Electronic circuit component mounting head

Abstract

The mounting efficiency of the electronic circuit components on the circuit base material can be kept high, and the damage caused by the abutting impact of the electronic circuit components and the suction nozzle or the circuit base material can be avoided. A rotating lift shaft (14) is held on the head body (12) in a manner capable of rotating and moving up and down, and a suction nozzle (22) is held on the rotating lift shaft (14) in a manner that can be relatively raised and lowered but not relatively rotated. The suction nozzle (22) is forced upward by the force applying unit relative to the rotating lifting shaft (14). In addition, the lift drive member (62) is held on the head main body (12) in a liftable manner, and is raised and lowered by the first linear motor (18). Engage the first engaging portion (64) of the lifting drive member (62) with the rotating lift shaft (14), and on the other hand, make the first engaging portion (64) of the second linear motor (60) held by the lifting drive member (62) The two engaging parts (66) are engaged with the suction nozzle (22), so that the suction nozzle (22) and the rotating lifting shaft (14) are lowered together, and the suction nozzle (22) is relatively rotated against the force of the force applying unit. The lift shaft (14) is lowered, and the component (86) is mounted on the circuit substrate in this state.

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, etc., which hold the nozzle for lifting and lowering, are raised and lowered by the second lifting drive device, the mass to be raised and lowered is relatively large. Elastic body, so the abutment of the nozzle and the object cannot be sensitively detected, due to at least one of the above two points, it is difficult to sensitively control the second lifting drive device, and it is difficult to sufficiently reduce the abutment impact
