Abstract

A border discharging apparatus (100) and a bonding device. The border discharging apparatus (100) comprises an unwinding mechanism (110) and a debonding mechanism (120). The debonding mechanism (120) can expose a composite material strip (20) provided by the unwinding mechanism (110), so that curing light emitted by a curing light source (122) sequentially irradiates a plurality of functional areas of the composite material strip (20) so as to reduce the viscosity of a photosensitive adhesive in the functional areas. In this way, when a CCM sheet (30) is attached to the composite material strip (20), a transfer film material strip (21) does not adhere to the CCM sheet (30) in the functional areas. Therefore, during the process of tearing off a support film on both sides of a five-in-one material strip, a catalyst layer on the surface of the CCM sheet (30) is not damaged, thereby avoiding functional damage to the five-in-one material strip.

Please refer to FIG. 1 , the utility model provides a bonding device (not shown) and a frame discharging device 100 . Wherein, the bonding equipment includes a frame discharging device 100, a CCM discharging device (not shown in the figure) and a bonding device (not shown in the figure), and the bonding device is used for preparing five-in-one material strips.

The frame discharging device 100 can provide two composite material strips 20, and the CCM discharging device is used to provide multiple CCM sheet materials. Specifically, two composite material strips 20 can be provided by the same frame discharge device 100, or two frame discharge devices 100 can be provided to provide two composite material strips 20 respectively. As shown in FIG. 3 , the composite material tape 20 includes a transfer film material tape 21 and a frame material tape 22 .

The structure and material of the upper transfer film strip and the lower transfer film strip are generally the same, and the upper frame strip and the lower frame strip can be the same frame strip, or different frame strips can be selected according to the process.

As shown in FIG. 4 , in one embodiment, the bonding device is used to sequentially bond multiple CCM sheets between two composite material tapes 20 to prepare a five-in-one material tape 10 .

Specifically, the bonding device can realize roll-to-roll bonding. After the laminating device receives the two composite material strips 20, first a plurality of CCM sheets 30 are sequentially bonded to one of the composite material strips 20 to obtain an intermediate material strip; then, the laminating device combines another composite material strip 20 with the The intermediate material tape is laminated roll-to-roll, and the preparation of the five-in-one material tape 10 can be completed. At this time, two transfer film material strips 21 of the composite material strip 20 are attached to both sides of the five-in-one material strip 10 to serve as supporting films on both sides of the five-in-one material strip 10 respectively.

As shown in Figure 5, in another embodiment, the laminating equipment also includes a slicing device (not shown), and the slicing device cuts the composite material strip 20 along the gap between two adjacent functional areas to obtain multiple A composite sheet 20', and each composite sheet 20' includes a transfer film sheet and a frame sheet.

The bonding device first bonds multiple CCM sheets 30 to one of the composite material tapes 20 to obtain an intermediate material tape; The multiple composite sheet materials 20 ′ obtained by cutting the material tape 20 are sequentially pasted on the CCM sheet material 30 of the intermediate material tape to complete the preparation of the five-in-one material tape 10 . At this time, the transfer film material tape 21 of the composite material tape 20 and the transfer film sheet material of a plurality of composite sheet materials 20' are respectively attached to both sides of the five-in-one group material tape 10.

Apparently, in other embodiments, the bonding equipment can also only perform sheet-to-sheet bonding. Composite material band 20 is cut into a plurality of composite sheet materials 20' by slicing device first, and composite sheet material 20' is all laminated on both sides of each CCM sheet material. In this way, a five-in-one sheet of the transfer film sheet with the composite sheet 20' attached to both sides can be obtained.

Please refer to FIG. 1 again, the frame unwinding device 100 in the preferred embodiment of the present invention includes an unwinding mechanism 110 and a debonding mechanism 120 .

The unwinding mechanism 110 is used to provide the composite material tape 20 , and the composite material tape 20 includes a transfer film material tape 21 and a frame material tape 22 . Further, one side of the transfer film material strip 21 is provided with photosensitive adhesive, and the frame material strip 22 is bonded to the transfer film material strip 21 through the photosensitive adhesive. Photosensitive adhesive is sensitive to light, and its viscosity can be reduced or eliminated under the irradiation of curing light. Specifically, the photosensitive glue can be UV glue, and the viscosity can be weakened by ultraviolet light irradiation. Apparently, the photosensitive adhesive may also be visible light curable adhesive, electron beam curable adhesive, etc., which is not limited here. The transfer film material strip 21 has good toughness and can be used as a support carrier for the frame material strip 22 to be transported. The unwinding mechanism 110 can realize continuous unwinding because the composite tape 20 is supplied in the form of unwinding.

In this embodiment, the unwinding mechanism 110 includes an unwinding component 111 , a composite component 112 and a cutting component 113 . in:

The unwinding assembly 111 includes a transfer film unwinding part and a frame unwinding part, which are respectively used for unwinding the transfer film material tape 21 and the frame material tape 22 provided with photosensitive adhesive on one side. Specifically, the transfer film unwinding part and the frame unwinding part may be two unwinding rollers, which are respectively used for storing the transfer film material tape 21 and the frame material tape 22 and unwinding them. The composite component 112 is located downstream of the unwinding component 111 , and the transfer film strip 21 and the frame material strip 22 unrolled by the unwinding component 111 enter the composite component 112 after being corrected in the width direction. The composite component 112 can composite the transfer film strip 21 and the frame strip 21 to obtain the composite strip 20 . The surface of the frame material belt 22 facing away from the transfer film material belt 21 is generally pre-coated with curing glue to facilitate bonding with the CCM sheet 30. The curing glue can be heat-sensitive glue or pressure-sensitive glue.

Specifically in this embodiment, the composite assembly 112 includes a driving roller 1121, two passing rollers 1122 and a resisting roller 1123. The two passing rollers 1122 and the driving roller 1121 are arranged at intervals, the transfer film material belt 21 and the frame material belt 22 can respectively go around the passing roller 1122 and wrap around the driving roller 1121, and the resisting roller 1123 can hold the transfer film material belt 21 and the frame material The belt 22 is pressed against the driving roller 1121 .

The driving roller 1121 is a driving roller, and the two passing rollers 1122 and the resisting roller 1123 are driven rollers. Before the transfer film material strip 21 and the frame material strip 22 enter the driving roller 1121 , the angles at which they enter the driving roller 1121 can be changed by the two passing rollers 1122 respectively so as to generate wrap angles. Moreover, the tension in the film is improved due to the existence of rigid resistance, and at the same time, because the distance between the two passing rollers 1122 and the driving roller 1121 is relatively close, it is not enough to cause the transfer film material belt 21 and the frame material belt 22 to produce waves in the direction of contraction or extension. . In this way, the transfer film material strip 21 and the frame material strip 22 can be equivalent to a rigid body enveloped on the driving roller 1121 , thereby obtaining better composite quality. In addition, the resisting roller 1123 can isolate the composite tension and roll the transfer film material strip 21 and the frame material strip 22 so that the two can be better bonded.

Apparently, in other embodiments, the transfer film strip 21 and the frame strip 22 can also be directly laminated by two pairs of rollers.

The composite strip 20 is formed with functional areas arranged at intervals along the length direction. Wherein, the frame material strip 22 can be hollowed out in advance to process a functional area, and can be directly compounded with the transfer film material strip 21 after unwinding from the unwinding assembly 111 . In this embodiment, the frame material strip 22 unrolled by the unwinding component 111 does not have a functional area, so the frame material strip 22 needs to be cut to form a functional area. In this way, it is beneficial to save costs, and can improve the compounding precision of the composite material strip 20 and the preparation precision of the five-in-one material strip 10 .

Further, the cutting assembly 113 is located downstream of the composite assembly 112 and is used for cutting the composite material strip 20 to form functional areas arranged at intervals along the length direction on the frame material strip 22 . The composite material tape 20 compounded by the compound assembly 112 can be continuously delivered to the cutting assembly 113, and the cutting assembly 113 only cuts the frame material tape 22 without cutting the transfer film material tape 21, and combines the frame material tape 22 with the The part corresponding to each functional area of the strip 20 is hollowed out, so as to form a functional area on the frame strip 22 .

It should be pointed out that the extending direction of the five-in-one material strip 10 has a plurality of functional areas spaced apart, and when the fuel cell is working, the reactant gas can undergo a chemical reaction at the functional areas to generate electricity. The functional area of the frame material strip 22 , the functional area of the composite material strip 20 and the functional area of the five-in-one material strip 10 overlap.

Specifically in this embodiment, the cutting assembly 113 includes a vacuum knife roll 1131 and a support roll 1132, the composite material tape 20 can be wound around the support roll 1132, and the vacuum knife roll 1131 rolls the composite material tape 20 around the support roll 1132. , so as to form a functional area on the frame material belt 22 and absorb the waste materials formed by cutting.

The vacuum knife roll 1131 and the support roll 1132 are both driving rolls, and the composite material belt 20 can be squeezed between the vacuum knife roll 1131 and the support roll 1132 , and the side with the frame material belt 22 faces the vacuum knife roll 1131 . After roller cutting, the cut part of the frame material belt 22 , that is, the cutting waste is adsorbed on the vacuum knife roller 1131 , and is taken away from the composite material belt 20 along with the rotation of the vacuum knife roller 1131 .

Specifically, the circumferential direction of the vacuum knife roller 1131 can be divided into a negative pressure area and a positive pressure area. The frame material strip 22 can be rolled in the negative pressure area; The rotation of the roller 1131 is transferred to the positive pressure area to be released. In addition, the vacuum knife roller 1131 can also be controlled to vacuumize and break vacuum as a whole. When cutting the frame material strip 22, the vacuum knife roller 1131 vacuumizes, and when it is necessary to discharge cutting waste, the vacuum knife roller 1131 breaks the vacuum.

Further, in this embodiment, the frame unwinding device 100 also includes a recovery mechanism 130. The recovery mechanism 130 includes an unwinding shaft 131, a winding shaft 132, and an intermediate roller 133. 133 is rewound by the winding shaft 132 after reversing, and the intermediate roller 133 can support the waste discharge tape against the vacuum knife roller 1131 .

Specifically, the sticky side of the waste discharge tape winding through the intermediate roller 133 faces outward. When the cutting waste is transferred to the side towards the middle roller 133 along with the rotation of the vacuum knife roller 1131, the vacuum knife roller 1131 releases the cutting waste, and the waste discharge tape can stick the cutting waste. As the waste discharge tape is rewound, continuous waste discharge is achieved, effectively avoiding waste materials from scattering.

It should be noted that, in other embodiments, the recycling mechanism 130 may also use other methods to recycle the cutting waste. For example, the recovery mechanism 130 includes a waste box disposed under the vacuum knife roller 1131 . When the cutting waste produced by the cutting of the frame material belt 22 is transferred to the lower side along with the rotation of the vacuum knife roller 1131, the vacuum knife roll 1131 can release the cutting waste, and the cutting waste falls off from the vacuum knife roll 1131, and Rely on inertia and gravity to fall into the waste box.

Please also refer to FIG. 2 , the debonding mechanism 120 includes a light shielding plate 121 and a curing light source 122 , a light-transmitting window 1211 is formed on the light shielding plate 121 , and the curing light source 122 can emit curing light. The light-transmitting window 1211 can be a through hole, or a region made of light-transmitting material on the light-shielding plate 121 . The curing light source 122 is generally an ultraviolet light source, capable of emitting UV curing light. Wherein, the light-shielding plate 121 is not located on one side of the composite material belt 20, and the curing light source 122 is located on the side of the light-shielding plate 121 facing away from the composite material belt 20, and the curing light emitted can pass through the light-transmitting window 1211 and irradiate the composite material belt sequentially. 20 multiple functional areas to weaken the viscosity of the photosensitive adhesive located in the functional areas. After the photosensitive adhesive is illuminated by the curing light source 122, the viscosity of the photosensitive adhesive can be weakened, and the viscosity of the photosensitive adhesive can also be completely released as required.

Specifically, in this embodiment, the curing light emitted by the curing light source 122 is a light pulse, and the frequency of the light pulse of the curing light source 122 is adjustable. In different types of five-in-one material strips 10 , the distance between two adjacent functional areas is also different. The frequency of the light pulse directly determines the distance between the two illuminations. Therefore, by changing the frequency of the curing light source 122 , the frame discharging device 100 can be adapted to the preparation of different types of five-in-one material strips 10 .

When the CCM sheet material 30 is attached to the composite material tape 20 and the composite sheet material 20' and the five-in-one material tape 10 is obtained, since the photosensitive adhesive in the functional area is weakened, the transfer film material tape 21 and the transfer film sheet material Neither will stick to the CCM sheet 30 in the functional area. Therefore, in the process of tearing off the supporting films on both sides of the five-in-one material strip 10 , the catalyst layer on the surface of the CCM sheet material 30 will not be damaged, thereby avoiding the damage to the function of the five-in-one material strip 10 .

In this embodiment, the debonding mechanism 120 is located between the composite component 112 and the cutting component 113 . The composite material tape 20 output by the compound assembly 112 is shown in (a) in FIG. The cutting component 113 removes the part of the frame material strip 22 located in the functional area to obtain the composite material strip 20 as shown in (c) of FIG. 3 . That is to say, before the composite material tape 20 is cut, the viscosity of the photosensitive adhesive in the functional area of the composite material tape 20 is weakened. In this way, after the composite material tape 20 is cut, the transfer film material tape 21 will not cause adhesion to the cutting waste generated during cutting, so it is beneficial for the cutting waste to be taken away with the vacuum knife roller 1131 .

It should be noted that, in other embodiments, the debonding mechanism 120 may also be disposed downstream of the cutting assembly 113 , that is, after the composite tape 20 is cut, the functional area of the composite tape 20 is illuminated. In addition, for the case where the frame material strip 20 is pre-processed and the functional area is obtained, after the composite component 112 is compounded, the composite material strip 20 is directly illuminated and debonded, and the composite material strip 20 as shown in (c) in FIG. 3 can be obtained. .

The above-mentioned frame unwinding device 100 and laminating equipment, the debonding mechanism 120 can expose the composite tape 20 provided by the unwinding mechanism 110, so that the curing light emitted by the curing light source 122 sequentially irradiates multiple functional areas of the composite tape 20 , to weaken the viscosity of the photosensitive adhesive located in the functional area. In this way, when the CCM sheet is bonded to the composite tape 20 , the transfer film tape 21 will not stick to the CCM sheet 30 in the functional area. Therefore, in the process of tearing off the supporting films on both sides of the five-in-one material tape 10, the catalyst layer on the surface of the CCM sheet will not be damaged, thereby avoiding the damage to the function of the five-in-one material tape 10.

The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, should be considered as within the scope of this specification.

The above-described embodiments only express several implementations of the utility model, and its description is relatively specific and detailed, but it cannot be interpreted as a limitation to the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the scope of protection of the utility model patent should be based on the appended claims.
