Automatic Laser Assembly System for Automotive Lidar

Our company’s independently developed Automatic Laser Assembly System for Automotive Lidar (Model: OA-PA1000L-C00) is designed for automated FC connector insertion into the housing and subsequent adhesive curing. It excels in material identification (Disk fiber and enclosure) and seamlessly integrates program-controlled automatic loading and unloading. The module facilitates ceramic core gripping, de-capping, cleaning, secondary positioning, adhesive dispensing, visual guidance, and curing, ensuring optimal performance.

The comprehensive system comprises a feeding unit, decoding unit, picking unit, de-capping unit, FC connector cleaning unit, secondary positioning unit, visual guidance unit, FC connector unit, dispensing unit, UV curing unit, control unit, and programmable control software. Leveraging advanced visual guidance, the core component precisely inserts the FC connector into the nozzle and end cap of the housing using a bespoke fixture. The process includes UV pre-curing and deep curing to guarantee flawless functionality. The high-precision embedded cast iron module guarantees long-term stability, delivering exceptional motion control and high repeatability. Our ingenious combination of efficient algorithms, proprietary control technology, and dispensing design ensures that the system’s overall performance is on par with imported equipment.

Duration of single-channel connector insertion operation (Including curing process)

The equipment is designed to accommodate a diverse range of fiber optic box products, supporting both straight and bent pin configurations;
Each fiber tray is equipped with a QR code label for comprehensive traceability. Automated QR code scanning enables batch tracing of fibers and automatic input of tube holder QR code information into the Manufacturing Execution System (MES) for connection tracing;
The FC connectors are automatically inserted into the output holes of the fiber tray. Following adhesive application, customized connector ends are accurately positioned into component nozzle holes and subjected to UV curing;
During the arrangement of ceramic fibers, strict adherence to process requirements and designated orientations ensures orderly stacking, mitigating the risk of material entanglement during fiber retrieval. Silicone gel fingers are utilized for clamping, offering protection against fiber damage during winding;
The fiber optic is automatically retrieved from the tray and placed in the cap removal station, ensuring optimal gripping force to accomplish successful cap removal;

Achieving accurate axial alignment of the ceramic fiber optic requires maintaining a contamination-free end face. The alignment fixture incorporates non-stick processes and undergoes regular cleaning, while precautions are taken to avoid obstructing the fiber optic passageways;
Fiber optic boxes are systematically placed in the tray according to specified orientations, ensuring adherence to process requirements. The fiber tray is designed with foolproof (pokayoke) mechanisms to prevent incorrect placement;
The fiber optic boxes within the tray are automatically grasped and positioned in the alignment fixture. They are then transported by the transfer module to the visual positioning area, where precise positioning is accomplished based on the tube nozzle and FC nozzle;
After securing the customized connector, the adhesive dispensing mechanism evenly coats the ceramic surface through rotational movement, guaranteeing ample adhesive coverage with a 360° dispersion;
The automated program can be paused and resumed at any time, allowing operators to perform additional operations as needed;

After visually guided positioning of the fiber optic enclosure, the connector retrieving and extracting module smoothly inserts the customized connector and FC ceramic connector into their respective component nozzle holes and fiber tray output holes;
Equipment operation is controlled through the Supervisory Control and Data Acquisition system. Alarm and fault resolution instructions are prepared in Chinese. The main control panel features emergency stop, stop, start, reset buttons, and other functionalities;
In the event of faults such as barcode reading errors, empty tray in the clip-type storage compartment, material retrieval failure, cap removal failure, insufficient UV adhesive, visual recognition failure, incomplete connector insertion, lack of electrical current, or malfunctioning electrical components, the program can issue alarms, automatically halt operations, and provide troubleshooting suggestions;

The system incorporates various modes, including operator mode and engineer mode. The operator mode offers a simple, intuitive, and user-friendly interface, while the engineer mode provides comprehensive functionality and facilitates easy debugging. It allows manual control of each module, convenient program alteration to accommodate product processes, and execution of individual actions for simplified adjustments.

S/N	Name	Remarks
1	Ceramic Fiber Optic Retrieval and Placement	The material tray incorporates a clip-based loading mechanism, enabling the production line operator to focus on precisely arranging materials onto the designated tray. Upon completion of material retrieval and placement, the tray smoothly retracts back into the clip-based storage compartment.
2	Cap Removal Station	Cap Box for Protective Cap Recycling
3	Fiber Optic Cleaning and Directional Switching	Cleaning and Material Rotation for Ceramic Core Axial Alignment
4	Enclosure Retrieval and Placement	The material tray incorporates a clip-based loading mechanism, enabling the production line operator to focus on precisely arranging materials onto the designated tray. Upon completion of material retrieval and placement, the tray smoothly retracts back into the clip-based storage compartment.
5	Vision Positioning Station	After the visual positioning is completed, the enclosure is transferred from the module to the Ceramic Connector Station
6	Dispensing Station	After securely clamping the ceramic core, the adhesive dispensing mechanism rotates the ceramic surface 360° to ensure precise and uniform adhesive application
7	Connector and Curing	Once the enclosure is visually aligned, the ceramic connector is inserted into the enclosure using a gripper, enabling UV pre-curing and final curing.
