Description
Technical field
Detection means is stretched the present invention relates to one kind, and in particular to diaphragm tensile strength detection means.
Background technology
Diaphragm can be divided into protective film for digital product according to purposes, and protection film for automobile, family expenses diaphragm, food fresh keeping is protected
Cuticula etc..As the digital products such as mobile phone are in the popularization of China, a kind of the of screen protecting film that turn into of diaphragm slowly unites
Claim, and its function in screen protecting film field is also multifarious, earliest high definition is scratch resistant, to GLAUKE now, 180 degree and
OK8 functional form diaphragms it is in one's favour.AR material of the material from earliest PP materials to popular, centre experienced more than 5 years
Development, being received by vast mobile phone colony slowly.Originally main production concentrate on Japan, the industry prosperity such as the U.S. and Europe
Country, because American-European industrialization development is more early, therefore is put into compared with Asia the requirement of the surface protection for product earlier,
To reduce by factory up in the intermediate links in market, for product in transport, carry, during storage, or even display,
The loss of the surface tear run into.The brand then unrivalled whole world on the diaphragm of rubber-type glue in Europe, and rubber-type glue
The diaphragm of water is also due to its characteristic, is up to the present still the post-processings such as stainless steel plate, aluminium sheet, or even part plastic parts
In complicated industry.And Japan starts to walk relatively early in nontoxic PVC materials and PET materials and AR material developments, technology is more first
Enter, so, mobile phone screen protection film Japan, development in South Korean is also more rapid.Japan and Korea S mainly produce middle and high end safeguard film for cellular phone, and to its
State's outer vent PVC, PET and AR material.China's Mainland as Mobile Phone Consumption big country, the production and selling of protecting film of mobile phone screen compared with
It is many, through development in a few years, the diaphragm of higher-end can be produced, though the diaphragm away from Japan still has certain difference
Away from, but for now, there is the trend for replacing South Korea's film completely, and nearly 2 years Japanese and South Korea diaphragm producers are
Through going into operation or having set up co-partnership company in continent.For the production of China mobile pad pasting, its mainly as some adhesive tape factories,
Electronic material factory, the non-main business of diaphragm factory are managed.The producer for specializing in diaphragm production is less, because diaphragm original film
Production and coating process it is complex, many technical elements need to be broken through, and a blown film packaged, coating line investment compared with
Height, so really diaphragm manufacturer and few, can make former film well just less.So most of factory is only
Secondary, three process segments of diaphragm are rested on, belong to the lower level stage in whole diaphragm industrial chain.With regard to Area distribution
For, be mainly distributed on the Shenzhen, Foshan, Dongguan in Guangdong, and Zhejiang, Shanghai and Jiangsu some areas.But with existing
The prevalence of modern touch-screen mobile phone and the concern to 3G mobile, diaphragm market is also paid close attention to by more businessmans.Many producers
Start to produce high-end diaphragm to meet the fashion pursuit of people of young man.
The tensile strength detection of diaphragm is the essential link of diaphragm factory testing, existing protection film stretching inspection
Survey general using using remeasurement is matched somebody with somebody, measurement accuracy is low, complex operation, and can not continuously record stress strain curve by hand.
The content of the invention
The technical problems to be solved by the invention are that the tensile strength detection of diaphragm is that diaphragm factory testing must can not
Few link, existing protection film stretching detection is general using using remeasurement is matched somebody with somebody, measurement accuracy is low, complex operation by hand, and
Stress strain curve can not continuously be recorded, it is therefore intended that provide diaphragm tensile strength detection means, the stretching for solving diaphragm is strong
Degree detection is the essential link of diaphragm factory testing, and existing general use of protection film stretching detection uses counterweight by hand
The problem of measuring, measurement accuracy is low, complex operation, and continuously can not record stress strain curve.
The present invention is achieved through the following technical solutions：
Diaphragm tensile strength detection means, including processor, two it is parallel just to etc. long stent, tensiometer, servo
Motor and the capstan winch being connected on servomotor, the tensiometer and servomotor are connected on a processor, in two branch
Also be vertically installed between frame two just to clamping device, one of clamping device is fixed on one end of support, another
Clamping device is connected by slide rail with two supports, and the servomotor and capstan winch are arranged on support and are fitted without clamping device
One end, capstan winch is connected by drawstring and tensiometer with the clamping device of activity.Diaphragm is fixed between two clamping devices,
Servomotor, the working condition of processor record servomotor and the pulling force situation of tensiometer are started by processor.
The displacement transducer being connected with processor is additionally provided with the support, institute's displacement sensors pass through a connection
Bar is connected with the clamping device of activity.The deformation of detection diaphragm in real time, is easy to draw stress strain curve.
Institute's displacement sensors, which are set, to be located at close to one end of fixed clamping device.Displacement transducer sets and influenced whether
The moving range of movable clamping device, closer to fixed clamping device, on smaller using influenceing.
The connecting rod is perpendicular to clamping device.Connecting rod is easy to intuitively measurement activity clamping dress perpendicular to clamping device
The displacement put.
Spring is additionally provided between the capstan winch and tensiometer.Buffer gear, when servomotor is acted, makes clamping device
Mobile distance is less than the length for the drawstring that capstan winch is withdrawn, and further improves precision, simultaneously, it is to avoid the relatively low diaphragm of ductility
Directly broken.
The present invention compared with prior art, has the following advantages and advantages：
1st, diaphragm tensile strength detection means of the present invention, using servomotor, measure data precision is higher, and data are continuous
Property is strong；
2nd, diaphragm tensile strength detection means of the present invention, with spring buffer structure, the relatively low guarantor of measurable ductility
Cuticula.
