[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] Please refer to Figures 1-7. This invention provides a technical solution for a light steel keel splicing system based on an AGV (Automated Guided Vehicle) vehicle, comprising: an AGV intelligent transport vehicle 1A, a keel assembly platform 2A, and a positioning device 3A; the positioning device 3A further defines a first coordinate system, wherein the first coordinate system is defined with the assembly surface on the keel assembly platform 2A as the XY-axis plane S2, and the axis perpendicular to the XY-axis plane S2 as the Z-axis, and the midpoint of the side of the assembly surface near the first region S1 as the origin O; the positioning device 3A is further used to determine the relative position of the AGV intelligent transport vehicle 1A in the first coordinate system;

[0036] The AGV intelligent transport vehicle 1A is used to acquire different light steel keels 1 in the first area S1 according to the assembly sequence; and to adjust the angle and height of the corresponding light steel keel 1 in the first area S1 according to the angle and height information of the corresponding light steel keel 1, wherein the adjustment of the angle and height is completed with reference to the first coordinate system;

[0037] The AGV intelligent transport vehicle 1A is further used to transfer the adjusted light steel keel 1 to the corresponding position on the keel assembly platform 2A and lock it in place.

[0038] In one embodiment, to address the problem of accurate positioning of AGVs in complex environments in the prior art, an initial position node 31A is set at the midpoint of one side of the first area S1, and several regularly distributed sub-position nodes 32A are established on the keel assembly platform 2A. The AGV intelligent transport vehicle 1A moves to the initial position node 31A, causing the positioning device 3A to initialize and begin constructing the first coordinate system, ensuring that the origin O corresponds to the initial position node 31A and that the first coordinate system covers all the sub-position nodes 32A. By setting the initial position node 31A and the sub-position nodes 32A, a clear reference system, namely the first coordinate system, is provided for the AGV intelligent transport vehicle 1A. Initializing the positioning device 3A, ensuring that the origin O corresponds to the initial position node 31A, and that the first coordinate system covers all the sub-position nodes 32A, ensures the accurate positioning of the AGV intelligent transport vehicle 1A within the system. The initial position node 31A and the sub-position nodes 32A can be implemented using existing Bluetooth tags, magnetic nails, landmarks, and other radio frequency devices. The initial position node 31A and the sub-position node 32A can be at least partially fixed on the keel assembly platform 2A, thereby preventing changes in the actual position caused by changes in the position of the keel assembly platform 2A.

[0039] Referring to Figure 8, in one embodiment, it includes an initial position node 31A and three sub-position nodes 32A; the initial position node 31A is located at the midpoint of one side of the first region S1 facing the XY axis plane S2, and the three sub-position nodes 32A are located at the three corners of the keel assembly platform 2A.

[0040] In other embodiments, the device for constructing and positioning the first coordinate system can also be selected according to actual needs, as long as it can achieve accurate positioning between the AGV intelligent transport vehicle 1A and the keel assembly platform 2A, and no restrictions are imposed here.

[0041] To address the issues of inaccurate tag reading or inability to update location information in real time in existing technologies, the positioning device 3A can employ existing technologies such as laser navigation, visual navigation, electromagnetic navigation, magnetic strip / magnetic nail navigation, landmark navigation, ultrasonic positioning, or Bluetooth 5.1 positioning. Laser navigation technology uses reflectors installed around the AGV's travel path; a laser scanner emits a laser beam and receives the reflected signal, calculating the reflection angle to determine the AGV's position. This method offers high precision and flexibility, suitable for complex and changing environments. Visual navigation uses image acquisition devices such as cameras to obtain environmental image information and uses deep learning and image recognition algorithms to identify features such as landmarks, symbols, or QR codes, achieving autonomous positioning and navigation. Electromagnetic navigation uses metal wires laid along the path and low-frequency current applied to generate a magnetic field; electromagnetic sensors on the AGV navigate by sensing this magnetic field. Magnetic strip / magnetic nail navigation technology involves laying magnetic strips or installing magnetic nails along the AGV's travel path; magnetic induction sensors at the bottom of the AGV detect magnetic signals to determine its position.

[0042] In one embodiment, the positioning device 3A, the initial position node 31A, and the three sub-position nodes 32A can be constructed using a Bluetooth positioning system, such as Bluetooth 5.0 or Bluetooth 6.0 technology. Specifically, referring to Figure 8, a Bluetooth base station is built on the XY-axis plane S2, and Bluetooth tags are set on the AGV intelligent transport vehicle 1A, the initial position node 31A, and the sub-position nodes 32A. By transmitting radio frequency signals, nearby Bluetooth tags are activated, and data is read or written from the Bluetooth tags, thereby obtaining the position of the AGV intelligent transport vehicle 1A, the initial position node 31A, and the sub-position nodes 32A, and updating them in real time.

[0043] In one embodiment, to achieve automated production and assembly of light steel keel 1 in a factory, a light steel keel forming device 4A is included. This device generates different light steel keels 1 according to the assembly sequence. The light steel keel forming device 4A can automatically produce light steel keels 1 according to a predetermined assembly sequence, improving production efficiency. The AGV intelligent transport vehicle 1A is used to acquire the light steel keels 1 sequentially formed by the light steel keel forming device 4A at the first area S1. For example, in one embodiment, it is necessary to produce light steel keels of models 1#, 2#, 1#, 3#, 2#, 2#, 1#, 3#, 2#, and 4# in sequence. In this case, the light steel keel forming device 4A can produce them in a predetermined order. After production, the AGV intelligent transport vehicle 1A sequentially grabs and acquires their corresponding angle, height, and position information, and transports them to a designated location according to this specified information.

[0044] In other embodiments, to address the issue of automating the assembly of light steel keel 1 on construction sites, a light steel keel storage device 5A is also included. This device stores different models of light steel keel 1, and each light steel keel 1 is equipped with a keel tag 33A. The keel tag 33A records key information such as the model and size of the light steel keel 1, facilitating identification and handling by the AGV intelligent transport vehicle 1A. Furthermore, the light steel keel 1 storage device can systematically store and manage different models of light steel keel 1, improving the system's flexibility and scalability. The camera component and / or RFID reader read the keel tag 33A. Then, in the first area S1, the light steel keel 1 in the light steel keel 1 storage device is received sequentially. Through tag management and orderly storage, the system's operating efficiency and accuracy are improved.

[0045] Preferably, the keel tag 33A includes a QR code, barcode, or RFID tag; and the AGV intelligent transport vehicle has a camera component and an RFID reader; in one embodiment, the keel tag 33A is equipped with an RFID tag; and the AGV intelligent transport vehicle has an RFID reader. By reading the RFID tag of the keel tag 33A through the RFID reader on the AGV intelligent transport vehicle, information about the keel can be obtained, including: length, material, model, and assembly order, angle, and position. At this time, the AGV intelligent transport vehicle can grab the corresponding keel according to the keel information. For example, in one embodiment, it is necessary to obtain light steel keels of models 1#, 2#, 1#, 3#, 2#, 2#, 1#, 3#, 2#, and 4# in sequence for assembly. At this time, the AGV intelligent transport vehicle can read and grab the corresponding model of light steel keel in sequence, and then transport it to the designated position for assembly.

[0046] To address the issues of limited label types and poor recognition performance in existing technologies, the camera component includes a high-resolution camera and an image processing unit. When the camera scans the QR code or the barcode, the image processing unit parses the information of the keel in the QR code or the barcode and transmits it to the AGV intelligent transport vehicle 1A to grasp the light steel keel 1.

[0047] In other embodiments, specifically, the AGV intelligent transport vehicle 1A includes:

[0048] The gripping mechanism 2 binds the keel 1;

[0049] The lifting mechanism 3 changes the position and height of the restrained keel 1;

[0050] The rotating mechanism 4 drives the bound keel 1 to rotate, adjusting the angle and posture of the keel 1;

[0051] AGV moving mechanism 5 is used to move the keel 1 to the target area;

[0052] The gripping mechanism 2 includes a platform 21, a sliding component 22, and a clamping component 23.

[0053] The AGV moving mechanism 5 can be based on existing technology and can be purchased directly from the market. Therefore, its structure will not be described in detail in this specification.

[0054] In one embodiment, the AGV moving mechanism 5 moves to the target area, the gripping mechanism 2 binds the keel 1, the rotating mechanism 4 adjusts the angle and posture of the keel 1, and the lifting mechanism 3 lifts the keel 1 to the target height. Then, manual welding or other fixing devices are used to fix and assemble the keel 1.

[0055] Furthermore, to reduce friction between the keel 1 and the platform 21, the sliding component 22 is rolled on the platform 21 to provide rolling support for the keel 1. In one embodiment, the sliding component 22 includes a plurality of balls 222 connected in series by rollers 221. The rollers 221 are rotatably mounted inside the platform 21 via bearings, and the balls 222 partially protrude from the platform 21. The use of balls 222 ensures point contact with the keel 1, which greatly reduces wear compared to surface contact and improves wear resistance and durability. At the same time, the design of a plurality of balls 222 connected in series by rollers 221 not only disperses the pressure of the keel 1 on the platform 21, but also enhances the load-bearing capacity of the keel 1, so that the keel 1 can remain stable when moving and is not prone to displacement or tilting.

[0056] Furthermore, to stably bind the keel 1, the clamping assembly 23 clamps the keel 1, fixing it to the platform 21. In one embodiment, the clamping assembly 23 includes a groove pre-reserved on the platform 21, two bases 232 with several clamping elements 231 installed, a slide rail 233 for slidingly mounting the bases 232, and a screw mechanism 234. The screw mechanism 234 drives the bases 232 to move along the slide rail 233. This operation simplifies the clamping process and improves work efficiency. The two bases 232 are threadedly connected to the screw mechanism 234. In the opposite direction, the two bases 232 move in opposite directions when the lead screw mechanism 234 is running. This clamping method allows the clamping assembly 23 to adapt to keels 1 of different sizes, improving the versatility and adaptability of the system. Furthermore, the use of the lead screw mechanism 234 makes the movement of the bases 232 easy and quick. By simply operating the lead screw mechanism 234, the two bases 232 can move simultaneously in opposite directions, using the clamping members 231 to clamp the keel 1. The clamping members 231 on the two bases 232 clamp the keel 1 to complete the fixed binding of the keel 1, ensuring that the keel 1 will not shift or shake during use.

[0057] Furthermore, to enhance the binding force and binding surface of the clamping member 231 on the keel 1, each clamping member 231 has two nodes protruding from the platform 21; the clamping member 231 moves along the slide groove; the two protruding nodes are distributed along the slide groove, so that when the keel 1 needs to be clamped, the force is applied by the adjacent node, and for some hollow keels 1, the other node can expand the internal structure of the keel 1, so that this type of keel 1 can also be fixed to the platform 21; and the design of two nodes expands the range of action of the clamping member 231 and shortens the working cycle of the lead screw mechanism 234.

[0058] The lifting mechanism 3 includes an electric push cylinder located below the platform 21, which drives the gripping mechanism 2 to move up and down.

[0059] The rotating mechanism 4 includes a motor located below the lifting mechanism 3; the motor drives the lifting mechanism 3 and the gripping mechanism 2 to rotate.

[0060] The screw mechanism described in this patent is a horizontally placed screw jack.

[0061] Working principle: The AGV moving mechanism 5 moves to the target area, and the keel 1 pushed by the light steel keel forming device 4A moves along the sliding component 22 on the platform 21. Then, the screw mechanism 234 drives the base 232 and the clamping component 231 to clamp and bind the keel 1. Then, the rotating mechanism 4 adjusts the angle and posture of the keel 1, and the lifting mechanism 3 lifts the keel 1 to the target height. Finally, the welding and assembly are completed manually.

[0062] Example 1

[0063] A light steel keel splicing system based on AGV carts includes an AGV intelligent transport vehicle 1A, a keel assembly platform 2A, a positioning device 3A, and a light steel keel forming device 4A.

[0064] First, an initial position node 31A is set on one side of the keel assembly platform 2A, and several sub-position nodes 32A are regularly distributed on the assembly surface.

[0065] The AGV intelligent transport vehicle 1A moves to the initial position node 31A, and the positioning device 3A is activated to initialize and construct a first coordinate system with the assembly surface as the XY axis plane S2 and the axis perpendicular to the XY axis plane S2 as the Z axis. The origin O is set at the midpoint of the side of the assembly surface close to the first area S1, and the first coordinate system is ensured to cover all sub-position nodes 32A.

[0066] The light steel keel forming device 4A produces different light steel keels 1 according to the predetermined assembly sequence. After the AGV intelligent transport vehicle 1A receives the keel, it automatically obtains the set position, angle and height information of the keel.

[0067] Subsequently, based on this information, the AGV intelligent transport vehicle 1A adjusts the angle and height of the light steel keel 1 in the first area S1, and the adjustment process is completed with reference to the first coordinate system.

[0068] After adjustment, the AGV intelligent transport vehicle 1A uses its own gripping mechanism to bind the light steel keel 1, and uses the lifting and rotating mechanisms to ensure that it is in the correct position and posture.

[0069] Afterwards, the AGV intelligent transport vehicle 1A transfers the light steel keel 1 to the corresponding position on the keel assembly platform 2A and locks it in place using a locking device; this process realizes the automated and precise splicing of the light steel keel 1.

[0070] Example 2

[0071] Based on Example 1, this embodiment adds a storage device for the light steel keel 1 and optimizes the reading method of the keel label 33A.

[0072] The newly added light steel keel 1 storage device in the system is used to store various models of light steel keel 1. Each light steel keel 1 is attached with a keel label 33A containing model and assembly sequence information (a QR code label is used in this embodiment).

[0073] When it is necessary to assemble a certain type of light steel keel 1, the AGV intelligent transport vehicle 1A first moves to the storage device of the light steel keel 1, and scans the QR code label through the camera component on it to obtain the model and assembly sequence information of the light steel keel 1.

[0074] Subsequently, the AGV intelligent transport vehicle 1A, according to the assembly sequence information, sequentially receives the corresponding light steel keel 1 in the light steel keel 1 storage device and transports it to the first area S1 for angle and height adjustment. The adjustment process is the same as in Embodiment 1, and is completed with reference to the first coordinate system.

[0075] After the adjustment is completed, the AGV intelligent transport vehicle 1A will transfer the light steel keel 1 to the corresponding position on the keel assembly platform 2A and lock it in place.

[0076] By introducing a storage device for the light steel keel 1 and a QR code label reading method, this embodiment further improves the automation and flexibility of splicing the light steel keel 1.
