Fig. 1.12 - 2 Structure of the X axis
The x axis essentially consists of the following main modules: 1
– Gantry arm (1)
– Head mount (2)
– X axis measuring system (3)
– X axis guide system (4)
– X axis DC servomotor
– Toothed belt (6)
1
The head mount holds the following components: 1
– Sub-gantry camera (camera for the PCB vision module)
– Head board
– Measuring head for the x axis measuring system
– Revolver head

1.12.3 Technical data of the X axis
1.12.4 Structure of the Y axis
The y axis essentially consists of the following main modules: 1
– DC servomotor
– Y axis toothed belt
– Y axis guide system
– Y axis measuring system
1
Each y axis is driven by a three-phase AC servomotor. An anti-crash circuit prevents the paths of
the gantries meeting. 1
