Referring to fig. 1 and 2, a five-in-one forming apparatus 10 according to an embodiment of the present invention includes a frame feeding device 100, a CCM feeding device 200, a laminating device 300, and a folding device 400.

The five-in-one molding apparatus 10 is used to prepare the third composite tape 40 shown in fig. 7 and 8. The third composite material tape 40 includes an upper frame material tape 41, a lower frame material tape 42, a plurality of CCM (catalyst/proton exchange membrane) sheets 43 and two outermost protective film material tapes 44, wherein the CCM sheets 43 are sandwiched between the upper frame material tape 41 and the lower frame material tape 42 and are arranged at intervals along the extending direction of the third composite material tape 40.

The CCM sheet 43 includes a proton membrane and catalyst layers formed on both sides of the proton membrane, and the proton membrane and the catalyst layers on both sides of the upper frame strip 41, the lower frame strip 42, and the CCM sheet 43 form a five-in-one assembly. When the five-in-one module is used, the two outermost layers of the protective film material strips 44 need to be torn off. A plurality of hollow-out grooves 1011 are formed in the areas corresponding to the upper frame material strip 41 and the lower frame material strip 42 at intervals along the extending direction of the third composite material strip 40. The catalyst layer of each CCM sheet 43 is disposed corresponding to the hollow grooves 1011 on the upper frame material tape 41 and the lower frame material tape 42 to form a functional area. The reaction gas can chemically react at the functional region to generate electric power when the fuel cell is operated.

The frame feeding device 100 is used for providing a first composite tape 20, and the first composite tape 20 includes a back film tape 21 and a frame tape 22. The side of the backing film strip 21 facing the frame strip 22 is typically coated with an adhesive for bonding with the frame strip 22. In addition, the back film tape 21 and the frame tape 22 may be combined by electrostatic adsorption. The width of the strip of framing material 22 is greater than the width of a conventional frame, and is approximately twice the width of the upper or

lower framing strip

41, 42.

As shown in fig. 9 and 10, the frame material tape 22 is formed with dual hollow portions 101 sequentially arranged along the length direction, and each dual hollow portion 101 includes two hollow grooves 1011 spaced along the width direction of the frame material tape 22. That is to say, two rows of the hollow-out grooves 1011 are formed on the frame material belt 22, each row includes a plurality of hollow-out grooves 1011 arranged at intervals in the length direction of the frame material belt 22, and the two rows of the hollow-out grooves 1011 are arranged at intervals in the width direction of the frame material belt 22. The two hollow-out slots 1011 of the same double hollow-out portion 101 are aligned in the width direction of the frame material tape 22, and are generally distributed in an axisymmetric manner with the center line of the first composite material tape 20 as a symmetry axis (a dashed line in the figure).

Specifically, in the present embodiment, the frame feeding device 100 includes a frame unwinding member 110 and a frame making mechanism 120. The frame unwinding member 110 is used for unwinding an initial composite tape (not shown), which includes a back film tape 21 and an initial frame tape (not shown); the frame-making mechanism 120 is used for processing the initial composite material belt to form the dual hollow-out portion 101 on the initial frame material belt.

The initial frame material strip is the frame material strip 22 before processing, and the double hollow-out portions 101 do not exist on the initial frame material strip, so the double hollow-out portions 101 are not formed on the initial composite material strip unreeled by the frame unreeling member 110. After being processed by the frame-making mechanism 120, the initial frame tape is hollowed out to form a double hollowed-out portion 101, so that the initial frame tape becomes the frame tape 22, and the initial composite tape becomes the first composite tape 20. That is, the frame feeding device 100 provides the first composite material tape 20 required by the subsequent work in an online framing manner, so that the real-time adjustment of the framing process according to the alignment error in the actual processing process is facilitated.

It should be noted that, in other embodiments, the first composite tape 20 provided by the frame feeding device 100 can be prepared off-line, i.e., the frame is first formed and stored by a special device, and then directly unreeled when in use.

Referring to fig. 3, in the embodiment, the frame-making mechanism 120 includes a first bottom roller 121, a first cutter roller 124 and a waste discharge assembly 125.

The waste discharge assembly 125 includes a waste discharge roller 1251, and the waste discharge roller 1251 and the first cutter roller 124 are disposed at an interval in the circumferential direction of the first base roller 121. The first bottom roller 121 has a larger diameter than the first cutter roller 124 and the waste discharge assembly 125, and the initial composite tape unwound by the frame unwinding member 110 can be wound around the first bottom roller 121. The first cutter roll 124 is capable of roll-cutting the initial composite strip passing around the first bottom roll 121 to form the double hollow 101 on the initial frame strip. The surface of the first cutter roll 124 is provided with a blade, and the initial composite material strip can be continuously rolled and cut by matching with the first bottom roll 121 to form the double hollow-out part 101.

The waste discharge assembly 125 is used for removing waste materials generated by processing the double hollow-out portion 101, so as to expose the double hollow-out portion 101, thereby obtaining the finally formed first composite material tape 20. Wherein, the waste discharge roller 1251 is located at the downstream of the first cutter roller 124, the waste discharge adhesive tape can be wound around the waste discharge roller 1251, and the waste material formed by cutting the first cutter roller 124 is removed from the double hollow part 101.

Specifically, the waste tape passing through the waste roller 1251 can be pressed against the initial composite tape passing through the first bottom roller 121, and the sticky side of the waste tape is outward, i.e., toward the first bottom roller 121. Therefore, the waste tape can stick the waste material at the waste roller 1251, and take away the waste material from the dual hollow-out portion 101 along with the waste tape being wound. In addition, the waste discharging assembly 125 further includes a tape unwinding member 1252 and a tape winding member 1253. The waste tape is unwound by the tape unwinding member 1252, and is wound by the tape winding member 1253 after being reversed by the waste discharge roller 1251.

Further, in the present embodiment, the frame-making mechanism 120 further includes a guide roller 122 and a guide-out roller 123, the guide roller 122 and the guide-out roller 123 are disposed at intervals along the circumferential direction of the first base roller 121, the initial composite tape can be guided into the first base roller 121 by the guide roller 122, and the processed first composite tape 20 can be guided out by the guide-out roller 123. The guide roller 122 and the guide roller 123 are matched to form a larger enveloping angle between the initial composite tape and the first composite tape 20 on the first bottom roller 121, so that the initial composite tape and the first composite tape 20 are tightly attached to the first bottom roller 121, and the stability of the initial composite tape and the first composite tape 20 in the subsequent processing process is facilitated.

In addition, in the present embodiment, the frame-making mechanism 120 can further cover a mask sheet (not shown) on the area of the back film material tape 21 corresponding to the dual hollow-out portion 101. After obtaining two fretwork portions 101, cover and establish the mask sheet stock and can cover the regional that back film material area 21 and two fretwork portions 101 correspond. In this way, in the five-in-one module, the protective film tapes 44 on both sides, i.e., the back film tape 21, will not directly contact the CCM sheet material 43 of the functional region, thereby preventing the occurrence of blocking. Therefore, when the protective film material strips 44 on the two sides of the five-in-one component are torn off in the subsequent use process, the catalyst layer on the surface of the CCM sheet material 43 cannot be damaged, and therefore the function damage of the five-in-one component is avoided.

Of course, in the case of compounding the back film tape 21 and the initial frame tape by electrostatic adsorption, the frame-making mechanism 120 does not need to cover a mask sheet in the region corresponding to the double hollow-out portion 101.

Referring to fig. 3 again, in the embodiment, the frame-making mechanism 120 further includes a film-coating assembly 126, and the film-coating assembly 126 includes a film-coating roller 1261, a second cutter roller 1263 and a mask winding member 1264.

The laminating roller 1261 and the second cutter roller 1263 are provided at intervals in the circumferential direction of the first base roller 121, the laminating roller 1261 is located on the side of the waste discharge roller 1251 away from the first cutter roller 124, and the second cutter roller 1263 is located on the side of the laminating roller 1261 away from the waste discharge roller 1251. The frame mask can be wrapped around the laminating roller 1261 and combined with the first strip of composite material 20 at the first backing roller 121. The film covering roller 1261 can be matched with the first bottom roller 121, so that the frame mask and the first composite material strip 20 can be combined under the rolling action of the film covering roller 1261 and the first bottom roller 121. In addition, the film covering assembly 126 generally further includes a mask unwinding member 1262, and the mask unwinding member 1262 is capable of unwinding the frame mask.

The second cutter roller 1263 has substantially the same structure as the first cutter roller 124. The second cutter roller 1263 can roll cut the frame mask in cooperation with the first bottom roller 121 to cut the region of the frame mask corresponding to the double hollow-out portion 101 into mask sheet materials. Next, the mask winding member 1264 winds the frame mask which is roll-cut by the second cutter roller 1263. The frame mask is torn off from the surface of the first composite material tape 20 by the pulling of the mask rolling member 1264, and the cut mask sheet is left in the double hollow part 101 due to the adhesion of the back film material tape 21, thereby completing the covering of the mask sheet.

The first cutter roller 124, the waste discharge roller 1251, the laminating roller 1261, and the second cutter roller 1263 are positioned between the introduction roller 122 and the discharge roller 123. The first bottom roller 121 has a large diameter, and the introduction roller 122, the discharge roller 123, the first cutter roller 124, the waste discharge roller 1251, the laminating roller 1261, and the second cutter roller 1263 have a small diameter and are distributed in a satellite manner around the circumferential direction of the first bottom roller 121. Therefore, the structure of the framing mechanism 120 is more compact.

CCM supply apparatus 200 is used to sequentially supply a plurality of CCM sheets 43. The CCM sheet 43 provided by the CCM feeding device 200 and the first composite tape 20 can enter the attaching device 300, and the attaching device 300 can sequentially attach the CCM sheet 43 to any hollow-out slot 1011 of each of the double hollow-out portions 101 to obtain the second composite tape 30. When the attaching device 300 attaches, only one CCM sheet 43 is attached to each of the double hollow portions 101, and the attached CCM sheet 43 may be located at any hollow groove 1011 of the double hollow portions 101.

As shown in fig. 9, in the present embodiment, the applying device 300 can apply the CCM sheet 43 to the hollow-out grooves 1011 of the two hollow-out portions 101 on the same side in sequence. That is to say, CCM sheet 43 in a plurality of double hollow portions 101 is either attached to the hollow-out groove 1011 on the upper side or attached to the hollow-out groove 1011 on the lower side. In this way, the position of the laminating apparatus 300 when laminating a plurality of CCM sheet materials 43 can be kept unchanged, thereby facilitating alignment without repeatedly adjusting the laminating position in the laminating process.

It should be noted that, in other embodiments, the applying device 300 can apply the CCM sheet 43 to the hollow-out grooves 1011 on different sides of the double hollow-out portions 101. For example, in another embodiment shown in fig. 10, CCM sheets 43 in two adjacent double hollow portions 101 are respectively attached to the hollow grooves 1011 on different sides.

The CCM sheet 43 supplied from the CCM supply device 200 may be prepared off-line, i.e., produced and stored by a dedicated apparatus, and directly supplied to the laminating device 300 at a predetermined frequency at the time of lamination. In addition, CCM sheet 43 can also be prepared in real time.

Referring to fig. 4, in the present embodiment, the CCM feeding device 200 includes a CCM unwinding member 210, a second bottom roller 220, a third cutter roller 230, and a transition roller 240.

The CCM unwinding member 210 can unwind the CCM tape 50 at a first linear speed. The second bottom roller 220 is capable of adsorbing the CCM tape 50 and operates at a second linear velocity that is greater than the first linear velocity. As a result, there is slippage between the CCM web 50 and the second bottom roll 220.

The third cutter roller 230 can cooperate with the second bottom roller 220 to sever the CCM material strip 50 and obtain the CCM sheet 43 adsorbed to the second bottom roller 220. A plurality of blades are arranged at equal intervals in the circumferential direction of the third cutter roller 230, and synchronously meshed with the second bottom roller 220, so that the CCM material belt 50 can be continuously cut into a plurality of CCM sheet materials 43 with equal length. Since the second bottom roller 220 can adsorb the CCM sheet 43, the second linear velocity is higher than the first linear velocity, i.e., the running velocity of the CCM material tape 50. Thus, at the instant each CCM sheet 43 is severed from the strip of CCM material 50, it will accelerate to the second linear velocity, thereby pulling a distance from the remaining strip of CCM material 50. It can be seen that, a required interval can be formed between a plurality of CCM sheets 43 obtained by roll cutting by matching the third cutter roll 230 and the second bottom roll 220, and the interval can be matched with the interval between the double hollow-out portions 101 on the frame material belt 22 by specifically setting the first linear speed and the second linear speed, so that the prepared CCM sheets 43 can be directly compounded with the first composite material belt 20.

Both second bottom roll 220 and transition roll 240 may be vacuum rolls. The transition roller 240 abuts the second bottom roller 220 and can be operated at the second linear speed, and the CCM sheet 43 adsorbed on the second bottom roller 220 can be transferred to the transition roller 240 with the second bottom roller 220. Therefore, the space on the surface of the second bottom roller 220 can be timely emptied, so that the next CCM sheet material 43 can be conveniently and quickly prepared, and the production efficiency is ensured.

Specifically, in this embodiment, the CCM feeding device 200 further includes a pulling roll 250 positioned between the CCM unwinding member 210 and the second bottom roll 220, and the pulling roll 250 is capable of absorbing and pulling the CCM material tape 50 at the first linear speed. The pull roll 250 may also be a vacuum roll, so as to be able to adsorb the CCM tape 50, and the pull roll 250 may be connected to a separate driving component, such as a servo motor, so as to control the tape running speed of the CCM tape 50.

In addition, a tension detection roller (not shown) is generally arranged between the CCM unwinding member 210 and the traction roller 250, and the tension detection roller can feed back the tension of the CCM material belt 50 and can tension or relax the CCM material belt 50 according to the tension, so that stable belt feeding is realized.

It should be noted that, in other embodiments, the feeding speed of the CCM material tape 50 may also be controlled by the unwinding speed of the CCM unwinding member 210.

Further, in the present embodiment, the applying device 300 includes a third bottom roller 310 and an applying roller 320, the first composite tape 20 can be wound around the third bottom roller 310, and the applying roller 320 is located between the third bottom roller 310 and the transition roller 240. Further, the third bottom roller 310 and the laminating roller 320 can both be operated at the second linear speed, and the CCM sheet 43 adsorbed on the transition roller 240 can be transferred to the laminating roller 320 along with the transition roller 240 and laminated to the first composite tape 20 at the third bottom roller 310.

The third bottom roll 310 may be a rubber roll, and the laminating roll 320 is also a vacuum roll in general, and its surface is subjected to an anti-sticking treatment to prevent adhesion with the CCM sheet 43. Since both the third bottom roller 310 and the laminating roller 320 can operate at the second linear speed, the CCM sheet 43 can be kept in synchronization with the first composite tape 20 at the third bottom roller 310, and can be laminated under the pressing of the laminating roller 320 and the third bottom roller 310. It can be seen that the first composite tape 20 can remain running during the application process without stopping, so that continuous production can be achieved.

One side of the CCM tape 50 is covered with a protective film tape (not shown). Thus, the CCM sheet material 43 thus produced is coated with a protective film sheet material (not shown) on the side facing away from the first composite tape 20. In order to expose the surface of the CCM sheet material 43, it is necessary to remove the protective film sheet material on the surface of the CCM sheet material 43 before the second composite tape 30 enters the doubling device 400.

Referring to fig. 1 again, in the present embodiment, a film tearing device 500 is further disposed between the laminating device 300 and the folding device 400, and the film tearing device 500 is used for removing the protective film sheet from the surface of the CCM sheet 43.

The film tearing apparatus 500 comprises an unwinding roll 510, a winding roll 520, an intermediate roll 530 and a support roll 540, and the second composite tape 30 can be wound around the support roll 540 and fed towards the folding apparatus 400. The waste discharge adhesive tape is unreeled by the unreeling shaft 510, and is reeled by the reeling shaft 520 after being reversed by the intermediate roller 530, and the waste discharge adhesive tape wound by the intermediate roller 530 can be contacted with the CCM sheet material 43 on the supporting roller 540. Specifically, the side of the waste tape having viscosity around the intermediate roller 530 is directed outward, i.e., toward the support roller 540. Therefore, the waste tape can stick to the protective film sheet on the surface of the CCM sheet 43 at the support roller 540 and take the protective film sheet away from the surface of the CCM sheet 43 as the waste tape is wound up.

It should be noted that in other embodiments, tear away device 500 may also perform removal of the protective film web in other ways. For example, a robot with a suction cup is used to grasp the protective film sheet on the surface of the CCM sheet 43.

The folding device 400 can fold the second composite tape 30 in half along the center line of the second composite tape 30, and overlap the two hollow-out slots 1011 of the double hollow-out portion 101 to form the third composite tape 40. After being attached by the attaching device 300, one CCM sheet 43 is attached to each of the double hollow portions 101. Therefore, when the folding device 400 folds the second composite material strap 30, the CCM sheet 43 is clamped between the two hollow-out slots 1011 to form a functional area of the five-in-one assembly. It can be seen that the back film tape 21 of the first composite tape 20 will constitute the outermost protective film tape 44 of the third composite tape 40, and the frame tape 22 can be used as the upper frame tape 41 or the lower frame tape 42 of the five-in-one module. Therefore, the second composite material strip 30 is folded in half to obtain the third composite material strip 40, and simultaneously the five-in-one assembly is obtained, thus completing the five-in-one molding.

Referring to fig. 5 and fig. 6, in the present embodiment, the folding device 400 includes a feeding roller 410, a discharging mechanism 420, and a partition 430.

The second composite tape 30 can be wound around an input roll 410. The discharging mechanism 420 is spaced from the feeding roller 410. The discharging mechanism 420 includes a first nip roller 421 and a second nip roller 422 disposed oppositely, the rotation axes of the first nip roller 421 and the second nip roller 422 are parallel to each other, and the rotation axis of the feeding roller 410 is perpendicular to the rotation axes of the first nip roller 421 and the second nip roller 422. The second composite material belt 30 passing through the feeding roller 410 can enter the discharging mechanism 420 and pass between the first nip roller 421 and the second nip roller 422

The partition 430 is disposed between the feeding roller 410 and the discharging mechanism 420, and the second composite tape 30 wound around the feeding roller 410 can pass through between the first nip roller 421 and the second nip roller 422 after being guided by the partition 430. The second composite tape 30 can be folded in half by the partition 430, and is squeezed by the first nip roller 421 and the second nip roller 422 to obtain a third composite tape 40.

The first nip roller 421 and the second nip roller 422 can be driven by a servo motor to rotate, and an air cylinder can be arranged outside the first nip roller 421 and the second nip roller 422 to clamp the first nip roller 421 and the second nip roller 422. The second composite tape 30 travels from the infeed roller 410 to the outfeed mechanism 420 past the baffle 430, with the edge of the baffle 430 generally aligned with the centerline of the second composite tape 30. Therefore, under the supporting action of the partition 430, the second composite tape 30 will gradually fold inward (i.e. the side attached with the CCM sheet 43) during the traveling process, and two portions on two sides of the center line of the second composite tape 30 are tightly attached after being rolled by the first nip roller 421 and the second nip roller 422, so as to obtain the third composite tape 40.

The folio device 400 is also generally provided with a deviation rectifier 440, the deviation rectifier 440 being located before the feed roll 410. The deviation rectifier 440 can rectify the second composite tape 30 in the width direction, so that the center line of the second composite tape 30 is aligned with the partition 430 at a high degree.

Referring to fig. 1 again, in the present embodiment, the frame feeding device 100 further includes a slitting mechanism 130, the slitting mechanism 130 is disposed between the frame unwinding member 110 and the frame making mechanism 120, and the slitting mechanism 130 slits the backing film material tape 21 along a center line of the initial composite material tape. The slit strip of backing film 21 is evenly divided into two portions, with the gap between the two portions being able to act as a crease line for the first strip of composite material 20. Therefore, when the folding device 400 folds the second composite material tape 30, the precision of the folding can be improved.

Referring to fig. 2 again, in the embodiment, the five-in-one molding apparatus 10 further includes a hot press device 600, and the third composite material tape 40 output by the folding device 400 can enter the hot press device 600 and be pressed by the hot press device 600. The hot press device 600 can further enhance the bonding force between the two layers of frame material tapes 22, thereby improving the reliability of the third composite material tape 40.

Specifically, the surface of the frame material tape 22 is coated with a thermal sensitive adhesive in advance. The hot press apparatus 600 includes a first hot press roller, a heating roller, and a cooling roller. The first hot-press roller is heated and pressed to discharge bubbles in the third composite material belt 40, is further heated by the heating roller to increase the bonding force, and is shaped by the cooling roller. In the thermal compression compounding process, the first thermal compression roller, the heating roller and the cooling roller are operated synchronously to keep the tension of the third compound material belt 40 constant.

It should be noted that, in other embodiments, the surface of the frame tape 22 may also be coated with a pressure sensitive adhesive, and in this case, the hot pressing is not required, and the hot pressing device 600 may be omitted.

In this embodiment, the five-in-one molding apparatus 10 further includes a finished product winding device 700, and the finished product winding device 700 is capable of winding the third composite material tape 40. The third composite material tape 40 wound by the finished product winding device 700 can be stored in a material roll form and can be directly unwound when the five-in-one component is required to be used.

It should be noted that in other embodiments, the third composite tape 40 may not be wound, but may be directly circulated to the next process.

In the five-in-one molding apparatus 10, the attaching device 300 can sequentially attach the CCM sheet 43 provided by the CCM feeding device 200 to the first composite material strip 20 provided by the frame feeding device 100 to obtain the second composite material strip 30, and the CCM sheet 43 is attached to any hollow-out slot 1011 of each of the double hollow-out portions 101. After the folding device 400 folds the second composite material tape 30 along the central line, the two hollow-out slots 1011 of the double hollow-out portion 101 are overlapped, so that the CCM sheet 43 is clamped between the two hollow-out slots 1011 to form a functional area of the five-in-one component. As can be seen, the frame material belt 22 can be used as both the upper frame and the lower frame of the five-in-one assembly, so that the number of material rolls can be significantly reduced when the five-in-one assembly is manufactured by using the above five-in-one molding apparatus 10. Therefore, the structure of the five-in-one molding apparatus 10 is simpler.

In addition, the invention also provides a five-in-one molding method.

Referring to fig. 11, the five-in-one molding method in one embodiment of the invention includes steps S810 to S830:

step S810, providing a first composite tape 20, where the first composite tape 20 includes a back film tape 21 and a frame tape 22, and the frame tape 22 is formed with dual hollow portions 101 sequentially arranged along a length direction, and each dual hollow portion 101 includes two hollow grooves 1011 spaced along a width direction of the frame tape 22.

The width of the border strip 22 is greater than the width of a conventional border, approximately twice the width of the upper border strip 41 or the lower border strip 42. The two hollow-out slots 1011 of the same double hollow-out portion 101 are aligned in the width direction of the frame material tape 22, and are generally distributed in an axisymmetric manner with the central line of the first composite material tape 20 as the symmetry axis.

Specifically, in this embodiment, the step S810 includes: unreeling an initial composite material belt, wherein the initial composite material belt comprises a back film material belt 21 and an initial frame material belt; processing the initial composite material belt to form a double hollow-out part 101 on the initial frame material belt and obtain a first composite material belt 20; compounding the frame mask with the first composite material belt 20, and performing roller cutting on the frame mask to cut the region of the frame mask corresponding to the double hollow-out part 101 into mask sheet materials; and coiling the frame mask after the roll cutting, and keeping the mask sheet in the area corresponding to the double hollow-out part 101.

The initial frame material strip is the frame material strip 22 before processing, and the double hollow-out portions 101 do not exist on the initial frame material strip, so that the double hollow-out portions 101 do not exist on the unwound initial composite material strip. After framing, the initial frame strip is hollowed out to form a double hollowed-out portion 101, so that the initial frame strip becomes the frame strip 22, and the initial composite strip becomes the first composite strip 20. That is, the first composite material tape 20 is fed in an on-line framing manner, so that the framing process can be adjusted in real time conveniently according to the alignment error in the actual processing process.

Furthermore, after the above steps, a mask sheet (not shown) can be coated on the area of the back film material strip 21 corresponding to the double hollow-out portion 101. In the five-in-one assembly, the protective film tapes 44 on both sides, i.e. the back film tape 21, will not directly contact the CCM sheet 43 of the functional region, thereby preventing adhesion. Therefore, when the protective film material strips 44 on the two sides of the five-in-one component are torn off in the subsequent use process, the catalyst layer on the surface of the CCM sheet material 43 cannot be damaged, and the function damage of the five-in-one component is avoided.

In step S820, the CCM sheet 43 is sequentially attached to any hollow-out slot 1011 of each of the double hollow-out portions 101 to obtain the second composite material tape 30.

Specifically, when the two hollow portions 101 are bonded, only one CCM sheet 43 is bonded in each of the two hollow portions 101, and the bonded CCM sheet 43 may be located at any hollow groove 1011 of the two hollow portions 101.

As shown in fig. 9, in the present embodiment, the CCM sheet 43 is sequentially attached to the hollow-out grooves 1011 of the same side of each of the double hollow-out portions 101. Thus, the positions of the plurality of CCM sheet materials 43 can be kept unchanged, so that the alignment is convenient, and the attachment position does not need to be adjusted repeatedly in the attachment process.

It should be noted that, in other embodiments, the CCM sheet 43 can be attached to the hollow-out grooves 1011 on different sides of the double hollow-out portions 101. In another embodiment, as shown in fig. 10, the CCM sheets 43 in two adjacent double hollow portions 101 are respectively attached to the hollow grooves 1011 on different sides.

CCM web 43 required for lamination can be prepared off-line, i.e., produced and stored by specialized equipment, and fed directly at a predetermined frequency during lamination. In addition, CCM sheet 43 can also be prepared in real time. Specifically in this embodiment, the CCM sheet 43 is made in real time using a CCM tape.

Step S830, the second composite tape 30 is folded in half along the central line of the second composite tape 30, and the two hollow-out slots 1011 of the double hollow-out portion 101 are overlapped, so as to complete the five-in-one molding and obtain the third composite tape 40.

After the lamination, a CCM sheet 43 is laminated in each double hollow-out portion 101. Therefore, when the second composite tape 30 is folded in half, the CCM sheet 43 is clamped between the two hollow-out slots 1011 to form the functional area of the five-in-one module. It can be seen that the back film tape 21 of the first composite tape 20 will constitute the outermost protective film tape 44 of the third composite tape 40, and the frame tape 22 can be used as the upper frame tape 41 or the lower frame tape 42 of the five-in-one module. Therefore, the second composite material strip 30 is folded in half to obtain the third composite material strip 40, and simultaneously the five-in-one assembly is obtained, thus completing the five-in-one molding.

In this embodiment, before the step of processing the initial composite tape to form the dual hollow-outs 101 on the initial frame tape, the method further includes slitting the backing film tape 21 along a center line of the initial composite tape. The slit strip of backing film 21 is evenly divided into two portions, with the gap between the two portions being able to act as a crease line for the first strip of composite material 20. Therefore, when the second composite tape 30 is folded in half, the accuracy of the folding in half can be improved.

In this embodiment, after the step of obtaining the third composite tape 40, a step of rolling the third composite tape 40 is further included. The third composite material belt 40 after rolling can be stored in a material roll form and can be directly unreeled when a five-in-one assembly is needed.

In the five-in-one forming method, the CCM sheet 43 is sequentially adhered to the first composite material tape 20 to obtain the second composite material tape 30, and the CCM sheet 43 is adhered to any hollow-out slot 1011 of each of the double hollow-out portions 101. After the second composite material tape 30 is folded in half along the central line, the two hollow-out grooves 1011 of the double hollow-out portion 101 are overlapped, so that the CCM sheet material 43 is clamped between the two hollow-out grooves 1011 to form a functional area of the five-in-one component. It can be seen that the frame material belt 22 can be used as both the upper frame and the lower frame of the five-in-one assembly, so that when the five-in-one assembly is prepared by the above five-in-one forming method, the number of material rolls can be significantly reduced, thereby the operation process is simpler and the structure of the forming equipment can be simplified.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
