[0025] Please see the appendix Figures 1-4An embodiment of the present invention provides a plate vertical warehouse centering device, comprising a movable support mechanism 10, a lifting mechanism 20, and a clamping mechanism 30. First, it should be noted that in this application, "lateral" refers to the width direction (moving and advancing direction) of the entire device, and "longitudinal" refers to the length direction of the entire device. Please refer to the accompanying drawings for details; the specific design is as follows: The movable support mechanism 10 is movably arranged laterally; the lifting mechanism 20 includes a lifting bracket 210, a lifting assembly 220, and multiple supporting assemblies 230. The bottom end of the lifting assembly 220 is connected to the movable support mechanism 10, and the top end of the lifting assembly 220 is vertically retractable and connected to the lifting bracket 210. The multiple supporting assemblies 230 are spaced apart on the lifting bracket 210, and the top of the supporting assembly 230 is used for placing the steel plate 40; the clamping mechanism 30 The system includes a gantry frame 310, a transmission assembly 320, and a first clamping arm assembly 330 and a second clamping arm assembly 340 arranged longitudinally opposite each other. The two ends of the gantry frame 310 are located on the outer sides of the movable support mechanism 10 along the longitudinal direction. The first clamping arm assembly 330 and the second clamping arm assembly 340 are both connected to the transmission assembly 320. The transmission assembly 320 is connected to the top of the gantry frame 310 to drive the first clamping arm assembly 330 and the second clamping arm assembly 340 to move in opposite directions.

[0026] Specifically, the plate storage and alignment device in this application includes a movable support mechanism 10, a lifting mechanism 20, and a clamping mechanism 30. The movable support mechanism 10 is used for the movement and conveying of the entire device and for the installation and connection of other mechanisms. Its lateral mobility allows the device to flexibly adapt to different storage stations and plate conveying lines, improving its integration compatibility with automated storage and retrieval systems. The lifting mechanism 20 is used for placing and pushing the steel plate 40 for storage, and includes a lifting bracket 210 and a lifting assembly 2. The equipment includes a lifting bracket 210 and multiple supporting components 230. The lifting bracket 210 is used to install the supporting components 230 as a structural load-bearing body. It provides stable support for the steel plate 40 through multiple spaced supporting components 230, avoiding collision damage caused by the steel plate 40 directly contacting the conveying surface. At the same time, the vertical extension and retraction function of the lifting component 220 can realize the conveying and storage of the steel plate 40. The clamping mechanism 30 is used to clamp and center the steel plate 40 during the conveying and storage process, thereby improving the compatibility of the equipment.

[0027] The clamping mechanism 30 includes a gantry frame 310, a transmission assembly 320, and a first clamping arm assembly 330 and a second clamping arm assembly 340 arranged longitudinally opposite each other. The gantry frame 310 is used for the installation and connection of other components. The transmission assembly 320 is used to drive the first clamping arm assembly 330 and the second clamping arm assembly 340 to move. The first clamping arm assembly 330 and the second clamping arm assembly 340, which are arranged symmetrically in both directions, can achieve synchronous opposite / backward movement under the drive of the transmission assembly 320, so as to adapt to steel plates 40 of different widths. During centering, the position of the steel plate 40 can be adjusted left and right according to the entrance of the vertical storage unit by the transmission assembly 320, thereby ensuring that the centering accuracy can be correct for storage. In addition, it can also ensure that the steel plate 40 is subjected to balanced force during the centering process, effectively avoiding the offset caused by unilateral force, and significantly improving the centering accuracy and consistency.

[0028] In a preferred embodiment of the present invention, the lifting assembly 220 includes a worm gear reducer 221 and a nut 222. The worm gear reducer 221 is connected to the movable support mechanism 10. The worm end of the worm gear reducer 221 extends vertically and is threadedly connected to the lifting bracket 210. The nut 222 is connected to the worm of the worm gear reducer 221 and abuts against the lifting bracket 210.

[0029] It should be noted that the worm gear reducer 221 is composed of a worm gear structure and a reducer. It is a commonly used transmission mechanical device with the characteristics of smooth transmission and excellent self-locking performance. It can not only provide uniform and sufficient vertical driving force for the lifting support 210 to ensure the smooth lifting of the steel plate 40, but its self-locking property can also effectively prevent the lifting support 210 from falling unexpectedly when carrying the steel plate 40, thus improving the safety of operation from a structural perspective. The threaded connection and abutment structure between the nut 222 and the worm gear play a dual positioning and locking role. When adjusting the height, the vertical position of the lifting support 210 is controlled by the rotation of the thread.

[0030] In a preferred embodiment of the present invention, each of the top support components 230 includes a top rod 231 and a universal ball bearing 232. The bottom end of the top rod 231 is fixed to the lifting bracket 210, and the universal ball bearing 232 is connected to the top end of the top rod 231.

[0031] It is important to note that the top rod 231 provides stable rigid support for the steel plate 40, ensuring support strength; the universal ball bearing 232 at the top changes the contact mode between the steel plate 40 and the top support assembly 230 from sliding friction to rolling friction, which greatly reduces the movement resistance of the steel plate 40 during the clamping and centering process, allowing the steel plate 40 to adaptively adjust its position according to the force of the clamping arm, thus improving centering efficiency; at the same time, during centering adjustment, rolling contact can effectively avoid scratches and indentations on the surface of the steel plate 40 caused by sliding friction, which is especially suitable for steel plates 40 with high surface precision requirements, protecting the appearance and performance of the plate, and broadening the applicable scenarios of the device.

[0032] In a preferred embodiment of the present invention, a guide rod 240 extending vertically is further included, and a guide hole is provided on the lifting bracket 210 for the guide rod 240 to pass through.

[0033] It is worth noting that the guide rod 240 and the guide hole on the lifting bracket 210 form a precise sliding fit, providing a clear guide trajectory for the vertical movement of the lifting bracket 210, effectively limiting the lateral offset and torsion of the bracket during the lifting process, and ensuring that the multiple support components 230 always maintain synchronous lifting.

[0034] In a preferred embodiment of the present invention, the transmission assembly 320 includes a transmission chain 321, a servo motor 322, and two sprockets 323 arranged longitudinally opposite each other. The two ends of the transmission chain 321 are respectively engaged with the two sprockets 323. The servo motor 322 is connected to the gantry frame 310, and the drive end of the servo motor 322 is connected to one of the sprockets 323. The first clamping arm assembly 330 is connected to the lower chain at the first end of the transmission chain 321, and the second clamping arm assembly 340 is connected to the upper chain at the second end of the transmission chain 321.

[0035] It is worth noting that the servo motor 322 has precise speed and position control capabilities, and can adjust the transmission speed and stroke in real time according to the width of the steel plate 40 to adapt to the centering requirements of different specifications of plates. The cooperative design of the double sprocket 323 and the transmission chain 321 allows the first and second clamping arm assemblies 340 to be connected to the upper and lower sides of the chain respectively, realizing the synchronous reverse movement of the two clamping arms. This ensures that the clamping force on both sides is balanced and the movement trajectory is symmetrical during the centering process, avoiding the deviation or tilting of the steel plate 40 due to uneven force on one side. The chain drive structure is reliable, has high transmission efficiency, and low maintenance costs. It can operate stably for a long time, improving the continuity of automated operation and centering accuracy of the device, and meeting the high-efficiency operation requirements of the intelligent warehousing system.

[0036] Further, the first clamping arm assembly 330 includes a first folding arm 331, a first connecting seat 332, and a first clamping roller 333; the second clamping arm assembly 340 includes a second folding arm 341, a second connecting seat 342, and a second clamping roller 343; wherein, one end of the first folding arm 331 is connected to the lower chain of the first end of the transmission chain 321 through the first connecting seat 332, and the first clamping roller 333 is connected to the other end of the first folding arm 331; one end of the second folding arm 341 is connected to the upper chain of the second end of the transmission chain 321 through the second connecting seat 342, and the second clamping roller 343 is connected to the other end of the second folding arm 341.

[0037] It should be noted that, compared to the straight arm structure, the folding arm design, while ensuring clamping rigidity, effectively optimizes the installation space, allowing the clamping arm assembly to adapt to the structural layout of the gantry 310 and avoid interference with other mechanisms. For example, the bottom side of one end connected to the transmission chain 321 can be placed on the gantry 310, allowing the gantry 310 to play an auxiliary support role and improve the stability of the folding arm transmission. The other end adopts a form of horizontal extension followed by vertical downward suspension to adapt to the clamping position of the steel plate 40. The rolling contact method between the clamping rollers and the steel plate 40 reduces wear and damage to the plate surface during alignment, ensuring the fit between the clamping arm and the steel plate 40 and improving alignment accuracy. The connecting seat achieves a stable connection between the clamping arm and the transmission chain 321, ensuring the reliability of power transmission. The overall structure is compact and the force is reasonable, further enhancing the alignment stability and practicality of the device.

[0038] Furthermore, the clamping mechanism 30 also includes a guide rail 350 and a longitudinal slider 360. The guide rail 350 is connected to the gantry frame 310, and the longitudinal slider 360 is connected to one side of the second folding arm 341. The longitudinal slider 360 is slidably connected to the guide rail 350 along the longitudinal direction.

[0039] It should be understood that the sliding connection between the longitudinal slider 360 and the guide rail 350 provides precise guidance for the longitudinal movement of the second clamping arm assembly 340, ensuring that the movement trajectories of the first and second clamping arm assemblies 340 remain parallel, and avoiding centering deviation caused by movement offset of the clamping arm; at the same time, the cooperation between the guide rail 350 and the slider can also share the lateral force of the clamping arm assembly, protect the connection structure between the transmission chain 321 and the clamping arm, extend the service life of the mechanism, and further ensure the consistency of centering accuracy.

[0040] Furthermore, the lifting bracket 210 is a rectangular bracket, and each corner of the lifting bracket 210 is provided with a lifting component 220 and a guide rod 240.

[0041] It should be noted that the rectangular support structure is symmetrical and evenly stressed, providing comprehensive and stable support for steel plates 40 of different sizes, avoiding bending and deformation of the steel plates 40 due to excessive local stress; the lifting components 220 distributed at the four corners ensure balanced force during the lifting and lowering of the support, keeping the support level and preventing tilting; the corresponding guide rods 240 further enhance the balanced guiding effect at each corner, preventing the support from twisting or shifting during lifting and lowering, ensuring that multiple support components 230 operate synchronously, providing a stable and uniform support foundation for the steel plates 40, improving the device's adaptability to large-sized, heavy-duty steel plates 40, and enhancing the overall stability and reliability of the structure.

[0042] Furthermore, the mobile support mechanism 10 includes a slide rail 110 and an RGV platform vehicle 120. The slide rail 110 extends laterally, and the RGV platform vehicle 120 is slidably connected to the slide rail 110 laterally. The worm gear reducer 221 is connected to the RGV platform vehicle 120.

[0043] It is worth noting that the RGV platform cart 120 features automated control and precise movement. It can automatically adjust its lateral position along the slide rail 110, adapting to different warehousing stations, sheet material conveying lines, or automated warehouse layouts without manual intervention, significantly improving operational efficiency and automation integration capabilities. The slide rail 110 provides a precise guide trajectory for the RGV platform cart 120, ensuring smooth movement and accurate positioning, and preventing subsequent lifting and centering operations from being affected by platform cart deviation. The overall structure is reliable and easy to move, enabling the device to quickly respond to different warehousing needs, broadening the application scenarios of the device, and meeting the flexible production requirements of modern intelligent warehousing systems.

[0044] Furthermore, the plurality of the top support components 230 are arranged in a matrix.

[0045] Understandably, the matrix-arranged top support components 230 can provide multi-point uniform support for the steel plate 40, avoiding excessive local stress and bending deformation caused by uneven distribution of support points. This is especially suitable for supporting thin or large-sized steel plates 40. The uniformly distributed support points ensure that the steel plate 40 remains horizontal during the alignment process, with balanced force, thus improving alignment accuracy. At the same time, the matrix arrangement design allows for flexible adjustment of the number of top support components 230 in use according to the size of the steel plate 40, adapting to plates of different lengths and widths, further enhancing the versatility of the device. This enables the device to meet diverse warehousing alignment needs, improving the practicality and economy of the equipment.

[0046] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural or procedural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
