1.12.2 Structure of the x axis
1
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 three-phase AC servomotor (5)
– Toothed belt (6)
The head mount holds the following components 1
– sub-gantry camera (camera for the PCB vision system)
– head board
– measuring head for the x axis measuring system
– revolver placement head

1.12.3 Technical data for the x axis
1.12.4 Structure of the y axis
The y axis essentially consists of the following main modules: 1
– y axis three-phase AC 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 traversing
paths of the gantries meeting. 1
