Splicing Device for Tape Feeders with Pressing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The splicing process in tape feeders for electronic component mounting is cumbersome and prone to accuracy issues due to manual operation, which can lead to positional deviations and weakened adhesive strength from operator contact with the splice tape.
Innovation Solution
A splicing device with a tape connecting unit featuring a stationary and movable pressing member that clamps the splice tape from both directions, minimizing operator contact with the adhesive surface and ensuring accurate alignment, along with an elastic member for automatic return and a positioning unit for precise positioning of tape ends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual splicing work is performed by an operator, then the splicing work can be completed, but the adhesive strength may be weakened due to operator contact with the splice tape
Solution Approach 1:
The patent introduces a splicing device as an intermediary tool between the operator and the splice tape. The device includes a holding base with a holding portion that securely holds the splice tape, and a pressing member that applies pressure to join the tapes. This intermediary mechanism eliminates direct operator contact with the adhesive surface of the splice tape, preventing contamination from sweat or dirt while maintaining ease of operation through manual actuation of the pressing member.
2Ease of operation
If splicing work is performed manually, then the work can be completed, but splicing accuracy depends on operator skill proficiency
Solution Approach 1:
The splicing device incorporates a positioning portion that automatically positions the splice tape and tapes to be spliced in the correct alignment. The holding base and positioning structures guide the operator's placement, eliminating the need for high skill proficiency. The device performs the positioning function itself, ensuring consistent splicing accuracy regardless of operator skill level while maintaining simple manual operation.
3Ease of operation
If tape holding bases are rotated multiple times for splicing, then the splicing work can be completed, but positional deviation may occur between tapes
Solution Approach 1:
Instead of rotating the tape holding bases multiple times as in conventional devices, this patent inverts the approach by using a stationary holding base with a positioning portion that guides the splice tape and tapes to be spliced into the correct position. The pressing member moves to apply pressure, rather than rotating the bases. This inversion eliminates the accumulation of positional deviations that occur with multiple rotations while maintaining ease of operation through simple pressing action.
4Ease of operation
If a stationary splice tape is used with rotating tape holding bases, then the splicing work can be completed, but splicing accuracy may be degraded
Solution Approach 1:
The patent introduces a positioning portion as an intermediary element between the stationary splice tape and the tapes to be spliced. This positioning portion includes positioning protrusions and positioning grooves that ensure precise alignment. The holding base with its holding portion secures the splice tape in a fixed position, while the positioning structures guide the incoming tapes into correct alignment, eliminating the need for rotation and preventing positional deviations that would degrade splicing accuracy.

AI summary
An object is to provide a splicing device where splicing accuracy is unlikely to be degraded. A splicing device 1 includes a tape connecting unit 2 that has a stationary pressing member 20 and a movable pressing member 21 which can switch between an open position opened to the stationary pressing member 20 and a close position closed to the stationary pressing member 20. By the open position being switched over to the close position, the movable pressing member 21 is closed to the stationary pressing member 20, the movable pressing member 21 is overlapped with the stationary pressing member 20 in a front and rear direction, a splice tape 9 is folded between the movable pressing member 21 and the stationary pressing member 20, a first connecting end portion 804 and a second connecting end portion 814 are clamped by the splice tape 9 from the front and rear direction, and the first connecting end portion 804 and the second connecting end portion 814 are connected to each other.
