Aoi retractable board machine and retractable board method with sticky dust, flipping and coding functions

Abstract

The present invention relates to an AOI retractable board machine and a board retractable method with the functions of sticking dust, flipping boards and coding. Four quadrants, the first quadrant and the fourth quadrant are the detection position, the second quadrant and the third quadrant are the feeding level, there is a discharge level between the detection position of the first quadrant and the feeding level of the second quadrant, and the fourth quadrant A discharge position is provided between the detection position of the third quadrant and the feeding position of the third quadrant, and a sticky dust coding mechanism is set between the two feeding positions. The unpowered roller group located on the side of the automatic transmission roller group away from the sticky dust coding mechanism. The detection position includes the detection table and the turnover mechanism located on the side of the detection desktop away from the manipulator. The turnover mechanism includes a rotating shaft and is driven by the rotating shaft. The flip-side suction cup assembly, one retractable trigger can be connected to two AOI equipment, with high work efficiency; it can accurately distinguish problem boards.

Description

technical field [0001] The invention relates to the technical field, in particular to an AOI board retractor and a board retractor method with functions of sticking dust, flipping and coding. Background technique [0002] AOI automatic optical inspection is a device that detects common defects encountered in welding production based on optical principles. The current AOI is mostly used for the detection of PCB boards and other fields, and it is necessary to perform front and back inspections on each board separately. During the detection process, the board is mostly retracted manually, the retraction speed is slow, and the board to be tested is held manually. Each time the board is taken and held in different positions, it is easy to cause board surface pollution, and often due to the influence of the operator, the detection misjudgment occurs. , The defective board is difficult to distinguish and so on. SUMMARY OF THE INVENTION [0003] Aiming at the shortcomings of the...

AI Technical Summary

Problems solved by technology

During the detection process, the board is mostly retracted and unwound manually, the speed of retracting and unwinding is slow, and the board to be tested is manually held, and the holding position of the board is different each time, which is easy to cause contamination of the board surface, and often leads to detection misjudgment due to the influence of the operator , Defective boards are difficult to distinguish, etc.
