Description
Technical field
The utility model belongs to field of lithium more particularly to a kind of cylinder type lithium battery gluing technology.
Background technique
The structure of existing cylinder type lithium battery be positive/negative be all after pole piece head soldering polar ear, pole piece coiling, just/
Negative electrode lug is drawn from the centre of core and tail portion, and cathode point back welding is carried out after core winding into shell, and then slot rolling welding cap cap is most again
After carry out the sealing of whole lid.
And existing battery core slot rolling steel shell notch is not process by processing, battery core notch edges after sealing three times produce
It gives birth to deformation and shell wall is thinning, when finished product battery core is by external force collision, battery slot rolling notch is easy to happen leakage, to influence electricity
Pond appearance and electrical property.
Utility model content
The purpose of this utility model is to provide a kind of cylinder type lithium battery gluing technologies, it is intended to solve the skill of the prior art
The leakage of art scheme battery core slot rolling notch.
The utility model is realized in this way a kind of cylindricality lithium battery convenient for sealing, it is characterised in that: the cylindricality lithium
Battery includes cylinder open at one end and carries out and cover cap tube in the cartridge openings；
The cartridge openings edge is equipped at least two protrusion fixed rings being parallel to each other from top to bottom；
The cap tube inner wall is equipped with reinforcing ring, is equipped between the reinforcing ring and the cap tube edge equipped with surface
Hole for injecting glue；
The cap tube covers when on the cylinder, and the reinforcing ring of the cap tube inner wall and the cartridge openings edge are nearest
Protrusion fixed ring is in contact, drum surface between the corresponding two protrusion fixed rings being parallel to each other of the hole for injecting glue.
Further, irregular protrusion is equipped on the cylinder body outer wall between two adjacent protrusions fixed rings.
Further, annular notch, the protrusion fixed ring locally embedding annular notch are equipped in the reinforcement ring surface
In.
Compared with prior art, beneficial effect is the utility model:
1, it by the way that the glue fixed area of few two protrusion fixed rings being parallel to each other is arranged, enter glue will not exposed
Inner barrel, while there is preferable airtight effect, avoid battery core from leaking.
2, glue is injected by hole for injecting glue, makes it using pressure (injecting glue by hole for injecting glue using vacuum press)
It is evenly distributed on drum surface.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
In picture 1-4, a kind of cylindricality lithium battery convenient for sealing includes that cylinder 1 open at one end and carrying out is covered in the cylinder 1
The cap tube 2 of opening, cylinder 1；
1 open edge of cylinder is equipped with two protrusion fixed rings 3 being parallel to each other from top to bottom；
2 inner wall of cap tube is equipped with reinforcing ring 4, and surface is equipped between 2 edge of the reinforcing ring 4 and the cap tube and is equipped with note
Glue hole 5；
Cap tube 2 covers when on the cylinder 1, and the reinforcing ring 4 and the nearest protrusion of 1 open edge of cylinder of 2 inner wall of cap tube are solid
Determine ring 3 to be in contact, 1 surface of cylinder between the corresponding two protrusion fixed rings being parallel to each other of hole for injecting glue 5, when cap tube 2 is covered in cylinder
When on body 1, and its compression is made by external force, glue is injected by hole for injecting glue 5 by two protrusions by vacuum pressure pump later
Region between fixed ring 3 (when using pressure injecting glue, can make cap tube 2 and cylinder 1 occur Light deformation, cylinder 1 is open outer receipts
Contract and the expansion of cap tube 2), (injecting glue amount is controlled by the control injecting glue time) after glue fills, stops injecting glue, so the glue solidifies
Afterwards (while the glue solidifies, cylinder 1 be open it is micro- expansion substantially restore, cap tube 2 it is micro- contraction substantially restore, can be more preferable
The connection realized between cylinder 1 and cap tube 2), that is, realize the sealing of cap tube 2 Yu cylinder 1.
Irregular protrusion is equipped on 1 outer wall of cylinder between two adjacent protrusions fixed rings 3.
Annular notch 6 is equipped on 4 surface of reinforcing ring, in 3 locally embedding annular notch 6 of protrusion fixed ring, works as reinforcement
When ring 4 connects with 3 surface of protrusion fixed ring, a sealing structure is formed such as in 3 locally embedding annular notch 6 of protrusion fixed ring
In Fig. 5, (be equivalent to and be formed about a sealing structure close to the opening of cylinder 1, the opening of cylinder 1 is separated with glue) is prevented
Glue enters in cylinder 1 along 2 inner wall of cap tube or 1 outer wall of cylinder (because glue is to be injected by vacuum pressed pump by hole for injecting glue 5
, glue has stronger kinetic energy, and sealing structure is under external force, can effectively prevent glue along 1 outer wall of cylinder or
2 inner wall of cap tube enters inside cylinder 1).
When assembling, first battery core will be placed in cylinder 1(cylinder 1) it is fixed, and keep its opening up, then cap tube 2 is covered
When on cylinder 1, the reinforcing ring 4 on 2 inner wall of cap tube leaves the nearest protrusion fixed ring 3 of mouth with 1 outer surface of cylinder and is in contact, and
It rises in 3 locally embedding annular notch 6 of fixed ring, and makes 1 surface of cylinder between 5 alignment protrusion fixed ring of hole for injecting glue, later will
Cylinder 1 and cap tube 2 are fixed, are injecting glue by hole for injecting glue 5 by vacuum pressure pump, are controlling injecting glue amount by the time,
Stop injecting glue after reaching the time, after injecting glue solidification, realizes connection.
The foregoing is merely the preferred embodiments of this practical new shape, are not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
