Description

[0001] This application is a divisional application filed on October 29, 2025, with application number 2025115565737, entitled "Assembly process applicable to bonding, flipping, shaping and aligning terminal blocks of display FPC". Technical Field

[0002] This invention belongs to the field of display technology, specifically relating to a flipping and shaping process for the terminal blocks of display FPCs. Background Technology

[0003] The screen display is the main window through which we interact with electronic devices, and the FPC (flexible printed circuit board) and its terminals are like a "neural network" connecting the screen and the motherboard, which is of vital importance.

[0004] Currently, FPC terminal blocks include an outer body for connecting to the screen, an insertion end formed at the end of the outer body, and a reinforcing plate and a communication connector (gold finger) that mates the reinforcing plate with the end of the outer body. The reinforcing plate is movably attached to the outer body. During screen information communication assembly, the FPC terminal blocks need to be flipped towards the back of the screen and aligned before being inserted into the connector on the back. However, in the assembly process, the FPC is first flipped and fixed with tape, then the reinforcing plate at the end of the FPC is attracted by a suction cup, and the FPC is assembled onto the connector under the guidance of a robotic arm. The tape is then removed after assembly. Therefore, the following technical defects exist: 1) Due to the inherent flexibility of FPC, if there is no shaping and alignment operation during the assembly process, even if the assembly is completed, the probability of misalignment or offset of the formed contacts is relatively high (the probability of short circuit or open circuit is relatively high). That is, the probability of incomplete or interrupted information transmission is relatively high, which will affect the normal operation of the screen display. 2) During the flipping process, the reinforcing plate is directly subjected to force. If the movement of the reinforcing plate relative to the epitaxial body is not based on the communication terminal, two extreme working conditions will occur at the resulting position: one is that the epitaxial body is too long, and the other is that the epitaxial body is too short. When the epitaxial body is too long, the FPC terminal is stretched or deformed, which will cause damage to the internal circuit and result in a high probability of open circuit. When the epitaxial body is too short, the communication terminal (gold finger) will not be able to properly connect with the connector. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a novel flipping and shaping process for the terminal blocks of FPC displays.

[0006] To achieve the above objectives, the present invention adopts the following solution: A flipping and shaping process for FPC terminal blocks used in screen displays is disclosed. The FPC terminal blocks include an epitaxial body connecting to the screen and an insertion end formed at the end of the epitaxial body. The insertion end includes a reinforcing plate and a communication terminal that mates the reinforcing plate with the end of the epitaxial body. The reinforcing plate is movably attached to the epitaxial body. The equipment used in the process includes a screen positioning mechanism, a flipping mechanism, and a shaping mechanism. The screen positioning mechanism includes a positioning base and a positioning platform. The flipping mechanism includes a moving bolt and a power component. The shaping mechanism includes an adsorption component and a aligning component, wherein the aligning force is greater than the adsorption force formed by the adsorption component. The process includes the following steps: S1. Screen display positioning The screen is placed horizontally, and the FPC terminal extends outward from the left side of the screen and tilts upward from the left side to be placed on the positioning platform, with the reinforcing plate located on the left side of the extension body. S2. Flip Based on the left side of the screen, the moving bolt above or through the positioning platform moves to the right to drive the outer body of the FPC terminal to fit the reference and flip to the right. At this time, the reinforcing plate is located above the outer body, the communication end is located on the right end, and it is freely mounted on the back of the screen. S3. Plastic Surgery The adsorption component acts on the reinforcing plate and lifts it upward to relatively open the reinforcing plate. At the same time, as the adsorption component moves, the epitaxial body tilts and straightens upward from the bonding part. The aligning component, which moves in the width direction of the epitaxial body, synchronously and collaboratively taps the sides of the epitaxial body and the reinforcing plate on the same side to perform centering adjustment so that the right section of the epitaxial body is raised and in a diagonal and flattened state. Meanwhile, the reinforcing plate and the epitaxial body remain relatively open with the communication end as the reference, and the reinforcing plate and the communication end are in a horizontal state to calibrate the state and position of the right end of the communication end.

[0007] Preferably, an upward-facing positioning groove is formed on the positioning base, and the positioning platform is located on the left side of the positioning groove. In step S1, the screen is placed horizontally in the positioning groove with its back facing upward, and the FPC wiring terminals are placed on the positioning platform.

[0008] According to a specific embodiment and preferred aspect of the invention, a notch is formed on the positioning platform, and in step S2, the movable bolt penetrates the interior of the positioning platform and drives the extension body to flip to the right based on the horizontal pushing of the movable bolt.

[0009] Preferably, the head of the movable pin has a rounded corner to avoid contact that could damage the epitaxial body.

[0010] According to another specific embodiment and preferred aspect of the present invention, the bottom surface of the movable plug head is flush with the back surface of the left side portion of the display screen. In the shaping step S3, the extension body is pressed flat between the plug head and the back surface of the display screen from the bonding end. Based on the reference formed by bonding, the posture adjustment of the communication terminal is achieved by traction shaping and alignment at the other end.

[0011] In some specific embodiments, the adsorption assembly includes a negative pressure adsorption head, an adsorption tube, and a negative pressure source; the alignment assembly includes alignment end plates located on both sides and an alignment power unit, wherein the side alignment based on the alignment end plates forms a centering adjustment.

[0012] Since negative pressure adsorption will not damage the reinforcing plate, while maintaining adsorption, the position and angle of the communication end are adjusted by aligning, and the epitaxial body will not be stretched or deformed. In addition, aligning is achieved by simultaneously tapping the sides of the epitaxial body and the reinforcing plate on the same side for centering adjustment.

[0013] According to another specific embodiment and preferred aspect of the invention, the device further includes a wedging mechanism, which includes a wedge head and a wedging power unit. The angle of the wedging end of the wedge head is smaller than the included angle between the reinforcing plate and the epitaxial body. After step S3, as the wedge head is wedged in, and in conjunction with the adsorption assembly, the wedge head, parallel to the communication end, is wedged into the reinforcing plate and abuts against the reinforcing plate and the epitaxial body. This wedging, based on the L-shaped wedging module, reduces the rate of change in the communication end's position caused by the wedging.

[0014] Preferably, the wedge includes an L-shaped wedge module, which comprises a horizontal block and a vertical block. The top surface of the horizontal block contacts the reinforcing plate to form an anti-slip section, and the wedge end of the horizontal block abuts against the inner side of the communication terminal. This anti-slip design not only eliminates deformation or displacement caused by wedge insertion but also facilitates smoother subsequent assembly. The inner contact ensures that the reinforcing plate and the communication terminal are flush, providing the necessary conditions for flat insertion.

[0015] In some specific embodiments, the anti-slip section is an inwardly recessed anti-slip groove; or, the anti-slip section is an anti-slip body protruding from the surface. The anti-slip method is not limited, but the resulting contact surface must be planar.

[0016] Furthermore, the adsorption component, the alignment component, and the wedge are mounted on the same frame. The robot arm docks with the frame, and as the wedge is inserted, the alignment component opens relatively to create a movement avoidance. In short, after the shaping is completed, the wedge further reinforces the horizontal posture of the reinforcing plate and the communication terminal, and while maintaining this posture, the robot arm completes the assembly by shifting and inserting the components.

[0017] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: In the current assembly process of FPC wiring terminals for display screens, due to the inherent flexibility of the FPC, if shaping and alignment operations are not performed during assembly, even if assembly is completed, the probability of misalignment or displacement of the formed contacts is relatively high (leading to a higher probability of short circuits or open circuits). This means a higher probability of incomplete or interrupted information transmission, thus affecting the normal operation of the display screen. Furthermore, during flipping and disassembly, the reinforcing plate is directly subjected to force. If the movement of the reinforcing plate relative to the outer epitaxial layer is not based on the communication terminal, two extreme working conditions may occur: one is that the outer epitaxial layer is too long, and the other... The problems with existing technologies include: a short outer epitaxial layer, which can stretch or deform the FPC terminal block when it's too long, leading to internal circuit damage and a higher probability of open circuits; and a short outer epitaxial layer preventing the communication terminal (gold fingers) from properly aligning with the connector. This invention addresses these shortcomings by providing a comprehensive design for the flipping and shaping process of the FPC terminal block in display screens, cleverly resolving these deficiencies. Using this assembly process, the display screen is first placed horizontally. The FPC terminal block extends from the left side of the display screen and is then tilted upwards and placed on the positioning platform, with the reinforcing plate positioned on the outside. First, based on the left side of the display screen, the moving bolt above or through the positioning platform moves to the right to drive the outer extension of the FPC terminal to fit the reference and flip to the right. At this time, the reinforcing plate is located above the outer extension, the communication end is located on the right end, and it is freely mounted on the back of the display screen. Finally, based on the action of the adsorption component on the reinforcing plate, it is lifted upward to relatively lift the reinforcing plate. At the same time, as the adsorption component moves, the outer extension is tilted upward from the fitting part and straightened. The aligning component, which moves in the width direction of the outer extension, synchronously and cooperatively taps the sides of the outer extension and the reinforcing plate on the same side to perform centering adjustment. The right section of the epitaxial body is raised and in a state of inclined support and flattening. At the same time, the reinforcing plate and the epitaxial body are kept relatively open with the communication end as the reference, and the reinforcing plate and the communication end are in a horizontal state to calibrate the state and position of the right end of the communication end. Therefore, compared with the prior art, this invention is based on a series of coordinated operations of bonding, flipping, adsorption and alignment. Under the premise that the epitaxial body is straightened by tilting upward from the bonding part, the position and angle of the communication end are adjusted. This not only avoids the pulling deformation of the epitaxial body and reduces the probability of damage to the internal circuit of the FPC terminal, but also reduces the risk of short circuit and open circuit caused by contact misalignment and offset.

[0024] like Figures 1 to 5 As shown, the assembly process applicable to the bonding, flipping, shaping and alignment of the terminal blocks of the display FPC involved in this embodiment uses assembly equipment including a display positioning mechanism 1, a flipping mechanism 2, a shaping mechanism 3 and an insertion mechanism 4, wherein the shaping mechanism 3 and the insertion mechanism 4 are mounted on the same robot motion arm S and can move arbitrarily in three-dimensional coordinates.

[0025] Specifically, the FPC terminal block Q includes an outer body q1 for connecting the screen and an insertion end q2 formed at the end of the outer body q1. The insertion end q2 includes a reinforcing plate q20 and a communication terminal q21 (gold finger) that mates the reinforcing plate q20 with the end of the outer body q2. The reinforcing plate q20 is movably attached to the outer body q1. During the screen information communication assembly, the FPC terminal block Q needs to be flipped toward the back of the screen and aligned and inserted into the connector W on the back.

[0026] In this example, the screen display positioning mechanism 1 includes a positioning base 10 and a positioning platform 11. The positioning base 10 forms an upward-facing positioning groove 100. The screen display M is placed horizontally in the positioning groove 100 with its back facing upward. The positioning platform 11 is located to the left of the positioning groove 100, and a notch is formed on the positioning platform 11.

[0027] The flipping mechanism 2 includes a movable pin 20 and a power component 21. The movable pin 20 is horizontally positioned, and the power component 21 drives the movable pin 20 to move in the left-right direction, enabling it to pass through the notch. The pin head 200 of the movable pin 20 has a rounded corner to avoid contact and damage to the outer layer.

[0028] The shaping mechanism 3 includes an adsorption component 30 and a aligning component 31. The adsorption component 30 includes a negative pressure adsorption head 300, an adsorption tube 301, and a negative pressure source. The aligning component 31 includes aligning end plates 310 located on both sides and an aligning power unit 311. Alignment is achieved by aligning the sides of the aligning end plates 310. The resulting aligning force is greater than the adsorption force generated by the adsorption component 30. This force facilitates aligning. The aligning is achieved by tapping the sides of the epitaxial body q1 and the reinforcing plate q20 to achieve alignment. At this time, aligning is achieved by simultaneously tapping the sides of the epitaxial body and the reinforcing plate on the same side for centering adjustment.

[0029] The insertion mechanism 4 includes a wedge 40 and a wedge drive 41, wherein the wedge drive 41 is movable in the up-down and left-right directions to adjust the position of the wedge 40. The wedge 40 includes an L-shaped wedge module 400, wherein movement of the L-shaped wedge module 400 forms a horizontal insertion. The close-fitting wedge formed by the L-shaped wedge module reduces the rate of change in the communication end position caused by the wedge. The L-shaped wedge module 400 includes a horizontal block a and a vertical block b, wherein the top surface of the horizontal block a is flat. This flat fit improves the flat insertion quality. The contact portion between the top surface of the horizontal block a and the reinforcing plate q20 forms an anti-slip section h. Based on the anti-slip, not only is the deformation or displacement caused by the wedge eliminated, but the flat insertion is also performed more smoothly. In some specific embodiments, the anti-slip section is an anti-slip groove recessed from the surface; or, the anti-slip section is an anti-slip body protruding from the surface. The anti-slip method is not limited, but the contact surface formed need to be flat.

[0030] Specifically, the assembly process in this embodiment includes the following steps: S1. Screen display positioning The display screen M is placed horizontally. The FPC terminal Q extends from the left side of the display screen M and tilts upward from the left side and rests on the positioning platform 11. The reinforcing plate q20 is located on the left side of the extension body q1. Meanwhile, the connector W is arranged on the left side of the back of the display screen M with the insertion interface facing left. S2. FPC terminal block flipping Based on the left side of the display screen M as a reference, the movable bolt 20, which penetrates the notch of the positioning platform 11, moves to the right to drive the outer extension q1 of the FPC terminal Q to fit the reference and flip to the right. At this time, the reinforcing plate q20 is located above the outer extension q1, and the communication terminal q21 is located at the right end and is freely mounted on the back of the display screen. S3. Shaping of FPC terminals The self-adhesive end of the epitaxial body q1 is kept relatively flat between the plug head 200 and the back of the display screen. Based on the adsorption component 30 acting on the reinforcing plate q20, it is lifted upward to relatively lift the reinforcing plate q20. At the same time, as the adsorption component 30 moves, the self-adhesive part of the epitaxial body q1 is tilted upward and straightened. The alignment component 31, which moves in the width direction of the epitaxial body q1, performs synchronous alignment, so that the right section of the epitaxial body q1 is raised and in a state of oblique support and flattening. Meanwhile, the reinforcing plate q20 and the epitaxial body q1 are kept relatively open with the communication end head q21 as the reference, and the reinforcing plate q20 and the communication end head q21 are in a horizontal state. S4. FPC terminal block insertion A wedge 40, parallel to the communication head q21, is inserted into and abuts against the reinforcing plate q20 and the epitaxial body q1. The angle of the wedge 40 at the insertion end is less than the included angle between the reinforcing plate q20 and the epitaxial body q1. Under the conditions that the wedge 40 and the epitaxial body q1 are separated, the wedge end of the horizontal block a abuts against the communication head q21, and the epitaxial body q1 is relatively flattened between the plug head 200 and the back of the display screen, the wedge 40, the adsorption component 30, and the alignment component 31 move synchronously downward and to the right to align the communication head q21 with the connector W's insertion interface. Then, the communication head q21 is horizontally inserted to the right into the insertion interface, and the distance of the horizontal insertion and rightward movement is equal to the length of the communication head q21.

[0031] Furthermore, the adsorption assembly 30 and the alignment assembly 31 cooperate to calibrate the state and position of the right-end communication terminal. In short, while maintaining adsorption, alignment is used to adjust the position and angle of the communication terminal without causing stretching or deformation of the epitaxial body. In step S4, during the flat insertion of the communication terminal q21, the mating end of the epitaxial body q1 is pressed against the back side based on the moving pin, and the insertion interface of the connector W is located above and to the side of the mating end. The epitaxial body q1 is tilted upwards from the right end and straightened and positioned between the mating end and the insertion end. Based on the mating of both ends and the flattening of the middle, information docking and transmission are achieved while maintaining a stable posture.

[0032] Simultaneously, the adsorption component 30, the alignment component 31, and the wedge head 40 are mounted on the same frame. The robot arm S docks with the frame. During the insertion process, the alignment component 31 opens relatively to create movement avoidance. As the wedge head 40 fits in, it works with the adsorption component 30 to further stabilize the horizontal posture of the reinforcing plate q20 and the communication terminal q21. Assembly is completed through the displacement and insertion of the robot arm S. In short, after shaping, the wedge head 40 further strengthens the horizontal posture of the reinforcing plate q20 and the communication terminal q21, and while maintaining this posture, assembly is completed by the displacement and insertion of the robot arm S.

[0033] In summary, after adopting this assembly process, firstly, the display screen is placed horizontally. The FPC terminal block extends outward from the left side of the display screen and tilts upward from the left side to rest on the positioning platform, with the reinforcing plate located on the left side of the extension body. Simultaneously, the connector is positioned on the left side of the back of the display screen with its insertion interface facing left. Next, based on the left side of the display screen as a reference, the moving bolt above or through the positioning platform moves to the right, driving the extension body of the FPC terminal block to adhere to the reference and flip to the right. At this time, the reinforcing plate is located above the extension body, the communication terminal is located on the right end, and freely rests on the back of the display screen. Then, based on the action of the adsorption component on the reinforcing plate, it is lifted upward to relatively lift the reinforcing plate. At the same time, as the adsorption component moves, the extension body tilts upward from the adhering part. The outer epitaxial body is aligned and synchronously aligned by a aligning component that moves along its width, ensuring that the raised right section of the epitaxial body is in a braced and flattened state. Simultaneously, the reinforcing plate and the epitaxial body remain relatively open with the communication end as a reference, and both are horizontal. Finally, a wedge parallel to the communication end is inserted into the reinforcing plate and abuts against the reinforcing plate and the epitaxial body. The angle of the wedge insertion end is smaller than the angle between the reinforcing plate and the epitaxial body. Based on the synchronous downward and rightward movement of the wedge, adsorption component, and aligning component, the communication end is aligned with the connector's insertion interface. Then, the communication end is horizontally inserted into the insertion interface to the right. Therefore, compared to existing technologies, this invention, on the one hand, is based on a bonding flip and adsorption alignment process. The coordinated operation of the body and the wedge insertion systematically eliminates the uncertainties in traditional assembly. It not only prevents pulling on the outer body, reducing the probability of damage to the internal wiring of the FPC terminals, but also reduces the risk of short circuits and open circuits caused by contact misalignment or offset. Furthermore, based on the wedge insertion and maintaining the wedge head separated from the outer body, it avoids displacement of the communication terminal caused by movement. Simultaneously, the flat insertion effectively avoids physical damage to terminals and interfaces caused by incorrect angles or uneven force. In addition, it not only makes signal transmission more stable and reliable, but also lays a solid foundation for the normal operation of the display. Thirdly, the rounded corners of the movable pin head prevent damage to the outer body from contact, and the shaping and insertion processes... The epitaxial body is flattened between the plug head and the back side by pressing the bonding end. Based on the reference formed by bonding, the posture of the communication end is adjusted by traction shaping and alignment at the other end. Fourthly, the adsorption component and the alignment component cooperate to calibrate the state and position of the right end of the communication end. In short, while maintaining adsorption, the position and angle of the communication end are adjusted by alignment, without causing the epitaxial body to be stretched or deformed. At the same time, the alignment force is greater than the adsorption force formed by the adsorption component. Under this force, it is easy to implement the alignment. Furthermore, the alignment is formed by tapping the sides of the epitaxial body and the reinforcing plate to form alignment. At this time, the alignment is achieved by simultaneously tapping the sides of the epitaxial body and the reinforcing plate on the same side to make centering adjustment.Fifthly, the L-shaped wedge module creates a snug fit, reducing the rate of change in the communication terminal position caused by the wedge. Furthermore, the top surface of the horizontal block of the L-shaped wedge module is flat, resulting in a smooth fit and improved insertion quality. Simultaneously, the contact area between the top surface of the horizontal block and the reinforcing plate forms an anti-slip section. This anti-slip design not only eliminates deformation or displacement caused by the wedge but also ensures a smoother insertion. The anti-slip section can be a recessed anti-slip groove from the surface; alternatively, it can be a protruding anti-slip body from the surface. The anti-slip method is not limited, but the contact surface must be flat. Sixthly, during insertion, the wedge end of the horizontal block abuts against the inside of the communication head. This inner abutment ensures the reinforcing plate and communication head are flush, providing the necessary conditions for flat insertion. Furthermore, during flat insertion of the communication head, the contact end of the epitaxial member is pressed against the back side by a moving pin. The connector's insertion interface is located above and to the side of the contact end. The epitaxial member tilts upwards from the right end and is straightened and positioned between the contact end and the insertion end. Based on the mating of both ends and the flattening of the middle, information connection and transmission are achieved while maintaining a stable posture. Additionally, the distance the flat insertion moves to the right is equal to the length of the communication head. This avoids over-insertion or incomplete insertion.

They should not be construed as limiting the scope of protection of the present invention.
