| Application Field | Examples of Mounted Auxiliary Materials | Technical Difficulties |
|---|---|---|
| Fast Charging Power Supply | Graphene heat dissipation film on the side surface, anti-slip silicone pad on the bottom surface | Stability of high-temperature adhesive, curved surface fitting |
| Car Charger | Waterproof sealing rings on the three surfaces, shock-absorbing foam | Simultaneous mounting of multiple materials (foam + rubber) |
| Wireless Charger | Coil shielding film, bottom label | Prevention of wrinkles for ultra-thin auxiliary materials (0.1mm) |
I. Core Functions of the Equipment
Simultaneous Multi-sided Mounting
It can automatically complete the attachment of various auxiliary materials such as anti-slip pads, heat dissipation films, labels, and insulating sheets on the front, back, and side surfaces of the charger at the same time.
It supports the mounting on irregular curved surfaces, such as the recessed area of the USB-C interface and the curved corners.
High-precision Positioning
Adopting a multi-station vision system (with 3 to 6 CCD cameras), it can achieve synchronous recognition of the reference points on the three surfaces, with a positioning accuracy of ±0.05mm.
Flexible Model Change
With a modular fixture design, it can switch between different models of chargers (such as 20W/65W fast chargers, car chargers, etc.) within 5 minutes.
II. Technical Implementation Principles
Feeding and Sorting System
Three-channel Feeding: There are independent feeding tracks corresponding to the auxiliary materials on the front, back, and side surfaces respectively (coil materials/Tray trays/vibrating trays).
Manipulator Sorting: The SCARA robot is equipped with customized suction nozzles (silicone/static electricity adsorption) to avoid deformation of the auxiliary materials.
Multi-sided Positioning Technology
3D Vision + Laser Ranging: Obtain the three-dimensional contour of the charger through point cloud modeling, and dynamically adjust the mounting path.
Rotating Fixture: The fixture is driven by a servo motor to rotate 360°, ensuring that there are no blind spots when attaching the auxiliary materials on the side surfaces.
Mounting and Pressing
Six-axis Manipulator: Equipped with a flexible pressing head (such as a silicone roller), it can adapt to the pressure control on curved surfaces (adjustable from 10 to 100N).
Simultaneous Pressing: The pneumatic pressing rods on the three surfaces operate synchronously to prevent displacement caused by unilateral stress.
Quality Inspection
Multi-angle AOI Inspection: Infrared + color cameras are used to detect the integrity of the mounting on the three surfaces (lack of materials, skewness, bubbles).
Force Feedback System: Monitor the pressing force curve in real time and automatically compensate for the thickness tolerance of the auxiliary materials.
