Eli phepha liya kwazisa umgaqo wokusika kwe-ultrasonic, kwaye udibanise imizekelo yeemveliso ezithile ze-elektroniki ukuthelekisa iziphumo zokusika ngomatshini kunye nokusika i-laser, kwaye ufunde ngokusebenza kwetekhnoloji yokusika ye-ultrasonic.

· Intshayelelo

Ukusika i-Ultrasonic yitekhnoloji ephezulu yokucheba iimveliso ze-thermoplastic. Itekhnoloji yokusika ye-Ultrasonic isebenzisa i-ultrasonic welding ukusika imisebenzi. Izixhobo ze-ultrasonic welding kunye nezixhobo zayo nazo zifanelekile kwiindawo zokuvelisa ngokuzenzekelayo. Itekhnoloji yokusika ye-Ultrasonic isetyenziswa ngokubanzi kurhwebo nakubathengi beelektroniki, izithuthi, amandla amatsha, ukupakisha, unyango, ukulungisa ukutya kunye nezinye iinkalo. Ngophuhliso olukhawulezileyo loqoqosho lwasekhaya, uluhlu lwezicelo luya kuba banzi kwaye lubanzi, kwaye ibango kwintengiso liza kukhula ngakumbi. Ke ngoko, itekhnoloji yokusika ye-ultrasonic inethemba elikhulu lophuhliso.

· Ukusika ngoomatshini

Ukusika ngomatshini ukwahlulwa kwezinto ngeendlela zoomatshini kwiqondo lobushushu eliqhelekileyo, njengokucheba, ukusarha (isarha yesarha, isarha yomsila, isarha yesanti, njlnjl.), Ukugaya njalo njalo. Ukusika ngoomatshini yindlela eqhelekileyo yokwenza izinto ezirhabaxa kunye nokusika okubandayo. Umongo kukuba izinto eziza kusetyenzwa zifakwa kwisikere ukuze kwenziwe i-shear deformation kunye nokunciphisa inkqubo yokwahlukana. Inkqubo yokusika ngoomatshini inokwahlulahlulwa ngokwezigaba ezithathu ezilandelelanayo: 1. isigaba sokumka kwe-elastic; 2. Inqanaba lokumila kweplastiki; 3. isigaba sokuqhekeka

· Laser ukusika

3.1 Umgaqo wokusika i-laser

Ukusika i-Laser kusebenzisa ukukhanya kwe-laser ene-high-power-density ukukhanyisa indawo yokusebenza, ukufudumeza izinto ukuya kumawaka ukuya kumawaka ama-degrees Celsius ngexesha elifutshane kakhulu, ukuvumela ukuba imathiriyeli inyanzeliswe ukuba inyibilike ngokukhawuleza, yenze umphunga, ityebe, okanye ilume, Ngelixa usebenzisa umqadi Ukuhamba ngesantya esiphezulu kwe-coaxial kuvuthuza izinto ezinyibilikisiweyo, okanye izinto ezinomphunga ziphephetheka kude nesikwere, ngaloo ndlela zisika indawo yokusebenza ukuze zifezekise injongo yokusika umbandela. Laser ukusika yenye yeendlela ukusika eshushu.

3.2 Iimpawu zokusika zeLaser:

Njengendlela entsha yokuqhubekeka, ukusetyenziswa kwe-laser kusetyenziswe ngokubanzi kumzi mveliso we-elektroniki ngenxa yokulunga kwayo ngokuchanekileyo, ngokukhawuleza, ukusebenza ngokulula kunye neqondo eliphezulu lokuzenzekelayo. Xa kuthelekiswa nendlela yokusika yemveli, umatshini wokusika we-laser awusezantsi nje kwixabiso, asezantsi ekusebenziseni, kwaye ngenxa yokuba ukusetyenziswa kwe-laser akukho xinzelelo loomatshini kwindawo yokusebenza, isiphumo sokusika imveliso, ukuchaneka kunye nesantya sokusika kakhulu Kulungile, kwaye ukusebenza kukhuselekile kwaye ukugcinwa kulula. Iimpawu ezinje ngokuma kwemveliso esikwe ngumatshini we-laser ayityheli, umda ozenzekelayo awukhululekanga, akukho deformation, akukho nzima, ubungakanani buhambelana kwaye buchanekile; unokusika nayiphi na imilo entsonkothileyo; ukusebenza kakuhle, ngexabiso eliphantsi, uyilo lwekhompyuter inokuyisika nayiphi na intambo yesayizi nangayiphi na indlela. Ukuphuhliswa okukhawulezayo: Ngenxa yokudityaniswa kwetekhnoloji ye-laser kunye nekhompyuter, abasebenzisi banokuyila imveliso yokukrola ye-laser kwaye batshintshe ukukrola nangaliphi na ixesha okoko zenzelwe ikhompyuter. Ukusika i-Laser, kuba umqadi ongabonakaliyo uthatha indawo yemela yemveli, inxenye yentloko ye-laser ayinanxibelelwano nomsebenzi, kwaye ayizukukrwela umphezulu osebenzayo ngexesha lomsebenzi; isantya sokusika i-laser siyakhawuleza, ukusikwa kugudile kwaye kucaba, ngokubanzi akukho mfuneko yokuqhubekeka emva koko; akukho xinzelelo loomatshini xa kusikwa, akukho burr shear; ukusebenza ngokuchanekileyo okuphezulu, ukuphindaphinda okuhle, akukho monakalo kumphezulu wezinto ezibonakalayo; Inkqubo ye-NC, inokuqhubekeka nasiphi na isicwangciso, inokulisika ipleyiti yonke ngefomathi enkulu, akukho mfuneko yokuvula ukungunda, ukonga ixesha lokugcina.

Ukusika kwe-Ultrasonic

4.1 Umgaqo wokusika we-Ultrasonic:

Ngoyilo olukhethekileyo lwentloko ye-welding kunye nesiseko, intloko ye-welding icinezelwe emaphethelweni emveliso yeplastiki, kwaye ukungcangcazela kwe-ultrasonic kusetyenziselwa ukusika imveliso ukufezekisa isiphumo sokusetyenziswa ngokusebenzisa umgaqo wokusebenza wokungcangcazela we-ultrasonic. Njengakwindlela yokulungisa yemveli, umgaqo osisiseko wetekhnoloji yokusika ye-ultrasonic kukusebenzisa umbane we-elektroniki we-elektroniki ukuvelisa amaza e-ultrasonic ohlobo oluthile lokuhamba, kwaye ke ubukhulu bokuqala kunye namandla zincinci zitshintshi ze-ultrasonic-mechanical ezibekwe kwi-ultrasonic ukusika intloko. Ukungcangcazela kwe-ultrasonic kuguqulwa kube kukungcangcazela koomatshini bexesha elifanayo, emva koko kwandiswe ngesandi ukufumana ubukhulu obaneleyo kunye namandla (amandla) ukuhlangabezana neemfuno zokusika indawo yokusebenza. Okokugqibela, amandla adluliselwa entlokweni ye-welding, emva koko imveliso iyanqunyulwa. Izibonelelo zokuqhekeka zigudile kwaye azikhe ziqhekeke.
Inkqubo yokushukuma kwe-Ultrasonic ubukhulu becala yenziwe nge-ultrasonic transducer, uphondo lwe-ultrasonic kunye nentloko ye-welding. Phakathi kwabo, umsebenzi we-ultrasonic transducer ukuguqula isignali yombane ibe ngumqondiso we-acoustic; uphondo luyinxalenye ebalulekileyo yezixhobo zokwenza i-ultrasonic. Inemisebenzi emibini ephambili: (1) ukuxinisa amandla-oko kukuthi, ukufuduka kwento eshukumayo okanye isantya samandla sonyuselwe, okanye amandla agxile kumhlaba omncinci wemitha yokuqokelela amandla; (2) amandla e-acoustic adluliselwa ngokufanelekileyo kumthwalo- Njengokuguqulela i-impedance ngoomatshini, ukuhambelana kwe-impedance kwenziwa phakathi kwe-transducer kunye nomthwalo we-acoustic ukuvumela amandla e-ultrasonic ukuba adluliselwe ukusuka kwi-transducer ukuya kumthwalo ngokufanelekileyo.

4.2. Iimpawu zokusika kwe-ultrasonic:

Xa umbane we-ultrasonic wonwabile ukufikelela kubushushu obuphezulu, imveliso iyanyibilika ngenxa yokutsala okuphezulu kwe-intermolecular excitation kunye nokukhuhlana kwangaphakathi.

Iimpawu zokusika ze-Ultrasonic. Ukusikwa kwe-Ultrasonic kunezibonelelo zokusika okugudileyo kunye nokuqina, ukusika ngokuchanekileyo, akukho deformation, akukho warping, fluffing, spinning, wrinkling njalo njalo. "Umatshini wokusika we-laser" onokuthintelwa unezinto ezingeloncedo ngokusika irhabaxa, i-focal edge, ipilisi, njl. Izinto eziluncedo zokusika i-ultrasonic zibandakanya: 1. Isantya sokubaleka ngokukhawuleza, kunye nexesha eliqhelekileyo lokujikeleza elingaphantsi komzuzwana omnye. 2. Amalungu eplastiki akanaxinzelelo; 3. Umphezulu wokusika ucocekile; Iindawo ezininzi zinokunqunyulwa ngexesha elinye lokwahlukana ngokuzenzekelayo 5 Ukusika i-ultrasonic ayisiyongcolisi.

Luhlobo luni lwezinto ezisetyenziswayo kusetyenziswa i-ultrasound? Owona msebenzi ulungileyo kwi-thermoplastics engqongqo (polycarbonate, polystyrene, ABS, polypropylene, nylon, njl. Badlula amandla oomatshini ngokufanelekileyo. Ukuqina okungaphantsi (imodyuli yokuqina) i-thermoplastics enjenge-polyethylene kunye ne-polypropylene ifunxa amandla oomatshini kwaye inokunika iziphumo ezingahambelaniyo.

· Isiphelo

Xa kuthelekiswa nemiphumo yokusika ngomatshini, ukusika i-laser kunye nokusika kwe-ultrasonic, i-ultrasonic ikulungele ngakumbi ukusika indlebe yemveliso, kwaye isiphumo silungile, ukuhlangabezana neemfuno zokusika kwemveliso, kunye nokusebenza kokucheba kwe-ultrasonic lelona liphezulu. Ukusikwa kwe-Ultrasonic sisisombululo esifanelekileyo kwiimfuno zokusika kwemveliso.

Ngokuqhubeka kancinci kophando kwitekhnoloji yokusika ye-ultrasonic, kukholelwa ukuba kungekudala, iya kusetyenziswa ngokupheleleyo.
