Description

Separation mechanism

technical field

The present invention relates to a separation mechanism, in particular to a separation mechanism with non-uniform distribution of suction nozzles.

Background technique

In the display field, in order to prevent friction or impact between glass substrates during packaging and transportation of glass substrates, a spacer film is often placed between glass substrates to protect the glass substrates, but the glass substrates The inside of the packaging box often sticks to the spacer film due to problems such as static electricity and vacuum. Please refer to Figure 1 and Figure 2 for the separation mechanism currently used in liquid crystal module factories. Figure 1 shows a schematic diagram of the combination of the separation mechanism and the glass substrate in the prior art, and Figure 2 shows the separation mechanism in the prior art. Schematic diagram of nozzle distribution. The separation mechanism 1 has a plurality of groups of suction nozzles 2, wherein these suction nozzles 2 are connected with a vacuum supply device (not shown) through conduits with through holes, and when these suction nozzles 2 are connected with the glass substrate 4 and the spacer film 5 After the surface 41 of the assembly 3 is bonded, the multiple sets of suction nozzles 2 are evenly distributed on the surface 41 of the spacer film 4 of the assembly 3, and then vacuum is used to separate the spacer film 5 from the glass substrate 4 by the multiple sets of suction nozzles 2 of the separation mechanism 1. on separation. However, in actual use, the separation mechanism 1 will also lift up the glass substrate 4 when the suction spacer 5 rises, and the glass substrate 4 will drop due to gravity, causing the glass substrate 4 to break. Moreover, the larger the size, the more obvious the banding phenomenon, causing the glass substrate 4 to be broken and the machine to crash. This is mainly due to the fact that multiple groups of suction nozzles 2 are evenly distributed on the entire bonding surface, that is, the surface 41 of the spacer film 4, so that the surface of the entire assembly 3, that is, the surface 41 of the spacer film 4, is simultaneously stressed to cause the entire surface to be evenly stressed, then It is easy for the spacer film 5 to stick to the glass substrate 4 .

In view of this, the object of the present invention is to provide a separation mechanism, which uses the uneven distribution of the suction nozzles of the separation mechanism at the corners of the assembly to generate uneven force, so that the diaphragm begins to separate from the substrate before a corner or an edge , to reduce the phenomenon of sticking to the substrate due to uniform force when the diaphragm is pulled off.

In order to achieve the above object, the present invention provides a separation mechanism that uses vacuum adsorption to separate the substrate and the diaphragm, the diaphragm is attached to the substrate to form an assembly, the assembly has four edges, and the four edges form four corners .

Detailed ways

Please refer to Fig. 3 and Fig. 4, Fig. 3 is a schematic diagram showing the combination of the separating mechanism and the assembly according to the present invention, and Fig. 4 is a schematic diagram showing the first embodiment of the nozzle distribution of the separating mechanism according to the present invention. The separation mechanism 10 provided by the present invention uses vacuum suction to separate the substrate 14 and the diaphragm 15 . Wherein, the diaphragm 15 is attached to the substrate 14 to form the assembly 13, the assembly 13 has four edges 21, 22, 23 and 24, and the four edges 21, 22, 23 and 24 form four corners A1, A2, A3 and A4, ie edges 21 and 22 form corner A1, edges 22 and 23 form corner A2, edges 23 and 24 form corner A3, and edges 24 and 21 form corner A4. Wherein, the substrate 14 is, for example, a glass substrate. In this embodiment, description is made by taking the assembly as a cuboid as an example. After the separation mechanism 10 is combined with the assembly 13, at least one and at most three corners of the assembly 13 are provided with suction nozzles 12, and these suction nozzles 12 are vacuumed and act on the diaphragm 15, that is, the surfaces of the suction nozzle 12 and the diaphragm 15 are also That is, the surface 16 of the assembly 13 engages. That is to say, only one or two or three of the four corners A1 , A2 , A3 and A4 of the assembly 13 may have suction nozzles 12 . When there is only one corner of the assembly 13 with suction nozzle 12, the surface 16 of the assembly 13 will only be stressed at one corner after the vacuum is applied, that is, an uneven force distribution will be formed, so that the surface peeled off from the diaphragm 15 will be assembled. Starting from the corner of the surface 16 of the part 13 with the suction nozzle, the diaphragm 15 is separated from the substrate 14 . When there are two corners with suction nozzles 12, the surface 16 of the assembly 13 after vacuuming has two corners opposite or on the same side to be stressed, and the uneven force will also make the surface 16 peeled off from the diaphragm 15, that is, the assembly. Starting at the corner of the surface 16 of 13 with the suction nozzle, the membrane 15 is separated from the substrate 14 . Most preferably, when any three corners of the assembly 13 are provided with suction nozzles 12, these suction nozzles 12 on the separation mechanism 10 are distributed in a triangle, and these suction nozzles 12 are on the surface of the diaphragm 15 of the assembly 13 16 forms an uneven distribution, and the suction nozzle 12 forms an uneven force on the assembly 13 after vacuuming, and the force will also separate the diaphragm 15 from the substrate 14 from the edge of the interface of the diaphragm 15 . As mentioned above, because the stress is at the corners of the diaphragm 15 and the stress at its four corners is not uniform, so according to the difference in the included angle between the pulling force and the surface 16 of the diaphragm 15 when peeling off, the film The sheet 15 starts to separate from the substrate 14 before a corner or an edge, so that the two bonded objects, namely, the film 15 and the substrate 14 are separated smoothly. Preferably, the distance between the suction nozzle 12 and the two edges forming the corner where the suction nozzle 12 is located is 1 cm, for example, taking the suction nozzle 12 at the corner A2 as an example, the corner A2 is formed by edges 22 and 23, in order to achieve the best For the peeling effect, the distance between the suction nozzle 12 and the edge 22 and the edge 23 is 1 cm.

Please refer to FIG. 5 , which is a schematic diagram of a second embodiment of the nozzle distribution of the separation mechanism according to the present invention. In this embodiment, after the separation mechanism 10 is combined with the assembly 13, a pair of suction nozzles 12, 12' are provided corresponding to each corner where there are suction nozzles, so as to enhance the peeling force after the separation mechanism 10 and the assembly 13 are combined. Of course, multiple suction nozzles can also be provided corresponding to each corner where there are suction nozzles, which only needs to meet the stress of uneven distribution at the corners of the assembly 13, so that the diaphragm 15 starts to contact the substrate before a corner or an edge. 14 to separate. Other than that, the separation mechanism of this embodiment is the same as that of the first embodiment. Therefore, it will not be described here.

To sum up, the uneven distribution of the suction nozzles of the separation mechanism at the corners of the assembly generates uneven force, so that the diaphragm begins to separate from the substrate before a corner or an edge, and the force of peeling is used to replace the force of tearing off. force to reduce the phenomenon of sticking to the substrate caused by uniform force when the diaphragm is pulled off, thereby effectively avoiding the scrapping of the glass substrate and machine downtime, and the separation mechanism of the present invention is simple in design and does not need to increase costs.
