Description

Technical Field

[0001] The utility model relates to the technical field of NdFeB surface cleaning, in particular to a device for automatically cleaning the surface of NdFeB. Background Art

[0002] NdFeB magnet groups are formed by gluing multiple magnets together. During the production process, there are offset prints or foreign matter on their surfaces, and they need to be cleaned. Generally, this is done by manually wrapping a copper sheet with a dust-free cloth dipped in alcohol and wiping the surface of the product to remove foreign matter and offset prints on the surface of the product. However, there may be omissions in the manual cleaning process, resulting in omission of wiping the clean surface. There is also the problem of excessive force during manual wiping, which may cause breakage at the bonding joints of the NdFeB magnet group. In order to improve the stability and wiping effect of wiping cleaning, a device that can automatically clean the surface of the NdFeB magnet group is needed to avoid the influence of human action, which is why this case arises. Utility Model Content

The alcohol nozzle is located above the dust-free cloth and is used to spray alcohol toward the dust-free cloth. A wiping head is installed on the bottom side of the pressure head device. There is no magnetic attraction between the wiping head and the NdFeB magnet group. The pressure head device can drive the wiping head to move downward, so that the wiping head presses down the dust-free cloth and fits it to the top surface of the NdFeB magnet group. The slide drives the fixture to slide back and forth horizontally, so that the dust-free cloth wipes the surface of the NdFeB magnet group back and forth.
