Electronic-circuit-component-mounting head

Abstract

The present invention makes it possible to avoid damage caused by contact impact with an adsorption nozzle or a circuit substrate, while maintaining high mountability of an electronic-circuit component to the circuit substrate. A rotating-rising / falling shaft (14) is held in a head body (12) so as to be capable of rotating and rising / falling, and an adsorption nozzle (22) is held onto the rotating-rising / falling shaft (14) so as to be relatively capable of rising / falling and incapable of rotating. A biasing means biases the adsorption nozzle (22) upward in relation to the rotating-rising / falling shaft (14). In addition, a rising / falling drive member (62) is held in the head body (12) so as to be capable of rising and falling, and is raised and lowered by a first linear motor (18). A component (86) is mounted to a circuit substrate in a state in which: a first engaging part (64) of the rising / falling drive member (62) engages the rotating-rising / falling shaft (14), while the second engaging part (66) of a second linear motor (60) held onto the rising / falling drive member (62) engages the adsorption nozzle (22); and the adsorption nozzle (22) is lowered along with the rotating-rising / falling shaft (14), and the adsorption nozzle (22) is lowered in relation to the rotating-rising / falling shaft (14) in opposition to the biasing force of the biasing means.

Description

technical field [0001] The present invention relates to an electronic circuit component mounting device (hereinafter, unless otherwise required, simply referred to as a component) that holds an electronic circuit component (hereinafter, simply referred to as a component) on a circuit base material by a component holder such as a suction nozzle (hereinafter, unless otherwise required) The electronic circuit component mounting head (hereinafter, if there is no special need, is simply referred to as the mounting head), especially relates to a circuit substrate when the component is relatively fragile and is in contact with the component holder. A mounting head capable of suppressing the impact of contact (hereinafter, simply referred to as the impact of contact unless otherwise required) is easy to break when it is abutted against and can be mounted efficiently while suppressing the impact of contact. Background technique [0002] Patent Document 1 below describes a mounting de...

Problems solved by technology

For example, there are problems as follows: Since the nozzle holding shaft and the like that hold the nozzle to be raised and lowered are raised and lowered by the second lifting device, the mass to be raised and lowered is relatively large, and in addition, since the force sensor and the nozzle are interposed by elastic Therefore, it is impossible to detect the abutment of the suction nozzle and the object sharply. Due to at least one of the above two points, it is difficult to control the second lifting device sensitively, and it is difficult to sufficiently reduce the abutment impact.
