Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auto loading method feeder devices face challenges in starting the peeling process of carrier tapes due to fixed feed speeds, which can lead to failed peeling operations, especially with tapes of weak mechanical rigidity, limiting the types of carrier tapes and components that can be used.
Innovation Solution
The implementation of a feed speed determination section that adjusts the peeling start speed based on the properties of various carrier tapes and stored components, combined with a peeling start determination section and recovery function to ensure successful peeling initiation and automatic recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed feed speed is used at peeling start time, then the device complexity is reduced and operation is simplified, but the peeling success rate decreases and reliability worsens
Solution Approach 1:
The feed speed determination section dynamically adjusts the feed speed at peeling start time based on detected properties of the carrier tape and component characteristics, transitioning from a fixed static speed to a variable dynamic speed that adapts to different tape types and component weights, thereby resolving the contradiction between operational simplicity and peeling reliability
Solution Approach 2:
The system changes the feed speed parameter according to detected properties such as carrier tape thickness, width, and component characteristics, allowing the feed speed to be optimized for each specific configuration rather than using a single fixed value, which improves peeling success rate without significantly increasing system complexity
2Productivity
If a high feed speed is used at peeling start time, then productivity is improved and processing time is reduced, but the peeling operation fails for tapes with weak mechanical rigidity
Solution Approach 1:
The feed speed determination section adjusts the feed speed parameter based on detected properties of the carrier tape and component characteristics, using higher speeds for rigid tapes to maintain productivity while using lower speeds for tapes with weak mechanical rigidity to ensure successful peeling, thus resolving the contradiction between productivity and reliability
Solution Approach 2:
The system incorporates detection of carrier tape properties and component characteristics to provide feedback that informs the feed speed selection, allowing the system to automatically adapt the feed speed to match the mechanical properties of the specific tape being processed, ensuring both high productivity and high peeling success rate across different tape types
3Reliability
If the feed speed is reduced for tapes with weak resilience, then the peeling success rate is improved, but the work efficiency and productivity decrease
Solution Approach 1:
The feed speed determination section optimizes the feed speed parameter for each specific carrier tape and component combination, using the minimum necessary speed to ensure successful peeling initiation rather than uniformly reducing speed for all tapes, thereby maintaining high productivity while ensuring reliability for weak tapes
Solution Approach 2:
The system performs preliminary detection of carrier tape properties and component characteristics before the peeling operation to pre-determine the appropriate feed speed, allowing the system to prepare the optimal speed setting in advance and avoid trial-and-error adjustments that would reduce productivity, thus resolving the contradiction between reliability and work efficiency

AI summary
In the present invention, a feeder device (3) includes a tape feeding mechanism which feeds out, at a feed speed, a carrier tape (8) which is formed from a bottom tape (82) which stores components (89) in corresponding multiple component storage sections (83) and a cover tape (81) which is adhered to the bottom tape and covers the component storage sections, and a tape peeling mechanism (7) which includes a tape peeling blade (73) which proceeds between the bottom tape and the cover tape as the carrier tape is fed out to perform peeling, the feeder device supplying the components from the component storage sections at a component supply position (32), and the feeder device further including a feed speed determination section which determines the feed speed (V) at a peeling start time at which a leading end of the carrier tape comes into contact with the tape peeling blade according to at least one of properties of multiple types of carrier tape (8A, 8B, and 8C) and characteristics of the components which are stored. Accordingly, it is possible to adjust the feed speed at the peeling start time according to the types of the carrier tape, and it is possible to increase the success rate of the peeling start.
