Automatic pressure jig device for bringing electrode lead into close contact with busbar, and battery module manufacturing system comprising same

Abstract

Discussed is an automatic pressing jig apparatus to couple a bus bar and a lead assembly of a battery module to each other. The automatic pressing jig apparatus can include a first presser and a second presser having a first pressing rod and a second pressing rod, respectively, and at least one contactor connected to both the first presser and the second presser and configured to receive a pressing force from the first presser and the second presser to secure the bus bar to the lead assembly.

What is claimed is: 
     
         1 . An automatic pressing jig apparatus to couple a bus bar and a lead assembly of a battery module to each other, the automatic pressing jig apparatus comprising:
 a first presser and a second presser having a first pressing rod and a second pressing rod, respectively; and   at least one contactor connected to both the first presser and the second presser and configured to receive a pressing force from the first presser and the second presser to secure the bus bar to the lead assembly.   
     
     
         2 . The automatic pressing jig apparatus of  claim 1 , wherein the at least one contactor includes a lead pressing frame having a surface to press the end of the lead assembly at least at one location and to expose another location of the end of the lead assembly. 
     
     
         3 . The automatic pressing jig apparatus of  claim 2 , wherein the lead pressing frame includes at least one horizontal bar that contacts the end of the lead assembly at the one location, and at least one vertical wall that exposes the another location of the end of the lead assembly. 
     
     
         4 . The automatic pressing jig apparatus of  claim 1 , wherein the at least one contactor presses on the bus bar and the end of the lead assembly from intersecting directions. 
     
     
         5 . The automatic pressing jig apparatus of  claim 4 , wherein the at least one contactor includes a lead pressing frame having a surface to press the end of the lead assembly from a first direction and a pressing portion that press on the bus bar from a second direction that intersects the first direction. 
     
     
         6 . The automatic pressing jig apparatus of  claim 1 , wherein the at least one contactor includes a first contacting frame and a second contacting frame coupled by a hinge,
 wherein the first contacting frame includes a first pressing portion and a first distance adjusting portion, and the second contacting frame includes a second pressing portion and a second distance adjusting portion, and   wherein the first pressing portion and the second pressing portion is configured to press on the bus bar from opposite directions.   
     
     
         7 . The automatic pressing jig apparatus of  claim 6 , wherein first pressing portion and the second pressing portion have a same length based on the hinge, and
 wherein the first distance adjusting portion and the second adjusting portion have different lengths based on the hinge.   
     
     
         8 . The automatic pressing jig apparatus of  claim 7 , wherein the first distance adjusting portion is connected to the first presser, and the second distance adjusting portion is connected to the second presser. 
     
     
         9 . The automatic pressing jig apparatus of  claim 8 , further comprising a first pressing rod to connect the first presser and the first distance adjusting portion and a second pressing rod to connect the second presser and the second distance adjusting portion,
 wherein the first pressing rod and the second pressing rod are arranged parallel to each other.   
     
     
         10 . The automatic pressing jig apparatus of  claim 9 , wherein the at least one contactor is provided in plural, and
 wherein among the first distance adjusting portion and the second distance adjusting portion, the first pressing rod is connected to only the first distance adjusting portion and the second pressing rod is connected to only the second distance adjusting portion.   
     
     
         11 . The automatic pressing jig apparatus of  claim 1 , wherein the at least one contactor is configured to simultaneously press the bus bar and an end of the lead assembly so that the lead assembly is not bent against the bus bar. 
     
     
         12 . The automatic pressing jig apparatus of  claim 1 , further comprising a support frame having an opening hole to enable access to the bus bar and the lead assembly and a distance adjuster connected to the support frame and configured to ascend or descend the support frame to move the at least one contactor away from or close to the battery module,
 wherein the first presser and the second presser connected to the support frame at opposite sides thereof.
