According to the utility model, the floating mechanism is arranged between the AGV chassis and the transportation top surface, the floating range of the floating mechanism is adjustable, and the floating mechanism can be locked, so that the self-adaptive floating at a butt-joint station can be ensured, and the driving error of the AGV is counteracted.

Description

Technical Field

[0001] The utility model belongs to the technical field of logistics automated transportation, and specifically relates to an adaptive floating positioning mechanism suitable for AGV. Background Art

[0002] AGV, short for "Automated Guided Vehicle," refers to a transport vehicle equipped with an automatic guidance system, such as electromagnetic or optical, that follows a prescribed path and features safety features and various transfer functions. AGVs can travel in all directions while operating autonomously, and both front and rear wheels can follow the guide line when turning, resulting in excellent maneuverability and suitability for working in narrow aisles.

[0003] When AGVs are used to transport and dock goods, the existing docking solution relies on the AGV's own docking to ensure accuracy. However, the AGV's own accuracy is limited and ultra-high-precision docking cannot be achieved. In some scenarios where ultra-high-precision docking is required, it can only be achieved by relying on limit pins, but occasionally there will still be inaccurate docking.

[0004] In some scenarios that require ultra-high driving progress, conventional AGVs cannot achieve high-precision driving, such as narrow aisles and long and narrow workstations. Utility Model Content

[0005] The purpose of the utility model is to provide an adaptive floating positioning mechanism suitable for AGV, which mainly solves the problem that the existing AGV trolley cannot load and unload goods and cannot achieve ultra-high precision docking.

[0006] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0007] An adaptive floating positioning mechanism suitable for AGV includes a lifting structure installed on the AGV trolley, a mounting plate fixed to the top of the lifting structure, a floating ball arranged on the mounting plate, a floating plate in contact with the top of the floating ball, a floating top plate fixed to the floating plate, and a driving mechanism fixedly connected to the mounting plate for driving the floating top plate.

[0008] Furthermore, in the present invention, the driving mechanism includes a mounting frame fixedly connected to the mounting plate, a driving motor arranged on the mounting frame, a driving gear connected to the motor, a screw rod arranged on the mounting frame and meshing with the driving gear through a driven gear, and a slider slidably connected to the screw rod and fixedly connected to the floating top plate.

[0009] Furthermore, in the present invention, a limiting rod is provided on the mounting plate below the floating plate, and waist-shaped holes are provided on the floating plate and the floating top plate for the limiting rod to pass through and achieve limiting.

[0010] Furthermore, in the present invention, a fixing block is provided below the middle portion of the floating top plate, and a clamping block is provided at a position of the mounting frame corresponding to the fixing block.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) The utility model provides a floating mechanism between the AGV chassis and the transport top surface. The floating range of the floating mechanism is adjustable and can also be locked to ensure that it can adaptively float at the docking station, offsetting the driving error of the AGV itself.

[0013] (2) In order to prevent the floating mechanism from shaking during transportation, the present invention provides a fixing block and a clamping block so that the floating mechanism can be locked by the clamping block. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0020] Example

[0021] like Figures 1 to 3As shown, the utility model discloses an adaptive floating positioning mechanism suitable for AGV, including a lifting structure 1 installed on the AGV trolley, a mounting plate 2 fixed to the top of the lifting structure 1, a floating ball 3 arranged on the mounting plate 2, a floating plate 4 in contact with the top of the floating ball 3, a floating top plate 5 fixed on the floating plate 4, and a driving mechanism fixedly connected to the mounting plate 2 for driving the floating top plate 5. Among them, the lifting structure is a conventional electric lifting structure, and those skilled in the art can choose according to actual conditions. This embodiment will not describe this structure in detail. The mounting plate is connected to the AGV chassis, and the floating top plate is connected to the upper mounting docking tooling. When docking the precision tooling, loosen the floating top plate, and the floating top plate can move freely. Then, through the guiding mechanism of the floating top plate, the material can be accurately confined to the specified position. At this time, even if there is an error in the docking of the AGV body, it will not affect the precise positioning of the upper mounting.

[0022] In this embodiment, the drive mechanism includes a mounting frame 6 fixedly connected to the mounting plate 2, a drive motor 7 mounted on the mounting frame 6, a drive gear 8 connected to the motor, a screw 10 mounted on the mounting frame 6 and meshing with the drive gear 8 via a driven gear 9, and a slider 11 slidably connected to the screw 10 and fixedly connected to the floating roof plate 5. During loading and unloading, the drive gear 8 connected to the motor drives the driven gear 9, causing the slider 11 on the screw 10 to move the floating roof plate 5 on the floating balls 3, thereby precisely confining the materials to a specified position.

[0023] In this embodiment, in order to prevent the floating top plate from shaking significantly, a limiting rod 12 is provided on the mounting plate 2 below the floating plate 4, and waist-shaped holes 13 are provided on the floating plate 4 and the floating top plate 5 for the limiting rod 12 to pass through and achieve limiting.

[0024] In this embodiment, the floating roof panel mounted on top can cause the AGV to wobble from side to side during travel. To prevent this, a clamping mechanism clamps the floating roof panel to prevent it from swaying. The clamping mechanism includes a fixed block 14 positioned below the center of the floating roof panel 5 and a clamping block 15 positioned on the mounting frame 6 at a location corresponding to the fixed block. The clamping mechanism can be driven by a motor and a screw, or manually locked.

[0025] Through the above design, the utility model establishes a floating mechanism between the AGV chassis and the transport top surface. The floating range of the floating mechanism is adjustable and can also be locked, ensuring that it can adaptively float at the docking station, offsetting the driving error of the AGV itself.

[0026] The above embodiment is only one of the preferred implementation methods of the present invention and should not be used to limit the scope of protection of the present invention. Any changes or modifications that have no substantive meaning made to the main design concept and spirit of the present invention, as long as the technical problems they solve are still consistent with the present invention, should be included in the scope of protection of the present invention.
