Description

Technical Field

[0001] The invention relates to the technical field of laser welding of spectacle frames, and in particular to a multi-angle laser welding device for spectacle frames. Background Art

[0002] As a precision optical accessory, the welding quality of eyeglass frames directly affects the product's aesthetics, structural strength and wearing comfort. Traditional eyeglass frame welding mostly uses arc welding or resistance welding processes, which have problems such as large heat-affected zone, significant material deformation, and rough welds, making it difficult to meet high-precision welding requirements. In recent years, laser welding technology has been gradually applied to the field of eyeglass frame manufacturing due to its advantages such as high energy density, low heat input, and high processing accuracy. However, existing laser welding devices still have the following shortcomings:

[0003] 1. Limited multi-angle adjustment: The structure of eyeglass frames is complex, and most welding points are located on curved surfaces or asymmetric positions. Existing equipment mostly relies on three-axis or four-axis motion systems, which makes it difficult to achieve multi-degree-of-freedom precise positioning, resulting in many welding dead angles and the need to frequently adjust the workpiece or laser head, which is inefficient.

[0004] 2. Poor coordination of double-stations: Some equipment adopts a single-station design, with loading and unloading and welding processes performed alternately, resulting in a long production cycle; while in the double-station device, the station switching mechanism has a slow response speed and insufficient positioning accuracy, which can easily cause welding misalignment or mold offset.

[0005] 3. Inaccurate mold positioning and clamping: Traditional molds rely on manual adjustment, which makes it difficult to quickly adapt to different types of eyeglass frames. In addition, uneven clamping force can easily cause the workpiece to loosen during welding, affecting the consistency of the weld.

[0006] 4. Low integration of automation and sensors: welding path planning relies on manual experience and lacks real-time correction function; the sensor system is imperfect, the welding position recognition and tracking accuracy is insufficient, and multiple calibrations are required, which restricts continuous production.

[0007] In response to the above problems, it is urgent to develop a multi-angle laser welding device with high flexibility, high precision and efficient coordination capabilities to improve the welding quality and production efficiency of eyeglass frames. Summary of the invention
