Component Supply Device Posture Maintenance During Lead Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In component mounters, the existing component supply devices often cause components with lead portions to become inclined during cutting, leading to posture changes that hinder the installing head's ability to pick up the components correctly.
Innovation Solution
A component supply device with a posture maintainer featuring grip members that extend in the traveling direction of the component holding tape to maintain the component's posture, combined with cutting members that intersect the lead portion, ensuring the component remains upright during cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the lead portion is cut by using cutting members arranged in a direction orthogonal to the traveling direction of the component holding tape, then the component can be separated from the holding tape, but the component becomes inclined and its posture changes
Solution Approach 1:
The posture maintainer is positioned upstream of the cutting members and maintains the component's upright posture before cutting occurs. By preliminarily securing the component's posture through the grip members, the system ensures that when the cutting members subsequently cut the lead portion, the component remains properly oriented and does not become inclined.
Solution Approach 2:
The posture maintainer acts as an intermediary device between the component holding tape and the cutting members. It provides a stabilizing function by gripping the component body with its grip members, preventing posture changes during the cutting process, and ensuring the component is properly positioned for subsequent handling by the installing head.
2Productivity
If the component posture is not maintained during cutting, then the cutting operation can be performed, but the installing head cannot pick up the component correctly
Solution Approach 1:
The posture maintainer performs the action of maintaining component posture before the installing head attempts to pick up the component. By preliminarily securing the component in the correct orientation during and after cutting, the system ensures that when the installing head arrives to pick up the component, it is already in the proper posture for reliable pickup and subsequent mounting.
3Manufacturing precision
If the grip members extend in the traveling direction of the component holding tape, then the component posture can be maintained during cutting, but the device complexity increases
Solution Approach 1:
The grip members are designed to perform multiple functions: they grip the component body to maintain posture, guide the component through the cutting zone, and support the component during separation from the holding tape. By making the grip members multi-functional, the system maintains component posture without requiring additional separate devices, thereby limiting the increase in overall device complexity.

AI summary
A component supply device includes a posture maintainer and a pair of cutting members. The posture maintainer includes a pair of grip members, each of which includes a tip end portion that extends in a traveling direction of a component holding tape. The posture maintainer maintains the posture of a component by gripping a body portion of the component having been supplied to a component supply position with the body portion interposed between the tip end portions of the pair of the grip members. The pair of cutting members cuts a lead portion of the component having been gripped by the pair of grip members with the lead portion interposed between the pair of cutting members in a direction intersecting a traveling direction of the component holding tape.
