Separator tension control device for stacking secondary batteries

A separator tension control device for stacking a separator of a secondary battery, the device comprising:

• a separator stacking member (110) having:
• a separator stacking unit (112) installed on an upper surface of a table (111) such that negative and positive plates of a secondary battery are alternately stacked by a separator (132);
• and a fixing plate (114) which allows a separator supply member (130) and a separator dancer member (150) to be installed thereon;
• the separator supply member (130) installed on one side of the separator stacking unit (112) so as to supply the separator (132) to the separator stacking unit (112);
• and
• the separator dancer member (150) installed on an upper side of the separator stacking member (110) such that the separator (132) supplied from the separator supply member (130) is supplied with constant tension,
• wherein the separator dancer member (150) comprises:
• a dancer unit (151) installed on the fixing plate (114) such that the dancer unit (151) is rotated by a predetermined limited angle such that the separator (132) moved from the separator supply member (130) maintains constant tension;
• a tension elastic unit (161) installed on one side of the dancer unit (151) such that the dancer unit (151) is rotated clockwise and counterclockwise by the predetermined limited angle by elasticity of the tension elastic unit (161) such that the tension of the separator (132) is maintained;
• and
• a dancer tension control unit (171) installed on one side of the tension elastic unit (161) such that the elasticity of the tension elastic unit (161) is controlled.

• and
• a tension spring (200) installed on one side of the dancer tension elastic unit (190) such that the elasticity of the dancer tension elastic unit (190) is controlled.
