Detailed Implementation

[0060] The following will clearly and completely describe the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention. Furthermore, all connections / linkages mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0061] Reference Figures 1 to 11 A photovoltaic cell packaging production line is provided, comprising orthogonal Z, Y, and X directions. The Y and X directions are defined as two mutually perpendicular horizontal directions, and the Z direction is defined as a vertical direction. The X direction is the first direction, the Y direction is the second direction, and the Z direction is the third direction.

[0062] The photovoltaic cell packaging production line includes: main transport line 001 (represented by solid lines with arrows in the figure), return transport line 002 (represented by sparse dashed lines with arrows in the figure), NG transport line 003 (represented by dense dashed lines with arrows in the figure), and sampling transport line 004 (represented by dotted lines with arrows in the figure).

[0063] The main transport line 001 has a main transport path, along which are sequentially installed a battery cell feeding module 011, a first line changer 012, a second line changer 013, an auxiliary material feeding module 014, a third line changer 015, a packaging module 016, a fourth line changer 017, a plastic sealing module 018, and a packing module. The first line changer 012, the second line changer 013, the third line changer 015, and the fourth line changer 017 are all equipped with lifting machines. The end of the main transport line 001 connects to warehouse 021.

[0064] The return transport line 002 is located below the main transport line 001. The return transport line 002 has a return outflow end and a return inflow end. The return outflow end connects to the battery cell loading module 011. The return transport line 002 passes through the auxiliary material loading module 014. When the fixture transported by the return transport line 002 passes through the auxiliary material loading module 014, the auxiliary material loading module 014 places the auxiliary materials into the fixture.

[0065] It also includes an NG transport line 003 and a sampling transport line 004. The two ends of the NG transport line 003 are designated as NG inlet and NG outlet. The NG inlet connects to the return transport line 002 via a third line changer 015, and the NG outlet connects to the main transport line 001. The two ends of the sampling transport line 004 are designated as sampling inlet and sampling outlet. The sampling inlet connects to the return transport line 002 via a third line changer 015, and the sampling outlet connects to the main transport line 001.

[0066] The auxiliary material feeding module 014 includes three auxiliary material feeding components, which are arranged along the transport direction of the main transport line 001. Each auxiliary material feeding component includes an auxiliary material feeding rack 510, an auxiliary material X-axis drive device 520, an auxiliary material Z-axis drive device 530, a magazine feeding execution end 540, a magazine structure 550, a magazine lifting mechanism 560, and a magazine buffer conveyor line 570.

[0067] An auxiliary material X-axis drive device 520 is mounted on the auxiliary material loading rack 510. The auxiliary material X-axis drive device 520 is a linear drive device. An auxiliary material Z-axis drive device 530 is mounted on the output end of the auxiliary material X-axis drive device 520. The auxiliary material X-axis drive device 520 drives the auxiliary material Z-axis drive device 530 to move along the X direction. The auxiliary material Z-axis drive device 530 is also a linear drive device. The auxiliary material Z-axis drive device 530 drives the magazine loading execution end 540 to move along the Z direction. Specifically, in this embodiment, both the auxiliary material X-axis drive device 520 and the auxiliary material Z-axis drive device 530 are pneumatic linear drive devices. In other embodiments, the auxiliary material X-axis drive device 520 and the auxiliary material Z-axis drive device 530 can also be conventional linear drive devices such as electric or hydraulic linear drive devices. The magazine loading execution end 540 is mounted on the auxiliary material Z-axis drive device 530.

[0068] Multiple magazine structures 550 are used to accommodate different auxiliary materials. A magazine lifting mechanism 560 is used to lift the auxiliary materials located within the magazine structures 550, making it easier for the magazine loading actuator 540 to retrieve them. A magazine buffer conveyor line 570 is used to drive the magazine structures 550 to move in the X direction. Specifically, the magazine buffer conveyor line 570 is configured as a belt conveyor line, allowing the magazine structures 550 to move closer to or further away from the main transport line 001. When the magazine buffer conveyor line 570 is away from the main transport line 001, workers can easily replenish the auxiliary materials.

[0069] The packaging module 016 includes: a cell docking device 100, a straightening device 200, a bagging device 600, a boxing device 1500, a marking device 1600, and a cell clamping device 1200.

[0070] The cell clamping device 1200 has a clamping and transporting path that extends linearly along the Y direction. The cell docking device 100, straightening device 200, bagging device 600, boxing device 1500, and marking device 1600 are arranged sequentially beside the clamping and transporting path. The cell clamping device 1200 can transport the product from the straightening device 200 to the bagging device 600, the product from the bagging device 600 to the boxing device 1500, and the packaged box containing the product to the marking mechanism.

[0071] The battery cell gripping device 1200 includes a third moving component 1300 and a gripping component. The gripping component is used to grip the product or a package containing the product. The output end of the third moving component 1300 is connected to the gripping component to drive the gripping component to move along the gripping and transport path.

[0072] The battery cell clamping device 1200 includes two sets of clamping components. One set of clamping components is used to clamp the product to be packaged to the flip-top station, and the other set of clamping components is used to clamp the product that has been boxed to the next station. The third moving component 1300 is driven connected to the two sets of clamping components and can drive the two sets of clamping components to move synchronously in the left and right directions. The clamping assembly includes a clamp 1210, a clamping drive component 1220, and a third module 1230. The third moving component 1300 is the fourth module. The clamping drive component 1220 is driven to the clamp 1210, and drives the clamp 1210 to perform a clamping action. The third module 1230 is driven to the clamping drive component 1220, and drives the clamp 1210 and the clamping drive component 1220 to move in the front-back direction. The output end of the third moving component 1300 is connected to the third module 1230. The fourth module drives the third module 1230, the clamp 1210, and the clamping drive component 1220 to move in the left-right direction. The driving directions of the third module 1230 and the fourth module can be adjusted according to the actual production line layout, and are not specifically limited here.

[0073] When one set of gripping components grips the product to be packaged, the other set of gripping components grips the packaged product. Driven by the third moving component 1300, the gripping component gripping the product to be packaged moves to the flip-top station, while the gripping component gripping the packaged product moves to the next station. The synchronous movement of the two gripping components can greatly improve the packaging efficiency.

[0074] The cell docking device 100 includes a docking transport structure 110, a docking drive component 120, and a line-changing mechanism 130. The docking drive component 120 drives the docking transport structure 110, which in turn drives the cells to move along a regular transport direction (parallel to the X-direction). The docking transport structure 110 can be a roller conveyor, a chain conveyor, or other conveying structure, which will not be described in detail here. The docking drive component 120 is a rotary motor, and the docking transport structure 110 is a belt conveyor structure. There are two belt conveyor structures, spaced apart. The docking drive component 120 drives one of the pulleys to rotate, and the two belt conveyor structures transmit power through a relay shaft to achieve synchronous movement.

[0075] The line changing mechanism 130 includes: docking lifting drive 131 and docking lifting platform 132.

[0076] The docking lifting drive 131 is configured as a linear cylinder; specifically, it is a rodless cylinder, but it can also be configured as a conventional rod cylinder or an electric linear drive device. The line changing mechanism 130 has a second line docking end and a first line docking end. The second line docking end docks with the return transport line 002, and the first line docking end docks with the main transport line 001. The docking lifting platform 132 is fixedly installed at the output end of the docking lifting drive 131. The docking lifting platform 132 is driven by the docking lifting drive 131 to move up and down along the Z-direction, allowing its height to be adjusted.

[0077] The cell docking device 100 also includes a support lifting drive 141 and a support platform 142. The support lifting drive 141 is configured as a linear cylinder. The support platform 142 is fixedly connected to the output end of the support lifting drive 141, and the support platform 142 is driven by the support lifting drive 141 to move up and down in the Z direction. After the docking transport structure 110 docks the material box on the conveyor line, the docking lifting drive 131 drives the docking lifting platform 132 to rise, so that the docking lifting platform 132 and the components installed on the docking lifting platform 132 move upward. Then, the support lifting drive 141 drives the support platform 142 to move upward (in the initial state, the height of the support platform 142 is lower than the height of the upper end face of the docking transport structure 110), thereby driving the material box to rise.

[0078] The docking lifting drive 131, docking lifting platform 132, supporting lifting drive 141, and supporting platform 142 cooperate to raise the fixture, facilitating the orderly transport device 300 to grasp the battery cells. After the battery cells are grasped by the orderly transport device 300, the docking lifting drive 131 and supporting lifting drive 141 retract. When the height of the docking transport structure 110 is the same as the height of the external battery cell transport line, the docking drive 120 reverses, causing the fixture to return to the conveyor line.

[0079] The alignment device 200 is located on one side of the cell docking device 100 in the X direction. The alignment device 200 includes an alignment swing member 210 and an alignment swing drive member 220.

[0080] The oscillating member 210 has an oscillating placement slot 211. The oscillating member 210 is configured as a box-shaped structure, and the oscillating placement slot 211 is used to place the battery cells. The oscillating member 210 has a clearance slot 212 communicating with the oscillating placement slot 211. The clearance slot 212 is used to avoid obstruction, allowing the oscillating transport device 300 to smoothly remove the battery cells. There are two clearance slots 212, symmetrically arranged on both sides of the oscillating member 210 in the Y direction.

[0081] The regular swing drive 220 is configured as a rotary motor. The regular swing 210 is fixedly connected to the output end of the regular swing drive 220. The regular swing drive 220 drives the regular swing 210 to swing, so that the regular swing 210 swings around an axis parallel to the X direction.

[0082] During the oscillation of the aligning oscillator 210, the aligning oscillator 210 will align the solar cells so that the edges of multiple photovoltaic cells are aligned, thereby achieving automated alignment of solar cells, improving work efficiency, and reducing the breakage rate of solar cells and the risk of workers being scratched.

[0083] The feeding and straightening device 200 also includes a detection area, which is located on one side of the straightening swing member 210 in the Y direction. The detection mechanism 400 includes three detection cameras 410 (in other embodiments, defect detection equipment, scanners, etc., can be used instead of detection cameras 410 to achieve the same or similar function). The three detection cameras 410 are respectively located on one side of the detection area in the Z, Y, and X directions, with the detection ends of the detection cameras 410 facing the detection area. The three detection cameras 410 respectively detect different sides of the battery cells to determine whether the battery cells have been straightened.

[0084] The aligning and transporting device 300 includes an aligning and transporting gripper 310 and a multi-axis robot 320. The aligning and transporting gripper 310 is fixedly mounted on the actuator end of the multi-axis robot 320. The aligning and transporting device 300 has a second transport path and a first transport path. The first transport path extends from the cell docking device 100 to the aligning device 200, and is used to transport the cells from the cell docking device 100 to the aligning device 200. The second transport path extends from the aligning device 200 to the inspection area. The multi-axis robot 320 drives the aligning and transporting gripper 310 to move along the second and first transport paths, so that the aligning and transporting gripper 310 moves back and forth between the cell docking device 100, the aligning device 200, and the inspection area, thereby realizing the transport of the cells.

[0085] The aligning and transporting device 300 picks up the battery cell from the aligning device 200, and then transports the battery cell from the aligning device 200 to the inspection area along a second transport path. Next, two inspection cameras 410 on one side of the inspection area in the Y and X directions perform a first inspection of the battery cell. After the first inspection, the aligning and transporting device 300 drives the battery cell to rotate 180°, and the inspection camera 410 on one side of the inspection area in the X direction performs a second inspection of the battery cell on the other side in the X direction. Finally, the battery cell is gripped by the battery cell clamping device 1200, and then the inspection camera 410 on one side of the inspection area in the Z direction performs a final inspection of the battery cell. This ensures the alignment quality of the battery cells.

[0086] The packaging module 016 also includes a bagging device 600, a boxing device 1500, and a marking device 1600.

[0087] During the packaging of solar cells, manual bagging is required, followed by folding the bag opening 180 degrees, resulting in low production efficiency. The 600 bagging device is primarily designed to solve the technical problems associated with manual bagging.

[0088] The bagging device 600 includes a bag material box 611, a bag moving mechanism 612, a bagging suction cup 617, an opening support mechanism 615, and a bag flipping mechanism 616.

[0089] The bag moving mechanism 612 includes a bag-covering X-axis module 6121, a bag-covering Z-axis module 6122, and a bag-covering nozzle 6123. Both the bag-covering X-axis module 6121 and the bag-covering Z-axis module 6122 are equipped with electric linear drive devices. The bag-covering X-axis module 6121 is fixed in position. The bag-covering Z-axis module 6122 is fixed to the output end of the bag-covering X-axis module 6121, and the bag-covering X-axis module 6121 drives the bag-covering Z-axis module 6122 to move along the X-direction. The bag-covering nozzle 6123 is fixed to the output end of the bag-covering Z-axis module 6122, and the bag-covering Z-axis module 6122 drives the bag-covering nozzle 6123 to move along the Z-direction.

[0090] After the bagging X-axis module 6121 and the bagging Z-axis module 6122 place the cloth bag onto the bagging suction cup 617 through the bagging suction nozzle 6123, the bagging suction nozzle 6123 and the bagging suction cup 617 work together to open the bag opening. Then, the opening support mechanism 615 further expands both ends of the bag opening to facilitate the battery cell clamping device 1200 to place the battery cell into the bag.

[0091] The bag moving mechanism 612 picks up the bag and places it into the bag suction cup 617. The bag moving mechanism 612 and the bag suction cup 617 work together to open the bag opening. The battery cell clamping device 1200 puts the battery cells into the bag. Finally, the bag flipping mechanism 616 folds the bag over.

[0092] A lifting mechanism is provided below the bag material box 611. The lifting mechanism includes a motor, a lead screw, and a top plate. The motor drives the lead screw to rotate, and when the lead screw rotates, it causes the top plate to move vertically.

[0098] The flipping assembly 700 also includes a lid suction cup, which is fixed to the flip plate 710. When the packaging box moves to the flipping station, the lid suction cup adheres to the lid of the packaging box, thereby keeping the flip plate 710 connected to the lid. When the flip plate 710 flips upward, the lid also rotates accordingly, and the lid is not likely to detach from the flip plate 710 during the flipping process.

[0099] The flip assembly 700 also includes a limiting block 730, which forms an "L" shape with the flip plate 710. The limiting block 730 is used to restrict the position of the insertion block, preventing it from shifting during the flipping process and failing to be inserted into the inner cavity of the packaging box. The specific position of the limiting block 730 can be adjusted according to the packaging box.

[0100] The box-loading mechanism also includes a first moving component 820. The output end of the first moving component 820 is connected to the placement plate 810. The first moving component 820 drives the placement plate 810 to move in the X direction, causing the placement plate 810 to move closer to or away from the flipping component 700.

The output end of the second moving component 1000 is connected to the box-loading gripping component 900 to drive the box-loading gripping component 900 to move closer to or further away from the placement plate 810. The box-loading gripping component 900 is capable of gripping empty boxes. After the box-loading gripping component 900 grips a box, the second moving component 1000 drives the box-loading gripping component 900 to move to the placement plate 810 and place the box on the placement plate 810.

[0102] The second moving component 1000 includes a first module 1010 and a second module 1020. The second module 1020 can drive the first module 1010 and the box-grabbing component 900 to move along the Y direction, and the first module 1010 drives the box-grabbing component 900 to move along the vertical direction. The first module 1010 and the second module 1020 can be cylinders, electric cylinders, linear modules, etc.

[0103] The box-grabbing assembly 900 includes a clamping drive component 920 and a box-grabbing gripper 910. The output end of the first module 1010 is driven and connected to the clamping drive component 920, and the output end of the clamping drive component 920 is driven and connected to the box-grabbing gripper 910. The clamping drive component 920 drives the box-grabbing gripper 910 to clamp or release the box. The clamping drive component 920 drives the box-grabbing gripper 910 to hold the box, and the second moving component 1000 drives the box-grabbing gripper 910 and the box to move to the placement plate 810, realizing automatic feeding of the box. The clamping drive component 920 can be a cylinder, electric cylinder, etc., and the control of the box-grabbing gripper 910 is realized by pneumatic or electric motor driving belt movement.

[0104] The box-gripping assembly 900 also includes a clamping block 930 and a clamping drive component 940. The clamping drive component 940 is mounted on the output end of the first module 1010 and connected to the clamping drive component 920. The clamping drive component 940 can be a cylinder, electric cylinder, etc. The output end of the clamping drive component 940 is driven to move the clamping block 930 in the vertical direction.

[0105] After the packaging box gripper 910 grips the packaging box, the clamping drive component 940 drives the clamping block 930 to move towards the packaging box to clamp the packaging box and fix it in place, preventing the packaging box from tilting during movement and ensuring the accuracy of subsequent product placement.

[0106] In this embodiment, two clamping blocks 930 and two clamping drive components 940 are provided. The two clamping drive components 940 are used to drive the two clamping blocks 930 respectively. The two clamping blocks 930 are respectively provided on the left and right sides of the packaging box clamping claw 910. After the packaging box clamping claw 910 clamps the packaging box, it can clamp the left and right ends of the packaging box from above, ensuring the force balance on the left and right sides of the packaging box.

[0107] In some embodiments, the first feeding mechanism further includes a storage frame 1100, which is hollow to form a storage cavity with an upward opening. The storage cavity is used to hold packaging boxes, allowing them to be neatly arranged, which facilitates the gripping component 900 in gripping the boxes. In this embodiment, the storage frame 1100 is located at the left end of the second moving component 1000, while the moving platform 800 is located at the right end of the second moving component 1000. Under the driving action of the second moving component 1000, the gripping component 900 can move back and forth between the placement plate 810 of the moving platform 800 and the storage frame 1100 to achieve automatic feeding of packaging boxes.

[0108] The specific arrangement of the storage box 1100 and the moving platform 800 can be adjusted according to the actual situation of the production line. The second moving component 1000 can drive the box gripping component 900 to move back and forth between the storage box 1100 and the placement plate 810.

[0109] The first feeding mechanism also includes a fourth moving component. The output end of the fourth moving component is driven to connect to the storage box 1100 to lift the storage box 1100. Under the driving action of the fourth moving component, the storage box 1100 can move the packaging box vertically to move closer to or away from the second moving component 1000.

[0110] When the boxes are stacked, after the top box is picked up by the box gripping component 900, the position of the next box is lower than the original top box. The position of the box gripping component 900 driven by the second moving component 1000 is limited. Moreover, if the height of each box is different, the descent distance of the box gripping component 900 needs to be controlled each time it is picked up.

[0111] In this embodiment, the storage box 1100 is moved by the fourth moving component to feed the packaging box to the second moving component 1000. After the first packaging box is picked up, the fourth moving component drives other packaging boxes to fill the gap, which is beneficial for picking up the next packaging box.

[0112] The storage frame 1100 includes a frame body and a lifting plate. The lifting plate is located inside the frame body and is slidably connected to it. The frame body and the lifting plate together form a storage cavity for placing packaging boxes.

[0113] The box-loading device 1500 also includes two rows of rollers arranged along the Y direction to support the product. Each row of rollers has multiple rollers arranged along the X direction. A space is left between the two rows of rollers for the gripping component to move, facilitating its insertion into the flip-top station to grip the packaged product. The rollers are positioned between the flip-top station and the battery cell gripping device 1200. After the gripping component grips the product and places it on the rollers, it releases the product and pushes it into the packaging box at the flip-top station. The rollers allow the product to enter the inner cavity of the packaging box more smoothly.

[0114] The marking device 1600 is a marking machine. After the battery cell loading device 1500 performs the loading step, the marking device 1600 marks the packaging box.

[0115] Cache system 022 includes:

[0116] The cache shelf 2100 is equipped with multiple independent cache storage units 2110. The cache storage units 2110 are used to store goods to be packaged. Each cache storage unit 2110 is equipped with a position information.

[0117] It should be noted that the number, volume, and arrangement of the cache storage units 2110 of the cache shelf 2100 can be set according to the user's needs, and this embodiment does not impose specific restrictions.

[0118] It is worth noting that the grade information of each cache storage body 2110 is different. The grade information of the cache storage body 2110 is used to characterize the specific category of goods stored in the cache storage body 2110. The grade information of each cache storage body 2110 can be set according to the previously entered goods information. In addition, the cache shelf 2100 is also equipped with a retest cache storage body 2110. The retest cache storage body 2110 is used to store goods that do not match the grade information, thereby preventing goods without entered models from entering the production line, improving the accuracy of goods detection, and facilitating the subsequent processing of goods in the retest cache storage body 2110 by staff, such as retesting, adding new cache storage body 2110 information, or discarding goods, etc. This embodiment does not impose specific limitations.

[0119] The stacking mechanism 2200 is horizontally arranged on one side of the buffer rack 2100 along the length of the buffer rack 2100. The stacking mechanism 2200 is used to transport goods to be packaged in order to realize the transportation of goods to be packaged.

[0120] In some embodiments, the stacking mechanism 2200 includes one or more stacker cranes. When the stacking mechanism 2200 includes multiple stacker cranes, the multiple stacker cranes are arranged on both sides of the buffer rack 2100 along the length direction of the buffer rack 2100. By setting multiple stacker cranes, the transportation efficiency can be improved and the accumulation of goods can be avoided. In addition, multiple buffer racks 2100 can also be set. For example, the buffer racks 2100 and the stacking mechanism 2200 are arranged alternately so that a stacking mechanism 2200 is set on both sides of a buffer rack 2100, thereby improving the transportation efficiency of goods on the buffer rack 2100.

[0121] The buffer controller controls the detector to scan the barcode of each item to be packaged to determine its information, facilitating subsequent grading of different items. It compares the item information with the grade information to determine the target buffer storage 2110, thus grading the items and storing items of the same grade in the same buffer storage 2110. When the target buffer storage 2110 is not saturated, it controls the stacking mechanism 2200 to transport the items to be packaged to the target buffer storage 2110 for handling. Finally, when the items in the target buffer storage 2110 meet the preset packing conditions, it controls the stacking mechanism 2200 to remove all items from the target buffer storage 2110, thereby improving the efficiency of inbound and outbound operations and enabling the transportation of various types of goods.

[0122] In some embodiments, the detector can be a device equipped with a barcode scanner, barcode scanner, mobile terminal, or other device that has a barcode scanning module, thereby enabling the identification of the model of the goods to be packaged.

[0123] In some embodiments, the stacking mechanism 2200 includes a first stacker 2210, a second stacker 2220, a drive motor 2230, and a slide rail 2240. The first stacker 2210 and the second stacker 2220 are respectively disposed at both ends of the slide rail 2240. The drive motor 2230 is used to drive the first stacker 2210 and / or the second stacker 2220 to slide along the slide rail 2240, thereby realizing the transportation of goods to be packaged and improving the storage and retrieval efficiency of goods to be packaged.

[0124] It should be noted that the first stacker crane 2210 and the second stacker crane 2220 are used to grab the goods to be packed, place the goods to be packed, and move the goods to be packed, respectively. The first stacker crane 2210 and the second stacker crane 2220 work together to achieve high-efficiency transportation of the goods to be packed, and can avoid transportation interruption due to the failure of one stacker crane, thus saving time and costs.

[0125] It is worth noting that the drive motor 2230 can be a dual-actuator linear motor, a linear synchronous stepper motor, a linear induction motor, etc. In this embodiment, it is a dual-actuator linear motor to achieve high acceleration and high speed linear motion, which can reduce mechanical vibration and error accumulation, improve the stability and accuracy of the system, and the dual-actuator linear motor can provide sufficient thrust to meet the needs of most loads.

[0126] In some embodiments, the length of the slide rail 2240 is greater than the length of the buffer rack 2100, thereby enabling the retrieval of goods from any location in the buffer rack 2100, avoiding situations where the stacker crane cannot reach a certain location. Furthermore, a buffer position 2300 is provided at each end of the slide rail 2240, which is used to place the first stacker crane 2210 or the second stacker crane 2220, thereby enabling the storage of the stacker crane and preventing the two stacker cranes from colliding.

[0127] It is understandable that by setting buffer positions 2300 at both ends of the slide rail 2240, it can be ensured that when one stacker crane picks up or puts down materials, it is not affected by the other stacker crane, thereby achieving high-efficiency transportation of goods.

[0128] In some embodiments, when the stacker crane in the stacking mechanism 2200 transports the goods to be packaged to the target buffer warehouse 2110, firstly, the stacker crane closest to the goods to be packaged is calculated, and then the stacker crane is controlled to grab the goods to be packaged. While the stacker crane is moving the goods to be packaged, another idle stacker crane is controlled to move to the buffer position 2300, thereby avoiding collisions between the stacker crane and the idle stacker crane while the stacker crane is moving the goods to be packaged to the target warehouse position. Similarly, when it is necessary to retrieve the goods to be packaged from the warehouse position, firstly, the distance between the two stacker cranes and the warehouse position is calculated, the stacker crane closest to the warehouse position is selected to grab the goods, and another stacker crane is moved to the nearest buffer position 2300, thereby avoiding collisions between the two stacker cranes during the retrieval of the goods and ensuring efficient transportation of the goods.

[0129] It should be noted that when there are no goods to transport, the first stacker crane 2210 and the second stacker crane 2220 can be stored in the buffer positions 2300 at both ends of the slide rail 2240, which improves the aesthetics of the buffer system 022.

[0130] In some embodiments, the first stacker crane 2210 and the second stacker crane 2220 are respectively provided with a buffer gripping component 2410 and a lifting component 2420. The buffer gripping component 2410 is used to grip the goods to be packaged, and the lifting component 2420 is used to lift the goods to be packaged, thereby realizing the gripping and movement of the goods to be packaged.

[0131] It should be noted that the buffer gripping component 2410 can be a robotic arm, a vacuum suction cup, a clamp 1210, etc. The robotic arm can adjust the gripping force to grip the goods to be packaged, achieving flexible gripping; the vacuum suction cup can generate negative pressure to fix the goods on the suction cup surface, realizing gripping and handling operations; the clamp 1210 grips the goods by moving its upper and lower clamping plates. The lifting component 2420 can be a chain system, a screw lifting system, an elevator lifting system, etc., and this embodiment does not impose specific limitations.

[0132] In some embodiments, the buffer position 2300 is provided with a blocking member 2500, which is used to intercept the first stacker 2210 and / or the second stacker 2220, thereby preventing the first stacker 2210 or the second stacker 2220 from sliding out of the slide rail 2240, thus achieving the blocking of the first stacker 2210 and the second stacker 2220.

[0133] It should be noted that the blocking element 2500 is located on the outermost side of the buffer position 2300 to intercept the first stacker 2210 and the second stacker 2220. The blocking element 2500 can be a blocking block, a blocking groove, a blocking protrusion, etc., and this embodiment does not impose specific limitations.

[0134] It is understood that the blocking member 2500 can be integrated with the slide rail 2240 or can be movable relative to the slide rail 2240. This embodiment does not impose any specific restrictions.

[0135] Warehouse 021 comprises multiple storage units;

[0136] It should be noted that each warehouse can store different types of goods, and each warehouse is marked with a warehouse identifier, which is used to identify different types of warehouses.

[0137] The lifting mechanism 3200 is installed at both ends of warehouse 021. The lifting mechanism 3200 is used to transport the goods to be moved to the designated level, so that the goods can be transported to the designated level quickly and stably, reducing the time and labor intensity of manual handling, and effectively utilizing the space of warehouse 021 and production workshop.

[0138] It should be noted that the lifting mechanism 3200 can be a vertical lifting device, such as a hoist, elevator, etc. The hoist can be a hydraulic hoist, belt hoist, etc. This embodiment does not impose specific limitations.

[0139] Multiple transport units 3300 are used to transport goods to be moved to the warehouse, thereby improving the efficiency and productivity of goods transportation and saving labor costs.

[0140] It should be noted that the transport device 3300 can be a rail-guided vehicle, an automated guided vehicle, a logistics robot, etc.

[0141] The warehouse controller 3400 is used to acquire cargo information of goods to be moved, as well as the location information and working status of all transport devices 3300. It can determine in real time whether a transport device 3300 is currently moving goods, facilitating subsequent scheduling of the transport devices 3300. Based on the cargo information, it determines the hierarchical information and priority information of the goods to be moved, thereby accurately determining the usage frequency of the goods. Based on the priority information, it identifies the target storage space in warehouse 021 to realize the storage of goods. Furthermore, determining the target storage space through priority information improves the outbound efficiency of goods; that is, it can prioritize... Higher-level goods are placed on the side near the outbound end of the storage unit. Then, the level information is sent to the lifting mechanism 3200 so that the lifting mechanism 3200 can transport the goods to be moved to the designated level corresponding to the level information, thereby realizing the layered storage of goods and improving the management efficiency of goods. Finally, the target transport device 3300 for moving goods is determined according to the location information and the working device, and the target transport device 3300 is controlled to transport the goods to be moved to the target storage unit, thereby realizing the rational use of the transport device 3300, avoiding unnecessary detours of the transport device 3300, and improving the efficiency of goods transportation.
