Horizontal CCD (charge-coupled device) two-sided line scanning system

A scanning system and horizontal scanning technology, applied in the direction of measuring devices, material analysis through optical means, instruments, etc., can solve the problem of circular boards, special-shaped boards that cannot be scanned vertically, and cannot be cleaned by adding adhesive layer rollers to the board surface, and soft boards. Problems such as inability to scan upright can achieve the effect of reducing manpower, increasing output, and reducing false positives

Problems solved by technology

With this method, because it belongs to the vertical transportation method, only one piece of scanned object can be transported at a time, and there are high requirements for the shape, hardness and thickness of the scanned object. Shaped boards and special-shaped boards cannot be scanned upright
And due to the structural limitations of vertical scanning, the scanned object is transported vertically, and it is impossible to add adhesive rollers to clean the board surface in an automated way, which increases the false positive rate, increases manual confirmation time, and reduces output efficiency

Abstract

The invention relates to a horizontal CCD (charge-coupled device) two-sided line scanning system, and belongs to the technical field of machine vision image processing. The system comprises a horizontal scanning system support. The both ends of the horizontal scanning system support are provided with an extracting mechanism and a discharging mechanism; an upper CCD scanning mechanism is disposed between the extracting mechanism and the discharging mechanism; a first LED (light-emitting diode) controllable illuminant lighting device is disposed below the upper CCD scanning mechanism; a conveying device A and a conveying device B are disposed below the first LED controllable illuminant lighting device; a scanning opening is disposed between the conveying device A and the conveying device B; a second LED controllable illuminant lighting device is disposed below the scanning opening, and a lower CCD scanning mechanism is disposed below the second LED controllable illuminant lighting device. By using horizontal way to perform two-sided scanning, the system can scan multiple items side by side at one time; the items can be allowed to roll and continuously transport and a next plate can enter into the scanning area without waiting for the completion of one transport period, and therefore, production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of machine vision image processing, and in particular relates to a horizontal CCD double-sided line scanning system. Background technique [0002] At present, in the field of automated systems for PCB board scanning and testing in China, most systems scan PCB structures in a vertical vertical transport mode, or flip over to scan both sides of the board to obtain images. With this method, because it belongs to the vertical transportation method, only one piece of scanned object can be transported at a time, and there are high requirements for the shape, hardness and thickness of the scanned object. Shaped boards and special-shaped boards cannot be scanned upright. And due to the structural limitations of vertical scanning, the scanned object is transported vertically, and it is impossible to add adhesive rollers to clean the board surface in an automated way, which increases the false positive rate, increase...
