[0002] Glass substrates used in the semiconductor industry are stacked in a material box during transportation. One side of the material box is open to facilitate the transportation of the glass substrates from the material box. However, since the surface of the glass substrates is smooth, they may fall out of the open opening during the movement of the material box, causing damage to the glass substrates. In addition, since the surface of the glass substrates is smooth, they may slip when being removed from the material box, affecting the transportation of the glass substrates.

The blocking mechanism limits the glass substrate in the placement groove 31 from falling out of the discharge port, and the blocking mechanism contacts the top surface of the glass substrate when the glass substrate is transported (moved out) from the box body 3; the glass substrate is blocked during the movement of the material box to prevent the glass substrate from falling out of the material box, and the glass substrate is contacted with the top surface of the glass substrate during the process of peeling the substrate out of the material box, thereby increasing the friction between it and the roller 21, and preventing slipping during the process of moving the material box.

[0075] like Figure 3 and Figure 4 and Figure 5 As shown, in an optional embodiment, the blocking mechanism includes: a rotating block 4; a recess 41 is provided on one side of the rotating block 4 facing the inner side wall of the placement groove 31; the recess 41 can be circular; a limiting component is provided in the recess 41, and the limiting component is slidably connected with the recess 41; the limiting component is adapted to the air hole 32 provided on the inner side wall of the placement groove 31, and the protruding recess 41 of the limiting component extends into the corresponding air hole 32; the air hole 32 can be circular; the cooperation between the limiting component and the recess 41 can make the rotating block 4 unable to rotate, so as to block the glass substrate through the rotating block 4 to prevent the glass substrate from falling from the open opening of the placement groove 31; if only the plate body blocking method is used to block the discharge port, then when the glass substrate is moved out of the box body 3, the plate body cannot press the glass substrate, the friction between the glass substrate and the roller 21 cannot be increased, and the glass substrate cannot be prevented from slipping during the removal process.

[0076] like Figure 5As shown, in an optional embodiment, the limit assembly includes: two arc-shaped members 42; the arc-shaped member 42 is connected to the inner wall of the recess 41 through a spring 47; part of the arc-shaped member 42 is arranged in the recess 41, and part of it protrudes from the recess 41; there is a gap between the two arc-shaped members 42, and the two arc-shaped members 42 and the gap therebetween form a circular ring, which is adapted to the air hole 32; a baffle 43 is arranged on the inner wall of the arc-shaped member 42, and there is also a gap between the baffles 43 of the two arc-shaped members 42; the baffle 43 is arched in the direction away from the glass substrate; when the arc-shaped member 42 extends into the air hole 32, the distance between the bottom surface of the rotating block 4 and the inner bottom surface of the placement groove 31 is less than the thickness of the glass substrate; the arc-shaped member 42 can be made of elastic material, such as rubber; the two arc-shaped members 42 without deformation and the gap therebetween can form a circular ring adapted to the air hole 32, and the two arc-shaped members 42 can be inserted into the air hole 32. The rotating block 4 is limited to prevent the rotating block 4 from rotating. At this time, the rotating block 4 can play a blocking role on the glass substrate to prevent the glass substrate from falling out of the opening of the placement groove 31; the gap between the arc-shaped parts 42 can facilitate the arc-shaped parts 42 to gather toward the axis direction of the ring, so that the size of the ring is smaller than the size of the air hole 32, which is more convenient for the arc-shaped part 42 to be inserted into the air hole 32; the gap width between the baffles 43 can facilitate the two baffles 43 to approach each other, and avoid the baffles 43 from hindering the deformation of the arc-shaped part 42; when the gas blows the baffle 43, the gap between the two baffles 43 will be reduced, and the baffle 43 will drive the two arc-shaped parts 42 to approach (gather toward the axis direction of the ring), so that the size of the ring is smaller than the size of the air hole 32, which is more convenient for the arc-shaped part 42 to be inserted into the air hole 32, that is, the gas blows the baffle 43 to reduce the gap between the two arc-shaped parts 42 away from the recess 41, and the direction of the gap gathering and reducing is shown in f in the figure.

[0077] In an optional embodiment, a rotating shaft 44 is provided on the rotating block 4, and the rotating shaft 44 is located above the recess 41; the rotating shaft 44 is rotatably connected to the inner wall of the placement groove 31; when the arc-shaped member 42 extends into the air hole 32, the rotating block 4 cannot rotate; the rotating block 4 can be rotated by the rotating shaft 44, and when the arc-shaped member 42 is located in the air hole 32, it hinders the rotation of the rotating block 4, thereby preventing the rotating block 4 from rotating.

[0078] In an optional embodiment, a groove body 45 is provided on the rotating block 4, and the groove body 45 is located above the recess 41; the inner wall of the groove body 45 is connected to the inner wall of the recess 41 through a flow channel 46; when the arc-shaped member 42 is retracted into the recess 41, the position where the flow channel 46 is connected to the inner wall of the recess 41 is farther away from the air hole 32 than the end face of the arc-shaped member 42; when the arc-shaped member 42 is completely retracted into the recess 41, the position where the gas enters the recess 41 is between the arc-shaped member 42 and a closed side of the recess 41, and at this time, the gas can push the arc-shaped member 42 out of the recess 41.

[0079] In an optional embodiment, two air passages are vertically opened inside the box body 3, and the bottom ends of the air passages are located on the bottom surface of the box body 3; the air passages are connected to the corresponding rows of air holes 32; an air pipe corresponding to the air passage is arranged below the box body 3, the bottom of the air pipe is connected to the air source, the top of the air pipe is closed, and an air outlet hole is opened on the side wall of the air pipe; the air pipe is suitable for being inserted into the air passage to ventilate to the aligned air holes 32 through the air outlet hole, and the gas blows the arc-shaped member 42 to make the arc-shaped member 42 detach from the air hole 32 and shrink into the recess 41, at this time, when the glass substrate moves, it drives the rotating block 4 to rotate, and the rotating block 4 contacts the top surface of the glass substrate; the gas can make the arc-shaped member 42 detach from the air hole 32, and the rotating block 4 resumes rotation.

[0080] like Figure 6 As shown, in an optional embodiment, the discharging device 2 includes: a plurality of rollers 21, and a driver 22 corresponding to the rollers 21; the rollers 21 are connected to the driver 22; a first lifting hole 33 corresponding to the rollers 21 is opened on the bottom surface of the box body 3, and the roller 21 contacts the bottom surface of the bottom glass substrate after passing through the first lifting hole 33; the driver 22 can be a motor, etc., and the rotation of the rollers 21 can drive the bottom glass substrate to move; all rollers 21 can be synchronously driven by the same motor.

[0081] like Figure 7 and Figure 8 As shown, in an optional embodiment, the lifting device 1 includes: a vertical lifting mechanism 11 and a support plate 12; the support plate 12 is connected to the vertical lifting mechanism 11; the support plate 12 is suitable for supporting the box body 3; a second lifting hole 13 corresponding to the first lifting hole 33 is opened on the support plate 12; the roller 21 passes through the second lifting hole 13 and the first lifting hole 33 and contacts the bottom surface of the bottommost glass substrate; the vertical lifting mechanism 11 is suitable for driving the support plate 12 to move up and down, so as to drive the box body 3 to move up and down; when the bottommost glass substrate is moved out, the vertical lifting mechanism 11 drives the support plate 12 to descend, so that the roller 21 can contact the second to last glass substrate, so as to realize moving the glass substrate out of the box body 3 layer by layer from bottom to top.

[0082] In an optional embodiment, a transport device is provided at the discharge port of the box body 3, and the transport device is suitable for carrying the glass substrate discharged from the discharge port; a shooting module is provided on one side of the transport device, and the shooting module is electrically connected to a control module; the control module is also electrically connected to the air source and the driver 22; the shooting module is suitable for capturing an image of the transport device, and the control module is configured to determine whether the glass substrate currently discharged from the box body 3 is completely moved to the transport device based on the image; the control module is suitable for controlling the air source to ventilate for the first time, so as to blow the arc-shaped member 42 into the concave portion 41, and when the glass substrate is completely moved to the transport device, the arc-shaped member 42 is blown into the concave portion 41. After the transmission device, the control module controls the air source to stop ventilation for a preset time, and then controls the air source to ventilate for the second time. The air volume of the second ventilation is less than the air volume of the first ventilation, so that the arc-shaped member 42 can be pushed out of the air hole 32 during the first ventilation. During the first ventilation, the thrust of the gas on the baffle 43 is greater than the elastic force of the spring 47, so that the arc-shaped member 42 can be pushed out of the air hole 32 and enter the recess 41. During the second ventilation, the thrust of the gas on the baffle 43 is less than the elastic force of the spring 47. At this time, the gas pushes the two baffles 43 to move closer, so that the arc-shaped member 42 moves closer. The circular ring formed by the arc-shaped member 42 is smaller than the air hole 32, which facilitates the arc-shaped member 42 to re-extend into the air hole 32.

[0083] like Fig. 9 and Fig.10 As shown, in the initial state, the rotating block 4 is in a vertical state, the arc-shaped member 42 is inserted into the air hole 32, the air hole 32 is completely blocked by the rotating block 4, the glass substrate is placed in the placement groove 31, and the rotating block 4 cannot rotate. The rotating block 4 blocks the glass substrate to prevent the glass substrate from falling out of the open opening of the placement groove 31. When the box body 3 moves onto the support plate 12, the vertical lifting mechanism 11 can drive the support plate 12 to descend, so that the roller 21 contacts the bottom surface of the glass substrate of the lowest layer, and the air pipe is inserted into the airway at this time, and the air outlet on the air pipe is aligned with the air hole 32 corresponding to the lowest placement groove 31. The control module controls the air source to ventilate for the first time, and the gas enters the air hole 32 through the air pipe to blow the baffle 43, so that the arc-shaped member 42 enters the recessed portion 41, and the arc-shaped member 42 no longer hinders the rotation of the rotating block 4. The roller 21 rotates to transport the glass substrate out of the box body 3. The glass substrate drives the rotating block 4 to rotate during the movement, and the rotation direction is as shown in FIG. Fig. 9As shown in F, the rotating block 4 gradually rotates to contact with the top surface of the glass substrate. At this time, the rotating block 4 has a certain pressing effect on the glass substrate, which increases the friction between the glass substrate and the roller 21 to prevent the glass substrate from slipping during removal. At this time, the groove body 45 is aligned with the air hole 32 as the rotating block 4 rotates. The gas blown out of the air hole 32 enters the recess 41 through the groove body 45, and pushes the arc-shaped member 42 out of the recess 41. At this time, the relative position of the recess 41 is the position where the air hole 32 is not opened in the inner wall of the placement groove 31. The arc-shaped member 42 is pushed to be in close contact with the inner wall of the placement groove 31 to maintain the pressing effect of the rotating block 4 on the glass substrate. The rotating block 4 rotates to expose part of the air hole 32. The gas blown out from the exposed part of the air hole 32 cleans the surface of the glass substrate to avoid impurities on the surface of the glass substrate. When a glass substrate After completely moving out of the box body 3, the control module controls the air source to stop blowing. At this time, the rotating block 4 rotates back to the vertical state due to factors such as gravity. Since there is no circular ring formed by the gas arc member 42 to adapt to the air hole 32 at this time, the arc member 42 cannot accurately re-extend into the air hole 32. The control module controls the air source to ventilate for the second time, and the gas blows the baffle 43 to make the arc member 42 bend and close to the axis of the circular ring, so that the size of the circular ring is smaller than the air hole 32. The arc member 42 is smoothly extended into the air hole 32 through the reset of the spring 47. After the arc member 42 extends into the air hole 32, the control module stops the air source blowing, and the vertical lifting device 1 drives the support plate 12 to descend, so that the roller 21 contacts the bottom surface of the glass substrate of the second to last layer. At this time, the length of the air pipe inserted into the airway increases, so that the air outlet is aligned with the next air hole 32; the reciprocating cycle makes the substrates in the box body 3 move out of the box body 3 layer by layer.

[0084] At least one other disclosed embodiment further provides a discharging method using the above-mentioned glass substrate discharging system, comprising: as the material box descends, the discharging device 2 extends into the material box from the bottom surface of the material box, and the discharging device 2 transports the glass substrates in the material box out of the material box layer by layer.

[0085] In summary, the glass substrate discharging system comprises: a lifting device 1 and a discharging device 2; the lifting device 1 is arranged on one side of the discharging device 2, and the lifting device 1 is suitable for driving a material box with a plurality of layers of glass substrates to be placed up and down; the material box is located above the discharging device 2, and as the material box descends, the discharging device 2 is suitable for extending into the material box from the bottom surface of the material box, and the discharging device 2 is suitable for transporting the glass substrates in the material box out of the material box layer by layer; wherein the material box comprises: a box body 3; one side of the box body 3 in the conveying direction of the discharging device 2 is open to form a discharging port on the box body 3; and a plurality of layers of glass substrates are placed on the inner wall of the box body 3. The placing grooves 31, two placing grooves 31 on the same layer are used to support a glass substrate; one end of the placing groove 31 is connected to the discharge port; a blocking mechanism is arranged in the placing groove 31, and the blocking mechanism is arranged close to the discharge port. The blocking mechanism limits the glass substrate in the placing groove 31 from falling out of the discharge port, and the blocking mechanism contacts the top surface of the glass substrate when the glass substrate is moved out of the box body 3; the glass substrate is blocked during the movement of the material box to prevent the glass substrate from falling out of the material box, and the top surface of the glass substrate is contacted during the process of peeling the substrate out of the material box, thereby increasing the friction between it and the roller 21 and avoiding slipping during the process of moving the material box.
