Description

Technical Field

[0001] This invention relates to the field of electrolytic processing equipment technology, and particularly to an electrolyte replacement mechanism and an electrolytic processing device. Background Technology

[0002] Electrolytic machining is a method of processing workpieces by utilizing the principle of electrochemical anodic dissolution of metals in an electrolyte. Different electrolytic machining devices are used to perform different electrolytic machining operations.

[0003] Common electrolytic processing equipment includes electrolytic forming equipment, electrolytic deburring equipment, electrolytic grinding equipment, and electrolytic polishing equipment. Among them, electrolytic polishing equipment is mainly used to polish the surface of workpieces to improve the smoothness and brightness of the workpiece surface. Its working principle is to utilize the microscopic dissolution characteristics of the anode surface during electrolysis to preferentially dissolve the microscopic protrusions on the workpiece surface, thereby achieving the effect of smoothing and polishing. It is often used for the surface treatment of decorative parts, optical components, electronic components, etc., such as polishing mobile phone shells and jewelry.

[0004] In the prior art, such as the Chinese authorized patent for a stainless steel electrolytic polishing device (application number: 202323556511.5), a stainless steel electrolytic polishing device is disclosed. This device involves installing a barrier barrel at the middle of the bottom surface of the inner wall of the electrolytic cell, with the rotating shaft and stirring blades positioned inside the barrier barrel. Ideally, the outer wall of the barrier barrel has multiple water-permeable holes. This allows the first motor to be started and the rotating shaft to begin rotating after the stainless steel is placed in the electrolytic cell. This increases the flow rate of the electrolyte in the electrolytic cell while preventing the stirring rod from directly contacting the stainless steel, thus preventing scratches on the stainless steel surface and improving the quality of electrolytic polishing. However, during electrolytic polishing, the anode metal dissolves, and some metal may form tiny particles due to uneven flux density and electrolyte composition. These particles can then undergo localized reduction reactions, regenerating metal that adheres to the cathode surface or deposits and blocks the process. It is difficult for operators to detect excessive metal particles in the electrolyte in time, leading to electrolyte replacement and blockage of the electrolyte pathways, affecting the electrolytic polishing effect and the normal operation of the device. Summary of the Invention

[0022] This invention proposes an electrolyte replacement mechanism and an electrolytic processing device. By setting up an electrolyte replacement mechanism, the electrolytic processing device can detect the metal particle content in the electrolyte in a timely manner and send a signal to remind the staff to replace the electrolyte in time, thereby improving the electrolytic polishing efficiency of the device and ensuring the normal operation of the device. Example

[0023] In this embodiment, the structure of the electrolytic machining apparatus is as follows: Figure 1 , Figure 2 and Figure 5 As shown, where Figure 5Only a portion of the electrolytic processing apparatus is shown, primarily focusing on the parts relevant to this invention. The electrolytic processing apparatus of this invention includes an electrolyte replacement mechanism and a polishing body 19. An outlet 20 and a support frame 21 are fixedly installed at the bottom end of the polishing body 19. A lifting and separating mechanism is provided at the bottom end of the inner wall of the polishing body 19. A rotation auxiliary mechanism is provided at the top end of the support frame 21. The rotation auxiliary mechanism includes a second motor 22 located at the top end of the support frame 21. The second motor 22 is connected to an external power source via a wire. A stirring mechanism 23 is fixedly installed at the output end of the second motor 22. During electrolytic polishing operations, the second motor 22 can drive the electrolyte inside the polishing body 19 to rotate spirally via the stirring mechanism 23, thereby increasing the electrolyte flow rate and improving the efficiency of the electrolytic polishing operation. The lifting and separating mechanism includes a lifting base 24 located at the bottom end of the inner wall of the polishing body 19. A lifting rod 25 is fixedly installed at the top end of the lifting base 24. The top of the lifting rod 25 passes through the support frame 21 and extends to the top of the support frame 21. A connecting plate 26 is fixedly installed on the top of the lifting rod 25. A lead screw 27 is threaded on the inner wall of the other end of the connecting plate 26. A third motor 28 is provided at the bottom of the lead screw 27. The rotating plate 29 is connected to an external power source through a wire. After the workpiece is polished, the third motor 28 can be started, causing the third motor 28 to drive the lead screw 27 to rotate. This causes the lead screw 27 to lift the lifting base 24 through the connecting plate 26 and the lifting rod 25. While lifting the workpiece, the electrolyte adhering to the workpiece can be separated from the workpiece through the through hole opened on the lifting base 24. Compared with the prior art, in this embodiment, the lead screw 27 of the lifting and separation component is set outside the polishing body 19, thereby avoiding the lead screw 27 from contacting the electrolyte and preventing the accelerated corrosion of the thread line on the surface of the lead screw 27. Figures 1 to 5 As shown, an electrolyte replacement mechanism includes: Collection component: used to collect metal particles floating in the electrolyte, including a placement frame 1, which is uniformly installed on the inner wall of the polishing body 19, and a collection filter 2 is fixedly installed on the inner side of the placement frame 1, and a rotating shaft 3 is fixedly installed on the inner wall of the placement frame 1. Judgment component: Used to measure the metal particles collected by the acquisition component and calculate whether the electrolyte needs to be replaced. It includes a gravity sensor set at the bottom of the placement frame 1. Before the electrolytic processing device is running, the gravity sensor records the weight of the placement frame 1 and the acquisition filter 2 as m1. After each acquisition component completes one acquisition, the gravity sensor records the weight of the placement frame 1 and the acquisition filter 2 again and records the weight of the placement frame 1 and the acquisition filter 2 as m2. It also calculates the weight of the metal particles M = m1 - m2 and determines whether M exceeds a preset threshold. If it does, the gravity sensor will send a signal to remind the staff to replace the electrolyte. Rotating component: Used to drive the acquisition component to open for acquisition operations, or to drive the acquisition component to close for measurement and judgment. This includes a rotating cover 4 located at the top of the acquisition filter 2. The top of the rotating cover 4 has evenly spaced rotating grooves 5. A round rod is slidably mounted on the inner wall of each rotating groove 5. These round rods are fixedly mounted on the top of the placement frame 1 away from the rotating shaft 3. This design allows the rotating cover 4 to rotate during acquisition operations, causing the rotating grooves 5 to rotate. The rotating grooves 5 then move the cylinders along their inner walls, thereby causing the cylinders to move the acquisition filter 2 and the placement frame 1. The collection filter 2 and the placement frame 1 are tilted at a certain angle to the inner wall of the polishing body 19. This design increases the amount of electrolyte passing through the collection filter 2, thereby improving the collection efficiency of the collection filter 2 in capturing metal particles in the electrolyte and thus improving the accuracy of the judgment result of the judgment component. It is worth mentioning that the inward spiral direction of the tilt of the collection filter 2 and the placement frame 1 is consistent with the rotation direction of the stirring mechanism 23. This can reduce the turbulence of the electrolyte when it passes through the collection filter 2 and avoid large disturbances in the electrolyte, which would cause uneven distribution of the attached metal particles and thus affect the collection efficiency of the collection component. Drive assembly: Used to provide power to the rotating assembly, thereby driving the rotating assembly to operate. It includes a drive gear block 6 located on one side of the rotating cover 4. A drive gear 7 is meshed on one side of the drive gear block 6. A connecting rod 8 is fixedly mounted on the top of the drive gear 7. A first motor 9 is located on the top of the connecting rod 8. The first motor 9 is connected to an external power source via wires. When the rotating assembly needs to operate, the first motor 9 can be started, causing the first motor 9 to drive the rotating assembly through the connecting rod 8, the drive gear 7, and the drive gear block 6. Further, such as... Figure 2 , Figure 4 and Figure 5As shown, in this embodiment, the drive assembly uses the first motor 9 as a power source to drive the rotating assembly. In other embodiments, the connecting rod 8 can be connected to the second motor 22 by setting a synchronous gear or synchronous belt. After the lifting and separating assembly lifts the lifting base 24 and the workpiece, the second motor 22 drives the stirring mechanism 23 to rotate in the opposite direction. At the same time, the rotating assembly is driven to operate through the connecting rod 8, the drive gear 7, and the drive gear block 6. In order to improve the stability and reliability of the device, a central shaft 13 is provided inside the drive gear 7. Fixed seats 14 are fixedly installed on both sides of the central shaft 13. A rotating abutment block 15 is rotatably installed on the end of the fixed seat 14 away from the central shaft 13. A fixed abutment block 16 is abutted on the end of the rotating abutment block 15 away from the fixed seat 14. The fixed abutment blocks 16 are all fixedly installed on the inner wall of the drive gear 7. One end of the rotating abutment block 15 is set as an inclined surface that fits against one side of the fixed abutment block 16. A fixed block 17 is fixedly installed on one side of the fixed seat 14. Both 15 and the fixed block 17 are connected by springs 18. With this design, after the rotating assembly drives the placement frame 1 to rotate to a certain angle, the connecting rod 8 continues to drive the central shaft 13 to rotate. The central shaft 13 drives the fixed seat 14 to rotate, and the fixed seat 14 drives one end of the rotating abutment block 15 to rotate. At this time, the other end of the rotating abutment block 15 abuts against the fixed abutment block 16. Since the rotating cover 4 cannot continue to rotate, the fixed abutment block 16 drives the rotating abutment block 15 to rotate towards the end away from the fixed abutment block 16. The axis rotates, causing the rotating abutment block 15 to pull the spring 18 to undergo elastic deformation and accumulate elastic potential energy. When the rotating abutment block 15 moves to the side of the fixed abutment block 16, the spring 18 releases the elastic potential energy and undergoes elastic deformation to drive the rotating abutment block 15 to reset, thus avoiding motion interference and preventing load damage to the second motor 22. The first motor 9, the second motor 22 and the third motor 28 are all mature existing technologies, so their internal structures will not be described in detail, and all of them are model LW100.

[0024] In summary, existing technologies suffer from several drawbacks during electrolytic polishing. During this process, the anode metal dissolves, and some metal particles may form micro-particles due to uneven flux density or electrolyte composition. These particles can then undergo localized reduction reactions, regenerating metal that adheres to the cathode surface or deposits and blocks the process. Furthermore, it is difficult for operators to detect excessive metal particles in the electrolyte in a timely manner, leading to electrolyte blockage and impacting the electrolytic polishing effect and the normal operation of the equipment. The electrolytic processing device employing the electrolyte replacement mechanism described in this embodiment can complete the polishing of the workpiece within the electrolytic processing device and separate it through lifting. After the mechanism lifts the workpiece, the first motor 9 is started, causing the connecting rod 8 to rotate. The connecting rod 8 rotates the central shaft 13, which in turn rotates the fixed seat 14. The fixed seat 14 then rotates the rotating abutment block 15, causing the inclined surface at one end of the rotating abutment block 15 to abut against one side of the fixed abutment block 16. This causes the rotating abutment block 15 to rotate the fixed abutment block 16, which in turn rotates the drive gear 7. The drive gear 7, through the drive gear block 6 and the rotating cover 4, rotates the rotating groove 5, causing the rotating groove 5 to move the cylinder along its inner side. The cylinder then moves the placement frame 1 and the collection filter 2. The device forms an inclined angle with the inner side of the polishing body 19 to begin collecting metal particles from the electrolyte. After a preset time (set based on factors such as electrolyte capacity, cross-sectional size, and height of the polishing body 19), the first motor 9 starts in reverse, resetting the rotating and collecting components. At this time, the weight sensor begins measuring the weight m2 of the placement frame 1 and the collecting filter 2, calculating M and making a judgment. This allows for precise monitoring of the metal particle content in the electrolyte, reminding operators to replace the electrolyte promptly. This improves the electropolishing efficiency of the device and ensures its normal operation. (Optional) Furthermore, a valve controllable by a gravity sensor can be installed on the inner wall of the outlet 20. When the gravity sensor detects that the content of metal particles in the electrolyte is too high, it can directly send a signal and control the valve to open, automatically discharging the electrolyte and further improving the working efficiency of the electrolyte replacement mechanism. Due to the installation of the rotating cover 4, the cross-sectional diameter of the lifting base 24 is smaller than the cross-sectional diameter of the inner wall of the polishing body 19. Therefore, a fence is installed at the top of the lifting base 24 to prevent the workpiece from easily moving to the bottom of the rotating cover 4 during the lifting process of the lifting base 24, which would make it difficult to remove the workpiece and affect efficiency.

[0025] Furthermore, in this embodiment, as Figure 2 and Figure 3As shown, a baffle plate 10 is slidably installed on one side of the collection filter 2. The top of the baffle plate 10 is fixedly installed on the bottom of the rotating cover 4. This design allows the rotating cover 4 to rotate and drive the placement frame 1 to reset, causing the baffle plate 10 to rotate to one side of the collection filter 2 and block the flowing electrolyte. This prevents the flowing electrolyte from impacting the placement frame 1 and the collection filter 2, thus extending the time for the gravity sensor to measure the gravity of the placement frame 1 and the collection filter 2, thereby reducing work efficiency. In addition, When polishing workpieces in an electrolytic machining device, the baffle plate 10 can be used to separate the workpieces from the placement frame 1 and the collection filter 2, preventing the workpieces from colliding with the placement frame 1 and the collection filter 2 and causing damage to the collection filter 2. A straight groove 11 is provided on one side of the rotating groove 5, and the straight groove 11 is opened at the top of the rotating cover 4. This allows the cylinder to slide inside the baffle plate 10 when the placement frame 1 is reset and the rotating cover 4 continues to rotate to move the rotating cover 4, thus avoiding the problem of the top of the rotating cover 4 causing movement interference to the cylinder.

[0026] Furthermore, in this embodiment, as Figure 2 and Figure 3 As shown, one of the round rods is longer than the other round rods, and one side of the longer round rod abuts against an arc plate. The arc plate is fixedly installed at one end of the straight groove 11 that the longer round rod abuts against. With this design, when installing the rotating cover 4, the positioning and installation of the rotating cover 4 can be quickly completed by abutting the arc with the longer round rod.

[0027] Furthermore, in this embodiment, the bottom end of the baffle plate 10 is provided with an inclined portion. The inclined surface of the inclined portion at the bottom end of the baffle plate 10 is located on the side close to the placement frame 1, and the other side of the bottom end of the baffle plate 10 is provided as a straight portion. With this design, before the electrolytic processing device is operated, when the baffle plate 10 is located on one side of the placement frame 1 and the collection filter 2, the electrolyte can bypass the baffle plate 10 and soak the collection filter 2 through the bottom end 12 of the baffle plate 10. This ensures that both m1 and m2 contain the weight of the electrolyte attached to the collection filter 2, thereby improving the authenticity and accuracy of the M calculation result. Example

[0028] To further improve the working efficiency of the electrolyte replacement mechanism, in this embodiment, as follows: Figure 2 , Figure 6 and Figure 7As shown, a rotating plate 29 is fixedly installed on one side of the bottom end of the rotating shaft 3. A guide groove 30 is fixedly installed on the side of the rotating plate 29 away from the rotating shaft 3. A drive rod 31 is slidably installed on the inner side of the guide groove 30. An auxiliary inclined plate 32 is fixedly installed on the side of the drive rod 31 away from the guide groove 30. The top of the auxiliary inclined plate 32 is connected to the inner wall of the polishing body 19 through a rotating connecting shaft 33. This design allows the placement frame 1 and the collection filter 2 to rotate when the rotating component drives them to rotate. The placement frame 1 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the rotating plate 29 to rotate. The movable plate 29 drives the guide groove 30 to rotate, and the guide groove 30 drives the drive rod 31 to move along the inner wall of the guide groove 30. At this time, the drive rod 31 moves away from the inner wall of the polishing body 19. The drive rod 31 drives the bottom end of the auxiliary inclined plate 32 to move, so that the auxiliary inclined plate 32 rotates around the rotating connecting shaft 33 as the axis, forming a circle of inclined surface at the bottom end of the inner wall of the polishing body 19, thereby changing the direction of water flow, accelerating the water flow speed, and thus improving the collection effect of the collection component, further improving the accuracy of the judgment result of the judgment component, and improving the working effect of the electrolyte replacement mechanism.
