[0031] In this embodiment, the first processing line 1, the second processing line 2, the third processing line 3 and the fourth processing line 4 are arranged in sequence along the direction of glass travel, and the first processing line 1 is connected to the second processing line 2 via the pre-tempering conveyor line 5, the second processing line 2 is connected to the third processing line 3 via the pre-screening conveyor line 6, and the fourth processing line 4 is connected to the third processing line 3. This design, using the pre-tempering conveyor line 5 and the pre-screening conveyor line 6, ensures seamless connection between each process and realizes standardization and continuity of the glass production process. Compared with traditional glass production lines, the automatic glass production line provided by the utility model greatly reduces manual intervention and waiting time, improves overall production efficiency, avoids production delays caused by waiting or transportation, and further improves production efficiency. At the same time, it also reduces errors caused by human factors, such as dimensional deviation, poor processing, etc., and improves the yield and consistency of products.

The automatic feeding and slitting machine 11, the glass striping machine 12, the first glass cornering machine 13, the single chip microcomputer 14 and the front-end sorting machine 15 are arranged in sequence along the direction of glass travel and in an L-shaped arrangement. The first edge grinding and polishing line 16 and the second edge grinding and polishing line 17 are arranged side by side, one end of the first edge grinding and polishing line 16 is connected to a conveying section of the front-end sorting machine 15, the other end of the first edge grinding and polishing line 16 is connected to the head end of the docking line, one end of the second edge grinding and polishing line 17 is connected to the other conveying section of the front-end sorting machine 15 through a conveying line, the other end of the second edge grinding and polishing line 17 is connected to the head end of the docking line through a 90° turning machine 101, the end of the docking line is connected to the drilling machine 18, and a cleaning and drying line is arranged between the drilling machine 18 and the first visual inspection machine 19.

[0033] In this embodiment, the automatic loading and slitting machine 11 is used to grab glass and place the glass at a predetermined position for slitting. The automatic loading and slitting machine 11 can accurately cut large pieces of glass according to preset sizes.

[0034] After the initial cutting of the glass, irregular scraps or excess parts will be left on the edge. The glass striping machine 12 in this embodiment can identify and cut off these scraps to make the glass edges neat and uniform. Through cutting and trimming, the glass striping machine 12 can process the glass plates to a predetermined size and shape, providing standardized glass plates for subsequent processes such as edging, polishing, and drilling, which helps to ensure the consistency of the entire production process and the stability of product quality.

[0035] In this embodiment, through the first glass corner machine 13, the automatic loading and slitting machine 11, the glass striping machine 12, the first glass corner machine 13, the single chip microcomputer 14 and the front-end sorting machine 15 are arranged in sequence along the travel direction of the glass and in an L-shaped arrangement. The glass starts from the automatic loading and slitting machine 11, undergoes slitting and striping processing, and then changes the travel direction through the first glass corner machine 13, and finally enters the single chip microcomputer 14 and the front-end sorting machine 15 for further processing and screening. This layout reduces the distance and time of glass transportation between different equipment, improves overall production efficiency, and makes full use of space resources.

[0036] In this embodiment, the glass sheet sorting machine 14 is used to separate and convey the glass sheets transported from the first glass corner turning machine 13, so that multiple glass sheets can be transported sequentially along two conveying paths. The front-end sorting machine 15 is used to screen the preliminarily processed glass, separating qualified and unqualified glass sheets. The qualified glass sheets are respectively fed into the first edge grinding and polishing line 16 and the second edge grinding and polishing line 17, while the unqualified glass sheets are rejected.

[0037] It should be noted that this embodiment does not involve specific structural improvements to equipment such as the automatic loading and slitting machine 11, the glass striping machine 12, the first glass corner turning machine 13, the single-chip microcomputer 14, the front-end sorting machine 15, the first edge grinding and polishing line 16, the second edge grinding and polishing line 17, the drilling machine 18 and the first visual inspection machine 19.

[0051] It should be noted that this embodiment does not involve specific structural improvements to equipment such as dust blowers, silk screen machines, chain ovens, cooling axial fans, dust blowers, silk screen machines, etc. Therefore, this embodiment does not elaborate on the specific structures of these devices. Those skilled in the art can select corresponding equipment from the existing technology and assemble and match them according to the connection method and arrangement method provided in the embodiment of this application to form a third processing line 3 for realizing silk screen processing on glass.
