Connector dimension vision measurement method

Abstract

The invention discloses a connector dimension vision measurement method. The connector dimension vision measurement method comprises steps that, template contour characteristics of a standard workpiece are established; a to-be-detected workpiece is selected, and contour characteristics of the to-be-detected workpiece are established; the template contour characteristics of a standard workpiece and the contour characteristics of the to-be-detected workpiece are contrasted to determine similarity of the two, if the similarity of the two reaches a set value, a target quantity is satisfied, the to-be-detected workpiece is qualified preliminarily, dimension characteristic parameter measurement processing is further carried out, and whether the to-be-detected workpiece is qualified is further determined; if requirements are not satisfied, the to-be-detected workpiece is not qualified. According to the method referring to the dimension vision measurement field of a connector used in a circuit, whether the connector workpiece is qualified can be rapidly detected, the workpiece after detection has high workpiece precision, and the detection result has strong reliability.

Description

technical field [0001] The invention relates to the field of visual measurement of connectors used in circuits, in particular to a method for visual measurement of connector dimensions.

[0003] Traditional workpiece detection methods mainly use vernier calipers or screw micrometers for manual measurement. This measurement method has the disadvantages of slow measurement speed and low measurement accuracy, which is not conducive to improving the automatic detection speed of the assembly line. and accuracy requirements

[0004] Some high-precision connectors are often used in the circuit. They are widely used in various fields. They often have strict requirements on the specifications and parameters of the manufactured workpieces. If any of these parameters do not meet the requirements, they cannot be used. If only using The above-mentioned manual detection method obviously cannot meet the high-precision requirements. Although a simple machine vision method has been developed to replace the manual judgment of whether the workpiece is qualified, if this technology is applied to this type of circuit connector, it is only Simply compare the image shape of the standard workpiece and the new workpiece to judge whether it is qualified, and it is impossible to consider other parameter information of the connector. Obviously, the workpiece obtained by this method cannot be guaranteed to be a high-precision qualified workpiece
