Component Mounting Machine Y-Axis Deviation Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting machines fail to address positional deviations in the feeding direction of components towards multiple suction nozzles, leading to improper pickup.
Innovation Solution
The component mounting machine employs a system to detect and correct Y-axis direction positional deviations of suction nozzles, adjusting the tape feeding mechanism to ensure accurate component pickup by collectively transmitting correction values to the feeders, allowing simultaneous suction operations even with positional deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the component mounting machine uses a transfer head with multiple suction nozzles to simultaneously pick up components from multiple tape feeders, then the productivity is improved, but the reliability deteriorates when positional deviation occurs in the feeding direction of components
Solution Approach 1:
The system performs preliminary detection of positional deviations of suction nozzles in the feeding direction before the actual component pickup operation. The control device stores detection results of positional deviations of the suction nozzles in the feeding direction, and uses these stored values to correct the tape feeding amount in advance, ensuring accurate component pickup even when deviations occur.
Solution Approach 2:
The system implements feedback by detecting the actual positional deviation of suction nozzles from their ideal positions, storing these deviation values, and using them to adjust the tape feeding mechanism. This closed-loop approach ensures that the tape feeding amount is corrected based on actual deviation data, maintaining reliable pickup accuracy while preserving high productivity through simultaneous multi-component pickup.
2Manufacturing precision
If the tape feeding mechanism is adjusted to correct positional deviation, then the manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
The system uses the detection device to automatically measure and detect the positional deviation of suction nozzles, and the control device automatically stores and applies these deviation values to correct the tape feeding amount. This self-service approach allows the system to compensate for positional deviations autonomously without requiring complex external intervention or manual adjustment mechanisms.
Solution Approach 2:
Instead of using complex mechanical adjustment mechanisms to physically reposition suction nozzles, the system substitutes a control-based approach where detection devices measure positional deviations and the control device calculates corrected tape feeding amounts. This replaces mechanical correction with computational correction, reducing mechanical complexity while maintaining or improving precision.

AI summary
A component mounting machine includes a head having at least one set of multiple pickup members arranged so as to be liftable and lowerable, a moving device for moving the head, at least one feeder, and a control device. The feeder is configured to receive correction values for the number of sets of the multiple pickup members, set a target feeding amount for the number of sets based on the received correction values for the number of sets, and sequentially feed components for the number of sets in a predetermined direction with each set target feeding amount. The control device is configured to acquire a positional deviation amount of the multiple pickup members in the predetermined direction for each set, and transmit the correction values for the number of sets based on the acquired positional deviation amount for the number of sets to the feeder so that the feeder collectively receives the correction values for the number of sets at a predetermined timing.
