Therefore, in the process of flat grinding of the glass, the grinding disc 325 and the glass rotate relative to the rack 30 to complete flat grinding operation in a matching manner, which is beneficial to improving the flat grinding quality and the flat grinding efficiency. Optionally, the direction of rotation of the positioning grinder is opposite to the direction of rotation of the abrasive disc 325.

The conveying assemblies are sequentially arranged along the first direction, and a gap is formed between every two adjacent conveying assemblies so that the second stopping rod can extend to the top of each conveying assembly; in addition, a gap is also formed between adjacent delivery wheels 22 on each driven shaft 21 to facilitate the extension of the first blocking lever to the top of the transfer assembly.

The first rotary driving member includes a second rotary power element 23, a driving shaft 24 having an axis extending along a first direction, and a plurality of driving gears 25 coaxially disposed on the driving shaft 24, such that the plurality of driving gears 25 rotate with the driving shaft 24 about the first direction as a rotation axis. The driving gears 25 are engaged with the driven gears 20 of the conveying assemblies in a one-to-one correspondence manner, the second rotary power element 23 can drive all the driven rotating shafts 21 to rotate, and the power output by the second rotary power element 23 is transmitted to the conveying wheels 22 sequentially through the driving rotating shaft 24, the driving gears 25, the driven gears 20 and the driven rotating shafts 21, so that all the conveying wheels 22 synchronously rotate, and the conveying function of the conveying mechanism is realized. It will be appreciated that in order to change the direction of transmission, helical gears are used as the driving gear 25 and the driven gear 20.

Wherein, this kind of structure has the advantage of the steady power of practicing thrift of transmission, and adopts the conveying wheel 22 conveying, can reduce the colliding with to glass in glass transportation process.

The conveying assembly further comprises a separating part 26, the two conveying wheels 22 positioned in the middle of each conveying assembly are the separating conveying wheels 22, the separating conveying wheels 22 are provided with the separating parts 26, and the two separating conveying wheels 22 are respectively a first separating conveying wheel 22 and a second separating conveying wheel 22. The glass clamping mechanism 1 is arranged on one side of the first separating and conveying wheel 22, which is far away from the second separating and conveying wheel 22, so that the conveying mechanism on the side is used for a feeding channel of the glass 4 to be processed. Further, when the positioning conveying line 2 is applied to the flat grinding device 3, the conveying mechanism is positioned on one side, away from the first separating conveying wheel 22, of the second separating conveying wheel 22 and serves as a feeding channel of the processed glass, so that the glass can be classified and conveyed through the arrangement of the separating conveying wheels 22, and the utilization rate of the conveying mechanism is improved.
