Has a substantially rectangular opening. Then, the electrode plate 52 and the like have openings 51b.
(FIG. 8) Inserted from the inside. The electrode plate 52 is made of a thin metal plate such as zinc having carbon adhering to one surface thereof, the separator 53 is made of paper, and the pellet 54 is made of a mixture of manganese, acetylene black or the like. Then, in the battery cell 50, the separator 53 and the pellet 54 are impregnated with the electrolytic solution, and when the electrode plate 52 and the pellet 54 are connected to an external electric circuit, the electric charge is discharged to the electric circuit.

Next, a conventional method for assembling a battery cell will be described below. In the conventional battery cell assembly method,

Is made of a material having a friction coefficient larger than that of the outer peripheral surface of the metal index table 13, such as rubber,
The guide 22 is provided so as to cover the inner diameter surface of the guide 22 within a predetermined range. As a result, when the holding jig 1 is sandwiched between the index table 13 and the guide 22 and conveyed, the holding jig 1 rotates on its axis in front of the protrusion 22a (details will be described later). Instead of the index table 13, a belt conveyor or the like that moves along a linear movement path is used, and instead of the guide 22, the linear movement path fixed to the linear movement path is fixed.

Next, the insertion mechanism 30 of the assembling apparatus and its operation will be described with reference to FIG. FIG. 4 is an explanatory diagram showing an insertion mechanism and its operation in the battery cell assembling apparatus according to the first embodiment of the present invention. In this embodiment as well, the electrode plate 52 is covered by the insertion mechanism 30 in the same manner as in the conventional example.
Only the step of inserting the inside of the separator 1 will be described, and the separator 53
The description of the step of inserting the pellet 54 and the pellet 54 will be omitted. As shown in FIG. 4A, the insertion mechanism 30 is composed of a metal plunger 31 that moves in the vertical direction in the figure, a suction portion 32 attached to the plunger 31, and a projecting pin 33. In addition, the insertion mechanism 30 is the index mechanism 10.
The electrode plate 52 is inserted into the inside of the covering member 51 at a location indicated by an arrow “D” in FIG. 3, for example. The suction part 32 is connected to an intake mechanism (not shown) and vacuum-sucks a member such as the electrode plate 52. A suction pad 32a made of a flexible elastic material such as rubber is provided at the tip of the suction portion 32. Protruding pin 33
Is connected to an external drive mechanism and is movable in the vertical direction in FIG.

Next, the operation of the insertion mechanism 30 will be described with reference to FIG. First, the insertion mechanism 30 sucks the electrode plate 52 by the suction portion 32, as shown in FIG. At this time, since the pad 32a at the lower end of the adsorption portion 32 is made horizontal, the light electrode plate 52 is in a posture parallel to the opening 51b of the covering member 51, and the electrode plate 52 is arranged on the opening 51b. . The electrode plate 52 is held and conveyed by the holding jig 1 by another index mechanism 10 provided near the index mechanism 10 that conveys the covering member 51.
The electrode plate 52 is positioned on the holding jig 1 so that it has a predetermined orientation. As a result, the opening 51b of the covering member 51 and the electrode plate 52 can be easily aligned with each other. Subsequently, in the insertion mechanism 30, as shown in FIG. 4C, the projecting pin 33 projects to the lower side of the drawing and the electrode plate 52.
By pushing down one end side of the
The posture is inclined with respect to 1b. At this time, the electrode plate 5
Since the pad 32 is deformed according to the inclination of 2, the electrode plate 5
2 does not come off from the suction part 32. Then, as shown in FIG. 4D, the insertion mechanism 30 moves to the lower side of the drawing to cover the electrode plate 52 inside the covering member 51 in a posture in which the electrode plate 52 is inclined with respect to the opening 51b. To insert. In this way, the reason why the electrode plate 52 is inserted in the inclined posture is that the lower end of the electrode plate 52 is first opened by opening the opening 51b.
Since it is inserted in the middle part, not the end part of the
There is no possibility that the lower end of the plate collides with the end of the opening 51b and deforms it to cause insertion difficulty.
This is because there is no possibility that the portion of the upper end of 2 will collide with the other end of the opening 51b to deform it and cause insertion difficulty. Next, as shown in (e) of FIG. 4, the insertion mechanism 30 stops the adsorption of the electrode plate 52 at the adsorption portion 32, and completes the insertion of the electrode plate 52 inside the covering member 51. In this way, the insertion mechanism 30 causes the electrode plate 52 to move to the opening 5
The electrode plate 52 can be easily inserted into the inside of the covering member 51 because the electrode plate 52 is inserted at an angle with respect to 1b. In this device, the projecting pin 33 tilts the electrode plate 52 with respect to the opening 51b by pushing down one end of the electrode plate 52 that is attracted by the deformable attracting portion 32. Can be simplified, and the electrode plate 52 can be tilted at high speed.

As described above, according to the battery cell assembling apparatus and the battery cell assembling method of the present invention, the index cell mechanism allows the constituent members of the battery cell to be circumferentially conveyed, and the battery cell can be assembled during the conveyance. Therefore, the battery cells can be assembled at high speed in a small occupied space.

Further, since the groove 2e is provided in the direction perpendicular to the surface on which the holding jig 1 rotates (the surface of rotation in the direction indicated by the arrow "G" in FIG. 7), the groove 2e fits into the fitting portion 20. When fitted with the pin 20a, the holding jig 1 can be more firmly fixed to the recess 14 of the index table 13 than in the first embodiment. In this embodiment, the cross-shaped groove portion including the groove portion 2a and the groove portion 2e is provided in the base portion 2 and is fitted to the fitting portion 20 and the fitting pin 20a, respectively. Instead of being provided, the rotation of the holding jig 1 may be stopped and fixed to the recess 14 by fitting the groove 2e and the fitting pin 20a.
