Tape Position Switching Mechanism for Component Supply Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surface mounting machines face challenges in stably supplying components due to excessive load on component supply tapes, which can lead to instability and inefficiency in component delivery.
Innovation Solution
A component supply device with a tape position switching mechanism that moves the component supply tape vertically without applying additional load, using a movable tape supporter to switch the tape's position from a supporting to a non-supporting state, allowing the tape to move downward by its own weight, thereby stabilizing the component supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the movable bracket rotates to move the carrier tape from the upper tape path to the lower tape path, then the position of the carrier tape is switched, but the carrier tape is partially twisted and excessive load is given to the carrier tape
Solution Approach 1:
The patent introduces a guide block as an intermediary element that the carrier tape passes through during position switching. The guide block is positioned at a specific location in the introducing region to guide the tape from the upper tape path to the lower tape path without rotation, preventing twisting and excessive load while maintaining reliable component supply.
2Productivity
If the carrier tape is moved by rotating the movable bracket, then the tape path is switched, but the tape moves while being partially twisted causing excessive load
Solution Approach 1:
The patent creates an equipotential transition path by positioning the guide block such that the carrier tape moves horizontally through it at the same vertical level, eliminating the need for the tape to climb or descend during switching. This prevents twisting and excessive load while maintaining efficient path switching.

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 solution ensures stable component supply without applying excessive load to the tape, reducing trouble occurrence and enhancing the operation rate of the surface mounting machine.
Implementation Method 1
The tape supporter releases the support of the component supply tape to move the component supply tape downward by being moved from the supporting position to the non-supporting position

AI summary
A component supply device comprises: a main body including a tape path which guides a component supply tape being sent in a longitudinal direction to a component supply position, and an introducing region which communicates with the tape path on a side opposite to the supply position in the longitudinal direction and introduces the supply tape into the tape path; and a tape position switching mechanism which switches the position of the supply tape in a vertical direction with respect to the tape path on the side opposite to the supply position. The tape position switching mechanism includes a supporter movable between a supporting position for supporting the supply tape from below and a non-supporting position separated from the supporting position in a width direction of the supply tape. The supporter releases the supply tape to move the supply tape downward from the supporting position to the non-supporting position.
