[0002] ACF materials (Anisotropic Conductive Film) are widely used in electronic products. When using them, they often need to be cut and rolled up.

[0003] After the ACF material is cut, it needs to be stripped. Since the ACF material includes two layers, when the width after cutting is too small, such as 0.4 mm, the ACF material is prone to reverse peeling (delamination), and thus cannot be used.

[0004] In the prior art, there are generally two-stage roller devices, and the angle between the two roller devices is relatively large, which causes the ACF material to be subjected to a relatively large force during the transmission process, further causing the ACF material to peel back. Summary of the invention

[0014] The present invention also provides an ACF material cutting and winding system, comprising a cutter, a plurality of winding devices, and the above-mentioned ACF material stripping device, wherein the cutter is arranged in front of the first roller, and the cutter cuts the ACF material into a plurality of ACF units, and the plurality of ACF units pass through a first guide groove, a second guide groove, a third guide groove, and a fourth guide groove in sequence, and are respectively wound at a plurality of winding devices.

[0049] Example 1

[0050] like Figure 1 As shown, this embodiment discloses an ACF material stripping device, including a roller assembly. The roller assembly includes a first roller 100, a second roller 110, a third roller 120 and a fourth roller 130; the first roller 100, the second roller 110, the third roller 120 and the fourth roller 130 are sequentially arranged along the direction of movement of the ACF material (arranged in parallel and spaced apart), and the cutter cuts the ACF material into a plurality of ACF units 200 with smaller widths. In this embodiment, the width of the ACF unit 200 does not exceed 0.4 mm.

[0051] like Figure 2 , 3 As shown, specifically, a plurality of first guide grooves 140 are spaced apart on the outer surface of the first roller 100, and the distance between two adjacent first guide grooves 140 ranges from 0.8 to 1.2 mm; Figure 5 , 6 As shown, a plurality of second guide grooves 150 are spaced apart on the outer surface of the second roller 110, and the distance between two adjacent second guide grooves 150 ranges from 4.5 to 5.5 mm; Figure 8 , 9As shown, a plurality of third guide grooves 160 are spaced apart on the outer surface of the third roller 120, and the distance between two adjacent third guide grooves 160 ranges from 14.5 to 15.5 mm; Fig.11 , 12 As shown, a plurality of fourth guide grooves 170 are spaced apart on the outer surface of the fourth roller 130, and the distance between two adjacent fourth guide grooves 170 ranges from 27 to 28 mm. A plurality of ACF units 200 enter the first guide groove 140, the second guide groove 150, the third guide groove 160, and the fourth guide groove 170 in sequence, and the distance between adjacent ACF units 200 increases with the forward movement, thereby achieving the purpose of separating the ACF units 200, and then the separated ACF units 200 are rolled up onto the rolling device 300.

[0052] Preferably, the spacing between two adjacent first guide grooves 140 is the same, which is 1 mm; the spacing between two adjacent second guide grooves 150 is the same, which is 5 mm; the spacing between two adjacent third guide grooves 160 is the same, which is 15 mm; the spacing between two adjacent fourth guide grooves 170 is the same, which is 27.5 mm. Such spacing arrangement can most effectively separate multiple ACF units 200.

[0053] In this embodiment, the number of the ACF units 200 , the first guide grooves 140 , the second guide grooves 150 , the third guide grooves 160 , and the fourth guide grooves 170 are all the same.

[0054] like Figure 3 , 6 As shown in FIGS. 9 and 12, specifically, in this embodiment, the number of the first guide groove 140, the second guide groove 150, the third guide groove 160, and the fourth guide groove 170 is fifteen, and accordingly, the number of the ACF units 200 after being cut by the tool is also fifteen. The fifteen ACF units 200 enter the corresponding guide grooves in the first guide groove 140, the second guide groove 150, the third guide groove 160, and the fourth guide groove 170 respectively.

[0055] like Figure 4 As shown, in this embodiment, the cross section of the first guide groove 140 includes a rectangular opening close to the central axis of the first roller 100 and a tapered opening close to the outer surface of the first roller 100. The tapered opening is connected to the rectangular opening, and the angle between the extended line of the tapered opening and the rectangular opening is 15°. The width of the rectangular opening (the width of the first guide groove 140) is 0.45 mm, the allowable tolerance range is 0-0.05 mm, and the outer end width of the tapered opening is 0.8 mm.

[0056] like Figure 7As shown, the cross section of the second guide groove 150 includes a rectangular opening close to the central axis of the second roller 110 and a tapered opening close to the outer surface of the second roller 110. The tapered opening is connected to the rectangular opening, and the angle between the extended line of the tapered opening and the rectangular opening is 20°. The width of the rectangular opening (the width of the second guide groove 150) is 0.45 mm, the allowable tolerance range is 0-0.03 mm, and the outer end width of the tapered opening is 1.45 mm.

[0057] like Fig.10 As shown, the cross section of the third guide groove 160 includes a rectangular opening close to the central axis of the third roller 120 and a tapered opening close to the outer surface of the third roller 120. The tapered opening is connected to the rectangular opening, and the angle between the extended line of the tapered opening and the rectangular opening is 20°. The width of the rectangular opening (the width of the third guide groove 150) is 0.45 mm, the allowable tolerance range is 0-0.03 mm, and the outer end width of the tapered opening is 1.45 mm.

[0058] like Fig.13 As shown, the cross section of the fourth guide groove 170 includes a rectangular opening close to the central axis of the fourth roller 130 and a tapered opening close to the outer surface of the fourth roller 130, the tapered opening is connected to the rectangular opening, and the angle between the extended line of the tapered opening and the rectangular opening is 20°. The width of the rectangular opening (the width of the third guide groove 150) is 0.45 mm, the allowable tolerance range is 0-0.03 mm, and the outer end width of the tapered opening is 1.45 mm.

[0059] It can be seen that the angles of the tapered openings of the second guide groove 150, the third guide groove 160, and the fourth guide groove 170 are all greater than that of the first guide groove 140. And due to the tolerance range, the width of the first guide groove 140 is greater than that of the second guide groove 150, the third guide groove 160, and the fourth guide groove 170, so that the ACF unit 200 can more easily enter the second guide groove 150, the third guide groove 160, and the fourth guide groove 170 when moving.

[0060] like Figure 1 As shown, optionally, the heights of the first roller 100, the second roller 110, the third roller 120, and the fourth roller 130 are different. Specifically, the heights of the first roller 100, the second roller 110, the third roller 120, and the fourth roller 130 decrease in sequence. Such a structural design is conducive to the transportation of the ACF unit 200, and is also conducive to ensuring the smoothness of the ACF unit 200 during transportation, thereby avoiding reverse peeling. The height of the winding device 300 is lower than the height of the fourth roller 130, which is conducive to the winding device 300 to wind up the ACF unit 200.

[0061] The ACF material stripping device in this embodiment arranges the first roller 100, the second roller 110, the third roller 120, and the fourth roller 130 in parallel to ensure that the ACF unit 200 is basically transported in a straight line during transportation, thereby avoiding the ACF unit 200 from turning at a large angle, and further avoiding the reverse peeling of the ACF unit 200. In addition, the guide groove intervals of the four-stage rollers are expanded successively, and the ACF unit 200 passing through the four-stage rollers is gradually separated, thereby facilitating the subsequent winding operation, and the multi-stage expansion of the spacing is conducive to reducing the large-angle turning of the ACF unit 200, further avoiding the reverse peeling phenomenon.

[0062] Example 2

[0063] The present embodiment discloses an ACF material cutting and winding system, including a cutter, a plurality of winding devices 300, and the ACF material stripping device in Embodiment 1. The cutter is arranged in front of the first roller 100, and the cutter cuts the ACF material into a plurality of ACF units 200. The plurality of ACF units 200 sequentially pass through the first guide groove 140, the second guide groove 150, the third guide groove 160, and the fourth guide groove 170, and are respectively wound at the plurality of winding devices 300.

[0064] In this embodiment, a tool is arranged in front of the first roller 100 to separate the ACF material into fifteen ACF units 200 with a width of 0.4 mm. The fifteen ACF units 200 respectively enter the fifteen first guide grooves 140 on the first roller 100, and then respectively pass through the second guide groove 150 of the second roller 110, the third guide groove 160 of the third roller 120, and the fourth guide groove 170 of the fourth roller 130, and then complete the winding at the winding device 300.

[0065] Specifically, the number of the winding devices 300 is fifteen, and the fifteen winding devices 300 are sequentially arranged behind each fourth guide groove 170 of the fourth roller 130, and the ACF unit 200 coming out of the fourth guide groove 170 is wound on each winding device 300 respectively.

[0066] The ACF material cutting and winding system in this embodiment adopts the ACF material slitting device in Example 1, which can effectively avoid the reverse peeling of the ACF material during the cutting, transportation and winding process.

[0067] Example 3

[0068] This embodiment discloses a 0.4 mm ACF unit 200 striping and rolling method, using the ACF material striping device in embodiment 1, the method is as follows:

[0069] The plurality of 0.4 mm ACF units 200 cut by the knife are overlapped in the first guide grooves 140 of the first roller 100 respectively;

[0070] The plurality of 0.4 mm ACF units 200 passing through the first guide groove 140 are overlapped in the corresponding second guide grooves 150 on the second roller 110 respectively;

[0071] The plurality of 0.4 mm ACF units 200 passing through the second guide groove 150 are overlapped in the corresponding third guide grooves 160 on the third roller 120 respectively;

[0072] The plurality of 0.4 mm ACF units 200 passing through the third guide groove 160 are overlapped in the corresponding fourth guide grooves 170 on the fourth roller 130 respectively;

[0073] Finally, the ACF unit 200 passing through the fourth guide groove 170 is wound on the winding device 300 .

[0074] Specifically, the cutter cuts the ACF material into fifteen ACF units 200 with a width of 0.4 mm, the first ACF unit 200 is located in the first first guide groove 140 of the first roller 100, the second ACF unit 200 is located in the second first guide groove 140 of the first roller 100, and so on, the fifteenth ACF unit 200 is located in the fifteenth first guide groove 140 of the first roller 100. Similarly, multiple ACF units 200 pass through the corresponding second guide groove 150, third guide groove 160, and fourth guide groove 170 in sequence, and finally, are rolled up on the winding device 300 behind the fourth roller 130.

[0075] The 0.4 mm ACF unit 200 strip winding method in this embodiment sets the first roller 100, the second roller 110, the third roller 120, and the fourth roller 130 in parallel to ensure that the ACF unit 200 is basically transported in a straight line during transportation, thereby avoiding large-angle turning of the ACF unit 200, and further avoiding the reverse peeling of the ACF unit 200. In addition, the guide groove spacing of the four-stage rollers is expanded successively, and the ACF unit 200 passing through the four-stage rollers is gradually separated, which is convenient for subsequent winding operations, and the multi-stage expansion of the spacing is conducive to reducing the large-angle turning of the ACF unit 200, further avoiding the reverse peeling phenomenon. This method is suitable for ACF products with smaller widths.

[0076] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
