Abstract

Provided in the invention is a pickling device for an axial diode. The pickling device comprises an acid liquor box, a pickling tank, and a pickling basket. First elastic elements are arranged at the upper ends of the two side walls of the pickling tank; hollow units are arranged inside the two side walls; and a first cylinder and a second cylinder are arranged inside the two hollow units. Besides, second elastic elements are arranged at the bottom inside the pickling tank and are fixedly connected with a perforated plate; the pickling basket is carried by the perforated plate; the outsides at the two sides of the pickling basket are connected with the first cylinder the second cylinder; and clamp rings are arranged at the upper edge of the basket. The clamp rings are connected with a demisting unit movably; and the demisting unit is connected with a lifting motor by a motor connecting shaft. According to the technical scheme, with the pickling device, full contact between the diode and the acid liquor can be guaranteed and the pickling quality is improved; and acid mist absorption processing is realized and the working environment is improved.

Description

technical field [0001] The invention belongs to the field of diode manufacturing, in particular to an axial diode pickling device. Background technique [0002] The pickling device in the existing axial diode production process generally includes a pickling plate and a pickling tank. The pickling plate is arranged on the pickling tank. In the washing tank, after treatment, it can be recycled. Because the pickling solution is highly corrosive, in the pickling process, the pickling solution is generally washed directly onto the surface of the diode to clean the diode. This method uses a large amount of acid solution, and the acid solution on the surface of the diode is not evenly contacted. , The pickling quality is low. In addition, a lot of acid mist will be generated in the pickling process, resulting in a poor working environment and affecting the health of the staff. Therefore, it is necessary to develop and design a diode pickling device with less acid consumption, hi...
