Automatic capturing detection device for circuit boards and detection method

Abstract

The invention provides an automatic capturing detection device for circuit boards and a detection method. The detection method comprises the following steps of: a capturing step, that is, capturing a circuit board by a capturing unit, and putting the circuit board on a movable plate; a CCD photographing step, that is, moving the movable plate to a position below a CCD camera, and photographing the circuit board by the CCD camera; an image processing step, that is, performing analysis comparison of the picture photographed by the CCD camera by a processing unit; and a classification output step, that is, capturing the detected circuit board from the movable plate by the capturing unit, and putting the circuit board at a corresponding position. The beneficial effect of the invention mainly lies in that: detection and automatic classification of circuit boards can be realized, which saves both time and labor, and improves the detection efficiency.

Description

technical field [0001] The invention relates to an automatic grasping detection device and a detection method for circuit boards, belonging to the technical field of machinery. Background technique [0002] There are many types of circuit boards and different shapes. Generally, the circuit board is placed on the paper, and then stacked layer by layer. The position of the circuit board on the paper is often not centered or tilted. The use of general grabbing equipment will not work well due to the incorrect position of the circuit board. Grab it. The pass rate of the circuit board needs to be inspected before use, including bad points, dents, foreign objects on the board, etc. The existing methods generally use manual inspection, but the inspection efficiency is low, and at the same time, there will be missed inspections Phenomenon. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned technical problems, and provide an a...
