Vision Type 241 Insertion pin inspection
Vision Type 242 Insertion pin inspection
Vision Type 243 Insertion pin inspection
This vision type uses only the “sidelight” lighting pattern.
Vision type 241 determines positioning based on the shape of the part, and then checks for
bending of the pins. Vision type 242 estimates positioning based on the shape of the part,
and the makes a final determination of positioning based on the pins. Vision type 243
checks for bending of the pins, and then determines positioning based on the pins.
Body size and element information should be entered in shape data. It is also necessary to
enter radical data for vision type 241 and 242.
Vision Type 251 Segmented parts inspection
This vision type is different from vision type 252, and should be used for rectangular parts
whose body is divided into several different sections. Body size, body tolerance, and body
color should be entered in shape data.
Note: Refer to vision type 60 for rectangular chips.
Vision Type 252 Bodied parts inspection
This vision type is used for those parts with a white or gold colored body, and processes
only the part outline.
It is necessary to enter the body size in part data. The body size should be measured from
edge to edge. Positioning is performed using the outer-most points on the upper and lower,
and left and right part edges.
