Description

A kind of barrier film arc measurement instrument and its measuring method
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
It is an object of the present invention to:In view of the shortcomings of the prior art, a kind of barrier film arc measurement instrument is provided, reduced Measurement error, improves measurement accuracy.
To achieve these goals, the present invention uses following technical scheme:
A kind of barrier film arc measurement instrument, including casing, pressing plate, pressing plate fixed mechanism and aspiration pump, the casing is by printing opacity The solid space that top plate, bottom plate and side plate are surrounded, the intermediate region of the top plate is set to measurement zone, and the measurement zone is set It is equipped with the horizontal scale for measuring diaphragm length, the vertical scale for measuring diaphragm radian and the suction for adsorbing barrier film Attached hole, the pressing plate is fixed on the initiating terminal of the measurement zone, the aspiration pump and the case by the pressing plate fixed mechanism The inside connection of body.
On the one hand, barrier film is covered on the top plate of casing using pressing plate in the present invention, in the presence of aspiration pump, absorption Hole plays suction-operated to barrier film and flattens barrier film, and because aspiration pump is adjustable, therefore, the tension force suffered by barrier film is Controllable, so as to reduce measurement error, improve measurement accuracy;On the other hand, horizontal scale and vertical scale are arranged on top On plate, it is to avoid because steel ruler cover in membrane surface and caused by barrier film deformation or corrugation, so as to more accurately to barrier film Length and radian are measured.
Improved as one kind of barrier film arc measurement instrument of the present invention, length of the horizontal scale along the top plate Direction is set, and width of the vertical scale along the top plate is set.It is preferred that, the zero graduation line and level of vertical scale Scale is overlapped, and reading is become larger from middle zero graduation to two ends.
Improved as one kind of barrier film arc measurement instrument of the present invention, the horizontal scale is provided with one group, described Vertical scale is provided with multigroup, and the distance between vertical scale is equal described in two adjacent groups.Multigroup vertical scale is to set to cause The radian of barrier film many places can be easily and accurately measured simultaneously.
Improved as one kind of barrier film arc measurement instrument of the present invention, the adsorption hole is arranged in two adjacent groups in column Between the vertical scale.Adsorption hole is uniformly arranged in column so that the absorption affinity suffered by barrier film is more uniform, and tiling effects are more Plus.
As barrier film arc measurement instrument of the present invention one kind improve, the pressing plate fixed mechanism include fixed mount, Plug housing, motion bar and spring, the fixed mount setting have motion bar connecting portion and spring coupling part, and the plug housing is installed on On the pressing plate, one end of the motion bar is inserted in the motion bar connecting portion, and the other end of the motion bar is inserted in institute Plug housing is stated, one end of the spring is connected with the spring coupling part, and the other end of the spring is connected with the plug housing. By plug housing and motion bar pressing plate is fixedly connected with fixed mount, and spring then enables in thickness of the pressing plate according to barrier film Lower movement, does not destroy membrane surface.
Improved as one kind of barrier film arc measurement instrument of the present invention, the fixed mount setting is the Yin of Daoing " " shape.
Improved as one kind of barrier film arc measurement instrument of the present invention, in addition to lighting mechanism, the lighting mechanism Including support, LED lamp tube and power line, the support is fixed on the bottom plate, and the LED lamp tube is set up in the support On, the power line is electrically connected with the LED lamp tube.In use, power line is connected with external power source, LED lamp tube lights, The light that LED lamp tube is sent will transmit through top plate, so that scale is apparent on barrier film, facilitate reading.
