Description
Technical field
The present invention relates to technical field of automatic control, particularly relate to a kind of power battery pack laser automation welding control system side
Method.
Background technology
Application laser welding is the most universal to the technique of soft package lithium battery bond pads at present, is essentially all by each
The nickel strap of two lugs of soft-package battery and the substrate of copper nickel plating carry out Laser Welding, and have different qualities according to different polarity
Metal Material Welding.At present, for profile and the size of lithium battery, GB does not has strict regulation, therefore along with lithium battery
Application more and more extensive, the soft package lithium battery specification kind of each producer is different, and counting of welding differs, the most sharp
Light automatic welding production line is only to one or two kind of soft-package battery bond pads, to its technology application, marketing, cost price all
There is no small limitation.
Owing to lithium battery group laser welding process needs, existing welding manner many employings artificial loading board unit welds
Connect, single product automatic welding production line carrys out completing technology requirement.
At least there is the deficiency of following aspect in prior art:
1, tradition single product soft package lithium battery group laser automatic welding production line uses high performance PLC to carry out overall control
System, although frock is simple, is well positioned to meet polytechnic requirement, seriality, the typing of data and analysis, but can only expire
The technique of the set of cells welding of the single model of foot, if the debugging of laser welding production line can be caused bigger by switching model
Impact, and owing to the debugging time can affect production, complicated structure, expensive price, harsh technical maintenance requirement, make this
Plant automatic welding production line and general welding user is brought too much burden, process and real so cannot well be used for applying
During border produces；
2, the welding of artificial loading board unit can be inputted by DXF file due to the track of welding, switches the type of battery
Number fairly simple, but stability is the poorest, and whole technological process compares too many levels so that it is work efficiency is extremely low, both cannot be large quantities of
Amount carry out welding production, again cannot continuously to set of cells other Function detection, install and measure, therefore it is complete to be welded into power
Cannot ensure, the set of cells of whole technical process cannot be carried out analysis and the typing of data, this can requirement to operator
Extremely harsh.
Summary of the invention
In view of this, the present invention proposes the power battery pack laser automatic welding that a kind of compatibility is good, welding precision is high
Control method.
