Prism and lens array coaxial light real-time coupling loss detection alignment system
PendingCN122260663Aimprove consistencyImprove stabilityMountingsSortingCoupling lossRefractive index
This invention belongs to the field of optical component mounting technology, specifically a real-time coaxial optical coupling loss detection and alignment system for prisms and lens arrays. It includes an automatic loading and unloading module for automatically loading the substrate, prisms, and lens arrays, and automatically sorting and unloading qualified and unqualified products. By adopting a technical solution that uses the real-time coaxial optical coupling loss detection value as the sole criterion for final alignment of the lens array, combined with a graded alignment strategy of visual coarse alignment and coaxial optical fine alignment, it solves the common industry pain point of existing pure visual alignment and passive alignment technologies that separate physical dimensional accuracy from optical performance. This results in the inability to compensate for manufacturing errors such as uneven refractive index and surface flatness deviations within optical components, leading to substandard optical performance despite meeting physical accuracy standards and low yield rates in mass production. By using dimensional and angular tolerances only as auxiliary constraints, it directly locks the global minimum coupling loss point, improving the consistency and stability of the product's optical performance.

An optimized NVH performance door exterior water-cutting structure
PendingCN122078145AImprove NVH performanceIncrease ballast capacityEngine sealsVehicle sealing arrangementsAgricultural engineeringCar door
This application discloses an optimized NVH performance exterior water-cutting structure for car doors, belonging to the field of automotive body sealing technology. The structure comprises a car door glass, an exterior water-cutting body, an exterior sheet metal, and an interior sheet metal. The distance between the upper inner wall of the exterior water-cutting body and the top end of the exterior sheet metal is A. An inner lip is provided at one open end of the exterior water-cutting body. An interference value B exists between the inner lip and the exterior sheet metal. A mounting hook is provided at the other open end of the exterior water-cutting body. The distance between the inner wall of the mounting hook and the interior sheet metal is C. This design significantly improves the first-time assembly success rate, effectively reduces labor hours and related costs, and significantly enhances the positional stability of the exterior water-cutting body after assembly, ensuring consistency in the interference between the water-cutting outer lip and the glass, resulting in a more uniform and neat assembly appearance.
