Description

Technical Field

[0001] This utility model relates to the field of transfer vehicle technology, specifically to an AGV transfer vehicle. Background Technology

[0002] AGV (Automated Guided Vehicle) transport vehicles, as important equipment in automated logistics systems, are widely used in factories, warehouses, and other places for automated material handling. In practical applications, the lifting function of the AGV's loading platform is a key link in achieving accurate material transfer.

[0003] However, existing AGV transfer vehicles often struggle to balance lifting speed and accuracy during the lifting of cargo pallets. If only lifting speed is prioritized, the cargo pallet may deviate significantly when it reaches the target position, affecting the accuracy of material handover. If lifting accuracy is emphasized, the lifting speed will be slower, reducing transfer efficiency and failing to meet the needs of modern, efficient logistics. Utility Model Content

[0004] In view of the problems existing in the above-mentioned transfer vehicles, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an AGV transfer vehicle that solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An AGV (Automated Guided Vehicle) transfer vehicle includes a transfer vehicle chassis and a steering wheel. The steering wheel is rotatably mounted on the upper surface of the transfer vehicle chassis. A lifting plate is disposed above the steering wheel, and a carrying plate is disposed above the lifting plate. Fixed tubes are fixedly disposed at the four corners of the upper surface of the lifting plate. Movable rods are movably sleeved inside the fixed tubes. The upper ends of the movable rods are fixedly connected to the carrying plate. A first transmission mechanism is disposed on the upper surface of the steering wheel to drive the lifting plate to move rapidly, and a second transmission mechanism is disposed above the lifting plate to drive the carrying plate to move precisely.

[0007] Preferably, the first transmission mechanism includes a transmission rod and an electric push rod. The electric push rod is fixedly disposed on one side of the upper surface of the steering wheel. Two transmission rods are disposed on both sides of the piston end of the electric push rod. A first connecting rod is rotatably sleeved at the piston rod end of the electric push rod. Both ends of the first connecting rod are rotatably connected to the corresponding transmission rod. A second connecting rod is rotatably connected at the end of the two transmission rods away from the first connecting rod. Both ends of the second connecting rod are rotatably connected to a connecting block. The upper side of the connecting block is fixedly connected to the lifting plate.

[0008] Preferably, the second transmission mechanism includes a bidirectional lead screw and a sliding plate. Side plates are fixedly provided on both sides of the upper surface of the lifting plate. The bidirectional lead screw is rotatably disposed between the two side plates. The two sliding plates are threaded onto the two ends of the bidirectional lead screw. A first groove is provided on both sides of the upper surface of the sliding plate. A fixing plate is fixedly provided on both sides of the lower surface of the carrying plate. A second groove is provided on the lower surface of both ends of the fixing plate. A rotating strip is provided between the first groove and the corresponding second groove. A shaft pin is rotatably sleeved on both ends of the rotating strip. Both ends of the shaft pin are rotatably connected to the inner wall of the corresponding first groove and the corresponding second groove. A motor is fixedly provided on the outer wall of one side plate. The output end of the motor is fixedly connected to one end of the bidirectional lead screw.

[0009] Preferably, the upper surface of the lifting plate has through holes at all four corners, and a sliding rod is slidably disposed inside the through hole, with the upper end of the sliding rod being fixedly connected to the carrying plate.

[0010] Preferably, an anti-detachment block is fixedly provided at the lower end of the slide rod.

[0011] Preferably, a limiting rod is provided parallel to one side of the bidirectional lead screw, and both ends of the limiting rod are fixedly connected to the corresponding side plate. One side of the slide plate is movably sleeved with the limiting rod.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model uses an electric push rod piston rod to extend, causing the transmission rod to rotate towards a vertical position, thereby enabling the lifting plate to rise quickly and thus achieving rapid lifting and lowering of the carrying plate, which can quickly bring the carrying plate closer to the goods.

[0013] 2. This utility model uses a motor to drive a bidirectional lead screw to rotate, causing two sliding plates to move in opposite directions. This drives the rotating bar to rotate towards a vertical position, thereby enabling the loading plate to be raised precisely for accurate material receiving. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model discloses an AGV transfer vehicle.

[0019] This utility model provides, for example Figure 1-3 The AGV transfer vehicle shown includes a transfer vehicle chassis 1 and a steering wheel 2. The steering wheel 2 is rotatably mounted on the upper surface of the transfer vehicle chassis 1. A lifting plate 3 is mounted above the steering wheel 2, and a carrying plate 4 is mounted above the lifting plate 3. Fixed tubes 5 are fixedly mounted at the four corners of the upper surface of the lifting plate 3. Movable rods 6 are movably sleeved inside the fixed tubes 5. The upper ends of the movable rods 6 are fixedly connected to the carrying plate 4. A first transmission mechanism is provided on the upper surface of the steering wheel 2 to drive the lifting plate 3 to move quickly, and a second transmission mechanism is provided above the lifting plate 3 to drive the carrying plate 4 to move precisely.

[0020] like Figure 1-3 As shown, the first transmission mechanism includes a transmission rod 10 and an electric push rod 8. The electric push rod 8 is fixedly mounted on one side of the upper surface of the steering wheel 2. Two transmission rods 10 are mounted on both sides of the piston end of the electric push rod 8. The piston rod end of the electric push rod 8 is rotatably sleeved with a first connecting rod 9. Both ends of the first connecting rod 9 are rotatably connected to the corresponding transmission rod 10. The ends of the two transmission rods 10 away from the first connecting rod 9 are rotatably connected to a second connecting rod 11. Both ends of the second connecting rod 11 are rotatably connected to a connecting block 20. The upper side of the connecting block 20 is fixedly connected to the lifting plate 3.

[0021] like Figure 1-3As shown, the second transmission mechanism includes a bidirectional lead screw 13 and a sliding plate 15. Side plates 12 are fixedly installed on both sides of the upper surface of the lifting plate 3. The bidirectional lead screw 13 is rotatably installed between the two side plates 12. The two sliding plates 15 are threadedly sleeved on both ends of the bidirectional lead screw 13. A first groove is opened on both sides of the upper surface of the sliding plate 15. A fixing plate 19 is fixedly installed on both sides of the lower surface of the carrying plate 4. A second groove is opened on the lower surface of both ends of the fixing plate 19. A rotating bar 16 is provided between the first groove and the corresponding second groove. A shaft pin 17 is rotatably sleeved on both ends of the rotating bar 16. Both ends of the shaft pin 17 are rotatably connected to the inner wall of the corresponding first groove and the corresponding second groove. A motor 14 is fixedly installed on the outer wall of one side plate 12. The output end of the motor 14 is fixedly connected to one end of the bidirectional lead screw 13. A limit rod 18 is arranged parallel to one side of the bidirectional lead screw 13. Both ends of the limit rod 18 are fixedly connected to the corresponding side plate 12. One side of the sliding plate 15 is movably sleeved with the limit rod 18, so that the sliding plate 15 can slide stably.

[0022] like Figure 1-3 As shown, the upper surface of the lifting plate 3 has through holes at all four corners. A sliding rod 7 is slidably installed inside the through hole. The upper end of the sliding rod 7 is fixedly connected to the carrying plate 4, so that the carrying plate 4 can move stably relative to the lifting plate 3. An anti-detachment block is fixedly installed at the lower end of the sliding rod 7 to prevent the lower end of the sliding rod 7 from slipping out of the through hole as much as possible.

[0023] In this invention, during use, the AGV transport vehicle moves to the target material storage location via its built-in navigation system. After the transport vehicle chassis 1 stops, the steering wheel 2 rotates according to a preset program or feedback from on-site sensors, adjusting the direction of the loading plate 4 to face the material. First, the first transmission mechanism is activated; the electric push rod 8 is powered on, and its piston rod extends. The first connecting rod 9 at the end of the piston rod moves forward. Since the two ends of the first connecting rod 9 are rotatably connected to the transmission rod 10, the two transmission rods 10 rotate rapidly in the vertical direction around their connection point with the steering wheel 2, thereby driving the second connecting rod 11 to move upward. The second connecting rod 11 is connected to the lifting plate 3 via connecting blocks 20 at both ends, causing the lifting plate 3 to rise rapidly, significantly shortening the time to approach the material and improving transport efficiency. When the carrying plate 4 rises rapidly to a position close to the bottom of the material, the second transmission mechanism is activated, the motor 14 is powered on and runs, and its output end drives the bidirectional lead screw 13 to rotate. Since the threads at both ends of the bidirectional lead screw 13 rotate in opposite directions, the two slide plates 15 move in opposite directions along the limit rod 18 respectively. The pin 17 in the first groove on the upper surface of the slide plate 15 drives the rotating bar 16 to rotate. The pin 17 at the other end of the rotating bar 16 pushes the second groove of the fixing plate 19 on the lower surface of the carrying plate 4, so that the carrying plate 4 is guided by the slide rod 7 and the movable rod 6 to make precise micro-lifting and adjusting. Through the precise speed control of the motor 14 and the precision transmission of the bidirectional lead screw 13, the carrying plate 4 can accurately fit the bottom of the material, ensuring that the material is placed stably and accurately on the carrying plate 4.

[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
