[0025] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1

[0027] Refer to Figure 1 In a slitter in an embodiment of the present invention, it includes a first conveying assembly 1 for conveying the main film 100, a second conveying assembly 2 for conveying the protective film 200, a film laminating assembly 3 for laminating the main film 100 and the protective film 200 in a predetermined path section, and a slitting assembly 4 for slitting the laminated main film 100 and protective film 200 in a predetermined path section.

[0028] Refer to Figure 2, the first conveying assembly 1 includes a first unwinding member 11 and a plurality of first winding members 12. The first conveying assembly 1 enables the conveying path of the main film 100 to extend from the first unwinding member 11 to the first winding members 12. Refer to Figure 3 , the second conveying assembly 2 includes a second unwinding member 21 and a second winding member 22. The second conveying assembly 2 enables the conveying path of the protective film 200 to extend from the second unwinding member 21 to the second winding member 22.

[0029] Refer to Figure 1 , a plurality of first guide rollers 5 are further provided on the conveying path of the main film 100 of the first conveying assembly 1. The positions of the plurality of first guide rollers 5 are arranged such that the front and back sides of the main film 100 are alternately wound therearound, so that the conveying path of the main film 100 is bent (in combination with Figure 2 ).

[0030] Continue to refer to Figure 1 , a plurality of second guide rollers 6 are further provided on the conveying path of the protective film 200 of the second conveying assembly 2. The positions of the plurality of second guide rollers 6 are arranged such that the front and back sides of the protective film 200 are alternately wound therearound, so that the conveying path of the protective film 200 is bent (in combination with Figure 3 ).

[0031] The first guide rollers 5 and the second guide rollers 6 can further restrict the shapes and conveying directions of the conveying paths of the main film 100 and the protective film 200, and the bent arrangements of the conveying paths of the main film 100 and the protective film 200 can ensure the tension of the film material conveying.

[0032] Refer to Figure 1 , the laminating assembly 3 includes a laminating roller 31 provided at the starting point of a predetermined path segment. The laminating roller 31 is arranged such that both the main film 100 conveyed by the first conveying assembly 1 and the protective film 200 conveyed by the second conveying assembly 2 are wound therearound and then laminated.

[0033] Refer to Figure 1 , the slitting assembly 4 includes a plurality of cutting knives. The end point of the predetermined path segment is the output end of the slitting assembly 4. The main film 100 after being laminated with the protective film 200 is slit into a plurality of sheets of film materials that meet the design width requirements at the slitting assembly 4. Therefore, in this embodiment, the predetermined path segment is the overlapping part of the conveying path of the main film 100 and the conveying path of the protective film 200.

[0034] During operation, the main film 100 runs from the first unwinding member 11 to the first winding member 12, and the protective film 200 runs from the second unwinding member 21 to the second winding member 22. At the laminating roller 31, the main film 100 is laminated with the protective film 200. Then, the laminated main film 100 and protective film 200 are conveyed to the slitting assembly 4, where the main film 100 and the protective film 200 are simultaneously slit by a cutter. Since the protective film 200 is provided on the surface of the main film 100, the dust particles generated by cutting the film material adhere to the protective film 200, so that the main film 100 is not adhered with dust particles.

[0035] Referring to Figure 1 , in the conveying direction of a predetermined path segment, the laminating assembly 3 further includes two pressing rollers 32 provided downstream of the laminating roller 31; and / or in the conveying direction of a predetermined path segment, the laminating assembly 3 further includes a tensioning roller 33 provided downstream of the laminating roller 31.

[0036] In this embodiment, both the pressing roller 32 and the tensioning roller 33 are provided on the predetermined path segment. The pressing roller 32 can further ensure the laminating effect between the main film 100 and the protective film 200, and the tensioning roller 33 can ensure the tension degree of the main film 100 and the protective film 200, so as to ensure the conveyance of the main film 100 and the protective film 200. In other embodiments, either the pressing roller 32 or the tensioning roller 33 can be selectively provided.

[0037] Referring to Figure 1 , taking the slitting of the main film 100 and the protective film 200 into two film materials by the slitting assembly 4 as an example, the conveying path of the main film 100 of the first conveying assembly 1 and the conveying path of the protective film 200 of the second conveying assembly 2 have different conveying orientations after passing through the output end of the slitting assembly 4. At this time, the main film 100 and the protective film 200 with different conveying orientations are convenient to be separated after cutting and enter the corresponding first winding member 12 and second winding member 22.

[0038] Continuing to refer to Figure 1 , after passing through the output end of the slitting assembly 4, the conveying path of the main film 100 of the first conveying assembly 1 includes at least two main film branch conveying paths, and adjacent main film branch conveying paths have different conveying orientations. In this embodiment, the first winding member 12 corresponds to the main film branch conveying paths, and the number of the first winding members 12 is one more than the number of cutters.

[0039] Since the whole-width main film 100 forms multiple film materials that meet the design width requirements after being cut by the slitting assembly 4. Therefore, multiple main film branch conveying paths can independently complete the organized winding of the slit main film 100. At the same time, since adjacent main film branch conveying paths have different conveying orientations, adjacent main films 100 can be better separated, which is also beneficial to the layout of the corresponding winding members downstream.

[0040] In this embodiment, a plurality of dust-removing rollers 7 are further arranged on the conveying path of the main film 100 of the first conveying assembly 1, and the dust-removing rollers 7 are abutted and installed on both sides of the main film 100. The dust-removing rollers 7 can effectively remove the dust that may remain on the main film 100.

[0041] Embodiment 2

[0042] It should be noted that in this embodiment, the main film 100 is taken as a copper film, and the protective film 200 is taken as a CPP film (Cast Polypropylene, cast polypropylene film) as an example. The above does not mean that the main film 100 in the present invention is limited to the copper film, and the protective film 200 is limited to the CPP film.

[0043] Refer to Figure 1 , the difference between this embodiment and Embodiment 1 is that in this embodiment, the second conveying assembly 2 is used to convey a plurality of separated protective films 200, the film laminating assembly 3 is used to laminate the plurality of protective films 200 to the main film 100 in a predetermined path section, and the slitting assembly 4 includes a plurality of cutters corresponding to the positions of the plurality of protective films 200.

[0044] After the protective film 200 with the same width as the main film 100 is laminated on the main film 100, during slitting, the protective film 200 can effectively prevent the dust particles generated by cutting from adhering to the main film 100. After slitting, the protective film 200 is separated from the main film 100. Since the bonding area between the whole-width protective film 200 and the main film 100 is large, the separation may cause the main film 100 to be damaged or even destroyed due to excessive tearing force, resulting in the final product not meeting the requirements. Especially for the copper film, when actually separating the CPP film from the copper film, since the copper film is relatively soft in texture, some positions of the copper film may be easily torn to produce light-transmitting points, which does not meet the actual requirements.

[0045] In this embodiment, a plurality of protective films 200 are provided. Before the slitting assembly 4 cuts, the plurality of protective films 200 are independently laminated on the to-be-slitted positions of the protective film 200 respectively. Therefore, when cutting the main film 100 and the protective film 200, the protective film 200 can still prevent the dust particles generated at the cutter from adhering to the main film 100. Since the bonding area between the protective film 200 and the main film 100 is reduced, when separating the protective film 200 from the main film 100, the tearing force between the two is small, so as to minimize the possibility of damage to the main film 100 as much as possible to ensure that the main film 100 after cutting meets the requirements.

[0046] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.

[0047] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
