Description

Technical Field

[0001] This invention relates to the field of AGV (Automated Guided Vehicle) transport equipment technology, specifically to an AGV transport vehicle for logistics warehousing and its usage method. Background Technology

[0002] AGV (Automated Guided Vehicle) transport vehicles for logistics and warehousing are one of the core equipment in the warehouse automation system. Their core function is to replace manual labor in material handling through automation and intelligent means. The most basic function of the AGV transport vehicles is to meet the core needs of "material displacement" in warehousing, covering the entire chain of handling scenarios from inbound to outbound, thereby completely reducing the dependence on manual labor and improving handling efficiency.

[0003] For example, the invention patent disclosed in publication number CN117507996A discloses an AGV (Automated Guided Vehicle) unmanned transport vehicle, which includes a transport vehicle body and a support plate. A first storage groove is opened in the middle of the upper part of the transport vehicle body. A hydraulic cylinder is installed in the middle of the front and rear sides of the lower inner wall of the first storage groove. The top of the output shaft of the hydraulic cylinder is connected to the support plate. Guide rods are connected to the four corners of the lower part of the support plate. By sliding the U-shaped rod in the first guide groove, the first rotating rod is driven to rotate through the rack and the first gear, thereby rotating the extension plate to a horizontal state. The two extension plates can increase the support area of ​​the transport vehicle body for objects, reduce the problem of objects falling during the transport process, and improve the transport efficiency. When the hydraulic cylinder drives the support plate to move downward, the extension plates can be automatically retracted on both sides of the support plate, and the support plate and the extension plate are stored in the first storage, reducing space occupation and facilitating storage.

[0004] Although the aforementioned AGV clamping equipment can clamp materials, its stability and adaptability in limiting the transported materials are insufficient. At the same time, the all-terrain transport performance of the aforementioned AGV transport vehicle is also insufficient. Therefore, there is a need for an AGV transport vehicle for logistics warehousing and its usage method to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide an AGV (Automated Guided Vehicle) for logistics warehousing and its usage method, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an AGV transport vehicle for logistics warehousing, comprising an AGV seat for support, four sets of drive motors equidistantly arranged on the inner end face of the AGV seat, and a support hub provided at the output end of each set of drive motors, and ohmic wheels equidistantly arranged on the outer end face of the support hub. A guiding device is fixedly installed on the upper surface of the AGV seat, and the guiding device is used for positioning and guiding. The clamping device comprises four sets, all of which are slidably engaged with the inner end face of the guide device. The clamping device is used for support and limiting.

[0007] Preferably, the clamping device includes a guide slide, a motor clamping plate is fixedly provided on the rear end face of the guide slide, and a guide slide shaft is provided on the lower end face of the guide slide. A servo motor is fixedly provided at the center of the upper end face of the motor clamping plate, and a transmission screw is provided at the output end of the servo motor. A threaded slide is threadedly connected to the inner end face of the guide slide, and an alignment pressure plate is provided on the side end face of the threaded slide.

[0008] Preferably, the guiding device includes a support bracket, a motor guide seat is provided at the center of the side end face of the support bracket, an alignment guide seat is provided at the center of the lower end face of the support bracket, and a driven gear is rotatably engaged on the inner end face of the support bracket. Four sets of guide grooves are equidistantly provided on the inner end face of the driven gear extending to the bottom. A reduction motor is provided near the bottom of the side end face of the support bracket, a drive gear is provided at the output end of the reduction motor, and four sets of linear grooves are equidistantly provided on the upper end face of the support bracket.

[0009] Preferably, the driving gear and the driven gear are meshed together, which can effectively improve the stability of subsequent transmission.

[0010] Preferably, the guide slide is adapted to the guide shaft through the guide groove and then slidably engages with the support bracket inside. The guide groove can be arc-shaped or inclined, which can facilitate the provision of sufficient centripetal guidance for the guide shaft during subsequent rotation, thereby improving the stability and adaptability of the guide slide for limiting materials of different sizes.

[0011] Preferably, the guide slide is slidably engaged with the linear groove, and the linear groove provides sufficient linear guiding foundation for the guide slide, thereby improving the stability of the subsequent displacement of the guide slide within the support bracket.

[0012] Preferably, the alignment plate is adapted to the transmission screw through the threaded slide and is threadedly connected inside the guide slide. The alignment plate is made of rubber and has a certain degree of flexible deformation, which can prevent rigid damage to the material when the threaded slide moves down.

[0013] A method for using an AGV (Automated Guided Vehicle) for logistics warehousing includes the following steps: S1: Pre-loading: The goods or materials to be transported can be positioned on the upper part of the support base by the external material guiding module to complete the pre-loading operation; S2: Limiting the side of the material, the reduction motor can drive the driven gear to mesh and rotate through the drive gear, the driven gear can drive the four sets of guide slides to rotate, the guide slides can slide and limit with the guide slide shaft, and then synchronously drive the four sets of guide slides to move centripetally, so that the four sets of guide slides can lock and limit the side of the material on the upper part of the support card seat in the center. S3: The upper part of the material is pressed and limited. The servo motor can drive the transmission screw to rotate. The transmission screw can drive the alignment pressure plate to move down through the threaded connection with the threaded slide, so that the four sets of alignment pressure plates can lock and limit the upper part of the material. S4: All-around handling and conveying. Four sets of drive motors can independently control the speed of four sets of support hubs and ohmic wheels. By using the speed difference between different sets of ohmic wheels and support hubs, the AGV can achieve all-around steering and displacement.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting up a guiding device, when adaptively limiting the material to be transported, the reduction motor can drive the guide slide to rotate synchronously through the meshing of the driving gear and the driven gear. This allows the four sets of guide slides to be limited by sliding with the guide slide shaft, thereby synchronously driving the four sets of guide slide blocks to centripetally limit the material. This facilitates the stability of locking and limiting materials of different sizes, thereby improving the practical performance of the AGV transport vehicle.

[0015] 2. By setting up a clamping device, when locking the upper part of the material, the servo motor can be connected to the threaded slide through the transmission screw, thereby driving the alignment plate to move down inside the guide slide. This allows the alignment plate to lock and limit the upper part of the material, effectively improving the stability of the equipment in limiting the material, and thus improving the efficiency of the AGV trolley in transporting the material.

[0016] 3. During transportation, each set of ohmic wheels and support hubs is individually controlled by a set of drive motors, which can quickly and accurately adjust the AGV vehicle by means of speed difference. In addition, the diameter of the ohmic wheels and support hubs is relatively high, which can effectively improve the overall passability of the vehicle and thus improve the stability of the AGV vehicle when running in all terrains.

Guide device 3 is fixedly installed on the upper surface of AGV seat 6. Guide device 3 is used for positioning and guiding. The clamping device 2 has four sets, and all four sets of clamping devices 2 are slidably engaged with the inner end face of the guide device 3.

[0024] The clamping device 2 includes a guide slide 21, a motor clamping plate 22 is fixedly provided on the rear end face of the guide slide 21, and a guide slide shaft 23 is provided on the lower end face of the guide slide 21. A servo motor 27 is fixedly provided at the center of the upper end face of the motor clamping plate 22, and a transmission screw 24 is provided at the output end of the servo motor 27. A threaded slide 26 is threadedly connected to the inner end face of the guide slide 21, and an alignment pressure plate 25 is provided on the side end face of the threaded slide 26.

[0025] The guide device 3 includes a support bracket 37. A motor guide seat 31 is provided at the center of the side end face of the support bracket 37. An alignment guide seat 34 is provided at the center of the lower end face of the support bracket 37. A driven gear 36 is rotatably engaged on the inner end face of the support bracket 37. Four sets of guide grooves 35 are equidistantly provided on the inner end face of the driven gear 36 extending to the bottom. A reduction motor 33 is provided near the bottom of the side end face of the support bracket 37. A drive gear 32 is provided at the output end of the reduction motor 33. Four sets of linear grooves 38 are equidistantly provided on the upper end face of the support bracket 37.

[0026] The driving gear 32 meshes with the driven gear 36, which can effectively improve the stability of subsequent transmission.

[0027] The guide slide 21 is adapted to the guide slide shaft 23 through the guide slide groove 35 and then slides and engages in the support seat 37. The guide slide groove 35 can be arc-shaped or inclined, which can provide sufficient centripetal guidance for the guide slide shaft 23 when rotating, and improve the stability and adaptability of the guide slide 21 to limit materials of different sizes.

[0028] The guide slide 21 is slidably engaged with the linear slide groove 38. The linear slide groove 38 can provide sufficient linear guiding foundation for the guide slide 21, thereby improving the stability of the subsequent displacement of the guide slide 21 inside the support bracket 37.

[0029] The alignment plate 25 is adapted to the transmission screw 24 through the threaded slide 26 and is threadedly connected inside the guide slide 21. The alignment plate 25 is made of rubber and has a certain degree of flexible deformation, which can prevent the subsequent threaded slide 26 from causing rigid damage to the material when it moves down.

[0030] A method for using an AGV (Automated Guided Vehicle) for logistics warehousing includes the following steps: S1: Pre-loading: The goods or materials to be transported can be positioned on the upper part of the support bracket 37 by the external material guiding module to complete the pre-loading operation. S2: To limit the material on the side, the reduction motor 33 can drive the driven gear 36 to rotate through the drive gear 32. The driven gear 36 can drive the four sets of guide slides 35 to rotate. The guide slides 35 can be limited by sliding with the guide slide shaft 23, and then synchronously drive the four sets of guide slides 21 to perform centripetal displacement, so that the four sets of guide slides 21 can lock and limit the material on the side of the support bracket 37 in the center. S3: Press and limit the upper part of the material. The servo motor 27 can drive the transmission screw 24 to rotate. The transmission screw 24 can drive the alignment plate 25 to move down through the threaded connection with the threaded slide 26, so that the four sets of alignment plates 25 can lock and limit the upper part of the material. S4: All-around handling and conveying. Four sets of drive motors 1 can independently control the speed of four sets of support hubs 5 and ohmic wheels 4. By using the speed difference between different sets of ohmic wheels 4 and support hubs 5, the AGV can achieve all-around steering and displacement.

[0031] Working principle: Before use, the operator can position the goods or materials to be transported onto the upper part of the support bracket 37 using the external material guiding module. When positioning the materials or goods, the reduction motor 33 starts. At this time, the reduction motor 33 can drive the driven gear 36 to mesh and rotate through the drive gear 32. The driven gear 36 can drive the four sets of arc-shaped guide slides 35 to rotate. The guide slides 35 can be limited by sliding with the guide slide shaft 23, thereby synchronously driving the four sets of guide slides 21 to perform centripetal displacement, so that the four sets of guide slides 21 can move towards the support bracket 37. The upper material is centered and locked on the side. After the locking is completed, four servo motors 27 can be started simultaneously. At this time, the servo motors 27 can drive the transmission screw 24 to rotate. The transmission screw 24 can drive the alignment plate 25 to move down through the threaded connection with the threaded slide 26, so that the four alignment plates 25 can lock and limit the upper part of the material. When the material is transported, the four drive motors 1 can independently control the speed of the four support hubs 5 and ohmic wheels 4. Through the speed difference of different sets of ohmic wheels 4 and support hubs 5, the AGV can achieve all-round steering and displacement.
