Description
Technical field
This utility model belongs to technical field of lithium ion, particularly relates to a kind of isolating membrane testing flatness device.
Background technology
Lithium ion battery is owing to having higher mass energy density and volume energy density, higher running voltage, relatively
Wide use temperature, length in service life, environmentally friendly etc., be widely used mobile phone, notebook computer and
On various electric automobiles, even Aero-Space, wind and solar energy energy storage device.
Lithium ion battery obtains wide variety of while, there is also certain potential safety hazard.Up to the present, existing many
The accident such as mobile phone and notebook battery explosions of rising is reported in media, and this allows people that the security performance of lithium ion battery is created matter
Doubt.And lithium ion battery isolating membrane is to ensure that the pith of security performance of battery, especially under some specific conditions, such as height
Temperature baking, acupuncture, overcharge or foreign body extruding etc. is easy that barrier film causes certain damage.Barrier film once shrinks, melts, aoxidizes,
Puncture the internal short-circuit that will cause battery, cause battery that security incidents such as generating heat, smolder, be the most on fire from explosion occurs.
In view of this, whether a kind of isolating membrane of necessary offer test device meets mark with the quality of detection and isolation film
Standard, thus ensure the security performance of battery.
Utility model content
The purpose of this utility model is: for the deficiencies in the prior art, and provides a kind of isolating membrane testing flatness dress
Put, to detect whether isolating membrane occurs subsiding, it is ensured that isolating membrane quality conformance with standard, thus ensure to use the battery of this isolating membrane
Security performance.
To achieve these goals, this utility model is by the following technical solutions:
Isolating membrane testing flatness device, including testboard, fixed support, support roller, datum line and balancing weight, described solid
Fixed rack is fixed on described testboard, and described support roller is fixed by described fixed support, and described datum line hangs on described
Supporting on roller, described balancing weight is arranged at the two ends of described datum line.
As a kind of improvement of isolating membrane testing flatness device described in the utility model, being shaped as of described testboard
Rectangle.
As a kind of improvement of isolating membrane testing flatness device described in the utility model, described support roller is set to two
Root, two described support rollers are smooth surface round roller.Supporting roller is smooth surface round roller, can guarantee that isolating membrane to be measured will not be subject to
To damaging, do not affect the quality of isolating membrane.
As a kind of improvement of isolating membrane testing flatness device described in the utility model, the half of two described support rollers
Footpath size is identical.Support roller is isometrical is present to ensure that datum line and isolating membrane to be measured keep in the horizontal plane.
As a kind of improvement of isolating membrane testing flatness device described in the utility model, described support roller includes supporting
Roller body and support shaft, described support shaft passes from the center of described support roller body, and the two ends of described support shaft are fixed respectively
On described fixed support.
As a kind of improvement of isolating membrane testing flatness device described in the utility model, the suspension side of described datum line
To vertical with the placement direction of described support roller.
As a kind of improvement of isolating membrane testing flatness device described in the utility model, described balancing weight is set to band
There is the cirque structure of opening.Balancing weight is respectively arranged at datum line and the two ends of barrier film to be measured.Balancing weight make datum line and
Isolating membrane to be measured is straightened by the effect of tension force, it is simple to test.
The beneficial effects of the utility model are: this utility model provides a kind of isolating membrane testing flatness device, including
Testboard, fixed support, support roller, datum line and balancing weight, fixed support is fixed on testboard, supports roller by fixing
Frame is fixed, and datum line hangs on support roller, and balancing weight is arranged at the two ends of datum line.This utility model is sentenced by datum line
Whether disconnected isolating membrane exists subsides, it is judged that isolating membrane quality whether conformance with standard, thus ensure to use the battery of this isolating membrane
Security performance.

Detailed description of the invention
Below in conjunction with detailed description of the invention and Figure of description, this utility model is described in further detail, but this
The embodiment of utility model is not limited to this.
Embodiment
As shown in Figure 1 and 2, isolating membrane testing flatness device, including testboard 1, fixed support 2, support roller 3, datum line
4 and balancing weight 5, fixed support 2 is fixed on testboard 1, supports roller 3 and is fixed by fixed support 2, and datum line 4 hangs on
On support roller 3, balancing weight 5 is arranged at the two ends of datum line 4；Testboard 1 be shaped as rectangle, the material of testboard 1 is marble.
Supporting roller 3 and be set to two, two support roller 3 and are smooth surface round roller, two radius size phases supporting roller 3
With；Supporting roller 3 to include supporting roller body 31 and support shaft 32, support shaft 32 passes from the center supporting roller body 31, support shaft
The two ends of 32 are separately fixed on fixed support 2.The suspension direction of datum line 4 is vertical with the placement direction supporting roller 3.Datum line
4 can be arranged as required to be one or two.Balancing weight 5 is set to the cirque structure with opening.
Operating process of the present utility model is: be first fixed on testboard 1 by fixed support 2, then is fixed on by support roller 3
