Description

Technical Field

[0001] The present invention relates to the technical field of material storage and retrieval, and in particular to a material storage and retrieval device. Background Art

[0002] In modern industrial production, especially in areas requiring dense material storage, such as NdFeB material processing and electronic component manufacturing, the level of automation in storage equipment directly impacts production efficiency. Traditional storage equipment faces significant technical bottlenecks: First, the independent configuration of the equipment leads to poor integration with production lines, requiring the use of automated guided vehicle (AGV) carts to transfer pallets. For example, during the NdFeB processing process, material pallets must be transported back and forth to the storage equipment via an AGV, which can easily cause logistical congestion. Second, the material racks used to store pallets are fixed, requiring manual transfer or AGV carts to access each pallet individually. For example, a vertical automatic storage device disclosed in Chinese utility model patent CN 219504754U can only operate on a single shelf, and access must start from the bottom layer. When accessing the upper pallet, all the lower pallets must be removed first, and a single retrieval can take over 10 minutes.

[0003] Furthermore, existing multi-shelf systems face a capacity-cost conflict: adding independent storage units doubles the equipment investment cost; while expanding capacity with a single unit significantly reduces storage and retrieval efficiency. Furthermore, the connection between production lines and storage lacks an integrated design, forcing materials to undergo multiple transfers, increasing the risk of contamination and making production data traceability difficult. Therefore, there is an urgent need for intelligent storage equipment that can directly connect to production lines, provide efficient storage and retrieval, and flexibly expand storage capacity. Summary of the Invention

[0004] The present invention aims to solve the technical problems that the existing storage equipment cannot be connected to the production line, the material rack used to store the carrier tray cannot be transferred, and the storage and retrieval efficiency is low. In order to overcome the above defects of the existing technology, the present invention provides a material storage and retrieval equipment to realize automatic storage and retrieval of the carrier tray, which enables the production line to directly push the material into the carrier tray or directly push the material from the carrier tray into the production line. Direct docking with the production line eliminates the manual or AGV cart transfer and transportation links, and when all the carrier trays are full, the entire material rack can be directly transferred, solving the problem of fixed setting of the material rack. There is no need to transfer the carrier tray one by one. The overall transfer efficiency and storage and retrieval efficiency of the carrier tray are higher, ultimately improving the overall production efficiency.

[0005] For the purpose of the present invention, the following technical solutions are adopted: A material storage and retrieval device comprises a frame, a tray storage and retrieval device arranged on the frame, and a plurality of trays on the material frame that can move forward and backward; the frame has a first space and a second space that are connected and distributed along the front-to-back direction, the material frame is arranged in the first space and can be moved out of or into the first space, and the tray storage and retrieval device is arranged in the second space; the tray storage and retrieval device comprises a lifting frame and a push-pull mechanism arranged on the lifting frame; the push-pull mechanism is used to push the tray from the second space into the material frame or pull the tray from the material frame to the second space. The storage and retrieval equipment can realize automatic storage and retrieval of carriers, allowing the production line to directly push materials into the carrier or directly push materials from the carrier into the production line. It is directly connected to the production line, eliminating the need for manual or AGV cart transfer and transportation links, eliminating the AGV transfer link, and greatly improving the transportation efficiency. The lifting and positioning of the push-pull mechanism is achieved through the lifting frame, so that it can determine which layer of the carrier to be stored and accessed. After all the carriers are filled or sent out, the material rack can be directly moved out as a whole for replacement. There is no need to transfer and store each carrier separately. The storage and retrieval structure is more convenient and the storage and retrieval efficiency is higher, which ultimately improves the overall production efficiency of the product.

[0006] Preferably, the push-pull mechanism includes a support platform provided on a lifting frame, a first motor provided on the support platform, and a conveying member, wherein the first motor is used to drive the conveying member to move so as to move the carrier; alternatively, the push-pull mechanism includes a push-pull rod, and the push-pull rod is driven by a motor, an air cylinder, an oil cylinder, or a lead screw. Of course, the push-pull mechanism also includes conventional devices in the field and is not limited to the aforementioned structures. As long as the device is used to push the carrier from the second space into the material rack or to pull the carrier from the material rack to the second space, it falls within the scope of the push-pull mechanism. The support platform provides a horizontal load-bearing reference to prevent the carrier from tilting during movement, and the cooperation of the first motor and the conveying member enables horizontal access, thereby improving the convenience of access.

[0007] Preferably, the conveyor member is a conveyor chain or a conveyor belt; the conveyor member is provided with a first protrusion for driving the carrier to move, and the carrier is provided with a slot, and the first protrusion can slide into or out of the slot. By the first protrusion on the conveyor member being able to cooperate with the slot on the carrier, the carrier can be driven to move and prevented from falling off during movement, thereby achieving an effect of convenient storage and retrieval.

[0008] Preferably, the conveyor is further provided with a second protrusion for pushing the carrier into the material rack, with the second protrusion positioned behind the first protrusion in the pushing direction. The second protrusion allows the carrier to be pushed into the material rack and then precisely positioned again, ensuring that the carrier is accurately positioned within the material rack, thereby resolving the problem of inaccurate positioning, improving the degree of automation, and ensuring accurate positioning.

[0009] Preferably, the frame is provided with a locking device for locking the material rack and the frame. The locking device clamps the material rack, further achieving clamping stability and preventing the material rack from shifting during storage and retrieval.

[0010] Preferably, the locking device includes two clamping parts and a clamping drive. The clamping drive is used to drive the two clamping parts toward or away from each other to clamp and release the locking block on the material rack. The locking device clamps the locking block on the material rack, preventing the material rack from shifting during storage and retrieval. The clamping drive and the two clamping parts cooperate to further ensure clamping stability. Furthermore, the movable material rack allows a single device to precisely dock multiple material racks, thereby increasing storage capacity and convenience.

[0011] Preferably, the clamping drive part includes a third motor, a screw, a first clamping slide, and a second clamping slide; the screw is connected to the third motor, and the first clamping slide and the second clamping slide are both coordinated with the screw transmission, and the first clamping slide and the second clamping slide are moved closer to or away from each other; the clamping parts on both sides include a first clamping plate and a second clamping plate; one end of the first clamping plate is hinged to the rotating shaft seat, and the other end of the first clamping plate is used to clamp the locking block; one end of the second clamping plate is hinged to the clamping slide on the corresponding side, and the other end of the second clamping plate is hinged to the middle of the first clamping plate, and the clamping and release of the first clamping plate are achieved by the back-and-forth horizontal movement of the clamping slide. The clamping drive unit uses a motor to drive the screw rod, which drives the clamping slide through the positive and negative threads, and the clamping plate is linked to clamp the locking block, replacing manual positioning, shortening the time-consuming clamping process, and the clamping force is uniform, ensuring that the material rack has no displacement, improving the convenience and stability of the material rack clamping, and also facilitating the transfer and fixation of the material rack, improving the flexibility of the material rack transportation and replacement, and the positive and negative thread design realizes synchronous symmetrical clamping. Compared with the pneumatic clamping method, it is not affected by air pressure fluctuations and the failure rate is reduced.

[0012] Preferably, the system also includes a material feeding device, comprising a loading drive and a loading push plate connected thereto, for feeding materials into a loading tray located within the second space. By directly receiving materials from the production line, the material feeding device feeds materials row by row, replacing manual or AGV transport, significantly improving production efficiency.

[0013] Preferably, the system further includes a material discharging device comprising a material discharging drive mechanism and a material discharging push plate mounted on the material discharging drive mechanism. The material discharging drive mechanism drives the material discharging push plate to displace material from the carrier plate within the second space. The material discharging push plate on the material discharging drive mechanism displaces the material horizontally onto the production line, where it interfaces with the production line, significantly improving production efficiency.

[0014] The material discharging device is preferably further provided with a material discharging lifting mechanism synchronized with the material discharging drive mechanism; the material discharging lifting mechanism is used to drive the material discharging push plate up and down. The material discharging lifting mechanism and the material discharging drive mechanism can adjust the height and horizontal push plate to adapt to different levels of the material rack, thereby improving flexibility compared to fixed-height discharging structures.

[0015] In summary, the present invention effectively solves the pain points of traditional storage equipment through multi-dimensional technological innovation and achieves the following technical effects: It can realize automatic storage and retrieval of the carrier plate.

[0016] Production line docking and efficient transportation: The production line can be directly docked with the tray storage and retrieval device in the second space of the rack. The production line can directly push materials into the tray or materials can be pushed out from the material rack into the production line; the material rack is equipped with multiple trays spaced up and down. The tray storage and retrieval device can automatically select the tray and store it in the material rack through horizontal transportation after the tray is full, eliminating the AGV transfer link, greatly improving material transportation efficiency and significantly reducing logistics costs.

[0017] Flexible access and precise positioning: The push-pull mechanism, combined with the lifting frame, can directly access the carrier at any height of the material rack horizontally without the need for bottom turnover. The first and second bumps on the conveyor chain of the conveyor are designed to ensure the accuracy of the carrier positioning.

[0018] Storage expansion and cost optimization: The locking device enables a single device to switch between multiple material racks, greatly improving storage flexibility. The overall transfer design of the material rack further reduces the number of times the carrier is moved, reduces the breakage rate of material flow, and further reduces the scrap rate.

[0019] Improved automation and reliability: The material conveying device and locking device are fully automated, reducing manual intervention; accuracy and reliability are improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of the present application and are not intended to limit the scope of protection of the embodiments of the present application. Those skilled in the art may adjust them as needed to suit specific application scenarios.

[0038] In the description of the embodiments of this application, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on the specific circumstances.

[0039] In the embodiments of the present application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, a first feature being "above," "above," and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0040] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] like Figures 1 to 16 As shown, a material storage and retrieval device includes a frame 1, a tray storage and retrieval device 3 disposed on the frame 1, a material rack 5, trays 4 disposed on the material rack 5 at equal intervals and movable forward and backward, and a material conveying device, the material conveying device including a material feeding device for loading and a material discharging device for unloading. The frame 1 has a first space 11 and a second space 12 that are connected and distributed along the front-to-back direction. In other words, the front-to-back movement direction of the tray 4 is compatible with the front-to-back distribution positions of the first space 11 and the second space 12. The first space 11 is a U-shaped space disposed at the rear side of the frame 1 and opening toward the rear, and the second space 12 is a U-shaped space disposed at the front side of the frame 1 and opening toward the front, and the two U-shaped spaces are connected. The material rack 5 is disposed in the first space 11 and can be moved horizontally forward and backward into or out of the first space 11 on the frame 1. The tray access device 3 is disposed in the second space 12. The tray access device 3 includes a lifting frame 32 and a push-pull mechanism 31 mounted on the lifting frame 32. When the material conveying device is used to deliver materials to or from the tray 4, the push-pull mechanism 31 is used to push the tray 4 horizontally into or out of the material rack 5. The material conveying device and the tray access device 3 can be integrated together, allowing the material to be directly pushed into or out of the tray 4 via the material conveying device, eliminating the AGV transfer link and greatly improving transportation efficiency. The lifting frame 32 enables the push-pull mechanism 31 to be raised and lowered, thereby determining the tray 4 to be accessed at a specific level. Once all trays 4 are filled or removed, the material rack 5 can be directly removed for replacement, eliminating the need for individual trays 4 to be transferred and stored. This makes the access structure more convenient and efficient, ultimately improving overall product production efficiency.

[0042] like Figure 10 and Figure 12As shown, each carrier plate 4 is horizontally slidably fitted on the material rack 5 in the front-to-back direction. The material rack 5 is a rectangular frame that penetrates the front-to-back direction. The front side of the material rack 5 is used to push the carrier plate 4 in and out. A vertical stop bar is provided in the middle of the rear side of the material rack 5 to limit the carrier plate 4 and prevent the carrier plate 4 from being pushed out of the material rack 5. Four wheels are provided on the four corners of the bottom of the material rack 5, so that it can be transferred manually or by an AGV trolley, thereby enabling the replacement and transportation of the entire material rack 5, further improving the transportation efficiency and convenience. The left and right sides of the material rack 5 are symmetrically provided with material rack partitions 52 that are evenly spaced from top to bottom, and the two material rack partitions 52 are used to support the left and right sides of the bottom surface of the carrier plate 4, and each material rack partition 52 is provided with a number of horizontally rotating material rack guide wheels 53 that are evenly spaced along the front-to-back direction. In this embodiment, the number of material rack guide wheels 53 is three. A carrier plate 4 can be placed on each layer of the material rack partition 52 of the material rack 5. The carrier plate 4 is as shown in FIG. Figure 1 and Figure 10 As shown, the top surface of the carrier tray 4 is a horizontal, flat surface, with a number of horizontally distributed placement partitions 43 arranged at equal intervals along the front-to-back direction. Rows of materials are pushed into the gap between the two placement partitions 43 by a material conveying device. Snap-in positioning blocks 42 are symmetrically provided on the center left and center right sides of the carrier tray 4. The bottom surfaces of the snap-in positioning blocks 42 are provided with downward-opening, rectangular slots 41. These slots cooperate with the push-pull mechanism 31 to enable the carrier tray 4 to be moved in or out horizontally. Several carrier rollers 44 are spaced apart along the front-to-back direction on the left and right sides of the carrier tray 4. In this embodiment, there are three carrier rollers 44. When the carrier rollers 44 are pushed into the material rack 5, they can roll on the placement partitions 43, thereby ensuring smooth and stable insertion into the material rack 5 and further ensuring positioning accuracy.

[0043] In this embodiment, the material feeding device can be implemented in multiple ways: The first method is to use a common conveying robot located between two devices to deliver the materials one by one to the carrier 4.

The feeding mechanism 22 of the embodiment comprises a feeding driving frame 221 and a feeding driving part 222; the feeding driving frame 221 is arranged on the feeding support 211, and the feeding driving part 222 can be in the transmission mode of an electric cylinder, an air cylinder, an oil cylinder or a motor lead screw. In the embodiment, the feeding driving part 222 is a conveying horizontal driving electric cylinder, and can also be in the form of an air cylinder or an oil cylinder to realize horizontal driving positioning. The fixed part of the feeding driving part 222 is arranged on the feeding driving frame 221 in the horizontal direction, the feeding push plate 23 is above the connection table top, the feeding push plate 23 is connected to the driving part of the feeding driving part 222, and the feeding push plate 23 is provided with a feeding sliding rail 24 between the feeding driving frame 221. The material output by the production line is directly connected by the connection flat plate 212 on the feeding connection platform 21, the feeding push plate 23 pushes the material on the connection flat plate 212 row by row, and the manual or AGV trolley conveying is replaced, so that the production efficiency is greatly improved. At the same time, the material output is directly connected to the storage equipment, so that the whole production line is connected, and a good foundation is provided for the subsequent whole automatic production line.

The blanking drive mechanism 72 of this embodiment includes a blanking horizontal slide 721, a fourth motor 722, a blanking drive gear 723, and a blanking rack 724; the blanking horizontal slide 721 is slidably connected to the blanking support plate 71 through two upper and lower blanking horizontal slide rails 725; the fourth motor 722 is set on the blanking horizontal slide 721, the blanking drive gear 723 is connected to the drive shaft of the fourth motor 722, and the blanking rack 724 is set on the blanking support plate 71 in the left and right horizontal directions, and the blanking drive gear 723 is meshed with the blanking rack 724. The horizontal movement and positioning of the material on the material rack 724 is achieved by the rotation of the material driving gear 723. The material lifting mechanism 73 can adopt the transmission mode of electric cylinder, pneumatic cylinder, or motor screw. In this embodiment, the material lifting mechanism 73 includes a material lifting cylinder 731 and a material lifting slide 732. The cylinder body of the material lifting cylinder 731 is vertically arranged on the material horizontal slide 721. The telescopic rod of the material lifting cylinder 731 is connected to the material pushing plate 74, and the material pushing plate 74 is slidably connected to the material horizontal slide 721 via the material lifting slide 732. The height and horizontal push-out or push-in position of the material pushing plate 74 can be adjusted by the material driving mechanism 72 and the material lifting mechanism 73 to adapt to different layers of the material rack 5. Compared with the fixed height discharge structure, the flexibility is improved.

[0046] In a complete production line, a material feeding device is generally set up to realize material feeding, and a material discharging device is also set up to realize material discharging.

[0047] like Figure 3 and Figure 4As shown, the lifting frame 32 has a lifting positioning plate 321, a first lifting rail assembly 322, a second lifting rail assembly 323, and a lifting drive positioning assembly 324, which cooperate to enable the lifting positioning plate 321 to rise or fall on the frame 1; the lifting positioning plate 321 is slidably connected to the left side of the frame 1 through the first lifting rail assembly 322, and the lifting positioning plate 321 is slidably connected to the right side of the frame 1 through the second lifting rail assembly 323; the lifting drive positioning assembly 324 is arranged on the lifting positioning plate 321, and drives the lifting positioning plate 321 to achieve lifting and positioning through the lifting drive positioning assembly 324; the first lifting rail assembly 322 and the second lifting rail assembly 323 both include The slide rail support plate 3221 and the vertical slide rail 3222; the vertical slide rail 3222 is vertically arranged on the front frame rod of the frame 1 through the slide rail support plate 3221, and the lifting positioning plate 321 is slidably fitted on the vertical slide rail 3222 through a number of sliders; the lifting drive positioning assembly 324 includes a second motor 3241, a lifting active synchronous wheel 3242, a first synchronous wheel 3243, a first rack 3244, a lifting driven synchronous wheel 3245, a second synchronous wheel 3246, a second rack 3247 and a lifting synchronous chain 3248; the lifting active synchronous wheel 3242, the first synchronous wheel 3243, the lifting driven synchronous wheel 3245, and the second synchronous wheel 3246 are all gears. The second motor 3241 is arranged on the left side of the lifting positioning plate 321. The second motor 3241 is arranged in the front-to-back direction. The output shaft of the second motor 3241 passes through the lifting positioning plate 321 backward, and the output shaft of the second motor 3241 is rotatably connected to the lifting positioning plate 321 through a bearing. The lifting active synchronous wheel 3242 and the first synchronous wheel 3243 are coaxially arranged on the output shaft of the second motor 3241. The lifting driven synchronous wheel 3245 and the second synchronous wheel 3246 are coaxially arranged through the connecting shaft 3249 and rotatably connected to the right side of the lifting positioning plate 321. The lifting driven synchronous wheel 3245 and the lifting active synchronous wheel 3242 are horizontally aligned left and right, and the first synchronous wheel 3243 and the second synchronous wheel 3246 are horizontally aligned left and right. The first rack 3244 and the second rack 3247 are vertically arranged on the left and right sides of the frame 1, respectively. The lifting active synchronous wheel 3242 meshes with the first rack 3244, and the lifting driven synchronous wheel 3245 meshes with the second rack 3247.

The conveyor 313 in the figure is a conveyor chain. The support platform 310 provides a horizontal load base to prevent the carrier 4 from tilting during movement. The access drive unit enables horizontal access, improving access convenience.

[0049] like Figure 4 and Figure 5 As shown, the conveying members 313 of this embodiment are symmetrically arranged on the left and right sides of the support platform 310. In this embodiment, the first motor 318 is a dual-axis motor, and the two output ends of the dual-axis motor are coaxially arranged on the left and right sides of the dual-axis motor. The two output ends of the dual-axis motor are respectively connected to the conveying members 313 on both sides; to drive the conveying members 313, a storage and retrieval driving wheel 311 and a storage and retrieval driven wheel 312 are also included; the storage and retrieval driving wheel 311 is connected to the output end of one side of the first motor 318, and the storage and retrieval driven wheel 312 is rotationally connected to the support platform 310 via a gear shaft. The storage and retrieval driven wheel 312 and the storage and retrieval driving wheel 311 are located on the front and rear sides of the support platform 310 and are horizontally aligned; the conveying chain is tensioned and connected to the storage and retrieval driven wheel 312 and the storage and retrieval driving wheel 311, and the conveying chain is provided with an access drive unit for driving the carrier 4; the conveying chain is provided with an access positioning unit for pushing the carrier 4 into the material rack 5. The conveying member 313 can also be in the form of a conventional conveyor belt, conveyor plate, or gear rack to achieve transportation. The synchronous drive on both sides prevents the carrier 4 from being biased by one side. The access drive unit on the conveyor chain can drive the carrier 4 to move horizontally. The access positioning unit can push the carrier 4 into the material rack 5 and then accurately position it again to ensure that the carrier 4 is accurately positioned in the material rack 5.

[0050] like Figures 6 to 9As shown, in this embodiment, the access drive portion is composed of two first protrusions 314 arranged in parallel on the lateral inner side of the conveyor chain. The first protrusions 314 are horizontally protruding drive columns. The two first protrusions 314 are respectively arranged on the right chain pin of one chain plate and the left chain pin of the next adjacent chain plate. A slot 41 is provided at the bottom of the carrier 4, which is engaged with the first protrusion 314 and has a downward U-shaped opening. When the first protrusion 314 is located in the slot 41, the rotation of the conveyor chain can drive the carrier 4 to move horizontally to be pushed in or out. The access positioning portion includes a second protrusion 315 provided on the lateral inner side of the conveyor chain. The second protrusion 315 is a horizontally protruding positioning column. The second protrusions 315 are spaced apart on the side (front) of the first protrusion 314 away from the material rack 5. The second protrusions 315 cooperate with the latching and positioning blocks 42 on the front of the carrier 4. When the first protrusions 314 push the carrier 4 horizontally into the material rack 5 (at the corner 3131 of the conveyor), and after the first protrusions 314 are rotated out of the latching slot 41 at the corner 3131 of the conveyor, the two first protrusions 314 are respectively positioned on two adjacent chain plates, thereby ensuring that the two first protrusions 314 are sequentially disengaged from the latching slot 41, preventing them from getting stuck at the corner 3131 of the conveyor, thereby ensuring smooth insertion or removal. After the first protrusions 314 are completely out of the latching slot 41, the second protrusions 315 finally push the carrier 4 completely into the material rack 5 and position it. Access guide wheel groups are provided on both sides of the support platform 310 to cooperate with the bottom surface of the carrier 4; each access guide wheel group includes three first access guide wheels 316 that are spaced apart in the front-to-back direction and rotate horizontally, and three second access guide wheels 317 that are spaced apart in the front-to-back direction and rotate vertically. A downward-opening U-shaped moving slide 45 is provided on the left and right sides of the bottom surface of the carrier 4 corresponding to the access guide wheel positions, and the moving slide 45 is set to penetrate in the front-to-back direction. The first access guide wheel 316 slides with the two side walls of the moving slide 45, and the second access guide wheel 317 slides with the bottom of the moving slide 45. The first access guide wheel 316 and the second access guide wheel 317 can further ensure the smoothness, stability and accuracy of the movement of the carrier 4 on the support platform 310. By snapping the first protrusion 314 into the slot 41, the carrier plate 4 can be driven to move to prevent it from falling off during movement, and the second protrusion 315 can push the carrier plate 4 to position it after it reaches the material rack 5, solving the problem of inaccurate positioning, improving the degree of automation, and ensuring the accuracy of positioning.

[0051] like Figure 2 and Figure 11As shown, the locking device 6 for locking the material rack 5 and the rack 1 can be a locking slot and locking block structure arranged on the material rack 5 and the rack 1, or can be achieved by a lock to fix the material rack 5 and the rack 1. In this embodiment, the material rack 5 is provided with a locking block 51 matched with the locking device 6, and the locking block 51 is a rotating connection on the bottom of the material rack 5, and the two locking guide wheels are horizontally rotating, and the two locking guide wheels are parallel and spaced apart along the left and right directions, and the locking device 6 includes a locking base 61, clamping portions 62 arranged on both sides of the locking base 61, and clamping driving portions 63, and the clamping driving portions 63 are used to drive the two clamping portions 62 to approach or move away from each other, so as to realize the clamping and loosening of the two locking blocks 51 on the material rack 5. By clamping the locking block 51 on the material rack 5 through the locking device 6, the displacement of the material rack 5 during storage and retrieval is prevented, and by the cooperation of the clamping driving portions 63 and the two clamping portions 62, the stability of clamping is further realized, and by the movable material rack 5, the precise docking of a single device to multiple material racks 5 is realized, the storage capacity and the convenience of storage are improved.

[0052] As Figure 11As shown, the clamping drive part 63 includes a third motor 631, a lead screw 632, a first clamping slide 633, and a second clamping slide 634; the third motor 631 is arranged on the locking base 61, the lead screw 632 is arranged horizontally left and right, and both ends of the lead screw 632 are rotatably connected to the locking base 61 through a rotating shaft seat 635, and the left end of the lead screw 632 passes through the rotating shaft seat 635 and is connected to the third motor 631, the first clamping slide 633 and the second clamping slide 634 are both slidably connected to the locking base 61 through a clamping movable slide rail 636, and the first clamping slide 633 and the second clamping slide 634 are both threadedly rotated with the lead screw 632; the thread directions of the first clamping slide 633 and the second clamping slide 634 are opposite, and the first clamping slide 633 and the second clamping slide 634 are able to approach or move away from each other. The clamping parts 62 on both sides include a first clamping plate 621 and a second clamping plate 622; the inner end of the first clamping plate 621 is hinged on the rotating shaft seat 635, and the outer end of the first clamping plate 621 is used to clamp the locking block 51; the inner end of the second clamping plate 622 is hinged on the clamping slide on the corresponding side, and the outer end of the second clamping plate 622 is hinged to the middle of the first clamping plate 621. The clamping and loosening of the first clamping plate 621 are achieved by the back-and-forth horizontal movement of the clamping slide, thereby achieving the two locking blocks 51 on the material rack 5 to be clamped and centered, without the need for manual positioning or AGV trolley positioning. The positioning is more convenient and more accurate, and it also cooperates with the replacement of the material rack 5. The clamping drive part 63 adopts a motor to drive the rotating shaft, and the positive and negative threads drive the clamping slide, which links the clamping plate to clamp the locking block 51, replacing manual positioning, shortening the time of the clamping process, and the clamping force is uniform, ensuring that the material rack 5 has no displacement, improving the convenience and stability of the clamping of the material rack 5, and facilitating the transfer and fixation of the material rack 5, improving the flexibility of the material rack 5 in conveying and replacing, and the positive and negative thread design realizes synchronous symmetrical clamping. Compared with the pneumatic clamping method, it is not affected by air pressure fluctuations and the failure rate is reduced.

[0053] In the loading and storage process of this embodiment: first, the material rack 5 filled with the carrier tray 4 (empty) is pushed into the first space 11 at the rear of the frame 1, and the clamping drive part 63 on the locking device 6 drives the two clamping parts 62 to move closer to each other to hold the locking block 51 on the material rack 5 tightly, so that the material rack 5 is fixed in the center of the frame 1, and the lifting drive positioning assembly 324 on the lifting frame 32 drives the lifting positioning plate 321 to be lifted to a specified layer, and the first protrusion 314 in the conveying chain on the push-pull mechanism 31 is inserted from the back to the front into the card slot 41 at the front of the carrier tray 4, and the conveying chain continues to move, so that the carrier tray 4 moves forward together with the conveying chain, and the empty carrier tray 4 is moved into the second space 12 At the loading position, the material is transported from the production line to the loading connection platform 21, and the material is horizontally aligned in the left and right directions. The loading mechanism 22 on the material feeding device drives the loading push plate 23 to push a row of materials horizontally into a row of gaps in the carrier 4. After the entire carrier 4 is filled, the carrier 4 is pushed into the material rack 5 by moving the conveyor chain backward, and after rotating out of the card slot 41 at the corner of the conveyor 3131, the carrier 4 is finally pushed completely into the material rack 5 by the second protrusion 315 to complete the storage of one tray 4. The above actions are repeated until the carriers 4 on the entire material rack 5 are filled with materials, and the entire material rack 5 is moved out and transferred to other stations for processing.

[0054] In the process of unloading and taking out materials in this embodiment: the material rack 5 filled with the loading tray 4 (filled with materials) is pushed into the first space 11 at the rear of the frame 1, and the two clamping parts 62 are driven to move closer to each other by the clamping driving part 63 on the locking device 6 to hold the locking block 51 on the material rack 5 tightly, so that the material rack 5 is fixed in the center of the first space 11 of the frame 1, and the lifting driving positioning component 324 on the lifting frame 32 drives the lifting positioning plate 321 to be lifted to a specified layer, and the first protrusion 314 in the conveying chain on the push-pull mechanism 31 is clamped from back to front into the card slot 41 at the front of the loading tray 4, and the conveying chain continues to move, so that the loading tray 4 moves forward together with the conveying chain, and the loading tray 4 filled with materials is moved to the unloading position of the second space 12, and then The horizontal unloading slide 721 is positioned above the carrier 4 through the cooperation of the unloading drive gear 723 and the unloading rack 724, and the unloading lifting cylinder 731 drives the unloading push plate 74 to descend, and under the action of the unloading drive mechanism 72, the material is pushed horizontally out of the carrier 4 and enters the next process. After each row of materials on the carrier 4 is pushed out, the empty carrier 4 is pushed into the material rack 5 by moving backward through the conveyor chain, and rotates out of the card slot 41 at the corner of the conveyor 3131, and finally, the empty carrier 4 is completely pushed into the material rack 5 by the second protrusion 315 on the conveyor chain, completing the unloading of one plate of carrier 4, and repeating the above actions until all the materials in the carrier 4 on the entire material rack 5 are unloaded, and the entire material rack 5 is removed and replaced.

[0055] When the trays 4 on the material rack 5 include both empty trays 4 and trays 4 loaded with materials, the material conveying device on the equipment in this embodiment can switch back and forth between loading and unloading materials, thereby achieving flexibility and convenience in storage and retrieval.

[0056] The technical advantages of the present invention include: The frame 1 has a first space 11 and a second space 12 that are connected to each other. The material rack 5 and the tray storage and retrieval device are located in the first space 11 and the second space 12 respectively. The material rack 5 together with the tray placed thereon can be moved out of or into the first space 11 as a whole. Therefore, automatic retrieval of the tray and overall transportation of the tray can be realized, greatly improving the efficiency of tray storage and transportation.

[0057] Eliminate AGV transfer links: Through the integrated design of the material conveying device and the carrier tray access device 3, the production line can directly push the material into the carrier tray 4 without the need for AGV cart transfer, reducing the risk of logistics congestion, improving transportation efficiency, and reducing logistics costs.

[0058] Horizontal storage and retrieval simplifies the process: After the loading tray 4 is full, it can be directly stored horizontally in the material rack 5 without the need for lifting and lowering, avoiding the tedious process of "lifting and lowering for storage and retrieval" of traditional equipment.

[0059] Synchronous drive and precise positioning: The horizontal storage and retrieval units on the left and right sides are driven by a conveyor chain. The first protrusion 314 engages with the slot 41 of the carrier plate 4 to drive the carrier plate 4 to move. The second protrusion 315 pushes the carrier plate 4 to position it after it reaches the material rack 5, achieving precise positioning. This solves the problem of inaccurate traditional manual positioning and reduces the material damage rate.

[0060] Guide wheel group and double slide rail design: The support platform 310 is equipped with horizontal and vertical guide wheel groups to reduce the movement resistance of the carrier 4; the lifting frame 32 is driven by double slide rails and a conveyor chain to improve structural stability.

[0061] Multi-rack switching and capacity expansion: The locking device 6 automatically positions the material rack 5 through the clamping drive unit 63. A single device can switch between multiple material racks 5, solving the pain point of "capacity and cost contradiction" in multi-rack systems.

[0062] Overall transfer and efficient turnover: Wheels are set at the bottom of the material rack 5, which can be transferred as a whole. Cooperating with the locking device 6, it can realize quick replacement and reduce the number of times the carrier 4 is moved.

[0063] Feeding-storage-discharging closed loop: A material conveying device is added, and the position of the push plate is adjusted by the horizontal and lifting drive mechanism to realize the automatic removal of materials from the carrier plate 4, forming a full-process automated closed loop.

[0064] Precise positioning: The first protrusion 314 and the second protrusion 315 on the inner side of the conveyor chain are spaced apart. The first protrusion 314 drives the carrier 4 to move, and the second protrusion 315 disengages from the slot 41 at the corner and pushes it into position, preventing the carrier 4 from falling off and ensuring a smooth access process.

[0065] Precise clamping of the material rack: The clamping drive unit 63 drives the lead screw 632 through the motor, and the positive and negative threads drive the clamping slide, which in turn clamps the clamping plate to clamp the locking block 51 of the material rack. The clamping force is uniform, which prevents the rack from shifting during storage and retrieval, and significantly improves safety.

[0066] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
