Embodiment Construction

[0036] A preferred embodiment of the present invention, the system structure is as figure 1 As shown, it is composed of a central server 101 and several super-resolution detection terminals 102, and the central server is connected to each super-resolution detection terminal through a wired or wireless communication network. The super-resolution detection terminal is installed on the inspection point of the conveyor belt between the two processes. In normal operation, the super-resolution detection terminal performs image acquisition and super-resolution reconstruction on the circuit board passing the inspection point on the conveyor belt, and then passes through the communication network The reconstructed high-resolution image of the circuit board to be inspected area is transmitted to the central server; the central server matches the high-resolution image of the circuit board to be inspected area collected at each inspection point with the corresponding standard template, and d...

Abstract

The invention relates to a circuit-board element installing/welding quality detection method based on super-resolution image reconstruction. The method comprises the steps of utilizing a camera array and the motion of a conveyor belt to perform super-resolution image reconstruction on an area to be detected of a circuit board, and judging whether the installation and welding of elements are qualified according to reconstructed high-resolution images of the area to be detected on the circuit board. A detection system for realizing the method consists of a central server and a plurality of super-resolution detection ends, wherein the central server is connected with every super-resolution detection end; the super-resolution detection ends acquire the images of the area to be detected of the circuit board at detection points, perform super-resolution image reconstruction and then transmit the images to the central server; and the central server matches every high-resolution image in the area to be detected of the circuit board, which is acquired at the detection points, with a corresponding standard template, so as to detect unqualified elements or welding spots.

Description

Technical field [0001] The invention relates to a method and system for detecting the production quality of a circuit board, in particular to a method and system for detecting the mounting / welding quality of circuit board components based on super-resolution image reconstruction.
