On-line automatic testing system in production of optical module

Abstract

The invention relates to an on-line automatic testing system in production of an optical module. The on-line automatic testing system is suitable for a testing platform for an automatic production line of the optical module; a control computer operates multiple kinds of testing instruments which comprise an oscilloscope, a light source, an optical attenuator, an error code tester, an optical power meter, a spectroanalysis instrument, a pattern generator and the like; and the automatic testing system modularizes all details, and divides instrument and equipment control, debugging, measurement,calibration, insertion removal judgment, data storage and data processing into independent modules, and a data exchange mechanism in each module is refined and packaged. All modules are spliced and combined in a mode of a frame structure to ensure that all the modules have high flexibility and generality, and the system can become a new automatic testing system by only changing one of the modules. The system integrates a plurality of processes of debugging, testing, calibration and the like, and the phenomenon that a rejected product enters the next process due to personal factors is avoided as much as possible; and the system is easy to operate, improves the production efficiency and test accuracy, and makes data tracing possible.

Description

technical field [0001] The invention relates to an online automatic test system in the production of optical modules. Background technique [0002] In the past manual test system, the test steps before the environmental experiment were divided into four steps: module debugging, parameter testing, module calibration and inspection and calibration, and after the environmental experiment were divided into three steps: parameter testing, inspection and calibration, and insertion and release judgment. The judgment on whether the product test results are qualified or not depends on the operators on the production line. At this time, human errors are prone to occur. Due to the lack of support from test data, such errors are difficult to be found, and it will also increase the need for subsequent judgments and problems. Difficulty of handling. In addition, the manual test system cannot compensate for the existing systematic errors, resulting in large measurement errors. Moreover, ...

Problems solved by technology

[0007] 2. Debugging is not associated with the database, and historical data cannot be traced

[0008] 3. A single point is often used for internal calibration, and inaccurate calibration will occur when the linearity of the device is not good

[0009] 4. The existing insertion release judgment test uses high and low levels as the basis for judging whether the insertion release judgment is correct. If the module is not completely damaged, the correct result cannot be measured

[0011] 6. The test system lacks reusability, and the application product line is single

It is difficult to develop a new test system based on the existing test system, which increases the development time of the new system
