[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-9 The present invention discloses a portable mobile digital twin production line scheduling device, comprising a digital twin production line scheduling cabinet 1, a base frame 2 fixedly mounted at the lower end of the digital twin production line scheduling cabinet 1, and support components at the four corners of the base frame 2. The support components include support legs 3, support rods 10, a first rotating shaft 15, and bottom wheels 12. A slot 4 is provided above the support legs 3, and a fixing box 5 is provided above the slot 4. The fixing box 5 is fixed at the lower end of the digital twin production line scheduling cabinet 1. A first cavity 9 is provided inside the support legs 3, and an assembly groove 8 is provided at the bottom of the first cavity 9. The support rod 10 passes through the first cavity 9 and slides with the first cavity 9. A cylindrical rod 11 is fixed at the bottom end of the support rod 10, passes through the assembly groove 8, and a bottom wheel 12 is provided at the lower end of the cylindrical rod 11.

[0033] The lower end of the support leg 3 is provided with a base 6, and the upper end of the base 6 is fixedly provided with a vertical rod 7. The vertical rod 7 is inserted into the assembly groove 8 and threadedly connected to the assembly groove 8. The base 6 is provided with a second cavity 14, the cylindrical rod 11 passes through the vertical rod 7, and the bottom wheel 12 can be stored in the second cavity 14.

[0034] The first rotating shaft 15 vertically penetrates the fixed box 5, and the first rotating shaft 15 and the fixed box 5 are rotatably connected by the first bearing. The lower end of the first rotating shaft 15 is provided with a threaded rod 13 inserted into the support rod 10. The threaded rod 13 is threadedly connected to the support rod 10. The lower end of the digital twin production line scheduling cabinet 1 is provided with a drive assembly that drives multiple first rotating shafts 15 to rotate synchronously.

[0035] Control principle of digital twin production line scheduling cabinet 1:

[0036] Core scheduling logic control:

[0037] The digital twin production line scheduling cabinet 1 serves as the core control center of the device. It integrates a digital twin modeling module, a data acquisition and transmission module, a scheduling decision module, and a device status control module, thereby achieving integrated management and control of production scheduling and the device's own status.

[0038] Digital twin mirror construction: The scheduling cabinet connects to various production equipment on the physical production line through the data acquisition module, and collects data such as equipment operating parameters, process progress, and material inventory in real time. After the data is cleaned and synchronized by the transmission module, the digital twin modeling module constructs a digital twin mirror that maps to the physical production line in a 1:1 manner, providing an accurate virtual simulation basis for subsequent scheduling decisions.

[0039] Intelligent scheduling decision-making: The scheduling decision-making module, based on a digital twin image and combined with preset production scheduling algorithms and fault early warning models, dynamically optimizes the allocation of production line resources. When an abnormality is detected in the production line equipment, a fault handling plan is automatically generated; when an urgent order is received, the resource allocation of temporary workstations can be completed quickly. At the same time, this module will link with the device's own status control module to determine whether the scheduling cabinet needs to be moved to the field location.

[0040] Stationary working state:

[0041] When the digital twin production line scheduling device is in the normal scheduling operation state, the overall structure's support and protection system is in the initial deployment state.

[0042] The digital twin production line scheduling cabinet 1 serves as the core scheduling unit. Its lower end is fixed with a positioning plate by screws. The positioning plate assists the fixing box 5 in completing precise assembly. The fixing box 5 is stably installed at the lower end of the digital twin production line scheduling cabinet 1, providing protection and installation carrier for the drive and transmission components.

[0043] The base frame 2 at the bottom of the digital twin production line scheduling cabinet 1 is equipped with support components at all four corners. Each support component has a slot 4 above the support leg 3. The support rod 10 passes through the first cavity 9 inside the support leg 3, and the outer wall of the support rod 10 is tightly fitted with the inner wall of the first cavity 9. At the same time, the cross section of the support rod 10 is rectangular, which can prevent it from rotating or shifting inside the cavity.

[0044] The cylindrical rod 11 fixed at the bottom of the support rod 10 passes through the assembly groove 8 at the bottom of the first cavity 9, and the outer wall of the cylindrical rod 11 is tightly fitted with the inner wall of the vertical rod 7 fixed at the upper end of the base 6. The vertical rod 7 is threadedly connected to the assembly groove 8. The anti-slip pad at the lower end of the base 6 directly contacts the ground, and the anti-slip texture on the periphery of the base 6 can improve the grip stability during manual operation.

[0045] At this time, the bottom wheel 12 at the lower end of the cylindrical rod 11 is housed in the second cavity 14 inside the base 6 and will not directly bear the weight of the entire device. The first rotating shaft 15 inside the fixed box 5 forms an interference fit rotational connection with the lower end of the fixed box 5 through the first bearing. The second bearing is embedded in the groove 18 at the upper end of the first rotating shaft 15. The limiting block 19 at the lower end of the limiting plate 17 is inserted into the groove 18 and passes through the inner ring of the second bearing. The upper surface of the limiting plate 17 contacts the lower end of the digital twin production line scheduling cabinet 1, providing auxiliary support for the first rotating shaft 15. The driven bevel gear 16 on the first rotating shaft 15 is also located in the opening structure inside the fixed box 5. The threaded rod 13 at the lower end of the first rotating shaft 15 is inserted into the support rod 10 and forms a threaded connection. The entire device is stably stationary through the anti-slip pad of the base 6, and the bottom wheel 12 is effectively protected because it is housed in the second cavity 14.

[0046] Leveling uneven ground:

[0047] When the device needs to be deployed on an uneven production workshop floor, leveling can be achieved using the threaded adjustment structure of the base 6. The operator holds the anti-slip texture on the periphery of the base 6 and rotates the base 6. The base 6 drives the upper vertical rod 7 to rotate threadedly within the assembly groove 8, thereby changing the depth of the vertical rod 7 within the assembly groove 8, and thus adjusting the overall height of the individual support component.

[0048] During this process, the tight fit between the cylindrical rod 11 and the vertical rod 7, the tight fit between the support rod 10 and the first cavity 9, and the rectangular cross-sectional structure of the support rod 10 ensure that the cylindrical rod 11 and the support rod 10 will not wobble or shift during the adjustment process. This ensures that the height adjustment of each support component is accurate and stable, and ultimately enables the digital twin production line scheduling cabinet 1 to remain horizontal on uneven ground, ensuring the stable operation of the scheduling work.

[0049] Portable mobile mode switching:

[0050] When the device needs to be moved to a production line fault location, a temporary expedited order workstation, or other special scenario, the mobile switching procedure can be initiated. First, the control module of motor 27 is controlled by wireless remote control. After motor 27 is started, the drive gear 28 at the output end of motor 27 will drive two symmetrically distributed driven gear 26 to rotate. The driven gear 26 is fixed to the lower end of the third rotating shaft 24. The third rotating shaft 24 is rotatably connected to the housing 20 at the lower end of the digital twin production line scheduling cabinet 1 through the fifth bearing, and the worm gear 25 on the third rotating shaft 24 rotates synchronously.

[0051] The worm 25 meshes with the worm wheel 22 inside the housing 20, thereby driving the second rotating shaft 21 fixed to the worm wheel 22 to rotate. The two ends of the second rotating shaft 21 are respectively connected to the housing 20 through the third bearing and to the fixed housing 5 through the fourth bearing. The drive bevel gears 23 at both ends of the shaft rotate accordingly and mesh with the driven bevel gear 16 inside the fixed housing 5, thereby driving the first rotating shaft 15 to rotate synchronously.

[0052] When the first rotating shaft 15 rotates, the limiting plate 17 and the limiting block 19 at its top are kept in relative rotation by the second bearing, which provides stable support for the first rotating shaft 15 without affecting its rotational transmission. As the first rotating shaft 15 rotates, the threaded rod 13 at its lower end, due to its fixed position, drives the support rod 10 to slide downward along the first cavity 9 through threaded transmission. The cylindrical rod 11 at the bottom of the support rod 10 then descends, thereby pushing the bottom wheel 12 out of the second cavity 14 of the base 6 until the bottom wheel 12 contacts the ground and lifts the base 6, causing the anti-slip pad at the bottom of the base 6 to leave the ground. At this time, the operator can temporarily install a handle on one side of the digital twin production line scheduling cabinet 1, and use the rolling of the bottom wheel 12 to realize the portable movement of the device and complete the cross-regional scheduling transfer.

[0053] Dust environment protection deployment:

[0054] If the device needs to be used in a dusty production workshop environment, in order to ensure the transmission stability of the threaded rod 13, a telescopic protective sleeve can be installed between the upper end of the support rod 10 and the lower end of the fixed box 5. The protective sleeve is penetrated by the threaded rod 13, and its upper and lower ends are respectively connected to the fixed box 5 and the support rod 10. It can effectively prevent dust from entering the threaded mating area between the threaded rod 13 and the support rod 10, and avoid dust accumulation affecting the transmission accuracy.

[0055] The fixed box 5 is precisely assembled using a positioning plate and screws to avoid installation misalignment. The first rotating shaft 15 forms an interference fit with the fixed box 5 through the first bearing. At the same time, the combination structure of the limiting plate 17, the limiting block 19, the second bearing, and the groove 18 not only ensures the flexibility of rotation but also provides auxiliary support to prevent shaking during transmission. The second rotating shaft 21 forms an interference fit with the box 20 through the third bearing, and the fourth bearing forms an interference fit with the fixed box 5. The third rotating shaft 24 forms an interference fit with the box 20 through the fifth bearing, ensuring the overall smoothness of the drive assembly transmission.

[0056] When the base 6 rotates, the threaded connection between the vertical rod 7 and the groove 18 enables precise height adjustment. Combined with the tight fit between the cylindrical rod 11 and the vertical rod 7, the support rod 10 and the first cavity 9, and the rectangular cross-section design of the support rod 10, it can effectively prevent component displacement during adjustment and support. In addition, the anti-slip pad at the bottom of the base 6 ensures stable deployment even on uneven ground, guaranteeing the horizontal position of the dispatch cabinet and the accuracy of dispatching work.

[0057] When stationary, the bottom wheel 12 can be stored in the second cavity 14 of the base 6. At this time, the anti-slip pad of the base 6 directly bears the weight of the device, and the bottom wheel 12 does not need to bear pressure for a long time. At the same time, the base 6 can isolate external dust, water vapor and other corrosive substances, which greatly extends the service life of the bottom wheel 12. In dusty environments, the added telescopic protective sleeve can wrap around the threaded rod 13 to prevent dust from entering the threaded mating surface and causing wear, ensuring the transmission accuracy and service life of the threaded rod 13 and the support rod 10, and reducing the frequency and cost of later maintenance.

[0058] The anti-slip texture on the six sides of the base provides a good grip for manual leveling operations, reducing the difficulty of on-site adjustment; the wireless remote control module equipped with motor 27 can realize convenient remote switching of mobile status without complicated on-site operations; the retractable protective sleeve design allows the device to adapt to complex production environments such as high dust levels, improving the device's adaptability to various working conditions and further expanding its application boundaries in discrete manufacturing scenarios.
