Abstract
The utility model discloses an intelligent sensing pressure tester. The intelligent sensing pressure tester comprises a motor, a tester main body and a test platform. The intelligent sensing pressure tester is characterized by further comprising a test head which is controlled by the motor and is used for applying pressure, an amplifier and a programmable logic controller (PLC), wherein the test head is connected with the tester main body and is positioned above the test platform, a force sensor is arranged in the test head, acquires force signals in real time and transmits the signals to the amplifier which is connected with the force sensor, the amplifier feeds the signals back to the PLC, and the PLC is connected with the motor and controls the motor to rotate or stop according to the feedback signals. The intelligent sensing pressure tester has the beneficial effects that the intelligent sensing pressure tester can reliably judge when a screen is damaged and controls the pressure tester to stop; and the pressure when the screen is damaged is recorded, and the pressure-resistant times of the screen at certain pressure can also be recorded.
Description
Technical field
The utility model relates to a kind of pressure tester, is specifically related to a kind of pressure tester of Intellisense.
Background technology
Notebook, MP3, MP4 etc. finish the compression resistance that needs to test its screen after the manufacturing, 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 determine 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.
The utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to overcome the defective of prior art, a kind of pressure tester of Intellisense is provided, can judges reliably whether screen damages, thus the 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 utility model adopts following technical scheme:
The pressure tester of Intellisense; comprise motor, tester main body, test platform; it is characterized in that; also comprise: gauge head, amplifier and the PLC exert pressure of being used for that is subjected to 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 Real-time Collection strength signal also is transferred to connected amplifier with signal; to PLC, above-mentioned PLC is connected with motor and controls motor rotation or shutdown according to feedback signal above-mentioned amplifier with signal feedback.
The pressure tester of aforesaid Intellisense 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 continuous decrease, and the control motor stalling also records pressure size and compression number.
The pressure tester of aforesaid Intellisense is characterized in that, the feedback signal that receives as above-mentioned PLC shows the pressure continuous decrease 5-15 time, and the control motor stalling also records pressure size and compression number.
The pressure tester of aforesaid Intellisense is characterized in that, above-mentioned gauge head is that elastomeric material is made.
Usefulness of the present utility model is: the pressure tester of Intellisense of the present utility model, 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 recorded the withstand voltage number of times of certain pressure sub-screen.
Description of drawings
Fig. 1 is the structural representation of the pressure tester of Intellisense of the present utility model;
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 the drawings and specific embodiments the utility model is done concrete introduction.
The pressure tester of Intellisense of the present utility model, has identical essential structure with existing pressure tester: comprise motor, tester main body, test platform, most important difference is that it possesses the Intellisense function, whether screen damages in can the sensed pressure test process, thereby in time stop destructive test, and the pressure size when recording screen and damaging and the withstand voltage number of times under the certain pressure.
Referring to Fig. 1, pressure tester of the present utility model also comprises: gauge head, amplifier and the PLC(programmable logic controller (PLC) exert pressure of being used for that is subjected to 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 Real-time Collection strength signal also is transferred to connected amplifier with signal; to PLC, PLC is connected with motor and controls motor rotation or shutdown according to feedback signal amplifier with signal feedback.
As a kind of preferred, gauge head is that elastomeric material is made.
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, namely is that represent screen intact, and PLC just controls motor and keeps turning round so; And in case the feedback signal that receives as PLC shows several times pressure continuous decrease, as shown in phantom in Figure 2, namely be to represent breakage of screen, PLC just controls motor stalling and records pressure size and compression number so.So just by utilizing the difference of intact screen and the pressure-deformation discharge curve of damaged screen, carry out expediently Intellisense, thereby judge and running and the shutdown of control motor.
In the pressure test process, pressure might occur once in a while and not increase situation about rising with deflection, so, in order to prevent erroneous judgement, we are by preseting to avoid this problem, as a kind of preferred, the feedback signal that receives as PLC shows the pressure continuous decrease 5-15 time, and the control motor stalling also records pressure size and compression number.
More than show and described ultimate principle of the present utility model, principal character and advantage.The technician of the industry should understand, and embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in the protection domain of the present utility model.
