Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport systems are inefficient in picking up and placing small rubber plugs into holes of workpieces due to limited precision and control over suction and placement mechanisms.
Innovation Solution
A transport system incorporating a cylinder, piston assembly, and suction nozzle coupled to a mechanical arm, where the piston assembly and suction nozzle work in conjunction with an air supply to precisely pick up and place rubber plugs by controlling suction pressure, ensuring accurate placement into workpiece holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional suction nozzle is used to pick up rubber plugs, then the structure is simple, but the precision and control over suction pressure are insufficient
Solution Approach 1:
The suction nozzle is divided into multiple independent chambers (first suction chamber, second suction chamber, third suction chamber) with separate piston assemblies and air supply channels. This segmentation allows independent control of suction pressure in each chamber, achieving precise control while maintaining a manageable structural complexity through modular design
Solution Approach 2:
The system employs movable piston assemblies within each suction chamber that can be dynamically adjusted to control the volume and pressure of the suction environment. The pistons can move independently to adapt suction force to different rubber plug sizes and requirements, providing dynamic pressure control without overly complicating the overall structure
2Force
If the suction nozzle presses directly on the rubber plug, then the picking up force is strong, but the rubber plug may be damaged
Solution Approach 1:
Different suction chambers have different cross-sectional areas and are designed for different types of rubber plugs. The first suction chamber with larger area handles larger plugs requiring stronger force, while smaller chambers handle smaller plugs with gentler suction, providing locally optimized force application that prevents damage
Solution Approach 2:
The elastic member is pre-installed between the piston and the suction nozzle tip to provide cushioning before contact. This elastic element absorbs excess force and prevents direct hard contact between the mechanical piston and the rubber plug, ensuring strong picking up force without damage
3Productivity
If the mechanical arm moves the transport quickly, then the productivity is high, but the placement precision decreases
Solution Approach 1:
The system uses periodic suction and release cycles controlled by the piston assemblies. During high-speed transport, the suction is maintained in a periodic manner, allowing the rubber plug to be securely held during movement and then precisely released when positioned, enabling both high speed and precision through rhythmic control

AI summary
A transport configured to cooperate with a mechanical arm to pick up and place rubber plugs, includes a housing, a piston assembly received in the housing and a pickup assembly. The pickup assembly includes a guide base and a pickup member. The guide base defines a second receiving cavity. The housing also defines a first receiving cavity coupling with the second receiving cavity. A first tracheal joint and a second tracheal joint are provided on the housing. The piston assembly is slidably received in the first receiving cavity and driven by the first tracheal joint. The piston assembly defines a channel coupling with the second tracheal joint. The pickup member includes a connecting portion and an ejection portion inserting through the connecting portion. The connecting portion is received in the second receiving cavity. The ejection portion defines an air vent.
