310 temperature feedback of gel that device will test is to control system, and control system controls size of current and conduction time, until heat is multiple
After the completion of conjunction, the first cylinder 5 decline, the second cylinder 15 rises, and it is multiple that one 310 spacing of gel of advance of metal tape 300 carries out heat
Subsequent processing 220 is closed, the heat that tab shaping mechanism continues next gel 310 is compound.
Embodiment two
The embodiment of the present invention two discloses the tab forming method of tab shaping mechanism described in embodiment one, is used for metal tape
300 with the hot compound working procedure of gel 310, include the following steps:
Step S1: the metal tape 300 after overlaying and gel 310 are threaded through between conductive mechanism 150 and pressing mechanism 110 and the
One electrode 8 and the contraposition of second electrode 9 are set in the two sides of gel 310, the position of the corresponding not set gel 310 of metal tape 300
It sets；
The S2: the first cylinder of step 5 acts, and first electrode 8 and second electrode 9 rise and contact metal tape 300；
The S3: the second cylinder of step 15 acts, and the first briquetting 17 and the lower general who has surrendered's metal tape 300 of the second briquetting 18 are pressed on first electrode
8 and second electrode 9 on；
Step S4: opening DC power supply 120, and the metal tape 300 between first electrode 8 and second electrode 9 is made in heating effect of current
Heating up it is compounded in 310 heat of gel on sheet metal rapidly with lower.
Step S5: after the completion of heat is compound, the first cylinder 5 decline, the second cylinder 15 rises, one pole of the advance of metal tape 300
310 spacing of ear glue repeats step S2, step S3 and step S4.
