Method, device, equipment and storage medium for determining test files in board test

Abstract

The invention discloses a method, a device, a device and a storage medium for determining test files in a board test, and the image of the board to be inspected in the collected characteristic area is used as the image to be inspected, wherein the characteristic area is an automatic optical detection AOI The pre-determined area in the inspection station of the equipment; determine the similarity between the image to be inspected and each standard image, where the standard image is the image formed by the sample board in the characteristic area; determine the test file corresponding to the board to be inspected according to the similarity. This technical solution pre-determines a characteristic area in the detection station of the AOI equipment, takes pictures of the boards to be inspected entering the characteristic area, and calculates the similarity with the image of the sample board in the characteristic area, and determines the test file according to the similarity And check the board to be tested. It solves the problem of needing to take multiple photos of the board to be inspected, realizes that only one photo is taken, and the corresponding inspection file can be selected, and the test efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of optical measurement, and in particular to a method, device, equipment and storage medium for determining a test file in a board test. Background technique [0002] Automated Optical Inspection (AOI) is a device based on optical principles to detect common defects in the production process of Printed Circuit Board (PCB) board welding. In the actual production process, multiple types of different PCB boards may be produced simultaneously on the same production line. Therefore, before the AOI equipment detects the PCB board, it is necessary to determine the test file corresponding to the current board to be inspected. [0003] In the prior art, the common way to determine the test files of the boards to be inspected is to predetermine the positions of the Mark points in each inspection file. When the boards to be inspected enter the AOI equipment, the AOI equipment will correspond ...

Problems solved by technology

[0004] However, in the prior art, determining the corresponding test file requires multiple photographs of the board to be inspected, and the number of photographs is determined by the number of test files in the AOI equipment, resulting in long test time and low efficiency
