Component Mounting Machine Seating Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting machines face challenges in stabilizing the seating of suction nozzles and push-up pots, particularly in the horizontal direction, due to angular deviations and offset deviations, which affect the positioning accuracy of components during mounting and demounting processes.
Innovation Solution
A component mounting machine with a control device that performs a seating improvement process by applying forces in predetermined directions, including horizontal and vertical directions, to stabilize the engagement between the mounting base and the mounting/demounting tool, using a tool moving mechanism and a mounting base moving mechanism to improve the positional relationship before the tool holds a component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the suction nozzle is pressed against the jig base at the lower end after being exchanged, then the seating of the suction nozzle in the up-down direction with respect to the lifting and lowering shaft is improved, but the horizontal seating including angular deviation and offset deviation of the suction nozzle axis cannot be improved
Solution Approach 1:
The patent applies preliminary action by performing a seating improvement process before the suction nozzle performs its picking function. The control device executes this process by moving the mounting base in predetermined directions to stabilize the seating of the suction nozzle on the lifting and lowering shaft, ensuring proper horizontal and vertical alignment before actual component picking begins.
Solution Approach 2:
The patent replaces purely mechanical pressing mechanisms with a control device that orchestrates movement of the mounting base in predetermined directions. This substitution allows for more precise and multi-directional adjustment of the suction nozzle seating, addressing both vertical and horizontal alignment issues that simple mechanical pressing cannot resolve.
2Manufacturing precision
If a push-up pot is pressed against a jig base from the top after an exchange, then the seating in the up-down direction is improved, but the horizontal seating particularly cannot be improved only by applying a downward pressing force
Solution Approach 1:
The patent applies preliminary action by performing a seating improvement process before the push-up pot performs its pushing function. The control device executes this process by moving the mounting base in predetermined directions to stabilize the seating of the push-up pot on the mounting base, ensuring proper horizontal and vertical alignment before actual component pushing begins.
Solution Approach 2:
The patent replaces simple downward mechanical pressing with a control device that orchestrates movement of the mounting base in predetermined directions. This substitution enables multi-directional adjustment including horizontal alignment, making the mounting process more effective while maintaining operational simplicity through automated control.
3Ease of operation
If the suction nozzle is detachably mounted with a clearance provided by an O-ring, then the mounting and demounting process is simplified, but the positioning accuracy and seating stability are reduced due to angular and offset deviations
Solution Approach 1:
The patent applies preliminary action by performing a seating improvement process before the suction nozzle performs its picking function. The control device executes this process by moving the mounting base in predetermined directions to stabilize the seating, eliminating angular and offset deviations caused by the clearance fit, while maintaining the simplicity of detachable mounting with O-ring.
Solution Approach 2:
The patent replaces reliance on precise mechanical clearance fitting with a control device that actively adjusts and stabilizes the seating position. This substitution maintains the ease of detachable mounting while compensating for positioning inaccuracies through controlled movement in predetermined directions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively stabilizes the seating of mounting/demounting tools, reducing positional deviations and improving the accuracy of component placement by ensuring proper alignment and engagement, thus enhancing the overall mounting and demounting process.
Implementation Method 1
In a state in which the suction nozzle is not mounted, the locking ring is positioned at a position in which the gravitational force of the locking ring is balanced with the urging force of the coil spring with respect to the lifting and lowering shaft.
Implementation Method 2
A coil spring and a locking ring are fitted on the outer periphery of the lower end of the lifting and lowering shaft.
Implementation Method 3
a component mounting head for picking up a component by suction

AI summary
In order to stabilize the seating of a detachable tool detachably mounted on a mounting base, the component mounting machine, comprises: a mounting base provided in a component mounting machine main body and movable at least in the horizontal direction; a mounting/demounting tool, detachably mounted on the mounting base and movable in the up-down direction while holding a component; a tool moving mechanism configured to move the mounting/demounting tool in the up-down direction; a mounting base moving mechanism configured to move the mounting base at least in the horizontal direction; and a control device configured to perform a seating improvement process for applying a force in a predetermined direction, including the horizontal direction, to the mounting base on which the mounting/demounting tool is mounted after the mounting/demounting tool is mounted on the mounting base and before the mounting/demounting tool holds the component, by a moving operation different from a moving operation for holding the component on the mounting/demounting tool in the mounting base moving mechanism.
