[0010] In the basic target positioning process of the laser processing system with machine vision, the template will easily change with the influence of external factors such as target background and material. The processing of workpieces with target positioning (such as PCB&FPC) needs to learn the target template data information separately, and repeated template learning will take more man-hours and reduce production efficiency

Embodiment Construction
[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0040] figure 2 It is a flowchart of a one-key positioning method in laser processing according to an embodiment. The method includes the following steps S110-S140.
[0041] Step S110: generating various standard target templates of the target in advance. The targets include one or more of circular targets, square targets and cross-shaped targets. The standard target template is used to match the target graphics obtained by the vision module in the workpiece during positioning, and serves as a standard for identifying targets.
[0042] This step can include:

The invention relates to a one-key positioning method and a laser machining method and system applicable to laser machining. The positioning method comprises the steps of generating various standard target templates of a target in advance; obtaining the type of a to-be-machined workpiece and the applied target type; selecting the standard target template corresponding to the type of the to-be-machined workpiece and the target type from the various standard templates; and performing positioning according to the standard target template. The laser machining method includes the positioning method. The laser machining method is applied to the laser machining system. According to the positioning method and the machining method and system, by generating the various standard target templates of different types of workpieces in advance, the learning time during positioning is omitted, and the positioning efficiency is improved.
