Component Mounting Device Suction Position Offset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing component mounting apparatuses struggle to accurately pick up components from accommodation sections due to positional deviations caused by inertia and the influence of characters or markings on the component surface, leading to decreased mounting accuracy.
Innovation Solution
The apparatus sets the suction position by calculating an offset based on the difference between the accommodation section and component dimensions, ensuring the nozzle can stabilize the component pickup by aligning with the component's shifted position after inertia, using a control device to adjust the suction nozzles' position dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the accommodation section accommodates the component loosely, then the component can be easily inserted, but the component moves within the accommodation section due to inertia when the tape is stopped, causing positional deviation
Solution Approach 1:
The suction nozzle is positioned in advance at a location offset from the center of the accommodation section toward the movement direction. This preliminary positioning compensates for the component's inertial movement, allowing the nozzle to accurately suction the component even after it shifts when the tape stops.
2Device complexity
If the component mounting apparatus uses standard suction positioning, then the device complexity is low, but the apparatus cannot accurately detect the upper surface of the component due to printed characters or markings, resulting in failed component detection
Solution Approach 1:
Instead of attempting to detect the entire component surface which may have interfering markings, the system focuses detection and suction on a specific local area - the edge region of the component. This localized approach avoids the interference of printed characters while maintaining accurate component detection and positioning.
3Device complexity
If the suction nozzle targets the center position of the component, then the positioning system is simple, but the component cannot be stably picked up when the component moves due to inertia, decreasing mounting accuracy
Solution Approach 1:
The system applies a counteracting offset to the suction nozzle position in advance, positioning it toward the direction of expected component movement. This preliminary anti-action compensates for inertial displacement, ensuring the nozzle remains aligned with the component's actual position after movement and achieves stable pickup.
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
This approach enhances the accuracy of component mounting by stabilizing the suction process, preventing posture instability and ensuring successful component pickup, thereby improving overall mounting precision.
Implementation Method 1
a component supply device that supplies components by feeding a tape, on which a plurality of accommodation sections for accommodating the components are formed, is detachably attached and which sucks the components with a nozzle

AI summary
A component mounting apparatus sets a position that is offset with respect to a suction reference position Rp of a component P (the center position of a cavity 17) toward the front side in a feeding direction (a rearward direction in a Y-direction) as a suction position Sp based on a difference between a dimension of the recess-shaped cavity 17 in the Y-direction and a dimension of the component P accommodated in the cavity 17 in the Y-direction and sucks the component P (Fig. (c)). Therefore, even if the component P in the cavity 17 positionally deviates toward the front side in the feeding direction due to inertia when a carrier tape 16 is stopped, a suction nozzle sucks an appropriate position of the component P.
