Detailed implementation manners

[0022] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0023] A screening device for screening different cover plate substrates, referring to Figure 1 , includes a detection assembly line 10 and cover plate substrates 20 to be detected transported on the detection assembly line 10. A conveyor belt 30 is arranged along the length direction on the detection assembly line 10, and a plurality of cover plate substrates 20 to be detected are transported along the length direction on the conveyor belt 30. One end of the conveyor belt 30 is the feeding end 31 and the other end is the discharging end 32. The cover plate substrates 20 are transported from the feeding end 31 of the conveyor belt 30 to the discharging end 32.

[0024] Referring to Figure 1 , a glass surface stress meter 40 and a chromaticity tester 50 for detecting the type of the cover plate substrate 20 are arranged along the length direction on the detection assembly line 10. Among them, the glass surface stress meter 40 is located at the feeding end 31 of the conveyor belt 30, and the glass surface stress meter 40 is embedded in the detection assembly line 10 to detect the cover plate substrate 20 located above. The cover plate substrate 20 entering the detection assembly line 10 is first transported to the glass surface stress meter 40 for detection. The glass surface stress meter 40 will match the tempered layer distribution map of the detected cover plate substrate 20 with the tempered layer distribution map in the database, so as to judge which cover plate substrate 20 it is. The tempered layer distribution maps corresponding to different cover plate substrates 20 are input into the database of the glass surface stress meter 40 in advance.

[0025] Referring to Figure 1After being detected by the glass surface stress meter 40, the cover plate substrate 20 is transported along the length direction of the detection pipeline 10 to the chromaticity tester 50. The chromaticity tester 50 is fixed on one side of the detection pipeline 10, and the chromaticity tester 50 faces the side of the cover plate substrate 20 to perform chromaticity testing on the side of the cover plate substrate 20. The detection port 51 of the chromaticity tester 50 is located on the side of the chromaticity tester 50 facing the detection pipeline 10, and the height of the detection port 51 of the chromaticity tester 50 is adapted to the height of the cover plate substrate 20 to perform side chromaticity testing on the cover plate substrate 20 reaching the chromaticity tester 50, and then match the chromaticity corresponding to different cover plate substrates 20 to screen out the type of the cover plate substrate 20.

[0026] Refer to Figure 1 The glass surface stress meter 40 and the chromaticity tester 50 perform two screening detections on the cover plate substrate 20 to quickly judge the type of the cover plate substrate 20 and avoid misjudgment.

[0027] Further, refer to Figure 1 On one side of the chromaticity tester 50, there is a sensor 60 for detecting whether the cover plate substrate 20 reaches the specified detection position. The sensor 60 is fixed on the side of the chromaticity tester 50, and the sensing probe of the sensor 60 faces the detection pipeline 10. The sensor 60 is located on the side of the chromaticity tester 50 away from the feeding end 31. When the sensor 60 senses that one side of the cover plate substrate 20 reaches the specified position, the chromaticity tester 50 can start the detection work.

[0028] Refer to Figure 1 and Figure 2 The detection pipeline 10 includes a first-stage pipeline 11, a second-stage pipeline 12, and a lifting pipeline 13 arranged between the first-stage pipeline 11 and the second-stage pipeline 12. Both ends of the lifting pipeline 13 are connected to the first-stage pipeline 11 and the second-stage pipeline 12 respectively. The lifting pipeline 13 is used to separate different cover plate substrates 20 from the detection pipeline 10. The detection pipeline 10 separates the cover plate substrates 20 and transports the required cover plate substrates 20 for production to the next working station, while the lifting pipeline 13 separates the cover plate substrates 20 that are not required for this production.

[0029] Refer to Figure 1 and Figure 2 Below the second-stage pipeline 12, there is a non-required substrate pipeline 70. The non-required substrate pipeline 70 is arranged in parallel with the second-stage pipeline 12, and one end of the non-required substrate pipeline 70 is flush with one end of the second-stage pipeline 12. One end of the lifting pipeline 13 facing the second-stage pipeline 12 can be lowered to be connected to one end of the non-required substrate pipeline 70 to transport the non-required cover plate substrates 20 to the non-required substrate pipeline 70.

[0030] Reference Figure 1 and Figure 2 , a lifting cylinder 80 for controlling the lifting of the lifting pipeline 13 is arranged below the lifting pipeline 13, and a fixing seat 90 for fixing the lifting cylinder 80 is arranged below the lifting pipeline 13. The bottom of the lifting cylinder 80 is fixed on the fixing seat 90, and the piston rod of the lifting cylinder 80 is connected upward to the bottom of the lifting pipeline 13. The lifting cylinder 80 is used to control the lifting of the lifting pipeline 13 to be connected with the second-stage pipeline 12 and the non-desired substrate pipeline 70 respectively. When both the glass surface stress meter 40 and the chromaticity tester 50 detect that the same cover substrate 20 is not the substrate required for this production, the cover substrate 20 is transported to the lifting pipeline 13, and the lifting cylinder 80 controls the lifting pipeline 13 to descend and connect with the non-desired substrate pipeline 70, so that the cover substrate 20 is transported along the non-desired substrate pipeline 70 to a designated position for storage. By arranging the glass surface stress meter 40 and the chromaticity tester 50 to conduct double detection on the cover substrate 20, this screening device can quickly determine the type of the cover substrate 20, avoid misjudgment, and separate the non-desired cover substrate 20, enabling the cover substrate 20 required for production to reach the designated production position, thereby improving the production efficiency.

[0031] Further, referring to Figure 1 and Figure 2 , a controller 100 is arranged on one side of the detection pipeline 10. The glass surface stress meter 40, the inductor 60, the chromaticity tester 50, and the lifting cylinder 80 are all electrically connected to the controller 100. The controller 100 receives the detection results of the glass surface stress meter 40 and the chromaticity tester 50, and controls the lifting cylinder 80 to lower the non-desired cover substrate 20 onto the non-desired substrate pipeline 70.

[0032] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
