A pipe port is arranged in the trough body to communicate with an external cooling water circulation supply system. The fine carving platform can move between a silo mechanism and a fine carving mechanism in a straight line direction in the trough body. A loading and unloading manipulator is arranged above the fine carving platform. When working, each silo of the silo mechanism is loaded with glass pieces to be finely carved according to a certain proportion. Both sides of the loading and unloading manipulator are provided with vacuum suction ports. The vacuum suction port on one side is rotated to a vertical direction to place the finely carved glass piece in an idle position of the silo, and the vacuum suction port on the other side takes out the glass piece to be finely carved in the silo, and after the glass piece is rotated to a horizontal direction, it abuts against the inner wall of an L-shaped positioning block arranged on the side of the silo support plate, and the silo mechanism drives the L-shaped positioning block to close the inner wall of the L-shaped positioning block.

[0027] The present invention is innovatively designed with a silo mechanism for storing and taking out glass sheets. The silo mechanism uses a horizontally arranged silo support plate as a supporting component, and a plurality of silos of box-like structures are evenly spaced on the silo support plate. Limit bars are correspondingly provided on both sides of the interior of the silo, and limit tooth grooves are evenly spaced on the limit bars, forming an insertion space between the two set limit tooth grooves; the sheet-shaped glass sheets are vertically inserted into the insertion space, and are clamped and limited by the limit tooth grooves; in the fine carving process, after the silo is loaded, some space is left at one end of the silo, and the material taking robot of the fine carving machine takes out the glass sheets from the other end of the trough. After the fine carving is completed, the glass sheets are inserted into the idle space at one end of the silo until all the glass sheets in the silo are filled. The glass pieces are all finished after fine carving; this glass piece storage method greatly increases the storage quantity of glass pieces, and the vertical insertion method is convenient for taking and placing glass pieces, which is beneficial to reducing the time of taking and placing materials; in addition, the silo mechanism is evenly spaced with at least two L-shaped correction blocks on one side of the silo support plate corresponding to the silo. After the manipulator absorbs the glass piece, it rotates it to the horizontal direction and presses the glass piece against the two vertical side walls on one side of the L-shaped correction block; the correction cylinder arranged under the silo support plate drives the overall movement of the silo support plate, and the position and angle of the glass piece in the horizontal direction are limited and corrected through the side wall of the L-shaped correction block to ensure the subsequent fine carving accuracy.

[0028] In addition, the loading and unloading robot is innovatively designed to realize the automated material picking and delivery of glass sheets. The loading and unloading robot is fixed with a rack of a strip structure on a bracket, and a gap is left between the rack and the top of the bracket, and a transmission wheel is embedded in the gap space, and the transmission wheel and the rack are meshingly connected; and the transmission wheel is connected to the rack motor arranged above the linear module through a transmission belt. When the rack motor drives the transmission wheel to rotate through the transmission belt, the reaction force of the rack to the transmission wheel drives the gear to drive the entire linear module to slide back and forth in a straight line along the direction of the first slide rail arranged on the bracket; through this kind of rack-driven structural design, the accuracy of the linear module during the linear motion process is effectively guaranteed, and it is guaranteed that the vacuum suction nozzle can accurately take out the glass sheet from the material box of the engraving machine and place the taken out glass sheet on the engraving platform for processing; at the same time, the innovative design of the loading and unloading robot has support The tube serves as a supporting bearing structure, and the supporting tube is arranged in a direction perpendicular to the first slide rail, and a plurality of suction seats are evenly spaced thereon, and a plurality of vacuum suction nozzles are respectively arranged on the upper and lower sides of each suction seat; during fine carving, the vacuum suction nozzle on one side of the suction seat takes out the glass piece to be finely carved from the material box of the fine carving machine, and when the supporting seat moves to the fine carving platform, the supporting tube drives the plurality of suction seats to rotate 180° as a whole, so that the vacant vacuum suction nozzle on the other side of the suction seat faces downward, and the glass piece that has been finely carved on the fine carving platform is removed; at this time, the supporting tube is rotated again by a certain angle, so that the air holes arranged thereon are aligned with the fine carving platform, and the high-pressure gas discharged through the air holes blows out the residue remaining on the fine carving platform due to the fine carving of the previous glass piece to the outside of the fine carving platform, and then the supporting tube is rotated again by a certain angle, so that one side of the suction seat faces downward, so that the glass piece to be finely carved can be placed on the cleaned fine carving platform for the next fine carving action.

[0068] Furthermore, the present invention designs a structure of a rotating gear and a fixedly arranged bar-shaped rack meshing with the gear, and utilizes the reaction force of the rack when the gear rotates to drive the gear to move linearly, thereby effectively improving the accuracy of the linear motion, and utilizes the upper and lower double vacuum suction nozzles design, and realizes the switching of the double vacuum suction nozzles by the rotation of the support tube, so that the vacuum suction nozzle can absorb the glass pieces to be finely carved or have been finely carved; and through the air hole design on the support tube, the fine carving platform is cleared of residues by high-pressure gas before placing a new glass piece, and the centralized and large-scale storage of glass pieces is realized by vertical insertion, and the classified and interval storage of glass pieces before and after fine carving is realized, and it has the function of limiting and orienting, and completes the positioning of the glass pieces while taking the material, effectively ensuring the quality of the automatic fine carving machine and its fine carving process. The present invention is based on a precision carving platform, which is arranged in a trough body of a machine platform. A pipe port is arranged in the trough body to communicate with an external cooling water circulation supply system. The precision carving platform can move between a silo mechanism and a precision carving mechanism in a straight line direction in the trough body. A loading and unloading manipulator is arranged above the precision carving platform. When working, each silo of the silo mechanism is loaded with glass pieces to be precision carved according to a certain proportion. Both sides of the loading and unloading manipulator are provided with vacuum suction ports. The vacuum suction port on one side is rotated to a vertical direction to place the precision-carved glass piece in an idle position in the silo, and the vacuum suction port on the other side takes out the glass piece to be precision-carved in the silo, and after the glass piece is rotated to a horizontal direction, it is pressed against the inner wall of an L-shaped positioning block arranged on the side of the silo support plate. The silo mechanism completes the correction of the glass piece by driving the L-shaped positioning block to stick to the glass piece. Action; after the glass piece is calibrated, the loading and unloading manipulator moves to the top of the fine carving platform and rotates 180° so that the vacant vacuum suction hole can absorb the finely carved glass piece from the fine carving platform; after the glass piece on the fine carving platform is taken out, the supporting tube of the loading and unloading manipulator rotates a certain angle so that the air hole opened on it is downwardly aligned with the fine carving platform, and high-pressure gas is sprayed to clean up the residue and the like remaining on the fine carving platform; after the fine carving platform is cleaned, the supporting tube rotates again so that the glass piece to be finely carved faces horizontally downward, and the supporting tube places the glass piece on the fine carving platform for the next fine carving action; this cycle is repeated until the glass pieces to be finely carved in multiple parallel silos are synchronously finely carved; specifically: the present invention is ingeniously designed with a silo mechanism for the storage and placement of glass pieces.The silo mechanism uses a horizontally arranged silo support plate as a supporting component, and a plurality of box-shaped silos are evenly spaced on the silo support plate. Limit bars are correspondingly provided on both sides of the interior of the silo, and limit tooth grooves are evenly spaced on the limit bars, forming an insertion space between the two limit tooth grooves; the sheet-shaped glass pieces are vertically inserted into the insertion space, and are clamped and limited by the limit tooth grooves; in the fine carving process, after the silo is loaded, some space is left at one end of the silo, and the material taking manipulator of the fine carving machine takes out the glass piece from the other end of the trough. After the fine carving is completed, the glass piece is inserted into the idle space at one end of the silo until all the glass pieces in the silo are The glass pieces are all finished after fine carving; this glass piece storage method greatly increases the storage quantity of glass pieces, and the vertical insertion method is convenient for taking and placing glass pieces, which is beneficial to reducing the time of taking and placing materials; in addition, the silo mechanism is evenly spaced with at least two L-shaped correction blocks on one side of the silo support plate corresponding to the silo.

In addition, the loading and unloading robot is innovatively designed to realize the automated material picking and delivery of glass sheets. The loading and unloading robot is fixed with a rack of a strip structure on a bracket, and a gap is left between the rack and the top of the bracket, and a transmission wheel is embedded in the gap space, and the transmission wheel and the rack are meshingly connected; and the transmission wheel is connected to the rack motor arranged above the linear module through a transmission belt. When the rack motor drives the transmission wheel to rotate through the transmission belt, the reaction force of the rack to the transmission wheel drives the gear to drive the entire linear module to slide back and forth in a straight line along the direction of the first slide rail arranged on the bracket; through this kind of rack-driven structural design, the accuracy of the linear module during the linear motion process is effectively guaranteed, and it is guaranteed that the vacuum suction nozzle can accurately take out the glass sheet from the material box of the engraving machine and place the taken out glass sheet on the engraving platform for processing; at the same time, the innovative design of the loading and unloading robot has support The tube serves as a supporting bearing structure, and the supporting tube is arranged in a direction perpendicular to the first slide rail, and a plurality of suction seats are evenly spaced thereon, and a plurality of vacuum suction nozzles are respectively arranged on the upper and lower sides of each suction seat; during fine carving, the vacuum suction nozzle on one side of the suction seat takes out the glass piece to be finely carved from the material box of the fine carving machine, and when the supporting seat moves to the fine carving platform, the supporting tube drives the plurality of suction seats to rotate 180° as a whole, so that the vacant vacuum suction nozzle on the other side of the suction seat faces downward, and the glass piece that has been finely carved on the fine carving platform is removed; at this time, the supporting tube is rotated again by a certain angle, so that the air holes arranged thereon are aligned with the fine carving platform, and the high-pressure gas discharged through the air holes blows out the residue remaining on the fine carving platform due to the fine carving of the previous glass piece to the outside of the fine carving platform, and then the supporting tube is rotated again by a certain angle, so that one side of the suction seat faces downward, so that the glass piece to be finely carved can be placed on the cleaned fine carving platform for the next fine carving action.

At the same time, the vacuum suction port on the other side of the suction seat inserts the taken carved glass piece into the limit tooth groove reserved in the silo; S3, positioning correction: After the loading and unloading manipulator takes out the glass piece to be carved in step S2, it rotates 90 degrees to rotate the glass piece to the horizontal direction, and the loading and unloading manipulator moves the horizontal glass piece and makes it close to the L-shaped correction block of the bin mechanism; the correction cylinder of the bin mechanism drives the L-shaped correction block to move linearly to correct the position angle of the glass piece; S4, second material removal: After the position of the glass piece to be fine-carved is corrected in step S3, the loading and unloading manipulator moves to the fine-carving platform, the suction seat rotates 180°, so that the vacuum suction hole on the other side of the suction seat faces downward, and the fine-carved glass piece is taken out from the fine-carving platform; S5, platform cleaning: After the glass piece on the fine carving platform is taken out in step S4, the support tube of the loading and unloading manipulator rotates so that the air holes arranged at intervals thereon are arranged toward the fine carving platform, and the high-pressure gas ejected from the air holes cleans the fine carving platform; S6, second discharge: after the engraving platform in step S5 is cleaned, the suction seat in step S4 is rotated 180 degrees, so that the glass piece to be engraved adsorbed by the vacuum suction hole on one side of the suction seat faces downward, and is placed on the cleaned engraving platform; S7, platform sliding: after the glass sheet is placed on the fine carving platform in step S6, the fine carving platform slides linearly to the bottom of the fine carving mechanism; S8, fine carving: After the fine carving platform in step S7 slides to the bottom of the fine carving mechanism, the fine carving mechanism approaches the glass sheet so as to finely carve and polish the glass sheet.
