Referring to fig. 2 and 4, an intelligent drying and transferring method implemented by the intelligent drying and transferring device includes the following steps:

s1, a feeding process, wherein the process is used for transporting the LCD screen of the blue gel to be solidified to the bottom of the transferring and drying chamber 11 from the feeding position 12.

S1-1, the feeding mechanical arm grabs the LCD screen of the blue gel to be solidified in the feeding position 12, and the LCD screen is placed on the transfer tray 2 located at the uppermost end of the downward transfer tray set from the feeding position 12, the LCD screen is placed on the anti-skid mat net in a tiled mode, and the anti-skid mat net increases the friction force between the LCD screen and the transfer tray 2 so that the placement of the LCD screen is more stable.

S1-2, after the LCD screen is fully filled in the transfer tray 2, the first transfer mechanism 33 and the lower transfer bracket 32 cooperate to drive the transfer tray 2 at the lowest end of the lower transfer tray group to be separated from the lower transfer bracket 32, so that the transfer tray 2 at the lowest end of the lower transfer tray group can move downwards under the action of gravity. Specifically, the method comprises the following steps:

the horizontal moving driving member 332 drives the first moving platform 331 to move to the lower side of the lower transporting bracket 32 along the transverse direction of the machine case 1 through the horizontal moving piston rod, and then the first lifting driving member 333 drives the first moving platform 331 to ascend through the first lifting piston rod so that the first moving platform 331 abuts against the lower end disk surface of the disk body 21 of the transporting tray 2 located at the lowest end of the lower transporting tray set.

The second driving member 322 drives the lower tray body 321 to slide in a direction away from the lower tray set, so that the lower tray body 321 is separated from the lower tray set, and the lower tray set loses the load of the lower tray body 321 and is placed on the first transfer platform 331 under the action of gravity. The first lifting driving member 333 drives the first moving platform 331 to move downwards for a certain distance, and the upper tray group moves downwards along with the first moving platform 331 under the action of gravity. The distance is not more than the distance between the surfaces of two adjacent transfer trays 2 in the downward transfer tray group. At this time, the second driving member 322 drives the lower tray body 321 to move toward the direction close to the lower tray group, so that the lower tray body 321 contacts with the lower end surface of the transfer tray 2 at the next lower end of the lower tray group, and at this time, the lower tray body 321 can support the lower tray group again to stabilize the placement of the lower tray group.

The first lifting/lowering driving member 333 drives the first transfer platform 331 to continue moving downward, the transfer tray 2 at the next lower end of the lower transfer tray group is supported on the lower bracket body 321 and does not continue moving downward, and the transfer tray 2 at the lowermost end of the lower transfer tray group continues moving downward along with the first transfer platform 331, so that the first transfer platform 331 can drive the transfer tray 2 at the lowermost end of the lower transfer tray group to be separated from the transfer tray 2 at the next lower end.

S1-3, the second flatting mechanism 34 transports and stacks the transfer tray 2 at the uppermost end of the upper tray group on the lower tray group so that the transfer tray 2 becomes the uppermost transfer tray 2 of the new lower tray group. Specifically, the method comprises the following steps:

the longitudinal translation driving member 343 drives the second translation table 341 to slide along the longitudinal direction of the housing 1 through the longitudinal translation piston rod, so that the second translation table 341 extends between the uppermost transfer tray 2 of the upper transfer tray set and the next upper transfer tray 2 (the second from top to bottom), and the rod part 221 of the positioning member 22 of the uppermost transfer tray 2 of the upper transfer tray set is embedded in the translation positioning groove of the second translation table 341 to position the connection position between the transfer tray 2 and the second translation table 341. Then, the second lifting driving member 342 drives the second transfer table 341 to ascend through the second lifting piston rod, so that the second transfer table 341 first collides with the uppermost transfer tray 2 of the upper transfer tray set, the second lifting driving member 342 then drives the second transfer table 341 to continuously ascend, the uppermost transfer tray 2 of the upper transfer tray set is continuously moved upward by the pushing of the second transfer table 341, and the rest transfer trays 2 in the upper transfer tray set stay on the upper tray body 311 under the action of gravity, so that the uppermost transfer tray 2 of the upper transfer tray set and the next uppermost transfer tray 2 are separated. At this time, the transverse translation driver 344 drives the second transfer table 341 to move along the transverse direction of the casing 1 by transversely translating the piston rod, so that the transfer tray 2 on the second transfer table 341 moves to the upper side of the lower transfer tray group. The second elevating driving member 342 then drives the second transfer table 341 to descend, so that the transfer tray 2 on the second transfer table 341 is stacked on the transfer tray 2 of the lower transfer tray group, and thus the transfer tray 2 becomes a new uppermost transfer tray 2 in the lower transfer tray group.

S1-4, repeating the steps S1-1 to S1-3 to make the transfer tray 2 in the downward tray group continuously move downward.

And S2, a discharging process, wherein the process is used for transporting the LCD screen from the lower end of the transferring drying chamber 11 to a discharging position 13.

S2-1, the discharging mechanical arm grabs the LCD screen on the transfer tray 2 positioned at the uppermost end of the upper transfer tray group and places the LCD screen into the discharging position 13, and therefore the working step of taking out the blue gel solidified LCD screen from the transfer tray 2 positioned at the uppermost end of the upper transfer tray group is completed.

S2-2, S2-2 and S1-3 are completed by the same set of second flat motion mechanism 34, step S1-3 is completed and step S2-2 is completed, and the second flat motion mechanism 34 circularly performs step S2-2 and step S1-3. After the second traverse mechanism 34 transports and stacks the uppermost transfer tray 2 of the upper tray group on the lower tray group, the next uppermost transfer tray 2 of the upper tray group becomes a new uppermost transfer tray 2 of the upper tray group.

S2-3, the step S2-3 and the step S1-2 are completed by the same set of the first flatting mechanism 33, the step S2-2 is immediately performed after the first flatting mechanism 33 completes the step S1-3, and the step S2-3 and the step S1-2 are circularly performed by the first flatting mechanism 33. The first flatting mechanism 33 cooperates with the upper transporting bracket 31 to drive the transporting tray 2 transported by the lower transporting bracket 32 to jack up the upper transporting tray group, and make the transporting tray 2 transported by the lower transporting bracket 32 become a new transporting tray 2 at the lowest end of the upper transporting tray group, specifically:

the horizontal movement driver 332 drives the first transfer table 331 to slide reversely along the lateral direction of the housing 1 by horizontally moving the piston rod, so that the first transfer table 331 moves the transfer tray 2 taken out from the lowermost side of the lower transfer tray group to the lower side of the upper transfer tray group. The first lifting driving member 333 drives the first moving platform 331 to move upward to drive the transfer tray 2 to move upward until the transfer tray 2 on the first moving platform 331 is abutted against the transfer tray 2 at the lowest end in the upper transfer tray set. At this time, the first driving member 312 drives the upper tray body 311 to move in a direction away from the upper tray group in the longitudinal direction of the casing 1 until the upper tray body 311 slides out of the upper tray group, which loses the bearing force of the upper tray body 311 to be stacked on the transfer tray 2 on the first transfer table 331 by the gravity. The first lifting/lowering driving member 333 drives the first transfer table 331 to move upwards continuously so that the first transfer table 331 can jack up the upper transfer tray group through the transfer tray 2 on the first transfer table 331. At this time, the transfer tray 2 transferred by the lower tray 32 becomes the transfer tray 2 at the lowermost end of the new upper tray group.

The first driving member 312 drives the upper tray body 311 to slide in the longitudinal direction of the housing 1 in the opposite direction, so that the upper tray body 311 abuts against the lower end surface of the transfer tray 2 on the first transfer table 331 to support the transfer tray 2 on the first transfer table 331. At this time, the upper tray set can be stably placed on the upper tray body 311.

Then, the first moving platform 331 is driven by the first lifting driver 333 to move downwards, the transfer tray 2 receives the bearing force of the upper bracket body 311 and does not move downwards any more, so that the first moving platform 331 is separated from the transfer tray 2, and the horizontal moving driver 332 drives the first moving platform 331 to move back to the lower side of the lower carrier 32 along the transverse direction of the casing 1.

S2-4, repeating the steps S2-1 to S2-3 to make the transfer tray 2 in the upper tray group move upward continuously.
