Description

Technical Field

[0001] The utility model relates to the technical field of laser engraving, in particular to a laser engraving machine with an adjustment structure. Background Art

[0002] A laser engraving machine is a professional device that uses laser technology to engrave, cut or mark the surface of various materials. Its basic working principle is that the laser engraving machine focuses a high-energy laser beam through a laser engraving spray gun and irradiates the surface of the material. The thermal effect of the laser causes the material to melt, evaporate or ablate rapidly. At the same time, the movement path and power of the laser beam are precisely controlled by a computer control system to achieve fine engraving or cutting of the material.

[0003] The patent with publication number CN218050848U discloses a laser engraving machine, which includes a transverse plate, a circular table at the bottom of the transverse plate, a plurality of electromagnets arranged in a circle inserted in the circular table, a connecting rod rotatably connected to the bottom of the circular table, magnets embedded at both ends of the connecting rod, an adjustment sleeve nested at the bottom of the connecting rod, linearly arranged electromagnets inserted in the adjustment sleeve, and a laser engraving spray gun inserted at the bottom of the adjustment sleeve. When the electromagnets in the circular table are all working, the multiple magnetic forces exerted on the connecting rod make the connecting rod reach a balanced state. When the angle of the connecting rod needs to be adjusted, only one of them needs to be adjusted. When one or more electromagnets are powered off, the magnetic force acting on the connecting rod changes, making it impossible for the connecting rod to maintain balance, causing the angle of the connecting rod to deflect. The engraving angle can then be changed. However, direct contact between the electromagnet and the magnet can easily lead to demagnetization of the magnet. Furthermore, long-term operation of the electromagnet can cause the temperature of the metal coil inside the electromagnet to rise, thereby increasing the resistance of the electromagnet and reducing its magnetism. Therefore, the magnetism of the electromagnet is difficult to control, and errors can easily occur when adjusting the deflection angle of the connecting rod, resulting in deviations in the engraving accuracy.

[0022] It should be noted that the side wall of the inner cavity of the base 2 is provided with serrations, which are arranged circumferentially with the central axis of the base 2 as the axis. The base 2 is also provided with a plurality of slots 8 arranged relatively to each other, and a cover plate 6 is inserted into the plurality of slots 8. The cover plate 6 is provided with a slide groove 2 7 with an arc-shaped horizontal cross-section. The slide groove 2 7 is slidably connected to the mounting frame 4, and the shape of the slide groove 2 7 is the same as the motion trajectory of the mounting frame 4.

[0023] like Figure 3 、 Figure 4As shown, the mounting frame 4 is generally bow-shaped, and a through slot 401 is provided in the mounting frame 4. A serrated groove 402 is provided on the side wall of the through slot 401, and a slide groove 403 corresponding to the groove 402 is provided on the other side wall of the through slot 401. The positioning component 5 is engaged with the groove 402, and the positioning component 5 is slidably connected to the slide groove 403.

[0024] like Figure 1 and Figure 2 As shown, the rotating assembly 3 includes a plurality of driven wheels 301, the top ends of the plurality of driven wheels 301 are rotatably connected to the bottom end of the mounting frame 4 via bearings, and the plurality of driven wheels 301 are all engaged with the side walls of the inner cavity of the base 2, and the bottom wall of the inner cavity of the base 2 is rotatably connected to a driving wheel 1 302 that is engaged with the plurality of driven wheels 301, and a driving member that drives the driving wheel 1 302 to rotate is detachably connected to the base 2;

[0025] It should be noted that when the laser engraving gun 1 is needed to engrave the object, the drive motor 303 is started, and the drive motor 303 drives the driving wheel 1 302 to rotate, and the driving wheel 1 302 is engaged with the two driven wheels 301, and the two driven wheels 301 are engaged with the side walls of the inner cavity of the base 2. When the driving wheel 1 302 rotates, it drives the two driven wheels 301 to rotate along the side walls of the inner cavity of the base 2, and the rotation direction of the two driven wheels 301 in the base 2 is the same as the rotation direction of the driving wheel 1 302.

[0026] like Figure 3 and Figure 4 As shown, the positioning assembly 5 includes a slider 501, a second driving wheel 502 is rotatably connected to the slider 501, and the second driving wheel 502 is engaged with the side wall of the groove 1 402. The top of the slider 501 is detachably connected to a servo motor 503 that drives the second driving wheel 502 to rotate;

[0027] It should be noted that when the angle of the laser engraving spray gun 1 needs to be adjusted, the servo motor 503 is first started, and the servo motor 503 drives the active wheel 2 502 to rotate, and the active wheel 2 502 engages with the serrated groove 1 402 on the side wall of the through groove 401, thereby driving the slider 501 to slide on the mounting bracket 4.

When the angle needs to be adjusted, the servo motor 503 is started, and the servo motor 503 drives the active wheel 2 502 to rotate. The active wheel 2 502 engages with the serrations in the groove 1 402, so that the slider 501 slides on the mounting bracket 4, thereby achieving angle adjustment in the vertical plane. Then the drive motor 303 is started, and the drive motor 303 drives the active wheel 1 302 to rotate. The active wheel 1 302 in turn drives the two driven wheels 301 to rotate around the active wheel. The top ends of the two driven wheels 301 are respectively connected to the two ends of the mounting bracket 4 for rotation, thereby preventing the device from getting stuck during the rotation process.
