Description

Technical Field

[0001] This utility model relates to the field of automotive testing equipment, specifically a flatbed AGV for whole vehicle testing. Background Technology

[0002] AGVs are automated guided vehicles used in the automotive inspection process. They are automated transport equipment equipped with electromagnetic, optical, and other automatic guidance devices, capable of traveling along a predetermined path and possessing safety protection and transfer functions. During automotive inspection, AGVs can automatically transport vehicles or parts to be inspected to various inspection stations according to preset programs and instructions, completing different inspection tasks such as dimensional inspection, appearance inspection, and performance inspection. For example, Huasheng Measurement's intelligent inspection solution for automotive bodies and doors utilizes a high-performance laser tracker deeply integrated with AGVs, collaborative robots, and 5G wireless communication technology. Through the flexibility of AGVs and collaborative robots, rapid scanning and inspection of large-sized components and parts such as automotive bodies and doors can be achieved. When the AGV for vehicle inspection moves to the assembly position, the wheels at its bottom support the AGV, which is prone to shaking. This directly affects the stability and positioning accuracy of the AGV. If it is carrying the vehicle to be inspected or heavy parts, the shaking may cause the workpiece to shift or tip over, resulting in property damage such as vehicle scratches and parts damage. In severe cases, it may also endanger the safety of nearby operators. Utility Model Content

[0003] The purpose of this invention is to provide an AGV (Automated Guided Vehicle) for vehicle inspection, in order to solve the problems mentioned in the background section.

[0004] To achieve the above objectives, a vehicle inspection flatbed AGV is provided, comprising an inspection AGV, wherein a fixing plate is fixedly installed on the bottom of the inspection AGV, and wheel lifting assembly A and wheel lifting assembly B are respectively installed on the bottom surface of the inspection AGV. Wheel lifting assembly B includes a mounting platform fixedly connected inside the inspection AGV, and ground anchors are fixedly inserted on the mounting platform. At the same time, the surface of the mounting platform is covered with a seesaw lifting assembly, which consists of a drive plate, a fulcrum shaft, and a wheel mounting plate.

[0005] Furthermore, the wheel lifting assembly A and the wheel lifting assembly B have the same structure, and both wheel lifting assembly A and wheel lifting assembly B are equipped with a wheel mechanism. At the same time, the wheel mechanisms on wheel lifting assembly A and wheel lifting assembly B are diagonally distributed at the bottom of the detection AGV.

[0006] Furthermore, the wheel lifting assembly B also includes a drive motor, a reducer, a drive gear, a drive gear, and a wheel mechanism, and the output end of the drive motor is equipped with a reducer, and the output shaft of the reducer is fixedly mounted with a drive gear.

[0007] Furthermore, a drive gear is mounted on one side of the drive gear, and the size of the drive gear is adapted to that of the drive gear. At the same time, the drive gear is meshed with the drive gear, and the drive gear is mounted on the right side of the mounting platform through a bearing seat.

[0008] Furthermore, a lead screw is installed on the shaft of the drive gear, and a drive plate is installed on the upper side of the drive gear. At the same time, a wheel mounting plate is fixedly installed at the end of the drive plate. A fulcrum shaft is inserted between the wheel mounting plate and the drive plate. The fulcrum shaft is movably mounted on the mounting platform through a bearing seat.

[0009] Furthermore, four sets of ground anchors are installed at equal intervals on the mounting platform, and the four sets of ground anchors are distributed in a rectangular pattern.

[0010] Furthermore, a wheel mechanism is installed at the bottom of the wheel mounting plate, and the wheel mechanism consists of omnidirectional wheels and idler wheels.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This solution involves using an AGV to transport automotive parts to a designated trough for assembly. First, the AGV moves to the edge of the trough. Then, the wheel mechanism on the AGV guides the four sets of ground anchors at the bottom of the AGV to the ground anchor holes. Simultaneously, the two sets of wheel mechanisms at the bottom of the AGV are raised by the wheel lifting component B, and the ground anchors on the AGV descend to the ground anchor holes for positioning. This ensures the stability of the equipment or parts carried by the AGV after they have been moved to the designated position, preventing any shaking. The fit between the ground anchor and the hole can reduce positioning errors and ensure that the automotive parts carried by the AGV, such as the body frame and powertrain, can be fully aligned with the assembly stations in the ground groove, such as tooling fixtures and docking interfaces, avoiding problems such as assembly misalignment and parts collision caused by AGV displacement.

Detailed Implementation

[0014] Please see Figure 1-4 This utility model provides a vehicle inspection flatbed AGV, including an inspection AGV 100. A fixing plate 200 is fixedly installed on the bottom of the inspection AGV 100, and a wheel lifting assembly A300 and a wheel lifting assembly B400 are respectively installed on the bottom surface of the inspection AGV 100. The wheel lifting assembly B400 includes a mounting platform 409 fixedly connected inside the inspection AGV 100, and a ground anchor 4091 is fixedly inserted on the mounting platform 409. At the same time, the surface of the mounting platform 409 is covered with a seesaw lifting assembly, which consists of three parts: a driving plate 405, a fulcrum shaft 406, and a wheel mounting plate 407.

[0015] In a preferred embodiment, the wheel lifting assembly A300 and the wheel lifting assembly B400 have the same structure, and both the wheel lifting assembly A300 and the wheel lifting assembly B400 are provided with a wheel mechanism 408. At the same time, the wheel mechanisms 408 on the wheel lifting assembly A300 and the wheel lifting assembly B400 are diagonally distributed at the bottom of the detection AGV100.

[0016] The wheel lifting assembly B400 also includes a drive motor 401, a reducer 402, a drive gear 403, a drive gear 404, and a wheel mechanism 408. The reducer 402 is installed at the output end of the drive motor 401, and the drive gear 403 is fixedly installed on the output shaft of the reducer 402.

[0017] A drive gear 404 is mounted on one side of the drive gear 403, and the size of the drive gear 404 is compatible with that of the drive gear 403. The drive gear 404 is meshed with the drive gear 403 and is mounted on the right side of the mounting platform 409 via a bearing seat.

[0018] The seesaw lifting assembly consists of three parts: a drive plate 405, a fulcrum shaft 406, and a wheel mounting plate 407. When the drive plate 405 moves upward, the wheel mounting plate 407 moves downward; conversely, when the drive plate 405 moves downward, the wheel mounting plate 407 moves upward. The lifting mechanism of the drive plate 405 is as follows: the drive motor 401 drives the drive gear 403 to rotate through the reducer 402, and the drive gear 403 drives the drive gear 404 to rotate. A lead screw is installed on the shaft of the drive gear 404, and a drive seat is screwed to the outside of the lead screw. The drive seat can be connected to the drive plate 405 through a hinge assembly to realize the lifting operation of the drive plate 405.

[0019] A lead screw is mounted on the shaft of the drive gear 404, and a drive plate 405 is mounted on the upper side of the drive gear 404. At the same time, a wheel mounting plate 407 is fixedly provided at the end of the drive plate 405. A fulcrum shaft 406 is inserted between the wheel mounting plate 407 and the drive plate 405. The fulcrum shaft 406 is movably mounted on the mounting platform 409 through a bearing seat.

[0020] like Figure 1-4As shown: The wheel mechanism 408 first guides the AGV to the coarse positioning range at the edge of the trench to prevent the AGV from shifting as a whole; after the four sets of ground anchors 4091 are inserted into the ground anchor holes, the AGV is rigidly locked to the ground. Compared with traditional wheeled parking, which is prone to displacement due to uneven ground or inertia, the cooperation between the ground anchors 4091 and the holes can reduce positioning errors and ensure that the automotive parts carried by the AGV, such as the body frame and powertrain, and other high-precision components, can be perfectly aligned with the assembly stations in the trench, such as tooling fixtures and docking interfaces. To avoid assembly misalignment and parts collision caused by AGV displacement, the combination of the B400 wheel lifting assembly, the 408 wheel lifting mechanism, and the 4091 ground anchors solves the stability problem of traditional wheeled AGVs from the perspective of support structure: when traditional AGVs rely on wheels for support, the wheels are in point contact with the ground, and the wheel set has a certain degree of elastic deformation. When carrying heavy components, such as car chassis, the weight can reach hundreds of kilograms, which can easily cause slight swaying due to uneven force. The four sets of ground anchors 4091 provide stable support. The ground anchor 4091 becomes the rigid support point for the AGV, and the wheel body is lifted off the ground, eliminating the influence of elastic deformation of the wheel body. The AGV as a whole forms a stable planar support with the ground through the ground anchor 4091, which can completely eliminate the horizontal swaying or vertical settlement of the AGV during the assembly process. It is especially suitable for high-precision docking in the assembly of automotive parts, such as bolt hole alignment and pipe insertion. In traditional AGVs, the wheels need to bear the weight of the AGV and the weight of the parts for a long time during operation. If there are small impurities on the ground, such as metal chips and screws, the wheels will wear faster. This design reduces the wear of the wheels by lifting the wheels: when the AGV is working in the designated trench position, the wheel mechanism 408 is lifted off the ground by the wheel lifting component B400. At this time, the weight of the AGV is completely borne by the ground anchor, and the wheels are no longer under force, which can avoid static wear of the wheels during operation. After the wheels are lifted off the ground, they will not come into direct contact with ground impurities, reducing the risk of wheel scratches and jamming, extending the replacement cycle of vulnerable parts such as wheels and bearings, and reducing the maintenance cost of the AGV.

[0021] In a preferred embodiment, four sets of ground anchors 4091 are installed at equal intervals on the mounting platform 409, and the four sets of ground anchors 4091 are arranged in a rectangular pattern.

[0022] A wheel mechanism 408 is installed at the bottom of the wheel mounting plate 407, and the wheel mechanism 408 consists of a caster wheel and an idler wheel.

[0023] Working Principle: During use, the AGV100 transports automotive parts to a designated assembly location in the trench. First, the AGV100 moves to the edge of the trench. The wheel mechanism 408 on the AGV100 guides the four sets of ground anchors 4091 at the bottom of the AGV100 into the ground anchor holes. Simultaneously, the two sets of wheel mechanisms 408 at the bottom of the AGV100 rise under the action of the wheel lifting assembly B400, causing the ground anchors 4091 on the AGV100 to descend and position themselves in the anchor holes, ensuring the AGV100 is properly positioned. 0. The stability of the mounted equipment or parts after moving to the designated position is guaranteed, and there will be no shaking. The wheel lifting assembly B400 works in the same way as the wheel lifting assembly A300. It detects a set of wheel lifting devices at each end of the AGV100. The wheel mechanism 408 is raised and lowered by the drive motor 401, reducer 402, drive gear 403, drive gear 404, drive plate 405, fulcrum shaft 406, and wheel mounting plate 407. The wheel lifting assembly A300 is similar to a seesaw structure. One side of the wheel mechanism 408 is a universal wheel, and the other side is an idler wheel.
