6. Recognition unit
This machine uses a fiducial camera to recognize marks and a multi-camera, a scan camera and a side-view
camera to recognize components as the recognition units.

Fiducial cameras
HM head unit and FM head unit are equipped with this camera at side. This is used to recognize fiducial marks and bad
marks on boards and to perform teaching for components mounting position. The head unit has two fiducial cameras at
both sides as standard in order to extend the sight.
n
Scan camera
HM head unit is equipped with this camera at bottom. After components are picked up, this camera moves left and right
to recognize the picked component while the head unit moves to the mounting position. This has also the side-view
function as standard.
n
Side-view camera
FM head unit is equipped with this camera at bottom. This camera recognizes the pickup status by viewing horizontally.
This is a fixed camera to recognize component individually on each head.

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.

NOTE
For details regarding the side-view function's parameters, refer to the Programming Manual.
