Battery assembling apparatus and battery assembly manufacturing method

A method of manufacturing battery assemblies by assembling batteries and frames for accommodating the batteries, the method involving use of a first rotary table and a second rotary table and a second rotary table arranged to face each other at points on respective outer circumferences, the method comprising:

• rotating the first rotary table and the second rotary table in forward directions relative to each other and aligned to face each other at a point in a same planar direction such that the points on respective outer circumferences face each other and rotate in forward directions relative to each other,
• holding a battery with a battery holding part provided on the outer circumference of the first rotary table at a position different from a facing position between the first and second rotary tables,
• holding a frame with a frame holding part provided on the outer circumference of the second rotary table at a position different from the facing position,
• rotating the first and second rotary tables with a rotation speed ratio and in a phase relationship such that the battery holding part and the frame holding part face each other every time at the facing position;
• and
• taking out an assembly of the battery and the frame assembled together from the facing position.
