Description

A microchannel electrolytic laser composite processing device

Technical Field

The invention relates to the technical field of electrolytic laser composite processing, and in particular to a microchannel electrolytic laser composite processing device.

Background technique

Electrolytic machining is the process of machining workpieces using the principle of electrolytic metal anode dissolution. Compared with other machining methods, it has the advantages of wide machining range, high production efficiency, good machining quality, no tool cathode loss and no macro-cutting force. It has been widely used in blade surface machining, mold cavity machining, special gear machining and other fields. Electrolytic machining technology is also convenient for realizing one-time machining and molding of multiple microchannels, which can greatly improve machining efficiency. When electrolytic machining is used for microstructures, how to achieve high-quality and efficient machining and give full play to the advantages of electrolytic machining is a research content that must be carried out in the engineering application of electrolytic machining technology. The accuracy of electrolytic machining can be improved to a certain extent by sidewall insulation, masking and other methods, but the cathode needs to be processed, and traditional mask electrolytic machining requires a layer of photoresist or masking layer (electrical insulation) to be covered on the surface of the workpiece. This technology has high requirements for equipment. Each workpiece needs to go through the mask making process such as film pasting, exposure, and development, and cannot be reused. In addition, in most cases, due to the static electrolyte during mask machining, the product in the processing area can only be transferred through diffusion, natural convection, etc., resulting in low machining efficiency and easy peeling of the mask layer.

In order to solve the problems of the mask not being reusable and low processing efficiency, laser surface modification technology is introduced into the production of the mask, and then the surface structure is processed by electrolytic processing, that is, electrolytic laser composite processing technology. Electrolytic laser composite processing is a combination of electrolytic processing and laser surface modification technology. Laser modification is performed on the surface of the workpiece material to form a mask layer (modified layer), which protects the material matrix during the electrolytic processing. The metal on the workpiece surface with the mask protection layer dissolves slowly or does not dissolve, while the area without the mask protection layer undergoes rapid electrolytic corrosion.

However, most of the existing laser composite electrolytic processing equipment are special machines, which are only suitable for processing one or several parts and have poor versatility. Among them, laser composite electrolytic processing equipment is divided into laser-promoted electrolysis in the processing area and laser mask-inhibited electrolysis in the non-processing area. Laser-promoted electrolytic processing equipment has the common path of laser and electrolyte, which inevitably leads to the problem of laser power attenuation; and the existing laser mask equipment is relatively bulky. Once installed, the subsequent movement and leveling steps are also cumbersome.
