Abstract
The invention relates to the technical field of welding, in particular to a lithium ion battery laser welding system. The lithium ion battery laser welding system comprises a laser device, a light guiding system, a worktable, a battery assembly fixing tool clamp, a control system and a cooling system. A laser is guided to a machining head composed of a focused light tool or a uniform light tool through the laser device of the light guiding system. The worktable is used for fixing the battery assembly fixing tool clamp. A two-shaft motion module, a CCD monitoring module, a rack, an electronic control system and a software system are arranged on the worktable. The welding quality is further improved through the specific cooling airflow direction, and in the process of realizing cooling, the situation that the normal flowing-out path and strength of protective gas of laser welding is not influenced by an ejected air flow is guaranteed.
Description
Technical field
The present invention relates to welding technology field, more particularly to a kind of lithium ion battery laser welding system.
Background technology
Existing lithium ion is basic at present due to the requirement to environment, it is impossible to cooled down using liquid in welding process
Directly blown against laser welding compressing fixture using compressed air and cooled down, or when just work a period of time waits one section
Between carry out natural cooling, because welding position needs inert gas and is protected in laser beam welding, the side directly blown
Formula, can affect laser beam welding inert protective gas；The latter has a strong impact on production efficiency.
The content of the invention
For defect present in prior art or deficiency, the technical problem to be solved is：A kind of energy is provided
Enough realize the lithium ion battery laser welding system of automatic cooling function.
To achieve these goals, the technical scheme that the present invention takes is a kind of lithium ion battery laser welding system of offer
System, including laser instrument, light-conducting system, workbench, battery component fixing tool fixture, control system, cooling system, the leaded light
System by laser by laser instrument guide to by focusing light or even smooth optical system into processing head, the workbench is used for self-contained battery
Component fixing tool fixture, is provided with two axle motion modules, CCD monitoring modules, frame, electric-control system, soft on the workbench
Part system.
As a further improvement on the present invention, the two axles motion module is combined by two servo platforms and constituted, and each is watched
Take platform drives ball screw motion, linear guides to be oriented to using high-precision motor, and servo platform drives plumb joint to be welded.
As a further improvement on the present invention, the CCD monitoring modules include that two CCD are coaxial with two collimation focusing heads
Install.
As a further improvement on the present invention, the frame by square steel panel beating by being welded.
As a further improvement on the present invention, the battery component fixing tool fixture include clamp mechanism, inflatable body,
Targeting part, the clamp mechanism adopts cylinder clamping, is positioned using location-plate, and closed type clamp lamps structure prevents welding slag from splashing
To product surface；The inflatable body blows protective gas using side-blown mode is installed additional, and the targeting part makes workpiece along gathering sill
In being put into fixture, clamping efficiency is improved.
As a further improvement on the present invention, the cooling system adopts closed-loop path cooling system, including liquid pump, heat to hand over
Parallel operation and container.
The invention has the beneficial effects as follows：The present invention by specific cooling air-flow direction, so as to further improve welding matter
Amount, during protecting realization cooling of correcting a wrongly written character or a misspelt word, the air-flow of ejection does not interfere with the normal outflow path of the protective gas of laser welding
And intensity.
Specific embodiment
With reference to explanation and specific embodiment, the present invention is further described.
The present invention provides a kind of lithium ion battery laser welding system, including laser instrument, light-conducting system, workbench, battery
Component fixing tool fixture, control system, cooling system, the light-conducting system laser is guided to by focusing light by laser instrument or
Even smooth optical system into processing head, the workbench be used for securing battery cell packs fixing tool fixture, on the workbench arrange
There are two axle motion modules, CCD monitoring modules, frame, electric-control system, software systems.
The two axles motion module is combined by two servo platforms and constituted, and each servo platform is driven using high-precision motor
