Description

Technical Field

[0001] This utility model relates to the field of electronic component cleaning technology, specifically to a multi-stage automatic cleaning device. Background Technology

[0002] The industrial wastewater discharged by chip factories contains flocculants and calcium. 2+ SO4 2- PO4 3- Various impurities and unknown ions can cause fluoride ion sensors to adsorb these substances during long-term measurements, interfering with measurement stability and accuracy and shortening the sensor's lifespan.

[0003] Normally, using dilute hydrochloric acid to descale fluoride ion meter sensors will leave some difficult-to-remove impurities and unknown ions. Improper operation may cause sensor passivation, and there are certain safety risks to operators when they come into contact with dilute hydrochloric acid.

[0004] Therefore, prolonged immersion of the sensor in ultrapure water after cleaning with dilute hydrochloric acid can remove impurities and unknown ions that are difficult to remove with dilute hydrochloric acid from the lanthanum fluoride single crystal film of the sensor, improve measurement stability and accuracy, solve the sensor passivation problem, and extend the sensor's service life.

[0005] However, due to the high cost of mobile equipment, current methods for cleaning fluoride ion sensors only achieve automated cleaning when using dilute hydrochloric acid. Afterward, manual movement is still required to transfer the fluoride ion sensor to ultrapure water for cleaning, and additional equipment is needed to drive the object to stir and clean it during the cleaning process. This is not conducive to improving cleaning efficiency, and the dilute hydrochloric acid used in the cleaning process can cause harm to the human body. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-stage automatic cleaning device. This cleaning device can quickly and accurately move the objects to be cleaned to the corresponding cleaning tank for multi-stage cleaning, and has the advantages of high automation, good cleaning effect and low cost.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] Provides multi-stage automatic cleaning devices, including:

[0009] Several cleaning tanks, each filled with cleaning solution;

[0010] It is equipped with multiple cleaning tanks, each of which can be filled with different cleaning solutions to achieve multi-stage cleaning.

[0011] A movable rod assembly is used to hang an object to be cleaned, and the movable rod assembly drives the object to be cleaned to move in the vertical direction, the horizontal direction, and the horizontal plane;

[0012] Since the items to be cleaned are hung on the movable rod assembly, the movable rod assembly can be moved to the corresponding cleaning tank.

[0013] A controller is connected to the moving rod assembly, and the controller controls the moving rod assembly to move the object to be cleaned to the corresponding cleaning tank according to the cleaning program.

[0014] The controller can automatically place the objects to be cleaned into the corresponding cleaning tank through a programmed setting.

[0015] In some embodiments, the object to be cleaned is a fluoride ion sensor, and the plurality of cleaning tanks are divided into an acid washing tank, a water washing tank, and an immersion tank. The acid washing tank is filled with dilute hydrochloric acid, and the water washing tank and the immersion tank are filled with ultrapure water, respectively.

[0016] Due to the deposition of flocculents and Ca on the surface of the fluoride ion sensor 2+ SO4 2- PO4 3- Various impurities and unknown ions are present. Descaling the fluoride ion sensor with dilute hydrochloric acid leaves some difficult-to-remove impurities and unknown ions. Prolonged immersion in ultrapure water after cleaning with dilute hydrochloric acid removes these impurities and unknown ions from the lanthanum fluoride single-crystal film. Therefore, an acid washing tank, a water washing tank, and an immersion tank are provided. The acid washing tank contains dilute hydrochloric acid, while the water washing tank and the immersion tank contain ultrapure water. Through the coordination of the moving rod assembly and the controller, the fluoride ion sensor, mounted on the moving rod assembly, sequentially enters the acid washing tank, water washing tank, and immersion tank for cleaning according to a program.

[0017] In some embodiments, the movable rod assembly includes a lifting rod and a telescopic rod, one end of the telescopic rod being rotatably connected to the lifting rod, and the other end of the telescopic rod being used to hang the object to be cleaned.

[0018] The lifting rod drives the telescopic rod to rise and fall in the vertical direction, the telescopic rod drives the object to be cleaned to move horizontally, and the telescopic rod drives the object to be cleaned to swing on the horizontal plane by rotating around the lifting rod.

[0019] The lifting rod drives the telescopic rod to rise and fall vertically. The telescopic rod is a horizontal rod that can extend and retract horizontally. Since the telescopic rod is rotatably connected to the lifting rod, the telescopic rod can also rotate around the lifting rod, thus enabling the telescopic rod to rotate on the horizontal plane. This allows the fluoride ion sensor mounted on the moving rod assembly to move into the corresponding cleaning tank.

[0020] In some embodiments, a motor is provided at the top of the lifting rod, and the output shaft of the motor is connected to the telescopic rod and drives the telescopic rod to rotate.

[0021] The motor output shaft can rotate, so the telescopic rod is connected to the motor output shaft, thereby driving the telescopic rod to rotate.

[0022] In some embodiments, the probe of the fluoride ion sensor is vertically pointed towards each cleaning tank.

[0023] Since the probe of the fluoride ion sensor needs to be cleaned, and the probe is pointing vertically downwards, it can be vertically inserted into the corresponding cleaning tank for cleaning.

[0024] In some embodiments, the end of the telescopic rod is provided with a retaining ring, the axis of which is in the same direction as the length of the lifting rod, and the probe of the fluoride ion sensor passes through the retaining ring and is engaged with the retaining ring.

[0025] The retaining ring allows the fluoride ion sensor to be detachably mounted on the telescopic rod and keeps the probe of the fluoride ion sensor vertically downward.

[0026] In some embodiments, each cleaning tank is equipped with a level gauge, which is connected to the controller.

[0027] This level gauge is used to monitor the liquid level in each cleaning tank, ensuring that the cleaning fluid in the tank is sufficient and does not overflow.

[0028] In some embodiments, the pickling tank is connected to a first inlet pump, a first inlet valve, and a first drain valve. The first inlet pump, the first inlet valve, and the first drain valve are respectively connected to the controller, and the first drain valve is located at the bottom of the pickling tank.

[0029] When dilute hydrochloric acid needs to be added to the pickling tank, the controller controls the first inlet pump and the first inlet valve to open, and the dilute hydrochloric acid is added to the pickling tank. After the dilute hydrochloric acid is filled, the first inlet pump and the first inlet valve are closed. After the pickling of the items in the pickling tank is completed, the controller controls the opening of the first drain valve to discharge the dilute hydrochloric acid in the pickling tank.

[0030] In some embodiments, the washing tank is connected to a second inlet pump, a second inlet valve, and a second drain valve. The second inlet pump, the second inlet valve, and the second drain valve are respectively connected to the controller, and the second drain valve is located at the bottom of the washing tank.

[0031] When ultrapure water needs to be added to the washing tank, the controller controls the second inlet pump and the second inlet valve to open, and then the ultrapure water is added to the washing tank. After the ultrapure water is filled, the controller closes the second inlet pump and the second inlet valve. After the items in the washing tank are cleaned, the controller controls the second drain valve to open and drain the ultrapure water from the washing tank.

[0032] In some embodiments, the soaking tank is connected to a third inlet pump, a third inlet valve, and a third outlet valve. The third inlet pump, the third inlet valve, and the third outlet valve are respectively connected to the controller, and the third outlet valve is located at the bottom of the soaking tank.

[0033] When ultrapure water needs to be added to the soaking tank, the controller controls the third inlet pump and the third inlet valve to open, and then the ultrapure water is added to the soaking tank. After the ultrapure water is filled, the controller closes the third inlet pump and the third inlet valve. After the objects in the soaking tank are soaked, the controller controls the third drain valve to open and drain the ultrapure water from the soaking tank.

[0034] The beneficial effects of this multi-stage automatic cleaning device:

[0035] This utility model's multi-stage automatic cleaning device, due to the setting of multiple cleaning tanks and the assembly of a moving rod assembly, can move the object to be cleaned in the vertical, horizontal, and horizontal directions. This allows the object to be cleaned to automatically move to the corresponding cleaning tank according to the controller's control program, and can also rotate within the corresponding cleaning tank for cleaning through horizontal movement. This achieves multi-stage cleaning without the need for manual movement of the object to be cleaned or additional equipment to agitate the object during cleaning, and has the advantages of high automation and low cost.

[0044] Example 1

[0045] For the multi-stage automatic cleaning device disclosed in this embodiment, please refer to [link / reference needed]. Figure 1 ,include:

[0046] Several cleaning tanks, each filled with cleaning solution;

[0047] It is equipped with multiple cleaning tanks, each of which can be filled with different cleaning solutions to achieve multi-stage cleaning.

[0048] A movable rod assembly is used to hang an object to be cleaned, and the movable rod assembly drives the object to be cleaned to move in the vertical direction, the horizontal direction, and the horizontal plane;

[0049] Since the items to be cleaned are hung on the movable rod assembly, the movable rod assembly can be moved to the corresponding cleaning tank.

[0050] A controller is connected to the moving rod assembly, and the controller controls the moving rod assembly to move the object to be cleaned to the corresponding cleaning tank according to the cleaning program.

[0051] The controller can automatically place the objects to be cleaned into the corresponding cleaning tank through a programmed setting.

[0052] This utility model's multi-stage automatic cleaning device, due to the setting of multiple cleaning tanks and the assembly of a moving rod assembly, can move the object to be cleaned in the vertical, horizontal, and horizontal directions. This allows the object to be cleaned to automatically move to the corresponding cleaning tank according to the controller's control program, and can also rotate within the corresponding cleaning tank for cleaning through horizontal movement. This achieves multi-stage cleaning without the need for manual movement of the object to be cleaned or additional equipment to agitate the object during cleaning, and has the advantages of high automation and low cost.

[0053] The device is equipped with multiple cleaning tanks, each of which can be filled with different cleaning solutions to meet the cleaning needs at different stages.

[0054] This component is used to hang items to be cleaned and can move these items vertically, horizontally, and on a horizontal plane. This design allows the items to be cleaned to be automatically moved into different cleaning tanks. The controller is connected to the moving rod assembly and can control the moving rod assembly according to a preset cleaning program, so that the items to be cleaned can be automatically moved into the corresponding cleaning tank.

[0055] By moving on a horizontal plane, the device can also rotate objects within the cleaning tank for a more comprehensive cleaning effect. This device can automatically complete multi-stage cleaning processes without manual intervention, increasing the level of automation. Due to the reduction in manual operation and additional agitation equipment, this device has a cost advantage.

[0056] Example 2

[0057] For instructions on cleaning fluoride ion sensor 1, please refer to [link / reference]. Figures 1-3 Based on Example 1, the following content is disclosed:

[0058] The object to be cleaned is a fluoride ion sensor 1. The cleaning tanks are divided into an acid washing tank 2, a water washing tank 3, and an immersion tank 4. The acid washing tank 2 is filled with dilute hydrochloric acid, and the water washing tank 3 and the immersion tank 4 are filled with ultrapure water.

[0059] Because the surface of the fluoride ion sensor 1 is deposited with various impurities and unknown ions such as flocculants, Ca2+, SO42-, and PO43-, using dilute hydrochloric acid to descale the fluoride ion sensor 1 will leave some impurities and unknown ions that are difficult to remove. Soaking the sensor in ultrapure water for a long time after cleaning with dilute hydrochloric acid can remove the impurities and unknown ions on the lanthanum fluoride single crystal film of the sensor that are difficult to remove with dilute hydrochloric acid. Therefore, an acid washing tank 2, a water washing tank 3, and an immersion tank 4 are respectively set up. The acid washing tank 2 is filled with dilute hydrochloric acid, and the water washing tank 3 and the immersion tank 4 are filled with ultrapure water. With the cooperation of the moving rod assembly and the controller, the fluoride ion sensor 1, which is hung on the moving rod assembly, can enter the acid washing tank 2, the water washing tank 3, and the immersion tank 4 in sequence according to the program for cleaning.

[0060] In this embodiment, the movable rod assembly includes a lifting rod 5 and a telescopic rod 6. One end of the telescopic rod 6 is rotatably connected to the lifting rod 5, and the other end of the telescopic rod 6 is used to hang the object to be cleaned.

[0061] The lifting rod 5 drives the telescopic rod 6 to rise and fall in the vertical direction, the telescopic rod 6 drives the object to be cleaned to move horizontally, and the telescopic rod 6 drives the object to be cleaned to swing on the horizontal plane by rotating around the lifting rod 5.

[0062] The lifting rod 5 drives the telescopic rod 6 to rise and fall in the vertical direction. The telescopic rod 6 is a horizontal rod and can extend and retract in the horizontal direction. Since the telescopic rod 6 is rotatably connected to the lifting rod 5, the telescopic rod 6 can also rotate around the lifting rod 5, so that the telescopic rod 6 can rotate on the horizontal plane. This allows the fluoride ion sensor 1, which is hung on the moving rod assembly, to move into the corresponding cleaning tank.

[0063] Specifically,

[0064] The moving rod assembly consists of two parts: a lifting rod 5 and a telescopic rod 6. The lifting rod 5 is responsible for vertical movement, while the telescopic rod 6 is responsible for horizontal movement and rotation.

[0065] One end of the telescopic rod 6 is rotatably connected to the lifting rod 5. This design allows the telescopic rod 6 to move up and down in the vertical direction while also rotating around the lifting rod 5, thus achieving swinging on the horizontal plane.

[0066] The lifting rod 5 drives the telescopic rod 6 to rise and fall vertically, which can move the items to be cleaned into cleaning tanks at different heights.

[0067] The telescopic rod 6 acts as a horizontal rod, allowing it to extend and retract in the horizontal direction, thus enabling the object to be cleaned to be moved from one cleaning tank to another.

[0068] Because of the rotatable connection between the telescopic rod 6 and the lifting rod 5, the telescopic rod 6 can rotate around the lifting rod 5, achieving oscillation on the horizontal plane. This oscillation helps to clean objects from all angles in the cleaning tank.

[0069] The design of this movable rod assembly makes the cleaning process more flexible and efficient, adapting to objects of different shapes and sizes, as well as different layouts of cleaning tanks. By precisely controlling the movement of the lifting rod 5 and the telescopic rod 6, accurate positioning of objects and all-around cleaning can be achieved.

[0070] In this embodiment, a motor is provided at the top of the lifting rod 5, and the output shaft of the motor is connected to the telescopic rod 6 and drives the telescopic rod 6 to rotate.

[0071] The motor output shaft can rotate, so the telescopic rod 6 is connected to the motor output shaft, thereby driving the telescopic rod 6 to rotate.

[0072] In this embodiment, the probe of the fluoride ion sensor 1 is vertically pointed towards each cleaning tank.

[0073] Since the probe of the fluoride ion sensor 1 needs to be cleaned, and the probe is pointing vertically downwards, the probe can be vertically inserted into the corresponding cleaning tank for cleaning.

[0074] In this embodiment, the end of the telescopic rod 6 is provided with a retaining ring, the axis of which is the same as the length direction of the lifting rod 5, and the probe of the fluoride ion sensor 1 passes through the retaining ring and is snapped onto the retaining ring.

[0075] The retaining ring allows the fluoride ion sensor 1 to be detachably mounted on the telescopic rod 6 and ensures that the probe of the fluoride ion sensor 1 is vertically downward.

[0076] Specifically,

[0077] The probe of the fluoride ion sensor 1 is designed to point vertically downwards, ensuring it can be inserted vertically into the cleaning tank for cleaning. This vertical downward design facilitates full contact between the probe and the cleaning solution, ensuring effective cleaning. A retaining ring is located at the end of the telescopic rod 6, with its axis aligned with the length of the lifting rod 5. The probe of the fluoride ion sensor 1 passes through this retaining ring and is secured to it. This design allows for easy disassembly and installation of the fluoride ion sensor 1 on the telescopic rod 6. The retaining ring design ensures the probe is fixed to the telescopic rod 6 while maintaining its vertical downward orientation, which is crucial for probe cleaning and normal sensor operation. The retaining ring design allows for quick disassembly and installation of the fluoride ion sensor 1, facilitating maintenance and probe replacement. The vertical design of the probe ensures full contact with the cleaning solution, improving cleaning efficiency. The retaining ring provides a stable fixing point, ensuring the probe will not fall off due to vibration or movement during cleaning.

[0078] In this embodiment, each cleaning tank is equipped with a level gauge 7, and the level gauge 7 is connected to the controller.

[0079] The level gauge 7 is used to monitor the liquid level in each cleaning tank, ensuring that the cleaning fluid in the tank is sufficient and does not overflow.

[0080] In this embodiment, the pickling tank 2 is connected to a first inlet pump 8, a first inlet valve 9, and a first drain valve 10. The first inlet pump 8, the first inlet valve 9, and the first drain valve 10 are respectively connected to the controller. The first drain valve 10 is located at the bottom of the pickling tank 2.

[0081] When dilute hydrochloric acid needs to be added to pickling tank 2, the controller controls the first inlet pump 8 and the first inlet valve 9 to open and add dilute hydrochloric acid to pickling tank 2. After the dilute hydrochloric acid is filled, the first inlet pump 8 and the first inlet valve 9 are closed. After the pickling of the items in pickling tank 2 is completed, the controller controls the opening of the first drain valve 10 to discharge the dilute hydrochloric acid in pickling tank 2.

[0082] In this embodiment, the washing tank 3 is connected to a second inlet pump 11, a second inlet valve 12, and a second drain valve 13. The second inlet pump 11, the second inlet valve 12, and the second drain valve 13 are respectively connected to the controller. The second drain valve 13 is located at the bottom of the washing tank 3.

[0083] When ultrapure water needs to be input into the washing tank 3, the controller controls the second inlet pump 11 and the second inlet valve 12 to open, inputting ultrapure water into the washing tank 3. After the ultrapure water is filled, the second inlet pump 11 and the second inlet valve 12 are closed. After the washing tank 3 has finished cleaning the items, the controller controls the second drain valve 13 to open and discharge the ultrapure water in the washing tank 3.

[0084] In this embodiment, the soaking tank 4 is connected to a third inlet pump 14, a third inlet valve 15 and a third drain valve 16. The third inlet pump 14, the third inlet valve 15 and the third drain valve 16 are respectively connected to the controller. The third drain valve 16 is located at the bottom of the soaking tank 4.

[0085] When ultrapure water needs to be introduced into the soaking tank 4, the controller controls the third inlet pump 14 and the third inlet valve 15 to open, and introduce ultrapure water into the soaking tank 4. After the ultrapure water is filled, the third inlet pump 14 and the third inlet valve 15 are closed. After the objects in the soaking tank 4 are soaked, the controller controls the opening of the third drain valve 16 to drain the ultrapure water in the soaking tank 4.

[0086] Specifically, such as Figures 2-3 As shown, the connection relationship between the controller and each component and the corresponding control panel settings are illustrated.

[0087] To further explain the method by which the multi-stage automatic cleaning device cleans the fluoride ion sensor 1, the following is disclosed:

[0088] The first inlet valve 9 is connected to the dilute hydrochloric acid inlet pipe on the pickling tank 2, and the first inlet pump 8 is connected to the dilute hydrochloric acid storage tank inlet pump; the first drain valve 10 is set at the bottom, and the first drain valve 10 is connected to the waste liquid collection pipe.

[0089] The upper parts of the washing tank 3 and the soaking tank 4 are respectively connected to the second liquid inlet valve 12 and the third liquid inlet valve 15, and connected to the second liquid inlet pump 11 and the third liquid inlet pump 14 of the ultrapure water tank. The bottom is provided with the second drain valve and the third drain valve respectively, and connected to the wastewater collection pipe.

[0090] The PLC controller controls the pumps and valves of the three water tanks, enabling automatic liquid filling and drainage.

[0091] Each cleaning tank is equipped with a liquid level sensor, and the inlet valve closes when the liquid level is reached.

[0092] No manual intervention is required during the cleaning and activation process; after the cleaning and activation steps are completed, the bottom drain valve opens to complete the automatic draining.

[0093] The moving rod assembly consists of a vertically lifting rod 5 and a horizontally telescopic rod 6, which can realize the movement and stirring of fluoride ions between the pickling tank 2, the washing tank 3, and the soaking tank 4. The time for regular cleaning and soaking can be adjusted and set through the controller to realize automated regular maintenance and avoid interference from manual operation.

[0094] Step 1: Pickling

[0095] Fluoride ion sensor 1 is fixed on telescopic rod 6. It is first cleaned in pickling tank 2. The telescopic rod 6 rises and falls through the vertical part of the lifting rod 5 and extends and shortens through the horizontal part. It rotates and stirs in pickling tank 2 for no more than 20 seconds.

[0096] Step 2: Wash with water

[0097] As the horizontal section of the telescopic rod 6 shortens, the sensor moves into the washing tank 3 and is stirred again;

[0098] Steps 1 and 2 can be repeated multiple times, and the number of repetitions can be set in the controller.

[0099] Step 3: Soaking

[0100] The telescopic rod 6 rotates and the length of the horizontal section is adjusted to move the cleaned sensor into the soaking tank 4 and let it stand in ultrapure water to activate the sensor; the standing time can be set by the controller (not less than 4 hours);

[0101] After soaking, the telescopic rod 6 rises, the sensor leaves the water surface, and the sensor can be manually removed.

[0102] The above-described cleaning method for the fluoride ion sensor 1 enables automatic cleaning and activation of the fluoride ion sensor 1: the time for each step can be set on the controller to avoid malfunctions such as passivation of the fluoride ion sensor 1 caused by improper manual operation, achieving regular cleaning, reducing labor costs, and extending service life; the rotatable and telescopic fixed rod enables the fluoride ion sensor 1 to move, stir, and soak between different cleaning tanks, and the moving distance and speed can be adjusted according to actual needs using the controller; automatic liquid inlet and outlet avoid the safety risks of manual contact with dilute hydrochloric acid;

[0103] Reduce measurement interference and extend sensor life: Adding an ultrapure water activation step removes impurities and unknown ions that cannot be removed by dilute hydrochloric acid, which can reduce their interference with the measurement and improve the measurement stability and accuracy of the sensor; it can also restore the sensor to normal measurement function and extend the sensor's lifespan.
