Leveling mechanisms in related technologies rely on complex motors or sensors, resulting in high costs and slow response times. Utility Model Content

Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0016] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0017] The technical solution adopted by this utility model to solve its technical problem is: like Figures 1 to 2As shown in the figure, some embodiments of this utility model disclose a laser etching device, which includes a base frame 10, a lifting assembly 20, a laser etching assembly 30, an adjustment platform assembly 40, and a sensor assembly 50. The lifting assembly 20 is vertically mounted on the base frame 10 for vertical movement. The laser etching assembly 30 is mounted on the lifting assembly 20 and moves up and down with it, allowing for height adjustment via the lifting assembly 20 and laser etching of the workpiece. The adjustment platform assembly 40 is located between the base frame 10 and the laser etching assembly 30, and the workpiece is placed on the adjustment platform assembly 40 for leveling its upper surface. The sensor assembly 50 is mounted on the lifting assembly 20 for verifying the position of the laser etching assembly 30. The adjustment platform assembly 40 of this laser etching device is adjustable to accommodate irregular or tilted workpieces, avoiding complex visual focusing algorithms. Instead of primarily adjusting the laser etching assembly 30, the non-adjustable tool is used as the adjustment target, resulting in high efficiency and low error.

[0018] For reference Figure 3 The adjustment platform assembly 40 includes a spherical gear 41, a lower platform 42, an upper platform assembly 43, and a gear limiting assembly 44. The base frame 10 is provided with a spherical groove 110 (please refer to...). Figure 5 A spherical gear 41 is rotatably mounted within a spherical groove 110, allowing it to rotate 360 ​​degrees within the groove. A lower platform 42 is mounted on the spherical gear 41, supporting the workpiece and rotating with it to adjust its angle. An upper platform assembly 43 is mounted on the lifting assembly 20, moving vertically to fit against the upper surface of the workpiece, thus horizontally restricting its movement. The upper platform assembly 43 is parallel to the laser etching assembly 30, allowing for horizontal adjustment of the workpiece's upper surface. Essentially, when the workpiece is placed on the lower platform 42, the lifting assembly 20 drives the upper platform assembly 43 downwards to contact any point on the workpiece surface. At this point, the workpiece's upper surface is not yet horizontal. Manually rotating the lower platform 42, i.e., rotating the spherical gear 41 within the spherical groove 110, causes the lower platform 42 to adjust the workpiece. When the workpiece's upper surface fits against the upper platform assembly 43, it indicates that the workpiece's upper surface is now horizontal.

[0019] It should be noted that spherical gears can be divided into spherical involute gears, spherical cycloidal gears, and spherical circular arc gears. Through the design of a "metal sphere + double saddle gears," spherical gears achieve unrestricted 360-degree rotation, simplifying the structure and reducing weight, and are widely used in fields such as robot joints. The spherical gear 41 in this laser etching equipment is a hemispherical gear 41, or rather, half of a spherical gear.

[0020] Refer again Figure 3In some embodiments, the upper platform assembly 43 may include a fixed block 431, a rotating shaft 432, and an upper platform 433. The fixed block 431 is mounted on the lifting assembly 20, the rotating shaft 432 is vertically mounted on the fixed block 431, and the upper platform 433 is rotatably mounted on the rotating shaft 432 to rotate to one side after workpiece adjustment. Understandably, the upper platform 433 moves up and down with the lifting assembly 20 via the fixed block 431. When the workpiece is placed on the lower platform 42, the lifting assembly 20 drives the upper platform 433 to move downwards, causing it to fit against any point on the upper surface of the workpiece. The rotating shaft 432 moves up and down on the fixed block 431, driving the upper platform 433 to move up and down, allowing the upper platform 433 to move slightly up and down after contacting the workpiece. The upper platform 433 is rotatably mounted on the rotating shaft 432 via a bushing. When the workpiece is adjusted to a horizontal state, the upper platform 433 can be rotated to one side so that the laser etching component 30 suspended above the workpiece can perform laser etching on the upper surface of the workpiece, so as to avoid blocking the laser etching path of the laser etching component 30.

[0021] Continue to refer to Figure 3 In some embodiments, the upper platform component 43 may also include at least one level 434 disposed on the upper platform 433 to detect whether the upper platform 433 (or the upper surface of the workpiece) is level.

[0022] In other embodiments, the upper platform 433 has a hollow structure in the middle. The upper platform 433 is attached to the edge of the workpiece and can also be used to horizontally limit the upper surface of the workpiece. The laser etching component 30 can perform laser etching on the upper surface of the workpiece through the hollow structure.

[0023] like Figure 4 and Figure 5 As shown, in some embodiments, the gear limiting assembly 44 may include a lifting drive 441, a tooth 442, and a connecting rod 443. The lifting drive 441 is mounted on the base frame 10, the connecting rod 443 is hinged to the output end of the lifting drive 441, and the tooth 442 is mounted on the connecting rod 443. The tooth 442 engages or disengages with the spherical gear 41 under the drive of the lifting drive 441. Understandably, the lifting drive 441 is a cylinder, which drives the connecting rod 443 to move up and down. When the workpiece is adjusted, the cylinder drives the connecting rod 443 to move upward, causing its tooth 442 to contact the spherical gear 41, and the tooth 442 engages with the spherical gear 41 (see reference). Figure 2 The cylinder drives the connecting rod 443 to move downwards, causing its teeth 442 to move away from the spherical gear 41. The teeth 442 disengage from the spherical gear 41, thus enabling the spherical gear 41 to rotate.

[0024] In some embodiments, the gear limiting assembly 44 may also include a control switch that controls the lifting and lowering of the lifting drive 441.

[0025] Refer again Figure 1 In some embodiments, the sensor assembly 50 may include a support plate and at least one proximity sensor 51. The support plate is mounted on the lifting assembly 20, and the proximity sensor 51 is mounted on the support plate, suspended above the laser etching assembly 30 to verify the positional relationship between the laser etching assembly 30 and the workpiece. Two proximity sensors 51 are provided in this laser etching equipment. The proximity sensors 51 may also employ multiple sets of laser rangefinders (such as triangulation) to calculate the Z-axis displacement compensation in real time; combined with preset focal length parameters (such as a working distance of 45mm ± 0.1mm), the laser head position is automatically calibrated.

[0026] The following section will further explain the laser etching equipment in conjunction with its usage.

[0027] When using this laser etching equipment: The workpiece is placed on the lower platform 42. The lifting assembly 20 moves the upper platform 433 downwards, bringing it into contact with the upper surface of the workpiece. The spherical gear 41 is rotated to adjust the angle of the workpiece, ensuring its upper surface is aligned with the horizontal upper platform 433. At this point, the upper surface of the workpiece is horizontal. The lifting drive 441 drives the connecting rod 443 upwards, engaging the teeth 442 with the spherical gear 41 to limit its movement. The upper platform 433 is then rotated to one side of the workpiece. Finally, the laser etching assembly 30 performs laser etching on the upper surface of the workpiece.

[0028] It should be noted that, for those skilled in the art, without departing from the concept of this utility model, the above-mentioned technical features can be freely combined, and several modifications and improvements can be made, all of which fall within the protection scope of this utility model.
