Abstract

The invention relates to the technical field of the detection of a connector, and particularly relates to a three-dimensional detection method, a three-dimensional detection device and a three-dimensional system for a connector contact pin. The method comprises the steps: acquiring images of the connector contact pin in two groups of cameras by utilizing the two groups of cameras; extracting characteristic parameters of the contact pin from the images, and determining pixel positions of the contact pin in the two images; judging whether the contact pin conforms to a first standard requirement or not on the basis of the characteristic parameters; and judging whether the contact pin conforms to a second standard requirement or not on the basis of the pixel positions. By adopting the method, device and the system, the high efficiency, stability and quantification in automatic detection of the connector contact pin can be realized, and the problems that the manual check speed is low, the quantitative detection is difficult to carry out stably, and the detection result is large in error can be solved.

Description

technical field [0001] The invention relates to the technical field of connector detection, in particular to a method, device and system for three-dimensional detection of connector pins. Background technique [0002] In the current communication industry, the backplane is a very important key component, and it is the physical interface to realize the normal communication of the network. There are many kinds of connectors on the backplane, and each connector has dozens of metal pins at least, and hundreds of pins at most, and the pins on the entire backplane generally have thousands of pins. The size of the needle is also relatively small, with a diameter of less than one millimeter and a length of several millimeters or tens of millimeters. The quality requirements of the pins of the connector on the backplane are very high, for example: the length deviation of the pins cannot exceed the allowable range, the pins cannot be bent, the needle tip deviation cannot exceed the a...
