Rotary Pickup Reciprocating Driving Unit Axial Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic components conveyor systems with rotary pickups face a limitation in arranging multiple reciprocating driving units due to physical interference, restricting the number of positions where holding portions can reciprocate, which hampers the ability to provide multiple processing functions without enlarging the rotary pickup, thereby losing the advantage of higher rotation speeds.
Innovation Solution
The electronic components moving apparatus features a reciprocating driving unit aligned at right angles to the rotational plane of the rotor, with a slide pusher and motor positioned to extend radially outward, allowing multiple positions for holding portion reciprocation without interfering with each other, even on a small-sized rotary pickup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If reciprocating driving units are arranged radially outward on a small-sized rotary pickup, then the number of reciprocating driving units is limited due to physical interference, but if the rotary pickup is enlarged, then more units can be arranged but the rotation speed advantage is lost
Solution Approach 1:
The reciprocating driving units are arranged in the axial direction (perpendicular to the rotational plane) rather than radially outward in the rotational plane. This dimensional change allows multiple driving units to be positioned at different axial locations without interfering with each other during rotation, enabling a higher density of reciprocating driving units on a small-sized rotary pickup while maintaining high rotation speeds.
2Adaptability or versatility
If multiple reciprocating driving units are arranged on a small-sized rotary pickup, then physical interference occurs between units, but if units are spaced out, then the density of processing functions is reduced
Solution Approach 1:
By transitioning from a two-dimensional radial arrangement to a three-dimensional arrangement utilizing the axial direction, the patent enables multiple reciprocating driving units to occupy different spatial positions without interfering with each other's reciprocating motion. This increases the density of driving units while avoiding physical interference.
Solution Approach 2:
The reciprocating driving units are designed to move dynamically in the axial direction during operation, allowing them to clear each other's paths during reciprocation. This dynamic motion resolution prevents physical interference between units that would occur if they were statically positioned in the same radial plane.
3Speed
If the rotary pickup is made small to maintain high rotation speed, then the space for arranging reciprocating driving units is limited, but if made large, then more units can be arranged but the speed advantage is lost
Solution Approach 1:
The patent utilizes the axial dimension (perpendicular to the rotational plane) to arrange reciprocating driving units, effectively adding a third dimension to the space available for processing operations. This allows multiple processing functions to be accommodated on a compact, small-sized rotary pickup without compromising rotation speed, as the units are distributed along the axial direction rather than requiring a larger radial footprint.

AI summary
An electronic components moving apparatus includes a rotor having a suction nozzle whose tip is oriented radially outwards. A reciprocating driving unit is placed for advancing the suction nozzle radially outwards of the rotor. The suction nozzle has a projecting portion. The reciprocating driving unit includes a slide pusher which is placed so as to slide radially outwards of the rotor and which is brought into abutment with the projecting portion to push out the suction nozzle and a rotating motor for the slide pusher. The slide pusher and the rotating motor are disposed so that the suction nozzle, the slide pusher and the rotating motor are aligned in a line along a rotational axis of the rotor when the suction nozzle stops in the position where the reciprocating driving unit is placed.
