Double-sided AOI ultrathin track

Abstract

The invention relates to the field of jigs, and discloses a double-sided AOI ultrathin track, which comprises a fixed side track, a movable side track, an upper illumination image capturing module with a lens, a lower illumination image capturing module with a lens and a to-be-tested board, wherein the fixed side track and the movable side track are oppositely arranged, a to-be-tested plate is located between the fixed side track and the movable side track and can move along the direction of the fixed side track, the upper illumination image capturing module is fixed on the movable side track,a lens of the upper illumination image capturing module is downward, and the lower illumination image capturing module is fixed on the fixed side track, and the lens of the lower illumination image capturing module is upward. The invention has the beneficial effects that: 1, the belt type design is adopted, the structure is simple, the processing and the assembly are convenient, and the cost is low; 2, an ultra-thin track is adopted, so that shading of the upper and lower image capturing modules is not influenced, and the type of a PCB is far superior to that of other machines.

Description

technical field [0001] The invention relates to the technical field of electronic manufacturing, in particular to a double-sided AOI ultra-thin track. Background technique [0002] With the development of integrated circuit technology, double-sided circuit boards are becoming more and more common. The front and back sides of the board are mounted or inserted with components. It is necessary to use AOI equipment to detect both the front and back sides of the circuit board, so double-sided AOI came into being. pregnancy. AOI equipment refers to AOI optical automatic detection equipment. Generally, the AOI imaging module is composed of a camera, a lens, and a light source. Since the upper and lower ends of the double-sided AOI need to be photographed and captured, on the track of the stop plate, the upper and lower sides cannot be blocked. Once it is blocked, the light source cannot enter, the imaging result is poor, and the test effect is naturally not good. So the design o...

Problems solved by technology

[0004] It can be seen that the existing chain-type track is bulky, takes up space, and blocks light from the upper and lower imaging systems, and the test effect is poor; For some PCB boards; and the cost of the two existing tracks is slightly higher, and the structure is complex, and the economic benefits are not obvious
