In the above embodiment of the present invention, the display lamp that different colours are controlled when there are different testing results is bright, reaches
To the effect for obtaining vacuum degree measurement result directly perceived.
With reference to Fig. 3 in detail the above embodiment of the present invention is described in detail, Fig. 3 is preferred a kind of detection according to embodiments of the present invention
The flow chart of the method for equipment vacuum degree.As shown in figure 3, the above embodiment of the present invention can be realized by the following method：
Step S301：Read the initial vacuum angle value of vacuometer.
Step S302：Judge initial vacuum angle value whether less than or equal to the second predetermined threshold value.
If initial vacuum angle value is less than or equal to the second predetermined threshold value, execution step S303；If initial vacuum angle value is big
In the second predetermined threshold value, then execution step S304.
Step S303：Timer resets and reclocking, and the display lamp for controlling the first color is bright.
Wherein, the display lamp of the second color can be the display lamp of green.
Step S304：During by timer, the second Preset Time is determined.
Step S305：Read the second vacuum degree of vacuometer.
Step S306：Detect the second vacuum degree whether less than or equal to the 3rd predetermined threshold value.
If the second vacuum degree is less than or equal to the 3rd predetermined threshold value, execution step S303；If the second vacuum degree is big
In the 3rd predetermined threshold value, then execution step S307.
Step S307：After the second Preset Time is spaced, returns to perform and read initial vacuum angle value.
By above-mentioned steps self-inspection can be carried out to evacuation system after the vacuum degree measurement automatic of system,
Initial depression numerical value is read by vacuometer, and (first in XPa, i.e. above-described embodiment is preset by advance vacuum decision content
Threshold value) judge equipment under test (system workpiece) with the connection of vacuometer and sealing state (as workpiece connects intact or connects without workpiece
Connect, workpiece has leakage etc.).Alternatively, the first predetermined threshold value can be 40Pa.
Specifically, vacuometer reads initial vacuum angle value, if numerical value≤40Pa, now system may be not connected with waiting to evacuate
Workpiece, then also need further to make a decision, and then vacuometer shows green light and starts timing and judges into subsequent cycle；If vacuometer
The initial vacuum angle value of reading>40Pa, after the Preset Time of self-clocking second (such as 10 seconds), again reads off vacuum values (i.e.
Second vacuum degree) and judge whether system connects and be evacuated workpiece.If the vacuum at the end of timing in 10 seconds>40Pa, then say
Bright system has connected and has been evacuated workpiece, now lights amber light；If the second vacuum degree≤40Pa, system is still not connected with waiting to take out
Empty workpiece.
By above-mentioned steps, however, it is determined that workpiece connect serviceable condition, automatically begin to the Preset Time of timing first (Ts) and
Whether qualified automatic decision vacuum is at the end of setting time；After completing result judgement, program turns on into next circulation, real
Now automatically continuously run.Specifically, can be achieved by the steps of：
Step S308：Start timer to evacuated time timing, and it is bright to control the display lamp of the second color.
Wherein, the display lamp of the second color can be the display lamp of yellow.
Step S309：When evacuated time reaches the first Preset Time, the first vacuum degree is read.
Alternatively, the first Preset Time can be 150 seconds.
Step S310：Detect the first vacuum degree whether less than or equal to the first predetermined threshold value.
If the first vacuum degree is less than or equal to the first predetermined threshold value, execution step S311；If the first vacuum degree is big
In the first predetermined threshold value, then execution step S312.
Step S311：Timer resets reclocking, and it is bright to control the display lamp of the first color.
Step S312：Timer resets reclocking, and it is bright to control the display lamp of the 3rd color.
Wherein, the display lamp of the 3rd color can be red display lamp.
Step S313 and step S314：It is spaced the 3rd Preset Time.
Specifically, after the 3rd Preset Time is spaced, execution step S301 is returned.
Can be connected after workpiece is evacuated in decision-making system by above-mentioned steps, determine whether system in setting time
Whether interior vacuum is qualified.
Specifically, the system pump down time is preset for 150 seconds, Jing after timing 150 seconds, vacuometer reads system vacuum
Numerical value (i.e. the first vacuum degree) simultaneously judges, if the first vacuum degree>40Pa, then system vacuum is unqualified, system point azarin
Lamp and timing clearing, into subsequent cycle；If vacuum values≤40Pa, system is in the 150s evacuated times of setting
System vacuum is qualified, reaches sets requirement, and point gives a green light and timing resets, into next detection circulation.
Need it is further noted that the timing time Ts in Fig. 2 is used for system vacuum realizes that circulation is spontaneous to system
Detection, according to the size reasonable of different system equipment pumpage assessment setting timing time, it is ensured that system is in not connected workpiece
In the case of, accurately carry out system itself detection and judge.
By the above embodiment of the present invention, the automatic decision logic provided using the present invention, cancel artificial operational motion
And subjective judgment, realize the vacuum automatic detection in setting time section and judgement.Specifically, without the need under artificial operational order
Carry out automatic identification system and evacuate work status；System realize can continuously self-clocking, without the need for manually opening (or end)
Clocked operation；Further, the programmed logic of system is realized sentencing in the accurate automatic checkout system vacuum output of setting time point
Determine result, and detect effective automatic cycling operating, by above-described embodiment, improve the automatization level of vacuum degree measurement, keep away
The uncontrolled factor such as artificial judgment mistake is exempted from.
The embodiment of the present invention additionally provides a kind of device of testing equipment vacuum.The device can pass through above-described embodiment
In the method for testing equipment vacuum realize its function.It should be noted that the testing equipment vacuum of the embodiment of the present invention
