JP-2026075991-A - Component mounting device

Abstract

[Problem] The objective is to provide a component mounting device that can suppress changes in the posture of the air filter within the air pipeline, thereby enabling accurate detection of air flow rate by a flow sensor. [Solution] The component mounting device is interposed between a tube 53 connected to a nozzle and a filter housing 36 connected to a pressure source, and comprises a pipe joint 41 that connects the tube 53 and the filter housing 36 via a communication passage 44 provided inside, and a bottomed, cylindrical air filter 50 attached to the pipe joint 41. The pipe joint 41 has an extension portion 42 that extends into the inside of the filter housing 36 and has a tip opening 42K, which is the opening of the communication passage 44, at its tip, and the air filter 50 is mounted so as to cover the extension portion 42 with its bottom portion 51 facing the tip opening 42K. The extension portion 42 has a convex portion 42T on its outer surface 42S that is pressed against the inner surface 50M of the air filter 50 and spreads the inner surface 50M of the air filter 50 outwards.

Description

This disclosure relates to a component mounting device for mounting components onto a substrate. The component mounting device is a device that mounts components onto a substrate positioned by the substrate transport unit. It is equipped with a mounting head that picks up components supplied by the component supply unit. The mounting head has a nozzle extending downwards, and by supplying negative pressure air to the nozzle, a suction force is generated at the lower end of the nozzle to attract components. A flow sensor is interposed in the air pipeline that introduces air to the nozzle. By measuring the flow rate of air flowing through the air pipeline using the flow sensor, it is possible to detect errors such as component suction failures by the nozzle. In such component mounting devices, an air filter is provided in the air pipeline to prevent damage to the flow sensor from foreign matter such as dust and debris contained in the air drawn in from the nozzle (for example, Patent Document 1 below). In Patent Document 1, a pipe joint (tube connection) is interposed between the nozzle-side air pipeline connected to the nozzle and the pressure source-side air pipeline connected to the pressure source. A communication passage (internal pipe within the tube connection) is provided inside the pipe joint, connecting the nozzle-side air pipeline and the pressure source-side air pipeline. The air filter (filter member) is mounted on an extension (projection) extending from the pipe joint into the pressure source-side air pipeline, covering the opening of the communication passage.
