[0042] When using:

[0043] The glass product is transferred from the left side to the right side of the marking workbench 1 by the conveyor belt 2. When the glass comes to the bottom of the vertical movable frame 1 9 and the vertical movable frame 2 10, the sensor 17 senses the arrival of the glass, and then starts the suction pump 302 through the controller (not shown). The suction pump 302 extracts the etching paste loaded in the supply barrel 301, and sends it to the needle 14 through the conductive hose 15, and then it can be discharged to the non-pattern area of ​​the glass (i.e., the top edge of the glass) through the needle 14. When there is etching paste on the glass, since the main component of the glass is SIO2, the etching paste will react with the SIO2 of the glass to carve a concave pit morphology on the glass, thereby achieving the purpose of marking. The marked glass then passes through the lighting device 4, and the reaction speed of the material is accelerated by the irradiation of the lighting lamp 402. Finally, it can pass through the water washing section (not shown) set on the other side of the marking workbench 1. After washing, traces that are convenient for identification can be revealed, so that mixing of goods can be avoided.

[0044] When the needle 14 needs to be cleaned, the staff can place the bottom outlet of the needle 14 in the supporting frame 501, and use the sponge block 502 in the supporting frame 501 to wipe the bottom of the needle 14, thereby achieving the purpose of cleaning and reducing the possibility of clogging of the needle 14.

[0045] It should be noted that when the longitudinal position of the longitudinal movable frame 1 7 or the longitudinal movable frame 2 8 needs to be adjusted, the staff only needs to start the servo motor of the driving structure 1 6, so that the servo motor drives the screw connected thereto to rotate, and the rotation of the screw can drive the longitudinal movable frame 1 7 or the longitudinal movable frame 2 8 to move longitudinally on the top of the marking workbench 1;

[0046] When it is necessary to adjust the height of the vertical movable frame 1 9 or the vertical movable frame 2 10, the staff only needs to start the servo motor of the driving structure 2 11, so that the servo motor drives the screw connected thereto to rotate, and when the screw on the longitudinal movable frame 1 7 rotates, the vertical movable frame 1 9 can be driven to move vertically on the longitudinal movable frame 1 7, and when the screw on the longitudinal movable frame 2 8 rotates, the vertical movable frame 2 10 can be driven to move vertically on the longitudinal movable frame 2 8;

[0047] When the lateral position of the needle 14 or the sensor 17 needs to be adjusted, the staff only needs to start the servo motor of the driving structure three 12, so that the servo motor drives the screw connected thereto to rotate. When the screw in the vertical movable frame one 9 rotates, it can drive the movable block one 13 to move, thereby driving the needle 14 to move. When the screw in the vertical movable frame two 10 rotates, it can drive the electric movable block two 16 to move, thereby driving the sensor 17 to move.

[0048] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
