The 500×700 Film Laminating Machine (Model 9TU-M068C)

1. Dual Servo-Driven Platform System The upper platform is driven by a servo motor with 180° automatic center-rotation flip — bringing the film substrate from the loading position to the bonding position with precise, repeatable positioning. The lower platform uses a servo motor + ball-screw drive for horizontal linear movement, providing smooth, controlled travel across the full 700 mm bonding stroke. Both axes deliver control-axis repeatability of ±0.05 mm.

2. Strong / Weak Vacuum Switching — Anti-Stretch Technology The lower platform is equipped with a dual-stage vacuum switching system (strong vacuum for secure clamping; weak vacuum during the bonding stroke). This graduated vacuum control prevents soft films — including thin OCA, conductive films, and ITO films — from stretching or deforming under roller pressure across the full 500 × 700 mm working area, preserving dimensional accuracy and eliminating stretch-induced bubble patterns.

3. High-Straightness Polyurethane Roller — Uniform Bonding Pressure The Ø35 × L520 mm polyurethane roller (Shore A 55–60) is supported by bearings at both ends with no idler/back-roller support. Its vertical independent lifting with X-axis displacement compensation eliminates pressure marks at the contact start point. Laminating force is adjustable up to ≤75 kg, and bonding speed is programmable up to <300 mm/s — configurable per product recipe.

4. PLC + Touch-Screen HMI Control Full PLC automatic control with a touch-screen human-machine interface provides clear parameter management including timing, count, position, and blowing delay settings. Automatic and manual operation modes are selectable. Product recipe switching for existing substrates takes <15 minutes; new substrate configurations take <30 minutes.

5. Mechanical Corner Positioning with Micrometer Y/θ Adjustment Substrate alignment uses mechanical corner positioning as the primary registration method. Y-axis and θ-angle fine adjustment is performed via micrometer for precise tilt correction. X-axis coordinates are set automatically. This system achieves a fitting accuracy of ±0.20 mm (excluding material error) and equipment repeatability of ±0.15 mm.

6. High-Flatness, Hard-Anodized Vacuum Platform Both upper (L735×W520 mm) and lower (L725×W520 mm) platforms are manufactured from high-performance, non-deforming material and finished with hard anodizing to resist wear and maintain flatness precision over extended production cycles. Vacuum hole pitch is Ø1.0 mm at 15×15 mm spacing, providing uniform adsorption across large substrate surfaces.

7. Rigid Steel-Structure Frame — CLASS 1000 Compatible The machine base is constructed from heavy-duty steel structure for high rigidity and vibration resistance, supporting precise bonding of thin optical films without platform deflection. Working environment: 25±5°C, humidity 60±5%, cleanliness CLASS 1000. Optional FFU (2 sets), ion fans (2 sets), dust lamp (2 sets), and safety light curtain are available as accessories.

8. Integrated Built-in Vacuum System The machine includes its own integrated vacuum system — no external vacuum pump required. Air supply connects to a standard external air compressor (5–7 kg/cm², Ø12 quick-connect fitting, 1000 L/min consumption).
