Solution Overview
Problem
Existing electronic component alignment systems face challenges with precision and durability due to increased force exertion on components during testing and thermocompression, leading to abrasion and deformation of components like air bladders and guiding rods.
Innovation Solution
An alignment platform comprising a stationary plate, an active plate, rotation members, driving apparatuses, and connecting members, where the driving apparatuses, connected to motors and reducers, drive rotation members to move the active plate for precise electronic component alignment, eliminating the need for floating mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If floating mechanisms (air bladders, sliding members, guiding rods) are used for alignment, then electronic components can be moved to the right position, but the components become abraded and deformed due to increased force exertion during testing and thermocompression
Solution Approach 1:
The patent removes the floating mechanism components (air bladders, sliding members, guiding rods) from the alignment system. Instead of using these intermediate floating elements, the invention directly connects the driving apparatus to the electronic component holder, eliminating the sources of abrasion and deformation while maintaining alignment precision through direct mechanical coupling.
2Measurement precision
If floating mechanisms with sliding members and guiding rods are used, then alignment can be achieved, but the structure becomes complex and maintenance costs increase
Solution Approach 1:
The patent extracts and removes the complex floating mechanism subsystems (air bladders, sliding members, guiding rods) from the alignment system. The simplified design uses a direct mechanical connection between the driving apparatus and the component holder, significantly reducing structural complexity while maintaining alignment functionality.
Solution Approach 2:
Instead of using a floating mechanism where the component floats above the support structure, the patent inverts the approach by providing direct mechanical support and alignment through the driving apparatus connection, eliminating the need for intermediate floating elements and their associated complexity.
3Ease of operation
If air bladders and sliding members are used for alignment, then components can be positioned, but abrasion occurs due to pressure and sliding during each process
Solution Approach 1:
The patent removes the air bladders and sliding members that cause abrasion through pressure and sliding. The direct mechanical connection eliminates these harmful friction and pressure effects while maintaining the ease of component positioning through the driving apparatus.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides higher precision, reduced maintenance and manufacturing costs, a thinner structure, longer lifespan, and improved durability by precisely aligning electronic components without the need for sliding members or air bladders, thus preventing misconnection and extending maintenance periods.
Implementation Method 1
The driving apparatus includes a motor and a reducer. The reducer is connected to the motor and the rotation member therebetween so that the motor drives the rotation member to rotate via the reducer.
Implementation Method 2
The rotation member has an axis for rotation and an eccentric axle. The driving apparatus is adapted for driving the rotation member to rotate around the axis to make the eccentric axle rotate around the axis.
Implementation Method 3
The connecting member has a first connecting portion and a second connecting portion. The first connecting portion is connected to the active plate to make the active plate move following the first connecting portion. The second connecting portion is pivotally connected to the eccentric axle.

AI summary
The present invention reveals an alignment platform for aligning electronic component precisely to the operation position during testing or hot pressing processes. The alignment platform makes a rotor to rotate by a driving apparatus. The rotor has an eccentric axle to where a connecting member is disposed. The connecting member is moved by the eccentric axle, driving an active plate to move. The eccentric axle, the driving apparatus, the connecting member, and the active plate are configured to move under control in a micro or nano meter scale. Thus, precisely alignment of electronic component can be achieved. Floating mechanism of electronic component transmission apparatus or electronic component handler may be dismissed for lowering cost and prolonging lifetime.
