An automatic line width and distance measuring machine

Abstract

The invention provides an automatic line width and line distance measuring machine. The line width and line distance measuring machine includes a detection device, a transport device, a calibration device, an abutment device, a collection device, a rotating device, an adjustment device and a processor. The detection device is structured as Detect the parameters of the circuit board; the transportation device is configured to transport the circuit board to be detected; the calibration device is configured to calibrate each position of the circuit board, and cooperate with the detection device to detect the circuit board; the abutment device is constructed To adjust the position of the calibration device; the acquisition device is configured to collect data based on the detection device and the calibration device; the rotation device is configured to adjust the angle of the circuit board; the adjustment device is configured to adjust the position of the detection device . In the present invention, the sensing board and the path collector are used in cooperation with each other, so that the entire device can detect the moving path of the circuit board and the indicating head during the detection process.

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] In the prior art, the measurement error caused by light source attenuation is eliminated through regular 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 becomes weaker, which eventually leads to poor test accuracy. [0003] Another typical line width measuring machine disclosed in the prior art of CN203454970U, because each type of TFT liquid crystal display all needs to prepare special SEM standard sheet or standard mask plate separately, therefore, the procedure is loaded down with trivial details and realize relatively Difficult; the service life of the light source of the line width measuring machine is generall...

AI Technical Summary

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
