Description

Technical Field

[0001] This application belongs to the field of pad printing technology, and particularly relates to a pad printing device. Background Technology

[0002] Pad printing is a type of printing method that can print text, graphics, and images on irregularly shaped objects. Pad printing machines typically have a printing head made of silicone rubber. This head is dipped in ink with a pre-set printing pattern and pressed up and down on the corresponding position on the material to be printed, thus completing the printing process. Furthermore, to achieve automated, assembly-line processing, pad printing machines usually also have loading and unloading mechanisms.

[0003] Currently, during the pad printing process on the mobile phone frame, the ink position on the mobile phone frame is usually set perpendicular to the pad printing mechanism. If the ink position on the mobile phone frame deviates from the pad printing mechanism during the pad printing process, it will result in lower ink printing accuracy and may even affect the quality of the mobile phone frame.

[0004] Improving the accuracy of printing ink is a problem that urgently needs to be solved. Utility Model Content
