Automatic optical detection method

Abstract

The invention discloses an automatic optical detection method. The method comprises the following steps: conveying a to-be-detected object to a detection positioning point; after the to-be-detected object reaches the detection positioning point, starting a bar code scanner to read a bar code of the to-be-detected object so as to obtain a serial number of the to-be-detected object; selecting a first image collector or a second image collector to collect the image of the to-be-detected object, wherein the first image collector has an image processing function, and the second image collector doesnot have the image processing function; collecting the image of the to-be-detected object, and interpreting the image of the to-be-detected object through the first image collector or the second image collector; and transmitting the image data and the interpretation result to a terminal. Through the automatic optical detection method provided by the invention, the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of optical detection, in particular to an automatic optical detection method. Background technique [0002] As far as Automatic Optical Inspection (AOI) is concerned, the traditional inspection step is to first use the conveyor belt to transport the object to be tested (such as a circuit board) to the inspection positioning point, and then pass through the image collector set at the detection positioning point. After collecting the image of the object to be tested, the collected image data is sent to the computer, and the operator performs subsequent image storage and defect interpretation. [0003] However, sometimes in order to respond to different product requirements, a variety of different image collectors (such as CCD, CMOS or Webcam) or multiple sets of control systems may be configured on the production site, but there are often system differences between these different image collectors. Compatibility issues...

[0003] However, sometimes in order to respond to different product requirements, a variety of different image collectors (such as CCD, CMOS or Webcam) or multiple control systems may be configured on the production site, but there are often system differences between these different image collectors. Compatibility issues, in addition to easily causing trouble for maintenance personnel and increasing maintenance costs, it is also difficult to work together to form a consistent production process, which will inevitably have a negative impact on production efficiency and product yield.
