Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiments described by referring to the drawings are exemplary and intended to be used for explaining the present application and are not to be construed as limiting the present application. In the description of the present application, it is to be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the present application and for simplicity in description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated in a particular manner, and thus should not be considered limiting. Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise. In this application, unless expressly stated or limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can include, for example, fixed connections, removable connections, or integral connections; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate. In this application, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact of the first and second features, or may comprise contact of the first and second features not directly but through another feature in between. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly above and obliquely above the second feature, or simply meaning that the first feature is at a lesser level than the second feature.

As shown in fig. 1-4, the die for removing the waste from the corner side trimming of the OLED back plate comprises an upper die 1 and a lower die 2, wherein the lower die 2 is provided with a side cutting edge 3 for placing the OLED back plate and a side cutting punch 4 arranged on one side of the side cutting edge 3, the upper die 1 is provided with a slotting tool 5 for driving the side cutting punch 4, the upper die 1 is provided with a blowing device 6, and a blowing port of the blowing device 6 faces the side cutting edge 3 and is adjacent to the side cutting punch 4.

In order to solve the problem that the cut waste materials are adhered to the side cutting edge 3 or the side cutting punch 4, the blowing device 6, preferably a blowing pipe, is arranged at the position of the upper die 1, so that the side cutting punch 4 moves towards the position of the side cutting edge 3 under the action of the slotting tool 5 to cut the waste materials at the corner side of the OLED backboard, and then the waste materials are dropped under the action of the blowing device 6, and the waste materials are effectively prevented from being adhered to the position of the side cutting edge 3 or the side cutting punch 4.
