Non-overlapping Rotary Pickups for Compact Electronic Component Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transfer apparatuses with multiple rotary tables face a trade-off between downsizing and increasing the number of process points, leading to physical obstacles and increased space requirements, which limits the installation of process points and rotation speed.
Innovation Solution
A transfer apparatus with non-overlapping small-size rotary pickups arranged vertically, where each pickup intermittently rotates to transfer electronic components between adjacent units, forming a circular arc carrying path and allowing for increased process points without overlapping, thus reducing the necessary installation space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple rotary tables are installed vertically with overlapping outer circumferences to form a single carrying path, then the number of process points can be increased, but the apparatus size and installation space increase
Solution Approach 1:
The patent transitions from vertical stacking of rotary tables to horizontal arrangement of rotary pickups. Multiple rotary pickups are arranged side-by-side in the horizontal direction, with their rotation axes parallel to each other. This dimensional change eliminates the need for vertical overlap, reducing installation space while maintaining the capability to accommodate multiple process points through the horizontal expansion of the system.
Solution Approach 2:
The patent divides the single large rotary table into multiple smaller rotary pickups. Each rotary pickup handles a portion of the carrying path, and they work cooperatively to transfer electronic components. This segmentation allows the system to achieve the same functional capacity as a large rotary table but with reduced individual component sizes and optimized space utilization through horizontal arrangement.
2Ease of operation
If rotary tables are installed vertically with overlapping circumferences, then process points can be arranged on a straight line, but physical obstacles are created that limit the installation of additional process units
Solution Approach 1:
The patent changes the arrangement from vertical stacking to horizontal positioning of rotary pickups. The carrying path is formed by the outer circumferences of multiple rotary pickups arranged horizontally, eliminating physical obstacles created by vertical overlap. This allows process units to be installed at various positions along the horizontal carrying path without interference from overlapping table structures.
3Quantity of substance
If large-size rotary tables are used to accommodate multiple process points, then the number of process points increases, but the rotation speed decreases due to increased weight and size
Solution Approach 1:
The patent segments the large rotary table into multiple smaller rotary pickups. Each rotary pickup has reduced weight and size compared to a single large rotary table, enabling faster rotation speeds. The system maintains the capability to handle multiple process points by coordinating multiple lightweight rotary pickups horizontally, achieving both high process point capacity and high rotation speed.
Solution Approach 2:
The patent changes the physical parameters of the rotary components from large and heavy to small and lightweight. By using multiple small rotary pickups instead of one large rotary table, the system achieves higher rotation speeds while maintaining the functional capacity to accommodate multiple process points through horizontal arrangement and cooperative operation.

AI summary
This apparatus includes a carrying path for an electronic component, a holder unit holding and releasing the electronic component, and N number of rotary pickups including the multiple holder units, and intermittently rotating around the rotation axis. At least one of the rotary pickups is a first carrying structure. The rotary pickup adjacent to the first carrying structure is a second carrying structure installed so as to not overlap with each other, to have the respective rotation axes orthogonal to each other. The holder unit of the first carrying structure and that of the second carrying structure are each a sucking nozzle. The holder units of the first carrying structure and of the second carrying structure have a common stop position, and the electronic component is transferred at only a transfer point that is the stop position.
