Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical equipment technology, and in particular to an automatic flexible board loading and unloading machine for AOI. Background Technology
[0002] Flexible printed circuit boards (FPCs) are printed circuit boards made using flexible substrates. Unlike traditional rigid printed circuit boards (such as FR-4 PCBs), FPC boards can be bent, folded, and wound, and are therefore widely used in applications where space and weight savings are required.
[0003] With the miniaturization and increasing complexity of electronic products, the quality requirements for FPC boards are also becoming increasingly stringent. AOI inspection, as a crucial step in ensuring FPC board quality, directly impacts the efficiency of the entire production process. However, traditional FPC board inspection typically relies on manual loading and unloading operations. Operators manually place the FPC boards to be inspected onto the AOI inspection platform, complete the inspection, and then manually remove them onto the loading board. This presents several challenges for FPC board inspection. First, manual operation is prone to human error, such as positional deviations and inaccurate angles, all of which affect the AOI inspection results. Second, frequent manual handling increases the risk of FPC boards being bent, creased, torn, or damaged at solder joints, leading to a higher defect rate and additional rework and repair costs.
[0004] Furthermore, manual loading and unloading is slow and cannot meet the efficiency requirements of large-scale production, thus affecting the overall capacity of the production line.
[0005] Therefore, developing an automatic flexible circuit board loading and unloading machine for AOI is of great practical significance. It can improve production efficiency and ensure operational consistency, while reducing overall production costs and enhancing the competitiveness of enterprises in the market. Utility Model Content
[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic flexible board loading and unloading machine for AOI, comprising a cabinet, one side of which has a docking interface for connecting with a testing machine, and the interior of the cabinet having a testing area for placing the testing platform and a functional area surrounding the testing area;
[0008] The functional area is provided with upper and lower plate platforms and a first functional platform and a second functional platform arranged opposite to each other. The upper and lower plate platforms are provided with an upper plate mechanism and a lower plate mechanism, with the upper plate mechanism located on the side closer to the first functional platform and the lower plate mechanism located on the side closer to the second functional platform.
[0009] The first functional platform is equipped with a material gripping mechanism, the second functional platform is equipped with a flipping adsorption mechanism, and the second functional platform is also equipped with a Y-axis linear module that acts on the flipping adsorption mechanism. The material gripping mechanism is used to grip the FPC board to be tested at the upper end of the upper plate mechanism and transfer it to the testing platform, and to grip the FPC board that has completed one side testing on the flipping adsorption mechanism and transfer it to the testing platform.
[0010] The flipping adsorption mechanism is used to flip the FPC board that has completed one-sided testing on the adsorption detection platform, and to adsorb the FPC board that has completed double-sided testing on the adsorption detection platform, and to transfer it to the lower plate mechanism in conjunction with the Y-axis linear module.

[0017] A telescopic power component is also installed on the same side as the suction nozzle rod on the loading and unloading suction cup. The telescopic power component is connected to an impact rod, and a soft rubber head is provided on the impact rod.
[0018] The feeding plate contains FPC boards and partitions, which are placed alternately layer by layer.
[0019] As a further embodiment of this utility model, it also includes a coding mechanism, which is disposed on one side of the flipping and adsorption mechanism and moves with the flipping and adsorption mechanism;
[0020] The coding mechanism performs coding on the FPC board when the board is placed on the lower plate mechanism after the FPC board has completed inspection.
[0021] Compared with existing technologies, the beneficial effects of this technical solution are as follows: Automated loading and unloading allows for continuous and uninterrupted operation, significantly reducing the processing time for each FPC board and improving the overall efficiency of the production line; all operations are completed by machines, eliminating the influence of human factors, ensuring consistency and accuracy in each loading and unloading, while avoiding the risk of physical damage caused by manual handling, protecting the quality of the FPC boards, reducing the defect rate caused by human factors, and saving rework and maintenance costs; it also reduces reliance on manpower and lowers labor costs.
[0022] By cooperating with the material gripping mechanism, the flipping and adsorption mechanism, and the Y-axis linear module, the FPC board can be automatically flipped, thus handling the inspection of FPC boards that require double-sided inspection. This eliminates the need for manual flipping of the FPC board, further reducing human intervention and avoiding the risk of damage to the FPC board that may be caused by manual flipping.

[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 An automatic flexible board loading and unloading machine for AOI includes a cabinet 1, one side of which has a docking interface for connecting with the testing machine, and the inside of the cabinet 1 has a testing area 2 for placing the testing platform and a functional area 3 surrounding the testing area 2.
[0034] Functional area 3 is provided with upper and lower plate platforms 4 and a first functional platform 5 and a second functional platform 6 arranged opposite to each other. The upper and lower plate platforms 4 are provided with an upper plate mechanism 7 and a lower plate mechanism 8, with the upper plate mechanism 7 located on the side closer to the first functional platform 5 and the lower plate mechanism 8 located on the side closer to the second functional platform 6.
[0035] The first functional platform 5 is equipped with a material gripping mechanism 9, the second functional platform 6 is equipped with a flipping adsorption mechanism 10, and the second functional platform 6 is also equipped with a Y-axis linear module 11 that acts on the flipping adsorption mechanism 10.
[0036] In this embodiment, the cabinet 1 of this equipment has an interface for connecting with an AOI (Automated Optical Inspection) machine. When used for FPC board inspection, this equipment connects to the AOI machine via the interface, allowing the inspection platform of the AOI machine to be placed in the inspection area 2 inside the cabinet 1. The functional area 3 surrounding the inspection area 2 integrates and installs multiple key modules. Among these, the gripping mechanism 9 is used to grip the FPC board to be tested from the upper plate mechanism 7 and transfer it to the inspection platform, and to grip the FPC board that has already undergone one-sided inspection from the flipping and adsorption mechanism 10 and transfer it to the inspection platform. The flipping and adsorption mechanism 10 is used to adsorb the FPC board that has already undergone one-sided inspection on the inspection platform and flip it, and to adsorb the FPC board that has undergone double-sided inspection on the inspection platform, and, in conjunction with the Y-axis linear module 11, transfer it to the lower plate mechanism 8. The design principle of these functional modules is based on mechanical motion control and positioning technology. It is equipped with precise drive devices, such as motors and cylinders. By controlling the motion parameters of these drive devices, such as stroke, speed, and force, precise gripping and adsorption of the FPC board are achieved. Combined with position sensors, the position information of the gripping mechanism 9 and the flipping adsorption mechanism 10 can be monitored in real time to ensure the accuracy of the gripping mechanism 9 and the flipping adsorption mechanism 10 in gripping, adsorbing and placing FPC boards. The upper plate mechanism 7 and the lower plate mechanism 8 set on the upper and lower plate platforms 4 are designed such that the upper plate mechanism 7 is close to the side of the first functional platform 5, which is conducive to the gripping mechanism 9 to grip FPC boards quickly and accurately, while the lower plate mechanism 8 is close to the side of the second functional platform 6 to adapt to the movement path of the Y-axis linear module 11 when driving the flipping adsorption mechanism 10, so that the flipping adsorption mechanism 10 can place the FPC board that has been tested into the lower plate mechanism 8. Furthermore, the first functional platform 5 and the second functional platform 6 are set opposite each other and located on both sides of the detection area 2 (i.e., the detection platform). This layout can avoid the movement path conflict between the gripping mechanism 9 and the flipping adsorption mechanism 10. The control system of the entire equipment coordinates the action sequence and time interval between the various mechanisms through preset program instructions to realize the automated process cycle from one gripping and releasing, single-sided testing, adsorption and flipping, secondary gripping and releasing to adsorption and unloading.
[0037] The feeding plate 17 is provided with FPC boards and partitions, and the FPC boards and partitions are placed alternately layer by layer.
[0038] The operating procedure of this utility model is as follows:
[0039] S1. The material grabbing mechanism 9 grabs the FPC board from the upper plate mechanism 7 and places it on the inspection platform, so that the inspection machine can inspect the first side of the FPC.
[0040] S2. After the first side of the FPC board is inspected, the flipping adsorption mechanism 10 adsorbs the FPC and flips it so that the first side of the FPC board faces upward. The flipping adsorption mechanism 10 is moved by the Y-axis linear module 11 so that the position of the flipping adsorption mechanism 10 is offset from the inspection platform.
[0041] S3. The material gripping mechanism 9 grips the FPC board on the flipping and adsorption mechanism 10 and places it on the testing platform, so that the testing machine can test the second side of the FPC board.
[0042] S4. During the FPC board inspection gap, the material gripping mechanism 9 grips the next FPC board to be inspected on the upper plate mechanism 7. At the same time, the Y-axis linear module 11 drives the flipping adsorption mechanism 10 to move above the inspection platform, and the flipping adsorption mechanism 10 flips so that the adsorption surface faces the inspection platform.
[0043] S5. After the second side of the FPC board is inspected, the flipping adsorption mechanism 10 adsorbs the FPC board that has completed double-sided inspection. In cooperation with the Y-axis linear module 11, the FPC board that has completed inspection is placed on the lower plate mechanism 8. After the flipping adsorption mechanism 10 moves, the material grabbing mechanism 9 places the next FPC board to be inspected on the inspection platform so that the inspection machine can inspect the first side of the next FPC board to be inspected.
[0044] S6. During the gap when the first side of the next FPC board to be inspected is inspected, the flipping adsorption mechanism 10 moves to the top of the inspection platform in cooperation with the Y-axis linear module 11. At the same time, the material grabbing mechanism 9 grabs the partition paper on the upper plate mechanism 7, and when the flipping adsorption mechanism 10 has finished adsorbing the FPC board that has finished inspecting the first side, it places the partition paper on the lower plate mechanism 8 to complete the inspection of the FPC board.
[0045] The FPC detection operation is performed continuously through the S1-S6 cycle.
[0046] In summary, this invention enables continuous and uninterrupted operation through automatic loading and unloading, significantly reducing the processing time for each FPC board and improving the overall efficiency of the production line. All operations are completed by the machine, eliminating the influence of human factors, ensuring consistency and accuracy in each loading and unloading, while avoiding the risk of physical damage caused by manual handling, protecting the quality of the FPC boards, reducing the defect rate caused by human factors, and saving rework and maintenance costs. It also reduces reliance on manpower and lowers labor costs.
[0047] Through the cooperation of the material gripping mechanism 9, the flipping and adsorption mechanism 10 and the Y-axis linear module 11, the FPC board can be automatically flipped, thus handling the inspection of FPC boards that require double-sided inspection. There is no need for manual flipping of the FPC board, further reducing human intervention and avoiding the risk of damage to the FPC board caused by manual flipping.
[0048] The Y-axis linear module 11 consists of a Y-axis drive motor, a Y-axis synchronous pulley, a Y-axis synchronous belt, a ball screw, and a slide rail. The flipping adsorption mechanism 10 is slidably connected to the slide rail. The Y-axis drive motor drives the synchronous pulley to rotate. The Y-axis synchronous pulley, Y-axis synchronous belt, and ball screw convert the rotational motion into linear motion, thereby driving the flipping adsorption mechanism 10 to translate. The flipping adsorption mechanism 10 can be translated along the Y-axis.
[0049] In this embodiment, reference Figure 3 Furthermore, it is proposed that the material handling mechanism 9 includes a robotic arm 12, and the robotic arm 12 is driven and connected to a loading and unloading suction cup 13;
[0050] The robotic arm 12 is a six-axis robot with six rotary joints, enabling complex movements in three-dimensional space and easily handling various posture adjustments. This six-axis robot is combined with loading / unloading suction cups 13, and the gripping process is monitored in real time through an integrated vision system and torque sensors. This significantly improves the efficiency, accuracy, and reliability of the automated FPC board loading / unloading system. This configuration not only adapts to complex production environments and diverse FPC board types but also facilitates future expansion and upgrades.
[0051] In this embodiment, reference Figure 3 Furthermore, the flipping adsorption mechanism 10 is proposed to include a flipping suction cup 14, a flipping drive assembly 15, and a Z-axis moving module 16;
[0052] The flip drive assembly 15 is connected to the flip suction cup 14, and the Z-axis moving module 16 acts on the flip suction cup 14 and the flip drive assembly 15 to drive the flip suction cup 14 and the flip drive assembly 15 to perform Z-axis movement.
[0053] The flipping adsorption mechanism 10 also includes a frame 27 connected to the Y-axis linear module 11. A Z-axis moving module 16 is mounted on the frame 27. The Z-axis moving module 16 consists of a Z-axis drive motor, a Z-axis synchronous pulley, a Z-axis synchronous belt, a Z-axis lead screw, and a first lead screw synchronous pulley. The Z-axis synchronous belt is sleeved on the Z-axis synchronous pulley and the first lead screw synchronous pulley to drive the lead screw to rotate. A Z-axis block is screwed onto the Z-axis lead screw to drive the Z-axis block to move. A tooling plate 28 is connected to the outside of the Z-axis block. The tooling plate 28 is used to connect to the flipping suction cup 14 and the flipping drive assembly 15. The specific working principle of the Z-axis moving module 16 is as follows: the Z-axis drive motor starts and drives the Z-axis synchronous pulley to rotate. The Z-axis synchronous pulley drives the first lead screw synchronous pulley to rotate through the Z-axis synchronous belt, which in turn drives the Z-axis lead screw to rotate, so that the Z-axis block drives the tooling plate 28 to move in the Z-direction, thereby driving the flipping suction cup 14 and the flipping drive assembly 15.
[0054] The flip suction cup 14 is provided with a first air supply pipe 29. The tooling plate 28 has a through hole, and a rotary bearing sleeve is installed in the through hole. The first air supply pipe 29 passes through the rotary bearing sleeve and is rotatably connected to a second air supply pipe 30. The flip drive assembly 15 consists of a flip drive motor, a flip synchronous pulley, a transmission synchronous pulley sleeved on the first air supply pipe 29, and a flip synchronous belt sleeved on the flip synchronous pulley and the transmission synchronous pulley. The second air supply pipe 30 is offset from the flip drive motor. The first air supply pipe 29 is connected to the air pipe connector on the flip suction cup 14 through an air pipe. The bottom surface of the flip suction cup 14 has suction holes for adsorbing FPC boards. The flip drive motor drives the flip synchronous pulley to rotate, and the flip synchronous belt drives the transmission synchronous pulley, which in turn drives the first air supply pipe 29 to drive the flip suction cup 14 to flip. The first air supply pipe 29 and the second air supply pipe 30 are rotatably connected (e.g., through a sealed bearing) so that the second air supply pipe 30 is not driven during flipping to avoid conflict between the second air supply pipe 30 and other components.
[0055] When flipping is required, the Z-axis moving module 16 drives the flipping suction cup 14 and the flipping drive component 15 to move along the Z-axis (i.e., rise away from the detection platform). Then, the flipping drive component 15 drives the flipping suction cup 14 to flip. The position of the flipping suction cup 14 can be flexibly adjusted to avoid conflict with the detection platform during the flipping process. Through the cooperation of the Z-axis moving module 16 and the flipping drive component 15, the flipping suction cup 14 can be controlled to approach the FPC board and then move away from the detection platform to perform the flipping operation of the FPC board.
[0056] In this embodiment, reference Figures 3-4 Furthermore, the upper plate mechanism 7 includes an upper plate 17 disposed on the upper and lower plate platforms 4 and an upper plate lifting component 18 disposed at the lower end of the upper and lower plate platforms 4 and acting on the upper plate 17.
[0057] The lower plate mechanism 8 includes a lower plate 19 disposed on the upper and lower plate platforms 4 and a lower plate lifting assembly 20 disposed at the lower end of the upper and lower plate platforms 4 and acting on the lower plate 19.
[0058] The loading plate 17 and unloading plate 19 serve as the base for loading and unloading the FPC board. Their shapes can be designed to match the shape of the FPC board, and limiting components can also be added, such as... Figure 3 As shown, the loading plate 17 and unloading plate 19 are surrounded by a partition plate, which is installed on the loading and unloading platform 4. The addition of the partition plate can facilitate the neat placement of multi-layer FPC boards on the loading plate 17 during manual stacking, so as to avoid positional deviation during material handling and affect the detection accuracy. It can also facilitate the placement of FPC boards that have been inspected on the unloading plate 19, so as to prevent the FPC boards from slipping and shifting when the number of layers of FPC boards increases.
[0059] On the surrounding plates of the loading plate 17 and the unloading plate 19, photoelectric sensors are added. Through the cooperation of the photoelectric sensors with the loading lifting assembly 18 and the unloading lifting assembly 20, the feeding and unloading of FPC boards can be assisted. Among them, after precise adjustment, the photoelectric sensor acting on the loading plate 17 can accurately sense the topmost FPC product, while the photoelectric sensor acting on the unloading plate 19 can accurately sense the empty space above the topmost FPC. The photoelectric sensor usually adopts the principle of infrared emission and reception. When an FPC product blocks the infrared light path, the photoelectric sensor will generate a corresponding signal change to determine the presence and position of the product.
[0060] Taking the upper loading plate 17 and the loading lifting assembly 18 as an example, in the initial state, the photoelectric sensor can sense the uppermost FPC board. When there is an FPC board to be detected on the loading plate 17, after the upper FPC board is grabbed, the photoelectric sensor detects that the uppermost product has disappeared and transmits the signal to the control system. After receiving the signal, the control system controls the loading lifting assembly 18 to start working, so as to drive the loading plate 17 to move upward, thereby making the uppermost FPC board placed on the loading plate 17 rise to the position that the photoelectric sensor can sense. This ensures that the FPC board is at a suitable height every time it is picked up, which facilitates the automatic picking equipment to perform accurate picking operations and ensures the continuity and efficiency of the picking process.
[0061] Similarly, in the cooperation between the unloading plate 19 and the unloading lifting assembly 20 and the corresponding photoelectric sensor, the initial state is that the photoelectric sensor cannot detect the uppermost FPC board in the unloading plate 19. When the FPC board that has completed the test is placed on the unloading plate 19, the photoelectric sensor detects the presence of the FPC board and transmits the signal to the control system. After receiving the signal, the control system controls the unloading lifting assembly 20 to start working, so as to drive the unloading plate 19 to move downward until the photoelectric sensor can no longer detect the presence of the FPC board and stops. This ensures that the uppermost stacked FPC board in the unloading plate 19 is lower than the flipping adsorption mechanism 10, so that each time the FPC board that has completed the test is placed on the unloading plate 19, it will not conflict with the previously placed FPC board, preventing accidental collisions.
[0062] The loading lifting assembly 18 includes a mounting plate and a base plate. A lifting drive motor is mounted on the mounting plate, and a lifting screw with a bearing sleeve and a through-bearing sleeve is set on the base plate. The top of the lifting screw is fixedly connected to the upper and lower plate platforms 4 through a fixing plate. The drive output of the lifting drive motor includes a lifting synchronous pulley. The bottom of the lifting screw has a second screw synchronous pulley, and a lifting synchronous belt is sleeved between the lifting synchronous pulley and the second screw synchronous pulley. A lifting block is screwed onto the lifting screw, and a lifting plate is sleeved on the lifting block. A lifting rod is connected to the lifting plate, and the lifting rod passes through the upper and lower plate platforms 4 and is fixedly connected to the loading plate 17. The lifting drive motor is started to drive the lifting synchronous pulley to rotate. The lifting synchronous pulley drives the second screw synchronous pulley to rotate through the lifting synchronous belt, causing the lifting block on the screw to move up and down, thereby driving the lifting plate. The lifting plate drives the loading plate to move up and down through the lifting rod. Similarly, the unloading lifting assembly 20 has the same structure as the loading lifting assembly 18, and will not be described in detail here.
[0063] In this embodiment, reference Figure 5 Furthermore, it is proposed that the loading and unloading suction cup 13 is equipped with several suction rods 21, and suction rods 21 are equipped with suction nozzles 22. The loading and unloading suction cup 13 is also equipped with a vacuum generator. The vacuum generator is connected to the suction rods 21 at the lower end. When the material is gripped, the vacuum generator starts to work, so that the suction rods 21 and suction nozzles 22 generate vacuum suction force, thereby gripping the FPC board. Then, the robot arm 12 is used to control the precise transfer and placement of the FPC board.
[0064] On the same side as the suction rod 21, the loading and unloading suction cup 13 is also equipped with a telescopic power component 23. The telescopic power component 23 is connected to an impact rod 24, and a soft rubber head 25 is provided on the impact rod 24.
[0065] The loading and unloading suction cup 13, in addition to the suction rod 21 and suction nozzle 22, is also equipped with a telescopic power component 23 (such as a telescopic cylinder or electric telescopic rod). The telescopic power component 23 is connected to the impact rod 24. When gripping the FPC board and the partitions that are placed alternately with the FPC board, the telescopic power component 23 is activated to drive the impact rod 24 to move back and forth, thereby continuously impacting the FPC board or partition. At this time, the FPC board or partition is sucked by the suction nozzle 22. Therefore, the impact of the impact rod 24 cannot knock down the sucked FPC board or partition. Instead, it can knock down the product of the next layer. This prevents the product of the next layer from being pulled when the surface FPC board or partition is gripped. Because the suction force on the next layer is insufficient, once the product of the next layer is pulled, it is easy to fall during the transfer process, resulting in damage.
[0066] In this embodiment, reference Figures 1-4Furthermore, it is proposed that a coding mechanism 26 is also included. The coding mechanism 26 is disposed on one side of the flipping adsorption mechanism 10 and moves with the flipping adsorption mechanism 10. The coding mechanism 26 performs coding on the FPC board when the FPC board is placed on the lower plate mechanism 8 after the FPC board has been inspected.
[0067] After the FPC board completes inspection, the flipping and adsorption mechanism 10 places the FPC board onto the lower plate mechanism 8. The inkjet printing mechanism 26, which moves with the flipping and adsorption mechanism 10, performs inkjet printing on the FPC board to achieve product identification, tracking and management. By printing specific information on the FPC board, enterprises can more effectively carry out quality control, inventory management and after-sales service.
[0068] 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 illustrative 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. No reference numerals in the claims should be construed as limiting the scope of the claims.
