Referring to fig. 7, the method for pressing a line of an automatic line pressing device based on an optical communication conductive ring includes:

s100, placing the conducting ring and the wire, and when the automatic wire pressing device is started, judging whether the wire is placed in place or not by the detection assembly and outputting a corresponding wire detection signal to the control assembly.

In this step, a worker places the conductive ring 14 in the wire pressing groove of the conductive ring placement base 13, and inserts the wire 15 into the wire pressing hole of the conductive ring. So that the wire 15 is located just in front of the proximity sensor 16. When the programmable logic controller 8 detects that the start button 302 on the main panel 3 is pressed, the automatic line pressing device is started to execute the pre-stored line pressing program. The proximity sensor 16 outputs a wire detection signal of a corresponding level (e.g., high level) to the programmable logic controller 8 when detecting that there is an object (i.e., the wire 15) in front of the proximity sensor, and the proximity sensor 16 outputs a wire detection signal of a corresponding level (e.g., low level) to the programmable logic controller 8 when the wire 15 is tilted and is not detected.

And S200, the control assembly carries out alarm prompt when judging that the wire rod is not in place according to the wire rod detection signal, and controls the working state of the pneumatic wire pressing assembly according to the operation of a key on the control box when judging that the wire rod is in place.

If the programmable logic controller 8 recognizes that the wire 15 is not in place, the indicator lamp 301 can be lighted to give an alarm, and after the worker checks and replays the wire, the worker needs to press the reset button 304 to enable the double-power cylinder to return to the original position and restart (press the start button again).

S300, when the pneumatic wire pressing assembly is in a wire pressing state, the wire is tightly connected with the conductive ring and is detected whether to be tightly pressed in place, and a corresponding pressing detection signal is output to the control assembly; and the control component carries out alarm prompt when judging that the pressing is not in place according to the pressing detection signal.

In this step, the programmable logic controller 8 opens the two-position three-way solenoid valve 6 according to the wire pressing program, the two-position three-way solenoid valve 6 controls the double-force cylinder 11 to advance, so as to drive the extrusion punch 12 to move towards the conducting ring placing base 13 until 2 protrusions of the extrusion punch 12 are correspondingly inserted into 2 recesses on the side surface of the conducting ring placing base 13, the punch 121 extrudes the conducting ring 14 to enable the conducting ring to be plastically deformed, and the wire 15 can be connected with the conducting ring in a pressing manner. The programmable logic controller 8 detects whether the magnetic switch 10 outputs a compaction detection signal, if the line pressing distance meets the requirement (i.e. the moving distance of the extrusion punch 12 meets the requirement), the magnetic switch 10 outputs a compaction detection signal of a corresponding level (such as a high level) to the programmable logic controller 8, and if the distance is not enough to compact, the magnetic switch 10 does not output the compaction detection signal or the compaction detection signal is a low level. And when the programmable logic controller 8 detects a high-level compression detection signal, the wire pressing is judged to be successful, the two-position three-way electromagnetic valve 6 is closed to enable the double-force cylinder 11 to return to the original position, and at the moment, a worker can take out the wire pressing conducting ring to finish the wire pressing operation. If a low-level compaction detection signal is detected or the compaction detection signal is not received, the wire pressing is judged to be failed, the programmable logic controller 8 lights the indicator lamp 301 to give an alarm prompt, and after a worker checks and replays the wire, the reset button 304 needs to be pressed, so that the double-force cylinder returns to the original position and starts again (the start button is pressed again).

In summary, the automatic wire pressing device based on the optical communication conducting ring provided by the invention adopts a Programmable Logic Controller (PLC) to perform core control, and opens a two-position three-way electromagnetic valve when a wire is detected to be in place, and controls a multiplying cylinder to advance so as to extrude a punch to perform wire pressing operation. The double-force cylinder can guarantee to output sufficient pressure as power executive component, whether detect through proximity sensor before the execution compresses tightly the action correctly places the wire rod, whether the magnetic switch who combines double-force cylinder department detects the double-force cylinder and puts in place when advancing, can guarantee that conducting ring and wire rod compress tightly completely, has improved the precision of line ball, the instability when avoiding manual operation to it is more convenient to make the line ball process, and the line ball quality is more reliable. The wire rod is not correctly placed or does not meet the pressing requirement, brightness warning is carried out, manual intervention is reminded, and timely error correction and self-checking of workers are facilitated.

The division of the functional modules is only used for illustration, and in practical applications, the functions may be distributed by different functional modules according to needs, that is, the functions may be divided into different functional modules to complete all or part of the functions described above.

It should be understood that equivalents and modifications of the technical solution and inventive concept thereof may occur to those skilled in the art, and all such modifications and alterations should fall within the scope of the appended claims.
