The primary function of a screen repair machine lcd separator is to decouple the glass lens from the display panel (LCD or OLED) or to remove the display assembly from the device frame. This process relies on a combination of controlled thermal energy to soften the Optical Clear Adhesive (OCA) and mechanical separation, typically achieved via a molybdenum cutting wire.
Correct operation is critical to preventing damage to the polarizer film or the display matrix itself. Modern repairs, particularly on curved "Edge" displays, require equipment with higher mobility and stability than traditional static heating plates.
Before initiating the separation, the workstation must be prepared with the necessary safety gear and tools, including heat-resistant gloves and cutting wire (typically 0.03mm to 0.08mm).
The heating element is the core of the operation.
Standard LCDs: Typically require a temperature setting between 80°C and 90°C.
OLED Panels: More sensitive to heat; precise regulation is necessary to avoid burning the organic layers.
It is essential to wait for the machine to reach a stable, constant temperature before placing the screen on the platform.
To perform a clean cut, the screen must be totally immobile. Machines equipped with dual vacuum pump systems provide superior suction compared to single-pump models. Ensure the silicone pad is clean and aligned with the vacuum holes to create a perfect seal.
Place the LCD assembly on the heating plate. Allow it to sit for approximately 30 to 60 seconds. This duration allows the heat to penetrate the glass and sufficiently soften the OCA glue layer beneath.
For standard flat displays, the process is linear:
Engage the vacuum pump to lock the screen in place.
Insert the cutting wire between the glass and the LCD.
Apply downward pressure with the wire to keep it against the glass surface, not the polarizer.
Move the wire in a sawing motion (left to right) while pulling it slowly towards the bottom of the screen.
Separating curved screens requires adjusting the angle of approach to follow the curvature of the glass. A static plate makes this difficult and increases the risk of cutting into the polarizer.
Using a machine like the TBK 988C facilitates this process through its mechanical adaptability.
Rotation and Tilt: The worktable on the TBK 988C allows for 360-degree rotation and left/right tilting.
Technique: Operator can tilt the platform to align the curved edge of the screen with the horizontal plane of the cutting wire. As the wire progresses around the curve, the technician rotates or tilts the platform, maintaining a straight cutting line relative to the gravity of the wire.
Stability: The built-in dual vacuum pump ensures the curved glass remains fixed even when the table is tilted at acute angles.
The following table outlines the recommended operational parameters for different separation tasks using a screen glass separator machine lcd.
| Screen Type | Recommended Temperature | Vacuum Requirement | Platform Orientation | Wire Thickness |
| Flat LCD (IPS) | 80°C - 90°C | Standard Suction | Fixed Horizontal | 0.05mm - 0.08mm |
| Flat OLED | 80°C | Standard Suction | Fixed Horizontal | 0.04mm - 0.05mm |
| Curved OLED | 80°C | High Suction (Dual Pump) | Tilted Left/Right | 0.03mm - 0.04mm |
| Cracked Glass | 80°C - 90°C | High Suction + Tape | Fixed or Tilted | 0.05mm - 0.08mm |
Note: If the screen glass is severely shattered, applying a layer of transparent tape over the cracks is necessary to maintain a vacuum seal.
Once the how to use lcd screen separator machine process is complete, residual OCA glue will remain on the display panel.
Keep the vacuum pump engaged to hold the LCD.
Use a glue removal tool or finger to roll off the bulk adhesive while the panel is still warm.
Clean the surface with an appropriate solvent (e.g., 8333 or alcohol) and a dust-free cloth.
To ensure longevity and safety:
Vacuum Ports: Regularly check vacuum holes for glass debris or glue residue which can reduce suction power.
Heating Plate: Wipe down the plate after every use to prevent adhesive buildup, which can cause uneven heating in future jobs.
Rotation Mechanism: For rotating units like the TBK 988C, ensure the locking mechanisms for the tilt and rotation angles are secure before starting work to prevent unexpected movement.
Q1: What is the ideal temperature for separating an iPhone screen?
A1: For most iPhone screens, a temperature range of 80°C to 85°C is recommended. Exceeding this temperature can damage the backlight on LCD models or the organic materials in OLED models.
Q2: How do I separate a screen if the glass is completely shattered and the vacuum won't hold?
A2: If the glass is severely cracked, air leaks prevent a vacuum seal. Apply a layer of wide clear packing tape over the shattered glass. This seals the cracks and creates a smooth surface for the vacuum pump to grip.
Q3: Why is a rotating separator better for curved screens?
A3: Curved screens have adhesive wrapping around the edges. A rotating and tilting separator, such as the TBK 988C, allows you to angle the screen so the cutting wire can follow the curve naturally without cutting into the display panel underneath.
Q4: What thickness of cutting wire should I use?
A4: For general use, 0.05mm or 0.06mm wire is standard. For curved screens or screens with very tight tolerances, a thinner wire (0.03mm or 0.04mm) is preferred to reduce separation stress.
Q5: Can I use the separator machine to remove the frame as well?
A5: Yes. The heating plate can be used to warm the entire device to soften the frame adhesive. Once heated, you can use clamps or pry tools to separate the frame from the housing, leveraging the machine's constant temperature capabilities.
