The BBA Screw Fastening Machine for M3–M6 screws integrates error detection, tailored for smart device assembly. It guarantees accurate fastening, identifies installation anomalies in real-time, and optimizes efficiency in precision manufacturing lines.
The machine consists of:
– A working table.
– A fixed frame/
– Two sliding platforms, each with a holder (fixture)
for workpieces. These platforms can move back and
forward along Y axis.
– 1 servomotor screw driver, which rotate screw
driver bits and can move right and left along the X
axis.
– 1 screw driver bit, which can move up and down
along the Z axis, rotating at the same time.
– Motion devices, which can drive the abovementioned parts along X/Y/Z axis.
– An automatic screw feed device.
– Data input sensors.
– A control system.
– A handheld programmer console.
