Problems solved by technology

There may be dust and rust on the wires. The appearance of the wires of different lines is not exactly the same, and the wires do not have a large enough texture, so it is difficult to perform conventional visual distance measurement, and the detection accuracy is poor, so it cannot be automatically identified; big intrusion
[0005] In order to solve the common problems in the field of low automation, time-consuming and laborious, poor calibration accuracy, inability to automatically identify, large interference, inability to adjust detection accuracy and inability to correct attenuation parameters, etc., the present invention is made

Description

technical field [0001] The invention relates to the technical field of circuit board detection, in particular to an automatic line width and line distance measuring machine. Background technique [0002] The prior art eliminates measurement errors caused by light source attenuation through periodic manual calibration. At present, the light source is usually a halogen lamp, but due to its limited service life and continuous attenuation of illuminance during use, the amount of light reaching the test lens is weakened, which ultimately leads to poor test accuracy. [0003] Another typical line width measuring machine disclosed in the prior art of CN203454970U, since each type of TFT liquid crystal display needs to prepare a special SEM standard sheet or standard mask separately, the procedure is cumbersome and the realization is relatively low. Difficult; the service life of the light source of the line width measuring machine is generally about 2000 hours. Since its attenuati...
