Description

Technical Field

[0001] This invention relates to the field of AGV conveying technology, specifically an AGV conveying device and method. Background Technology

[0002] With the rapid development of intelligent manufacturing and automated logistics, Automated Guided Vehicles (AGVs), as core equipment for material handling, have been widely used in warehousing, production lines, ports, and other locations. AGVs can automatically travel along preset paths, realizing automated material handling and significantly improving logistics efficiency. However, existing AGV conveying devices still have the following shortcomings in practical applications:

[0003] Poor adaptability: Different materials have different dimensions and specifications. The width of the conveying mechanism of traditional AGVs is mostly fixed or has a limited adjustment range, making it difficult to adapt to the conveying needs of various materials. When the width of the material changes, the conveying device needs to be replaced or adjusted, affecting the operating efficiency.

[0004] Limited functionality: Most existing AGVs only have material handling capabilities and lack the ability to lift and convey materials. Materials need to be adjusted in height or conveyed horizontally with the help of external equipment (such as elevators and conveyor belts), resulting in low equipment integration and large space occupation.

[0005] Insufficient conveying stability: During the conveying process, materials are prone to deviation or slippage, especially when lifting or changing direction, due to the lack of effective guiding and positioning mechanisms.

[0006] Inconvenient unloading: After the AGV arrives at its destination, the unloading of materials mostly relies on manual labor or external equipment, making it difficult to achieve automated and precise unloading and stacking.

[0007] Poor coordination between walking and conveying: There is a lack of effective coordination control between the walking mechanism and the material conveying mechanism of the AGV, making it difficult to achieve synchronous operation of walking and conveying.

[0008] Difficulty in placing multi-layer materials: For materials that need to be stacked in multiple layers, existing devices lack a mechanism to adjust the tilt angle of the placement surface, making it difficult to achieve orderly automatic stacking.

[0009] Therefore, there is an urgent need for an AGV conveying device that can adapt to the width of materials, has lifting and conveying functions, and can realize automatic unloading and stacking. Summary of the Invention

[0010] This invention provides an AGV conveying device and method, which solves the problems mentioned in the background art.

[0011] To achieve the above objectives, the present invention provides the following technical solution:

[0012] An AGV conveying device includes a mounting base. The bottom of the mounting base has several first traveling parts, and a line guide head is located at the center of the bottom of the mounting base. The mounting base has a width adjustment mechanism connected to two symmetrically arranged mounting frames, which are slidably connected to the mounting base. The bottom of each mounting frame has a second traveling part.

[0017] As a preferred embodiment of the present invention, the conveying mechanism includes two fixed plates, the distance between the two fixed plates being the same as the distance between the two lower sprockets. A mounting rod is fixedly connected to each fixed plate, the diameter of which is the same as the inner diameter of the mounting sleeve. The fixed plates are rotatably connected to a conveying shaft. Spiral auger blades are fixedly connected to the outer side of the conveying shaft, the surface of which is coated with flexible rubber. An elastic clamping mechanism is fixedly connected to the end of the conveying shaft. A conical wheel is fixedly connected to the end of the elastic clamping mechanism away from the conveying shaft. The elastic clamping mechanism includes an elastic sleeve fixedly connected to the conveying shaft, an elastic element fixedly connected inside the elastic sleeve, a rectangular slider fixedly connected to the end of the elastic element, a slidably connected rectangular slider and elastic sleeve, a pressing rod fixedly connected to the rectangular slider, the pressing rod passing through the elastic sleeve, the pressing rod and elastic sleeve being slidably connected, and the pressing rod and conical wheel being fixedly connected.

[0018] As a preferred embodiment of the present invention, the positioning drive mechanism includes a positioning frame that is slidably connected to the mounting frame, the positioning frame being threadedly connected to a second locking bolt, the end of the second locking bolt being in contact with the positioning frame, the positioning frame being fixedly connected to a motor base, a third motor being provided on the motor base, and the output shaft of the third motor being fixedly connected to a drive wheel.

[0019] As a preferred embodiment of the present invention, the placement plate mechanism includes a telescopic motor base fixed to the mounting base, a first electric telescopic rod fixedly connected to the telescopic motor base, a sliding seat fixedly connected to the end of the first electric telescopic rod away from the telescopic motor base, the sliding seat and the mounting base being slidably connected, a side plate fixedly connected to the sliding seat, and a plurality of first deflection shafts arranged vertically at equal intervals on the side plate.

[0021] A conveying method of an AGV conveying device includes the following steps:

[0022] Step 1: First, depending on the width of the conveyed material, activate the width adjustment mechanism to adjust the distance between the two mounting frames, thereby adjusting the distance between the conveying mechanisms on both sides.

[0023] Step 2: The guide head can drive the entire device to move along the line;

[0024] Step 3: As the material moves to the designated position, when it is placed on the conveyor, if it is necessary to lift the material, the drive shaft mechanism is activated. The drive shaft mechanism drives the transmission mechanism, which in turn drives the conveyor chain mechanism to work, thereby driving the conveyor to circulate and lift the material.

[0025] Step 4: When the material is lifted to the specified height, the conveying mechanism and the positioning drive mechanism come into contact. The positioning drive mechanism is then activated, which drives the conveying mechanism. The conveying mechanism moves the material toward the placement plate mechanism. In conjunction with the tilt adjustment mechanism, the material falls onto the placement plate mechanism, thus achieving the storage and placement of the material.

[0026] The present invention has the following advantages:

[0027] 1. Width self-adjustment, strong adaptability: The width adjustment mechanism is driven by a first motor to rotate the adjustment shaft. The adjustment shaft has two symmetrically arranged threaded grooves that are threadedly connected to two mounting frames. When the adjustment shaft rotates, the two mounting frames move synchronously towards or away from each other, precisely adjusting the distance between the two conveying mechanisms to adapt to materials of different widths. No parts need to be replaced, and the changeover is quick.

[0028] 2. Integrated Walking and Conveying Functions: The guide head enables the AGV to automatically walk along a preset route; the drive shaft mechanism drives the drive shaft to rotate via a second motor, which in turn drives the conveying mechanism to circulate through the transmission mechanism and conveyor chain mechanism, achieving vertical lifting of materials. The walking and conveying functions are integrated into one unit, reducing the types of equipment and the required floor space.

[0029] 3. Stable material lifting and reliable conveying: The conveyor chain mechanism adopts a double-chain structure. The conveyor mechanism is fixed to the mounting sleeve on the chain and moves cyclically with the chain. The surface of the auger blades on the conveyor mechanism is coated with flexible rubber material, which provides stable friction when in contact with the material and prevents the material from slipping. The elastic clamping mechanism keeps the conical wheel in elastic contact with the drive wheel of the positioning drive mechanism, ensuring reliable power transmission.

[0030] 4. Precise horizontal conveying and automatic unloading: When the conveying mechanism is raised to the designated height, the conical wheel on the conveying mechanism contacts the drive wheel of the positioning drive mechanism. The positioning drive mechanism drives the drive wheel to rotate through the third motor, which in turn drives the conveying shaft and the auger blades to rotate via the conical wheel and the elastic clamping mechanism, smoothly conveying the material to the placement plate mechanism, achieving automatic unloading without manual intervention.

[0031] 5. Multi-layer stacking with adjustable tilt angle: The placement plate mechanism is driven by the sliding seat to move through the first electric telescopic rod. Multiple rotatable placement plates are provided on the side plate. The second electric telescopic rod drives the bottom placement plate to deflect through the deflection seat, which drives all placement plates to move in conjunction with the fixed rod, so as to realize the synchronous adjustment of the tilt angle of the placement plates, which is convenient for the orderly stacking and storage of materials.

[0032] 6. Modular design, easy maintenance: The conveying mechanism is installed by inserting a mounting rod into the mounting sleeve on the chain and securing it with the first locking bolt, making installation and disassembly convenient. The positioning frame of the positioning drive mechanism can slide and adjust its position on the mounting frame and is locked with the second locking bolt, facilitating adjustment of the contact position between the drive wheel and the conical wheel.

[0033] 7. Stable movement and precise positioning: The first traveling unit is located at the bottom of the mounting base, and the second traveling unit is located at the bottom of the mounting frame. Multiple support points ensure stable movement of the AGV. The guide head can use magnetic navigation, laser navigation, or visual navigation to achieve precise path tracking and positioning.

[0045] Specifically, the bottom of the mounting base 1 is provided with several first traveling parts 2 for supporting and driving the AGV movement.

The adjustment shaft 402 is rotatably connected to the mounting base 1. The adjustment shaft 402 is provided with two symmetrically arranged threaded grooves 403. The mounting frame 5 is threadedly connected to the adjustment shaft 402.

[0047] Specifically, when the first motor 401 drives the adjusting shaft 402 to rotate, the two mounting frames 5 move synchronously towards or away from each other along the axial direction of the adjusting shaft 402, thereby achieving precise adjustment of the conveying width.

[0048] The drive shaft mechanism 7 includes a second motor 701 mounted on the mounting base 1. The output shaft of the second motor 701 is fixedly connected to the drive shaft 702. The drive shaft 702 and the mounting base 1 are rotatably connected. The drive shaft 702 has a drive groove 703 on its axis and passes through the mounting frame 5.

The synchronous belt 806 is driven by a second synchronous pulley 807. The conveying chain mechanism 9 includes a second rotating shaft 901 rotatably connected to the mounting frame 5. The second rotating shaft 901 and the second synchronous pulley 807 are coaxially and fixedly connected. The second rotating shaft 901 is coaxially and fixedly connected to two lower sprockets 902. The lower sprockets 902 are connected to a chain 903. The chain 903 is connected to an upper sprocket 904. The upper sprocket 904 is coaxially and fixedly connected to a third rotating shaft 905. The third rotating shaft 905 is rotatably connected to the mounting frame 5. The chain 903 is provided with a plurality of equally spaced mounting sleeves 906. The mounting sleeves 906 are threadedly connected to a first locking bolt 907.

[0049] Specifically, the rotating sleeve 801 can move axially along the drive shaft 702 with the mounting frame 5. At the same time, when the drive shaft 702 rotates, the rotating sleeve 801 rotates along with the drive groove 703 through the cooperation of the drive bar. The rotation of the rotating sleeve 801 drives the first bevel gear 802, the first bevel gear 802 drives the second bevel gear 803 to rotate, the second bevel gear 803 drives the first rotating shaft 804 to rotate, the rotation of the first rotating shaft 804 drives the second rotating shaft 901 to rotate, thereby driving the lower sprocket 902 to rotate, and then driving the chain 903 to rotate.

The rectangular slider 10053 and the elastic sleeve 10051 are slidably connected. The rectangular slider 10053 is fixedly connected to a pressing slide rod 10054. The pressing slide rod 10054 passes through the elastic sleeve 10051 and is slidably connected to the elastic sleeve 10051. The pressing slide rod 10054 and the conical wheel 1006 are fixedly connected. The positioning drive mechanism 11 includes a positioning frame 1101 that is slidably connected to the mounting frame 5.

The positioning frame 1101 is fixedly connected to a motor base 1103. A third motor 1104 is provided on the motor base 1103. The output shaft of the third motor 1104 is fixedly connected to a drive wheel 1105.

[0051] Specifically, the elastic element 10052 provides continuous elastic force, keeping the conical wheel 1006 in elastic contact with the drive wheel of the positioning drive mechanism 11, ensuring reliable power transmission. When the conveying mechanism 10 is lifted to a specified height by the chain 903, the conical wheel 1006 contacts the drive wheel 1105. The drive wheel 1105 rotates, causing the conical wheel 1006 to rotate. This rotation is transmitted to the conveying shaft 1003 via the elastic clamping mechanism 1005, causing the auger blades 1004 to rotate and push the material toward the placement plate mechanism 12.

[0052] The placement plate mechanism 12 includes a telescopic motor base 1201 fixed on the mounting base 1. The telescopic motor base 1201 is fixedly connected to a first electric telescopic rod 1202.

[0053] Specifically, when the second electric telescopic rod 1302 extends or retracts, it drives the bottom placement plate 1206 to deflect around the first deflection shaft 1205. Through the fixed rod 1208, it drives all placement plates 1206 to deflect synchronously, adjusting the tilt angle of the placement surface to facilitate material sliding or stacking.

[0054] Example 2, see below. Figures 1-7 In an embodiment of the present invention, a conveying method of an AGV conveying device includes the following steps:

[0055] Step 1: First, depending on the width of the conveyed material, the width adjustment mechanism 4 is activated to adjust the distance between the two mounting frames 5, thereby adjusting the distance between the conveying mechanisms 10 on both sides.

[0056] Step 2: The guide head 3 can drive the entire device to move along the line;

[0057] Step 3: As the material is moved to the designated position and placed on the conveyor mechanism 10, if it is necessary to lift the material, the drive shaft mechanism 7 is activated. The drive shaft mechanism 7 will drive the transmission mechanism 8, which will drive the conveyor chain mechanism 9 to work, thereby driving the conveyor mechanism 10 to circulate and thus lifting the material.

[0058] Step 4: When the material is lifted to the specified height, the conveying mechanism 10 contacts the positioning drive mechanism 11. The positioning drive mechanism 11 is then activated, which drives the conveying mechanism 10. The conveying mechanism 10 moves the material toward the placement plate mechanism 12. With the help of the tilt adjustment mechanism 13, the material falls onto the placement plate mechanism 12, thus achieving the storage and placement of the material through the placement plate mechanism 12.

[0059] The following is the workflow of this invention:

[0060] Width adjustment: Based on the width of the material to be conveyed, start the first motor 401 to drive the adjustment shaft 402 to rotate, and the two mounting frames 5 move synchronously towards or away from each other so that the distance between the two conveying mechanisms 10 is matched with the width of the material.

[0061] AGV movement: The guide head 3 detects the navigation line and controls the first walking unit 2 and the second walking unit 6 to drive the AGV to move along the designated path to the material picking point.

[0062] Material loading: Place the material on the auger blades 1004 of the conveying mechanism 10.

[0063] Vertical lifting: Start the second motor 701 to drive the drive shaft 702 to rotate, which drives the conveyor chain mechanism 9 to operate through the transmission mechanism 8. The chain 903 drives the conveyor mechanism 10 to move upward in a circular motion, lifting the material to the specified height.

[0064] Horizontal conveying: When the conveying mechanism 10 is raised to the height of the positioning drive mechanism 11, the conical wheel 1006 contacts the drive wheel 1105. The third motor 1104 is started, and the drive wheel 1105 rotates, driving the conical wheel 1006 to rotate, causing the auger blades 1004 to rotate, and conveying the material horizontally towards the placement plate mechanism 12.

[0065] Unloading and Stacking: Materials are conveyed onto the placement plate 1206. Based on stacking requirements, the second electric telescopic rod 1302 is activated to adjust the tilt angle of the placement plate 1206, ensuring the materials are arranged in an orderly manner. The first electric telescopic rod 1202 can drive the sliding seat 1203 to move, adjusting the receiving position of the placement plate mechanism 12.

[0066] Cyclic operation: The conveying mechanism 10 continues to cycle with the chain 903, repeating the above steps to achieve continuous conveying.

[0067] Through the above design, this invention realizes the adaptive width adjustment of AGV, vertical lifting of materials, horizontal conveying, and automatic unloading and stacking, which significantly improves the material conveying capacity and operating efficiency of AGV.

[0068] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
