This thesis will focus on the improvement of the ＂motion control of Wire
assembly” assembly line in the catheter device for catheter ablation. The operating
characteristic of the device is to reach the heart through the 2.0-3.5cm venous
blood vessel. It is conceivable that the design of the device′s motion mechanism
and internal parts should be compact and subtle, and because medical devices
must comply with specific medical specifications and strict quality requirements
during the manufacturing process, currently most of the industry still relies on
manual assembly. The requirements for eyesight, hand stability and technical
experience are extremely high, and the demand for human resources has also
become higher. In today′s environment of lack of manpower, it is undoubtedly
worse.
This research is to use the principle of the eye mold mechanism in the
automatic threading system of the wire cutting machine to improve the design of
the fixture, supplemented by the TRIZ theory to find out the bad factors and
improvement opportunities of the assembly process of the motion control line
components, and to carry out the operation interface of the assembly line , Process
design improvement, to reduce the work cycle, assembly process and production
resource requirements, and reduce the dependence on the experience and
technology of operators, so that the production management and manufacturing
units are more flexible in the scheduling of operators, and finally achieve both
The goal of reducing resource requirements and improving production capacity
and quality.
In addition to achieving the three goals set for the purpose of the research (1)
III
reducing the 60-second assembly cycle time, (2) reducing the dependence on the
ability of the operator, and (3) integrating the two welding stations into one, the
research results finally allowed demand for laser welding equipment and
operators has been reduced simultaneously. | en_US |
