Detailed analysis of the principle of automatic screw machine: When the automatic screw machine releases the locking screw data signal, the feed machine magnetic induction system software signal receiver pushes the command to the feed controller, thus starting the feed controller hopper of the screw belt conveyor, according to the standard screw of the three-phase five-wire detector (automatic filter reverse screw), The key to the automatic screw conveying equipment is to transport the entire single screw to the non-cylinder clamp of the screw tightening equipment, the standard air pressure will enter the screw from the screw tube, wait for the lock payment, the lock payment is complete, the screw conveyor controller sends the data signal to the signal receiver, automatically predicts to the screw lathe tray, wait for the next lock screw data signal. The locking payment institution checks the status of the locked payment throughout the locking process OK.
According to various electric air blowing methods, the automatic screw machine maintains the automatic screw pinning, tightening and detection, simplifies the entire tightening process according to the mechanical equipment, reduces the actual manual operation frequency, and reduces the adverse factors caused by manual wrong operation. This is a typical non-standard automatic mechanical equipment.
First, automatic feeding machine
In terms of selection, sequencing, detection, detection range, transportation, etc., the key bearing screw of the automatic screw feeder is a key step to replace the manual screw.
According to the feeding method can be divided into blow suction type and adsorption type.
Blower type: Blower type feeding is a feeding equipment equipped with a basic automatic screw tightening machine. Select a blower feeder to select, sort and test screws. According to the standard air pressure, the screw is automatically transferred to the lower part of the locking mechanism, waiting for locking. Mechanical device screws are the same as feed screws and do not close.
Adsorption type: The adsorption type feeder is more common in the coordinate mechanical equipment feeder, which is a good practical feeder method. Screw transport, inspection and cutting are carried out by screw feeders. The coordinate machine pushes the screw back and forth and then tightens the whole process. The advantage is that it is not affected by screw size.
Second, the lock payment mechanism
The lock payment mechanism (known as the lock payment touch group in the manufacturing industry) is configured in strict accordance with the Settings of the mass, air blown mass or AC servo motor to achieve tightening posture, completely replacing the manual actual operation.
According to the different locking mechanism, it can be divided into electric batches, air blast batches, servo motor drivers and so on. The torque is very high; It can be locked according to the given servo motor torque value, with higher accuracy and quite fast speed.
Three, power box
The key to the automatic control system is located in the 220V electrical equipment box. PLC(or single-chip microcomputer design) operation, to maintain the coordination of automatic feeding and locking mechanism, to achieve the actual effect of automatic locking.
Fourth, mobile phone positioning system
The key to the mobile phone positioning system (motion touch group) is to ensure that the locking mechanism can accurately rotate the screw into the wire hole part of the product. Accurate positioning is carried out by the console, tool fixture, tool fixture and other accessories. Generally speaking, the design scheme must be carried out according to the appearance characteristics of the product.
