Description

Plate separation device and plate body separation method

The invention relates to a separation device and a separation method, in particular to a plate separation device and a plate separation method.

Electronic products with displays are indispensable for modern people, whether they are in work processing, learning or personal entertainment, including smart phones, tablets, notebooks, and monitors. (Monitor) to TV (TV) and many other related products. However, in addition to pursuing the electronic characteristics of electronic products themselves, such as high display quality, faster response speed, long service life and high stability, etc., consumers are also expecting electronic products to be more functional. Rich and diverse. In particular, consumer expectations for portable electronic products include whether electronic products are lighter and more portable in appearance.

Therefore, in order to make the appearance of such an electronic product thinner and lighter, the internal display device needs to achieve further thinning requirements. Therefore, it is also necessary to consider directly making the components inside the display device as thin as possible. For example, a glass substrate having a thickness of less than 0.5 mm can be used for manufacturing a display device.

Generally, a thin display panel is manufactured by first fixing a glass substrate on a carrier, and then performing processing on a corresponding display element on the glass substrate. After the corresponding display elements on the glass substrate are finished After the assembly, the display panel is further assembled to form a display panel, and then the carrier is separated from the glass substrate to complete the preparation of the thin display panel.

It should be understood that in the process of separating the carrier tray from the glass substrate, an external tension is applied to the carrier tray to separate the carrier tray and the glass substrate bonded to each other. However, in the process of separating the carrier disk from the glass substrate, the carrier disk often has a stress concentration phenomenon due to uneven application of the applied tensile force. When the stress is concentrated on the carrier plate and larger than the bending resistance of the carrier disk, the carrier disk may be broken, thereby affecting the yield of the thin display panel.

However, it is possible to avoid a situation in which the first plate body 210 is broken due to excessive stress. It should be understood that, in this embodiment, the suction hole 128 may be externally connected to the suction device (not shown) and generate suction of the vacuum suction through the activation of the suction device to adsorb the approaching first plate 210 to the adsorption plane 122a. , but not limited to this.

On the other hand, since the adsorption plane 122a of the present embodiment has the first corner 123a and the second corner 123b opposite to each other, the moving suction unit 124 is sequentially away from the carrying platform from the first corner 123a toward the second corner 123b. 110 drives the first plate 210 close to the adsorption plane 122a. Meanwhile, the number of the perforations 126 in a unit area on the adsorption plane 122a of the present embodiment decreases from the first corner 123a toward the second corner 123b, that is, It is said that the adsorption plane 122a has a mobile suction unit 124 having a relatively dense density at a position close to the first corner 123a. Therefore, in the embodiment, the first plate 210 can be separated from the second plate 220 from the corner 210a of the first corner 123a of the adsorption plane 122a, and the corner 210a of the first plate 210 At the same time, it can be pulled by more moving suction units 124 to be more easily separated from the second plate 220.

The adjacent two through holes 126 have a second spacing I2 therebetween, and each of the second spacings I2 is greater than each of the first spacings I1. In addition, the first direction D1 of the present embodiment is a direction parallel to the third side 125c or the fourth side 125d. In the present embodiment, the moving suction unit 124 is closely arranged at a position immediately adjacent to the first side edge 125a and the second side edge 125b, and at the same time, the moving suction unit 124 is also at the center of the first side edge 125a and the second side edge 125b.

A method for separating a plate body, comprising: providing a composite plate body comprising a first plate body, a second plate body, a third plate body and a fourth plate body connected to each other in sequence; carrying the fourth plate Providing a separation device, the separation device is located above the support platform, the separation device comprises: a separation platform having an adsorption plane, a plurality of perforations and a plurality of suction holes facing the adsorption plane Carrying a platform, and the perforations and the suction holes are formed on the adsorption plane at intervals; and a plurality of mobile suction units are respectively disposed in the perforations; and the mobile suction units are activated to move toward the support platform to be exposed to The perforations are attracted to the first plate; when the moving suction units are attracted to the first plate, the moving suction units are activated to move away from the carrying platform in a first direction to drive the first plate. The body is adjacent to the adsorption plane such that the first plate body is separated from the second plate body and the first plate body is sequentially adsorbed by the suction holes adjacent thereto; the second plate body connected to each other is turned over, The three-plate member and the fourth plate member; Carrying the second plate body on the carrying platform; starting the moving suction unit to move toward the carrying platform to expose the through holes to adsorb the fourth plate; and when the moving attraction units adsorb the fourth plate And driving the moving suction units to move away from the carrying platform in the first direction, and driving the fourth board to be close to the adsorption plane, so that the fourth board is separated from the third board and the fourth The plate body is sequentially adsorbed by the suction holes adjacent thereto. The method of separating a panel according to claim 15, wherein the composite panel further comprises a display unit between the second panel and the third panel.
