[0022] The technical solution of this utility model will be more clearly and completely explained below with reference to the accompanying drawings and through the description of the preferred embodiments of this utility model.

[0023] like Figure 1 and Figure 2 As shown, the preferred embodiment of the liquid crystal glass rapid cooling device of this utility model includes a support platform 1, and a cooling platform 2 is provided above the support platform 1. Both the support platform 1 and the cooling platform 2 are box structures. A cooling plate assembly is provided on the cooling platform 2 for rapidly cooling the liquid crystal glass 6. A lifting mechanism for lifting the liquid crystal glass 6 is provided on the cooling platform 2. The lifting mechanism can lift or lower the liquid crystal glass 6 in the vertical direction. A drive mechanism for driving the lifting mechanism to lift and lower is provided inside the support platform 1.

[0024] like Figure 2 and Figure 3 As shown, the cooling plate assembly is disposed inside the chamber housing of the cooling platform 2. The cooling plate assembly includes a first cooling plate 31, a second cooling plate 32, and a third cooling plate 33 arranged sequentially from top to bottom. The four sides of the first cooling plate 31 are respectively provided with a group of limiting blocks 311. The side of the limiting block 311 facing the liquid crystal glass 6 is inclined, so that when the liquid crystal glass 6 is lowered, it can naturally fall into place along the inclined surface.

[0025] like Figure 6 As shown, the first cooling plate 31 has several air ducts 312 inside, which are blown by vacuum air pressure pipes to achieve rapid heat exchange.

[0026] like Figure 7 As shown, the second cooling plate 32 has a spiral cooling channel 321 inside, and the cooling channel 321 is connected to a refrigeration device to achieve rapid cooling.

[0027] like Figure 1 and Figure 3 As shown, a temperature sensor 313 is embedded in the first cooling plate 31. The temperature sensor 313 is set close to the upper surface of the first cooling plate 31, so that the temperature of the liquid crystal glass 6 can be detected more sensitively.

[0028] like Figure 3 and Figure 4 As shown, the drive mechanism includes a lifting motor 51 installed within the support platform 1. The drive shaft of the lifting motor 51 is parallel to the horizontal plane. A drive wheel 52 is mounted on the output shaft of the lifting motor 51. The lifting motor 51 causes the drive wheel 52 to rotate around its axis. An eccentric shaft 53 is mounted on the outer periphery of the side of the drive wheel 52 away from the lifting motor 51. The eccentric shaft 53 is parallel to the axis of the drive wheel 52, and a connecting rod 54 is rotatably connected to the eccentric shaft 53. When the lifting motor 51 operates, the drive wheel 52 rotates, causing the eccentric shaft 53 to perform circular motion.

[0029] like Figure 3 and Figure 4 As shown, the lifting mechanism includes a lifting plate 41 positioned above the lifting motor 51. A support platform 1 contains several vertically oriented guide rods 42. The lifting plate 41 has ball bearing bushings 43 that cooperate with the guide rods 42. The ball bearing bushings 43 are fitted onto the guide rods 42 and can slide along them. The lifting plate 41 has a drive block 44, and the drive block 44 has a rotating shaft 45 parallel to the eccentric shaft 53. One end of a connecting rod 54, away from the eccentric shaft 53, is rotatably connected to the rotating shaft 45. The eccentric shaft 53 drives the drive block 44 via the connecting rod 54, thus raising or lowering the lifting plate 41.

[0030] like Figure 3 and Figure 4 As shown, the lifting mechanism includes a top pin 46 mounted on the lifting plate 41. The top pin 46 is vertically positioned and passes through the cooling plate assembly. When the lifting plate 41 is at its maximum height, the top tip of the top pin 46 protrudes from the cooling plate assembly and is exposed, allowing it to lift the liquid crystal glass 6. After the lifting plate 41 descends, the top tip of the top pin 46 retracts into the cooling plate assembly, lowering the liquid crystal glass 6 so that it adheres tightly to the first cooling plate 31 for rapid cooling. A second bushing 48 is provided at the bottom of the third cooling plate 33, and a first bushing 47 is provided between the first cooling plate 31 and the second cooling plate 32. The top pin 46 passes through the second bushing 48 and the first bushing 47 in sequence.

[0031] Specific implementation process: After the external robotic arm removes the liquid crystal glass 6 from the heating and drying equipment, the top pin 46 rises, protruding outside the first cooling plate 31 to catch the liquid crystal glass 6. Once the robotic arm places the glass on the top pin 46, the top pin 46 begins to descend, and the position of the liquid crystal glass 6 is adjusted by the limit block 311. After the glass falls onto the first cooling plate 31, heat exchange begins, with air blowing through the air duct 312 to rapidly cool it down. When the temperature sensor 313 detects that the temperature of the liquid crystal glass 6 has dropped to the set temperature, the top pin 46 begins to lift the liquid crystal glass 6. After it reaches its position, the robotic arm removes the liquid crystal glass 6 from the device, and the cooling process ends.

[0032] The above-described specific embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Various modifications, substitutions, and improvements made by those skilled in the art to the technical solutions of the present invention based on the provided description and drawings, without departing from the design concept and spirit of the present invention, should all fall within the scope of protection of the present invention. The scope of protection of the present invention is determined by the claims.
