Carrier Device Sucker Alignment Using Preliminary Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing gripper and sucker alignment process in display assembly equipment results in low positioning efficiency due to reaction forces causing displacement, leading to multiple alignment attempts before successful gripping.
Innovation Solution
A carrier device with a positioning sucker mechanism and a sliding sucker mechanism, where a clamping assembly with mutually attracted suction pieces reduces displacement and improves alignment efficiency by using a rotating motor assembly and a main body with multiple suction planes, along with a driver to drive the clamping assembly and position the sucker mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gripper moves towards the sucker at a certain speed to achieve bonding, then the bonding function is achieved, but the collision between the gripper and sucker produces reaction force causing displacement and requiring multiple alignment attempts
Solution Approach 1:
The patent introduces a positioning block with a positioning groove that preliminarily guides and pre-positions the gripper before actual contact. The positioning groove receives the positioning block and guides the gripper's approach, ensuring accurate alignment before the gripping action occurs, thereby eliminating the need for multiple alignment attempts
Solution Approach 2:
The positioning block acts as an intermediary element between the gripper and the sucker. It includes a positioning groove that interfaces with the gripper's positioning protrusion, serving as a mediator to transfer and stabilize the positioning function, reducing direct collision and reaction forces
2Reliability
If multiple alignment attempts are made before successful gripping, then the sucker can be gripped, but the positioning efficiency is reduced
Solution Approach 1:
The positioning groove and positioning protrusion establish preliminary geometric constraints that guide the gripper into correct alignment before the gripping action. This preliminary positioning ensures that the first contact attempt is successful, eliminating repeated alignment cycles and reducing positioning time
3Ease of operation
If the gripper approaches the sucker with collision, then the sucker can be gripped, but displacement occurs due to reaction force
Solution Approach 1:
The positioning block serves as an intermediary that absorbs and distributes the collision forces. The positioning groove guides the gripper's approach and the positioning structure dampens reaction forces, preventing displacement and maintaining positioning precision during the gripping action
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 enhances the efficiency of the gripper gripping the sucker by minimizing displacement and improving connection stability, thereby increasing production efficiency in display assembly processes.
Implementation Method 1
a first suction piece provided on the positioning block; and a second suction piece provided on the clamping assembly, mutually attracted to the first suction piece
