Description
Technical field
The present invention relates to a kind of pressure tester, and in particular to a kind of pressure tester of Intellisense.
Background technology
Need to test the compression resistance of its screen after the completion such as notebook, MP3, MP4 manufacture, the equipment used is pressure test
Instrument, its general principle are exactly to apply pre-set active force to screen using a gauge head, set the pressure of number
Test, whether last view screen damages, to determine the compression resistance of screen.
But often had a problem that in reality test：Pressure tester can not perceive whether screen has damaged, only
It is to repeat to apply pressure to screen simply, once if screen has damaged, multiple repetition pressure test also simply futile effort.
The content of the invention
To solve the deficiencies in the prior art, the defects of it is an object of the invention to overcome prior art, there is provided a kind of intelligence
The pressure tester of perception, it can reliably judge whether screen has damaged, so as to record the pressure size that screen damage is
With the pressure-resistant number under certain pressure.
In order to realize above-mentioned target, the present invention adopts the following technical scheme that：The pressure tester of Intellisense, including electricity
Machine, tester main body, test platform, it is characterised in that also include：It is used to apply stressed gauge head, amplification by motor control
Device and PLC, above-mentioned gauge head are connected with tester main body and are located above test platform, and strength is provided with inside above-mentioned gauge head and is sensed
Device, above-mentioned strength sensor gather effort signal and transmit a signal to connected amplifier in real time, and above-mentioned amplifier will
Signal feeds back to PLC, and above-mentioned PLC is operated or shut down with motor connection and according to feedback signal controlled motor.
The pressure tester of foregoing Intellisense, it is characterised in that the feedback signal that above-mentioned PLC is received shows pressure
If continuing to increase, controlled motor keeps operating；The feedback signal that above-mentioned PLC is received shows pressure continuous decrease several times
If, controlled motor stalls and records pressure size and compression number.
The pressure tester of foregoing Intellisense, it is characterised in that when the feedback signal that above-mentioned PLC is received is shown
If 5-15 pressure continuous decrease, controlled motor stalls and records pressure size and compression number.
The pressure tester of foregoing Intellisense, it is characterised in that above-mentioned gauge head is made of elastomeric material.
The present invention is advantageous in that：The pressure tester of the Intellisense of the present invention, 1, can reliably judge to shield
When curtain is damaged and control pressure tester is shut down；2nd, pressure size during screen damage is recorded, while one can also be recorded
The pressure-resistant number of constant-pressure sub-screen.
Brief description of the drawings
Fig. 1 is the structural representation of the pressure tester of the Intellisense of the present invention；Fig. 2 is that the motor in Fig. 1 keeps fortune
Pressure-deformation amount curve synoptic diagram when turning and shutting down.
Embodiment
Make specific introduce to the present invention below in conjunction with the drawings and specific embodiments.
The pressure tester of the Intellisense of the present invention, has identical essential structure with existing pressure tester：Bag
Motor, tester main body, test platform are included, most important difference is that it possesses Intellisense function, being capable of sensed pressure survey
Whether screen has damaged during examination, and so as to stopping destructive testing in time, and pressure when recording screen damage is big
Pressure-resistant number under small and certain pressure.
Referring to Fig. 1, pressure tester of the invention also includes：It is used to apply stressed gauge head, amplification by motor control
Device and PLC（Programmable logic controller (PLC)）.Wherein, gauge head is connected with tester main body and is located above test platform, in gauge head
Portion is provided with strength sensor, and strength sensor gathers effort signal and transmit a signal to connected amplifier, puts in real time
Signal is fed back to PLC by big device, and PLC is operated or shut down with motor connection and according to feedback signal controlled motor.
As a preferred embodiment, gauge head is made up of elastomeric material.
Shown in Fig. 2 to set pressure as 20kg when, the relation during action of each gauge head between pressure and deflection.Specifically
For, it is to represent screen as solid line in figure 2 if the feedback signal that PLC is received shows that pressure continues to increase
It is intact, then PLC keeps operating with regard to controlled motor；And once held when the PLC feedback signals received show pressure several times
It is continuous decline if, be that to represent screen damaged, then PLC is stalled with regard to controlled motor and recorded pressure as shown in phantom in Figure 2
Power size and compression number.Thus by using the difference of intact screen and the pressure-deformation amount curve of damaged screen
Part, Intellisense is advantageously carried out, so as to judge the operating and shutdown of simultaneously controlled motor.
In pressure test sequence, it is possible to occur the situation that pressure does not increase and risen with deflection once in a while, so,
In order to prevent judging by accident, we avoid the problem by being preset to, as a preferred embodiment, the feedback signal received as PLC
If showing 5-15 pressure continuous decrease, controlled motor stalls and records pressure size and compression number.
The basic principles, principal features and advantages of the present invention have been shown and described above.The technical staff of the industry should
Understand, the invention is not limited in any way for embodiment, all technologies obtained by the way of equivalent substitution or equivalent transformation
Scheme, all fall within protection scope of the present invention.
