Description

Technical Field

[0001] This application relates to the field of AGV technology, and in particular to a dual-station integrated lifting AGV. Background Technology

[0002] With the rapid development of industrial automation and intelligent manufacturing, Automated Guided Vehicles (AGVs) are being used more and more widely in logistics and warehousing. AGVs consist of a vehicle body, drive system, guidance system, safety system, and communication system. AGVs can efficiently, accurately, and safely complete various material handling tasks.

[0003] However, traditional AGVs for shaft handling are usually designed as single-station vehicles, which limits their transportation and loading / unloading efficiency to some extent.

[0004] Therefore, it is necessary to propose a dual-station integrated lifting AGV to improve the transportation and loading / unloading efficiency of AGVs, which has become an important technical problem that needs to be solved urgently. Utility Model Content

[0005] This application provides a dual-station integrated lifting AGV, which aims to solve the problem that traditional shaft handling AGVs in the prior art are usually designed as single-station vehicles, which to some extent limits their transportation and loading / unloading efficiency.

[0006] To achieve the above objectives, this application proposes a dual-station integrated lifting AGV, including the AGV and further comprising: a lifting platform; a lifting assembly, which is mounted on the AGV and is used to lift the lifting platform; a connecting seat, which is provided at both ends of the lifting platform; and a support platform, which is provided on both sides of the connecting seat, and on which materials are placed.

[0007] In some embodiments, the system further includes a flexible element disposed on the support platform.

[0008] In some embodiments, the lifting assembly includes: a bracket disposed on the AGV; a lifting drive disposed on the bracket; a screw rotatably disposed on the bracket and connected to the lifting drive; a nut block screwed to the screw; and a lifting seat connected to the nut block and connected to a lifting platform.

[0009] In some embodiments, the system further includes: a slide rail, which is mounted on the support; and a slider that is adapted to the slide rail and connected to the lifting seat.

[0010] In some embodiments, it further includes: a protective cover disposed on the AGV, and the lifting assembly located inside the protective cover.

[0011] This application proposes a dual-station integrated lifting AGV, comprising an AGV and: a lifting platform; a lifting assembly mounted on the AGV for lifting the lifting platform; connecting seats at both ends of the lifting platform; and support platforms on both sides of the connecting seats, on which materials are placed. During loading or unloading, the height of the lifting platform can be adjusted to adapt to the height of the rack, facilitating the loading and unloading of material shafts. During transportation, the lifting platform retracts, effectively lowering the center of gravity of the dual-station integrated lifting AGV and improving its stability. The support platforms on one side of the two connecting seats form a pair of support platforms, with the two ends of the material shaft resting on the two support platforms of the same pair. The support platforms on the other side of the two connecting seats form another pair of support platforms. These two pairs of support platforms form a dual-station configuration, allowing the AGV to carry two material shafts, effectively improving the AGV's transportation and loading / unloading efficiency.

Detailed Implementation

[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0015] See Figure 1 , Figure 3 and Figure 4 As shown, this application proposes a dual-station integrated lifting AGV, including AGV1, and further including: a lifting platform 10; a lifting component, which is disposed on AGV1 and is used to lift the lifting platform 10; a connecting seat 3, which is disposed at both ends of the lifting platform 10; and a support platform 5, which is disposed on both sides of the connecting seat 3, and materials are placed on the support platform 5.

[0016] AGV1 is the main structure of the dual-station integrated lifting AGV, and all other structures on the dual-station integrated lifting AGV are directly or indirectly connected to AGV1. The lifting platform 10 and the lifting components form a lifting structure. During loading or unloading, the lifting platform 10 drives the support platform 5 to rise, making the vertical height of the support platform 5 level with or slightly lower than the shelf, facilitating the loading and unloading of the material shaft 4. During transportation, the lifting platform 10 drives the support platform 5 to descend, effectively lowering the center of gravity of the dual-station integrated lifting AGV and improving its stability.

[0017] Among them, the connecting seat 3 and the support platform 5 are the core structures of the dual-station integrated lifting AGV. It can be understood that the two ends of the lifting platform 10 are connected to the connecting seat 3 by screws. The two connecting seats 3 are integrally formed with the support platform 5. The support platform 5 on one side of the two connecting seats 3 forms a pair of support platforms 5. The two ends of the material shaft 4 are respectively placed on the two support platforms 5 of the same pair. The support platform 5 on the other side of the two connecting seats 3 forms another pair of support platforms 5. The two pairs of support platforms 5 form a dual station, which allows the AGV1 to load two material shafts 4, effectively improving the transportation and loading and unloading efficiency of the AGV1.

[0018] Specifically, during the loading or unloading process, the height of the lifting platform 10 can be adjusted to adapt to the height of the shelf, facilitating the loading and unloading of material shafts 4. During transportation, the lifting platform 10 retracts, effectively lowering the center of gravity of the dual-station integrated lifting AGV and improving its stability. The support platforms 5 on one side of the two connecting seats 3 form a pair of support platforms 5, with the two ends of the material shafts 4 resting on the two support platforms 5 of the same pair. The support platforms 5 on the other side of the two connecting seats 3 form another pair of support platforms 5. The two pairs of support platforms 5 form a dual-station configuration, allowing the AGV1 to carry two material shafts 4, effectively improving the transportation and loading / unloading efficiency of the AGV1.

[0019] The support platform 5 is provided with a V-shaped support groove, and the material shaft 4 rests on the support groove of the support platform 5.

[0020] This includes a sensor assembly mounted on AGV1 to detect the presence and positioning of materials on support platform 5. Specifically: The presence of support platform 5 is detected using a weight sensor: a weight sensor is installed on support platform 5, and when material shaft 4 is placed on support platform 5, the sensor detects a change in weight, thus determining the presence of material shaft. The positioning of material shaft is detected using a vision sensor camera, which uses image processing technology to identify the edges and position of material shaft.

[0021] Understandably, we use weight sensors and vision sensors (cameras) to achieve the above functions: When AGV1 moves to the designated position for loading and unloading operations, the weight sensor first checks whether there is a material shaft 4 on the support platform 5. If no weight change is detected, the control system knows that there is currently no material shaft 4 on the support platform 5. After loading the material shaft 4, the vision sensor camera takes a picture of the support platform 5 and analyzes the edge and position of the material shaft using an image processing algorithm. If the material shaft 4 is correctly placed in the support groove of the support platform 5, the algorithm will recognize this state and send a signal to the control system indicating that the material shaft 4 has been correctly positioned. If the material shaft 4 exists but is not accurately positioned, the control system can issue an alarm based on the feedback from the vision sensor to prompt the operator to make manual adjustments.

[0022] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, a flexible member 6 is further included, which is disposed on the support platform 5. The flexible member 6 can prevent hard contact between the material shaft 4 and the support platform 5, thereby effectively protecting the material shaft 4 and preventing the surface of the material shaft 4 from being scratched during transportation.

[0023] In this embodiment, the flexible component 6 is a rubber component. The flexible component 6 is fixed to the support groove by bonding. Both groove surfaces of the support groove are provided with the flexible component 6. The rubber material of the flexible component 6 has a large surface friction coefficient, which is beneficial for the material shaft 4 to be stably placed on the support groove.

[0024] See Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the lifting assembly includes: a bracket 7, which is mounted on the AGV1; the bracket 7 is fixed to the AGV1 by screws; a lifting drive 9, which is mounted on the bracket 7; the lifting drive 9 is a motor, and a mounting bracket 8 is connected to the bracket 7 by screws, and the motor is connected to the mounting bracket 8 by screws; a screw 15, which is rotatably mounted on the bracket 7 and connected to the lifting drive 9; the lifting drive 9 has an output shaft, which is connected to the screw 15 through a coupling 16 to drive the screw 15 to rotate; a nut block, which is screwed to the screw 15; the rotation of the screw 15 causes the nut block to move up and down; a lifting seat 14, which is connected to the nut block and to the lifting platform 10. The lifting seat 14 is detachably connected to the nut block by screws, and the lifting seat 14 is detachably connected to the lifting platform 10 by screws, and the lifting drive 9 drives the lifting platform 10 to move up and down.

[0025] See Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the system further includes: a slide rail 13, which is mounted on the bracket 7; the slide rail 13 is installed on the bracket 7 by screws; a slider 12, which is adapted to the slide rail 13 and connected to the lifting seat 14. The slider 12 is movably mounted on the slide rail 13, and is connected to an intermediate frame 11 by screws. The intermediate frame 11 is connected to the lifting seat 14 by screws. The cooperation between the slider 12 and the slide rail 13 improves the stability of the movement of the lifting seat 14, thereby improving the stability of the material shaft 4 moving up and down.

[0026] See Figure 1 As shown, in some embodiments, it further includes a protective cover 2, which is disposed on the AGV, and the lifting component is located inside the protective cover 2. The protective cover 2 is used to isolate the lifting component from the external environment, prevent the lifting component from being corroded by dust and moisture from the external environment, extend the service life of the lifting component, and also help to improve the stability of the lifting component.

All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
