Description

Technical Field

[0001] This invention relates to the field of monitoring technology, specifically to a real-time monitoring system and method for particulate matter in electroplating bath solutions. Background Technology

[0002] Traditional electroplating production control systems have low levels of automation, requiring a large number of operators to monitor the electroplating tanks on-site for timely responses. This situation leads to high labor intensity, and the randomness of human operation makes electroplating process parameters unreliable, failing to guarantee the quality of electroplated products. Furthermore, many electrolytes are toxic, and the electroplating environment is poor, posing significant health risks to operators. Therefore, there is an urgent need to achieve real-time monitoring of the electroplating tank solution to improve production efficiency, production safety, and the quality of electroplated products.

[0003] In existing technologies, when monitoring electroplating bath solutions, it is usually only possible to monitor the liquid level in real time, but not to monitor particulate matter in the solution. The scope of functions is limited and cannot meet the monitoring requirements. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned technical problems and provide a real-time monitoring system and method for particulate matter in electroplating baths, thereby improving the accuracy of detection operations and saving people the time and effort required for long-term on-site monitoring.

[0005] To solve the above-mentioned technical problems, the present invention provides a real-time monitoring system for particulate matter in electroplating tank liquid, including a tank body and an implementation unit fixed to the top of the tank body by a detachable equipment structure. The detachable equipment structure includes a connecting rod and a fixing block fixedly connected to both ends of the connecting rod. A processor for analyzing and processing monitoring information is fixedly connected to the top outer wall of one of the fixing blocks.

[0006] The connecting rod is connected to a housing via a lifting mechanism; a sleeve is fixedly connected to the bottom outer wall of the connecting rod.

[0007] The implementation unit includes a particulate matter detection and analysis unit disposed inside the tank and a liquid online analysis unit disposed inside the sleeve. The particulate matter detection and analysis unit consists of an agitation structure for controlling the uniform mixing of the tank liquid and a sampling and analysis structure for sampling the tank liquid.

[0008] Preferably, the lifting part includes a rack fixedly connected to the outer wall of one side of the housing, a gear rotatably connected to the inner wall of the bottom of the connecting rod, and a guide groove provided on the inner wall of one side of the connecting rod. The outer wall of the gear meshes with the outer wall of the rack, and one side of the housing forms a sliding fit with the inner wall of the guide groove through a slider.

[0009] Preferably, the agitation structure includes a sealed cavity disposed on the inner wall of the box, a motor fixed to the inner wall of the top of the box above the sealed cavity, a threaded column rotatably connected to the inner wall of the top of the sealed cavity, a multi-section shrink column fixedly connected to the bottom end of the threaded column, an impeller fixedly connected to the bottom end of the multi-section shrink column, and a hollow cylinder disposed on the outer circumference of the threaded column, wherein the bottom end of the hollow cylinder and the top end of the impeller are rotatably connected, and the output end of the motor is connected to the top end of the threaded column through a connecting shaft.

[0010] Preferably, the outer circumferential wall of the hollow cylinder is provided with a through groove, and the bottom inner wall of the through groove and the bottom outer wall of the box are fixedly connected to the same folding plate;

[0011] The bottom inner wall of the sealed cavity is provided with a through hole that matches the outer wall of the hollow cylinder.

[0012] Preferably, the sampling and analysis structure includes an analysis component fixed to the inner wall of the top of the box, a sampling chamber disposed on the inner wall of the box, a sealing plate inserted into the sampling chamber, a piston rod fixedly connected to the bottom surface of the sealing plate, a connecting plate fixedly connected to the bottom end of the piston rod, and a bellows fixed to the top surface of the connecting plate by a support block, wherein one end of the connecting plate is fixed to the outer wall of the hollow cylinder near the bottom end, and the top end of the bellows penetrates the sealing plate.

[0013] A limiting mesh plate is fixedly connected to one side of the inner wall of the sampling chamber located above the sealing plate.

[0014] Preferably, the online liquid analysis unit includes a cylinder fixed to the inner wall of the bottom of the sleeve, a float plate sleeved on the outer wall of the cylinder, a detection component fixed to the bottom surface of the float plate, and a semi-circular hole provided on the bottom surface of the sleeve, wherein the outer circumferential wall of the float plate and the inner circumferential wall of the sleeve form a sliding fit.

[0015] Preferably, the inner circumference of the sleeve is provided with multiple identical quantitative reminder structures arranged in a vertically equidistant pattern. Each quantitative reminder structure includes a collision sensor fixed to the inner wall of the sleeve, an I-beam inserted into the inner wall of the sleeve, and an elastic element sleeved on the outer wall of the I-beam. The two ends of the elastic element abut against the opposite side of the sleeve and the I-beam, respectively.

[0016] Preferably, an alarm is provided on one side of one of the fixing blocks.

[0017] A method for real-time monitoring of particulate matter in electroplating bath liquid includes the following steps:

[0018] S1: The implementation unit is mounted on the tank through a detachable equipment structure, so that the sleeve is inserted into the tank liquid, and the height of the tank is adjusted by a lifting structure;

[0019] S2: During the rise and fall of the float as the liquid in the sleeve rises and falls, the detection component monitors the water level, turbidity and density of the liquid in real time.

[0020] S3: When the float moves up and down along the cylinder, it comes into contact with the quantitative reminder structure, and then the motor is started by the processor, so that the stirring structure stirs the tank liquid.

[0021] S4: The stirring structure will simultaneously cause the sampling and analysis structure to sample the tank liquid with evenly distributed particulate matter into the sampling chamber, use the analysis component to analyze the tank liquid, and send the analysis results to the processor.

[0022] The beneficial effects of this invention are:

[0023] 1. This invention, by incorporating an implementation unit, allows the float to rise and fall along the cylinder as the bottom of the sleeve is open, following the rise and fall of the liquid level within the sleeve. This facilitates real-time monitoring of the liquid level, turbidity, and density by the detection components. The analysis components perform detailed analysis of particulate matter in the liquid. Through online real-time monitoring of the liquid, data on the distribution of particulate matter at different liquid levels is obtained, improving the accuracy of detection operations, saving time spent on on-site monitoring, expanding the functional scope of the monitoring system, and meeting on-site monitoring needs.

[0024] 2. The motor drives the impeller to rotate via the threaded column and multiple shrinking columns. The rotation of the threaded column causes the hollow cylinder to move up and down through the threads, which in turn causes the impeller to rotate during the lifting and lowering process. This can stir and mix the plating solution and the particles in the tank, making it easier to sample and analyze. The structure can obtain a plating solution with a uniform distribution of particles and plating solution, avoiding the impact of particles and impurities settling at the bottom of the tank on the accuracy of monitoring data.

[0025] 3. When the hollow cylinder is passively moved downward, the piston column moves synchronously through the connecting plate. The piston column moves the sealing plate downward, creating a negative pressure in the sampling chamber. The liquid, after being stirred by the impeller, is then drawn into the sampling chamber above the sealing plate through the bellows. This allows the analytical component probe in the sampling chamber to analyze the liquid and send the analysis results to the processor for easy understanding.

[0026] 4. This invention features a quantitative reminder structure. When the float rises and falls with the level of the liquid in the tank, it contacts one end of the I-beam and pushes it backward, causing the other end of the I-beam to contact the collision sensor. The collision sensor sends a signal to the processor, which then controls the particulate matter detection and analysis unit to start operating. When the float moves away from the I-beam, it resets under the elastic support of the elastic element, thereby achieving the purpose of detecting particulate matter in the tank liquid at different levels.

[0027] 5. The detachable equipment structure is secured to both sides of the tank by fixing blocks, allowing the implementation unit for monitoring particulate matter impurities inside the tank liquid to be mounted on the tank liquid, making disassembly and assembly convenient; the box is pushed up and down to slide in the guide groove through the meshing of rack and gear, thereby driving the particulate matter detection and analysis unit to move up for collection and cleaning or down into the tank liquid for monitoring, making it easy to use.

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0037] Example 1:

[0038] Reference Figure 1-2 As shown, an embodiment of the electroplating bath particulate matter real-time monitoring system of the present invention includes a tank 1 containing the bath solution and an implementation unit fixed to the top of the tank 1 by a detachable equipment structure for monitoring particulate matter impurities inside the bath solution. The detachable equipment structure includes a connecting rod 4 and fixing blocks 2 fixed to both ends of the connecting rod 4 by bolts. The detachable equipment structure is clamped to both sides of the tank 1 by the fixing blocks 2, so that the implementation unit for monitoring particulate matter impurities inside the bath solution is equipped on the tank 1, which is convenient for disassembly and assembly.

[0039] The detachable equipment structure has a processor 5 for analyzing and processing monitoring information fixed to the top outer wall near one side by bolts, which facilitates the operator to observe the particulate matter in the tank liquid in a timely manner; preferably, the processor 5 can be a computer, microcontroller, etc.

[0040] Furthermore, the interior of the connecting rod 4 is connected to the housing 3 via a lifting part. The lifting part includes a rack 9 fixed to the outer wall of one side of the housing 3 by bolts, a gear 10 rotatably connected to the inner wall of the bottom of the connecting rod 4, and a guide groove opened on the inner wall of one side of the connecting rod 4. The outer wall of the gear 10 meshes with the outer wall of the rack 9, and one side of the housing 3 forms a sliding fit with the inner wall of the guide groove through a slider.

[0041] Preferably, the inner wall of the guide groove is bonded with an anti-slip layer; the box 3 is pushed up and down so that it slides in the guide groove through the meshing transmission of the rack 9 and the gear 10, thereby driving the particulate matter detection and analysis unit to move up for collection and cleaning or down into the tank liquid for monitoring, which is convenient to use.

[0042] Furthermore, a sleeve 7 is fixed to the bottom outer wall of the connecting rod 4 by bolts.

[0043] To achieve real-time monitoring of the bath solution; such as Figure 1-7 As shown, the implementation unit includes a particulate matter detection and analysis unit set inside the box 3 for analyzing and processing particulate matter in the tank liquid, and a liquid online analysis unit set inside the sleeve 7 for analyzing and processing the tank liquid. The particulate matter detection and analysis unit consists of an agitation structure for controlling the uniform mixing of the tank liquid and a sampling and analysis structure for sampling the tank liquid.

[0044] Furthermore, such as Figure 3-5As shown, the agitation structure includes a sealed cavity formed in the inner wall of the tank 3, a motor 14 fixed to the inner wall of the top of the tank 3 above the sealed cavity, a threaded column 13 rotatably connected to the inner wall of the top of the sealed cavity, a multi-section shrink column 21 fixed to the bottom of the threaded column 13 by bolts, an impeller 8 fixed to the bottom of the multi-section shrink column 21 by bolts, and a hollow cylinder 12 threadedly connected to the outer circumference of the threaded column 13. The motor 14 is communicatively connected to the processor 5, and the bottom of the hollow cylinder 12 is rotatably connected to the top of the impeller 8. The output end of the motor 14 is connected to the top of the threaded column 13 through a connecting shaft. The processor 5 controls the motor 14 to start, which in turn drives the impeller 8 to rotate through the threaded column 13 and the multi-section shrink column 21. The rotation of the threaded column 13 causes the hollow cylinder 12 to move up and down through the threads, which in turn causes the impeller 8 to rotate during the lifting and lowering process. This can agitate and mix the tank liquid and the particulate matter in the tank 1, and prevent the particulate matter and impurities from settling at the bottom of the tank 1, which would affect the accuracy of the monitoring data.

[0045] Preferably, the outer circumferential wall of the hollow cylinder 12 is provided with a through groove 22, and the bottom inner wall of the through groove 22 and the bottom outer wall of the box body 3 are welded with the same folding plate 23. Preferably, the folding plate 23 and the through groove 22 form a sliding fit. The bottom inner wall of the sealed cavity is provided with a through hole 24 that matches the outer wall of the hollow cylinder 12. Under the restriction of the through groove 22 and the through hole 24, the hollow cylinder 12 moves up and down in a straight line along the surface of the threaded column 13 driven by the thread. Moreover, due to the folding plate 23, the tank liquid can be prevented from entering the interior of the hollow cylinder 12.

[0046] As a further supplement, such as Figure 3 As shown, the sampling and analysis structure includes an analysis component 15 fixed to the inner wall of the top of the box 3, a sampling chamber 19 opened in the inner wall of the box 3, a sealing plate 17 inserted inside the sampling chamber 19, a piston column 18 fixed to the bottom surface of the sealing plate 17 by bolts, a connecting plate 11 fixed to the bottom end of the piston column 18 by bolts, and a bellows 20 fixed to the top surface of the connecting plate 11 by a support block. One end of the connecting plate 11 is fixed to the outer wall of the hollow cylinder 12 near the bottom end, and the top end of the bellows 20 penetrates the sealing plate 17.

[0047] Preferably, the analysis component 15 includes a particle size analyzer, etc., and is communicatively connected to the processor 5; it is used to analyze parameters such as particle size and count of the collected tank liquid. When the hollow cylinder 12 moves passively downward, the piston column 18 moves synchronously via the connecting plate 11. The piston column 18 moves the sealing plate 17 downward, creating a negative pressure in the sampling chamber 19. The tank liquid, after being stirred by the impeller 8, is then drawn into the sampling chamber 19 above the sealing plate 17 through the bellows 20. This allows the probe of the analysis component 15, located in the sampling chamber 19, to analyze the tank liquid and send the analysis results to the processor 5 for easy understanding.

[0048] Furthermore, a limiting mesh plate 16 is fixedly connected to the inner wall of one side of the sampling chamber 19 located above the sealing plate 17; this does not affect the detection of the liquid introduced into the sampling chamber 19 by the probe of the analysis component 15, while limiting the rising height of the sealing plate 17. After a single round of detection is completed, the processor 5 controls the motor 14 to move upward, which in turn drives the impeller 8 to move upward and reset via the threaded column 13, and then squeezes the collected liquid in the sampling chamber 19 through the piston column 18 and the sealing plate 17, causing it to flow back into the tank 1 through the bottom end of the bellows 20.

[0049] Furthermore, such as Figure 6 As shown, the online liquid analysis unit includes a cylinder fixed to the inner wall of the bottom of the sleeve 7, a float plate 26 sleeved on the outer wall of the cylinder, a detection component 25 fixed to the bottom surface of the float plate 26, and a semi-circular hole opened on the bottom surface of the sleeve 7, and the outer circumferential wall of the float plate 26 and the inner circumferential wall of the sleeve 7 form a sliding fit.

[0050] Preferably, the detection component 25 is communicatively connected to the processor 5. The detection component 25 is one or a combination of several of the following: a liquid level sensor, a turbidity sensor, and a liquid density sensor [not shown in the figure]. The sleeve 7 is inserted into the liquid in the tank 1. Since the bottom of the sleeve 7 is open, the float 26 can move up and down along the cylinder as the liquid level in the sleeve 7 changes. This allows the detection component 25 to conveniently monitor the water level, turbidity, and density of the liquid in real time and send the information to the processor 5 so that people can understand it in a timely manner.

[0051] As a further supplement, such as Figure 6-7 As shown, the inner circumference of the sleeve 7 is provided with multiple identical quantitative reminder structures arranged in a vertical row at equal intervals. The quantitative reminder structure includes a collision sensor 29 fixed to the inner wall of the sleeve 7, an I-beam 27 inserted into the inner wall of the sleeve 7, and an elastic member 28 sleeved on the outer wall of the I-beam 27. The two ends of the elastic member 28 respectively abut against the opposite side of the sleeve 7 and the I-beam 27. The collision sensor 29 is communicatively connected to the processor 5.

[0052] Preferably, the elastic element 28 can be made of an elastic material such as a spring; when the float 26 rises and falls with the height of the liquid in the tank, it will contact one end of the I-beam 27 and push it backward, so that the other end of the I-beam 27 contacts the collision sensor 29. The collision sensor 29 sends a signal to the processor 5 so that it can control the particulate matter detection and analysis unit to start operating. When the float 26 moves away from the I-beam 27, it will reset under the elastic support of the elastic element 28, thereby achieving the purpose of detecting particulate matter in the tank liquid at different liquid levels.

[0053] For the purpose of early warning; such as Figure 1As shown, an alarm 6 is installed on one side of the detachable equipment structure. The alarm 6 is connected to the processor 5. When the particulate matter detection and analysis unit and the liquid online analysis unit detect that the amount of particulate matter in the tank liquid is large or the amount of tank liquid is low, the processor 5 controls the alarm 6 to be activated to remind personnel and save people's energy from monitoring on-site for a long time.

[0054] In this embodiment, the detachable equipment structure is secured to both sides of the tank 1 by fixing blocks 2, thereby equipping the implementation unit for monitoring particulate impurities inside the tank liquid onto the tank 1. Pushing the housing 3 up and down causes it to slide within the guide groove via the meshing transmission of rack 9 and gear 10, thereby driving the particulate matter detection and analysis unit to move upwards for cleaning or downwards into the tank liquid for monitoring.

[0055] During monitoring, the sleeve 7 is inserted into the liquid in the tank 1. Since the bottom of the sleeve 7 is open, the float 26 can move up and down along the cylinder according to the level of the liquid entering the sleeve 7. This allows the detection component 25 to monitor the water level, turbidity, and density of the liquid in real time and send the information to the processor 5 for timely understanding. Moreover, as the float 26 moves up and down with the level of the liquid, it will contact one end of the I-beam 27 and push it backward, so that the other end of the I-beam 27 contacts the collision sensor 29. The collision sensor 29 sends a signal to the processor 5 so that it can control the motor 14 to start operating. When the float 26 moves away from the I-beam 27, it will reset under the elastic support of the elastic element 28, thereby achieving the purpose of detecting particulate matter in the liquid at different levels.

[0056] After the processor 5 starts the motor 14, it drives the impeller 8 to rotate via the threaded column 13 and the multi-section shrink column 21. The rotation of the threaded column 13 causes the hollow cylinder 12 to move up and down through the threads, which in turn causes the impeller 8 to rotate during the lifting and lowering process. This can stir and mix the tank liquid and the particles in the tank 1. When the hollow cylinder 12 moves down passively, the piston column 18 moves synchronously via the connecting plate 11. The piston column 18 drives the sealing plate 17 to move down, creating a negative pressure in the sampling chamber 19. The tank liquid, which has been stirred by the impeller 8, is then drawn into the sampling chamber 19 above the sealing plate 17 through the bellows 20. The analysis component 15 probe in the sampling chamber 19 can then analyze the tank liquid and send the analysis results to the processor 5 for easy understanding. After a single-round detection is completed, the processor 5 controls the motor 14 to move upward, which in turn drives the impeller 8 to move upward and reset via the threaded column 13. The piston column 18 and the sealing plate 17 then squeeze the collection tank liquid in the sampling chamber 19, causing it to flow back into the tank 1 through the bottom end of the bellows 20.

[0057] Example 2:

[0058] A method for real-time monitoring of particulate matter in electroplating bath solution, such as Figure 1-7 As shown, it includes the following steps:

[0059] S1: The implementation unit is mounted on the tank 1 through a detachable equipment structure, so that the sleeve 7 is inserted into the tank liquid, and the height of the tank 3 is adjusted by the lifting structure.

[0060] S2: During the rise and fall of the float 26 as the liquid level in the sleeve 7 changes, the detection component 25 monitors the water level, turbidity and density of the liquid in real time.

[0061] S3: When the float 26 moves up and down along the cylinder, it comes into contact with the quantitative reminder structure, and then the processor 5 controls the motor 14 to start, so that the stirring structure stirs the tank liquid.

[0062] S4: The stirring structure will simultaneously cause the sampling and analysis structure to sample the tank liquid with uniformly distributed particulate matter into the sampling chamber 19, and use the analysis component 15 to analyze the tank liquid and send the analysis results to the processor 5.

[0063] In this embodiment, the detection component 25 monitors the water level, turbidity, and density of the tank liquid in real time. When the tank liquid level changes, the float 26 contacts the quantitative reminder structure, thereby triggering the switch of the motor 14 to agitate the tank liquid. The agitation structure then samples the tank liquid with uniformly distributed particles into the sampling chamber 19 via the sampling and analysis structure. The analysis component 15 analyzes the tank liquid. By monitoring the tank liquid online in real time, the distribution monitoring data of particles in the tank liquid at different liquid levels can be obtained, improving the accuracy of the detection operation and saving people the effort of long-term supervision.

[0064] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
