Description

Technical Field

[0002] The soda-based glass cover plate, also known as the sodium-calcium float glass cover plate, is widely used in the field of display protection cover plates due to its low cost advantage. However, its production process adopts the float process, resulting in the two sides of the glass cover plate being the tin surface and the air surface respectively, and there are differences between the tin surface and the air surface. During the production process of the glass cover plate, Sn ions will inevitably penetrate into the glass surface layer, resulting in microscopic defects such as impurities and voids on the tin surface layer of the glass cover plate. These defects will cause appearance defects in subsequent ink screen printing or surface coating.

[0003] In the prior art, some customers require ink screen printing and surface coating to be done on the air surface of the glass cover plate (the air surface has high surface smoothness), which requires production to control and distinguish the tin surface and the air surface of the glass. After the glass cover plate is cut into single pieces by CNC, due to its transparent appearance, it is difficult to effectively distinguish the tin surface and the air surface, and it is difficult to ensure ink screen printing and coating on the air surface of the glass cover plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order 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.

[0024] A device for distinguishing the tin surface and air surface of a soda-based tempered glass cover plate, refer to Figure 1, including a transportation assembly line 10 and a glass cover plate 20 to be detected transported onto the transportation assembly line 10. A conveyor belt 30 is arranged along the length direction on the transportation assembly line 10. The glass cover plate 20 is located on the conveyor belt 30, and the glass cover plate 20 is arranged along the length direction of the conveyor belt 30. One end of the conveyor belt 30 is a feeding end 31 and the other end is a discharging end 32. The feeding end 31 of the conveyor belt 30 is the place where the glass cover plate 20 starts to be transported, and the discharging end 32 of the conveyor belt 30 transports to an ink screen printing station. The conveyor belt 30 transports the glass cover plate 20 from the feeding end 31 to the discharging end 32 direction.

[0025] Refer to Figure 1 , a detection device for detecting whether the upper surface of the glass cover plate 20 is a tin surface or an air surface is arranged on the transportation assembly line 10. The detection device is fixed on the side of the transportation assembly line 10 to detect the glass cover plate 20 transported on the transportation assembly line 10.

[0026] Refer to Figure 1 , during the production process of the glass cover plate 20, Sn ions will inevitably penetrate into the surface layer of the glass cover plate 20, resulting in microscopic defects such as impurities and voids on the tin surface layer of the glass cover plate 20. These defects will cause appearance defects in the subsequent ink screen printing or surface coating. It is required that the ink screen printing and surface coating be done on the air surface of the glass cover plate 20. Therefore, it is necessary to detect whether the air surface side of the glass cover plate 20 on the transportation assembly line 10 is placed upwards, and the detection device is used to detect whether the side of the glass cover plate 20 placed upwards is a tin surface or an air surface.

[0027] Refer to Figure 1 , in this embodiment, the detection device is a surface stress tester 40, and the surface stress tester 40 is non-contact. The detection port of the surface stress tester 40 faces the upper surface of the transportation assembly line 10 to detect the upper surface of the glass cover plate 20 transported below the surface stress tester 40, so as to ensure that the glass cover plates 20 transported to the ink screen printing station are all placed with the air surface side upwards. The surface stress tester 40 can distinguish the tin surface and the air surface of the glass by testing the tempering depth and surface stress of the glass cover plate 20. The side that can normally detect the tempering depth and surface stress is the air surface.

[0028] Furthermore, refer to Figure 1, an optical sensor 50 is provided on the side of the surface stress tester 40. The optical sensor 50 is used to sense whether the glass cover plate 20 reaches below the surface stress tester 40, so that the surface stress tester 40 can detect the surface of the glass cover plate 20. In this embodiment, a controller 60 is provided on the transportation assembly line 10. The controller 60 is electrically connected to the optical sensor 50 and the surface stress tester 40 to control the surface stress tester 40 to perform detection when the optical sensor 50 senses that the glass cover plate 20 reaches below the surface stress tester 40.

[0029] Further, referring to Figure 1 and Figure 2 , the transportation assembly line 10 includes a first-stage assembly line 11, a second-stage assembly line 12, and a lifting assembly line 13 provided between the first-stage assembly line 11 and the second-stage assembly line 12. Both ends of the lifting assembly line 13 are connected to the first-stage assembly line 11 and the second-stage assembly line 12 respectively. The lifting assembly line 13 is used to separate the glass cover plate 20 with the tin side facing up from the transportation assembly line 10. In this embodiment, the conveyor belts 30 on the first-stage assembly line 11, the lifting assembly line 13, and the second-stage assembly line 12 are all independent. The conveyor belts 30 on the first-stage assembly line 11, the lifting assembly line 13, and the second-stage assembly line 12 are all transmitted by belts, and the first-stage assembly line 11, the lifting assembly line 13, and the second-stage assembly line 12 can be normally transmitted when they are connected to each other in pairs.

[0030] Referring to Figure 1 and Figure 2 , the surface stress tester 40 is fixed to the side of the first-stage assembly line 11. When the surface stress tester 40 detects the glass cover plate 20 with the tin side facing up, the glass cover plate 20 is transported to the lifting assembly line 13 for separation, while the glass cover plate 20 with the air side facing up is transported to the ink screen printing station through the lifting assembly line 13 and the second-stage assembly line 12.

[0031] Referring to Figure 1 and Figure 2 , a flipping assembly for flipping the glass cover plate 20 is provided below the second-stage assembly line 12. The flipping assembly is used to flip the glass cover plate 20 up and down so that the air side of the glass cover plate 20 faces up. The flipping assembly includes a flipping table 70 and a receiving assembly line 80. One end of the lifting assembly line 13 facing the second-stage assembly line 12 can be lowered to connect with one end of the flipping table 70 to transport the glass cover plate 20 to the flipping table 70 and flip it onto the receiving assembly line 80.

[0032] Referring to Figure 1 and Figure 2, a lifting cylinder 90 for controlling lifting is provided below the lifting assembly line 13, and a fixing platform 100 for fixing the lifting cylinder 90 is provided below the lifting assembly line 13. One end of the lifting cylinder 90 is fixed on the fixing platform 100, and the piston rod of the lifting cylinder 90 is connected upward to the lifting assembly line 13. The lifting cylinder 90 is used to control the lifting assembly line 13 to descend and connect with the turning platform 70, so as to move the glass cover plate 20 with the tin surface facing up to the turning platform 70 for turning. In this embodiment, the lifting cylinder 90 is electrically connected to the controller 60 to control the lifting assembly line 13 to descend when the surface stress tester 40 detects the glass cover plate 20 with the tin surface facing up and moves onto the lifting assembly line 13.

[0033] Refer to Figure 2 , a turning plate 71 is provided on the turning platform 70, and a suction cup 711 for adsorbing the glass cover plate 20 is provided on the turning plate 71. An air extraction pump 712 is provided inside the turning platform 70. The suction cup 711 is connected to the air extraction pump 712 to adsorb the glass cover plate 20, facilitating subsequent turning operations.

[0034] Refer to Figure 2 , a turning shaft 72 is rotatably provided inside the turning platform 70. The turning shaft 72 is connected to one side of the turning plate 71. One side of the turning shaft 72 is the receiving assembly line 80. Both ends of the turning shaft 72 are rotatably provided on two opposite inner walls of the turning platform 70. The turning shaft 72 can drive the turning plate 71 to rotate around the axis of the turning shaft 72, so that the glass cover plate 20 on the turning plate 71 can be turned onto the receiving assembly line 80. In this embodiment, the upper surface of the receiving assembly line 80 and the lower surface of the turning plate 71 are on the same horizontal plane.

[0035] Further, refer to Figure 1 , one end of the turning shaft 72 is connected to a motor 73. After the suction cup 711 adsorbs the glass cover plate 20, the motor 73 controls the turning shaft 72 to rotate towards the direction close to the receiving assembly line 80 to complete the turning operation.

[0036] Refer to Figure 2 and Figure 3 , the receiving assembly line 80 is located below the second-stage assembly line 12, and the receiving assembly line 80 is perpendicularly arranged with the second-stage assembly line 12. A telescopic manipulator 110 is fixed at one end of the receiving assembly line 80 away from the turning platform 70. The telescopic manipulator 110 can telescopically move towards or away from the surface of the second-stage assembly line 12. In this embodiment, the driving structure for controlling the telescopic movement of the telescopic manipulator 110 is a cylinder. Controlling the telescopic movement with a cylinder is a prior art and will not be elaborated here.

[0037] Refer to Figure 2 and Figure 3, a suction head 111 is provided at the end of the telescopic manipulator 110. The suction head 111 can move up and down. A telescopic rod for controlling the lifting of the suction head 111 is provided on the telescopic manipulator 110. The suction head 111 can suck downward to reach the glass cover plate 20 on one side of the telescopic manipulator 110, and transport the glass cover plate 20 to the second-stage production line 12 through the telescopic movement of the telescopic manipulator 110, so that the flipped glass cover plate 20 returns to the second-stage production line 12 and is transported to the ink screen printing station.

[0038] The device for distinguishing the tin surface and the air surface of the soda-based tempered glass cover plate 20 detects the surface of the glass cover plate 20 by setting a surface stress tester 40. The glass cover plate 20 with the air surface facing up can be directly transported to the ink screen printing station along the transport production line 10 for screen printing, while the glass cover plate 20 with the tin surface facing up reaches the flipping table 70 through the lifting production line 13, is flipped and then transported onto the receiving production line 80, and is adsorbed back to the second-stage production line 12 by the telescopic manipulator 110 for continuous transportation, so as to complete the operation of distinguishing the tin surface and the air surface of the glass cover plate 20 and flipping the glass cover plate 20 with the tin surface facing up, ensuring that the glass cover plates 20 reaching the ink screen printing station for screen printing all have the air surface facing up.
