Description

Technical Field

[0001] The utility model relates to the technical field of screen printing, in particular to a multi-window printing platform. Background Art

[0002] Screen printing is a printing technology that uses screen printing equipment to print a designed pattern on the product to be printed. Existing screen printing equipment at least includes a printing platform, a screen printing plate, and a scraper. The screen printing plate is provided with hollows according to the design pattern. When working, the substrate is placed on the printing platform, and the scraper pushes the ink through the screen printing plate. When the ink passes through the hollows on the screen printing plate, the scraper can press the ink through the hollows and adhere to the substrate to form a design pattern. The printing platform table absorbs the substrate through negative pressure, and uses a CCD camera to detect the substrate's position. In order to avoid the scraper and screen printing plate, the CCD camera is generally placed on the lower side of the printing platform table. Therefore, two linear alignment windows are opened on the printing platform table and covered with glass so that the CCD camera can detect the position of the substrate. Because the sizes of substrates are different, the window length will be made longer to be compatible with a variety of substrate sizes. This makes the glass cover on the window easy to break. In addition, this window structure detection product still has great limitations. The size of the substrate cannot be too small, and it is impossible to achieve completely accurate angle positioning for an irregular substrate.

[0003] Therefore, the prior art needs to be improved. Utility Model Content
