Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If COB module assembly process is developed from scratch, then customization and integration flexibility are improved, but process complexity and development time increase
Solution Approach 1:
The coupling platform is divided into independent functional modules: lens clamping mechanism, PCB clamping mechanism, positioning system, and bonding system. Each module can be adjusted and optimized independently, reducing overall process complexity while maintaining integration flexibility
Solution Approach 2:
The coupling platform is designed as a multi-functional assembly system that can handle lens clamping, PCB positioning, alignment, and bonding operations in one integrated platform, reducing the need for multiple separate processes and tools
2Ease of manufacture
If manual assembly methods are used, then equipment investment is reduced, but assembly precision and production efficiency deteriorate
Solution Approach 1:
The platform incorporates adjustable and movable components such as the lens clamping mechanism with movable parts that can be positioned precisely during assembly, providing mechanical precision without requiring complex automated equipment
Solution Approach 2:
The coupling platform serves as an intermediary mechanical system that provides precise positioning and alignment features (positioning holes, guide rails, adjustable clamps) to enable accurate assembly without direct automated control systems
3Productivity
If cyclic lens replacement is implemented, then production efficiency is improved, but mechanism complexity increases
Solution Approach 1:
The lens clamping mechanism is designed with a cam-driven movable part that can be rotated to sequentially clamp different lenses in a cyclic manner, enabling continuous production while using a relatively simple rotational mechanism
Solution Approach 2:
The movable part of the clamping mechanism automatically engages and disengages lenses through its rotational motion, with the cam profile itself providing the timing and positioning for lens replacement without requiring additional control mechanisms

AI summary
A coupling platform of SFP+COB module assembly for photoelectric communication, which comprises a lens clamping part, a PCB clamping part, a coupling adjustment part and a supporting part, wherein the lens clamping part comprises a clamping seat, a movable part, a cam, a connecting seat, a fiber optic patch cord limit plate and a fiber optic patch cord; the PCB clamping part comprises a PCB socket, a clamping jaw and a gas jaw The main body of the coupling adjustment part is a multi-shaft fine-tuning rack. and the supporting part comprises a cushion block and a platform bottom plate. The clamping seat, the movable part and the cam are combined, thereby enabling the cam to drive the movable part to slide up and down in a clamping groove of the clamping seat during rotation. When the movable part moves to an upper end, an LC light port of a plastic lens can be inserted into the clamping seat without obstruction. When the movable part moves to a lower end, the LC light port of the plastic lens is limited by a limiting gap of the movable part. When the cam rotates, the cam drives the movable part to slide to the upper end to replace the plastic lens with a new plastic lens. Accordingly, the present invention solves the technical problems of enabling the plastic lens to be easily positioned and bind a PCB, thereby achieving the beneficial effects of improving the quality and the efficiency and reducing the manufacture cost.
