Description
Technical field
The invention belongs to barrier film detection device technical field, more particularly to a kind of barrier film arc measurement instrument and its measurement side
Method.
Background technology
Lithium ion battery is made up of positive pole, negative pole, barrier film and electrolyte.Barrier film as the big material of lithium ion battery four it
One, account for about the 20% of whole battery cost.In process of production, the basic parameter of barrier film detection includes：Thickness, width, face are close
Degree, radian etc..Wherein, the radian of barrier film directly affects the quality of membrane winding, and then influences the use quality of lithium battery.
At present, the radian method of testing that lithium ion battery separator is used in the industry is usually：First, interception certain length every
Film as sample, by sample be laid in it is smooth, be difficult to produce barrier film on the flat board of Electrostatic Absorption；Secondly, beside barrier film
Steel ruler A is placed, and steel ruler A two ends are fixed；Then, then take another steel ruler B, by itself and the perpendicular shapes of steel ruler B be placed on every
In the middle of the effective length of the place of film radian most serious, usually barrier film measurement；Finally, the barrier film and steel ruler A at steel ruler B are read
Between distance value, as barrier film radian value.
However, existing radian method of testing has the following disadvantages：1）Tested barrier film is typically unfolded using nature or is used hand
Application pulling force is able to extravagance and come, and the tension force suffered by it is uncontrollable, so as to cause measurement error very big；2）Use steel
Chi is directly laminated at tested membrane surface, easily because artificial operation causes barrier film film surface to deform or wrinkle, and then causes to survey
Measure error.
The content of the invention
