[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0018] Reference Figures 1-5 As shown, this utility model discloses a keyboard chassis laser engraving fixture, comprising: A substrate 1 has a first fixing groove 11 and a second fixing groove 12 extending through its surface. The first fixing groove 11 is arranged along the length axis of the substrate 1, and the second fixing groove 12 is arranged along the width axis of the substrate 1. The pressing part 2 includes a plurality of first magnets 21, which are distributed on one side of the surface of the substrate 1. The first magnets 21 are embedded in the substrate 1 and the surface of the first magnets 21 is flush with the surface of the substrate 1. A second magnet 22 is attached to the top of each first magnet 21.

[0019] In this invention, one side of the substrate 1 is connected to the laser engraving worktable, and the other side is used to place the product 4. Specifically, a first fixing groove 11 is formed along the length direction (X-axis) and a second fixing groove 12 is formed along the width direction (Y-axis) on the surface of the substrate 1. The first fixing groove 11 and the second fixing groove 12 are used to fix the substrate 1. In the actual assembly process, bolts are passed through the first fixing groove 11 and the second fixing groove 12 to connect the substrate 1 to the laser engraving worktable. In the actual processing process, the position of the laser engraving head is fixed. If the processing area of ​​the product 4 is large, laser engraving of different areas can be achieved by adjusting the position of the substrate 1. During the adjustment process, the bolts in one direction can be fixed while the bolts in the other direction are adjusted to ensure the accuracy of the adjustment position.

[0020] Multiple first magnets 21 are distributed on the entire substrate 1, as shown in the figure. Figures 3-4As shown, when product 4 is bonded to substrate 1, product 4 is placed on substrate 1, and then a second magnet 22 is placed on top of product 4. The first magnet 21 and the second magnet 22 press product 4 firmly onto the surface of substrate 1. In actual operation, the second magnet 22 is reasonably distributed according to the size of product 4, avoiding the laser engraving area while ensuring that the laser engraving area of ​​product 4 is completely bonded to substrate 1, thereby ensuring the flatness of the laser engraving area of ​​product 4, reducing the defect rate and labor costs. In addition, the position of the second magnet 22 can be flexibly adjusted according to the laser engraving area of ​​product 4 to avoid affecting the normal laser engraving operation.

[0021] This invention uses a first magnet 21 embedded in the surface of a substrate 1 and a second magnet 22 to press the product 4 firmly onto the substrate 1. This ensures that the laser-engraved area of ​​the product 4 is completely aligned with the substrate 1, guaranteeing the flatness of the laser-engraved area and reducing the occurrence of defective products and wasted time. Furthermore, the first fixing groove 11 and the second fixing groove 12 on the surface of the substrate 1 allow for precise adjustment of the fixture position, enabling the laser engraving of the entire product 4 to be completed in one operation, ensuring laser engraving accuracy while improving production efficiency.

[0022] Furthermore, referring to Figure 5 As shown, the surface of the substrate 1 is provided with at least two positioning holes 14, and a positioning pin 3 is provided in the positioning hole 14; the positioning pin 3 is detachably connected to the positioning hole 14.

[0023] Specifically, in the actual processing, the surface of product 4 is provided with limiting holes that cooperate with positioning pins 3. At least two positioning pins 3 can limit the position of product 4 to prevent product 4 from shaking during laser engraving and affecting the accuracy of laser engraving. Preferably, the positioning pins 3 and the positioning holes 14 are connected by plug-in or threaded connection. Different products 4 have different sizes and their positioning points are also different. In actual operation, the corresponding positioning hole 14 is selected according to different products 4.

[0024] Furthermore, referring to Figure 5 As shown, the surface of the substrate 1 has a plurality of mounting holes 13, and the first magnet 21 is embedded in the mounting holes 13. The depth of the mounting holes 13 is less than the thickness of the substrate 1, and the height of the first magnet 21 is the same as the depth of the mounting holes 13.

[0025] Specifically, in this invention, the mounting hole 13 is a blind hole, and the first magnet 21 is embedded in the mounting hole 13. To avoid the installation of the first magnet 21 affecting the flatness of the product 4, the height of the first magnet 21 is consistent with the depth of the mounting hole 13, and the surface of the first magnet 21 is flush with the surface of the substrate 1. Preferably, the first magnet 21 and the second magnet 22 in this invention can be made of strong magnetic materials, which can also be used to press the thicker product 4.

[0026] Furthermore, the diameter of the first magnet 21 is equal to the diameter of the mounting hole 13; the first magnet 21 and the mounting hole 13 are tightly fitted together, and the first magnet 21 and the mounting hole 13 are bonded together with glue.

[0027] Specifically, during the actual assembly process, the first magnet 21 is interference-fitted with the mounting hole 13, fixing the first magnet 21 within the mounting hole 13. To ensure the stability of the first magnet 21, it can be bonded to the mounting hole 13 with adhesive. The mounting hole 13 is a blind hole, allowing multiple surfaces of the first magnet 21 to contact and bond with the mounting hole 13, further improving the installation stability of the first magnet 21.

[0028] Furthermore, referring to Figure 6 As shown, countersunk grooves 16 are provided at the ports of the first fixing groove 11 and the second fixing groove 12.

[0029] Specifically, the entire substrate 1 is connected to the laser engraving platform by bolts during fixing. The bolts pass through the first fixing groove 11 and the second fixing groove 12, and the nuts are hidden in the countersunk groove 16 to prevent the nuts from protruding and affecting the adhesion between the product 4 and the substrate 1.

[0030] Furthermore, referring to Figure 5 As shown, the substrate 1 has notches 15 on both sides along the width direction, and the notches 15 penetrate the substrate 1.

[0031] Specifically, notches 15 are provided on both sides of the substrate 1 in the width direction to facilitate the separation of the laser-engraved product 4 from the substrate 1 and to remove the product 4 from the substrate 1.

[0032] A keyboard chassis laser engraving device includes the keyboard chassis laser engraving fixture described in the above embodiments.

[0033] In summary, this utility model introduces a keyboard chassis laser engraving fixture and equipment. By embedding a first magnet 21 on the surface of a substrate 1 and using a second magnet 22 to press the product 4 firmly onto the substrate 1, the laser engraving area of ​​the product 4 can be completely fitted to the substrate 1, ensuring the flatness of the laser engraving area and reducing the occurrence of defective products and wasted time. Furthermore, the first fixing groove 11 and the second fixing groove 12 on the surface of the substrate 1 can precisely adjust the position of the fixture, completing the laser engraving of the entire product 4 in one operation, ensuring laser engraving accuracy while improving production efficiency.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description.
