Formula is begun to warm up to the pole on battery 8；
B. trimming, pipette tips continue to move down, and magnetic conductive rod 21 is on the battery 8 that is synchronously heated and softened
Pole, which synchronizes, to be pressed to after it contacts with the lug plate of binding post so that pole is complete higher than the part above lug plate
Flatten, that is, complete the leveling of pole end；
C. welding sequence, after completing the step b, after magnetic conductive rod 21 contacts with the lug plate of binding post, now, pressure
The stress of sensor 32 changes, and pressure signal is fed back to master controller, drive mechanism 6 drives and moves to initial bit in pipette tips
During putting, magnetic conductive rod 21 departs from pole, completes pole surface melting welding, that is, completes the welding of the binding post of battery 8, according to
Secondary reciprocation cycle.
When the stress of pressure sensor 32 changes, increase electromagnetic induction coil input power, transition piece 312 and pressure
Before force snesor 32 departs from, caused vortex, to 350~400 DEG C, makes pole surface and is overlaid on to connect to pole end heat
Lead on line piece is fused into lead liquid and completes welding, and now the height between magnetic conductive rod 21 and pole is 0.5~3mm.
When the present invention carries out melting welding to pole so that the leading section of magnetic conductive rod 21 departs from pole does not contact melting welding, prevents from melting
The lead liquid of change is adhered on magnetic conductive rod 21, is on the one hand avoided on magnetic conductive rod 21 because adhesion lead liquid causes the too high damage of temperature；It is another
Aspect ensures welding quality, avoids solder side from uneven situation occur.
In the present embodiment, the temporal summation that weld assembly 2 departs from beginning to its completion reset with pole in the step c is
0.3~1s.
Further, the step b pipette tips continue in folding process, and weld assembly 2 passes through first with control unit 31
The elastic reaction of elastic component 313 leans all the time with corresponding pole and pressure sensor 32 respectively.
The setting of first elastic component 313 in the present embodiment, on the one hand realize that two-way linkage acts on, made using its elastic reaction
Obtain pipette tips to move down, magnetic conductive rod 21 pushes pole while end synchronous drive transition piece 312 moves up and pressure sensor 32 thereafter
Contact control, synchronism is good, and control accuracy is high；On the other hand for the highly different battery 8 of pole melting welding, its trimming
During play surplus adjustment effect, expand welding gun of the present invention to the welds types scope of battery 8.
Moreover, to move down stroke holding synchronous for pole heating and softening amount in the step b on battery 8 and pipette tips, and should
During pole end region temperature be heated to 300~340 DEG C so that pole realize softening, it is pushed beneficial to magnetic conductive rod 21
Shaping.
In the present embodiment, weld assembly 2 in the step a and step b pole is carried out precompressed feeding and shaping when
Between summation be 1~2s.
The foregoing description of the disclosed embodiments, those skilled in the art are made not depart from the spirit and scope of the present invention
In the case of, various changes or equivalence replacement can be carried out to these features and embodiment.In addition, under the teachings of the present invention,
These features and embodiment can be modified with adapt to particular situation and material without departing from the present invention spirit and
Scope.Therefore, the present invention is not limited to the particular embodiment disclosed, and falls with claims hereof scope
Interior embodiment belongs to protection scope of the present invention.
