Embodiment 1

[0023] combine Figure 1-2 , The device in this embodiment includes a pump 1, a steel wire 2 and a power supply 4, and the steel wire 2 is connected to the negative pole of the power supply 4. Turn on the power to pass the current. The current passes through the ring-shaped nickel anode 5 and evenly reaches the cathode steel wire. At the same time, the anode nickel dissolves to form nickel ions that enter the electrolyte. The nickel ions in the electrolyte are reduced on the cathode surface of the steel wire to form an electroplated nickel layer, and at the same time, the diamond micropowder in the droplet is fixed on the steel wire, which is the process of pre-plating. The steel wire with diamond micropowder fixed on the surface enters the electroplating tank again for electroplating. There is no diamond micropowder in the electroplating bath of this electroplating tank, and only the nickel layer can be electroplated. The nickel layer around the diamond micropowder fixed o...

Embodiment 2

[0026] If you want to prepare diamond wire with thicker diamond thickness, there are two ways to get it: First, you can increase the diamond concentration in the pre-plating solution. Although this method is simple, it is impossible to increase the diamond concentration due to the limited diameter of the nozzle. The amplitude increases, which can exacerbate the possibility of nozzle clogging. In this case, the method of combined electroplating with dual nozzles can be used. As in the above embodiment, the diamond micropowder, nickel salt and boric acid of the same quality are weighed, and deionized water of the same quality is added to prepare a pre-plating solution. Heat the pre-plating solution to 45 o C, and add ultrasonic vibration. Connect the two nozzles into the pre-plating solution container respectively, start the two peristaltic pumps and wait for the two nozzles to enter a stable state respectively. Pass the two nickel ring anodes through the steel wire, and conn...

Abstract

The invention relates to a method for continuously producing diamond wires. The method comprises two processes of diamond pre-plating and electroplating and thickening of a nickel layer, wherein a pre-plating device is a mixture coating of thin nickel and diamond on the surface of steel wire by using a liquid droplet formed by the diamond and nickel electroplating solution ejected from a nozzle, and the electroplating and thickening of the nickel layer is to thicken the nickel layer to further wrap the diamond and increase the adhesion of the diamond. The two electroplating processes are connected, and diamond wire with uniform coating for diamond wire saw can be continuously produced. Equipment produced by the method is simple, and the operation is simple and convenient. The required electrolyte quality is less, and the remaining nickel-containing waste liquid is less, the production cost of diamond wire is reduced and the environment is maintained well.

Description

technical field [0001] The invention relates to a continuous production method and device for preparing diamond wires for cutting sapphire crystal rods by using an electroplating method, belonging to the field of diamond wire manufacturing. Background technique [0002] Sapphire single crystal is an oxide composed of aluminum and oxygen. It has great hardness and excellent optical transmittance. It has been applied to the screens of personal consumer electronics products, such as mobile phones, I pads and other electronic devices. At the same time, it is an extremely important substrate material in the microelectronics and optoelectronics industries, and can be used as a substrate material for LED lights. With the growth of demand for personal consumer electronics and the need to save energy, the demand for sapphire crystal chips is increasing. Sapphire crystal wafers are cut from crystal rods by diamond wire saws, and the demand for diamond wires is also on the rise. [...
