Environmentally friendly threaded rotary head

Abstract

The invention discloses an environment-friendly screw thread turret head, comprising a casing, wherein the casing is internally provided with a rotating rod, a conductive block and a driving device for driving the rotating rod to rotate. A threaded hole is formed in the conductive block. The conductive block is in threaded fit with the rotating rod via the threaded hole, and the conductive block is electrically connected with an external power source. The rotating rod is rotatably connected with the base in the casing, and one end of the rotating rod is exposed out of the casing. The driving device drives the rotating rod to rotate. The conductive block is in threaded fit with the rotating rod via the threaded hole, rotating the rotating rod to move up and down. The conductive block is always in contact with the rotating rod, and the conductive block can conduct a stable current to the rotating rod to realize conduction, so that the conductive effect of the turret head is stable. The drive device is also capable of providing required form of movement for the rotating rod. Using the thread contact method, changing the former use of mercury, carbon brush contacts, etc., improves the conductivity efficiency, the conductive effect is stable, and performance is more stable.

Description

technical field [0001] The invention relates to the field of electroplating equipment, more specifically, it relates to an environment-friendly threaded rotary head. Background technique [0002] The conductive rotary rod of the conductive rotary head of the electroplating equipment is not in direct contact with the static terminal. Liquid metal (mercury) with good conductivity is used to conduct the current of the static terminal to the conductive rotary rod. The top of the conductive rotary rod is set There is a cavity containing liquid metal, and the static terminal is a cylindrical rod. The cylindrical rod extends into the cavity and does not contact the side wall of the cavity. The liquid metal in the cavity is fully in contact with the end of the cylindrical rod, and the liquid metal It is a conductive medium, but the conduction effect of the conductive rotating rod is unstable. At the same time, liquid metal (mercury) is a harmful substance that is easy to cause harm ...
