<p>The present invention relates to a cylindrical cell welding jig comprising: a pair of jig cases which have multiple semi-cylindrical cell supporting groove parts formed in the center of an inner surface in a lateral direction, an adhering part protruding from both sides of the inner surface, and multiple magnets installed on each front surface of the semi-cylindrical cell supporting groove part, each front surface of the adhering part, and upper and lower end surfaces; and a pair of cover cases which have multiple cylindrical cell seating groove parts formed on central front and rear sides of a lower surface or central front and rear sides of an upper surface to correspond to each semi-cylindrical cell supporting groove part of the jig cases in a lateral direction, a through hole formed on the center of each cylindrical cell seated groove part, and multiple magnets installed on an outer edge of a lower surface or an outer edge of an upper surface. The cylindrical cell welding jig can stably support multiple cylindrical cells at an accurate welding point, prevent various safety accidents by accurately and precisely welding the cylindrical cells, and quickly finishing the welding work, thereby remarkably reducing productivity and costs.</p> |
