Description

Technical Field

[0001] This utility model relates to the field of aerial conveying technology, and in particular to an aerial self-propelled trolley conveyor line for conveying semi-finished wire harnesses. Background Technology

[0002] As a key link in the automotive and electronics industries, wire harness production has an increasingly urgent need for efficient transportation of semi-finished products. Overhead self-propelled vehicle conveyor lines have become an important solution for transporting semi-finished wire harness products due to their advantages of high space utilization, flexible layout, and high degree of automation.

[0003] The conveyor line combines suspended tracks with self-driving trolleys to achieve continuous and cyclical transport of wire harness semi-finished products between different workstations, effectively reducing ground space occupation and optimizing workshop production layout. At the same time, its modular design and intelligent control system can dynamically adjust the conveying speed and path according to the production cycle, providing strong support for efficient collaboration in wire harness production. Therefore, it has been applied in modern wire harness manufacturing workshops.

[0004] Traditional tracks, made of ordinary carbon steel or aluminum alloy, bear the weight of the trolley and wiring harness over long periods and are subjected to high-frequency friction, which can lead to wear of the hardened layer on the track surface, grooves on the track surface, or deformation. Existing technologies, by using I-shaped or box-shaped cross-section tracks, can better distribute the weight of the trolley and wiring harness compared to traditional shapes, reducing stress concentration and lowering the risk of deformation. However, in the scenario of conveying semi-finished wiring harnesses, especially in workshops with high ceilings, complex ground auxiliary equipment is usually relied upon. This ground auxiliary equipment not only occupies a lot of ground space but also causes traffic congestion on the workshop floor, affecting the efficiency and stability of material conveying.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of an aerial self-propelled trolley conveyor line for transporting semi-finished wire harnesses, including a slide rail 1 and a slide rail 2. The slide rail 1 and slide rail 2 serve as the basic tracks of the conveyor line, providing a running path for the trolley. A lifting mechanism 3 is provided between adjacent slide rail 1 and slide rail 2. The lifting mechanism 3 can drive the trolley to rise and fall, facilitating the loading and unloading of semi-finished wire harnesses by workers. Locking mechanisms 4 are provided on both the front and rear sides of the lifting mechanism 3. The locking mechanisms 4 can fix the lifting mechanism 3 and unlock it after the trolley reaches the corresponding position. A conveying mechanism 5 is slidably connected to the inner side of slide rail 2. The conveying mechanism 5 carries and transports the semi-finished wire harnesses. A housing 6 is provided on the outer side of the conveying mechanism 5. The housing 6 can protect the internal components of the conveying mechanism 5. A hanging mechanism 7 is provided at the bottom of the inner side of the housing 6. The hanging mechanism 7 is used to suspend the semi-finished wire harnesses. The lifting mechanism 3 includes a lifting slide rail 301, which is one section of the conveying track. The left and right sides of the lifting slide rail 301 are slidably connected to the right side of slide rail 1 and the left side of slide rail 2, respectively. The lifting slide rail 301, slide rail 1, and slide rail 2 form a complete conveying track. A steel plate 302 is fixedly connected to the top of the lifting slide rail 301. The steel plate 302 is used to connect the lifting mechanism 3 and enhance the overall structural strength. A crossbeam 303 is fixedly connected to the top right side of slide rail 1 and the top left side of slide rail 2. The crossbeam 303 serves to connect and support the slide rail 1, slide rail 2, and the lifting mechanism. 3. The two crossbeams 303 are fixedly connected to the top of the same fixed plate 304. The fixed plate 304 provides the mounting base for the hydraulic cylinder 305. The top of the fixed plate 304 is fixedly connected to the hydraulic cylinder 305. The hydraulic cylinder 305 serves as the power source for the lifting mechanism 3, providing the driving force required for lifting. The top of the hydraulic cylinder 305 is fixedly connected to a plate 306. The plate 306 is used to distribute the force of the hydraulic cylinder 305, so that the hydraulic rod 307 is evenly stressed. The top of the plate 306 is fixedly connected to the hydraulic rod 307. The hydraulic rod 307 moves in extension and retraction under the drive of the hydraulic cylinder 305, driving the balance block 308 to rise and fall. A balance block 308 is fixedly connected to the top of the hydraulic rod 307. The balance block 308 is used to balance the force during the lifting process and ensure the smoothness of the lifting movement. Pulleys 309 are fixedly connected to the bottom left and right sides of the balance block 308 and the top left and right sides of the fixed plate 304. The pulleys 309 provide support and guidance for the wire rope. The wire rope is connected to the pulley 309 and transmits the driving force of the hydraulic cylinder 305 to the steel plate 302 and the lifting slide rail 301. The top left and right sides of the fixed plate 304 are provided with through holes 310 to facilitate the wire rope to pass through and connect to the lifting ring 311 below. Lifting rings 311 are fixedly connected to the top left and right sides of 302. When the conveying trolley slides to the position of the lifting slide rail 301, the locking mechanism 4 unlocks, and the hydraulic rod 307 drives the pulley 309 to rise and fall, thereby causing the wire rope to drive the steel plate 302 and the bottom lifting slide rail 301 to rise and fall. Hollow optical shafts 12 are fixedly connected to the four corners of the top of the steel plate 302. The hollow optical shafts 12 cooperate with the guide cylinders 13 to further improve the stability of the lifting mechanism 3. Guide cylinders 13 are fixedly connected to the four corners of the upper and lower sides of the fixed plate 304. The guide cylinders 13 are sleeved on the outside of the hollow optical shafts 12 to ensure that the lifting slide rail 301 rises and falls vertically. Specifically, when the lifting mechanism 3 is working, when the conveying trolley runs along slide rail 1 or slide rail 2 to the position of lifting slide rail 301, the locking mechanism 4 first releases the lock on the lifting slide rail 301. At this time, the hydraulic cylinder 305 fixed at the top of the fixed plate 304 starts, outputting driving force as a power source. The hydraulic cylinder 305 pushes the top plate 306, and the plate 306 evenly distributes the force of the hydraulic cylinder 305 to the hydraulic rod 307. The hydraulic rod 307 performs telescopic movement under the drive of the hydraulic cylinder 305. When the hydraulic rod 307 extends downward, it drives the top balance block 308 to descend. The pulleys 309 fixed on the left and right sides of the bottom of the balance block 308 descend accordingly. The steel wire rope connected to the pulley 309 passes through the through holes 310 opened on the left and right sides of the top of the fixed plate 304 to transmit the tension to the lifting rings 311 fixed on the left and right sides of the top of the steel plate 302. Since the steel plate 302 is fixed to the top of the lifting slide rail 301, it pulls the... The steel plate 302 and the bottom lifting slide rail 301 descend synchronously. During this process, the hollow optical shafts 12 fixed at the four corners of the top of the steel plate 302 cooperate with the guide cylinders 13 fixed at the four corners of the upper and lower sides of the fixed plate 304 to ensure that the lifting slide rail 301 descends smoothly in the vertical direction. When it is necessary to raise the lifting slide rail 301, the oil cylinder 305 moves in the opposite direction, the hydraulic rod 307 retracts upward, pulling the balance block 308 and the pulley 309 upward. The wire rope drives the steel plate 302 and the lifting slide rail 301 to return to the starting position. The balance block 308 plays a role in balancing the force during the lifting process, preventing the lifting slide rail 301 from tilting or shaking. Finally, after the lifting slide rail 301 rises to a position flush with slide rail 1 and slide rail 2, the locking mechanism 4 locks the lifting slide rail 301 again, so that the lifting slide rail 301 forms a complete conveying track with slide rail 1 and slide rail 2, so that the conveying trolley can continue to run.

[0020] Reference Figure 1 , Figure 2 and Figure 3The locking mechanism 4 includes multiple fixing blocks 401, which are used to install bending columns 402. The adjacent sides of the front and rear fixing blocks 401 are fixedly connected to the bottom of the front and rear sides of the lifting slide rail 301, respectively, to achieve a fixed assembly between the locking mechanism 4 and the lifting slide rail 301. The tops of the multiple fixing blocks 401 are slidably connected to bending columns 402. The bending columns 402 can lock and unlock the lifting slide rail 301 with slide rail 1 and slide rail 2 by sliding. The bottom ends of the multiple bending columns 402 penetrate the tops of the multiple fixing blocks 401. A top plate 403 is fixedly connected to the middle of the outer side of each of the multiple bending columns 402. The top plate 403 is used to connect a return spring 404. The bottoms of the multiple top plates 403 are fixedly connected to a return spring 404. The return spring 404 can provide a reset force to the bending column 402 after the locking action is released. Side plates 405 are fixedly connected to the front and rear right ends and the front and rear left ends of slide rail 2. Positioning holes 406 are opened on the side plates 405 to provide positioning and locking points for the bending column 402. Positioning holes 406 are opened on the right side of the left side plate 405 and the left side of the right side plate 405. The positioning holes 406 cooperate with the bending column 402 to achieve precise locking of the lifting slide rail 301 in the designated position. Guide holes 10 are opened on the top left and right sides of the multiple top plates 403. The guide holes 10 provide a sliding channel for the guide column 11 to guide the sliding direction of the top plate 403 and the bending column 402. The guide columns 11 are slidably connected inside the multiple guide holes 10. The guide columns 11 cooperate with the guide holes 10 to improve the stability of the bending column 402 during the sliding process. The bottom of the multiple guide columns 11 is fixedly connected to the top of the multiple fixed blocks 401 to ensure that the guide columns 11 and the bending column 402 slide at the same time. Specifically, when the locking mechanism 4 is working, the bent column 402, under the tension of the return spring 404, inserts its inclined end into the positioning hole 406. At this time, the bent column 402, through its cooperation with the positioning hole 406, securely locks the lifting slide rail 301 to slide rail 1 and slide rail 2. The return spring 404 fixed at the bottom of the top plate 403 is in its normal state. When the conveying trolley slides to the bottom of the lifting slide rail 301, the top of the outer shell 6 presses against the bent column 402, and the guide column 11 cooperates with the guide holes 10 opened on the left and right sides of the top of the top plate 403 to ensure... The bending column 402 slides vertically and disengages from the positioning hole 406 of the side plate 405. At this time, the lifting slide rail 301 is unlocked and can be lifted. After the lifting is completed, the conveying trolley continues to move, the external force applied to the bending column 402 is released, the return spring 404 returns to its deformation, the top plate 403 and the bending column 402 are reset, and the bending column 402 is reinserted into the positioning hole 406 of the side plate 405 under the guidance of the guide column 11 and the guide hole 10, and the lifting slide rail 301 is locked with slide rail 1 and slide rail 2 again.

[0021] Reference Figure 4 , Figure 5and Figure 6 The conveying mechanism 5 includes an upper support 501, which is used to mount the conveying trolley. The front and rear sides of the upper support 501 are slidably connected to the inner front and rear sides of the slide rail 2, respectively. Two guide wheels 502 are rotatably connected to the top of the front and rear sides of the upper support 501. The guide wheels 502 can slide on the slide rail 2 and play a guiding role, making the conveying mechanism 5 run more smoothly. The bottom left end of the front and rear sides of the upper support 501 is rotatably connected to the same connecting column 503. The connecting column 503 is used to connect the mounting plate 504, so that the power transmission structure is stably connected to the upper support 501. The mounting plate 504 is fixedly connected to the front and rear sides of the connecting column 503. The mounting plate 504 provides the mounting position for the servo motor 505 and the rolling wheel 506. The servo motor 505 is fixedly connected to the rear side of the rear mounting plate 504. 505 serves as the power source for the conveying mechanism 5. By driving the roller 506 to rotate, it moves the conveying mechanism 5 on the slide rail 2. The roller 506 is rotatably connected between the two adjacent mounting plates 504. The roller 506 rotates under the drive of the servo motor 505, generating friction with the track to achieve the movement of the conveying mechanism 5. The output end of the servo motor 505 passes through the middle of the rear mounting plate 504 and is rotatably connected to the rear side of the roller 506, so that the power of the servo motor 505 can be effectively transmitted to the roller 506. An adjustment component 507 is provided on the bottom right side of the upper bracket 501. The adjustment component 507 is used to compensate for the distance between the roller 506 and the track. By adjusting the position of the roller 506, it is ensured that the conveying mechanism 5 maintains a good contact state with the track, thereby achieving stable operation. The adjusting assembly 507 includes a rotating block 5071. The front and rear sides of the rotating block 5071 are rotatably connected to the bottom right end of the front and rear sides of the upper bracket 501. The rotating block 5071 can rotate around the upper bracket 501, providing rotational support for the threaded rod 5072. The threaded rod 5072 is fixedly connected to the bottom of the rotating block 5071. The threaded rod 5072 moves axially by rotation, thereby adjusting the distance between the rolling wheel 506 and the track. A connecting plate 5073 is fixedly connected to the right side between the two adjacent mounting plates 504. The connecting plate 5073 is used to connect the threaded rod 5072 and the mounting plate 504, so that the adjusting assembly 507... The connecting plate 5073 is integrated with the conveying mechanism 5. The top outer side of the connecting plate 5073 extends through the middle of the connecting plate 5073, ensuring that the threaded rod 5072 can freely pass through the connecting plate 5073 and move axially. A butterfly spring 5074 is slidably connected to the middle outer side of the threaded rod 5072. The butterfly spring 5074 provides elastic force, enabling the rolling wheel 506 to adapt to the unevenness of the track and maintain stable contact. A nut 5075 is threadedly connected to the bottom outer side of the threaded rod 5072. By tightening or loosening the nut 5075, the position of the threaded rod 5072 can be fixed, the adjusted distance can be locked, and the stability of the adjustment effect can be ensured. Specifically, when the conveying mechanism 5 is running, the servo motor 505 starts, driving the rolling wheel 506 to rotate. The rotating wheel 506 generates friction with the track, causing the upper support 501 and the entire conveying mechanism 5 to move along the slide rail 2, thus conveying the semi-finished wire harness. Simultaneously, the guide wheel 502 slides along the front and rear sides of the slide rail 2, providing guidance and support for the conveying mechanism 5, ensuring smooth operation. When there is a deviation in the distance between the rolling wheel 506 and the track, or when the track surface is uneven, the adjusting component 507 starts working, rotating the rotating block 5071 to drive the threaded rod 5072 fixed at the bottom to rotate. The threaded rod 5072 moves axially under the limit of the connecting plate 5073. The butterfly spring 5074, which is slidably connected to the middle of the outer side of the threaded rod 5072, provides elastic force when the threaded rod 5072 moves, so that the rolling wheel 506 can adapt to the height changes of the track. After adjusting to the appropriate position, tighten the nut 5075, which is threaded to the bottom of the outer side of the threaded rod 5072, to fix the position of the threaded rod 5072, thereby locking the distance between the rolling wheel 506 and the track, ensuring that the rolling wheel 506 maintains good contact with the track, and realizing the stable operation and adaptive adjustment of the conveying mechanism 5 on the slide rail 2.

[0022] Reference Figure 4 and Figure 5 The hanging mechanism 7 includes two lower supports 701, which provide an installation base for the hanging ring 703 and are used to support and suspend the wire harness semi-finished products. The left and right sides of the two lower supports 701 are respectively fixedly connected to the bottom of the left and right sides inside the outer shell 6 to realize the fixed connection between the hanging mechanism 7 and the outer shell 6. There are two pins 702 rotatably connected between the front and rear sides of the two lower supports 701. The pins 702 provide a rotation fulcrum for the hanging ring 703, which facilitates the suspension and removal of the wire harness semi-finished products. The outer sides of the multiple pins 702 are slidably connected to the hanging ring 703, which is used to suspend the wire harness semi-finished products. The front side of the front mounting plate 504 is fixedly connected to the battery compartment 8, which is used to house the battery 9 and provide power storage space for the electrical components of the conveying mechanism 5. The bottom of the inner side of the battery compartment 8 is fixedly connected to the battery 9, which supplies power to the servo motor 505 electrical equipment to ensure the autonomous operation of the conveying mechanism 5. Specifically, when using the hanging mechanism 7, firstly, the two lower supports 701 achieve a stable connection between the hanging mechanism 7 and the outer casing 6, providing a foundation for subsequently carrying the semi-finished wire harness. Then, by storing the semi-finished wire harness in the storage box and hanging the storage box on multiple hanging rings 703, the wire harness is suspended and fixed. At the same time, the battery 9 provides power support for the electrical equipment of the entire conveying mechanism 5. The electrical energy stored in the battery 9 is transmitted to the servo motor 505, ensuring that the servo motor 505 can drive the rolling wheel 506 to rotate, thereby driving the conveying mechanism 5 to move on the slide rail 2. During this process, the lower supports 701 continuously provide support for the hanging rings 703, ensuring that the suspended semi-finished wire harness remains stable during the conveying process, and realizing the efficient conveying of the semi-finished wire harness from one workstation to another.

[0023] Working principle: First, the conveying mechanism 5 carries the semi-finished wire harness and slides along the slide rail 2. When the conveying trolley slides to the position of the lifting slide rail 301, the hydraulic cylinder 305 is activated as the power source. The hydraulic cylinder 305 pushes the plate 306, which in turn drives the hydraulic rod 307 to move downward. The hydraulic rod 307 drives the balance block 308 to descend, and the pulley 309 at the bottom of the balance block 308 descends accordingly. The steel wire rope connected to the pulley 309 transmits the tension to the steel plate 30 through the through hole 310 of the fixing plate 304. 2. The top lifting ring 311 drives the steel plate 302 and the bottom lifting slide rail 301 to descend, and the conveying trolley also descends. At this time, the staff can conveniently load and unload the semi-finished wire harness. After loading and unloading, the oil cylinder 305 moves in the opposite direction, the hydraulic rod 307 extends, and pulls the steel plate 302 and the lifting slide rail 301 to rise through the wire rope. During this process, the hollow optical shaft 12 cooperates with the guide cylinder 13 to ensure that the lifting slide rail 301 rises and falls vertically. The balance block 308 plays a role in balancing the force and ensuring that the lifting process is stable. Furthermore, as the conveying trolley slides onto the lifting slide rail 301, the top of the outer casing 6 presses against the bending column 402, causing the bending column 402 to disengage from the positioning hole 406 in the side plate 405, thus unlocking the mechanism. After the lifting slide rail 301 rises back to its original position, the conveying trolley continues to slide along the track. Under the action of the return spring 404, the bending column 402 of the locking mechanism 4 re-inserts into the positioning hole 406 in the side plate 405, fixing the lifting mechanism 3. When the distance between the rolling wheel 506 and the track deviates during operation, the adjusting component 507 can compensate. Rotating the rotating block 5071 drives the threaded rod 5072 to rotate. The threaded rod 5072 moves axially in the connecting plate 5073. The butterfly spring 5074 provides elastic force to adapt to uneven track conditions. By tightening or loosening the nut 5075, the adjusted distance can be locked to ensure that the rolling wheel 506 maintains good contact with the track.
