Description

Carrying overturning platform

technical field

The invention relates to a load-carrying flip platform, in particular to a load-carry flip platform suitable for carrying glass substrates in the production process of liquid crystal panels, which can carry glass substrates of different specifications, avoid scratches on the surface of the glass substrate, and reduce the number of glass substrates. Scrapped load-carrying overturning platform.

Background technique

During the manufacturing process of the liquid crystal panel, when the glass substrate of the liquid crystal panel is moving, as shown in Figure 1a, when the glass substrate needs to be moved from the conveyor belt 10 on the left to the conveyor belt 10' on the right, it needs to Use to carry turning platform 14. Also as shown in FIG. 1 b , when the glass substrate 16 needs to be moved from the working platform 12 on the left side of the figure to the working platform 12 ′ on the right side of the figure, the loading and turning platform 14 is also required. Similarly, as shown in Figure 1c and Figure 1d, when the glass substrate 16 will be moved from the conveyor belt 10 on the left side of the figure to the working platform 12 on the right side of the figure, or when the glass substrate 16 will be moved from the working platform on the left side of the figure 12, when moving to the conveyor belt 10 on the right as shown in the figure, it is necessary to carry and turn over the platform 14 to move.

Please refer to FIG. 2 , illustrating the existing load-carrying turning platform.

As shown in Figure 2, a load-bearing turning platform 20 includes a rotating shaft 21 and a platform 23, which are connected with the rotating shaft 21 in a rotatable manner to support the glass substrate 29. There are a plurality of holes 233 on the surface of the platform 23, and the platform is provided with A gas channel 25 communicates with the hole 233 on the surface of the platform 23 , and the gas channel 25 is connected with a valve switch 27 .

When the glass substrate 29 is to be loaded and transported, the glass substrate 29 is placed on the platform 23, the valve switch 27 is opened and vacuumized so that the glass substrate 29 is adsorbed on the platform 23, the valve switch 27 is closed to keep the vacuum in the gas channel 25, and the load is turned over The platform 20 can move together with the glass substrate 29. After the glass substrate 29 is transported to a predetermined position, the valve switch 27 is opened to return the air pressure in the air channel 25 to atmospheric pressure, and then the glass substrate 29 is separated from the platform 23.

As can be seen from Fig. 2, the area of the platform 23 is greater than the area of the glass substrate 29. In the process of handling, since the edge of the glass substrate 29 has burrs produced during cutting, after the edge of the glass substrate 29 contacts the platform 20, it will Glass debris (chip) is left on the platform 20, and this glass debris will pollute the next glass substrate 29 that needs to be transported, causing scratches on the surface of the glass substrate 29, scratches on the circuit on the glass substrate 29, and sometimes lead to Discarding of the glass substrate 29 .

To solve the above problems, it is necessary to replace the appropriate platforms of different sizes corresponding to glass substrates of different specifications and sizes, but this will cause waste of manpower and working hours.

Before the carrying and turning platform 20 transports the glass substrate 29, there are several preparatory actions. First, a layer of adhesive tape must be pasted on the entire platform 23 , the purpose of which is to provide a protective effect and reduce the damage caused by the platform 23 to the glass substrate 29 when the glass substrate 29 contacts the platform 23 . Another purpose is to seal the holes that do not need to be pumped.

As shown in FIG. 2 , the area of the platform 23 is larger than that of the glass substrate 29 . When in a manufacturing process, the glass substrate 29 used is a small size, the corresponding size of the glass substrate 29 on the platform is covered with a layer of adhesive tape within this range and the holes 233 are opened. When the platform 23 transports the glass substrate 29 , the valve switch 27 controls the suction to pass through the openings 233 so that the glass substrate 29 is adsorbed on the platform 23 . And when the specification and size of the glass substrate 29' used in the next production process is greater than the specification and size of the glass substrate 29 in the aforementioned production process, similarly, on the platform corresponding to the specification and size of the glass substrate 29', stick it within this range. The holes 233 covered with a layer of adhesive tape are perforated, so that when the platform 23 carries the glass substrate 29 ′, the valve switch 27 controls the suction to make the glass substrate 29 ′ adsorb on the platform 23 through the holes 233 of each perforation.

After the above-mentioned manufacturing process is completed, if the size of the glass substrate to be transported in the next manufacturing process is smaller than the size of the glass substrate 29' in the aforementioned manufacturing process, then it is necessary to remove all the tapes on the platform 23 and re- Apply a new layer of adhesive tape, and then open the hole 233 covered with a layer of adhesive tape on the platform corresponding to the size of the glass substrate 29, and repeat this tedious and complicated work. In this way, not only a large amount of adhesive tapes are used, but also manpower and man-hours are consumed in removing and pasting the adhesive tapes.

As mentioned above, it is necessary to stick the adhesive tape, open the hole 233 according to the size of the glass substrate, remove the tape, etc., because if the hole does not correspond to the size of the glass substrate, the hole will be opened When the range is larger than the area of the glass substrate, during the transportation process, since the valve switch 27 will be opened to pump air, and the action of the platform 23 will not only translate but also flip, at this time, the open hole will cause disturbance due to the air pump, and the local Large airflow variation in the range will cause difficulties in handling glass substrates.
