Description

Technical Field

[0001] This invention relates to the field of AGV equipment technology, specifically to a method for assembling a communication antenna for an AGV vehicle. Background Technology

[0002] With the continuous development of technology, automated transportation equipment has been widely adopted in the manufacturing and processing industry. Taking AGV (Automated Guided Vehicle) as an example, its connection end can now have functions such as automatic information identification, automatic positioning, and Bluetooth connection. The realization of these information transmission functions is mostly based on the communication antenna set inside it. This structure has greatly promoted the transportation efficiency in the industry.

[0003] Different communication antennas are required for different transportation mechanisms and types of transmitted signals. Currently, most industry manufacturers directly connect the communication antenna to the application equipment, treating it as an inseparable unit. Therefore, most current equipment has a single signal transmission function. Furthermore, if problems such as poor contact occur with the communication antenna, repair and replacement can only be done by completely disassembling the entire device. This integrated installation structure limits the versatility of the equipment, making each device compatible with only one type of transmission antenna. It also significantly increases the burden of equipment maintenance. Therefore, developing a universal signal transmission mechanism that can be easily disassembled is one of the urgent problems that the industry needs to solve. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problem that the signal transmission mechanism is difficult to repair and replace in the prior art, and to provide a method for assembling a communication antenna for an AGV vehicle.

[0005] To solve the above-mentioned technical problems, the present invention provides a method for assembling a communication antenna for an AGV (Automated Guided Vehicle). The AGV includes a quick-release universal signal transmission mechanism, which includes a mounting component and a communication antenna. The mounting component includes a base plate and at least one first connector, wherein the first connector is connected to the surface of the base plate, and the first connector and the base plate together form a connection cavity that can be detachably connected to an external applicable device. The communication antenna is mounted on the base plate through the first connector. The first connector includes a fixing part and a connecting part, wherein the fixing part extends perpendicularly to the base plate, and its free end connects to the connecting part. The connection includes a connection portion extending parallel to the substrate, and a connection cavity located between the substrate and the connection portion in the thickness direction of the quick-release universal signal transmission mechanism; a vehicle body with an antenna interface, the quick-release universal signal transmission mechanism being detachably connected to the antenna interface, the antenna interface including a first mounting portion disposed within the connection cavity, the communication antenna being disposed towards the interior of the vehicle body and the edge of the antenna interface being disposed within the connection cavity; and a signal receiving assembly including a transmission line and a signal receiver disposed within the vehicle body, one end of the transmission line contacting the communication antenna and the other end connected to the signal receiver.

[0006] The assembly method for the communication antenna of the AGV (Automated Guided Vehicle) includes the following steps: S1, the quick-release universal signal transmission mechanism is installed along the length direction of the antenna interface and inclined towards the inside of the vehicle body along the width direction of the vehicle body, ensuring that one of the first mounting parts is located in the connecting cavity. At this time, the AGV is in the first installation state; S2, the quick-release universal signal transmission mechanism is rotated around the rotation center line until the extension direction of the substrate is parallel to the longest diagonal of the antenna interface. At this time, the AGV is in the second installation state; S3, a force is applied to the quick-release universal signal transmission mechanism facing the outside of the vehicle body towards the inside of the vehicle body until the substrate is completely attached to the outer surface of the vehicle body. At this time, the AGV is in the third installation state; S4, the first connector is rotated in the opposite direction around the rotation center line, so that the extension direction of the quick-release universal signal transmission mechanism returns to the length direction of the antenna interface, and the communication antenna contacts the transmission line. The assembly process is now complete.

[0007] In one embodiment of the present invention, the mounting assembly includes two first connectors disposed at both ends of the substrate along its length, the two first connectors and the substrate forming two connecting cavities.

[0008] In one embodiment of the present invention, the mounting assembly further includes at least one second connector disposed on the first connector, and the communication antenna is rotatably connected to the second connector and spaced apart from the substrate.

[0009] In one embodiment of the present invention, the mounting assembly further includes a limiting member disposed on the edge of the substrate and on the same side as the first connector, and a portion of the limiting member protrudes from the substrate along the length / width direction of the substrate.

[0010] In one embodiment of the present invention, the limiting member includes an extension portion and a limiting portion, the extension portion extending perpendicularly to the surface of the substrate, and the limiting portion protruding from the substrate parallel to the surface of the substrate and along the width direction of the substrate.

[0011] In one embodiment of the present invention, the limiting member is configured as an integral arc-shaped element or a spherical element that can protrude from the periphery of the substrate.

[0012] In one embodiment of the present invention, the rotation center line is located at the center of the antenna interface and extends horizontally along the width direction of the vehicle body.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention. Example

[0026] This embodiment provides a method for assembling a communication antenna for an AGV (Automated Guided Vehicle). The AGV includes: a quick-release universal signal transmission mechanism; the quick-release universal signal transmission mechanism includes a mounting assembly 100, which includes a base plate 110 and at least one first connector 120, wherein the first connector 120 is connected to the surface of the base plate 110, and the first connector 120 and the base plate 110 together form a connection cavity 150 that can be detachably connected to an external applicable device; and a communication antenna 200, which is mounted on the base plate 110 via the first connector 120.

[0027] The vehicle body 300 has an antenna interface 310. A quick-release universal signal transmission mechanism is detachably connected to the antenna interface 310. The communication antenna 200 is positioned facing the interior of the vehicle body 300, and the edge of the antenna interface 310 is located inside the connection cavity 150. The signal receiving component includes a transmission line and a signal receiver disposed inside the vehicle body 300. One end of the transmission line is in contact with the communication antenna 200, and the other end is connected to the signal receiver.

[0028] The quick-release universal signal transmission mechanism in this embodiment enables rapid disassembly and installation between the communication antenna 200 and the device. It not only allows the device to be used with communication antennas 200 for different signals, but also eliminates the need to disassemble and damage the entire device during maintenance. This reduces costs and saves a lot of manpower and time, indirectly improving production efficiency. It is a new type of signal transmission mechanism with broad application prospects.

[0029] See Figure 1 and Figure 2 As shown, in this embodiment, the substrate 110 is configured as a flat, sheet-like racetrack-shaped element with different surface areas on opposite sides along its thickness direction. Specifically, with Figure 2 The quick-release universal signal transmission mechanism shown is a reference. In this embodiment, the side with the first connector 120 and the communication antenna 200 is a first surface with a relatively large surface area. The side opposite to the first surface along its thickness direction is the second surface. The first surface and the second surface are set as planes extending in the same direction and are fixedly connected to each other, forming an integral unit. The first surface can provide the maximum installation area. The shape of the second surface is the same as that of the first surface and is fixedly set at the center of the first surface. The two are connected by a slope extending from the outer edge of the first surface to the edge of the second surface. This structure can guide the specific installation direction during installation. In addition, since different connection structures can be set on opposite sides of the substrate 110, such as the first surface used to connect the first connector 120 and the communication antenna 200 in this embodiment, and the second surface is provided with installation orientation marks, etc., the mis-installation of components can be avoided during the manufacturing process. In other embodiments, the substrate 110 can be adjusted in shape and size according to the actual usage requirements. For ease of production and processing, the surfaces on opposite sides of the substrate 110 can also be configured with the same structure. This invention does not specifically limit this.

[0030] See Figure 1 and Figure 2As shown, the mounting assembly 100 includes two first connectors 120 disposed at both ends of the substrate 110 along its length, and the two first connectors 120 and the substrate 110 enclose two connecting cavities 150. In this embodiment, the two first connectors 120 are disposed at both ends of the second surface along the extension direction of the substrate 110, and the two first connectors 120 are symmetrically arranged around the center of the substrate 110. Further, in this embodiment, the first connector 120 includes a flat circular element that cooperates with the arc-shaped structure at both ends of the substrate 110. One side of the element is fixedly connected to the first surface of the substrate 110, and the opposite side is set as a plane extending in the same direction as the substrate 110 for connecting the communication antenna 200. Further, each first connector 120 includes a fixing part 121 and a connecting part 122, wherein the fixing part 121 is perpendicular to the substrate 110. The free end of the extension is connected to the connecting part 122, which extends parallel to the substrate 110. In the thickness direction of this quick-release universal signal transmission mechanism, the connecting cavity 150 is located between the substrate 110 and the connecting part 122. It is configured as an arc-shaped cavity with one end communicating with the outside. Furthermore, in this embodiment, the fixing part 121 and the connecting part 122 are fixedly connected and are actually integrally set. The fixing part 121 and the substrate 110 are also fixedly connected. In other embodiments, the fixing part 121 and the connecting part 122 and / or the substrate 110 can be configured as a detachable connection structure for easy disassembly. In this embodiment, the fixing part 121 is configured as a flat circular element with a diameter smaller than that of the connecting part 122, and it is attached to the surface of the substrate 110. On the one hand, the fixing part 121 is used to fix the connecting part 122 to the substrate 110. On the other hand, the difference in the outer diameter of the fixing part 121 and the connecting part 122 forms a connecting cavity 150 in the thickness direction of this quick-release universal signal transmission mechanism for connecting with an external applicable device. When this quick-release universal signal transmission mechanism is connected to an external applicable device, the edge of the device connection can be inserted into the connecting cavity 150, and its opposite sides are simultaneously stopped by the connecting part 122 and the substrate 110. This not only achieves a stable connection with the external device, but also allows the device to receive signals during use or installation. The force is evenly distributed into the two connecting cavities, thereby extending the service life of this quick-release universal signal transmission mechanism. Specifically, in this embodiment, two connecting cavities 150 are symmetrically provided corresponding to the two first connecting members 120. Thus, this quick-release universal signal transmission mechanism can achieve connection and fixation at both opposite ends simultaneously, further improving the practicality of this quick-release universal signal transmission mechanism and its stability during use. In addition, in other embodiments, in order to reduce production costs and processing difficulty, only one first connecting member 120 may be provided, or, in order to further improve its connection stability, multiple first connecting members 120 may be provided on the outer periphery of the substrate 110. The present invention does not limit the number, connection method, or specific shape of the first connecting members 120.

[0031] See Figure 1 and Figure 2 As shown, the mounting assembly 100 also includes at least one second connector 130, which is disposed on the first connector 120. The communication antenna 200 is rotatably connected to the second connector 130 and spaced apart from the substrate 110. In this embodiment, a second connector 130 is connected to one of the first connectors 120 to fix the communication antenna 200 to the first connector 120. Specifically, in this embodiment, the main body of the second connector 130 is vertically connected to the surface of the first connector 120, and a clearance groove is provided at its free end for the communication antenna 200 to pass through. The communication antenna 200 can rotate in the clearance groove to adjust its specific angle during installation. This structure can ensure that the communication antenna 200 can contact the receiving device to realize the signal transmission function, and can also avoid mutual contact and squeezing due to the small distance between them, thereby reducing the problem of bending damage to the communication antenna 200 during installation.

[0032] See Figure 1 and Figure 2 As shown, the mounting assembly 100 also includes a limiting member 140, which is disposed on the edge of the substrate 110 and on the same side as the first connecting member 120. Part of the limiting member 140 protrudes from the substrate 110 along its length / width direction. In this embodiment, the limiting member 140 is disposed on one side of the substrate 110 in the width direction and is specifically connected to the center of the substrate 110 in the length direction. The limiting member 140 is used to further improve the connection stability between the quick-release universal signal transmission mechanism and the external device after the latter is installed. It can fix the connection structure after installation from another direction. Specifically, in this embodiment, the limiting member 140 and the two connecting cavities 150 can simultaneously limit and fix the substrate 110 in both the length and width directions, thereby ensuring its stability during use. In other embodiments, the limiting member 140 may also be disposed at other positions on the substrate 110 or its quantity may be set to two or more. This invention does not limit this.

[0033] See Figure 1As shown, the limiting member 140 includes an extension 141 and a limiting member 142. The extension 141 extends perpendicularly to the surface of the substrate 110, and the limiting member 142 is parallel to the surface of the substrate 110 and protrudes from the substrate 110 along the width direction of the substrate 110. In this embodiment, the extension 141 is disposed perpendicularly to the surface of the substrate 110, and its free end is connected to the limiting member 142 which extends horizontally toward the outside of the substrate 110. Furthermore, in this embodiment, at least a portion of the limiting member 142 protrudes horizontally from the periphery of the substrate 110. Thus, it can restrict the quick-release universal signal transmission mechanism in the installation direction, thereby achieving its connection and fixation function. Specifically, in this embodiment, the connecting part 122 and the fixing part 121 are fixedly connected and are actually integrally disposed. In other embodiments, the limiting member 140 can also be configured as other structures that can protrude from the periphery of the substrate 110, such as an integral arc-shaped element, a spherical element, etc.

[0034] See Figure 3 As shown, in this embodiment, the antenna interface 310 is located in the middle of the side wall on one side of the vehicle body 300. It is configured as an opening that can abut against and cooperate with the quick-release universal signal transmission mechanism and penetrate the internal and external environment of the vehicle body 300. The receiving end of the transmission line is located inside the vehicle body 300 where the antenna interface 310 is located, and it is spaced apart from the vehicle body 300. In this embodiment, the communication antenna is a Bluetooth antenna, and the receiver is preferably a Bluetooth signal receiver. Furthermore, the vehicle body 300 in this embodiment is a steel component. Therefore, the quick-release universal signal transmission mechanism is preferably made of low-density nylon material as the carrier substrate to avoid shielding effect between it and the vehicle body 300, which would lead to poor signal transmission.

[0035] In this embodiment, see Figure 4 As shown, the antenna interface 310 includes a first mounting portion 311 disposed within the connecting cavity 150 and a second connecting portion 122 capable of cooperating with the limiting member 140. Specifically, to Figure 3Using the AGV trolley shown as a reference, the first mounting part 311 is disposed at both ends of the antenna interface 310 along its length and is configured as an arc-shaped structure that cooperates with the connecting cavity 150. The second connecting part 122 is preferably a rectangular hollow structure with a spacing distance not greater than the width of the substrate 110 and not less than the thickness of the substrate 110. The first connecting part 122 and the second connecting part 122 are fixedly connected. Further, this embodiment includes two first connecting parts 122, and the two first connecting parts 122 are respectively located between the two connecting cavities 150. The second connecting part 122 is located between the limiting part 142 and the substrate 110 in the width direction of the vehicle body 300. Thus, the first connecting part 122 realizes a stable connection of this quick-release universal signal transmission mechanism in the height direction of the vehicle body 300, and the second connecting part 122 realizes a stable connection in the length direction of the vehicle body 300. In other embodiments, this quick-release universal signal transmission mechanism can be flexibly disassembled by different signal receivers installed inside it, and the communication antenna 200 installed on it can be replaced to make it suitable for different devices. When the signal transmission is unstable or components such as transmission lines need to be repaired or replaced, the corresponding components can also be exposed by disassembling this quick-release universal signal transmission mechanism, so as to achieve the purpose of repairing and replacing components without disassembling the vehicle body 300.

[0036] In summary, the AGV provided in this embodiment enables rapid disassembly and installation between the communication antenna 200 and the equipment. This not only allows the equipment to be used with different signal communication antennas 200, but also eliminates the need to disassemble and damage the entire equipment during maintenance. This reduces costs and saves a significant amount of manpower and time, indirectly improving production efficiency. It is a new type of AGV with broad application prospects.

[0037] This embodiment provides a method for assembling a communication antenna for an AGV (Automated Guided Vehicle), specifically including the following steps:

[0038] S1. The quick-release universal signal transmission mechanism is positioned along the length of the antenna interface 310 and inclined towards the interior of the vehicle body 300 along the width of the vehicle body 300, passing through the antenna interface 310 to ensure that one of the first mounting parts 311 is located within the connecting cavity 150. At this time, the AGV is in the first mounting state. See Figure 3 As shown, the quick-release universal signal transmission mechanism and the antenna interface 310 are relatively independent. Before installation, it is necessary to ensure that the main extension directions of the two are the same, and the side connected to the communication antenna 200 should be facing the inside of the vehicle body. After confirming the above direction, the quick-release universal signal transmission mechanism needs to be inserted into the antenna interface 310 at an angle, so that one of the first mounting parts 311 is inserted into the connecting cavity 150 and at least a part of the base plate 110 is located inside the vehicle body 300.

[0039] S2. Rotate the quick-release universal signal transmission mechanism around the rotation center line 1001 until the extension direction of the substrate 110 is parallel to the longest diagonal of the antenna interface 310. At this point, the AGV is in the second installation state. See also Figure 5 As shown, in this embodiment, the rotation center line 1001 is set at the center of the antenna interface 310 and extends horizontally along the width direction of the vehicle body 300. When the extension direction of the quick-release universal signal transmission mechanism is parallel to the longest diagonal of the antenna interface 310, it is located at the position where it is easiest to connect to the antenna interface 310. At this position, the operator can fasten the quick-release universal signal transmission mechanism to the antenna interface 310 with minimal force.

[0040] S3. Apply a force towards the inside of the vehicle body 300 to the quick-release universal signal transmission mechanism facing the outside of the vehicle body 300 until the substrate 110 is completely attached to the outer surface of the vehicle body 300. At this time, the AGV is in the third installation state. In this embodiment, both first connectors 120 are located inside the antenna interface 310 and the vehicle body 300. At this time, there is no tilt angle between the quick-release universal signal transmission mechanism and the vehicle body 300. The first connectors 120 and the substrate 110 are respectively disposed on the inner and outer sides of the vehicle body 300. At this time, the communication antenna 200 is located in the same plane as the transmission line along the width direction of the vehicle body 300.

[0041] S4. Rotate the first connector 120 in the opposite direction around the rotation center line 1001, so that the extension direction of the quick-release universal signal transmission mechanism returns to the length direction of the antenna interface 310, and the communication antenna 200 contacts the transmission line. At this time, the AGV trolley is in the assembled state. See Figure 6 As shown, when the assembly is complete, both first connecting parts 311 are located inside the corresponding connecting cavities 150, the second connecting part 122 is located between the limiting member 140 and the substrate 110, and the communication antenna 200 and the signal receiver complete the signal connection, thus completing the assembly process. When disassembly is required, simply reverse the above operation.

[0042] In summary, the quick-release universal signal transmission mechanism of the present invention enables rapid disassembly and installation between the communication antenna 200 and the device being used. This not only allows the device to be used with different signal communication antennas 200, but also eliminates the need for complete disassembly and damage to the device during maintenance, reducing costs and saving significant manpower and time, thus indirectly improving production efficiency. This assembly method enables rapid disassembly and installation between the communication antenna 200 and the device being used, making the device suitable for different signal communication antennas 200. Furthermore, it eliminates the need for complete disassembly and damage to the device during maintenance, reducing costs and saving significant manpower and time, thus indirectly improving production efficiency. It is a novel assembly method that can improve production line efficiency and enhance the versatility of equipment functions.

[0043] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
