioning nets require different molds for production, resulting in a wide variety of molds. Changing molds when producing different positioning nets is extremely inefficient. Furthermore, the current manual positioning and welding processes are labor-intensive and prone to human error, which severely restricts the high-quality and efficient production of T-beam prestressed tendon positioning nets.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Summary of the Invention

[0038] This application also provides a method for processing a prestressed tendon positioning mesh for highly flexible precast T-beams. The processing method utilizes the aforementioned production line for processing prestressed tendon positioning mesh for highly flexible precast T-beams, and includes the following steps:

[0039] Step 1: The straightening and cutting machine cuts the steel bars into short bars required for the web positioning mesh and the bottom plate positioning mesh, and then feeds the short bars onto the bar feeding mechanism.

[0040] The short ribs of the web positioning mesh are fed into the first pusher machine through the first slide by the rib feeding mechanism, and the short ribs of the bottom plate positioning mesh are fed into the second pusher machine through the second slide by the rib feeding mechanism.

[0041] Step 2: The first pusher starts and sends the short rib to the first short rib buffer chain for temporary storage; the second pusher starts and sends the short rib to the second short rib buffer chain for temporary storage.

[0042] At the same time, the straightening and cutting machine successively feeds the long ribs of the web plate positioning net and the long ribs of the bottom plate positioning net. The feeding mechanism conveys the long ribs forward, and the long rib centering mechanism centers the long ribs. Then, the long rib pushing mechanism pushes the long ribs into the long rib dropping platform, and the long ribs slide down from the long rib dropping platform to the long rib buffer chain for temporary storage.

[0043] Step 3: The short rib feeding mechanism first grabs multiple short ribs on the first short rib buffer chain using the short rib gripper, and then places the multiple short ribs on multiple second pitch adjustment components on the bracket mechanism;

[0044] Then, the long rib feeding mechanism grabs multiple long ribs on the long rib buffer chain through the long rib gripper and places the multiple long ribs on multiple second pitch adjustment components on the bracket mechanism;

[0045] Step 4: The welding machine in the welding mechanism is positioned to weld the intersection of the long and short ribs in Step 3 to form the web positioning mesh.

[0046] At the same time, the short rib feeding mechanism grabs multiple short ribs on the second short rib buffer chain through the short rib gripper and places the multiple short ribs on multiple first pitch adjustment components on the bracket mechanism;

[0047] The long rib feeding mechanism grabs multiple long ribs from the long rib buffer chain using a long rib gripper and places the multiple long ribs on multiple first pitch adjustment components on the bracket mechanism;

[0048] Step 5: The welding machine in the welding mechanism is in place, and the intersection of the long and short ribs in Step 4 is welded to form two sets of base plate positioning mesh.

[0049] The transfer mechanism picks up the web positioning mesh using a transfer gripper and places it on the web positioning assembly of the welding station;

[0050] Simultaneously, the straightening and cutting machine performs the next round of rebar cutting, and the rebar feeding mechanism begins the next cycle.

[0051] Step 6: The transfer mechanism picks up the base plate positioning mesh twice using the transfer gripper and places it on the base plate positioning assembly of the welding station;

[0052] At the same time, the grasping and laying of the short and long ribs of the web positioning net will be carried out in the next round.

[0053] Step 7: The welding machine in the welding mechanism is in place, and the bottom plate positioning mesh and the web plate positioning mesh in Step 6 are welded together to form the T-beam positioning mesh;

[0054] Step 8: The transfer gripper in the transfer mechanism picks up the T-beam positioning net on the welding table and transfers it to the buffer rack for temporary storage.

[0055] Simultaneously, welding of the web positioning mesh and grasping and placing of the short and long ribs of the base plate positioning mesh are carried out.

[0057] In this processing line, the buffer chain is positioned close to the bracket frame, the feeding mechanism is positioned close to the buffer chain, and the welding mechanism is positioned close to the bracket frame and welding station. This results in a reasonable distribution of the various mechanisms in the processing line, a more compact layout, and a smaller footprint. The various processes are seamlessly connected, enabling continuous production of T-beam positioning nets. Furthermore, by adjusting the components in this processing line, it can produce T-beam positioning nets of different sizes and specifications, greatly improving the production efficiency of the processing line.

[0085] The present application will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present application can be combined with each other.

[0086] According to specific embodiments of this application, such as Figure 1-10 As shown, this application provides a processing line for prestressed tendon positioning mesh of highly flexible precast T-beams, the processing line including:

[0087] Straightening and cutting machine 1 is used to cut steel bars into short bars or long bars of a set length.

[0088] The feeding mechanism 11 is located downstream of the straightening and cutting machine 1 and is used to feed short or long ribs. In this embodiment, the feeding mechanism 11 is a conveying chain, which is located downstream of the outlet of the straightening and cutting machine 1, and the extension direction of the feeding mechanism 11 is parallel to the discharge direction of the straightening and cutting machine 1.

[0089] A short rib buffer mechanism 10 and a long rib buffer mechanism 2 are provided on one side of the rib feeding mechanism 11; the short rib buffer mechanism 10 includes multiple sets of short rib buffer chains for buffering short ribs; the long rib buffer mechanism 2 includes multiple sets of long rib buffer chains 21 for buffering long ribs.

[0090] A bracket mechanism 3 and a welding mechanism are arranged side by side on the inner side of the short rib buffer chain and the long rib buffer chain 21. The bracket mechanism 3 includes multiple bracket frames 31, which are used to support the positioning net assembled from the long ribs and short ribs. The welding mechanism welds the intersection of the long ribs and short ribs. The welding mechanism includes at least one welding machine 8. In this embodiment, the welding mechanism includes a ground rail, on which at least one resistance welding machine is slidably arranged.

[0091] A short rib feeding mechanism 9 is provided on the outside of the short rib buffer chain to grab the short ribs and place them on the bracket frame 31.

[0092] A long rib feeding mechanism 4 and a transfer mechanism 5 are provided on the outside of the long rib buffer chain 21. The long rib feeding mechanism 4 is used to grab the long rib and place it on the bracket frame 31.

[0093] A welding station 7 is provided downstream of the bracket mechanism 3, and the welding station 7 is located on one side of the welding mechanism; multiple positioning nets of different sizes are picked up by the transfer mechanism 5 and placed onto the welding station 7, and the welding mechanism welds the multiple positioning nets into a T-beam positioning net.

[0094] A buffer rack 6 is set on the other side of the welding station 7 away from the welding mechanism. The T-beam positioning net is grabbed and temporarily stored in the buffer rack 6 by the transfer mechanism 5.

[0095] In this processing production line, the straightening and cutting machine 1 cuts the steel bars into short bars or long bars of the required length. The cut short bars or long bars enter the bar feeding mechanism 11, which conveys the short bars or long bars downstream. When the short bars are conveyed to the short bar buffer mechanism 10, they enter the short bar buffer mechanism 10 and are temporarily stored on the short bar buffer chain. When the long bars are conveyed to the long bar buffer mechanism 2, they enter the long bar buffer mechanism 2 and are temporarily stored on the long bar buffer chain 21.

[0096] The short rib feeding mechanism 9, located outside the short rib buffer chain, grabs the short ribs and places them on the bracket frame 31 inside the short rib buffer chain. The long rib feeding mechanism 4, located outside the long rib buffer chain 21, grabs the long ribs and places them on the bracket frame 31 inside the long rib buffer chain 21. Then, the welding mechanism arranged in parallel on one side of the bracket mechanism 3 welds the intersection of the short ribs and the long ribs to form positioning nets of different sizes.

[0097] The transfer mechanism 5, located outside the long rib buffer chain 21, picks up multiple positioning nets and places them onto the welding station 7. The welding mechanism then welds the multiple positioning nets into a T-beam positioning net. The transfer mechanism 5 then picks up the T-beam positioning net from the welding station 7 and places it onto the buffer rack 6 for temporary storage. Repeating the above process can achieve continuous production of T-beam positioning nets.

[0098] In summary, the buffer chain in this processing line is located near the bracket frame 31, the feeding mechanism is located near the buffer chain, and the welding mechanism is located near the bracket frame 31 and the welding station 7. This makes the distribution of each mechanism in the processing line reasonable and the connection between each process smooth. This not only makes the layout of the processing line more compact and has a smaller footprint, but also makes the process connection smooth, which greatly improves the production efficiency of the processing line.

[0099] like Figure 2 As shown, the short rib buffer mechanism 10 includes a first slide rail 101 and a second slide rail 102, a first pusher 103 and a second pusher 104, a first short rib buffer chain 107 and a second short rib buffer chain 108; the first slide rail 101 is disposed between the inlet of the first pusher 103 and the rib feeding mechanism 11, and the outlet of the first pusher 103 is provided with the first short rib buffer chain 107; in this embodiment, the first slide rail 101 is perpendicular to the rib feeding mechanism 11, the first pusher 103 is parallel to the first slide rail 101, and the first pusher 103 is perpendicular to the first short rib buffer chain 107.

[0100] In this embodiment, a cylinder can be installed at the position of the feeding mechanism 11 corresponding to the first slide rail 101. The cylinder pushes the short web positioning mesh reinforcing bars on the feeding mechanism 11 onto the first slide rail 101, causing the short web positioning mesh reinforcing bars to slide onto the first pusher 103. After being conveyed by the first pusher 103, the short web positioning mesh reinforcing bars are stored on the first short bar buffer chain 107. Then, the short bar buffer chain moves forward to drive the short bars forward, thereby providing a buffer position for the next short bar. In other embodiments, the short web positioning mesh reinforcing bars on the feeding mechanism 11 can also be placed onto the first slide rail 101 manually, depending on the specific circumstances.

[0101] A short rib dropping platform 109 is provided between the first pusher 103 and the first short rib buffer chain 107. A pusher cylinder 105 is provided on the side of the short rib dropping platform 109 away from the first short rib buffer chain 107, and a short rib centering mechanism 106 is provided on the side of the first short rib buffer chain 107 close to the short rib dropping platform 109. The short rib centering mechanism 106 includes two oppositely arranged push plates, at least one of which is controlled by a cylinder to move. Specifically, when the short rib of the web positioning mesh is conveyed to the position of the short rib dropping platform 109 by the first pusher 103, the pusher cylinder 105 pushes the short rib onto the short rib dropping platform 109, and the short rib falls from the dropping chute of the short rib dropping platform 109 onto the first short rib buffer chain 107 at the bottom of the short rib dropping platform 109. When the short rib reaches the position of the short rib centering mechanism 106, the cylinder drives the pusher plate to move so that the position of the short rib remains consistent.

[0102] The second slide rail 102 is disposed between the inlet of the second pusher 104 and the reinforcing bar feeding mechanism 11, and the outlet of the second pusher 104 is provided with a second short reinforcing bar buffer chain 108. In this embodiment, the second slide rail 102 is perpendicular to the reinforcing bar feeding mechanism 11, the second pusher 104 is parallel to the second slide rail 102, and the second pusher 104 is perpendicular to the second short reinforcing bar buffer chain 108.

[0103] In this embodiment, a cylinder can be installed at the position of the feeding mechanism 11 corresponding to the second slide rail 102. The cylinder pushes the short bottom plate positioning mesh ribs on the feeding mechanism 11 onto the second slide rail 102, causing the short bottom plate positioning mesh ribs to slide onto the second pusher 104. After being conveyed by the second pusher 104, the short bottom plate positioning mesh ribs are stored on the second short rib buffer chain 108. In other embodiments, the short bottom plate positioning mesh ribs on the feeding mechanism 11 can also be placed onto the second slide rail 102 manually, depending on the specific circumstances.

[0104] A short rib dropping platform 109 is provided between the second pusher 104 and the second short rib buffer chain 108. A pusher cylinder 105 is provided on the side of the short rib dropping platform 109 away from the second short rib buffer chain 108, and a short rib centering mechanism 106 is provided on the side of the second short rib buffer chain 108 close to the short rib dropping platform 109. The short rib centering mechanism 106 includes two oppositely arranged push plates, at least one of which is controlled by a cylinder to move. Specifically, when the short rib of the bottom plate positioning net is conveyed to the position of the short rib dropping platform 109 by the second pusher 104, the pusher cylinder 105 pushes the short rib onto the short rib dropping platform 109, and the short rib then falls from the dropping chute of the short rib dropping platform 109 onto the second short rib buffer chain 108 at the bottom of the short rib dropping platform 109. When the short rib reaches the position of the short rib centering mechanism 106, the cylinder drives the pusher plate to move so that the position of the short rib remains consistent.

[0105] In this embodiment, the first slide rail 101 is parallel to the second slide rail 102, the first pusher 103 is parallel to the second pusher 104, and the first short rib buffer chain 107 is parallel to the second short rib buffer chain 108.

[0106] like Figure 3 As shown, the long rib buffer mechanism 2 includes multiple sets of parallel long rib buffer chains 21. A long rib unloading platform 12 is provided inside the long rib buffer chains 21 and the rib feeding mechanism 11. A long rib pushing mechanism 22 is provided at the position of the rib feeding mechanism 11 corresponding to the long rib unloading platform 12. The long rib pushing mechanism 22 is used to push the long ribs onto the long rib unloading platform 12. A long rib centering mechanism 23 is provided outside the rib feeding mechanism 11. The long rib centering mechanism 23 is used to adjust the position of the long ribs.

[0107] In this embodiment, the long rib pushing mechanism 22 includes two cylinders and a push rod. The two cylinders are respectively connected to the two ends of the push rod. The extension direction of the push rod is parallel to the extension direction of the long rib, and the length of the push rod is greater than the length of the long rib, so that the push rod can push the long rib more evenly.

[0108] The long rib centering mechanism 23 includes a baffle, a screw, a motor, and at least one guide rod. One end of the baffle extends above the rib feeding mechanism 11. The motor drives the screw to rotate. The screw is parallel to the rib feeding mechanism 11. The baffle is provided with a threaded hole and at least one guide hole. The screw is threaded into the threaded hole on the baffle. Each guide rod is provided through a guide hole on the baffle. By driving the screw to rotate through the motor, the axial position of the baffle can be adjusted.

[0109] Specifically, the long ribs include web positioning net long ribs and bottom plate positioning net long ribs, and the lengths of the two are different. According to the specific long rib model, the position of the baffle in the long rib centering mechanism 23 is adjusted so that the long ribs of different models can be kept in the middle of the multiple long rib buffer chains 21.

[0110] The feeding mechanism 11 delivers the long bar to the baffle limit position of the long bar centering mechanism 23 and then stops. At this time, the cylinder in the long bar pushing mechanism 22 works, and the push rod drives the long bar to move horizontally, so that the long bar falls from the feeding mechanism 11 onto the long bar dropping platform 12. Then the long bar continues to slide onto the multiple sets of long bar buffer chains 21. The multiple sets of long bar buffer chains 21 move forward synchronously, driving the long bar forward, thereby providing a buffer position for the next long bar.

[0111] All the long rib buffer chains 21 together support the long ribs of the web positioning net, and the two long rib buffer chains 21 located in the middle are used to support the long ribs of the bottom plate positioning net.

[0112] The bracket mechanism 3 includes a track, and multiple bracket frames 31 move along the track. A first adjustment component and a second adjustment component are provided on the bracket frames 31. The first adjustment components on the multiple bracket frames 31 cooperate with each other to support the short and long ribs of the bottom plate positioning net, and the second adjustment components on the multiple bracket frames 31 cooperate with each other to support the short and long ribs of the web plate positioning net.

[0113] In this embodiment, the track includes two parallel slides. The bottom of the bracket frame 31 is provided with multiple sliders, which are guided to move in the two slides respectively, so that the bracket frame 31 can be translated along the track to adjust the position of the bracket frame 31. A slider is provided at each of the four corners of the bottom of the bracket frame 31, and two sliders located on the same side are guided to move in the same slide.

[0114] A rack is provided on the side of one of the slides, and a gear is provided on the bracket frame 31. The gear is driven to rotate by a servo motor. The gear meshes with the rack and drives the transmission. By controlling the rotation of the gear through the servo motor, the bracket frame 31 moves along the track, thereby achieving precise adjustment of the position of the bracket frame 31.

[0115] like Figure 4 As shown, the first pitch adjustment component includes a drive source 32, the telescopic end of the drive source 32 is connected to a first active rack 33, and the extended end of the first active rack 33 is connected to a first bracket 37; in this embodiment, the first bracket 37 is a cross structure, used to support the long ribs and short ribs.

[0116] A first gear 34 is rotatably mounted on the bracket frame 31, and the first gear 34 meshes with the first driving rack 33 for transmission; a first follower rack 35 is also movably mounted on the bracket frame 31, and a follower frame 36 is mounted at one end of the first follower rack 35, and the follower frame 36 is movably mounted on the bracket frame 31.

[0117] In this embodiment, the bracket frame 31 is provided with two guide rails, and the two ends of the follower frame 36 are respectively guided and moved on the two guide rails. The follower frame 36 is perpendicular to the first follower rack 35. When the first adjustment component on the bracket frame 31 needs to support the short and long ribs of the base plate positioning mesh of different sizes, the first active rack 33 is driven to extend or retract by the drive source 32 to adjust the position of the first support 37. At the same time, the first active rack 33 drives the first gear 34 to rotate, and the first gear 34 drives the first follower rack 35 to translate, thereby driving the follower frame 36 to translate, realizing the synchronous adjustment of the positions of the first support 37 and the follower frame 36. This allows the bracket mechanism 3 to support base plate positioning mesh of different sizes, enabling the processing line to produce base plate positioning mesh of different sizes, thus making the processing line more widely applicable.

[0118] like Figure 5 As shown, the second pitch adjustment component includes a drive source 32, and the telescopic end of the drive source 32 is connected to a second active rack 38.

[0119] A second gear 39 is rotatably mounted on the bracket frame 31. The second gear 39 meshes with the second drive rack 38 for transmission. A turntable 310 is mounted on the second gear 39, and multiple arc-shaped elongated holes are provided on the turntable 310.

[0120] The bracket frame 31 is also equipped with a plurality of second supports 311 that are movably guided. The ends of the second supports 311 are provided with guide blocks that move in an arc-shaped elongated hole.

[0121] In this embodiment, a guide rail is provided on the bracket frame 31 for each second bracket 311, so that the second bracket 311 can be guided and moved along the guide rail; wherein, there are four second brackets 311, four guide rails, and four arc-shaped elongated holes on the turntable 310, and the four second brackets 311 are distributed in a cross shape.

[0122] When it is necessary to support the short and long ribs of web positioning mesh of different sizes, the second active rack 38 is extended or retracted by the drive source 32 to drive the second gear 39 to rotate. The second gear 39 synchronously drives the turntable 310 to rotate, and the arc-shaped elongated hole pushes the guide block to move, so that the second bracket 311 is displaced along the guide rail, thereby realizing the adjustment of the position of the second bracket 311. This allows the bracket mechanism 3 to support web positioning mesh of different sizes, enabling the processing production line to produce web positioning mesh of different sizes, and thus making the processing production line more widely applicable.

[0123] In this embodiment, the drive source 32 performs telescopic movement. The drive source 32 can be an electric cylinder, which provides more precise telescopic movement and facilitates accurate control. In other embodiments, the drive source 32 can also be a telescopic rod.

[0128] Two guide rails are provided on the welding frame 71 at both ends of the web plate clamp 73 to allow the web plate clamp 73 to move along the guide rails. The web plate clamp 73 is driven by a set of screw mechanism 13. The web plate clamp 73 is fixedly connected to the nut on the screw.

By driving the lead screw to rotate by the servo motor, the spacing between the short rib magnetic grippers 92 can be adjusted, thereby adjusting the spacing between adjacent short ribs. This allows the short rib gripper to be suitable for processing T-beam positioning nets of different sizes and models.

[0138] like Figure 10 As shown, the long rib gripper 41 includes a long rib rotating platform 413. A long rib frame 411 and a plurality of long rib magnetic grippers 412 are provided at the bottom of the long rib rotating platform 413.

The distance between the two web plate fine-tuning cylinder grippers 516 is adjusted by the extension and retraction movement of the web plate fine-tuning cylinder, so that the web plate gripper assembly can be used for web plate positioning nets of different sizes and models.

[0143] The base plate gripper assembly includes a base plate moving cylinder gripper 515 and a base plate fixing cylinder gripper 513. The base plate fixing cylinder gripper 513 is fixed to the lower surface of the transfer frame 512.

[0144] This application also provides a method for processing a prestressed tendon positioning mesh for highly flexible precast T-beams. The processing method uses the aforementioned production line for processing prestressed tendon positioning mesh for highly flexible precast T-beams, and includes the following steps:

[0145] Step 1: The straightening and cutting machine 1 cuts the steel bars into short bars required for the web positioning mesh and the bottom plate positioning mesh, and then feeds the short bars onto the bar feeding mechanism 11.

[0146] The short reinforcing bars of the web positioning mesh are fed into the first pusher 103 via the first slide 101 by the reinforcing bar feeding mechanism 11, and the short reinforcing bars of the bottom plate positioning mesh are fed into the second pusher 104 via the second slide 102 by the reinforcing bar feeding mechanism.

[0147] Step 2: The first pusher 103 starts and sends the short rib to the first short rib buffer chain 107 for temporary storage, and the second pusher 104 starts and sends the short rib to the second short rib buffer chain 108 for temporary storage.

[0148] At the same time, the straightening and cutting machine 1 successively feeds the long ribs of the web positioning net and the long ribs of the bottom plate positioning net. The rib feeding mechanism 11 conveys the long ribs forward, and the long rib centering mechanism 23 centers the long ribs. Then, the long rib pushing mechanism 22 pushes the long ribs onto the long rib dropping platform 12, and the long ribs slide off the long rib dropping platform 12 onto the long rib buffer chain 21 for temporary storage.

[0149] Step 3: The short rib feeding mechanism 9 first grabs multiple short ribs on the first short rib buffer chain 107 through the short rib gripper, and places the multiple short ribs on multiple second spacing adjustment components on the bracket mechanism 3; In this embodiment, the short rib gripper grabs 11 short ribs at the same time, and the second spacing adjustment components can be adjusted after the short ribs are laid to make the arrangement of short ribs conform to the set spacing.

[0150] Then, the long rib feeding mechanism 4 grabs multiple long ribs on the long rib buffer chain 21 through the long rib gripper 41 and places the multiple long ribs on multiple second adjustment components on the bracket mechanism 3; in this embodiment, the long rib gripper 41 grabs two long ribs, and the two long ribs are distributed in two separate times when feeding, that is, one long rib is placed in a set position first, and then the other long rib is placed in another set position.

[0151] Step 4: Welding machine 8 in the welding mechanism is positioned to weld the intersection of the long and short ribs in step 3 to form the web positioning mesh.

[0152] Meanwhile, the short rib feeding mechanism 9 grabs multiple short ribs on the second short rib buffer chain 108 through the short rib gripper and places the multiple short ribs on multiple first spacing adjustment components on the bracket mechanism 3; in this embodiment, the short rib gripper grabs 8 short ribs at the same time, and the first spacing adjustment components can be adjusted after the short ribs are laid to make the arrangement of short ribs conform to the set spacing.

[0153] The long rib feeding mechanism 4 uses the long rib gripper 41 to grab multiple long ribs on the long rib buffer chain 21 and place them on multiple first adjustment components on the bracket mechanism 3. In this embodiment, the long rib gripper 41 grabs two long ribs in two steps. First, it grabs two long ribs and places them on the two first adjustment components on the left. Then, it grabs two more long ribs, rotates the long rib gripper 41 180°, and places the two long ribs on the two first adjustment components on the right, thereby realizing the fabrication of the two sets of base plate positioning nets.

[0154] Step 5: Welding machine 8 in the welding mechanism is in place and welds the intersection of long and short bars in step 4 to form two sets of bottom plate positioning nets; the transfer mechanism 5 picks up the web plate positioning nets through the transfer gripper 51 and places them on the web plate positioning assembly of the welding table 7; at the same time, the straightening and cutting machine 1 performs the next round of rebar cutting operation, and the rebar feeding mechanism 11 starts the next cycle.

[0155] Step 6: The transfer mechanism 5 picks up the base plate positioning mesh in two separate steps using the transfer gripper 51 and places it on the base plate positioning assembly of the welding station 7. In this embodiment, the transfer mechanism 5 first picks up one piece of base plate positioning mesh and places it on one side of the web plate positioning mesh using the transfer gripper 51, then picks up another piece of base plate positioning mesh, and after rotating it 180°, places the base plate positioning mesh symmetrically on the other side of the web plate positioning mesh.

[0156] Simultaneously, the grasping and placement of short and long reinforcing bars for the web positioning mesh will be carried out in the next round.

[0157] Step 7: The welding machine 8 in the welding mechanism is in place, and the bottom plate positioning mesh and the web plate positioning mesh from step 6 are welded together to form the T-beam positioning mesh.

[0158] Step 8: The transfer gripper 51 in the transfer mechanism 5 picks up the T-beam positioning mesh on the welding table 7 and transfers it to the buffer rack 6 for temporary storage; at the same time, the web positioning mesh is welded, and the short and long ribs of the bottom plate positioning mesh are picked up and placed.

[0159] By repeating the above processing steps, continuous production of T-beam positioning nets can be achieved; at the same time, by adjusting the various components in the processing line, the processing line can produce T-beam positioning nets of different sizes and specifications.

[0160] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
