Our Company's First-Generation Dual-X Dual-Y Four-Head Glass Sheet Labeling Machine Overcomes the Precision Placement Challenges of Mobile Phone Cameras

In today's era of continuous evolution in smartphone cameras, a single tiny camera module integrates multiple precision components such as lenses, filters, and textured film. Among these, the high-precision attachment of glass sheets and textured film directly affects imaging quality and product yield, making it one of the most challenging processes in camera manufacturing.

Facing this precision manufacturing challenge, our R&D team has officially launched the first-generation dual-X dual-Y four-head glass sheet labeling machine. With an innovative four-head parallel structure and micron-level motion control, it successfully achieves high-precision, high-efficiency attachment of smartphone camera glass sheets and textured film, injecting new technological momentum into camera module manufacturing.

The Industry Pain Point of Precision Attachment

As optical components protecting the lens, smartphone camera glass sheets require extremely high positional accuracy. The attachment of textured film (such as sparkling film or anti-glare film) must perfectly align with the glass sheet, as even slight deviations can cause defects such as misalignment, bubbles, or wrinkles.

Traditional placement equipment faces multiple challenges:

Efficiency bottleneck of single placement head: Single-head equipment struggles to meet high-volume production cycle time requirements

Insufficient alignment accuracy: Both glass sheets and textured film are transparent or semi-transparent materials, making visual recognition difficult

Easy deformation of flexible materials: Textured film is thin and soft, prone to stretching or wrinkling during placement

Accumulated errors from multi-process handling: Glass sheets need to proceed to subsequent processes after film attachment, with multiple positioning steps accumulating errors

How to achieve efficient and stable mass production while maintaining micron-level precision has become a common demand for camera module manufacturers.

Dual-X Dual-Y Four-Head Structure, A Breakthrough in Both Efficiency and Accuracy

The core innovation of our first-generation glass sheet labeling machine lies in its dual-X dual-Y four-head parallel structure. The ingenuity of this design includes:

Independent dual-X axis operation: Two X-axes can move simultaneously or independently without interference, enabling parallel operation

Coordinated dual-Y axis control: Two Y-axes work with the X-axes to form four independent working heads, each performing its own function

Simultaneous four-head operation: Four placement heads can pick, position, and attach simultaneously, significantly increasing output per unit time

Division of labor mode: Supports two heads for glass sheet loading and two heads for textured film attachment, creating an assembly line operation

This structural design increases placement efficiency by more than three times compared with traditional single-head equipment, meeting high-volume production requirements while maintaining accuracy.

Micron-Level Alignment, Overcoming Transparent Material Recognition Difficulties

Both glass sheets and textured film are transparent materials, making edge contour accurate identification difficult for traditional vision systems. To address this, the R&D team made deep optimizations to the vision alignment system:

High-resolution industrial camera: Equipped with a camera of tens of millions of pixels to capture fine features

Specialized light source design: Uses multi-angle, multi-spectrum light sources to enhance edge contrast of transparent materials

Sub-pixel positioning algorithm: Achieves 0.01mm-level edge positioning accuracy through image processing algorithms

Dual-mark point alignment: Simultaneously recognizes mark points on both glass sheet and textured film to calculate the optimal attachment position

Guided precisely by the vision system, the equipment maintains placement accuracy stably within plus or minus 0.05mm, meeting the stringent requirements of high-end camera modules.

Flexible Placement Process, Protecting the Ultra-Thin Textured Film

Textured film is often less than 0.1mm thick, soft and prone to deformation, making it very easy to create wrinkles or bubbles during placement. Addressing this challenge, the equipment features innovative process controls:

Vacuum suction picking: Uses micro-porous suction technology to gently pick up the textured film, avoiding mechanical clamping deformation

Roller-type attachment: The placement head uses a roller structure, progressively applying from one side to the other, effectively expelling bubbles

Real-time pressure monitoring: Monitors pressure values continuously during placement to ensure uniform and consistent attaching force

Adaptive height control: Automatically adjusts attachment height based on glass sheet surface flatness, avoiding hard collisions

This series of flexible process designs enables the textured film to be attached flatly and firmly to the glass sheet surface, without bubbles, wrinkles, or misalignment.

Intelligent Control System, Convenient Changeover and Adjustment

Given the production characteristics of multiple mobile phone models and batches, the equipment is equipped with an intelligent control system:

One-click changeover function: Enter product parameters, and the equipment automatically adjusts pickup position, placement coordinates, and operating parameters

Recipe management mode: Supports storage and recall of multiple product recipes, reducing changeover time to within 5 minutes

Data traceability system: Records time, position, and pressure data for each placement, achieving full-process quality traceability

Real-time monitoring and alarm: Monitors abnormal situations in real time with alarms, ensuring stable and controllable production processes
