Description

Inspection apparatus for display panel Technical Field The utility model relates to the technical field of manufacturing of display panels, in particular to inspection equipment of a display panel. Background In the process of manufacturing the display panel, an inspection apparatus is required to inspect the display panel, specifically, as shown in fig. 1 and 2, the inspection apparatus generally includes an air-floating conveyor 100 'and an inspection apparatus 200', wherein the air-floating conveyor 100 'includes a plurality of groups of first air-floating conveyor plates 11' arranged along a first direction S1', each group of first air-floating conveyor plates 11' includes at least four first air-floating conveyor plates 11 'arranged at intervals along a second direction S2', the first air-floating conveyor plates 11 'are used for ejecting air flow inclined along the first direction S1' through their own first air outlets for conveying the display panel along the first direction S1', the air-floating conveyor further includes two second air-floating conveyor plates 21', the two second air-floating conveyor plates 21 'are disposed between two adjacent groups of first air-floating conveyor plates 11', and the two second air-floating conveyor plates 21 'are arranged along a second direction S2', the length direction of the second air-floating conveyor plates 21 'is parallel to the second direction S2', the inspection apparatus is used for ejecting air flow inclined along the first direction S1 'through their own first air outlets for conveying the display panel along the first direction S1', the second air-floating conveyor plates 21 'are formed along the second direction S1' and the second air-floating conveyor plates 200 'are formed along the second direction, and the second air-floating conveyor plates 21' are formed along the second direction opposite directions, and the first air-floating conveyor plates are formed along the second direction, and the second air-floating direction and the air-floating direction are formed by the air-floating direction. In order to reduce the cost of the inspection apparatus, at least four first air-floating transfer plates 11' included in each group of first air-floating transfer plates 11' are arranged at intervals along the second direction S2', so that the distribution area of the air-floating effect of one group of first air-floating transfer plates 11' along the second direction S2' is larger, so that a more stable supporting and transferring effect can be provided for the display panel along the second direction S2', the two second air-floating transfer plates 21' are arranged along the second direction S2', and the length direction of the second air-floating transfer plates 21' is parallel to the second direction S2', so that the air-floating effect area of the second air-floating transfer plates 21' along the second direction S2' is suitable for covering each position of the display panel along the second direction S2', and meanwhile, the two second air-floating transfer plates 21' have less interval areas along the second direction S2', so that the display panel can be more stably supported. However, in the installation, the installation gap 210' is inevitably formed between the two second air-floating transfer plates 21', so that the air-floating supporting force of the display panel between the two second air-floating transfer plates 21' is small, the display panel is easy to generate concave bending towards the second air-floating transfer plates 21' at the middle part along the second direction S2', and the probability that the display panel collides with the air-floating transfer device 100' is increased and the manufacturing yield of the display panel is reduced in the process of transferring and inspecting the display panel by using the inspection device 200 '. Disclosure of utility model The utility model aims to provide a display panel inspection device which can effectively reduce the probability of collision of a display panel on an air-floating conveying device in the process of conveying and inspecting the display panel.
