Visual detection equipment of circuit board

Abstract

The invention discloses visual detection equipment of a circuit board. The visual detection equipment of the circuit board comprises a bearing plate and a control system, a conveyor trough arranged on the bearing plate, a conveyor belt clamped in the conveyor trough and used for conveying a supplied to-be-detected circuit board, a first visual detection device, a second visual detection device, a finished product collection device and a defective product collection device, wherein the first visual detection device comprises a first CCD (charge coupled device) imaging system and a first blocking mechanism; the second visual detection device comprises a second CCD imaging system and a second blocking mechanism; the finished product collection device is used for collecting finished circuit boards after detection; and the defective product collection device comprises a defective product rejecting manipulator and a defective product collection conveyor belt used for collecting defective products. Compared with the prior art, only one conveyor belt is adopted for the detection process, so that the cost is saved greatly, and the visual detection equipment of the circuit board can perform detection on a first surface and a second surface of the circuit board respectively, the detection covering range is large, and the detection speed is high.

Description

technical field [0001] The invention relates to circuit board detection, in particular to a circuit board visual detection device. Background technique [0002] In the prior art, after soldering and packaging the various components of the circuit board, it is necessary to carry out some defect detection on the circuit board to ensure that the output circuit board is a finished product, so as to complete the installation or follow-up of the circuit board for the post station. Therefore, the inspection of the circuit board is very important. Because the circuit board circuit is relatively complicated, manual inspection is generally required. The disadvantages are: it is easy to miss inspection and the detection speed is slow. , Also due to human factors, resulting in the mixing of defective products and finished products, etc., making the detection efficiency low and inaccurate. [0003] Based on this, it is very necessary to design a visual inspection equipment for circuit b...
