Automatic Backup Pin Arrangement for Component Mounting Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity in creating production jobs for component mounting machines arises from the need to arrange backup pins at specific positions for each machine, which differ due to varying component mounting positions across machines. This results in complicated creation work and the inability to arrange backup pins at positions not common to multiple machines.
Innovation Solution
An automatic backup pin arrangement system that uses a common arrangement of backup pins designated in the production job for multiple component mounting machines. The system employs an XY-robot for both component mounting and backup pin arrangement, and a control device determines whether designated backup pin positions are feasible. If not, the control device excludes those positions and automatically arranges backup pins only at designated common positions.

Engineering Contradiction Analysis
1Reliability
If backup pins are arranged at positions specific to each component mounting machine, then the circuit board can be properly supported at component mounting positions, but the creation work of production jobs becomes complicated
Solution Approach 1:
The patent segments the backup pin arrangement into two parts: common positions shared by all machines and machine-specific positions. The control device automatically determines which pins to arrange based on the specific machine's component mounting positions, dividing the complex task into manageable segments that can be handled independently.
Solution Approach 2:
The component mounting machine performs the backup pin arrangement operation itself using its own XY-robot, eliminating the need for external systems. The control device automatically determines the arrangement positions based on the production job and machine-specific parameters, making the system self-sufficient and reducing operational complexity.
2Device complexity
If a common backup pin arrangement is used for multiple component mounting machines, then production job creation is simplified, but backup pins cannot be arranged at positions not common to all machines
Solution Approach 1:
The system dynamically adjusts the backup pin arrangement based on the specific machine's characteristics and the production job requirements. The control device determines which backup pins to arrange at which positions by considering both the common arrangement template and machine-specific component mounting positions, allowing flexible adaptation without manual reconfiguration.
Solution Approach 2:
The patent creates a universal backup pin arrangement template that can be used across multiple machines, while the control device adds machine-specific adaptations automatically. This universal template serves as a base that works for all machines, and the system automatically modifies it to accommodate machine-specific requirements, combining simplicity with adaptability.
3Measurement precision
If backup pins are manually arranged for each machine configuration, then precise positioning is achieved, but time consumption and operational complexity increase
Solution Approach 1:
The patent replaces manual mechanical arrangement with an automated XY-robot controlled by a control device. The control device calculates the optimal backup pin positions based on the circuit board layout and component mounting positions, then the XY-robot automatically places the pins with high precision, eliminating manual intervention and significantly reducing time consumption.
Solution Approach 2:
The control device uses feedback from the production job parameters and machine-specific component mounting positions to automatically determine the optimal backup pin arrangement. The system continuously adjusts the arrangement based on real-time information about the circuit board and mounting requirements, ensuring precise positioning without manual measurement and adjustment.

AI summary
In component mounting machine (10) configured to automatically arranges backup pins (51) at positions designated in a production job, an arrangement of the backup pins designated in the production job is used in common by multiple component mounting machines arranged along a conveyance path of the circuit board, and a position of each backup pin is designated at a position relative to the circuit board. A control device configured to control an operation of each of the component mounting machines determines whether a backup pins exists at a position where the backup pin cannot be automatically arranged in the arrangement of the backup pins designated in the production job, and when the backup pin exist at a position where the backup pin cannot be automatically arranged, excludes the backup pins at the position from the arrangement of the backup pins designated in the production job not to be automatically arranged, and automatically arranges only the other backup pins at the positions designated in the production job.
