Abstract
Official abstract text for this publication.
A suction nozzle, including a suction assistance section provided within an intake passage and connecting a side downstream of a pin and a side upstream of the pin, is provided. A cross section (the area of a cross section cut in a direction perpendicular to the direction in which the intake passage extends) of the intake passage is narrowed by the pin. Air bypasses the pin by flowing through the suction assistance section.
First claim
Opening claim text (preview).
1 . A suction nozzle for mounting an electronic component comprising: an intake passage in which negative pressure is applied such that an electronic component is picked up at a tip of the suction nozzle; a pin that cuts across the intake passage; and a suction assistance section provided in a wall surrounding the intake passage and connecting a downstream side of the pin and an upstream side of the pin within the intake passage. 2 . The suction nozzle for mounting an electronic component according to claim 1 , wherein the pin pierces a wall surrounding the intake passage such that an end of the pin protrudes outside, and the protruding end of the pin is used when integrating the suction nozzle with a nozzle holder. 3 . The suction nozzle for mounting an electronic component according to claim 1 , further comprising: a nozzle main body including the wall that surrounds the intake passage, a sleeve that stores the nozzle main body so as to be slidable along a direction in which the intake passage extends, and a pair of elongated holes provided in the nozzle main body along the direction in which the intake passage extends, wherein the pin is fixed to the sleeve, cuts across the intake passage, and is inserted into the pair of elongated holes. 4 . The suction nozzle for mounting an electronic component according to claim 3 , wherein the suction assistance section is a hole provided in the nozzle main body along the direction in which the intake passage extends and different to the pair of elongated holes. 5 . The suction nozzle for mounting an electronic component according to claim 3 , wherein the suction assistance section is provided as a pair in the nozzle main body, and, when looking at a cross section of the intake passage at a section where the pin cuts across the intake passage in a direction perpendicular to the direction in which the intake passage extends, the pair of elongated holes have two-way symmetry about the center axis line of the intake passage, and the pair of suction assistance sections are provided at positions rotated by 90 degrees from the pair of elongated holes about the center axis line of the intake passage.
