Problems solved by technology

In this process, when the CIS industrial camera is pushed forward and then stops, the trigger device will mistakenly think that the CIS industrial camera has been positioned and output a trigger pulse to trigger the image acquisition device, so as to perform "measurement-comparison" on the servo motor. ——In the process of "executing" positioning, the image acquisition device will be triggered repeatedly. When the servo motor stops, multiple white or black lines appear in the image, resulting in the failure of image stitching

Embodiment Construction

[0026] All the features disclosed in this specification, or all disclosed methods or steps in the process, except for mutually exclusive features and / or steps, can be combined in any manner.

[0027] Any feature disclosed in this specification, unless specifically stated, can be replaced by other equivalent or equivalent alternative features. That is, unless otherwise stated, each feature is just one example of a series of equivalent or similar features.

[0028] Those skilled in the art know that an encoder or grating ruler is a displacement sensor, which is used to convert angular displacement or linear displacement into periodic electrical signals, and then convert this electrical signal into count pulses, and use the number of pulses to represent displacement the size of. The encoder or grating ruler used in the present invention has two count pulse outputs. The two count pulses are the same except for the different phases. The phases of the two pulses successively reflect the...

Abstract

The invention discloses an image acquisition external trigger signal debounce device, relates to industrial control technology, and proposes the invention in order to reduce the obstacles to the use of image splicing equipment caused by jitter. The technical solution adopted in the present invention includes: the first input noise suppression circuit and the second input noise suppression circuit are connected to the input phase detection circuit, and the input phase detection circuit, the input pulse calculation circuit and the image acquisition trigger circuit are sequentially connected.

Description

Technical field [0001] The invention relates to industrial control technology, in particular to an image acquisition external trigger signal debounce device of a CIS industrial camera in an industrial production line. Background technique [0002] In recent years, the overall processing level of various industries in my country has been continuously improved. High-quality processing and precision instrument processing occupy an increasing proportion of the processing industry, and the requirements for optical inspection equipment are also increasing. The optical inspection equipment on the production line uses high-sensitivity image sensors to image the surface of the product to obtain the original surface information of the product. Through the analysis and processing of the original surface information, the purpose of detecting whether the product is qualified is achieved. At present, the popularization and use of Python series ultra-wide format CIS industrial cameras in the te...
