Description

Technical Field

[0001] This application relates to the field of automation of plating solution testing equipment, and in particular to an automatic test film replacement device and its working method and an online plating solution analyzer. Background Technology

[0002] In the process of detecting the components in a plating solution using an online plating solution analyzer, the test film is usually tested directly. At this time, each element in the excited test film will emit secondary X-rays, and the secondary X-rays emitted by different elements have specific energy characteristics or wavelength characteristics. The detection system of the online plating solution analyzer measures the energy and quantity of these emitted secondary X-rays. Then, the instrument software in the online plating solution analyzer can convert the information collected by the detection system into the types and contents of various elements in the sample, thereby determining the types and contents of various elements in the plating solution.

[0003] However, due to the cleanliness of the plating solution, or the accumulation of particulate matter in the solution with the replenishment of new reagents, dirt or suspended sediments will continuously accumulate on the surface of the test membrane, thus affecting the test results. Therefore, online plating solution analyzers require test membrane replacement after a period of continuous operation. Currently, the solution for replacing the test membrane is to first stop the machine and then manually replace the test membrane. This carries the risk of contaminating the test membrane surface due to manual replacement, and the replacement cycle is unpredictable. In production, this could lead to data inaccuracies that are only discovered after a period of time, resulting in poor product quality or product scrap. Summary of the Invention

[0004] The purpose of this application is to provide an automatic test membrane replacement device and its working method, as well as an online plating solution analyzer, which can automatically replace the test membrane, avoid the risk of contamination of the test membrane surface caused by manual replacement, and optimize the accuracy of the test membrane replacement timing.

[0005] This application discloses an automatic test membrane replacement device for replacing test membranes in an online plating bath analyzer. The automatic test membrane replacement device includes a plating bath tank, a test membrane roll, a motor, a solenoid valve, a drain assembly, and a control assembly. The plating bath tank has a hollow interior forming a cavity. The plating bath tank includes a tank body and a main viewing panel. The main viewing panel covers the opening of the tank body and is movably connected to the tank body. The main viewing panel has a transparent window. One side of the tank body is connected to an upper liquid pipe, and the other side of the tank body is connected to an outlet liquid pipe. The test membrane roll includes a first roll end, a second roll end, and a membrane material. One end of the membrane material is connected to the first roll end, and the other end of the membrane material is connected to the second roll end. The membrane material has multiple test membranes evenly spaced on it. The first roll end and the second roll end are both located outside the plating bath tank. At least part of the membrane material between the first roll end and the second roll end is located inside the cavity, and the test membranes on the membrane material located inside the cavity are positioned directly opposite the transparent window.

[0006] The motor controls the first roll end to wind up the film material. The solenoid valve is connected to the first valve in the liquid inlet pipe, and controls the flow of the plating solution in the liquid inlet pipe through the first valve. The drain assembly is connected to the solenoid valve. When the solenoid valve controls the first valve to close, the drain assembly drains the plating solution in the cavity. The control assembly controls the solenoid valve to close the first valve according to a preset time, controls the solenoid valve to make the drain assembly drain the plating solution in the cavity, controls the motor to wind up the first roll end of the film material, so that the film material in the cavity is replaced with a new test film, and controls the solenoid valve to open the first valve.

[0007] Optionally, the automatic test membrane replacement device further includes a moving component, one end of which is connected to the housing and the other end of which is connected to the main viewing panel. The moving component controls the main viewing panel to move away from or towards the housing. When the control component controls the solenoid valve to drain the plating solution from the cavity, the moving component causes the main viewing panel to move away from the housing.

[0008] Optionally, the moving component includes a sensor and four robotic arms, which are arranged diagonally, and the sensor synchronously controls the movement of the four robotic arms.

[0009] Optionally, the plating bath further includes a guide plate disposed within the cavity. The guide plate is made of a transparent material, with one end connected to the side of the bath near the first roll end and the other end connected to the side of the bath near the second roll end. The guide plate has a rectangular channel inside, within which the film material within the cavity is located. The top of the guide plate has an outlet facing the main viewing panel, and the bottom of the guide plate has an inlet facing the main viewing panel. The film material within the channel passes through the outlet and connects to the first roll end, and through the inlet and connects to the second roll end. The side of the guide plate facing the main viewing panel also has multiple perforated holes.

[0010] Optionally, the edge of the main viewing panel is provided with a rubber ring, which is interference-fitted with the opening of the box body, and the rubber ring is provided with clearance grooves on the side near the first roll end and the second roll end, respectively, and the two ends of the film material pass through the clearance grooves and are connected to the first roll end and the second roll end, respectively.

[0011] Optionally, the drainage assembly includes a return pipe connected to the upper liquid pipe, and a second valve is provided on the return pipe, which is connected to the solenoid valve; when the solenoid valve controls the first valve to close, it simultaneously controls the second valve to open; wherein, the height of the upper liquid pipe is lower than the height of the outlet pipe.

[0012] Optionally, the bottom height of the cavity is lower than the bottom height of the main viewing panel, and the height of the connection area between the upper liquid pipe and the box body is located between the bottom height of the cavity and the bottom height of the main viewing panel.

[0013] This application also discloses a method for operating an automatic test membrane replacement device, used in the automatic test membrane replacement device described above, comprising the following steps:

[0014] Set a preset time, which is the replacement time of the test membrane;

[0015] When the preset time is reached, the first valve in the liquid inlet pipe is closed;

[0016] Drain the plating solution from the cavity;

[0017] Control the winding of the first roll of film at the end of the control panel, and replace the test film in the plating bath; and

[0018] Open the first valve to allow the plating solution to enter the cavity.

[0019] Optionally, after emptying the plating solution from the plating tank, the main viewing panel is separated from the tank body; after controlling the first roll end to rewind the film and replacing the test film in the plating tank, the main viewing panel is used to cover the opening of the tank body, sealing the tank body.

[0020] This application also discloses an online plating solution analyzer, which includes an X-ray emitter, an analysis component, and an automatic test film replacement device as described above. The X-ray emitter emits X-rays onto the test film through a window of the automatic test film replacement device, and the analysis component analyzes the particles on the test film.

[0021] Compared to the current method of manually replacing test membranes, this application provides an automatic test membrane replacement device. According to a pre-set replacement time, at preset intervals, the control component sequentially closes the first valve to stop the flow of plating solution into the cavity, then drains the plating solution from the cavity. This prevents plating solution from flowing out when the membrane is subsequently wound up using the first roll end. Furthermore, the control component controls the first roll end to wind up the membrane to the same length each time, ensuring that a new test membrane is always facing the viewing window after each winding, achieving automatic test membrane replacement. After replacing the test membrane, the control component automatically resumes operation of each structure and repeats the test membrane replacement steps at the specified intervals. Since no manual contact with the test membrane is required during replacement, the risk of surface contamination caused by manual replacement is avoided. Moreover, because each structure in the automatic test membrane replacement device operates according to a preset time, there is no time deviation, thus optimizing the accuracy of test membrane replacement timing. This allows for timely test membrane replacement and accurate plating solution detection, which is beneficial for improving product quality. Attached Figure Description

[0032] It should be understood that the terminology, specific structural and functional details used herein are merely for describing particular embodiments and are representative. However, this application may be implemented in many alternative forms and should not be construed as being limited to the embodiments set forth herein.

[0033] Furthermore, unless otherwise explicitly specified and limited, "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] The present application will be further described below with reference to the accompanying drawings and optional embodiments.

[0035] Figure 1 This is a schematic diagram of an online plating solution analyzer, such as... Figure 1 As shown in the figure, this application provides an online plating solution analyzer 10, which includes an X-ray emitter 100, an analysis component 200, and an automatic test film replacement device 300. The automatic test film replacement device 300 can automatically replace the test film 324 at regular intervals. The X-ray emitter 100 emits X-rays to the test film 324 through the window 314 of the automatic test film replacement device 300. The analysis component 200 analyzes the particles on the test film 324 to obtain the types and contents of various elements in the plating solution.

[0036] Using the online plating solution analyzer 10 in this embodiment, the testing personnel only need to observe the analysis results of the test membrane 324. There is no need to manually replace the test membrane 324 or manually control the liquid inlet and outlet operations, which greatly improves the level of automation and achieves the effect of freeing up manpower and saving labor costs.

[0037] Figure 2 This is a schematic diagram of an automatic membrane replacement device for testing, such as... Figure 2 As shown, this application embodiment also provides an automatic test membrane replacement device 300, which can be used as an independent structure or to replace the test membrane of the online plating solution analyzer 10.

[0038] The automatic test membrane replacement device 300 includes a plating solution tank 310, a test membrane roll 320, a motor 330, a solenoid valve 340, a drain assembly 350, and a control assembly 360. The plating solution tank 310 has a hollow interior forming a cavity 313. The plating solution tank 310 includes a housing 311 and a main viewing panel 312. The main viewing panel 312 covers the opening of the housing 311 and is movably connected to the housing 311. When the main viewing panel 312 is closed on the housing 311, the main viewing panel 312 and the housing 311 form a sealed structure. The main viewing panel 312 is provided with a window 314. One side of the housing 311 is connected to the upper liquid pipe 380, and the other side of the housing 311 is connected to the lower liquid pipe 400. The plating solution flows from the upper liquid pipe 380 into the cavity 313 and then flows out from the lower liquid pipe 400.

[0039] Combination Figure 2 and Figure 3As shown, the test film roll 320 adopts a roll-like structure, including a first roll end 321, a second roll end 322, and film 323. One end of the film 323 is connected to the first roll end 321, and the other end of the film 323 is connected to the second roll end 322. The first roll end 321 and the second roll end 322 are roller structures. By rotating one of them, the film 323 is wound up, and the other is pulled to release new film 323. The film material 323 is made of high-transparency polyester material, and has a plurality of test films 324 evenly spaced on it; the first roll end 321 and the second roll end 322 are both located outside the plating bath 310, and the film material 323 between the first roll end 321 and the second roll end 322 is at least partially located inside the cavity 313, and the test films 324 on the film material 323 located inside the cavity 313 are directly opposite the window 314, that is, the length of the film material 323 wound up each time is equal to the distance between two adjacent test films 324 on the film material 323.

[0040] The motor 330 controls the first roll end 321 to wind up the film 323. The solenoid valve 340 is an adjustable angle solenoid valve that can meet various environmental requirements. The solenoid valve 340 is connected to the first valve in the liquid inlet pipe 380, and controls the flow of plating solution in the liquid inlet pipe 380 through the first valve. The drain assembly 350 is connected to the solenoid valve 340. When the solenoid valve 340 controls the first valve to close, the drain assembly 350 drains the plating solution in the cavity 313. The control assembly 360 controls the solenoid valve 340 to close the first valve according to a preset time, controls the solenoid valve 340 to make the drain assembly 350 drain the plating solution in the cavity 313, controls the motor 330 to make the first roll end 321 wind up the film 323, so that the film 323 in the cavity 313 is replaced with a new test film 324, and controls the solenoid valve 340 to open the first valve.

[0041] Compared to the current method of manually replacing the test membrane 324, this application provides an automatic test membrane replacement device 300. According to a preset replacement time, after each preset time interval, the control component 360 will first close the first valve to stop the flow of plating solution into the cavity 313, and then drain the plating solution from the cavity 313. This ensures that the plating solution will not flow out when the membrane material 323 is subsequently wound up with the first roll end 321. Moreover, each time the control component 360 controls the first roll end 321 to wind up the membrane material 323 to the same length, so that after each winding, there will be a new test membrane 324 facing the window 314 on the membrane material 323, thus achieving the purpose of automatically replacing the test membrane 324. After the test membrane 324 is replaced, the control component 360 will automatically resume the operation of each structure and continue to repeat the above steps of replacing the test membrane 324 according to the interval. Since no manual contact with the test membrane 324 is required during the replacement process, the risk of contamination of the test membrane 324 surface caused by manual replacement can be avoided. Moreover, since each structure in the automatic test membrane replacement device 300 works according to the set time, there will be no time deviation. Therefore, the accuracy of the test membrane 324 replacement time is optimized, enabling timely replacement of the test membrane 324 and accurate detection of the plating solution, which is beneficial to improving product quality.

[0042] In this embodiment, the motor 330 and the first roll end 321 are located above the plating bath 310, and the second roll end 322 is located below the plating bath 310. Each time the test membrane 324 is replaced, the membrane 323 is pulled from bottom to top to avoid bringing out the plating solution remaining in the membrane 323 or the bottom of the cavity 313 when pulling the membrane 323 downward. At the same time, it can also ensure that the membrane 323 between the first roll end 321 and the second roll end 322 is always in a stretched and taut state to avoid the problem of the test membrane 324 not being aligned with the window 314.

[0043] In this embodiment, the control component 360 employs a PLC (Programmable Logic Controller). The replacement time of the test membrane 324 can be accurately determined by analyzing the elemental content in the plating solution and calculating the consumption of the test membrane 324, thus accurately predicting the replacement time, i.e., the preset time. After each preset time, the control component 360 controls the solenoid valve 340 to close the first valve, controls the solenoid valve 340 to cause the drainage component 350 to drain the plating solution from the cavity 313, controls the motor 330 to cause the first roll end 321 to wind up the membrane material 323, thereby replacing the membrane material 323 in the cavity 313 with a new test membrane 324, and controls the solenoid valve 340 to open the first valve, repeating this cycle.

[0044] In this embodiment, before replacing the test membrane 324, the main viewing plate 312 needs to be moved to create a gap between the main viewing plate 312 and the housing 311, allowing the membrane material 323 to be pulled out. After the main viewing plate 312 is placed on the housing 311, it compresses the membrane material 323 and forms a sealed cavity 313 with the housing 311, preventing the membrane material 323 from being pulled out. Specifically, the automatic test membrane replacement device 300 also includes a moving component 370. One end of the moving component 370 is connected to the housing 311, and the other end is connected to the main viewing plate 312. The moving component 370 controls the main viewing plate 312 to move away from or towards the housing 311. The moving component 370 can be connected to the control component 360. When the control component 360 controls the solenoid valve 340 to drain the plating solution in the cavity 313, it controls the moving component 370 to move the main viewing panel 312 away from the housing 311.

[0045] Of course, the moving component 370 can also control the main viewing panel 312 to rotate around one side of the housing 311 to achieve opening and closing, without having to remove the entire main viewing panel 312 from the housing 311, thus saving more effort.

[0046] like Figure 4 As shown, in one embodiment of the moving component 370, the moving component 370 includes a sensor 371 and four robotic arms 372. The four robotic arms 372 are respectively arranged at the four corners of the main viewing panel 312, in a diagonal configuration. The sensor 371 synchronously controls the movement of the four robotic arms 372. In this embodiment, the moving component 370 does not need to be connected to the control component 360. The sensor 371 is used to detect the liquid level in the cavity 313. When the sensor 371 detects that the plating solution in the cavity 313 has been drained, it controls the four robotic arms 372 to pull the main viewing panel 312 away from the housing 311, leaving a sufficient gap so that the first roll end 321 can pull the film 323 normally.

[0047] Of course, the robotic arm 372 can also be replaced with a telescopic rod, spring, or other structure, as long as it can extend and retract under the action of the sensor 371, so that the main viewing panel 312 can cover and move away from the opening of the box 311.

[0048] Furthermore, such as Figure 5As shown, a guide plate 315 is also provided inside the plating bath 310. The guide plate 315 is disposed inside the cavity 313 and is made of transparent material. One end of the guide plate 315 is connected to the side of the box 311 near the first coil end 321, and the other end of the guide plate 315 is connected to the side of the box 311 near the second coil end 322. Specifically, the guide plate 315 can be fixed inside the box 311 by welding, bonding or other methods.

[0049] The guide plate 315 has a rectangular channel 319 inside, and the film material 323 in the cavity 313 is located in the channel 319. The top of the guide plate 315 has an outlet 316 facing the main viewing plate 312, and the bottom of the guide plate 315 has an inlet 317 facing the main viewing plate 312. The film material 323 in the channel 319 passes through the outlet 316 and is connected to the first roll end 321. The film material 323 in the channel 319 passes through the inlet 317 and is connected to the second roll end 322. Each time the control motor 330 rotates the first roll end 321, it pulls the film 323 to move within the channel 319. With the addition of the guide plate 315, the film 323 will not deviate during its movement within the guide plate 315. Moreover, during the process of introducing plating solution into the cavity 313 or draining the plating solution from the cavity 313, the plating solution is prevented from directly impacting the film 323, thus avoiding problems such as rotation or loosening of the film 323, which would prevent the test film 324 from being aligned with the window 314.

[0050] Furthermore, to prevent the test membrane 324 from failing to accurately detect the particulate components in the plating solution, multiple perforated holes 318 are provided on the side of the guide plate 315 facing the main viewing plate 312. This reduces the impact area of ​​the film material 323 on the plating solution, allowing the plating solution to enter the guide plate 315, fully contact the test membrane 324, and exchange with the plating solution flowing outside the guide plate 315 in a timely manner. Of course, depending on the actual situation, the holes 318 can also be made on other surfaces of the guide plate 315.

[0051] Furthermore, such as Figure 6As shown, to prevent leakage in the plating bath tank 310, this embodiment of the application also provides a rubber ring 500 on the edge of the main viewing panel 312. The rubber ring 500 is interference-fitted with the opening of the housing 311. When the main viewing panel 312 is closed on the housing 311, the inner wall of the opening of the housing 311 squeezes the rubber ring 500 to prevent plating solution leakage. Moreover, to prevent the rubber ring 500 from excessively squeezing the film material 323 during the process of closing the main viewing panel 312, causing the film material 323 to deform or even break, this embodiment of the application also provides a clearance groove 510 in the area of ​​the rubber ring 500 corresponding to the film material 323, so that both ends of the film material 323 pass through the clearance groove 510 respectively. Specifically, the rubber ring 500 is provided with clearance groove 510 on the side near the first roll end 321 and the second roll end 322 respectively, and both ends of the film material 323 pass through the clearance groove 510 and connect to the first roll end 321 and the second roll end 322 respectively.

[0052] In the embodiments of this application, such as Figure 7 As shown, the drain assembly 350 is a return pipe 390, which is connected to the inlet pipe 380. A second valve is provided on the return pipe 390, and this second valve is connected to the solenoid valve 340. When the solenoid valve 340 controls the first valve to close, it simultaneously controls the second valve to open; conversely, when the solenoid valve 340 controls the first valve to open, it simultaneously controls the second valve to close. With this design, no additional control structure for the drain assembly 350 is needed. The inlet and outlet liquids are directly controlled by a single solenoid valve 340, further optimizing the product structure. Alternatively, the drain assembly 350 can be made into a pipe connected to the bottom of the housing 311, allowing direct draining when the pipe is opened. Or, the drain assembly 350 can be a combination of a water pump and a pipe, allowing the water pump to actively extract the plating solution from the cavity 313.

[0053] The height of the upper liquid pipe 380 is lower than the height of the outlet liquid pipe 400, and the height of the return liquid pipe 390 is also lower than the height of the outlet liquid pipe 400. When the second valve is opened, the plating solution in the outlet liquid pipe 400 and the cavity 313 can be discharged directly through the return liquid pipe 390 without the need for a water pump.

[0054] Furthermore, the bottom height of the cavity 313 is lower than the bottom height of the main viewing panel 312, and the height of the connection area between the liquid inlet pipe 380 and the housing 311 is between the bottom height of the cavity 313 and the bottom height of the main viewing panel 312. When the main viewing panel 312 is opened to replace the test membrane 324, the residual plating solution will fall to the bottom of the cavity 313 because the bottom of the cavity 313 is lower, and will not flow out from the opening of the housing 311.

[0055] Correspondingly, such as Figure 8 As shown, this application embodiment also provides a method for operating an automatic test membrane replacement device, used in the aforementioned automatic test membrane replacement device 300. The method for operating the automatic test membrane replacement device includes the following steps:

[0056] S1: Set a preset time, which is the replacement time of the test membrane;

[0057] S2: When the preset time is reached, close the first valve in the liquid inlet pipe;

[0058] S3: Drain the plating solution from the cavity;

[0059] S4: Control the first roll end to rewind the film material and replace the test film in the plating bath;

[0060] S5: Open the first valve to allow the plating solution to enter the cavity.

[0061] In step S1, the preset time is the replacement time of the test membrane 324. The replacement time of the test membrane 324 can be accurately determined by analyzing the elemental content in the plating solution and calculating the consumption of the test membrane 324. In step S2, the control component 360 specifically controls the solenoid valve 340 to close the first valve in the liquid inlet pipe 380. In step S3, the control component 360 specifically controls the solenoid valve 340 to cause the drain assembly 350 to drain the plating solution from the cavity 313. In step S4, the motor 330 controls the first roll end 321 to wind up the film material 323 until the new test membrane 324 on the film material 323 is aligned with the window. In step S5, when the control component 360 detects that the motor 330 has stopped rotating, it opens the first valve through the solenoid valve 340 and simultaneously closes the drain assembly 350, allowing the plating solution to flow into the cavity 313.

[0062] After step S3, the main viewing panel 312 is separated from the housing 311; after step S4, the main viewing panel 312 is used to cover the opening of the housing 311, thus sealing the housing 311.

[0063] It should be noted that the limitations of each step involved in this solution are not considered as limiting the order of steps, provided that they do not affect the implementation of the specific solution. The steps listed first can be executed first, later, or even simultaneously. Solutions from different embodiments can be combined and applied without conflict. As long as this solution can be implemented, they should be considered to fall within the protection scope of this application.

[0064] The above description, in conjunction with specific optional embodiments, provides a further detailed explanation of this application and should not be construed as limiting the specific implementation of this application to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of this application, and all such modifications or substitutions should be considered within the scope of protection of this application.
