Description

Technical Field

[0001] The present application relates to the technical field of diamond processing, and in particular to a galvanometer coaxial scanning three-dimensional contour recognition and laser processing diamond forming device. Background Art

[0002] Diamond is widely used in high-precision fields such as optics, electronics and machinery due to its ultra-high hardness and excellent physical properties. However, traditional diamond processing methods, such as mechanical polishing, face many challenges. These methods are not only time-consuming and costly, but also cause great wear on the tools due to the high hardness of diamond, resulting in low processing efficiency. In addition, mechanical processing is also prone to leaving tiny cracks and defects on the surface of diamond, affecting the final performance of the material.

[0003] In order to overcome these difficulties, laser processing technology has been introduced into diamond processing. The equipment commonly used in laser processing is the galvanometer system, which has the advantages of non-contact, no wear, fast processing speed, and high precision, and is particularly suitable for processing high-hardness materials. However, relying solely on laser processing still has some limitations when processing complex surface morphologies. For example, it is difficult for workers to find the point where the laser irradiates the diamond surface, resulting in low processing accuracy. Summary of the invention

[0005] In order to solve the technical problems mentioned in the above background technology part, some embodiments of the present application provide a galvanometer coaxial scanning three-dimensional contour recognition and laser processing diamond forming device, including: a galvanometer system, an integrated main frequency beam splitter, the galvanometer system forms a laser processing light path, and the laser processing light path passes through the main frequency beam splitter; a first convex lens, the first convex lens faces the main frequency beam splitter; a pinhole plate, forming a pinhole coaxial with the central axis of the first convex lens; a detector, forming a detection end facing the pinhole.

[0006] Furthermore, the galvanometer system also includes: a laser generator, an oscillating mirror and a second convex lens; the laser generator emits laser, which passes through the oscillating mirror and the main frequency beam splitter in sequence and is emitted from the second convex lens to form the laser processing optical path.

[0007] Furthermore, the main frequency beam splitter comprises: a beam splitter lens and a first driving member; an output end of the first driving member is fixed to the beam splitter lens, and the first driving member causes the beam splitter lens to rotate around an axis parallel to the ground.

[0008] Furthermore, the swing mirror comprises: a plane mirror and a second driving member; an output end of the second driving member is fixed to the plane mirror, and the second driving member causes the plane mirror to rotate around an axis perpendicular to the ground.

[0009] Furthermore, the laser generator can emit picosecond laser, nanosecond laser and continuous laser.

[0010] Furthermore, a scanning light path is formed from the diamond surface through the second convex lens, the beam splitter lens, the first convex lens and the pinhole plate to the detector.

[0011] The beneficial effects of this application are:

[0012] The laser emitted by the galvanometer system is irradiated on a point on the diamond surface through the laser processing optical path. The light reflected from a point on the diamond surface is emitted from the main frequency beam splitter through part of the laser processing optical path, and enters the detector through the first convex lens and the pinhole plate. The point where the laser is irradiated on the diamond surface is located, thereby identifying the area to be processed and obtaining its morphological information. The galvanometer system then controls the laser to process the identified area on the diamond surface, and accurately adjusts the laser processing parameters according to the morphological information of each processing position to achieve high processing accuracy.

[0026] A galvanometer coaxial scanning three-dimensional contour recognition and laser processing diamond forming device includes: a galvanometer system, a first convex lens 5, a pinhole plate 6 and a detector 7. A main frequency beam splitter 1 is integrated in the galvanometer system, and the main frequency beam splitter 1 is a common component in this field. A laser processing optical path is formed in the galvanometer system, and the laser processing optical path passes through the main frequency beam splitter 1. The laser emitted along the laser processing optical path processes the diamond surface. The laser is a picosecond laser, a nanosecond laser or a continuous laser. The first convex lens 5 faces the main frequency beam splitter 1, and the pinhole plate 6 forms a pinhole coaxial with the central axis of the first convex lens 5. The detector 7 faces the pinhole to form a detection end. The main frequency beam splitter 1, the first convex lens 5, the pinhole plate 6 and the detector 7 cooperate with some components in the galvanometer system to form a confocal microscope system. The confocal microscope system is a common technical concept in this field. When workers use the device, the confocal microscope system first uses a single-beam galvanometer to scan. The light on the surface of the diamond passes through the first convex lens 5 and the pinhole plate 6 and is finally received by the detection end of the detector 7. The detector 7 then identifies the three-dimensional contour of the diamond and obtains its morphological information. The workers adjust the laser parameters, such as laser power, pulse width and scanning speed, to ensure the accuracy of diamond processing.

[0027] Specifically, the galvanometer system further includes: a laser generator 2, a swing mirror 3 and a second convex lens 4. The main frequency beam splitter 1 includes: a beam splitter lens 11 and a first driver 12. The first driver 12 is a first motor, the output end of the first driver 12 is fixed to the beam splitter lens 11, and the first driver 12 rotates the beam splitter lens 11 around an axis parallel to the ground. The swing mirror 3 includes: a plane mirror 31 and a second driver 32. The second driver 32 is a second motor, the output end of the second driver 32 is fixed to the plane mirror 31, and the second driver 32 rotates the plane mirror 31 around an axis perpendicular to the ground. The laser generator 2 emits a laser, and the laser passes through the swing mirror 3 and the main frequency beam splitter 1 in sequence and is emitted from the second convex lens 4 to form a laser processing optical path. When it is necessary to change the irradiation position of the laser on the diamond surface, the first driver 12 rotates the beam splitter lens 11. As the angle of the beam splitter lens 11 relative to the diamond surface changes, the laser moves in a straight line on the diamond surface after being reflected from the surface of the beam splitter lens 11. The second driving member 32 rotates the plane mirror 31. The laser is reflected by the plane mirror 31 and the beam splitter lens 11 and moves along another straight line on the diamond surface. The two moving paths are perpendicular to each other, so that the laser can process the entire surface of the diamond.

[0028] Specifically, the diamond surface forms a scanning light path through the second convex lens 4, the beam splitter lens 11, the first convex lens 5 and the pinhole plate 6 to the detector 7, and the light on the diamond surface is irradiated into the detector 7 through the scanning light path, so that the detector 7 can identify the contours avoided by the diamond.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
