[0002] In the electronics manufacturing industry, especially when it comes to the production process of PCB circuit boards, efficient and lossless transmission technology is the key. Traditional PCB circuit board transmission methods, especially when it is necessary to transfer the circuit board from one height to another transmission mechanism at a different height, usually rely on complex robotic arms or other mechanical structures. However, these methods not only increase the complexity and cost of the equipment, but may also lead to a decrease in production efficiency due to delays, errors or instability in mechanical movements, and may even damage sensitive circuit boards. Therefore, the market is in urgent need of a simple, efficient and low-cost device to achieve lossless and stable transfer of PCB circuit boards between transmission mechanisms at different heights. Summary of the invention

[0003] In order to solve the above problems, the present invention proposes a simple, efficient and low-cost device to achieve lossless and stable transfer of PCB circuit boards from a low-level transmission mechanism to a high-level transmission mechanism.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: a PCB circuit board processing device, used to transfer the PCB circuit board from a low-level transmission mechanism to a high-level transmission mechanism, comprising a transfer shaft arranged between the low-level transmission mechanism and the high-level transmission mechanism, the transfer shaft is located at the end of the low-level transmission mechanism and the starting point of the high-level transmission mechanism, the transfer shaft is externally connected to a driving mechanism for driving its self-rotation, the rotation tangent direction of the transfer shaft is consistent with the transmission direction of the PCB circuit board, the outer surface of the transfer shaft is arranged in a circular array with a plurality of positioning blades, the setting direction of each positioning blade is consistent with the radial direction of the transfer shaft, and the spacing between adjacent positioning blades is adapted to the thickness of the PCB circuit board;

[0005] It also includes a central axis mounted at the starting point of the high-position transmission mechanism through multiple mounting seats, the central axis is externally connected to a driving mechanism for driving its rotation, the rotation tangent direction of the central axis is consistent with the transmission direction of the PCB circuit board, and multiple annular flexible sheets are coaxially arranged on the central axis, and the height of each flexible sheet is higher than the transmission surface of the high-position transmission mechanism.

[0006] In some embodiments, the low-position transmission mechanism and the high-position transmission mechanism are specifically roller-type transmission mechanisms, each of which includes a plurality of rollers arranged at equal intervals, and the outer surfaces of the rollers are covered with anti-slip material.

[0007] In some embodiments, the distance between two adjacent positioning blades is narrower the closer they are to the transfer axis, and is wider the farther they are from the transfer axis.

[0008] In some embodiments, the central shaft is hinged to the high-position transmission mechanism with the aid of a mounting seat damping.

[0009] In some embodiments, the flexible sheet is made of elastic polymer material.

[0010] In some embodiments, both sides of the flexible sheet are provided with a plurality of grooves arranged in a circular array, and the length direction of each groove is consistent with the radial direction of the flexible sheet.

[0011] A PCB circuit board processing method, based on the above-mentioned PCB circuit board processing device, comprises the following steps:

[0012] a. Preparation stage: Ensure that the low-level transmission mechanism and the high-level transmission mechanism are in normal working condition, check whether the driving mechanism of the transfer shaft and the central shaft is operating normally, and whether the positioning blades and flexible sheets are intact and installed correctly;

[0013] b. Transmission and positioning: Start the low-position transmission mechanism to transmit the PCB to its final position; during the transmission process, one side of the PCB will be accurately inserted between two adjacent positioning blades to achieve precise positioning;

[0014] c. Flipping and guiding: As the transfer shaft rotates, the PCB inserted between two adjacent positioning blades will be driven to flip toward the high-position transmission mechanism; at the same time, the central shaft also starts to rotate, ready to receive the flipped circuit board;

[0015] d. Contact and flattening: The flipped PCB will first contact each flexible sheet and flatten each flexible sheet it contacts. During this process, the flexible sheet can absorb the impact force and protect the circuit board from damage.

[0016] e. Driving and transmitting: Under the action of friction, the flattened flexible sheet stably drives the PCB circuit board to the starting point of the high-position transmission mechanism; then, the circuit board continues to be transmitted backward on the transmission surface of the high-position transmission mechanism;

[0017] f. Repeat operation: Repeat the above steps b to e to achieve a continuous and efficient PCB circuit board processing process;

[0018] g. Maintenance and inspection: Regularly maintain and inspect the processing equipment to ensure that all components are in good working condition and replace worn or damaged positioning blades and flexible sheets in a timely manner.

[0019] In some embodiments, in step c, the rotation speed of the central shaft is first adjusted to be greater than the transmission speed of the PCB circuit board on the low-position transmission mechanism, and then adjusted to match the transmission speed of the PCB circuit board on the high-position transmission mechanism.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The invention realizes accurate positioning and stable transmission of PCB circuit boards from a low-position transmission mechanism to a high-position transmission mechanism through the ingenious design of the transfer shaft and the positioning blades. This design simplifies the positioning process of the circuit board, improves the transmission accuracy, effectively prevents the circuit board from shaking or deflecting during the transmission process, and ensures the stability of the transmission.

[0022] Secondly, the introduction of the flexible sheet provides a buffering effect for the circuit board. When the circuit board flips over and contacts the flexible sheet, the flexible sheet can absorb the impact force and prevent the circuit board from being damaged by directly hitting hard objects. At the same time, the flexible sheet can be flattened to increase the contact area with the PCB circuit board, thereby increasing the friction force and ensuring that the circuit board can be stably driven to the high-position transmission mechanism and continue to be transmitted backward. This design not only enhances the stability of the circuit board during the transmission process, but also improves the accuracy and reliability of the transmission.

[0023] In addition, the technical solution of the present invention also focuses on reducing mechanical damage and improving production efficiency. The material and design of the positioning blade can take into account the protection of the circuit board, avoiding scratches or collisions that may be caused by traditional transfer methods such as mechanical arms. At the same time, the rotation of the operating shaft and the central shaft is consistent with the transmission direction of the PCB circuit board, so that the circuit board can be continuously and smoothly driven to flip to the high-position transmission mechanism without manual intervention, greatly improving production efficiency.

[0024] In summary, the technical solution of the present invention brings significant advantages to the production and processing of PCB circuit boards through the beneficial effects of precise positioning and stable transmission, buffering and protection, reduction of mechanical damage and improvement of production efficiency. It not only improves product quality and production efficiency, but also reduces production costs and maintenance difficulty. It has broad application prospects and important market value.

[0036] like Figure 1-6 As shown, this embodiment provides a PCB circuit board processing device, which is used to transfer a PCB circuit board 100 from a low-level transmission mechanism 1 to a high-level transmission mechanism 2, and includes a transfer shaft 3 arranged between the low-level transmission mechanism 1 and the high-level transmission mechanism 2, the transfer shaft 3 is located at the end point of the low-level transmission mechanism 1 and the starting point of the high-level transmission mechanism 2, the transfer shaft 3 is externally connected to a driving mechanism for driving its rotation, the rotation tangential direction of the transfer shaft 3 is consistent with the transmission direction of the PCB circuit board 100, and the outer surface of the transfer shaft 3 is arranged in a circular array with a plurality of positioning blades 4, and the setting direction of each positioning blade 4 is consistent with the radial direction of the transfer shaft 3. The positioning blades 4 are arranged in a circular array on the operating shaft, which ensures that the PCB circuit board 100 can be accurately inserted between adjacent blades when it is transmitted to the end point. This design not only simplifies the positioning process of the circuit board, but also improves the transmission accuracy. The spacing between adjacent positioning blades 4 is adapted to the thickness of the PCB circuit board 100, which effectively prevents the circuit board from shaking or deflecting during the transmission process, and ensures the stability of the transmission. When the PCB circuit board 100 on the low-level transmission mechanism 1 is transmitted to the end point, one side of the PCB circuit board 100 will be inserted between any two adjacent positioning blades 4, and then with the rotation of the central shaft 6, the PCB circuit board 100 inserted between the two adjacent positioning blades 4 will be driven to flip toward the high-level transmission mechanism 2. When the PCB circuit board 100 contacts the transmission surface of the high-level transmission mechanism 2, the PCB circuit board 100 will be removed from between the two adjacent positioning blades 4 and continue to be transmitted backward from the starting point of the high-level transmission mechanism 2;

[0037] It also includes a central axis 6 mounted at the starting point of the high-level transmission mechanism 2 through multiple mounting seats 5. The central axis 6 is externally connected to a driving mechanism for driving its rotation. The rotation tangent direction of the central axis 6 is consistent with the transmission direction of the PCB circuit board 100. A plurality of annular flexible sheets 7 are coaxially arranged on the central axis 6. The height of each flexible sheet 7 is higher than the transmission surface of the high-level transmission mechanism 2. The height design of the flexible sheet 7 enables the circuit board to be smoothly guided to the high-level transmission mechanism 2 when in contact, thereby avoiding the risk of falling due to the height difference. When the PCB circuit board 100 inserted between two adjacent positioning blades 4 is driven to flip toward the high-level transmission mechanism 2, the flipped PCB circuit board 100 will first contact with each flexible sheet 7 and flatten each flexible sheet 7 it contacts. As the central axis 6 rotates, under the action of friction, the PCB circuit board 100 is brought to the starting point of the high-level transmission mechanism 2. When the PCB circuit board 100 flips over and contacts with the flexible sheets 7, due to the material and design of the flexible sheets 7, they can be flattened by the circuit board. This process increases the contact area between the flexible sheet 7 and the circuit board, so that more of the flexible sheet 7 surface fits tightly with the circuit board, and the increase in contact area directly leads to an increase in friction. A larger contact area means more intermolecular interactions, thereby enhancing the friction between the flexible sheet 7 and the circuit board. This enhanced friction is crucial to ensure that the circuit board can be stably driven to the high-position transmission mechanism 2 during the flipping process. And by increasing the contact area and friction, the design of the flexible sheet 7 effectively improves the stability of the circuit board during the transmission process. Even if there is a certain weight or size difference in the circuit board, the flexible sheet 7 can ensure the smooth transmission of the circuit board through its good fit and friction. In addition, the design of the flexible sheet 7 also provides a buffering effect for the PCB circuit board 100. When the circuit board flips and contacts the flexible sheet 7, the flexible sheet 7 can absorb the impact force to prevent the circuit board from being damaged by directly hitting hard objects.

[0038] This PCB circuit board processing device realizes accurate positioning and stable transmission of the PCB circuit board 100 from the low-position transmission mechanism 1 to the high-position transmission mechanism 2 through the ingenious design of the transfer shaft 3 and the positioning blade 4. This design not only simplifies the positioning process of the circuit board and improves the transmission accuracy, but also effectively prevents the circuit board from shaking or deflecting during the transmission process, thereby ensuring the stability of the transmission.

[0039] Secondly, the introduction of the flexible sheet 7 provides a buffering effect for the circuit board. When the circuit board flips and contacts the flexible sheet 7, the flexible sheet 7 can absorb the impact force and prevent the circuit board from being damaged by directly hitting a hard object. At the same time, the flexible sheet 7 can be flattened to increase the contact area with the PCB circuit board 100, thereby increasing the friction force and ensuring that the circuit board can be stably driven to the high-position transmission mechanism 2 and continue to be transmitted backward. This design not only enhances the stability of the circuit board during the transmission process, but also improves the accuracy and reliability of the transmission.

[0040] In addition, the technical solution of the present invention also focuses on reducing mechanical damage and improving production efficiency. The material and design of the positioning blade 4 can take into account the protection of the circuit board, avoiding scratches or collisions that may be caused by traditional transfer methods such as mechanical arms. At the same time, the rotation of the operating shaft and the central shaft 6 is consistent with the transmission direction of the PCB circuit board 100, so that the circuit board can be continuously and smoothly driven to flip to the high-level transmission mechanism 2 without manual intervention, greatly improving production efficiency.

[0041] In summary, the technical solution of the present invention brings significant advantages to the production and processing of the PCB circuit board 100 through the beneficial effects of precise positioning and stable transmission, buffering and protection, reduction of mechanical damage and improvement of production efficiency.

[0042] In some embodiments, Figure 1 As shown, the low-position transmission mechanism 1 and the high-position transmission mechanism 2 are specifically roller-type transmission mechanisms, each of which includes a plurality of rollers arranged at equal intervals, and the outer surface of the roller is covered with anti-skid material to ensure the stability of the PCB circuit board 100 during the transmission process. The design of the roller-type transmission mechanism enables the PCB circuit board 100 to slide smoothly on its surface and be smoothly transmitted from the end point of the low-position transmission mechanism 1 to the starting point of the high-position transmission mechanism 2. This roller-type transmission mechanism is not only simple in structure and easy to maintain, but also can effectively reduce friction and resistance during the transmission process, further protecting the PCB circuit board 100 from damage. At the same time, the cooperation of the roller-type transmission mechanism with the transfer shaft 3 and the central shaft 6 realizes the continuous and smooth transfer of the PCB circuit board 100 from the low position to the high position without manual intervention, further improving the production efficiency.

[0043] In some embodiments, Figure 2-3As shown, the spacing between two adjacent positioning blades 4 is narrower the closer to the transfer shaft 3, and wider the farther away from the transfer shaft 3. This design enables the PCB circuit board 100 to be gradually guided and firmly inserted between the adjacent positioning blades 4 during the rotation of the transfer shaft 3, ensuring the stability and accuracy of the circuit board during the transmission process. Specifically, when the PCB circuit board 100 is transmitted from the low-level transmission mechanism 1 to the transfer shaft 3, due to the gradual decrease in the spacing between the adjacent positioning blades 4, the circuit board will be gradually guided and inserted between the adjacent positioning blades 4, achieving the precise positioning of the circuit board. At the same time, this design can also adapt to PCB circuit boards 100 of different widths, improving the versatility and flexibility of the device. In the process of the transfer shaft 3 driving the circuit board to flip to the high-level transmission mechanism 2, due to the gradual increase in the spacing between the adjacent positioning blades 4, the circuit board can be more smoothly moved out from between the positioning blades 4, and smoothly docked with the high-level transmission mechanism 2, achieving lossless and stable transfer of the circuit board. In summary, the spacing design between two adjacent positioning blades 4 not only improves the transmission accuracy and stability of the circuit board, but also enhances the versatility and flexibility of the device, providing a strong guarantee for the efficient and stable transfer of the PCB circuit board 100.

[0044] In some embodiments, the central shaft 6 is damped and hinged on the high-position transmission mechanism 2 by means of the mounting base 5. This damped hinge design allows the central shaft 6 to be adjusted in height and position within a certain range to meet the transmission requirements of PCB circuit boards 100 of different heights and angles.

[0045] In some embodiments, the flexible sheet 7 is made of an elastic polymer material and has excellent flexibility and wear resistance. The selection of this material allows the flexible sheet 7 to be elastically deformed when it is pressed by the PCB circuit board 100, so that it fits tightly with the surface of the circuit board, increases the contact area and improves the friction, and ensures that the circuit board can be stably driven to the high-position transmission mechanism 2 during the flipping process. At the same time, the wear resistance of the elastic polymer material makes the flexible sheet 7 not easy to wear during long-term use, maintains good fit and friction, and extends the service life of the device. In addition, this material also has good impact resistance. When the circuit board flips and contacts the flexible sheet 7, the flexible sheet 7 can absorb the impact force and further protect the circuit board from damage. In summary, the flexible sheet 7 is made of an elastic polymer material, which not only improves the stability and accuracy of the circuit board transmission, but also extends the service life of the device and provides effective buffering and protection for the circuit board.

[0046] In some embodiments, Figure 6As shown, both sides of the flexible sheet 7 are arranged in a circular array with a number of grooves 701, and the length direction of each groove 701 is consistent with the radial direction of the flexible sheet 7. This design enables the grooves 701 to provide additional space to accommodate the tiny protrusions or uneven parts that may exist on the surface of the circuit board when the flexible sheet 7 contacts the PCB circuit board 100, thereby ensuring a tight fit between the flexible sheet 7 and the circuit board. More importantly, since the length direction of each groove 701 is consistent with the radial direction of the flexible sheet 7, when the flexible sheet 7 is flattened, its length direction will intersect with the transmission path of the PCB circuit board 100. This cross design can significantly increase the friction between the flexible sheet 7 and the PCB circuit board 100, and effectively avoid slipping between the two during the transmission process. The enhanced friction ensures that the circuit board can be more stably driven to the high-position transmission mechanism 2 during the flipping process, thereby improving the accuracy and reliability of the transmission. In summary, the design of providing grooves 701 on both sides of the flexible sheet 7 not only improves the stability of circuit board transmission, but also effectively avoids slipping by enhancing friction, thereby providing a strong guarantee for efficient and lossless transfer of the PCB circuit board 100.

[0047] This embodiment also provides a PCB circuit board processing method. Figure 1-5 The method is based on the PCB circuit board processing device in any of the above embodiments, and comprises the following steps:

[0048] a. Preparation stage: Ensure that the low-level transmission mechanism 1 and the high-level transmission mechanism 2 are in normal working condition, check whether the driving mechanisms of the transfer shaft 3 and the central shaft 6 are operating normally, and whether the positioning blades 4 and the flexible sheet 7 are intact and installed correctly.

[0049] b. Transmission and positioning: Start the low-position transmission mechanism 1 to transmit the PCB circuit board 100 to its final position. During the transmission process, one side of the PCB circuit board 100 will be accurately inserted between two adjacent positioning blades 4 to achieve precise positioning.

[0050] c. Flipping and guiding: As the transfer shaft 3 rotates, the PCB circuit board 100 inserted between two adjacent positioning blades 4 will be driven to flip toward the high-position transmission mechanism 2. At the same time, the central shaft 6 also starts to rotate, ready to receive the flipped circuit board.

[0051] d. Contact and flattening: The flipped PCB circuit board 100 will first contact each flexible sheet 7 and flatten each flexible sheet 7 it contacts. In this process, the flexible sheet 7 can absorb the impact force and protect the circuit board from damage.

[0052] e. Driving and transporting: Under the action of friction, the flattened flexible sheet 7 stably drives the PCB circuit board 100 to the starting point of the high-level transport mechanism 2. Then, the circuit board continues to be transported backward on the transport surface of the high-level transport mechanism 2.

[0053] f. Repeat operation: Repeat the above steps b to e to achieve a continuous and efficient PCB circuit board 100 processing process.

[0054] g. Maintenance and inspection: Regularly maintain and inspect the processing device to ensure that all components are in good working condition and replace worn or damaged positioning blades 4 and flexible sheets 7 in a timely manner.

[0055] Through this method, the advantages of the PCB circuit board processing device of claim 1 can be fully utilized to achieve lossless and stable transfer of the PCB circuit board 100 from the low-level transmission mechanism 1 to the high-level transmission mechanism 2, thereby improving production efficiency and reducing the risk of mechanical damage.

[0056] In some embodiments, in step c, the rotation speed of the central shaft 6 is first adjusted to be greater than the transmission speed of the PCB circuit board 100 on the low-position transmission mechanism 1 to ensure that the circuit board can be smoothly driven to the high-position transmission mechanism 2, and then adjusted to match the transmission speed of the PCB circuit board 100 on the high-position transmission mechanism 2 to achieve a stable and continuous transmission process.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
