Description
Technical field
The present invention relates to plastic-aluminum packaging film, copper foil, aluminium foil bending resistance detection technique field more particularly to a kind of detections
The jig and its detection method of foil bending resistance.
Background technology
With the development of the times, the update of consumer electronics product and the promotion of national new-energy automobile, lithium from
Sub- secondary cell occupies important role in people's lives.To show one's talent in keen competition, lithium battery needs
Develop toward the direction of higher energy density, longer cycle life, more reliable safety.For identical material,
Improve the thickness that energy density is most direct, most common method is thinned material.But it, accordingly can band after material stock thickness is thinned
Carry out other problems, it is as poor such as bending resistance the problems such as, make result that expected performance requirement be not achieved
Plastic-aluminum packaging film is mainly combined by nylon, aluminium foil, PP, is widely used in food, electrical type and national defence tip
The packaging of product.Plastic-aluminum packaging film serves as important role in soft bag lithium ionic cell, it is desirable that it is with preferable deep-draw
Property, electrolyte resistance stability, high barrier property and bending resistance etc..Plastic-aluminum packaging film needs in soft package lithium battery production process
Through overshooting the processes such as shell, top side seal, two envelopes, flanging, packaging bag is made in the plastic-aluminum packaging film of sheet, this just needs aluminum-plastic packaged
Phenomena such as film has good folding resistance, and often the plastic-aluminum packaging film of folding resistance difference will appear chink or breakage, eventually leads to battery
It scraps.The bending resistance of plastic-aluminum packaging film is examined currently without a kind of unification, reliable method, and many producers can not be from
The suitable material of oneself is selected in numerous materials.Because of a kind of new, reliable method of the invention, to assess the bending resistance of foil
Can, it is imperative.
Foil bending resistance is broadly divided into two methods of bending manually and automatic bending at present.The general base bent manually
This step is:Sample is cut into the batten of about 150mm long, 15mm wide, and first estimates the number resistant to bending of the batten, two hands are respectively held
Firmly batten one end, by batten doubling, then along the doubling back and forth of 90 ° of folding line position.Reach estimate bending number when, by batten pair
It light source and checks whether there is broken hole, such as do not occur broken hole, then continue doubling and checked whether broken hole again 1 time, until there is broken hole
Until;If reaching when estimating number, has there is broken hole in batten, then reduces bending number.Experiment defines the bending of just non-broken hole
Number is the value resistant to bending of the material.106248503 A of patent CN《A method of test plastic-aluminum packaging film folding resistance》, say
A kind of method of automatic bending test, substantially testing procedure are stated:One end of the batten cut out is clamped with fixture, in sample
The other end hangs weight, sets certain angle and carries out waving bending, reaches bending place after estimating number against light source inspection
Survey whether broken hole, until plastic-aluminum packaging film just non-broken hole when, the bending number that is carried out both had been the value resistant to bending of the material.
The shortcoming bent manually is poor repeatability, and the number difference resistant to bending for measuring foil is big.Sample when automatic bending
Item exists with fixture to rub, and the batten for hanging weight can extend under external force, and crooked place can change, and measure
As a result there is certain deviation, and cannot achieve automatic detection.The method that the present invention is bent using foil single-point, detected in real time, both
Automatic bending is realized, and realizes automatic inspection, especially whether timing monitoring sample to be tested bends failure.

Further, the shifting bar is connected by movable block with workbench.
A kind of detection method of the jig of detection foil bending resistance, it is characterised in that:Include the following steps:
A, foil to be tested is cut into rectangular foil, it is ensured that the rectangular foil after sanction is intact, smooth, do not crumple;
B, rectangular foil is attached on the cylindrical sides that radius is 5mm-100mm, it will be square around cylindrical sides
Shape foil circumnutates into cylindric, is unclamped after 1min, rectangular foil is allowed to be in a natural flexuosity;
C, a detection vertex is selected on the rectangular foil after circumnutating, and manually to light pressure on the inside of curved surface, while being taken rectangular
The left comer of foil rotates outward with right corner, until left comer is got together with right corner;Then the rear portion of rectangular foil is inhaled with rear
Disk is connected, and left comer is connected with the side sucker on left swing mechanism and right swing mechanism respectively with right corner, to the left by sliding block
Or move right, it drives and moves bar outward or move inward, and then the side on left swing mechanism and right swing mechanism is driven to inhale
Disk is inwardly or outwardly swung, and is bent with square shaped foil, and when ensureing rectangular foil bending, detection vertex position is constant, together
