[0002] Material handling mainly refers to the mechanical equipment used within an enterprise for loading, unloading, transporting, lifting, stacking, and storing materials. It generally includes lifting machinery, conveyors, loading and unloading machinery, handling vehicles, and warehousing equipment. In daily life, some simple and lightweight material handling machinery is also frequently used, such as various handcarts and grippers.

[0003] With the development of technology, mechanical material handling has gradually replaced manual handling. Currently, material handling is generally done by placing the material directly onto a conveyor belt and then transporting it. However, some materials need to be scanned during transport so that warehouse staff can easily track them. But during transport, some materials cannot be scanned due to improper placement, requiring manual inspection and scanning, which increases the workload of manual labor, thereby reducing material handling efficiency and increasing labor costs.

[0016] Preferably, the top of the fixing seat has a limiting groove and is movably connected to the mounting column.

[0017] This application also proposes a method for using an intelligent material handling device, the steps of which are as follows:

[0018] S1. The staff starts the drive motor, which drives the connecting shaft, the first transmission belt and the second transmission belt to rotate. The first transmission belt drives the first connecting piece to rotate. The rotation of the first connecting piece drives the gear to rotate. The rotation of the gear drives the two sets of racks to move. The movement of the two sets of racks drives the mounting piece and the mounting block to move. The movement of the mounting block drives the clamping piece and the mounting rod to move. The mounting rod slides in the fixed rod, thereby clamping the material.

[0019] S2. After clamping, the connecting shaft drives the clamping module to rotate. The clamping module rotates 180 degrees to the upper end of the conveying unit. Then, the drive motor drives the connecting shaft to rotate in the opposite direction. When rotating, the gear drives the rack to move. The rack moves so that the material falls from between the two sets of clamping parts to the surface of the conveying unit.

[0020] S3. After the material falls, the conveying unit continues to convey the material. At the same time, the second transmission belt drives the second connecting piece to rotate, the second connecting piece drives the third transmission belt to rotate, the second connecting piece drives the rectangular plate to rotate, the rectangular plate drives the two sets of moving parts to rotate, the two sets of moving parts drive the two sets of mounting columns and moving plates to move, and the two moving plates to move, thereby organizing the material that has fallen onto the surface of the conveying unit.

[0021] S4. After the materials are sorted, the conveying unit continuously transports the materials, allowing subsequent scanning instruments to scan them. This facilitates the inventory management by warehouse personnel, thereby reducing manual workload and labor costs and improving the efficiency of material conveying.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] This invention achieves the effect of organizing materials through the combination of structures such as movable plates and fixed blocks. Simultaneously, a second transmission belt drives a second connecting member to rotate, which in turn drives a third transmission belt to rotate. The second connecting member then drives a rectangular plate to rotate, which in turn drives two sets of movable parts to rotate. These two sets of movable parts then move two sets of mounting columns and movable plates, thus organizing the materials falling onto the surface of the conveying unit. This allows subsequent scanning equipment to scan the materials, facilitating inventory management by warehouse personnel. This reduces manual workload and labor costs, and improves material conveying efficiency.

[0024] This invention achieves the effect of conveying materials by setting up a mounting block and a fixing rod, etc. The rotation of the gear drives the movement of two sets of racks, the movement of the two sets of racks drives the movement of the mounting parts and mounting blocks, the movement of the mounting blocks drives the movement of the clamping parts and mounting rods, and the mounting rods slide in the fixing rods, thereby clamping the materials and saving the cost of manual handling.

[0025] This invention achieves the effect of conveying multiple materials through the cooperation of structures such as connecting frames and clamping components. The movement of two sets of racks drives the installation components and installation blocks to move, and the movement of the installation blocks drives the clamping components and installation rods to move. The installation rods slide in the fixed rods, thereby clamping multiple materials and improving the material conveying efficiency. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1 to 8 As shown, the present invention provides an intelligent material handling device, including a support frame 1 and a conveying unit 2. A drive module 3 is fixedly installed at the lower end of the support frame 1, a clamping module 4 is provided at the upper end of the drive module 3, a fixed seat 5 is fixedly installed at the top of the support frame 1, a movable component 6 is provided at the lower end of the fixed seat 5, and a rectangular block 7 is fixedly installed on one side of the support frame 1.

[0037] The drive module 3 includes a drive motor 301. A connecting shaft 302 is fixedly installed at the output end of the drive motor 301. A first transmission belt 303 and a second transmission belt 305 are provided at the upper end of the connecting shaft 302. A first connecting member 304 is provided at the end of the first transmission belt 303 away from the connecting shaft 302. The second transmission belt 305 is provided at the lower end of the first connecting member 304.

[0038] The clamping module 4 includes a support base 401, a connecting frame 402 is fixedly installed at the bottom of the support base 401, a rack 403 is movably connected to one side of the connecting frame 402, a fixing rod 406 is fixedly installed at one end of the connecting frame 402, and an mounting part 404 is fixedly installed at the bottom of the rack 403.

[0039] The movable component 6 includes a fixed block 601, a movable plate 602 is movably connected to one side of the fixed block 601, two sets of second connecting parts 603 are provided on the top of the fixed base 5, a rectangular plate 605 is provided at the lower end of the second connecting parts 603, and movable parts 606 are provided on both sides of the upper end of the rectangular plate 605.

[0040] The above scheme is adopted: through the cooperation of clamping module 4 and movable component 6, gear 306 rotates to drive two sets of racks 403 to move, the movement of the two sets of racks 403 drives the installation part 404 and installation block 405 to move, the movement of installation block 405 drives the clamping part 407 and installation rod 408 to move, and the installation rod 408 slides in the fixed rod 406, thereby clamping the material. After the material falls, the conveying unit 2 continues to convey the material. At the same time, the second transmission belt 305 drives the second connecting part 603 to rotate, the second connecting part 603 drives the third transmission belt 604 to rotate, the second connecting part 603 drives the rectangular plate 605 to rotate, the rectangular plate 605 drives the two sets of movable parts 606 to rotate, the two sets of movable parts 606 drive the two sets of mounting columns 607 and movable plates 602 to move, and the two sets of movable plates 602 move, thereby organizing the material that falls onto the surface of the conveying unit 2.

[0041] like Figure 2 , Figure 6 and Figure 8 As shown, a mounting block 405 is fixedly mounted on one side of the mounting component 404. A mounting rod 408 is provided at the upper end of the mounting block 405. A clamping component 407 is movably connected to one side of the fixed rod 406. The end of the mounting rod 408 away from the mounting block 405 is movably connected to the clamping component 407. A mounting column 607 is provided at the top of the movable plate 602. The movable component 606 is movably connected to the mounting column 607. A third transmission belt 604 is provided between the two sets of second connecting components 603. A limit groove is provided at the top of the fixed seat 5 and is movably connected to the mounting column 607.

[0042] The above scheme is adopted: through the cooperation of mounting component 404 and mounting block 405, the movement of mounting component 404 drives the movement of mounting block 405, and the movement of mounting block 405 drives the movement of clamping component 407 and mounting rod 408. The clamping component 407 and mounting rod 408 clamp the material. The clamping component 407 is movably connected to one side of the fixed rod 406, so that the clamping component 407 slides in the fixed rod 406, thereby adjusting the distance between the two sets of clamping components 407, and thus clamping the material and conveying the material to the surface of the conveying unit 2. The mounting rod 408 is movably connected to the clamping component 407, so that the clamping component 407 is more stable when moving to clamp the material. Through the cooperation of movable plate 602 and mounting column 607, the design of the mounting column 607 at the top of movable plate 602 makes the rectangular plate When 605 moves the movable part 606 and the mounting column 607, the mounting column 607 moves the movable plate 602, which in turn shapes the material. The cooperation of the second connecting part 603 and the third transmission belt 604 allows the second connecting part 603 to rotate, which in turn rotates the rectangular plate 605. This enables the simultaneous shaping of two sets of material, improving material conveying efficiency. Through the cooperation of the fixed seat 5 and the mounting column 607, and the opening of the limiting groove at the top of the fixed seat 5, the limiting groove limits the movement of the movable plate 602 and the mounting column 607 when the rectangular plate 605 and the movable part 606 move, making the movement of the movable plate 602 and the mounting column 607 more stable.

[0043] like Figure 5 and Figure 6 As shown, gear 306 meshes with rack 403, rectangular block 7 is movably connected to connecting shaft 302, one end of second transmission belt 305 away from connecting shaft 302 is connected to second connecting member 603, the inner wall of clamping member 407 is provided with rubber strip, mounting block 405 is movably connected to fixing rod 406, and mounting block 405 is in the shape of "T".

[0044] The above scheme is adopted as follows: Through the cooperation of gear 306 and rack 403, the first connecting member 304 rotates, driving gear 306 to rotate. The rotation of gear 306 drives two sets of racks 403 to move. The movement of the two sets of racks 403 drives the mounting member 404 and mounting block 405 to move. The movement of mounting block 405 drives the clamping member 407 to move. Rectangular block 7 is movably connected to connecting shaft 302, thereby limiting the connection shaft 302 and making the connection shaft 302 more stable during operation. The second transmission belt 305 is connected to the second connecting member 603. The second transmission belt 305 drives the second connecting member 603 to rotate. The second connecting member 603 drives the third transmission belt 604 to rotate. The second connecting member 603 drives the rectangular plate 605 to rotate. The rectangular plate 605 drives the two sets of movable members 604 to rotate. Rotating at 06, the two sets of movable parts 606 drive the two sets of mounting columns 607 and movable plates 602 to move. The movement of the two sets of movable plates 602 thus organizes the material that has fallen onto the surface of the conveying unit 2. Through the design of the clamping parts 407 and the mounting blocks 405, and the design of the rubber strip on the inner wall of the clamping parts 407, the two sets of clamping parts 407 increase the friction with the material when clamping it, thus making the clamping of the material more stable. The mounting blocks 405 are movably connected to the fixed rods 406, allowing the mounting blocks 405 to move in the through holes of the fixed rods 406, thus enabling the clamping of materials of different sizes. The "T"-shaped design of the mounting blocks 405 makes it better to clamp the material with the clamping parts 407, making the clamping parts 407 clamp the material more stably.

[0045] like Figure 3 , Figure 4 , Figures 6 to 8 As shown, the fixing block 601 is fixedly connected to the fixing seat 5, the first connecting piece 304 is movably connected to the support seat 401, a protrusion is provided on one side of the rack 403, a groove is provided on one side of the connecting frame 402, limit grooves are provided on both sides of the connecting frame 402, and it is movably connected to the mounting piece 404. A sliding groove is provided at the upper end of the fixing block 601, and the inner wall of the sliding groove is smooth. The upper end of the movable plate 602 is L-shaped.

[0046] The above solution is adopted: Through the cooperation of the fixed block 601 and the fixed seat 5, the fixed block 601 and the fixed seat 5 are fixedly connected, making the movable plate 602 more stable when moving outside the fixed block 601. The first connecting piece 304 is movably connected to the support seat 401, causing the first transmission belt 303 to rotate, driving the first connecting piece 304 to rotate. The first connecting piece 304 drives the gear 306 to rotate, the gear 306 drives the rack 403 to move, and the rack 403 drives the mounting piece 404, the mounting block 405, and the fixed rod 406, thereby enabling the clamping piece 407 to clamp the material and transport it to the top of the conveying unit 2. Through the cooperation of the connecting frame 402 and the rack 403, and the design of the protrusion of the rack 403 and the groove of the connecting frame 402, the cooperation of the protrusion and groove of the rack 403 during movement ensures the stability of the rack. The rack 403 is positioned to ensure stability during movement. Limiting grooves on both sides of the connecting frame 402 limit the movement of the mounting component 404, further enhancing stability. The design of the fixed block 601 and the movable plate 602, including the upper sliding groove of the fixed block 601 and the "L"-shaped design of the movable plate 602, ensures stability during movement. The smooth inner wall of the sliding groove reduces friction between the movable plate 602 and the fixed block 601, making movement easier and protecting both the fixed block 601 and the movable plate 602, thus reducing machine wear.

[0047] This application also proposes a method for using an intelligent material handling device, the steps of which are as follows:

[0048] S1. The operator starts the drive motor 301, which drives the connecting shaft 302, the first transmission belt 303 and the second transmission belt 305 to rotate. The first transmission belt 303 drives the first connecting piece 304 to rotate. The rotation of the first connecting piece 304 drives the gear 306 to rotate. The rotation of the gear 306 drives the two sets of racks 403 to move. The movement of the two sets of racks 403 drives the mounting piece 404 and the mounting block 405 to move. The movement of the mounting block 405 drives the clamping piece 407 and the mounting rod 408 to move. The mounting rod 408 slides in the fixed rod 406, thereby clamping the material.

[0049] S2. After clamping, the connecting shaft 302 drives the clamping module 4 to rotate. The clamping module 4 rotates 180 degrees to the upper end of the conveying unit 2. Then the drive motor 301 drives the connecting shaft 302 to rotate in the opposite direction. When rotating, the gear 306 drives the rack 403 to move. The movement of the rack 403 causes the material to fall from between the two sets of clamping parts 407 onto the surface of the conveying unit 2.

[0050] S3. After the material falls, the conveying unit 2 continues to convey the material. At the same time, the second transmission belt 305 drives the second connecting member 603 to rotate, the second connecting member 603 drives the third transmission belt 604 to rotate, the second connecting member 603 drives the rectangular plate 605 to rotate, the rectangular plate 605 drives the two sets of movable members 606 to rotate, the two sets of movable members 606 drive the two sets of mounting columns 607 and movable plates 602 to move, and the two sets of movable plates 602 move, thereby organizing the material that has fallen onto the surface of the conveying unit 2.

[0051] S4. After the materials are sorted, the conveying unit 2 continuously transports the materials, allowing subsequent scanning instruments to scan them. This facilitates the inventory management by warehouse personnel, thereby reducing manual workload and labor costs and improving the material conveying efficiency.
