Automatic tape setting apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic tape setting apparatuses require dedicated tape feeders and pull-out sections for carrier and top tapes, leading to increased costs and complexity, especially when handling various components.
Innovation Solution
An automatic tape setting apparatus with a pitch feed mechanism, top tape peeling and delivery mechanisms, and a tape transport system that uses a general-purpose tape feeder, eliminating the need for dedicated pull-out sections by synchronously controlling the pitch feed and top tape transfer operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If pull-out sections are provided in carrier tape and top tape for gripping by tape mounting arm, then automatic tape setting is achieved, but dedicated tape feeder and transport path are required, increasing device complexity and cost
Solution Approach 1:
The tape feeder is designed with universal functionality to handle both carrier tape and top tape without requiring dedicated pull-out sections. The transport path is configured to accommodate standard tape structures, allowing the same feeder to perform multiple functions (transporting carrier tape and top tape) without modification, thereby reducing device complexity while maintaining automation.
Solution Approach 2:
The pull-out section requirement is extracted and eliminated from the tape structure. Instead of modifying the tape to include pull-out sections for gripping, the invention uses the existing tape edges and standard transport path, removing the need for dedicated gripping sections and simplifying both the tape and feeder design.
2Adaptability or versatility
If pull-out sections are provided for each component type, then various components can be handled, but effort and cost increase due to customization requirements
Solution Approach 1:
The tape feeder is designed with universal functionality to handle both carrier tape and top tape without requiring dedicated pull-out sections. The transport path is configured to accommodate standard tape structures, allowing the same feeder to perform multiple functions (transporting carrier tape and top tape) without modification, thereby reducing device complexity while maintaining automation.
Solution Approach 2:
The invention changes the operational parameters of the tape feeder to achieve versatility without customization. By adjusting the transport path configuration and timing parameters, the same feeder can handle different component types using standard tapes, eliminating the need for physical modifications or dedicated pull-out sections for each component type.
3Reliability
If suction tube is used to hold top tape end portion with air injection, then top tape can be secured to winding reel, but suction and holding error occurs due to injection pressure requirements
Solution Approach 1:
The suction system using air injection and suction tubes is replaced with a mechanical holding mechanism. The top tape end portion is held and secured using mechanical means such as clamps or rollers, eliminating the need for complex pneumatic systems and reducing the risk of holding errors associated with air pressure control.

AI summary
A component package tape is transported to a pitch feed mechanism section by a tape transport device and is held in a first tape holding section by a tape holding releasing device. Furthermore, a top tape adhered to a carrier tape that is transported to the pitch feed mechanism section is peeled from the carrier tape by a top tape peeling section while being clamped at a leading end section, is transferred to a top tape delivery mechanism section, and is held in a second tape holding section by the tape holding releasing device.
