Ipinnu Fọọli Fọọmu Ejò ni Yiyi-si-Roll (R2R) Iṣelọpọ Circuit Rọ

1. Gbongbo Okunfa ti Wrinkling

Awọn ifosiwewe bọtini ti nfa fifọ foil bàbà ni awọn ilana R2R:

• Aiṣedeede ẹdọfu: Idojukọ wahala agbegbe nitori awọn gradients ẹdọfu.

• Iyipada ninu CTE: Ejò (17 ppm / ° C) vs. PI (35 ppm / ° C) awọn iyatọ imugboroja.

• Roller abawọn: aiṣedeede (> 0.01 mm / m) tabi idoti dada.

• Lamination awọn abawọn: Iwọn otutu ti kii ṣe aṣọ / titẹ tabi sisan resini.

2. Iṣakoso ogbon

(1) Ẹdọfu System ti o dara ju

• Iṣakoso ẹdọfu pipade-lupu:
  Servo Motors + awọn sẹẹli fifuye ṣetọju ẹdọfu laarin ± 0.1 N / mm.

• Taper ẹdọfu:
  Ibajẹ ẹdọfu ti o pọju lakoko isọdọtun (�=�0×(�0/�)�T=T0​×(D0​/D)n, n=0.8–1.2).

• Anti-wrinkle rollers:
  Awọn rollers itankale ade (R=1500 mm fun 500 mm oju opo wẹẹbu).

(2) Gbona-Mechanical Management

• Zoned otutu iṣakoso:
  Awọn agbegbe 5–8 pẹlu ≤3°C gradient (preheat=80°C, akọkọ=180°C, itura=50°C).

• Isokan titẹ:
  Awọn paadi silikoni ( Shore A 30–50) tabi awọn eto amuduro afẹfẹ fun> 95% isokan.

(3) Imọ-ẹrọ Ohun elo

• Kekere-roughness Ejò:
  Fáìlì tí a ṣe ìtọ́jú ìpadàbọ̀ (Rz=1–2 μm) dín ìforígbárí kù.

• Sobusitireti pretreatment:
  Ar/O₂ mimu pilasima ṣiṣẹ (500 W, 30 s) gbe agbara dada soke si 50 mN/m.

• Alemora ti o dara ju:
  Awọn akiriliki ti nṣàn ti o ga (viscosity

(4) Itọju Ẹrọ

• Rola odiwọn:
  Titete lesa osẹ (± 0.001 mm) ati ayewo oju (Ra

• Itọju eto wakọ:
  Lubrication itọsọna laini ati atunṣe ẹhin ẹhin jia (

3. Real-Time Abojuto

• Ayewo opitika:
  Awọn kamẹra ọlọjẹ laini (5000 fps) + CNN algorithm ṣe awari awọn wrinkles 0.1 mm².

• Lesa profilometry:
  Awọn wiwọn flatness (

• Aworan gbona:
  Ṣe abojuto iwọn otutu (± 2°C ala itaniji).

4. Ilana Ilana

5. Awọn Iwadi Ọran

• Ọran 1: 50μm PI + 12μm Cu bankanje

  • Solusan: Tan rollers + taper ẹdọfu (n=0.95)

  • Esi: Wrinkling dinku lati 5% si 0.3%, 20% ti o ga julọ.

• Ọran 2: Ga-igbohunsafẹfẹ LCP sobusitireti

  • Ṣiṣẹ pilasima + lamination timutimu afẹfẹ

  • Esi: Dk iyatọ
