Description

[0001] Fuel cell tapping apparatus [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel cell taping apparatus, and more particularly, to a fuel cell taping apparatus capable of advancing a taping operation while compensating deflection of a unit cell.

A chemical cell is a device that converts energy changes when a chemical change occurs into electrical energy. Generally, a chemical cell puts a substance and an electrolyte which constitute an electrode into a container to perform a chemical reaction.

However, the fuel cell continues to supply hydrogen and oxygen from the outside to generate electric energy continuously. This is similar to burning a mixture of fuel and air into the engine. A chemical cell similar to the combustion of fuel is called a fuel cell.

In other words, a fuel cell refers to a device that directly converts the chemical reaction energy of hydrogen, which is contained in a hydrocarbon-based material such as methanol, ethanol, and natural gas, and oxygen supplied from the outside, into direct electrical energy.

Fuel cells can be classified into various types such as a molten carbonate fuel cell (MCFC), a solid oxide fuel cell (SOFC), a phosphoric acid fuel cell (PAFC) A polymer electrolyte membrane fuel cell (PEMFC), a direct methanol fuel cell (DMFC), and the like.

Each fuel cell has fundamentally the same operating principle. However, the fuel cell may be differentiated according to various conditions such as the type of fuel used, the operating temperature, the catalyst, and the electrolyte.

The polymer electrolyte membrane fuel cell has a higher power density and efficiency than other fuel cells, operates at a lower operating temperature, and has advantages of quick start and response characteristics. As a result, the polymer electrolyte membrane fuel cell can be widely used not only as a power source for transportation such as automobiles, but also as a portable power source for various portable devices, as well as a power source for dispersing necessary for a residential environment.

The fuel cell converts the chemical energy resulting from the oxidation of the fuel directly into electric energy. The oxidation reaction of hydrogen in an anode and the reduction reaction of oxygen in an air electrode (cathode) proceed electrochemically, respectively.

The overall reaction of the fuel cell is the reverse reaction of the electrolysis of water, in which heat and water, including electricity, are produced.

The fuel cell unit cell includes an electrolyte membrane, electrodes (i.e., anode and cathode), a gas diffusion layer (GDL), and a separator. These fuel cell unit cells are stacked to form a fuel cell stack. Hereinafter, the fuel cell stack is referred to as a cell stack assembly (CSA).

On the other hand, in order to manufacture the cell stack assembly, a plurality of sub stacks (for example, 48 layers) must be stacked. This operation can be performed through the fuel cell stacker.

For reference, one sub-stack may be composed of a plurality of unit plates, for example, seven unit cells (ISP) and one cooler, and a plurality of sub-stacks having such a structure, for example, And stacked to form one cell stack assembly.

At this time, since the unit cells must be loaded with each other to form a movement path of the gas, the unit cells can be stacked together while preventing the gas from leaking.

In order to stack the end portions of the unit cells with each other and to seal the unit so as not to leak gas, a tapping operation may be performed on the unit cells. The tape used is attached to both sides of both sides of the unit cell, and the taping directions of the upper and lower sides can intersect with each other. The taping operation for such unit cells can be performed through the fuel cell taping device.

However, existing existing fuel cell taping devices are unable to adequately cope with sagging of the unit cell due to the taping operation by holding both sides of the unit cell, thereby preventing mis-taping There is a problem that the taping quality is deteriorated as a result of occurrence of a miss taping phenomenon or an overcoating phenomenon in which the tapping is further protruded outward in the direction of travel.

On the other hand, when the fuel cell taping apparatus according to the present embodiment has the structure as shown in FIG. 5, it can be constructed in-line and thus can provide many advantages. However, the scope of the present invention is not limited thereto.

For example, although it may be ideal to have a configuration as shown in FIG. 5, only the first taping assembly 110a may be applied. The fuel cell taping device may be constructed by only the combination of the first taping assembly 110a, the first unit cell rotating assembly 150a, the first unit cell flip assembly 160a, and the second taping assembly 110b , All of which are within the scope of the present invention.

Hereinafter, the first unit cell flipping assembly 150a, the first unit cell flip assembly 160a, the second taping assembly 110b, the second unit cell flip assembly 160b And the second unit cell rotating assembly 150b are in-line.

The first taping assembly 110a is a place where the taping operation is performed on both sides of one side of the unit cell 112 (see FIG. 3), and the taping operation is performed on both sides of the second taping assembly 110b It accomplishes. Accordingly, the first taping assembly 110a and the second taping assembly 110b are structurally separated from each other, but the configuration and operation are the same.

The first and second taping assemblies 110a and 110b may include a taping unit 120 and a sag prevention unit 140 as best shown in FIG.

The taping unit 120 serves to perform a taping operation for attaching the tape 115 to one side and the other side of the unit cell 112 as shown in FIG. And serves to prevent sagging of the unit cell 112 during the taping operation.

The taping unit 120 supplies the tape 115 in a roll manner and feeds the supplied tape 115 to one side and the other side of the unit cell 112 Respectively. If the taping unit 120 is applied in a roll manner as in the present embodiment, it is possible to perform a continuous process of the work, thereby improving the productivity.

This taping unit 120 may include a tape feed wheel 121 and a tape affixing roll 122 that interacts with the tape feed wheel 121 to attach the tape 115 to the unit cell 112 have. The pair of tapes 115 may be attached to one surface of the unit cell 112 so that the taping units 120 may be disposed on both sides of the unit cell 112. [ The taping unit 120 may be provided in a unit casing 120a having a door 120b that can be opened and closed.

The tape feeding wheel 121 serves to supply the tape 115 in a roll manner. The tape supply wheel 121 is provided with a wheel drive unit 121a for driving the tape supply wheel 121 to rotate.

A tape supply buffer unit 126 is provided around the tape supply wheel 121. [ The tape supplying buffer unit 126 is provided so that the tape 115 can be replaced without stopping the operation of the apparatus for a long time when the tape 115 on the tape supplying wheel 121 is completely exhausted. The tape supply buffer unit 126 has a structure similar to that of the tape supply wheel 121. [

The tape attaching roll 122 is spaced apart from the tape feeding wheel 121 and presses the tape 115 supplied from the tape feeding wheel 121 to the surface of the unit cell 112, And attaches it to the cell 112.

In order to perform the taping operation while pressing the tape 115 to the surface of the unit cell 112 while the tape attaching roll 122 is rotated, the tape attaching roll 122 must be rotated while maintaining the gap with the tape 115. To this end, an attachment roll rotation pressing portion 123 is provided. The attaching roll rotational pressing portion 123 is connected to the tape attaching roll 122 and serves to rotate or press the tape attaching roll 122. The attachment roll rotation pushing section 123 is a structure in which the drive section 123a and the follower section 123b are engaged and rotated so that the tape affixing roll 122 can be rotated.

The tape 115 fed from the tape feeding wheel 121 is easily transferred to the tape roll 122 and adhered to the surface of the unit cell 112 so that the tape 115 is pulled to the level required in the process State. To this end, a tape tension adjusting section 124 is provided.

The tape tension adjusting portion 124 is provided on a tape supply line connecting the tape supplying wheel 121 and the tape attaching roll 122 to control the tension of the tape 115. [ The tape tension adjusting unit 124 includes a first guide roll 124a provided on the tape feeding wheel 121 side, a second guide roll 124b provided on the tape attaching roll 122 side, Down tension regulating roll 124c provided on the first guide rollers 124a and 124b and a guide 124d guiding the up / down operation of the up / down tension adjusting roll 124c. Thus, the tape 115 from the tape feeding wheel 121 to the tape-adhering roll 122 is stretched due to the up / down operation of the up / down tension adjusting roll 124c, loosened at night or the like Lt; RTI ID = 0.0 > tension < / RTI > On the periphery of the guide 124d, an adjusting member 125e for permitting or restricting the operation of the up / down tension adjusting roll 124c may be provided.

In addition to the tape tension adjuster 124, the slant line travel prevention unit 125 is provided on the tape supply line. The diagonal traveling prevention part 125 is provided on one side of the tape supply line and serves to prevent the tape 115 from running in a diagonal direction. In other words, the oblique running prevention unit 125 prevents the tape 115 fed from the tape feeding wheel 121 from being fed to the tape-adhering roll 122 in a state of being skewed.

Even if the taping unit 120 is implemented with this structure, there is no problem in proceeding the taping operation. However, even if only one tape 115 is attached to the unit cell 112, it is difficult to attach the tape 115 to the unit cell 112 or to peel off the attached state. In order to prevent such a phenomenon, a first tape elastic pressing portion 130a and a second tape elastic pressing portion 130b are provided. The first tape elastic pressing portion 130a and the second tape elastic pressing portion 130b are different from each other only in the position in which they are operated, but are identical in configuration and operation.

The first tape elastic pressing portion 130a may be disposed between the tape supplying wheel 121 and the tape attaching roll 122 as shown in FIG. 7 and may include a tape 115 attached to the unit cell 112 It acts to elastically pressurize. As described above, when the first tape elastic pressing portion 130a is disposed between the tape feeding wheel 121 and the tape attaching roll 122 to elastically press the tape 115, the tape by the tape attaching roll 122 The tape 115 can be adhered to the unit cell 112 well because the tape 115 is resiliently pressed simultaneously with or immediately after the tape 115 is attached.

On the other hand, the second tape elastic pressing portion 130b is disposed behind the taping unit 120, and the tape 115 is peeled off from the unit cell 112 that has been taped by the taping unit 120 So as to pressurize the tape 115 elastically. When the second tape elastic pressing portion 130b is applied as in the present embodiment to elastically press the tape 115 against the unit cell 112 in which the taping operation is completed, the phenomenon in which the tape 115 is naturally peeled off is reduced .

As described above, the first tape elastic pressing portion 130a and the second tape elastic pressing portion 130b are different from each other only in the position where they operate, and the configuration and operation are the same. And they can be arranged in pairs in a manner that the tapes 115 are double-sided.

The first or second tape elastic pressing portions 130a and 130b all include a tape pressing roll 131 for pressing the tape 115 in contact with the tape 115 as shown in Fig. And an elastic body 133 which is connected to the tape pressing roll 131 on the one side and fixed to the supporting table 132 and which gives elasticity to the tape pressing roll 131. [ It is possible to prevent the tape 115 or the unit cell 112 from being damaged by the pressing force because the tape pressing roll 131 is elastically operated by the elastic force of the elastic body 133 and presses the tape 115. [

When the unit cell 112 reaches the second tape elastic pressing part 130b, the tape 115 may be completely attached on the unit cell 112. However, if the unit cell 112 is bubbled on the tape 115, Or whether the tape 115 is attached to the end of the unit cell 112 so as to protrude too much. To this end, the vision unit 171 and the sensing unit 182 may be further provided.

The vision unit 171 serves to confirm whether there is a bubble on the tape 115 on the unit cell 112 where the taping operation is completed. The vision unit 171 can be applied to a camera capable of autofocusing.

The sensing unit 182 senses whether or not the tape 115 on the unit cell 112 having completed the taping operation is projected from the end of the unit cell 112. The sensing unit 182 may be an optical sensor or a laser sensor. The sensing unit 182 may sense whether the tape 115 protrudes from the end of the unit cell 112 by irradiation of light.

Both the vision unit 171 and the sensing unit 182 are connected to the controller 180 of FIG. That is, the signals of the vision unit 171 and the sensing unit 182 are transmitted to the controller 180. Based on the signals, the controller 180 controls the first taping assembly 110a, the first unit cell rotating assembly 150a The operation of the first unit cell flip assembly 160a, the second taping assembly 110b, the second unit cell flip assembly 160b and the second unit cell rotating assembly 150b can be individually or entirely controlled .

The controller 180 performing such a role may include a central processing unit 181 (CPU), a memory 182 (MEMORY), and a support circuit 183 (SUPPORT CIRCUIT).

The central processing unit 181 is configured to process the first taping assembly 110a, the first unit cell rotating assembly 150a, the first unit cell 182a, The first unit cell flip assembly 160b and the second unit cell rotating assembly 150b may be individually or wholly controlled by a variety of industrially applicable devices such as a flip assembly 160a, a second taping assembly 110b, a second unit cell flip assembly 160b, May be one of computer processors.

The memory 182 (MEMORY) is connected to the central processing unit 181. The memory 182 may be a computer readable recording medium and may be located locally or remotely and may be any of various types of storage devices, including, for example, random access memory (RAM), ROM, floppy disk, hard disk, May be at least one or more memories.

In this embodiment, the controller 180 controls the first taping assembly 110a, the first unit cell rotating assembly 150a, the first unit cell flip assembly 150a, and the second unit cell flip assembly 150b based on the signals of the non- The first unit cell flip assembly 160a, the second unit cell flip assembly 160b and the second unit cell rotating assembly 150b individually or wholly, ). ≪ / RTI > Typically, a software routine may be stored in the memory 182. The software routines may also be stored or executed by other central processing units (not shown).

Although processes according to the present invention are described as being performed by software routines, it is also possible that at least some of the processes of the present invention may be performed by hardware. As such, the processes of the present invention may be implemented in software executed on a computer system, or in hardware such as an integrated circuit, or in combination of software and hardware.

On the other hand, if the unit cell 112 is sagged when the taping unit 120 is taped, particularly when the center of the unit cell 112 is sagged downwardly convexly, there is no taping or miss taping that is not properly taped. There is a very high possibility that overcoating phenomenon occurs in which the phenomenon occurs or taping is made to protrude further outward in the traveling direction.

In order to prevent this, the sag prevention unit 140 is applied to the fuel cell taping apparatus according to this embodiment. The sagging prevention unit 140 is disposed below the taping unit 120 and serves to prevent sagging of the unit cell 112 during taping operation by the taping unit 120. [

8, the unit cell 112 may be transferred in a state where both end portions thereof are raised by a plurality of cell rotation support portions 145. In such a structure, the slack prevention unit 140 is disposed between the cell rotation support portions 145 So that deflection of the unit cell 112 can be prevented.

Since a pair of tapes 115 are attached to one side of the unit cell 112, the deflection preventing unit 140 having the structure as shown in FIG. 9 can be arranged in a pair in the lower region of the unit cell 112.

7 to 10, the sag prevention unit 140 includes a supporting stage 141 for supporting the unit cell 112 from below, a stage supporting table 142 for supporting the supporting stage 141, And a stage horizontal driving unit 143 connected to the stage supporting table 142 and driving the supporting stage 141 in a horizontal direction.

The supporting stage 141 serves to support the unit cell 112 from below. At this time, it is preferable that the supporting stage 141 is applied as a base to support the unit cell 112 in an ideal horizontal state.

The stage supporting table 142 is a kind of device box for supporting the supporting stage 141. [ The stage up / down driving unit 144 for up / down driving the supporting stage 141 is connected to the stage supporting table (not shown) 142). ≪ / RTI >

The stage up / down driving unit 144 may include a motor 114a and exercise means (not shown) for driving the supporting stage 141 up / down with the power of the motor 114a, Such a moving means can be mounted on the stage support table 142. [

The stage horizontal driving unit 143 is connected to the stage supporting table 142 and horizontally drives the stage supporting table 142 to thereby horizontally drive the supporting stage 141. [ The stage horizontal driving unit 143 can be applied as a normal linear guide.

When the stage supporting table 142 is placed at the working position by the action of the stage horizontal driving part 143, the stage up / down driving part 144 is operated to move the supporting stage 141 to the dotted line in FIG. 10, The lower portion of the unit cell 112 can be stably supported and supported before the operation. Therefore, the unit cell 112 is prevented from being sagged by the pressing force during the self-sagging or taping operation, and the taping operation can be performed with good quality.

The configuration and operation of the first and second unit cell rotating assemblies 150a and 150b and the first and second unit cell flip assemblies 160a and 160b are the same. Of course, the first and second unit cell rotating assemblies 150a and 150b shown in FIGS. 11 and 12 and the first and second unit cell flip assemblies 160a and 160b are applied to the unit cell 112 may be rotated or flipped, so that the scope of the present invention is not limited to the shape of the drawings.
