Description

Technical Field

[0001] This application relates to the field of automotive parts production logistics and transportation equipment technology, and in particular to an intelligent suspended transportation device for sun visors of new energy vehicles. Background Technology

[0002] Sun visors for new energy vehicles are interior parts, covered with fabric or soft leather, and have high requirements for appearance quality. They must not be squeezed, bumped, or scratched during the production process.

[0003] The existing workshop uses a suspended conveyor line to transport sun visor workpieces. The suspension module is mounted on a circulating traction chain, and the sun visors are transported suspended in the air to avoid stacking and crushing. Currently, conventional suspended conveyor lifting devices require cylinders, solenoid valves, and trailing cables to be installed on the suspension module itself, which move along the track with the chain. When a large number of suspension modules are running simultaneously, the number of trailing cables is large, the wiring is complex, and the repeated bending and aging of the cables leads to a high failure rate and a large maintenance workload. In addition, the existing suspension module's set of actuators can only achieve a single action. To simultaneously achieve two actions—adjusting the sun visor's position and opening the gripper for unloading—two sets of independent cylinders are required, increasing the overall size of the suspension module, the number of parts, and its weight.

[0004] To address these issues, a smart suspension and transportation device for sun visors in new energy vehicles is proposed. Summary of the Invention

[0005] The purpose of this application is to address the technical problems of existing suspended transport devices, such as the large number of trailing cables, high failure rate due to repeated bending and aging of the cables, and heavy maintenance workload. Compared with existing technologies, this application provides an intelligent suspended transport device for sun visors of new energy vehicles, comprising: Suspension rails are fixed to the top of the factory building via multiple sets of mounting brackets; The traction chain is slidably connected end-to-end to the bottom of the suspension guide rail; The drive unit is used to drive the traction chain forward. A suspension module, comprising several suspension modules evenly spaced at the bottom of the traction chain, includes an L-shaped suspension seat and a clamping plate. The L-shaped suspension seat is mounted to the bottom of the traction chain via a lug structure. Two sets of clamping plates are symmetrically rotatably connected, and two sets of clamping blocks are detachably connected between the two sets of clamping plates. The bottom of each clamping block is provided with a C-shaped clamping groove, which is used to engage and clamp with the assembly shaft of the external sunshade to be conveyed. The L-shaped suspension seat and the clamping plate are also provided with a coaxially sleeved shaft tube and lifting rod, as well as a lever arm one and a lever arm two forming a triangular transmission pair with the shaft tube; a magnetic ring one is provided on the shaft tube, and a magnetic ring two is provided on the lifting rod. Electromagnetic modules, several of which are disposed on the top of the suspension guide rail and correspond to each process station; the electromagnetic modules can control the displacement of the shaft tube and the lifting rod in the vertical direction through the magnetic field, thereby realizing the action of the clamping plate driving the sunshade to rotate, and the action of the clamping plate releasing the sunshade.

[0006] Furthermore, a nut seat is fixed at one bottom end of the L-shaped suspension seat, and a number of equally spaced balls are rotatably connected inside the nut seat. The outer wall of the shaft tube is provided with a spiral groove that cooperates with the balls. The shaft tube is coaxially sleeved inside the nut seat, the magnetic ring is fixed to the top of the shaft tube, and a tension spring is clamped between the magnetic ring and the nut seat.

[0007] Furthermore, the shaft tube is also provided with a spline groove, and a spline shaft that mates with the spline groove is fixed at the top of the lifting rod; the top of the spline shaft extends through the spline groove and is fixed with a second limiting ring, and the second magnetic ring is fixed at the bottom of the spline shaft; the top of the shaft tube extends through the nut seat and is fixed with a first limiting ring, and a second tension spring is clamped between the second magnetic ring and the first limiting ring.

[0008] Furthermore, the first tension spring has an elastic force that drives the shaft tube to move upward, and the second tension spring has an elastic force that drives the lifting rod to move downward; the first magnetic ring and the second magnetic ring have the same magnetism, and the electromagnetic module is configured to output a magnetic field with variable direction.

[0009] Furthermore, the two ends of the second lever arm are rotatably connected to the bottom of the lifting rod and the bottom of the first lever arm, respectively; a rotating seat is fixed to one side of the bottom of the first limiting ring, and the top of the first lever arm is rotatably connected to the rotating seat. The two ends of the lever arm are symmetrically provided with rotating shafts, and the top of each clamping plate is provided with a rotating seat II that is rotatably connected to the rotating shaft; a torsion spring is also provided inside the rotating shaft, and the torsion spring has an elastic force that drives the two sets of clamping plates to rotate closer to each other. The bottom of the clamping plate is symmetrically provided with two sets of oppositely arranged plug-in guide plates.

[0010] Furthermore, each of the two sets of clamping plates is provided with an assembly groove on one side opposite to the clamping plate, and the clamping blocks are provided with symmetrical assembly sliders that cooperate with the assembly grooves on both sides. The clamping block is also provided with an elastic connection node at the top of the C-shaped clamping groove.

[0011] Furthermore, an arc-shaped lever block is fixed to the top of the rotating seat two near the lifting rod of the clamping plate, and the two sets of arc-shaped lever blocks are arranged with their arc-shaped convex surfaces facing each other; a compression ring is provided at one end of the lever arm two near the lifting rod, which cooperates with the arc-shaped convex surface of the arc-shaped lever block; and limiting blocks are symmetrically provided on both sides of the compression ring, which cooperate with the arc-shaped concave surface of the arc-shaped lever block. The thickness of the compression ring along the circumferential direction gradually increases in the direction away from the lifting rod.

[0012] Furthermore, the device is configured such that when the electromagnetic module outputs a repulsive magnetic field acting on magnetic ring one and magnetic ring two, the shaft tube and lifting rod move down synchronously, and the triangular transmission pair composed of the lifting rod, lever arm two, and lever arm one maintains an unchanged angle; the shaft tube drives the clamping plate and the clamped sunshade to rotate through the cooperation of the spiral groove and the ball, adapting to the labeling and visual inspection process.

[0013] Furthermore, the device is configured such that when the electromagnetic module outputs an adsorption magnetic field acting on magnetic ring one and magnetic ring two, the shaft tube moves upward and is locked by the limiting ring one, the lifting rod moves upward alone, and the triangular transmission pair composed of the lifting rod, lever arm two, and lever arm one changes angle. With the relative rotation of lever arm two and the lifting rod, the extrusion ring extrudes the arc-shaped convex surface of the two sets of arc-shaped paddles, overcomes the elastic force of the torsion spring inside the rotating shaft, drives the two sets of clamping plates to rotate away from each other, realizes the release of the clamping plates, and is suitable for the waste material return and good product bagging process.

[0014] Compared to existing technologies, the advantages of this application are: All electromagnetic modules of this device are fixedly arranged above each workstation on the suspended guide rail. The main body of the suspended module, which moves cyclically with the traction chain, does not have any electrical components installed. It does not require the installation of a traveling cable drag chain, thus eliminating the failure of repeated bending of the drag cable and reducing the maintenance workload of the entire conveyor line.

[0015] By using an electromagnetic module to output magnetic fields in different directions for remote driving, and relying on the cooperation of magnetic ring one, magnetic ring two, tension spring one, tension spring two, and triangular transmission pair, a single set of magnetic field excitation can achieve two operating actions: the repulsive magnetic field enables the sunshade to rotate and adjust its posture, and the adsorption magnetic field enables the clamping plate to open and unload the material. This eliminates the need for two sets of independent drive cylinders, simplifies the suspension module structure, and reduces the weight of the suspension module. The tension spring one, tension spring two, and the torsion spring inside the rotating shaft work together to maintain the clamping plate in a state that keeps the sunshade clamped. The sunshade will not fall unexpectedly when the power is off, and the equipment has high safety and reliability. Attached Figure Description

[0018] The embodiments will be described clearly and completely with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application.

[0019] Example: Please refer to Figures 1-12 This embodiment provides an intelligent suspension transport device for new energy vehicle sun visors. This device is used to suspend and transfer the new energy vehicle sun visor 7 between various processes in the production workshop. It should be noted that the sun visor 7 is an external workpiece to be transported and is not a component of this device. Assembly shafts 71 are provided on both sides of the sun visor 7 body, which are the objects to be clamped by this device.

[0020] The entire device is equipped with a suspension guide rail 3, which is fixedly mounted on the steel structure on the roof of the factory building by means of multiple sets of mounting brackets 1. The bottom of the suspension guide rail 3 is equipped with a traction chain 4 that forms a closed loop, which can slide cyclically along the bottom of the suspension guide rail 3. The drive unit 2 is mounted at the end of the suspension guide rail 3. The drive unit 2 outputs power to drive the traction chain 4 to make a continuous forward cyclical motion.

[0021] At the bottom of the traction chain 4, multiple sets of suspension modules 6 are evenly and equidistantly assembled along the chain direction. All suspension modules 6 move synchronously with the traction chain 4 in a circular motion. Above each labeling station, visual inspection station, good product bagging station, and waste material return station, an electromagnetic module 5 is fixedly installed at the corresponding position on the suspension guide rail 3. The electromagnetic module 5 is a fixed station device and does not move with the traction chain 4. After being energized, the electromagnetic module 5 can output two different variable magnetic fields. By relying on the magnetic field, it applies a force to the magnetic ring inside the suspension module 6 passing below the station, thereby triggering the mechanism's action.

[0022] Each set of suspension modules 6 includes an L-shaped suspension seat 61 and two sets of clamping plates 64; the L-shaped suspension seat 61 is assembled and fixed to the bottom of the traction chain 4 by means of its upper lug structure. The two sets of clamping plates 64 are symmetrically arranged and rotatably connected, and the two sets of clamping blocks 67 can be detachably assembled between the two sets of clamping plates 64; the bottom of the clamping block 67 is machined into a C-shaped clamping groove 673, which can be engaged with the assembly shaft 71 of the external sunshade 7 to be conveyed, thus completing the clamping and fixing of the sunshade 7.

[0023] Between the L-shaped suspension seat 61 and the clamping plate 64, a shaft tube 62 and a lifting rod 63 are arranged coaxially and sleeved together. A first lever arm 65 and a second lever arm 66 are also configured, forming a triangular transmission pair structure with the shaft tube 62. A magnetic ring 621 is fixedly installed at the upper part of the shaft tube 62, and a magnetic ring 634 is fixedly installed at the corresponding position of the lifting rod 63. The magnetic field output by the electromagnetic module 5 can control the shaft tube 62 and the lifting rod 63 to produce corresponding displacement changes in the vertical direction. Through these displacement changes, the clamping plate 64, along with the clamped sunshade 7, can be driven to rotate, and the clamping plates 64 can also be driven to open, releasing the clamping constraint on the sunshade 7.

[0024] A nut seat 611 is fixedly installed at the lower end of the L-shaped suspension seat 61. Multiple balls 612, evenly distributed at equal angles, are assembled inside the cavity of the nut seat 611. A spiral groove 624 is formed on the outer wall of the shaft tube 62, and the contour of the groove 624 matches the shape of the balls 612. The shaft tube 62 is coaxially fitted inside the nut seat 611. A magnetic ring 621 is fixed to the top of the shaft tube 62, and a tension spring 623 is clamped between the magnetic ring 621 and the upper surface of the nut seat 611. The tension spring 623 always applies an upward elastic thrust to the shaft tube 62. Without the action of an external magnetic field, the tension spring 623 will push the shaft tube 62 to maintain its initial upper position. When the shaft tube 62 moves vertically up and down, the balls 612 roll along the groove of the spiral groove 624, converting the vertical linear motion of the shaft tube 62 into its own circumferential rotational motion.

[0025] The inner wall of the shaft tube 62 has an axial spline groove 622. The upper end of the lifting rod 63 is fixedly equipped with a spline shaft 632, and the spline shaft 632 and the spline groove 622 are mutually adapted and matched. Relying on the transmission action of the spline pair, the lifting rod 63 and the shaft tube 62 can maintain circumferential synchronous rotation, while the lifting rod 63 can also slide independently relative to the shaft tube 62 in the vertical direction. After the top end of the spline shaft 632 passes through the spline groove 622, a limit ring 631 is fixed thereon, which limits the maximum downward stroke of the lifting rod 63. A magnetic ring 634 is fixed at the lower section of the spline shaft 632. The top end of the shaft tube 62 extends upward through the nut seat 611 and is fixed with a limit ring 626, which limits the maximum upward stroke of the shaft tube 62. A tension spring 633 is sandwiched between magnetic ring 634 and limiting ring 626. The tension spring 633 continuously applies a downward force to the lifting rod 63, keeping it in its initial downward position when there is no external magnetic field. Magnetic rings 621 and 634 are identical in magnetism; when the electromagnetic module 5 outputs magnetic fields of different polarities, they will simultaneously experience repulsive or attractive forces.

[0026] The two ends of lever arm 66 are rotatably connected to the lower ends of lifting rod 63 and lever arm 65, respectively; a rotating seat 625 is fixedly mounted on the side of limiting ring 626, and the upper end of lever arm 65 is hinged to the rotating seat 625. Lever arm 65, lever arm 66, and lifting rod 63 together form a triangular transmission pair structure.

[0027] Rotating shafts 661 are symmetrically arranged at both ends of lever arm 66; rotating seats 641 are respectively arranged on the upper part of the two sets of clamping plates 64, and the rotating seats 641 are rotatably hinged to the rotating shafts 661. Each rotating shaft 661 has a built-in spring, which is a torsion spring structure built into the rotating shaft 661, and has the tendency to drive the two sets of clamping plates 64 to rotate closer to each other. The torsion spring structure inside the rotating shaft 661 continuously outputs elastic torque, thereby driving the two sets of clamping plates 64 to maintain the clamping tendency of moving closer to each other and closing.

[0028] At the lower end of the clamping plate 64, two sets of interlocking guide plates 644 are symmetrically arranged opposite each other. During the process of picking up and putting down the sunshade 7 workpiece, the interlocking guide plates 644 play a guiding role, which facilitates the smooth entry of the assembly shaft 71 into the C-shaped clamping groove 673.

[0029] On the inner sidewalls of the two sets of clamping plates 64 facing each other, there are respectively provided assembly grooves 642; the clamping blocks 67 have integrally formed assembly sliders 671 on both sides, which can be embedded in the assembly grooves 642 to achieve sliding assembly; relying on the cooperation between the assembly sliders 671 and the assembly grooves 642, the clamping blocks 67 can be quickly disassembled and assembled, which is convenient for changing the clamping blocks 67 of the corresponding specifications according to the size of the assembly shaft 71 of different models of sun visors 7. The bottom of the clamping block 67 has a C-shaped clamping groove 673, which is used to fasten and clamp the assembly shaft 71 of the external sun visor 7; the clamping block 67 also has an elastic connecting node 672 above the C-shaped clamping groove 673, which provides elastic cushioning when clamping the sun visor 7 to prevent damage to the assembly shaft 71.

[0030] An arc-shaped lever 643 is fixedly installed on the upper part of the rotating seat 641 on the side of the clamping plate 64 near the lifting rod 63. Two sets of arc-shaped levers 643 are arranged with their convex surfaces facing each other. A compression ring 662 is fixed to one end of the lever arm 66 near the lifting rod 63. The thickness of the compression ring 662 gradually changes along the circumference and gradually increases in the direction away from the lifting rod 63. The compression ring 662 can contact and cooperate with the arc-shaped convex surface of the arc-shaped lever 643. Limiting blocks 663 are also provided on both sides of the compression ring 662. The limiting blocks 663 can fit and limit the maximum opening angle of the clamping plate 64 by engaging with the arc-shaped concave surface of the arc-shaped lever 643, thus preventing the clamping plate 64 from swinging beyond its travel range.

[0031] Combination Figure 11As shown, when the suspension module 6 moves with the traction chain 4 to below the labeling and visual inspection station, the electromagnetic module 5 above the station outputs a repulsive magnetic field. Magnetic ring 621 and magnetic ring 634 are simultaneously subjected to a downward repulsive force. This force overcomes the spring force of tension springs 623 and 633, pushing the shaft tube 62 and lifting rod 63 to move downwards synchronously. Due to the constraints of the spline shaft 632 and spline groove 622, no relative axial sliding occurs between the lifting rod 63 and the shaft tube 62. The overall included angle of the triangular transmission pair composed of lever arm 65, lever arm 66, and lifting rod 63 remains constant.

[0032] During the downward movement of the shaft tube 62, the balls 612 inside the nut seat 611 roll relative to each other along the spiral groove 624 on the outer wall of the shaft tube 62, converting the vertical downward linear displacement of the shaft tube 62 into its own circumferential rotation. The shaft tube 62 drives the triangular transmission pair to rotate as a whole, further driving the clamping plate 64, the clamping block 67, and the sunshade 7 clamped by the C-shaped clamping groove 673 to rotate together, thereby adjusting the workpiece posture of the sunshade 7 to meet the operational requirements of the labeling and visual inspection processes for the orientation of the sunshade 7. During this entire rotation and posture adjustment process, the clamping plate 64 always maintains the clamping state of the sunshade 7 and will not release the workpiece. When the suspension module 6 leaves the magnetic field coverage area of ​​the workstation, under the action of the reset spring force of tension spring 1 623 and tension spring 2 633, the shaft tube 62 and the lifting rod 63 return to their initial positions, and the sunshade 7 rotates and resets.

[0033] Combination Figure 12 As shown, when the suspension module 6 reaches the corresponding station for bagging good products or unloading waste materials, the electromagnetic module 5 at that station switches to output an adsorption magnetic field. The magnetic ring 621 is subjected to an upward adsorption force, driving the shaft tube 62 to move upward until the limiting ring 626 at the upper end of the shaft tube 62 abuts against the limit, locking the shaft tube 62 and preventing it from moving upward further.

[0034] Since magnetic ring 621 and magnetic ring 634 have the same magnetism, magnetic ring 634 will be subject to a greater upward attraction force. This force overcomes the elastic force of tension spring 633 and pushes the lifting rod 63 to move upward relative to the locked shaft tube 62. The upward movement of the lifting rod 63 causes the angle of the triangular transmission pair to change, and the lever arm 66 swings. The compression ring 662 on the lever arm 66 follows the movement. The thickened ring part of the compression ring 662 presses down on the arc-shaped convex surfaces of the arc-shaped lever blocks 643 on both sides. This compression force overcomes the pre-tightening elastic force of the torsion spring structure inside the rotating shaft 661, and pushes the two sets of clamping plates 64 to rotate outward and open. The C-shaped clamping grooves 673 on the clamping blocks 67 separate from each other, releasing the clamping constraint on the sunshade 7 assembly shaft column 71, and completing the operation of unloading and bagging good sunshade 7 or unloading waste sunshade 7.

[0035] As the suspension module 6 continues to move with the traction chain 4 and leaves the magnetic field area of ​​the electromagnetic module 5, the tension spring 623, tension spring 633 and the torsion spring structure inside the rotating shaft 661 release the reset force together, all transmission components return to their initial positions, and the two sets of clamping plates 64 close again, waiting for the next grabbing of the sunshade 7.

[0036] When the entire device is powered off, each spring component maintains its original pre-tension state. The torsion spring structure inside the rotating shaft 661 drives the clamping plate 64 to remain clamped, preventing the safety hazard of the sun visor 7 falling off. At the same time, the clamping block 67 can be quickly disassembled by the assembly slider 671 and the assembly groove 642. It can be replaced simply by pulling it horizontally, making it easy to adapt to various specifications of new energy vehicle sun visors 7.

[0037] The above description is merely the best implementation method adopted in light of current practical needs, but the scope of protection of this application is not limited thereto.
