This involves a lot of manual intervention, low efficiency, and difficulty in meeting the timeliness requirements of logistics. Therefore, a loading and unloading device for smart logistics is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a loading and unloading device and its method of use for intelligent logistics, addressing the problems mentioned in the background section. Currently, logistics loading and unloading is a labor-intensive industry, and existing handcarts have simple structures, serving only the function of transporting goods. With the rapid development of the logistics industry, the amount of goods requiring handling is constantly increasing. However, the loading and unloading function of existing handcarts is mainly provided by external loading and unloading equipment or manual labor, resulting in excessive manual intervention, low efficiency, and difficulty in meeting the timeliness requirements of logistics. To achieve the above objective, this invention provides the following technical solution: a loading and unloading device and its method of use for intelligent logistics, comprising a carrier vehicle body; A connecting frame is fixedly connected to one side of the carrier body.

A connecting column is fixedly connected to one side of the support plate, and a laser detector for detecting the height of an object is fixedly installed on one side of the connecting column. The interior of the movable frame is equipped with auxiliary components to assist in the entry of goods. This type of loading and unloading device is used for intelligent logistics. More preferably, a walking unit is fixedly installed on one side of the carrier body, a push-pull handle is fixedly connected to one side of the connecting frame, a motor for driving the threaded rod to rotate is fixedly installed on one side of the carrier body, and a control box is fixedly installed on one side of the connecting frame. This loading and unloading device for smart logistics achieves flexible adjustment of the cargo loading and unloading direction through the multi-directional movement adjustment of the adsorption component and the coordinated cooperation of the auxiliary components. The adsorption component detects the cargo height in real time through a laser detector and adjusts the position and height of the adsorption component in real time to ensure accurate positioning of the cargo during loading and unloading. Based on the detected cargo height, the stacking height of subsequent cargo is adjusted to achieve neat stacking of cargo, realize automated cargo loading and unloading operations, reduce manual intervention, improve loading and unloading efficiency, reduce labor costs, and is suitable for batch cargo processing in logistics warehousing scenarios.

[0005] More preferably, an auxiliary support column is fixedly connected to one side of the carrier body, the auxiliary support column passes through the movable frame, and a motor is fixedly installed on one side of the movable frame.

[0006] More preferably, a transmission wheel is fixedly installed at the output end of the motor, and the same transmission wheel is fixedly connected to the side surface of the rotating shaft. The two sets of transmission wheels are rotatably connected by a belt.

[0007] More preferably, a negative pressure air pump is fixedly installed on one side of the support plate, and the suction end of the negative pressure air pump is fixedly connected to the connecting pipe through a pipeline.

[0008] More preferably, the auxiliary component includes a trapezoidal plate, which is fixedly connected to one side of the movable frame. An installation groove is provided on one side of the trapezoidal plate, and a rotating roller is movably connected to one side of the installation groove. A drive shaft passes through one side of the rotating roller, and a sprocket gear is fixedly connected to the side surface of the drive shaft. In this loading and unloading device for intelligent logistics, when the adsorption component moves the goods to the auxiliary component, the drive chain synchronously drives the rotating roller to rotate. The rotating roller can adjust the conveying angle according to the loading and unloading direction of the goods, assisting the goods to smoothly enter the carrier vehicle or accurately unload to the target position, avoiding the problem of dead angles caused by a fixed loading and unloading direction.

[0009] More preferably, the side surface of the sprocket toothed disc three meshes with the transmission chain, and one end of the transmission shaft passes through one side of the movable frame, with one section located inside the placement groove.

[0010] More preferably, a rolling wheel is fixedly connected to one side of the connecting block, the rolling wheel is rotatably connected to the inner wall of the support slide rail, a slide rail is fixedly connected to one side of the support plate, and a threaded rod is rotatably connected to one side of the connecting column.

[0011] In a further preferred embodiment, the sliding block is slidably connected to the slide rail, and the sliding block is threadedly connected to the threaded rod. A motor is fixedly installed on one side of the support plate, and a transmission wheel is fixedly installed on the output end of the motor. The same transmission wheel is fixedly installed on the side surface of the threaded rod. The two sets of transmission wheels are connected by a belt. In this loading and unloading device for smart logistics, the motor drives the threaded rod to rotate, causing the sliding block to slide left and right along the slide rail. This allows the adsorption component to be precisely aligned with goods at different lateral positions, and the loading and unloading of multiple rows of goods can be completed without the need for an overall moving device.

[0012] A loading and unloading device for smart logistics, the method of using it includes the following steps: Step 1: Using the walking section on one side of the vehicle body, push the device to the vicinity of the goods to be loaded or unloaded, and adjust its position by pushing or pulling the handrail to align the device with the goods, while ensuring that the auxiliary support column can provide stable support for the mobile frame. Step 2: Start motor 3. The output of motor 3 drives threaded rod 1 to rotate. Since threaded rod 1 is threadedly connected to the moving frame and the moving frame is sleeved on the auxiliary support column, the moving frame will move up and down along the auxiliary support column when threaded rod 1 rotates, adjusting to a suitable height for subsequent handling of goods. Step 3: Start motor one. The output of motor one drives transmission wheel one to rotate, which in turn drives another transmission wheel one to rotate via a belt, thereby driving the rotating shaft one to rotate. The sprocket toothed disc one on the rotating shaft one drives sprocket toothed disc two to rotate via a transmission chain. The connecting block fixedly connected to the transmission chain moves accordingly, thereby driving the support plate to move along the support slide rail. At the same time, the transmission chain also drives sprocket toothed disc three in the auxiliary component to rotate, causing the rotating roller to rotate. Start motor two. The output of motor two drives transmission wheel two to rotate, which in turn drives another transmission wheel two to rotate via a belt, thereby driving threaded rod two to rotate. The sliding block threadedly connected to threaded rod two and sliding on the slide rail moves, thereby adjusting the position of the adsorption component so that the negative pressure suction pad is aligned with the goods. Step 4: Start the negative pressure air pump to create negative pressure in the suction pad through the connecting pipe, which will adsorb the goods. If the goods are materials that can be electromagnetically attracted, such as metal, activate the electromagnetic block to enhance the adsorption effect. Step 5: After adsorbing the goods, reverse motor one, causing the adsorption component to move towards the connecting frame. The goods move to the trapezoidal plate, and the rotation of the rotating roller assists the goods in entering the carrier body. Once the goods are placed on the carrier body, the adsorption component cancels the adsorption. The laser detector detects the height of the goods in real time and assists in adjusting the position and height of the device. The adsorption component moves forward repeatedly. When the adsorption component moves to the adsorption position, the position of the adsorption component is adjusted by rotating the threaded rod one to adsorb the next item of goods. The height of the previous item is detected by the laser detector, and the height of the adsorption component is adjusted so that the next item of goods accumulates on top of the previous item. Step Six: In conjunction with the traveling unit's moving device, the goods are transported to the designated location. During the loading and unloading process, the laser detector monitors the height of the goods in real time, assisting in adjusting the position and height of the device. The adsorption component pushes the goods from the higher position onto the auxiliary component in sequence. The height of the moving frame is adjusted by rotating the threaded rod, and the goods are delivered to the designated location. The rotating roller in the auxiliary component rotates under the drive of the transmission chain, assisting in the movement of the goods. In conjunction with the traveling unit's moving device, the goods are transported to the designated location. A pallet is placed on the carrier vehicle. The device neatly stacks the goods on the pallet through the above steps, and finally, the goods are transferred in one go by forklift.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, the direction of cargo loading and unloading is flexibly adjusted through the multi-directional movement adjustment of the adsorption component and the coordinated cooperation of the auxiliary components. The adsorption component detects the height of the cargo in real time through a laser detector and adjusts the position and height of the adsorption component in real time to ensure the accurate positioning of the cargo during loading and unloading. Based on the detected cargo height, the stacking height of subsequent cargo is adjusted to achieve neat stacking of cargo, realize the automated operation of cargo loading and unloading, reduce manual intervention, improve loading and unloading efficiency, reduce labor costs, and is suitable for batch cargo processing in logistics and warehousing scenarios.

[0014] In this invention, the adsorption component adopts a dual adsorption structure that combines negative pressure adsorption and electromagnetic adsorption, which effectively improves the adsorption stability of goods of different materials. When the adsorption component moves the goods to the auxiliary component, the transmission chain synchronously drives the rotating roller to rotate. The rotating roller can adjust the conveying angle according to the loading and unloading direction of the goods, which helps the goods to smoothly enter the carrier or accurately unload to the target position, avoiding the problem of dead angles caused by fixed loading and unloading direction.

The output end of the motor 31 drives the threaded rod 14 to rotate. Since the threaded rod 14 is threadedly connected to the movable frame 7 and the movable frame 7 is sleeved on the auxiliary support column 12, the movable frame 7 will move up and down along the auxiliary support column 12 when the threaded rod 14 rotates. A control box 11 is fixedly installed on one side of the connecting frame 3. The control box 11 is used to control the start of various components of the device.

[0021] The method of use and advantages of the present invention: The loading and unloading device for smart logistics and its method of use, in use, the working process is as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, step one: using the walking part 2 on one side of the carrier body 1, push the device to the vicinity of the goods to be loaded or unloaded, and adjust the position by pushing and pulling the handrail 5 to align the device with the goods, while ensuring that the auxiliary support column 12 can provide stable support for the mobile frame 7. Step 2: Start motor 31. The output end of motor 31 drives threaded rod 14 to rotate. Since threaded rod 14 is threadedly connected to movable frame 7 and movable frame 7 is sleeved on auxiliary support column 12, when threaded rod 14 rotates, movable frame 7 will move up and down along auxiliary support column 12 to adjust to a suitable height for subsequent operation of goods. Step 3: Start motor 8. The output of motor 8 drives transmission wheel 9 to rotate. Through the belt, another transmission wheel 9 rotates, which in turn drives the rotating shaft 17 to rotate. The sprocket toothed disc 18 on the rotating shaft 17 drives the sprocket toothed disc 20 to rotate through the transmission chain 21. The connecting block 25, which is fixedly connected to the transmission chain 21, moves accordingly, thereby driving the support plate 22 to move along the support slide rail 10. At the same time, the transmission chain 21 also drives the sprocket toothed disc 605 in the auxiliary component 6 to rotate, causing the rotating roller 604 to rotate. Start motor 29. The output of motor 29 drives transmission wheel 30 to rotate. Through the belt, another transmission wheel 30 rotates, which in turn drives the threaded rod 28 to rotate. The sliding block 401, which is threadedly connected to the threaded rod 28 and slides on the slide rail 23, moves, thereby adjusting the position of the adsorption component 4 so that the negative pressure suction pad 403 is aligned with the goods. Step 4: Start the negative pressure air pump 15, which generates negative pressure in the negative pressure suction pad 403 through the connecting pipe 405 to adsorb the goods. If the goods are materials that can be electromagnetically adsorbed, such as metal, start the electromagnetic block 404 to enhance the adsorption effect. Step 5: After adsorbing the goods, reverse motor 8 causes adsorption component 4 to move towards connecting frame 3. The goods move onto trapezoidal plate 601. The rotation of rotating roller 604 assists the goods in entering the carrier body 1. Once the goods are placed on the carrier body 1, adsorption component 4 cancels adsorption. Laser detector 27 detects the height of the goods in real time and assists in adjusting the position and height of the device. Adsorption component 4 moves forward repeatedly. When adsorption component 4 moves to the adsorption position, the position of adsorption component 4 is adjusted by rotating threaded rod 14 to adsorb the next item of goods. The height of the previous item is detected by laser detector 27, and the height of adsorption component 4 is adjusted so that the next item of goods accumulates on top of the previous item. Step Six: In conjunction with the moving device of the walking unit 2, the goods are transported to the designated location. During the loading and unloading process, the laser detector 27 detects the height of the goods in real time and assists in adjusting the position and height of the device. The adsorption component pushes the goods from the high position to the auxiliary component 6 in sequence. The height of the moving frame 7 is adjusted by rotating the threaded rod 14 to deliver the goods to the designated location. The rotating roller 604 in the auxiliary component 6 rotates under the drive of the transmission chain 21 to assist in the movement of the goods. In conjunction with the moving device of the walking unit 2, the goods are transported to the designated location. The pallet is placed on the carrier vehicle 1. The device neatly stacks the goods on the pallet through the above steps and finally transfers them in one go by forklift.

The two sets of transmission wheels (30) are connected by a belt.

10. A method of using a smart logistics loading and unloading device according to any one of claims 1-9, characterized in that: Includes the following steps: Step 1: Using the walking part (2) on one side of the carrying vehicle body (1), push the device to the vicinity of the goods to be loaded or unloaded, and adjust the position by pushing and pulling the handrail (5) to align the device with the goods, while ensuring that the auxiliary support column (12) can provide stable support for the moving frame (7). Step 2: Start motor 3 (31). The output end of motor 3 (31) drives threaded rod 1 (14) to rotate. Since threaded rod 1 (14) is threadedly connected to the moving frame (7) and the moving frame (7) is sleeved on the auxiliary support column (12), when threaded rod 1 (14) rotates, the moving frame (7) will move up and down along the auxiliary support column (12) to adjust to a suitable height so that the goods can be operated later. Step 3: Start motor one (8). The output end of motor one (8) drives transmission wheel one (9) to rotate, which in turn drives another transmission wheel one (9) to rotate via a belt, thereby driving the rotating shaft one (17) to rotate. The sprocket tooth disk one (18) on the rotating shaft one (17) drives the sprocket tooth disk two (20) to rotate via the transmission chain (21). The connecting block (25) fixedly connected to the transmission chain (21) moves accordingly, thereby driving the support plate (22) to move along the support slide rail (10). At the same time, the transmission chain (21) also... This will drive the sprocket toothed disc three (605) in the auxiliary component (6) to rotate, causing the rotating roller (604) to rotate, starting the motor two (29). The output end of the motor two (29) drives the transmission wheel two (30) to rotate, which in turn drives another transmission wheel two (30) to rotate via the belt, thereby driving the threaded rod two (28) to rotate. The sliding block (401), which is threadedly connected to the threaded rod two (28) and slides on the slide rail (23), moves, thereby adjusting the position of the adsorption component (4) so ​​that the negative pressure suction pad (403) is aligned with the goods. Step 4: Start the negative pressure air pump (15) to generate negative pressure in the negative pressure suction pad (403) through the connecting pipe (405) to adsorb the goods. If the goods are metal or other materials that can be electromagnetically adsorbed, start the electromagnetic block (404) to enhance the adsorption effect. Step 5: After adsorbing the goods, reverse motor 1 (8) is reversed so that the adsorption component (4) moves towards the connecting frame (3) and the goods move to the trapezoidal plate (601). The rotation of the rotating roller (604) assists the goods to enter the carrier body (1). When the goods are placed on the carrier body (1), the adsorption component (4) cancels adsorption. The laser detector (27) detects the height of the goods in real time and assists in adjusting the position and height of the device. The adsorption component (4) moves forward repeatedly. When the adsorption component (4) moves to the adsorption position, the position of the adsorption component (4) is adjusted by the rotation of the threaded rod 1 (14) to adsorb the next goods. The height of the previous goods is detected by the laser detector (27), and the height of the adsorption component (4) is adjusted so that the next goods accumulate above the previous goods. Step 6: In conjunction with the moving device of the walking unit (2), the goods are transported to the designated location. During the loading and unloading of the goods, the laser detector (27) detects the height of the goods in real time and assists in adjusting the position and height of the device. The adsorption component pushes the goods from the high position to the auxiliary component (6) in sequence. The height of the moving frame (7) is adjusted by rotating the threaded rod (14) to deliver the goods to the designated location. The rotating roller (604) in the auxiliary component (6) rotates under the drive of the transmission chain (21) to assist in the movement of the goods. In conjunction with the moving device of the walking unit (2), the goods are transported to the designated location. The pallet is placed on the carrier vehicle (1). The device neatly stacks the goods on the pallet through the above steps and finally transfers them in one go by forklift.
