Specifically, the gas tube 15 may be connected to a gas source, a check valve that only allows gas to flow from the gas source to the airbag 16 may be disposed between the gas source and the airbag 16, and a discharge tube may be disposed on the gas tube 15 between the check valve and the airbag 16, and a needle valve may be disposed on the discharge tube. The aim of accurately adjusting the position of the liquid level of the electrolyte in the electroplating bath 1 is achieved by emptying the discharge pipe and accurately controlling the quantity of the inclined discharge gas through the needle valve.
As a specific implementation manner of the airbag 16, the airbag 16 is fixed at the bottom of the electroplating bath 1, and the airbag 16 covers the whole bottom surface of the electroplating bath 1;
the connection relationship between the air bag 16 and the electroplating bath 1 is a detachable connection relationship. By adopting the scheme, the mounting frame 2 and the mounting part 3 are arranged on the upper side of the air bag 16, namely, the air bag 16 has little influence on the available space in the electroplating bath 1; the connection relationship between the air bag 16 and the electroplating bath 1 is a detachable connection relationship, and the purpose is to remove the air bag 16 from the electroplating bath when the type of the electroplating bath needs to be changed, and the electroplating bath replacement can be quickly and conveniently completed by only cleaning the electroplating bath 1 and then replacing a new air bag 16, and meanwhile, the removed air bag 16 is convenient to clean outside the electrolyte so as to be convenient to reuse. Preferably, the mounting frame 2 is detachably connected to the plating tank 1. As a person skilled in the art, the above detachable connection relationship can adopt bolt connection, clamping connection and the like.
The foregoing is a more detailed description of the present invention in connection with specific preferred embodiments thereof, and it is not intended that the specific embodiments of the present invention be limited to these descriptions. For those skilled in the art to which the invention pertains, other embodiments that do not depart from the gist of the invention are intended to be within the scope of the invention.
