[0034] During the process, the conveying operation of the glass substrate is completed by the first conveying roller 2 in the conveying cavity 1. Before the detection, the first conveying roller 2 is driven by the first driving component 3 to automatically convey. While conveying, the conveyed glass is cleaned by the cleaning component 4, and the cleaning liquid is discharged by the discharge component 8, so that impurities on the glass can be effectively removed, the accuracy of subsequent thickness detection can be ensured, and the error can be reduced. The lifting component 5 is coordinated with the cleaning component 4 to achieve real-time adjustment of the height of the cleaning component 4 to meet the operation requirements of glass of different thicknesses.

As the driving shaft 33 rotates, the bevel gear set 34 can be driven to enter a driving state, prompting the bevel gear set 34 to drive the shaft end of the first conveying roller 2 to rotate, thereby synchronously driving the first conveying roller 2 to rotate, prompting the first conveying roller 2 to enter a conveying state.

[0043] In this embodiment, the lifting assembly 5 includes a first telescopic cylinder 51, a fixed frame 52, and a fixed plate 53.

[0044] During this period, when the components in the installation cover 41 enter the operation, the first telescopic cylinder 51 is first started to drive the installation cover 41 to be raised and lowered, so that the components in the installation cover 41 are in line with the thickness of the conveyed glass substrate, ensuring that the glass substrate can receive the required cleaning operation.

[0045] In this embodiment, the cleaning component 42 includes a second spray rod 421, a second rubber scraper 422, and a second conveying roller 423.

[0047] During this process, the cleaning liquid is sprayed on the glass substrate by the nozzle on the liquid spray rod 421, and then the cleaning roller in a rolling state is used for cleaning, and finally the liquid stains on the glass substrate are scraped off by the rubber scraper.

[0048] Embodiment 3

[0049] like Figure 1-Figure 7 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0050] In this embodiment, the detection component 62 includes a first installation cavity 621, a laser detector 622, a second motor 623, a guide rail 624, a mounting bracket 625, a rack 626, a disk gear 627, and a carrier plate 628. The driving end of the flip component 63 is docked with the first installation cavity 621, and three groups of carrier plates 628 are slidably installed inside the first installation cavity 621 through the guide rail 624. The bottom of the carrier plate 628 is fixedly installed with a mounting bracket 625, and the top of the mounting bracket 625 is fixedly installed with a second motor 623. The output end of the second motor 623 is docked with a disk gear 627, and the inner wall of the first installation cavity 621 is fixedly installed with a rack 626, and the rack 626 and the disk gear 627 are meshed with each other. A laser detector 622 is fixedly installed on one side of the mounting bracket 625.

[0051] During this period, when the glass substrate is conveyed to the bottom of the detection component 62, the second motor 623 can be started, and the output end of the second motor 623 drives the disc gear 627 to rotate. Under the driving cooperation of the disc gear 627 and the rack 626, the real-time movement of the mounting bracket 625 is realized, so as to adjust the position of the laser detector 622 to meet the required detection points and sizes of the glass substrate, and the six laser detectors 622 in the two groups of first mounting cavities 621 can simultaneously perform thickness detection on six locations of the glass substrate to ensure the thickness control of the glass substrate after production.

[0052] In this embodiment, the flip assembly 63 includes a second mounting shell 631, a driving gear set 632, a third motor 633, a first rotating shaft 634, a connecting head 635, and a second rotating shaft 636.

[0053] By combining the above contents, when personnel need to maintain or overhaul the detection component 62, it can be achieved by flipping the component 63;

[0054] During this period, the third motor 633 is started, and the output end of the third motor 633 first drives the second rotating shaft 636 to rotate. At that time, a transmission relationship is generated between the driving gear set 632 on the second rotating shaft 636 and the first rotating shaft 634, prompting the first rotating shaft 634 to rotate synchronously. In this way, the first rotating shaft 634 will drive the first installation cavity 621 to rotate through the connecting head 635, thereby realizing the flipping of the first installation cavity 621. After the flipping of the first installation cavity 621, its internal components will be displayed to the outside, and personnel will perform corresponding operations.

[0055] In this embodiment, the moving component 72 includes an electric screw 721, a guide seat 722, and a second installation cavity 723.

[0056] During the process, when the thickness of the detected glass substrate deviates, the extraction component 73 can be started to extract the abnormal glass substrate. After the extraction, the electric screw 721 can be started, and the electric screw 721 drives the guide seat 722 to move linearly, so that the guide seat 722 synchronously drives the extraction component 73 to move linearly, so that the extracted abnormal glass substrate can be moved out of the detection station.

The output end of the second telescopic cylinder 731 passes through the foot plate 732 and is docked with an adsorption plate 734. Suction cups 733 are evenly distributed on the bottom of the adsorption plate 734.

[0058] By combining the above contents, during the period, when the detected thickness of the glass substrate deviates, the second telescopic cylinder 731 can be started, and the second telescopic cylinder 731 drives the adsorption plate 734 to descend, prompting the suction cup 733 on the adsorption plate 734 to adsorb the glass substrate, thereby realizing the lifting operation of the glass substrate, and finally cooperating with the extraction component 73 to complete the real-time movement of the glass substrate and move the glass substrate out of the working station.

[0059] In this embodiment, the drainage assembly 8 includes a blocking bar 81, a drainage pipe 82, and a drainage cavity 83. The bottom of the conveying cavity 1 is docked with a connected drainage cavity 83, and the bottom of the drainage cavity 83 is docked with a connected drainage pipe 82. Two groups of blocking bars 81 are fixedly installed on the top of the conveying cavity 1, and the blocking bars 81 are located on both sides of the port of the drainage cavity 83.

[0060] During the cleaning operation, due to the generation of cleaning liquid, it will be retained at the bottom of the conveying cavity 1, and then the cleaning liquid will be blocked by the blocking bar 81 and enter the drainage cavity 83, and finally it can be discharged uniformly to the outside through the drainage pipe 82 at the bottom of the drainage cavity 83.
