LASER FRAME TRACER

摘要

A laser frame tracer (12) including a laser measuring unit (20) with a laser (36) and one or more cameras (38, 40) for optically measuring dimensions of eyeglass frames (10). A frame carrier (22) is provided for moving the eyeglass frames (10) through a laser line emitted by the laser (36). The frame carrier (22) includes a linear carriage (44) and a rotary carriage (88). Movement of the linear carriage (44) and the rotary carriage (88) are controlled by an on-board computer (116) which collects image data from the one or more cameras (38, 40). Image data is processed to determine a 3D model from which selected dimensions for the eyeglass frames (10) may be measured. The dimensions may be stored in a cloud database for access by others in cutting lenses to fit the eyeglass frames (10).

主权项

1. A laser frame tracer, comprising:
a laser measuring unit including a laser and a camera, the laser selectively emitting laser light and the camera recording images of the laser light reflected from an eyeglass frame passed through the laser light; a linear carriage comprising:
a moveable platform; anda linear drive motor coupled to the platform, to move the platform with respect to the laser measuring unit; a rotary carriage mounted to the platform, the rotary carriage including a carrier pivotally mounted to the platform and a rotary motor connected to the carrier, the rotary carriage rotating the carrier to one or more selected angular positions with respect to the laser measuring unit; a clamp shaped to removably secure the eyeglass frame to the carrier; and a data processing unit storing the recorded images from the camera.
