IoT Screw Driver Measures Tightness of Screws


I want to keep a record of the work performed for tightening screws and prevent output of defective products. Additionally, improvements cannot happen without understanding the current situation with the variations in assembly work.


Connect the signal output of each electric screwdriver to the WD to quickly and easily build a system that is inexpensive.
・Automatically record the screw tightening value (with the increase torque signal)
・At each cell, automatically record the number of operations and the order for multiple screwdrivers (Electric screwdrivers are identified by registering their names with the WD transmitter's MAC address)
・Automatically record loosen screw operations (with the reverse and start signals)
・Compile all the electric screwdriver operations at the facility (with the WD unit's csv log file)
