The invention discloses a capacitor metal spraying machine with an infrared ray distance measurement function, relates to production equipment of an electronic element, and particularly relates to production equipment of a capacitor. The capacitor metal spraying machine is characterized in that a T-shaped bracket (2) is provided with a plurality of circular discs (3); a working region (31) with adjustable size is arranged in each circular disc (3); the working region (31) and the corresponding circular disc (3) are concentric circles; an infrared ray distance measurer (1) is placed on the exteriors of the circular discs (3); the maximum metal spraying distance (L2) refers to a distance from the center of the working region (31) to the infrared ray distance measurer (1); and the distance from the infrared ray distance measurer (1) to the edge of the working region (31) is a measurement distance (L1). By adoption of the capacitor metal spraying machine, the distance measurement precision can be improved, error can be reduced, set frequency can be reduced, working intensity can be lowered, set error rate can be reduced, and production efficiency can be improved.
