This invention provides a method and system for mixing substances inside a magnetically controlled droplet. The method includes: adding a droplet containing the substance to be mixed onto a hydrophobic solid substrate infused with a magnetic fluid, causing the magnetic fluid to rapidly envelop the contacting droplet to form a magnetically responsive liquid shell; controlling the movement of the magnetically responsive liquid shell to drive the movement of the enveloped droplet, thereby accelerating the mixing of the substances inside the droplet. The system includes: a hydrophobic solid substrate and a magnetic fluid spread on the surface of the hydrophobic solid substrate. This invention, by causing the magnetically responsive shell enveloping the droplet to rotate around the droplet, generates shear flow at the two-phase interface, increasing the internal dynamics of the droplet and significantly accelerating the mixing process of the substances inside the droplet.

This utility model relates to the field of transfer tool technology and discloses a turnover cart for electrical circuit boards, including a turnover cart body and multiple placement support frames. Each of the four corners of the top of the turnover cart body is provided with a support column, and the four corners of the multiple placement support frames are correspondingly bolted and fixed to the support columns. This utility model, by providing support columns, facilitates the lifting and adjustment of the placement support frames. The placement support frames can support and store anti-static storage boxes. Both sides of the anti-static storage boxes are provided with shock-absorbing magnetic blocks, which can magnetically engage with the top sides of the placement support frames, facilitating the easy placement and removal of the anti-static storage boxes. The anti-static storage boxes are equipped with shock-absorbing protective plates to protect the circuit boards from shock and static interference. The shock-absorbing protective arms can abut against the plate body, providing good shock absorption and clamping effects. This results in excellent anti-static and shock-absorbing protection for the device, with convenient space adjustment, simple handling, high transfer safety and reliability, and good practicality and adaptability.
