[0002] In the manufacturing process of FPC and PCB boards, long-distance transport of long carriers is required to complete different processing steps. Currently, most common transport guide structures use belt conveyors; however, this method has significant limitations: firstly, belt conveyors have limited load capacity and are prone to slippage and deformation when handling heavy, long carriers, leading to unstable transport; secondly, belts wear out quickly with frequent use, requiring frequent replacement, increasing equipment maintenance costs and downtime. Therefore, a new type of transport guide structure is urgently needed to solve these problems. Utility Model Content

The positioning detection mechanism and the blocking mechanism are located in the output direction of the conveying mechanism. The positioning detection mechanism detects and provides feedback on the position information of the vehicle, and the blocking mechanism prevents the vehicle that has reached the positioning detection mechanism from continuing to be transported.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0025] like Figure 1 and Figure 2 As shown, a novel transport guide structure includes a conveying mechanism 1, a positioning detection mechanism 2, a blocking mechanism 3, and a pressing mechanism 4. The conveying mechanism 1 includes a drive unit 11, a transmission assembly 12, and a chain track assembly 13. The transmission assembly 12 uses gear transmission. The chain track assembly 13 is installed and laid out according to the production line layout. The drive unit 11 is connected to the chain track assembly 13 through the transmission assembly 12 to drive the chain track assembly 13 to transport the carrier 5. The positioning detection mechanism 2 and the blocking mechanism 3 are located in the output direction of the conveying mechanism 1. The positioning detection mechanism 2 uses a photoelectric sensor, located below the running path of the carrier 5, to detect and feedback the position information of the carrier 5. When the carrier 5, transported by the conveying mechanism 1, reaches the positioning detection mechanism 2, the positioning detection mechanism 2 can promptly detect the position of the carrier 5 and feed the position information back to the control system. The blocking mechanism 3 is used to prevent the carrier 5 from continuing to be transported after reaching the positioning detection mechanism 2, ensuring that the carrier 5 can accurately stop at the designated position. The pressing mechanism 4 is used to press down the stopped carrier 5 to achieve positioning.

[0026] It is understandable that the novel transport guide structure of this application requires a control system to operate in practical applications. The control system, as the core hub of the entire transport guide structure, uses a programmable logic controller (PLC) or an industrial computer as the main control unit. After receiving the signal from the positioning detection mechanism 2, the control system coordinates the actions of each actuator according to the preset logic program and priority order. Furthermore, the built-in closed-loop feedback mechanism of the control system monitors the execution status of each mechanism in real time. If an abnormality occurs, such as the blocking mechanism 3 failing to operate normally, the system will trigger an alarm and suspend operation. In addition, the control system also supports data interaction with external devices via industrial communication protocols, facilitating integration into larger automated production lines and enabling remote monitoring and parameter adjustment. Specifically, the working coordination process of each mechanism in the novel transport guide structure of this application is as follows:

[0027] The conveying mechanism 1 continuously transports the long carriers 5, such as FPCs and PCBs, along their running direction, ensuring smooth movement of the carriers 5 on the guide rails. The arrival detection mechanism 2 uses photoelectric sensors, proximity switches, and other sensing elements to monitor in real time whether the carriers 5 have reached the designated position. When the carrier 5, transported by the chain track assembly 13, reaches the arrival detection mechanism 2, the detection mechanism detects the carrier 5 and immediately sends a signal to the control system. Upon receiving the signal, the control system issues a command to control the blocking mechanism 3 to operate, preventing the carrier 5 from continuing forward and ensuring it precisely stops at the predetermined workstation; simultaneously, it also issues a command to control the conveying mechanism 1 to pause transport. After the carrier 5 is blocked and fixed, the control system also issues a command to control the pressing mechanism 4 to press and fix the carrier 5 firmly onto the conveying mechanism 1, achieving precise positioning of the carrier 5 and preventing displacement during subsequent operations. This allows the control system to issue commands to control other subsequent processing mechanisms to perform processing operations on the carrier 5. After processing is completed, the control system issues another command to reset the blocking mechanism 3 and the pressing mechanism 4, and controls the conveying mechanism 1 to continue running to send the carrier 5 out of the transport guide structure.

[0028] like Figure 1 and Figure 2 As shown, in this embodiment, the conveying mechanism 1 is the core power transmission part of the entire transport guide structure, which includes a drive device 11, a transmission assembly 12, and a chain track assembly 13. The drive device 11 is connected to the chain track assembly 13 through the transmission assembly 12. When the drive device 11 is working, it transmits power to the chain track assembly 13 through the transmission assembly 12, thereby driving the chain track assembly 13 to operate and transport the carrier 5. The conveying mechanism 1 also includes an oil collection box 14, which is used to collect the lubricating oil dripping from the chain track assembly 13 during operation, preventing the lubricating oil from contaminating the working environment and the carrier 5, and ensuring the cleanliness and safety of the transportation process. Compared with the traditional belt conveyor structure, the chain track assembly 13 used in the conveyor mechanism 1 of this application has significant advantages: (1) Stronger load capacity: The chain is made of metal material, which can withstand greater weight and impact force, and is suitable for heavy-duty working conditions, while the belt is prone to stretching deformation or breakage due to overload; (2) Higher transmission accuracy: The meshing transmission method of the chain and sprocket avoids problems such as slippage and elastic deformation in belt transmission, ensuring accurate positioning of the carrier 5, and is suitable for automated production scenarios with high transmission accuracy requirements; (3) Superior durability and stability: The chain structure is wear-resistant and corrosion-resistant, and is less affected by environmental factors such as temperature, humidity and dust, with a long service life and long maintenance cycle; the belt is prone to aging and wear, and needs to be replaced frequently; (4) Applicable to complex environments: It can operate stably in harsh environments such as high temperature, low temperature, and oil pollution, while the performance of the belt will drop significantly in these environments; (5) Flexible transmission direction: It can realize multi-directional combination transmission such as horizontal, vertical, and inclined, and meet the complex space conveying needs through the chain track layout design, while the belt transmission direction is relatively limited.

[0029] The advantages of the novel transport guide structure in this embodiment are: by optimizing the design and cooperation of the conveying mechanism 1, the arrival detection mechanism 2, the blocking mechanism 3 and the pressing mechanism 4, the carrier 5 can be accurately transported and reliably positioned, thereby improving the stability and accuracy of the transport process and meeting the needs of scenarios such as automated production.

[0030] like Figure 2 As shown, in this embodiment, the blocking mechanism 3 includes an inner track blocking component 31 and an outer track blocking component 32. The positioning detection mechanism 2 is configured to cooperate with the inner track blocking component 31 and the outer track blocking component 32 in a corresponding manner. Specifically, the blocking mechanism 3 is divided into an inner track blocking component 31 and an outer track blocking component 32 to accommodate vehicles 5 of different lengths. Shorter vehicles 5 are blocked by the inner track blocking component 31, while longer vehicles 5 are blocked by the outer track blocking component 32. In use, the inner track blocking component 31 or the outer track blocking component 32 can be flexibly called by the control system according to the actual length of the vehicle 5 to achieve precise positioning of the vehicle 5. At the same time, multiple sets of positioning detection mechanisms 2 are provided, the number of which corresponds to the total number of inner track blocking components 31 and outer track blocking components 32 in the blocking mechanism 3. The positioning detection mechanisms 2 are distributed inside the track and at the end of the track, and their positions correspond to the inner track blocking component 31 and the outer track blocking component 32, respectively, to achieve precise cooperation and real-time monitoring of the precise position of the vehicle 5.

[0031] like Figure 3 As shown, in this embodiment, the inner track blocking assembly 31 includes a base 311, a lifting cylinder 312, a lifting guide rail 313, and a blocking member 314. The base 311 is installed on the outside of the conveying mechanism 1, providing a mounting base for other components. The lifting cylinder 312 and the lifting guide rail 313 are installed on the base 311, and the blocking member 314 is slidably connected to the lifting guide rail 313, and the blocking member 314 is connected to the output end of the lifting cylinder 312. It should be noted that when the inner track blocking assembly 31 is in its initial state, the blocking member 314 is located above the chain track assembly 13, and the carrier 5 can pass normally under the blocking member 314; when it is necessary to block the carrier 5, the lifting cylinder 312 drives the blocking member 314 to descend along the lifting guide rail 313 into the chain track assembly 13, preventing the carrier 5 from continuing to move forward; when the carrier 5 needs to continue conveying, the lifting cylinder 312 drives the blocking member 314 to rise, resetting it above the chain track assembly 13, without affecting the operation of the carrier 5.

[0032] like Figure 4As shown, in this embodiment, the track end blocking assembly 32 includes a mounting base 321, a telescopic cylinder 322, a telescopic guide rail 323, a slider 324, and a telescopic member 325. The mounting base 321 is mounted on the outer side of the end of the conveying mechanism 1. The telescopic cylinder 322 and the telescopic guide rail 323 are mounted on the mounting base 321. The slider 324 is slidably connected to the telescopic guide rail 323 and is connected to the output end of the telescopic cylinder 322. The telescopic member 325 is fixedly connected to the slider 324. The telescopic cylinder 322 drives the slider 324 to slide, so that the telescopic member 325 extends to the end of the conveying mechanism 1, blocking the carrier 5 that reaches the end of the conveying mechanism 1 and restricting the carrier 5 from continuing to convey. When it is necessary to release the carrier 5, the telescopic cylinder 322 drives the telescopic member 325 to retract, so that the carrier 5 can leave smoothly.

[0033] In this embodiment, the drive device 11 uses a stepper motor. Stepper motors are characterized by high precision and the ability to accurately control rotation angle, speed, and direction, and can easily switch rotation directions. By switching the rotation direction of the drive device 11, the operating and conveying direction of the chain track assembly 13 can be changed, enabling the transport guide structure to achieve bidirectional transport. This meets the diverse needs of different production processes for the conveying direction of the carrier 5, enhancing the applicability and flexibility of the transport guide structure. Simultaneously, to achieve bidirectional transport and blocking positioning of the carrier 5, this embodiment provides two sets of both the arrival detection mechanism 2 and the blocking mechanism 3, which are paired and located at the front and rear ends of the conveying mechanism 1. By setting mutually cooperating arrival detection mechanisms 2 and blocking mechanisms 3 in both the forward and reverse transport directions of the conveying mechanism 1, dynamic detection and real-time blocking control can be achieved regardless of which direction the carrier 5 enters the transport path. This is suitable for applications such as automated production lines and logistics sorting systems where bidirectional transport positioning accuracy is critical.

[0034] like Figure 5 As shown, in this embodiment, the pressing mechanism 4 includes a fixed base 41, upper and lower cylinders 42, upper and lower guide rails 43, and a pressing member 44. The fixed base 41 is installed on the outside of the conveying mechanism 1. The upper and lower cylinders 42 and the upper and lower guide rails 43 are installed on the fixed base 41. The pressing member 44 is slidably connected to the upper and lower guide rails 43 and is connected to the output end of the upper and lower cylinders 42. When the carrier 5 is accurately blocked by the blocking mechanism 3 and the conveying stops, the upper and lower cylinders 42 drive the pressing member 44 to move downward along the upper and lower guide rails 43, pressing the carrier 5 to keep it stable during the conveying process and avoid the carrier 5 from shifting position due to vibration or other factors, thereby achieving precise positioning of the carrier 5.

[0035] It should also be noted that, without conflict, the embodiments of this utility model and the features therein can be combined with each other to obtain new embodiments.
