Q
How does the automatic lock screw machine detect floating locks, sliding teeth and missing nails?
A
We all know that the automatic locking screw machine is used to replace the manual screwing automation equipment, but often encounters the leakage lock (no screw) and the sliding tooth during the screwing process (between the electric screwdriver and the screw head) How to detect this situation when the automatic screwing machine is used when the slipping) and the floating lock (the screw is not screwed to the bottom)?

The missing nails are generally not sent by screws. The screws are mainly screw feeders. The screws are sorted and sent to the feeding pipeline. The sensor is installed at the feeding pipeline. A screw sensor is sent to detect a pulse signal to the PLC. After the system receives the signal, the PLC control system will blow and lock the screw. If there is no screw to be sent, there will be a patching action. If the nail is not sent normally, the device will stop and alarm, waiting for the fault. exclude.

Sliding teeth and sliding head detection principle: the automatic locking screw machine will set the torque and torque parameters of the lock before the lock is paid. When the electric screwdriver normally locks the screw, after the set torque is reached, the electric batch will automatically cut off the electric brake. At the same time, the pulse signal is sent to the PLC control system; when the sliding tooth or the sliding head occurs, the set torque is not reached when the electric batch lock is paid, the electric batch will not stop running, so there is no signal to the PLC, and the PLC passes the operation. It is possible to determine if the screw is slippery or slippery.
