Unit names and functions
6.2 Side-view function (Scan camera / Side-view camera)
The functions below can be used by Side-view camera and Scan camera to recognize components and nozzles
horizontally.
n
Pickup error detection function
Simple mode
Detects component pickup errors, thus preventing missed mountings.
Operation can continue without interruption even when nozzles are changed due to nozzle washing, etc.
Detailed mode
Detects component pickup errors, thus preventing missed mountings.
Vertical, horizontal, slanting, etc., pickup error judgments are made based on the user-specified component thickness
tolerance.
n
Soiled nozzle detection function
If a component is recognized as "present" at component recognition, but as "absent" by the side-view function, this is
judged a "soiled nozzle" condition, and a warning message displays.
This enables the user to better identify the best time to wash a nozzle.
n
Component discard operation skip function
A discard operation skip occurs if the side-view function makes a "component absent" judgment.
This reduces wasted operation when a component has not been picked up, resulting in a lower tact.
n
Component return detection function
Detects a component which is still on the nozzle tip after it should have been mounted or discarded.
n
Upside down check function
Checks (at recognition processing) for components which have been picked up in an upside down posture. This function
also checks to see if the picked-up component size can be contained within side-view camera's field of view.
An error message displays if the component is recognized as being upside down, or if its size cannot be contained within
side-view camera's field of view.
This function does not apply to components which have upper-half leads or for components which have no side-face
leads.
n
NOTE
For details regarding the side-view function's parameters, refer to the Programming Manual.

Multi-view cameras
The multi-camera recognizes components when the components are mounted with a FM head unit or when the
components, which are too big for a scan camera to recognize, are mounted with a HM head unit. This is installed on
either or both of front and rear depending on the machine layout such as the head unit selection. To recognize the
components with "Side lighting" setting such as BGA and flip chips, the components are lighted by the peripheral section
of this camera rising up.
n
NOTE
The maximum sizes of components that scan camera can recognize are as below.
YSM20R TypePV : 12 mm square , 6.5 mm height
YSM20R TypeSV : 8 mm square , 6.5 mm height
YSM20WR : 12 mm square , 6.5 mm height
n
NOTE
See the “Programming Manual” for the setting details of the side lighting.
