Description

Technical Field

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

[0002] With the rapid development of technology, flexible printed circuit board (FPC) production technology has become a research hotspot. Although existing technologies have made some progress in FPC production, the efficiency and accuracy of release liner separation remain major bottlenecks restricting production efficiency and product quality. For example, traditional blades are prone to uneven cutting and rapid blade wear when separating release liner, which not only affects production efficiency but also increases maintenance costs. Furthermore, sheet rewinding machines often encounter technical difficulties such as inaccurate tension control and uneven winding during the winding process, limiting further automation and efficiency improvements in FPC production. Therefore, this paper proposes developing a new blade module and a sheet rewinding machine to address these issues. Utility Model Content

[0003] This application provides a cutting tool module for a sheet material slitting and winding machine, including a blade and connecting rods. The blade extends outwards from both ends of its cutting edge to form a connecting shaft. Two connecting rods are located at both ends of the blade. Each connecting rod has a connecting port corresponding to the connecting shaft. A crack extends along the central plane formed by the central axis of the connecting port and the center of the connecting rod, extending from the connecting port towards the center of the connecting rod and turning. The end of the crack terminates on a plate surface parallel to the central plane. The crack extends from the plane of the connecting rod towards the blade and penetrates another opposing plane.

[0004] In some embodiments, the crack divides the connecting rod into a compression portion and a fixing portion, and the compression portion is squeezed toward the fixing portion to reduce the diameter of the connection opening, thereby fixing the connecting rod to the connecting shaft.

[0005] In some embodiments, the pressing part is fixed to the fixing part by a screw, and tightening the screw causes the pressing part to press against the fixing part.

[0006] In some embodiments, the connecting rod has a screw hole corresponding to the screw, the screw hole passing through the pressing part and extending into the fixing part.

[0007] In some embodiments, the connecting rod has a countersunk hole into which the screw extends, and the countersunk hole communicates with the screw hole.

[0008] In some embodiments, the cutting edge of the blade is formed by tilting from one plane to an opposite plane at an angle greater than or equal to 20 degrees and less than or equal to 35 degrees.

[0009] In some embodiments, an extension is formed extending outward along the blade surface, the extension being located at an end opposite to the blade cutting edge, and the connecting shaft is located on the extension.

[0010] In some embodiments, the extension is perpendicular to the blade's surface.

[0011] In some embodiments, the connecting rod has a slotted hole for connecting a device, the slotted hole being located at one end away from the connection port, the slotted hole extending from a plane facing the tool through an opposite plane.

[0012] This application also provides a sheet material slitting and rewinding integrated machine, including a frame, a slitting module, an auxiliary shaft, and a cutting tool module as described in any one of the above. The slitting module is mounted on the frame for slitting or rewinding sheet material, and includes a base and an air shaft. The auxiliary shaft is mounted on the support to change the path of the sheet material so that the sheet material reaches the rewinding slitting module. The cutting tool module is mounted on the frame, and the blades are tangent to the outer circular surface of the auxiliary shaft so that the blades separate the sheet material passing through the auxiliary shaft.

[0013] The cutting tool module and sheet slitting and winding machine of this application effectively solve the problems of uneven cutting, rapid wear, and inaccurate sheet winding tension control caused by traditional blades through innovative blade design and connecting rod structure. This design achieves high-precision cutting and stable winding, significantly improving the efficiency of release paper separation and the flatness of sheet winding, greatly reducing blade replacement frequency and equipment maintenance costs, and providing users with higher production efficiency and economic benefits. Therefore, this invention has broad application prospects and significant socio-economic value in the field of flexible printed circuit board (FPC) production.

[0027] Please see Figure 1 and Figure 2 This application provides a cutting tool module 50 for a sheet material slitting and winding machine 100. The cutting tool module 50 includes a blade 51 and connecting rods 52. The blade 51 extends outward from both ends of the blade to form a connecting shaft 511. Two connecting rods 52 are located at the two ends of the blade 51. The connecting rods 52 have connecting ports 521 corresponding to the connecting shaft 511. A crack 522 extends along the central plane formed by the central axis of the connecting port 521 and the center of the connecting rod 52. The crack extends from the connecting port 521 toward the center of the connecting rod 52 and turns. The end of the crack 522 terminates on a plate surface parallel to the central plane. The crack 522 penetrates the opposite plane from the plane of the connecting rod 52 toward the blade.

[0028] The cutting tool module 50 and the sheet material slitting and winding integrated machine 100 of this application effectively solve the problems of uneven cutting, rapid wear, and inaccurate sheet material winding tension control caused by traditional blades through the innovative blade design 52 and connecting rod 52 structure. This design achieves high-precision cutting and stable winding, significantly improving the efficiency of release paper separation and the flatness of sheet material winding, greatly reducing the frequency of blade replacement and equipment maintenance costs, and providing users with higher production efficiency and economic benefits. Therefore, this invention has broad application prospects and significant socio-economic value in the field of flexible printed circuit board (FPC) production.

[0029] Please see Figure 1 and Figure 2 The sheet material slitting 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 a rewinding module 60. 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 4The 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 The slitting module 60 is mounted on the frame 10. The slitting module 60 is used for winding or unwinding sheet material. The slitting module 60 includes a base 61 and an air shaft 62 mounted on the base 61. In the embodiments of this application, two slitting modules 60 are provided above the pressing module 40, and one slitting 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 upper right-side slitting module 60, and passes through the driven shaft 46 to the driving roller 42 and driven roller 44. After being compressed, the sheet and film reach the auxiliary shaft 13, and finally, the lower slitting module 60 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 slitting module 60, and then released onto the auxiliary shaft 13 with the cutter module 50. After separation, the product changes its path after passing through other auxiliary shafts 13, and then reaches the lower slitting module 60 for winding.
