Abstract
The invention discloses a kind of power lithium-ion battery liquid injection port clean method, liquid injection port is cleaned using laser before lithium-ion-power cell liquid injection port laser seal, CCD is installed on marking machine to take pictures detecting system, Automatic-searching liquid injection hole simultaneously determines position, automatically going out laser will need the marking of laser welded seal portion faces whole to clean, electrolyte, foreign matter and the surface oxide layer vaporization at high temperature during marking is crystallized, as smoke discharging dust removing system is taken away, to place sealing valve block and carry out laser welding.Advantages of the present invention：Machine instead of manually, and fluid injection discharge surface and surrounding electrolyte crystallization, oxide layer and foreign matter once all remove, and seals not fried fire during laser welding, ensures sealing yields, efficient cost is low；Automatic-searching liquid injection hole simultaneously determines position, and automated cleaning, crystallizing electrolyte, foreign matter and the surface oxide layer vaporization at high temperature during marking, as smoke discharging dust removing system is taken away, will not pollute surrounding environment.
Description
Technical field
The present invention relates to a kind of power lithium-ion battery liquid injection port clean method, belong to technical field of lithium batteries.
Background technology
With the continuous progress of lithium-ion-power cell technology, the lithium ion battery of metal shell increasingly becomes mainstream, gold
Belong to housing battery due to having the advantages that high stability, high security, small and tolerable temperature scope are wide, it is in the market
Occupation rate constantly rises.Lithium battery in the fabrication process, when into battery container inject electrolyte after, due to electrolyte to be maintained
Stability and need to be sealed the liquid injection port of battery container, at present generally using being laser welded seal, this kind of technology
Efficient, sealing effect is good, but needs to clean liquid injection port before sealing, not so the crystallization electrolyte of liquid injection port,
Foreign matter and surface oxide layer, which do not remove, can cause to fry fiery leakage during laser welding, and the clean method used at present is manually with dustless
Cloth or non-dust cloth are wiped, this kind of method not only inefficiency, and electrolyte crystallization and the complete wiped clean of foreign matters, oxygen
Change layer, which can not remove, fries fiery leakage when causing laser welding, and non-dust cloth or dust-free paper can not reuse, and cause cost
Also it is higher.
The content of the invention
The technical problem to be solved in the present invention, is that providing a kind of machine instead of manually, fluid injection discharge surface and surrounding electricity
The crystallization of solution liquid, oxide layer and foreign matter once all remove, and seal not fried fire during laser welding, ensure the power lithium of sealing yields
Ion battery liquid injection port clean method.
The present invention is realized by following proposal：A kind of power lithium-ion battery liquid injection port clean method, in lithium ion power
Liquid injection port is cleaned using laser before battery liquid-filling mouth laser seal, laser liquid injection port surrounding according to laser cleaning rail
One circle of mark movement.
Liquid injection port is cleaned using laser marking machine before lithium-ion-power cell liquid injection port laser seal, laser mark
Quarter the laser that sends of machine in the surrounding of liquid injection port according to one circle of laser index carving cleaning track movement.
It is followed the steps below：
Step 1, on laser marking machine installs CCD and takes pictures detecting system；
Step 2, by CCD take pictures detecting system Automatic-searching liquid injection port and determine laser index carving clean track；
Step 3, the surface whole marking cleaning at laser welded seal position will be needed by going out laser automatically；
Step 4, enters the lower section of laser-beam welding machine after step 3 cleaning by assembly line, and automatic sealing valve block of placing carries out
Laser welding.
In the step 3, crystallization electrolyte, foreign matter and the surface oxide layer vaporization at high temperature during laser index carving, then
Taken away by smoke discharging dust removing system.
In the step 4, sealing valve block automatic positioning is placed on the clean position of laser index carving.
Beneficial effects of the present invention are：Machine instead of manually, fluid injection discharge surface and surrounding electrolyte crystallization, oxide layer and
Foreign matter once all removes, and seals not fried fire during laser welding, ensures sealing yields, efficient cost is low；Automatic-searching is noted
Fluid apertures simultaneously determines position, and going out laser automatically will need the marking of laser welded seal portion faces whole to clean, crystallization electrolyte, different
Thing and the surface oxide layer vaporization at high temperature during marking are taken away with smoke discharging dust removing system, will not pollute surrounding environment.
Embodiment
The present invention is further described below, but the scope of the present invention does not limit to the content.
For clarity, not describing whole features of practical embodiments, in the following description, known function is not described in detail
And structure, because they can make the present invention chaotic due to unnecessary details, it will be understood that opening in any practical embodiments
In hair, it is necessary to a large amount of implementation details are made to realize the specific objective of developer, such as according to related system or related business
Limitation, another embodiment is changed into by one embodiment, additionally, it should think that this development is probably complicated and expends
Time, but it is only to those skilled in the art routine work.
A kind of power lithium-ion battery liquid injection port clean method, uses before lithium-ion-power cell liquid injection port laser seal
Laser cleans liquid injection port, and laser is enclosed in the surrounding of liquid injection port according to laser cleaning track movement one.
Liquid injection port is cleaned using laser marking machine before lithium-ion-power cell liquid injection port laser seal, laser mark
Quarter the laser that sends of machine in the surrounding of liquid injection port according to one circle of laser index carving cleaning track movement.
It is followed the steps below：
Step 1, on laser marking machine installs CCD and takes pictures detecting system；
Step 2, by CCD take pictures detecting system Automatic-searching liquid injection port and determine laser index carving clean track；
Step 3, the surface whole marking cleaning at laser welded seal position will be needed by going out laser automatically；
Step 4, enters the lower section of laser-beam welding machine after step 3 cleaning by assembly line, and automatic sealing valve block of placing carries out
Laser welding.
In the step 3, crystallization electrolyte, foreign matter and the surface oxide layer vaporization at high temperature during laser index carving, then
Taken away by smoke discharging dust removing system.
In the step 4, sealing valve block automatic positioning is placed on the clean position of laser index carving.
Although more detailed elaboration is done to technical scheme and has been enumerated, it will be appreciated that for ability
For field technique personnel, modification is made to above-described embodiment or uses equivalent alternative solution, this is to those skilled in the art
