[0023] This setting starts the first motor 12, so that the first motor 12 drives the first bevel gear 121 to rotate, so that the first bevel gear 121 drives the second bevel gear 122 to rotate, so that the second bevel gear 122 drives the rotating cylinder 123 to rotate on the side wall of the output end of the electric push rod 11, so that the rotating cylinder 123 drives the stirring blade 124 located inside the electrophoresis tank body 2 to rotate, and then uses the stirring blade 124 to stir the electrophoresis liquid to prevent the electrophoresis liquid at the bottom of the electrophoresis tank body 2 from solidifying.

[0024] The side walls of the tray 15 are evenly fixedly connected to the limit blocks 151, and the limit blocks 151 are slidably connected to the inner walls of the through holes opened in the side walls of the basket 16. When the second motor 131 drives the tray 15 to rotate through the rotating sleeve 14, the limit blocks 151 are used to limit the position to prevent the tray 15 and the basket 16 from rotating relative to each other.

[0025] A connecting frame 3 is fixedly connected to the upper end of the base 1, and the upper end of the connecting frame 3 is fixedly connected to the electrophoresis tank body 2, and the first motor 12 and the electric push rod 11 are both located inside the connecting frame 3, which is used to support the electrophoresis tank body 2 using the connecting frame 3 to increase the stability of the electrophoresis tank body 2.

At this time, the parts are directly placed on the tray 15, and then the electric push rod 11 is used to move the tray 15 The electric push rod 11 moves downward, thereby driving the components on the surface of the tray 15 to move downward, so that the components are immersed in the electrophoretic liquid, avoiding the phenomenon of splashing the electrophoretic liquid caused by directly putting the components into the electrophoretic liquid. After the components are electrophoretically treated, the electric push rod 11 is used again to drive the tray 15 to move upward so that the tray 15 is higher than the top of the electrophoretic liquid. At this time, the second motor 131 is used to drive the tray 15 to rotate. As the tray 15 rotates, the components on the tray 15 are subjected to centrifugal force and gradually slide to the edge until they are blocked by the basket 16. As the rotation speed of the tray 15 increases, the electrophoretic liquid on the surface of the components will also be thrown out.
