Abstract
The utility model provides a cylinder type lithium ion battery annotates liquid sleeve pipe, includes the sleeve pipe body, the port is the liquid outlet under the sleeve pipe body, and the integrative fixedly connected with filling funnel in this internal middle part of sleeve pipe, liquid mouth downside fixedly connected with drainage post is annotated for annotating the liquid mouth to the port under the filling funnel. It between liquid mouth and the liquid outlet is the 40% -70% of the whole height of sleeve pipe body apart from H1 to annotate. The radius R2 who annotates the liquid mouth is liquid outlet internal diameter R1's 10% -40%. The high H2 of drainage post is 5 -20mm. The utility model discloses be equipped with the filling funnel at the middle part of sleeve pipe body, annotate liquid mouth below and be equipped with the drainage post, can be under the condition that does not influence normal notes liquid, effectual reduction lithium ion battery is in follow -up loss of taking out brokenly vacuum in -process electrolyte, the utilization ratio, the reduction loss that improve electrolyte.
Description
Technical field
The utility model relates to a kind of lithium battery manufacture equipment, particularly relates to a kind of injecting cylindrical lithium-ion battery sleeve pipe.
Background technology
At present, lithium ion battery owing to having, energy density is high, memory-less effect, have extended cycle life, the excellent properties such as environmental protection and obtain very large development and application.But for cylindrical lithium ion battery, because the full-automatic fluid injection equipment price of production and application is high, some companies still utilize HighPower pump to carry out manual fluid injection, then adopt the mode vacuumized to be pressed onto in battery core by electrolyte by vacuum drying chamber.But in the process of carrying out vacuum breaker, understand some electrolyte and dissipated by fluid injection cover, cause the waste that some are unnecessary.
Summary of the invention
The purpose of this utility model be to provide a kind of can effectively reduce cylindrical lithium ion battery taking out, vacuum breaker time electrolyte loss amount, improve the injecting cylindrical lithium-ion battery sleeve pipe of electrolyte utilance.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of injecting cylindrical lithium-ion battery sleeve pipe, comprise sleeve body, sleeve body lower port is liquid outlet, it is characterized in that, integral middle in sleeve body is fixedly connected with filling funnel, and filling funnel lower port is liquid injection port, is fixedly connected with drainage post on the downside of liquid injection port.
According to described injecting cylindrical lithium-ion battery sleeve pipe, it is characterized in that, the distance H1 between described liquid injection port and liquid outlet is the 40%-70% of described sleeve body whole height.
According to described injecting cylindrical lithium-ion battery sleeve pipe, it is characterized in that, the radius R 2 of described liquid injection port is the 10%-40% of described liquid outlet internal diameter R1.
According to described injecting cylindrical lithium-ion battery sleeve pipe, it is characterized in that, the height H 2 of described drainage post is 5-20mm.
The utility model is provided with filling funnel at the middle part of sleeve body, drainage post is provided with below liquid injection port, can when not affecting normal fluid injection, the effective lithium ion battery that reduces, in follow-up loss of taking out electrolyte in vacuum breaker process, improves the utilance of electrolyte, reduces the wastage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan structure schematic diagram of Fig. 1.
In accompanying drawing:
1, sleeve body; 2, drainage post; 3, liquid outlet; 4, liquid injection port; 5, filling funnel.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
A kind of injecting cylindrical lithium-ion battery sleeve pipe, as depicted in figs. 1 and 2, comprises sleeve body 1, sleeve body 1 lower port is liquid outlet 3, integral middle in sleeve body 1 is fixedly connected with filling funnel 5, and filling funnel 5 lower port is liquid injection port 4, is fixedly connected with drainage post 2 on the downside of liquid injection port 4.Distance H1 between described liquid injection port 4 and liquid outlet 3 is the 40%-70% of described sleeve body 1 whole height.The radius R 2 of described liquid injection port 4 is 10%-40% of described liquid outlet 3 internal diameter R1.The height H 2 of described drainage post 2 is 5-20mm.
In the utility model, the manufacture material of sleeve body is polyethylene (PE), polypropylene (PP), poly terephthalic acid class plastics (PET) or polytetrafluoroethylene (PTFE).
The drainage post of the utility model by arranging on the basis of former lithium ion battery liquid injection sleeve pipe below filling funnel and liquid injection port, both the normal fluid injection of cylindrical lithium ion battery can have been facilitated, can effectively reduce again because of battery core loss amount of electrolyte during vacuum breaker after fluid injection, Loss reducing, reduces production cost.
