Specifically, there are adjacent first and second conveyance mechanisms 10 and 20 in the conveyance direction on the production line of the glass cover plate 90. The first conveying mechanism 10 and the second conveying mechanism 20 are respectively provided with a first conveying belt 11 and a second conveying belt 21 which can run along the conveying direction, wherein the first conveying mechanism 10 is fixedly provided with a material blocking piece 15 at one end of the first conveying belt 11, which is close to the second conveying belt 21, and meanwhile, the material blocking piece 15 is in clearance fit with the first conveying belt 11, so that the glass cover plate 90 on the first conveying belt 11 can be blocked at the end part, the glass cover plate 90 to be dried is positioned, and the normal running of the first conveying belt 11 is not affected.
In addition, the glass cover plate drying device is provided with a drying box 30 and a drying transmission mechanism 40, wherein the drying box 30 is positioned between the first conveying mechanism 10 and the second conveying mechanism 20, and is provided with a feeding opening 301 and a discharging opening 302 which are respectively opposite to the first conveying belt 11 and the second conveying belt 21, and are respectively used for taking the glass cover plate 90 to be dried from the first conveying belt 11 through the feeding opening 301, and discharging the dried glass cover plate 90 to the second conveying belt 21 through the discharging opening 302, so that normal circulation of subsequent stations is performed. The wall of the drying box 30 is provided with a drying structure for providing drying energy to the inner space of the drying box 30 to dry the glass cover plate 90.
The drying transmission mechanism 40 is disposed in the drying box 30 in a manner that enables the glass cover plate 90 to be conveyed from the first conveyor belt 11 to the second conveyor belt 21 in a predetermined pattern including repeatedly turning the glass cover plate 90 between the front and the back and causing the glass cover plate 90 to stay in the drying box 30 for a predetermined length of time. In this way, the front side and the back side of the glass cover plate 90 are turned over and exchanged in the drying box 30 at a certain frequency, so that the glass cover plate 90 can be uniformly dried, larger water drops on the surface of the glass cover plate 90 can automatically slide under the action of gravity in the turning process, the drying time is reduced, and the residence time of the glass cover plate 90 in the drying box 30 is controlled, so that the glass cover plate 90 can be effectively and sufficiently dried, and the drying transmission mechanism 40 can realize high-speed transportation of the glass cover plate 90 between the first conveying belt 11 and the second conveying belt 21, and further ensure the drying quality of the glass cover plate 90.
As a preferred embodiment, the drying and driving mechanism 40 has at least two, and at the same time, the drying and driving mechanism 40 includes a rotatable hollow rotating shaft 41 and at least three groups of vacuum chucks 42 uniformly distributed on the surface of the hollow rotating shaft 41 along the circumferential direction, wherein each group of vacuum chucks 42 is configured to be suitable for adsorbing one glass cover plate 90, and the suction nozzles of the vacuum chucks 42 are flexible suction nozzles and have high temperature resistant property, so that damage to the adsorbed glass cover plate 90 can be reduced in the drying box 30, and at the same time, the glass cover plate 90 can be ensured not to be separated from the vacuum chucks 42 by a little deformation when the glass cover plate 90 is delivered between two adjacent drying and driving mechanisms 40 during the rotation of the hollow rotating shaft 41. The flexibility of the suction nozzle on the vacuum chuck 42 is mainly based on the choice of its material, ensuring that it still has a certain suction force when local deformations occur. In general, the suction nozzle of the vacuum chuck 42 employs a small-caliber suction nozzle head to reduce the friction area between the vacuum chuck 42 and the glass cover plate 90 when the hollow shaft 41 rotates. Each set of vacuum cups 42 includes two circumferentially spaced rows of cups, each row including three to five axially spaced or evenly spaced cups, ensuring stable suction of each glass cover plate 90.
In addition, the hollow rotating shaft 41 is formed with air supply channels 401 which are respectively communicated with each group of the vacuum sucking discs 42 along the axial direction of the shaft cavity, meanwhile, one end of the hollow rotating shaft 41 is also provided with a gas control valve 43, and the other end is sealed, wherein the gas control valve 43 is fixedly arranged on the drying box 30, and a valve port 403 is arranged corresponding to each air supply channel 401, a valve 431 is arranged in the valve port 403 at a preset position of the gas control valve 43, the valve 431 on the drying transmission mechanism 40 close to the second conveying belt 21 is defined as a second valve, and the valves 431 on the rest drying transmission mechanisms 40 are defined as a first valve;
all the drying driving mechanisms 40 are linked with each other, so that when the group of vacuum chucks 42 on the drying driving mechanism 40 close to the first conveying belt 11 adsorb the glass cover plate 90 and rotate to the group of vacuum chucks 42 on the next drying driving mechanism 40, the adsorption force is gradually weakened under the influence of the valve 431, so that the next drying driving mechanism 40 can adsorb and receive the glass cover plate 90 from the vacuum chucks 42 on the previous drying driving mechanism 40 based on the larger adsorption force, and the difference of the adsorption force is realized based on the difference of the sealing degree of the valve 431 to the valve port 403. By the action of the valve 431, the air supply amount is reduced in the air supply channel 401 corresponding to the valve 431, and because the air supply channel 401 and the vacuum chuck 42 rotate synchronously along with the hollow rotating shaft 41, when the air supply channel 401 approaches to or even faces the valve 431, the gradual reduction of the air supply amount in the air supply channel 401 can reduce the adsorption force of the corresponding vacuum chuck 42, and the vacuum chuck 42 on the drying transmission mechanism 40 for receiving the glass cover plate 90 still maintains the normal suction force, when two vacuum chucks 42 adsorb on the glass cover plate 90 at the same time, the glass cover plate 90 on the previous drying transmission mechanism 40 is sucked by the vacuum chuck 42 on the next adjacent drying transmission mechanism 40, so that the transfer of the glass cover plate 90 among a plurality of drying transmission mechanisms 40 is completed. Because the vacuum chucks 42 on two adjacent drying driving mechanisms 40 are adsorbed on the opposite front and back surfaces of the glass cover plate 90, and the glass cover plate 90 also continuously rotates on the same drying driving mechanism 40, the glass cover plate 90 can be uniformly dried in the drying box 30. In addition, the second valve 4 seals the corresponding valve port 403 completely and faces the second conveyor belt 21, when the drying transmission mechanism 40 close to the second conveyor belt 21 rotates the suction glass cover plate 90 to a position close to the second conveyor belt 21, the air supply channel 401 corresponding to the vacuum chuck 42 of the suction glass cover plate 90 is sealed completely by the second valve, the suction force is lost completely, and the glass cover plate 90 falls onto the second conveyor belt 21 under the action of gravity and is conveyed away by the second conveyor belt 21 for subsequent station processing.
Further preferably, in the direction of the vertical tangential plane of the valve port 403, the first valve occupies 50% -95% of the area of the corresponding valve port 403, such as 60%, 75%, 90%, etc., and the sealing volume of the first valve may be reasonably set based on factors such as the size of the adsorption force and the weight of the glass cover plate 90, so that the air supply channel 401 corresponding to the first valve provides the air supply amount of a predetermined size for the rotated vacuum chuck 42, thereby ensuring that the vacuum chuck 42 can adsorb the glass cover plate 90 through a lower adsorption force, and facilitating the transfer to the vacuum chuck 42 on the next drying transmission mechanism 40.
As a preferred embodiment, referring to fig. 6 and 9, the number of the drying driving mechanisms 40 is two, and at the same time, the two drying driving mechanisms 40 are arranged in parallel in the same height direction and are respectively close to the first conveying mechanism 10 and the second conveying mechanism 20;
furthermore, the vacuum chucks 42 are implemented as four sets. The four groups of vacuum chucks 42 are disposed on the surface of the hollow rotating shaft 41 and are distributed in a cross shape with the hollow rotating shaft 41 as a center, wherein the first valve is located in the valve port 403 on one side of the air control valve 43 facing the second conveying mechanism 20 in the horizontal direction, i.e. the first valve is located in the valve port 403 on the leftmost side of the air control valve 43.
Specifically, for convenience of description, the drying driving mechanism 40 near the right side and the vacuum chuck 42 on the drying driving mechanism 40 are defined as a right driving mechanism 4-1 and a right chuck 4-2, respectively, and the drying driving mechanism 40 near the left side and the vacuum chuck 42 on the drying driving mechanism 40 are defined as a left driving mechanism 4-3 and a left chuck 4-4, respectively. When the device works, the right transmission mechanism 4-1 continuously rotates through the hollow rotating shaft 41 to drive the right sucker 4-2 to synchronously rotate, when the device faces the first conveying belt 11, the glass cover plate 90 on the first conveying belt 11 is adsorbed, the glass cover plate 90 with the adsorption is rotated again, when the device rotates to the leftmost side, the suction force of the right sucker 4-2 for adsorbing the glass cover plate 90 is reduced under the action of the first valve, and at the moment, the left sucker 4-4 is still kept at the adsorption force of a normal size. When the left sucker 4-4 and the right sucker 4-2 are simultaneously adsorbed on the front and back sides of the glass cover plate 90, the left sucker 4-4 with larger adsorption force adsorbs the glass cover plate 90, and meanwhile, the glass cover plate 90 is separated from the right sucker 4-2, so that the glass cover plate 90 is transferred to the left transmission mechanism 4-3 and is driven to synchronously rotate along with the hollow rotating shaft 41 on the left transmission mechanism 4-3. When the left transmission mechanism 4-3 drives the glass cover plate 90 to rotate to the bottom through the hollow rotating shaft, namely, right faces the second conveying belt 21, the adsorption force of the left sucker 4-4 adsorbing the glass cover plate 90 completely disappears under the action of the second valve, and the glass cover plate 90 naturally drops onto the second conveying belt 21 under the action of self gravity, so that the glass cover plate is conveyed away by the second conveying belt 21 and is subjected to subsequent station treatment.
As another preferred embodiment, referring again to fig. 1 to 4, the drying driving mechanisms 40 are implemented as odd numbers, such as three, five or seven, and the plurality of drying driving mechanisms 40 are uniformly distributed at two height positions in a fold line, wherein the number of the drying driving mechanisms 40 near the low position is greater than the number of the drying driving mechanisms 40 near the high position;
meanwhile, the vacuum chucks 42 are implemented as six groups, and the six groups of vacuum chucks 42 are respectively distributed at intervals of 60 ° on the surface of the hollow rotating shaft 41, that is, uniformly distributed.
It should be noted that, on the production line of the glass cover plate 90, the residence time of the glass cover plate 90 in the drying box 30 is related to factors such as the rotation speed of the hollow rotating shafts 41, the number of the drying transmission mechanisms 40, the number of groups of the vacuum chucks 42 arranged on the surface of each hollow rotating shaft 41, and the like, so that the technical scheme of simultaneously drying the glass cover plate 90 in the process of processing the glass cover plate 90 is equivalent and is within the scope of protection of the application.
In addition, the technical proposal provided by the application can be used for producing and drying articles based on the same material or related and similar materials. The glass cover plate 90 is also referred to as a glass substrate in some cases, or in the same or different technical fields.

Considering that the suction angle and suction position of the vacuum chuck 42 on the surface are continuously changed during the rotation process of the hollow rotating shaft, although the suction nozzle of the vacuum chuck 42 is a flexible suction nozzle, a certain deformation can be generated, in order to firmly and firmly suck the glass cover plate 90 on the first conveyor belt 11 and firmly and safely receive the dried glass cover plate 90 during the transportation process, the damage rate of the glass cover plate 90 is reduced, and preferably, the first conveyor mechanism 10 and the second conveyor mechanism 20 are further provided with a first mounting frame 12, a first supporting member 13, a second mounting frame 22 and a second supporting member 23;

Typically, the vacuum chuck 42 to which the glass cover plate 90 is to be sucked is maintained at a position closest to the first conveyor belt 11 for a period of 2 to 5 seconds, so that the first conveyor belt 11 can hold up the glass cover plate 90 and firmly suck the glass cover plate onto the vacuum chuck 42. Similarly, the second conveyor 21 will rise to a predetermined height when the oven-dried glass cover plate 90 is transported to the lowest end by the oven-drying transmission mechanism 40 near the second conveyor 21, so as to avoid the disturbance of the rotation of the glass cover plate 90 due to the advance rising movement.
