TBK Automatic Laser Screen Machine: Technical Specs & Workflow Guide
Introduction to Automated Laser Repair Technology
The integration of automation in mobile device repair has shifted focus toward precision equipment capable of handling delicate components. The tbk automatic laser screen machine represents a specific category of repair hardware designed to address the challenges of removing glass back panels and refurbishing screens. Unlike manual separation methods that rely on physical prying and variable heat sources, these systems utilize computer-numerical control (CNC) to direct laser energy, ablating adhesives with micrometer-level accuracy.
System Architecture and Compact Design
Modern repair environments, from retail kiosks to centralized refurbishment centers, often face space constraints. Engineering advancements have allowed for significant miniaturization of laser components without compromising output power.
The TBK 958ZE serves as a primary example of this design philosophy. It functions as a comprehensive, all-in-one unit that integrates the laser source, galvanometer scanner, and control computer into a single chassis. This "mini" form factor is designed to fit standard workbenches, contrasting with older industrial fiber lasers that required separate towers and monitors.
Key Hardware Components
-
Galvanometer Scanner: High-speed mirrors that direct the laser beam across the XY plane.
-
UV Laser Source: Operates at wavelengths designed to be absorbed by adhesives and paints while minimizing thermal penetration into the device's battery or logic board.
-
Motorized Z-Axis: Facilitates autofocusing by adjusting the vertical distance between the laser head and the device surface.
Operational Workflow and Efficiency
The primary function of a tbk automatic laser screen machine is to reduce the cycle time for back glass removal. Manual removal can take up to an hour and poses injury risks from glass shards. Automated laser ablation standardizes this process.
Processing Speed
Data indicates that the TBK 958ZE can complete a back glass removal cycle in approximately 4 to 8 minutes, depending on the severity of the glass damage and the specific model of the device. This throughput allows technicians to handle multiple repairs in the time it previously took to complete one.
Software Integration
Efficiency is further supported by the built-in operating system. The machine includes a pre-loaded drawing library containing templates for various smartphone models.
-
Real-time Updates: The system supports wireless connectivity to download new templates as manufacturers release new devices.
-
Template Accuracy: Blueprints are designed to strictly define "safe zones," preventing the laser from firing over wireless charging coils, camera modules, or exposed flex cables.

Versatility: Marking and Engraving
Beyond repair functions, the tbk automatic laser screen machine offers utility in customization. The software allows users to import images or text files, controlling the laser's power and speed to mark various materials.
Supported Materials:
-
Metals: High-contrast marking on aluminum and stainless steel.
-
Plastics: Serialization or branding on polycarbonate shells.
-
Glass: Etching designs on flat glass surfaces.
Safety Protocols and Fume Extraction
Laser ablation of epoxy and adhesives generates smoke and particulate matter containing potential irritants. Operational safety relies on effective ventilation. The TBK 958ZE incorporates an internal fume extraction system. This design captures smoke directly at the ablation point, filtering particulates before recirculating the air. This eliminates the need for external ductwork in many scenarios, although proper workshop ventilation is always recommended.
FAQS
Q1: How does the autofocus feature work on the TBK laser machine?
A1: The machine utilizes a sensor to measure the precise distance between the laser lens and the object. The motorized Z-axis then automatically adjusts the height of the laser head to the optimal focal length, ensuring maximum energy density for effective cleaning or engraving.
Q2: Is a separate computer required to operate the TBK 958ZE?
A2: No, the TBK 958ZE is an all-in-one solution with a built-in computer and screen. It comes pre-installed with the necessary software and drawing files, requiring only a mouse and keyboard for operation.
Q3: Can the machine remove the front screen glass as well?
A3: While the machine can be used to remove the bezel frame (bracket) by ablating the adhesive holding the frame to the glass, the separation of the front glass from the LCD/OLED display typically requires additional equipment like a heated separator or freezing machine, though the laser can assist in frame removal.
Q4: What is the advantage of using a UV laser over other types?
A4: UV lasers (often referred to as cold lasers) have a smaller focal spot and create less thermal stress (Heat Affected Zone) on the surrounding material compared to infrared or fiber lasers. This makes them safer for use on delicate electronic devices where heat management is critical.
