Description

Technical Field

[0001] The utility model relates to the technical field of screen printing, in particular to a screen printing plate exposure device for a screen printing machine. Background Art

[0002] Screen printing refers to using a silk screen as a base plate and making a silk screen printing plate with images through a photosensitive platemaking method. During the use of a silk screen printer, the silk screen needs to be exposed to form a shadow on it so that it can be printed. The screen exposure device is an automatic exposure device that can be used for exposure, silk screen and other printing plates. The operation is quite simple, and the exposure light source uses a fast-start gallium iodine lamp. The spectral distribution is consistent with the characteristics of the printing plate, and with the help of a stable vacuum device system, the exposure speed is fast and the quality is high.

[0003] A screen printing machine is a machine that uses a screen printing plate to print, and is a type of printing machine. A screen exposure device is an automatic exposure device that can be used for exposure, such as screen printing plates. When the exposure device is not in use, dust may scatter on the surface of the placement table, and the accumulation of dust will affect the lighting effect of the screen plate. Therefore, the surface of the placement table needs to be cleaned before exposure. However, the existing exposure device does not have a cleaning function, and the staff needs to wipe and clean the placement platform with tools, which increases the workload of the staff. At the same time, the cleaning range cannot be guaranteed, and residues or neglect may occur, which will affect the exposure effect.

[0004] When using a plate exposure device, the screen plate needs to be placed on the surface of the placement table, and the screen plate needs to correspond to the bottom lighting position. However, existing plate exposure equipment generally directly places the photosensitive plate on the surface of the placement table, which is inconvenient for positioning the screen plate. It may cause displacement and crooked printing, which will lead to poor plate exposure effect and require re-operation, reducing work efficiency. Utility Model Content
