Description

Technical Field

[0001] The utility model relates to the field of tweezers, in particular to a pair of vacuum adsorption tweezers. Background Art

[0002] Tweezers are a tool used to pick up bulk medicines, metal particles, hair, thorns and other small objects. Tweezers can also be used to repair mobile phones, using them to clamp wires, components and integrated circuit pins. In the process of preparing battery electrodes, the punched electrodes are thin and easy to bend. During the transfer process, using tweezers to pick up the electrodes is likely to leave scratches, wrinkles or perforations on the electrodes, affecting the integrity of the electrodes. The removal operation is difficult and inefficient, which is not conducive to the production of button batteries. Utility Model Content
