CIS detecting device for circuit boards

Abstract

The invention discloses a CIS detecting device for circuit boards. The CIS detecting device comprises CIS line array cameras, linear light sources and a circuit board conveying mechanism; the linear light sources are arranged at the two sides of the CIS line array cameras, the optical axes of the CIS line array cameras and main light of the linear light sources intersect on the same straight lineof the circuit boards on the circuit board conveying mechanism; the length of the CIS line array cameras is the same as that of the linear light sources, the linear light sources are installed at thebottoms of the CIS line array cameras, and the CIS line array cameras and the linear light sources stretch across the circuit board conveying mechanism. The CIS line array cameras can simultaneously take continuous images of a portion which is located below the cameras and is comparable to the camera in length. When the number of the circuit boards needs which need to be simultaneously detected ischanged, the number of the circuit boards can be increased or decreased by adjusting the distance between every two circuit boards, so that the number of the detected circuit boards is flexibly set within a certain range without being influenced by the size of the circuit boards. Therefore, the application flexibility of the detecting device is higher, and the equipment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of circuit board detection, in particular to a CIS detection device for circuit boards. Background technique [0002] With the development of electronic technology, the functions of various electronic products are constantly upgraded, and there are higher requirements for the production and testing process of circuit boards. For example, the number of layers of circuit boards is increasing, the internal circuits are becoming denser, the line width and line spacing are smaller, and the detection accuracy is required to be high, etc. [0003] The circuit board inspection device is an advanced online inspection technology. It obtains the image information of the surface of the tested part and compares it with the image information of the qualified part, so as to detect whether the tested part is qualified. Due to the complexity of PCB boards, more and more design circuits, and more and more layers, the use of ...
