Description
Technical field
The present invention relates to one kind stretching detecting system, and in particular to the resistance to tensile strength quality inspection system of diaphragm.
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 diaphragm system as screen protecting film slowly
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 the requirement of surface protection for product compared with Asia 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 for being 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 it
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 completely instead of South Korea's film, and nearly 2 years Japanese and South Korea diaphragm producers are
Through going into operation in continent or having set up co-partnership company.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 for packaging, coating line investment compared with
Height, so real diaphragm manufacturer is simultaneously few, can make original film well just less.So most of factory is only
Secondary, three process segments of diaphragm are rested on, the lower level stage is belonged in whole diaphragm industrial chain.With regard to Area distribution
For, be mainly distributed on Shenzhen, Foshan, the 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 fashion pursuit of people of the high-end diaphragm to meet 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, certainty of measurement is low, complex operation, and cannot 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
Few link, existing protection film stretching detection is general using using remeasurement is matched somebody with somebody, certainty of measurement is low, complex operation by hand, and
Stress strain curve cannot continuously be recorded, it is therefore intended that provide diaphragm outgoing 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
Measurement, certainty of measurement is low, complex operation, and cannot continuously record the problem of stress strain curve.
The present invention is achieved through the following technical solutions：
The resistance to tensile strength quality inspection system of diaphragm, including processor and connection tensiometer on a processor, database and PWM
Controller, the PWM controller is also connected with buncher；
Processor：Send control signals to PWM controller；The pulling force parameter of tensiometer is read, pulling force parameter is stored in number
According to storehouse
Database：The pulling force parameter that receiving processor sends is stored；
Tensiometer：The pulling force that detection diaphragm bears, generates pulling force parameter；
PWM controller：The control signal of receiving processor, control buncher work；
Buncher：Control signal according to PWM controller is operated.After start-up operation, processor is transmitted a signal to
PWM controller, PWM controller controls buncher work according to the control signal of processor, meanwhile, processor reads tensiometer
The pulling force parameter for detecting, pulling force parameter is stored in database in order, and processor keeps to tensiometer in the course of the work
Reading, it is ensured that the parameter linearity of reading is high, while carrying out extra operation without operating personnel.
Clock chip is also associated with the processor.Delay function is provided, true use environment is simulated, controller according to
Clock signal control PWM controller is alternately opened and closed.
Position sensor is also associated with the processor.Position sensor can be with the deformation of real-time detection diaphragm, just
In generation stress strain curve.
The buncher uses stepper motor.Stepper motor is that electric impulse signal is changed into angular displacement or displacement of the lines
Opened loop control motor, is the main executive component in modern digital program control system, using extremely wide.In the feelings of non-overload
Under condition, the rotating speed of motor, the position for stopping are solely dependent upon the frequency and umber of pulse of pulse signal, without the shadow by load change
Ring, when step actuator receives a pulse signal, it with regard to Driving Stepping Motor by the direction of setting rotate one it is fixed
Angle, accuracy is high, and controllability is strong.
Communication module is also associated with the processor.The data for being easy to processor to detect outwardly send in real time.
The present invention compared with prior art, has the following advantages and advantages：
1st, the resistance to tensile strength quality inspection system of diaphragm of the present invention, high degree of automation, the tensile property of automatic detection diaphragm；
2nd, the resistance to tensile strength quality inspection system of diaphragm of the present invention, with single time delay module, simulates true use environment.
