Description

Technical Field

[0001] The present invention belongs to the technical field of AGV equipment, and in particular, the present invention relates to a dump bucket AGV and a method for using the same. Background Art

[0002] In traditional logistics operations, AGVs typically handle and transfer materials using flatbed loaders, forklifts, or conveyor belts. However, traditional AGVs have numerous limitations when handling bulk materials such as coal, ore, grain, and chemical raw materials, as well as various granular and powdered materials.

[0003] While some existing skip-type handling equipment has unloading capabilities, it suffers from deficiencies in structural design and intelligent control. Some skip structures lack stability, making them prone to loosening and deformation during frequent loading and unloading, impacting the equipment's service life and operational safety. Furthermore, traditional skip-type handling equipment lacks intelligent features like navigation, obstacle avoidance, and path planning, making it difficult to adapt to complex and changing industrial environments and unable to meet the demands of modern intelligent manufacturing for efficient, precise, and intelligent logistics handling equipment. Summary of the Invention

[0004] The present invention is developed to solve the above-mentioned problems, and its purpose is to provide a tipping AGV with automatic obstacle avoidance, precise navigation, and stable flipping, and a method of using the same. In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a tipping AGV, comprising a welded frame, a drive structure is provided at the bottom of the welded frame, and a tipping assembly is provided on the welded frame.

[0005] The tipping bucket assembly includes a tipping bucket and a tipping bucket electric cylinder. The tipping bucket electric cylinder is arranged at the bottom of the welding frame. The welding frame has a first through slot. The telescopic rod of the tipping bucket electric cylinder passes through the first through slot and is connected to one end of the tipping bucket. The other end of the tipping bucket is rotatably connected to the welding frame.

[0006] A fixing plate is provided on the welding frame, a first shock-absorbing pad is provided on the fixing plate, a structural reinforcement plate is provided at the bottom of the tipping hopper, and the tipping hopper is connected to the welding frame through a hinge.

[0007] The driving structure includes a first omnidirectional steering wheel, a second omnidirectional steering wheel and a mounting frame. One end of the welded frame is connected to a mounting frame. The first omnidirectional steering wheel is symmetrically arranged at the bottom of the welded frame. The mounting frame is arranged in the mounting frame. The second omnidirectional steering wheel is symmetrically arranged on the mounting frame. A seesaw assembly is arranged between the mounting frame, the welded frame and the mounting frame.

[0008] The seesaw assembly includes a rotating shaft, one end of which is arranged on a welding frame, and the other end of which is connected to a mounting frame. The rotating shaft is fixedly connected to the mounting frame, L-shaped plates are arranged on both sides of the mounting frame, and limiting plates are arranged on both sides of the mounting frame.

[0009] A housing cover assembly is provided on the welding frame, wherein the housing cover assembly includes a housing cover, the housing cover is connected to the welding frame, the driving structure is located in the housing cover, and an edge-touching anti-collision strip is provided on the housing cover.

[0010] The electronic control component includes an obstacle avoidance radar, a navigation radar, a control panel and an emergency stop switch. The obstacle avoidance radar is arranged at the corner of the casing cover. The casing cover is provided with an electric control cabinet, a control panel and an emergency stop switch. The navigation radar is arranged on the electric control cabinet. The obstacle avoidance radar, navigation radar, control panel and emergency stop switch are connected to a PLC controller. The power distribution line in the electric control cabinet is connected to the first omnidirectional steering wheel, the second omnidirectional steering wheel and the tipping bucket electric cylinder, and the power distribution line is connected to a power supply component.

[0011] The power supply assembly includes a fixing bracket and a battery. The fixing bracket is arranged at the bottom of the welding frame. The battery is arranged on the fixing bracket. The battery is connected to the power distribution line.

[0012] The tipping hopper includes a bottom plate, first vertical plates are provided on both sides of the bottom plate, a second vertical plate is provided at one end of the bottom plate, and an inclined plate is provided at the other end of the bottom plate, and a receiving cavity is formed between the bottom plate, the first vertical plate, the second vertical plate and the inclined plate.

[0013] A method for using a dump bucket AGV, specifically:

[0014] Step 101: Start the AGV by pressing the start button on the control panel. The AGV enters the standby state.

[0015] Step 102: Set the AGV's driving path and destination through the control panel;

[0016] Step 103: When the AGV reaches the designated unloading location, the PLC controller drives the electric cylinder to start, and the telescopic rod of the electric cylinder drives the bucket to rotate and unload the material smoothly; after the material is unloaded, the electric cylinder retracts in the opposite direction, returning the bucket to its initial horizontal state;

[0017] Step 104: The AGV returns to the starting position or goes to the next task location according to the preset path according to the PLC controller.

[0018] The technical effect of this invention is that before the AGV starts, the operator first sets the AGV's operating parameters, such as the route, destination, and dump instructions, through the control panel. This information is then transmitted to the PLC controller for storage. Simultaneously, the battery supplies power to the electrical control cabinet via the distribution line, preparing the AGV for operation.

[0019] After the AGV starts, the navigation radar begins acquiring real-time location information and continuously feeds it back to the PLC controller. Based on the preset path and current location, the PLC calculates the AGV's direction and speed adjustment instructions. These instructions are then sent to the first and second omnidirectional steering wheels via the power distribution circuits within the electrical control cabinet, controlling the AGV's trajectory along the preset path.

[0020] During operation, the obstacle avoidance radar continuously scans the AGV's surroundings. Once an obstacle is detected, it immediately sends an obstacle signal to the PLC controller. The PLC quickly analyzes and processes the signal, generating appropriate obstacle avoidance control instructions based on the obstacle's location, distance, and the AGV's current driving state. The control cabinet then transmits these instructions to the first and second omnidirectional steering wheels, enabling the AGV to safely avoid the obstacle and resume normal operation.

[0021] When the AGV reaches the designated unloading location, the PLC controller sends a start signal to the tipping cylinder through the electrical control cabinet according to the preset unloading instructions. Upon receiving the signal, the tipping cylinder extends its telescopic rod, rotating the tipping hopper and smoothly unloading the material. After unloading, the PLC controller sends a reverse retraction signal, and the tipping hopper, under its own weight, returns to its initial horizontal position. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following is a further detailed description of the specific implementation methods of the present invention through the description of the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0030] like Figures 1 to 5 As shown, a tipping AGV comprises a welded frame 1, a drive structure 2 disposed at its base, and a tipping assembly 3 mounted on the welded frame 1. The welded frame 1 is a flat plate with triangular plates attached to its sides to reinforce its lateral strength. The back of the plate is connected to a cross plate to strengthen the back structure of the welded frame 1, serving as the core load-bearing structure of the AGV. The bottom of the welded frame 1 is connected to the drive structure 2, which enables the AGV to move forward, backward, and turn. The tipping assembly 3 accommodates and unloads materials.

[0031] The tipping bucket assembly 3 includes a tipping bucket 31 and a tipping bucket electric cylinder 301. The tipping bucket electric cylinder 301 is arranged at the bottom of the welding skeleton 1. The welding skeleton 1 has a first through slot 302. The telescopic rod of the tipping bucket electric cylinder 301 passes through the first through slot 302 and is connected to one end of the tipping bucket 31. The other end of the tipping bucket 31 is rotatably connected to the welding skeleton 1. The tipping bucket electric cylinder 301 is fixed to the welding skeleton 1 by bolts. The tipping bucket electric cylinder 301 is provided with an overload protector to prevent overloading. The telescopic rod of the tipping bucket electric cylinder 301 extends out of the first through slot 302 and is connected to one end of the tipping bucket 31. A fixed seat is provided at the bottom of the tipping bucket 31. The fixed seat is connected to a fixed rod. The end of the telescopic rod of the tipping bucket electric cylinder 301 is sleeved on the fixed rod. At the same time, both sides of the telescopic rod are against the fixed seat to achieve a fixed connection between the telescopic rod and the tipping bucket 31. The other end of the tipping bucket 31 is rotatably connected to the welding skeleton 1. On the skeleton 1, after the bucket electric cylinder 301 is started, the telescopic rod of the bucket electric cylinder 301 extends or retracts, driving the bucket hopper 31 to flip. When the AGV travels to the designated unloading location, the bucket electric cylinder 301 is started, the telescopic rod of the bucket electric cylinder 301 extends, pushing the bucket hopper 31 to rotate around the hinge 101, so that the material is unloaded from the bucket hopper 31; after the material is unloaded, the bucket electric cylinder 301 retracts in the opposite direction, and at the same time, the weight of the bucket hopper 31 drives the bucket hopper 31 to return to its initial horizontal state, ready for the next loading.

[0032] A fixed plate 4 is provided on the welded frame 1, and a first shock-absorbing pad 401 is provided on the fixed plate 4. A structural reinforcement plate 316 is provided at the bottom of the tipping hopper 31, and the tipping hopper 31 is connected to the welded frame 1 via a hinge 101. The fixed plate 4 and the welded frame 1 are an integrally formed structure, and the fixed plate 4 is symmetrically arranged on the welded frame 1. The first shock-absorbing pad 401 provided on the fixed plate 4 absorbs the impact force generated by the movement of the tipping hopper 31 when the tipping hopper 31 returns to its initial horizontal state, thereby reducing vibration and ensuring the stability of the AGV operation and the service life of the components. The bottom of the tipping hopper 31 is connected to the structural reinforcement plate 316. When the tipping hopper 31 is loaded with materials, the weight of the materials will be concentrated on the bottom. The structural reinforcement plate 316 is installed at the bottom connection structure to disperse the pressure caused by the weight of the materials and avoid deformation, cracking and other problems caused by excessive local force on the bottom. When transporting heavy materials.

[0033] The drive structure 2 includes a first omnidirectional steering wheel 201, a second omnidirectional steering wheel 202, and a mounting frame 203. A mounting frame 204 is connected to one end of the welded frame 1. The first omnidirectional steering wheel 201 is symmetrically arranged at the bottom of the welded frame 1. The mounting frame 203 is arranged within the mounting frame 204. The second omnidirectional steering wheel 202 is symmetrically arranged on the mounting frame 203. A seesaw assembly 5 is arranged between the mounting frame 203, the welded frame 1, and the mounting frame 204. The mounting frame 204 is welded to the welded frame 1. The first omnidirectional steering wheel 201 is symmetrically fixed to the bottom of the welded frame 1. The mounting frame 203 is arranged within the mounting frame 204. The second omnidirectional steering wheel 202 is symmetrically mounted on the mounting frame 203. The mounting frame 203 is a square plate with two square slots for mounting the second omnidirectional steering wheel 202. The mounting frame 203 is connected to the mounting frame 204 through the seesaw assembly 5. The setting of the first omnidirectional steering wheel 201 and the second omnidirectional steering wheel 202 allows the AGV to move. The second omnidirectional steering wheel 202 is fixedly connected to the mounting frame 203. The seesaw assembly 5 is set on the mounting frame 203. When the AGV travels on an uneven road surface, the mounting frame 203 rotates with the seesaw assembly 5, so that the second omnidirectional steering wheel 202 always sticks to the ground and maintains stable driving.

[0034] The seesaw assembly 5 includes a rotating shaft 501, one end of which is attached to the welded frame 1 and the other end is connected to the mounting frame 204. The rotating shaft 501 is fixedly connected to the mounting frame 203. L-shaped plates 502 are provided on either side of the mounting frame 204, and limit plates 503 are provided on either side of the mounting frame 203. A mounting base for the rotating shaft 501 is provided on the welded frame 1 and the mounting frame 204. The mounting base comprises a base plate with a semicircular fixing plate threaded onto it. A bearing is provided within the semicircular fixing plate, and the rotating shaft 501 is welded to the mounting frame 203. When the AGV travels on uneven surfaces, the mounting frame 203 rotates about the rotating shaft 501, ensuring that the second omnidirectional steering wheel 202 maintains contact with the ground, maintaining stable driving.

[0035] The welded frame 1 is provided with an organic housing cover assembly 6, which includes a housing cover 601 connected to the welded frame 1. The drive structure 2 is located within the housing cover 601, and the housing cover 601 is provided with an edge collision prevention strip 602. The housing cover 601 is bolted to the welded frame 1, forming a cavity between the housing cover 601 and the welded frame 1. The drive structure 2 and other structures are located within the cavity. The housing cover 601 protects the internal components. The housing cover 601 is provided with an edge collision prevention strip 602. The edge collision prevention strip 602 can buffer and trigger a signal when the AGV encounters an obstacle, preventing collision damage.

[0036] The electronic control assembly 7 includes an obstacle avoidance radar 701, a navigation radar 702, a control panel 703, and an emergency stop switch 704. The obstacle avoidance radar 701 is mounted in a corner of the housing cover 601. The housing cover 601 is also equipped with an electrical control cabinet 705, a control panel 703, and an emergency stop switch 704. The navigation radar 702 is mounted on the electrical control cabinet 705. The obstacle avoidance radar 701, navigation radar 702, control panel 703, and emergency stop switch 704 are connected to a programmable logic controller (PLC). The power distribution circuit within the electrical control cabinet 705 connects the first and second omnidirectional steering wheels 201, 202, and the bucket electric cylinder 301. This power distribution circuit is also connected to the power supply assembly 8. The obstacle avoidance radar 701, mounted in a corner of the housing cover 601, transmits and receives electromagnetic waves to scan the environment within a certain range around the AGV in real time. If the obstacle avoidance radar 701 detects an obstacle within the set safety distance, it immediately generates an obstacle signal and quickly transmits this signal to the PLC controller, ensuring safe operation of the AGV.

[0037] Navigation radar 702, mounted on electrical control cabinet 705, primarily facilitates AGV navigation. It receives signals from the ground or other positioning systems and, combined with pre-set map data, accurately and in real time obtains information such as the AGV's position, direction, and speed. This positional information is fed back to the PLC controller, which compares and analyzes it against the pre-set route to determine if the AGV has deviated from its route. The controller then adjusts control instructions accordingly, guiding the AGV along the correct path and ensuring it reaches its destination accurately.

[0038] The control panel 703 is mounted in a convenient location on the housing cover 601. It serves as the operator's interface for interacting with the AGV. Using buttons and displays on the control panel 703, the operator can input AGV operating parameters, set the route, specify the destination, set dump instructions, and adjust the operating speed. These input commands are converted into electrical signals and transmitted to the PLC controller, which then controls and adjusts the AGV's operation accordingly.

[0039] The emergency stop switch 704 is also mounted in a conveniently accessible location on the housing cover 601. In the event of an emergency during AGV operation, such as equipment failure or a serious obstacle that cannot be avoided normally, the operator can quickly press the emergency stop switch 704. Once triggered, the emergency stop switch 704 immediately sends an emergency stop signal to the PLC controller. Upon receiving the signal, the PLC controller immediately cuts off the power supply to the first and second omnidirectional steering wheels 201, 202, and the dump bucket electric cylinder 30, bringing the AGV to a rapid halt and preventing accidents.

[0040] The PLC controller is the core control unit of the entire electronic control component 7, which is set inside the electric control cabinet 705. The PLC controller is connected to the host computer. The PLC controller can receive task instructions sent by the host computer in real time, and at the same time receive various signals from the obstacle avoidance radar 701, navigation radar 702, control panel 703 and emergency stop switch 704, and perform logical processing and analysis on these signals. The PLC controller generates corresponding control instructions and then sends these instructions to the distribution lines in the electric control cabinet 705, thereby controlling the operation of the first omnidirectional steering wheel 201, the second omnidirectional steering wheel 202 and the tipping bucket electric cylinder 301, thereby realizing precise control of the AGV's driving, steering, unloading and other actions.

[0041] The electrical control cabinet 705 is mounted on the housing 601. It integrates complex power distribution circuits and electrical components. It receives electrical energy from the power supply assembly 8 and distributes it through internal distribution circuits to power components such as the first omnidirectional steering wheel 201, the second omnidirectional steering wheel 202, and the bucket electric cylinder 301, providing power support for their operation. The electrical control cabinet 705 is also responsible for transmitting control signals from the PLC controller, ensuring that each component operates accurately according to instructions, and protecting the circuits to ensure the safe and stable operation of the entire electronic control system.

[0042] The power supply assembly 8 includes a fixed bracket 801 and a battery 802. The battery 802 is mounted on the fixed bracket 801 and connected to the power distribution line. The fixed bracket 801 fixes the battery 802 to the fixed bracket 801. The fixed bracket 801 has a square slot formed therein, and the battery 802 is placed in the square slot to power the various components.

[0043] The tipping hopper 31 includes a base plate 311, with first vertical plates 312 disposed on either side of the base plate 311, a second vertical plate 313 disposed at one end of the base plate 311, and an inclined plate 314 disposed at the other end. A receiving cavity 315 is formed between the base plate 311, the first vertical plates 312, the second vertical plates 313, and the inclined plate 314. The base plate 311, the first vertical plates 312, the second vertical plates 313, and the inclined plate 314 form the receiving cavity 315. Material is placed in the receiving cavity 315. When it is time to unload, the material slides out along the inclined plate 314, which forms a 30-degree angle with the horizontal plane to facilitate material discharge.

[0044] A method for using a dump bucket AGV, specifically:

[0045] Step 101, before starting the AGV, the AGV enters the standby state; through the control panel 703 of the AGV, the equipment self-checking mode is entered, the obstacle avoidance radar 701 detection option is selected, an analog obstacle is placed in different positions within the effective detection range of the obstacle avoidance radar 701, and whether the obstacle avoidance radar 701 can detect the obstacle in time. A simple short-distance driving path is set through the control panel 703, the AGV is started, it is observed whether the navigation radar 702 can obtain the position information of the AGV in real time, and accurately display the current position of the AGV on the map interface of the control panel 703, in the process of AGV driving, a slight route deviation is artificially made, it is checked whether the navigation radar 702 can detect the position deviation in time, and feedback the information to the PLC controller, so that the AGV can automatically adjust the driving direction according to the preset navigation algorithm, and return to the correct path. The emergency stop switch 704 is pressed, it is observed whether the AGV can immediately stop running, and whether all power components are powered off and stopped working. In the AGV power-off state, the first omni-directional rudder wheel 201 and the second omni-directional rudder wheel 202 are manually rotated, and it is felt whether the resistance during rotation is uniform, and whether there is jamming or abnormal sound. After the check is correct, the start button on the control panel 703 is pressed, and the AGV enters the standby state;

[0046] Step 102, the driving path and destination of the AGV are set through the control panel 703; by clicking the starting point on the map, the point will be selected and marked by the system at this time, and then the nodes such as turning points and fork junctions along the expected driving route are clicked in turn, the system will automatically generate line segments between these points, and connect to form a driving path. On the control panel 703, there is a special destination setting area, and the target position is directly selected on the control panel 703.

[0047] Step 103, when the AGV drives to the specified unloading site, the PLC controller drives the tipping cylinder 301 to start, the telescopic rod of the tipping cylinder 301 drives the tipping hopper 31 to rotate to stably unload the materials; after the materials are unloaded, the tipping cylinder 301 is reversely contracted to make the tipping hopper 31 return to the initial horizontal state.

[0048] Step 104, the AGV returns to the starting position or goes to the next task site according to the preset path according to the PLC controller.

[0049] Effects of the embodiment

[0050] Before starting the AGV, the operator first sets the driving path, destination and tipping unloading instruction of the AGV through the control panel 703, and other running parameters, which are transmitted to the PLC controller for storage. At the same time, the battery 802 supplies power to the electric control cabinet 705 through the power distribution circuit, and prepares for the operation of the AGV.

[0051] After the AGV starts, navigation radar 702 begins acquiring real-time location information and continuously feeds this information back to the PLC controller. Based on the preset path and current location, the PLC controller calculates the AGV's direction and speed adjustment instructions. These instructions are then sent to the first and second omnidirectional steering wheels 201 and 202 via the power distribution circuitry within the electrical control cabinet 705, controlling the AGV's travel along the preset path.

[0052] During driving, the obstacle avoidance radar 701 continuously scans the AGV's surroundings. Upon detecting an obstacle, it immediately sends an obstacle signal to the PLC controller. The PLC controller rapidly analyzes and processes the signal, generating corresponding obstacle avoidance control instructions based on the obstacle's location and distance, as well as the AGV's current driving state. The instructions are then transmitted to the first and second omnidirectional steering wheels 201 and 202 via the electrical control cabinet 705, allowing the AGV to safely avoid the obstacle and resume normal driving.

[0053] When the AGV reaches the designated unloading location, the PLC controller sends a start signal to the tipping cylinder 301 via the electrical control cabinet 705 according to the preset unloading instructions. Upon receiving the signal, the tipping cylinder 301 extends its telescopic rod, rotating the tipping hopper 31 and smoothly unloading the material. After unloading, the PLC controller sends a reverse retraction signal, causing the tipping hopper 31 to return to its initial horizontal position under its own weight.

[0054] Through pure electric drive, intelligent navigation and control of the PLC controller, the automation and intelligence of material handling are realized, which greatly improves the handling efficiency. The combined effect of the seesaw component 5, the first omnidirectional steering wheel 201 and the second omnidirectional steering wheel 202 enables the AGV to turn at multiple angles, adapt to various complex environments, and improve the flexibility of operation. The setting of the obstacle avoidance radar 701, the edge collision prevention strip 602 and the emergency stop switch 704, together, ensures the safety of the AGV during operation. The structure of the seesaw component 5 effectively balances the height difference of the ground, reduces vibration and shock, and ensures the smooth operation of the AGV in different ground environments. The PLC controller can receive the task instructions sent by the host computer in real time, and automatically plan the optimal path according to the current status, realizing efficient and accurate material handling and intelligent scheduling.

Obviously, the specific implementation of the present invention is not limited to the above-described method. Any non-substantial improvements made using the method concepts and technical solutions of the present invention, or any direct application of the above-described concepts and technical solutions to other situations without modification, fall within the scope of protection of the present invention.
