Description

Technical Field

[0001] This utility model relates to the technical field of diamond processing equipment, specifically to an angle adjustment fixture for laser cutting diamonds. Background Technology

[0002] Diamond, with its high hardness, high thermal conductivity, high breakdown electric field, high carrier mobility, and wide bandwidth, is hailed as the ultimate semiconductor and has broad application prospects in numerous fields such as solid-state power devices, heat dissipation devices, optical windows, electrochemical motors, and machining. With the continuous development of technology, the demand for high-quality diamond wafers with specific shapes is increasing, especially in high-end electronics and optics, where standard cuboid diamond wafers are crucial for subsequent growth and application.

[0003] Laser cutting is a crucial process in current diamond crystal production, encompassing the cutting of finished crystals, in-process crystal cutting, and surface finishing. However, the laser cutting process for separating diamond sheets presents numerous challenges due to limitations in the cutting technology. During cutting, laser irradiation induces graphitization on the diamond, which is then ablated and removed by further heating. However, this process, involving graphite and the graphite vapor generated during ablation, causes laser beam deformation and power loss. To improve cutting efficiency, higher laser output power is often used, but this leads to reduced surface quality, consequently affecting crystal growth quality. Furthermore, existing cutting processes often result in trapezoidal diamond sheets, making it impossible to directly obtain standard cuboid diamond sheets. Only standard cuboid diamond sheets are suitable for growth, severely limiting the application and further development of diamond in fields with stringent shape requirements. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a tilt adjustment fixture for laser-cutting diamonds that can clamp diamonds and adjust their tilt angle during the cutting process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tilt angle adjustment fixture for laser cutting diamond, comprising a base, a fixture base plate disposed on the base, a positioning base disposed in the middle of the fixture base plate, a fixture unit disposed on one side of the positioning base plate, and an adjustment unit for adjusting the tilt angle of the fixture base plate disposed on the other side, the end of the fixture base plate facing the fixture unit being connected to the base through a clamping unit, and the other end being connected to the adjustment unit.

[0006] As a further improvement to the above technical solution:

[0007] The adjustment unit includes a mounting base disposed on the side wall of the positioning base, an adjustment motor disposed on the mounting base, a screw penetrating the fixture base plate at the output end of the adjustment motor, and a bearing seat connected to the lower end of the screw disposed on the base.

[0008] A coupling is provided between the screw and the regulating motor.

[0009] The fixture base plate is provided with threaded holes for use with screws.

[0010] The lower surface of the clamping base plate is provided with a slope, and the thickness of the slope gradually decreases as it extends from the clamping unit to the adjustment unit.

[0011] The clamping unit includes multiple mold handles distributed along the length of the positioning base, each mold handle being designed perpendicular to the positioning base.

[0012] The clamping unit includes a fastening screw for connecting the base and the clamping base plate, and a clamping spring is provided on the upper part of the fastening screw located above the clamping base plate.

[0013] The fastening screws are two in number and are symmetrically distributed about the center line of the base, with a horizontal adjustment ball between the two fastening screws.

[0014] The beneficial effects of this utility model embodiment are as follows: The tilt angle adjustment fixture for laser cutting diamond includes a base, a fixture base plate on the base, a vertically designed positioning base in the middle of the fixture base plate, a fixture unit on one side of the positioning base plate, and an adjustment unit for adjusting the tilt angle of the fixture base plate on the other side. One end of the fixture base plate facing the fixture unit is connected to the base through a clamping unit, and the other end is connected to the adjustment unit. The angle of the fixture base plate can be adjusted by the adjustment unit, thereby compensating for the tilt angle of the fixture unit, ensuring that the diamond can be kept in a vertical state, so that a standard cuboid can be obtained after cutting, which is convenient for subsequent production operations.

[0020] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0021] like Figure 1-4 As shown, the tilt angle adjustment fixture for laser cutting diamond in this embodiment includes a base 1, a fixture base 2 on the base 1, a vertically designed positioning base 3 in the middle of the fixture base 2, a fixture unit 4 on one side of the positioning base 3, and an adjustment unit 5 for adjusting the tilt angle of the fixture base 2 on the other side. One end of the fixture base 2 facing the fixture unit 4 is connected to the base 1 through a clamping unit, and the other end is connected to the adjustment unit 5. The angle of the fixture base 2 can be adjusted by the adjustment unit 5, thereby compensating for the tilt angle of the fixture unit 4, ensuring that the diamond can be kept in a vertical state, so that a standard cuboid can be obtained after cutting, which is convenient for subsequent production operations.

[0022] The adjustment unit 5 includes a mounting base 6 installed on the side wall of the positioning base 3. The mounting base 6 is equipped with an adjustment motor 7. The output end of the adjustment motor 7 is equipped with a screw 8 that passes through the clamping base plate 2. The base 1 is equipped with a bearing seat 9 connected to the lower end of the screw 8. The adjustment motor 7 drives the screw 8 to rotate, thereby driving one end of the clamping base plate 2 to move up or down, ultimately achieving the angle adjustment of the diamond, so that the diamond and the cutter are kept perpendicular. In order to detect the adjustment angle, an angle sensor 15 is installed above the positioning base 3 to detect the tilt angle after adjustment.

[0023] A coupling 16 is provided between the screw 8 and the regulating motor 7.

[0024] The fixture base plate 2 is provided with threaded holes that cooperate with the screw 8.

[0025] The lower surface of the clamping base plate 2 is provided with a ramp 10. The ramp 10 extends from the clamping unit 4 to the adjustment unit 5 and the thickness gradually decreases. The design of the ramp 10 can provide avoidance for the longitudinal displacement of the clamping base plate 2.

[0026] The fixture unit 4 includes multiple mold handles 11 distributed along the length of the positioning base 3. Each mold handle 11 is designed perpendicular to the positioning base 3, enabling batch cutting of diamonds.

[0027] The clamping unit includes fastening screws 12 for connecting the base 1 and the clamping base plate 2. A clamping spring 1 is provided on the upper part of the fastening screw 12 and located above the clamping base plate 2. There are two fastening screws 12 and they are symmetrically distributed about the center line of the base 1. A horizontal adjusting ball 14 is provided between the two fastening screws 12.
