Summary: Positional sensor is automation is assembled, detect, solder, the crucial part in the private plane such as treatment, once be measured by accident, light bring about what work automatically to interrupt, cause the damage of mechanical spare parts again. The article places bolt to send the position in locking up device automatically the analysis of sensor occurrence breakdown through lead, get those who give sensor of the position in automation private plane to decorate should abide by: The principle of substantivity, stability and static state, positional sensor is decorated correctly conduce to private plane moving automatically reliably. 0 foreword are automatic private plane position detects pass feeling component to be used mostly be close to sensor, it is a kind of object to be close to it has " feel " the parts of an apparatus of ability, it is to make sure the spare parts is transmitted by the move that expects set, treatment, assemble, detect, soldering crucial part, the peripheral that the PLC in private plane gives out executes behavioral signal, rely on positional sensor mostly spark signal, once positional sensor false triggering, light bring about what work automatically to interrupt, cause the damage of mechanical spare parts again. The sensor of cloth set buy of 1 position sensor is decorated in automatic private plane when, must consider the requirement of substantivity, stability and static state. 1.

1 substantivity substantivity is positional sensor must set the ultimate position that transmits some movement way to go up in workpiece, the setting of any intermediate positions, will cause athletic uncertainty. Illustrate, graph 1 send a lock automatically plant construction sketch map for lead clip bolt, graph 2 for lead clip bolt sets a plan. Its start course is such: Lead is placed by vibration dish after 1 sort is transmitted, fall into index plate in the fixed position aperture of 3, break up implement 2 drive index plate 3 had turned an angle, lead clip sends to clamp 4 bottom, air cylinder 6 be issued to lower levels, drive screwdriver 5 edges are sharp slideway 7 move point-blank downward, wait for after touching bolt, in twisting bolt lead to place, in the graph 8 for bolt vibration dish (omited bolt is oscillatory dish output mouth comes clamp the plastic pipe of 4) , after a bolt twists lead to place by screwdriver, air cylinder 6 drive screwdriver 5 go up, when screwdriver 5 retreat to initiative position hind, another bolt passes plastic pipe by inbreathe clamp 4 in, with time dial 3 had turned an angle, another lead clip is sent to clamp bottom needs combination, the lead clip of finished product falls into makings storehouse. Graph 3 place whereabouts to index plate for lead of aperture of 3 fixed position detect sensor location drawing, sensor the setting is in before slideway 10 on, in the process falling below electric clip, when slideway 10 when with index plate 3 aperture unfinished is aimed completely, lead places whereabouts to block sluggish phenomenon from time to tome, bring about electric clip to did not reach the designated position, but positional sensor already the induction sparks to the object signal, make break up implement 2 rotate, to lead clip undertakes cutting, spare parts of attaint private plane, bring about break up implement 2 in bearing by clipping, accordingly, sensor must install what place after all in lead locally, if pursue 3 in 11, after only lead clip reachs the designated position completely, sensor just can give out signal, break up implement 2 ability but drive index plate 3 roll. 1.

2 stability stability is sensor to must be being stabilized by the signal of inductive spare parts, cannot when do not have sometimes, this asks by inductive face it is enough as far as possible old plane, circular arc face shoulds not be inductive face, appear easily otherwise sensor sparks signal does not stabilize a phenomenon. Graph 4 for bolt vibration dish the transmission orbit of exit, when be being debugged first, sensor the setting is on lateral slideway, if pursue medium,13 are shown, can appear now and then sensor did not spark signal, bolt already bestrewed slideway, cannot cut the condition into deferent and plastic pipe however, investigate its reason is sensor to two bolt rear among, because be close to switch induction metal to certain distance asks (general and small-sized sensor is not more than 2mm) , when apropos when the intermediate position to two bolt rear, can appear sensor induction is less than bolt phenomenon, sensor the setting goes to transmission orbital upside after, if pursue medium,12 are shown, to induction of bolt rear plane, of sensor spark signal stability rises apparently. Notable is, when having indentation in the light of metallic induction face, appropriate is chosen a few bigger the positional sensor of norms, in order to reduce the indentation effect to inductive face. 1.

Static state of 3 static states asks positional sensor must be secured namely in relatively dormant or on the matrix that low speed moves, when the job, the sensor that is in violent campaign or oscillatory matrix to go up often appears phenomenon of signal false triggering. Graph installation of the 5 fiber sensor that it is light places vibration at lead dish on, basically be for divisional graph 6 lead place the condition of screw and flank asymmetry, as a result of fiber-optic sensor 15 installation Yu Zhen is moved dish 1 on, the sensor when the job and lead clip shake extent is abhorrent, sensor detects to lead clip appearance occurrence deviation, occurrence leakage touchs discovery to resemble, the lead clip that brings about different way was not distinguished to come out and blow a vibration dish, occurrence miscarriage lead places a phenomenon, will fiber-optic sensor sets park level to transmit slideway second half point-blank after paragraph on (before half Duan Yuzhen uses dish of connection, second half paragraph join with perpendicular transmission slideway, be in relatively static condition) , different way lead clip inbreathe stores box, the lead after making transmit places direction to agree entirely. Clip of lead of 2 actual application, bolt sends lock device automatically to be installed in all 7 is in positional sensor, it is respectively: A lead clip enters index plate office by slideway, detect whether does lead clip reach the designated position, break up in order to spark implement rotate; B clamp place of aperture of fixed position of clip of lower part lead, detect whether does lead clip reach the designated position, drive screwdriver be issued to lower levels in order to touch job of hair air cylinder; Bolt of C lead clip sets project below one labour, detect bolt, whether to succeed in order to judge combination; D bolt is oscillatory dish of exit, detect bolt, move in order to stop oscillatory Pan Zhen; E bolt is oscillatory dish of slideway extreme, detect bolt, with sparking oscillatory Pan Zhen is moved and bolt cuts plastic pipe air cylinder to work; Entrance of F plastic pipe is in, detect whether does bolt enter plastic pipe; G lead places linear transmission slideway to go up, those who identify lead clip is prejudicial, the lead of different way clip inbreathe stores box; What these positional sensor are controlling private plane is automatic move, because initial stage is right of sensor decorate devoid experience, unreasonable to setting of sensor of place of A, E, G, in bringing about lead clip and bolt to transmit a process automatically or occurrence card sluggish calls the police phenomenon, or appear to be not pressed book sort phenomenon, will break up even once implement the bolt clipping of 2 interior, the course presses afore-mentioned demands to sensor position after improve, lead is placed and transmit automatically of bolt gradually normal, the efficiency of private plane is shown gradually. Since lead clip bolt sends lock private plane automatically to be used through a year many, moving stability is reliable, achieve a design basically to expect an end. Sensor of 3 epilogue position is used extensively on automation private plane or automation automation line, cheap, function stabilizes the value, installation is debugged convenient, but when the position in setting sensor, must careful discretion, follow general pattern, the substantivity that narrates like article place, stability and static state ask, in order to obtain the signal with stable sensor. Automation develops personnel to should be main goal in order to go after automatic private plane or automation line dependability, although sensor installs the position to reach the designated position not completely, won't work to appear to be interrupted automatically every time or attaint of mechanical spare parts, but its fault rate is opposite taller it is inevitable, this is in a lot of circumstances are unallowed, hope broad technology personnel can be excelsior, raise the reliability that automatic private plane or automation line run automatically hard.
