Description
Technical field
The present invention relates to electric automobile field, particularly relate to a kind of device for BUSBAR solder joint tension test detection.
Background technology
China is in the energy conversion period of vehicle at present, and new energy vehicle increases the most day by day, in each big business
In, the safety of new energy vehicle, increasingly paid close attention to by people, and weldering between BUSBAR and battery core in the module of vehicle
The reliability of point, determines the safety of vehicle, if there is solder joint rosin joint, battery may be caused to package fire.Therefore, in welding
After, need butt welding point to carry out tension test detection, to judge whether welding quality meets the requirements, at present, carry out stretching detection examination
Test after typically the battery core being welded with BUSBAR being put in tension test platform, push down battery core with a block pressur plate, then with bolt, pressing plate is solid
Being scheduled on testing stand, this mode cannot ensure the accuracy of the position of battery core, uniform during also cannot ensureing tension test
Stress, also cannot press from both sides the center of positive BUSBAR when of holder BUSBAR, so testing result error is very big, very
To sometimes losing measurement meaning；On the other hand, the most simply push down a part for battery core due to pressing plate, so detecting
When to will also result in result inaccurate, also can cause the possibility directly battery core shell broken.
Summary of the invention
