[0002] Electroplated diamond tools are a type of superhard tool made by electroplating diamond abrasive into a metal (usually nickel or nickel-based alloy) coating. Due to their sharpness and excellent shape retention, electroplated diamond tools are widely used in the grinding and machining of hard and brittle materials. The production process includes substrate fabrication, substrate pretreatment (including electrochemical degreasing, ultrasonic degreasing, and electrolytic degreasing; some materials also require impact nickel plating), electroplating with abrasive coating (including air plating, sand plating, and thickening plating), and post-treatment.

[0003] Traditional production equipment has some shortcomings in the electroplating sand-planting process, such as: the cathode movement during empty plating and thickening plating requires manual operation, resulting in low operation frequency, inconsistent intervals, or even no cathode movement operation throughout the process; the traditional sand-planting tank has holes drilled on the sides and bottom and covered with a layer of gauze to prevent diamond leakage, which has limited water permeability, increases the concentration difference of electroplating solution in different areas, and is not conducive to the formation of a uniform coating on the product surface. Utility Model Content

The annular hanging rail 3 is driven by an external motor and circulates continuously (this is prior art and will not be described in detail here). The plating tank assemblies 2 are arranged sequentially along the running direction of the annular hanging rail 3. A liftable hanging fixture assembly 4 is fixedly installed on the moving end of the annular hanging rail 3. The diamond tools to be electroplated are connected to the hanging fixture assembly 4 and transported by the annular hanging rail 3. When passing the plating tank assembly 2, the hanging fixture assembly 4 descends, allowing the diamond tools to enter the plating tank assembly. Electroplating is performed in component 2. A filter plate 5 is fixed inside the chemical tank 1, which divides the inside of the chemical tank 1 into a recovery chamber 11 and an addition chamber 12. A first circulation pipe 6 is fixedly connected through the side wall of the recovery chamber 11, and a second circulation pipe 7 is fixedly connected through the side wall of the addition chamber 12. Both the first circulation pipe 6 and the second circulation pipe 7 are connected to the inside of the plating tank assembly 2 through branch pipes 8. The old chemical solution is discharged from the plating tank assembly 2 into the first circulation pipe 6, enters the recovery chamber 11, is filtered by the filter plate 5, and then enters the addition chamber 12. The replenished new chemical solution enters from the addition chamber 12 and is diverted to the plating tank assembly 2 through the second circulation pipe 7.

[0021] The plating tank assembly 2 includes an empty plating tank 21, two sand plating tanks 22, an ultrasonic water washing tank 23, and multiple thickened plating tanks 24 arranged sequentially along the running direction of the annular hanging rail 3. Each sand plating tank 22 has a diamond container 25 fixed inside, and the diamond container 25 contains diamonds. Each diamond container 25 has a distribution mechanism 9 fixed inside to prevent diamond precipitation.

[0022] The diamond container 25 is made of porous ceramic material, which has better water permeability and can reduce the difference in drug concentration at different locations.

[0023] The mounting assembly 4 includes a fixed base 41 fixedly connected to the moving end of the annular hanging rail 3. An electric push rod 42 is fixedly connected to the fixed base 41. A lifting platform 43 is fixedly connected to the moving end of the electric push rod 42. A stepper motor 44 is fixedly connected to the bottom of the lifting platform 43. A rotating platform 45 is fixed to the output shaft of the stepper motor 44. Multiple mounting bodies 46 are fixed to the bottom edge of the rotating platform 45. A linkage mechanism 47 is fixed to the center of the bottom surface of the rotating platform 45. The stepper motor 44 is controlled by a PLC to reciprocate, realizing the cathode movement function of the empty plating process and the thickening plating process.

[0024] Multiple guide rods 431 are fixedly connected to the top surface of the lifting platform 43. Each guide rod 431 is slidably connected to the fixed seat 41. Multiple connecting rods 451 are fixedly connected to the side wall of the rotating platform 45. One end of each connecting rod 451 is slidably connected to the side wall of the lifting platform 43, making the lifting and rotation trajectory of the hanging body 46 more stable.

[0025] The distribution mechanism 9 includes a central tube 91 fixedly connected inside the diamond container 25. Multiple perforated blowpipes 92 are fixedly connected through the lower end of the side wall of the central tube 91. A connecting plate 93 is rotatably connected to the upper end of the inner wall of the central tube 91. A threaded rod 94 is fixedly connected to the bottom surface of the connecting plate 93. A piston plate 95 is threadedly connected to the side wall of the threaded rod 94. A guide strip 96 is fixed to the inner wall of the central tube 91. The piston plate 95 is slidably connected to the guide strip 96. When the connecting plate 93 rotates forward and backward, it drives the threaded rod 94 to rotate synchronously, thereby driving the piston plate 95 to rise and fall. The piston plate 95 slides in a sealed manner with the central tube 91, so that the perforated blowpipes 92 can blow and suck from the bottom of the diamond container 25, thereby causing the precipitated diamond to move upward and redistribute.

[0026] The linkage mechanism 47 includes a plug shaft 471 fixedly connected to the center of the bottom surface of the rotating platform 45. The plug shaft 471 is coaxially arranged with the central tube 91. Multiple insert teeth 472 are fixed at the lower end of the side wall of the plug shaft 471. A spline groove 931 is opened on the top of the connecting plate 93. Through the connection between the insert teeth 472 and the spline groove 931, the reciprocating rotation of the stepper motor 44 can drive the connecting plate 93 to rotate.

[0027] A first one-way valve 61 is installed on each of the multiple branch pipes 8 connected to the first circulation pipe 6, and a second one-way valve 71 is installed on each of the multiple branch pipes 8 connected to the second circulation pipe 7. The first one-way valve 61 only allows the agent to enter the first circulation pipe 6 from the plating tank assembly 2, and the second one-way valve 71 only allows the agent to enter the plating tank assembly 2 from the second circulation pipe 7, thereby realizing the recycling of the electroplating agent.

[0028] Both the first circulation pipe 6 and the second circulation pipe 7 are driven by a pump to circulate the medicine. A filling pipe 13 is fixedly connected to the medicine tank 1. One end of the filling pipe 13 is connected to the addition chamber 12, and the other end of the filling pipe 13 is connected to an external medicine container for replenishing the medicine.

[0029] In this utility model, the diamond tool to be electroplated is connected to the hanging body 46 from the upper hanging area of ​​the annular hanging rail 3. Then, the diamond tool reaches the plating tank assembly 2 as the annular hanging rail 3 moves. The electric push rod 42 pushes the lifting platform 43 to descend so that the diamond tool enters the empty plating tank 21. At the same time, the stepper motor 44 drives the rotating platform 45 to rotate back and forth to realize the cathode movement function. After the empty plating is completed, the diamond tool is transported to the sand plating tank 22. When the electric push rod 42 pushes the lifting platform 43 to descend, the insertion shaft 471 at the bottom of the rotating platform 45 enters the central tube 91, and the insertion teeth 472 and spline groove 931 are inserted. The diamond tool then enters the diamond container 25. Traditional sand plating tanks use PP material grooves to hold diamonds, with holes drilled on the sides and bottom and covered with a layer of gauze to prevent diamond leakage. Its water permeability is limited, which increases the concentration difference of electroplating solution in different areas and is not conducive to... A uniform coating is formed on the product surface, and the diamond container 25 is made of porous ceramic material, which has better water permeability and can reduce the concentration difference of the solution in different positions. When the stepper motor 44 reciprocates, it drives the connecting plate 93 to rotate. When the connecting plate 93 rotates forward and backward, it drives the threaded rod 94 to rotate synchronously, thereby driving the piston plate 95 to rise and fall. The piston plate 95 and the central tube 91 slide in a sealed manner, so that the porous blowpipe 92 can blow and suck from the bottom of the diamond container 25, thereby causing the precipitated diamond to move upward and redistribute. After the sand plating is completed, the diamond tools are cleaned in the ultrasonic water washing tank 23 to remove surface sand, making the diamond distribution on the product surface more even and avoiding dead corners during rinsing. After cleaning, the diamond tools are sequentially placed into multiple thickening plating tanks 24 for thickening plating, and finally removed from the hanging area of ​​the annular hanging rail 3. During the electroplating process, the solution is circulated and filtered through the first circulation pipe 6, the second circulation pipe 7 and the filter plate 5, and the additives consumed by the solution are replenished through the filling pipe 13, making the product batch more stable.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
