Solution Overview
Problem
Existing specimen transport systems experience pulsation in thrust, leading to vibration and instability during specimen transport, which can result in specimen scattering and inefficient analysis processing.

1Productivity
If electromagnetic actuators are used to move container carriers on the transport plane, then transport speed and productivity are improved, but pulsation is generated in the thrust and vibration occurs during transport
Solution Approach 1:
A magnetic coupling unit is introduced as an intermediary component between adjacent electromagnet units. This magnetic coupling unit mediates the magnetic field interaction, allowing magnetic flux to pass through and couple the electromagnet units together, thereby reducing thrust pulsation and vibration while maintaining transport speed
Solution Approach 2:
The magnetic coupling unit is pre-installed between adjacent electromagnet units before operation. This preliminary arrangement ensures that the magnetic coupling is already in place to smooth out thrust variations before the transport operation begins, preventing vibration and instability during specimen transport
