[0026] like Figure 1 , Figure 2 and Figure 3 As shown, a liquid crystal panel rotary conveying mechanism includes a conveying component and a reversing component.

[0027] The conveying assembly includes multiple parallel conveying shafts 1, any conveying shaft 1 is connected to the conveying drive device 5, and a liquid crystal panel is mounted on the conveying shaft 1. Driven by the conveying drive device 5, the multiple conveying shafts 1 rotate synchronously around their own axes to convey the liquid crystal panel toward the first direction a.

[0028] The reversing assembly is used to lift and rotate the liquid crystal panel on the conveying assembly to a preset angle, and then put it back on the conveying assembly. It includes a carrying plate 2 and a reversing drive device 3 that drives the carrying plate 2. The carrying plate 2 is set as a square frame structure, and a plurality of carrying blocks 21 are fixed on its upper surface. The upper end surfaces of the plurality of carrying blocks 21 are made of silicone material, and the upper end surfaces of the plurality of carrying blocks 21 are all located in the same plane and abut against the liquid crystal panel during the reversing action.

[0029] In addition, in a preferred embodiment of the present application, an opening may be provided at the top of the carrying block 21, and the opening is configured as a trumpet. An air passage connected to a negative pressure device is provided in the carrying plate 2, and the air passage is connected to the opening, and under the action of a negative pressure device such as an air pump, the carrying block 21 can absorb the material, thereby preventing the liquid crystal panel from sliding relative to the carrying plate 2 during the reversing action.

[0030] like Figure 2 and Figure 5As shown, the mounting plate 2 is provided with positioning devices 4 on both sides of the second direction b perpendicular to the first direction a, which are used to position the position of the liquid crystal panel relative to the second direction b before and after the liquid crystal panel switches direction. The positioning device 4 includes positioning rods 41 arranged in pairs on both sides of the mounting plate 2 along the second direction b in the vertical direction, and any pair of positioning rods 41 is driven by the positioning driver 42 to perform a clamping movement along the second direction b on the plane where the mounting plate 2 is located. When the pair of positioning rods 41 are performing the clamping movement, the position at which the distance between them is the closest is the positioning position on both sides of the liquid crystal panel. Among them, the positioning driver 42 adopts a cylinder.

[0031] like Figure 3 and Figure 4 As shown, the reversing drive device 3 includes a lifting part 31 and a rotating part 32, which are respectively used to perform lifting and rotating actions on the carrying plate 2. Among them, the carrying plate 2 lifts the material under the drive of the lifting part 31 to make it out of contact with the conveying shaft 1. The lifting part 31 includes a lifting base 311. A lifter 312 is arranged through the lifting base 311. In this embodiment, the lifter 312 adopts a lifting cylinder, and the execution end of the lifter 312 is connected to the rotating part 32 and drives the rotating part 32 to perform lifting and lowering movements. A guide mechanism 313 is also arranged on the lifting base 311. The guide mechanism 313 includes a guide sleeve fixed to the rotating part 32 and the lifting base 311 in the vertical direction, and a guide shaft that passes through the rotating part 32 and the lifting base 311 and cooperates with the guide sleeve.

The transmission mechanism 52 includes a transmission rod 521 and a magnetic wheel.

The transmission rod 521 rotates around its own axis under the action of the conveying drive 51, and drives the multiple conveying shafts 1 to rotate through the magnetic wheel. In this embodiment, the conveying drive 51 adopts a motor.

[0035] Specifically, the magnetic wheel includes a first wheel 522 coaxially fixed to the ends of multiple conveying shafts 1, and a second wheel 523 coaxially fixed to the conveying rod corresponding to the multiple first wheels 522. The first wheel 522 corresponds to the second wheel 523 one by one and is arranged orthogonally. The second wheel 523 rotates synchronously with the transmission rod 521, and transmits the driving force to the first wheel 522 through magnetic force, so that the first wheel 522 drives the conveying shaft 1 to rotate, and transports the liquid crystal panel along the first direction a.
