Referring to fig. 1, a five-in-one molding apparatus 10 according to an embodiment of the present invention includes a first feeding device 100, a second feeding device 200, a third feeding device 300, and a bonding device 400.

The five-in-one forming apparatus 10 is used for preparing a five-in-one material belt 20 as shown in fig. 5, the five-in-one material belt 20 includes an upper frame material belt 21, a lower frame material belt 22, and a plurality of CCM (catalyst/proton exchange membrane) chips 23, the CCM chips 23 are sandwiched between the upper frame material belt 21 and the lower frame material belt 22, and are arranged at intervals along the extending direction of the five-in-one material belt 20. The CCM sheet 23 includes a proton membrane and catalyst layers formed on both sides of the proton membrane, and the term "pentahapto" refers to the composition of the upper frame material tape 21, the lower frame material tape 22, the proton membrane, and the catalyst layers on both sides.

The outermost layers on both sides of the five-in-one material tape 20 are generally attached with protective films 24 to protect the upper frame material tape 21, the lower frame material tape 22 and the CCM sheets 23. The five-in-one material belt 20 has a plurality of spaced functional regions in the extending direction, and the catalyst layer of each CCM sheet 23 is disposed at the hollow positions corresponding to the upper frame material belt 21 and the lower frame material belt 22 to form the functional regions. The reaction gas can chemically react at the functional region to generate electric power when the fuel cell is operated.

The first discharging device 100 is used for conveying a first composite material tape, where the first composite material tape includes a first transfer film material tape and an upper frame material tape 21 attached to the first transfer film material tape. The first transfer film material belt has better toughness and can be used as a support carrier for conveying the upper frame material belt 21. The first discharging device 100 can realize continuous discharging of the first composite material strip. The first composite material belt can be processed in advance and stored, and the first discharging device 100 can directly convey the processed first composite material belt to the attaching device 400, so that the structure of the first discharging device 100 is simplified. In addition, the first discharging device 100 can also perform compounding of the first transfer film material belt and the upper frame material belt 21 while conveying the first composite material belt, thereby realizing real-time preparation of the first composite material belt. Thus, the overall accuracy error of the five-in-one molding apparatus 10 can be conveniently controlled.

In this embodiment, the first discharging device 100 includes a first unwinding mechanism 110, a first combining mechanism 120, and a cutting mechanism 130. Wherein:

the first unwinding mechanism 110 includes a transfer film unwinding part 111 and a frame unwinding part 112, which are respectively used for unwinding the first transfer film tape and the frame feeding tape 21. Specifically, the transfer film unwinding part 111 and the frame unwinding part 112 may be unwinding rollers, and are respectively used for storing and unwinding the first transfer film material tape and the upper frame material tape 21. The first combining mechanism 120 is located at the downstream of the first unwinding mechanism 110, and the first transfer film tape and the upper frame tape 21 unwound by the first unwinding mechanism 110 enter the first combining mechanism 120 after being subjected to deviation correction in the width direction. The first composite mechanism 120 can press the first transfer film tape and the upper frame tape 21, so as to obtain a first composite tape.

The surface of the upper frame material belt 21 facing away from the first transfer film material belt is generally pre-coated with a curing adhesive, which may be a heat-sensitive adhesive or a pressure-sensitive adhesive. In addition, the surface of the first transfer film material belt facing the upper frame material belt 21 may also be formed with bonding areas by gluing, and the bonding areas are located at the edges of the first transfer film material belt in the width direction. Thus, when the first composite tape is bonded to the CCM chips 23, the first transfer film tape does not adhere to the catalyst layer of the CCM chips 23 located in the functional region.

Specifically, in the embodiment, the first combining mechanism 120 includes a first driving roller 121, two first passing rollers 122 and a first supporting roller 123, the two first passing rollers 122 and the first driving roller 121 are disposed at intervals, the first transfer film material tape and the upper frame material tape 21 can respectively pass through the first passing rollers 122 and are wrapped around the first driving roller 121, and the first supporting roller 123 presses the first transfer film material tape and the upper frame material tape 21 on the first driving roller 121.

The first driving roller 121 is a driving roller, and the two first passing rollers 122 and the first abutting roller 123 are driven rollers. Before entering the first driving roller 121, the first transfer film tape and the upper frame tape 21 may be respectively changed in angle by two first passing rollers 122 to enter the first driving roller 121, thereby generating a wrap angle. Moreover, the presence of stiff resistance increases the tension in the film, and the two first rollers 122 are located at a short distance from the first driving roller 121, which is not enough to generate the wave in the contraction or extension direction of the first transfer film belt and the upper frame belt 21. In this way, the first transfer film tape and the upper frame tape 21 can be equivalently wrapped on the first driving roller 121, so as to obtain better composite quality. In addition, the first abutting roller 123 can isolate the composite tension and roll the first transfer film material strip and the upper frame material strip 21, so that the first transfer film material strip and the upper frame material strip are better attached to each other.

Obviously, in other embodiments, the first transfer film material strip and the upper frame material strip 21 may also be directly roll-bonded by using two pairs of rollers.

Further, the cutting mechanism 130 is located downstream of the first composite mechanism 120, and is configured to cut the first composite tape to form functional areas on the upper frame tape 21 at intervals along the length direction. The first composite material tape compounded by the first compounding mechanism 120 can be continuously conveyed to the cutting mechanism 130, and the cutting mechanism 130 only cuts the upper frame material tape 21 without cutting the first transfer film material tape, so that hollow areas, namely functional areas, which are arranged at intervals along the length direction are formed on the upper frame material tape 21.

In this embodiment, the cutting mechanism 130 includes a first vacuum knife roller 131 and a first supporting roller 132, the first composite material strip can pass through the first supporting roller 132, and the first vacuum knife roller 131 performs roll cutting on the first composite material strip passing through the first supporting roller 131 to form a functional area and adsorb the waste material formed by cutting.

The first vacuum knife roll 131 and the first support roll 132 are driving rolls, and the first composite tape can pass through the space between the first vacuum knife roll 131 and the first support roll 132, and the side of the upper frame tape 21 faces the first vacuum knife roll 131. After the roll cutting, the upper frame material belt 21 is cut to remove a part, that is, the cutting waste is adsorbed on the first vacuum knife roller 131 and taken away from the first composite material belt along with the rotation of the first vacuum knife roller 131.

Specifically, the first vacuum knife roll 131 may be divided into a negative pressure region and a positive pressure region along the circumferential direction, and the upper frame material tape 21 may be rolled in the negative pressure region; the cutting scraps are adsorbed to the negative pressure region and released as the first vacuum knife roll 131 is transferred to the positive pressure region with its rotation. In addition, the first vacuum cutter roll 131 may be controlled to perform evacuation and vacuum breaking as a whole. When the upper frame material tape 21 is cut, the first vacuum knife roll 131 is vacuumized, and when the cutting waste needs to be discharged, the first vacuum knife roll 131 is vacuumized.

Further, in this embodiment, the first discharging device 100 further includes a recycling mechanism 140, the recycling mechanism 140 includes an unwinding shaft 141, a winding shaft 142 and an intermediate roller 143, the waste adhesive tape is unwound by the unwinding shaft 141 and is wound by the winding shaft 142 after being reversed by the intermediate roller 143, and the intermediate roller 143 can support the waste adhesive tape against the first vacuum knife roller 131.

Specifically, the waste tape wound around the intermediate roller 143 has a sticky side outward. When the cutting waste is transferred to the side toward the intermediate roller 143 as the first vacuum cutter roller 131 rotates, the first vacuum cutter roller 131 releases the cutting waste, and the waste tape can stick the cutting waste. Along with the waste discharge adhesive tape is rolled, continuous waste discharge is realized, and waste scattering is effectively avoided.

It should be noted that in other embodiments, the recycling mechanism 140 may recycle the cut waste in other manners. For example, the recycling mechanism 140 includes a first waste bin disposed below the first vacuum roll 131. When the cutting waste generated by cutting the upper frame material belt 21 is transferred to the lower side along with the rotation of the first vacuum knife roller 131, the first vacuum knife roller 131 breaks vacuum to enable the cutting waste to fall off from the first vacuum knife roller 131 and fall into the first waste box by means of inertia and gravity.

The second discharging device 200 is used for sequentially providing a plurality of CCM sheets 23, and a support film sheet is attached to one side of each CCM sheet 23. The frequency of the CCM chips 23 provided by the second emptying device 200 is adjustable, so that the interval between two adjacent CCM chips 23 matches with the interval between two functional areas on the first composite tape, that is, when the CCM chips 23 are attached to the upper frame tape 21 in the first composite tape, the catalyst layers of the CCM chips 23 are attached to the functional areas of the upper frame tape 21.

In this embodiment, the second discharging device 200 includes a CCM discharging reel 210, a second transfer film tape discharging reel 220, a second combining mechanism 230, a cutting mechanism 240, and a drawing mechanism 250. Wherein:

the CCM unreeling shaft 210 is used for storing and unreeling a CCM material belt, and one side of the CCM material belt is covered with a support film. The CCM material belt is composed of a continuous proton membrane material belt and catalyst layers coated on two sides of the proton membrane, and the catalyst layers can be continuously coated or zebra coated. The support membrane plays a protective role, the catalyst layers on two sides of the proton membrane can be prevented from being damaged in the storage and unreeling processes, and meanwhile, the CCM material belt is prevented from being wrinkled. The support film in this embodiment is tacky and will not move relative to the CCM strip during transport, so it does not need to be torn off. The second transfer film tape unwinding shaft 220 is used to store and unwind the second transfer film tape. And the second transfer film material belt is made of the same material as the first transfer film material belt.

The second combining mechanism 230 receives and combines the second transfer film tape and the CCM tape to obtain a second composite tape. Wherein, support the membrane material area centre gripping between CCM material area and second transfer membrane material area. The second combining mechanism 230 may combine the second transfer film material tape and the CCM material tape by a rolling method, or combine the second transfer film material tape and the CCM material tape by an electrostatic adsorption method.

The cutting mechanism 240 cuts the second composite tape and cuts the CCM tape and the support film to obtain a plurality of CCM sheet materials 23 and support film sheet materials arranged along the extending direction of the second transfer film tape. The cutting mechanism 240 may use two oppositely disposed cutting rollers to roll cut the second composite tape. The cutting mechanism 240 cuts only the CCM web and the support film, and does not cut the second transfer film web. Therefore, the plurality of CCM sheets 23 and the support film sheets obtained by cutting can still be attached to the second transfer film material tape, and the second transfer film material tape is transported along with the second transfer film material tape as a support carrier.

The pulling mechanism 250 is capable of pulling the second composite tape to peel the CCM sheet 23 and the support film sheet from the second transfer film tape. Specifically, the second composite tape cut by the cutting mechanism 240 can be conveyed toward the laminating device 300 along a first direction, and the traction mechanism 250 pulls the second composite tape along a second direction.

Since the CCM sheet 23 and the second transfer film tape have a certain rigidity, when the pulling mechanism 250 pulls the second composite tape in a second direction different from the first direction, a force is generated between the CCM sheet 23 and the second transfer film tape to force them away from each other. When the adhesive force of the second transfer film material tape is insufficient to resist the above-described force, the CCM sheet 23 is separated from the second transfer film material tape together with the support film sheet, thereby forming a peel angle. After the CCM sheet 23 is peeled off, it can be continuously conveyed in the first direction toward the laminating apparatus 300. The traction mechanism 250 can peel off the CCM sheet 23 from the second transfer film material belt by using the difference of material properties, and the structure and the flow are simple. Moreover, the peeling process does not need to be brought into contact with the CCM sheet 23, and damage to the CCM sheet 23 can be avoided.

The third discharging device 300 is used for conveying a third composite material belt, which includes a third transfer film material belt and a lower frame material belt 22 attached to the third transfer film material belt. The third transfer film material belt has the same material and effect as the first transfer film material belt and the second transfer film material belt, and plays a role in supporting and protecting. Moreover, the lower frame material belt 22 and the upper frame material belt 21 may be the same frame material belt, or different frame material belts may be selected according to the process.

The third loading device 300 has the same structure as the first loading device 100, and thus, the detailed description thereof is omitted.

Referring also to fig. 2, the laminating device 400 is configured to receive the first composite tape, the CCM sheet 23 and the third composite tape. The bonding apparatus 400 includes an adsorption roller 430, a first pressing roller 410, and a second pressing roller 420. The adsorption roller 430, the first compression roller 410 and the second compression roller 420 are generally driving rollers, and the adsorption roller 430 can adsorb and release materials by vacuumizing or breaking vacuum. There is a gap between the first and second

pressing rollers

410 and 420, i.e., a pressing channel is not formed between the first and second

pressing rollers

410 and 420.

The adsorption roller 430 can receive the CCM sheet 23. Specifically, the CCM sheet 23 separated from the second transfer film supply tape is adsorbed by the adsorption roller 430 one by one, and the side of the CCM sheet 23 provided with the support film sheet is in direct contact with the surface of the adsorption roller 430. With the rotation of the adsorption roller 430, the plurality of CCM sheets 23 on the second transfer tape may be sequentially peeled off and transferred to the next process.

Specifically, in the present embodiment, the adsorption roller 430 can rotate at a constant speed with a preset first linear speed, and the traction mechanism 250 can perform traction at the first linear speed and a second linear speed smaller than the first linear speed.

When it is necessary to transfer the CCM sheet 23 on the second transfer film to the adsorption roller 430, the second composite tape is pulled by the pulling mechanism 250 at the first linear speed to be synchronized with the adsorption roller 430, and the CCM sheet 23 is gradually transferred onto the adsorption roller 430. After the previous CCM sheet 23 is transferred, the drawing mechanism 250 is decelerated to the second linear velocity (the second linear velocity may be 0), and the adsorption roller 430 is rotated at the original velocity. After a preset time interval, the drawing mechanism 250 is again accelerated to the first line speed to transfer the next CCM sheet 23 to the adsorption roller 430. The speed difference between the drawing mechanism 250 and the suction roller 430 enables a desired spacing between two adjacent CCM sheets 23 transferred to the suction roller 430. By repeating the above-described process, CCM sheets 23 having a stable pitch can be obtained on the adsorption roller 430.

After passing through the first press roller 410, the first composite material output by the first discharging device 100 can pass through the gap between the first press roller 410 and the second press roller 420 and pass through the second press roller 420. The first composite tape is pressed against the CCM sheet 23 adsorbed on the adsorption roller 430 at the first pressing roller 410, and is attached to the third composite tape wound around the second pressing roller 420 at the second pressing roller 420.

Specifically, a rolling channel is formed between the first pressing roller 410 and the adsorption roller 430, and the CCM sheet 23 adsorbed on the adsorption roller 430 and the first composite material belt can be combined by rolling in the rolling channel, so that the CCM sheets 23 are sequentially transferred to the first composite material belt. Since the bonding force between the CCM sheet 23 and the support film is smaller than the bonding force between the CCM sheet 23 and the upper frame belt 23 after the roll pressing, the support film sheet will be separated from the CCM sheet 23 and remain adsorbed on the adsorption roller 430.

In order to prevent the support film sheet from scattering on the adsorption roller 430, the laminating apparatus 400 in the present embodiment further includes a second waste cassette 440 for receiving the support film sheet, the second waste cassette 440 being located below the adsorption roller 430. When the support film web rotates to the lower portion with the adsorption roller 430, the adsorption roller 430 releases the support film web, so that the support film web falls into the second waste bin 440 by inertia and gravity.

Further, a third composite material strip output by the third discharging device 300 directly contacts the second pressing roller 420, and the third transfer film material strip faces the second pressing roller 420; the first composite material tape bonded to the CCM sheet 23 at the first pressing roller 410 is wound around the first pressing roller 410 and the second pressing roller 420 in an S-shape, and is not directly contacted with the second pressing roller 420. Further, the side of the first composite tape to which the CCM sheet 23 is attached faces the second press roller 420, and overlaps with the third composite tape on the second press roller 420.

The first and third composite strips will complete the initial application on the second press roll 420. Specifically, the first press roller 410 and the second press roller 420 have wrap angle supportability. When the first and third composite tapes pass around the second press roller 420, an inward wrapping force is formed. Under the effect of the covering force, the third composite material belt is initially attached to the first composite material belt. In addition, unlike roll lamination, the first and third composite tapes are not rolled by the first and

second rollers

410 and 420 during lamination, and only initial lamination is achieved by tape tension. Therefore, the first composite material belt and the third composite material belt can keep tensioning in the laminating process, so that air between the first composite material belt and the third composite material belt can be effectively discharged, wrinkles are avoided, and roll-to-roll continuous laminating is achieved.

At this time, the upper frame material belt 21 and the lower frame material belt 22 are combined with the CCM sheet material 23 to complete the formation of the five-in-one material belt 20. Meanwhile, a first transfer film material strip and a third transfer film material strip are respectively covered on two sides of the obtained five-in-one material strip 20, and the first transfer film material strip and the third transfer film material strip are respectively used as protective films 24 on two sides of the five-in-one material strip 20 and jointly form a fourth composite material strip.

In the case where the curing adhesive applied to the upper frame material tape 21 and the lower frame material tape 22 is a heat-sensitive adhesive, the first press roller 410 and the second press roller 420 both use heating rollers. By heating, the heat-sensitive adhesive on the upper frame material tape 21 and the lower frame material tape 22 can be activated, thereby facilitating the attachment.

When the five-in-one molding apparatus 10 molds the five-in-one material tape 20, the first discharging device 100, the second discharging device 200, and the third discharging device 300 only need to discharge at a fixed frequency, so that the five-in-one material tape 20 can be continuously molded. And go up frame material area 21, lower frame material area 22 and CCM sheet stock 23 all shaping in same equipment, produced error all can make statistics of and control during each material preparation, consequently, when laminating device 400 finally pastes, just can conveniently adjust the error to improve the laminating precision, in order to promote product quality and performance.

In this embodiment, the bonding apparatus 400 further includes an elastic roller 450, and the elastic roller 450 can press the fourth composite material belt against the second pressing roller 420. After the first composite material tape and the third composite material tape pasted with the CCM sheet 23 are pre-pasted on the second pressing roller 420, the adhesion between the first composite material tape and the third composite material tape is still weak. Therefore, the bonding strength between the first composite tape and the third composite tape can be enhanced by further rolling of the elastic roller 450.

In this embodiment, the five-in-one molding apparatus 10 further includes a cooling pressing device 600 and a winding device 700, and the fourth composite material tape can pass through the cooling pressing device 600 and be wound by the winding device 700.

Specifically, the fourth composite material strip output by the laminating device 400 enters the cooling and laminating device 600 to complete cooling and curing. The cooling and laminating apparatus 600 includes thin belts and very closely spaced rollers arranged to provide continuous rigid transfer cooling lamination, thereby providing a tighter adhesion between the layers of the fourth composite material belt. Because the fourth composite material area may lead to the temperature higher because of being heated in forming process, thereby can take place uncontrollable deformation and lead to the fourth composite material area to appear the fold if natural cooling. Cooling compression fittings 600 can carry out meticulous regulation and control to the temperature for the deformation of fourth composite material area in the cooling process is controllable, thereby avoids the fold to produce. The cured fourth composite material tape is wound and stored by the winding device 700 for the next process.

Further, in this embodiment, the five-in-one molding apparatus 10 further includes a visual detection device 800 and a marking device 900, which are located between the cooling and pressing device 600 and the winding device 700, where the visual detection device 800 is configured to obtain an alignment precision of the fourth composite material tape, and when the alignment precision meets a preset condition, the marking device 900 forms a mark on the fourth composite material tape.

Specifically, the vision inspection device 800 may employ a CCD camera module, and the marking device 900 may employ a laser engraving device. If the visual inspection device 800 detects that the alignment precision error between the layers of the fourth composite material tape is too large, the marking device 900 marks the fourth composite material tape.

Referring to fig. 3, in the five-in-one molding apparatus 10 according to the second embodiment of the present invention, the second feeding device 200 includes a CCM feeding shaft 210, a second transfer film feeding shaft 220, a second combining mechanism 230, a cutting mechanism 240, a drawing mechanism 250, a back film winding shaft 260, and a back film feeding shaft 270. Wherein:

the CCM unwinding shaft 210, the second transfer film tape unwinding shaft 220, the cutting mechanism 240 and the drawing mechanism 250 have the same structure and function as those of the previous embodiment, and thus, no further description is provided herein. The differences are as follows: in this embodiment, the support film attached to one side of the CCM carrier tape has no viscosity, and a position deviation and wrinkles may occur between the CCM carrier tape and the support film during transportation, so that the support film needs to be torn off and the adhesive support film with viscosity is attached before the second composite carrier tape is prepared.

Specifically, the back film take-up reel 260 takes up the support film to peel the support film; the backing film unwinding shaft 270 unwinds the adhesive support film. After the CCM material area was opened a book, by the support membrane of notacoria rolling axle 260 separation and rolling non-adhesive, the notacoria was put the spool 270 and is unreeled viscidity and support the membrane simultaneously, and second combined mechanism 230 supports the membrane with the CCM material area with viscidity and compounds. Then, the second combining mechanism 230 combines the CCM tape combined with the adhesive support film with the second transfer film unwound by the second transfer film tape unwinding shaft 220 to obtain a second composite tape.

In other embodiments, the backing film unwinding shaft 270 may also unwind a common support film, and the second composite mechanism 230 may enable the support film to generate electrostatic adsorption force through the electrostatic generator, that is, the support film is composited with the CCM tape after having a certain viscosity.

Referring to fig. 4, in the third embodiment of the present invention, the second discharging device 200 includes a CCM discharging shaft 210 and a cutting and conveying mechanism 280. The CCM unreeling shaft 210 is used for storing and unreeling a CCM material belt, and one side of the CCM material belt is covered with a support film. Further, the support film in this embodiment has adhesiveness, and thus does not need to be peeled off, as in the first embodiment.

The difference from the first embodiment is that: the cutting and conveying mechanism 280 receives the CCM material tape and cuts the CCM material tape into CCM sheet stock 23 having one side to which the support film sheet stock is attached, and conveys the CCM sheet stock 23 to the adsorption roller 430.

Specifically, the cutting conveyor 280 may include a conveyor belt and a cutter assembly. The CCM material belt unreeled by the CCM unreeling shaft 210 can be carried on the conveyer belt and transferred along the conveyer belt. The conveyer belt can be as supporting to make the cutter unit accomplish the cutting smoothly to the CCM material area, the event need not at the compound transfer film material area of one side of CCM material area. The CCM sheet 23 obtained by cutting may be carried on the CCM sheet 23 on the conveyor belt, and the plurality of CCM sheets 23 are sequentially transferred to the adsorption roller 430 by the conveyor belt.

Further, in the present embodiment, the frequency at which the cutting conveying mechanism 280 conveys the CCM sheet 23 to the adsorption roller 430 is adjustable. The rotation speed of the adsorption roller 430 is constant, so the higher the frequency of conveying the CCM sheet 23 by the cutting and conveying mechanism 280, the smaller the distance between two adjacent CCM sheets 23 transferred onto the adsorption roller 430; and the lower the frequency at which the CCM sheet 23 is conveyed by the cutter conveyor mechanism 280, the larger the pitch between adjacent two CCM sheets 23 transferred onto the suction roller 430. By adjusting the frequency of the cutting and conveying mechanism 280 in this manner, CCM sheets 23 having a stable pitch can be obtained on the suction roller 240.

The five-in-one molding apparatus 10 can continuously bond the sheet to the roll and the roll to the roll by using the bonding device 400, so that the first discharging device 100, the second discharging device 200 and the third discharging device 300 only need to discharge at a fixed frequency, and the five-in-one molding apparatus 10 can continuously mold the five-in-one material belt. Moreover, because of the continuous forming process, the CCM sheet 23, the upper frame material belt 21 and the lower frame material belt 22 can be simultaneously attached in the attaching device 400, thereby avoiding pretreatment of a plurality of materials in different devices. The bonding apparatus 400 can facilitate adjustment of an error in final bonding, and can effectively reduce a final bonding error. Therefore, the above five-in-one forming apparatus 10 can improve the forming efficiency of the five-in-one material belt and improve the alignment precision of the five-in-one material belt.
