A high-performance product (electric double layer capacitor) can be efficiently manufactured by means of processing each step of refining and sealing the container. In this case, instead of storing the laminated body in the container after assembly, the container is composed of a set of bottom side part and lid side part,
It is assembled in the state of accommodating the laminated body. That is, the assembly of the container and the accommodation of the laminated body are simultaneously processed, and the accommodation of the laminated body can be properly and easily achieved.

In the fourth aspect of the invention, the bottom portion is sucked by the suction pad by the robot hand, and the concave portion is lifted up from the pallet. Then, it is conveyed to the container assembling table and is placed with the concave portion facing upward. Similarly, with the robot hand, the lid side part is sucked by the suction pad and the concave part is lifted downward from the pallet,
It is transported to the container assembly table. In the meantime, the laminated body is housed in the concave portion of the bottom portion of the assembly table, the lid side portion of the robot hand is covered with the concave portion downward, and the peripheral portion of the concave portion except for one side from which the pair of terminals project is formed. The mating surfaces will be sealed. The bottom part and the lid part that are stacked on the pallet are sucked by the suction pad of the robot hand and the recesses fit together when lifted from the pallet. However, since a means for suppressing the second and subsequent sheets is provided, the bottom side portion and the lid side portion can be accurately conveyed one by one to the assembly table.

In the fifth aspect of the invention, the topmost first sheet stacked on the suction pad of the means for suppressing the second and subsequent sheets is sucked, and the fitting of the recesses to the second sheet is peeled off from one side. The second sheet is held down from the upper side by the lever that is lifted and goes into the lower side of the first sheet.

The surface pressure can always be kept uniform. When the suction pad suctions the first sheet and the lifting mechanism operates to raise the substrate to the initial position, the first sheet is lifted up so that the first sheet is detached from the other side, and the first sheet is recessed. On the other hand, the operation of the link mechanism causes the lever to move from the retracted position to the actuated position to enter the lower side of the first sheet and hold the second sheet from the upper side. When the suction is stopped, the first sheet is separated from the suction pad, and in this state, the transportation of the robot hand is started. When the robot hand lifts the first sheet from the pallet, the lever releases the restraint of the second sheet and returns to the retracted position. By such a series of operations, it is possible to
It is possible to transfer the sheets one by one to the container assembly table.

BEST MODE FOR CARRYING OUT THE INVENTION An example of an electric double layer capacitor will be described with reference to FIG. Reference numeral 10 is a container for accommodating the capacitor body (laminated body) together with the electrolytic solution, 11 is a pair of terminal plates (capacitor electrodes) drawn out of the container 10, and each of the terminal plates 11a and 11b is lightweight and has low resistance. It is formed in a short form.

The capacitor body is formed by alternately stacking the same number of positive electrode bodies and negative electrode bodies with a separator (a porous film made of paper or the like) interposed therebetween. The positive electrode body and the negative electrode body are composed of an electrode sheet having the same structure from a collector electrode and polarizable electrodes (activated carbon electrodes) on both surfaces thereof. These collector electrodes are made of a rectangular metal foil (for example, aluminum foil), and a strip-shaped lead portion is integrally formed on one side of the rectangular plane so as to approach one side. The same poles of each lead part are bundled together, and the terminal plate 1 having a polarity corresponding to this bundled part
1a and 11b are joined.

The container 10 is composed of two container members (a bottom side portion and a lid side portion) which are formed in the same shape from a resin film (for example, an aluminum laminated film) of a flexible material having a laminated structure including a metal layer. When these are combined, the accommodating portion of the laminated body is formed by the concave portions 14 having flat rectangular shapes facing each other.

The capacitor body is housed inside the bottom side portion, and the lid side portion is covered from above. At the peripheral edge of the container 10, three sides are thermally welded (heat-sealed) except one side from which the pair of terminal plates 11 (a part thereof) are drawn out. Container 1
In the case of 0, one side from which the pair of terminal boards 11 protrude can be opened, and the electrolytic solution is injected into the inside through the opening, and after impregnation of the electrolytic solution and electrolytic refining are completed, the excess electrolytic solution is extracted and the vacuum state is established. It is hermetically sealed (the remaining openable side is heat welded).

Regarding the recess 14 of the container 10 (the accommodating portion of the laminated body), four side surfaces that rise from the bottom surface of the recess 14 to the mating surface of each side are provided so as to facilitate the opening of one side through which the pair of terminal plates protrude. Among these, the inclination of the side surface 14a corresponding to one side from which the pair of terminal plates 11 protrude is set to be gentler than the inclinations of the other three side surfaces. In FIG. 1, 13a-
13d represents a heat-welded portion.

The process of manufacturing the electric double layer capacitor is divided into a process of processing outside the glove box and a process of processing inside the glove box. Outside the glove box, a step of forming an electrode sheet (a positive electrode body and a negative electrode body), a step of forming a separator having a predetermined area, a step of forming a pair of terminal plates, a container member (bottom side portion and lid side portion) ) Is created, and so on. Before being carried into the glove box, these constituent materials are sufficiently dried (removed of water etc.) in a vacuum drying furnace.

In the highly dry inert gas atmosphere of the glove box (the dew point temperature is about -60 ° C.), a rectangular laminate is composed of the positive electrode body, the negative electrode body and the separator interposed therebetween. Steps, steps of joining (welding) the terminal plates 11 having polarities corresponding to the lead portions (bundling portions) of the same polarity of the laminated body, step of accommodating the laminated body in the container 10 (accommodation state of the container 10 of the laminated body) Step of assembling), a step of injecting an electrolytic solution from one openable side of the container 10 for accommodating the laminated body, a step of impregnating the electrolytic solution into the laminated body, and an electrolytic refining (electrolysis) of residual moisture and functional groups of the laminated body And the step of sealing one side of the container 10 that can be opened and closed.

Inside the glove box, processing means for each process (such as a welding device and a closable tank) and processing means for carrying a work are installed. Inside the airtight tank, the steps from the injection of the electrolytic solution into the container 10 to the electrolytic refining of the laminate are sequentially performed.

In the impregnation with the electrolytic solution, a process of sucking the inside of the closed tank in a vacuum state and a process of filling the inside of the tank with a highly dry inert gas at normal pressure (returning to atmospheric pressure) , Are alternately repeated. As a result, the electrolyte can be sufficiently distributed in every corner of the polarizable electrode and the separator of the laminate, and the impregnation of the electrolyte can be efficiently processed in a short time.

The electrolytic refining is a treatment for removing residual water and functional groups contained in a polarizable electrode (activated carbon electrode) by electrolyzing it and converting it into CO ₂ gas. Inside the terminal, a pair of terminal boards 11a, 11
A charging / discharging cycle is repeated several times, in which a constant current is supplied during b to charge to a set voltage and then discharged. The CO ₂ gas at that time is sucked to the outside of the glove box from the inside of the closed tank by vacuuming.

The suction pad 38 contacts the uppermost portion (first sheet) of the stack, and when the elastic body 47 is compressed by a predetermined amount, the lowering of the substrate 37 is stopped based on the detection information (output of the sensor 48). The descent (stroke) of the substrate 37 changes according to the number of stacked sheets, but since the compression amount of the elastic body 47 is constant at a predetermined value, the surface pressure at which the suction pad 38 contacts the first sheet (the top of the stack) is reduced. You can always keep it uniform.

A negative pressure is supplied to the suction pad 38, and the first sheet is sucked by the suction pad 38. Then, the lifting mechanism 41
When the board 37 is raised to the initial position by the operation of, the first board is lifted so that the fitting of the recesses 14 is peeled off from one side with respect to the second board, while the lever 55 is retracted by the operation of the link mechanism.

When the suction is stopped, the first sheet is the suction pad 3
8, the robot hand 80 starts to be transported in this state. When the first sheet is lifted from the pallet 34 by the robot hand 80, the lever 55 is released from the restraint of the second sheet and returned to the retracted position.
By such a series of operations, the pallets 34a, 34b are
The container members 60a and 60b can be accurately conveyed to the assembly table of the container 10 one by one.

When the pallet 34 becomes empty, the detection information (outputs of the sensors 73a and 73b and the sensors 75a and 7b) is detected.
5b), an empty pallet 34 supports the container members 60a and 60b in a stacked state.
Or the empty pallet 34 to the container member 60a,
60b is replenished in a stacked state.
