Automatic Blue-laser Mirror Alignment System

Our company’s independently developed Automatic Blue-laser Mirror Alignment System(Model: OA9000-PBM) is designed for the automated production of array semiconductor fiber-coupled pump lasers. This system can automatically assemble semiconductor laser mirrors and features a pneumatic and vacuum structure design to ensure efficient material handling and positioning. The system employs a high-precision automatic sliding platform to ensure precise movement in six-dimensional space. We offer a twelve-axis intelligent controller and proprietary operating software. Compared with the previous generation OA9000-PLM system, the OA9000-PBM uses collected beam spot images to achieve fully automatic mirror coupling. This automation reduces the need for skilled operators and greatly improves product consistency.

This system comprises a motion unit, automatic dispensing unit, imaging unit, control unit, and programmable control software. The core motion unit features Japanese imported motors with high accuracy and long service life, ensuring long-term stable operation of the system. The combination of efficient image algorithms, our unique control technology, and dispensing design ensures that the system’s comprehensive performance is comparable to that of imported equipment from abroad.

Single-channel coupling time (excluding curing)
  • The system is capable of automatically powering up chips, picking up reflectors, fine-tuning couplings, dispensing and curing, and saving customer data to their database;
  • The reflector picking fixture is equipped with a vacuum sensor, which will automatically stop and alarm if the reflector cannot be picked up;
  • The equipment is compatible with multiple products, and the spacing and height of each channel can be adjusted as required;
Coupling efficiency
  • At least one continuous automatic coupling of all reflectors for a single product can be achieved in the specified order according to the process requirements, without touching and damaging the customer’s fibers during movement;
  • It is possible to freely select a certain optical path for coupling, rather than simply coupling in a specific order (from reflector 1 to reflector N), so that users can rework the reflector coupling of a certain optical path as needed;
  • Automatic adjustment of the base position, and automatic lowering of the power probe;
Linear slide resolution
  • Automatic recognition of the mirror position, and automatic smooth placement into the coupling area;
  • The system utilizes an automated process for coupling mirrors by analyzing the characteristics of the beam spot. This is achieved by collecting near-field and far-field images after the chip is powered on. The efficient automatic alignment algorithm facilitates the successful completion of the mirror coupling process;
  • The power-up process can gradually increase from low current to rated current;
Rotary slide resolution
  • Uniform distribution of dispensing, with dispensing length adjustable within 3-9mm;
  • The system encompasses multiple modes, including Operator Mode and Engineer Mode. The Operator Mode boasts a straightforward and user-friendly interface that is easy to navigate, whereas the Engineer Mode is fully functional and facilitates convenient debugging. It enables manual control of each module and can modify programs to accommodate product processes. It is proficient in performing various sensor tests, dispensing tests, and power-up tests.
