[ technical field ] A method for producing a semiconductor device

The utility model relates to an auxiliary tool of self-adaptation silk screen printing curved surface bill-board.

[ background of the invention ]

Some advertising panels have a convex curved surface structure, as shown in fig. 7, when printing advertising patterns and advertising characters, a silk-screen mold having a curved surface structure corresponding to the curved surface of the advertising panel needs to be manufactured, the silk-screen mold is usually made by splicing rigid plates (wood, steel or rigid plastic plates) into a mold frame having a fixed shape according to the shape and size of the curved surface of the advertising panel, and then a silk-screen net is fixedly connected to the arc-shaped bottom surface of the mold frame, and the shape of the silk-screen net is determined by the arc-shaped bottom surface of the section mold, so that the silk-screen net forms the curved surface corresponding to the advertising panel. During screen printing production, the curved surface of the billboard is placed upwards, a screen printing mold is placed on the curved surface of the billboard from the top, and screen printing is carried out by scraping ink on a screen printing net. Usually, a billboard corresponds to a set of silk-screen mould, and since the number of the same billboard is usually one or a few, the production cost is considered, and the production of the mould frame is usually carried out by adopting wood. Each billboard needs to customize a mold frame corresponding to the shape of the billboard, and the billboard has long manufacturing period and cannot be supplied quickly. The curved-surface type advertising board is usually manufactured in small batches and in various types, and the consumable material of the die frame is serious. In addition, because the manufacturing quantity of the advertising boards with the same curved surface is small, manual silk-screen printing is generally adopted, namely, a silk-screen mould is manually carried up to be placed on the corresponding advertising board, a silk-screen net is attached to the curved surface of the advertising board, the position of the silk-screen mould on the advertising board is adjusted, then ink is manually applied to the silk-screen mould, a sweeping brush is grabbed by hands to scrape the ink along the curved surface for silk-screen printing, and after the silk-screen printing is finished, the silk-screen mould is carried down from the advertising board. And the printing ink has volatility and irritability, and during production, printing ink volatility pungent smell is to the air, and the staff all need wear the gauze mask usually, and because the intensity of labour when silk screen printing work is great, the staff all needs breath widely often, and wear the gauze mask and also can not completely isolate and inhale these pungent smells, wear the gauze mask and also bring staff's discomfort when breathing vigorously.

The present invention is made based on such a situation.
