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 couplable with a battery storage retaining a plurality of flat-rechargeable batteries arranged in parallel, and a plurality of chuck units continuously joined with the first guide and resiliently arranged in parallel, wherein the chuck units each have a second guide resiliently positioning each of the chuck units with a predetermined number of 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 couplable with a battery storage retaining a plurality of flat-rechargeable batteries arranged in parallel; and

a plurality of chuck units continuously joined with the first guide and resiliently arranged in parallel, wherein

the chuck units each have a second guide resiliently positioning each of the chuck units with a predetermined number of 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.
