Problems solved by technology
Existing electroplating hangers for thin pieces may have complex structures, inconvenient loading and unloading of workpieces, or difficulties in conducting electricity, heavy weight of the hangers, or existence of electroplating dead zones, or may cause or aggravate uneven distribution of current or / and flow field
These reduce the coating quality and production efficiency to a certain extent

The invention relates to a hanging fixture for electroplating plane lamina pieces, which comprises a hanging plate (1), a square-ring electricity-conducting frame (2), a square-ring magnetic-conductive cathode compressing frame (7), a square-ring elastic sealing gasket (5), a magnet positioning groove (9) and a magnet (10), wherein the obverse side of the hanging plate (1) is provided with a square groove (3), the square-ring electricity-conducting frame (2) is provided with an electricity-conducting column (11), the square-ring magnetic-conductive cathode compressing frame (7) is externally coated with an electrical insulating material (8), the magnet positioning groove (9) is arranged on the reverse side of the hanging plate (1), and the magnet (10) is put in the magnet positioning groove (9) and externally coated with the electrical insulating material (8). When the hanging fixture is used for fixing a workpiece, the square-ring electricity-conducting frame (2) is put in the middle part of the inside of the square groove (3), and the electricity-conducting column (11) is hermetically embedded in the hanging plate (1) firstly; then, the workpiece (13) is put right above the square-ring electricity-conducting frame (2), the square-ring elastic sealing gasket (5) is attached to the obverse side of the hanging plate (1), and the square-ring magnetic-conductive cathode compressing frame (7) is placed right above the square-ring elastic sealing gasket (5); and finally, the magnet (10) is put in the magnet positioning groove (9). The hanging fixture disclosed by the invention is convenient for workpiece loading and unloading, and simple in structure, and has a small influence on the distribution of flow fields and electric fields.
Description
Technical field [0001] The invention relates to a hanger, in particular to a hanger for electroplating flat sheet pieces, and belongs to the field of electroplating equipment. Background technique [0002] In the electroplating industry, the hanger is an electroplating auxiliary equipment, which plays the role of conducting, supporting and fixing the workpiece. Electroplating on thin pieces has low strength and poor rigidity, and in order to make the electroplating layer meet certain requirements, the method of cathode movement or violent bath agitation is often used in the electroplating process, which makes the thin pieces easy to be in the electroplating process. Deformation, folding, or falling off occurs. Therefore, it is very difficult to effectively install and fix the sheet type workpiece. The existing thin piece electroplating hangers have complex structure, inconvenient loading and unloading of workpieces, difficulty in conducting electricity, heavy hangers, or electr...
