Abstract

The invention relates to seven-in-one forming equipment which comprises a first discharging device, a second discharging device, a third discharging device, a bonding device and a debonding device. The debonding device comprises a first debonding mechanism and can illuminate the position, corresponding to the functional area, of the support film material belt output by the third discharging device so as to weaken the viscosity of the photosensitive adhesive. The laminating device can be with five unification material areas, diffusion layer sheet stock and support membrane material area pressfitting to obtain seven unification material areas. The first debonding mechanism is located between the third discharging device and the attaching device, so that before attaching, the viscosity of the photosensitive adhesive at the position of the support film material belt corresponding to the functional area is weakened.

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

The first discharging device 100 is used for providing the five-in-one material tape 20. The five-in-one material belt 20 includes an upper frame material belt, a lower frame material belt, and a CCM (catalyst coated membrane module) sandwiched between the upper frame material belt and the lower frame material belt. The five-in-one material tape 20 output by the first discharging device 100 can enter the attaching device 400 to prepare for attaching. Five unification material strips 20 are formed with the functional area that a plurality of intervals were arranged along length direction, and the catalyst layer of every CCM corresponds the fretwork department setting on frame material strip and the lower frame material strip to form functional area. The reaction gas can chemically react at the functional region to generate electric power when the fuel cell is operated.

In general, the two sides of the five-in-one material tape 20 are generally attached with an initial support film material tape 21 to provide protection for the CCM, so as to prevent the five-in-one material tape 20 from damaging the catalyst layer during the storage and unwinding processes.

Specifically, in the present embodiment, the first discharging device 100 includes a first discharging member 110 and two first winding members 120. The first unwinding member 110 is used for unwinding the five-in-one tape 20, and the two first winding members 120 are respectively used for winding the initial support film tapes 21 on two sides of the five-in-one tape 20 so as to tear the initial support film tapes 21 from the surface of the five-in-one tape 20. Therefore, the gas diffusion layer can be attached to the frame material belt of the five-in-one material belt 20 in the next process.

The second discharging device 200 is used for sequentially providing a plurality of diffusion layer sheets to two sides of the five-in-one material tape 20. The diffusion layer sheets supplied from the second discharging device 200 are fed into the bonding device 400 one by one, and the interval between two adjacent diffusion layer sheets is fixed. One side of the diffusion layer sheet material is coated with a curing adhesive in advance, and the side coated with the curing adhesive faces the five-in-one material belt 20. The same second discharging device 200 may simultaneously supply diffusion layer sheets to both sides of the five-in-one material tape 20, or two second discharging devices 200 may be used to respectively supply diffusion layer sheets to both sides of the five-in-one material tape 20. The diffusion layer sheet may be prepared in advance and stored in the second discharging device 200, or may be prepared in real time by the second discharging device 200.

In this embodiment, the second discharging device 200 includes a second discharging member 210, a second collecting member 220, a glue dispensing mechanism 230, a slicing mechanism 240, and a sheet feeding mechanism 250.

The second unwinding member 210 is used for unwinding the diffusion layer tape. In order to avoid the damage of the diffusion layer material belt in the storage and unreeling processes, a protective film material belt is attached to one side of the diffusion layer material belt. The second rolling-up element 220 is used for rolling up the protective film material belt on one side of the diffusion layer material belt so as to tear off the protective film material belt from the surface of the diffusion layer material belt. The glue dispensing mechanism 230 applies curing glue to the surface of the diffusion layer material tape unreeled by the second unreeling member 210. Specifically, the coated curing adhesive may be a heat-sensitive adhesive or a pressure-sensitive adhesive. The slicing mechanism 240 cuts the diffusion layer material strip to sequentially obtain a plurality of diffusion layer sheets. The sheet feeding mechanism 250 sequentially feeds the diffusion layer sheet obtained by the sheet cutting mechanism 240 to the bonding apparatus 400. The slicing mechanism 240 may cut the diffusion layer material tape by a cutter or a laser cutting method, and the sheet feeding mechanism 250 may adopt a form of a conveyor belt, a nip roller, a clamping jaw, etc., so as to prevent the diffusion layer material tape from deflecting when entering the laminating device 400.

The third discharging device 300 may employ a discharging roller for providing the support film material tape 30 to both sides of the five-in-one material tape 20. And, one side of the support film material belt 30 is provided with a photosensitive adhesive. The photosensitive adhesive is sensitive to light and can reduce or eliminate the viscosity under the irradiation of curing light. For example, the photosensitive adhesive may be a UV viscosity reducing adhesive that reacts to reduce or eliminate viscosity under UV light. The material of the support film material belt 30 may be the same as the material of the initial support film 21, and both can play a role in protection. In this embodiment, two third discharging devices 300 are used to respectively provide the support film material belt 30 to two sides of the five-in-one material belt 20. The support film material belt 30 provided by the third discharging device 300 enters the laminating device 400, and the side provided with the photosensitive adhesive faces the five-in-one material belt 20 and the diffusion layer sheet.

The bonding device 400 is used for receiving and bonding the five-in-one material belt 20, the diffusion layer sheet and the support film material belt 30 to obtain the seven-in-one material belt 101. Specifically, the bonding apparatus 400 can press the five-in-one material tape 20, the diffusion layer sheet, and the support film material tape 30 by a rolling method. Wherein, a plurality of diffusion layer sheet materials are sequentially attached to the functional areas on both sides of the five-in-one material belt 20 to form a seven-in-one material belt 101. Further, the support film material tape 30 is adhered to two sides of the seven-in-one material tape 101 by a photosensitive adhesive to protect and support the seven-in-one material tape 101.

When the bonding apparatus 400 is used for bonding, the diffusion layer sheet 40 is clamped between the support film material belt 30 and the five-in-one material belt 20, so that it is not easily damaged.

As shown in fig. 3 and 4, the seven-in-one material tape 101 includes the five-in-one material tape 20 and a plurality of diffusion layer sheets 40 located at two sides of the five-in-one material tape 20, the diffusion layer sheets 40 are sandwiched between the five-in-one material tape 20 and the support film material tape 30, and the support film material tapes 30 at two sides can be used as a protective film of the seven-in-one material tape 101, so as to protect the diffusion layer sheets 40 at two sides, and prevent the diffusion layer sheets 40 from being damaged during storage and transportation of the seven-in-one material tape 101.

The debonding device comprises a first debonding mechanism 510, and the first debonding mechanism 510 is located between the third discharging device 300 and the attaching device 400. The first de-bonding mechanism 510 can illuminate the position of the support film material tape 30 corresponding to the functional area to reduce the viscosity of the photosensitive adhesive. The photosensitive adhesive can be weakened by the light of the first debonding mechanism 510, and the adhesiveness of the photosensitive adhesive can be completely removed as required.

Referring to fig. 2, in the embodiment, the first debonding mechanism 510 includes a light shielding plate 511 and a curing light source 512. The light blocking plate 511 is formed with a light transmission window 5111. The light-transmitting window 5111 may be a through hole or a region of the light-shielding plate 511 made of a light-transmitting material. The curing light source 512 is typically an ultraviolet light source that emits UV curing light. Of course, the curing light emitted by the curing light source 512 may be visible light, electron beam, etc. according to the type of photosensitive adhesive on the surface of the support film material tape 30.

The light shielding plate 511 is disposed on one side of the support film carrier tape 30, and the curing light source 512 is disposed on one side of the light shielding plate 511 facing away from the support film carrier tape 30. Moreover, the curing light emitted by the curing light source 512 can penetrate through the light-transmitting window 5111 and irradiate the positions of the support film tape 30 corresponding to the functional areas, so that the viscosity of the photosensitive adhesive at the positions of the support film tape 30 corresponding to the functional areas is sequentially weakened.

In this way, the support film tape 30 does not stick to the diffusion layer sheet 40 of the functional region during the formation of the seven-in-one tape 101 by the laminating device 400. The contact area between the support film material belt 30 and the diffusion layer sheet material 40 is small, and the bonding force is weak. Therefore, the seven-in-one material tape 101 is not wrinkled or deformed during the process of tearing the support film material tape 30. Further, the diffusion layer sheet 40 is not broken.

In the present embodiment, the seven-in-one molding apparatus 10 further includes a curing device 600 located downstream of the laminating device 400, the seven-in-one tape 101 can enter the curing device 600, and the curing device 600 can cure the curing glue between the diffusion layer sheet 40 and the five-in-one tape 20.

Specifically, the curing device 600 may perform curing by heating, rolling or a combination thereof according to the type of the curing adhesive. The seven-in-one material tape 101 output by the bonding device 400 is cured by the curing device 600, so that the structures of the layers are combined more tightly.

The seven-in-one material belt 101 can be rolled and stored for the next process. In addition, the seven-in-one forming apparatus 10 may slice the seven-in-one tape 101 to obtain a single piece of seven-in-one sheet 102 as shown in fig. 5. The seven-in-one sheet 102 comprises a five-in-one sheet 20 'and diffusion layer sheets 40 on two sides, and the five-in-one sheet 20' is formed by cutting the five-in-one material belt 20.

Referring to fig. 1 again, in the present embodiment, the seven-in-one forming apparatus 10 further includes a first film tearing device 610 and a die cutting device 700. Wherein:

the first film tearing device 610 is used for tearing off the support film material belt 30 on the upper surface of the seven-in-one material belt 101, so that the upper surface of the seven-in-one material belt 101 is exposed. The first film tearing device 610 may employ a material receiving roller, and since the viscosity of the photosensitive adhesive at the position corresponding to the functional area of the support film material tape 30 is weakened, the process of tearing off the support film material tape 30 on the upper surface will not damage the function of the seven-in-one material tape 101.

Specifically, in this embodiment, the debonding device includes a second debonding mechanism 520 located upstream of the first film tearing device 610, and the second debonding mechanism 520 can illuminate the position, corresponding to the functional area, of the support film material tape 30 located on the upper surface of the seven-in-one material tape 101, so as to reduce the viscosity of the photosensitive adhesive.

The second de-bonding mechanism 520 has the same structure and function as the first de-bonding mechanism 510, and thus is not described herein again. The second de-bonding mechanism 520 is arranged to further weaken the viscosity of the photosensitive adhesive on the surface corresponding to the functional area before the support film material belt 30 on the upper surface is torn off, so that the support film material belt 30 on the upper surface can be torn off more smoothly.

Further, the die cutting device 700 is located downstream of the first film tearing device 610. The die cutting device 700 includes a first die cutting mechanism 710 and a second die cutting mechanism 720 located at the downstream of the first die cutting mechanism 710, and the seven-in-one tape 101 exposed on the upper surface can sequentially enter the first die cutting mechanism 710 and the second die cutting mechanism 720 and be cut.

Specifically, the first die-cutting mechanism 710 can perform die cutting on the seven-in-one material tape 101 from the upper surface to form the gas flow channel on the diffusion layer sheet 40; the second die-cutting mechanism 720 can die-cut the seven-in-one tape 101 from the upper surface and cut the seven-in-one tape 101 to obtain a plurality of seven-in-one sheets 102. The second die-cutting mechanism 720 cuts along the gap between two adjacent functional regions, and does not cut off the lower surface of the support film material belt 30. In this way, the obtained seven-in-one sheet 102 can still be conveyed with the support film material belt 30 on the lower surface.

In the present embodiment, the seven-in-one molding apparatus 10 further includes a carrying device 800 and a second film tearing device 620. Wherein, the conveying device 800 is positioned at the downstream of the die cutting device 700, and the conveying device 800 can sequentially adsorb and transfer the seven-in-one sheet 102.

The transporting device 800 may include a transfer guide and a suction head, and after the suction head sucks the seven-in-one sheet 102, the transfer guide drives the suction head and the sucked seven-in-one sheet 102 to move to the upper side of the storage box 103. The suction head releases the seven-in-one sheet 102 so that the seven-in-one sheet 102 can be placed in the storage box 103. The above process is repeated to stack the seven-in-one sheet 102 in the storage box 103. In addition, the conveying device 800 may also adopt an inverted vacuum conveyor belt, which can absorb the seven-in-one sheet 102 to convey towards the storage box 103, and release the seven-in-one sheet 102 when conveying to the upper side of the storage box 103.

Specifically, in the present embodiment, the seven-in-one forming apparatus 10 further includes a conveyor belt 900 located downstream of the die cutting device 700, and the seven-in-one sheet 102 output by the die cutting device 700 can be carried on the conveyor belt 900. The conveying device 800 can take away the seven-in-one sheets 102 one by one from the surface of the conveyor belt 900, and the conveyor belt 900 can provide better support for the lower surface of the support film material belt 30 and the seven-in-one sheet 102 thereon, so that the conveying device 800 can conveniently suck the seven-in-one sheet 102.

The second film tearing device 620 is used for rolling the support film material belt 30 on the lower surface. Specifically, the first film tearing device 610 may employ a take-up roller. As the seven-in-one sheet 102 is transferred, the lower support film web 30 is gradually emptied. Adopt second dyestripping device 620 in time to roll up and can avoid the scattered falling of vacating support membrane material area 30 to can prevent to support membrane material area 30 and follow seven unification sheet stocks 102 and remove and influence and shift seven unification sheet stocks 102.

Specifically, in the present embodiment, the debonding apparatus includes a third debonding mechanism 530 located upstream of the carrying apparatus 800, and the third debonding mechanism 530 is capable of illuminating a position of the lower surface of the support film material tape 30 corresponding to the functional area to weaken the viscosity of the photosensitive adhesive.

The third de-bonding mechanism 530 has the same structure and function as the first de-bonding mechanism 510 and the second de-bonding mechanism 510, and thus is not described herein again. The third debonding mechanism 530 is provided to further weaken the viscosity of the lower support film tape 30 before the seven-in-one sheet 103 is transferred, so that the conveying device 800 can smoothly move the seven-in-one sheet 102 away from the lower support film tape 30.

In the seven-in-one forming apparatus 10, the laminating device 400 can press the five-in-one material tape 20, the diffusion layer sheet 40 and the support film material tape 30 together to obtain the seven-in-one material tape 101. When the film is adhered, the diffusion layer sheet material 40 is clamped between the support film material belt 30 and the five-in-one material belt 20, and is not easy to be damaged. The outermost side of the seven-in-one material tape 20 is attached with the support film material tape 30, and the diffusion layer sheet material 40 can be prevented from being damaged. The first debonding mechanism 510 is located between the third depositing device 300 and the bonding device, and can illuminate the position of the support film tape 30 corresponding to the functional area, so that the stickiness of the photosensitive adhesive is weakened at the position of the support film tape 30 corresponding to the functional area before bonding, and the support film tape 30 does not adhere to the diffusion layer sheet 40 in the functional area. Therefore, the seven-in-one material tape 101 is not wrinkled or deformed during the process of removing the support film material tape 30, so that the function is prevented from being damaged. The seven-in-one molding device 10 can realize the preparation and the bonding of the gas diffusion layer sheet material 40, and finally complete the preparation of the MEA (membrane Electrode assembly), and has high automation degree and high production precision, thereby greatly improving the production efficiency and the product quality.
