Description

Technical Field

[0001] This utility model relates to the field of PCB board conveying equipment technology, specifically to a single-rail connecting platform. Background Technology

[0002] In the electronics manufacturing industry, printed circuit boards (PCBs) are key components of electronic products. The automation and efficiency of their production process play a decisive role in product quality and production efficiency. PCBs undergo multiple processes during production, such as surface mount technology (SMT), soldering, and testing. The transfer and connection between these processes are crucial. During production, workers need to work with conveyor belts to inspect the PCBs on the production line to ensure their quality. There are many types of conveyor belts on the market, but most of them have a fixed spacing between the conveyor rails, which can only transport PCBs of the same width and cannot meet the needs of transporting PCBs of different widths.

[0003] Utility model patent CN212291821U discloses a PCB board single-rail connecting platform. Temporary feeding plates and side plates are respectively installed on the front and back edges of the upper end of the frame. Guide rods are installed between the side walls of the temporary feeding plates and side plates. The guide rail body of the conveyor rail is movably sleeved on the outer wall of the guide rod via a slider at the bottom. A cylinder is installed on the outer wall of the side plate near the guide rail body, and a piston push rod connects to the guide rail body. The cylinder controls the extension and retraction of the piston push rod, causing the guide rail body to move on the outer wall of the guide rod, adjusting the distance between the two sets of guide rail bodies. This meets the needs of conveying PCBs of different widths, making it convenient and fast. The back outer wall of the side plate is fixedly connected to the bottom of the support with fixing bolts. A lighting lamp is installed at the lower end of the cross arm at the top of the support, providing a bright environment for workers to check the PCB board production quality in dimly lit workshop conditions, ensuring that workers are not affected by the dim workshop conditions when inspecting PCB boards.

[0004] While this technical solution has the advantage of meeting the needs of conveying PCBs of different widths, most current monorail conveyor systems that can adjust the conveyor size still primarily rely on cylinders to move two tracks closer together or further apart to achieve the spacing adjustment. Furthermore, each track's conveyor belt is driven by a separate motor. This can lead to manufacturing and assembly defects, resulting in inaccurate, synchronized, and stable conveying between the two conveyor belts, affecting the conveying effect. Additionally, using two motors also results in energy consumption. Therefore, we propose a monorail conveyor system. Utility Model Content

[0005] The purpose of this invention is to provide a monorail docking station to address the deficiencies mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A monorail docking station includes a workbench with a top panel fixedly mounted on it. Side panels are fixedly mounted on both the front and rear sides of the top panel. A conveyor rail for conveying PCB boards is provided between the two side panels. The conveyor rail includes two symmetrical cylinders fixedly mounted on the corresponding side panels. A support plate is detachably mounted at the end of the telescopic shaft of each cylinder. A rotating shaft is rotatably connected to both ends of the support plate. A conveyor belt is fitted on each of the two symmetrical rotating shafts. A linkage rod is fixedly mounted at the end of one of the symmetrical rotating shafts, and a rectangular insert rod is fixedly mounted at the end of the other symmetrical rotating shaft. The rectangular insert rod and the linkage rod are interlocked and linked. A servo motor is coaxially mounted at the end of one of the rotating shafts.

[0008] Preferably, a rectangular plate is fixedly installed at the end of the telescopic shaft of the cylinder, and the support plate is detachably installed on the side of the rectangular plate by a plurality of fastening bolts.

[0009] Preferably, two symmetrical guide posts are fixedly installed on the side of the support plate, and two symmetrical guide sleeves are fixedly installed on the inner side of the side plate. The guide posts are located inside the guide sleeves and are slidably connected to the guide sleeves.

[0010] This feature ensures that the support plate moves more stably and smoothly when moving back and forth.

[0011] Preferably, bearings are fixedly installed in the left and right sides of the support plate, and the rotating shaft is fixedly installed on the inner ring of the bearing.

[0012] Preferably, the linkage rod is provided with a rectangular hole at one end that communicates with the outside, and the rectangular insertion rod is located in the rectangular hole and slidably connected to the rectangular hole;

[0013] Preferably, both the rectangular insert and the rectangular hole have rectangular cross-sections, and the dimensions of the rectangular insert are adapted to the dimensions of the rectangular hole;

[0014] These two settings enable stable assembly of the rectangular insert rod and the linkage rod without affecting transmission and spacing adjustment.

[0015] Preferably, the lengths of the rectangular insert and the linkage rod are between 5cm and 10cm, and the servo motor is fixedly installed on the side of the support plate.

[0016] Preferably, two symmetrical guide plates are fixedly installed on the inner side of one of the support plates, and two symmetrical guide storage plates are fixedly installed on the inner side of the other support plate. The guide plates are located inside the guide storage plates and are slidably connected to the guide storage plates.

[0017] This design makes the relative movement between the two support plates more stable.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model, by setting an adjustable conveyor rail, uses a cylinder to drive the support plate to move back and forth, thereby adjusting the distance between the two conveyor belts. This further enables flexible adjustment of the transmission of PCB boards of different specifications. Combined with the sliding structure of the guide post and guide sleeve, it ensures the stability of the support plate movement, can quickly adapt to diverse production needs, and improves the versatility and production efficiency of the production line.

[0020] 2. This utility model achieves stable linkage between the front and rear symmetrical conveyor belts by designing a joint structure between the linkage rod and the rectangular insertion rod, and by setting a guide plate and a guide storage plate on the support plate. This not only ensures the smooth transport of PCB boards, but also guarantees the reliability of the transmission when the conveyor belt spacing needs to be adjusted to accommodate PCB boards of different sizes. This makes the transmission process smoother and effectively improves the accuracy and stability of PCB board transmission. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-4 This utility model provides a technical solution: a single-rail connecting platform, including a workbench 1, on which a top panel 10 is fixedly installed. Side panels 11 are fixedly installed on both the front and rear sides of the top panel 10. A conveyor rail 2 for conveying PCB boards is provided between the two side panels 11. The conveyor rail 2 includes two symmetrical cylinders 20, each fixedly installed on a corresponding side panel 11. A support plate 21 is detachably installed at the end of the telescopic shaft of each cylinder 20. Rotary shafts 25 are rotatably connected to both ends of the support plate 21. Conveyor belts 28 are fitted onto the two symmetrical rotating shafts 25. One of the rotating shafts 25 is fixedly mounted with a linkage rod 26 at one end, and the other rotating shaft 25, which is symmetrically positioned, is fixedly mounted with a rectangular insert rod 27 at one end. The rectangular insert rod 27 and the linkage rod 26 are inserted and linked together. A servo motor 251 is coaxially mounted at one end of one of the rotating shafts 25, ensuring that the servo motor 251 can work to drive the rotating shaft 25 to rotate, which in turn drives the conveyor belt 28 to rotate, thus realizing the PCB board conveying operation. The cylinder 20 can work to drive the support plate 21 to move, thereby adjusting the distance between the two conveyor belts 28 to accommodate PCB boards of different sizes.

[0032] In this embodiment, when the two ends of the PCB board are placed on the conveyor belt 28 for conveying, the position between the two conveyor belts 28 is exposed. At this time, the external detection component installed on the upper panel 10 can perform detection operation on the bottom part of the PCB board placed between the two conveyor belts 28 from bottom to top.

[0033] like Figure 2 As shown, a rectangular plate 201 is fixedly installed at the end of the telescopic shaft of the cylinder 20. The support plate 21 is detachably installed on the side of the rectangular plate 201 by multiple fastening bolts, which facilitates the fixing, installation and disassembly of the support plate 21.

[0034] In this embodiment, two symmetrical guide posts 23 are fixedly installed on the side of the support plate 21, and two symmetrical guide sleeves 22 are fixedly installed on the inner side of the side plate 11. The guide posts 23 are located inside the guide sleeves 22 and are slidably connected to the guide sleeves 22, which ensures that the support plate 21 moves more stably and smoothly when moving back and forth.

[0035] like Figure 3 As shown, bearings 24 are fixedly installed on both sides of the support plate 21, and the rotating shaft 25 is fixedly installed on the inner ring of the bearing 24. This greatly reduces the friction when the rotating shaft 25 rotates, so that the conveyor belt 28 sleeved on the rotating shaft 25 can operate more smoothly and efficiently, providing power guarantee for the stable conveying of PCB boards and reducing equipment operating energy consumption and wear.

[0036] like Figure 4 As shown, the linkage rod 26 has a rectangular hole 261 with its end connected to the outside. A rectangular insert rod 27 is located inside the rectangular hole 261 and is slidably connected to it. Both the rectangular insert rod 27 and the rectangular hole 261 have rectangular cross-sections. The dimensions of the rectangular insert rod 27 and the rectangular hole 261 are matched, enabling stable linkage between the symmetrical conveyor belts 28. This structure not only ensures effective power transmission but also allows for adjustment of the conveyor belt spacing 28 within a certain range to accommodate the transmission of PCBs of different sizes, without affecting the transmission effect, thus enhancing the versatility and flexibility of the docking station.

[0037] Specifically, the lengths of the rectangular insert 27 and the linkage rod 26 are between 5cm and 10cm. The servo motor 251 is fixedly installed on the side of the support plate 21, providing a stable and controllable power source for the operation of the conveyor belt 28.

[0038] It is worth noting that two symmetrical guide plates 3 are fixedly installed on the inner side of one of the support plates 21, and two symmetrical guide storage plates 4 are fixedly installed on the inner side of the other support plate 21. The guide plates 3 are located inside the guide storage plates 4 and are slidably connected to the guide storage plates 4, so that the two support plates 21 can move smoothly along a predetermined direction during relative movement, which further enhances the stability of the conveyor rail 2 structure. This design ensures that the entire conveying system operates smoothly when adjusting the conveyor belt spacing or adapting to the transmission of PCB boards of different specifications, and avoids adverse effects on the transmission of PCB boards due to unstable movement of the support plates.

[0039] Finally, it should be noted that the cylinder 20 and servo motor 251 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0040] When using the monorail connecting platform of this utility model, firstly, according to the size of the PCB board to be conveyed, start the cylinder 20, whose telescopic shaft drives the support plate 21 to move, so that the guide column 23 slides in the guide sleeve 22, ensuring that the distance between the two conveyor belts 28 is adjusted smoothly to adapt to the width of the PCB board.

[0041] Next, the servo motor 251 is started, which drives the coaxial rotating shaft 25 to rotate. Due to the insertion and cooperation of the rectangular plug rod 27 and the linkage rod 26, the front and rear symmetrical conveyor belts 28 operate synchronously, realizing the smooth transport of the PCB board on the conveyor rail 2. During this process, the guide plate 3 slides in the guide storage plate 4, which further enhances the stability of the conveyor rail 2 structure and ensures that the PCB board does not deviate during transmission.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
