Dynamic Pushing Mechanism for Interference-Free Inspection Returns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inspection devices face inefficiencies due to interference on the conveying path when objects need to be returned after failing inspection, hindering the completion of return operations.
Innovation Solution
A pushing mechanism with a position-changing device, driving device, and guide device allows the pushing element to switch between states, ensuring objects are correctly positioned for inspection and efficiently returned without interference by adjusting its height and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pushing mechanism rotates to avoid interference on the conveying path, then the object can pass horizontally above the pushing mechanism, but the pushing mechanism obstructs the return path of the object when inspection fails
Solution Approach 1:
The pushing mechanism is designed to dynamically change its position between two states: a first state where it protrudes to push objects forward, and a second state where it retracts to allow object return. The driving device actuates the position-changing device to switch between these states, enabling the pushing mechanism to adapt its configuration based on operational requirements (conveying vs. return)
Solution Approach 2:
The position-changing device changes the spatial dimension of the pushing mechanism by moving it between different positions (protruding and retracted states). This dimensional change allows the pushing mechanism to clear the conveying path when retracted while maintaining pushing capability when protruded, resolving the conflict between forward conveyance and backward return operations
2Productivity
If the pushing mechanism maintains a fixed position to push objects, then the object can be pushed and corrected, but the object cannot be returned when inspection fails
Solution Approach 1:
The pushing mechanism transitions from a static fixed position to a dynamic system that can switch between two positions. The position-changing device enables this dynamic behavior, allowing the mechanism to be protruded during pushing operations for high productivity while being retracted during return operations to enable object retrieval, thus achieving both high pushing efficiency and return capability
3Ease of manufacture
If the pushing mechanism rotates back to initial position under own gravity, then the mechanism can move forward to push, but the object is obstructed during return operation
Solution Approach 1:
The system uses gravity-assisted automatic resetting combined with driving device actuation. When the driving device retracts the pushing mechanism, gravity helps it return to the initial protruded position automatically. This dynamic self-resetting mechanism reduces manufacturing complexity while enabling efficient return operations by ensuring the pushing mechanism is in the correct position for both pushing and returning objects

AI summary
A pushing mechanism and an inspection system are provided. The pushing mechanism includes a position-changing device (10), a driving device (20) and a guide device (30). The position-changing device includes a main plate (11) and a pushing element (12) movably disposed on a side of the main plate. The driving device is connected to the main plate and configured to drive the position-changing device to move. After the guide device is in contact with the pushing element, the pushing element may switch between a first state and a second state. A highest point of the pushing element in the first state is higher than a highest point of the pushing element in the second state. A highest point of the pushing element in the second state is lower than a highest point of the pushing element in the first state. At this point, the pushing mechanism may avoid interference on a conveying path of the object, so that a return operation may be completed by an inspection device, thereby improving the inspection efficiency of the inspection device.
