The invention is suitable for the technical field of circuit board detection, and provides a circuit board online double-sided detection method to solve a problem that a transfer step and an overturning step are needed in the detection process of a circuit board in the prior art. The circuit board online double-sided detection method comprises the following steps: a conveying mechanism is arranged at the output end of a circuit board processing production line; a first optical imaging device and a second optical imaging device are respectively arranged at the opposite side surfaces of the conveying surface of the conveying mechanism; the first optical imaging device and the second optical imaging device respectively acquire image information of the front side of a circuit board and image information of the back side of the circuit board; and data processing and analysis of the image information of the front side and the image information of the back side are carried out through a data processing system. The conveying mechanism is close to a circuit board processing production line in order to prevent circuit board damages induced by the transfer step; and the first optical imaging device and the second optical imaging device respectively acquire the image information of the front side of the circuit board and the image information of the back side of the circuit board without overturning the circuit board, so the operation is simple, and the efficiency is high.
Description
technical field [0001] The invention belongs to the technical field of circuit board detection, and in particular relates to an online double-sided detection method for a circuit board and an online double-sided detection system for a circuit board using the method. Background technique [0002] With the development of technology, the size of electronic components on the printed circuit board is getting smaller and smaller, and the lines on the circuit board are getting thinner and denser. The traditional manual visual inspection can no longer meet the requirements of mass production. Therefore, , Circuit board testing equipment for automatic testing of printed circuit boards came into being. [0003] Such as figure 1 As shown, the traditional circuit board inspection equipment installs the optical imaging device A on the beam D (called the X-axis), so that the optical imaging device A can move left and right on the beam D, and the lighting system B is fixed on the vacuum a...
