[0024] The overall process flow of the present invention includes: S1. Stock storage: The glass sheets to be processed are stacked in the rack; S2. Material taking: The material taking component takes out the glass sheets in step S1 from the rack and blows the sheets; S3. Material placing: The material taking component in step S2 sequentially places the taken-out glass sheets on the sheet conveying component; S4. Material discharging: One side of the loading and unloading component synchronously adsorbs multiple glass sheets from the sheet conveying component, turns them 180°, and places the finely carved glass sheets adsorbed on the other side on the sheet conveying component; S5. Material loading: The loading and unloading component in step S3 moves above the fine carving carrier, adsorbs the finely carved glass sheets from the fine carving carrier, turns them 180°, and places the adsorbed glass sheets to be finely carved on the fine carving carrier, and cycles the loading and unloading in this way; S6.

Glass sheet transfer: The sheet transmission component in step S6 conveys the finely carved glass sheets to the transfer component, and the transfer component transfers them to the next processing station.

[0025] The present invention is designed with a rack and a material taking component. The rack uses a limiting plate slidably arranged on the material seat as a limiting component. Multiple limiting plates form a sheet placing space with adjustable width and length for stacking multiple glass sheets to be processed vertically. The material taking component arranged on the side of the rack takes out the stacked glass sheets from the rack by means of vacuum adsorption. At the same time, high-pressure gas is blown out from the side of the blowing nozzle on the side of the material taking suction nozzle of the material taking component to blow away the multiple glass sheets adhered together during material taking, avoiding the situation of sticking sheets.

[0026] The present invention is designed with a sheet conveying component. The sheet conveying component uses the first conveying rail and the second conveying rail arranged in parallel at intervals as the bearing components. The same-direction tensioning wheels are arranged inside the two conveying rails to tension the conveyor belts. The tensioning wheels between the two conveyor belts are connected by a connecting roller shaft. The glass sheets taken out by the material taking component are placed on the two conveyor belts. The conveying motor arranged outside the conveying rail drives the connecting roller shaft to rotate through the transmission teeth, and drives the two conveyor belts to move linearly synchronously through the connecting roller shaft to convey the glass sheets forward. Particularly, the first conveying rail and the second conveying rail of the present invention are arranged on the bracket and are slidably connected to the cylindrical guide rail arranged on the bracket. This structural design enables the first conveying rail and the second conveying rail to adjust the spacing in real time according to the width of the conveyed glass sheets, and the spacing is fixed by rotating and pressing the fixing cap after adjustment.

[0027] The present invention is designed with a loading and unloading component for synchronously taking out multiple glass sheets to be finely carved, synchronously taking out the finely carved glass sheets on multiple fine carving carriers, placing the glass sheets to be finely carved on the vacant fine carving carriers, and at the same time, putting the finely carved glass sheets back onto the sheet conveying component and conveying them to the next working station through the sheet conveying component. To achieve the above functions, the loading and unloading component of the present invention uses a horizontally arranged flipping support rod as the support carrier. The flipping support rod rotates through the drive of a flipping motor. At the position corresponding to the fine carving carrier on the flipping support rod, multiple suction seats are arranged in parallel at intervals. The inside of the suction seat is a gas chamber structure, and multiple unloading suction nozzles are respectively arranged on the front and back sides of the suction seat. During operation, the flipping support rod drives the multiple suction seats to rotate synchronously, so that one side of the suction seat sucks the glass sheets to be finely carved on the sheet conveying component. The linear module drives the whole flipping support rod to linearly move to the position of the fine carving carrier. The flipping support rod rotates 180° so that the unloading suction nozzles on the other side of the suction seat suck the finely carved glass sheets from the fine carving carrier. The linear module drives the whole flipping support rod to linearly move back to the sheet transmission component. The unloading suction nozzles on the other side of the flipping support rod put the processed glass sheets back onto the sheet conveying component and then adsorb the glass sheets to be processed from the sheet conveying component. In this way, the automatic back-and-forth cyclic transfer of the glass sheets between the sheet conveying component and the fine carving carrier is realized through repeated cycles.

Unloading: One side of the loading and unloading component synchronously adsorbs multiple glass sheets from the sheet material conveying component, turns 180°, and places the engraved glass sheets adsorbed on the other side on the sheet material conveying component; S5. Loading: In step S3, the loading and unloading component moves above the engraving carrier, adsorbs the engraved glass sheets from the engraving carrier, turns 180°, and places the glass sheets to be engraved adsorbed on the engraving carrier, and circulates the loading and unloading in this way; S6.

Glass sheet transfer: In step S6, the sheet material transmission component conveys the engraved glass sheets to the transfer component, and the transfer component transfers them to the next processing station. The present invention designs a material rack and a material taking component.

The material taking component arranged on the side of the material rack takes out the stacked glass sheets from the material rack by means of vacuum adsorption. At the same time, high-pressure gas is blown out from the side of the material taking nozzle of the material taking component through the blowing nozzle on the side to blow away the multiple glass sheets adhered together during material taking to avoid the occurrence of sheet sticking. The present invention designs a sheet material conveying component. The sheet material conveying component uses the first conveying rail strip and the second conveying rail strip arranged in parallel at intervals as the bearing components. The inner sides of the two conveying rail strips are tensioned with conveyor belts in the same direction through tensioning wheels, and the tensioning wheels between the two conveyor belts are connected by connecting roller shafts. The glass sheets taken out by the material taking component are placed on the two conveyor belts. The conveying motor arranged outside the conveying rail strip drives the connecting roller shaft to rotate through the transmission gear, and drives the two conveyor belts to move synchronously in a straight line through the connecting roller shaft to convey the glass sheets forward. In particular, the first conveying rail strip and the second conveying rail strip of the present invention are arranged on the bracket and are slidably connected to the cylindrical guide rail arranged on the bracket. This structural design enables the first conveying rail strip and the second conveying rail strip to adjust the distance in real time according to the width of the conveyed glass sheets, and the distance is fixed by rotating and pressing the fixing cap after adjustment.The present invention is designed with a loading and unloading component for synchronously taking out multiple glass sheets to be finely carved, synchronously taking out the finely carved glass sheets on multiple fine carving carriers, placing the glass sheets to be finely carved on the vacant fine carving carriers, and at the same time putting the finely carved glass sheets back onto the sheet conveying component and conveying them to the next workstation through the sheet conveying component. To achieve the above functions, the loading and unloading component of the present invention uses a horizontally arranged flipping support rod as the support carrier. The flipping support rod is driven by a flipping motor to rotate. At the position corresponding to the fine carving carrier on the flipping support rod, a plurality of suction seats are arranged in parallel at intervals. The inside of the suction seat is a gas cavity structure, and a plurality of unloading suction nozzles are respectively arranged on the front and back sides of the suction seat. During operation, the flipping support rod drives the plurality of suction seats to rotate synchronously, so that one side of the suction seat sucks the glass sheets to be finely carved on the sheet conveying component. The linear module drives the whole flipping support rod to linearly move to the position of the fine carving carrier. The flipping support rod rotates 180° so that the unloading suction nozzles on the other side of the suction seat suck the finely carved glass sheets from the fine carving carrier. The linear module drives the whole flipping support rod to linearly move back to the sheet transmission component.
