The Automatic Screw Fastening System is engineered for home appliance assembly, focusing on M1–M3 screws. It enables accurate and rapid screw tightening, enhancing production efficiency while maintaining consistent fastening quality.
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.
