Abstract
The invention discloses a pressure tester with an intelligent sensing function. The pressure tester comprises a motor, a tester main body and a testing platform, and is characterized by further comprising a measuring head, an enlarger and a PLC (programmable logic controller), wherein the measuring head is controlled by the motor, is used for applying pressure, is connected with the tester main body and is positioned above the testing platform, a force sensor is arranged in the measuring head, acquires force signals in real time and transmits the signals to the enlarger connected with the force sensor, the enlarger feeds back the signals to the PLC, and the PLC is connected with the motor and controls the motor to run or stop according to the fed-back signals. The pressure tester has the advantages that damage moment of a screen can be reliably judged, and the pressure tester can be reliably controlled to stop; pressure on the screen is recorded when the screen is damaged, and pressure resisting times of the screen under certain pressure can be recorded.
Description
Technical field
The present invention relates to a kind of pressure tester, be specifically related to a kind of intelligent sensed pressure tester.
Background technology
The compression resistance that needs its screen of test after notebook, MP3, MP4 etc. accomplish and make; The equipment that adopts is pressure tester; Its ultimate principle is exactly to utilize a gauge head to apply pre-set acting force to screen; Carry out the pressure test of set point number, whether last view screen damages, to confirm the compression resistance of screen.
But often have a problem in the reality test: whether pressure tester can not damage by the perception screen, just repeats simply screen is exerted pressure, in case screen damages, repetition pressure test repeatedly is also just futile.
Summary of the invention
For solving the deficiency of prior art; The objective of the invention is to overcome the defective of prior art; A kind of intelligent sensed pressure tester is provided, can judges reliably whether screen damages, thus pressure size that the damage of record screen is and the withstand voltage number of times under the certain pressure.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
Intelligence sensed pressure tester; Comprise motor, tester main body, test platform; It is characterized in that, also comprise: receive the gauge head that is used to exert pressure, amplifier and the PLC of Electric Machine Control, above-mentioned gauge head is connected with the tester main body and is positioned at above the test platform; Above-mentioned gauge head inside is provided with strength sensor; Above-mentioned strength sensor is gathered the strength signal in real time and signal is transferred to connected amplifier, and above-mentioned amplifier is given PLC with signal feedback, and above-mentioned PLC is connected with motor and controls motor rotation or shutdown according to feedback signal.
Aforesaid intelligent sensed pressure tester is characterized in that, the feedback signal that above-mentioned PLC receives shows that pressure continues to increase, and the control motor keeps running; The feedback signal that above-mentioned PLC receives shows several times pressure and continues to descend, and control motor stall is also write down pressure size and compression number.
Aforesaid intelligent sensed pressure tester is characterized in that, the feedback signal that receives as above-mentioned PLC shows lasting decline of pressure 5-15 time, and control motor stall is also write down pressure size and compression number.
Aforesaid intelligent sensed pressure tester is characterized in that, above-mentioned gauge head is that elastomeric material is processed.
Usefulness of the present invention is: intelligent sensed pressure tester of the present invention, 1, can judge reliably when screen damages and the controlled pressure tester is shut down; Pressure size when 2, the record screen damages, the while can also be noted the withstand voltage number of times of certain pressure sub-screen.
Description of drawings
Fig. 1 is the structural representation of intelligent sensed pressure tester of the present invention;
Fig. 2 is that the motor among Fig. 1 keeps running and the pressure-deformation discharge curve synoptic diagram when shutting down.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done concrete introduction.
Intelligent sensed pressure tester of the present invention; Has identical essential structure with existing pressure tester: comprise motor, tester main body, test platform; Most important difference is that it possesses intelligent perceptional function; Whether screen damages in can the sensed pressure test process, thereby in time stops destructive test, and pressure size when noting screen and damaging and the withstand voltage number of times under the certain pressure.
Referring to Fig. 1, pressure tester of the present invention also comprises: the gauge head that is used to exert pressure, amplifier and the PLC (programmable logic controller (PLC)) that receive Electric Machine Control.Wherein, Gauge head is connected with the tester main body and is positioned at above the test platform; Gauge head inside is provided with strength sensor; Strength sensor is gathered the strength signal in real time and signal is transferred to connected amplifier, and amplifier is given PLC with signal feedback, and PLC is connected with motor and controls motor rotation or shutdown according to feedback signal.
As a kind of preferred, gauge head is that elastomeric material is processed.
Shown in Figure 2 when being 20kg for set pressure, the relation during each gauge head action between pressure and the deflection.Specifically, the feedback signal that receives as PLC shows that pressure continues to increase, and shown in the solid line among Fig. 2, promptly is to represent screen intact, and PLC just controls motor maintenance running so; And in case the feedback signal that receives as PLC shows the lasting decline of several times pressure, shown in dotted line among Fig. 2, promptly be to represent screen damaged, PLC just controls the motor stall and writes down pressure size and compression number so.So just, carry out intelligent perception expediently, thereby judge and the running and the shutdown of control motor through utilizing the difference of intact screen and the pressure-deformation discharge curve of damaged screen.
In the pressure test process; Might occur pressure does not once in a while increase situation about rising with deflection, so, and in order to prevent erroneous judgement; We are through preestablishing this problem of avoiding; As a kind of preferred, the feedback signal that receives as PLC shows lasting decline of pressure 5-15 time, and control motor stall is also write down pressure size and compression number.
More than show and described ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand, and embodiment does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
