Projector Assembling Equipment Multi-Axial Lens Alignment

The patent introduces a multi-axial adjusting device that enables dynamic adjustment of the lens module in multiple directions (X, Y, Z axes) and angles (θ, φ) after initial fixation. This transforms the static fixed position into a dynamically adjustable position, allowing the lens module to be laterally shifted, tilted, and rotated for precise alignment with the light source while maintaining stability during operation.

The adjusting device is divided into multiple independent adjustment mechanisms: a three-axis translating mechanism for linear movement in X, Y, Z directions, and a two-degree-of-freedom rotating mechanism for angular adjustment. This segmentation allows each mechanism to be optimized independently and provides granular control over the lens module position and orientation.

The patent transforms the static fixed structure into a dynamic adjustable system with multiple degrees of freedom. The multi-axial adjusting device provides precise control over the lens module position (X, Y, Z) and orientation (θ, φ), enabling accurate optical centering while maintaining reasonable structural complexity through modular design.

The patent replaces manual alignment methods with a mechanical multi-axial adjusting device that provides precise, controllable movement. The device uses standard mechanical components (screws, rails, bearings) arranged in a systematic way to achieve sub-millimeter positioning and sub-degree angular adjustment, balancing mechanical simplicity with precision requirements.
