Description

Technical Field

[0001] The embodiments of the present invention relate to the field of climbing scaffold net production equipment technology, specifically, to a robotic automated production line and production method for climbing scaffold nets. Background Technology

[0002] As a commonly used safety protection facility in construction, the production demand for climbing scaffolding mesh is increasing with the development of the construction industry. In the automated production process of climbing scaffolding mesh, the mesh to be welded usually needs to be positioned using tooling plates to ensure positioning accuracy and stability during the welding process. Therefore, tooling plates are an indispensable key component in the climbing scaffolding mesh production line.

[0003] However, in actual operation, existing climbing scaffolding production lines suffer from efficiency bottlenecks due to the use of tooling plates: to complete the welding of the climbing scaffolding, the tooling plates require frequent reciprocating loading and unloading operations. This involves manual or semi-automatic equipment clamping the climbing scaffolding to be welded onto the tooling plate, removing the finished product from the tooling plate after welding, and then manually moving the tooling plate back to the loading station to await the next clamping. This reciprocating loading and unloading mode not only increases manual intervention and disrupts the production rhythm but also extends the production cycle of a single batch of climbing scaffolding. Furthermore, the frequent handling and positioning adjustments of the tooling plates are prone to errors, potentially affecting subsequent welding accuracy and further hindering the improvement of production efficiency. Summary of the Invention

[0004] To overcome the above-mentioned defects, embodiments of the present invention provide an automated production line and production method for climbing scaffold net robots, which solves the technical problem of low overall production efficiency in existing climbing scaffold net production lines due to the need for reciprocating loading and unloading operations of tooling plates used to fix the climbing scaffold net to be welded.

[0005] According to one aspect, at least one embodiment of the present invention provides an automated production line for welding climbing scaffold nets, the climbing scaffold nets including a plurality of side frame strips, horizontal supports and two diagonal supports, including a roller conveyor line and a first welding robot workstation, a flipping mechanism and a second welding robot workstation arranged sequentially along the roller conveyor line: the first welding robot workstation is used for welding the front side of the climbing scaffold nets, the flipping mechanism is used for the climbing scaffold nets, and the second welding robot workstation is used for welding the back side of the climbing scaffold nets; The roller conveyor line has an upper line and a lower line. Tooling plates for supporting climbing scaffold nets are placed on both the upper and lower lines. The upper line is used to transport the tooling plates and climbing scaffold nets, and the lower line is used to transport the unloaded tooling plates in the opposite direction. The roller conveyor line is provided with a first lifting platform and a second lifting platform at both ends. The first lifting platform is used to lift the tooling plate on the lower line to the upper line, and the second lifting platform is used to lower the tooling plate at the end of the upper line to the lower line.

[0006] For example, in an automated production line and method for a climbing scaffold robot provided in at least one embodiment of the present invention, both the first lifting platform and the second lifting platform include: A first frame is located at the end of the roller conveyor line. A plurality of first conveyor rollers are rotatably connected to the first frame. The plurality of first conveyor rollers can form a first conveying plane at the same height as the lower line body. The first conveying plane is used to receive the tooling plate on the lower line body. A lifting frame is vertically slidably connected to the first frame. A plurality of second conveying rollers are rotatably connected to the lifting frame. The first and second conveying rollers are vertically staggered. The plurality of second conveying rollers can form a second conveying plane at the same height as the upper or lower production line under the drive of the lifting frame. The second conveying plane is used to transfer the tooling plate to the upper or lower production line.

[0007] For example, in an automated production line and method for a climbing scaffold net robot provided in at least one embodiment of the present invention, both the first welding robot workstation and the second welding robot workstation include a second frame and a welding manipulator. The welding manipulator is slidably connected to the second frame and is used to weld several frame strips, horizontal supports and two diagonal supports to form a climbing scaffold net.

[0008] For example, in an automated production line and method for a climbing scaffold robot provided in at least one embodiment of the present invention, the tooling plate includes: plate body; An outer frame is provided on the plate, and the inner sidewall of the outer frame is used to abut against the sidewall of the frame strip to limit the frame strip. The first limiting post is provided on the plate body. Several groups of the first limiting posts are arranged at transverse intervals along the roller conveyor line. Each group has two first limiting posts. The two first limiting posts in the same group are located on both sides of the horizontal support and are used to abut against the side wall of the horizontal support to limit the horizontal support. The limiting components are provided in two sets, which are symmetrically distributed on both sides of the transverse support. Each set of the limiting components includes two limiting units, which are arranged at a distance along the transverse direction of the roller conveyor line and are used to limit the two ends of the inclined support respectively.

[0009] For example, in an automated production line and method for a climbing scaffold robot provided in at least one embodiment of the present invention, the limiting unit includes: Mounting plate, the mounting plate is embedded in the top surface of the plate body, and the mounting plate is provided with a limiting groove arranged along the conveying direction of the roller conveyor line; A limiting slider is slidably disposed in the limiting groove. A second limiting post is provided at the top of the limiting slider. The second limiting post can abut against the side wall of the inclined support under the sliding motion of the limiting slider. A ratchet roller is rotatably embedded in the mounting plate and located at one end of the limiting slide groove. A traction line connected to the limiting slider is wound around the ratchet roller, and the ratchet roller can pull the limiting slider to slide through the traction line. A limiting pawl is rotatably embedded in the mounting plate and is used to engage with the ratchet roller to limit the reverse rotation of the ratchet roller.

[0010] For example, in an automated production line and method for a climbing scaffold robot provided in at least one embodiment of the present invention, the limiting pawl has an abutting inclined surface, the height of which gradually increases from one side of the limiting pawl to the other side, and the limiting unit further includes: The take-up roller is rotatably embedded in the mounting plate and located at the other end of the limiting slide groove. The take-up roller and the limiting slider are connected by a reset line. A spring is sleeved on the rotating shaft of the take-up roller. The pressing rod slides through the mounting plate in the vertical direction. The top of the pressing rod is provided with a pressing part. An elastic element is sleeved on the pressing rod. The elastic element is located between the pressing part and the mounting plate. The elastic element is used to elastically push the pressing part upward. The pressing rod can be moved down to abut against the abutting inclined surface to drive the limiting pawl to rotate and separate from the ratchet roller.

[0011] For example, in an automated production line and production method for a climbing frame robot provided in at least one embodiment of the present invention, a first receiving groove for installing the first limiting post is provided on the plate body. The first receiving groove is arranged laterally along the roller conveyor line. The first limiting post is oscillatingly connected to the first receiving groove. The first limiting post can be oscillating vertically to retract into the first receiving groove. The limiting slider has a second receiving groove for installing the second limiting post. The second limiting post is oscillatingly connected to the second receiving groove and can oscillate vertically to retract into the second receiving groove.

[0012] For example, in an automated production line and production method for a climbing scaffold robot provided in at least one embodiment of the present invention, the outer frame is provided with a plurality of positioning holes, and the plate is provided with a plurality of positioning posts that correspond one-to-one with the positioning holes.

[0013] For example, in an automated production line and method for a climbing scaffold robot provided in at least one embodiment of the present invention, the side wall of the plate is provided with an insertion hole, and the flipping mechanism includes: A tilting frame, which is mounted across the roller conveyor line; A rotating disk is movably and rotatably connected to the tilting frame, and the rotating shaft of the rotating disk is arranged along the conveying direction of the roller conveyor line. The mounting components are of two kinds, and the two mounting components are slidably connected to the rotating disk radially, and the two mounting components can move closer to or further away from each other; The insertion rod is provided in two sets, and the two sets of insertion rods are slidably connected to the two mounting parts respectively. The insertion rod can be slidably inserted into the insertion hole. The pre-installed plate is used to engage with a set of insert rods located on the upper layer and to fasten to the tooling plate so that the tooling plate can rotate the climbing scaffold net under the drive of the rotating disk. The pre-installed plate can form the plate body located below the climbing scaffold net after the climbing scaffold net is rotated, and the plate body can form the pre-installed plate located above the climbing scaffold net after the climbing scaffold net is rotated.

[0014] A method for producing climbing scaffold netting, using an automated production line with a climbing scaffold netting robot, includes the following steps: S1. Workpiece clamping: Place several edge strips, horizontal supports and two diagonal supports into the tooling plate, and rotate the ratchet roller to complete the clamping. S2, Top surface welding: The climbing scaffold mesh is transported to the first welding robot workstation using a roller conveyor line so that the top surface of the climbing scaffold mesh can be welded by the first welding robot workstation; S3. Flipping Operation: The flipping mechanism has a non-flipping state and a flipping state. When the flipping mechanism is in the non-flipping state, the upper set of insertion rods is inserted into the pre-installed plate, and the lower set of insertion rods retracts. When the flipping mechanism is in the flipping state, the two sets of insertion rods are inserted into the pre-installed plate and the plate body respectively. When the flipping mechanism is in the non-flipping state, the roller conveyor line transports the climbing frame net and the tooling plate to the flipping mechanism. The rotating disk moves and drives the pre-installed plate to fasten onto the tooling plate. At this time, it enters the flipping state, flipping the tooling plate, climbing frame net and pre-installed plate. After flipping, it enters the non-flipping state, and the lower insertion rod retracts and separates from the pre-installed plate that forms the plate body. S4. Backside welding: The tooling plate is transported to the second welding robot workstation to complete the welding on the other side; S5. Circulating feeding: The second lifting platform moves the tooling plate down, and the unloaded tooling plate enters the lower line for circulation.

[0015] The beneficial effects of the embodiments of the present invention are as follows: In this invention, the upper and lower roller conveyor lines work together to form a circulating conveying channel for the tooling plates. This allows the tooling plates to return from the end of the production line to the beginning without manual handling, reducing manual intervention and avoiding production interruptions. This is thanks to the reverse conveying design of the upper and lower lines, which enables automatic circulation of the tooling plates and shortens the production cycle of a single batch of climbing frame mesh. The first and second lifting platforms enable automatic switching of the tooling plates between the upper and lower lines, eliminating the need for manual handling and reducing positioning errors during tooling plate handling. This ensures positioning accuracy during subsequent welding because the lifting platforms can precisely align with the upper and lower lines, ensuring the tooling plates remain in a stable position during the switching process. The first welding robot workstation, the flipping mechanism, and the second welding robot workstation are arranged sequentially along the roller conveyor line, enabling the climbing scaffold mesh to complete continuous front welding, flipping, and back welding operations on the same conveyor line. Combined with the cyclical conveying of the tooling plates, a complete automated production process is formed. The close connection between the various mechanisms further improves production efficiency. This is because the workstations are arranged sequentially along the conveyor line and match the conveying rhythm of the tooling plates, realizing the continuous and automated welding of the climbing scaffold mesh.

[0024] like Figures 1-12The diagram illustrates an automated robotic production line for a climbing scaffold net according to an embodiment of the present invention. The climbing scaffold net used for production includes several frame strips 11, horizontal supports 12, and two diagonal supports 13. The automated robotic production line includes a roller conveyor line 2 and a first welding robot workstation 4, a flipping mechanism 5, and a second welding robot workstation 6 arranged sequentially along the roller conveyor line 2. The roller conveyor line 2 has an upper line body 21 and a lower line body 22, both of which have tooling plates 8 placed on them. The tooling plates 8 are used to support the climbing scaffold net 1. The first welding robot workstation 4 is located on one side of the roller conveyor line 2 and is used to perform welding operations on the front side of the climbing scaffold net 1 supported by the tooling plate 8 on the upper line body 21. The flipping mechanism 5 spans across the roller conveyor line 2 and is used to flip the climbing scaffold net 1 after welding by the first welding robot workstation 4. The second welding robot workstation 6 is located on the roller conveyor line 2 at a subsequent position corresponding to the flipping mechanism 5 and is used to perform welding operations on the back side of the flipped climbing scaffold net 1. The roller conveyor line 2 is provided with a first lifting platform 3 and a second lifting platform 7 at both ends. The first lifting platform 3 is located at the starting end of the roller conveyor line 2 and can connect with the lower line body 22 and the upper line body 21 to lift the empty tooling plate 8 on the lower line body 22 to the upper line body 21. The second lifting platform 7 is located at the end of the roller conveyor line 2 and can connect with the upper line body 21 and the lower line body 22 to lower the empty tooling plate 8 after the work is completed at the end of the upper line body 21 to the lower line body 22.

[0025] By setting up a circulating conveying path for the tooling plate 8 through two layers of conveyor lines, and cooperating with the lifting platforms at both ends, the tooling plate 8 can be transferred between the upper and lower layers of conveyor lines 22. At the same time, welding and flipping mechanisms 5 are set up sequentially along the conveying path to realize continuous welding operations of the climbing frame mesh 1.

[0026] Its workflow is as follows: In the initial state, the unloaded tooling plate 8 is located on the lower line 22. The first lifting platform 3 lifts the tooling plate 8 on the lower line 22 to the upper line 21. Under the conveying action of the upper line 21, the tooling plate 8 moves to the clamping station, clamps the climbing scaffold mesh 1 to be welded, and is then conveyed to the first welding robot workstation 4 along with the upper line 21 to complete the welding of the front side of the climbing scaffold mesh 1. Afterwards, the tooling plate 8 carries the climbing scaffold mesh 1 to the flipping mechanism 5, which then... The climbing frame mesh 1 is flipped over; after flipping, the tooling plate 8 continues to be transported with the upper line 21 to the second welding robot workstation 6 to complete the welding of the back of the climbing frame mesh 1; after welding, the tooling plate 8 carries the finished climbing frame mesh 1 to the end of the roller conveyor line 2, the finished climbing frame mesh 1 is removed, and the empty tooling plate 8 is lowered to the lower line 22 through the second lifting platform 7. The lower line 22 transports the empty tooling plate 8 in the opposite direction to the first lifting platform 3, waiting for the next cycle.

[0027] The advantage lies in the fact that the upper conveyor 21 and lower conveyor 22 of the roller conveyor line 2 cooperate to form a circulating conveying channel for the tooling plate 8. This allows the tooling plate 8 to return from the end of the production line to the beginning without manual handling, reducing manual intervention and avoiding interruptions in the production rhythm. This is thanks to the reverse conveying design of the upper and lower conveyor lines 22, which realizes the automatic circulation of the tooling plate 8 and shortens the production cycle of a single batch of climbing frame mesh 1. The setting of the first lifting platform 3 and the second lifting platform 7 realizes the automatic conversion of the tooling plate 8 between the upper conveyor line 21 and the lower conveyor line 22. There is no need for manual handling of the tooling plate 8, reducing the positioning error caused during the handling of the tooling plate 8 and ensuring the positioning accuracy during subsequent welding. This is because the lifting platform can accurately connect with the upper and lower conveyor lines 22, ensuring the stability of the tooling plate 8 during the conversion process. The first welding robot workstation 4, the flipping mechanism 5, and the second welding robot workstation 6 are arranged sequentially along the roller conveyor line 2, enabling the climbing scaffold mesh 1 to complete continuous front welding, flipping, and back welding operations on the same conveyor line. Combined with the cyclic conveying of the tooling plate 8, a complete automated production process is formed. The close connection between the various mechanisms further improves production efficiency. This is because the workstations are arranged sequentially along the conveyor line and match the conveying rhythm of the tooling plate 8, realizing the continuous and automated welding of the climbing scaffold mesh 1.

[0028] Furthermore, baffles are provided on both sides of the roller conveyor line 2, and the baffles at the ends of adjacent roller conveyor lines 2 have outwardly expanding guide sections, which can limit the tooling plate 8 during conveying. Meanwhile, a positioning cylinder is installed below the roller conveyor line 2 below the flipping mechanism 5. The piston rod of the positioning cylinder is vertically arranged, and a limit baffle is fixedly connected to its top. When the tooling plate 8 is conveyed to the preset station of the flipping mechanism 5, the position of the tooling plate 8 is detected by a distance sensor, and the positioning cylinder is triggered by the control system. The piston rod of the positioning cylinder drives the limit baffle to extend from bottom to top out of the gap between the conveying rollers of the roller conveyor line 2 until the top surface of the limit baffle is higher than the surface of the conveying roller. At this time, the tooling plate 8 continues to move under the driving force of the roller conveyor line 2. Its front end abuts against the side of the limit baffle and then stops moving, realizing the precise positioning of the tooling plate 8 along the conveying direction. The position of the limit baffle can be preset by the cylinder stroke to ensure that the insertion hole 813 of the tooling plate 8 is aligned with the axis of the insertion rod 56 of the flipping mechanism 5. After positioning is completed, the piston rod of the positioning cylinder retracts, and the limit baffle sinks below the conveying roller, without affecting the subsequent flipping and conveying of the tooling plate 8.

[0029] In some examples, both the first lifting platform 3 and the second lifting platform 7 include a first frame 31, a first conveyor roller 311, a lifting frame 32, and a second conveyor roller 321. For example, as... Figures 2-3As shown, the first frame 31 is located at the end of the roller conveyor line 2. Several first conveyor rollers 311 are rotatably connected to the first frame 31, with their axes distributed laterally along the roller conveyor line 2, forming a first conveying plane at the same height as the lower conveyor line 22. The lifting frame 32 is vertically slidably connected to the inside of the first frame 31 via a guide rail slider structure. Several second conveyor rollers 321 are rotatably connected to the lifting frame 32, with their axes parallel to the first conveyor rollers 311 and vertically staggered, forming a second conveying plane at the same height as the upper conveyor line 21 or the lower conveyor line 22.

[0030] Specifically, the vertical sliding of the lifting frame 32 changes the height of the second conveying plane, enabling the transfer of the tooling plate 8 between the upper and lower line bodies 22. The staggered distribution of the first conveying roller 311 and the second conveying roller 321 avoids structural interference during the lifting process. The workflow is as follows: when the empty tooling plate 8 of the lower line body 22 is conveyed to the first lifting platform 3, the first conveying roller 311 receives the tooling plate 8; the lifting frame 32 rises so that the second conveying plane is at the same height as the upper line body 21, and the second conveying roller 321 moves the tooling plate 8 to the upper line body 21; then the lifting frame 32 descends to reset, and the second conveying plane falls back to the same height as the lower line body 22. The second lifting platform 7 operates in the opposite way. After receiving the empty tooling plate 8 from the upper line body 21, the lifting frame 32 descends so that the second conveying plane is at the same height as the lower line body 22, and the first conveying roller 311 moves the tooling plate 8 to the lower line body 22.

[0031] The advantages are that the conveying planes formed by the first conveyor roller 311 and the second conveyor roller 321 precisely align with the upper and lower layers of the conveyor line 22, respectively. Combined with the stable sliding of the lifting frame 32, this achieves seamless transfer of the tooling plate 8, avoiding positioning deviations caused by manual handling and ensuring the accuracy and stability of subsequent welding processes. The staggered roller structure prevents interference between lifting and conveying actions, improving the operating efficiency of the lifting platform. Combined with the continuous conveying rhythm of the roller conveyor line 2, it shortens the cycle time of the tooling plate 8. The sliding connection structure between the lifting frame 32 and the first frame 31 ensures a smooth lifting process, reducing vibration of the tooling plate 8 during transfer, minimizing structural damage caused by impact, and extending the equipment's service life.

[0032] refer to Figure 1 In some embodiments, both the first welding robot workstation 4 and the second welding robot workstation 6 include a second frame 41 and a welding robot arm 42. The second frame 41 is mounted above the roller conveyor line 2, and its top is provided with a slide rail extending laterally along the roller conveyor line 2. The welding robot arm 42 is slidably connected to the slide rail via a slider, and the end of the robot arm is equipped with a welding gun, which can move along the slide rail under the drive of the control system and complete multi-dimensional welding actions.

[0033] Specifically, the welding robot 42 is used to cover the entire cross-section of the climbing scaffold mesh 1 by sliding, and the precise stopping of the roller conveyor line 2 is used to complete the welding of weld points at different locations. The workflow is as follows: the tooling plate 8 carries the climbing scaffold mesh 1 to be welded to the workstation, and the roller conveyor line 2 stops running; the welding robot 42 moves along the slide rail to the position to be welded and welds the connection points of the frame strip 11 with the horizontal support 12 and the diagonal support 13; after completing the front or back welding, the robot returns to its original position, and the roller conveyor line 2 continues to transport the tooling plate 8 to the next process.

[0034] The advantages are that the sliding structure of the welding robot 42 along the guide rail expands the welding operation range, adapting to the welding needs of climbing scaffold nets 1 of different sizes and specifications, and improving the versatility of the production line. The multi-dimensional movements of the robot, combined with precise sliding positioning, ensure the welding accuracy of each weld point, reducing the problems of missed welds and incomplete welds caused by manual welding. The coordinated control of the workstation and the roller conveyor line 2 ensures seamless connection between the welding process and the conveying rhythm, avoiding waiting time between processes and further improving overall production efficiency.

[0035] Furthermore, the tooling plate 8 includes a plate body 81, an outer frame 82, a first limiting post 83, and a limiting assembly. For example, as... Figures 5-6 As shown, the outer frame 82 is fixed to the top edge of the plate 81, and its inner sidewall is adapted to the sidewall of the frame strip 11. First limiting posts 83 are located on the top surface of the plate 81, with multiple sets spaced laterally along the roller conveyor line 2. Each set has two first limiting posts 83 located on both sides of the horizontal support 12, with their spacing adapted to the width of the horizontal support 12. Two sets of limiting components are provided and symmetrically distributed on both sides of the horizontal support 12. Each set contains two limiting units 84, spaced laterally, corresponding to the two ends of the inclined support 13.

[0036] Specifically, the precise fixing of each component of the climbing scaffold mesh 1 is achieved through the partitioned positioning of the outer frame 82, the first limiting post 83, and the limiting components, avoiding dimensional deviations caused by workpiece displacement during welding. The workflow is as follows: the frame strip 11 is placed against the inner wall of the outer frame 82, the horizontal support 12 is placed between the two sets of first limiting posts 83, and the two ends of the diagonal support 13 are placed into the limiting unit 84 respectively. Each component maintains its positioning state under its own gravity and the action of the limiting structure, and enters the welding process with the tooling plate 8.

[0037] The advantage lies in the clear division of labor among the multiple limiting structures. The outer frame 82 defines the circumferential position of the side frame strip 11, the first limiting post 83 fixes the lateral position of the horizontal support 12, and the limiting components lock the tilt angle of the diagonal support 13, together forming a three-dimensional positioning system. This ensures the precise relative position of each component of the climbing scaffold mesh 1, improving the dimensional consistency of the welded product. Each limiting structure is adapted to the structural features of the climbing scaffold mesh 1 components, achieving stable positioning without additional fastening devices, simplifying the clamping process, and shortening workpiece preparation time.

[0038] Furthermore, the limiting unit 84 includes a mounting plate 841, a limiting slider 842, a second limiting post 843, a ratchet roller 844, and a limiting pawl 845. For example, as Figures 5-10 , Figure 12 As shown, a mounting plate 841 is fitted onto the top surface of a plate body 81, and a limiting groove 8411 is formed on it along the direction of the roller conveyor line 2. A limiting slider 842 is slidably fitted into the limiting groove 8411, and a second limiting post 843 is perpendicular to the top of the slider. A ratchet roller 844 is rotatably fitted into the mounting plate 841 and located at one end of the limiting groove 8411, and a traction line wound around its surface is connected to the end of the limiting slider 842. A limiting pawl 845 is rotatably fitted into the mounting plate 841, and its rotating end is provided with a torsion spring, the end of which can mesh with the teeth of the ratchet roller 844.

[0039] Specifically, the rotation of the ratchet roller 844 pulls the limiting slider 842 to move, and the one-way engagement of the limiting pawl 845 with the ratchet locks the slider position, adjusting the contact force between the second limiting post 843 and the inclined support 13. The working process is as follows: rotating the ratchet roller 844 winds up the traction line, causing the limiting slider 842 to slide along the groove, so that the second limiting post 843 presses against the side wall of the inclined support 13; the limiting pawl 845, under the elastic force of the torsion spring, engages with the ratchet tooth groove, preventing the roller from reversing; when it needs to be released, the limiting pawl 845 is moved to disengage from the ratchet, and the slider resets under the action of external pulling force.

[0040] The advantages are that the ratchet and pawl mechanism allows for the positioning and adjustment of the second limiting post 843. The traction cable drive and slide guide ensure smooth movement of the limiting slider 842, resulting in uniform contact force between the second limiting post 843 and the inclined support 13, preventing workpiece deformation caused by excessive localized force. The pawl's one-way locking function prevents slider displacement due to vibration during welding, ensuring the positioning stability of the inclined support 13 and improving welding quality.

[0041] Furthermore, the abutment ramp 8451 of the limiting pawl 845 gradually increases in height from one side to the other. For example, as... Figures 5-10 As shown, the take-up roller 846 is rotatably embedded in the mounting plate 841 and located at the other end of the limiting slide groove 8411. It is connected to the limiting slider 842 through a reset line. A spring is sleeved on the rotating shaft of the take-up roller 846. The pressing rod 847 slides vertically through the top of the mounting plate 841. The top of the pressing rod is provided with a pressing part 8471, and the rod body is sleeved with an elastic element. The two ends of the elastic element abut against the pressing part 8471 and the top surface of the mounting plate 841, respectively. The bottom end of the pressing rod 847 can contact the abutting inclined surface 8451.

[0042] Specifically, the contact transmission between the pressing rod 847 and the abutting inclined surface 8451 enables the automatic disengagement of the limiting pawl 845, and the energy storage effect of the spring completes the reset of the limiting slider 842. The working process is as follows: pressing the pressing part 8471 causes the pressing rod 847 to move downward, and its bottom end slides along the abutting inclined surface 8451, pushing the limiting pawl 845 to rotate and disengage from the ratchet roller 844; the spring releases potential energy to drive the take-up roller 846 to rotate, and pulls the limiting slider 842 back to its original position through the reset line; after releasing the pressing part 8471, the elastic element pushes the pressing rod 847 upward to reset, and the limiting pawl 845 re-engages with the ratchet under its own gravity.

[0043] The advantages are that the press-type unlocking structure simplifies the operation of the limit unit 84, eliminating the need for manual ratchet operation, shortening workpiece disassembly time, and improving loading and unloading efficiency. The cooperation between the spring and the take-up roller 846 enables the automatic reset of the limit slider 842, reducing manual intervention and lowering operational intensity. The elastic element ensures that the press rod 847 automatically resets, keeping the limit ratchet 845 engaged with the ratchet at all times, ensuring the reliability of the locked state.

[0044] Furthermore, such as Figures 5-10 As shown, a first receiving groove 811 extending laterally is provided on the plate 81. A first limiting post 83 is oscillatingly connected to the first receiving groove 811 via a pin and can oscillate vertically around the pin until it is closed within the groove. A second receiving groove 8421 is provided on the top surface of the limiting slider 842. A second limiting post 843 is oscillatingly connected to the groove via a pin and can oscillate vertically around the pin until it is closed within the groove.

[0045] Specifically, the space occupied in the non-working state is reduced by swinging and retracting the limiting posts, thus avoiding interference with other structures. The workflow is as follows: when clamping the workpiece, the first limiting post 83 and the second limiting post 843 are rotated out of the receiving groove to a vertical position; after welding is completed, the limiting posts are swung and retracted into the groove to keep the top surface of the tooling plate 8 flat.

[0046] The advantages are that the retracted limiting posts make the top surface of the tooling plate 8 flat, facilitating the transport and stacking of empty tooling plates 8 and improving space utilization. The first receiving groove 811 and the second receiving groove 8421 protect the first limiting post 83 and the second limiting post 843 from structural damage caused by collisions during transport, extending the service life of the limiting posts. The swing-type structure is easy to operate, and the state can be changed without disassembly, adapting to the rapid changeover requirements of the production line.

[0047] Furthermore, such as Figures 5-10 As shown, the top surface of the outer frame 82 has positioning holes 821 on all four sides, and the top surface of the plate 81 has a corresponding upward protruding positioning post 812. The diameter of the positioning post 812 is adapted to the diameter of the positioning hole 821, and its height is greater than the thickness of the outer frame 82.

[0048] Specifically, the positioning of the outer frame 82 on the plate 81 is achieved through the insertion and engagement of the positioning post 812 and the positioning hole 821, ensuring the relative stability of the inner wall of the outer frame 82 and the edge strip 11. The workflow is as follows: when installing the outer frame 82, align the positioning hole 821 with the positioning post 812 and insert it until the bottom surface of the outer frame 82 is in contact with the top surface of the plate 81, thus completing the rapid positioning of the outer frame 82.

[0049] The advantages are that the mating structure of the positioning post 812 and the positioning hole 821 simplifies the installation process of the outer frame 82, ensuring installation position accuracy without additional measurement and shortening equipment debugging time. The rigid connection formed by the plug-in mating enhances the overall stability of the outer frame 82 and the plate 81, avoiding displacement of the outer frame 82 caused by welding vibration and ensuring the positioning accuracy of the frame strip 11. The height of the positioning post 812 is greater than the thickness of the outer frame 82, which can form a gap when multiple tooling plates 8 are stacked, preventing the outer frames 82 from being damaged by mutual squeezing.

[0050] Furthermore, such as Figures 4-11 As shown, the flipping mechanism 5 includes a flipping frame 51, a rotating disk 54, mounting components 55, insertion rods 56, and a pre-installed plate 57. The flipping frame 51 spans the roller conveyor line 2, and its top is provided with guide rails that run vertically and horizontally along the roller conveyor line 2. The rotating disk 54 is connected to the guide rails via a slider, and can move along the guide rails and rotate around its own axis, with the rotation axis set along the conveying direction of the roller conveyor line 2. Two mounting components 55 are connected radially along the rotating disk 54 via slide rails, and can slide radially to move closer or further apart under the action of a driving component. Each set of insertion rods 56 is slidably connected to the mounting component 55 via a sliding sleeve, and its axis is parallel to the horizontal direction of the roller conveyor line 2, allowing it to extend and retract along the axial direction. The insertion holes 813 on the side wall of the plate 81 are adapted to the insertion rods 56, and the edge of the pre-installed plate 57 is provided with holes adapted to the upper insertion rods 56, and the positioning posts 812 on the plate 81 correspond to the positioning grooves on the pre-installed plate 57.

[0051] The extension and retraction of the insertion rod 56 is achieved by a pneumatic drive device (such as a cylinder) mounted on the mounting component 55. Specifically, the mounting component 55 has a cylinder with its protruding end facing away from the extension direction of the insertion rod 56. The piston rod of the cylinder is fixedly connected to the insertion rod 56, and the air inlet and outlet of the cylinder are connected to an air source and a solenoid valve via air pipes. When the control system issues an extension / retraction command, the solenoid valve switches the air path direction. When insertion is required, the cylinder is vented to drive the piston rod to retract, which in turn causes the insertion rod 56 to slide along the sliding sleeve and be inserted into the insertion hole 813 of the plate 81 or the corresponding hole of the pre-mounted plate 57. When retraction is required, the cylinder reverses airflow to drive the piston rod to extend, causing the insertion rod 56 to disengage from the insertion hole, thus separating it from the plate or pre-installed plate.

[0052] Specifically, the spacing of the insertion rods 56 is adjusted by the radial movement of the mounting piece 55 to adapt to different sizes of tooling plates 8. The tooling plate 8 and the pre-installed plate 57 are fixed by the insertion of the insertion rods 56 and the insertion holes 813. Combined with the rotation of the rotating disk 54, the climbing frame net 1 is flipped. The fastening of the pre-installed plate 57 and the tooling plate 8 makes them abut against each other's pressing rods 847, so as to trigger the pressing rods 847 to reset the limit slider 842. The workflow is as follows: In the initial state, the insertion rod 56 of the upper mounting component 55 is inserted into the pre-installed plate 57, and the insertion rod 56 of the lower mounting component 55 actively retracts (non-flipping state); when the tooling plate 8 is conveyed to the underside of the flipping mechanism 5, the rotating disk 54 moves down to make the pre-installed plate 57 fasten onto the tooling plate 8, and the positioning pin 812 is inserted into the positioning slot. At this time, the distance between the pre-installed plate 57 and the plate body 81 triggers the pressing rod 847, causing the limit slider 842 to reset; the insertion rod 56 of the lower mounting component 55 actively extends out and inserts into the insertion hole 813 of the plate body 81, and the mounting component 55 moves radially to clamp (flipping state); the rotating disk 54 rotates 180 degrees to complete the flipping, and the lower (formerly upper) insertion rod 56 actively retracts and disengages from the original pre-installed plate 57 (now plate body 81), and the upper (formerly lower) insertion rod 56 drives the original plate body 81 (now pre-installed plate 57) to reset; the flipping mechanism 5 resets to the non-flipping state, and the tooling plate 8 moves to the next process with the conveyor line.

[0053] The advantages are that the radial sliding of the mounting part 55 and the telescopic cooperation of the insertion rod 56 allow the flipping mechanism 5 to adapt to tooling plates 8 of different specifications, improving the equipment's versatility. The insertion of the insertion rod 56 into the insertion hole 813, combined with the guidance of the positioning post 812 and the positioning groove, ensures that the relative positions of the tooling plate 8, the climbing frame net 1, and the pre-installed plate 57 are fixed during the flipping process, preventing workpiece displacement and ensuring welding accuracy. When the fastening is activated, the pressing rod 847 automatically resets the limit slider 842, eliminating manual operation steps, shortening the flipping preparation time, and improving efficiency. The movement and rotation of the rotating disk 54 are linked, realizing the automated and continuous flipping action, reducing manual intervention and labor intensity.

[0054] A method for producing climbing scaffold netting, using an automated production line with a climbing scaffold netting robot, includes the following steps: S1. Workpiece clamping: Place the frame strip 11, horizontal support 12 and diagonal support 13 into the tooling plate 8. The frame strip 11 is attached to the inner side wall of the outer frame 82. The horizontal support 12 is placed between the first limiting posts 83. Rotate the ratchet roller 844 to make the second limiting post 843 press against the diagonal support 13 to complete the clamping.

[0055] S2, Top surface welding: Roller conveyor line 2 transports tooling plate 8 to the first welding robot workstation 4, where the welding robot welds the front welding points of the climbing frame mesh 1.

[0056] S3. Flipping Operation: The flipping mechanism 5 is initially in a non-flipping state. The upper insertion rod 56 is connected to the pre-installed plate 57, and the lower insertion rod 56 retracts. After the tooling plate 8 is in place, the rotating disk 54 moves down to make the pre-installed plate 57 fasten onto the tooling plate 8. The positioning post 812 enters the positioning groove, triggering the pressing rod 847 to reset the limit slider 842. The lower insertion rod 56 extends out of the insertion hole 813 of the insertion plate body 81, and the mounting part 55 is clamped and enters the flipping state. The rotating disk 54 rotates 180 degrees. After flipping, the lower insertion rod 56 retracts and disengages from the plate body 81 (the original pre-installed plate 57), entering a non-flipping state. The rotating disk 54 rises to separate the upper plate body 81 (the current pre-installed plate 57) from the outer frame 82.

[0057] S4. Backside welding: Tooling plate 8 is conveyed by roller conveyor line 2 to the second welding robot workstation 6 to complete backside welding.

[0058] S5. Circular feeding: After the finished product is removed, the empty tooling plate 8 is lowered to the lower line body 22 via the second lifting platform 7, and then conveyed in the opposite direction to the first lifting platform 3 to enter the next cycle.

[0059] Specifically, based on the structural characteristics of the production line, each process is connected in series according to the conveying sequence. The state switching of the flipping mechanism 5 connects the positive and negative welding, and continuous production is achieved through the cyclic conveying of the tooling plate 8. The workflow revolves around the upper and lower layers of the roller conveyor line 2, so that the clamping, welding, flipping and other steps form a closed loop, and the actions of each step are linked with the equipment structure.

[0060] The advantages are as follows: S1 utilizes multiple sets of limiting structures on the tooling plate 8 to achieve rapid and precise clamping, ensuring reliable positioning of the climbing frame mesh 1 component; S3 achieves automatic flipping and limit reset through the state transition of the flipping mechanism 5, connecting the positive and negative welding processes and reducing process intervals; S5 relies on the cooperation of the upper and lower line bodies 22 and the lifting platform to achieve automatic circulation of the tooling plate 8, avoiding manual handling. Each step is closely coordinated with the equipment structure to form a continuous automated production process, significantly shortening the production cycle. The automatic reset of the limit slider 842 during the flipping operation ensures that the entire process can be repeated. The entire method requires no manual intervention in the handling and flipping operation of the tooling plate 8, reducing human error and improving the overall efficiency and stability of the production line.
