BACKGROUND OF THE INVENTION
The present invention relates to a method for handling a sheet-like member of an electric double layer capacitor and a handling apparatus.
[0002]
[Prior art]
As a sheet-like member handling apparatus, there is a suction pad called a non-contact type. This suction pad sucks air or the like from the center of the concave portion formed in the suction portion toward the opening periphery of the concave portion, thereby generating a negative pressure in the concave portion and sucking the sheet-like member ( Non-contacting hand ...

[0003]
On the other hand, in recent years, as various power storage devices (such as a drive power source for an electric vehicle), an application technique of an electric double layer capacitor that can be rapidly charged and has a long charge / discharge cycle life has attracted attention.
[0004]
In the electric double layer capacitor, a positive electrode body and a negative electrode body are stacked with a separator (sheet) interposed therebetween, and the stacked body is immersed in an electrolytic solution and accommodated in a container.
[0005]
[Problems to be solved by the invention]
When stacking the positive electrode body, the negative electrode body, and the separator of such an electric double layer capacitor, the above-described suction pad is used for handling. In this case, the structure of the suction pad 1 as shown in FIG. In addition, there is a problem that the laminated component 2 to be handled is caught in the concave portion 3 formed in the suction portion, and it is likely to be wrinkled or the handling position is easily shifted.
[0006]
In particular, since the separator is a thin sheet, wrinkles are likely to occur, and the occurrence of wrinkles affects the performance of the electric double layer capacitor.
[0007]
An object of the present invention is to provide a handling method and a handling apparatus that solve such problems.
[0008]
[Means for Solving the Problems]
According to a first aspect of the present invention, in the sheet-like member handling method, a negative pressure is applied to the arm-shaped recess by ejecting gas from the center of the arm-shaped recess formed in the suction portion of the suction pad toward the periphery of the opening of the recess. Then, the sheet-like member is sucked and handled through a mesh member disposed on the front surface of the suction portion with a predetermined gap from the opening peripheral portion of the concave portion of the suction portion .
[0009]
In the second invention, the handling method according to the first invention is used for handling a multilayer component of an electric double layer capacitor .
[0010]
3rd invention is a sheet-like member handling device,
At the center of the arm-shaped recess formed in the suction part of the suction pad, there is provided a spout that allows gas to be ejected toward the periphery of the opening of the recess to create a negative pressure in the arm-shaped recess, and a net-like shape is formed in front of the suction part. A member is provided, and a predetermined gap is set between the net-like member and the opening peripheral portion of the concave portion of the suction portion .
[0011]
4th invention uses the handling apparatus which concerns on 3rd invention for the handling of the multilayer component of an electrical double layer capacitor .
[0012]
【The invention's effect】
According to the first and third aspects of the invention , the sheet-like member is not caught in the concave portion of the suction portion, and the sheet-like member can be prevented from wrinkling or the handling position being slipped.
[0013]
Further, the gas ejected from the center of the arm-shaped recess toward the periphery of the opening smoothly passes between the opening periphery of the recess of the adsorption portion and the mesh member, so that negative pressure is appropriately applied to the arm-shaped recess. Is generated.
[0014]
According to the second and fourth inventions , the electric double layer capacitor can be easily assembled and the performance can be improved.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0016]
In FIG. 1, reference numeral 10 denotes a suction pad, and a shallow bowl-shaped recess 12 is formed in the suction portion 11 on the lower surface portion of the suction pad 10.
[0017]
A gas supply port 13 of a predetermined pressure is formed on the upper surface portion of the suction pad 10. Although not shown, the supply port 13 is connected to a pipe for guiding gas from a gas supply source (compressor or the like). The pipe is provided with a flow control valve, a pressure adjustment valve, a shut-off valve, various filters, and the like. The
[0018]
At the center of the bowl-shaped recess 12 of the suction part 11, a nozzle part 15 in which a jet port 14 connected to the supply port 13 through the inside of the suction pad 10 is formed is attached.
[0019]
The ejection port 14 is formed so as to eject a gas having a predetermined pressure from the supply port 13 around the nozzle portion 15 toward the peripheral edge of the opening of the bowl-shaped recess 12 at equal intervals. By ejecting gas from the center of the bowl-shaped recess 12 toward the periphery of the opening, a predetermined negative pressure is generated in the bowl-shaped recess 12.
[0020]
A stainless mesh 16 (corresponding to the mesh 20) as a mesh member is disposed on the front surface of the suction portion 11.
[0021]
The stainless steel mesh 16 is formed in a dish shape having a predetermined depth with a mounting flange portion 17, and the mesh presser 19 and tightening are attached to the mounting seat 18 formed on the outer periphery of the suction pad 10 via the mounting flange portion 17. It is attached by bolts 20.
[0022]
In this case, a predetermined gap t is set between the stainless steel mesh 16 and the opening peripheral portion 21 of the recess 12 of the suction portion 11. In addition, the stainless steel mesh 16 is cut out around the peripheral edge portion 21 of the opening so that the mesh is enlarged.
[0023]
Although not shown, the suction pad 10 is attached to an arm that can move in the three-axis directions of X, Y, and Z.
[0024]
When the sheet-like member 30 is handled by the suction pad 10, a gas (for example, air or inert gas) having a predetermined pressure is ejected from the jet port 14 formed in the nozzle portion 15 at the center of the concave portion 12 of the suction portion 11. ) Toward the opening periphery of the recess 12, and the stainless steel mesh 16 on the front surface of the suction portion 11 is brought close to or in contact with the handling position of the sheet-like member 30.
[0025]
As a result, the negative pressure generated in the recess 12 acts on the sheet-like member 30 through the stainless mesh 16, the sheet-like member 30 is adsorbed, and when the suction pad 10 is raised, the sheet-like member 30 is lifted.
[0026]
In this case, since the stainless steel mesh 16 is disposed on the front surface of the suction portion 11, the sheet-like member 30 is not caught in the concave portion 12 of the suction portion 11, and the sheet-like member 30 is wrinkled or handled. Can be prevented from shifting.
[0027]
Then, after the sheet-like member 30 is conveyed to the set position, when the gas ejection from the jet port 14 is stopped, the sheet-like member 30 is separated from the stainless mesh 16 and can be set at the set position.
[0028]
Next, when the separator (not shown) of the electric double layer capacitor is stacked using the suction pad 10, an inert gas (for example, argon gas) is filled so that the electric double layer capacitor does not come into contact with air. It is performed in a predetermined atmosphere such as a glove box (not shown). Therefore, an inert gas (for example, argon gas) is supplied to the supply port 13 of the suction pad 10 and the inert gas is ejected from the ejection port 14.
[0029]
With such a suction pad 10, the separator of the electric double layer capacitor can be handled without being wrinkled or displaced, and can be appropriately stacked between the positive electrode body and the negative electrode body. As a result, the electric double layer capacitor can be easily assembled and the performance can be improved.
