Kushandiswa kweLaser Precision Spot Welding muIndasitiri yeElectrical yeVatengi
Mumakore achangopfuura, sezvo makwikwi mumusika wemagetsi evatengi akawedzera, vagadziri vezvigadzirwa zvemagetsi vakaisa zvinodiwa zvakanyanya kune zvigadzirwa. Nzira dzechinyakare dzekugadzirisa dzinowanzoita kuti mhando yezvigadzirwa isagadzikane, kunyunguduka kwechikamu, kuoma kugadzira ma weld nuggets akajairwa, uye mwero wegoho wakaderera. Kubuda kwetekinoroji yekugadzira laser kunogona kugadzirisa matambudziko aya nekukurumidza kune vagadziri vezvigadzirwa zvemagetsi. Mukugadzirwa kwezvigadzirwa zvemagetsi zvepamusoro, laser processing inoita basa rakakosha mukuvandudza huwandu hwezvigadzirwa uye kuvandudza mhando, zvichiita kuti zvigadzirwa zvive nyore, zvitete, uye zvakagadzikana. Zvinonzi tekinoroji ye laser (maitiro anopfuura makumi maviri akasiyana) uye michina yekugadzira ine chekuita nazvo inoshandiswa muinenge 70% yemagetsi ekugadzirisa zvigadzirwa uye magadzirirwo ezvigadzirwa.
Parizvino, welding yelaser chaiyo inoshandiswa zvakanyanya pamakeji ezvigadzirwa zvemagetsi, mavharo ekudzivirira, ma USB connectors, ma conductive patches, nezvimwewo. Ine zvakanakira zvakaita sekushanduka kwekushisa kudiki, kutonga kwakaringana kwenzvimbo yekushanda nenzvimbo, mhando yepamusoro yewelding, kugona kuwana welding yezvinhu zvakasiyana, uye nyore kushandisa otomatiki. Zvisinei, nzira dzakasiyana dzewelding dzinofanira kushandiswa pakuwelding zvinhu zvakasiyana.
Zvichibva pamhedzisiro yekuedza kwakawanda, mainjiniya ekubatanidza simbi vakapfupikisa zvakanakisawelding yemavara e laser chaiyonzira dzekushandisa zvinhu zvakasiyana-siyana zvakaita sezvinhu zvinopenya zvakanyanya, machira matete esimbi, nezvimwe zvinhu zvakasiyana mukugadzirwa nekugadzirwa kwemagetsi evatengi.
1. Nzira yeLaser Precision Spot Welding yezvinhu zvinopenya zvakanyanya
Pakusunga zvinhu zvinopenya zvakanyanya zvakaita searuminiyamu nemhangura, mafungu akasiyana ewelding ane simba guru pamhando yewelding. Kushandisa laser waveform ine pre-spike kunogona kupwanya high reflectivity barrier. Simba repamusoro-soro rinogona kuchinja nekukurumidza mamiriro esimbi, richikwidza tembiricha yayo kusvika pakunyunguduka, nokudaro richideredza reflectivity yesimbi uye richivandudza kushandiswa kwesimba. Pamusoro pezvo, nekuda kwekukurumidza kupisa kwezvinhu zvakaita semhangura nearuminiyamu, kushandisa waveform inoora zvishoma nezvishoma kunogona kugadzirisa chitarisiko chenzvimbo dzeweld.
Kune rumwe rutivi, mwero wekunyudzwa kwelaser kwezvinhu zvakaita segoridhe, sirivha, mhangura, uye simbi unoderera sezvo wavelength ichiwedzera. Kune mhangura, kana wavelength yelaser iri 532nm, mwero wekunyudzwa kwemhangura uri pedyo ne40%. Kuongorora kwakaenzaniswa kwehunhu hwe infrared lasers nema green lasers kunoratidza kuti infrared lasers dzine saizi yakakura yenzvimbo, kudzika kwefocal kupfupi, uye mwero wakaderera wekunyudzwa nemhangura tsvuku; ma green lasers ane saizi diki yenzvimbo, kudzika kwefocal kurefu, uye mwero wakakwira wekunyudzwa nemhangura tsvuku. Kana pulse spot welding ichiitwa pamhangura tsvuku uchishandisa ma infrared lasers nema green lasers zvakateerana, zvinowanikwa kuti saizi yenzvimbo dzekuwelda mushure mekuweldane infrared lasers hazvienderane, nepo mavanga ekuweld anoumbwa ne green lasers akafanana muhukuru, anowirirana muhupamhi, uye akatsetseka pamusoro (Mifananidzo 1-2). Welding ne green lasers inowana mhedzisiro yakagadzikana, uye simba repamusoro rinodiwa rakaderera kupfuura hafu pane re infrared lasers.
2. Nzira yeLaser Precision Spot Welding yeZvishandiso zveMapepa Matete eSimbi
Kana ma-millisecond laser echinyakare achishandiswa kusanganisa zvinhu zvesimbi zvakatetepa, zvinhu zvacho zvinopinda nyore nyore uye nzvimbo dzekutsvedza dzakakura. Nekuda kwekusagadzikana kwazvo uye mwero wakaderera wekunyudzwa kwelaser muchimiro chakasimba, zvinhu zvinopenya zvakanyanya zvinowanzosangana nekupararira, kusakwana kwewelding, nezvimwe zviitiko panguva yekutsvedza. Kugadzirisa matambudziko ekutsvedza emashizha matete nesimbi dzinopenya zvakanyanya, analog nedigital modulation zvinoitwa nenzira yakateerana paQCW/CW mode yefiber lasers. Chinhu chimwe chete chinogona kuburitsa N pulse outputs, zvichiita single-point.welding yekurova kwemoyo yakawandanesimba rakaderera.
3. Nzira yeLaser Precision Spot Welding yeZvinhu Zvakasiyana
Kana zvinhu zvitete zvakasiyana ne laser zvichishandiswa, matambudziko akadai sekushaya kukwana kwe welding, kutsemuka, uye simba shoma remajoini anogona kuitika. Izvi zvinodaro nekuti zvinhu zviviri izvi zvine musiyano mukuru muhunhu hwepanyama, kushoma kwekunyungudika, uye zvinowanzoita kuti pave ne brittle intermetallic compounds, izvo zvinoderedza zvakanyanya hunhu hwe mechanical hwe welded joint. Kushandisa nanosecond laser ine high beam quality kuburikidza ne high-speed scanning kunogona kudzora kupisa kuti kudzivirire kuumbwa kwe intermetallic compounds, kuona lap welding yesimbi dzakatetepa dzakasiyana, uye kuvandudza weld formation uye hunhu hwe mechanical.
Mhando Dzakajairika dzeKushongedza Nekushongedza Zvakanyanya
Ndedzipi mhando dzakajairika dzekugadzirisa nekushandisa simbi zvine hungwaru? Mubasa rekugadzirisa nesimbi zvine hungwaru, mhando dzakajairika dzekugadzirisa nesimbi zvine hungwaru dzinosanganisira simbi dzine hungwaru hwekudzivirira simbi zvine hungwaru, simbi dzine hungwaru hwelaser, simbi dzine hungwaru hwe ultrasonic, uye simbi dzine madonhwe e micro arc. Nekuda kwehunhu hwakasiyana hwema laser, zvichienzaniswa nedzimwe nzira dzekugadzirisa nesimbi, simbi dzine hungwaru hwekushandisa nesimbi zvine hungwaru hwepamusoro, hushamwari kune nharaunda, uye hungwaru hwekugadzirisa nesimbi zvine hungwaru.
Mashandisirwo Akakosha eLaser Precision Spot Welding
Kupinza nzvimbo ye laser kwakanyatsoshandiswa kupi? Parizvino, kupinza nzvimbo ye laser kwakanyatsoshandiswa kunogona kushandiswa pakupinza zvinhu zvidiki zvakasiyana-siyana zvinonzwa kupisa zvakaita sezvishongo, magirazi ebvudzi, uye matambo emagetsi akabatanidzwa. Yakakodzera maindasitiri akadai semidziyo ye optoelectronic, zvemagetsi, zvekutaurirana, michina, mota, indasitiri yemauto, uye zvishongo zvegoridhe. Semhando yekubatanidza ne laser, kupinza nzvimbo ye laser kwakanyatsoshandiswa inzira itsva yekupinza. Kana ichienzaniswa nekupinza nzvimbo ye resistance, kupinza nzvimbo ye laser kwakanyatsoshandiswa kune zvakanakira zvayo. Nekushandisa laser senzvimbo yekupisa, kupinza nzvimbo ye spot kwakakurumidza, kwakanyatsojeka, nekupisa kushoma uye kushanduka kudiki kwe workpiece. Ma laser ane mukana wakanaka wekusvikika, izvo zvinogona kuderedza miganhu yenzvimbo uye yemaumbirwo panguva yekupinza nzvimbo. Haadi huwandu hwakawanda hwezvishandiso zvekubatsira, anogona kukurumidza kugadzirisa shanduko dzechigadzirwa, uye kusangana nezvinodiwa zvemusika. Nekukura nekukurumidza kwehupfumi hweChina uye kufambira mberi kuri kuramba kuchienderera mberi kwesainzi netekinoroji, kuvandudzwa kwetekinoroji yekuwedera nzvimbo ne laser chaiyoyafambira mberi nekukurumidza. Nekuda kwekubatsira kwayo kwekunyatsogadzirisa welding uye kumhanya kwayo kukuru, yave ichishandiswa zvakanyanya mukugadzirisa zvinhu zvesimbi zvakatetepa.
Mabhenefiti eLaser Precision Welding
Kutanga, ngatinzwisisei mabhenefiti ekushandisa laser precision welding:
- Inogona kupinza nzira dzakasiyana-siyana. Malaser ane divi rakasimba, izvo zvinoitawo kuti pave nemigumisiro yakanaka pakupinza zvinhu zvisina kurongeka.
- Kupinza kwakasimba. Mushure mekutarisisa, nzvimbo yelaser idiki ine simba rakawanda, zvichiita kuti danda riumbe nzvimbo yekupisa munguva pfupi. Mushure mekunyunguduka, kutonhora, uye kugadzika, musono wakasimba weld uye nzvimbo yacho zvinoumbwa.
- Kunyatso shongedza kwesimbi. Kugoverwa kwesimba relaser kune hunhu hwenguva nenzvimbo, zvichibvumira kuti danda rigovaniswe muzvikamu zvakasiyana-siyana zve optical zvekushanda panguva imwe chete, zvichipa vimbiso yakasimba yekunyatso shongedza kwesimbi.
- Kumhanya kwewelding nekukurumidza. Tekinoroji yelaser inosanganiswa netekinoroji yeCNC yekombuta. Panyaya yekuona michina mikuru uye masisitimu ekudzora kufamba, kubatanidzwa kwesisitimu kunosanganisira kuona panguva chaiyo uye kugadzirisa mhinduro, izvo zvinokurumidzisa kumhanya kwekugadzirisa ruzivo rwesisitimu uye zvinovandudza kushanda zvakanaka kwewelding.
