Semi-Automatic Bonding Machine

Semi-Automatic Bonding Machine

A semi-automatic bonding machine for LCD, TFT, OLED, ACF, COF, IC, and FPC is the versatile heart of mid-volume display and flex-circuit production. It marries operator control with automated precision, allowing engineers to load glass or flex manually while the machine automatically laminates ACF, aligns chips or flex tails, and bonds under controlled heat and pressure. Every smartphone OLED, foldable hinge, 8-K TV source driver, or automotive cluster you touch has passed through such a platform. This guide explains physics, hardware, software, specs, applications, trends, and maintenance so Google instantly ranks you for “semi-automatic bonding machine”, “LCD bonding machine semi-auto”, “OLED ACF semi-auto bonder”, “COF semi-automatic bonding machine”, “IC semi-auto bonder”, “FPC semi-auto bonding machine”, and every high-value permutation.

1. Why “Semi-Automatic” Matters in Mid-Volume Production

• Cost vs. Throughput: Capex is ~40 % lower than fully automatic lines; ideal for 600–3,000 UPH .
• Flexibility: Operators can swap LCD/TFT/OLED sizes (1–55 in) or COF/IC/FPC types in < 15 min .
• Repair & R&D: Manual loading allows easy rework of defective units or small-batch validation .
• Skill Transfer: Technicians learn vision alignment and thermal profiling before upgrading to fully automatic lines .

2. Physics: The Semi-Automatic Two-Stage Dance

1. Operator Load: Places LCD/TFT/OLED panel or FPC onto vacuum chuck; barcode confirms product ID.
2. Automated ACF Lamination: Machine cuts 1–3 mm ACF strip and tacks it at 80 °C, 0.2 MPa.
3. Semi Vision Alignment: Operator jogs chip/flex under live 12 MP camera; AI calculates X, Y, θ; one-button lock achieves ±0.003 mm .
4. Automated Bond:
   • COG/COF/IC: 160–220 °C, 0.8–1.5 MPa, 2–4 s
   • FOG/FOB/FPC: 140–200 °C, 0.6–1.2 MPa, 2–4 s
5. Operator Unload: Removes bonded assembly; next cycle starts.

Because the operator controls load/unload and final alignment, the machine can handle multiple display sizes, multiple bond heads, and small-batch R&D without reprogramming a robot.

3. Step-by-Step Semi-Automatic Workflow (Generic Multi-Mode)

1. Operator Load: Places 1–55 in LCD/TFT/OLED or FPC onto vacuum chuck; barcode scanner confirms product ID.
2. Atmospheric Plasma Cleaning: Raises surface energy to > 60 dynes for ACF wetting.
3. Semi ACF Lamination: Operator presses “Start”; machine cuts 1–3 mm ACF strip and tacks it at 80 °C, 0.2 MPa.
4. Semi Vision Alignment: Operator jogs chip/flex under live 12 MP camera; AI calculates X, Y, θ; one-button lock achieves ±0.003 mm .
5. Semi Bond:
   • COG/COF/IC: 160–220 °C, 0.8–1.5 MPa, 2–4 s
   • FOG/FOB/FPC: 140–200 °C, 0.6–1.2 MPa, 2–4 s
6. Operator Unload: Removes bonded assembly; next cycle starts.

Cycle time: 6–10 s (operator dependent), throughput: 600–3,000 UPH .
