An online optical detector

Abstract

The invention discloses an on-line optical detector. Four large columns are fixed on the frame. The four large columns are distributed on the four vertices of the same rectangle, and the four large columns are arranged from bottom to top between the four large columns. There are five components in sequence, which are respectively the lower camera component, the lower light source component, the pressing component, the upper light source component and the upper camera component. The present invention adopts the combination of the upper and lower light sources and the corresponding camera components, so that the image information of the PCB board and the lower surface to be detected can be obtained at the same time, so that the detection efficiency can be doubled, and the traditional detection is eliminated. The trouble of turning over the detection instrument; at the same time, the present invention effectively improves the accuracy of the acquired image information through the setting of the pressing component and the addition of two enhanced light sources in each light source component, thereby improving the detection accuracy of the detector, each The three light sources in the light source assembly have a good heat dissipation effect, and the service life is reliably guaranteed.

Description

technical field [0001] The invention belongs to the field of optical detection, and in particular relates to an on-line optical detection instrument. Background technique [0002] The on-line optical detector is an advanced on-line 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 to detect whether the tested part is qualified. At present, online optical detectors are used in a wide range of fields, such as to detect PCB boards (printed circuit boards). Due to the complexity of PCB boards, more and more design circuits, and more and more layers, online optical detectors are used The detector to detect the PCB board is far more mature and efficient than the manual detection method, which is more conducive to ensuring the detection accuracy and controlling the product quality.

Problems solved by technology

[0003] When the existing online optical detector detects, the PCB board is placed on a flat plate, one surface of the PCB board is detected first, and then the PCB board is turned over to detect the other surface of the PCB board, so that the PCB board cannot be detected at the same time. Two surfaces, resulting in low detection efficiency; in addition, due to slight bending of the tested part, insufficient light intensity of the light source and shadow areas, etc., this will affect the accuracy of the acquired image information, thereby affecting Detection accuracy
