Description

Technical Field

[0001] This invention belongs to the field of intelligent warehousing technology, and relates to an intelligent warehousing and receiving system and an intelligent warehousing and receiving method. Background Technology

[0002] Third-party warehouses, also known as contract warehouses or cloud warehouses, refer to a warehousing model where companies outsource their warehousing and logistics activities to external companies, which then provide comprehensive logistics services. Third-party warehouses typically employ highly intelligent warehouse management systems. However, with the increasing number of customers using third-party warehouses, there remains a need to further improve warehouse management efficiency. Furthermore, even in the process of intelligent warehouse management, there are still issues with the low fault tolerance rate in automated inbound and outbound processes, requiring manual intervention in some special cases. Therefore, it is necessary to further optimize the automated inbound process. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide an intelligent warehousing and receiving system and an intelligent warehousing and receiving method.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An intelligent warehousing and receiving system includes an receiving conveyor mechanism and, sequentially arranged along the conveying direction of the receiving conveyor mechanism, a depalletizing robot, a QR code recognition mechanism, a box rotation mechanism, and a box flipping mechanism. The depalletizing robot is used to place stacked boxes flat onto the receiving conveyor mechanism. The receiving conveyor mechanism is used to convey the boxes to the box flipping mechanism. The QR code recognition mechanism is communicatively connected to a warehouse management system and is used to recognize the QR code information on the boxes and input it into the warehouse management system, as well as to recognize the location of the QR code on the box and the size of the box and add the above information to the QR code information of the box. The tin box rotating mechanism is used to rotate the tin boxes so that the QR codes on each tin box are in the same position; the tin box flipping mechanism is used to vertically flip the tin boxes so that the side with the QR code is facing upwards; a packing robot and multiple tin box packing stations are set on one side of the tin box flipping mechanism, and turnover boxes are placed on the tin box packing stations; the packing robot is connected to the warehouse management system, and the warehouse management system is equipped with a turnover box allocation unit, which is used to allocate turnover boxes according to the information of the tin boxes, and the packing robot is used to place the tin boxes on the tin box flipping mechanism into the corresponding turnover boxes.

[0006] Furthermore, the QR code recognition mechanism includes a device bracket mounted on the inbound conveyor mechanism. The device bracket has a first extension bracket and a second extension bracket extending outward from both sides of the inbound conveyor mechanism. A first scanning device is mounted on the first extension bracket, and a second scanning device is mounted on the second extension bracket. A third scanning device and a fourth scanning device are mounted on the front and rear ends of the device bracket along the conveying direction of the inbound conveyor mechanism, respectively. A 3D depth camera is also mounted on the device bracket.

[0007] Furthermore, the inbound conveying mechanism is also connected to an abnormality handling conveying mechanism and a return conveying mechanism, and a sixth barcode scanning device is provided between the abnormality handling conveying mechanism and the return conveying mechanism; the inbound conveying mechanism is also used to divert the boxes that are identified as abnormal by the barcode recognition mechanism to the abnormality handling conveying mechanism, and the abnormality handling conveying mechanism is used to convey the boxes diverted from the inbound conveying mechanism to the abnormality handling station, and to return the boxes that have been manually handled at the abnormality handling station to the inbound conveying mechanism.

[0008] The sixth scanning device is used to identify the QR code information on the material box and transmit it to the warehouse management system before the material box enters the material box flipping mechanism. When the material box information is not in the warehouse management system, the inbound conveying mechanism will also divert the material box to the return conveying mechanism. The return conveying mechanism is used to return the material box diverted from the inbound conveying mechanism to the feeding end of the inbound conveying mechanism.

[0009] Furthermore, the inbound conveying mechanism includes a first conveying unit, a second conveying unit, a third conveying unit, a fourth conveying unit, a first reversing unit, a second reversing unit, and a third reversing unit; the return conveying mechanism includes a fifth conveying unit, a sixth conveying unit, a fourth reversing unit, and a fifth reversing unit; and the abnormal handling conveying mechanism includes a seventh conveying unit and an eighth conveying unit.

[0010] The first conveying unit is connected to the second conveying unit and the seventh conveying unit respectively through the first reversing unit. The first reversing unit is provided with a feeding end, a first discharging end at a 90° angle to the feeding end, and a second discharging end opposite to the feeding end. The feeding end of the first reversing unit is connected to the discharging end of the first conveying unit, and the first discharging end of the first reversing unit is connected to the feeding end of the second conveying unit. The second discharging end of the first reversing unit is connected to the abnormal handling station through the seventh conveying unit.

[0011] The second conveying unit is connected to the third conveying unit and the eighth conveying unit respectively through the second reversing unit. The second reversing unit is provided with a first feeding end, a second feeding end at a 90° angle to the first feeding end, and a discharging end opposite to the second feeding end. The first feeding end of the second reversing unit is connected to the discharging end of the second conveying unit. The second feeding end of the second reversing unit is connected to the abnormal handling station through the eighth conveying unit. The discharging end of the second reversing unit is connected to the feeding end of the third conveying unit.

[0012] The third conveying unit is connected to the fourth conveying unit and the fifth conveying unit respectively through the third reversing unit. The third reversing unit is provided with a feeding end, a first discharging end at a 90° angle to the feeding end, and a second discharging end opposite to the feeding end. The feeding end of the third reversing unit is connected to the discharging end of the third conveying unit. The first discharging end of the third reversing unit is connected to the material box flipping mechanism through the fourth conveying unit. The second discharging end of the third reversing unit is connected to the feeding end of the fifth conveying unit.

[0013] The fourth reversing unit includes a feeding end and a discharging end at a 90-degree angle to the feeding end. The feeding end of the fourth reversing unit is connected to the discharging end of the fifth conveying unit, and the discharging end of the fourth reversing unit is connected to the feeding end of the sixth conveying unit. The fifth reversing unit includes a feeding end and a discharging end at a 90-degree angle to the feeding end. The feeding end of the fifth reversing unit is connected to the discharging end of the sixth conveying unit, and the discharging end of the fifth reversing unit is connected to the feeding end of the first conveying unit.

[0014] Furthermore, it also includes a manual warehousing mechanism, which is used to transfer manually unstacked boxes to a warehousing conveyor mechanism, and to manually load the boxes into turnover boxes.

[0015] Furthermore, a spare turnover box conveying mechanism is provided on one side of at least one of the aforementioned box packing stations. The spare turnover box conveying mechanism is provided with multiple storage positions for storing turnover boxes. The spare turnover box conveying mechanism is used to convey the turnover boxes at the storage positions to the box packing station. A first detection unit is provided at the storage position of the spare turnover box conveying mechanism near the discharge end; a second detection unit is provided at the storage position of the spare turnover box conveying mechanism near the feed end.

[0016] A smart warehousing and receiving method includes the following steps:

[0017] S100. Place the boxes to be stored flat on the feed end of the storage conveyor in sequence.

[0018] S200: Scan the QR code on the material box on the inbound conveyor and enter the QR code information into the warehouse management system.

[0019] S300: Identify the size of the material box and allocate the corresponding turnover box according to the size of the material box;

[0020] S400: Identify the orientation of the QR code on the material box, and rotate the material box according to the orientation of the QR code on the material box so that the orientation of the QR code on each material box is in the same position.

[0021] S500: Flip the material box so that the QR code on the material box faces upwards;

[0022] S600. Place the material box into the corresponding turnover box according to the size of the material box, and put the turnover box into the warehouse after the turnover box is full.

[0023] Furthermore, before executing step S100, the receiving slip is first entered into the warehouse management system; when executing step S200, if the QR code information of the material box cannot be recognized, the following steps are performed:

[0024] S211. Manually check whether the QR code on the material box is damaged or detached. If the QR code is damaged or detached, proceed to step S212; otherwise, proceed to step S213.

[0025] S212. Re-affix the QR code to the material box and proceed to step S213;

[0026] S213. Place the material box flat on the inbound conveyor mechanism and return to execute step S200.

[0027] After performing step S200, the following steps are also performed:

[0028] S221. The warehouse management system checks whether the material box is the same as the material box on the receiving slip. If it is the same as the material box on the receiving slip, proceed to step S300; otherwise, proceed to step S222.

[0029] S222. Check if the material box is a returned material box. If it is, proceed to step S300; otherwise, proceed to step S223.

[0030] S223. Check if the material box is a material box that has been put into storage. If it is, proceed to step S224; otherwise, proceed to step S225.

[0031] S224. Feed back the QR code information of the material box to the management personnel and execute step S300;

[0032] S225. Provide feedback to the customer and modify the receiving slip or remake the QR code label for the material box according to the customer's opinion, and then proceed with step S300.

[0033] Furthermore, before executing step S500, perform the following steps:

[0034] SB11. Scan the QR code information on the material box and check whether the material box information has been entered into the warehouse management system. If it has been entered into the warehouse management system, proceed to step S500; otherwise, proceed to step SB12.

[0035] SB12. Return the material box to the feeding end of the inbound conveyor and execute step S200.

[0036] Furthermore, before performing step S100, the following steps must be performed first:

[0037] SA11. Check if the material box is damaged. If it is damaged, proceed to step SA12; otherwise, proceed to step SA15.

[0038] SA12. Place the box in a temporary storage location and report the situation to the customer. If the customer determines that the damage does not affect the integrity of the internal components of the box, proceed to step SA14; otherwise, proceed to step SA13.

[0039] SA13. Place the material box in the damaged storage location;

[0040] SA14. The material boxes are put into storage using manual storage methods;

[0041] SA15. Check if there are any irregularly shaped boxes in the material box. If there are, proceed to step SA16; otherwise, proceed to step S100.

[0042] SA16. Manually store irregularly shaped boxes and execute step S100.

[0043] In this invention, stacked boxes can be automatically packed into corresponding turnover boxes according to their size and the type of device they contain, completing the box packing and warehousing process. Furthermore, during the warehousing process, returning boxes and already-stored boxes can be queued for entry, resulting in a high degree of automation. By setting up a box rotation mechanism and a box flipping mechanism, the step of identifying the box status by the packing robot can be omitted, simplifying the robot's function and structure. Through the design of the conveyor route, boxes with damaged, missing, or incorrectly scanned QR codes can be diverted for manual handling before being re-entered into the warehousing conveyor to begin the warehousing process, improving the fault tolerance of the automated warehousing process.

[0061] The following specific examples illustrate the implementation of the present invention. The illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0062] Please see Figure 1 , Figure 1 This is a schematic diagram of one embodiment of the intelligent warehousing and receiving system of the present invention. The intelligent warehousing and receiving system of this embodiment includes an receiving conveyor mechanism and, sequentially arranged along the conveying direction of the receiving conveyor mechanism, a depalletizing robot 102, a QR code recognition mechanism 200, a box rotation mechanism 300, and a box flipping mechanism 400. An automatic depalletizing station 101 is provided on one side of the feeding end of the receiving conveyor mechanism. The depalletizing robot 102 is used to sequentially lay the stacked boxes 800 on the automatic depalletizing station 101 flat (i.e., the top surface of the boxes 800 facing upwards) onto the receiving conveyor mechanism. Since the destacking station 101 typically handles containers that are directly opened, and these containers usually contain empty boxes, fillers, and other items that do not need to be stored in the warehouse, the destacking robot 102 can also be connected to a 3D vision device (not shown in the figure). The 3D vision device can identify fillers that are not box-shaped based on the shape and size of the objects, and identify empty boxes that have not been filled by checking whether they have QR codes attached. This allows the destacking robot 102 to first remove the empty boxes and fillers and place them in the corresponding areas, and then take out the material boxes 800 from the container one by one and place them on the warehouse conveyor mechanism.

[0063] The inbound conveying mechanism is used to convey the material box 800 to the material box flipping mechanism 400. The QR code recognition mechanism 200 is communicatively connected to the warehouse management system and is used to measure the size of the material box 800 to facilitate the allocation of turnover boxes 900, and to scan the four sides of the material box 800 (the QR codes storing the device information in the material box 800 are affixed to one side of the material box 800 as required), thereby determining the side of the material box 800 where the QR code is located, recognizing the QR code information and sending it to the warehouse management system for inbound storage. The material box rotating mechanism 300 is used to rotate the material box 800 according to the side where the QR code is located (i.e., rotate the material box 800 horizontally), so that the side of the material box 800 where the QR code is located faces a predetermined direction. The output end of the material box rotating mechanism 300 is provided with a discharging mechanism. In this embodiment, the front, rear, left, and right sides of the material box 800 are defined with reference to the conveying direction of the fourth conveying unit 114. The direction when the side where the QR code is located is the rear side of the material box 800 (i.e., the side where the QR code is located faces) is defined. Figure 1 and Figure 2 The negative direction of the y-axis is used as the predetermined direction. The cassette flipping mechanism 400 is used to vertically flip the cassette 800 so that the side of the cassette 800 with the QR code is facing upwards.

[0064] A packing robot 500 and multiple packing stations 600 are provided on one side of the box flipping mechanism 400, where turnover boxes 900 are placed. Multiple partitions 910 are evenly spaced within each turnover box 900, dividing it into multiple identical box-accommodating spaces 920. Each box-accommodating space holds one box 800, allowing multiple boxes 800 to be placed separately within the turnover box 900. The packing robot 500 is communicatively connected to a warehouse management system, which includes a turnover box allocation unit (not shown in the figure). This unit allocates turnover boxes 900 based on information about the boxes 800, and the packing robot 500 places the boxes 800 from the box flipping mechanism 400 into the box-accommodating spaces 920 of the turnover box 900. The packing robot 500 is also electrically connected to a vision recognition system (not shown in the figure). A feeding robot 700 is installed at each box packing station 600. After the packing robot 500 places the box 800 into the turnover box 900, the vision recognition system locates the specific position of the box's storage space 920, enabling the feeding robot 700 to accurately place the box 800 into the predetermined storage space 920. Simultaneously, the vision recognition system also identifies whether the turnover box 900 has any remaining storage space 920. When the turnover box 900 does not have any remaining storage space 920, the feeding robot 700 removes the turnover box 900 from the box packing station 600 and delivers it to the warehouse, thus achieving automated warehousing of the box 800.

[0065] Please see Figure 2 To facilitate the diversion and merging of material boxes 800 on the inbound conveying mechanism, the inbound conveying mechanism may include a first conveying unit 111, a second conveying unit 112, a third conveying unit 113, a fourth conveying unit 114, a first reversing unit 121, a second reversing unit 122, and a third reversing unit 123. Through the reversing functions of the first reversing unit 121, the second reversing unit 122, and the third reversing unit 123, the material boxes 800 can be diverted and merged during the conveying process.

[0066] The feeding end of the first conveying unit 111 serves as the feeding end of the warehousing conveying mechanism. The QR code recognition mechanism 200 can be set on the conveying path of the first conveying unit 111. The discharging end of the first conveying unit 111 is connected to the feeding end of the second conveying unit 112 through the first reversing unit 121. In this embodiment, the first reversing unit 121 is provided with a feeding end, a first discharging end at a 90° angle to its feeding end, and a second discharging end opposite to its feeding end. The feeding end of the first reversing unit 121 is connected to the first conveying unit 111, and the first discharging end of the first reversing unit 121 is connected to the second conveying unit 112. The second discharging end of the first reversing unit 121 is used for diverting the material box 800 under special circumstances.

[0067] The material box rotation mechanism 300 can be arranged on the conveying path of the second conveying unit 112. The discharge end of the second conveying unit 112 is connected to the feed end of the third conveying unit 113 through the second reversing unit 122. In this embodiment, the second reversing unit 122 is provided with a first feed end, a second feed end at a 90° angle to the first feed end, and a discharge end opposite to the second feed end. The first feed end of the second reversing unit 122 is connected to the second conveying unit 112, and the discharge end of the second reversing unit 122 is connected to the third conveying unit 113. The second feed end of the second reversing unit 122 is used for the merging of the material boxes 800 under special circumstances.

[0068] The discharge end of the third conveying unit 113 is connected to the feed end of the fourth conveying unit 114 via the third reversing unit 123. In this embodiment, the third reversing unit 123 is provided with a feed end, a first discharge end at a 90° angle to the feed end, and a second discharge end opposite to the feed end. The feed end of the third reversing unit 123 is connected to the third conveying unit 113, and the first discharge end of the third reversing unit 123 is connected to the fourth conveying unit 114; the second discharge end of the third reversing unit 123 is used for diverting the material box 800 under special circumstances.

[0069] It should be noted that the first reversing unit 121, the second reversing unit 122, and the third reversing unit 123 only change the direction of the conveying path of the material box 800, and do not change the orientation of the four sides of the material box 800. For example, when the material box 800 enters from the feed end of the first reversing unit 121 and exits from its first discharge end, the conveying direction of the material box 800 changes from conveying along the positive x-axis to conveying along the positive y-axis; however, during this process, the front side of the material box 800 always faces the positive y-axis and does not change with the change of the conveying direction.

[0070] To facilitate the handling of anomalies during the warehousing process and to allow the processed material boxes 800 to be automatically re-entered into the warehousing process, the warehousing conveyor is also connected to an anomaly handling conveyor and a return conveyor. The warehousing conveyor is further used to divert material boxes 800 that have been identified as abnormal by the QR code recognition mechanism 200 (including material boxes 800 whose QR codes have not been scanned and material boxes 800 whose scanned QR code information does not match the warehousing slip) to the anomaly handling conveyor. The anomaly handling conveyor is used to transport the material boxes 800 diverted from the warehousing conveyor to the anomaly handling station 104, and to return the material boxes 800 that have been manually handled at the anomaly handling station 104 to the warehousing conveyor.

[0071] For returned and already-stored boxes identified by the QR code recognition device 200, the warehousing process will continue as with box 800 on the warehousing slip, without being diverted to the exception handling station 104. Returned boxes refer to boxes 800 that have been issued but need to be returned. For example, when only a portion of the loaded components in a box 800 needs to be issued, the box 800 will first be removed from the warehouse, then the required number of components will be taken out, the information of the box 800 containing the remaining components will be updated, and then the box 800 will be returned to the warehouse. This allows for automatic warehousing of these two special types of boxes—returned and already-stored boxes—eliminating the need for manual warehousing operations as in existing technologies.

[0072] Because the QR codes on the boxes 800 processed at the anomaly handling station 104 have not been scanned by the QR code recognition mechanism 200, they cannot be directly put into storage. Therefore, a sixth scanning device 103 is set up between the anomaly handling conveyor and the return conveyor. This sixth scanning device 103 can scan the QR code information of the boxes 800 again before packing to confirm whether the boxes 800 can be packed. Boxes 800 that cannot be packed will then undergo the automatic storage procedure again. The sixth scanning device 103 identifies the QR code information on the boxes 800 before they enter the box flipping mechanism 400 and transmits it to the warehouse management system. If the information of the box 800 is not in the warehouse management system, the storage conveyor will divert the box 800 to the return conveyor. The return conveyor will then return the box 800 diverted from the storage conveyor to the feeding end of the storage conveyor for the storage procedure to be repeated.

[0073] To facilitate the connection between the inbound conveying mechanism, the abnormal handling conveying mechanism, and the return conveying mechanism, the abnormal handling conveying mechanism may include a seventh conveying unit 117 and an eighth conveying unit 118. The feeding end of the seventh conveying unit 117 is connected to the second discharging end of the first reversing unit 121. The discharging end of the seventh conveying unit 117 and the feeding end of the eighth conveying unit 118 are both connected to the abnormal handling station 104. The discharging end of the eighth conveying unit 118 is connected to the second feeding end of the second reversing unit 122.

[0074] The return conveying mechanism may include a fifth conveying unit 115, a sixth conveying unit 116, a fourth reversing unit 124, and a fifth reversing unit 125. The feed end of the fifth conveying unit 115 serves as the feed end of the return conveying mechanism and is connected to the second discharge end of the third reversing unit 123. The fourth reversing unit 124 includes a feed end and a discharge end at a 90-degree angle to its feed end. The feed end of the fourth reversing unit 124 is connected to the discharge end of the fifth conveying unit 115, and the discharge end of the fourth reversing unit 124 is connected to the feed end of the sixth conveying unit 116. The fifth reversing unit 125 includes a feed end and a discharge end at a 90-degree angle to its feed end. The feed end of the fifth reversing unit 125 is connected to the discharge end of the sixth conveying unit 116, and the discharge end of the fifth reversing unit 125 serves as the discharge end of the return conveying mechanism and is connected to the feed end of the first conveying unit 111.

[0075] Please see Figure 3The QR code recognition mechanism 200 may include a device bracket 210 disposed on the first conveying unit 111. The device bracket 210 is provided with a first extension bracket 211 extending outward from the right side of the first conveying unit 111 in the conveying direction and a second extension bracket 212 extending outward from the left side of the first conveying unit 111 in the conveying direction. A first scanning device 221 is disposed on the first extension bracket 211 for scanning the QR code on the rear side of the material box 800. A second scanning device 222 is disposed on the second extension bracket 212 for scanning the QR code on the front side of the material box 800. A third scanning device 223 is disposed at the front end of the device bracket 210 along the conveying direction of the first conveying unit 111 for scanning the QR code on the right side of the material box 800. A fourth barcode scanner 224 is installed at the rear end of the equipment bracket 210 along the conveying direction of the first conveying unit 111. The fourth barcode scanner 224 is used to scan the QR code on the left side of the material box 800. Since a top surface QR code is generally also set on the top surface of the material box 800 (this top surface QR code is independent of the QR code on the side of the material box 800 and is not necessarily related), a fifth barcode scanner 225 can also be set on the equipment bracket 210 to obtain the information of the top surface QR code. The fifth barcode scanner 225 is located directly above the first conveying unit 111. A 3D depth camera 226 is also installed on the equipment bracket 210; the 3D depth camera 226 is used to measure the size of the material box 800 so as to allocate the corresponding turnover box 900 according to the size of the material box 800.

[0076] Please see Figure 4The cassette rotation mechanism 300 includes a cylinder bracket 301 mounted on the second conveying unit 112, with a lifting cylinder 330 vertically mounted on the cylinder bracket 301. The output end of the lifting cylinder 330 is connected to a connecting plate 331, and a rotating cylinder 340 is vertically mounted on the connecting plate 331. The output end of the rotating cylinder 340 is connected to a first gripper 350. When the side of the cassette 800 containing the QR code is the rear side of the cassette 800, the second conveying unit 112 directly conveys the cassette 800 to the second reversing unit 122, and the cassette rotation mechanism 300 does not perform any processing. When the side of the cassette 800 containing the QR code is not the rear side of the cassette 800, the cassette rotation mechanism 300 determines the required rotation angle of the cassette 800 based on the side containing the QR code. For example, when the side of the material box 800 containing the QR code is the front side of the material box 800, the material box 800 needs to be rotated by 180°. In this case, when the material box 800 is conveyed to directly below the first gripper 350, the second conveying unit 112 pauses conveying; the output end of the lifting cylinder 330 first extends downward, then the first gripper 350 clamps the material box 800, and the output end of the rotating cylinder 340 rotates 180°, so that the side of the material box 800 containing the QR code is the rear side of the material box 800. Afterward, the first gripper 350 releases the material box 800, and the output end of the lifting cylinder 330 retracts upward; the second conveying unit 112 continues conveying, conveying the material box 800 to the second reversing unit 122; thus, the QR codes of the material boxes 800 conveyed to the second reversing unit 122 are all located on their rear sides.

[0077] To facilitate the correction of the position of the material box 800 after it rotates, a first lateral support 310 and a second lateral support 320 can be respectively provided on both sides of the cylinder support 301. A first pushing cylinder 311 is horizontally mounted on the first lateral support 310, and a first push plate 312 is also slidably mounted on the first lateral support 310. The output end of the first pushing cylinder 311 is fixedly connected to the first push plate 312. A second pushing cylinder 321 is horizontally mounted on the second lateral support 320, and a second push plate 322 is also slidably mounted on the second lateral support 320. The output end of the second pushing cylinder 321 is fixedly connected to the second push plate 322. When the material box 800 rotates to the side where the QR code is located, the first gripper 350 releases the material box 800, and the output ends of the first pusher cylinder 311 and the second pusher cylinder 321 extend inward at the same time, so that the first pusher plate 312 and the second pusher plate 322 respectively abut against the corresponding side of the material box 800, thereby correcting the position of the material box 800.

[0078] Please continue reading. Figure 1 and Figure 2To provide an emergency handling method for manual warehousing in case of equipment failure, the intelligent warehousing system may also include a manual warehousing mechanism. This mechanism is used to convey manually unpacked material boxes 800 to the warehousing conveyor mechanism, and to manually load the material boxes 800 into turnover boxes 900. In this embodiment, the manual warehousing mechanism includes a ninth conveyor unit 119 and a manual warehousing station 105. A manual unpacking station 106 is provided on one side of the manual warehousing station 105. The second reversing unit 122 is also provided with a third feeding end opposite to its first feeding end. The feeding end of the ninth conveyor unit 119 is connected to the manual warehousing station 105, and its discharging end is connected to the third feeding end of the second reversing unit 122. When the depalletizing robot 102 malfunctions and manual depalletizing is required, the container is placed at the manual depalletizing station 106. At the manual warehousing station 105, the container 800 is manually removed from the depalletizing station 106 and conveyed via the ninth conveyor unit 119 to the third feed end of the second reversing unit 122. The third feed end of the second reversing unit 122 is connected to its discharge end. The container 800 sequentially passes through the third conveyor unit 113, the third reversing unit 123, and the return conveyor mechanism back to the feed end of the first conveyor unit 111, thus entering the automatic warehousing process. When equipment malfunction prevents the automatic warehousing process from being implemented, manual depalletizing and manual warehousing are performed directly at the manual warehousing station 105. The equipment used for manual warehousing is existing technology and will not be described in detail here.

[0079] Please see Figure 5 The fourth conveying unit 114 has a material box flipping mechanism 400 at its discharge end. This mechanism flips the material box 800 (i.e., rotates it vertically) so that its rear side faces upwards. The flipping mechanism 400 may include an inclined surface 410 connected to the output end of the fourth conveying unit 114 and a flipping chamber 420 connected to the lower end of the inclined surface 410. The tilt angle of the flipping chamber 420 is the same as that of the inclined surface 410 to catch the material box 800 sliding down from the inclined surface 410. The flipping chamber 420 is connected to a rotation drive device 430, which drives the flipping chamber 420 to rotate, causing its opening to face upwards, thus making the rear side of the material box 800 face upwards. Since the QR codes on the material boxes 800 delivered from the fourth conveying unit 114 are all on their rear sides, after the material box 800 is flipped, the QR codes on the material box 800 all face upwards.

[0080] The packing robot 500 has a second gripper 510 at its front end for gripping the box 800. After gripping the box 800 with the second gripper 510, the robot places the box 800 into the corresponding box-accommodating space 920 of the turnover box 900, and then releases the second gripper 510. To avoid interference between the second gripper 510 and the partition 910 when placing the box 800 into the turnover box 900, the height of the partition 910 can be less than the height of the box 800 after it is flipped. At the same time, the distance between adjacent partitions 910 in the turnover box 900 can be slightly greater than the thickness of the box 800 (i.e., the dimension of the box 800 along the y-axis after it is flipped), so that the second gripper 510 can safely place the box 800 into the turnover box 900, and prevent the second gripper 510 from releasing the box 800 before it contacts the bottom of the turnover box 900, which could damage the components inside the box 800. Since the QR codes on the boxes 800 are all facing upwards before the packing robot 500 picks them up, the robot 500 does not need to adjust the orientation of the boxes 800. It can simply place the boxes 800 into the turnover box 900 with their original orientation to ensure that the QR codes on the boxes 800 are all facing upwards, facilitating scanning during outbound processing. This also simplifies the process of the packing robot 500 moving the boxes 800 into the turnover box 900.

[0081] To improve packing efficiency, in this embodiment, each packing station 600 corresponds to a type of box 800, and each type of box 800 corresponds to a type of turnover box 900. The only difference between different types of turnover boxes 900 is the size of their internal box-holding space 920; their external dimensions can be the same, thereby improving versatility during inbound and outbound operations.

[0082] To simplify the structure of the intelligent warehousing and receiving system, this embodiment uses six commonly used sizes of 800 boxes as universal boxes, and adopts an automatic receiving method, along... Figure 1 and Figure 2 The x-axis of the equipment has six box packing stations 600, each of which holds a turnover box 900 that matches the size of the box 800 at that station. The other boxes 800, besides the six commonly used sizes, are extremely rare and can be stored manually to save on equipment costs.

[0083] Since the usage quantities of the six types of general-purpose boxes can still vary significantly, these six types of general-purpose boxes can be further divided into frequently used boxes and scarce boxes based on their usage quantity. A spare turnover box conveying mechanism 610 is provided on one side of the box packing station 600 corresponding to the frequently used box. At least one turnover box 900 corresponding to the box packing station 600 is placed on the spare turnover box conveying mechanism 610 for backup. For example, multiple storage positions for turnover boxes 900 can be provided on the spare turnover box conveying mechanism 610, with each storage position used to place one turnover box 900 corresponding to the box packing station 600. When the turnover box 900 at the box packing station 600 is full, the feeding robot 700 puts the full turnover box 900 into the warehouse. At the same time, the spare turnover box conveying mechanism 610 can quickly transfer the turnover box 900 to the box packing station 600 to avoid the box packing robot 500 stopping and affecting the packing efficiency if there are no turnover boxes 900 at the box packing station 600. "Full box" means that all the boxes 800 allocated to that turnover box 900 by the warehouse management system have been filled into the turnover box 900. Since the number of boxes 800 that meet the conditions is not necessarily a multiple of the box capacity 920 of the turnover box 900, the box capacity 920 of the turnover box 900 may not be completely full when the box is full.

[0084] After the feeding robot 700 puts a full box of turnover boxes 900 into storage, it also replenishes the turnover boxes 900 at the box packing station 600. For the box packing station 600 corresponding to commonly used boxes, the feeding robot 700 replenishes the turnover boxes 900 to the spare turnover box conveyor mechanism 310 of the box packing station 600, and replenishes the turnover boxes 900 to the box packing station 600 through the spare turnover box conveyor mechanism 610. For the box packing station 600 corresponding to boxes with few turnover boxes, since there is no corresponding spare turnover box conveyor mechanism 610, the feeding robot 700 directly replenishes the turnover boxes 900 at the box packing station 300.

[0085] The spare turnover box conveying mechanism 610 may include a plurality of conveying rollers 611 arranged sequentially along the conveying direction. A baffle 612 is provided on each side of the plurality of conveying rollers 611, and the distance between two baffles 612 is adapted to the width of the turnover box 900. Thus, the turnover box 900 can be conveyed via the conveying rollers 611, and the baffles 612 on both sides can limit the movement of the turnover box 900, preventing it from shifting during conveying.

[0086] To monitor the number of turnover boxes 900 on the spare turnover box conveying mechanism 610 for timely replenishment, a first detection unit 621 is installed at the storage position near the discharge end of the spare turnover box conveying mechanism 610; a second detection unit 622 is installed at the storage position near the feed end of the spare turnover box conveying mechanism 610. When the second detection unit 622 does not detect a turnover box 900, it indicates that there is space available at the storage position, and a command to replenish the turnover box 900 can be sent to the feeding robot 700. This causes the feeding robot 700 to add a task to replenish the turnover box 900 on the spare turnover box conveying mechanism 610 in its task bar, and replenish the turnover box 900 on the spare turnover box conveying mechanism 610 as needed. When the first detection unit 621 does not detect the turnover box 900, it means that there is no turnover box 900 on the spare turnover box conveying mechanism 610 and it is in urgent need of replenishment. At this time, an emergency replenishment command for turnover box 900 is sent to the feeding robot 700, so that the feeding robot 700 raises the task level of replenishing turnover box 900 and prioritizes the task of replenishing turnover box 900 to the spare turnover box conveying mechanism 610.

[0087] In this embodiment, the stacked boxes 800 in containers such as shipping containers can be loaded into corresponding turnover boxes 900 according to the size of the box 800 and the type of the loaded device (this embodiment mainly targets small devices such as electronic devices). This ensures that the boxes 800 in the same turnover box 900 are all of the same size, which facilitates the storage and management of the boxes 800. The QR code recognition mechanism 200 can determine the side of the box 800 where the QR code is located, and the box rotation mechanism 300 can rotate the side of the box 800 so that the QR codes on the side of the box 800 are all facing backward. After being flipped by the box flipping mechanism 400, the QR codes on the box 800 are all facing upward. When the packing robot 200 puts the box 800 into the turnover box 900, there is no need to adjust the orientation of the box 800, which simplifies the process of the packing robot 200 moving the box 800 into the turnover box 900. In addition, it can manually handle situations such as damaged, missing, or incorrectly scanned QR codes before restarting the warehousing process. It also has a manual warehousing function in emergency situations, demonstrating not only a high degree of automation but also strong fault tolerance. The spare turnover box conveying mechanism 310 can promptly replenish turnover boxes 900 to the corresponding box packing station 300 of the commonly used material boxes 800, improving packing efficiency.

[0088] Please see Figure 6 , Figure 6 This is a flowchart of one embodiment of the intelligent warehousing and receiving method of the present invention. The intelligent warehousing and receiving method of this embodiment includes the following steps:

[0089] SA11. Upon receiving the container materials, first remove the cover and some of the side panels. Then, manually or visually inspect the 800 boxes to be stored for any damage. If any are found, the components inside the damaged box may be damaged. Proceed to step SA12 for confirmation. Otherwise, the box is intact, and proceed to step SA14 to check for irregularly shaped boxes. Although there are various sizes of 800 boxes, only a few sizes are commonly used for storing electronic components. Therefore, in this embodiment, based on the number of 800 boxes used, automatic storage is only performed on the six most commonly used sizes. Other sizes of 800 boxes are defined as irregularly shaped boxes.

[0090] SA12. Place the damaged box 800 into a temporary storage location and report the situation to the customer. If the customer determines that the damage does not affect the integrity of the internal components of box 800, proceed with step S100 to complete the warehousing procedure. Otherwise, proceed with step SA13.

[0091] SA13. Remove the damaged box 800 from the container and place it in the damaged storage location for later return to the customer; proceed with step S100 for the warehousing procedure for the remaining box 800.

[0092] SA14. Check if there are any irregularly shaped boxes among the 800 boxes to be put into storage. Irregularly shaped boxes refer to 800 boxes that are not in the six standard sizes. If irregularly shaped boxes are found, proceed to step SA15 to put them into storage separately; otherwise, proceed to step S100 to start the automatic storage process.

[0093] SA15. Manually insert the irregularly shaped boxes into the warehouse; then, execute step S100, and the remaining boxes 800 will begin the automatic insertion process. Since the number of irregularly shaped boxes is extremely small, manual insertion avoids adding a large number of related equipment for the insertion of a few irregularly shaped boxes, simplifying the structure of the insertion system; for example, the gripper used to pick up the boxes 800 can have a simplified gripper structure and will not increase the workload of management personnel.

[0094] S100. First, the warehouse entry order is entered into the warehouse management system. Then, the depalletizing robot 102 starts loading materials and places the material boxes 800 that need to be put into the warehouse on the first conveying unit 111 of the warehouse entry conveying mechanism in sequence. The materials are then conveyed to the automatic warehouse entry station through the warehouse entry conveying mechanism.

[0095] S200 and QR code recognition mechanism 200 scan the QR code on the material box 800 on the first conveying unit 111 and enter the QR code information into the warehouse management system. In this step, if the QR code recognition mechanism 200 fails to recognize the QR code information on the material box 800, it indicates that there may be a problem with the QR code label, and the following steps are executed:

[0096] S211. The material box 800 is output from the second discharge end of the first reversing unit 121 and conveyed to the abnormal handling station 104 via the seventh conveying unit 117. The QR code on the material box 800 is manually inspected for damage or detachment. If the QR code is damaged or detached, step S212 is executed; otherwise, it indicates that the failure to scan the code is just a normal error of the QR code recognition mechanism 200, and step S213 is executed.

[0097] S212. Re-affix the QR code to the material box 800 to facilitate automatic storage of the material box 800, and then proceed to step S213.

[0098] S213. Place the material box 800 flat on the eighth conveyor unit 118. The material box 800 returns to the warehousing conveyor mechanism from the second output end of the second reversing unit 122. Then, in step S200, the material box 800 restarts the warehousing process.

[0099] After completing step S200, the following steps can also be performed:

[0100] S221. The warehouse management system compares the information entered after scanning the barcode with the information on the receiving slip to check whether the material box 800 is the same material box on the receiving slip. If it is the same material box on the receiving slip, proceed to step S300 and carry out the receiving procedure normally; otherwise, proceed to step S222 to confirm the information of the material box 800.

[0101] S222. Check if the material box 800 is a returned material box. If it is, proceed to step S300 to continue the normal warehousing procedure. Otherwise, proceed to step S223 to further confirm the information of the material box 800. This step allows the returned material box to be automatically inserted into the warehousing order on which it is currently being stored, eliminating the need for manual warehousing as required by existing technologies.

[0102] S223. Check if the material box 800 is already in storage. If so, proceed to step S224; otherwise, it indicates that the information of the material box 800 is abnormal, and proceed to step S225. During the storage process, the material box 800 may fall off the feeding robot 700, causing storage failure. This step allows the material box 800 that has experienced such a situation to be directly re-stored without manual inquiry and storage.

[0103] S224. Feedback the QR code information of the material box 800 to the management personnel, reminding them to find the reason why the material box 800 failed to be successfully put into storage, so as to facilitate future improvements. Afterwards, execute step S300 to proceed with the normal storage procedure.

[0104] S225. If the material box 800 is neither a returned material box nor an already received material box, it means that the material box 800 should be a material box on the receiving slip that is currently being received, and the QR code information of the material box 800 does not match the information on the receiving slip. In this case, it is necessary to provide feedback to the customer and modify the receiving slip or remake the QR code label of the material box 800 according to the customer's opinion so that the QR code information of the material box 800 matches the receiving slip, and then execute step S300 to carry out the receiving procedure.

[0105] S300: Simultaneously with step S200, the 3D depth camera 226 of the QR code recognition mechanism 200 also identifies the dimensions of the material boxes 800 on the first conveying unit 111 and allocates corresponding turnover boxes 900 according to the dimensions of the material boxes 800. For ease of management, in this embodiment, material boxes 800 of the same size and containing the same type of components from the same inbound order are allocated to the same turnover box 900, and material boxes 800 containing components from the same production batch are preferentially allocated to the same turnover box 900.

[0106] S400. Simultaneously with steps S200 and S300, the QR code recognition mechanism 200 also identifies the orientation of the QR code on the material box 800. Then, on the second conveying unit 112, the material box rotation mechanism 300 rotates the material box 800 according to the orientation of the QR code, ensuring that the QR code on each material box 800 is in the same position. In this embodiment, after rotation, the side of the material box 800 where the QR code is located is the rear side.

[0107] Afterwards, the material box 800 enters the third conveying unit 113 through the second reversing unit 122, and performs the following steps before executing step S500:

[0108] SB11: The sixth barcode scanner 103, positioned at the location of the QR code on the material box 800, scans the QR code information of the material box 800 and checks whether the information of the material box 800 has been entered into the warehouse management system. If it has been entered into the warehouse management system, proceed to step S500 to prepare for packing and storage in the main warehouse. Otherwise, it indicates that the material box 800 has been processed by the abnormal processing station 104 (i.e., step S213 has been executed), and step SB12 is executed to re-enter the warehouse.

[0109] SB12 and the third reversing unit 123 divert the material box 800 from its second discharge end to the return conveying mechanism. The material box 800 is then transferred back to the feed end of the first conveying unit 111 via the fifth conveying unit 115, the fourth reversing unit 124, the sixth conveying unit 116 and the fifth reversing unit 125 in sequence, and the S200 step is performed to re-enter the material box into the warehouse.

[0110] S500, the material box flipping mechanism 400 flips the material box 800. In this embodiment, the material box flipping mechanism 400 will flip the material box 800 forward by 90 degrees, so that the rear side of the material box 800 faces upward (i.e., the QR code faces upward).

[0111] S600: Place the material box 800 into the corresponding turnover box 900 according to the size of the material box 800, and transport the turnover box 900 into the warehouse by the feeding robot 700 after the turnover box 900 is full.

[0112] It should be noted that the numbering of the steps above does not indicate the order in which the steps are executed. As long as the steps are not logically related, the execution order of the steps can be adjusted appropriately.

[0113] In this embodiment, the packing and warehousing process of the material box 800 can be automatically completed according to its size and the type of device it contains. Furthermore, during the warehousing process of the material box 800 on the warehousing slip, returning material boxes and already stored material boxes can be queued for warehousing, resulting in a high degree of automation. In addition, if the material box 800 has a damaged, missing, or incorrectly scanned QR code, manual intervention can be performed before restarting the warehousing process, improving the fault tolerance of the automatic warehousing process.

[0114] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
