Description

Technical Field

[0001] The present invention relates to the field of bead wires, and particularly to a winding and transporting device for automated bead wire production. Background Art

[0002] Bead wire is the core skeleton material of a tire. Its production process mainly includes raw material treatment (high-carbon steel wire rods are pickled, phosphated, drawn, heat-treated, and copper-plated to form high-strength single wires), winding and tying (multiple single wires are wound into a ring-shaped bead and mechanically tied and fixed), receiving and storing (the bead is transferred to the hanging rod of a rotary receiving rack, and each group can store about 12 - 18 beads in 3 batches), and manual transfer (after the receiving rack rotates, workers manually unload, transport, and re-hang it onto the equipment of the next process).

[0003] The existing process has the following defects: 1) The manual unloading, transportation, and hanging processes take about 3 - 5 minutes per batch, resulting in high labor costs and limited production rhythm; 2) Manual operation is prone to cause bead collision and tying loosening, with a defective rate of about 0.8% - 1.2%; 3) The feeding heights of equipment in different processes vary greatly (±150 mm), and manual adjustment has poor adaptability, requiring frequent customization of tooling. Summary of the Invention

[0004] Based on this, it is necessary to provide a winding and transporting device for automated bead wire production in view of the problems of the existing technology, aiming to solve the problems of low efficiency of manual transfer, easy loosening, and poor equipment compatibility of the existing bead wire.

[0005] To solve the problems of the existing technology, the technical solution adopted by the present invention is as follows: A winding and transporting device for automated bead wire production includes a winding and tying machine and a rotary receiving rack arranged beside the winding and tying machine. The rotary receiving rack includes a turntable base, a column arranged on the turntable base, and three groups of hanging rods evenly distributed along the circumferential direction at the upper end of the column. The number of each group of hanging rods is two, and the two are arranged in parallel and adjacent to each other. At the top of the column, there is also a feeding arm for pulling the wire bead deep into the hanging rod and a discharging arm for pushing the wire bead out from the deep part of the hanging rod. It also includes a rotary transporting rack that cooperates with the rotary receiving rack. The rotary transporting rack includes an AGV trolley base, a turntable arranged on the AGV trolley base, a longitudinal beam support column arranged at the top of the AGV trolley base and connected to the output of the turntable, a lifting mechanism arranged inside the longitudinal beam support column, and three groups of receiving mechanisms evenly distributed on the outer side of the upper half of the longitudinal beam support column. The receiving mechanism includes two spiral hanging rods arranged in parallel at intervals and symmetrically distributed, and a driving mechanism for driving the two spiral hanging rods to rotate towards each other. The distance between the spiral hanging rods is greater than the distance between the hanging rods. An inclination mechanism for driving the two spiral hanging rods to tilt at an angle is also arranged on the longitudinal beam support column.

[0006] Furthermore, a optical axis for temporarily storing bead wires is fixedly connected to the free end of each of the spiral hanging rods, and the length of the optical axis is greater than the total thickness of all the bead wires on each set of material hanging rods.

[0007] Furthermore, the driving mechanism includes a first driving motor, two meshing gears, two first belt pulleys coaxially and fixedly connected to the two gears respectively, two second belt pulleys respectively distributed outside the two first belt pulleys, and two synchronous belts respectively connecting the corresponding first belt pulleys and the second belt pulleys.

The difference between the inner radius of the arc-shaped limiting cover and the outer radius of the bead wire is greater than the thickness of one bead wire and less than the thickness of two bead wires. The gap between the spiral outer wall of the spiral hanging rod and the inner wall of the arc-shaped limiting cover is less than the thickness of one bead wire. An inclined corner for intercepting the stacked bead wires is formed at the inner edge of one end of the arc-shaped limiting cover away from the longitudinal beam support column. One end of the arc-shaped limiting cover close to the longitudinal beam support column is fixedly connected through a support seat. The middle of the support seat is fixedly connected to the bottom of the widened motor bracket. Fixing extension plates extending upward for fixing the corresponding ends of the arc-shaped limiting cover are arranged at both ends of the support seat.

[0009] Furthermore, the widened motor bracket is pivotally connected to the lifting output end of the lifting mechanism. The tilting mechanism includes an electric push rod and an L-shaped hanging bracket. The L-shaped hanging bracket is arranged in a vertical state, and its short side faces upward and is fixedly connected to the lifting output end of the lifting mechanism. A hinge seat for pivotally connecting one end of the electric push rod is arranged at the lower end of the L-shaped hanging bracket. A shaft seat for pivotally connecting the other end of the electric push rod is fixedly arranged at the bottom of the support seat. Rollers fitting the outer wall of the longitudinal beam support column are arranged on both sides of the lower end of the L-shaped hanging bracket. A fixed wheel shaft for connecting the rollers on both sides is arranged at the lower end of the L-shaped hanging bracket.

[0010] Furthermore, the lifting mechanism includes a second driving motor fixedly arranged at the top end of the longitudinal beam support column, a long lead screw located on the inner side of the longitudinal beam support column, and a Y-shaped lifting block threadedly matched with the long lead screw, the upper and lower ends of the inner side of the longitudinal beam support column are provided with bearings for connecting the two ends of the long lead screw, the upper half side wall of the longitudinal beam support column is formed with three strip-shaped sliding grooves for the three ends of the Y-shaped lifting block to extend outward, and each outwardly extending end of the Y-shaped lifting block is hinged to the corresponding widened motor bracket.

[0011] Furthermore, a plurality of rollers are arranged on both sides of each end of the Y-shaped lifting block and are fitted to the groove wall of the strip-shaped sliding groove.

[0012] Furthermore, the arc-shaped limit cover is composed of a thin plate sheet metal part, the bevel portion is located at its bent end, and the open side is respectively provided with hollow steel pipes consistent with its generatrix direction at both ends along its arc length, and the hollow steel pipe is welded and fixed to the thin plate sheet metal part, and the upper end of each fixed extension plate is fixedly connected to a positioning column inserted into the corresponding hollow steel pipe.

[0013] Furthermore, a circular baffle is fixedly provided on the outer end of the optical axis to prevent the tire bead wire from falling off the axis, and a fixed sleeve is provided on the end of the spiral hanging rod away from the optical axis to prevent the tire bead wire from escaping from the spiral movement range.

[0014] Furthermore, an annular support seat is fixedly provided at the lower end of the longitudinal beam support column, a circular support platform is fixedly provided on the top of the annular support seat, the lower end of the longitudinal beam support column is fixedly connected to the center of the circular support platform, a steel frame for resisting deformation is fixedly provided at the bottom of the circular support platform, the center of the circular support platform is fixedly connected to the rotating output end of the turntable, and a plurality of universal wheels are evenly distributed along the circumferential direction and roll downwardly in contact with the base of the AGV trolley.

[0015] Compared with the prior art, the present invention has the following beneficial effects: First, the whole process is automated, which greatly reduces labor costs: Under the existing technology, each set of tire rims needs to be unloaded, transported, and hung manually, which takes about 150 seconds and requires 2-3 workers on duty; this solution uses the AGV trolley to automatically connect the material receiving rack with the next process equipment, and uses the spiral hanging rod to rotate to achieve equidistant arrangement of the tire rim wires. No manual intervention is required throughout the process, and the processing time of a single set of tire rims is shortened to within 30 seconds, reducing labor costs by more than 70%; Second, the dynamic anti-loosening design improves product quality: In the prior art, manual unloading easily causes bead collision and chuck loosening, with a defective rate of approximately 0.8% - 1.2%; in this solution, when the spiral hanging rod rotates, the bead position is constrained by the arc-shaped limiting cover, and the pitch of the spiral groove is strictly matched with the bead diameter to ensure neat arrangement. The tilting mechanism raises the optical axis so that the bead smoothly enters the spiral groove under the action of gravity, avoiding deformation caused by mechanical pushing, and reducing the defective rate to less than 0.2%, thereby reducing quality losses; Third, multi-dimensional adaptive adjustment enhances equipment compatibility: In the prior art, manual labor is required to manually adjust the hanging position according to the equipment height, with a narrow adaptation range (±50mm); in this solution, the lifting mechanism drives the Y-shaped lifting block through a long lead screw to achieve a height adjustment of ±200mm for the material receiving mechanism, covering more than 95% of the equipment requirements. The tilting mechanism can adjust the angle of the spiral hanging rod (0° - 15°) to adapt to the unloading postures of different workstations, reducing the cost of tooling customization.

Detailed implementation manners

[0018] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0019] Referring to Figures 1 to 10 As shown, a winding and transporting device for automatic bead wire production includes a coil tying machine and a rotary material receiving rack arranged beside the coil tying machine. The rotary material receiving rack includes a turntable base, a column arranged on the turntable base, and three groups of hanging rods evenly distributed along the circumferential direction at the upper end of the column. The number of each group of hanging rods is two and they are arranged in parallel and adjacent to each other. At the top of the column, there is also a loading arm for pulling the wire coil deep into the hanging rod and an unloading arm for pushing the wire coil out from the deep part of the hanging rod. It also includes a rotary transporting rack cooperating with the rotary material receiving rack. The rotary transporting rack includes an AGV trolley base 1, a turntable 2 arranged on the AGV trolley base 1, a longitudinal beam support column 3 arranged at the top of the AGV trolley base 1 and connected to the output of the turntable 2, a lifting mechanism arranged in the longitudinal beam support column 3, and three groups of material receiving mechanisms evenly distributed on the outer side of the upper half of the longitudinal beam support column 3. The material receiving mechanism includes two spiral hanging rods 4 arranged in parallel at intervals and symmetrically distributed, and a driving mechanism 5 for driving the two spiral hanging rods 4 to rotate towards each other. The distance between the spiral hanging rods 4 is greater than the distance between the hanging rods. The longitudinal beam support column 3 is also provided with a tilting mechanism 6 for driving the two spiral hanging rods 4 to tilt at an angle.

[0020] Working principle: After the bead wire winding and head tying machine completes the bead wire winding and head tying, several bead wires arranged side by side are transferred to the front end of the hanging rod. The loading arm works to move the batch of bead wires hanging at the front end backwards so that the hanging rod can accommodate more batches of bead wires. When a group of hanging rods is full of bead wires, the turntable base drives the column and the hanging rod to rotate 120°, and moves the full hanging rod to the unloading position, waiting for the rotary transport rack to receive the material. This structural design enables the hanging rod to receive and store the bead wires in an orderly manner, and realizes the alternating use of different hanging rod groups through rotation, which improves the efficiency of receiving the material.

[0021] The rotary transport frame includes an AGV trolley base 1, a turntable 2 arranged on the AGV trolley base 1, a longitudinal beam support column 3 arranged on the top of the AGV trolley base 1 and connected to the output of the turntable 2, a lifting mechanism arranged in the longitudinal beam support column 3, and three sets of receiving mechanisms evenly distributed on the outer side of the upper half of the longitudinal beam support column 3. Its working principle is that when the hanging rod of the rotary receiving frame rotates to the unloading position, the AGV trolley base 1 moves to this position through the AGV cruise system, the receiving mechanism receives the tire bead wire unloaded from the hanging rod, and then transmits the tire bead wire one by one backward and evenly distributes it through the rotation of the spiral hanging rod 4. After the three sets of receiving mechanisms are all hung with tire bead wire, the AGV trolley base 1 moves to the loading position of the next process equipment, and the lifting mechanism adjusts the height to match the loading requirements of different equipment, and finally realizes the automatic transfer and transportation of the tire bead wire.

[0022] The free end of each spiral hanging rod 4 is fixedly connected to an optical axis 7 for temporarily storing the tire bead wire. The length of the optical axis 7 is greater than the sum of the thicknesses of all the tire bead wires on each group of hanging rods, ensuring that all the tire bead wires pushed over can be hung within the length range of the optical axis 7.

[0023] Working principle: When the AGV trolley base 1 moves to the unloading position of the rotary receiving rack, the two spiral hanging rods 4 are located below the two hanging rods. The unloading arm pushes out all the tire bead wires on the hanging rods, and the tire bead wires fall on the optical axis 7 below for temporary storage. The tilting mechanism 6 is used to lift the outer end of the spiral hanging rod 4, that is, one end of the optical axis 7, so that all the tire bead wires on the optical axis 7 slide toward the spiral hanging rod 4 to enter the range of spiral conveying. At the same time, the driving mechanism 5 drives the two spiral hanging rods 4 to rotate in opposite directions, and the tire bead wires on the optical axis 7 are transmitted backward one by one through the rotation of the spiral, so that each tire bead wire is finally hung within the spacing of each spiral groove on the two spiral hanging rods 4, so as to achieve uniform distribution of the tire bead wires. The spacing between the spiral hanging rods 4 is greater than the spacing between the hanging rods, so as to avoid collision when receiving the tire bead wires. The tilting mechanism 6 can adjust the angle of the spiral hanging rod 4 according to actual needs to facilitate the sliding and transmission of the tire bead wire.

[0024] AGV is the English abbreviation of Automated Guided Vehicle, which refers to an unmanned automated vehicle with automatic guiding devices such as magnetic strips, tracks or lasers, traveling along a pre-planned path, powered by batteries, and equipped with safety protection and various auxiliary mechanisms (such as loading and unloading, assembly mechanisms).

[0025] Effects and purposes: The design of this feeding mechanism realizes the smooth transfer and uniform distribution of bead wires from the hanging rod to the spiral hanging rod 4, prepares for subsequent transportation and feeding, and improves the stability and efficiency of transportation.

[0026] The driving mechanism 5 includes a first driving motor 8, two meshing gears 9, two first belt pulleys 10 respectively coaxially fixed to the two gears 9, two second belt pulleys 11 respectively distributed outside the two first belt pulleys 10, and two synchronous belts 12 respectively connecting the corresponding first belt pulleys 10 and first belt pulleys 10. The first driving motor 8 is connected to the lifting output end of the lifting mechanism through a widened motor bracket 13. One of the gears 9 is fixed to the output shaft of the first driving motor 8, and the other gear 9 is pivotally connected to one end of the widened motor bracket 13 away from the first driving motor 8. Two L-shaped extension seats 14 are fixed to both sides of the widened motor bracket 13. The two second belt pulleys 11 are respectively pivotally connected to the distal ends of the corresponding L-shaped extension seats 14. One end of each of the two spiral hanging rods 4 is coaxially fixed to the two second belt pulleys 11 respectively.

[0027] Working principle: After the first driving motor 8 is started, it drives the gear 9 fixed to its output shaft to rotate. Since the two gears 9 mesh with each other, the other gear 9 rotates in the opposite direction. The two gears 9 respectively drive the first belt pulleys 10 coaxially fixed to them to rotate. The first belt pulleys 10 drive the second belt pulleys 11 to rotate through the synchronous belts 12, so that the spiral hanging rods 4 coaxially fixed to the second belt pulleys 11 rotate towards each other. The widened motor bracket 13 provides stable support for the driving mechanism 5, and the L-shaped extension seats ensure the installation position and transmission effect of the second belt pulleys 11.

[0028] Effects and purposes: The driving mechanism 5 realizes the rotation of the two spiral hanging rods 4 towards each other through the transmission mode of the gears 9 and belt pulleys, provides power for the transmission of bead wires, and ensures the stability and reliability of the transmission process.

[0029] Above each material receiving mechanism, an arc-shaped limiting cover 15 matching the contour of the bead wire is provided. The difference between the inner radius of the arc-shaped limiting cover 15 and the outer radius of the bead wire is greater than the thickness of one turn of the bead wire and less than the thickness of two turns of the bead wire. The gap between the spiral outer wall of the spiral hanging rod 4 and the inner wall of the arc-shaped limiting cover 15 is less than the thickness of one turn of the bead wire. At the inner edge of the end of the arc-shaped limiting cover 15 away from the longitudinal beam support column 3, an inclined angle part 16 for intercepting the stacked bead wires is formed. One end of the arc-shaped limiting cover 15 close to the longitudinal beam support column 3 is fixedly connected through a support seat 17. The middle of the support seat 17 is fixedly connected to the bottom of the widened motor bracket 13. At both ends of the support seat 17, fixing extension plates 18 extending upward for fixing the corresponding ends of the arc-shaped limiting cover 15 are provided.

[0030] Working principle: During the process of the spiral hanging rod 4 conveying the bead wire, the arc-shaped limiting cover 15 plays a role in restricting the position of the bead wire. Since it matches the contour of the bead wire, and the gap between the spiral outer wall of the spiral hanging rod 4 and the inner wall of the arc-shaped limiting cover 15 is less than the thickness of one turn of the bead wire, it can prevent the bead wire from jumping out of the spiral hanging rod 4 during the conveying process. The inclined angle part 16 intercepts the stacked bead wires and is used to push the accidentally stacked bead wires backward, so that only one bead wire can enter between the arc-shaped limiting cover 15 and the spiral hanging rod 4 at a time, ensuring that the bead wires can be arranged orderly on the spiral hanging rod 4. The support seat 17 and the fixing extension plate 18 fix the arc-shaped limiting cover 15 above the material receiving mechanism and cooperate with the driving mechanism 5 and the spiral hanging rod 4 to jointly complete the conveying and limiting of the bead wire.

[0031] Effects and purposes: The setting of the arc-shaped limiting cover 15 improves the stability and accuracy of the bead wire conveying process, avoids the scattering and chaos of the bead wire, and ensures the smooth progress of subsequent transportation and feeding.

[0032] The widened motor bracket 13 is axially connected to the lifting output end of the lifting mechanism. The tilting mechanism 6 includes an electric push rod 19 and an L-shaped hanging bracket 20. The L-shaped hanging bracket 20 is arranged vertically with its short side facing upward and is fixedly connected to the lifting output end of the lifting mechanism. At the lower end of the L-shaped hanging bracket 20, a hinge seat 21 for axially connecting one end of the electric push rod 19 is provided. At the bottom of the support seat 17, a shaft seat 22 for axially connecting the other end of the electric push rod 19 is fixedly provided. On both sides of the lower end of the L-shaped hanging bracket 20, rollers 23 attached to the outer wall of the longitudinal beam support column 3 are provided. At the lower end of the L-shaped hanging bracket 20, a fixed wheel shaft 24 for connecting the two side rollers 23 is provided.

[0033] Working principle: Angle adjustment mechanism: When it is necessary to introduce the bead wire on the optical axis 7 into the spiral hanging rod 4, the electric push rod 19 starts to perform telescopic movement. Since both ends of the electric push rod 19 are hinged to the L-shaped hanging bracket and the support seat 17 respectively, the telescopic movement of the push rod will generate a lever effect, forcing the widened motor bracket 13 to rotate around its shaft connection fulcrum with the lifting mechanism.

[0034] Lifting the optical axis 7 end: When the push rod shortens, the L-shaped hanging bracket is lifted upward, driving the support seat 17 and the widened motor bracket 13 to rotate, so that one end of the optical axis 7 of the spiral hanging rod 4 is lifted to form an inclined angle.

[0035] Gravity-driven sliding: After the optical axis 7 is inclined, the bead wire temporarily stored on it slides toward the spiral hanging rod 4 under the action of gravity and enters the conveying range of the spiral groove.

[0036] Stability guarantee: The roller 23 at the lower end of the L-shaped hanging bracket always rolls along the outer wall of the longitudinal beam support column 3, offsetting the lateral force generated during the inclination process and ensuring smooth movement without jamming. The fixed wheel shaft 24 enhances the structural rigidity of the L-shaped hanging bracket and avoids deformation.

[0037] Effects and purposes: Automated feeding: The bead wire temporarily stored on the optical axis 7 is automatically introduced into the spiral hanging rod 4 through the tilting mechanism 6 without manual intervention, improving production efficiency.

[0038] Precise positioning: The inclination angle can be accurately controlled by the stroke of the electric push rod 19 to ensure that the bead wire accurately falls into the spiral groove, avoiding jamming or deviation.

[0039] Space optimization: After the optical axis 7 is inclined, the bead wire slides naturally under the action of gravity, reducing mechanical pushing devices, simplifying the structure and reducing energy consumption.

[0040] Supplementary description: When the tilting mechanism 6 is linked with the lifting mechanism, three-dimensional position adjustment of height + angle can be achieved. For example, after the AGV cart moves to the target working station, first match the equipment height through the lifting mechanism, and then accurately push the bead wire onto the equipment hanging rod through the tilting mechanism 6 to further improve the degree of automation.

[0041] The lifting mechanism includes a second driving motor 25 fixedly arranged at the top end of the longitudinal beam support column 3, a long lead screw 26 located inside the longitudinal beam support column 3, and a Y-shaped lifting block 27 threadedly engaged with the long lead screw 26. Bearings 28 for connecting the two ends of the long lead screw 26 are arranged at both the upper and lower ends inside the longitudinal beam support column 3. Three strip-shaped chutes 29 for the three ends of the Y-shaped lifting block 27 to extend outward are formed on the side wall of the upper half of the longitudinal beam support column 3. Each outward extending end of the Y-shaped lifting block 27 is hinged to the corresponding widened motor bracket 13. A plurality of rollers 30 are arranged on both sides of each end of the Y-shaped lifting block 27 and are in contact with the groove wall of the strip-shaped chute 29.

[0042] Working principle: After the second driving motor 25 is started, it drives the long lead screw 26 to rotate. Since the Y-shaped lifting block is threadedly engaged with the long lead screw 26, the rotation of the long lead screw 26 causes the Y-shaped lifting block to move up and down along the long lead screw 26. The three ends of the Y-shaped lifting block extend outward through the strip-shaped chutes 29 and are hinged to the corresponding widened motor brackets 13, thereby driving the material receiving mechanism to move up and down.

[0043] When the Y-shaped lifting block moves up and down in the strip-shaped chute 29, the rollers 30 roll along the groove wall of the strip-shaped chute 29. This rolling method significantly reduces the frictional resistance between the Y-shaped lifting block and the strip-shaped chute 29 compared to direct sliding. On the one hand, it enables the Y-shaped lifting block to move more smoothly in the strip-shaped chute 29, ensuring the smoothness of the lifting process and avoiding jamming caused by excessive friction, thereby ensuring that the material receiving mechanism can accurately reach the specified height position. On the other hand, the evenly distributed rollers 30 can evenly disperse the pressure borne by the Y-shaped lifting block to the groove wall of the strip-shaped chute 29, avoiding wear of the chute caused by excessive local pressure, extending the service life of the strip-shaped chute 29 and the Y-shaped lifting block, and improving the reliability and stability of the entire lifting mechanism.

[0044] Effect and purpose: The lifting mechanism cooperates with the material receiving mechanism and the driving mechanism 5 to adjust the height of the material receiving mechanism according to the feeding height requirements of the next process equipment, realizing the accurate feeding of bead wires. The setting of the rollers 30 further enhances the performance of the lifting mechanism, enabling the device to operate more stably and efficiently, improving the versatility and applicability of the device, and ensuring that the bead wires can be smoothly transferred from the transportation device to the next process equipment.

[0045] The arc-shaped limiting cover 15 is composed of thin sheet metal parts. The beveled corner 16 is located at its bent end. Hollow steel pipes 31 in the same direction as its generatrix are respectively arranged at both ends of the opening side along its arc length. The hollow steel pipes 31 are fixedly welded to the thin sheet metal parts. A positioning column 32 inserted into the corresponding hollow steel pipe 31 is fixedly connected to the upper end of each fixed extension plate 18.

[0046] Working principle: This structural design makes the installation of the arc-shaped limit cover 15 more convenient and stable. The positioning post 32 is inserted into the hollow steel pipe 31, realizing the accurate connection and positioning of the arc-shaped limit cover 15 and the fixed extension plate 18. The thin sheet metal part has a certain flexibility and strength, which can effectively limit the position of the bead wire and reduce the weight of the device at the same time.

[0047] Effects and purposes: This structural design improves the installation efficiency and stability of the arc-shaped limit cover 15, ensures its limiting effect on the bead wire, and further improves the reliability of the bead wire transportation.

[0048] A circular baffle 33 for preventing the bead wire from coming off the shaft is fixedly arranged at the outer end of the optical axis 7, and a limit sleeve 34 for preventing the bead wire from getting out of the spiral moving range is fixedly sleeved at one end of the spiral hanging rod 4 far away from the optical axis 7.

[0049] Working principle: The circular baffle 33 prevents the bead wire from coming off the outer end of the optical axis 7, ensuring the temporary storage safety of the bead wire on the optical axis 7. The limit sleeve 34 prevents the bead wire from getting out of the spiral moving range when moving on the spiral hanging rod 4, ensuring that the bead wire can be accurately arranged and conveyed on the spiral hanging rod 4.

[0050] Effects and purposes: The setting of these two limiting structures improves the safety and stability of the bead wire transportation process, avoids the loss and chaos of the bead wire, and ensures the smooth progress of production.

[0051] Working principle: A circular support seat 35 is fixedly arranged at the lower end of the longitudinal beam support column 3, a circular support platform 36 is fixedly arranged at the top of the circular support seat 35, the lower end of the longitudinal beam support column 3 is fixedly connected to the center of the circular support platform 36, a steel frame 37 for anti-deformation is fixedly arranged at the bottom of the circular support platform 36, the center of the circular support platform 36 is fixedly connected to the rotary output end of the turntable 2, and a plurality of universal wheels 38 which are evenly distributed along the circumferential direction and roll downwardly against the base 1 of the AGV vehicle are arranged at the bottom of the circular support seat 35.

[0052] The circular support seat 35, the circular support platform 36 and the steel frame 37 jointly provide stable support for the longitudinal beam support column 3. The turntable 2 drives the circular support platform 36 and the longitudinal beam support column 3 to rotate, realizing the circumferential movement of the material receiving mechanism and facilitating the docking with different hanging rod groups of the rotary material receiving rack. The universal wheels 38 roll against the base 1 of the AGV vehicle, reducing the frictional resistance during rotation and ensuring the smoothness of rotation.

[0053] Effects and purposes: The support structure improves the stability and rotational flexibility of the longitudinal beam support column 3 and the material receiving mechanism, enabling the device to better complete the tasks of receiving and transporting bead wires.
