Description

Technical Field

[0001] The utility model relates to the technical field of sand dispersant analysis, in particular to a sand detection system for a sand dispersant used for electroplating diamond. Background Art

[0002] A sanding dispersant refers to an auxiliary agent used in the sanding electroplating process of diamond wire to improve the dispersibility of nickel-plated diamond in the plating solution and promote sanding. An ionic sanding dispersant is usually a chemical substance with an ionic group, which forms a charge repulsion force by making the surface of the nickel-plated diamond in the plating solution have the same charge, thereby achieving uniform dispersion of the nickel-plated diamond in the plating solution. During the sanding process, the electroplated diamond wire is connected to the negative pole of the power supply, so an ideal sanding dispersant usually has a cationic group. In addition, the cationic group of the ionic sanding dispersant can also improve the adhesion of the nickel-plated diamond on the surface of the electroplated diamond wire, thereby increasing the production speed of the electroplated diamond wire. Therefore, it is crucial to develop an analytical device or equipment that can effectively evaluate the sanding promotion ability of the ionic sanding dispersant.

[0003] In view of this, it is necessary to propose a new technical solution to solve the above technical problems. Utility Model Content

When the electrophoresis device is powered on, the charged nickel-plated diamond will move toward the electrode with the opposite charge, that is, the nickel-plated diamond mixed with anionic sand dispersants will move toward the positive electrode, and the nickel-plated diamond mixed with cationic sand dispersants will move toward the negative electrode. When the nickel-plated diamond is enriched around the positive electrode or the negative electrode, the laser signal passing through the electrophoresis tank will be weakened, so that the laser signal received by the photoelectric sensor is weakened, and then the electrical signal output by the photoelectric sensor is weakened, and finally the electrical signal data is output through the signal output terminal. The greater the charge of the nickel-plated diamond mixed with the sand dispersant, the better its dispersibility in the plating solution, and the more the electrical signal is weakened, indicating that the sand-loading ability of the ionic sand dispersant is stronger.

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] A sand dispersant detection system for electroplating diamond is used to detect nickel-plated diamond particles mixed with dispersants of different ion types, including an electrophoresis device, a photoelectric signal conversion device and a signal output end. The electrophoresis device is composed of an electrophoresis tank, a positive electrode, a negative electrode and a power supply. The positive electrode and the negative electrode are arranged at two nozzles of the electrophoresis tank. The power supply is connected to the positive electrode and the negative electrode. The nickel-plated diamond particles mixed with dispersants of different ion types are installed in the electrophoresis tank and move toward the positive electrode or the negative electrode after the power supply is powered on. The photoelectric signal conversion device is composed of a first laser light source, a second laser light source, a first photoelectric sensor and a second photoelectric sensor. The light source and the second laser light source are arranged on one side of the electrophoretic tank, and the first photoelectric sensor and the second photoelectric sensor are arranged on the other side of the electrophoretic tank. The first photoelectric sensor receives the laser signal of the first laser light source and converts the laser signal into an electrical signal. The positive electrode is located on the laser path between the first laser light source and the first photoelectric sensor. The second photoelectric sensor receives the laser signal of the second laser light source and converts the laser signal into an electrical signal. The negative electrode is located on the laser path between the second laser light source and the second photoelectric sensor.

[0028] When the sand loading detection system of the utility model is enriched around the positive electrode or the negative electrode by nickel-plated diamond, the laser signal passing through the electrophoresis tank will be weakened, so that the laser signal received by the photoelectric sensor is weakened and then the electrical signal output by the photoelectric sensor is weakened; the greater the charge amount of the nickel-plated diamond mixed with the sand loading dispersant, the better its dispersibility in the plating solution, the more the electrical signal is weakened, which means that the sand loading ability of the ionic sand loading dispersant is stronger.

[0029] Example

[0030] See also Figure 1 and Figure 2 The utility model provides a sand-loading detection system for a sand-loading dispersant for electroplating diamond, which is used to detect nickel-plated diamond particles mixed with dispersants of different ion types, and then judge the sand-loading ability of the ion type dispersant. The sand-loading detection system for a sand-loading dispersant for electroplating diamond includes an electrophoresis device 1, a photoelectric signal conversion device and a signal output terminal 2.

[0031] More specifically, see Figures 1 to 3 The electrophoresis device 1 is composed of an electrophoresis tank 11, a positive electrode 12, a negative electrode 13 and a power supply, wherein the electrophoresis tank 11 is a square electrophoresis tank, and the material of the electrophoresis tank 11 is quartz. The positive electrode 12 and the negative electrode 13 are graphite electrodes or platinum electrodes, the shape of the positive electrode 12 is sheet-like or rod-like, and the shape of the negative electrode 13 is sheet-like or rod-like. The power supply is preferably a DC power supply, and the voltage adjustment range of the power supply is 60 to 300V. The positive electrode 12 and the negative electrode 13 are arranged at two nozzles of the electrophoresis tank 11, and the power supply is connected to the positive electrode 12 and the negative electrode 13. Nickel-plated diamond particles mixed with dispersants of different ion types are installed in the electrophoresis tank 11, and move toward the positive electrode 12 or the negative electrode 13 after the power supply is powered on.

[0032] More specifically, see Figure 1 and Figure 2 The photoelectric signal conversion device is composed of a first laser light source 3, a second laser light source 4, a first photoelectric sensor 5 and a second photoelectric sensor 6. The first laser light source 3 and the second laser light source 4 are arranged on one side of the electrophoresis tank 11, and the first photoelectric sensor 5 and the second photoelectric sensor 6 are arranged on the other side of the electrophoresis tank 11. The first photoelectric sensor 5 receives the laser signal of the first laser light source 3 and converts the laser signal into an electrical signal. The positive electrode 12 is located on the laser path 7 between the first laser light source 3 and the first photoelectric sensor 5. The second photoelectric sensor 6 receives the laser signal of the second laser light source 4 and converts the laser signal into an electrical signal. The negative electrode 13 is located on the laser path 8 between the second laser light source 4 and the second photoelectric sensor 6. The signal output terminal 2 is connected to the first photoelectric sensor 5 and the second photoelectric sensor 6 and outputs the signal by the electrical signal.

[0033] Preferably, the laser path 7 of the first laser light source 3 passes through 0.5 to 3 cm below the positive electrode 12, and the laser path 8 of the second laser light source 4 passes through 0.5 to 3 cm below the negative electrode 13. More preferably, the laser path 7 of the first laser light source 3 passes through 1 to 2 cm below the positive electrode 12, and the laser path 8 of the second laser light source 4 passes through 1 to 2 cm below the negative electrode 13. Preferably, the laser wavelength range of the first laser light source 3 and the second laser light source 4 is 193 nm to 1064 nm.

[0034] In the implementation of this embodiment, please refer to Figure 1 , Figure 2 and Figure 4, add nickel-plated diamond mixed with cationic dispersant to the electrophoresis tank 11, and turn on the first laser light source 3, the second laser light source 4, the first photoelectric sensor 5 and the second photoelectric sensor 6. Since the nickel-plated diamond mixed with ionic dispersant will settle to the bottom of the square electrophoresis tank 11 under the action of gravity, there are fewer nickel-plated diamond particles near the positive electrode 12 and the negative electrode 13 when the laser path 7 and the laser path 8 pass through, the laser intensity received by the first photoelectric sensor 5 and the second photoelectric sensor 6 is larger, and the electrical signals of the first photoelectric sensor 5 and the second photoelectric sensor 6 are stronger. When the electrophoresis tank 11 is powered on, the nickel-plated diamond with positive charge on the surface moves toward the negative electrode 13 under the action of the electric field. When there are more nickel-plated diamond particles near the negative electrode 13, there are more nickel-plated diamond particles near the negative electrode 13 where the laser path 8 passes, the laser intensity received by the second photoelectric sensor 6 becomes smaller, and the electrical signal output by the second photoelectric sensor 6 decreases. The more the electrical signal output by the second photoelectric sensor 6 is weakened, the stronger the sand-loading ability of the ionic sand-loading dispersant is.

[0035] In another implementation of this embodiment, see Figure 1 , Figure 2 and Figure 4 , add nickel-plated diamond mixed with anionic dispersant to the electrophoresis tank 11, and turn on the first laser light source 3, the second laser light source 4, the first photoelectric sensor 5 and the second photoelectric sensor 6. Since the nickel-plated diamond mixed with ionic dispersant will settle to the bottom of the square electrophoresis tank 11 under the action of gravity, there are fewer nickel-plated diamond particles near the positive electrode 12 and the negative electrode 13 when the laser path 7 and the laser path 8 pass through, the laser intensity received by the first photoelectric sensor 5 and the second photoelectric sensor 6 is larger, and the electrical signals of the first photoelectric sensor 5 and the second photoelectric sensor 6 are stronger. When the electrophoresis tank 11 is powered on, the nickel-plated diamond with negative charge on the surface moves toward the positive electrode 12 under the action of the electric field. When there are more nickel-plated diamond particles near the positive electrode 12, there are more nickel-plated diamond particles near the positive electrode 12 where the laser path 7 passes, the laser intensity received by the first photoelectric sensor 5 becomes smaller, and the electrical signal output by the first photoelectric sensor 5 decreases. The more the electrical signal output by the first photoelectric sensor 5 is weakened, the stronger the sand-loading ability of the ionic sand-loading dispersant is.
