[0002] An AGV transport vehicle is a type of transport equipment that can automatically travel along a preset path and is commonly used for transporting materials in industrial production environments. It can transport goods from one location to another without the need for manual driving through various navigation technologies such as electromagnetic induction, laser navigation, and visual navigation. At the same time, in order to detect whether the goods are loaded on the fork arm, a cargo arrival detection device is also required. The Chinese patent with publication number CN217808599U discloses a cargo arrival detection mechanism and a fork with the detection mechanism, wherein the cargo arrival detection mechanism includes: a base, a sensor, a trigger assembly and a reset device, the sensor is arranged on the base, the trigger assembly is movably arranged on the base, the reset device is arranged between the trigger assembly and the base, and the sensor is arranged within the range of movement of the trigger assembly.

[0003] Regarding the disclosed technology, in the prior art, when the fork arm is inserting and removing the pallet, the pallet squeezes the trigger switch to determine whether the goods have reached the appropriate towing position. However, if the goods on the pallet exceed the area of ​​the pallet, the goods will first contact the surface of the transport vehicle before the pallet contacts the trigger switch. Before the pallet contacts the trigger switch, the goods will be touched and moved by the transport vehicle, which may cause the goods on the pallet to fall over, thereby affecting the transfer process of the goods.

[0004] For this purpose, a cargo arrival detection device and an AGV transport vehicle are proposed. Utility Model Content

[0005] The purpose of the present invention is to solve the problem that if the goods on the pallet exceed the area of ​​the pallet, the goods will first contact the surface of the transport vehicle before the pallet contacts the trigger switch. Before the pallet contacts the trigger switch, the goods will be touched and moved by the transport vehicle, which may cause the goods on the pallet to fall over, thereby affecting the transfer process of the goods. The present invention provides a cargo arrival detection device and an AGV transport vehicle.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0007] A cargo arrival detection device comprises a fork seat and a baffle, wherein a mounting assembly for mounting the baffle is provided on the surface of the fork seat, a double spring is fixedly connected to the surface of the fork seat, and one end of the double spring away from the fork seat is fixedly connected to the baffle, a trigger assembly for cargo arrival detection is provided on the surface of the fork seat and the surface of the baffle, a connecting assembly for protection is provided on the surface of the baffle, and a rubber protective pad is fixedly connected to the surface of the connecting assembly.

[0008] Furthermore, the mounting assembly includes an articulated seat, the surface of the fork seat is fixedly connected to the articulated seat by bolts, the inner wall of the articulated seat is hinged to a connecting piece by a hinge, and the baffle is fixedly connected to the connecting piece.

[0009] Furthermore, the trigger assembly includes a sensor, the surface of the fork seat is provided with the sensor, and the back side of the baffle is fixedly connected with a trigger block.

[0010] Furthermore, the connecting assembly includes a plug-in rail, the surface of the baffle is fixedly connected to the plug-in rail, the inner wall of the plug-in rail is movably plugged with a plug-in block, and the rubber protective pad is fixedly connected to the plug-in block.

[0011] Furthermore, there are two groups of double springs, and the two groups of double springs are symmetrically distributed on the surface of the fork seat.

[0012] An AGV transport vehicle comprises an AGV transport vehicle body, wherein a fork seat is arranged on the surface of the AGV transport vehicle body, and a double fork arm is fixedly connected to the surface of the fork seat.

[0013] The beneficial effects of the utility model are as follows:

[0014] When the utility model is transferring goods, if part of the structure of the goods is located outside the pallet, the goods will first come into contact with the rubber protective pad. When the squeezing force is transmitted to the baffle, the baffle flips over. At this time, the double springs will be squeezed and contracted, and the baffle drives the trigger block on the surface to approach the sensor on the surface of the fork seat. Because the baffle covers the surface of the fork seat, the problem of the goods first coming into contact with the surface of the transport vehicle will not occur at this time. When the trigger block comes into contact with the sensor, the sensor transmits a signal, accurately detecting that the pallet loaded with goods is in place, and the goods can be dragged. The rubber protective pad is connected to the baffle through the connecting assembly; at this time, if part of the structure of the goods is located outside the pallet, it can also effectively trigger the detection structure, so that the position of the goods on the pallet will not be moved, thereby avoiding the problem of the goods tipping over. At the same time, the surface of the goods can also be protected by the provision of the rubber protective pad that is easy to disassemble and assemble. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, when the baffle 4 is squeezed by the cargo or pallet, the baffle 4 can approach the trigger assembly 6, and then trigger the trigger assembly 6 to determine that the cargo has arrived at a suitable towing and transfer position.

[0027] like Figure 3 As shown, the trigger assembly 6 includes a sensor 601, the sensor 601 is provided on the surface of the fork seat 1, and the back of the baffle 4 is fixedly connected to a trigger block 602; specifically, the trigger assembly 6 is arranged so that when the trigger block 602 is moved by the baffle 4, the trigger block 602 contacts the surface of the sensor 601, and sends a signal to the control system of the transport vehicle, so that it can accurately detect that the pallet loaded with goods is in place and the pallet can be dragged and transferred.

[0028] like Figure 5 As shown, the connecting component 7 includes a rail 701, the surface of the baffle 4 is fixedly connected to the rail 701, the inner wall of the rail 701 is movably connected to the plug-in block 702, and the rubber protection pad 8 is fixedly connected to the plug-in block 702; specifically, the setting of the connecting component 7 is to install and connect the rubber protection pad 8 to the surface of the baffle 4, and the surface of the goods is protected by the rubber protection pad 8, so that when the goods are squeezed and contacted with the baffle 4, the surface of the goods will not be scratched, and the plug-in block 702 is connected to the rubber protection pad 8.

The rubber protection pad 8 is squeezed, and when the squeezing force is transmitted to the baffle 4, the baffle 4 cooperates with the connecting piece 302, and the connecting piece 302 rotates on the hinge seat 301, causing the baffle 4 to flip over. At this time, the double spring 5 will squeeze and contract, and the baffle 4 drives the trigger block 602 on the surface to approach the sensor 601 on the surface of the fork seat 1. Because the baffle 4 covers the surface of the fork seat 1, the problem of the goods first contacting the surface of the transport vehicle will not occur at this time. When the trigger block 602 contacts the sensor 601, the signal is transmitted through the sensor 601, and it is accurately detected that the pallet loaded with goods is in place, and the goods can be dragged. When the goods are not transferred, the rebound force of the double spring 5 makes the baffle 4 return to its original position, so that the sensor 601 and the trigger block 602 are separated. At the same time, the rubber protection pad 8 is connected to the baffle 4 through the connecting component 7. The rubber protection pad 8 can be installed or removed by pulling the plug block 702 and the plug rail 701.
