Fig. 1 is the composition structured flowchart of the electronic product test production line of one embodiment of the invention.As it is shown in figure 1, it is described
Electronic product test production line 10, is primarily adapted for use in printed circuit board (PCB) (Printed Circuit Board, PCB) or mainboard
The on-line testing of (Mother Board), specifically include control device 11 and with control device 11 be connected detection device 12,
Adjusting apparatus 13, transporter 14 and testing station 15.The process that implements of above-mentioned electronic product test production line 10 includes:
Before test, described detection device 12 is controlling automatically to read under device 11 controls the coding information on electronic product
And feed back to control device 11；Described control device 11 is according to the kind of the described coding information automatic decision electronic product received
Class, and it is automatically adjusted transporter 14 according to the kind control adjusting apparatus 13 of electronic product, so that transporter 14 is according to working as
The kind of front electronic product transmits electronic product；Meanwhile, described control device 11 is transferred always according to the kind of electronic product
The test plan that electronic product is corresponding, so that testing station 15 is produced from the electronics of transporter 14 according to this test scenario test
Product.
The application of above-mentioned electronic product test production line 10, it is ensured that on same production line, variety classes electronic product exists
The automatization of line test, it is to avoid need to artificially log in MES system (production informationization management system) during each test to select really
Recognize model information, transfer corresponding test plan and the trouble of manual manipulation adjusting apparatus regulation transporter, with existing skill
Art is compared, and automaticity and the testing efficiency of electronic product test production line 10 on-line testing of the present embodiment are high, and, survey
Examination process is omnidistance too much to be participated in without artificial, and easy to operate, human cost is low.Especially, every time before test, described detection dress
Putting 12 and can automatically read the coding information that have recorded Current electronic product category, afterwards, described control device 11 judges automatically
The kind of Current electronic product, and automatically control adjusting apparatus 13 according to the electronics categories that obtains and regulate transporter 14
State, so, it is achieved that the function of self-adaptative adjustment transporter 14, compared with existing artificial manipulation regulation transporter, letter
Change the operating process of test, implemented more convenient.More particularly, described control device 11 determined Current electronic product
After kind, the most automatically transfer (transferring from internal storage device or External memory equipment) and test plan accordingly, so that test
Stand and 15 automatically test electronic product according to this test plan, so, it is not necessary to manpower intervention is logined MES system and selected to confirm type
Test plan, it is thereby achieved that automatically transfer test plan and automatically perform the purpose of test according to this test plan, tested
Cheng Gengwei is easy.
Preferably, described control device 11 chooses the survey of a correspondence in multiple testing stations 15 always according to the kind of electronic product
Examination station 15, to test Current electronic product, the most described control device by the testing station 15 corresponding with this electronics categories
11 transmission standbies are to a certain testing station 15, to notify this testing station 15 setup test.Wherein, each testing station 15 is in order to survey
A kind of electronic product of examination.For brevity, following example, using multiple testing station 15 as signal, further describe this
Bright electronic product test production line 10.
Holding above-mentioned, during test, the electronic product of supplied materials is passed under controlling device 11 control by described transporter 13 automatically
