Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of material bending, in particular to a precision bending tool. Background Art
[0002] During the operation of the dicing machine, when non-contact height measurement or visual air blowing steps are required, a large amount of dust and water mist will be generated during the cutting process. These substances may interfere with the height measurement fiber optic head or visual lens and affect the accuracy, thereby affecting the overall cutting or processing quality. In order to solve this problem, two sets of pipes are installed on the fiber optic head of the sensor, which are used for water blowing and air blowing cleaning operations respectively; an air blowing pipe is set under the visual module. By blowing air, the water mist or other impurities left on the workpiece surface and the cutting path during work can be effectively cleaned, and the dust and impurities on the lens surface can be effectively removed, ensuring that the image captured and analyzed by the visual system is clear and improving the recognition accuracy. At present, vises and wire cutters are usually used for pipe bending operations. Although this method is relatively simple to operate, the shape consistency of the processed pipe is poor, and the bending angle is not convenient to be precisely adjusted, which to a certain extent affects its use effect.
