Abstract
The utility model discloses a kind of cylindrical lithium ion battery steel shell end sockets, by increasing a flexible precompressed mandrel in end socket, the head of precompressed mandrel contacts first and pushes down nut cap when sealing, make to fit closely at nut cap and steel shell slot position, then end socket pushes again carries out steel shell mouth crimping, guarantees the leakproofness of sealing and the molding of steel shell mouth.
Description
Technical field
The present invention relates to one kind may be mounted above cylindrical lithium ion battery sealing machine, effectively solve cylindrical lithium from
Because decrement deficiency leads to the end socket for sealing poor air-tightness at sub- battery steel shell nut cap and steel shell slot position.
Background technique
Sealing is the key that cylindrical lithium ion battery manufacturing process, and key technical index is sealing air-tightness, sealing
The problem of not leading to battery drain solution liquid sternly, troubles always lithium battery manufacturing.Before sealing, need nut cap being pressed into steel shell
It is interior, if not lasting forces after nut cap indentation, it may appear that rebound, nut cap is not fitted closely with steel shell slot position when sealing
Together, cause air-tightness after sealing bad, electrolyte oozes out and corrodes nut cap, seriously affects the quality and safety of product.
Summary of the invention
In order to overcome the disadvantages mentioned above of the prior art, the present invention provides one kind may be mounted at cylindrical lithium ion battery
Above sealing machine, effectively solve at the nut cap of cylindrical lithium ion battery steel shell and steel shell slot position because decrement deficiency causes to seal gas
The end socket of close property difference.
The technical scheme is that
A kind of cylindrical lithium ion battery steel shell end socket, including precompressed mandrel (1) and end socket (4) two parts.Precompressed mandrel
(1) spring (3) that outer surface cover one matches with its diameter, precompressed mandrel (1) are installed to the inside of end socket (4) and with outside 2
Hexagonal (hexagon)nut (2) is fixed on the top of end socket (4), by adjusting the adjustable precompressed mandrel in position of 2 outer-hexagonal nuts (2)
(1) expose the length of end socket (4), to change the precompressed dynamics of spring (3).
When battery (6) reach sealing position, end socket (4) declines with precompressed mandrel (1) is synchronous, the head of precompressed mandrel (1)
Radical first contacts nut cap (5), and nut cap (5) is persistently pushed down until end socket (4) completes crimping encapsulation, then end socket to steel shell mouth
(4) rise, battery (6) enters subsequent processing, completes sealing movement.
This cylindrical lithium ion battery steel shell end socket has strong applicability, easy for installation, small in size, cost of manufacture is low etc.
Advantage can increase substantially product quality and safety.
Detailed description of the invention
Fig. 1 is sectional view of the invention, Fig. 2 is the sides figure such as of the invention;
Wherein, 1- precompressed mandrel, 2- outer-hexagonal nut, 3- spring, 4- end socket, 5- nut cap, 6- battery.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and specific embodiments.
The present invention includes precompressed mandrel (1) and end socket (4) two parts.The outer surface cover of precompressed mandrel (1) one and its diameter phase
Matched spring (3), precompressed mandrel (1) are installed to the inside of end socket (4) and are fixed on end socket (4) with 2 outer-hexagonal nuts (2)
Top, the length of end socket (4) is exposed by adjusting the adjustable precompressed mandrel (1) in position of 2 outer-hexagonal nuts (2), with
Change the precompressed dynamics of spring (3).
The cylindrical lithium ion battery steel shell end socket is threadedly secured on sealing machine by outside, when battery (6) reach
When sealing position, end socket (4) declines with precompressed mandrel (1) is synchronous, and the head of precompressed mandrel contacts nut cap (5) first, and will lid
Cap (5) is persistently pushed down until end socket (4) completes crimping encapsulation to steel shell mouth, and then end socket (4) rises, and battery (6) enters next
Process completes sealing movement.When precompression is spent it is big or too small when, can be by adjusting 2 of precompressed mandrel (1) tail portion outer six
The position of angle nut (2) changes dynamics.
This cylindrical lithium ion battery steel shell end socket, which can effectively solve, to be bonded not tight at nut cap and steel shell slot position, cause to seal
Leakproofness is poor after mouthful, leaks the problem of electrolyte, has and does not change existing equipment route and program, easy for installation, small in size, processing
The advantages that low manufacture cost, quick adjustment, product quality and security performance can be increased substantially.
Claims (2)
1. a kind of cylindrical lithium ion battery steel shell end socket, including precompressed mandrel (1), outer-hexagonal nut (2), spring (3) and envelope
Head (4), it is characterised in that: the spring (3) that the outer surface cover of precompressed mandrel (1) one matches with its diameter, precompressed mandrel (1) installation
To end socket (4) inside and be fixed on 2 outer-hexagonal nuts (2) tops of end socket (4), by adjusting 2 outer-hexagonal nuts
(2) the adjustable precompressed mandrel (1) in position exposes the length of end socket (4), to change the precompressed dynamics of spring (3).
2. cylindrical lithium ion battery steel shell end socket according to claim 1, it is characterised in that: end socket (4) passes through outside
Be threadedly secured on sealing machine.
