4.1.4.3 Paste Roll Height Laser
The paste roll height laser measures the height of the paste roll in front of the front squeegee dur-
ing a rearward print stroke.
4.1.4.4 Coplanarity Lasers
There are two coplanarity lasers mounted on the print carriage. During coplanarity calibration, the
lasers measure the difference between the top of the transport conveyors and the stencil in four po-
sitions.
4.1.4.5 Temperature and Humidity Sensors
The temperature and humidity sensors are mounted on the back of the print carriage, monitoring
the print area. The results are displayed on the HMI monitor.
4.1.5 Camera System Module
The camera system module is used for the following functions:
●
Use visual information to align the stencil to the product board
●
Use visual information for board or stencil inspection
●
Provide visual information for the user on the HMI monitor
●
Stops the board in the correct position for printing
The camera traverses in the X direction within the camera carriage using a linear motor. The cam-
era carriage traverses in the Y direction using a linear motor on the Y drive. The Y drive is also
shared by the under stencil cleaner.
