Abstract

The present invention relates to a chuck mechanism of a charge/discharge testing device for flat-rechargeable batteries and has a proposition to provide a chuck mechanism that makes it possible to lighten conventionally needed troublesome works, that is, for example, works of storing and fixing a large number of flat-rechargeable batteries in a container, and that is capable of surely chucking the flat-rechargeable batteries (electrodes). The chuck mechanism includes a first guide engageable with a battery pressing member of a battery storage which moves according to a battery storage width of a plurality of flat-rechargeable batteries stored in parallel in the battery storage, a plurality of chuck units arranged in parallel by being resiliently and continuously joined and having the first guide on one end side, and a second guide mounted on each of the chuck units, wherein a chuck width of all of the chuck units resiliently arranged in parallel is adjusted according to the battery storage width of the flat-rechargeable batteries by an engagement of the first guide and the battery pressing member, and the second guide positions each of the chuck units being adjusted according to the battery storage width with corresponding flat-rechargeable batteries in the battery storage.

Claims

1. A chuck mechanism of a charge/discharge testing device for flat-rechargeable batteries comprising:

a first guide engageable with a battery pressing member of a battery storage which moves according to a battery storage width of a plurality of flat-rechargeable batteries stored in parallel in the battery storage; and

a plurality of chuck units arranged in parallel by being resiliently and continuously joined and having the first guide on one end side, and

a second guide mounted on each of the chuck units, wherein

a chuck width of all of the chuck units resiliently arranged in parallel is adjusted according to the battery storage width of the flat-rechargeable batteries by an engagement of the first guide and the battery pressing member, and

the second guide positions each of the chuck units being adjusted according to the battery storage width with corresponding flat-rechargeable batteries in the battery storage.

2. The chuck mechanism of the charge/discharge testing device for flat-rechargeable batteries according to claim 1, wherein:

the second guide is made up of a pair of two positioning pins fastening a positioner that is formed in the battery storage corresponding to each of the chuck units; and

each pair of the positioning pins becomes shorter in order from both ends toward a center of the plurality of chuck units arranged in parallel.

3. The chuck mechanism of the charge/discharge testing device for flat-rechargeable batteries according to claim 2, wherein:

the chuck units include

a roller-retaining member which is movable in a front and rear direction of a support base when a driver mounted on the support base is driven and in which a plurality of divided roller-retaining members are movably arranged in parallel via a shaft extending in a left and right direction of the support base, the divided roller-retaining members arranging in parallel a plurality of pairs of rollers vertically on each front surface of the divided roller-retaining members, and

a chuck-retaining member in which a plurality of divided chuck-retaining members each making one unit with each of the divided roller-retaining members are resiliently and movably arranged in parallel via the shaft extending in the left and right direction of the support base;

the divided chuck-retaining members each have a plurality of chuck members each made up of a pair of two strip-formed metal plates inserted through a gap between each of the pairs of rollers, with front end sides of the metal plates fanning out in a V shape in a plane view and with rear end sides of the metal plates coupled with electric wires of the charge/discharge testing device; and

the second guide is provided in each of the divided chuck-retaining members.

4. The chuck mechanism of the charge/discharge testing device for flat-rechargeable batteries according to claim 3, wherein

an oxide film exfoliating/fastening member having a large number of projections on a fastening surface of the oxide film exfoliating/fastening member is fixed on front ends of a pair of two chuck members.

5. The chuck mechanism of the charge/discharge testing device for flat-rechargeable batteries according to claim 4, wherein

the oxide film exfoliating/fastening member has a guide inclining inward from the front end sides of the chuck members toward the fastening surface.

6. The chuck mechanism of the charge/discharge testing device for flat-rechargeable batteries according to claim 4, wherein

slits are formed in a front and rear direction in the front ends of the chuck members, and the oxide film exfoliating/fastening member is fixed on each front end of the chuck members demarcated by the slits.

7. The chuck mechanism of the charge/discharge testing device for flat-rechargeable batteries according to claim 1, wherein:

the chuck units include

a roller-retaining member which is movable in a front and rear direction of a support base when a driver mounted on the support base is driven and in which a plurality of divided roller-retaining members are movably arranged in parallel via a shaft extending in a left and right direction of the support base, the divided roller-retaining members arranging in parallel a plurality of pairs of rollers vertically on each front surface of the divided roller-retaining members, and

a chuck-retaining member in which a plurality of divided chuck-retaining members each making one unit with each of the divided roller-retaining members are resiliently and movably arranged in parallel via the shaft extending in the left and right direction of the support base;

the divided chuck-retaining members each have a plurality of chuck members each made up of a pair of two strip-formed metal plates inserted through a gap between each of the pairs of rollers, with front end sides of the metal plates fanning out in a V shape in a plane view and with rear end sides of the metal plates coupled with electric wires of the charge/discharge testing device; and

the second guide is provided in each of the divided chuck-retaining members.
