Description

Technical Field

[0001] The utility model relates to the field of devices used for grinding, in particular to a flat coil side edge paint stripping machine. Background Art

[0002] A flat coil is an inductor coil wound with a flat copper-clad wire. The flat coil includes a coil portion and pin portions extending from both ends of the coil portion. The pin portions are bent in the direction of external circuit connection, and the surface of the coil portion and the pin portions are usually covered with an insulating varnish layer. The flat coil needs to go through multiple processes during production, including de-varnishing (paint stripping) on ​​both sides of the pin portions and tinning.

[0003] For this reason, there are devices for side stripping of flat coil pins in the prior art. For example, Chinese patent document CN218575858U discloses a side stripping device, which includes a base, an X-axis drive module, a positioning fixture, a Y-axis drive module, and a rotating friction assembly. The side stripping device drives the positioning fixture to reciprocate along the X-axis direction through the X-axis drive module, and drives the rotating friction assembly to reciprocate along the Y-axis direction through the Y-axis drive module, thereby stripping the side of the flat coil. However, the side stripping device lacks a structure for adjusting the verticality of the grinding rod of the rotating friction assembly. When performing the stripping operation, the grinding rod cannot be adjusted according to the situation to make it perpendicular to the side of the coil. When the grinding rod and the side of the coil cannot be guaranteed to be perpendicular, it will cause the side of the coil to be not ground cleanly or too much ground. Utility Model Content
