[0020] In the above structure, the feeding cylinder 9 is installed in the frame 3 and is connected to the extension plate through its push rod, thereby driving the slide 10 to slide along the baffle 7. When the material port 11 on the slide 10 moves to the specified position, a cover plate is allowed to pass through and enter the engraving area; the slide 10 is slidably connected between the two baffles 7, and the material port 11 opened thereon is used to release the raw materials into the laser engraving area one by one; the feeding bin 8 is connected to the top of the baffle 7 and is used to store the cover plate raw materials to be processed. These raw materials can be stacked for continuous feeding; the holding cylinder 13 is connected to the bottom of the frame 12, and its push rod passes through the bottom wall of the frame 12 and is connected to the holding plate 14. Through the telescopic movement of the cylinder, the holding cylinder 13 is connected to the bottom of the frame 12, realizing the up and down movement of the holding plate 14, completing the downward movement of the cover plate.

[0021] In this embodiment, a touch sensor 16 is provided between the two baffles 7 , the engaging groove 15 is located between the touch sensor 16 and the loading bin 8 , and the touch sensor 16 is connected to the PLC controller 4 via a wire.

[0022] With the above structure, the touch sensor 16 can automatically trigger the laser machine to run when the slider 10 moves to the specified position, avoiding safety problems caused by manual misoperation. The touch sensor 16 ensures that the slider 10 stops at the correct position, providing a more accurate positioning basis for subsequent laser engraving, further improving the engraving accuracy.

[0023] In this embodiment, a baffle frame 17 is connected to the baffle bar 7, and a slot 18 adapted to the loading bin 8 is provided on the baffle frame 17.

[0024] With the above structure, the provision of the retaining frame 17 enhances the connection stability between the loading bin 8 and the retaining bar 7, reducing the risk of displacement or disengagement due to vibration or external forces. The retaining frame 17 is connected to the loading bin 8 via the retaining slot 18, which simplifies the installation process and also facilitates subsequent maintenance or replacement.

[0025] In this embodiment, a protective cover 19 is provided on the outer wall of the frame 3 , and the extension plate is slidably connected in the protective cover 19 .

[0026] The above structure can prevent workers from coming into contact with the moving slide bar 10, thereby achieving the technical purpose of protecting workers and avoiding potential safety hazards.

[0029] In this embodiment, an adjustment slot 22 adapted to the baffle frame 17 is formed on the baffle bar 7 .

[0030] The above-described structure and the design of the adjustment slot 22 provide greater installation and adjustment flexibility. By adjusting the position of the retaining frame 17 within the adjustment slot 22, the relative position between the loading bin 8 and the frame 3 can be fine-tuned to accommodate cover plates of different sizes or shapes. This design makes the continuous loading and unloading mechanism more versatile and adaptable.

[0031] Initial state: the holding plate 14 is located in the engagement groove 15 .

[0032] Working principle: the cover plate in the loading bin 8 falls into the material port 11, and the loading cylinder 9 drives the slide bar 10 to move toward the laser machine 1 through the extension plate. The end of the slide bar 10 contacts the touch sensor 16, and the PLC controller 4 laser machine 1 runs to perform laser engraving on the surface of the cover plate. After the laser engraving is completed, the holding cylinder 13 drives the holding plate 14 to drop to the height of a cover plate. At this time, the cover plate in the material port 11 falls on the lowered holding plate 14, and the loading cylinder 9 drives the slide bar 10 to move away from the laser machine 1 (the material port 11 moves to the bottom of the loading bin 8). The above steps are repeated to complete the continuous loading and unloading of the cover plate.

[0033] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
