Description
Technical field
One kind detection force snesor, belongs to art of pressure sensors, relates generally to a kind of mobile phone screen detection power monitoring and passes
Sensor.
Background technology
With the fast development of the application of smart mobile phone, to the service life requirement for the touch-screen applied on smart mobile phone
It is more and more stricter.The conventional test methodologies of touch-screen service life are using the force measuring machine for being mounted with one point sensing device, pass through survey
The several points of a touch-sensitive screen contact are tried, the tactile speed of point of test pen is adjusted and what force value size carried out test touch screen uses the longevity
Life.However, existing dynamometry technology carries out touch-screen forces testing by then passing through test pen, list can only be once carried out during test
Point test, one piece of touch-screen usually require five points of progress and tested, a middle point, the point of corner four, and a point test is completed
After could carry out remaining several forces testing.Waste time and energy, and comprehensive test of whole touch screen zone can not be carried out, test
Efficiency is low, and precision is poor.Test pen service life is short, it is necessary to often change.Cost is high.
The content of the invention
In order to solve the above problems, the invention discloses a kind of mobile phone screen to detect power monitoring sensor, and testing efficiency is high,
Service life is grown, and precision is high.
The object of the present invention is achieved like this：
A kind of mobile phone screen detects power monitoring sensor, including elastomer, and the elastomer includes fixed part, strain regions and answered
Power groove, loading section and stress groove are arranged on the upper surface of fixed part, and stress groove includes two length direction stress grooves and two
Individual width stress groove, length stress groove and width stress groove is end to end substantially encloses rectangular, length direction stress groove
It is strain regions with width stress groove junction.
The elastomer is flat structure, thickness 6.5mm.
The elastomer includes loading section, and loading section is placed in the both sides that width stress groove encloses region, institute
That states fixed part is surrounded by four first installation screwed holes, and the strain regions are arranged on elastomer length dimension direction, often
At side each two, width does not design strain regions, using flexural loading deformation pattern, so as to form resistance-type strain gauge transducer
Basic structure.
The strain regions include the direct stress position and negative stress position of lower both sides disposed thereon respectively, eight foil gauges point
Direct stress position and the negative stress opening position of four strain regions are not attached to, by two direct stress positions of diagonally connecting into a favour
Stone electric bridge bridge, diagonally connected the other three Wheatstone bridge bridge by identical method, so as to form a complete favour this
Energization bridge.The characteristics of electric bridge is the uneven loading error for counteracting test force, and no matter stress center of gravity is inclined to during so as to reduce loading
The influence that either party brings to test accuracy.
Because touch screen size is generally bigger, when on-load pressure is tested, when test force directly being loaded on into test surfaces,
Due to being plane to plane contact, there is certain requirement to the flatness of contact plane, usual flatness is higher than 0.03mm, compared with
High flatness means the machining cost of costliness, in order to reduce machining cost and it is double do not influence measuring accuracy, it is described plus
Carry part and be provided with boss, the boss is fixed on loading section by the second installation screwed hole, eliminates client when mounted
Need to use 4 pads at loading hole.And only need to ensure the planarity requirements of boss face in machining, greatly reduce
Machining cost, the boss size are 10mm*12mm.
The present invention compared with prior art, has the advantages that structure of the present invention is quick and easy for installation, and traditional
The test mode of one point sensing device is compared, and machine screen detection power monitoring sensor disclosed by the invention is directly installed on touch-screen mould
Group surface, when applying pressure to sensor, whole each region of touch screen surface has been applied in same power, testing efficiency simultaneously
Height, service life length, precision are high, it is possible to achieve the test of different size touch screens, production efficiency is improved, it is easy to spread.
