Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to an FPC board feeding mechanism. Background Technology

[0002] As electronic devices continue to evolve towards miniaturization, lightweighting, and high performance, flexible printed circuit boards (FPCs) are increasingly widely used in numerous fields such as smartphones, tablets, and wearable devices. In the FPC manufacturing process, the material feeding stage is a crucial initial step in the entire production line, and its efficiency and precision directly affect subsequent processing steps and the quality of the final product.

[0003] Traditional FPC feeding methods often rely on manual operation or simple mechanical structures. Manual feeding is not only labor-intensive and inefficient, but it is also difficult to guarantee the accuracy and consistency of the feeding position each time. This can easily lead to deviations, offsets, or even damage to the FPC during subsequent processing, seriously affecting the product yield and production efficiency.

[0004] While some simple mechanical feeding structures alleviate the burden on manual labor to some extent, they still have many shortcomings. For example, in terms of positioning, simple mechanical blocks or grooves are usually used. This positioning method has limited accuracy for thin and easily deformable materials like FPCs and cannot meet the requirements of high-precision production. At the same time, it is difficult to achieve automated control of the tray lifting during the feeding process, making the feeding operation less smooth and prone to friction or collision between the FPC and other components.

[0005] Furthermore, with the continuous improvement of industrial automation, the requirements for the intelligence and integration of production equipment are also increasing. Traditional feeding mechanisms lack effective connection and information exchange capabilities with other production links, making it difficult to integrate into the fully automated production line control system, thus limiting the collaborative work efficiency and intelligent management level of the entire production system.

[0006] Therefore, it is necessary to propose an improved technical solution to address the above problems. Utility Model Content

[0007] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0008] An FPC board feeding mechanism includes a base plate, a feeding assembly mounted on the upper surface of the base plate, and a lifting assembly mounted on the lower surface of the base plate.

[0009] The feeding assembly includes a feeding fixed plate fixedly connected to the base plate, a feeding movable plate movably connected above the feeding fixed plate, and a plurality of positioning posts slidably fitted between the feeding fixed plate and the feeding movable plate. The upper ends of the plurality of positioning posts protrude through the feeding movable plate to form a positioning groove acting on the product. Photoelectric fixed plates are installed on both sides of the feeding fixed plate and the feeding movable plate, and a photoelectric sensor is installed on the top of the photoelectric fixed plate.

[0010] The lifting assembly includes a power component and a transmission movable plate connected to the output end of the power component. Several push rods are installed on the transmission movable plate. The push rods pass through the base plate and the material feeding fixed plate in sequence and are fixedly connected to the material feeding movable plate. Driven by the power component, the transmission movable plate and the material feeding movable plate move vertically and linearly relative to the material feeding fixed plate.

[0011] As a further embodiment of this utility model: the lifting assembly further includes a first fixing plate fixedly connected to the base plate, and a second fixing plate fixedly connected below the first fixing plate via a guide rod. The transmission movable plate is located between the first fixing plate and the second fixing plate and is slidably connected to the guide rod. The second fixing plate is also used to install the power component.

[0012] As a further embodiment of this utility model: the power component includes a motor and a lead screw transmission assembly that is synchronously connected to the motor. The lead screw transmission assembly has a bearing seat mounted on a second fixed plate, a bearing mounted on a first fixed plate, a lead screw connected between the bearing seat and the bearing, and a slider that rotates with the lead screw. The slider is fixedly connected to a transmission movable plate.

[0016] As a further embodiment of this utility model: the T-shaped slider is interference-fitted with the first groove.

[0017] As a further embodiment of this utility model: the top height of the photoelectric fixing plate is lower than the top height of the positioning post.

[0018] As a further embodiment of this utility model: the side of the feeding fixing plate is provided with a mounting hole, and the lower end of the photoelectric fixing plate is provided with an elongated hole adapted to the mounting hole.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1) Through the structural design of positioning posts and positioning slots, precise planar positioning of FPC products can be achieved, effectively preventing horizontal offset and shaking of products during the feeding process. After the FPC product is placed into the positioning slot, its edge can fit the positioning post, effectively limiting the translation and rotation freedom of the product on the horizontal plane, and avoiding processing deviations caused by inaccurate positioning.

[0021] 2) By leveraging the linkage mechanism between photoelectric sensors and lifting components, the vertical height of FPC products can be precisely controlled, ensuring they remain at the photoelectric sensing position. This provides a highly accurate and stable material supply foundation for subsequent operations on the automated production line (such as gripping, handling, and processing), greatly improving positioning accuracy and material handling consistency during production, and contributing to improved overall product quality and production efficiency.

[0022] 3) It not only reduces manual intervention, lowers labor costs and intensity, but also effectively avoids various problems caused by human error or limitations of traditional mechanical structures, such as product damage and production interruption. In addition, the excellent automation and intelligence of this feeding mechanism allows it to be easily integrated into complex fully automated production line systems, enhancing the smoothness of connection and information exchange efficiency between various links of the production line. This is conducive to improving the intelligent management level and collaborative work efficiency of the entire production system, adapting to the requirements of modern manufacturing for efficient and intelligent production models, and enhancing the competitiveness of enterprises in the market.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0033] Please see Figure 1-5 In this embodiment of the utility model, an FPC board feeding mechanism includes a base plate 1, a feeding component 2 installed on the upper surface of the base plate 1, and a lifting component 3 installed on the lower surface of the base plate 1.

[0034] The feeding assembly 2 includes a feeding fixed plate 4 fixedly connected to the base plate 1, a feeding movable plate 5 movably connected above the feeding fixed plate 4, and a plurality of positioning posts 6 slidably fitted between the feeding fixed plate 4 and the feeding movable plate 5. The upper ends of the plurality of positioning posts 6 protrude through the feeding movable plate 5 to form a positioning groove 7 acting on the product. Photoelectric fixed plates 8 are installed on both sides of the feeding fixed plate 4 and the feeding movable plate 5, and a photoelectric sensor 9 is installed on the top of the photoelectric fixed plate 8.

[0035] The lifting assembly 3 includes a power component 10 and a transmission movable plate 11 connected to the output end of the power component 10. Several push rods 12 are installed on the transmission movable plate 11. The push rods 12 pass through the base plate 1 and the material feeding fixed plate 4 in sequence and are fixedly connected to the material feeding movable plate 5. Driven by the power component 10, the transmission movable plate 11 and the material feeding movable plate 5 are driven to move in a vertical direction relative to the material feeding fixed plate 4.

[0036] In the technical solution of this utility model:

[0037] The feeding fixing plate 4 is firmly fixed to the base plate 1, providing a basic support structure for the entire feeding assembly 2. The feeding movable plate 5 is located above the feeding fixing plate 4 and forms a movable connection with it. This movable connection allows the feeding movable plate 5 to move relative to the base plate within a certain range to realize the lifting function of the material tray. There are several positioning columns 6, which are slidably fitted between the feeding fixing plate 4 and the feeding movable plate 5. The upper end of the positioning column 6 protrudes from the feeding movable plate 5, and together with the feeding movable plate 5, they form a positioning groove 7. The shape and size of the positioning groove 7 can be adapted to the FPC product by adjusting the position of the positioning column 6. When the FPC product is placed in the positioning groove 7, the positioning column 6 supports the product from all sides. Limiting is implemented to prevent horizontal displacement. The positioning post 6 can be designed as a cylinder with a smooth surface, allowing it to slide smoothly in the corresponding holes of the feeding fixed plate 4 and the feeding movable plate 5, ensuring positioning accuracy and stability. The photoelectric fixed plate 8 is installed on both sides of the feeding fixed plate 4 and the feeding movable plate 5, and a photoelectric sensor 9 is installed at its top. The position and angle of the photoelectric sensor 9 are precisely adjusted so that it can accurately sense the topmost FPC product. The photoelectric sensor 9 usually adopts the principle of infrared emission and reception. When an FPC product blocks the infrared light path, the photoelectric sensor 9 will generate a corresponding signal change to determine the presence and position of the product.

[0038] The power unit 10 is the power source for the lifting assembly 3. Common devices include a motor 16, a cylinder, etc. The motor 16 outputs power through rotational motion, which can then be converted into linear motion through a transmission mechanism such as a lead screw and nut pair. The cylinder directly generates the driving force for linear motion through the pressure of gas. The transmission movable plate 11 is connected to the output end of the power unit 10. It plays the role of transmitting power and supporting the push rod 12. For example, in the lead screw and nut pair driven by the motor 16, the transmission movable plate 11 can be fixedly connected to the nut and move with the linear motion of the nut. Several push rods 12 are installed on the transmission movable plate 11. The push rods 12 pass through the base plate 1 and the material feeding fixed plate 4 in sequence and are fixedly connected to the material feeding movable plate 5. The push rods 12 have sufficient strength and rigidity to ensure that they do not bend or deform during the process of pushing the material feeding movable plate 5 up and down.

[0039] Its working principle is as follows: In the initial state, the feeding movable plate 5 is in a lower position, and the FPC product is placed in the positioning slot 7. The photoelectric sensor 9 senses the top FPC product. When the picking equipment on the production line removes the top FPC product, the photoelectric sensor 9 detects the product's disappearance and transmits a signal to the control system. After receiving the signal, the control system starts the power component 10. The power component 10 starts working, such as the motor 16 starting to rotate and drive the lead screw nut pair to move, or the cylinder starting to inflate and push the piston to move, thereby driving the transmission movable plate 11 to move vertically. Since the push rod 12 is fixedly connected to the feeding movable plate 5, the movement of the transmission movable plate 11 will be transmitted to the feeding movable plate 5, causing it to move upward in a straight line relative to the feeding fixed plate 4, thereby lifting the next layer of FPC products placed in the positioning slot 7 to the sensing position of the photoelectric sensor 9. This ensures that the FPC product is at the appropriate height each time it is picked up, which facilitates the automatic picking equipment to perform precise gripping operations and ensures the continuity and efficiency of the entire feeding and picking process.

[0040] In summary, the structural design of the positioning column 6 and positioning groove 7 enables precise planar positioning of the FPC product, effectively preventing horizontal offset and swaying during material feeding. After the FPC product is placed in the positioning groove 7, its edges fit snugly against the positioning column 6, effectively limiting the product's translational and rotational freedom on the horizontal plane and avoiding processing deviations caused by inaccurate positioning. Simultaneously, the linkage mechanism between the photoelectric sensor 9 and the lifting assembly 3 allows for precise control of the FPC product's vertical height, ensuring it remains at the photoelectric sensing position. This provides a highly accurate and stable material supply foundation for subsequent operations on the automated production line (such as gripping, handling, and processing), significantly improving efficiency. The high positioning accuracy and consistent material handling during the production process help improve the overall product quality and production efficiency. Furthermore, it not only reduces manual intervention, lowering labor costs and intensity, but also effectively avoids various problems caused by human error or limitations of traditional mechanical structures, such as product damage and production interruptions. In addition, the excellent automation and intelligence of this feeding mechanism allows it to easily integrate into complex fully automated production line systems, enhancing the smoothness of connections and information exchange efficiency between different stages of the production line. This is conducive to improving the intelligent management level and collaborative work efficiency of the entire production system, adapting to the requirements of modern manufacturing for efficient and intelligent production models, and enhancing the company's competitiveness in the market.

[0041] In this embodiment of the present invention, the lifting assembly 3 further includes a first fixing plate 13 fixedly connected to the base plate 1, and a second fixing plate 15 fixedly connected below the first fixing plate 13 via a guide rod 14. The transmission movable plate 11 is located between the first fixing plate 13 and the second fixing plate 15 and is slidably connected to the guide rod 14. The second fixing plate 15 is also used to install the power component 10.

[0042] The first fixed plate 13 is firmly fixed to the base plate 1, providing support and positioning reference for the upper structure of the entire lifting assembly 3. The second fixed plate 15 is fixedly connected to the first fixed plate 13 via the guide rod 14 and is located below the first fixed plate 13. The second fixed plate 15 is used to install the power component 10. This layout makes the installation position of the power component 10 relatively stable and reasonable, which is conducive to the effective transmission of power. The guide rod 14 not only connects the first fixed plate 13 and the second fixed plate 15, but also provides a sliding guide track for the transmission movable plate 11. The transmission movable plate 11 is located between the first fixed plate 13 and the second fixed plate 15 and is slidably connected to the guide rod 14, ensuring that the transmission movable plate 11 can only move in a straight line in the vertical direction along the guide rod 14 under the drive of the power component 10. For example, the guide rod 14 can be a smooth cylinder. A linear bearing 21 or a sliding sleeve is provided on the movable plate 11 to allow the transmission movable plate 11 to slide smoothly up and down along the guide rod 14, avoiding instability such as offset or shaking during the movement of the transmission movable plate 11. This ensures that the push rod 12 connected to the transmission movable plate 11 can accurately push the material feeding movable plate 5 to move up and down. The power component 10 (such as a motor 16 or a cylinder) is installed on the second fixed plate 15, and its output end is connected to the transmission movable plate 11. When the power component 10 works, the driving force generated acts on the transmission movable plate 11, causing it to move vertically along the guide rod 14. For example, if it is driven by the motor 16, the rotational movement of the output shaft of the motor 16 may be converted into the linear movement of the transmission movable plate 11 through the screw nut mechanism. If it is driven by the cylinder, the piston extension and retraction of the cylinder directly drives the transmission movable plate 11 to move linearly.

[0043] In this embodiment of the present invention, the power component 10 includes a motor 16 and a lead screw 19 transmission assembly that is synchronously belt-connected to the motor 16. The lead screw 19 transmission assembly has a bearing seat 17 mounted on a second fixed plate 15, a bearing 18 mounted on a first fixed plate 13, a lead screw 19 connected between the bearing seat 17 and the bearing 18, and a slider 20 that rotatably engages with the lead screw 19. The slider 20 is fixedly connected to the transmission movable plate 11.

[0044] The motor 16 serves as the power source, transmitting power to the lead screw 19 transmission assembly via a synchronous belt drive. The synchronous belt drive offers advantages such as high transmission efficiency, smooth transmission, shock absorption, and long-distance transmission capability. It effectively and stably transmits the rotational power of the motor 16 to the lead screw 19. The lead screw 19 is mounted between the bearing housing 17 and the bearing 18. The bearing housing 17 is fixed to the second fixed plate 15, and the bearing 18 is mounted on the first fixed plate 13. This layout provides stable support and a rotational foundation for the lead screw 19, ensuring the accuracy and stability of its axial reciprocating motion during rotation. When the lead screw 19 rotates under the drive of the motor 16, the slider 20, which rotates in conjunction with it, moves linearly along the axial direction of the lead screw 19. Since the slider 20 is fixedly connected to the transmission movable plate 11, it drives the transmission movable plate 11 to move vertically along the guide rod 14, ultimately achieving the lifting and lowering drive of the material feeding movable plate 5.

[0045] Among them, the synchronous belt is a transmission belt with equidistant teeth. Synchronous pulleys are installed on the motor shaft 16 and the lead screw shaft 19 respectively. When the motor 16 rotates, the lead screw shaft 19 is driven to rotate synchronously through the meshing action of the synchronous belt.

[0046] In this embodiment of the utility model, the transmission movable plate 11 is provided with a mounting groove that cooperates with the guide rod 14, and a linear bearing 21 that acts on the guide rod 14 is provided at the mounting groove.

[0047] The mounting groove on the transmission movable plate 11 is for cooperation with the guide rod 14. This cooperation allows the transmission movable plate 11 to make directional linear movements along the guide rod 14. A linear bearing 21 is installed in the mounting groove. The inner ring of the linear bearing 21 contacts the guide rod 14. The linear bearing 21 is a rolling bearing 18 specifically designed for guiding linear motion. Its working principle is to convert sliding friction into rolling friction through internal rolling elements (such as balls or rollers). When the transmission movable plate 11 moves along the guide rod 14 under the drive of the power component 10, the rolling elements of the linear bearing 21 roll on the surface of the guide rod 14, making the movement of the transmission movable plate 11 smoother and more stable.

[0048] In this embodiment of the utility model, the material feeding fixing plate 4 and the material feeding movable plate 5 are respectively provided with a first sliding groove 22 and a second sliding groove 23 that act on the positioning column 6, and the first sliding groove 22 and the second sliding groove 23 correspond to each other.

[0049] The lower end of the positioning post 6 is connected to a T-shaped slider 24, which can slide into the first groove 22. The lower end face of the feeding fixing plate 4 is fixedly connected to a third fixing plate 25, which is used to fit the T-shaped slider 24 into the first groove 22.

[0050] The first groove 22 on the feeding fixed plate 4 and the second groove 23 on the feeding movable plate 5 correspond to each other. The T-shaped slider 24 at the lower end of the positioning column 6 can first be fitted into the first groove 22 with the assistance of the third fixed plate 25, and then slide between the first groove 22 and the second groove 23. This structural design allows the positioning column 6 to slide stably between the feeding fixed plate 4 and the feeding movable plate 5, and is effectively constrained in the horizontal direction. When the feeding movable plate 5 moves up and down relative to the feeding fixed plate 4, the positioning column 6 can maintain a vertical state and a relatively fixed position, thereby ensuring that the shape and size of the positioning groove 7 formed with the feeding movable plate 5 are stable, and playing a precise positioning role for the FPC product.

[0051] Since the positioning column 6 can slide within the first slide groove 22 / second slide groove 23, by adjusting the position of the positioning column 6 within the slide groove, it can adapt to FPC products of different sizes within a certain range. When different specifications of FPC products need to be switched on the production line, it is only necessary to simply adjust the spacing of the positioning column 6, without replacing the entire feeding assembly 2, which improves the versatility and flexibility of the feeding mechanism and reduces production costs.

[0052] In this embodiment of the present invention, the T-shaped slider 24 is interference-fitted with the first groove 22.

[0053] An interference fit refers to a mechanical assembly where the actual size of the shaft (here, the T-slider 24 is equivalent to the shaft) is slightly larger than the actual size of the hole (the first groove 22). A certain assembly force is used to tightly connect the two. In this case, there is a certain pressure between the T-slider 24 and the first groove 22, so that the T-slider 24 is tightly "pressed" into the first groove 22. When the positioning post 6 is subjected to external forces in the vertical direction (such as the force generated by the lifting and lowering of the feeding movable plate 5) or the horizontal direction (such as the slight collision force generated during the placement of the FPC board), the friction and clamping force generated by the interference fit will firmly keep the T-slider 24 in the first groove 22, thereby ensuring the positional stability of the positioning post 6.

[0054] In this embodiment of the invention, the top height of the photoelectric fixing plate 8 is lower than the top height of the positioning post 6.

[0055] The top of the photoelectric fixing plate 8 is used to install the photoelectric sensor 9. Its height is set lower than the top of the positioning post 6 so as to achieve effective sensing of the FPC product without interfering with the placement and positioning of the FPC product. The main function of the positioning post 6 is to form a positioning groove 7 to accurately limit the position of the FPC product in the horizontal direction. Its higher top height can ensure effective limiting of the edge of the FPC product. The photoelectric sensor 9 mainly senses the presence of the FPC product. It realizes the monitoring function by sensing the upper surface of the FPC product. It does not need to be too high. It only needs to be able to accurately sense the presence or absence of the product.

[0056] In this embodiment of the utility model, the side of the material feeding fixing plate 4 is provided with a mounting hole 26, and the lower end of the photoelectric fixing plate 8 is provided with an elongated hole 27 adapted to the mounting hole 26.

[0057] The mounting hole 26 on the side of the feeding fixing plate 4 and the elongated hole 27 at the lower end of the photoelectric fixing plate 8 cooperate with each other to realize the installation and fine-tuning of the photoelectric fixing plate 8 on the feeding fixing plate 4. The mounting hole 26 is a fixed circular hole, providing a basic installation positioning point, while the elongated hole 27 allows the photoelectric fixing plate 8 to make relative displacement adjustments within a certain range. During the installation process, first align the elongated hole 27 of the photoelectric fixing plate 8 with the mounting hole 26 of the feeding fixing plate 4, and initially fix it with bolts and other connecting parts, but do not tighten it completely. Then, according to actual needs, move the photoelectric fixing plate 8 along the length of the elongated hole 27 to adjust the position of the photoelectric sensor 9 relative to the feeding area to achieve the best photoelectric sensing effect. After adjustment, tighten the connecting parts completely.

[0058] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
