Description

Technical Field

[0001] This application relates to the field of logistics and warehousing technology, specifically to a logistics platform and storage method that facilitates the storage of finished goods. Background Technology

[0002] Finished goods warehousing refers to the centralized storage, safekeeping, allocation of storage locations, and inbound / outbound management of finished goods that have completed production and are awaiting sale or transfer. It is a crucial logistics node connecting production and sales. Rational allocation of storage locations is key to ensuring efficient utilization of warehouse space.

[0003] In traditional technologies, the allocation of storage locations for finished goods relies primarily on manual judgment or simple fixed zoning rules. Operators typically select storage locations based on their experience, visually assessing the size and shape of items, or their work habits. For example, they might place large items in large compartments and small items in small compartments simply by visual inspection. However, due to a lack of size comparison, small items often end up occupying large compartments, resulting in wasted storage space. Furthermore, some warehouses use fixed zoning rules, pre-dividing storage areas into several compartments or zones of fixed sizes and assigning specific items to designated areas. However, this static zoning method is difficult to adapt to the diversity of item sizes and batch changes, easily leading to a mismatch between compartment allocation and actual needs, thereby reducing the utilization rate of storage space.

[0004] Therefore, the aforementioned manual judgment and fixed zoning methods can easily lead to the phenomenon of "small items stored in large storage locations," resulting in low utilization of warehouse space. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this application. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0034] Example 1:

[0035] See Figure 1 and 4 A logistics platform for facilitating the storage of finished goods includes a conveyor belt 1, and further includes:

[0036] Storage cabinet 2 is located at one end of the length of conveyor belt 1 and is spaced apart from conveyor belt 1, and has several storage positions 3 of different specifications inside;

[0037] The detection camera 4 is suspended above the conveyor belt 1 along the conveying direction of the conveyor belt 1, and its optical axis intersects the bearing surface of the conveyor belt 1 to collect visual image information of objects on the conveyor belt 1.

[0038] An electrically driven gantry 5 is mounted above the conveyor belt 1 and is movable along the length of the conveyor belt 1. An electric suction cup 6 is movably mounted on the side of the gantry facing the conveyor belt 1 to drive the electric suction cup 6 to reciprocate along the length of the conveyor belt 1.

[0039] Specifically, conveyor belt 1 is used to carry and transport finished products, and its length direction is the product transport direction. Conveyor belt 1 is a conventional belt conveyor. The distance between storage cabinet 2 and conveyor belt 1 forms the moving space for the electrically driven gantry 5 to transfer products between conveyor belt 1 and storage cabinet 2. Multiple storage positions 3 are arranged in an array within storage cabinet 2. The different storage positions 3 have different accommodating sizes to accommodate finished products of different shapes and sizes. Storage positions 3 are recessed accommodating spaces within storage cabinet 2, where products can be placed for storage.

[0040] The inspection camera 4 is suspended above the conveyor belt 1, with its optical axis intersecting the bearing surface of the conveyor belt 1, and is used to collect visual image information of objects on the conveyor belt 1. A certain distance is maintained between the inspection camera 4 and the bearing surface of the conveyor belt 1 so that its field of view can cover the objects to be stored passing on the conveyor belt 1. The inspection camera 4 can be an industrial camera or a machine vision camera, and is fixed above the conveyor belt 1 by an L-shaped bracket 29. The L-shaped bracket 29 can be fixed to one side of the width of the conveyor belt 1 without affecting the conveyor belt 1's transport of objects.

[0041] An electrically driven gantry frame 5 is mounted above the conveyor belt 1 and is movable along the length of the conveyor belt 1, allowing it to reciprocate between the gantry frame 5 and the storage cabinet 2 above the conveyor belt 1. The electrically driven gantry frame 5 includes a crossbeam and two legs 8, located on opposite sides of the width of the conveyor belt 1. The crossbeam connects the two legs 8, forming a gantry structure above the conveyor belt 1. The electrically driven gantry frame 5 has a drive mechanism, enabling movement along the length of the conveyor belt 1 without manual pushing.

[0042] The electric suction cup 6 can move along the length of the conveyor belt 1 with the electric gantry 5 and can move relative to the electric gantry 5, such as lifting and rotating, to approach and pick up objects on the conveyor belt 1. The electric suction cup 6 is preferably a vacuum suction cup, which picks up and releases objects by adsorbing them onto the surface of the objects through negative pressure.

[0043] During operation, finished objects are transported by conveyor belt 1 to the corresponding position of inspection camera 4. Inspection camera 4 captures images of the objects. Electric gantry 5 drives electric suction cup 6 to move to the object on conveyor belt 1. Electric suction cup 6 picks up the object. Then, electric gantry 5 moves to storage cabinet 2 and places the object into storage space 3 that matches the size of the object, thus completing the storage of the object.

[0044] In traditional technologies, the allocation of storage locations for finished goods mainly relies on manual judgment or simple fixed zoning rules. However, manual judgment and fixed zoning methods easily lead to the phenomenon of "small items stored in large storage locations," resulting in low utilization of storage space. This application uses a detection camera 4 to collect visual image information of the items on the conveyor belt 1, and obtains the size information of the items based on the image information. Then, based on the size information, it determines the target storage location 3 that matches the item from the storage locations 3 of different specifications in the storage cabinet 2. The electric gantry 5 drives the electric suction cup 6 to move the item to the storage location 3, thereby establishing a correspondence between the item size and the specifications of the storage location 3 based on actual measurement data. This avoids the unreasonable space utilization phenomenon of storing small items in large storage locations and improves the utilization rate of storage space.

[0045] Example 2:

[0046] See Figure 1 and 2 Based on Embodiment 1, optionally, electric guide rails 7 are provided on both sides of the width of the conveyor belt 1. Both electric guide rails 7 are parallel to the length direction of the conveyor belt 1, and the electric guide rails 7 extend along the length direction of the conveyor belt 1 and terminate at the end of the storage cabinet 2 facing the conveyor belt 1, so as to form a continuous guide path between the conveyor belt 1 and the storage cabinet 2.

[0047] Specifically, the electric guide rails 7 are fixed to the ground, and two electric guide rails 7 form a continuous guide path between the conveyor belt 1 and the storage cabinet 2, allowing the electrically driven gantry 5 to reciprocate between the conveyor belt 1 and the storage cabinet 2 along this guide path. The end of the electric guide rail 7 near the storage cabinet 2 terminates at the end of the storage cabinet 2 facing the conveyor belt 1, enabling the electrically driven gantry 5 to move to the position corresponding to the storage position 3. The spacing between the two electric guide rails 7 is adapted to the span of the electrically driven gantry 5. When the electrically driven gantry 5 spans the conveyor belt 1, its two sides correspond to the two electric guide rails 7 respectively, thus enabling it to move along the electric guide rails 7.

[0048] Optionally, the span of the electric gantry 5 is matched with the distance between the two electric guide rails 7, and electric wheels 9 are installed on the two legs 8 of the electric gantry 5 facing the electric guide rails 7, and the electric wheels 9 are rotatably connected to the electric guide rails 7.

[0049] Specifically, the electrically driven gantry 5 has two legs 8, each located on one of two electric guide rails 7, with each leg 8 having one end facing an electric guide rail 7. An electric wheel 9 is mounted on the end of each leg 8 facing an electric guide rail 7. The electric wheel 9 can employ a hub motor structure (the aforementioned drive device), which drives the wheel to rotate when energized. The outer circumferential surface of the electric wheel 9 makes rolling contact with the guide groove of the electric guide rail 7. When the electric wheel 9 rotates, the wheel rolls along the guide groove of the electric guide rail 7, thereby driving the corresponding leg 8 to move along the length of the electric guide rail 7, and thus causing the entire electrically driven gantry 5 to move along the length of the conveyor belt 1.

[0050] The electric wheels 9 on the two support legs 8 can rotate synchronously to ensure that the electric gantry 5 moves smoothly on the two electric guide rails 7. The guide grooves of the electric guide rails 7 extend along the length of the conveyor belt 1, so that the electric wheels 9 can roll continuously along the electric guide rails 7, realizing the reciprocating movement of the electric gantry 5 between the conveyor belt 1 and the storage cabinet 2.

[0051] During operation, the object to be stored moves along conveyor belt 1 to the acquisition area of ​​detection camera 4, where the camera acquires visual image information of the object. Subsequently, electric wheel 9 rotates and rolls along electric guide rail 7, driving electric gantry 5 to move along the length of electric guide rail 7 to the object on conveyor belt 1. Electric suction cup 6 moves relative to electric gantry 5 and suctions the object. Electric wheel 9 continues to roll along electric guide rail 7 towards storage cabinet 2, causing electric gantry 5 to move synchronously with electric suction cup 6 and the suctioned object. Since electric guide rail 7 extends to the end of storage cabinet 2 facing conveyor belt 1, electric gantry 5 can move from above conveyor belt 1 to the position corresponding to the target storage location 3. At this time, electric suction cup 6 releases the object, allowing it to enter the target storage location 3. Afterwards, electric wheel 9 rolls in the opposite direction along electric guide rail 7, and electric gantry 5 returns to conveyor belt 1, awaiting the next object transfer.

[0052] Example 3:

[0053] See Figure 1 and 2 Based on the above embodiments, optionally, a first mounting groove 10 and a second mounting groove 11 are respectively provided on the side walls of the two legs 8 of the electric gantry frame 5 facing each other along their respective height directions. A first lead screw 12 is rotatably installed in the first mounting groove 10. The end of the first lead screw 12 away from the electric wheel 9 extends out of the first mounting groove 10 and is connected to a first motor 13. The first lead screw 12 is connected to a first slider 14 through a lead screw nut pair, and the first slider 14 is in sliding engagement with the first mounting groove 10.

[0054] A guide rod 15 is installed in the second mounting groove 11, and a second slider 16 is slidably mounted on the guide rod 15. The first slider 14 extends out of the first mounting groove 10 on one side facing the second slider 16, and the second slider 16 extends out of the second mounting groove 11 on one side facing the first slider 14. A mounting plate 17 is provided between the first slider 14 and the second slider 16, and the length direction of the mounting plate 17 is parallel to the width direction of the conveyor belt 1.

[0055] Specifically, bearing seats are fixed at both ends of the first mounting groove 10. The first lead screw 12 is rotatably supported in the bearing seats through the bearings, allowing the first lead screw 12 to rotate around its own axis within the first mounting groove 10. One end of the first lead screw 12 extending out of the first mounting groove 10 can be connected to the output shaft of the first motor 13 via a coupling, or it can be directly fixedly connected. The housing of the first motor 13 is fixed to the frame of the electric drive gantry 5. A lead screw nut is fixedly embedded in the first slider 14, forming a lead screw nut pair with the first lead screw 12. The two sides of the first slider 14 slide in contact with the groove wall of the first mounting groove 10 to restrict the rotation of the first slider 14 with the lead screw, while providing linear guidance for the first slider 14 along the height direction.

[0056] The guide rod 15, which is installed in the second mounting groove 11, is fixed at both ends to the groove wall of the second mounting groove 11. The second slider 16 is sleeved on the guide rod 15 and slides with the guide rod 15, and the guide rod 15 provides linear guidance to the second slider 16. The first slider 14 extends out of the first mounting groove 10 on the side facing the second slider 16, and the second slider 16 extends out of the second mounting groove 11 on the side facing the first slider 14. The mounting plate 17 is located between the two support legs 8, and its two ends are fixedly connected to the first slider 14 and the second slider 16, respectively. The length direction of the mounting plate 17 is parallel to the width direction of the conveyor belt 1, and the side of the mounting plate 17 facing the conveyor belt 1 is used to mount the electric suction cup 6, or the mounting plate 17 itself serves as a support structure for the electric suction cup 6.

[0057] When the height of the electric suction cup 6 needs to be adjusted, the first motor 13 starts and drives the first lead screw 12 to rotate via the coupling. The first lead screw 12 drives the first slider 14 to slide along the first mounting groove 10 via the lead screw and nut pair. When the first slider 14 moves, it drives the second slider 16 to slide synchronously along the guide rod 15 via the mounting plate 17, and the mounting plate 17 moves as a whole in the height direction.

[0058] During the object transfer process, the electrically driven gantry 5 moves along the electrically guided rail 7 to the object on the conveyor belt 1 via the electric wheels 9. The first motor 13 starts, causing the mounting plate 17 to drive the electric suction cup 6 towards the conveyor belt 1, where the electric suction cup 6 picks up the object. After picking up the object, the first motor 13 reverses its direction, and the mounting plate 17 drives the electric suction cup 6 away from the conveyor belt 1, removing the object from the conveyor belt 1. Subsequently, the electrically driven gantry 5 moves along the electrically guided rail 7 to the storage cabinet 2, and the first motor 13 again drives the mounting plate 17 towards the storage position 3, placing the object into the target storage position 3. After the electric suction cup 6 releases the object, the mounting plate 17 resets, completing the object transfer and storage.

[0059] Example 4:

[0060] See Figure 2 Based on the above embodiments, optionally, the mounting plate 17 has a third mounting groove 18 along its length direction, a second lead screw 19 is rotatably mounted in the third mounting groove 18, a second motor 20 is axially connected to one end of the second lead screw 19, and the second motor 20 is mounted in the third mounting groove 18, and a third slider 21 is slidably connected to the second lead screw 19 through a lead screw nut pair, and the third slider 21 is slidably engaged with the third mounting groove 18.

[0061] Specifically, the third mounting groove 18 extends along the length of the mounting plate 17, which is parallel to the width of the conveyor belt 1. Therefore, the third mounting groove 18 also extends along the width of the conveyor belt 1. The second lead screw 19 is rotatably supported in a bearing housing via a bearing, allowing it to rotate around its own axis within the third mounting groove 18. The second motor 20 is fixedly mounted at one end of the third mounting groove 18. The end of the second lead screw 19 near the second motor 20 can be connected to the output shaft of the second motor 20 via a coupling, or it can be directly fixedly connected. A lead screw nut is fixedly embedded in the third slider 21, forming a lead screw nut pair with the second lead screw 19. Both sides of the third slider 21 slide in contact with the groove wall of the third mounting groove 18 to restrict the rotation of the third slider 21 with the second lead screw 19 and provide linear guidance for the third slider 21 along the length of the third mounting groove 18. The third slider 21 is provided with a connecting structure for connecting with the electric suction cup 6, so that when the third slider 21 slides along the third mounting groove 18, it can drive the electric suction cup 6 to move synchronously along the width direction of the conveyor belt 1.

[0062] During the object transfer process, the detection camera 4 captures image information of the object on the conveyor belt 1 and determines the object's size information based on the image information, thus identifying the target storage location 3 from the storage cabinet 2. The electrically driven gantry 5 moves along the electric guide rail 7 via the electric wheels 9 to the vicinity of the object on the conveyor belt 1. If there is a deviation between the object's position in the width direction of the conveyor belt 1 and the electric suction cup 6, the second motor 20 starts, driving the second lead screw 19 to rotate. The second lead screw 19 drives the third slider 21 to slide along the third mounting groove 18 through the lead screw nut pair, thereby driving the electric suction cup 6 to move along the width direction of the conveyor belt 1, aligning the electric suction cup 6 with the object on the conveyor belt 1. Subsequently, the first motor 13 drives the first lead screw 12 to rotate, driving the mounting plate 17 to move in the height direction through the first slider 14, causing the electric suction cup 6 to move closer to the conveyor belt 1 and adsorb the object. After adsorption, the first motor 13 reverses its drive, and the mounting plate 17 drives the electric suction cup 6 to move away from the conveyor belt 1, causing the object to leave the conveyor belt 1.

[0063] The electrically driven gantry 5 continues to move along the electric guide rail 7 towards the storage cabinet 2. Upon reaching the vicinity of the storage cabinet 2, using the horizontal and vertical coordinates of the target storage location 3 within the storage cabinet 2 as a reference, the second motor 20 restarts, driving the third slider 21 to slide along the third mounting groove 18 via the second lead screw 19. This causes the electric suction cup 6 to move the object along the width direction of the conveyor belt 1 until it aligns with the horizontal coordinates of the target storage location 3. Subsequently, the first motor 13 drives the mounting plate 17 to move along the vertical direction, aligning the electric suction cup 6 with the vertical coordinates of the target storage location 3. Afterward, the electrically driven gantry 5 moves along the electric guide rail 7 to the target storage location 3 and places the object into it. After the electric suction cup 6 releases the object, all sliders reset, completing one object transfer and storage cycle.

[0064] Optionally, the end of the third slider 21 facing away from the third mounting groove 18 extends out of the third mounting groove 18 and is connected to a U-shaped frame 22. A rotating shaft 23 is rotatably mounted between the two arms of the U-shaped frame 22. A third motor 24 is drivenly connected to one axial end of the rotating shaft 23. A connecting rod 25 is fixed in the middle of the rotating shaft 23. The end of the connecting rod 25 away from the rotating shaft 23 is connected to the electric suction cup 6.

[0065] Specifically, the end of the third slider 21 facing away from the third mounting groove 18 is fixedly connected to the closed end of the U-shaped frame 22 by bolts or welding. The two arms of the U-shaped frame 22 are arranged opposite to each other, and the rotating shaft 23 is rotatably supported between the two arms by bearings. The housing of the third motor 24 is fixed to one arm of the U-shaped frame 22, and the output shaft of the third motor 24 is drivenly connected to one end of the rotating shaft 23, for example, by a coupling or by direct fixing. One end of the connecting rod 25 is sleeved and fixed to the middle of the rotating shaft 23, and the other end of the connecting rod 25 is fixedly connected to the electric suction cup 6 by bolts. The electric suction cup 6 can rotate around the axis of the rotating shaft 23 with the rotating shaft 23, thereby swinging in a plane perpendicular to the axis of the rotating shaft 23 to adjust the suction direction.

[0066] During operation, the electrically driven gantry 5 moves the mounting plate 17 and the electric suction cup 6 to the vicinity of the object on the conveyor belt 1. If there is an angular deviation between the surface of the object to be suctioned and the suction end of the electric suction cup 6, the third motor 24 starts, driving the rotating shaft 23 to rotate via the coupling. The rotating shaft 23 drives the connecting rod 25 to swing around the axis of the rotating shaft 23, thereby causing the electric suction cup 6 to rotate to an angle suitable for the surface of the object to be suctioned. Subsequently, the electric suction cup 6 suctions the object. After suction, the third motor 24 can maintain the current position or make minor adjustments in the reverse direction to keep the object in a stable posture during transportation.

[0067] The electrically driven gantry 5 continues to move along the electric guide rail 7 to the storage cabinet 2. When the opening direction of the target storage position 3 does not match the current posture of the object, the third motor 24 starts again, driving the connecting rod 25 and the electric suction cup 6 to rotate via the rotating shaft 23, causing the object to rotate around the axis of the rotating shaft 23 with the electric suction cup 6, adjusting it to a placement posture suitable for the target storage position 3. Then, the object is placed into the target storage position 3. After the electric suction cup 6 releases the object, the third motor 24 drives the electric suction cup 6 to reset, completing one object transfer and storage cycle.

[0068] Example 5:

[0069] See Figure 1 , 3 4. Based on the above embodiments, optionally, each of the storage positions 3 is provided with an access port, and each access port is hinged with a sealing door 26. A door drive locking component is provided between the sealing door 26 and the corresponding storage position 3, and each of the storage positions 3 is provided with a status indicator light 27.

[0070] Specifically, each storage compartment 3 has an access port on one side facing the electrically driven gantry 5, which is used for items to enter or exit the storage compartment 3. A hinge, which can be a hinge or a latch, is fixed to the edge of the access port. A sealing door 26 is rotatably connected to one edge of the access port via the hinge, allowing the sealing door 26 to rotate relative to the storage compartment 3 about the axis of the hinge to open or close the access port. The sealing door 26 can have a plate-like structure, the shape of which is adapted to the access port.

[0071] A door drive locking mechanism is located between the sealed door 26 and the corresponding storage position 3. It drives the sealed door 26 to rotate around the hinge, enabling automatic opening and closing of the sealed door 26. After the sealed door 26 is closed, it locks the sealed door 26 to prevent accidental opening. The door drive locking mechanism can be an electric push rod or a motor lock, etc., integrating both driving and locking functions. The aforementioned door drive locking mechanism is prior art, and its specific structure and working principle are well known to those skilled in the art, and will not be described in detail here.

[0072] Status indicator lights 27 are configured one-to-one with each storage bit 3 to display the status of the corresponding storage bit 3. The status indicator lights 27 can use different colors or different flashing patterns to distinguish between idle, selected, and occupied states.

[0073] During the storage process, once the target storage location 3 is determined, the status indicator 27 of the corresponding storage location 3 switches to the selected state. The door drive lock is released, and the sealing door 26 is automatically opened. The electric gantry 5 drives the electric suction cup 6 to move the object to the target storage location 3, and the object is placed into the storage location 3 through the access port. Subsequently, the door drive lock closes the sealing door 26, and locks it after it closes. The status indicator 27 switches to the occupied state, completing the storage of the object in storage location 3.

[0074] Optionally, it also includes a controller 28, which is electrically connected to the conveyor belt 1, the detection camera 4, the electric suction cup 6, the first motor 13, the second motor 20, the third motor 24, the electric wheel 9, the door drive lock and the status indicator light 27.

[0075] Specifically, the image signal output terminal of the detection camera 4 is connected to the signal input interface of the controller 28. The conveyor belt 1, electric suction cup 6, first motor 13, second motor 20, third motor 24, electric wheel 9, door drive locking component, and status indicator light 27 are respectively connected to the signal output interface of the controller 28. The controller 28 sends start / stop signals to the conveyor belt 1 via signal lines to control the operation or stop of the conveyor belt 1; sends drive signals to the electric wheel 9 to control the electric drive gantry 5 to move along the electric guide rail 7; sends drive signals to the first motor 13, second motor 20, and third motor 24 respectively to control the position adjustment of the electric suction cup 6 in the height, lateral, and angular directions; sends on / off signals to the electric suction cup 6 to control its suction and release of objects; sends open or close signals to the door drive locking component to control the automatic opening or closing of the sealed door 26 and lock it after closing; and sends status display signals to the status indicator light 27 to indicate the idle, selected, or occupied status of the corresponding storage position 3.

[0076] During the object storage process, the controller 28 receives object image information captured by the detection camera 4 and determines the object size based on this image information. After determining the target storage location 3 from the storage cabinet 2 according to the object size, the controller 28 sends a selected signal to the corresponding status indicator 27, controlling the status indicator 27 corresponding to the storage location 3 to display the selected status. At the same time, the controller 28 sends a movement signal to the electric wheel 9, causing the electric gantry 5 to move to the object on the conveyor belt 1; it sends position adjustment signals to the first motor 13, the second motor 20, and the third motor 24, causing the electric suction cup 6 to align with the object; and it sends a suction signal to the electric suction cup 6, causing it to pick up the object. Subsequently, the controller 28 sends a movement signal to the electric wheel 9, causing the electric gantry 5 to move towards the target storage location 3. After reaching the target storage location 3, the controller 28 sends an unlock signal to the door drive locking mechanism, causing the sealing door 26 to open; the controller 28 then controls the first motor 13, the second motor 20, and the third motor 24 to operate, placing the object into the target storage location 3. Then, the controller 28 sends a release signal to the electric suction cup 6, causing the object to detach from the electric suction cup 6 and fall into the storage position 3. The controller 28 sends a locking signal to the door drive locking component corresponding to the sealing door 26, causing the sealing door 26 to close and lock; at the same time, the controller 28 sends an occupied signal to the status indicator light 27 corresponding to the storage position 3, completing one object storage cycle.

[0077] Example 6:

[0078] See Figures 1 to 4 Based on the above embodiments, this application provides a storage method applied to a logistics platform that facilitates the storage of finished goods, as described above. The method includes:

[0079] Start conveyor belt 1, and stop conveyor belt 1 when an object is detected to have arrived at the collection area;

[0080] Acquire image information of the object on conveyor belt 1, and determine the size information of the object based on the image information, wherein the size information includes three-dimensional outline dimensions or equivalent occupied space;

[0081] Based on the size information of the object, a target storage location 3 matching the object is determined from multiple storage locations 3 of different specifications that are currently idle in the storage cabinet 2;

[0082] The electric gantry crane 5 is controlled to move the electric suction cup 6 to the object on the conveyor belt 1 and pick up the object;

[0083] The electric gantry 5 is controlled to move the electric suction cup 6 and the object to the target storage position 3, the target storage position 3 is opened, and the electric suction cup 6 is controlled to move to place the object into the target storage position 3.

[0084] Control the electric suction cup 6 to release the object and close the target storage location 3.

[0085] Specifically, conveyor belt 1 is started, and the object to be stored moves along the conveying direction with conveyor belt 1. When the object reaches the acquisition area of ​​detection camera 4, controller 28 controls conveyor belt 1 to stop running, so that the object stays in the acquisition area. Here, the acquisition area refers to the area directly below detection camera 4.

[0086] The detection camera 4 acquires image information of the object and sends it to the controller 28. Based on the image information, the controller 28 extracts the object's contour using an image recognition algorithm and, combined with the calibration parameters of the detection camera 4, determines the object's size information, including its three-dimensional outline dimensions or equivalent occupied space. The equivalent occupied space refers to the three-dimensional space occupied by the irregular object described by an equivalent regular geometric solid, such as the minimum circumscribed cuboid volume of the object or the projected area of ​​the object on the placement surface. It is used to compare with the capacity of storage space 3 to determine whether the object can be placed in a certain storage space 3, and is particularly suitable for irregularly shaped finished objects. The image recognition algorithm can employ commonly used methods in existing technologies such as edge detection, contour extraction, and camera calibration, which will not be elaborated upon here.

[0087] The controller 28 obtains the size information of multiple storage slots 3 of different specifications that are currently idle in the storage cabinet 2, and executes an intelligent matching algorithm based on the size information of the object. From all the idle storage slots 3 that can accommodate the object, it selects the one with the smallest space margin as the target storage slot 3, and retrieves the vertical coordinate, horizontal coordinate and height coordinate of the target storage slot 3 in the storage cabinet 2.

[0088] The controller 28 controls the electric wheel 9 to roll along the electric guide rail 7, driving the electric gantry frame 5 to move to the object on the conveyor belt 1. Subsequently, controller 28, based on the actual position of the object on conveyor belt 1, controls the first motor 13 to drive the first lead screw 12 to rotate, which in turn drives the first slider 14 to slide along the first mounting groove 10 via the lead screw and nut pair. Simultaneously, the second slider 16 slides synchronously along the guide rod 15, and the mounting plate 17 drives the electric suction cup 6 to approach the object on conveyor belt 1 in the height direction. Controller 28 then controls the second motor 20 to drive the second lead screw 19 to rotate, which in turn drives the third slider 21 to slide along the third mounting groove 18 via the lead screw and nut pair. This, in turn, drives the electric suction cup 6 to move along the width direction of conveyor belt 1 via the U-shaped frame 22, aligning the electric suction cup 6 with the suction position of the object. Controller 28 then controls the third motor 24 to drive the rotating shaft 23 to rotate, which, via the connecting rod 25, drives the electric suction cup 6 to rotate around the axis of the rotating shaft 23 to the optimal suction angle, adapting the electric suction cup 6 to the surface of the object. Finally, controller 28 controls the electric suction cup 6 to generate negative pressure by energizing it, thus suctioning the object.

[0089] The controller 28 controls the first motor 13 to drive the first lead screw 12 in reverse, causing the mounting plate 17 to move the electric suction cup 6 and the object away from the conveyor belt 1 in the height direction, and the object leaves the conveyor belt 1. Subsequently, the controller 28 controls the electric wheel 9 to roll along the electric guide rail 7, driving the electric gantry frame 5 and the suctioned object to move towards the storage cabinet 2.

[0090] The controller 28 controls the electric wheel 9 to drive the electric gantry frame 5 to move the moving parts to the front of the access port of the target storage position 3; the controller 28 controls the door body drive locking mechanism corresponding to the target storage position 3 to operate, so that the sealed door 26 opens automatically, and controls the status indicator light 27 corresponding to the target storage position 3 to switch to the selected state.

[0091] Subsequently, the controller 28 controls the second motor 20 and the first motor 13 to operate according to the horizontal and vertical coordinates of the target storage location 3. The second lead screw 19 and the first lead screw 12 drive the electric suction cup 6 to move in the horizontal and vertical directions, aligning the object with the access port of the target storage location 3. The controller 28 controls the third motor 24 to drive the rotating shaft 23 to rotate, which drives the electric suction cup 6 and the object to rotate around the axis of the rotating shaft 23 via the connecting rod 25, so as to adjust the posture of the object and adapt it to the access port of the target storage location 3. Then, the controller 28 controls the first motor 13 to drive the mounting plate 17 to move towards the storage location 3, placing the object into the target storage location 3 through the access port.

[0092] After the object is placed in the target storage position 3, the controller 28 controls the electric suction cup 6 to cut off the power and stop the negative pressure, releasing the object. Subsequently, the controller 28 controls the electric gantry frame 5 to drive the electric suction cup 6 out of the target storage position 3; after the electric suction cup 6 has been withdrawn, the controller 28 controls the door body drive locking component to drive the sealing door 26 to close automatically, and locks it after the sealing door 26 is closed, while updating the status indicator light 27 corresponding to the target storage position 3 to the occupied state.

[0093] After storage is completed, the controller 28 controls the electric wheel 9 to drive the electric gantry 5 back to the initial standby position, and controls the first motor 13, the second motor 20 and the third motor 24 to reset respectively, so that the mounting plate 17, the third slider 21 and the electric suction cup 6 return to the initial position, waiting for the next storage command.

[0094] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
