Description

Technical Field

[0001] The utility model relates to the technical field of AGV trolleys, in particular to an AGV cargo travel switch protection device. Background Art

[0002] With the development of science and technology, all walks of life, especially labor-intensive enterprises, have higher and higher requirements for factory automation. AGV trolleys were born, which are responsible for the transportation of products, semi-finished products and raw materials. AGV trolleys are equipped with automatic guidance devices such as electromagnetic or optical devices, which can travel along the specified guidance path and have safety protection and various transfer functions.

[0003] In order to make full use of the available space, storing raw materials, semi-finished products and finished products on multi-layer shelves has become the preferred choice of most companies. In order to apply AGV carts to multi-layer shelves and improve factory automation, the patent document with publication number CN210027181U: AGV cart, an AGV cart with a lifting system is used in multi-layer shelves, and a micro-travel switch is provided on the lifting system for position detection.

[0004] However, when the existing AGV cargo travel switch is pressed down, the shelf at the same height as the travel switch often collides with the travel switch. In order to avoid damage to the travel switch after multiple collisions, a baffle is installed on the travel switch to move with the travel switch. Since the baffle itself is heavy and the spring force on the rotating shaft is small, the AGV cart often cannot lift the cargo travel switch after unloading. As a result, the cargo switch always shows the cargo status. The car's task cannot be completed normally, blocking other AGV carts, causing serious traffic jams. Utility Model Content

[0005] The utility model aims to solve the problem in the prior art that, due to the heavy weight of the baffle itself, the AGV trolley often cannot lift the cargo travel switch after unloading, resulting in the cargo switch always showing a cargo-in state and the trolley's task cannot be completed normally. An AGV cargo travel switch protection device with self-rebound is provided.

[0006] The technical solution adopted by the utility model is as follows:

[0007] An AGV cargo travel switch protection device includes a base, a through slot capable of accommodating a travel switch is provided on the base, a mounting plate is provided on the base, and an elastic plate is provided, one end of the elastic plate is a connecting portion, the connecting portion is connected to the mounting plate, the middle portion of the elastic plate is a deformation portion, and when not subjected to external force, the deformation portion bulges to one side and is above the through slot. Through the mounting plate provided on the base and the elastic plate with one side bulging, when the AGV vehicle moves toward the shelf, the shelf abuts against the elastic plate, and then the deformation portion of the elastic plate is deformed, and the bulge of the deformation portion moves toward the travel switch to press down the travel switch, and when the elastic plate is separated from the shelf, the elastic plate rebounds to the initial state by itself, thereby avoiding the problem that the baffle installed on the travel switch moves with the travel switch and the AGV vehicle often cannot lift the cargo travel switch after unloading due to the heavy weight of the baffle itself and the small spring force on the rotating shaft, and the accuracy of the travel switch can be improved under the premise of reducing the risk of damage to the travel switch.

[0008] Preferably, a first receiving groove is provided on one side of the mounting plate, the connecting portion is provided in the first receiving groove, and the connecting portion is bolted to the mounting plate. By providing the first receiving groove and the connecting portion being bolted to the mounting plate, when removing the elastic plate, the bolts between the connecting portion and the mounting plate can be directly removed to remove the elastic plate without removing the mounting plate or the bottom plate.

[0009] Preferably, the other end of the elastic plate is a guide portion, the base is further provided with a guide plate, the guide plate is provided with a second receiving groove, the guide portion is provided in the second receiving groove and can move relative to the second receiving groove. By providing the guide portion, the guide plate and the second receiving groove, the elastic plate can be deformed in the length direction under the action of the second receiving groove during the deformation of the elastic plate.

[0010] Preferably, a safety plate is also provided on the base, and the safety plate is provided on a side of the mounting plate away from the through slot, and the side end surface of the safety plate can abut against the connection part. By providing the safety plate, after the bolts at the connection part and the mounting plate fail after a period of use, the safety plate can limit the movement of the elastic plate, thereby ensuring the stability of the AGV during operation.

[0011] Preferably, a limit plate is fixedly arranged on the base, and the limit plate is arranged on the side of the guide plate away from the through slot, and the side end surface of the limit plate can abut against the guide portion. By setting the limit plate, when the shelf abuts against the elastic plate, the deformation of the elastic plate will not be too large, and the service life of the elastic plate is increased under the premise of ensuring the trip switch is triggered.

[0012] Preferably, the elastic plate is made of spring steel, which can ensure long-term stable use.

[0013] It can be seen from the above technical scheme that the advantages of the utility model are: through the mounting plate set on the base and the elastic plate protruding on one side, when the AGV car moves to the shelf, the shelf abuts against the elastic plate, and then the deformation part of the elastic plate is deformed, and the protrusion of the deformation part moves toward the travel switch to press the travel switch. When the elastic plate is separated from the shelf, the elastic plate rebounds to the initial state by itself, avoiding the problem that the baffle installed on the travel switch moves with the travel switch and the AGV car often cannot lift the cargo travel switch after unloading due to the heavy weight of the baffle itself and the small spring force on the rotating shaft. The accuracy of the travel switch can be improved under the premise of reducing the risk of damage to the travel switch. Through the first accommodating groove and the connecting part connected to the mounting plate bolt connection, when the elastic plate is disassembled, the bolts at the connecting part and the mounting plate can be directly removed to realize the removal of the elastic plate without disassembling the mounting plate or the bottom plate. Through the guide part, the guide plate and the second accommodating groove, the deformation direction of the elastic plate can be deformed along the length direction under the action of the second accommodating groove during the deformation of the elastic plate. The safety plate can limit the movement of the elastic plate after the bolts at the connection part and the mounting plate fail after a long period of use, thus ensuring the stability of the AGV during operation. The limit plate can prevent the deformation of the elastic plate from being too large when the shelf contacts the elastic plate, thus increasing the service life of the elastic plate while ensuring the trip switch is triggered. The elastic plate made of spring steel can ensure long-term stable use. BRIEF DESCRIPTION OF THE DRAWINGS
