Description
Technical field
The present invention relates to plate bound edge circle explosion-proof line explosion rupture disks.
Background technique
The appearance of battery is the life of our mankind, amusement and work provide necessary power supply guarantee.With society
The progress of development and human civilization, one-shot battery is due to the pollution to environment, capacity is low, using the time it is short the disadvantages of gradually will be by
The secondary cell for the advantages that superseded instead pollution-free, capacity is big, long service life.Wherein cylinder type lithium battery is held
There are distinctive self structure and performance to be widely used every field, as laptop, mobile power source, electric tool etc.
It is exactly representative therein.
Security combination nut cap is the most important safety guarantee component of cylinder type lithium battery, the structure and life of combination cover cap itself
The manufacturing cost of the direct or indirect performance for affecting lithium battery of production. art and battery producer.But with regard to the lithium of different capabilities electricity
Pond is in the practical application of different field, according to the requirement of itself manufacturing process, the peace using different structure for the property of can choose
Full combination cover cap, to reduce manufacturing cost.
The lithium battery of low capacity can choose the security combination nut cap with simple type, in the case where performance is constant with substitution
Security combination nut cap used in capacity type and power lithium battery reduces manufacturing cost.
In cylinder type lithium battery manufacturing process, the laser welding of positive pole ear is by combination cover cap welding region and tab side
To limitation, it is inconvenient for operation, efficiency reduce, increase the manufacturing cost of battery.
Summary of the invention
In order to solve defect in the prior art, the present invention provides a kind of plate bound edge circle explosion-proof line explosion rupture disk, packet
Include disk-shaped main body portion, and by main part edge extend upward on prolong portion；
The bottom surface of the main part is equipped with positive pole ear laser welding area.
Preferably, positive pole ear laser welding area is circle.
Preferably, the positive pole ear laser welding area heart coaxial with aforementioned body portion.
Preferably, positive pole ear laser welding area is aluminium.
The present invention is making security combination cap and cell positive pole ear laser used in low-capacity batteries for battery producer
The problems of welding, develops that a kind of welding region is big, limit simultaneously and used in other security combination nut caps by tab direction
To explosion rupture disk have the plate bound edge circle explosion-proof line explosion rupture disk of same performance.
The present invention has a characteristic that
1, traditional taper explosion rupture disk and aluminium ring are combined into one by the present invention, can reduce the process in security combination nut cap production.
2, the conical surface of existing taper explosion rupture disk is changed to plane by the present invention, can increase the area of cell positive pole ear laser welding
Domain.
3, this invention simplifies the manufacture technologies of nut cap.
4, present invention reduces the manufacturing costs of battery.

The bottom surface of the main part 11 is equipped with positive pole ear laser welding area 13.
Positive pole ear laser welding area 13 is circle.
The heart coaxial with aforementioned body portion 11 of positive pole ear laser welding area 13.
Positive pole ear laser welding area 13 is aluminium.
Plate bound edge circle explosion-proof line explosion rupture disk of the present invention is selected and " aluminium " of the same material of taper explosion rupture disk, by taper
The outer diameter of explosion rupture disk and the technical requirements (both explosion-proof performances) of explosion-proof line, it is stamping with dedicated equipment.
As shown in figure 4, cylinder type lithium battery can be used plate bound edge circle explosion-proof line explosion rupture disk of the invention, and in Fig. 4,1
It is explosion rupture disk for top cap, 2,3 be sealing ring, and 4 be steel shell, and 5 be battery core.
Traditional taper explosion rupture disk and aluminium ring are combined into one by the present invention, can reduce the work in security combination nut cap production
Sequence.
The conical surface of existing taper explosion rupture disk is changed to plane by the present invention, can increase the area of cell positive pole ear laser welding
Domain.
The explosion-proof chip architecture of plate bound edge circle explosion-proof line of the present invention is simple, is easy to use, and improves cell positive pole ear and swashs
The efficiency of photocoagulation greatly reduces the total manufacturing cost of battery producer.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
