Description
Technical field
The present invention relates to AOI detection technique field more particularly to a kind of AOI camera and light source module groups.
Background technique
The full name of AOI (Automatic Optic Inspection) is automatic optics inspection, be based on optical principle come
The equipment that the common deficiency encountered in welding production is detected.AOI is a kind of novel test technology newly risen, and is developed fast
Speed, many producers are all proposed AOI test equipment.Upon automatic detection, machine is adopted by camera automatically scanning product to be measured
Collect image, the solder joint of test is compared with the qualified parameter in database, by image procossing, detects product to be measured
Defect, and defect is shown by display or Automatic Logos, it is repaired for maintenance personal.
The equipment that AOI needs has camera and light source, and light source provides light, AOI in the prior art, camera for camera shooting
It is usually vertically arranged, the lower section of camera is arranged light source module group, and when shooting, the optical axis of camera mutually hangs down with the face that is taken of wiring board
Directly.Based on the irreflexive principle of light, PCB surface is incomplete plane, as shown in Figure 1, due to irreflexive presence, phase
Machine vertically shoots photo and forms a bright one dark light and shade striped, and the shooting photo of line scan camera and area array cameras occurs
The phenomenon of light and shade unevenness, effect of taking pictures as shown in Fig. 2, and photo light and shade unevenness then influence the binaryzation in image procossing misjudgement,
Software is directly affected to the judgement of wiring board shooting photo, the phenomenon of detection inaccuracy occurs.When camera is vertically shot,
Even if cooperating multi-angle light source, the appearance light and shade uneven phenomenon being still difficult to avoid that, even if being due to light source and vertical direction angle
It is small again, reflection light be also difficult to it is parallel with camera optical axis, shooting photo it is still undesirable.
Summary of the invention
It is an object of the invention to propose a kind of AOI camera and light source module group, have the characteristics that improve AOI detection accuracy.
