[0067] The specific working process of the utility model is as follows:

[0068] The positioning section machine table 1 mainly accelerates the glass flowing out of the production line to the specified position and performs side positioning, and then conveys the glass to the lower segment machine table 2 for processing.

[0069] When the glass flowing out of the production line reaches the positioning section machine table 1, the feeding photoelectric sensor 803 senses the glass, and the first roller 502 starts to work and conveys the glass forward; when the glass is conveyed forward, the deceleration photoelectric sensor 804 senses the glass, and the conveying speed of the first roller 502 starts to decrease to stop.

[0070] After the first roller 502 stops conveying, the lifting cylinder 703 operates to lift the supporting beam 6 upward, so that the glass is lifted to be separated from the contact surface of the first roller 502; the conveying belt 602 starts to work and conveys the glass to the positioning wheel 3 for positioning; after the in-place sensor 801 senses the glass, the conveying belt 602 stops working, the lifting cylinder 703 starts to work, the supporting beam 6 is lowered, and the glass falls on the first roller 502 again, so that the first roller 502 starts to work again until the glass is completely separated from the positioning section machine table 1.

[0071] The lower segment machine table 2 mainly uses the suction cup 4 of the turnover arm 11 to suck and turn over the glass conveyed from the positioning section machine table 1, so that the glass is changed from a horizontal state to an inclined vertical state with an angle of 5 degrees and is placed in a glass rack for glass stacking.

[0072] After the lower piece segment feeding photoelectric sensor 131 senses the glass, the second roller 123 starts to work to forwardly convey the glass; after the lower piece segment feeding photoelectric sensor 131 senses the glass, the second roller 123 starts to slow down until the glass contacts with the positioning block, the second roller 123 starts to reverse to convey the glass to the middle position of the lower piece segment machine table 2, and the second roller 123 stops.

[0073] The sub-arm 111 is lifted, the vacuum chuck 4 contacts with the glass, the vacuum pump works to draw vacuum, until the vacuum chuck 4 sucks the glass, and the turnover arm 11 starts to work; the upper frame 9 moves to the glass frame, until the sub-arm 111 moves the glass to the glass frame to place the glass, the vacuum pump stops working and blows air into the vacuum chuck 4 through the vacuum air path, the vacuum chuck 4 releases the glass, and the glass is placed on the glass frame.

[0074] The upper frame 9 returns to the original position and waits for the next glass.
