Relationship, first umber of pulse, second umber of pulse and the crawl calibration pulse number；
The main control module 21 further include: the pulse judging unit 212 that is connect with the database 211, poll units
213, control unit 214, control unit to be detected 215, test position control unit 216, safe range judging unit 217 are grabbed
And unit of testing and controlling 218；
The pulse judging unit 212, when for judging that first umber of pulse is less than the crawl calibration pulse number, control
It makes the handling module 24 and is moved to the crawl coordinate；
The poll units 213, are polled for the pulse value to the coding module, detect second pulse
When number subtracts first umber of pulse equal to the crawl calibration pulse number, the fetching instruction is issued；
The crawl control unit 214 is grabbed for controlling the handling module 24 according to the fetching instruction；
The control unit to be detected 215 controls the crawl when for detecting that the handling module 24 is grabbed successfully
Module 24 is moved to the position to be detected；
The test position control unit 216, for detecting the test position guiding module 25 to the end to be measured
After end 30 successfully identifies, the position coordinates of the shielded box 261 of current idle are obtained, and using the position coordinates as described in
Test position coordinate is sent to the crawl control module；
The safe range judging unit 217, for carrying out analysis to the test position coordinate, in the test
When position coordinates are in the safe range, the test instruction to be received such as transmission；
The unit of testing and controlling 218, after receiving the ready information of the test machine module 26, to the survey
Test-run a machine module 26 sends test instruction, and receives the test that the test machine module 26 is fed back and complete instruction.
Specifically, test program starts to test referring to Fig. 6, start two threads, thread 1, the crawl guiding module 22
After the detection unit 221 detects the terminal to be measured 30, controls first camera unit 222 and take pictures, the master control
Module 21 reads the umber of pulse of the encoder 231 instantly, if taking pictures ok, the mapping for recording current terminal to be measured 30 is mechanical
The umber of pulse when coordinate of hand 241 and crawl, and storing it in the chained list queue that the main control module 21 is set, such as Fig. 7,
Illustratively, chained list queue setting can store 8 groups of data, when first camera unit 222 photographed the 9th terminal 30 to be measured
When, remove gauge outfit, be inserted into new data in tail of the queue, such chained list queue remain 8 can currently grabbed it is described to be measured
The coordinate and pulse information of terminal 30.If taking pictures NG, continue to clap next 30 object of terminal to be measured, the chained list team
In column, x represents x-axis coordinate value, and y represents y-axis coordinate value, and θ represents angle, and p represents corresponding umber of pulse when shooting；Thread 2, is opened
Beginning searches the chained list queue of 222 coordinate information of the first camera unit, begins looking for from gauge outfit, takes out in chained list queue
P1, the i.e. number of pulses of gauge outfit, the pulse judging unit 212 judge whether it is less than the number of pulses of crawl normal bit, such as
Fruit, which is less than, then to say the word to manipulator 241, allows it to be moved to above the coordinate that first camera unit 222 provides and waits, institute
The pulse value for stating the cycle detection encoder 231 of poll units 213 described in main control module 21, until current PRF value subtracts P1 etc.
In the crawl calibration pulse number, the crawl control unit 214 says the word to be grabbed to manipulator 241, the institute if grabbing successfully
It states control unit 215 to be detected and sends commands to manipulator 241, it is allowed to be moved to above 251 position of the second camera unit,
If crawl failure, continues to search the chained list queue of level-one camera coordinates information, steps be repeated alternatively until and successfully grab.Work as institute
It states handling module 24 and the terminal 30 to be measured is moved to 251 top of the second camera unit, take pictures and grab Q-character, if at
Function identification, the test position control unit 216 then provide in the test machine module 26 eight corresponding to eight shielded boxes 261
A position coordinates (X, Y, θ), the safe range judging unit 217 can carry out the judgement of safe range to eight coordinate positions,
Meet safe range then to continue in next step, if being moved to manipulator 241 beyond the transmission order of safe range primary control program specified
Terminal 30 to be measured is put down in position.Reacquire information in chained list queue；If 251 identification feature of the second camera unit failure
The main control module 21 also sends order and manipulator 241 is moved to designated position, puts down object under test, reacquires chained list team
Information in column.The test mode of oneself is written in database 211 eight shielded boxes 261, the test list of the main control module 21
The database is written in test result by the terminal operating test program to be measured in first 210 pairs of shielded boxes, test cell 210
In 211, the then opening shielded box 261 of completion is tested, waits manipulator 241 to take plate, the unit of testing and controlling 218 searches number
According to library 211, which station test is completed, and is sent commands to manipulator 241 and be moved to corresponding crawl position, and test is taken out
The object of completion, is then placed in object to be tested, and the unit of testing and controlling 218 sends order " close " to manipulator
241, it closes shielded box 261 and automatically begins to test.The test result processing unit 212 searches currently quilt in database 211
The test result of object is taken out, if test PASS, primary control program send commands to manipulator 241, the object that test is completed is moved
It moves non-defective unit position and places.If testing Fail, the unit of testing and controlling 218 sends commands to manipulator 241, will test
At object be moved to defective products position and place.
