Technical Field
[0001] The utility model belongs to the technical field of positioning jigs, and in particular relates to a laser engraving positioning jig. Background Art
[0002] Traditional computer keyboard keys currently sold on the market are very convenient to use in bright environments. However, in dark environments, the operator cannot see the words and symbols on the keyboard clearly and cannot operate flexibly, which affects the normal use of the computer keyboard. Therefore, current keyboards generally have backlights and are used with laser engraving technology to engrave the letters on the keyboard keys. When the keyboard backlight is on, the letters light up, making the keys in the keyboard clearer and cooler. However, the existing laser engraving process is to place the keyboard on a workbench and then use a laser beam to engrave the keyboard. During this process, the keyboard and the laser generator remain perpendicular, so the engraved letters lack a sense of three-dimensionality. Utility Model Content

[0020] In one embodiment of the present invention, reference Figures 1 and 2 As shown, a laser engraving positioning jig is provided, comprising a fixed base 10 and a fixed plate 20. The fixed plate 20 is used to place a keyboard and is disposed on the fixed base 10. The fixed base 10 comprises a fixed base 11, two positioning plates 12, and a rotating support plate 13. The two positioning plates 12 are parallel to each other and perpendicular to the fixed base 11. One side of the positioning plate 12 is arc-shaped. The fixed plate 20 is disposed at the arc-shaped end of the positioning plate 12. One end of the rotating support plate 13 is rotatably connected to the positioning plate 12, and the other end is connected to the fixed plate 20. In this embodiment, the fixed base 11 is placed on a workbench, parallel to the workbench. After the operator grasps the fixed plate 20 by hand, the operator drives the selected support plate to rotate, thereby driving the fixed plate 20 to rotate, so that a certain angle is formed between the fixed base 11 and the fixed plate 20. Then, a laser generator is used to engrave the keyboard on the fixed plate 20, so that the beam emitted by the laser emitter also forms a certain angle with the keyboard, thereby increasing the three-dimensional effect of the engraved keys.
[0021] Specifically, refer to Figures 1 and 2 As shown, the positioning plate 12 is further provided with a plurality of angle adjustment holes 14, and one side of the rotating support plate 13 is snapped into the angle adjustment hole 14. In this embodiment, the angle adjustment holes 14 are also distributed in an arc shape on the positioning plate 12. After the rotating support plate 13 is snapped into the angle adjustment hole 14, the position of the rotating support plate 13 can be fixed, thereby preventing the position of the positioning plate 12 from changing during the laser engraving process, which would result in uneven engraving results.
[0022] Specifically, refer to Figures 1 and 2As shown, a handle 21 is further provided on one side of the fixing plate 20. In this embodiment, after the operator holds the handle 21 with his hand, it is more convenient to adjust the rotating support plate 13 and the operation is more convenient.
[0023] Specifically, refer to Figures 1 and 2 As shown, the keyboard also includes a fixed cover plate 30, one end of which is hinged to one end of the fixed plate 20 via a hinge. The fixed cover plate 30 is also provided with a number of airtight holes 32 corresponding to the keyboard. In this embodiment, the fixed cover plate 30 is opened, the keyboard is placed on the fixed plate 20, and the fixed cover plate 30 is rotated so that the keyboard is positioned between the fixed cover plate 30 and the fixed plate 20. The keycaps on the keyboard pass through the airtight holes 32, allowing the laser emitter to laser engrave the keycaps normally. At the same time, the fixed cover plate 30 and the fixed plate 20 limit the keyboard to prevent the fixed plate 20 from tilting too much and causing the keyboard position to change during the laser engraving process.
[0024] Specifically, refer to Figures 1 and 2 As shown, the fixed cover plate 30 is further provided with a hook 33 at the end away from the hinge, and a loop 34 is provided on the back of the fixed plate 20 to match the hook 33. The hook 33 and loop 34 cooperate with each other to secure the fixed cover plate 30. In this embodiment, the hook 33 and loop 34 cooperate to secure the fixed cover plate 30, making the keyboard position more secure.
[0025] Specifically, refer to Figures 1 and 2 As shown, the fixing plate 20 is further provided with a plurality of exhaust holes 22, each of which penetrates the fixing plate 20. In this embodiment, the fixing plate 20 is further provided with a plurality of exhaust holes 22, each of which penetrates the fixing plate 20, to prevent air from being trapped between the keyboard and the fixing plate 20 when the keyboard is placed on the fixing plate 20, thereby preventing the keyboard from changing its shape.
[0026] Specifically, refer to Figures 1 and 2 As shown, the fixed base plate 11 is further provided with a plurality of positioning holes 15, each positioning hole 15 passes through the fixed base plate 11. In this embodiment, the positioning holes 15 are used to position the fixed base plate 11 on the workbench to prevent the position of the fixed base plate 11 from changing during the work process, thereby affecting the laser engraving accuracy.
[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
