[0045] This utility model proposes an AGV transport vehicle, which includes a base, a turntable assembly, and a drive assembly. The base includes a first connecting plate and a second connecting plate connected to the first connecting plate. The turntable assembly is vertically and vertically mounted on the top of the base and is used to place goods. The drive assembly is located at the bottom of the first connecting plate and is used to drive the base to move.

[0046] In actual production workshops, the floor cannot be completely flat, and there are uneven areas due to settlement. Furthermore, in order to reduce manual intervention and achieve fully automated loading and unloading, the turntable assembly 30 does not have a limit structure to restrict the batteries or other goods.

[0047] Therefore, in one embodiment, please refer to Figure 1 and Figure 2 In this embodiment, two connecting plates are used to form the base 10. This split connection allows the connection between the first connecting plate 11 and the second connecting plate 12 to absorb level differences caused by ground subsidence during the movement of the base 10 driven by the drive assembly 40. This ensures that the battery or goods remain relatively stationary relative to the base 10 during transport, reducing the risk of shaking and collisions caused by the lack of restraints. This significantly improves the AGV's maneuverability, enhances its adaptability to different road surfaces, and greatly increases its ability to handle uneven loads.

[0048] Specifically, the first connecting plate 11 has a slot 21 on the side facing the second connecting plate 12, and the second connecting plate 12 has a protruding locking strip 22 on the edge facing the first connecting plate 11. The locking strip 22 is used to insert into the slot 21. Through the snap-fit ​​engagement, the first connecting plate 11 and the second connecting plate 12 can be more easily assembled and disassembled, improving convenience.

[0049] The drive assembly 40 may be a tire, fixed to the bottom of the base 10, to move the base 10 and the battery or goods placed on the base 10.

[0050] In this embodiment, during material handling, the drive assembly 40 moves the base 10 to the discharge port 71. The discharge port 71 can be conveyed using a conveying method such as a roller conveyor or a conveyor belt. The turntable assembly 30 can move up and down. When it reaches the discharge port 71, the turntable assembly 30 moves up and down so that the height of the turntable assembly 30 is flush with the discharge port 71.

[0051] Similarly, during material feeding, the drive component 40 moves the base 10 to the feeding port 81, and the turntable component 30 is also adjusted by lifting and moving until the table surface is flush with the feeding port 81. It should be noted that the table surface of the turntable component 30 can be composed of a conveyor belt, and the belt module 33 conveys the batteries or goods on the table surface to the feeding port 81.

[0052] Specifically, the turntable assembly 30 includes a support platform 31, a lifting drive component 3241, and a belt module 33. The bottom of the support platform 31 is provided with a lifting screw. The top of the first connecting plate 11 is provided with a limiting groove, and the lifting drive component 3241 is disposed in the limiting groove. One end of the belt module 33 is connected to the lifting drive component 3241, and the other end is connected to the lifting screw.

[0053] A conveyor belt can be installed on top of the support platform 31. The belt module 33 consists of two fixed pulleys and an annular belt. The annular belt is fitted onto the two fixed pulleys, which pull the annular belt taut to both sides. One of the fixed pulleys is connected to the lifting drive component 3241. The lifting drive component 3241 can be a motor, and its drive shaft is connected to one of the fixed pulleys. The other fixed pulley can be connected to a gear via a pin, and then to a lifting screw via the gear. The two fixed pulleys rotate synchronously via the annular belt. The fixed pulleys then rotate synchronously with the gear, thereby engaging the lifting screw to raise and lower it, thus driving the support platform 31 to rise and fall.

[0054] Furthermore, in this embodiment, the turntable assembly 30 also includes a rotary drive 3441. The rotary drive 3441 can be connected to the support platform 31 via a drive shaft to drive the support platform 31 to rotate. By rotating the support platform 31, the feeding direction of batteries or other goods can be adjusted, so that the batteries can be stably fed into the feeding port 81.

[0055] The support platform 31 is cylindrical, and the rotation axis of the drive shaft of the rotary drive component 3441 overlaps with the central axis of the support platform 31. The cylindrical structure prevents the edges of the support platform 31 from colliding with other external structures during rotation. Furthermore, the use of a concentric shaft ensures that the support platform 31 rotates around its central axis, preventing positional shifts during rotation.

[0056] The rotary drive component 3441 can be achieved by connecting a motor with a platform, and the support platform 31 is set on the platform.

[0057] In this utility model, the base 10 is provided with a first connecting plate 11 and a second connecting plate 12 separately, and the drive assembly 40 is set at the bottom of the first connecting plate 11 to form a suspension function, so as to improve the shock absorption capability of the AGV transport vehicle during the driving process, avoid battery shaking, and improve the production quality of the vehicle.

[0058] In another embodiment, the drive assembly 40 includes a drive wheel 42, two drive members 41 and two driven wheels 43. The two drive members 41 are respectively disposed on opposite sides of the bottom of the first connecting plate 11. Each drive member 41 is correspondingly provided with one drive wheel 42. The two driven wheels 43 are disposed between the two drive members 41, and the two driven wheels 43 are spaced apart along a direction perpendicular to the rotation axis of the drive wheel 42.

[0059] Two drive wheels 42 are respectively located on the left and right sides of the first connecting plate 11. Each drive wheel 42 is independent and is driven by a corresponding drive component 41. The drive component 41 can be a motor or the like. Thus, by controlling the forward and reverse rotation of the drive wheels 42 on the left and right sides respectively, operations such as turning the base 10 in place can be achieved.

[0060] In addition, the drive assembly 40 also includes a reducer, drive wheel, driver, etc. The drive assembly 40 can be controlled by an independent servo drive system, which can realize precise closed-loop control of the speed and position of the drive system to achieve flexible path control, such as linear forward, linear backward, in-place rotation, and follow-up rotation. The drive system has a safety protection design, with protection against over-temperature, over-current, short circuit, and overload, effectively preventing loss of control.

[0061] Two driven wheels 43 are spaced apart between the two driving wheels 42. The cooperation between the driving wheels 42 and the driven wheels 43 further improves the stability of the base 10 during movement. When the front of the base 10 encounters a steep position, the rear of the base 10 can still remain stable.

[0062] Furthermore, the drive assembly 40 also includes a first connecting rod 46, a second connecting rod 47, a first pin 44, and a second pin 45, with the first pin 44 and the second pin 45 respectively disposed on both sides of the turntable assembly 30; one end of the first connecting rod 46 is connected to the first connecting plate 11, and the other end is connected to the first pin 44; one end of the second connecting rod 47 is connected to the second connecting plate 12, and the other end is connected to the second pin 45.

[0063] The lifting, lowering, and rotation of the support platform 31 are crucial to overall safety and efficiency. Therefore, this embodiment employs a high-performance multi-link structure. The first pin 44 and the second pin 45 are fixed to the bottom of the support platform 31 via a bracket, and connected to the first connecting plate 11 and the second connecting plate 12 via the first connecting rod 46 and the second connecting rod 47, respectively. This design changes the previous screw-driven lifting structure, providing a rear suspension effect, thereby significantly improving operational stability, increasing the lifting efficiency of the support platform 31, reducing noise, and making handling more reliable.

[0064] Furthermore, the AGV transport vehicle also includes a shock-absorbing bracket 50, a navigation module 61, and a barcode scanning module 62. The shock-absorbing bracket 50 is mounted on the base 10; the navigation module 61 and the barcode scanning module 62 are both mounted on the shock-absorbing bracket 50.

[0065] Specifically, the AGV transport vehicle is also equipped with a controller, which can be a PLC controller.

[0066] On-site operators insert two pre-packaged batteries or other goods into the discharge port 71, which is then moved to the discharge port 71 by the drive assembly 40. Once in position, the communication PLC controller uses a cylinder to open the side limit switch of the trolley, and the batteries are automatically moved into the turntable assembly 30. An empty tray can be placed on the turntable assembly 30. After the batteries are placed on the empty tray, the control cylinder closes, and the drive assembly 40 drives the batteries away from the discharge port 71.

[0067] The navigation module 61 can use SLAM navigation recognition to identify the positions of surrounding obstacles and feed back the coordinates to the controller. After stopping at the charging position, the power supply 63 controls the charging process. Once charging is complete, the material enters the feeding port 81. A QR code for positioning is set on the workshop floor. The scanning module 62 scans towards the bottom of the base 10, using the QR code on the floor to accurately locate the stopping position for feeding operations. At the same time, the empty pallet is retrieved, and this process is repeated.

[0068] Furthermore, the AGV transport vehicle also includes a power supply 63 and a lidar 64. The power supply 63 is mounted on the base 10; the lidar 64 is mounted on the base 10 and is electrically connected to the power supply 63.

[0069] The navigation and positioning system uses SLAM navigation technology to calculate and determine the position and direction of the AGV transport vehicle, so as to know its own location and direction, ensuring that the AGV transport vehicle moves along the predetermined path and does not deviate from the target coordinate point.

[0070] The navigation and positioning system uses two LiDAR sensors (64) to scan and acquire information about the surrounding environment. During the AGV's operation, it continuously provides the AGV's coordinates and attitude angles relative to the map, providing real-time correction and maintaining a stable travel path. It also includes a 2D address code reader for precise positioning in high-precision applications, ensuring operational accuracy.

[0071] This utility model also proposes an AGV handling device; please refer to [reference needed]. Figure 3 The AGV handling equipment uses the AGV handling trolley as described above. The AGV handling equipment includes a packaging line 70 and a transport line 80. The packaging line 70 has a discharge port 71; the transport line 80 has a feeding port 81, and a transport channel is formed between the feeding port 81 and the discharge port 71. The AGV handling trolley is movably mounted on the transport line 80 to receive materials at the discharge port 71 and transport the materials to the feeding port 81 for feeding. The AGV handling trolley is used to lift the turntable assembly 30 to dock with the discharge port 71 or the feeding port 81.
