[0016] Further, a limiting groove is arranged on the upper surface of the positioning frame along the cup hole, and the limiting ring is embedded in the limiting groove for mounting. The cup body is circumferentially limited by the limiting groove, preventing the cup body from moving sideways during the pressing process of the punch, which may cause misalignment between the punch and the cup body, affecting the quality of the flux, and even damaging the cup body or the punch.

[0017] Further, the depth of the limiting groove is equal to the thickness of the limiting ring. The upper end of the cup body is in the same plane as the upper surface of the positioning frame, which facilitates the cleaning of the flux powder, so that the overflowed flux during the compaction of the filled flux or the punch can be recycled or refilled into the cup body by simple cleaning.

[0018] Further, the outer side wall of the punch matches the inner side wall of the cup body. Preventing the size of the outer side wall of the punch from being smaller than the size of the inner side wall of the cup body, which may cause incomplete compaction of the flux by the punch, or preventing the size of the outer side wall of the punch from being larger than the size of the inner side wall of the cup body, which may cause damage to the cup body when the punch is pressed down.
