Description

Technical Field

[0001] This utility model relates to the field of electronic display module technology, and in particular to an FPC reversing machine. Background Technology

[0002] In the manufacturing process of electronic displays, the FPC (Flexible Printed Circuit) is a key component connecting the display screen and the backlight panel, and its installation quality plays a decisive role in the electrical performance and stability of the product. Folding one end of the FPC back onto the backlight panel and securing it securely is a crucial step in the production process.

[0003] Existing FPC folding machines typically include a pressure-holding mechanism after the FPC folding process. This mechanism applies pressure to ensure the adhesive works effectively, enhancing the bond between the FPC and the backlight panel and ensuring a secure fixation. However, in actual production applications, excessive pressure applied by the pressure-holding mechanism can easily lead to problems such as broken or short-circuited conductive lines inside the FPC, or cause indentations or damage to the FPC surface, affecting its electrical performance and appearance.

[0055] Please refer to Figures 1 to 5 This utility model provides an FPC reversal machine 100, including a frame 200, a feeding module 210, a film-tearing module 220, a reversal module 230, and a discharging module 240; the feeding module 210 is disposed on the frame 200; the film-tearing module 220 is disposed on the opposite side of the feeding module 210, including a film-tearing platform 221 and a film-tearing mechanism 222, the film-tearing mechanism 222 being movable relative to the film-tearing platform 221; the reversal module 230 is disposed on one side of the film-tearing module 220, including a reversal mechanism 231 and a material-applying mechanism 232, the material-applying mechanism 232 including an auxiliary material supply component 233, an auxiliary material conveying component 234, and an auxiliary material pasting component 235; the discharging module 240 is disposed on one side of the feeding module 210.

[0056] The main function of the frame 200 is to install and fix other modules, enabling them to operate under stable conditions. The frame 200 can be made of aluminum alloy or steel, as long as it has sufficient strength and rigidity to withstand the mechanical loads during operation. This utility model does not impose any restrictions on this.

[0057] Please refer to Figure 1 In this embodiment, in order to protect the various modules on the rack 200, a housing 300 is also provided on the rack 200. The material of the housing 300 can be consistent with that of the rack 200. The specific material can be determined according to actual needs, and this utility model does not impose any restrictions here.

[0058] The main function of the feeding module 210 is to place the display module to be processed at the designated work station and provide the initial material for subsequent processes.

[0059] The main function of the film-peeling module 220 is to remove the adhesive release film from the backlight panel of the display module, preparing it for subsequent folding and pasting of auxiliary materials. The film-peeling platform 221 is used to hold the materials, facilitating the film-peeling mechanism 222 to peel off the release film.

[0060] The function of the folding module 230 is to fold the FPC onto the backlight panel and fix it with auxiliary materials (such as tape). Specifically, the folding mechanism 231 folds the FPC onto the backlight panel through mechanical action and initially positions it; the material attaching mechanism 232 attaches the auxiliary materials to the backlight panel to fix the FPC, and then the unloading module 240 unloads the FPC.

[0061] In this embodiment, the auxiliary material supply component 233 can be a storage roll of auxiliary materials (such as tape roll), supporting automatic unwinding and tension control. The auxiliary material conveying component 234 transports the auxiliary materials to a designated position via rollers and a conveyor belt, so that the auxiliary material pasting component 235 can accurately paste the auxiliary materials onto the designated area of ​​the backlight panel to complete the FPC fixation.

[0062] In this embodiment, the robotic arm in the preceding process places the display module on the loading module 210. The display module is then conveyed to the film-peeling platform 221 of the film-peeling module 220, where the film-peeling mechanism 222 peels off the release film at a uniform speed. After film peeling, the material is conveyed to the reversing module 230, where the reversing mechanism 231 folds the FPC onto the backlight panel, completing the initial reversing process. The auxiliary material supply component 233 of the material-applying mechanism 232 releases auxiliary material, the auxiliary material conveying component 234 transports the auxiliary material to a designated position, and then the auxiliary material pasting component 235 pastes the auxiliary material onto the backlight panel, covering the reversing area of ​​the FPC and achieving fixation. The completed display module is then conveyed to the next process by the unloading module 240.

[0063] This embodiment ensures the consistency of the FPC's folding angle and position by setting up the feeding module 210 and the folding mechanism 231, avoiding deviations caused by manual operation. The material pasting mechanism 232 fixes the FPC by pasting auxiliary materials, avoiding damage to the FPC circuitry caused by traditional heavy pressure processes, which is especially suitable for ultra-thin or high-density FPCs.

[0064] Please refer to Figure 5 The auxiliary material pasting assembly 235 includes a pasting bracket 2351, a pasting robot 2353, and a pasting drive component. The pasting bracket 2351 is located on the opposite side of the unloading module 240 and has a first guide rail 2352. The pasting robot 2353 is movably mounted on the first guide rail 2352. The pasting drive component is electrically connected to the pasting robot 2353 and includes a pasting Y-axis drive motor for driving the pasting robot 2353 to move up and down and a pasting X-axis drive motor for driving the pasting robot 2353 to move horizontally.

[0065] The function of the placement bracket 2351 is to serve as a support structure for the placement robot 2353. It is fixed on the frame 200 and equipped with the first guide rail 2352 to ensure the stability and motion accuracy of the placement robot 2353. The material of the placement bracket 2351 can be made of high-strength metal (such as aluminum alloy or steel) to ensure rigidity and resistance to deformation. This utility model does not impose any restrictions on this.

[0066] The first guide rail 2352 can be a linear guide rail, used to constrain the movement trajectory of the material-applying robot 2353, reduce friction and improve positioning accuracy.

[0067] The function of the material-applying robot 2353 is to perform the application of auxiliary materials to fix the FPC. Under the control of the material-applying Y-axis drive motor, the material-applying robot 2353 can rise and fall to pick up the auxiliary materials and contact the application surface of the backlight panel; driven by the material-applying X-axis drive motor, it moves horizontally and repeatedly from the auxiliary material supply position to the auxiliary material application position to fix the FPC, and after applying the auxiliary materials, it returns to the auxiliary material supply position to wait for the next auxiliary material.

[0068] This invention utilizes a dual-axis drive system with independent X / Y axis control, improving positioning accuracy and repeatability, and enhancing the consistency of the pasting position. Furthermore, driven by the Y-axis and X-axis motors, the 2353 pasting robot can respond quickly, increasing pasting efficiency.

[0069] Please refer to Figure 2 and Figure 6 The feeding module 210 includes a second guide rail 211, a feeding platform 212, and a feeding drive. The second guide rail 211 is arranged parallel to the film-tearing module 220 and the folding module 230 on the frame 200. The feeding platform 212 is movably disposed on the second guide rail 211 near the end of the film-tearing module 220. The feeding drive is disposed on the second guide rail 211 near the end of the feeding platform 212.

[0070] The function of the second guide rail 211 is to serve as a guide and support component for the movement of the loading platform 212, providing a precise movement trajectory for the loading platform 212 and ensuring the stability and accuracy of the loading process. The second guide rail 211 can be a linear guide rail, and the material can be a high-hardness metal, such as stainless steel or alloy steel; this utility model does not impose any limitations on this.

[0071] The function of the loading platform 212 is to carry the display module to be processed, move on the second guide rail 211, and accurately transport the material to the subsequent work station.

[0072] The function of the feeding drive is to provide power for the movement of the feeding table 212, realize precise displacement control of the feeding table 212, and ensure that the feeding rhythm matches the subsequent processes. The feeding drive can be composed of a servo motor and a belt, as long as it can realize the linear movement of the feeding table 212, this utility model does not impose any restrictions.

[0073] Please continue to refer to this. Figure 2 and Figure 6 The unloading module 240 includes an unloading platform 241 and an unloading drive component. The unloading platform 241 is movably disposed on one end of the second guide rail 211 near the anti-folding module 230. The unloading drive component is disposed on one end of the second guide rail 211 near the unloading platform 241.

[0074] The function of the unloading table 241 is to receive the products that have completed the folding and pasting process, and to move and transport them to the next process on the second guide rail 211.

[0075] The function of the unloading drive is to provide power for the movement of the unloading table 241, realize precise displacement control of the unloading table 241, and ensure that the unloading rhythm matches the reverse folding process. The unloading drive can be a motor, as long as it can achieve linear movement of the unloading table 241; this utility model does not impose any limitations on this.

[0076] Please refer to Figure 2 and Figure 7 The FPC reversing machine 100 also includes a flipping module 250, which is located between the loading table 212 and the unloading table 241. The flipping module 250 includes two flipping components 251 spaced apart on the side of the second guide rail 211 facing away from the film-tearing module 220. Each flipping component 251 includes a flipping bracket 2511 and a flipping robot 2512 rotatably connected to the flipping bracket 2511.

[0077] When the display module is being loaded, the screen may be facing upwards. The flip module 250 can receive signals from the previous process and automatically flip the backlight panel upwards. There are two sets of flip components 251. One set of flip components 251 connects to the display module on the loading table 212, and the other set of flip components 251 connects to the display module after the FPC is folded up, flipping it and handing it over to the unloading table 241 for unloading.

[0078] In this embodiment, the flipping bracket 2511 mainly serves as the support structure for the flipping robot 2512. It can be made of high-strength metal materials (such as aluminum alloy or steel) to ensure stability during the flipping process and prevent shaking or deformation. This utility model does not impose any limitations on this.

[0079] The flipping robot 2512 is rotatably connected to the flipping bracket 2511. Flexible rotation can be achieved using a rotating shaft and bearings; however, this invention does not impose any limitations on this. The flipping robot 2512 rotates to flip the display module, ensuring the backlight panel always enters subsequent processes in the correct posture. This avoids the problem of FPC folding failure due to incorrect material posture, thereby effectively improving product processing accuracy and reducing the defect rate.

[0080] Please refer to Figure 2 and Figure 8 The FPC reversing machine 100 also includes a transfer module 260, which is located between the film tearing module 220 and the reversing module 230. The transfer module 260 includes a gantry frame 261 spanning the second guide rail 211. The transfer module 260 also includes two transfer components 262 located on opposite sides of the gantry frame 261. Each transfer component 262 includes a transfer guide rail 2621 located on the crossbeam of the gantry frame 261 and a transfer robot 2622 movably located on the transfer guide rail 2621.

[0081] The transfer guide rail 2621 is mounted on the crossbeam of the gantry 261. A high-precision linear guide rail can be used, and this utility model does not impose any restrictions on its use. By setting the transfer guide rail 2621, the transfer robot 2622 can be ensured to move smoothly and accurately in the horizontal direction.

[0082] The transfer robot 2622 is movably mounted on the transfer guide rail 2621 and can move horizontally and vertically relative to the frame 200. For example, it can move the display module to different workstations by moving horizontally, and pick up and release the display module by moving vertically.

[0083] This embodiment is provided with two sets of transfer components 262. One set of transfer components 262 moves along the transfer guide rail 2621 on the same side to the top of the flipping module 250, and descends to pick up the flipped display module. Then, the robot arm transports the material along the transfer guide rail 2621 to the top of the film-tearing platform 221 of the film-tearing module 220 and places it accurately. The film-tearing module 220 then begins the release film removal operation.

[0084] After the film-peeling process is completed, another set of transfer components 262 picks up the film-peeled material and transports it to the anti-folding module 230 station, placing it in the designated position of the anti-folding mechanism 231. The anti-folding module 230 performs anti-folding and material-fixing operations on the FPC. After the anti-folding process is completed, the transfer component 262 starts again, picks up the anti-folded material, and transports it back to the flipping module 250. After the flipping module 250 performs a second flipping adjustment on the material, the unloading platform 241 receives the material and transports it to the discharge area, completing the entire production process.

[0085] This utility model is equipped with two sets of transfer components 262, which work in parallel to realize the synchronous handling of materials from the flipping module 250 to the film-tearing module 220, from the film-tearing module 220 to the anti-folding module 230, and from the anti-folding module 230 to the flipping module 250. This reduces the waiting time of individual materials between processes and effectively improves the overall production cycle of the equipment.

[0086] Please refer to Figure 3 and Figure 4 The film-tearing module 220 also includes a third guide rail 223, which is arranged parallel to the second guide rail 211 on the frame 200; the film-tearing platform 221 is movably disposed on the side of the third guide rail 223 near the film-tearing mechanism 222; wherein, the film-tearing mechanism 222 includes a film-tearing bracket 2221 and a film-tearing guide rail 2222 disposed on the film-tearing bracket 2221, and the film-tearing guide rail 2222 is movably connected to the film-tearing robot arm 2223.

[0087] The function of the third guide rail 223 is to provide guidance and support for the linear motion of the film-tearing platform 221, ensuring the positional accuracy of the film-tearing platform 221 during material receiving, film tearing, and material transfer. The third guide rail 223 is arranged parallel to the second guide rail 211, so that the movement path of the film-tearing platform 221 coordinates with the material transfer path of the feeding and transfer module 260, reducing spatial interference. The third guide rail 223 can be a linear guide rail, as long as it enables the linear motion of the film-tearing platform 221; this invention does not impose any limitations on this.

[0088] The film-tearing bracket 2221 serves as a support structure for the film-tearing guide rail 2222 and the film-tearing robot 2223. It can be made of aluminum alloy profiles or welded steel plates, and it only needs to have sufficient rigidity to reduce vibration during the movement. This utility model does not impose any restrictions on this.

[0089] The film-peeling platform 221 moves along the third guide rail 223 to the receiving position below the transfer component 262. The transfer robot 2622 places the material on the film-peeling platform 221, and the film-peeling platform 221 carries the material back to the film-peeling working position. The film-peeling robot 2223 moves along the film-peeling guide rail 2222 to the position of the adhesive paper on the backlight panel, and mechanically removes the release film. After film peeling is completed, the film-peeling platform 221 moves again along the third guide rail 223 to below the transfer component 262. The transfer robot 2622 picks up the peeled material and transfers it to the folding module 230 for further processing.

[0090] This invention, by incorporating a third guide rail 223, ensures that the film-tearing platform 221 automatically picks up and transports materials, thus improving efficiency. Furthermore, the rapid film-tearing by the robotic arm 2223 avoids repeated manual operations that could damage the FPC or leave release film residue, thereby improving product yield.

[0091] In some embodiments, the film-tearing module 220 further includes a film-tearing drive component, which is disposed on the film-tearing bracket 2221 and electrically connected to the film-tearing robot 2223. The film-tearing drive component includes a film-tearing Y-axis drive motor for driving the film-tearing robot 2223 to move up and down and a film-tearing X-axis motor for driving the film-tearing robot 2223 to move horizontally. The film-tearing drive component also includes a film-tearing rotary motor for driving the film-tearing robot 2223 to rotate. A waste collection device 2224 is disposed between the film-tearing mechanism 222 and the film-tearing platform 221 for recycling the torn release film.

[0092] In this embodiment, the film-peeling robot 2223 picks up the auxiliary adhesive paper, which can adhere to the release film of the backlight panel and easily peel it off.

[0093] Once the film-peeling platform 221 carries the material to the designated position, the film-peeling Y-axis drive motor drives the film-peeling robot 2223 to descend, bringing it close to the edge of the adhesive tape and attaching the auxiliary adhesive tape to the release film. The film-peeling rotary motor drives the film-peeling robot 2223 to swing, peeling off the release film and placing the auxiliary adhesive tape and release film together into the waste collection device 2224. Afterwards, the film-peeling Y-axis drive motor drives the film-peeling robot 2223 to rise and reset, and the film-peeling X-axis drive motor drives the film-peeling robot 2223 to pick up new auxiliary adhesive tape before returning to the film-peeling position to await the next display module.

[0094] This invention utilizes a three-axis linkage design in the film-tearing drive component, enabling the film-tearing robot 2223 to perform film-tearing actions more flexibly. It can quickly and completely tear off even complex-shaped or highly adhesive films, significantly improving film-tearing efficiency. Furthermore, the entire process from film tearing to waste collection requires no manual intervention, reducing the uncertainty and errors caused by manual operation, increasing the automation level of the production process, and lowering labor costs.

[0095] Please refer to Figure 3 and Figure 5 The anti-folding mechanism 231 includes an anti-folding platform 2311 and an anti-folding component 2312. The anti-folding platform 2311 is movably located on the side of the third guide rail 223 near the material application mechanism 232. The anti-folding component 2312 is rotatably connected to the anti-folding platform 2311.

[0096] The folding platform 2311 serves as the basic working surface for FPC folding and is movably mounted on the side of the third guide rail 223 near the material application mechanism 232. The folding platform 2311 can move linearly along the third guide rail 223, achieving efficient docking with the transfer module 260, the folding mechanism 231, and the material application mechanism 232.

[0097] The folding member 2312 can be an I-shaped, L-shaped, or Z-shaped robotic arm structure. For example, the folding member 2312 is an I-shaped double robotic arm that can fold the FPC onto the backlight panel through its own rotation. Of course, the above is only an example, and the specific shape and structure can be determined according to actual needs. This utility model does not impose any limitations on this.

[0098] The transfer component 262 places the screen display module, after the film has been removed, onto the reversing platform 2311. The reversing platform 2311 receives the screen display module and transports it to the reversing station. The reversing component 2312 folds the FPC onto the backlight panel, and the adhesive tape on the backlight panel provides initial fixation for the FPC. After the material application mechanism 232 further fixes the FPC with auxiliary materials, the reversing platform 2311 transports the screen display module to the transfer component 262, which then transports it to the subsequent station.

[0099] The cooperation between the folding platform 2311 and the third guide rail 223 in this invention enables rapid material transport and positioning. The high-speed rotation and precise movement of the folding component 2312 significantly shorten the folding time of a single FPC, meeting the needs of large-scale mass production. In addition, the folding process is fully automated, reducing manual intervention and lowering the risk of operators being pinched or injured by mechanical parts, thus ensuring production safety.

[0100] Please continue to refer to this. Figure 5 The folding module 230 also includes a detection mechanism 236 disposed above the folding platform 2311. The detection mechanism 236 can be a CCD. The backlight panel has alignment lines on its surface. After the folding component 2312 folds the FPC, the CCD camera can capture images and analyze whether the FPC aligns with the alignment lines, thus improving folding accuracy. After confirming FPC alignment, auxiliary materials are then pasted and fixed.
