[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] In related technologies, due to production process requirements and site layout constraints, some conveyor lines are designed to be excessively long. Overly long conveyor lines occupy a significant amount of floor space, increasing site costs and impacting the layout of other equipment and production process optimization.

[0034] To address the aforementioned problems, this application proposes a multi-layer transmission line 100, which is primarily used for transporting products. The multi-layer transmission line 100 may include belt conveyors, chain conveyors, spiral conveyors, magnetic drive conveyors, etc., and this application does not specifically limit the type. The following description uses a magnetic drive transmission line as an example of the multi-layer transmission line 100.

[0035] Please see Figure 1 The multilayer transmission line 100 includes an upper transmission line 10 and a lower transmission line 20 that are opposite each other, a first upper and lower connection mechanism 30, and an optical fiber line 40.

[0036] Specifically, the upper transmission line 10 includes multiple upper stators, including an upper end stator 15 located at the end of the transmission direction of the upper transmission line 10, and the lower transmission line 20 includes multiple lower stators, including a lower beginning stator 21 located at the beginning of the transmission direction of the lower transmission line 20. The upper end stator 15 and the lower beginning stator 21 are arranged vertically opposite each other.

[0037] It should be noted that, with the ground where a person stands as a reference, the lower transmission line 20 is located at a relatively low position close to the ground, while the upper transmission line 10 is located at a higher position in space.

[0038] The first upper and lower connecting mechanism 30 includes a first upper and lower connecting drive component 31 and a first upper and lower connecting stator 32 disposed on the first upper and lower connecting drive component 31. The first upper and lower connecting drive component 31 is used to drive the first upper and lower connecting stator 32 to move, so that the first upper and lower connecting stator 32 moves upward and splices with the upper end stator 15 or moves downward and splices with the lower beginning stator 21.

[0039] The first upper and lower connecting drive assembly 31 can be made of components such as electric cylinders, pneumatic cylinders, or linear motors. Electric cylinders convert rotary motion into linear motion via a servo motor and ball screw, achieving high positioning accuracy. Pneumatic cylinders are driven by compressed air, resulting in a simple structure and low cost. Linear motors can directly convert electrical energy into linear motion, providing rapid response. These drive assemblies can be paired with a position detection device and work in conjunction with a controller to drive the first upper and lower connecting stator 32, enabling it to connect upwards to the upper end stator 15 or downwards to the lower beginning stator 21.

[0040] The carrier component of the multi-layer conveyor line in this application is called a mover, which typically contains a permanent magnet or an electromagnet. The upper stator, lower stator, and the first upper and lower connecting stator 32 are equipped with linear windings. When a product is placed on the mover, the permanent magnet or electromagnet on the mover magnetically couples with the linear windings. Under the influence of the magnetic field generated by the coils, the mover moves along the transmission direction corresponding to the splicing direction of the upper stator, lower stator, and the first upper and lower connecting stator 32, thereby achieving product transport.

[0041] The fiber optic cable 40 connects the upper end stator 15, the first upper and lower connecting stator 32, and the lower beginning stator 21 in series. Compared with the signal transmission method of traditional transmission lines, the fiber optic cable 40 has advantages such as strong anti-interference ability, low signal attenuation, and fast transmission rate. It can ensure the stability and timeliness of signal transmission between stators and avoid abnormal operation of the mover due to signal transmission delay or interference.

[0042] Based on the above embodiments, by setting up an upper transmission line 10 and a lower transmission line 20 that are vertically opposite each other, and making the lower first-end stator 21 and the upper end stator 15 vertically opposite each other, and cooperating with the first upper and lower connection drive assembly 31 that can drive the first upper and lower connection stator 32 to move, vertical connection of materials between the upper and lower transmission lines 20 is realized, shortening the transmission path length, reducing the plane space occupation, optimizing the site layout, and reducing site costs. In addition, by connecting the upper end stator 15, the first upper and lower connection stator 32, and the lower first-end stator 21 in series with optical fiber lines 40, the stability and timeliness of signal transmission between each stator are ensured, thereby improving the overall transmission efficiency and stability of the multi-layer transmission line 100, which is conducive to the smooth operation and optimization of the production process, while reducing the number of optical fiber lines 40, thereby reducing manufacturing costs.

[0043] It should be noted that, Figure 1 When fiber optic cables 40 are connected in series, black represents the input end of fiber optic cable 40, and white represents the output end of fiber optic cable 40.

[0044] Reference Figure 1 In some embodiments of this application, the lower stator further includes a first lower arc-shaped stator 22, a first lower straight stator 23, a second lower arc-shaped stator 24, and a lower end stator 25 arranged sequentially along the transmission direction of the lower transmission line 20. The end of the first lower arc-shaped stator 22 facing away from the first lower straight stator 23 is spliced ​​with the lower beginning stator 21. This combination of arc-shaped and straight stators cleverly extends the actual transmission length of the lower transmission line within a limited ground space. The mover performs straight-line transport on the first lower straight stator 23, and with the turning transition of the first lower arc-shaped stator 22 and the second lower arc-shaped stator 24, a circuitous extension of the transmission path is achieved, thus avoiding the need for an excessively long straight distance on the ground and effectively saving space.

[0045] The feed end of the lower first stator 21 and the discharge end of the lower last stator 25 are located on the same side of the first lower linear stator 23, further optimizing the transmission process. This design makes the input and output of materials more spatially concentrated, facilitating rapid scheduling of the conveying process and reducing adjustments. Simultaneously, it makes the connection between the lower transmission line 20 and other ground production equipment and storage areas more convenient, resulting in a more compact and orderly overall layout, further improving the utilization efficiency of site space and the smoothness of the production process.

[0046] Furthermore, the fiber optic line 40 connects the lower-layer first-end stator 21, the first lower-layer curved stator 22, the first lower-layer straight stator 23, the second lower-layer curved stator 24, and the lower-layer end stator 25 in series. This series connection enables high-speed and stable communication between all stators in the lower-layer transmission line 20. The fiber optic line 40's strong anti-interference capability and low signal attenuation ensure the accuracy and timeliness of control signal transmission for each stator. Whether it's the linear transport of the mover on the first lower-layer straight stator 23 or the steering control when passing the first lower-layer curved stator 22 and the second lower-layer curved stator 24, each stator can coordinate its operation based on the precise commands transmitted by the fiber optic line 40. This allows the lower-layer transmission line 20 to achieve long-distance transmission within a limited space while precisely controlling the mover's operating state, avoiding transport deviations caused by signal transmission delays or interference, further improving the overall stability and reliability of the multi-layer transmission line 100, and ensuring efficient and smooth production processes.

[0047] In some embodiments, the lower-level first-end stator 21 and the upper-level last-end stator 15 are of the same type, both being one of the following: straight stator, arc stator, bifurcated stator, and cross stator. This design brings high flexibility and adaptability to the layout of the transmission line. When both use straight stators, direct vertical connection of the mover between the upper and lower layers can be achieved, reducing turning losses. If an arc stator is selected, the mover can complete the inter-layer transition with a smoother trajectory, reducing the impact of motion inertia. When a bifurcated stator or a cross stator is used, the needs of multi-path material diversion or merging can be met, making it easier for the upper and lower layer transmission lines 20 to connect with other branch transmission systems. The same type of stator not only ensures the consistency of the motion characteristics of the mover when switching between upper and lower layers, reducing the speed adjustment and path calibration links caused by stator structure differences, but also realizes the commonality of parts, reduces production and maintenance costs, and further improves the space utilization efficiency and transmission efficiency of the multi-layer transmission line 100 in different production scenarios.

[0048] To further optimize the three-dimensional transmission performance of the multilayer transmission line 100, refer to Figure 1 In some embodiments, the multilayer transmission line 100 further includes a second upper and lower connection mechanism 50. The second upper and lower connection mechanism 50 includes a second upper and lower connection driving component 51 and a second upper and lower connection stator 52 disposed on the second upper and lower connection driving component 51. The upper stator includes an upper first-end stator 11 located at the beginning of the transmission direction of the upper transmission line 10, and a lower end stator 25 disposed vertically opposite to the upper first-end stator 11. The second upper and lower connection driving component 51 is used to drive the second upper and lower connection stator 52 to move, so that the second upper and lower connection stator 52 moves upward and connects with the upper first-end stator 11 or moves downward and connects with the lower end stator 25.

[0049] The lower end stator 25 and the upper beginning stator 11 are of the same type, namely, a straight stator, an arc stator, a bifurcated stator, and a cross stator. This allows the second upper and lower connecting stators 52 to be seamlessly connected during splicing, providing a basis for the smooth transition of the mover.

[0050] By setting up a second upper and lower connecting mechanism 50, the upper conveyor line 10 and the lower conveyor line 20 are designed for bidirectional connection. This establishes a dual-loop conveying path between the upper and lower conveyor lines 10 and 20 without increasing the floor space required. This not only significantly improves the conveying efficiency and flexibility of the multi-layer conveyor line 100, but also allows for flexible adjustment of the material conveying direction and flow according to production process requirements, thus significantly enhancing the space utilization and production adaptability of the entire conveying system. Taking the actual production process as an example: Unprocessed products can first be placed on the mover located at the lower end stator 25. The mover is spliced ​​with the upper first end stator 11 via the second upper and lower connecting stator 52 and transferred to the upper transmission line 10 for processing. After processing is completed, the mover is transferred from the upper end stator 15 to the first upper and lower connecting stator 32 and the lower first end stator 21 via the first upper and lower connecting mechanism 30. After the processed products are taken away, the empty mover returns to the lower end stator 25 to start a new round of transportation, which significantly enhances the space utilization and production adaptability of the entire transmission system.

[0051] It is worth mentioning that the second upper and lower connecting mechanism 50 can have the same structure as the first upper and lower connecting mechanism 30, and can be driven by electric cylinders, pneumatic cylinders, linear motors, etc., to facilitate standardized production and manufacturing.

[0052] Furthermore, the fiber optic cable 40 connects the lower-level end stator 25 and the second upper / lower connecting stator 52 in series. Through the low-loss and interference-resistant signal transmission characteristics of the fiber optic cable 40, precise signal interaction can be achieved between the lower-level end stator 25, the second upper / lower connecting stator 52, and other series-connected stators, ensuring real-time synchronization of control commands during the connection process. When the second upper / lower connecting stator 52 is spliced ​​upwards to the upper-level first-level stator 11, the precise signal transmitted by the fiber optic cable 40 ensures that the magnetic field parameters and drive logic of both remain consistent, avoiding stuttering or positional deviation of the mover during inter-layer switching due to signal delay. When docking downwards with the lower-level end stator 25, the synchronized signal interaction allows for a smooth transition of the mover between different stators, effectively improving the stability of the connection process and ensuring the continuity and reliability of the mover transmission path.

[0053] Reference Figure 1Optionally, the upper stator further includes a first upper arc-shaped stator 12, a first upper linear stator 13, and a second upper arc-shaped stator 14 arranged sequentially along the transmission direction of the upper transmission line 10. The end of the second upper arc-shaped stator 14 facing away from the first upper linear stator 13 is spliced ​​to the upper end stator 15, and the upper beginning stator 11 is spliced ​​to the end of the first upper arc-shaped stator 12 facing away from the first upper linear stator 13. The first lower arc-shaped stator 22 and the second upper arc-shaped stator 14 are arranged vertically opposite each other, the first lower linear stator 23 and the first upper linear stator 13 are arranged vertically opposite each other, and the second lower arc-shaped stator 24 and the first upper arc-shaped stator 12 are arranged vertically opposite each other.

[0054] This mirror-symmetric setup of the upper and lower stators allows the mover to smoothly transition along a pre-matched arc or straight trajectory when switching between the upper and lower transmission lines 20, reducing speed fluctuations and positional shifts caused by sudden changes in direction. This effectively improves the stability and smoothness of the mover as it shuttles between the multiple transmission lines 100, ensuring the efficiency and accuracy of the material transfer process.

[0055] Furthermore, the fiber optic line 40 connects the upper-level first-end stator 11 in series with the first upper-level arc-shaped stator 12, the first upper-level straight stator 13, the second upper-level arc-shaped stator 14, and the upper-level end stator 15. Through this comprehensive series connection, a low-latency, high-interference-resistance communication link is established between the key stators of the upper-level transmission line 10. When the mover moves along the upper-level transmission line 10, whether at the turning point of the first upper-level arc-shaped stator 12, the straight-line transmission stage of the first upper-level straight stator 13, or the transition to the end via the second upper-level arc-shaped stator 14, each stator can quickly and accurately exchange control signals and operating status information using the fiber optic line 40. This ensures that the mover receives coordinated support from all stators throughout the entire upper-level transmission process, effectively avoiding operational delays or positioning deviations caused by poor signal transmission, greatly improving the stability and reliability of the mover's operation on the upper-level transmission line 10, and guaranteeing the efficient and smooth material transfer process.

[0056] Optionally, the multi-layer transmission line 100 also includes a first distribution box (not shown), which includes a first distribution module (not shown) and a first power line P4. It is understood that the first distribution module can be connected to a 380V or 220V power supply voltage. One end of the first power line P4 is electrically connected to the first distribution module, and the other end is electrically connected to the first upper and lower connecting stator 32, the lower first-end stator 21, and the first lower arc-shaped stator 22, so that the first distribution module supplies power to the first upper and lower connecting stator 32, the lower first-end stator 21, and the first lower arc-shaped stator 22. Since the power supply voltage of the first power distribution module is limited, and the power required by the first upper and lower connecting stator 32, the lower first-end stator 21, and the first lower arc-shaped stator 22 is fixed, if the first power line P4 connects to a large number of stators, it can easily affect the voltage it provides. That is, the longer the length of the first power line P4, the greater the resistance, and the voltage input to the first upper and lower connecting stator 32, the lower first-end stator 21, and the first lower arc-shaped stator 22 will decrease, reducing the reliability of the power supply. However, the first power distribution module in this embodiment only supplies power to the first upper and lower connecting stator 32, the lower first-end stator 21, and the first lower arc-shaped stator 22, thus ensuring the stable operation of the first upper and lower connecting stator 32, the lower first-end stator 21, and the first lower arc-shaped stator 22.

[0057] Optionally, the multilayer transmission line 100 further includes a second distribution box (not shown), which includes a second distribution module (not shown) and a second power line P5. One end of the second power line P5 is electrically connected to the second distribution module, and the other end is electrically connected to the first lower linear stator 23, so that the second distribution module supplies power to the first lower linear stator 23.

[0058] Understandably, the second power distribution module can be connected to a 380V or 220V power supply. One end of the second power line P5 is electrically connected to the second power distribution module, and the other end is electrically connected to the first lower linear stator 23, so that the second power distribution module supplies power to the first lower linear stator 23. Since the power supply voltage of the second power distribution module is limited, and the power required by the first lower linear stator 23 is fixed, if the second power line P5 is connected to more stators, it can easily affect the voltage it provides. That is, the longer the length of the second power line P5, the greater the resistance, and the voltage input to the first lower linear stator 23 will decrease, reducing the reliability of the power supply. However, in this embodiment, the second power distribution module only supplies power to the first lower linear stator 23, thus ensuring the stable operation of the first lower linear stator 23.

[0059] Optionally, the multilayer transmission line 100 also includes a third distribution box (not shown), which includes a third distribution module (not shown) and a third power line P6. One end of the third power line P6 is electrically connected to the third distribution module, and the other end is electrically connected to the second lower arc-shaped stator 24, the lower end stator 25 and the second upper and lower connecting stator 52, so as to supply power to the second lower arc-shaped stator 24, the lower end stator 25 and the second upper and lower connecting stator 52.

[0060] Understandably, the third power distribution module can be connected to a 380V or 220V power supply voltage. One end of the third power line P6 is electrically connected to the third power distribution module, and the other end is electrically connected to the second lower arc-shaped stator 24, the lower end stator 25, and the second upper and lower connecting stator 52, so that the third power distribution module supplies power to the second lower arc-shaped stator 24, the lower end stator 25, and the second upper and lower connecting stator 52. Since the power supply voltage of the third power distribution module is limited, and the power required by the second lower arc-shaped stator 24, the lower end stator 25, and the second upper and lower connecting stator 52 is fixed, if too many stators are connected to the third power line P6, it will easily affect the voltage it provides. That is, the longer the length of the third power line P6, the greater the resistance, and the voltage input to the second lower arc-shaped stator 24, the lower end stator 25, and the second upper and lower connecting stator 52 will decrease, reducing the reliability of power supply. However, the third power distribution module of this application embodiment only supplies power to the second lower arc-shaped stator 24, the lower end stator 25, and the second upper and lower connecting stator 52, so it can ensure the stable operation of the second lower arc-shaped stator 24, the lower end stator 25, and the second upper and lower connecting stator 52.

[0061] In some embodiments, the layout design of the fiber optic cable 40 fully considers the dynamic movement requirements of the first upper and lower connecting stators 32. The fiber optic cable 40 includes a first movable segment (not shown), which is connected to the first upper and lower connecting stators 32 and between the upper end stator 15 and the lower beginning stator 21 connected to the first upper and lower connecting stators 32. The multilayer transmission line 100 also includes a first drag chain (not shown) wrapped around the first movable segment.

[0062] The first drag chain can be a mechanical protective device composed of multiple chain links, made of high-strength engineering plastics or metal materials. Each chain link is connected to each other by hinges, forming a flexible and bendable chain structure, which not only provides reliable physical protection for the internal optical fiber 40, but also allows the optical fiber 40 to move freely within a certain range. As a mechanical protective device, the first drag chain can not only effectively prevent the optical fiber 40 from being damaged by friction and collision with other components during movement, but also guide the first moving section to move along a preset path, avoiding entanglement or excessive bending. This structural design not only ensures the service life of the optical fiber 40 in dynamic environments, but also maintains the stability of signal transmission, enabling the first upper and lower connecting mechanism 30 to still achieve high-speed and reliable communication with the upper end stator 15 and the lower end stator 21 through the optical fiber 40 during frequent connecting operations, thereby ensuring the smooth transition and precise control of the mover between the upper and lower transmission lines 20.

[0063] Similarly, to ensure the stable operation of the second upper and lower connection mechanism 50, the fiber optic cable 40 is also provided with a second movable section (not shown). The second movable section is connected between the second upper and lower connection stator 52 and the upper first-end stator 11 and lower end stator 25 connected to the second upper and lower connection stator 52. As the second upper and lower connection stator 52 moves up and down under the control of the second upper and lower connection drive assembly 51, the second movable section can flexibly extend, retract, and bend, ensuring that signal transmission is not affected by the connection action. Correspondingly, the transmission line is equipped with a second drag chain that wraps around the second movable section. Its structure is similar to that of the first drag chain, and it is made of high-strength chain links hinged together. The second drag chain protects the second movable section from external mechanical damage while regulating its movement trajectory, avoiding signal attenuation or fiber breakage caused by irregular bending. In this way, when the second upper and lower connecting mechanism 50 completes the connection between the upper first stator 11 and the lower last stator 25, the second moving section, in conjunction with the second drag chain, can achieve stable signal transmission and facilitate the efficient transfer of the mover between the upper and lower transmission lines 20.
