Te tukanga whakaputa rama PC

He hua tino noa ngā ārai rama i roto i te oranga o ia rā. Ko ngā rauemi e whakamahia ana mō ngā ārai rama PC he rauemi PC/PMMA kua horapa. Ka taea e mātou te hanga i ēnei rauemi e rua. Neke atu i te 17 tau o mātou wheako ki te hanga pokepoke, ā, neke atu i te 100 ngā tauira hanga ārai rama. Koinei te tukanga whakaputa o ngā ārai rama.

1. Te tātaritanga tono me te hoahoa matihiko

Te whakatauira mahi whatu

Whakatauira mārama: Whakamahia a LightTools, a Zemax OpticStudio rānei hei whakatū i te tauira ara mārama hei whakarite kia ≥92% te whakawhiti mārama o te ārai rama (ngā āhuatanga o te rauemi PC) me te karo i te kanapa (UGR<19);

Manatoko hanganga: Whakamahia te āhua ANSYS hei arotau i te matotoru o te pakitara pokepokea (1.5-3mm noa), hei whakataurite i te mama me te ātete pānga (ka taea te tu atu i te pānga o te pōro taka 3kg).

Te hoahoa 3D o ngā pokepokea ai

Rautaki pato: Mō ngā mata uaua (pērā i ngā tauira Fresnel), ka whakamahia ngā rārangi pato kore-taurite, ka honoa ki te tikanga tokotoko hononga reti toru-ahu (te ātete koki ±0.01°);

Whakamatao ōrite: Mā ngā awa wai koranu titanium kua tāia ki te 3D (diameter 1.2-2mm) ka whakarite kia ≤±1.5℃ te piki me te heke o te pāmahana o te pokepokea ai, kia kore ai e mā te rauemi PC i te ahotea.

2. Te miihini tika me te maimoatanga mata

Hangarau matua:

Mira kōhao, mīhini tino tika e rima-tuaka (GF Machining Solutions), taratara o te mata Ra≤0.02μm

Te whakairo hanganga moroiti, te tukanga whakahiato taiaho femtosecond + nanoimprint, te hohonutanga Fresnel 0.05mm±0.003mm

Te tukatuka irahiko, te miihini tuku hiko o ngā irahiko karāpeti (te āputa tuku 0.03mm), te koki taha R ≤0.1mm

Te maimoatanga whakapakari mata

Te whakakanapa taumata-whatu: Te whakakanapa maha-wāhanga me te gypsum taimana (mai i te W40 ki te W0.5), me te whakakanapa magnetorheological (MRF) hei whakakore i te kino o raro i te mata;

Paninga Ārai-piri: Ka whakaitihia e te paninga waro rite-taimana (DLC) (me te matotoru o te 2-3μm) te kaha tango ki raro i te 5kN, ā, ka roa ake te ora o te pokepokea ai ki te 800,000 pokepokea ai.

3. Manatoko whakamātautau pokepokea ai me te arotautanga whakaputa papatipu

Matapihi tukanga werohanga werohanga

Whakahaere pāmahana: Te pāmahana o te oko 280-310℃ (te taupū rewa PC 18g/10min), te pāmahana pokepokea 90-110℃ (hei ārai i ngā karawarawa rauemi makariri);

Pīkoi pēhanga: Te pupuri pēhanga e toru ngā wāhanga (60MPa→45MPa→30MPa), te tere whakahekenga utu 0.6-0.8%.

Te whakatikatika hapa-katia

Kua whanake te raina whakarewa, ā, kāore i te tika te tūnga o te kuaha, ka hua ake te huihuinga o ngā rerenga maha. Whakatikatikahia te wā o te ngira takirere wera (hapa ±5ms)

Te whakarerekētanga o te ira, te hinga o te hanganga moroiti o te pokepokea ai, te oro koretake rānei, te whakatikatika ā-rohe me te hanga hihi katote (rahi whakatikatika 0.005mm)

Te pakaru o te ahotea, te korenga o te pari whakahoro (<1°) te tere whakahoro rānei, te whakanui ake i te maha o ngā pine whakahoro (1 mō ia 100cm²)

4. Ngā kaupapa matua o te hanga pokepokea ai:

Te mahi whatu me te hoahoa hanganga

Te tuku mārama me te whakahaere ara whatu

Hanganga moroiti o te mata: Te hoahoa o te karāhe Fresnel nanoscale (tika hohonu ±0.003mm), ka tutuki mā te whakairo laser, mā te hiko rānei, me te koki marara mārama o te ≤15° me te karo i te kanapa (me <16 te uara UGR);

Te ōritetanga o te matotoru o te pakitara: Ka whakamahia te pūnaha arotautanga topological (ANSYS Discovery) hei whakataurite i te tuku mārama me te kaha. Ko te matotoru o te pakitara he 1.2-2.5mm, ā, ka whakahaerehia te manawanui i roto i te ±0.05mm. Ngā rautaki wehewehe me te tango i ngā raina

Wehewehenga kore taurite: Mō ngā mata piko kore taurite (pērā i ngā ārai rama he āhua rau), ka whakamahia ngā reti 3D me ngā tokotoko hono matua waipēhi. Ko te koki tauwehenga rārangi wehe he ≤0.5° kia kore ai e mura.

Te pari whakawātea: Ko te pari o te mata whatu ≥1.5°, me te pari o te mata kore-whatu ≥0.8°. Ka whakamahia e te pūnaha pana he pine pana uku silicon nitride (tauwehenga waku <0.1).

Te arotautanga mahi tahi o ngā rauemi me ngā tukanga

Te kōwhiringa o te maitai pokepokea ai

Te maitai kua orohia rawatia: Ko te S136 SUPREME (HRC 52-54) te German Gritz 1.2085 ESR rānei (kua orohia ki te whakaata ki te Ra 0.008μm) te mea e pai ake ana;

Maimoatanga ātete-waikura: Kua pania te mata ki te paparanga waro rite-taimana (DLC) (2-3μm te matotoru), ka taea te ātete ki ngā hau waikawa i puta mai i te pirau pāmahana teitei o te PC.

Mena kei te hiahia koe ki te whakarite i tētahi ārai rama PC rite, ka taea e koe te haere mai ki a mātou. Ka taea e mātou te whakapuaki i ngā momo kēhi maha kua mahia e mātou, kia taea ai e koe te kite i tō mātou kounga me te wheako i ā mātou ratonga.
