Embodiment Construction
[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, a transmission device provided by the present invention will be described in detail below with reference to the accompanying drawings.
[0026] This embodiment provides a transmission device, such as figure 2 As shown, the transmission device includes a plurality of transmission shafts 1 arranged in parallel, each transmission shaft 1 is provided with at least one roller 2, the rotating mechanism (not shown in the figure) drives the transmission shaft 1 to rotate, and the transmission shaft 1 drives the above The rollers 2 are rotated so that the rollers 2 can horizontally transport the substrate 3 under the action of friction. The rollers 2 on each conveying shaft 1 form at least one roller row 4 in the conveying plane, and at least two rollers 2 in the roller row 4 are arranged alternately along the conveying direction. Specifically, in figure 2 Among ...

The invention provides a transmission device, a substrate transmission system and a substrate transmission method. The transmission device comprises a plurality of parallel arranged transmission shafts, at least one rolling wheel is arranged on each transmission shaft, at least one rolling wheel row is formed in the transmission plane by rolling wheels of the transmission shafts, and at least two rolling wheels in the rolling wheel rows are arranged in a crossed mode. When the transmission device transmits a substrate, the substrate surface is rubbed by at least two rolling wheels side by side in the rolling wheel rows, the number of rolling wheels rubbing on the same position on the substrate surface can be reduced, the damage degree of the same position on the substrate surface is reduced correspondingly, and flatness of the substrate surface is improved; and during thinning process of the substrate, etching uniformity of an acid-base etching solution on the substrate surface is improved, accordingly occurrence rate of poor appearance such as concave points, scratches produced on a display panel surface is reduced, and thus the production yield rate of display panels is improved.
Description
technical field [0001] The invention relates to the field of equipment manufacturing, in particular to a conveying device, a substrate conveying system and a substrate conveying method. Background technique [0002] In the manufacturing process of the display panel, it needs to go through various processes, such as: alignment layer process, rubbing process, box forming process, etc., and the substrate needs to be transported by a conveying device between each process. figure 1 It is a structural schematic diagram of an existing transmission device, the transmission device includes a plurality of transmission shafts 1 arranged in parallel, a plurality of rollers 2 are fixedly arranged on the transmission shaft 1, and a plurality of roller columns 4 are formed along a direction perpendicular to the transmission shaft 1, and each roller The individual rollers 2 in row 4 are aligned with each other. When the transmission device is working, the transmission shaft 1 drives the ro...
