Description

Technical Field

[0001] This utility model belongs to the field of AGV (Automated Guided Vehicle) technology, specifically an automatic unhooking device for AGVs. Background Technology

[0002] In the fields of modern logistics and industrial production, AGVs (Automated Guided Vehicles) have emerged and developed rapidly. With the popularization of the concept of intelligent manufacturing, enterprises have placed higher demands on the automation, intelligence, and efficiency of production processes. Traditional material handling methods rely heavily on manual labor, which is not only inefficient but also prone to human error, making it difficult to meet the needs of large-scale, fast-paced production. AGVs were developed to address these pain points. They can automatically travel along preset paths to complete tasks such as material handling and goods delivery. Their applications are wide-ranging, covering material transfer between production lines in factory workshops and inbound / outbound operations in warehousing and logistics centers.

[0003] CN201410267603.8 discloses an AGV (Automated Guided Vehicle) tail swing mechanism and an AGV. The AGV includes a vehicle body, a navigation device mounted on the vehicle body, and safety components; it also includes a rotating support, at least two omnidirectional drive wheels, and at least two directional wheels. The rotating support has a flat plate structure with a connecting component at its center. The rotating support is mounted on the bottom rear end of the vehicle body via the connecting component. The directional wheels are respectively mounted on both ends of the rotating support, which supports the left-right swing of the directional wheels. The omnidirectional drive wheels are fixedly mounted on the bottom front end of the vehicle body. The omnidirectional drive wheels drive the vehicle body, and the directional wheels rotate and support the vehicle body while the drive wheels are driving the vehicle body.

[0004] In the above technical solution, a universal drive wheel and a directional wheel structure mounted on a rotating support are used to adapt to uneven ground and uneven force points of the two directional wheels when passing through curves. It also shortens the longitudinal dimension of the vehicle body and reduces the volume of the AGV to save space. However, since there is no fixing device on the vehicle body to fix the box, it is impossible to drag the box to the designated position for placement. Utility Model Content

[0005] The purpose of this utility model is to solve the above problems and provide an automatic unhooking device for AGV carts. This device drives the hook mechanism to hook the handle of the box to fix the box, thereby enabling the AGV cart to move the box to a designated position for placement.

[0006] Furthermore, due to the high height of the vehicle body and the low position of the external frame box, the handle can be better hooked and fixed by setting an inclined mounting plate.

[0025] 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.

[0026] Example 1

[0027] refer to Figures 1-3 An automatic unhooking device for an AGV (Automated Guided Vehicle) includes a vehicle body and a mounting plate, characterized in that the mounting plate is inclinedly disposed on the vehicle body;

[0028] The mounting plate 2 is provided with a swingable hook mechanism 5, and also includes a drive mechanism 4 provided on the mounting plate 2. The drive mechanism 4 is connected to the hook mechanism 5 and is used to drive the swing of the hook mechanism 5 to hook the handle 8 of the external frame box.

[0029] In this design, the mounting plate is tilted on the top of the vehicle body. Since the handle 8 of the external frame box is swingable, the handle 8 is swung so that the angle of the swing is the same as the tilt angle of the mounting plate. Then, the handle 8 is placed on the mounting plate. Next, the drive mechanism 4 is controlled to drive the hook mechanism 5 to swing, thereby hooking and fixing the handle 8 of the frame box. After hooking, the vehicle body 1 can move the frame box. After the frame box is moved to the designated position, the drive mechanism 4 is controlled to swing again to release the hook and loosen the fixing of the handle 8 of the frame box for the movement of the next frame box. In this way, the handle can be hooked and fixed more effectively.

[0030] In this embodiment, the vehicle body 1 is also provided with an angle adjustment mechanism 3 connected to the mounting plate 2, and the angle adjustment mechanism 3 is used to adjust the tilt angle of the mounting plate 2;

[0031] The angle adjustment mechanism 3 includes two fixed plates 31 spaced apart on the vehicle body 1. The fixed plates 31 have arc-shaped through grooves 311 on their sides. The mounting plate 2 has bolt holes 21 on both sides. The mounting plate 2 is connected between the two fixed plates 31 by bolts passing through the arc-shaped through grooves 311 and bolt holes 21.

[0032] Specifically, when adjusting the tilt height of the mounting plate 2, the worker manually adjusts the tilt angle of the mounting plate 2, and then inserts the bolt through the arc-shaped groove 311 of the fixing plate 31 into the bolt hole 21 of the fixing plate 31 to complete the fixing of the mounting plate 2.

[0033] Preferably, the mounting plate 2 is further included with a hinge 6, through which the bottom of the mounting plate 2 and the top of the vehicle body 1 are connected. By using the hinge 6 to connect the bottom of the mounting plate 2 and the top of the vehicle body 1, the vibration of the mounting plate 2 during the movement of the vehicle body 1 can be reduced.

[0034] Preferably, the drive mechanism 4 includes a fixed frame 42 mounted on the mounting plate 2 and a cylinder 41 hinged to the fixed frame 42, the output end of which is connected to the hook mechanism 5. The cylinder 41 drives the hook mechanism 5 to swing.

[0035] In this embodiment, the hook mechanism 5 includes a swing rod 51, a hook 52, and a fixing block 53 disposed on the mounting plate 2. One end of the swing rod 51 is hinged to the fixing block 53, and the other end is connected to the hook 52. The output end of the cylinder 41 is hinged to the swing rod 51. The cylinder 41 is used to drive the swing rod 51 to swing so that the hook 52 hooks the handle 8 of the external frame box.

[0036] Specifically, when the cylinder 41 retracts, the control swing rod 51 swings clockwise, thereby driving the hook 52 to move upward. When the cylinder 41 extends, the control swing rod 51 swings counterclockwise, thereby driving the hook 52 to move downward. That is, when moving upward, the hook is released, and when moving downward, the handle 8 of the external frame box is fixed by the hook 52.

[0037] Preferably, the hook 52 is connected to the other end of the swing rod 51 via a pin 7. Connecting the hook 52 to the other end of the swing rod via the pin 7 facilitates unhooking.

[0038] More preferably, the mounting plate 2 is further provided with a limiting block 22, which is used to abut against the bottom of the swing rod 51 to limit the swing rod 51. By using the limiting block 22 to limit the swing rod 51, the hook 52 can be prevented from hitting the mounting plate 2 when the swing rod 51 swings counterclockwise.

[0039] Preferably, the fixing bracket 42 is detachably connected to the mounting plate 2. This detachable connection facilitates maintenance and replacement.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of the present utility model, and these improvements or modifications should also be considered within the protection scope of the present utility model.
