Description

Technical Field

[0001] This application relates to the field of unmanned transport vehicle technology, and in particular to an unmanned transport vehicle for intelligent warehousing. Background Technology

[0002] With the rapid development of intelligent manufacturing and e-commerce, higher demands are being placed on the efficiency, accuracy, and flexibility of warehousing and logistics systems. Currently, material handling systems based on Automated Guided Vehicles (AGVs) are widely used.

[0003] Existing unmanned transport vehicles (UGVs) cannot adjust the spacing of their side forks when transporting goods, and their length is fixed. This prevents them from being adjusted according to the size of the pallet and the spacing of the bottom slots. Furthermore, while they rely entirely on sensors to avoid obstacles during autonomous driving, they cannot detect falling items. Over time, the sensor surfaces are prone to accumulating debris, leading to a decrease in sensing accuracy. Consequently, the safety and efficiency of the transport vehicle are reduced. To address these issues, we propose an intelligent unmanned transport vehicle for warehousing. Summary of the Invention

The fixed plate 61 is provided with two second sliding holes 12 and one first sliding hole 11 at equal intervals. The bottom of the moving plate 62 is fixedly installed with a linear motor 10, and the position of the moving seat in the linear motor 10 corresponds to the position of the first sliding hole 11. The sliding blocks 17 are slidably connected to the inside of the first sliding hole 11 and the second sliding hole 12 respectively, and one of the sliding blocks 17 is fixedly connected to the moving seat in the linear motor 10.When picking up an item dropped on the ground, the linear motor 10 is activated, causing the moving plate 62 to move to the left, facilitating the movement of the item onto the wedge-shaped support block 18. A second mounting cavity 15 is located inside the lower end of the buffer plate 67. The upper end of the push plate 66 is slidably connected to the interior of the second mounting cavity 15. Multiple second tension springs 16 are fixedly installed at equal intervals between the push plate 66 and the upper sidewall of the second mounting cavity 15. When the push plate 66 moves on the wedge-shaped support block 18, the inclined surface of the wedge-shaped support block 18 causes the push plate 66 to move towards the interior of the second mounting cavity 15 in the connecting plate 68, effectively moving the dropped item above the wedge-shaped support block 18. The upper sidewall of the buffer plate 67 is connected to the fixed plate 61. The bottom of the buffer plate 67 and the lower side wall of the connecting plate 68 are both provided with T-shaped grooves 26.

The second camera 14 and radar 20 on the unmanned transport vehicle can sense the movement of the unmanned transport vehicle. Since there are staff members at the back of the unmanned transport vehicle 1 to check, the push plate 66 can be used to move the goods that have fallen on the ground to the wedge-shaped support block 18 according to the movement of the unmanned transport vehicle.

[0029] As a further preferred embodiment, according to as follows Figure 1 and Figure 2 As shown, the adjustment mechanism 5 includes a moving block 51. A moving groove 55 is provided inside the right end of the support base 2. A bidirectional screw 52 is rotatably connected between the two side walls of the moving groove 55. The left ends of the first support column 4 are slidably connected inside the moving groove 55 and threaded onto the outside of the bidirectional screw 52. A reciprocating motor 54 is fixedly installed at the front end of the support base 2. The output shaft of the reciprocating motor 54 passes through the side wall of the support base 2 and is fixedly connected to the front end of the bidirectional screw 52. Moving holes 53 are provided inside the upper and lower side walls of the moving groove 55. Moving blocks 51 are fixedly installed on the upper and lower side walls of the left side of the first support column 4 and slidably connected inside the moving holes 53. The position of the first support column 4 can be adjusted according to the distance between the gaps on both sides of the bottom of the support tray where the goods are placed. By rotating the bidirectional screw 52, ​​the spacing of the first support column 4 can be effectively adjusted. Simultaneously, under the limiting action of the moving block 51, the position of the first support column 4 can be stabilized during movement.

[0030] As a further preferred embodiment, according to as follows Figure 1 , Figure 2 , Figure 3, Figure 4 and Figure 5 As shown, the extension mechanism 7 includes a fixed column 74. The right end of the first support column 4 is provided with a support groove 75. The left end of the fixed column 74 is fixedly connected to the left side wall of the support groove 75.

The bottom of the second support column 13 and the first support column 4 are respectively fixedly installed with a second fixing block 72 and a first fixing block 71. An adjusting cylinder 73 is fixedly installed on the left side wall of the first fixing block 71. The output shaft of the adjusting cylinder 73 is fixedly connected to the left side wall of the second fixing block 72 through the inside of the first fixing block 71. The position of the second support column 13 can be adjusted according to the size of the items to be transported. Opening the adjusting cylinder 73 pushes the second fixing block 72, which allows the position of the second support column 13 to be moved conveniently.

[0031] As a further preferred embodiment, according to as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the limiting mechanism 8 includes a limiting plate 81. A first mounting cavity 83 is provided inside the right end of each of the second support columns 13. The limiting plate 81 is slidably connected to the inside of the right end of each of the second support columns 13, and its lower end is slidably connected to the inside of the first mounting cavity 83. Multiple first tension springs 82 are fixedly installed at equal intervals between the bottom of the limiting plate 81 and the bottom of the first mounting cavity 83. Fixed rods 84 are fixedly installed at equal intervals at the bottom of the first mounting cavity 83. The first tension springs 82 are respectively sleeved on the outside of the fixed rods 84, and the lower end of the limiting plate 81 is slidably sleeved on the outside of the fixed rods 84. When supporting an item, under the action of the first tension springs 82, the upper end of the limiting plate 81 moves to the upper end of the second support column 13, and its bottom extends to support the upper end of the first support column 13, effectively enabling the detection of placed goods.

[0032] The working principle of this invention is as follows: During transport of goods in a warehouse, the unmanned transport vehicle 1 is first moved to one side of the goods. The spacing of the first support columns 4 on both sides is adjusted according to the spacing within the cargo chassis. Simultaneously, the position of the second support column 13 is adjusted according to the length of the goods. The adjusting cylinder 73 is activated, and its output shaft pushes the second fixing block 72, causing the second support column 13 to slide along the fixing column 74 within the support groove 75. This adjusts the total support length of the first and second support columns 4 to accommodate goods of different lengths. Then, the reciprocating motor 54 in the adjusting mechanism 5 drives the bidirectional screw 52 to rotate, thereby... The first support columns 4 on both sides move closer or further apart along the moving block 51 inside the moving hole 53. After adjusting the spacing to match the slot of the cargo chassis, the unmanned transport vehicle 1 is controlled to move the first support columns 4 into the slot of the cargo chassis to complete the retrieval of goods. During transportation, when the limiting plate 81 contacts the goods, under the action of the weight of the goods, the limiting plate 81 compresses the first tension spring 82 and moves downward. With the help of the internal sensor, it can sense whether the goods are placed in place. At the same time, the limiting plate can also limit the side of the goods to prevent the goods from slipping during transportation. If small items are detected to have fallen on the ground during transportation, the unmanned transport vehicle 1 is moved to the side of the fallen items so that the fallen items are positioned within the first support columns. In the meantime, the linear motor 10 is turned on, driving the slider to move along the sliding hole, pushing the moving plate 62 to extend towards the direction of the falling goods. Then, the push cylinder 691 is turned on, pushing the buffer plate 67 to move downward along the connecting plate, so that the push plate 66 pushes the falling goods along the inclined surface of the wedge-shaped support block 18. At the same time, when the goods fall, the second camera 14 and radar 20 on the unmanned transport vehicle can detect it during the movement of the unmanned transport vehicle. And since there are staff at the back of the unmanned transport vehicle 1 to monitor it, they can use the push plate 66 to move the fallen goods to the wedge-shaped support block 18 according to the movement of the unmanned transport vehicle. During the process, the push plate 66 compresses the second The tension spring moves adaptively inside the second mounting cavity to ensure that the push plate always fits the goods, eventually lifting the fallen goods above the wedge-shaped support block for retrieval. This prevents the fallen goods from obstructing the passage of the unmanned transport vehicle. When dust and dirt adhere to the surface of the radar 20 and camera components at the front of the device, affecting the sensing accuracy, the electric slider 93 in the cleaning mechanism 9 is activated to move along the guide rail 91, causing the cleaning cotton 97 on the surface of the mounting block 96 to move and wipe the radar and camera surfaces. At the same time, the water tank 92 delivers cleaning water to the cleaning cotton 97 through the water pipe 95, improving the cleaning effect and rinsing away the debris attached to the surface of the cleaning cotton, ensuring the cleaning ability of the cleaning cotton and maintaining the detection accuracy of the sensing components.
