Description

Technical Field

[0001] This invention relates to the field of FPC board reinforcement technology, specifically to an intelligent reinforcement device and reinforcement method for FPC boards. Background Technology

[0002] FPC (Flexible Printed Circuit) board reinforcement involves attaching rigid materials (such as polyimide (PI), FR-4 fiberglass board, metal sheets, etc.) to specific areas of the flexible printed circuit board to enhance its mechanical strength, bending resistance, and dimensional stability. This also improves heat dissipation and facilitates assembly and soldering. This process prevents FPC breakage at stress points (such as connectors and chip solder joints) due to frequent bending or external impacts, ensuring signal transmission stability. It is widely used in high-reliability applications such as smartphone camera modules, foldable screen hinges, and automotive electronics.

[0003] CN120358676B discloses an FPC (Flexible Printed Circuit) reinforcing plate bonding machine. The positioning unit includes a double-rail slide horizontally positioned at the top of the machine frame. A movable frame is arranged between the sliders of the double-rail slide, and a mounting frame is mounted on the movable frame. A displacement group is mounted on the movable component of the displacement group, and a distribution frame with at least two built-in winding sections is provided. This achieves fully automated operation from winding, conveying, and stamping of the reinforcing plate film to final bonding onto the FPC board, significantly reducing manual intervention, lowering labor intensity and labor costs, while improving production continuity, process standardization, and adaptability, allowing for more flexible responses to diverse production needs.

[0004] However, as shown in the above technology, existing FPC line reinforcement plate bonding equipment clamps one reinforcement plate at a time and then moves it to the designated position on the FPC line for pressing and bonding. It bonds one at a time, which is inefficient. Some equipment, such as the above technology, even requires manually placing the FPC line on the worktable for positioning before starting the equipment for bonding, which further reduces processing efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an intelligent reinforcement device and method for FPC boards, which solves the problem of low processing efficiency in existing FPC board reinforcement plate bonding equipment.

[0011] Preferably, the unwinding drum drive mechanism includes: A prism shaft is rotatably mounted on a bracket, and a reinforcing plate unwinding drum is sleeved on the prism section of the prism shaft. A baffle is sleeved on one end of the prism shaft and on the side of the reinforcing plate unwinding drum away from the bracket, and a clamp for limiting the baffle is engaged at the end of the prism shaft. A driven gear is fixedly connected to the other end of the prism shaft. A low-speed motor is fixedly connected to the other side of the bracket via a motor frame, and a drive gear that meshes with the driven gear is fixedly connected to the output shaft of the low-speed motor. An infrared sensor switch is fixedly connected to the other side of the bracket and located on the side of the active gear. A light-blocking plate is fixedly connected to the surface of the active gear. The light-blocking plate intermittently blocks the infrared rays of the infrared sensor switch during rotation.

[0012] Preferably, the FPC board bracket includes: The second support plate is used to hold and support the bottom of the FPC strip; The second diagonal brace is fixedly connected to the bottom of the second support plate, and the second diagonal brace and the first diagonal brace are fixed to the bracket together by the same bolts; Sliding dividers are located at the four corners of the top of the second tray to confine the FPC strip between the sliding dividers.

[0013] Preferably, the FPC board bracket further includes: A double-acting lead screw is rotatably connected to the bottom of the second support plate via a bearing seat, and a handwheel is fixedly connected to one end of the double-acting lead screw; Two threaded sleeves are provided, each threadedly connected to the two reverse threads of the bidirectional lead screw; The insert rod is fixedly connected to both sides of the threaded sleeve, and the insert rod extends upward through the second support plate and is inserted into the sliding partition block. The interior of the second support plate is provided with a guide groove that matches the insert rod.

[0014] Preferably, a reinforcing plate take-up drum, multiple first guide roller groups, and a second guide roller group are rotatably connected to both sides of the bracket. The reinforcing plate take-up drum is used to take up the release paper of the reinforcing plate strip after the reinforcing plate is removed, and the multiple first guide roller groups and the second guide roller groups are used to guide the trajectory of the reinforcing plate strip and the FPC strip, respectively. A take-up drum drive motor is fixedly connected to one side of the bracket. The output end of the take-up drum drive motor is connected to the reinforcing plate take-up drum through a pulley assembly, and the output end of the take-up drum drive motor is connected to the drive pulley of the pulley assembly through a torque sensor.

[0015] This invention also discloses a reinforcement method for an intelligent reinforcement device used in FPC boards, comprising the following steps: Step 1: Transfer the FPC strip and the reinforcing strip on both sides of the bracket, and make sure that the FPC strip and the reinforcing strip rest on the FPC board bracket and the reinforcing board bracket respectively. Step 2: Activate the transfer and attachment mechanism, use the first pressure block to press down the sliding negative pressure seat, and extract the air in the sliding negative pressure seat to generate negative pressure to suck up the reinforcing plate on the reinforcing plate belt below. Then raise the first pressure block and lift the sliding negative pressure seat and the reinforcing plate. Step 3: Move the sliding frame and its inner sliding negative pressure seat above the FPC strip by pulling the first push rod. Then, control the third push rod to press down the second pressure block, which in turn presses down the sliding negative pressure seat to simultaneously press multiple different reinforcing plates onto the designated positions on the FPC strip and stick them in place. Then, disconnect the air extraction of the sliding negative pressure seat, raise the second pressure block and the sliding negative pressure seat, and reset the adsorption and transfer mechanism. Then, continue to transfer the FPC strip and reinforcing strip to reinforce the next set of FPC boards.

[0016] This invention provides an intelligent reinforcement device and method for FPC boards. Compared with the prior art, it has the following advantages: 1. This intelligent reinforcement device for FPC boards attaches both the FPC board and reinforcement plates onto paper tapes for simultaneous transport. Multiple reinforcement plates on a single FPC board are attached to different paper tapes. A transfer and attachment mechanism simultaneously picks up and moves these reinforcement plates onto the FPC board, and lowering it completes the simultaneous attachment of multiple reinforcement plates. The transfer and attachment mechanism utilizes a sliding negative pressure seat and a positioning groove to position the sliding negative pressure seat in two locations. Multiple sliding negative pressure seats move independently, evenly distributing multiple rows of reinforcement plates at the loading position, while at the other end, they can be rearranged according to the reinforcement location. The reinforcement location is accurate and efficient, significantly improving efficiency compared to using a robotic arm to clamp and attach each reinforcement plate individually. Furthermore, the transfer and attachment mechanism features a modular design; the gantry frame, first pressure block, second pressure block, and other structures can be replaced as needed, allowing for adjustments based on the reinforcement location of different FPC boards, thus providing versatility.

[0017] 2. This intelligent reinforcement device for FPC boards, by setting a self-tightening suction device, can extract air from the sliding negative pressure seat, creating negative pressure at its bottom to suck up the reinforcement board. Since the sliding negative pressure seat needs to move, to prevent the suction hose from drooping and folding inside the U-shaped frame and affecting the operation, a counterweight ring is fitted on the part of the suction hose located outside the U-shaped frame. When the sliding negative pressure seat moves, the suction hose will extend and retract outside the U-shaped frame, without affecting the processing operation, and is easy to use.

[0018] 3. This intelligent reinforcement device for FPC boards uses a torque sensor to connect the take-up drum drive motor and the pulley assembly that drives the reinforcement plate take-up drum. This allows for real-time monitoring and control of the torque between the take-up drum drive motor and the reinforcement plate take-up drum, ensuring that the reinforcement plate take-up drum maintains a certain tension on the reinforcement plate strip, preventing slack and facilitating the removal of the reinforcement plate from the release paper. The drive mechanism of the reinforcement plate unwinding drum uses a combination of a drive gear and a driven gear to drive a low-speed motor and a prism shaft, achieving intermittent transmission of the reinforcement plate unwinding drum. This allows for intermittent output of the reinforcement plate strip, thus reserving time for attaching the reinforcement plate. Furthermore, a light-blocking plate installed on the drive gear, along with an infrared sensor switch, can detect the number of rotations of the reinforcement plate unwinding drum. This not only facilitates control of the low-speed motor speed but also helps calculate the remaining layers of the reinforcement plate strip, enabling timely reminders for staff to replace the reinforcement plate unwinding drum. This design is quite intelligent.

[0019] 4. This intelligent reinforcement device for FPC boards can separate multiple reinforcement strips by setting positioning dividers on the reinforcement strip bracket, and achieve position positioning. The reinforcement strip unwinding drum can be replaced according to the specifications of the reinforcement strip. The sliding dividers with manually adjustable spacing are set on the FPC board bracket to adapt to FPC strips of different widths, thus improving adaptability. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0023] See Figures 1-14 This invention discloses an intelligent reinforcement device for FPC boards and provides the following three technical solutions: The first embodiment includes a chassis 1 and an attachment mechanism 2 installed inside it. The chassis 1 is used to install other electrical components of the equipment. An inspection door can be provided on the side of the chassis 1 to facilitate the inspection and maintenance of the internal equipment. The attachment mechanism 2 includes a bracket 3. The bracket 3 transmits FPC board strips 14 with FPC boards attached and reinforcement strips 41 with reinforcing plates attached on both sides. FPC board brackets 7 and reinforcement plate brackets 6 are fixedly connected to both sides of the bracket 3 to support the FPC board strips 14 and reinforcement strips 41.

[0024] The bracket 3 is also equipped with a transfer and attachment mechanism 8, which is used to pick up the reinforcing plate on the reinforcing plate strip 41 and transfer it to the FPC strip 14 for pressing and attaching. The transfer and attachment mechanism 8 includes: The portal frame 81 is fixed and erected on the bracket 3; U-shaped frame 82 is fixedly connected to the bottom of portal frame 81; The adsorption and transfer mechanism 83 is slidably disposed inside the U-shaped frame 82, and a first push rod 84 is fixedly connected to one end of the U-shaped frame 82 to push and pull the U-shaped frame 82; the adsorption and transfer mechanism 83 includes: The sliding frame 831 is slidably connected to the U-shaped frame 82 via sliding shafts 833 fixed on both sides; Multiple sliding negative pressure seats 832 are provided inside the slide frame 831 and are elastically suspended inside the slide frame 831 by rubber bands 834; The top of the portal frame 81 is also longitudinally slidably connected with a first pressure block 89 and a second pressure block 810. The first pressure block 89, the second pressure block 810 and the bottom surface of the portal frame 81 are all provided with positioning grooves 812 for positioning and guiding the movement trajectory of the sliding negative pressure seat 832. The first pressure block 89 and the second pressure block 810 drive the sliding negative pressure seat 832 to rise and fall through lifting. The sliding negative pressure seat 832 is hollow and has an air suction hole 8321 at the bottom. A self-tightening air suction device 85 is connected to one side of the sliding negative pressure seat 832. The self-tightening air suction device 85 evacuates the sliding negative pressure seat 832 to generate negative pressure in the air suction hole 8321 to suck up the reinforcing plate. A vertical shaft 8322 is fixedly connected to the top of the sliding negative pressure seat 8322, and an I-shaped sleeve 8323 is rotatably sleeved on the outside of the vertical shaft 8322. The I-shaped sleeve 8323 rolls in the positioning groove 812. An annular groove is opened in the middle of the side of the I-shaped sleeve 8323, and the inner walls of the positioning groove 812 are provided with protruding ridges that fit the annular groove.

[0025] The first pressure block 89 and the second pressure block 810 are located above the reinforcing strip 41 and the FPC strip 14, respectively. The top of the portal frame 81 is provided with a sliding groove 811 that is compatible with the first pressure block 89 and the second pressure block 810. Both sides of the U-shaped frame 82 are provided with support grooves 821 that are slidably connected to the sliding shaft 833. The top of the portal frame 81, above the slide groove 811, is fixedly connected to the second push rod 87 and the third push rod 88 via the mounting bracket 86. The output ends of the second push rod 87 and the third push rod 88 are fixedly connected to the top of the first pressure block 89 and the second pressure block 810, respectively.

[0026] This application involves simultaneously transferring FPC boards and reinforcing plates onto paper tapes. Multiple reinforcing plates on a single FPC board are attached to different paper tapes. The transfer and attachment mechanism 8 simultaneously picks up and moves these reinforcing plates onto the FPC board, and lowering it completes the simultaneous attachment of multiple reinforcing plates. The transfer and attachment mechanism 8 utilizes the cooperation of a sliding negative pressure seat 832 and a positioning groove 812 to position the sliding negative pressure seat 832 in two locations. Multiple sliding negative pressure seats 832 move independently, evenly distributing multiple rows of reinforcing plate tapes 41 at the loading position, while at the other end, their positions can be rearranged according to the reinforcement location. This ensures accurate and efficient reinforcement, significantly improving efficiency compared to using a robotic arm to clamp and attach each plate individually. Furthermore, the transfer and attachment mechanism 8 features a modular design; the gantry frame 81, first pressure block 89, second pressure block 810, and other structures can be replaced as needed, allowing for adjustments based on the reinforcement location of different FPC boards, thus providing versatility.

[0027] The second embodiment differs from the first embodiment mainly in that the self-tightening suction device 85 includes: The suction hose 851 is provided in multiple parts and is connected to one side of multiple sliding negative pressure seats 832 respectively. The other end of the multiple suction hoses 851 is connected to the main pipe 854. The upright frame 852 is fixedly connected to the top of the bracket 3, and the main pipe 854 is fixedly connected to the top of the upright frame 852; Multiple pulleys 853 are provided and rotatably connected to the top of the upright 852. The suction hose 851 slides through the slide frame 831 and the U-shaped frame 82 and overlaps the pulleys 853. The counterweight ring 855 is fitted onto the section of the suction hose 851 located between the U-shaped frame 82 and the pulley 853.

[0028] By setting a self-tightening suction device 85, air can be drawn from the sliding negative pressure seat 832 to create negative pressure at its bottom to absorb the reinforcing plate. Since the sliding negative pressure seat 832 needs to be moved, in order to prevent the suction hose 851 from drooping and folding inside the U-shaped frame 82 and affecting the operation, a counterweight ring 855 is fitted on the part of the suction hose 851 located outside the U-shaped frame 82. When the sliding negative pressure seat 832 moves, the suction hose 851 will extend and retract outside the U-shaped frame 82 without affecting the processing operation and is easy to use.

[0029] The third implementation differs from the first implementation in that: a reinforcing plate winding drum 9, multiple first guide roller groups 12, and a second guide roller group 13 are rotatably connected to both sides of the bracket 3. The reinforcing plate winding drum 9 is used to wind up the release paper of the reinforcing plate strip 41 after the reinforcing plate is removed, and the multiple first guide roller groups 12 and the second guide roller groups 13 are used to guide the tracks of the reinforcing plate strip 41 and the FPC strip 14, respectively. A winding drum drive motor 10 is fixedly connected to one side of the bracket 3. The winding drum drive motor 10 is a servo motor that can precisely control the number of rotations. To improve the winding speed of the reinforcing plate strip 41, an industrial camera or infrared displacement sensor can be added to monitor the displacement of the winding reinforcing plate strip 41. The output end of the winding drum drive motor 10 is connected to the reinforcing plate winding drum 9 through a pulley assembly 11, and the output end of the winding drum drive motor 10 is connected to the drive pulley of the pulley assembly 11 through a torque sensor. By connecting the winding drum drive motor 10 and the pulley assembly 11 that drives the reinforcing plate winding drum 9 to rotate with a torque sensor, the torque between the winding drum drive motor 10 and the reinforcing plate winding drum 9 can be monitored and controlled in real time. This allows the reinforcing plate winding drum 9 to maintain a certain tension on the reinforcing plate strip 41, preventing slack and facilitating the release of the reinforcing plate from the release paper.

[0030] One end of the bracket 3 is equipped with a roll unwinding drive mechanism 5, and a reinforcing plate roll unwinding drum 4 is mounted and driven on the roll unwinding drive mechanism 5. The reinforcing plate roll unwinding drum 4 is provided with multiple rows of grooves, and reinforcing plate strips 41 with different shapes of reinforcing plates are wound around them respectively; the roll unwinding drive mechanism 5 includes: A prism shaft 51 is rotatably mounted on a bracket 3, and a reinforcing plate unwinding drum 4 is sleeved on the prism section of the prism shaft 51. A baffle 52 is sleeved on one end of the prism shaft 51 and on the side of the reinforcing plate unwinding drum 4 away from the bracket 3. A clamp 53 that restricts the baffle 52 is engaged at the end of the prism shaft 51. A driven gear 57 is fixedly connected to the other end of the prism shaft 51. The low-speed motor 55 is fixedly connected to the other side of the bracket 3 via the motor frame 54, and the output shaft of the low-speed motor 55 is fixedly connected to the driving gear 56 that meshes with the driven gear 57. Infrared sensor switch 59 is fixedly connected to the other side of bracket 3 and located on the side of active gear 56. A light-blocking plate 58 is fixedly connected to the surface of active gear 56. During the rotation of light-blocking plate 58, it intermittently blocks the infrared rays of infrared sensor switch 59. Each time it blocks the infrared rays, infrared sensor switch 59 sends an electrical signal, which is counted once by a counter.

[0031] The drive mechanism of the reinforcing plate unwinding drum 4 uses a combination of a driving gear 56 and a driven gear 57 to drive a low-speed motor 55 and a prism shaft 51, achieving intermittent transmission of the reinforcing plate unwinding drum 4. This allows for intermittent output of the reinforcing plate strip 41, thus reserving time for attaching the reinforcing plate. Furthermore, a light-blocking plate 58 is installed on the driving gear 56 in conjunction with an infrared sensor switch 59 to detect the number of rotations of the reinforcing plate unwinding drum 4. This not only facilitates the control of the speed of the low-speed motor 55 but also the calculation of the remaining number of layers of the reinforcing plate strip 41, thereby promptly reminding workers to replace the reinforcing plate unwinding drum 4 (an audible and visual alarm can be installed on the top of the housing 1 for alarm purposes), making it quite intelligent.

[0032] The fourth embodiment differs from the first embodiment mainly in that the reinforcing plate bracket 6 includes: The first support plate 61 is used to hold and support the bottom of the reinforcing strip 41; The first diagonal brace 62 is fixedly connected to the bottom of the first support plate 61, and its side is fixedly connected to the bracket 3 by bolts; Positioning dividers 63 are fixedly connected to the top two ends of the first support plate 61, and multiple rows of positioning dividers 63 are provided to separate and position the reinforcing plate strip 41 between the positioning dividers 63. FPC board bracket 7 includes: The second support plate 71 is used to hold and support the bottom of the FPC strip 14; The second diagonal brace 72 is fixedly connected to the bottom of the second support plate 71, and the second diagonal brace 72 and the first diagonal brace 62 are fixed together on the bracket 3 by the same bolts. Sliding dividers 73 are disposed at the top four corners of the second tray 71 to restrict the FPC strip 14 between the sliding dividers 73.

[0033] FPC board bracket 7 also includes: A double-acting lead screw 74 is rotatably connected to the bottom of the second support plate 71 via a bearing seat, and a handwheel 75 is fixedly connected to one end of the double-acting lead screw 74; Two threaded sleeves 76 are provided, each threadedly connected to the two reverse threads of the bidirectional lead screw 74; The insertion rod 77 is fixedly connected to both sides of the threaded sleeve 76, and the insertion rod 77 extends upward through the second support plate 71 and is inserted into the sliding partition block 73. The interior of the second support plate 71 is provided with a guide groove 78 that is compatible with the insertion rod 77.

[0034] The edges of the positioning separator 63 and the sliding separator 73 that contact the belt body are rounded to avoid scratching the belt body.

[0035] By setting a positioning divider 63 on the reinforcing plate bracket 6, multiple reinforcing plate strips 41 can be separated and their positions can be positioned. The reinforcing plate unwinding drum 4 can be replaced according to the specifications of the reinforcing plate strips 41. The sliding divider 73 with manually adjustable spacing is set on the FPC plate bracket 7 to accommodate FPC plate strips 14 of different widths, thus improving adaptability.

[0036] To improve the automation level of equipment operation, a control unit can be set up, connecting signals from devices such as torque sensors, infrared sensor switches 59, and counters to the control unit. The control unit then intelligently controls actuators such as the winding drum drive motor 10 and the low-speed motor 55. A display screen can also be set up to show the equipment's operating parameters and status information in real time. Furthermore, any content not described in detail in this specification is considered prior art known to those skilled in the art.

[0037] This invention also discloses a reinforcement method for an intelligent reinforcement device used in FPC boards, comprising the following steps: Step 1: Place the reinforcing plate onto the prism shaft 51 on the roll 4, then place the baffle 52 onto the prism shaft 51 and lock it with the clamp 53. Then pull out the reinforcing plate strip 41, pass it around the first guide roller group 12 and stick it to the surface of the reinforcing plate take-up drum 9. Then pass the FPC plate strip 14 around the second guide roller group 13 and pass it through the equipment, so that the FPC plate strip 14 and the reinforcing plate strip 41 rest on the FPC plate bracket 7 and the reinforcing plate bracket 6. Step 2: Start the transfer and attachment mechanism 8. First, control the second push rod 87 to push the first pressure block 89 down to press the sliding negative pressure seat 832, so that it presses against the reinforcing plate on the reinforcing plate strip 41. Then, start the air pump 856 to draw air out of the sliding negative pressure seat 832 through the air suction hose 851, so that the air suction hole 8321 generates negative pressure to suck up the reinforcing plate on the reinforcing plate strip 41 below. Then, raise the first pressure block 89, lift the sliding negative pressure seat 832 and the reinforcing plate, so that the reinforcing plate is separated from the release paper. Step 3: Move the sliding frame 831 and its inner sliding negative pressure seat 832 above the FPC strip 14 by pulling the first push rod 84.
