Guided Approach Device for Test Head Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing docking systems for test heads and handling devices in electronic component testing require manual alignment and precise positioning by two operators, making the connection laborious and inefficient, especially due to the high dead weight and inertness of the test heads, which complicates optimal alignment and linear alignment of locking pins.
Innovation Solution
A guided approach device with a latching device and linear displacement mechanism allows for the test head and handling device to be aligned and connected over a predetermined distance, simplifying the process by enabling single-person operation and allowing for maintenance without releasing the latching engagement, using a cylindrical pin socket and catch pin system with a conical insertion bushing for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual alignment and precise positioning by two operators is used for docking test heads and handling devices, then reliable connection is achieved, but the operation becomes laborious and inefficient
Solution Approach 1:
The docking system performs self-alignment through the conical insertion bushing that guides the cylindrical locking pin automatically during the docking process. The system uses its own structural features (conical bushing, cylindrical pin, latching mechanism) to achieve precise alignment without external assistance, enabling single-person operation while maintaining reliable connection
Solution Approach 2:
The conical insertion bushing acts as an intermediary element between the locking pin and the latching device. It facilitates automatic alignment by guiding the cylindrical pin into the correct position, eliminating the need for manual alignment operations while ensuring reliable docking
2Manufacturing precision
If manual alignment by two operators is required, then precise positioning is achieved, but time consumption increases
Solution Approach 1:
The system achieves self-positioning through the conical insertion bushing that automatically guides the locking pin into precise alignment during docking. This self-alignment mechanism eliminates manual positioning operations, achieving both high positioning precision and improved docking efficiency through single-person operation
Solution Approach 2:
The conical insertion bushing is pre-configured with a specific geometry that predetermined the alignment path of the locking pin. This preliminary structural arrangement ensures that when docking occurs, the pin automatically follows the conical guide to achieve precise positioning without requiring manual intervention
3Stability of the object's composition
If the test head is heavily weighted (up to 1000 kg), then structural stability is improved, but alignment and linear positioning become more difficult
Solution Approach 1:
The heavy test head utilizes its own weight to enhance stability while the conical insertion bushing provides automatic alignment guidance. The system design allows the massive component to self-align through the conical guide during docking, eliminating the need for multiple operators to manually position the heavy equipment
Solution Approach 2:
The conical insertion bushing creates a guiding force that counteracts the difficulty of aligning heavy components. The conical geometry provides a mechanical guide that directs the locking pin along a predetermined path, effectively counterbalancing the alignment challenges posed by the test head's significant weight

AI summary
A guided approach device for guiding together a first device (handler or tester) and a second device (including a test head for electronic components), including a latching device with a cylindrical pin socket for holding and fixing a front end of a catch pin. The latching device is connected to a linear displacement device such that the cylindrical pin socket may be displaced in a linear direction at least a short distance corresponding to a multiple of a length of a leading section of the catch pin, which may be inserted into the pin socket. Additionally or alternatively, the latching device is connected to a linear displacement device such that the latching element, a spring element and the pin socket may be displaced, with the catch pin engaged, in a linear direction by the linear displacement device, so that the first and second devices maybe moved relative to one another.
