Description

Simulate the diaphragm detecting system of true use environment

Technical field

It the utility model is related to a kind of stretching detecting system, and in particular to simulate the diaphragm detection system of true use environment System.

Background technology

Diaphragm can be divided into protective film for digital product, protection film for automobile, family expenses diaphragm, food fresh keeping guarantor according to purposes Cuticula etc..As the digital products such as mobile phone are in the popularization of China, a kind of system for turning into screen protecting film of diaphragm slowly Claim, and its function in screen protecting film field is also multifarious, and 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 concentrates on Japan, the industry prosperity such as the U.S. and Europe Country, because American-European industrialization development is more early, therefore the requirement of the surface protection for product is put into compared with Asia earlier, To reduce by factory until in the intermediate links in market, transporting, carrying for product, 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 stainless steel plate, aluminium sheet, or even the post-processing such as part plastic parts In complicated industry.And Japan starts to walk relatively early in nontoxic PVC material and PET materials and AR material developments, technology is more first Enter, so, mobile phone screen protection film is Japanese, and 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 more, through development in a few years, the diaphragm of higher-end can be produced, though still there is certain difference away from Japanese diaphragm Away from, but for now, there is the trend for replacing South Korea's film completely, and the diaphragm producer of nearly 2 years Japan and South Korea is 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, The non-main business of electronic material factory, diaphragm factory is managed.It is less to specialize in the producer of diaphragm production, 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 good former film with regard to less.So most of factory is only Secondary, the process segment three times of diaphragm are rested on, belongs to the lower level stage in whole diaphragm industrial chain.With regard to Area distribution For, it is mainly distributed on the Shenzhen, Foshan, Dongguan in Guangdong, and some areas in Zhejiang, Shanghai and Jiangsu.But with existing The prevalence of modern touch-screen mobile phone and the concern to 3G mobile, diaphragm market are 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 typically using using remeasurement is matched somebody with somebody, measurement accuracy is low, complex operation, and can not continuously record stress strain curve by hand.

Utility model content

Technical problem to be solved in the utility model is that the tensile strength detection of diaphragm is that diaphragm factory testing must Indispensable link, typically using using remeasurement is matched somebody with somebody, measurement accuracy is low by hand, operation is multiple for existing protection film stretching detection It is miscellaneous, and continuously stress strain curve can not be recorded, and it is an object of the present invention to provide diaphragm outgoing detection means, solves the drawing of diaphragm It is the essential link of diaphragm factory testing to stretch intensity detection, and existing protection film stretching detection is typically used using manual With remeasurement, measurement accuracy is low, complex operation, and the problem of can not continuously record stress strain curve.

The utility model is achieved through the following technical solutions：

Simulate the diaphragm detecting system of true use environment, including processor and connection tensiometer on a processor, Database and PWM controller, the PWM controller are 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 reception processing device is sent is stored；

Tensiometer：The pulling force that detection diaphragm is born, generates pulling force parameter；

PWM controller：The control signal of reception processing device, control buncher work；

Buncher：It is operated according to the control signal of PWM controller.After start-up operation, processor transmits a signal to PWM controller, PWM controller control buncher to work according to the control signal of processor, meanwhile, processor reads tensiometer The pulling force parameter detected, pulling force parameter is stored in database in order, and processor is kept to tensiometer in the course of the work Reading, it is ensured that the parameter linearity of reading is high, while extra operation is carried out without operating personnel.

Clock chip is also associated with the processor.Delay function is provided, simulates true use environment, controller according to Clock signal control PWM controller alternately opens and closes.

Position sensor is also associated with the processor.Position sensor can detect the deformation of diaphragm in real time, 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, and application is extremely wide.In the feelings of non-overload Under condition, the rotating speed of motor, the position stopped being 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.It is easy to processor outwardly to send the data detected in real time.

The utility model compared with prior art, has the following advantages and advantages：

1st, the utility model simulates the diaphragm detecting system of true use environment, and automaticity is high, and automatic detection is protected The tensile property of cuticula；

2nd, the utility model simulates the diaphragm detecting system of true use environment, has single time delay module, simulates True use environment.
