Description

Technical Field

[0001] This invention belongs to the field of automatic detection technology for display panels, and particularly relates to an automatic FPC disconnection method and device for display panels. Background Technology

[0002] In the production process of automotive displays, the first step is to precisely connect the flexible printed circuit board (FPC) to the display body. This step is crucial for ensuring the proper functioning of the display, as the FPC is responsible for transmitting signals and power, enabling the display to work correctly. However, traditional production methods mainly rely on operators manually disconnecting the FPC wires, a process that is not only inefficient but also costly. Due to differences in operator skill levels and experience, manual wire disconnection can lead to unstable connections between the FPC and the display body, thus affecting the display's performance and reliability. Furthermore, manual wire disconnection can damage the FPC, reducing its recyclability. Therefore, improving the efficiency and accuracy of FPC wire disconnection and reducing damage to the FPC has become an urgent problem to be solved in the production of automotive displays. Summary of the Invention

[0003] To address all or part of the problems in the prior art, this invention provides an automatic wire-pulling method and device for FPC display panels. By integrating four major modules—feeding, wire pulling, storage, and control—automatic wire pulling operations for FPC are achieved.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An automatic FPC disconnection method for a display panel includes the following steps:

[0006] S1. Place the display panel to be processed on the platform of the feeding module, and control the system to instruct the first adsorption mechanism on the linear module to move directly below the connection point of the flexible circuit board, and use adsorption force to fix the flexible circuit board.

[0007] S2. After receiving the command from the control system, the robotic arm moves above the display panel. Under the control command, the elastic opening head of the opening mechanism contacts and pushes open the protective cover above the flexible circuit board, exposing the connection point of the flexible circuit board.

[0008] S3. The vision unit is activated to take pictures and identify the exposed connection points of the flexible circuit board. Based on the feedback provided by the vision unit, the robot arm automatically adjusts to the optimal position so that the suction cup of the second adsorption mechanism is aligned with the flexible circuit board. The drive cylinder receives the command and starts, driving the suction cup to descend and adsorb the flexible circuit board.

[0009] S4. Under the control of the control system, the robot arm separates the flexible circuit board from the display panel and moves the adsorbed flexible circuit board to the top of the storage module. The drive cylinder receives the instruction again and starts to place the flexible circuit board into the empty storage bin. After the material is unloaded, the robot arm and drive cylinder automatically return to their original state and prepare for the next operation.

[0010] This method integrates four modules—feeding, wire pulling, storage, and control—to automate the wire pulling process for flexible circuit boards. This automation not only improves production efficiency but also reduces manual intervention, thereby lowering labor intensity and production costs.

[0011] In step S4, if the drive cylinder malfunctions, causing the suction cup to continue descending without stopping in time, an alarm device is triggered, and the control system immediately stops the drive cylinder from descending. By stopping the descent of the drive cylinder in time, the suction cup is prevented from continuing to apply pressure to the flexible circuit board, thereby reducing the risk of damage to the flexible circuit board and effectively preventing equipment damage or material damage.

[0012] The present invention also provides an automatic wire-removing device for flexible circuit boards of display panels, used to implement the automatic wire-removing method described above, wherein the automatic wire-removing device specifically includes:

[0013] The feeding module includes a platform for supporting and placing the display panel to be processed;

[0014] A wire-pulling module is used to pull out the flexible circuit board on the display panel; it includes a robotic arm, a wire-pulling module, and a vision unit, wherein the wire-pulling module and the vision unit are integrated into the robotic arm;

[0015] A storage module includes at least two storage hoppers and a rotating mechanism. The storage hoppers are mounted on the rotating mechanism, which rotates a full storage hopper to an unloading position and simultaneously rotates an empty storage hopper to a discharge position.

[0016] The control system is responsible for monitoring the operating status of each module and sending control commands to coordinate the movement of the robot arm, the operation of the wire-pulling module, the recognition of the vision unit, and the operation of the rotating device.

[0017] Automated equipment reduces human intervention, making each step of the operation precise and efficient. The coordinated work of robotic arms, vision units, and control systems ensures a fast and accurate wire removal process for flexible circuit boards, thereby improving overall production efficiency.

[0018] The feeding module includes a linear module located below the connection point of the flexible circuit board on the display panel to be processed. Multiple first adsorption mechanisms are installed on the linear module according to the specific layout of the flexible circuit board. These first adsorption mechanisms can move in a preset direction on the linear module to adjust to a suitable position to adsorb the flexible circuit board. Each first adsorption mechanism can independently move to a precise position on the linear module. This point-to-point precision adsorption strategy effectively reduces errors during operation.

[0019] The wire-pulling module includes a cover-opening mechanism and a second adsorption mechanism. The cover-opening mechanism is used to open the protective cover above the flexible circuit board of the display panel, thereby exposing the connection points of the flexible circuit board below. The second adsorption mechanism uses adsorption force to fix the flexible circuit board, and with the operation of the robotic arm, it drives the flexible circuit board to gradually separate from the display panel. This realizes a continuous operation process from opening the protective cover to fixing the flexible circuit board.

[0020] The second adsorption mechanism includes a drive cylinder and a suction cup assembly. The suction cup assembly is mounted on the drive end of the drive cylinder and has multiple suction cups. The drive cylinder, receiving commands from the control system, drives the suction cups to move up and down. Multiple suction cups can simultaneously act on different positions of the flexible circuit board, ensuring the flexible circuit board remains stable during wire removal.

[0021] When the robotic arm performs a wire-pulling operation, the cylinder drives the suction cup to move downwards to above the flexible circuit board for adsorption; when the robotic arm performs a material unloading operation, the drive cylinder drives the suction cup to carry the flexible circuit board downwards to the bottom area of ​​the storage bin for unloading. This reduces the risk of material damage or unloading failure due to positional deviation.

[0022] The second adsorption mechanism also includes an alarm device, specifically a sensor and a flexible limiting rod. The flexible limiting rod is mounted on the suction cup assembly and descends together with the suction cup assembly. The sensor is fixedly mounted directly above the flexible limiting rod. Once the flexible limiting rod touches or approaches the sensor, the sensor will immediately trigger an alarm signal.

[0023] When the suction cup descends with the drive cylinder into the storage hopper and approaches or reaches the preset bottom area, if it continues to descend for any reason, the elastic limit rod will contact the material stored at the bottom of the hopper. At this point, the elastic limit rod will be subjected to upward pressure and move upward until it touches the sensor above. The sensor will immediately send a signal to the control system, which will then control the drive cylinder to stop descending. This prevents damage to the suction cup and drive cylinder due to excessive descent, extends the service life of the equipment, and reduces maintenance costs.

[0024] The opening mechanism includes a mounting base, an opening plate, and a flexible opening head. One side of the mounting base is mounted on the robotic arm, and the other side is provided with a guide rail. One end of the opening plate is slidably mounted in the guide rail via a slider. The flexible opening head is mounted on the other end of the opening plate via an elastic connector, allowing the flexible opening head to slide elastically up and down relative to the opening plate. The opening mechanism adopts a double elastic design, which improves the cushioning effect of the flexible opening head when contacting the protective cover, effectively avoiding damage caused by hard contact.

[0025] The present invention has at least the following beneficial effects:

[0026] 1) By integrating four major modules—material feeding, wire pulling, storage, and control—a highly automated production system has been constructed. From the placement of the display panel and the precise adsorption and extraction of flexible circuit boards to the automatic storage and transfer of materials, the entire process achieves seamless integration and intelligent control, significantly improving production efficiency. Guided by a vision unit, the robotic arm can quickly and accurately identify the connection points of the flexible circuit boards and achieve smooth extraction through the precise adsorption of the second adsorption mechanism. This high-precision and intelligent operation mode reduces operation time and improves production efficiency.

[0027] 2) The cover opening mechanism in the wire-pulling module adopts a double-elastic design, effectively avoiding damage to the protective cover caused by hard contact. Simultaneously, the alarm device in the second adsorption mechanism, through the cooperation of an elastic limit rod and a sensor, prevents excessive descent due to abnormal drive cylinder operation, ensuring operational safety. The control system comprehensively monitors the operating status of each module and monitors potential safety hazards in real time through the alarm device. Once an abnormality is detected, such as abnormal descent of the drive cylinder, the system will immediately issue an alarm and take corresponding emergency measures, effectively preventing the risk of equipment damage or material injury.

Detailed Implementation

[0037] The technical solutions in specific embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] This invention provides a detailed description of an automatic FPC wire disconnection device for display panels, designed to simplify the production process and improve production efficiency. For example... Figures 1-7As shown, the core components of this equipment consist of four main modules: First, the feeding module 1, which is equipped with a material loading platform to support and properly place the display panels to be processed; second, the wire pulling module 4, which, as the key operating unit of the equipment, integrates a robotic arm 201, a wire pulling module 202, and a vision unit 203. This integrated design enables the robotic arm 201, guided by the vision unit 203, to accurately identify and pull out the FPCs on the display panels, achieving high precision and intelligence in operation; third, the storage module 3, which cleverly incorporates at least two storage bins 301 and is equipped with a flexible rotating mechanism 302. The rotating mechanism 302 can automatically rotate the full hopper to a position that is easy to unload according to the full load of the storage hopper 301, and at the same time rotate the empty hopper to the material unloading position of the robot arm 201, realizing seamless connection and efficient management of materials; finally, the control system is used to comprehensively monitor the operating status of each module, and ensure the coordinated operation of the robot arm 201, the wire pulling module 202, the vision unit 203 and the rotating device by accurately sending control commands, thus realizing the efficient and stable operation of the equipment.

[0039] In the feeding module 1, an integrated linear module 101 is specially designed to precisely handle the FPC connection points on the display panel. This linear module 101 is installed below the FPC connection points on the display panel to be processed, ensuring accurate operation. Multiple first adsorption mechanisms 102 are configured on the linear module 101 according to the detailed layout and arrangement characteristics of the FPCs. These adsorption mechanisms not only have adsorption capabilities to firmly grasp the FPCs, but can also move freely along a preset direction under the control of the linear module 101. Through an intelligent adjustment mechanism, the first adsorption mechanism 102 can quickly and accurately move to the optimal position to precisely adsorb the FPCs, providing a stable foundation for subsequent wire removal operations.

[0040] The wire-pulling module 202 integrates the cover-opening mechanism 2021 and the second adsorption mechanism 2022, aiming to achieve precise opening of the protective cover above the FPC connection point on the display panel and stable removal of the FPC. The cover-opening mechanism 2021 specifically includes a mounting base 2021-1, a cover-opening plate 2021-2, and a flexible cover-opening head 2021-3. The mounting base 2021-1 serves as the base of the entire cover-opening mechanism 2021, with one side firmly connected to the robotic arm 201, ensuring the stability of the cover-opening mechanism 2021 during movement. The other side is equipped with a guide rail, providing a guiding path for the sliding of the cover-opening plate 2021-2. One end of the cover-opening plate 2021-2 connects to the guide rail via a slider and slides smoothly, while the other end connects to the flexible cover-opening head 2021-3. This design fully considers various possibilities during the opening of the protective cover, such as inconsistent tightness and positional deviations. The flexible cover opening head 2021-3 is connected to the cover opening plate 2021-2 via elastic components (such as springs or elastic sheets), allowing it to slide elastically in the vertical direction. When the robotic arm 201 positions the cover opening mechanism 2021 at the protective cover above the FPC connection point, the control system issues a command. As the cover opening plate 2021-2 moves, the flexible cover opening head 2021-3, aided by the elastic components, gently contacts the protective cover. Under continued pressure, utilizing its elastic sliding characteristics, it skillfully pushes open the protective cover, thereby exposing the FPC connection point below. This dual elastic design enhances the cushioning effect of the flexible cover opening head 2021-3 when contacting the protective cover, effectively preventing damage caused by hard contact.

[0041] The second adsorption mechanism 2022 is designed to hold the FPC in place using adsorption force and, under the control of the robotic arm 201, smoothly separate the FPC from the display panel and automate the subsequent unloading process. This mechanism integrates a drive cylinder 2022-1 and a suction cup assembly 2022-2. The suction cup assembly 2022-2, acting directly on the FPC, is equipped with multiple evenly distributed suction cups that can uniformly and effectively adsorb the FPC, preventing slippage or damage during wire pulling or movement. The suction cup assembly 2022-2 is mounted on the drive end of the drive cylinder 2022-1. The cylinder's extension and retraction movement moves the suction cups up and down, flexibly adapting to the need to remove FPCs at different heights and positions. To ensure operational safety and reliability, the second adsorption mechanism 2022 also innovatively incorporates an alarm device 2023, which consists of a precision sensor 2023-1 and a flexible limit rod 2023-2. The elastic limit rod 2023-2, a key element of this safety mechanism, comprises a fixed part and a movable part. The fixed part is mounted on the connecting seat of the suction cup assembly 2022-2 and has a hollow internal structure. The fixed part is sleeved with the movable part and is designed to move vertically relative to the fixed part. This design ensures that when the suction cup assembly 2022-2 descends with the drive cylinder 2022-1 to the bottom area of ​​the storage hopper 301, if any abnormality causes it to continue descending, the movable part will contact the bottom of the hopper or the material, triggering the alarm mechanism. At this time, the movable part is subjected to an upward reaction force and moves upward until its top touches the sensor 2023-1 above. Once the sensor 2023-1 receives the signal, it immediately sends an alarm to the control system, which then responds and immediately stops the cylinder's descent, effectively preventing equipment damage or material damage caused by excessive descent.

[0042] Storage module 3 aims to optimize the material storage and transfer process in the production flow. Its core components include two storage bins 301, a rotating mechanism 302, and an auxiliary buffer bin 303. The rotating mechanism 302 consists of a mounting platform 3021 and a power unit 3022 mounted at the bottom center of the mounting platform 3021. The power unit 3022 serves as the power source for rotation, precisely driving the mounting platform 3021 to rotate. The two storage bins 301 are symmetrically mounted at both ends of the mounting platform 3021, ensuring structural balance and stability. Specifically, the layout of these two storage bins 301 is carefully planned: one is always located at the preset material feeding position of the robot arm 201, facilitating material feeding operations; while the other is located at the material picking position of the upstream equipment's wiring robot arm 201, achieving seamless integration of material supply and retrieval. When the storage bin 301 at the preset unloading position of the robotic arm 201 reaches full capacity, the power unit 3022 is activated, driving the mounting platform 3021 to rotate 180° clockwise or counterclockwise. This ensures that the empty storage bin 301 quickly and accurately moves to the unloading position, taking over the work of the full-load bin, thus achieving continuity and efficiency in material storage. This design not only reduces manual intervention but also significantly improves the automation level of the production line. Furthermore, to address material storage needs under special circumstances, this invention creatively introduces a buffer bin 303. When both main storage bins 301 are full, excess material can be temporarily transferred to the buffer bin 303 for storage, effectively preventing production line stagnation caused by material accumulation.

[0043] The display panel FPC wire pulling device of this invention achieves a highly efficient and automated production process by integrating four major modules: feeding, wire pulling, storage, and control. Specifically, the wire pulling module 202 employs a dual-elastic design to effectively prevent damage to the protective cover caused by hard contact; the second adsorption mechanism 2022 incorporates an alarm device 2023 to ensure operational safety and reliability; and the storage module 3, through the design of the rotating mechanism 302 and the buffer hopper 303, achieves continuous and efficient material storage, reducing manual intervention and improving the automation level of the production line. These innovative designs not only simplify the production process and improve production efficiency but also significantly enhance the intelligence and stability of the equipment.

[0044] The present invention also provides an automatic wire disconnection method for an FPC display panel, which is implemented based on the aforementioned automatic wire disconnection device, and the specific steps are as follows:

[0045] S1. Place the display panel to be processed on the platform of the feeding module 1; control the linear module 101 to drive the first adsorption mechanism 102 integrated on it to move directly below the FPC connection point and fix the FPC by adsorption force.

[0046] S2. After receiving the command from the control system, the robotic arm 201 moves to the top of the display panel. The elastic opening head 2021-3 of the opening mechanism 2021 contacts and pushes open the protective cover above the FPC under the control command, thereby exposing the FPC connection point.

[0047] S3. The vision unit 203 is activated to take pictures and identify the exposed FPC connection points. The robot arm 201 automatically adjusts to the optimal position based on the feedback provided by the vision unit 203, so that the suction cup of the second adsorption mechanism 2022 is aligned with the FPC. The drive cylinder 2022-1 receives the command and starts, driving the suction cup to descend and adsorb the FPC.

[0048] S4. Under the control of the control system, the robot arm 201 separates the FPC from the display panel and moves the adsorbed FPC to the top of the storage module 3. The drive cylinder 2022-1 receives the instruction again and starts, placing the FPC in the empty storage bin 301. If the drive cylinder 2022-1 malfunctions, causing the suction cup to continue descending without stopping in time, the alarm device 2023 is triggered, and the control system will immediately control the drive cylinder 2022-1 to stop descending. After the unloading is completed, the robot arm 201 and the drive cylinder 2022-1 automatically return to their original state, ready for the next operation.

[0049] Through the above steps, this invention achieves efficient and automated wire disconnection operation for display panel FPCs, significantly improving production efficiency while ensuring operational safety and reliability.

[0050] It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of this invention.
