A panel inspection apparatus with integrated cleaning parts that automatically clean contact pads and pins, utilizing multiple-axis moving portions and recovery systems to maintain cleanliness and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact pads and contact pins are used for inspection, then inspection functionality is achieved, but particles are generated and contact issues occur
Solution Approach 1:
The cleaning part performs preliminary cleaning action on the contact pad before inspection. The cleaning part includes a cleaning component that removes particles from the contact pad surface in advance, preventing particle generation during subsequent contact operations with contact pins
Solution Approach 2:
The system implements self-service cleaning where the cleaning part is integrated into the inspection apparatus and automatically cleans the contact pad without requiring manual intervention. The cleaning part moves along with the panel carrier and performs cleaning actions during the inspection process
2Productivity
If contact pads and contact pins are contacted repeatedly, then inspection operations continue, but contact issues and particle generation increase
Solution Approach 1:
The cleaning part operates continuously alongside the panel carrier during inspection operations. As the panel carrier moves through the inspection line, the cleaning part continuously cleans the contact pad, ensuring ongoing removal of particles and maintenance of contact quality without interrupting inspection productivity
Solution Approach 2:
The system incorporates monitoring that detects contact issues and particle accumulation, providing feedback to trigger cleaning actions. The cleaning part responds to detected conditions by performing cleaning operations to restore optimal contact quality, maintaining reliable inspection operations
3Object-generated harmful factors
If manual cleaning is performed, then particle removal is achieved, but facility utilization decreases and time is lost
Solution Approach 1:
The cleaning part is integrated into the inspection apparatus and performs automatic cleaning without requiring manual intervention. The cleaning part moves with the panel carrier through the inspection line, performing cleaning actions automatically during the inspection process, eliminating time loss associated with manual cleaning operations
Solution Approach 2:
The cleaning operation continues simultaneously with inspection operations rather than requiring separate dedicated cleaning time. The cleaning part operates continuously alongside the panel carrier, removing particles during the inspection process itself rather than requiring stops for manual cleaning
4Object-generated harmful factors
If contact pads are cleaned frequently, then particle accumulation is reduced, but device complexity increases
Solution Approach 1:
The cleaning part is designed as a multi-functional component that integrates cleaning, monitoring, and movement functions. The cleaning part includes a cleaning component, monitoring component, and moving mechanism that work together as an integrated unit, reducing overall system complexity compared to separate dedicated cleaning systems
Solution Approach 2:
The cleaning function is merged with the existing inspection apparatus structure. The cleaning part is integrated into the panel carrier system and moves along with it, combining cleaning operations with the inspection process rather than requiring separate independent cleaning systems

AI summary
A panel inspection apparatus includes an inspection zone including an inlet through which a display panel is input, an outlet through which the display panel is discharged, and an inspection line extending from the inlet to the outlet through which the display panel is moved, a return zone including a return line extending to the inlet of the inspection zone, a panel carrier on which the display panel is seated, moving from the inlet of the inspection zone to the outlet, and returning from the outlet to the inlet through the return line, and a cleaning part located in the return zone and cleaning the panel carrier in the return line.
