Description

Technical Field

[0001] The utility model relates to the technical field of IC packaging tube processing equipment, in particular to an IC packaging tube marking tool. Background Art

[0002] An integrated circuit (IC) is an electronic device or component. An IC packaging tube is a tube used to package electronic components. Its main function is to prevent damage to electronic components during transportation and to prevent static electricity from causing electrostatic damage to electronic components during transportation and turnover. After the IC packaging tube is processed and formed, it is necessary to print and mark the processed packaging tube so that the corresponding parameter information of the IC packaging tube and the IC parameter information that can be accommodated are marked on the surface of the tube body, so as to facilitate the subsequent classification, storage and screening. At present, the commonly used printing method is ink dyeing. This method makes a micro-porous plate for the content to be transferred. The prefabricated flexible printing plate is rotatably connected to the support rod on the workbench, and then the packaging tubes to be transferred are arranged on the printing table in sequence. The flexible printing plate rotates around the support rod so that the flexible printing plate covers each packaging tube on the printing table, and the ink is applied to the outer side of the flexible printing plate. The ink on the flexible printing plate is transferred to the corresponding position of the packaging tube through the micro-pores through the scraper.

[0003] However, after the traditional ink dyeing method completes the printing process, the dyeing mark cannot be dried and solidified quickly due to the partial accumulation of ink transferred from the flexible printing plate. In particular, the marking area with a large amount of ink is prone to unnecessary diffusion of ink, resulting in blurred marking contours. In the process of grabbing and transporting the packaging tube, the ink that is not completely solidified is prone to sliding, further expanding the contaminated area, thereby causing ink contamination to the surface of the packaging tube, dyeing and printing equipment and auxiliary tooling. As a result, conventional ink dyeing and printing also need to consider adding additional drying tooling or extending the conveying structure to extend the natural drying time. The above methods will not only reduce processing efficiency, but also increase the printing cost and printing cycle, and the printing effect is not good, and there are problems of poor processing quality and low yield. In addition, the existing printing equipment does not clean the printing surface of the packaging tube to be processed. When there are impurities and other obstructions on the surface of the packaging tube, it is easy to cause the printing lines to be unclear or discontinuous, resulting in incomplete printing information and poor printing quality.
