Axial Component Feed Hooks That Prevent Lead Bending on Return
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component supply devices concentrate load on leads during return, causing lead bending and reducing reliability in axial component mounting.
Innovation Solution
A component supply device with a feed mechanism featuring feed hooks of varying lengths and a moving mechanism that disperses load across multiple hooks during the return process, preventing lead bending and ensuring reliable axial component supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the feed member returns to the upstream side with uniform feed hooks, then the structure is simple, but the load concentrates on single lead causing bending and reliability reduction
Solution Approach 1:
The feed hooks are designed with asymmetric lengths where at least one feed hook has a different length from the others. This asymmetry allows the feed member to distribute the return load across multiple leads rather than concentrating it on a single lead, preventing lead bending and improving reliability while maintaining a relatively simple feed hook structure
2Reliability
If the feed hook length is uniform, then the manufacturing is easy, but the load distribution during return is uneven causing lead bending
Solution Approach 1:
The feed hooks are designed with different lengths tailored to their specific positions and functional requirements. By making each feed hook's length appropriate for its local role in load distribution, the design achieves both reliable component supply and reasonable manufacturing complexity

AI summary
A component supply device includes a transport path that guides a component connected body from a component insertion port on an upstream side in a component feeding direction to a component supply position on a downstream side, the component connected body including a plurality of axial components arranged and connected at a predetermined pitch, the plurality of axial components each having a lead, and a feed mechanism that pitch-feeds the component connected body along the transport path to the downstream side. The feed mechanism includes a feed member which has a plurality of feed hooks disposed at the predetermined pitch along the component feeding direction, a rotating shaft which is connected to one end side of the feed member, and a moving mechanism which is connected to the feed member through the rotating shaft and reciprocates the rotating shaft along the component feeding direction. A length of one feed hook among the plurality of feed hooks is longer than a length of an other feed hook among the plurality of feed hooks, the other feed hook being adjacent to the one feed hook on the rotating shaft side.
