Description

Technical Field

[0001] This application relates to the field of FPC manufacturing technology, and more specifically, to a sheet material rewinding machine. Background Technology

[0002] In the production of flexible printed circuit boards (FPCs), lamination and sheet rewinding are core processes. Traditional processes require separate lamination and rewinding operations, resulting in large footprints for both. This approach leads to fragmented processes, low efficiency, and sheet displacement or creases during transfer, causing a decrease in yield. Existing rewinding equipment often uses a single cutting tool, lacking integrated control with the lamination process. This results in residual lamination material or incomplete cutting during rewinding, requiring manual secondary processing. Furthermore, conventional transport systems lack sufficient adhesion stability for ultra-thin sheets, leading to air bubbles or wrinkles during lamination and lamination. There is an urgent need to develop equipment that integrates lamination and lamination with precise rewinding, improving production efficiency through process integration to meet the FPC industry's demands for high-precision, automated production.

[0027] Please see Figure 1 and Figure 2This application discloses a sheet material slitting and rewinding integrated machine 100, comprising: a frame 10, a feeding module 20, a conveying module 30, a pressing module 40, a cutting tool module 50, and an unwinding module 60. The frame 10 is provided with multiple auxiliary shafts 13. The feeding module 20 is used for feeding sheet materials. The conveying module 30 includes a belt conveyor assembly 31 and a suction assembly 32. The belt conveyor assembly 31 is used to convey the sheet materials, and the suction assembly 32 is used to adsorb the sheet materials onto the belt conveyor assembly 331. The pressing module 40 is used to press the sheet materials and the coating material together. The pressing module 40 includes a drive roller 42, a driven roller 44, and a driven shaft 46. The driven roller 44 is above the drive roller 42, and the driven shaft 46 is used to change the conveying path of the coating material so that the coating material can reach between the drive roller 42 and the driven roller 44. The cutting tool module 50 is used to separate the coating material. The cutting tool module includes blades 51, which are tangential to one of the auxiliary shafts. The unwinding module 60 is used for unwinding or winding the sheet material; during lamination, the pressing module 40 operates and the cutting tool module 50 stops; during separation, the pressing module 40 stops and the cutting tool module 60 operates.

[0028] This application's sheet material slitting and rewinding integrated machine 100 significantly improves FPC production efficiency and product yield by integrating lamination and slitting processes. The equipment utilizes a suction assembly 32 in conjunction with a belt conveyor to ensure stable transport of ultra-thin sheets, preventing displacement or wrinkles. Through alternating linkage control of the lamination module 40 and the cutting tool module 50, precise switching between lamination and material separation is achieved, completing lamination and slitting in one step, eliminating the need for manual secondary processing in traditional processes. The modular structure design, combined with auxiliary shaft guidance, optimizes the lamination path and tension control, reducing air bubble formation. During slitting, the cutting tool and auxiliary shaft work tangentially to ensure complete separation of the lamination material without residue, while the unwinding module 60 enables rapid rewinding, reducing manual intervention. The overall equipment combines high integration and automation advantages, meeting the high-precision processing requirements of ultra-thin FPC materials and significantly reducing production costs.

[0029] Please see Figure 1 and Figure 2 The sheet material unwinding and rewinding integrated machine 100 includes a frame 10, a feeding module 20, a transmission module 30, a pressing module 40, a cutting tool module 50, and an unwinding module 60. The feeding module 20, transmission module 30, pressing module 40, cutting tool module 50, and unwinding module 60 are detachably connected to the frame 10. Detachment methods include screw connections and clamping fixation. The frame 10 is equipped with a PLC control box 11 and a mounting box 12, and is divided along its thickness to form two chambers: the front chamber houses the PLC control box 11, and the rear chamber houses the mounting box 12. The frame 10 is equipped with multiple auxiliary shafts 13, which are used to change the sheet material transmission path. The positions of the auxiliary shafts can be set as needed and will not be described further.

[0030] Please combine Figure 3 and Figure 4 The feeding module 20 is mounted on the frame 10. The feeding module 20 includes a feeding platform 21 and baffles 22. The feeding platform 21 is used to place and transport sheet materials, and the baffles 22 are mounted on the feeding platform 21. Two parallel baffles 22 are installed on both sides of the sheet material transport path to prevent the sheet materials from deviating from the predetermined track. An adjusting plate 221, L-shaped, is provided on the side of the baffle 22 facing away from the sheet material. One surface of the adjusting plate 221 is fixed to the surface of the baffle 22, and the other surface of the adjusting plate 221 is in contact with the upper surface of the feeding platform 21, perpendicular to the baffle 22.

[0031] The adjusting plate 221 has an adjusting groove 222 in a direction perpendicular to the surface of the baffle 22, and the adjusting groove 222 passes through the upper and lower surfaces of the adjusting plate 221. The loading platform 21 has a fixing rod 211 at a position corresponding to the adjusting groove 222. The fixing rod 211 passes through the adjusting groove 222 and has threads. Tightening a fixing nut on the fixing rod 211 fixes the adjusting plate 221 in a designated position. In the embodiment of this application, each baffle 22 has two adjusting plates 221, and each adjusting plate 221 has two adjusting grooves 222. The number of fixing rods 211 corresponds to the number of adjusting grooves 222.

[0032] Please see Figure 2 , Figure 4 and Figure 5 The conveying module 30 is used to transport sheet materials along the sheet material transport path. The conveying module 30 includes a belt conveyor assembly 312 and a suction assembly 32. The belt conveyor assembly 312 includes a rotating shaft 311, a belt 312, and a drive motor 314. Two rotating shafts 311 are arranged in parallel and spaced apart and mounted on the frame 10. The belt 312 is wrapped around the outer circumference of the two rotating shafts 311 and has multiple ventilation holes 313 penetrating the upper and lower surfaces. The drive motor 314 is mounted on the frame 10 and is connected to one of the rotating shafts 311. The rotation of the drive motor 314 drives the rotating shaft 311 to rotate, thereby driving the belt 312 to rotate.

[0033] The suction assembly 32 includes a suction box 321 and a negative pressure fan 322. The suction box 321 is installed between the upper and lower belts. A vent 323 is provided on the upper surface of the suction box 321, and the upper surface of the suction box 321 is in contact with the lower surface of the upper belt 312. The vent 323 communicates with a vent 313. The suction box 321 also has a suction port 324, which is connected to the negative pressure fan 322. When the fan is turned on, a negative pressure is created inside the suction box 321. As the sheet material passes over the belt 312, the sheet material is drawn in through the vent 323 and vent 313, ensuring it adheres tightly to the upper surface of the belt 312. This prevents the sheet material from shifting or warping, thus avoiding any impact on product yield. It should be noted that the air intake 324 and the air vent 323 can be arranged in a regular array or irregularly. The number of both can be the same or different, and there is no special limitation, as long as they can tightly suck up the sheet material. The negative pressure fan 322 is installed in the mounting box 12, and one side of the mounting box 12 has an air vent mesh 121 that corresponds to the air outlet of the negative pressure fan 322.

[0034] Furthermore, in order to enable the air intake 324 to generate suction perpendicular to the surface of the belt 312, the air intake 324 is located at the bottom of the air intake box 321. Specifically, the width of the air intake box 321 is greater than the width of the belt 312, and the air intake 324 is opened below the empty area of ​​the air intake box 321 where the width of the belt 312 is greater. The air intake 324 draws air downward, so that the air intake 324 generates suction perpendicular to the surface of the upper plate of the box.

[0035] Furthermore, the belt 312 is located in the middle of the suction box 321, and the suction box 321 has empty areas on both sides of the belt 312. Two suction ports 324 are provided, located in the empty areas on both sides of the suction box 321, and the suction ports 324 are arranged diagonally opposite each other. In the embodiment of this application, in order to facilitate the sheet material to adhere tightly to the upper surface of the belt 312, the diameter of the vent 313 is less than or equal to the diameter of the vent 323. Along the width direction of the belt 312, the width of the area formed by the multiple vents 323 is greater than or equal to the width of the area formed by the multiple vents 323, which is greater than the width of the sheet material.

[0036] Multiple pressure rollers 315 are arranged above the belt 312. The frame 10 has notches corresponding to the rotating shafts 311 at both ends of the pressure rollers 315. The pressure rollers 315 are used to prevent the sheet material from wrinkling or warping during transportation. Furthermore, to prevent the sheet material from warping at the edges, tangential pressure rollers 315 are arranged at positions perpendicular to the rotating shafts 311. The frame 10 is also equipped with a sensor (not shown) for checking whether the sheet material has reached the designated position on the belt 31. The sensor can be a photoelectric sensor, laser sensor, etc.

[0037] Please see Figure 2 , Figure 4 and Figure 6 The pressing module 40 is used to press the sheet material and release paper together. The pressing module 40 includes a mounting block 41 and a drive roller 42, a power motor 43, a driven roller 44, and an adjusting cylinder 45 mounted on the mounting block 41. The drive roller 42 and the driven roller 44 are mounted on the same vertical plane, and have the same diameter, with the driven roller 44 positioned above the drive roller 42. The power motor 43 is connected to the drive roller 42, driving it to rotate. The driven roller 44 is connected to the adjusting cylinder 45, causing it to move up and down.

[0038] Specifically, the mounting block 41 is provided with a vertical guide groove 411, and the output shaft of the adjusting cylinder 45 extends into the guide groove 411. A movable block 451 adapted to the guide groove 411 is provided on the output shaft of the adjusting cylinder 45. The upper end of the movable block 451 is connected to the output shaft, and the bottom end of the movable block 451 has a shaft hole 452 for the driven roller 44 to be rotatably mounted. The output shaft of the adjusting cylinder 45 drives the driven roller 44 to move downwards, causing the driven roller 44 to press against the driving roller 42, thereby achieving the pressing of both the sheet material and the release paper as they pass through. Furthermore, the pressing module 40 also includes a driven shaft 46, which is disposed between the two mounting blocks 41 and is used to change the direction of sheet material transmission.

[0039] Please see Figure 2 , Figure 4 and Figure 7 The cutting tool module 50 is used to separate the sheet material and the release paper. The cutting tool module 50 includes a blade 51 and connecting rods 52. The blade 51 is rectangular and is fixed to the frame 10 via the connecting rods 52. The cutting edge of the blade 51 extends from one plate surface to the opposite plate surface, and the blade 51 has an inclination of [20°, 35°]. The sides of the blade 51 at both ends extend outward to form connecting shafts 511. Two connecting rods 52 are respectively positioned on the sides of the blade 51 at both ends. One end of each connecting rod 52 has a connecting port 521 corresponding to the connecting shaft 511, into which the connecting shaft 511 extends to complete the rotatable connection between the two.

[0040] In one embodiment, to prevent the blade connecting rod 52 from affecting product separation during operation, a protrusion 512 is formed on the end of 51 that protrudes perpendicularly to the plate surface, away from the cutting edge, and the connecting shaft 511 is located on the protrusion 512. In the embodiments of this application, the blade 51 is tangent to the outer circular surface of the auxiliary shaft 13 and parallel to the sheet material transport path.

[0041] Furthermore, to facilitate adjustment of the blade 51's cutting edge angle relative to the horizontal plane, a slit 522 extends outward from the connection opening 521, penetrating the outer surface of the connecting rod 52. Specifically, the slit 522 extends from the connection opening 521 towards the center of the connecting rod 52, penetrating from the side adjacent to the blade 51 to the opposite side. Simultaneously, the end of the slit 522 bends and extends through a surface perpendicular to the side. The slit 522 divides the connecting rod 52 in its middle plane, forming a fixing part 524 and a pressing part 523. The pressing part 523 presses against the fixing part 524, reducing the diameter of the connection opening 521, thereby fixing the connecting rod 52 to the blade 51. When it is necessary to adjust the angle of the blade 51, the pressing part 523 can be released.

[0042] Furthermore, to facilitate the fixing of the connecting shaft 511, a screw hole 525 is provided on the fixing part 524. The screw hole 525 passes through the pressing part 523 and extends to the fixing part 524. By tightening the screw 526, the pressing part 523 can be pressed against the fixing part 524, thus completing the fixing of the connecting shaft 511 and the connecting rod 52. In the embodiment of this application, to prevent the screw 526 from protruding and easily scratching the product, a countersunk hole for nut accommodation is provided on the fixing part 524. The screw 526 is tightened with a hex wrench.

[0043] The connecting rod 52 is fixed to the frame 10 by a threaded rod 53. The connecting rod 52 has a slotted hole 527 extending through two opposing surfaces on its side facing the frame 10. The length of the slotted hole 527 is the same as the length of the connecting rod 52. The threaded rod 53 passes through the slotted hole 527 and is fixed to the frame 10. By adjusting the relative position of the threaded rod 53 in the slotted hole 527, the distance between the cutting tool 51 and the frame 10 can be adjusted, as can the angle of the entire tool module 50 relative to the horizontal plane. In this embodiment, the threaded rod 53 is fixed to the frame 10, and the slotted hole 527 is fitted onto the rotating shaft of the auxiliary shaft 13.

[0044] Please see Figure 1 and Figure 2 An unwinding module 60 is mounted on the frame 10. The unwinding module 60 is used for winding or unwinding the sheet material. The unwinding module 60 includes a base 61 and an air shaft 62 mounted on the base 61. In the embodiments of this application, two unwinding modules 60 are provided above the pressing module 40, and one unwinding module 60 is provided below the pressing module 40.

[0045] During lamination, the material is fed by the feeding module 20, passes through the transfer module 30, and reaches the driving roller 42 and driven roller 44 of the pressing module 40. The film is released by the unwinding module 60 on the upper right side, and passes through the driven shaft 46 to the driving roller 42 and driven roller 44. After being compressed, the sheet and the film reach the auxiliary shaft 13, and finally, the unwinding module 60 at the bottom winds them up to complete the lamination. At this time, the cutter module 50 is removed, or the auxiliary shaft 13, which is tangent to the cutter module 50, is avoided to prevent affecting the winding of the product.

[0046] During separation, the coated product is placed on the upper unwinding module 60, and then released onto the auxiliary shaft 13 with the cutter module 50. After separation, it changes its path after passing through other auxiliary shafts 13 and reaches the lower unwinding module 60 for winding.
