3) top cover and explosion rupture disk component after welding are transferred into turnover mechanism, and implement to overturn by turnover mechanism, become explosion-proof
Piece is upper, and state of the top cover under, is subsequently delivered at the plate washer feed mechanism of hole；
4) plate washer feed mechanism in hole works, and hole plate washer is stacked to explosion rupture disk, then component is integrally sent on orifice plate
Expect at mechanism；
5) orifice plate feed mechanism works, and orifice plate is overlayed on the plate washer of hole, then component is integrally sent to second laser welding
It sets seat in the plane；
6) orifice plate and explosion rupture disk are welded and fixed for second laser bonding machine work, so that top cover, explosion rupture disk, orifice plate and hole plate washer
Four component fixations are integral, then are sequentially delivered to cap assembly height detection sensing device and cap assembly resistance detection sensing
Device carries out height and resistance detection, and cap assembly height detection sensing device and cap assembly resistance detection pass if unqualified
Induction device can issue warning alert worker and choose rejected product, and non-defective unit is then finally sent to sealing ring feed mechanism；
7) sealing ring feed mechanism works, and sealing ring is placed into above orifice plate, then five components are integrally sent to pressing machine
Structure is pressed, to form cylindrical lithium ion cell cap；
8) assembled cylindrical lithium ion cell cap continues to be sent to taking-up station with cap assembly ring shaped transportation mechanism, by people
Work takes out transfer.
Need to illustrate that the first laser bonding machine in the present invention, second laser bonding machine and laminating mechanism are existing skill
Art is well known to those skilled in the art, and the present invention is no longer described in detail.
The invention has the advantages that
The present invention can be automatically performed the assembling production of nut cap, not only high-efficient, and terminal with compact integral structure, take up little area, make simultaneously
