Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Work machines face inefficiencies in picking up components when they are situated in positions where other components interfere, leading to improper pickup and reduced efficiency.
Innovation Solution
A work machine and pickup position selection method that selects one pickup position from multiple options based on positional information and recognition results to minimize interference, using a control device to control a pickup member to avoid overlapping components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single pickup position is selected for a component, then the pickup process is simple and efficient, but the component may be interfered with by overlapping components leading to improper pickup
Solution Approach 1:
The invention divides the pickup position selection into multiple candidate positions (first, second, third pickup positions) around the target component. By segmenting the pickup approach into multiple directional options, the system can select the optimal position that avoids interference from overlapping components, thereby improving pickup reliability without requiring complex overall system redesign.
Solution Approach 2:
The invention performs preliminary detection of the component's orientation and position before pickup. The detection device determines the component's state in advance, and the control device pre-calculates the appropriate pickup position based on this information. This preliminary action allows the system to proactively avoid interference from overlapping components before the pickup attempt begins.
2Reliability
If multiple pickup positions are considered to avoid interference, then pickup reliability improves, but the selection process becomes more complex and time-consuming
Solution Approach 1:
The invention segments the pickup positions into distinct categories (first, second, third pickup positions) with different spatial relationships to the target component. This segmentation allows the control device to efficiently evaluate multiple positions by comparing them against the detected component orientation, rather than performing complex continuous optimization, thus reducing selection time while maintaining reliability.
Solution Approach 2:
The invention changes the parameter of pickup position selection from a continuous variable to a discrete set of predefined positions relative to the component's orientation. By defining pickup positions based on angular parameters (e.g., different sides of the component), the system can quickly select an appropriate position based on the component's detected orientation without exhaustive search.
3Productivity
If the pickup member attempts to pick up a component in an interfered position, then the pickup process is simple, but the component cannot be properly picked up resulting in reduced efficiency
Solution Approach 1:
The invention performs preliminary detection of component orientation and interference conditions before the pickup operation. The detection device identifies the component's state and the control device determines the appropriate pickup position in advance. This preliminary action prevents failed pickup attempts by ensuring the selected position avoids interference from overlapping components, thereby maintaining high productivity.
Solution Approach 2:
The invention uses feedback from the detection device about component orientation and position to dynamically select the pickup position. The control device receives information about the component's state and adjusts the pickup position selection accordingly. This feedback mechanism allows the system to adapt to different component arrangements while maintaining simple pickup operations with high efficiency.

AI summary
A work machine includes a pickup member configured to pick up a component; a storage device configured to store positional information on multiple pickup positions where the pickup member can pick up the component; a recognition device configured to optically recognize a multiple of the component including the pickup target; and a control device configured to select, from the multiple pickup positions of the pickup target component, one pickup position which is less likely to interfere with other components based on the positional information and a recognition result from the recognition device, and cause the pick member to pick up the pickup target component at the one selected pickup position.
