Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, and in particular to a multifunctional cutting, marking and splitting machine. Background Technology

[0002] Laser cutting and marking is a non-contact processing method. A laser is focused on metals and hard, brittle materials, creating longitudinal and transverse burst points through thermal melting. This alters the molecular bonds of the material, forming cutting or marking lines. Laser cleaving of hard, brittle materials involves heating the outer ring of the cut path after laser cutting the desired closed shape, or heating the outer area of ​​the cut path in the hard, brittle material, or heating both the outer and inner ring areas while cooling the inner ring area. This allows the crack formed by the cutting to penetrate the material.

[0003] The cutting and marking of existing metals and hard and brittle materials, as well as the fracturing of hard and brittle materials, usually require multiple steps on different processing equipment. These steps are numerous and require transfer between different machines, making the process quite cumbersome. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model designs a multi-functional cutting, marking and splitting integrated machine.

[0005] The present invention adopts the following technical solution: A multifunctional cutting, marking, and splitting integrated machine includes a frame, a green laser, a CO2 laser, a collimator, a 3D scanning galvanometer, a field lens, a beam expander, an optical path converter, a focusing lens, and a workpiece motion platform. The output end of the green laser is connected to the collimator, which in turn connects to the 3D scanning galvanometer. A field lens is installed at the lower output end of the 3D scanning galvanometer, and the workpiece motion platform is correspondingly positioned below the field lens. The output end of the CO2 laser is connected to the beam expander, which in turn connects to the optical path converter. The output end of the optical path converter is connected to the focusing lens, and the workpiece motion platform is positioned below the focusing lens.

[0006] Preferably, the frame includes an optical path support frame and a motion platform support frame. A green laser, a CO2 laser, a collimator, and a beam expander are fixedly installed on the optical path support frame, and a workpiece motion platform is fixedly installed on the motion platform support frame.

[0007] Preferably, the workpiece motion platform includes a motion platform and a workpiece positioning platform.

[0008] Preferably, the motion platform includes an X-axis slide and a Y-axis slide, with the Y-axis slide mounted on the X-axis slide and the workpiece positioning platform mounted on the Y-axis slide.

[0009] Preferably, the workpiece positioning platform is a vacuum adsorption platform.

[0010] Preferably, the focusing lens is installed directly below the output end of the optical path deflector, and a Z-axis slide is installed on the optical path support frame. The focusing lens is installed on the Z-axis slide, and the Z-axis slide controls the focusing lens to move up and down to adjust the focusing.

[0011] Preferably, the green laser and the CO2 laser are installed side by side in parallel.

[0012] The beneficial effects of this invention are as follows: The laser emitted from a green laser is collimated and then scanned by a 3D scanning galvanometer through a field lens to perform 3D scanning processing on the workpiece. This enables marking and cutting of hard and brittle materials. The 3D scanning galvanometer allows for processing at different heights, eliminating the need for Z-axis laser focus control. After cutting, the hard and brittle workpiece can be re-illuminated along the cutting path by a CO2 laser beam that has been expanded, refocused, and then split through laser thermal effects. Marking, cutting, and splitting can be completed in a single loading operation, saving costs and increasing production efficiency. Attached Figure Description

The output end of the green laser is connected to the collimator, which in turn connects to the 3D scanning galvanometer. A field lens is installed at the lower output end of the 3D scanning galvanometer, and the workpiece motion platform is correspondingly located below the field lens. The output end of the CO2 laser is connected to the beam expander, which in turn connects to the optical path converter. The output end of the optical path converter is connected to the focusing lens, and the workpiece motion platform is located below the focusing lens.

The motion platform drives the workpiece on the workpiece positioning platform to move in the X and Y directions, so as to simultaneously complete the three processes of marking, cutting, and splitting.

This enables marking and cutting of hard and brittle materials. The 3D scanning galvanometer allows for processing at different heights, eliminating the need for Z-axis laser focus control. After cutting, the hard and brittle workpiece can be re-illuminated along the cutting path by a CO2 laser beam that has been expanded, refocused, and deflected, resulting in flaking through laser thermal effects.
