Technical Field

[0001] This utility model belongs to the field of AGV (Automated Guided Vehicle) technology, specifically relating to an AGV with a conveyor structure. Background Technology

[0002] AGVs, or Automated Guided Vehicles, are intelligent material handling equipment that operate automatically along preset or autonomously planned paths without human drivers to perform tasks such as material handling and cargo transfer. Through the coordinated operation of sensors, navigation systems, and control systems, they achieve "unmanned" operation and have become one of the core pieces of equipment in industrial automation and intelligent logistics. They are widely used in manufacturing, logistics warehousing, and port terminals, effectively improving handling efficiency and reducing labor costs. In the prior art, Chinese utility model patent with patent publication number CN222433321U discloses an AGV trolley that is easy to transport. The AGV trolley includes a vehicle body with symmetrically installed moving wheels on both sides of the vehicle body. A transport box is installed on the upper end of the vehicle body. The lower front side and the right side of the transport box are provided with a connecting opening 1 and opening 2. A placement plate is horizontally installed on the transport box inside the opening 1. Several conveyor belt mechanisms 1 are horizontally installed inside the transport box at the upper end of the opening 1. The placement plate and the conveyor belt mechanisms 1 have the same length and a lifting assembly is installed on the right end. A lifting plate assembly is installed on the lifting assembly. However, in the aforementioned existing AGV technology, the installation positions of conveyor belt mechanism one and conveyor belt mechanism two are fixed. In actual application, when loading and unloading operations are required for goods of different heights, the conveyor belt mechanism one and conveyor belt mechanism two cannot be adaptively adjusted according to the height of the goods. This results in a significant limitation on the loading and unloading height of the AGV, making it difficult to meet diverse loading and unloading needs. This greatly limits its performance in loading and unloading goods and reduces the applicability and operational efficiency of the equipment in complex scenarios. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0014] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 This is the first embodiment of the present invention, which provides an AGV (Automated Guided Vehicle) with a conveying structure, including... Vehicle body 1 serves as the basic frame, providing stable support for the overall equipment. A transport box 2 is installed on the top of vehicle body 1. Installing the transport box 2 on the top of vehicle body 1 can maximize the use of the load-bearing space of vehicle body 1, while avoiding direct contact between the transport box 2 and the ground, reducing the interference of ground debris on the transfer of goods, and ensuring the cleanliness and safety of goods during the transfer process. The conveying structure includes a first conveyor belt mechanism and a second conveyor belt mechanism. The first conveyor belt mechanism includes a first conveyor support 3 fixedly installed at the bottom of the transport box 2, and a first conveyor belt 31 rotatably disposed inside the first conveyor support 3. The first conveyor support 3 provides a stable installation foundation for the first conveyor belt 31, preventing the goods from shifting due to the support swaying during operation. The goods are transported horizontally by rotation. Compared with traditional manual handling, this can improve the efficiency of goods transfer and enable continuous operation, adapting to the high-frequency material transfer needs in industrial scenarios. The second conveyor belt mechanism includes a second conveyor support 4 slidably disposed inside the transport box 2, and a second conveyor belt 41 rotatably disposed inside the second conveyor support 4. The second conveyor support 4 slidably disposed inside the transport box 2 provides a structural basis for the height adjustment of the second conveyor belt mechanism. It can be moved up and down with the help of the adjustment device to meet the loading and unloading needs of goods of different heights. The adjustment device includes a fixed plate 5 installed on the top of the transport box 2, providing a stable mounting carrier for the hydraulic cylinder 51 and preventing displacement of the hydraulic cylinder 51 during operation. The hydraulic cylinder 51 is installed on the top of the fixed plate 5, and its output end passes through the fixed plate 5 and is connected to a horizontal plate 6. Fastening plates 61 are symmetrically arranged at the bottom of the horizontal plate 6 and are fixedly connected to the second conveyor support 4. The hydraulic cylinder 51, as a power source, has the advantages of large output force and stable lifting speed compared with traditional screw drive, and can drive the horizontal plate 6 to lift and lower smoothly. The fastening plates 61 are symmetrically arranged at the bottom of the horizontal plate 6, which can evenly transmit the power of the hydraulic cylinder 51 to the second conveyor support 4 through symmetrical force, preventing the second conveyor support 4 from tilting due to uneven force, and ensuring the stability of the conveyor belt mechanism 2 during lifting and lowering. The fastening plates 61 are fixedly connected to the second conveyor support 4, further strengthening the connection between the two, preventing the conveyor belt mechanism 2 from detaching from the adjustment device when lifting or conveying goods, and improving the safety of equipment operation.

[0015] In this embodiment, preferably, it also includes a support plate 21 symmetrically installed on the top of the transport box 2, and a support column 210 connected to the fixed plate 5 on the support plate 21. The support plate 21 is symmetrically installed on the top of the transport box 2, which can disperse the pressure of the fixed plate 5 on the top of the transport box 2 and prevent the top of the transport box 2 from deforming due to excessive local stress. The support column 210 connects the support plate 21 and the fixed plate 5, which can further improve the installation stability of the fixed plate 5, reduce the impact of the vibration generated by the hydraulic cylinder 51 during operation on the fixed plate 5, and indirectly ensure the overall operating accuracy of the adjustment device.

[0016] In this embodiment, preferably, a baffle 22 is also installed on the side surface of the transport box 2.

[0017] In this embodiment, preferably, it also includes multiple strip-shaped openings on the rear surface of the transport box 2, which can realize air circulation between the inside and outside of the transport box 2, and prevent the temperature inside the transport box 2 from rising due to prolonged sealing. It is especially suitable for the transfer of temperature-sensitive goods. The infrared sensor 8 installed on the transport box 2 can detect the position, quantity and whether there is any obstruction of the goods inside the transport box 2 in real time. When an abnormality is detected, it can promptly feed back to the control system to trigger a stop or adjustment command, thereby improving the safety and accuracy of goods transfer.

[0018] In this embodiment, preferably, it also includes multiple movable wheels 11 set on the vehicle body 1 to provide the AGV with flexible mobility. The control panel 7 installed on the side surface of the vehicle body 1 allows the operator to intuitively view the equipment operating parameters. At the same time, the equipment operating status can be manually adjusted through the control panel 7. When the automatic system fails, manual operation can ensure the basic operation of the equipment and improve the applicability and operability of the equipment.

[0019] In this embodiment, preferably, the top and front openings of the transport box 2 facilitate the installation and maintenance of the adjustment device and can also be adapted to the transfer of some taller goods; the front opening provides a passage for the entry and exit of goods, avoiding the goods from getting stuck due to the limited opening during loading and unloading, thus improving loading and unloading efficiency; the corners of the vehicle body 1 are rounded, which can reduce the collision damage between the equipment and personnel and other equipment during the operation, reduce the risk of safety accidents, and is especially suitable for densely populated factories, warehouses and other scenarios. Example 2

[0020] Please see Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that: The second conveying support 4 and the baffle 22 are provided with sliding components. The sliding components include a sliding plate 42 disposed on the side surface of the second conveying support 4 and a sliding groove 220 opened on the side surface of the baffle 22 for the sliding plate 42 to slide. The cooperation structure between the sliding plate 42 and the sliding groove 220 is simple and practical. When the sliding plate 42 slides in the sliding groove 220, it can accurately limit the lifting trajectory of the second conveying support 4 and prevent the second conveying support 4 from deviating to the left or right.

[0021] The working principle and usage process of this utility model: The goods to be transported are transferred to the first conveyor belt 31 and the second conveyor belt 41 with manual assistance; at this time, the infrared sensor 8 detects the position of the goods on the first conveyor belt 31 and the second conveyor belt 41 in real time. If the goods are deviated or piled up, the sensor will feed back the abnormal signal to the control system, and the control panel 7 will display an early warning prompt. The operator can adjust the running speed of the first conveyor belt 31 and the second conveyor belt 41 through the control panel 7, or manually correct the position of the goods to ensure that the goods are placed stably. The AGV travels along a preset path via a navigation system, and multiple wheels 11 at the bottom of the vehicle body 1 provide flexible mobility. When the AGV arrives at the unloading destination, it stops moving. The operator controls the adjustment device again through the control panel 7 according to the receiving height of the unloading point: the hydraulic cylinder 51 drives the horizontal plate 6, the fastening plate 61 and the second conveyor bracket 4 to move, and adjusts the second conveyor belt 41 to a position that matches the unloading height. The slide plate 42 slides in the slide groove 220 to ensure that the height of the second conveyor belt 41 is accurately positioned. Start the first conveyor belt 31 and the second conveyor belt 41, and the first conveyor belt 31 and the second conveyor belt 41 will transport the goods to the unloading area.

[0022] Although embodiments of the present invention have been shown and described in detail above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
