The job order when testing the focal length of photographic head 200 for the ATE 100 of above-mentioned photographic head is as follows: works as phase
Photographic head 200 on the installation portion 52 being arranged on focusing part 4 lower section is completed to test, cylinder 232 starts, drive guide pillar 231 to move
Go out location hole, start rotary drive 6, drive rotation platform 5 to rotate 180 ° of installation portions making in the loading and unloading area in outside
52 move to test section, after the installation portion 52 in test section is located at the lower section of focusing part 4, is again started up cylinder 232, drives
Guide pillar 231 is inserted into positioning in the hole makes rotation platform 5 position, then, image acquisition device move in place upper under the driving of regulating part move,
It is connected with camera signals, then, control focusing model part 3, focusing part 4 and image acquisition device to be pointed to by test software
Photographic head 200 in test section is tested, and after the completion of test, image acquisition device moves in place and moves down under the driving of regulating part,
So that image acquisition device is disconnected with photographic head, and finally repeat abovementioned steps.Wherein, in focusing model part 3, focusing part 4 and figure
While photographic head 200 test as harvester, removal has completed the photographic head 200 tested and has pacified on installation portion 52
Load onto new photographic head to be measured 200.
In addition, the ATE 100 of this photographic head also includes the LED light source part 10 being fixed on workbench 2, should
LED light source part 10 is fixed on track base 20.This track base 20 is fixed on workbench 2, and track base 20 includes flat with workbench 2
The guide rail 201 of row setting, the support column 202 of supporting guide 201, it is arranged on guide rail 201 and can be along the slip of guide rail 201 movement
Seat 203 and the translation motor 204 driving described sliding seat 203 movement on guide rail 201, this guide rail 201 prolongs along workbench 2 about
Stretch, sliding seat 203 can horizontally slip on guide rail 201.Described LED light source part 10 is fixed on sliding seat 203, LED light source part
10 pass through the mobile surface to rotation platform 5 of sliding seat 203, and one of installation portion 52 is blocked.LED light source part 10 in order to
Whether image after photographic head 200 imaging for the detection has stain and dirty etc., completes image measurement.Focusing model part 3 in order to
The focusing of test photographic head 200, completes focusing test.Above-mentioned image measurement and focusing are tested when using it is impossible to carry out simultaneously
Test, when carrying out focusing test, LED light source part 10 passes through the mobile right side to rotation platform 5 of track base 20 or left side, no
Block rotation platform 5, focusing part 4 is displaced downwardly to suitable position under the driving of lowering or hoisting gear 8, then carries out focusing test;When
When carrying out image measurement, focusing part 4 moves up under the driving of lowering or hoisting gear 8, and its level height is higher than LED light source part 10,
Then pass through track base 20 by mobile for LED light source part 10 underface to part 4 of focusing, that is, movement be provided with to one of them to be measured
The installation portion 52 of examination photographic head 200 relatively above, carries out image measurement then.It is provided with cable drag chain in described test chamber 11
30, to collect the cable of lifting motor 83 and translation motor 204, make test chamber 11 clean and tidy.
Refer to Fig. 8 and combine Fig. 1 to 7, the automatic test approach of the photographic head of the present invention, for above-mentioned photographic head from
The control of dynamic test equipment 100, wherein, the ATE 100 of described photographic head includes test section, image acquisition device, use
With the rotation platform 5 clamping photographic head 200, the focusing part 4 being arranged on test section and the focusing model portion being located at test section side
Part 3.The clamp portion 53 of at least two clamping photographic head 200, the quantity of described image harvester are provided with described rotation platform 5
The quantity setting of corresponding clamp portion 53.It is provided with style table 35, described style table 35 has some in described focusing model part 3
The test block 351,352 of two kinds of colors of adjacent spaces setting, the shape of described test block 351,352 is parallelogram,
In described two test block 351,352 a kind of test block be shaped as rhombus, another kind of test block be shaped as square, its
In, the Minimum Internal Angle of rhombus is 80 °, and foursquare base is 5 ° with the angle on the base of style table 35.Described photographic head from
Dynamic method of testing includes s1 to s6.
S1: in loading and unloading area, photographic head 200 to be measured is installed on rotation platform 5, starts rotation platform 5, to be measured
Photographic head 200 goes to test section from loading and unloading area.When rotation platform 5 goes to test section, photographic head 200 to be measured is towards style table
35.In the present embodiment, the clamp portion 53 of clamping photographic head 200 adopts four, so, four clamp portion 53 go to test simultaneously
Area.
S2: image acquisition device is connected with the photographic head 200 to be measured on rotation platform 5.Here is it should be understood that front
State in embodiment, each image acquisition device corresponds in a clamp portion 53 photographic head 200 respectively.
S3: product initializes, and image acquisition device gathers image.
S4: focusing test, whether test photographic head 200 reaches specification standards?As qualified, focusing terminates;As otherwise to taking the photograph
Focal length as 200 is adjusted and is tested again, judges again to test whether photographic head 200 reaches specification standards, if
Qualified, focusing terminates, otherwise again Focussing and test until qualified, or until after exceeding focusing step test still
Not up to focusing specification standards, then focusing terminates.Because clamp portion 53 adopts four, so, the shooting in four clamp portion 53
200 carry out focusing test simultaneously, and its part 4 that passes through to focus realizes the Focussing of photographic head 200.
S5: be again started up rotation platform 5, the photographic head 200 completing to test is gone to loading and unloading area from test section, display is surveyed
Test result;
S6: the photographic head 200 completing to test is removed and repeat step s1 to s5 in loading and unloading area.
Also include between above-mentioned steps s4 and s5: focusing carries out image measurement after terminating again.When carrying out image measurement, position
Photographic head 200 in test section carries out image measurement simultaneously.
In described step s4, when focusing is focused, its focusing mode is: according to obtain image definition Lai
Judge the angle of single step focusing, when relatively obscuring, the angle of single step focusing is larger, and when close to articulation point, single step is focused
Angle less.
By the automatic test approach of photographic head is applied on the ATE 100 of photographic head, it is achieved thereby that
Aulomatizeted Detect, improves work efficiency and measuring accuracy.
In sum, cooperating due to focusing model part 3, focusing part 4, rotation platform 5 and image acquisition device, real
Show Aulomatizeted Detect, improve work efficiency and accuracy of detection.In addition, by arranging multiple fixations on each installation portion 52
The clamp portion 53 of photographic head 200, makes multiple stations share a model, completes the test of multiple photographic head 200, further simultaneously
Improve work efficiency.
The above is only the preferred embodiment of the present invention, is not limited to the present invention it is noted that for this skill
For the those of ordinary skill in art field, on the premise of without departing from the technology of the present invention principle, can also make some improve and
Modification, these improve and modification also should be regarded as protection scope of the present invention.
