Description

Technical Field

[0001] The invention belongs to the field of display screen substrate transfer equipment, and in particular relates to an auxiliary equipment for rotating a display screen substrate after cleaning. Background Art

[0002] After polishing, the display screen substrates are placed upright in the insertion cage for soaking and cleaning. Then, the insertion cage with the display screen substrates is lifted by the automatic film placement system to separate it from the cleaning liquid and placed on the auxiliary equipment for rotation. Usually, the auxiliary equipment for rotation is only an L-shaped rotating frame, which can be turned 90 degrees from the vertical state to the horizontal state, so that the display screen substrates can reach the horizontal state. The automatic film placement system then transports the display screen substrates in the insertion cage forward one by one for the next process. When the rotating frame is turned over, it will directly and hard hit the support table, which will cause the display screen substrate to be subjected to a large impact force, which can easily cause it to move, vibrate, or even deform greatly, thereby causing wear on adjacent display screen substrates and reducing product quality.

[0029] A plurality of slide rails are fixedly connected to both inner side walls of the carrier 2, each slide rail is connected to a strip-shaped slider 3 matching the slide rail, and a protective pad 4 is fixedly connected to the surface of the slider 3.

In this embodiment, both ends of the rotating rod 11 are connected to the front side plate 102 and the rear side plate 103 through bearings. Under the drive of the motor 9, the driving wheel 12 drives the driven wheel 13 to rotate, and then drives the rotating rod 11 to rotate, and finally realizes the flipping of the carrier 2.
