Description

Technical Field

[0001] The present invention relates to the technical field of weighing equipment, and in particular to a weighing detection platform suitable for intelligent three-dimensional warehousing. Background Art

[0002] With the rapid development of intelligent warehousing technology, automated and intelligent warehousing equipment has become an indispensable component of modern logistics systems. In intelligent three-dimensional warehousing systems, weighing and detection are key links in the process of goods entering, exiting, and inventorying. Its accuracy and efficiency directly affect the operational quality of the entire warehousing system.

[0003] Currently, common intelligent warehouse weighing devices on the market primarily fall into two categories: fixed weighing platforms and mobile weighing devices. For example, CN114858257B discloses an intelligent inventory counting vehicle, which includes a mobile platform, wheels, a weighing platform, a scanner, a lifting assembly, and a hanging card assembly. This vehicle can count items in a variety of spaces, improving spatial adaptability.

[0004] However, the existing intelligent warehouse weighing and detection equipment still has the following technical problems:

[0005] During mechanized operations, when robots or automated equipment place items on the weighing platform, improperly controlled force often causes impact damage to the pressure sensors within the weighing platform, reducing their service life and measurement accuracy. This damage can accumulate, especially in high-frequency smart warehousing environments, ultimately requiring frequent repair or replacement of the equipment.

[0006] When an item is not positioned centrally on existing weighing platforms (due to variations in the item's conveying position or the gripping position of the robot), the pressure sensor experiences uneven force, leading to deviations in the weighing readings. This deviation is particularly pronounced when handling irregularly shaped items or when the robot's positioning accuracy is insufficient, severely impacting weighing accuracy.

[0007] For items requiring high-precision weighing or with delicate surfaces, existing weighing platforms with clamping mechanisms have difficulty controlling the clamping force, which can easily damage the surface of the items. Furthermore, the complexity of the clamping mechanism increases equipment failure rates and maintenance costs.

[0008] Therefore, there is an urgent need for an intelligent three-dimensional warehouse weighing and testing platform that can effectively solve the above problems, which can not only protect the pressure sensor from impact damage, but also ensure that the items are in the center position during the weighing process, and can safely handle various items without causing damage.

DETAILED DESCRIPTION

[0035] In order to better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

The term "two or more" includes two or more than two cases.

[0037] See also Figures 1 to 10As shown, the embodiment of the present application provides a weighing and testing platform suitable for intelligent three-dimensional storage, including a weighing platform 10, a pressure sensor is provided in the weighing platform 10, and further comprising: a support platform 30 and a bearing platform 40, the support platform 30 is arranged on the top of the weighing platform 10 and can be lifted and moved; the bearing platform 40 is used to carry the measured object 100, and the bearing platform 40 can be arranged on the support platform 30 to tilt to any side, and a plurality of centering components 41 arranged horizontally in the circumferential direction are provided on the bearing platform 40, and the centering components 41 are in contact with the object 100. The centering component 41 is used to realize the centering movement of the surface of the carrier platform 40 for the object 100 before the object 100 is measured; wherein, the carrier platform 40 is also provided with a plurality of transmission components 42 that pass through the support platform 30, and the bottom end of the transmission component 42 is provided with a power input end, and the top end of the transmission component 42 is a power output end, and the power output end of the transmission component 42 is connected to the centering component 41; when the weighing object 100 is not centered, the carrier platform 40 is in a tilted state, and the power input end of the transmission component 42 on the tilted side is connected to the power.

[0038] The intelligent three-dimensional storage weighing and testing platform provided in this embodiment effectively solves the problems existing in the prior art such as the misplacement of the article 100, the damage of the pressure sensor by impact, and the difficulty in weighing high-precision articles 100 through innovative design. The weighing platform 10 includes a tiltable supporting platform 40, a centering component 41, and a multi-point contact automatic adjustment mechanism. When the article 100 is not placed in the center, the supporting platform 40 triggers the centering component 41 through the transmission component 42 to automatically move the article 100 to the center, ensuring that the pressure sensor is evenly stressed and avoiding errors. The lifting and elastic buffering mechanism of the support platform 30 effectively reduces the impact force generated when the robot or automated equipment places the article 100, protects the pressure sensor, extends its service life, and maintains weighing accuracy. In addition, the designed low-damage clamping function and automatic centering positioning mechanism can effectively adapt to various articles 100 in the intelligent three-dimensional storage environment, especially articles 100 with irregular shapes or uneven weights, improve weighing accuracy, reduce equipment maintenance costs, and enhance the protection capability of the articles 100. It is particularly suitable for intelligent storage systems with high precision requirements.

[0039] It should be noted that the transmission component 42 is movable through the support platform 30 through the through hole opened on the support platform 30. In order to realize the tilting movement of the support platform 40 in multiple directions, it should be noted that there is sufficient movement margin gap between the through hole and any side wall of the transmission component 42 to prevent the transmission component 42 from interfering with the support platform 30 when it tilts with the support platform 40.

[0040] like Figures 2 to 5As shown, in some examples, further, the support platform 30 is provided with: a spherical seat 31, a plurality of elastic support components 32, a plurality of guide columns 33 and a spring 37. The spherical seat 31 is arranged between the support platform 30 and the bearing platform 40, and adopts a damping structure arrangement, so that after the article is placed on the bearing platform, it will not tilt instantly, and the bearing platform 40 can be rotated and tilted to any side through the spherical seat 31; a plurality of elastic support components 32 are equidistantly arranged at the top of the support platform 30, and the top of the elastic support component 32 is arranged at the bottom end edge of the bearing platform 40; a plurality of guide columns 33 are equidistantly arranged at the support platform The bottom end of the platform 30 can be movably inserted into the weighing platform 10; the spring 37 is fixedly arranged in the weighing platform 10, and the spring 37 is used to realize the reset of the support platform 30. The elastic force of the spring 37 is optimized. When no items are placed on the load-bearing platform, the elastic thrust of the spring 37 is slightly greater than the thrust when pushing the entire support platform up and reset, so that the spring is just, or slightly greater than, the elastic thrust required for reset. Under the action of the weight of the item, the overall weight of the support platform 30 increases suddenly, and the item and the overall support platform can overcome the reset elastic force and move down an appropriate distance to drive the ball screw nut 35 to rotate.

[0041] In this embodiment, the support platform 30 ensures the tilting and resetting functions of the support platform 40. Specifically, the support platform 30 is provided with a spherical seat 31, multiple elastic support assemblies 32, multiple guide posts 33, and a spring 37. The spherical seat 31 is installed between the support platform 30 and the support platform 40. The support platform 40 can rotate and tilt in any direction through the spherical seat 31, thereby generating a low end on one side. This helps to automatically center the object 100 and ensure that the object 100 is always positioned optimally during the weighing process. Multiple elastic support assemblies 32 are equidistantly arranged at the top of the support platform 30, providing uniform support force and a certain degree of cushioning during the placement of the object 100, protecting the pressure sensor from damage. The support platform 30 also automatically resets itself after the object 100 is centered, releasing the power input of the transmission assembly 42. After the object 100 is weighed, the elastic support assemblies 32 help the support platform 40 to return to its overall horizontal position. In addition, a plurality of guide posts 33 are provided at the bottom end of the support platform 30. The guide posts 33 can be movably inserted into the inside of the weighing platform 10 to ensure the stability of the support platform 30 in the vertical direction and prevent the support platform 30 from rotating during the lifting process. A spring 37 is fixedly arranged inside the weighing platform 10. The spring 37 provides a reset force to ensure that the support platform 30 can quickly return to its original position after completing the weighing work of tilting and centering the object 100, preparing for the next weighing work of the object 100. Therefore, the setting of this example effectively improves the stability, accuracy and durability of the equipment, and can continue to work stably in a high-frequency automated operation environment.

[0042] like Figure 4As shown, in some examples, further, a vertical screw column 12 is provided inside the weighing platform 10, and the support platform 30 is further provided with: a rotating sleeve 34, a ball screw nut 35, an abutment disc 36 and a driving wheel 38. The rotating sleeve 34 is rotatably provided at the bottom end of the support platform 30 through a bearing seat to reduce the rotational friction between the rotating sleeve 34 and the bottom end of the support platform 30. It is sleeved on the outside of the screw column 12; the ball screw nut 35 is rotatably sleeved on the outer wall of the screw column 12, and the top end of the ball screw nut 35 is fixedly connected to the bottom end of the rotating sleeve 34; the abutment disc 36 is provided on the outer wall of the rotating sleeve 34, and the top end of the spring 37 abuts the bottom end of the abutment disc 36; the driving wheel 38 is fixedly sleeved on the outer wall of the rotating sleeve 34; and the driving wheel 38 can be transmission-connected to the power output end of any transmission component 42.

[0043] In this embodiment, after an object 100 is placed on the support platform 40, its weight causes the support platform 30 to compress downward, triggering the entire adjustment mechanism. Specifically, as the support platform 30 is compressed, the ball screw nut 35 moves downward along the guide of the screw column 12. This downward movement of the ball screw nut 35 is converted into its own rotational motion. This rotational motion is transmitted through the rotating sleeve 34, which drives the drive wheel 38, which is fixedly connected to the rotating sleeve 34, to rotate. During the downward movement of the object 100, if the object 100 is not centered on the support platform 40, the support platform 40 will tilt accordingly. At this time, the power input end of the transmission assembly 42 on the tilted side is driven by the rotation of the drive wheel 38, which in turn drives the transmission assembly 42 on that side to rotate, driving the centering assembly 41 to move the object 100 from the offset position to the center of the support platform 40. Through this adjustment process, even if the object 100 is not initially centered, the system can automatically center the object 100, thereby ensuring uniform force on the pressure sensor and ensuring weighing accuracy. The entire process realizes the automated centering adjustment and precise weighing of the object 100 through the coordinated work of the screw column 12, the ball screw nut 35, the rotating sleeve 34, the driving wheel 38 and the transmission assembly 42.

[0044] like Figure 4 、 Figure 6 and Figure 7As shown, in some examples, further, the centering component 41 includes: multiple centering belts 411, multiple driving bars 412, multiple slide grooves 413 and contact blocks 414, the centering belt 411 can be rotatably set in the inner wall of the support platform 40; multiple driving bars 412 are equidistantly fixed and opened in the middle position of the outer wall of the centering belt 411, and the output end of the transmission component 42 can be engaged and connected to the driving bar 412; multiple slide grooves 413 are equidistantly opened at the edge position of the outer wall of the centering belt 411, and are located on both sides of the driving bar 412; the contact block 414 can be slidably set in each slide groove 413, and the outer outer wall of the contact block 414 is in a planar state. The contact block 414 is used to provide multi-point centripetal displacement extrusion motion compensation of the object 100 when the object 100 moves in the center.

[0045] In this embodiment, the centering component 41 is further optimized to improve the accuracy and efficiency of the centering adjustment of the article 100. The centering component 41 includes a plurality of centering belts 411, a plurality of drive bars 412, a plurality of slide grooves 413 and a contact block 414. The centering belt 411 is arranged in the inner wall of the carrier 40 and can rotate freely, playing a core role in the centering adjustment of the article 100. A plurality of drive bars 412 are fixed at equal distances in the middle position of the outer wall of the centering belt 411. Through the setting of the drive bars 412, the output end of the transmission component 42 can engage with the drive bars and drive the centering belt 411 to rotate, thereby realizing the automatic centripetal movement of the article 100. A plurality of slide grooves 413 are equidistantly opened at the edge position of the outer wall of the centering belt 411, and the positions of the slide grooves 413 are opposite to the two sides of the drive bars 412. The contact block 414 can slide freely in each slide groove 413, and its outer wall is in a flat state. The design of the contact block 414 enables the contact block 414 to apply a multi-point centripetal displacement force to the object 100 through the slide groove 413 when the object 100 is not centered, thereby achieving extrusion motion compensation during the centering process of the object 100.

[0046] Specifically, given that the conveying directions of the centering belts 411 are typically non-parallel, when an item 100 is driven simultaneously by multiple centering belts 411, it may deviate due to the different directions of the two conveyor belts, potentially causing damage to the item 100. To address this issue, the present technical solution features an additional, flexible contact block 414. The contact block 414 slides freely through the chute 413. During the centering process, the contact block 414 can flexibly adjust its position based on the force direction and displacement trajectory of the item 100, thereby preventing the item 100 from being affected by directional deviations caused by multiple conveyor belts. The design of the contact block 414 not only provides uniform force distribution, helping the item 100 to move smoothly toward the center, but also, through its flexible displacement function, allows for appropriate adjustments when the item 100 deviates from the center, ensuring that the item 100 is not subjected to excessive pressure or damage due to different conveyor belt directions. This design effectively improves the item 100's ability to adapt to various external forces during movement and reduces damage to the item 100 caused by non-parallel conveyor belts.

[0047] like Figure 4 、 Figure 7 and Figure 9 As shown, in some examples, further, the transmission assembly 42 includes: a driven wheel 421, a rotating shaft 422 and a transmission box 424, the driven wheel 421 can be movably arranged at the bottom end of the transmission assembly 42; the driven wheel 421 can rotate around the center of the spherical seat 31 and engage with the driving wheel 38; the rotating shaft 422 passes through the driven wheel 421, and the middle part of the rotating shaft 422 is fixed to the bottom end of the transmission assembly 42 by at least one shaft seat; one end of the rotating shaft 422 is set as a universal shaft end 423; the transmission box 424 includes a power output shaft, which is connected to the universal shaft end 423 of the rotating shaft 422 through a universal coupling, and the transmission box 424 also includes an output end, and an output wheel 4241 is provided on the output end of the transmission box 424, and the output wheel 4241 is transmission-engaged on the driving bar 412 of the center belt 411.

[0048] This embodiment achieves efficient coordination of driving and transmission functions. Specifically, the transmission assembly 42 includes a driven wheel 421, a rotating shaft 422 and a transmission box 424, wherein the driven wheel 421 can be rotatably arranged at the bottom end of the transmission assembly 42, and the driven wheel 421 can freely rotate around the center of the spherical seat 31 and engage with the driving wheel 38 to realize the transmission of power to the transmission box 424. The rotating shaft 422 runs through the driven wheel 421, and the middle part of the rotating shaft 422 is fixed to the bottom end of the transmission assembly 42 by at least one shaft seat to ensure that the rotating shaft 422 rotates stably during operation. One end of the rotating shaft 422 is set as a universal shaft end 423, which is connected to the universal coupling. The transmission box 424 includes a power output shaft, which is connected to the universal shaft end 423 of the rotating shaft 422 through a universal coupling and can transmit rotational power. Another important component of the transmission box 424 is its output end, on which an output wheel 4241 is provided. The output wheel 4241 engages with the driving bar 412 of the centering belt 411 through mechanical transmission, driving the centering belt 411 to rotate, thereby realizing automatic centering adjustment of the object 100.

[0049] like Figure 7 and Figure 8 As shown, in some examples, further, a plurality of reset drive blocks 425 are provided on the transmission assembly 42, and the plurality of reset drive blocks 425 are arranged gradually from the middle to the edge, wherein the first group of reset drive blocks 425 contacted after the center belt 411 rotates into the top of the transmission assembly have the smallest spacing, and the last group of reset drive blocks 425 have the largest spacing; a plurality of magnetic blocks are also provided inside the contact block 414, and the magnetic blocks inside the contact block 414 can interact with the reset drive block 425.

[0050] In this embodiment, a magnetic mechanism is designed to reposition the contact blocks 414, employing multiple reset drive blocks 425 and contact blocks 414, to address the potential for the contact blocks 414 to become dislocated after the object 100 is transported. Since the centering belt 411 operates continuously during operation, the contact blocks 414 may be displaced from their initial positions due to the movement of the object 100 or external forces. To address this issue, this technical solution utilizes multiple magnetic blocks positioned within the contact blocks 414 to interact with the reset drive blocks 425, achieving the reset function for the contact blocks 414. These multiple magnetic blocks, through repulsion or magnetic attraction, precisely restore the contact blocks 414 from their non-operating positions to their predetermined, pre-operation edge positions. This reset process is achieved by gradually pushing the magnetic blocks at different locations, ensuring that each contact block 414 automatically adjusts to its correct starting position after transporting, based on the magnetic field force. This smooth reset of the contact blocks 414 ensures that all contact blocks 414 are in their correct operating state the next time the object 100 is centered. And continue to provide a centered adjustment movement effect with low damage to items 100.

[0051] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 10 As shown, in some examples, further, the elastic support assembly 32 includes: a support rod 321, a fixed seat 322 and a slider 323, the bottom end of the support rod 321 is connected to the top of the support platform 30 through a universal connection seat; the fixed seat 322 is fixedly set on the bottom outer wall of the supporting platform 40; the slider 323 is slidably set in the inner cavity of the fixed seat 322, and spring clips are provided at both ends of the sliding direction of the slider 323, and the bottom end of the slider 323 is movably connected to the top of the support rod 321 through the universal connection seat.

[0052] In this embodiment, the elastic support assembly 32 enhances the stability and flexibility of the support platform 40 through the coordinated arrangement of the support rod 321, the fixed seat 322 and the slider 323. Specifically, the bottom end of the support rod 321 is connected to the top end of the support platform 30 through a universal connecting seat. After the item 100 is placed, the support rod 321 is allowed to rotate flexibly in multiple directions, ensuring that the support platform 30 can adapt to various load changes when carrying the item 100. The fixed seat 322 is fixedly set on the outer wall of the bottom end of the support platform 40 to provide a stable support point. The slider 323 is designed to be able to slide freely in the inner cavity of the fixed seat 322, and springs are provided at both ends of the sliding direction of the slider 323. The springs provide elastic reaction force during the sliding process of the slider 323, play a role of buffering and adjustment, and reduce the impact force generated on the support platform 40 when the item 100 is placed or transported.

[0053] When the object 100 is placed or moved, the design of the elastic support assembly 32 effectively disperses external impact forces and maintains the stable operation of the load platform 40, preventing damage to the equipment or unstable weighing results caused by excessive impact forces. Furthermore, after the object 100 is weighed, the entire load platform 40 automatically returns to a horizontal state, ready for the next weighing operation.

[0054] like Figures 1 to 4 As shown, in some examples, further, a base 20 is provided under the weighing platform 10, and at least two rollers and a steering wheel are provided on the base 20, and the rollers and the steering wheel are both connected to a self-drive control device; an enclosing baffle 11 is provided on the outside of the pressure sensor.

[0055] In this embodiment, in order to enhance the mobility of the weighing platform 10 and achieve a more intelligent mobile transportation effect, a base 20 is provided under the weighing platform 10, and is equipped with at least two rollers and a steering wheel. The rollers and the steering wheel are both connected to a self-driving control device, so that the weighing platform 10 can be flexibly moved as needed in a storage or working environment, and the direction and speed of movement can be accurately controlled. The self-driving control device can adjust the rollers and the steering wheel through an electric drive or other control system to ensure that the weighing platform 10 can be efficiently transferred between different working positions. In addition, an enclosed baffle 11 is provided on the outside of the pressure sensor. This design is used to protect the sensor from external physical impact and contamination, and to avoid damage to the sensor or inaccurate measurement due to external interference during the weighing process.

[0056] By applying the technical solution of this example, the device can operate in a movable body state. After the item 100 is placed on the load-bearing platform 40, the overall support platform 30 begins to move downward under the action of the gravity of the item 100. At this time, the ball screw nut 35 converts the linear downward motion of the support platform 30 into a rotational motion. At the same time, the spring 37 sleeved on the outside of the screw column 12 is compressed. When the item 100 is adjusted to the center position by the centering component 41, the overall device will move to the designated position in the warehouse. During this process, the item 100 is removed. At this time, the compressed spring 37 pushes the ball screw nut 35 upward, and the support platform 30 returns to its original high position. Then, the overall device moves to the discharge position again, and after reaching the discharge position, the support platform 30 returns to the high position, ready to accept the next placement and weighing of the item 100.

[0057] like Figure 1 As shown, in some examples, further, a display screen 50 is provided on the front side of the weighing platform 10 , and the display screen 50 is used to display data output from the pressure sensor.

[0058] In this embodiment, a display screen 50 is provided on the front of the weighing platform 10, allowing the operator to view weighing data in real time. The processor is connected to the pressure sensor within the weighing platform 10 and the display screen 50. The pressure sensor of the weighing platform 10 is typically a strain gauge sensor (such as a resistance strain gauge). When an object is applied to the weighing platform, pressure is transmitted to the sensor, causing a slight deformation of the elastic body within the sensor. This change in resistance in the strain gauge generates a weak voltage signal. This voltage signal is amplified by an amplification circuit (such as an instrumentation amplifier) ​​and then converted to a digital signal by an analog-to-digital converter (ADC). A microcontroller (MCU) then processes the digital signal, converting it into weight data based on sensor calibration parameters. This data is then displayed to the user via the display screen 50 by a driver circuit (such as an LCD or LED driver chip), allowing the operator to intuitively view the weight of the object 100. This provides a better operating experience, ensures the real-time and accuracy of weighing data, and enhances the system's intelligence and efficiency.

[0059] The above are merely embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
