Referring to fig. 1, a seven-in-one tabletting device 100 according to an embodiment of the present utility model includes a laminating mechanism 110, a punching mechanism 120, a half-cutting mechanism 130 and a separating mechanism 140.

The laminating mechanism 110 is capable of attaching the backing film 10 to one side of the seven-in-one web 20 to obtain the first composite web 30. The backing film 10 can be a material tape made of PET material and has high toughness. The seven-in-one tape 20 includes five-in-one tapes and gas diffusion layers attached to both sides of the five-in-one tapes, the gas diffusion layers typically being carbon paper cut to a desired size. The seven-in-one material strip 20 is formed with a plurality of functional regions arranged at intervals in the length direction, and the reaction gas can chemically react at the functional regions to generate electric power when the fuel cell is operated.

Specifically, the five-in-one material belt comprises an upper frame material belt, a lower frame material belt and a plurality of CCM (CCM, catalyst coated membrane, catalyst/proton exchange membrane assembly) sheets, wherein the plurality of CCM sheets are clamped between the upper frame material belt and the lower frame material belt. The corresponding regions of the upper frame material belt and the lower frame material belt are provided with a plurality of hollowed-out grooves, the catalyst layer of each CCM sheet material is arranged corresponding to the hollowed-out grooves on the upper frame material belt and the lower frame material belt so as to form the functional region, and the gas diffusion layer is arranged corresponding to the functional region.

In the present embodiment, the film laminating mechanism 110 includes a film laminating roller 111 and a driving roller 112, and the carrier film 10 and the seven-in-one material tape 20 can pass between the driving roller 112 and the film laminating roller 111, and the carrier film 10 is attached to the seven-in-one material tape 20 under the pressing of the driving roller 112 and the film laminating roller 111.

The laminating roller 111 and the driving roller 112 can realize continuous compounding of the backing film 10 and the seven-in-one material belt 20 in the process of rotation. The drive roller 112 is also capable of providing a driving force for transporting the first composite web 30 downstream while compounding.

The backing film 10 and the seven-in-one material belt 20 can be combined by electrostatic force, adhesive force and other acting forces. Specifically, in this embodiment, the surface of the backing film 10 is pre-coated with a photosensitive adhesive, and the backing film 10 and the seven-in-one material belt 20 are adhered by the photosensitive adhesive. The photosensitive adhesive, which may be a UV adhesive, can make the bonding between the carrier film 10 and the seven-in-one material tape 20 stronger.

Referring to fig. 2, the first composite material tape 30 may be conveyed in a direction indicated by an arrow, and the first composite material tape 30 output through the laminating mechanism 110 may sequentially pass through the punching mechanism 120, the half-cutting mechanism 130, and the separating mechanism 140. Wherein, the punching mechanism 120 can punch the edge of the first composite material belt 30 to form the runner 301 and the pilot hole 302. The flow channel 301 allows the reaction gas to enter and exit when the fuel cell works, and the pilot hole 302 can be matched with the pilot pin in the next process to position the first composite material belt 30.

The punching mechanism 120 performs punching at positions on both sides of the first composite material tape 30 in the width direction, and corresponds to the positions of the functional areas. When the punching mechanism 120 performs punching, the cutting die penetrates through the backing film 10 and the seven-in-one material belt 20, so that the backing film 10 and the seven-in-one material belt 20 are partially hollowed out, and waste generated by punching can be directly discharged at a station where the punching mechanism 120 is located.

The upstream side of the punching mechanism 120 is also typically provided with a visual positioning mechanism 180, and the visual positioning mechanism 180 can position the center of the first composite strip 30, so that the punching position of the punching mechanism 120 is more accurate.

The half-cut mechanism 130 is capable of half-cutting the first composite web 30 and severing the seven-in-one web 20 to obtain a seven-in-one web 21 that is attached to the web of carrier film 10. Specifically, the die of the half-cutting mechanism 130 cuts only the seven-in-one material tape 20 and does not cut the carrier film 10, so that the carrier film 10 can maintain integrity and continuous conveyance can be realized. When the half-cutting mechanism 130 performs the half-cutting operation, the seven-piece material belt 20 can be cut along the circumferential direction of the functional areas of the seven-piece material belt 20, so that each half-cut seven-piece material 21 contains one functional area.

The half-cut mechanism 130 half-cuts to obtain seven-pieces of stock 21 and will also result in a scrap box 22 attached to the carrier film 10 and disposed about the seven-pieces of stock 21. Wherein the runner 301 is located on the seven-in-one sheet 21 and the pilot hole 302 is located on the waste frame 22. When the half-cutting mechanism 130 performs half-cutting, the uneven surface of the seven-in-one material belt 20 can be avoided due to the supporting effect of the backing film 10, so that the half-cutting precision can be improved, and the dimension stability of the obtained seven-in-one material 21 can be maintained.

In particular, in the present embodiment, the first composite material strip 30 between the punching mechanism 120 and the half-cutting mechanism 130 falls under the action of gravity to form a first buffer area, and the first composite material strip 30 located in the first buffer area has a V-shape. The first buffer area can play a role in isolating tension between the punching mechanism 120 and the half-cutting mechanism 130, and can avoid interference with each other when tension fluctuation of the first composite material belt 30 is caused when the punching mechanism 120 and the half-cutting mechanism 130 work.

Moreover, the first composite material belt 30 forms a first buffer area through self gravity, and the buffer and reversing of the first composite material belt 30 by a roller are not needed in the tension isolation process, so that the damage to the carbon paper on the surface of the seven-in-one material belt 20 caused by the friction of the roller surface can be avoided.

The separation mechanism 140 is capable of separating the seven-in-one sheet 21 from the carrier film 10. The separated seven-piece material 21 can be directly transferred to the next process for processing or storage, while the scrap box 22 remains on the surface of the carrier film 10.

In particular, in the present embodiment, the first composite material strip 30 between the half-cutting mechanism 130 and the separating mechanism 140 falls under the action of gravity to form a second buffer area, and the first composite material strip 30 located in the second buffer area has a V-shape. Likewise, the second buffer area can play a role of tension isolation between the half-cutting mechanism 130 and the separating mechanism 140, so that the mutual interference of the working processes of the two is avoided.

Referring to fig. 1 again, in this embodiment, the separating mechanism 140 includes a peeling roller 141 and a main driving roller 142, and the first composite material tape 30 can pass between the peeling roller 141 and the main driving roller 142 and be conveyed in a first direction under the driving of the main driving roller 142, and during the process that the first composite material tape 30 conveyed in the first direction is conveyed in a second direction around the peeling roller 141, the seven-in-one sheet 21 and the carrier film 10 are separated at the peeling roller 141.

The second direction is a different direction than the first direction. Because the seven-in-one sheet 21 has a certain rigidity, when the carrier film 10 is pulled in the second direction, a force is generated between the seven-in-one sheet 21 and the carrier film 10 to urge them away from each other. When the adhesion between the two is insufficient to resist the above forces, the seven-in-one sheet 21 will separate from the carrier film 10 strip, thereby forming a peel angle. With continued operation of the separation mechanism 140, the seven-piece web 21 on the first composite web 30 will be peeled off in sequence. In the process of peeling off the seven-piece material 21, direct contact with the seven-piece material 21 is not required, so that damage to the seven-piece material 21 in the separation process can be effectively avoided.

Further, the main driving roller 142 can also provide a driving force for conveying the first composite material tape 30, thereby ensuring smooth conveyance of the first composite material tape 30.

It should be noted that, in other embodiments, the separating mechanism 140 may also be a manipulator with a suction cup, where the suction cup is capable of peeling the seven-piece material 21 from the surface of the carrier film 10 under the driving of the manipulator after sucking the seven-piece material 21 on the first composite material tape 30.

Further, in the present embodiment, the seven-in-one tablet manufacturing apparatus 100 further includes a recovery mechanism 150, and the recovery mechanism 150 is capable of pulling the carrier film 10 in the second direction. When the recovery mechanism 150 pulls the carrier film 10 in the second direction, the first composite strip 30, which is wound around the peeling roller 141, is diverted to be conveyed in the second direction, thereby separating the seven-in-one sheet 21 from the carrier film 10 at the peeling roller 141.

Specifically, in this embodiment, the recycling mechanism 150 includes a pull roller 151, a roller blade 152, and a waste bin 153, where the pull roller 151 is capable of pulling the carrier film 10, the roller blade 152 is capable of cutting the carrier film 10 downstream of the pull roller 151, and the waste bin 153 is located below the roller blade 152.

The pull roll 151 generally includes two nip rolls disposed opposite each other, and one of the nip rolls is a drive roll, and the pull roll 151 pulls the carrier film 10 in a second direction to reverse the first composite web 30 output through the peel roll 141. The roller blade 152 is capable of crushing the carrier film 10 and the waste frame 22 thereon and collecting the crushed waste from the lower waste box 153.

It should be noted that, in other embodiments, the recovery mechanism 150 may be a take-up roller that directly takes up the carrier film 10.

In addition, in the present embodiment, the seven-in-one sheet-making apparatus 100 further includes a conveying mechanism 160, and the conveying mechanism 160 is capable of carrying the seven-in-one sheet 21 separated from the material tape of the carrier film 10 by the separating mechanism 140 and conveying the seven-in-one sheet 21. Under the action of the conveying mechanism 160, the obtained seven-in-one sheet 21 can be sequentially transferred to a designated position so as to be convenient for storage or for taking in the next process.

It should be noted that, when the separating mechanism 140 is a manipulator with a suction cup, the conveying mechanism 160 may be omitted, and the manipulator may directly move the seven-in-one sheet 21 to a specified position.

Further, in the present embodiment control, the conveying mechanism 160 includes a plurality of conveying rollers 161 and a vacuum belt 162, the vacuum belt 162 is sleeved on the plurality of conveying rollers 161, and the surface of the vacuum belt 162 is capable of carrying and adsorbing seven-in-one sheets 21. Under the suction action of the vacuum belt 162, the seven-in-one sheet 21 can be prevented from scattering or shifting during conveyance.

In this embodiment, a debonding mechanism 170 is disposed between the half-cutting mechanism 130 and the separating mechanism 140, and the debonding mechanism 170 is used for illuminating the first composite tape 30 to weaken the viscosity of the photosensitive paste.

The photosensitive adhesive can weaken the viscosity after being illuminated by the light of the debonding mechanism 170, and the viscosity of the photosensitive adhesive can be completely relieved according to the requirement. The debonding mechanism 170 generally emits UV curing light. Of course, the curing light emitted by the debonding mechanism 170 may be visible light, electron beam, etc. according to the type of photosensitive adhesive on the surface of the carrier film 10.

After irradiation by the debonding mechanism 170, the adhesion between the carrier film 10 and the seven-in-one sheet 21 is reduced or eliminated. Therefore, it is easier to separate the seven-piece material 21 from the carrier film 10, and damage to the seven-piece material 21 can be avoided.

In the seven-in-one sheet making device 100, the film laminating mechanism 110 can attach the backing film 10 to one side of the seven-in-one material belt 20, so as to obtain the first composite material belt 30, and the backing film 10 plays a supporting role in the punching and half-cutting processes of the punching mechanism 120 and the half-cutting mechanism 130, so that the die cutting precision can be improved. The carrier film 10 is a continuous material tape, and can be continuously conveyed. Under the drive of the backing film 10, the seven-in-one material belt 20 can sequentially pass through the punching mechanism 120, the half-cutting mechanism 130 and the separating mechanism 140, so that continuous sheet making of the seven-in-one sheet 21 is realized. Therefore, the seven-in-one tablet manufacturing apparatus 100 described above can effectively improve efficiency.

Referring to fig. 3 and 4, a seven-in-one tablet manufacturing apparatus 200 according to another embodiment of the present utility model includes a main driving mechanism 210, a punching and trimming mechanism 220, and a cutting mechanism 230.

The main driving mechanism 210 is located between the punching and trimming mechanism 220 and the cutting mechanism 230, and can provide driving force for the seven-in-one material tape 20. The seven-in-one material belt 20 continuously fed is driven by the main driving mechanism 210 to pass through the punching and trimming mechanism 220 and enter the cutting mechanism 230.

The punching and trimming mechanism 220 is capable of forming the flow paths 201 on both side edges of the seven-in-one material web 20 and trimming both sides of the seven-in-one material web 20 to form the profiles on both sides in the longitudinal direction (width direction of the seven-in-one material web 20) of the seven-in-one material web 21. The waste generated by the trimming mechanism 220 can be directly discharged at the station where the trimming mechanism 220 is located. Because the seven-in-one material web 20 can maintain high integrity after the first cut by the punch and trim mechanism 220, it can continue to be transported forward under the drive of the main drive mechanism 210 and fed to the cutoff mechanism 230. The cutting mechanism 230 can cut the seven-segment material tape 20 in the width direction, thereby sequentially obtaining a plurality of seven-segment materials 21. It will be seen that the seven-in-one tablet machine 200 also enables continuous tablet production of seven-in-one tablet 21.

The main driving mechanism 210 can maintain the tension of the seven-in-one material belt 20 in the process of driving the seven-in-one material belt 20 to feed, so that the punching and trimming mechanism 220 can be ensured to smoothly realize die cutting. In particular, in this embodiment, the seven-in-one sheet making apparatus 200 further includes a tension control mechanism 240, the tension control mechanism 240 being located on the upstream side of the punch trim mechanism 220. The tension control mechanism 240 can enable the seven-in-one material strip 20 to maintain a set tension during punching and trimming, thereby further improving the machining accuracy.

In addition, the seven-in-one tablet manufacturing apparatus 200 further includes a second visual positioning mechanism 250 and a second conveying mechanism 260, which have the same structure and function as the visual positioning mechanism 180 and the conveying mechanism 160 in the previous embodiment, and thus will not be described herein.

The seven-in-one tablet manufacturing apparatus 200 described above can not only realize continuous production of five-in-one tablets 21. In addition, other consumables are not needed in the production process, so that materials can be saved and the process is simplified.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
