Description

Continuous electrochemical processing device

The invention relates to an electrochemical process, in particular to an electrochemical processing device capable of continuously electrochemically processing a workpiece.

In recent years, in addition to the diversification of functions, the development trend of electronic products has also pursued light and thin. Therefore, the size and quality requirements of the components are also increased, and the characteristics of the product materials such as hardness and ductility are gradually diversified. If you simply process with traditional machining technology, it will be difficult to meet the requirements of quality, productivity and cost. At present, electrochemical machining breaks through the limitations of conventional machining in terms of precision, and has become a processing technology with both mass production, low cost and high precision.

Electrochemical machining is a non-traditional processing method used to process extremely hard materials, also known as electrolytic machining, where the metal workpiece is the anode and the electrode is the cathode, and the electrodes do not need to be in contact with the workpiece to have a pitch. The workpiece is removed by electrochemical reaction of the electrolyte between the electrode and the workpiece. Because of the many advantages of electrochemical machining, it meets the special needs of many metal processing. However, the conventional electrochemical processing device is not a continuous process. Before performing electrochemical machining, the workpiece must be mounted on the electrochemical processing device. After the machining is completed, the workpiece is removed, and the next workpiece is attached to the electrochemical processing device. Electrochemical machining is carried out, so that the action of mounting and removing the workpiece is repeated, so the efficiency of the conventional electrochemical processing device is limited.

It is an object of the present invention to provide a continuous electrochemical machining apparatus that continuously electrochemically processes a workpiece.

It is an object of the present invention to provide a continuous electrochemical machining apparatus that can measure a workpiece to know the state of the workpiece after electrochemical machining, and to modify the processing conditions of the electrochemical machining according to the state.

The invention provides a continuous electrochemical processing device comprising an electrode transfer module, an electrode module and a tape conveying mechanism. The electrode module is connected to the electrode transfer module and has an electrode. The tape conveying mechanism is disposed corresponding to the electrode module, and comprises a fixing seat, a moving module and a plurality of clamping units. The moving module is located at the fixing base and moves to the fixing seat, and the clamping units are respectively set In the transition module and the fixed seat.
