Start to drive battery core rotation；Battery core rotation rotation is divided into two stages, first stage：In this stage, only the first optical fiber 73
Work, motor 61 drives battery core to be rotated by 360 °, if the first optical fiber 73 senses the number of times of lug for 2 times (in this stage, motor
Just sense that lug is not considered 1 sensing number of times when not rotating), then it is judged to that two lugs are misaligned, this battery core will not be welded
And be delivered to subsequent work stations and subsequently excluded as defective products；If the first optical fiber 73 senses that the number of times of lug is 1 time, judge
For two lugs overlap, battery core carries out the rotation of second stage；Second stage：In this stage, the first optical fiber 73 and the second light
Fine 74 work simultaneously, and the motor 61 on motor lug alignment mechanism 6 continues to drive battery core to continue to rotate, when the first optical fiber 73 senses
During to cell polar ear, motor 61 continues rotation and (just senses that lug is considered in this stage, when motor 61 is not rotated to have sensed
Lug), when the first optical fiber 73 is just sensed less than lug, motor 61 stops operating, the cell polar ear for now overlapping rotate to
Minimum point, if now the second optical fiber 74 senses lug, is judged to that this cell polar ear registration is bad, and this battery core will not be welded
Subsequent work stations are connect and are delivered to subsequently to be excluded as defective products；If now the second optical fiber 74 is also sensed less than lug, it is now
Positioning on circumferencial direction is carried out to the positive pole ear in battery core, has then been judged to that this cell polar ear registration is good, will be delivered to
Subsequent work stations are welded
