Description

Technical Field

[0001] This invention belongs to the field of automated production of display panels, and more specifically, relates to a fully automated FPC insertion production line system, a panel inspection device, and a method. Background Technology

[0002] FPC stands for Flexible Circuit Board (Flexible PCB), also known as "flexible board". FPC is often used in applications requiring repeated bending and for connecting small components, such as the bending parts of a mobile phone flip cover, the parts connecting the print head of a printing device, etc.

[0003] Today, electronic products are becoming increasingly smaller, demanding higher precision in connecting FPCs (Flexible Printed Circuits) to PCBs. Current P-board carriers often only accommodate one or a few PCB sizes, lacking flexibility and unable to adapt to multiple sizes, irregular shapes, and large PCBs. Automated insertion equipment also suffers from inaccurate positioning, leading to misinsertion, improper PCB-FPC connection, chip loss, and damage to PCB interfaces. Furthermore, the inability of existing FPCs to continuously and automatically feed them results in low production efficiency.

[0004] Therefore, it is necessary to develop a fully automated FPC splicing production line system to improve the existing fully automated FPC splicing production line in all aspects and stages, so as to improve splicing efficiency, splicing accuracy and splicing quality. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide an FPC fully automatic insertion production line system, panel inspection device and method. In terms of concept, the device of this invention considers all aspects of feeding, insertion and positioning, and comprehensively improves the structure to achieve continuous automatic feeding and accurate and high-quality insertion.

[0006] To achieve the above objectives, a first aspect of the present invention provides a fully automated FPC insertion production line system, comprising a feeding mechanism, an insertion mechanism, and a PCB board positioning mechanism. The insertion mechanism is positioned above the stations of the feeding mechanism and the PCB board positioning mechanism, and is flexibly movable. It is used to pick up and transfer FPCs from the feeding mechanism station to the insertion station of the PCB board positioning mechanism, and insert the FPCs onto the PCB board. The PCB board positioning mechanism is used to fix PCB boards with different specifications of FPCs to be inserted to a set position. The feeding mechanism is used to continuously and stably provide FPCs automatically. The PCB board positioning mechanism includes a Y-axis moving component and a Y-axis limiting stage that are relatively arranged and have an adjustable spacing. The Y-axis moving component can move along the Y-axis, while the Y-axis limiting stage remains stationary.

[0007] In the above invention concept, the feeding mechanism is used to continuously and stably provide FPC automatically, the PCB board positioning mechanism can firmly fix PCB boards of various specifications, and the insertion mechanism can accurately and flexibly insert FPC. By considering and improving from multiple angles and aspects, the insertion efficiency, insertion accuracy and insertion quality can be effectively improved.

[0008] Furthermore, there are multiple sets of Y-axis moving components and multiple independent Y-axis limiting stages. The multiple sets of Y-axis moving components are parallel to each other and independent of each other. Each set of Y-axis moving components is set opposite to the corresponding Y-axis limiting stage. The multiple independent Y-axis moving components can move along the Y-axis as needed to adjust the distance between them and the Y-axis limiting stage, thereby adapting to the clamping and fixing of P-plates of different specifications.

[0009] Furthermore, it also includes a Z-axis moving component and an X-axis moving component. The X-axis moving component has multiple parallel and independent units. The multiple X-axis moving components are movably arranged on the same slide rail so that they can move along the X-axis. The slide rail is set on the platform of the Z-axis moving component. Each Y-axis moving component is set on the X-axis moving component. The Y-axis limiting stage is fixed on the platform of the Z-axis moving component.

[0010] Furthermore, the feeding mechanism includes a continuous active feeding unit and a support frame that supports and assists the continuous feeding unit. The continuous active feeding unit includes a power component, a lifting connector, a lifting plate, and a vertical plate. The vertical plate is vertically fixed, the power component is fixed to the top of one side of the vertical plate, and the lifting plate is located on the opposite side of the vertical plate and connected to the power component via the lifting connector, so that it can automatically rise and fall under drive. The lifting plate is used to place the FPC. In the above inventive concept, the power component drives the lifting plate through the lifting connector to push the FPC out.

[0011] Furthermore, it also includes a limiting plate, which is set at the top of the upright plate to limit the position of the lifting plate, so as to ensure that the lifting plate rises to the limited position to push out an FPC for the next station. It also includes slides, a pair of slides are arranged parallel to each other on one side of the upright plate, and the lifting connector is slidably connected to the pair of slides. It also includes FPC insertion columns, which are set on the front side of the upright plate and are columnar, used to cooperate with the side upright plate and the horizontal lifting plate to form a hopper for stacking multiple FPCs. The FPC insertion column includes two rods with adjustable spacing arranged side by side, which can be adjusted to accommodate the insertion of FPCs of various specifications.

[0012] Furthermore, the insertion mechanism includes a movable robotic arm and an insertion component and an opening / closing cover component driven by the movable robotic arm. The insertion component and the opening / closing cover component are connected as one unit. The insertion component is used to pick up and transfer the FPC on the loading mechanism station to the insertion station of the PCB board positioning mechanism and insert the FPC onto the PCB board. The opening / closing cover component is used to open the piano cover on the PCB board before the FPC is inserted into the PCB board and close the piano cover on the PCB board after the insertion action is completed.

[0013] Furthermore, the plug-in assembly includes a driving component, a driving transmission component, a clamping component, and a motion guide component. The driving component is connected to the clamping component through the driving transmission component to provide motion power to the clamping component. The motion guide component is fixed, and the clamping component is movably connected to the motion guide component so that it can undergo predetermined translation and rotation under the constraint of the motion guide component after being driven by the driving component. The clamping component includes a clamping plate and / or an adsorption component for performing clamping transfer or adsorption transfer on the current FPC.

[0014] Furthermore, the opening and closing cover assembly includes a power source, an opening and closing cover plate, and a flexible contact. The power source is connected to the opening and closing cover plate to drive the opening and closing cover plate to push or retract. The flexible contact is disposed at the end of the opening and closing cover plate and is connected to the elastic body of the opening and closing cover plate. The flexible contact has an arc-shaped toe and an arc-shaped heel. The toe is used to kick open the piano cover of the PCB board during the trajectory movement of the opening and closing cover plate during the pushing phase. After the insertion is completed, the heel is used to bring the piano cover back and flexibly touch and press the piano cover during the trajectory movement.

[0015] According to a second aspect of the invention, a panel inspection device is also provided, comprising the FPC fully automated insertion production line system as described above.

[0016] According to a third aspect of the present invention, a method for operating the FPC fully automated insertion production line system as described above is provided, comprising the following steps:

[0017] S1: The feeding mechanism actively pushes out an FPC.

[0018] S2: The insertion mechanism picks up the FPC from the loading station and moves it to the PCB board to be inserted.

[0019] S3: Collect photos of the PCB board position to determine the precise position of the PCB board insertion station in real time. Open the piano cover according to the position of the PCB board insertion station, insert the FPC into place, and close the piano cover while the insertion mechanism is retracting into place after insertion is completed. Gently touch and press the piano cover.

[0020] In summary, compared with the prior art, the above-described technical solutions conceived by this invention have the following advantages:

[0021] Beneficial effects:

[0022] In this invention, the feeding mechanism is used to continuously and stably provide FPC automatically, the PCB board positioning mechanism can firmly fix PCB boards of various specifications, and the insertion mechanism can accurately and flexibly insert FPC. By considering and improving from multiple angles and aspects, the insertion efficiency, insertion accuracy and insertion quality can be effectively improved.

[0023] Firstly, the design incorporates a power-driven lifting plate to push the FPC out, and a limiting plate positioned at the top of the upright plate ensures that the lifting plate reaches the designated position to push out an FPC for use at the next workstation. The FPC insertion columns, in conjunction with the side upright plates and the horizontal lifting plate, form a hopper for stacking multiple FPCs. Each insertion column includes two adjustable-spaced, side-by-side rods to accommodate various FPC specifications. This structural design enables temporary storage and automatic, continuous feeding of FPCs of different specifications.

[0024] Secondly, the insertion mechanism is designed to include a movable robotic arm and an insertion component and an opening / closing cover component driven by the movable robotic arm. The insertion component includes a driving component, a driving transmission component, a clamping component, and a motion guide component, which can pick up and transfer the FPC on the loading mechanism station to the insertion station of the PCB board positioning mechanism, and insert the FPC onto the PCB board. The opening / closing cover component includes a power source, an opening / closing cover plate, and a flexible contact. The opening / closing cover component can open the piano cover on the PCB board and automatically close the piano cover on the PCB board after the insertion action is completed.

[0025] Thirdly, the PCB board positioning mechanism is designed to include a Y-axis moving component and a Y-axis limiting stage. Each Y-axis moving component is set opposite to the Y-axis limiting stage. Multiple independent Y-axis moving components can move along the Y-axis as needed to adjust the distance between them and the Y-axis limiting stage. This design can adapt to the clamping and fixing of P-boards of different specifications.

[0026] The combined effect of these three main improvements ensures continuous and automatic feeding, as well as precise and reliable insertion. It also realizes an insertion method that effectively improves insertion efficiency, accuracy, and quality. Attached Figure Description

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0039] Figure 1 This is a first axial view of an FPC fully automated insertion production line system provided in an embodiment of the present invention. Figure 2 This is a second axis view of an FPC fully automated insertion production line system provided in an embodiment of the present invention. Figure 3This is a rear view of an FPC fully automated insertion production line system provided by an embodiment of the present invention. As shown in the three figures, the FPC fully automated insertion production line system provided by the present invention includes a feeding mechanism 100, an insertion mechanism 200, and a PCB board positioning mechanism 300. These three mechanisms cooperate and work together. The insertion mechanism 200 is positioned above the feeding mechanism 100 and the PCB board positioning mechanism 300. The feeding mechanism 100 and the PCB board positioning mechanism 300 are located at the operating table of the entire automated insertion production line system. The insertion mechanism, positioned above the operating table, moves as needed. It picks up and transfers FPCs from the feeding mechanism 100 to the insertion station of the PCB board positioning mechanism 300, and inserts the FPCs onto the PCB board. The PCB board positioning mechanism 300 is used to fix PCB boards with various specifications of FPCs to be inserted to a set position. The feeding mechanism 100 continuously and stably provides FPCs automatically.

[0040] Figure 1 This is a first axial view of an FPC fully automated insertion production line system provided in an embodiment of the present invention. Figure 4 This is a first axial view of the feeding mechanism provided in an embodiment of the present invention. Figure 5This is a second axial view of the feeding mechanism provided in this embodiment of the invention. As can be seen from the above three figures, the feeding mechanism includes a continuous active feeding unit 101 and a support frame 102 that supports and assists the continuous feeding unit 101. The support frame 102 is part of the operating table of the entire FPC fully automatic insertion assembly line system. The continuous active feeding unit 101 includes a power component 1011, a lifting connector 1012, a lifting plate 1013, and a vertical plate 1014. The vertical plate 1014 is vertically fixed. The power component 1011 is fixed to the top of one side of the vertical plate 1014 and is used to drive the lifting plate to move up and down. The power component can be, for example, a servo cylinder, a hydraulic cylinder, a lead screw mechanism, or a spring, preferably a constant spring, whose force is constant and controllable. The lifting plate 1013 is located on the opposite side of the vertical plate 1014 and is connected to the power component 1011 through the lifting connector 1012, so that it can automatically rise and fall under the drive of 1011. The lifting plate 1013 is used to place the FPC. A limiting plate 1015 is located at the top of the upright plate 1014 to limit the position of the lifting plate 1013, ensuring that the lifting plate rises to the limited position to push out an FPC for use at the next station. A pair of slide rails 1016 are arranged parallel to each other on one side of the upright plate. The lifting connector 1012 is slidably connected to the pair of slide rails 1016. An FPC insertion column 1017 is located on the front side of the upright plate, in a columnar shape, to cooperate with the side upright plate and the horizontal lifting plate to form a hopper for stacking multiple FPCs. The FPC insertion column 1017 includes two adjustable-spacing rods arranged side by side. By adjusting the spacing between the rods, it can accommodate the insertion of various specifications of FPCs. For example, the spacing between the two adjustable-spacing rods can be adjusted by a forward and reverse thread structure.

[0041] In one specific embodiment, a constant spring is used as the power component. The constant spring is connected to the lifting plate via a lifting connector 1012 that meets the actual engineering requirements. The lifting plate is designed according to the shape of the FPC to be placed. At the start of loading, the lifting plate lowers to its lowest position, and a thick stack of FPC sheets is placed on it. At this time, the hopper is full, and the FPCs are simultaneously inserted by the inserting columns. The combined action of the inserting columns, the vertical plate, and the lifting plate forms a temporary storage space conforming to the shape of the FPC. As each FPC is removed, the lifting plate gradually rises. Under the action of the limiting plate, the lifting plate stops at a set position, ensuring that the next FPC is automatically ejected after the previous one is removed.

[0042] Figure 1 This is a first axial view of an FPC fully automated insertion production line system provided in an embodiment of the present invention. Figure 6 This is a first axial view of the insertion mechanism provided in an embodiment of the present invention. Figure 7This is a second axial view of the insertion mechanism provided in an embodiment of the present invention. As shown in the three figures, the insertion mechanism 200 includes a movable robotic arm 201, an insertion component 202 driven by the movable robotic arm, and an opening / closing cover component 203. The insertion component 202 and the opening / closing cover component 203 work together and can be connected as a single unit. The insertion component 202 is used to pick up and transfer the FPC from the loading mechanism station to the insertion station of the PCB board positioning mechanism 300, and insert the FPC onto the PCB board. The opening / closing cover component 203 is used to open the piano cover on the PCB board before the FPC insertion action occurs, and to close the piano cover on the PCB board after the insertion action is completed.

[0043] Specifically, the plug-in assembly 202 includes a driving member 2021, a driving transmission member 2022, a clamping member 2023, and a motion guide member 2024. The driving member 2021 is connected to the clamping member 2023 via the driving transmission member 2022 to provide motion power to the clamping member 2023. The motion guide member 2024 is fixed and mounted on the basic frame of the entire plug-in mechanism 200. The clamping member 2023 is movably connected to the motion guide member 2024 so that it can undergo predetermined translation and rotation under the constraint of the motion guide member 2024 after being driven by the driving member 2021. The clamping member 2023 includes a clamping plate and / or an adsorption member for performing clamping transfer or adsorption transfer on the current FPC.

[0044] In one specific embodiment, the adsorption surface of the suction element of the clamping member 2023 can be approximately equivalent to the insertion working surface. A vacuum adsorption plate is provided on the suction element, integrating it onto the clamping member, allowing for flexible selection of clamping methods. When in the clamping state, the clamping plate is in an open-mouthed state. Driven, it rotates around a fixed point, causing the clamping plate to rotate relative to the adsorption surface of the suction element and close, resulting in a closed-mouth clamping state. The driving component is a telescopic cylinder, but it can also be a hydraulic cylinder, lead screw, rotating cam, or other power structure; any structure capable of achieving controllable reciprocating motion of the clamping member can be interchanged. Preferably, a telescopic cylinder can be used, with its piston rod fixed to one end of the driving transmission component and the other end movably connected to the clamping member. The clamping member is driven by the telescopic cylinder to translate and rotate. The motion guide 2024 is a motion guide seat. The motion guide structure is designed according to the motion trajectory of the clamping member and is not limited to a fixed form and structure like a motion guide seat. The motion guide seat is fixed, for example, it can be suspended from the base of the entire device. The main function of the motion guide seat is to guide the clamping component to first translate towards the adsorption surface and then rotate after translation into place. The structure that achieves the above functions is designed to match the structure of the clamping component. The motion guide seat provides suspension support for the connecting component. Preferably, the motion guide seat has two guide grooves or guide holes located obliquely upward and downward, respectively. The clamping component is movably connected in the two guide grooves or guide holes of the motion guide seat so that it is limited by the guide grooves or guide holes to translate and rotate. More specifically, the motion guide seat includes two independent and oppositely arranged motion guide plates. The obliquely upward guide groove or guide hole of each motion guide plate is straight, and the obliquely downward guide groove or guide hole is curved. The curved guide groove is formed by a long side channel and a short side channel connected together. The long side channel is parallel to the obliquely upward straight guide groove or guide hole, and the short side channel extends away from the obliquely upward straight guide groove or guide hole. The above structure specifically demonstrates how the movement of the clamping component is guided by a guide groove or guide hole. The clamping component is translated along the straight guide groove or guide hole at the upper angle and the long side channel at the lower angle. After the translation is completed, the clamping component slides downward under the guidance of the short side channel at the lower angle. At the same time, it rotates around one end of the straight guide groove or guide hole at the upper angle, causing the inclined surface at the end of the clamping component to rotate until it is parallel to the adsorption surface of the adsorption component, thereby achieving the contact between the clamping plate and the adsorption surface.

[0045] In another embodiment, the drive transmission member 2022 is block-shaped, with one end being a bayonet or threaded shape, which is fixedly connected to the piston rod of the lifting cylinder through the bayonet or thread, and the other end being a plate body. The two opposite sides of the plate body are provided with hinge pins, which are inserted into the clamping member to drive the clamping member to move.

[0046] The opening and closing cover assembly 203 includes a power source 2031, an opening and closing cover plate 2032, and a flexible contact 2033. The power source 2031 is connected to the opening and closing cover plate 2032 to drive the opening and closing cover plate 2032 to push or retract. The flexible contact 2033 is disposed at the end of the opening and closing cover plate 2032 and is connected to the elastic body of the opening and closing cover plate 2032. The flexible contact 2033 has an arc-shaped toe and an arc-shaped heel. The toe is used to kick open the piano cover of the PCB board during the pushing phase of the closing phase of the cover plate 2032, and during the retraction phase after the insertion is completed, the heel is used to bring the piano cover back and flexibly touch and press the piano cover.

[0047] In one specific embodiment of the present invention, the power source 2031 is, for example, a hydraulic cylinder, a hydraulic oil cylinder, a motor lead screw, etc. When the piano lid is opened, the opening and closing cover plate 2032 moves as a whole under the drive of the power source 2031, and the flexible contact 2033 opens the piano lid. After the FPC is connected, the opening and closing cover plate 2032 moves the flexible contact 2033 under the drive of the power source 2031. During the movement, the flexible contact 2033 comes into contact with the piano lid. During the contact, it squeezes the elastic element provided in the opening and closing cover plate, and then the elastic element generates a rebound force acting on the piano lid, finally pressing the piano lid tightly.

[0048] In one specific embodiment of the present invention, the flexible contact is also provided with an air blowing hole, which can be used to open the piano lid by blowing air, and can be used as one of the backup methods.

[0049] The flexible lid-closing head is also equipped with an air blowing hole. By flexibly setting the air pressure, the piano lid can be opened without contact. As an effective supplement to the robotic arm for opening the lid, the method of opening the piano lid can be flexibly selected according to different materials during actual operation, which enriches the applicability of the equipment and improves the efficiency of the equipment.

[0050] Figure 1 This is a first axial view of an FPC fully automated insertion production line system provided in an embodiment of the present invention. Figure 8 This is a first axial view of the PCB board positioning mechanism provided in an embodiment of the present invention. Figure 9This is a side view of the PCB board positioning mechanism provided in the embodiment of the present invention. As can be seen from the three figures, the PCB board positioning mechanism 300 includes a Y-direction moving component 301 and a Y-direction limiting stage 302. Multiple sets of Y-direction moving components 301 are parallel to each other and independent of each other. Each set of Y-direction moving components 301 is arranged opposite to the Y-direction limiting stage 302. Multiple independent Y-direction moving components 301 can move along the Y direction as needed to adjust the distance between them and the Y-direction limiting stage 302, thereby adapting to the clamping and fixing of P boards of different specifications. It also includes a Z-axis moving component (303) and an X-axis moving component (304). The X-axis moving component (304) has multiple parallel and independent units. The multiple X-axis moving components (304) are movably arranged on the same slide rail (305) so that they can move along the X direction. The slide rail (305) is set on the platform of the Z-axis moving component (303). Each Y-axis moving component 301 is set on the X-axis moving component (304). The Y-axis limiting stage 302 is fixed on the platform of the Z-axis moving component (303).

[0051] Specifically, in one embodiment of the present invention, there are ten X-axis moving components. A slide rail 305 is disposed on the Z-axis moving component, which can move along the Z-axis. In a specific embodiment, the Z-axis moving component is fixed to an external fixed plate, for example, via a linear slide rail. The Z-axis moving component is generally flat, and its bottom surface can be formed by a triangular support plate and a vertical plate connected at right angles, forming a support platform with a right-angled cross-section. This support platform is connected by a vertically arranged linear slide rail, which is mounted on the external vertical fixed plate. The Z-axis moving component is driven by power to move up and down along the linear slide rail. The power source may be a hydraulic pneumatic system, a hydraulic cylinder, a spring, etc. Each X-axis moving component is equipped with a Y-axis moving component, which is disposed on the X-axis moving component or connected to it side-by-side. There are multiple sets of Y-axis moving components, which are parallel to each other and independent. Each Y-axis moving component is connected to its corresponding X-axis moving component to move along with the X-axis moving component in the X-axis direction. In one embodiment of the present invention, the X-axis moving component is similar to a flat plate and is mounted on a sliding structure. Its tail is provided with a lead screw and a handle. By rotating the handle, the lead screw is adjusted. The lead screw is similar to a set screw, which locks the X-axis moving component in place and does not need to move further. Conversely, by loosening the lead screw, the X-axis moving component can be moved so that it can be moved as needed.

[0052] The Y-axis limiting stage 302 can be a split type with multiple positioning and fixing stages featuring smooth grooves, or it can be an integrated positioning stage. Multiple independent Y-axis moving components can move independently along the Y-axis as needed to adjust the distance between the positioning and fixing components, thus adapting to the clamping and fixing of P-plates of different specifications. During operation, the P-plate is held in place by the two sides of the Y-axis moving components and the positioning and fixing components.

[0053] In the above scheme, a Z-axis moving component is set up, and the X-axis moving component, Y-axis moving component, and Y-axis limiting stage are all configured on the Z-axis moving component. They can move up and down with the Z-axis moving component to adapt to different material heights, making it more flexible to use. Multiple independent X-axis moving components are set up to flexibly adjust the clamping position in the X direction. Each X-axis moving component is equipped with an independent Y-axis moving component, which can further adjust the clamping distance along the Y direction. This invention application allows for independent adjustment of the clamping position and clamping distance in three dimensions, which can adapt to different material heights and sizes, making it a more flexible and convenient P-plate stage.

[0054] The Y-axis moving component includes a first Y-axis adjustment sub-module and a second Y-axis adjustment sub-module. The first Y-axis adjustment sub-module is mounted on the X-axis moving component, and the second Y-axis adjustment sub-module is movably mounted on the first Y-axis adjustment sub-module to move along the moving direction of the first Y-axis adjustment sub-module. This two-tiered Y-axis moving component allows the first Y-axis adjustment sub-module to accommodate P-plates with varying widths, while the second Y-axis adjustment sub-module can accommodate irregularly shaped P-plates with inconsistent widths. In short, regardless of the width of the P-plate, the two-tiered Y-axis adjustment ensures adaptability and flexible adjustment of the clamping distance.

[0055] The present invention also provides a panel inspection device including the fully automated FPC insertion production line system described above. The panel inspection device is used in conjunction with the panel mura repair and removal equipment in the module process to complete the automatic opening and closing of the PBC board and the automatic FPC wiring before feeding, thereby ensuring that the downstream equipment can realize the screen display function.

[0056] The working method of the FPC fully automated insertion production line system described above includes the following steps:

[0057] S1: The feeding mechanism 100 actively pushes out one FPC.

[0058] S2: The insertion mechanism 200 picks up the FPC from the loading mechanism station and moves it to the PCB board to be inserted.

[0059] S3: Collect a photo of the PCB board position to determine the precise position of the PCB board insertion station in real time. Open the piano cover according to the position of the PCB board insertion station, insert the FPC into place, and close the piano cover while the insertion mechanism 200 is retracting into place after insertion is completed. Gently touch and press the piano cover.

[0060] More specifically, the operation is as follows: First, the hopper of the feeding mechanism is filled to capacity. The power component 1011 of the feeding mechanism 100 drives the lifting plate, which actively pushes out an FPC. Next, the insertion mechanism 200 picks up the FPC from the feeding mechanism station, either by suction or by biting, and moves it to the PCB board to be inserted. Simultaneously, the PCB board positioning mechanism clamps the PCB board to be inserted. Then, the insertion mechanism first takes a picture of the PCB board to capture its precise position. Based on this precise position, the robotic arm of the insertion mechanism makes fine adjustments to ensure that the FPC piece picked up on the insertion mechanism 200 can be accurately inserted. According to the position of the PCB board insertion station, the insertion structure moves down with the FPC. The flexible contact first kicks open the piano lid to expose the insertion interface. Then, the insertion mechanism leans forward to perform the insertion action. After insertion, the suction device or clamping plate is released, and the insertion mechanism moves backward. During the backward movement, the flexible contact touches the open piano lid and brings it back to a closed state from the back of the piano lid. By controlling the movement trajectory, the flexible contact can further press the piano lid, which can further ensure the insertion is in place and accurate.
