Substrate conveying device

Abstract

The invention discloses a substrate conveying device and relates to mechanical equipment used in the displayer manufacturing process. The substrate conveying device aims to avoid shutdown of equipment. The substrate conveying device comprises a substrate conveying unit, a supporting unit and a driving unit. The substrate conveying unit is arranged in the horizontal direction, one end, in the horizontal direction, of the substrate conveying unit is a hinging end, and the other end of the substrate conveying unit is a free end; the supporting unit is located below the substrate conveying unit and is fixed; the driving unit is connected with the substrate conveying unit and is used for driving the substrate conveying unit to move in the vertical direction; when the substrate conveying unit descends, the bottom of the substrate conveying unit makes contact with the top of the supporting unit and rotates with the contact point of the substrate conveying unit and the supporting unit as the center so that the substrate conveying unit can incline. The substrate conveying device is mainly used for conveying substrates.

Description

technical field [0001] The invention relates to mechanical equipment used in the display manufacturing process, in particular to a substrate transmission device. Background technique [0002] In the manufacturing process of the liquid crystal display, the conveying of the substrate is an indispensable process, and the conveying device of the substrate plays the role of conveying the substrate. At present, in order to reduce costs and save space, the substrate transfer device adopts an upper and lower two-layer transfer structure, that is, the substrate transfer device transfers the substrate from the upper layer to the lower layer. The substrate is in a horizontal state when it is on the upper layer, and it is in an inclined state when it is transferred to the lower layer. [0003] Such as figure 1 As shown, the prior art substrate transfer structure includes a horizontally placed substrate transfer unit 10', one end 12' of the substrate transfer unit is a free end, the oth...

Problems solved by technology

[0004] However, the tilting action of the above-mentioned substrate transfer unit is realized by the cylinder, so as the use time increases, the frequency of abnormal occurrences of the cylinder increases, which is relatively easy to cause equipment downtime, and the cylinder and the cylinder support will undoubtedly increase the weight of the substrate transfer unit. Increase the bearing pressure of the drive unit, so that the drive unit is easier to damage, resulting in equipment downtime
