For reference, the electrolyte layer may be already bonded to the cathode layer or the anode layer, then handled as one body and placed on the sub gasket 10.

Meanwhile, when making the assembly 20, which is a single body structure, by placing and bonding the cathode layer, electrolyte layer, and anode layer in the hole 11 area of the sub gasket 10, a hot-press roller was conventionally used. ) method was applied. That is, after applying adhesive in advance to one side of the cathode layer, electrolyte layer, and anode layer, they are bonded into one body while passing through a hot press roller.

However, when manufacturing the assembly 20 by placing the cathode layer, electrolyte layer, and anode layer in the hole 11 area of the sub gasket 10 as in the prior art and then bonding them through the action of a simple roller, the sub gasket 10 ) Due to the thickness of the hole 11, there is a high possibility that a gap will occur between the materials of the cathode layer, electrolyte layer, and anode layer, and this may cause a problem in that the uniformity of bonding adhesion may be reduced.

Referring to these drawings, the fuel cell manufacturing system according to this embodiment is an anode layer, an electrolyte layer, and an anode layer through the hole 11 of the sub gasket 10. When carrying out the process of manufacturing the assembly 20 by bonding the cathode layer, a gap occurs between the materials (cathode layer, electrolyte layer, anode layer) as before, thereby reducing the uniformity of the bonding adhesion. This deterioration can be prevented, thereby contributing to improving the quality of battery products.

The fuel cell manufacturing system according to the present embodiment that can provide such effects includes a sub-gasket supply device 500, a gasket hole forming device 100, and an overlap zone welding device 200, as schematically shown in FIGS. 5 and 6. ), an active zone main welding device 300, and an assembly separation device 400. These devices are sequentially placed on the line supplied to the process as the sub gasket (10) is released, that is, inline, and proceed with a continuous process, so that the above-described assembly (20) can be formed. do.

As briefly mentioned earlier, the cathode layer, electrolyte layer, and anode layer must be bonded on the surface between each layer, but the cathode layer, electrolyte layer, and anode layer are fragile due to their material characteristics, that is, due to their thickness and material characteristics. , taking this into account, a sub gasket (10) made of polymer film is used. At this time, the state or structure in which the cathode layer, electrolyte layer, and anode layer are bonded to the hole 11 of the sub gasket 10 is called an assembly 20.

At this time, when the assembly 20 is manufactured by placing the cathode layer, electrolyte layer, and anode layer in the hole 11 area of the sub gasket 10 as in the prior art, and then bonding them through the action of a simple roller (not shown), Due to the thickness of the sub gasket 10 and the hole 11, there is a high possibility that a gap will occur between the materials of the cathode layer, electrolyte layer, and anode layer, and this may reduce the uniformity of bonding adhesion.

Therefore, in this embodiment, the cathode layer, electrolyte layer, and anode layer are placed in the hole 11 area of the sub gasket 10 as shown in FIG. 3b, and then bonded as shown in FIG. 3c, but the overlap zone welding device 200 ), the overlap zone (Overlap Layer Zone, OL Zone), which is the edge of the sub gasket 10, is tack-welded, and then complete main welding is performed using the active zone main welding device 300.

In particular, the active zone main welding device 300 first completely welds the active area zone (AA Zone), which is the area of the hole 11 of the sub gasket 10, through the active zone bonding roller 320, Next, the overlap zone (OL Zone) is completely welded in the second step through the overlap zone bonding roller 340.

In other words, in the case of this embodiment, after tack welding the overlap zone (OL Zone), which is the edge portion of the sub gasket 10, using the overlap zone tack welding device 200, the active zone of the active zone main welding device 300 The active zone (AA Zone), which is the hole 11 area of the sub gasket 10, is first completely welded using the bonding roller 320, and then the overlap zone bonding roller 340 of the active zone main welding device 300 is used. By proceeding with the process so that the overlap zone (OL Zone) is completely welded in the second stage, it is possible to prevent the uniformity of bonding adhesion from deteriorating. Therefore, the quality of the product can be significantly improved.

Hereinafter, the configurations of the fuel cell manufacturing system according to this embodiment schematically shown in FIGS. 5 and 6 will be sequentially described.

As shown in FIG. 6, the sub gasket supply device 500 processes the sub gasket 10 to manufacture the assembly 20, which is formed as one body by bonding the cathode layer, the electrolyte layer, and the anode layer. It plays a role in supplying.

This sub gasket supply device 500 includes an unwinder 510 that unwinds and supplies the web-shaped sub gasket 10 to the process, and a sub gasket disposed on the process line and unwinded from the unwinder 510. It includes a plurality of guide rollers 520 that guide (10).

Of course, in addition to the guide roller 520, there is a drive roller (not shown) that holds and pulls the sub gasket 10, a meander stopper (not shown) that prevents the meandering of the sub gasket 10, and the loosening amount of the sub gasket 10. The sub gasket supply device 500 may be further equipped with a sensor (not shown) to detect the gasket, but details about this will be omitted.

As shown in FIGS. 5 to 7, the gasket hole forming device 100 is disposed between the sub gasket supply device 500 and the overlap zone welding device 200, and forms holes 11 on the sub gasket 10. plays a role in forming holes. The gasket hole forming device 100 may be a type of punch structure. The cathode layer, electrolyte layer, and anode layer can be bonded through the hole 11 formed on the sub gasket 10 to form one assembly 20.

Before explaining the overlap zone welding device 200 and the active zone main welding device 300, let's first look at the assembly separating device 400. The assembly separating device 400 is an active zone as shown in FIGS. 5 and 6. It is placed behind the process of the main welding device 300 and serves to separate the assembly 20 formed after the welding process is completed.

In this embodiment, the assembly separation device 400 is applied as a gasket cutter 400 to cut the continuous sub gasket 10 into unit sizes. By the gasket cutter 400, continuous sub gaskets 10 on a web can be cut into unit sizes together with one assembly 20.

Of course, it is possible to remove only the assembly 20 from the sub gasket 10 without using the gasket cutter 400, that is, without cutting the entire continuous sub gasket 10 on the web. This structure Again, it may be included in the assembly separation device 400.

Meanwhile, the overlap zone welding device 200 is disposed on one side of the process line where the sub gasket 10 is supplied, as shown in FIGS. 5 and 6, and aligns each of the cathode layer or anode layer to which the electrolyte layer is attached ( After aligning and placing it in the hole 11 area of the sub gasket 10, the overlap zone (OL Zone), which is the edge of the sub gasket 10, is tack-welded so that the cathode layer, electrolyte layer, and anode layer are tack-welded. It plays a role.

In addition, the active zone main welding device 300 is disposed behind the process of the overlap zone welding device 200, as shown in FIGS. 5 and 6, and is located in the active zone (AA), which is the area of the hole 11 of the sub gasket 10. The assembly 20 as shown in Figure 3a is manufactured by main welding (bonding or lamination) of the zone.

In this way, unlike the prior art, the fuel cell manufacturing system according to this embodiment uses an overlap zone tack welding device 200 and an active zone main welding device 300. Due to the application of these devices 200 and 300, materials (cathode layer, electrolyte) are used as before. It is possible to prevent the uniformity of bonding adhesion from deteriorating due to the occurrence of a gap between the layers and the anode layer, thereby contributing to improving the product quality of the battery.

First, let's take a closer look at the overlap zone welding device 200. 5 to 15, the overlap zone welding device 200 is disposed on one side of the process line where the sub gasket 10 is supplied, and aligns each of the cathode layer or anode layer to which the electrolyte layer is attached. After being placed in the hole 11 area of the sub gasket 10, the overlap zone (OL Zone), which is the edge of the sub gasket 10, is tack-welded to tack-weld the cathode layer, electrolyte layer, and anode layer. do. In other words, through the overlap zone tack welding device 200, the cathode layer, electrolyte layer, and anode layer are tack-welded without separation to form one body. Of course, the strength of bonding is weak. At this time, the electrolyte layer is considered to have been previously bonded to one of the cathode layer and the anode layer.

The overlap zone welding device 200 is arranged in pairs on both sides with the sub gasket 10 in between. Of the pair of overlap zone welding devices 200, one pre-selects the negative plate and the other pre-selects the positive plate, but only the object is different, and the structure and function are all the same. Therefore, the same reference numerals were assigned.

The overlap zone welding device 200 includes a magazine unit (210, Magazine Unit) in which the cathode layer or anode layer is laminated and stored, an alignment unit (220, Align Unit) that aligns the cathode layer or anode layer, and an alignment unit (220) that aligns the cathode layer or anode layer. It may include a turn turret unit (230) that transfers the cathode layer or anode layer aligned by the unit 220 to the sub gasket 10 and pre-tacks it.

Additionally, in this embodiment, the overlap zone welding device 200 is disposed between the magazine unit 210 and the alignment unit 220, and connects the cathode layer or the anode layer on the magazine unit 210 to the alignment unit 220. It is disposed between the first transfer unit 201 (Transfer Unit), the align unit 220, and the turn turret unit 230, and the cathode layer or anode layer on the align unit 220 is transferred to the turn turret unit 230. ) and further includes a second transfer unit (202, Transfer Unit).

The first transfer unit 201 is a unit that pulls the cathode layer or anode layer using a vacuum chuck, etc. to separate it from the magazine unit 210, and aligns the cathode layer or anode layer by moving upward and to the left. It is placed on the align stage 221 of (220), and the cathode layer or anode layer can be loaded on the align stage 221 through an unchucking process. The second transfer unit 202 also operates in the same manner as the first transfer unit 201.

Looking at the configurations in more detail, the magazine unit 210 forms a place where the cathode layer or the anode layer is stacked and stored. Ultimately, in the case of this embodiment, a single sheet of cathode or anode layer is applied, but unlike the drawing, the cathode or anode layer may be provided in the form of a web rather than a sheet and then cut.

The alignment unit 220 is a means for aligning the cathode layer or anode layer transferred from the magazine unit 210 through the first transfer unit 201.

This alignment unit 220 controls the alignment stage 221 (Align Stage) on which the cathode layer or anode layer is loaded and aligned, and the alignment position of the cathode layer or anode layer loaded on the align stage 221. Includes a camera that takes pictures (222, Camera).

The alignment stage 221 includes a device capable of alignment in plane coordinates. Accordingly, when the first transfer unit 201 loads the cathode layer or the anode layer from the magazine unit 210 onto the alignment stage 221, the camera 222 photographs the alignment mark, and based on this information, the alignment stage By driving 221, the correct position of the cathode layer or the anode layer is determined. Then, since the second transfer unit 202 simply picks up the aligned cathode layer or anode layer and transfers it to the turn turret unit 230, the process is not only convenient, but there is no risk of misalignment.

The turn turret unit 230 transfers the cathode layer or anode layer transferred from the alignment unit 220 through the second transfer unit 202 to the sub gasket 10 and serves to pre-tack.

The turn turret unit 230 includes a unit body 240, a heating loading part 250 that forms a place where the cathode layer or anode layer is loaded and heated while being pressed toward the sub gasket 10, the unit body 240, and the heating unit 230. It is connected to the loading unit 250 and may include a loading pressing unit 260 that pressurizes the heating loading unit 250.

This turn turret unit 230 is a type of transfer unit, and transfers the cathode layer or anode layer, for example, the cathode layer placed on the heating loading unit 250, to the sub gasket 10 to perform tack welding, that is, free tack ( It plays a pre-tack role. That is, when the cathode layer is placed on the heating loading part 250, the cathode layer is chucking using the vacuum hole 252 (vacuum hole, or vacuum chuck) in the stage plate 251 of the heating loading part 250. Afterwards, turn (Trun) 180 degrees so that the cathode layer faces the sub gasket (10). The heating loading unit 250 allows the cathode layer and the sub gasket 10 to adhere to each other through the action of the loading pressurizing unit 260. At this time, as the first heating element 253, for example, a sheath type heater, is built into the heating loading unit 250, heat is transferred to the cathode layer and the sub gasket 10, and this pressing force It causes pre-tack by overheating.

In this embodiment, a pair of heating loading units 250 are provided symmetrically on both sides of the unit body 240. Accordingly, while the cathode layer or anode layer is transferred to the sub gasket 10 from one heating loading unit 250 and tack welded, the cathode layer or anode layer to be worked on may be newly transferred to the other heating loading unit 250. Therefore, productivity can be increased by reducing the tact time.

Looking at the heating loading unit 250 in more detail, the heating loading unit 250 includes a stage plate 251 on which a cathode layer or an anode layer is loaded and a plurality of vacuum holes 252 are formed, and a stage A first heating element 253 is provided in the plate 251 and heats the stage plate 251, and a first insulating plate 254 connected to the loading pressurization unit 260 and providing an insulating function. , It may include a first connection plate 255 connecting the stage plate 251 and the first insulation plate 254.

Since the vacuum hole 252 is formed in the stage plate 251, the cathode layer or the anode layer can be loaded on the loading surface of the stage plate 251 without shaking.

The loading pressure unit 260 is connected to a cylinder 261 provided in the unit body 240, a plate support part 262 supporting the loading plate, and the cylinder 261 and the plate support part 262, and the cylinder 261 ) may include a pressing shaft 263 that pressurizes the plate support 262 by the action of.

For reference, in FIGS. 8 to 12, the overlap zone welding device 200 is shown as moving the cathode layer or the anode layer sequentially, but operations for each unit may be performed simultaneously. In this case, the takt time can be further shortened, contributing to improved productivity.
