Abstract: A laser soldering system using dynamic light spot and a method thereof are provided. A laser module is controlled to radiate toward multi-lens to form a light spot on a soldering target for soldering, and a lens distance between the multi-lens is adjusted to adjust a light spot size. The disclosure may provide multiple heating densities respectively adequate to different soldering status via adjusting the light spot size when using same laser power, so as to improve the soldering quality.

Abstract: An automatic robotic arm system and a coordinating method for robotic arm and computer vision thereof are disclosed. A beam-splitting mirror splits an incident light into a visible light and a ranging light and respectively guides to an image capturing device and an optical ranging device arranged in the different reference axes. In a calibration mode, a transformation relation is computed based on a plurality of the calibration postures and corresponding calibration images. In an operation mode, a mechanical space coordinate is determined based on an operation image and the transformation relation, and the robotic arm is controlled to move based on the mechanical space coordinate.

Abstract: A laser processing device for processing a workpiece is provided, including a laser emitter, a lens module, a driving module, a camera module, and a processing unit. The lens module has a first lens and a second lens, wherein the laser emitter emits a laser beam through the first and second lenses to the workpiece. The driving module drives the first lens to move relative to the second lens. The camera module captures an image of the workpiece. The processing unit is electrically connected to the camera module and the driving module, wherein the camera module transmits an image signal to the processing unit according to the image of the workpiece, and the processing unit transmits a driving signal to the driving module according to the image signal, driving the first lens to move relative to the second lens. A method for processing a workpiece is also provided.
