Positioning device and method of overall puncture module equidistance densely-arrayed micro holes

Abstract

The invention discloses a positioning method of overall puncture module equidistance densely-arrayed micro holes. The method comprises the steps that a mini-sized CCD camera is demarcated to eliminate image distortion; a steel needle array of overall puncture is determined; binaryzation is conducted on an image and the image is signed, point-by-point traversal is conducted, then the distances between the center point of a cross cursor and four end points are controlled to be equal, and the fact that poisoning holes and needle distribution basic holes are coaxial; the relative position relationship between the needle falling holes and the needle distribution basic holes is calculated and obtained according to the relative position relationship between the needle falling holes and the positioning holes; a base plate is controlled to move transversely and longitudinally according to the steel needle array of the overall puncture, and therefore the positioning of the overall puncture module equidistance densely-arrayed micro holes is achieved. The positioning method of the overall puncture module equidistance densely-arrayed micro holes is used in the carbon fiber three dimensional fabric overall puncture technology, and the needle distribution basic holes are defined to the mini-sized holes on the upper left corner of a puncture template. The positioning method of the overall puncture module equidistance densely-arrayed micro holes provides necessary center position information of the needle distribution basic hole for a steel needle array distributing mechanism on the basis of the image and a cross-shaped laser, and puncture steel needles can be distributed conveniently.

Description

Technical field [0001] The invention relates to an auxiliary device in a carbon fiber three-dimensional fabric puncture molding process, in particular to a calibration system for micro holes of a puncture template in a puncture steel needle array placement device in a carbon fiber three-dimensional fabric integral puncture process. Background technique [0002] Three-dimensional fabric is a fiber-reinforced structure with the best performance developed in the past 40 years, mainly used in aviation, aerospace, automotive, medical and new technology fields. The integral puncture technology is a forming technology for three-dimensional fabrics. The integral puncture steel needle array refers to a puncture array formed by placing steel needles in thousands to tens of thousands of evenly spaced close-packed tiny holes in a puncture template. [0003] With the advancement of science and technology, people have gradually organically combined the previous manual processes, technology and i...

Problems solved by technology

Its disadvantages are: limited by the spot area of ​​the laser, it can only be used to accurately and quickly locate the abdominal wall puncture holes of patients with a diameter of about 10mm, and is not suitable for equidistant dense puncture holes with a diameter of less than or equal to 2mm and a hole spacing of less than 2.3mm. Row for Orifice Plate Orientation

Its shortcoming is that it is used for the punching and positioning of the microhole array, but it cannot be used for the positioning of the processed microhole array, especially it cannot be used for the equidistant density of the puncture template that has a tooling and cannot be positioned with three stops on one side.
