[0032] The XY-axis motion mechanism includes a frame-shaped motion support 110, an X-axis motion module 120, and a Y-axis motion module 330. The motion support 110 and the control panel 900 are both fixedly installed within the support frame 300. The touch switch 700 is installed on the top of the motion support 110.

The X-axis slide rail 121 slides through the X-axis guide slots 1221, and both ends of the X-axis slide rail 121 are fixed to the two Y-axis sliders 131. The X-axis motion seat 122 has X-axis motor mounting holes (not shown) that extend vertically through it on the front or rear side of the X-axis guide slots 1221. The X-axis drive motor 126 is mounted on... The top of the X-axis motion seat 122 is connected to the drive wheel 124 via the X-axis motor mounting hole. The driven wheel 125 is rotatably connected to the bottom of the X-axis motion seat 122 outside the drive wheel 124. The two ends of the X-axis moving wheel 123 are fixed to the two Y-axis sliders 131, and the X-axis moving wheel 123 winds through the drive wheel 124 and the driven wheel 125. The laser 800 is fixedly mounted to the side wall of the X-axis motion seat 122, and the laser head of the laser 800 extends below the support frame 300.

[0037] Specifically, the XY axis motion mechanism of the engraving machine further includes a first locking screw 140 and a second locking screw 145. A U-shaped connecting groove 1312 is provided on one side of the Y-axis slider 131 near the X-axis motion seat 122. One end of the U-shaped connecting groove 1312 is a tire winding inlet 13121, and the other end is a tire winding outlet 13122. A tire release is provided on the outside of the tire winding outlet 13122, communicating with the tire winding outlet 13122. A notch 13123 is provided. The Y-axis slider 131 has a first locking screw hole (not shown) between the tire winding inlet 13121 and the tire winding outlet 13122. The first locking screw hole communicates with the U-shaped connecting groove 1312. One end of the X-axis moving tire 123 winds into the U-shaped connecting groove 1312 from the tire winding inlet 13121 and out from the tire winding outlet 13122. The first locking screw 140 is screwed in and inserted through the first locking screw hole to press the X-axis moving tire 123. A transition slope or a transition arc surface is provided at the junction of the tire placement notch 13123 and the U-shaped connecting groove 1312. Another Y-axis slider 131 has a left-right oriented access groove 1313 and a fixing groove 1314 perpendicularly connected to the access groove 1313 at one end near the X-axis motion seat 122. A second locking screw hole (not shown) is provided on the inner side wall of the Y-axis slider 131 opposite the fixing groove. The other end of the X-axis moving belt 123 extends from the access groove 1313 and then bends into the fixing groove 1314. The second locking screw 145 screws through the second locking screw hole and presses against the X-axis moving belt 123. When the X-axis motion seat 122 moves towards the belt exit 13122 and collides with the X-axis moving belt 123, the end of the X-axis moving belt 123 bends and moves into the belt placement notch 13123, effectively preventing the X-axis motion seat 122 from deviating from its predetermined movement trajectory due to the collision with the X-axis moving belt 123.

[0038] Preferably, the Y-axis motion module 130 further includes an upper transition roller 139. The upper transition roller 139 is rotatably connected to the bottom of the transverse mounting block 112, and the upper transmission belt 1342 is wound around the upper transition roller 139.

[0039] When the XY axis motion mechanism is working, the Y-axis drive motor starts and drives the upper drive wheel 1341 to rotate, which in turn drives the lower drive wheel 1351 to rotate, thereby causing the two upper drive belts 1342 and the lower drive belt 1352 to rotate synchronously and move, thereby causing the two Y-axis sliders 131 to move forward or backward synchronously; the X-axis drive motor 126 starts and drives the belt drive wheel 124, which in turn drives the belt driven wheel 125 to roll, thereby causing the belt drive wheel 124 and the belt driven wheel 125 to roll left and right on the X-axis moving belt 123, thereby causing the X-axis moving seat 122 to move left and right.

[0040] When using this desktop engraving machine, manually open the protective cover 400 upwards. The touch switch 700 is touched by the touch toggle arm 600, and the control panel 900 receives the open cover signal, thereby stopping the laser 800 from working. After placing the workpiece on the base 200 and fixing it in place, manually close the protective cover 400 downwards. The touch switch 700 is touched by the touch toggle arm 600 again, and the control panel 900 receives the close cover signal, thereby starting the laser 800 from working.

[0041] The protective cover of this desktop engraving machine is rotatably connected to the support frame. When the protective cover is opened, the friction between the protective cover and the support frame bracket supports the protective cover, thus preventing it from tipping over. At the same time, the protective cover can be opened or closed flexibly by hand, making it more convenient and practical to use. In addition, when the protective cover is opened or closed, a touch switch is activated by a touch control arm to transmit a signal to the control panel, thereby controlling whether the laser is stopped or not. The structure is ingenious and practical.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
