Description

Technical Field

[0001] The utility model relates to the technical field of AGV equipment, in particular to an AGV trolley capable of high-precision docking. Background Art

[0002] AGV is an automatic guided vehicle, also known as an automatic guided transport vehicle or an automatic guided transport vehicle. It is equipped with an electromagnetic or optical automatic guidance device, can travel along a specified guidance path, and has safety protection and various transfer functions. When the current AGV docks with the cargo platform, it performs precise positioning and docking based on the navigation accuracy of its own system. Among them, the existing AGV car that can perform high-precision docking is as follows:

[0003] The Chinese patent document with the publication number CN215401246U discloses a correction device for high-precision docking of an AGV trolley and a transport line body, which specifically discloses: including a body, a support platform, a vehicle-mounted line body, and a vehicle-mounted control system. The correction device includes a camera and an alignment mark. The camera is installed on the support platform of the AGV trolley and is located on the vertical plane where the central axis of the vehicle-mounted line body is located. The camera is connected to and controlled by the vehicle-mounted control system of the AGV trolley. The alignment mark is installed on the transport line body and is located on the vertical plane where the central axis of the transport line body is located. The AGV trolley recognizes the alignment mark through the camera, and the vehicle-mounted control system automatically analyzes and determines the position of the transport line body, thereby controlling the movement of the AGV trolley body, ensuring that the vehicle-mounted line body and the transport line body are aligned and docked with high precision, so that the material box can be transported smoothly between the vehicle-mounted line body and the transport line body without being worn by the material box.

[0004] As can be seen from the above, when the existing AGV cart is transporting material boxes, the AGV cart automatically corrects the position through a correction device. When the camera reads the QR code on the transport line body, the on-board control system of the AGV cart will automatically analyze and determine the position of the transport line body, and then control the movement of the AGV cart. The AGV cart moves to the predetermined position, and then the high-precision docking of the on-board line body and the transport line body on the AGV cart is achieved. However, the existing AGV cart cannot adjust the horizontal position and height position of the on-board line body, so that the on-board line body and the transport line body are misaligned, thereby affecting the subsequent material transportation and processing. Therefore, an AGV cart that can perform high-precision docking is provided to solve the above technical problems. Utility Model Content

[0028] The following is a detailed description of an AGV vehicle capable of high-precision docking according to the present invention in conjunction with the accompanying drawings.

[0029] like Figure 1 As shown, an embodiment of an AGV trolley capable of high-precision docking of the utility model includes a seat 1 and a plurality of first movable wheels 2 arranged on the seat 1. The seat 1 can be driven to move by controlling the rotation of the first movable wheels 2, so as to move to a designated position for docking with a production line device (not shown in the figure); wherein, a lifting platform 3 that can move up and down and is used to support materials is provided on the seat 1. When the seat 1 moves to a designated position, the lifting platform 3 is controlled to move upward so that the lifting platform 3 is docked with the discharge position of the production line device (not shown in the figure), and the material can be transported to the lifting platform 3, which is convenient for the subsequent handling and transportation of the material. In addition, a vertically arranged guide rail 7 is provided on the seat 1, and a second slider 8 is fixedly provided on the lifting platform 3. The second slider 8 is slidably arranged on the guide rail 7. Under the action of the guide rail 7 and the second slider 8, the lifting platform 3 can be more stable when moving up and down.

[0030] Preferably, a groove 34 is provided at the bottom of the lifting platform 3, and a pair of lifting mechanisms 4 are installed on the seat 1 for controlling the lifting platform 3 to move up and down a specified distance and are placed in the groove 34. By placing the lifting mechanism 4 in the groove 34, the overall height of the AGV car is reduced, making it more stable when moving, and its small size can also improve the adaptability of the AGV car to different workshop environments; by operating the lifting mechanism 4, the lifting platform 3 is controlled to move up or down a specified distance, the accuracy of the up and down movement of the lifting platform 3 is ensured, so that the height error between the lifting platform 3 and the discharge position of the production line equipment (not shown in the figure) is within ±5mm.

[0031] In order to facilitate the transportation of materials to the lifting platform 3, a plurality of material receiving mechanisms 5 for receiving materials are installed on the top of the lifting platform 3. By controlling the rotation of the first moving wheel 2 to drive the vehicle seat 1 to move to the specified position, the vehicle seat 1 can be docked with the production line equipment (not shown in the figure), and then the jacking mechanism 4 is operated to control the lifting platform 3 to move upward a specified distance, so that the material receiving mechanism 5 is connected with the discharge position of the production line equipment (not shown in the figure). At the same time, the production line equipment and the material receiving mechanism 5 are operated to receive materials and transport the materials to the lifting platform 3, thereby completing the automatic loading process of the materials. After receiving a certain amount of materials, the jacking mechanism 4 is operated to control the lifting platform 3 to reset downward, and then the vehicle seat 1 is driven to move to transport and carry the materials.

[0032] In addition, an adjustment mechanism 6 for fine-tuning the position of the seat 1 is provided at the bottom of the seat 1. When the lifting mechanism 4 controls the lifting platform 3 to move upward a specified distance, the lifting platform 3 and the discharge position of the production line equipment (not shown in the figure) may be misaligned. To solve this problem, the position of the lifting platform 3 can be adjusted by operating the adjustment mechanism 6 to control the horizontal movement of the seat 1, and the movement direction is perpendicular to the direction in which the first moving wheel 2 drives the seat 1 to move. Then, in cooperation with the lifting mechanism 4, the receiving mechanism 5 is connected to the discharge position of the production line equipment (not shown in the figure); with the cooperation of the adjustment mechanism 6 and the lifting mechanism 4, the positioning accuracy of the AGV trolley is guaranteed to be within the range of 10-20mm, and the AGV trolley can also automatically dock with the discharge position of the production line equipment, and its positioning accuracy is guaranteed to be within ±5mm, ensuring that the material can be accurately received.

[0033] In another embodiment, a pair of relatively arranged positioning blocks 32 are provided on the docking end of the lifting platform 3, and a guide bevel 33 for guiding the AGV trolley is provided on the relatively close side of the positioning blocks 32 on both sides. Before controlling the first moving wheel 2 to rotate to drive the seat 1 to move to the specified position, the lifting mechanism 4 is first operated to control the lifting platform 3 to move upward a specified distance, and then the seat 1 is driven to move so that the lifting platform 3 is docked with the discharge position of the production line equipment. During the docking process, under the action of the positioning blocks 32, the AGV trolley is guided so that the lifting platform 3 is accurately docked with the discharge position of the production line equipment, thereby improving the accuracy of the docking. In addition, a pair of baffle plates 31 for preventing materials from escaping from the receiving mechanism 5 are provided on the top of the lifting platform 3, and the baffle plates 31 are respectively placed on both sides of the transport track of the receiving mechanism 5. In the process of receiving materials, the receiving mechanism 5 blocks the materials through the baffle plates 31 to prevent the materials from escaping from the receiving mechanism 5, so that the materials are stably placed on the receiving mechanism 5.

[0034] like Figure 3-4 As shown, the lifting mechanism 4 includes a support frame 41 installed on the vehicle seat 1, wherein a flange 42 is provided on the top of the support frame 41, and a lifting shaft 43 which is axially arranged vertically and can slide up and down is provided on the flange 42, and the top of the lifting shaft 43 is fixedly connected to the top of the groove 34 through a connecting block 412; by controlling the lifting shaft 43 to slide up and down on the flange 42, the lifting platform 3 is driven to move up and down on the vehicle seat 1. In order to accurately control the up and down movement distance of the lifting platform 3, a connecting frame 44 is provided at the bottom end of the lifting shaft 43, and a fixed block 48 with a slide groove is installed on the connecting frame 44, and the length direction of the slide groove on the fixed block 48 is arranged horizontally. In addition, a first servo motor 49 with a horizontally arranged output shaft is installed beside the support frame 41, and a swing block 410 is installed on the output shaft of the first servo motor 49. The first servo motor 49 is operated to drive the swing block 410 to swing; a roller 411 is rotatably provided on the swing end of the swing block 410, and the roller 411 is placed in the slide groove on the fixed block 48 to apply an upward force to the fixed block 48. The initial position of the roller 411 is at the lowest position. When the first servo motor 49 drives the swing block 410 to drive the roller 411 to swing, the roller 411 slides in the slide groove on the fixed block 48 and applies an upward force to the fixed block 48, thereby pushing the lifting shaft 43 to move upward and the lifting platform 3 to rise; and, by driving the swing block 410 to swing a certain angle through the first servo motor 49, the lifting shaft 43 can be controlled to move upward a specified distance, thereby realizing precise control of the up and down movement distance of the lifting platform 3.

[0035] In addition, a vertically arranged slide rail 45 is installed on the inner side wall of the support frame 41, and a first slider 46 is installed on the connecting frame 44. The first slider 46 is slidably set on the slide rail 45. Under the action of the slide rail 45 and the first slider 46, the lifting shaft 43 can slide up and down more stably; an infrared sensor 47 for detecting the position of the connecting frame 44 is also installed in the support frame 41. The infrared sensor 47 is used to detect the up and down movement distance of the connecting frame 44, thereby ensuring the accuracy of controlling the up and down movement of the lifting platform 3, so that the height error of the material receiving mechanism 5 and the discharge position of the production line equipment (not shown in the figure) is within ±5mm.

[0036] like Figure 5 As shown, the material receiving mechanism 5 includes a supporting cross bar 51 disposed on the top of the lifting platform 3, wherein a pair of rollers 52 arranged axially and horizontally are rotatably disposed on the supporting cross bar 51, and a conveying belt 53 for receiving materials is wound around the rollers 52, and a second servo motor 54 for driving one of the rollers 52 to rotate is also installed on the supporting cross bar 51. After the first moving wheel 2 rotates to drive the vehicle seat 1 to move and place it at a specified position, the jacking mechanism 4 is operated to control the lifting platform 3 to rise, thereby driving the conveying belt 53 to align with the discharge position of the production line equipment (not shown in the figure) and connect with it. When the material comes out, the second servo motor 54 is operated to drive the conveying belt 53 to move, thereby receiving the material coming out from the discharge position and conveying it to the lifting platform 3, completing the automatic reception of the material. Additionally, a drag plate 55 is mounted on the support cross bar 51 and is placed inside the material transport belt 53 and is used to tow up the material transport belt 53 . The drag plate 55 tows up the material transport belt 53 to prevent the material transport belt 53 from being deformed due to the heavy material.

[0037] like Figure 6-7As shown, the adjustment mechanism 6 includes a guide cylinder 61 installed on the seat 1 and arranged vertically, a lifting column 62 is provided in the guide cylinder 61 to slide up and down, and a support frame 67 is installed at the bottom end of the lifting column 62, and a plurality of second moving wheels 68 for driving the seat 1 to move are installed on the support frame 67, and the axial direction of the second moving wheel 68 is perpendicular to the axial direction of the first moving wheel 2. After the first moving wheel 2 rotates to drive the vehicle seat 1 (X axis) to move and place it in the specified position, the lifting mechanism 4 is operated to control the lifting platform 3 to rise, thereby driving the material transport belt 53 to align with the discharge position of the production line equipment (not shown in the figure) and connect with it; wherein, during the connection process, the position of the material transport belt 53 may deviate, resulting in failure to connect with the discharge position, and the lifting column 62 is controlled to slide downward in the guide cylinder 61, thereby moving downward with a number of second moving wheels 68, so that the second moving wheels 68 contact the ground, and then the lifting column 62 is controlled to move downward for a distance to lift the vehicle seat 1 and make the first moving wheel 2 leave the ground, and the vehicle seat 1 (Y axis) can be driven to move by the second moving wheel 68, thereby adjusting the position of the material transport belt 53 to connect with the discharge position of the production line equipment (not shown in the figure), and after the adjustment is completed, the lifting column 62 is controlled to reset upward, which further improves the docking accuracy of the AGV trolley.

[0038] In order to control the lifting column 62 to slide up and down in the guide cylinder 61, a screw rod 65 arranged axially and vertically is provided in the guide cylinder 61, and the screw rod 65 is threadedly connected to the lifting column 62. In addition, a third servo motor 66 is also installed on the vehicle seat 1, and the output end of the third servo motor 66 is connected to the bottom end of the screw rod 65; the screw rod 65 can be driven to rotate by running the third servo motor 66, so as to control the lifting column 62 to automatically slide up and down in the guide cylinder 61. In order to make the lifting column 62 slide up and down in the guide cylinder 61 more stably, a plurality of vertically arranged guide grooves 64 are formed on the side wall of the lifting column 62, and a plurality of guide bars 63 slidingly arranged with the guide grooves 64 are provided in the guide cylinder 61, and the guide bars 63 slide in the guide grooves 64; under the action of the guide grooves 64 and the guide bars 63, the lifting column 62 can slide up and down in the guide cylinder 61 more stably, and the lifting column 62 will not rotate, so as to ensure that the position of the second moving wheel 68 will not change.

[0039] In summary, it can be seen that the utility model has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.

[0040] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
