Board Work Machine Lead Separation Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing board work machine does not effectively handle the supply of lead components separated from a taped carrier tape, often resulting in the carrier tape being attached to the lead component, which obstructs insertion and can damage gripping claws during the mounting process.
Innovation Solution
A board work machine equipped with a cutting device to separate lead components from carrier tapes and a detection system to identify when the cutting device fails to properly separate the lead components, preventing further damage and ensuring accurate insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a cutting device is used to separate lead components from carrier tapes, then the lead component can be separated from the carrier tape, but the lead is sometimes not cut properly and the lead component may be supplied with the carrier tape still attached
Solution Approach 1:
The patent applies preliminary action by performing detection of the cutting result immediately after the cutting operation. The detection device checks whether the lead component is properly separated from the carrier tape before the component is supplied to the mounting position. This allows for early identification of cutting failures and prevents defective components from proceeding to subsequent operations.
Solution Approach 2:
The patent implements feedback by using the detection device to monitor the cutting operation results and providing this information back to the control system. When incomplete separation is detected, the system can trigger appropriate responses such as stopping the supply of lead components or alerting operators, thereby creating a closed-loop control system that improves separation reliability.
2Productivity
If the lead component is supplied with the carrier tape attached thereto, then the insertion process proceeds, but the carrier tape becomes an obstacle to the insertion and the gripping claws may be damaged
Solution Approach 1:
The detection device performs preliminary checking of the lead component separation status before the component reaches the insertion position. By detecting incomplete separation in advance, the system can prevent defective components from being gripped by the gripping claws, thereby avoiding potential damage while maintaining continuous operation of properly separated components.
Solution Approach 2:
The detection device acts as an intermediary between the cutting device and the supply mechanism. It monitors the separation quality and provides feedback that enables the control system to intervene when necessary, preventing the carrier tape from reaching the gripping claws and causing damage, thus protecting the gripping claws without stopping the entire production line.

AI summary
A component mounter includes a cutting device that cuts a lead of a taped component in which a radial lead component is taped on a carrier tape to separate the radial lead component from the carrier tape, and a bad lead cut detection sensor that detects that the cutting device has failed to separate the radial lead component from the carrier tape.
