Description

Technical Field

[0001] The invention relates to the technical field of glass processing, and in particular to a lower sheet guiding mechanism for a glass substrate. Background Art

[0002] Glass substrates are key materials for flat panel displays. When processing, they need to be transported. At this time, the lower sheet guide mechanism is needed to drive the glass substrate for transmission. When the glass substrate needs to be placed vertically on the placement rack, the lower sheet guide mechanism drives the glass substrate to rotate to make it stand vertically, and then stands it on the placement rack.

[0003] Chinese patent CN2023207903865 discloses a lower sheet guiding mechanism, including a base plate, a limit block is fixedly installed on the left end of the upper outer surface of the base plate, a first fixed block is fixedly installed on the right end of the upper outer surface of the base plate, a first servo motor is arranged on one side of the limit block, and the lower outer surface of the first servo motor is fixedly connected to the upper outer surface of the base plate, a ball screw is arranged on the outer surface of one end of the first servo motor, a ball nut is arranged on the outer wall of the ball screw, a moving plate is arranged on the upper outer surface of the ball nut, and the middle part of the lower outer surface of the moving plate is fixedly connected to the upper outer surface of the ball nut, and a glass lower sheet assembly is fixedly installed on the upper outer surface of the moving plate. The lower sheet guiding mechanism described in the utility model has the advantages of lowering glass, being easy to move, and being easy to transfer glass at a farther distance.

[0004] However, the lower sheet guiding mechanism disclosed in the Chinese patent CN2023207903865 generally fixes the glass substrate through a suction cup structure. When the guiding mechanism drives the glass substrate to stand vertically, the staff is required to place the placement rack on the lower side of the glass substrate. When the suction cup stops suction, the glass substrate will quickly detach from the suction cup, and the glass substrate will be placed on the placement rack. Since the staff places the placement rack on the lower side of the glass substrate and there is a gap between the placement rack and the glass substrate, the glass substrate may fall onto the placement rack, which may easily cause collision and damage to the lower side of the glass substrate.

When the glass suction cup loses suction, the extrusion spring drives the extrusion slider to press the glass substrate. Due to the friction between the glass substrate and the extrusion slider, the glass substrate will slide down slowly on the glass suction cup, and the glass substrate slowly falls onto the placement rack, thereby avoiding the problem that the glass substrate is quickly dropped onto the placement rack when the glass suction cup loses suction, causing the glass substrate to be bumped and damaged, thereby improving the stability of the placement of the glass substrate and reducing the risk of glass substrate damage caused by unexpected situations.

[0017] In addition, by adopting a mobile lubrication mechanism, when the mobile base drives the glass substrate to slide, it drives the lubrication body to slide. The lubrication body cleans impurities on the guide rail to avoid the problem that impurities affect the sliding of the mobile base on the guide rail. At the same time, the lubrication body applies lubricating oil to the guide rail to ensure that the mobile base slides smoothly on the guide rail. BRIEF DESCRIPTION OF THE DRAWINGS
