The invention discloses a full-automatic
voltage internal resistance testing
system which comprises a feeding platform, an advancing and retreating working platform, a turntable mechanism and a discharging conveying belt. A feeding, sorting,
visual positioning and monitoring
robot is used for grabbing the battery cells on the feeding platform, carrying out
visual positioning and detection on the battery cells and placing the battery cells on the advancing and retreating working platform, a side
voltage testing mechanism is used for carrying out side
voltage testing on the battery cells on theadvancing and retreating working platform, and an upper turntable transfer
manipulator is used for transferring the qualified battery cells to the turntable mechanism. A tab shaping mechanism, a
battery cell body
temperature testing mechanism, a code scanning mechanism and a
battery cell voltage
internal resistance testing mechanism which are arranged at each working position of the turntable mechanism are respectively used for the tab shaping, a
battery cell body temperature test, the code scanning and a battery
cell voltage
internal resistance test, and a discharging sorting
robot is used for discharging the battery cells from the turntable mechanism to the discharging conveying belt. According to the test
system, the voltage and internal
resistance test efficiency of the small square battery cells is improved, and the
test data is more stable.
