Non-defective unit fan 16, defective products fan 16 are individually positioned in non-defective unit case 9 and defective product box 6 by tool arm 7.16 transport device of fan
Side is equipped with the 4th camera 8, the wind on fan conveyer 4 that the numerical control device is shot according to the 4th camera 8
The model of 16 identification fan 16 of fan, and each first detection module is configured to the 6th detection module according to the model of fan 16.
16 image of fan of 4th camera 8 acquisition is displayed for, and operator can pass through 16 image recognition of fan
Product type simultaneously confirms product type, and the numerical control module configures each detection module automatically according to product type.
Specific detection process is as follows:
Numerical control device first according to the product image of the 4th camera 8 shooting for being placed on the left side of fan conveyer 4, according to
Visual determination product specification, to correct manually if mistake, if subsequent product is consistent, it is not necessary to change again, and according to preset
Configuration parameter selectes the voltage of each power supply unit.
Fan 16 to be measured is sequentially moved to first fixed fixture 10 on index dial 23 by numerical control device control mechanical arm 7
On, the corresponding first detection module 11 of the fixed fixture 10, and startup power supply power supply unit powers on.After powering on, power supply is supplied
Answer that fan 16 can be consumed power by device and consumption current data return to numerical control device, numerical control device is according to the consumption power of passback
And consumption current data and the correlation data of storage compare and judge, to judge whether fan 16 is qualified.Meanwhile the first camera meeting
16 revolving speed of fan is read, data back is the no qualification of fan 16 with judgement to numerical control device.For example, having red below fan 16
Bright spot, the first camera 11 can be according to feux rouges frequency of occurrence, to judge 16 revolving speed of fan.In the lower section in the about middle position of fan 16,
If a red LED (light-emitting diode), when fan 16 covers LED, camera has bright spot without bright spot, camera according to
16 external form of fan can determine whether 16 the piece number of fan, in a clock, read the number of bright spot appearance, divided by the piece number of fan 16, just
Obtain the revolving speed per minute of fan 16.
Said fans 16 can be gone to the second detection module 13 by index dial 23.High pressure resistant tester, passes through high pressure after positioning
P-wire 12 connects fan, can test fan 16.If unqualified have short-circuit signal prompt, no prompt is just qualified.It is resistance to
Voltage tester is to generate a DC high pressure, generally in DC500V-DC2000V, then, surveys it and flows through electric current, a period of time is (general
It is -10 seconds 0.2 second) if flowing through electric current less than setting value is qualified product, it is unqualified if being more than to be considered as electric leakage；
Said fans 16 can be gone to third detection module (being located at 14 position of label in Fig. 1) by index dial 23.Startup power supply
After power supply unit powers on, power supply unit fan 16 can be consumed power according to setting low pressure and consumption current data returns to number
Device is controlled, to judge whether qualification.Second camera can read the super frame data of fan 16, data back to numerical control device, with
Judge whether fan 16 is qualified；And frame and 16 height of fan are compared to carry out super frame test, data back is to numerical control device, judgement
Whether fan 16 is qualified.Variation when second camera 14 can be rotated according to fan 16, obtains flabellum at a distance from camera,
It is compared at a distance from 16 frame of fan again.It is qualified product if frame is closer；If fan 16 is closer, mean that fan 16 surpasses
Frame is rejected product out.
Said fans 16 can be gone to the 4th detection module 15 by index dial 23.Fixed fixture 10 can turn along the X-axis choosing of fan
360 degree, while noise test is carried out using oscillograph.Index dial 23 can be by 16 three-sixth turn of said fans.Fixed fixture 10 can edge
Y-axis selects three-sixth turn, while carrying out noise test using oscillograph.Noise data are transferred to numerical control device by oscillograph, judge wind
Whether fan 16 is qualified.
Said fans 16 can be gone to the 5th detection module (being located at 3 position of label in Fig. 1) by index dial 23.It can be by the bottom of frame
Striking experiment hammer 3 is stretched out in portion, answers back to fan 16 with several directions, then with camera judge fan 16 and frame whether still to balance,
With judge fan 16 whether fixation.
Said fans 16 can be gone to the 6th detection module (being located at 10 position of label in Fig. 1) and repeat and start by index dial 23
Power supply unit powers on.After powering on, fan 16 can be consumed power and consumption current data passback by power supply unit
To numerical control device, numerical control device is compared according to the consumption power and consumption current data and the correlation data of storage of passback to be judged,
To judge whether fan 16 is qualified.And compared with first detection module first time measured value, the two is same or similar then qualified, instead
It is unqualified.
Product is placed non-defective unit case 9 by handling equipment after the above qualification, otherwise straightens specified defective products according to poor prognostic cause
Case 6.
Fan test is integrated in a test device, and obtains test parameter automatically using each detection module by the present invention
It completes automaticdata to compare, judges whether fan is qualified, detection accuracy is high, and efficiency is 2 to 3 times of manual testing；Simultaneously
Test station can be saved, working space is saved.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
Invention is explained in detail, those skilled in the art should understand that: it still can be to aforementioned each implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features；And these modification or
Replacement, the spirit and scope for technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution.
