[0001] This application belongs to the field of cleaning equipment, and in particular relates to a magnetic rod cleaning device, a cleaning chamber, and a cleaning equipment. Background Technology

[0002] Magnetic foreign matter (such as iron and its oxides) in battery materials can cause multiple hazards: ① Safety risks: Magnetic particles dissolve and migrate to the negative electrode during charging and discharging, forming dendrites that pierce the separator, leading to internal short circuits and thermal runaway, and even combustion or explosion; ② Performance degradation: Foreign matter damages the positive electrode lattice structure, hindering lithium-ion transport, leading to capacity decay, while also increasing internal resistance and self-discharge rate, reducing charging and discharging efficiency; ③ Shortened lifespan: During long-term cycling, metallic impurities catalyze electrolyte decomposition, accelerating the consumption of active lithium and electrode aging, shortening battery life. In addition, differences in the content of magnetic foreign matter in battery packs can lead to decreased consistency, making them prone to overcharging or over-discharging.

[0003] In the production line of new energy battery materials, magnetic rods are placed in a vibrating screen to separate magnetic substances mixed in the battery materials. Specifically, the magnetic rods are placed at the outlet of the vibrating screen so that the magnetic substances mixed in the battery materials are adsorbed onto the surface of the magnetic rods during feeding. To ensure the adsorption effect of the magnetic rods, they need to be cleaned regularly. Battery materials include positive electrode materials, positive electrode precursors, negative electrode materials, and coating materials.

[0004] Currently, the cleaning of magnetic rods is mainly done manually, which results in low efficiency, a high risk of secondary contamination, and easy damage to the surface of the magnetic rods due to misoperation. Utility Model Content

[0018] The cleaning cage housing has multiple rotating shells to switch between open and closed. When the cleaning cage housing is open, the electromagnetic component has magnetic force to attract magnetic foreign objects brushed off.

[0047] To make the above and other features and advantages of this application clearer, the application is further described below with reference to the accompanying drawings. It should be understood that the specific embodiments given herein are for the purpose of explanation to those skilled in the art and are exemplary only, not restrictive.

[0048] Figure 1 This is a schematic diagram of a cleaning device provided according to one embodiment of this application. Figure 2 This is a schematic diagram of a cleaning chamber 400 according to one embodiment of this application. Please refer to... Figure 1 and Figure 2 The cleaning equipment 1000 includes a cleaning chamber 400 and a cleaning fluid supply pipeline system 500.

[0049] The cleaning chamber 400 includes a magnetic rod cleaning device 100, a cleaning chamber housing 40, and a plurality of nozzles 44. A second chamber R2 is formed inside the cleaning chamber housing 40 to house the magnetic rod cleaning device 100.

[0050] The top side of the cleaning chamber housing 40 has a cleaning chamber door 41 that can open and close the second chamber R2. The bottom wall of the cleaning chamber housing 40 has a drain port 42 that tapers from top to bottom towards the drain port 42. Multiple nozzles 44 are disposed in the second chamber R2 and arranged near the top side of the cleaning chamber housing 40.

[0051] The cleaning fluid supply pipeline system 500 includes a pump 51, a cleaning fluid collection chamber 52, and a switching valve 53. The cleaning fluid collection chamber 52 is equipped with a filter baffle 521 to divide the cleaning fluid collection chamber 52 into a third chamber R3 and a fourth chamber R4 arranged at intervals. The third chamber R3 is connected to the drain port 42 via the switching valve 53, and the fourth chamber R4 is connected to the nozzle 44 via the pump 51.

[0052] In this embodiment, the cleaning fluid supply pipeline system 500 provides cleaning fluid to the cleaning chamber 400, and the cleaning chamber 400 is equipped with a magnetic rod cleaning device 100, which, together with the cleaning fluid, completes the cleaning of the magnetic rod 90.

[0053] Specifically, the cleaning chamber 400 has a cleaning chamber housing 40, a second chamber R2 is formed inside the cleaning chamber housing 40, and is able to contain cleaning fluid supplied from the cleaning fluid supply pipeline system 500, and is able to immerse a portion of the magnetic rod cleaning device 100 located in the second chamber R2.

[0054] A cleaning chamber door 41 is installed on the top side of the cleaning chamber housing 40 to open and close the second chamber R2. When the cleaning chamber door 41 is open, the magnetic rod 90 is placed in or unloaded into the magnetic rod cleaning device 100 in the second chamber R2. When the cleaning chamber door 41 is closed, the cleaning operation of the magnetic rod 90 is performed.

[0055] In practical applications, the cleaning chamber door 41 is a single-sided folding outward-opening cleaning chamber door, reducing the space occupied during opening. The cleaning chamber door 41 can be opened manually or with an electric assist mechanism, and can be designed according to requirements. In addition, the opening angle of the cleaning chamber door 41 relative to the top side wall of the cleaning chamber shell 40 is 110° to 160°, preferably 120°.

[0056] The cleaning fluid collection chamber 52 is used to store the cleaning fluid and is equipped with a filter baffle 521 to divide the cleaning fluid collection chamber 52 into a third chamber R3 and a fourth chamber R4. The fourth chamber R4 is located downstream of the third chamber R3 in the liquid flow direction, that is, the liquid entering the fourth chamber R4 has passed through the filter baffle 521, so the cleaning fluid in the fourth chamber R4 is clean.

[0057] In one embodiment, the filter baffle 521 employs a multi-stage filtration setup, including a coarse filter layer, a magnetic adsorption layer, and a fine filter layer. The coarse filter layer uses a multi-layer stainless steel filter screen (50μm pore size) to intercept large particulate impurities, the magnetic adsorption layer uses a permanent magnet (surface covered with PTFE filter cloth), and the fine filter layer uses a 0.2μm microporous filter membrane (material polyethersulfone) to remove colloids and organic matter.

[0058] The inlet and outlet of the pump 51 in the cleaning fluid supply pipeline system 500 are respectively connected to the fourth chamber R4 and multiple nozzles 44 on the top side of the cleaning chamber shell 40 through pipelines. The pump 51 provides power to pump the cleaning fluid in the fourth chamber R4 into the second chamber R2 through the nozzles 44.

[0059] In one embodiment, the nozzle 44 may be a high-pressure nozzle with integrated hot air blowing function. This allows for high-pressure rinsing to ensure effective cleaning and ensures no moisture residue remains in the second chamber R2. In specific applications, the pressure generated by the high-pressure nozzle is 8 MPa to 12 MPa, and the temperature of the hot air is 80℃ ± 1℃. It should be noted that the cleaning solution used here is generally a mixture containing alcohol, which is easily dried by hot air.

[0060] The bottom wall of the cleaning chamber shell 40 is provided with a drain port 42. The waste liquid generated after cleaning can be discharged into the third chamber R3 through the drain port 42. The drain port 42 and the third chamber R3 are connected by a pipeline, and a switch valve 53 is installed on the pipeline to control the discharge. In specific applications, the switch valve 53 can be an electromagnetic switch valve.

[0061] Furthermore, the bottom wall of the cleaning chamber shell 40 is tapered in the direction of liquid flow, with its diameter being smallest at the drain port 42, which is the throat, facilitating the concentrated discharge of waste liquid. In practical applications, the acute angle formed by the slope of the bottom wall and the horizontal plane is between 10° and 30°.

[0062] It should be understood that after the waste liquid is separated from impurities by the filter baffle 521, it enters the third chamber R3 to achieve the recycling of the cleaning liquid.

[0063] In one embodiment, the third chamber R3 and the fourth chamber R4 are arranged at intervals in the vertical direction, which facilitates the passage of liquid through the filter baffle 521 by utilizing gravity. In another embodiment, a liquid level sensor 54 is provided in the fourth chamber R4 to monitor the liquid level in the fourth chamber R4.

[0064] In practical applications, a dual-level monitoring scheme is adopted, which has two level thresholds: a first level threshold for replenishment and a second level threshold for alarm. These two level thresholds can be set according to requirements. Additionally, a temperature sensor 43 is installed in the second chamber R2 to confirm whether the temperature within the second chamber R2 meets the requirements.

[0065] In addition, the outer shell 40 of the cleaning chamber is connected to the fourth chamber R4 and has a waste liquid outlet (not shown in the figure). When the number of cycles of the cleaning liquid reaches the threshold, it can be discharged through the waste liquid outlet.

[0066] In one embodiment, the shell wall of the cleaning chamber outer shell 40 includes a first alloy layer, a second alloy layer, a plastic layer, and a coating layer. The first alloy layer, the second alloy layer, the plastic layer, and the coating layer are stacked sequentially from the inside out. When the cleaning chamber outer shell 40 is closed, it can shield the magnetic field, thereby avoiding interference when detecting the magnetic force of the magnetic rod or during the magnetization process of the magnetic rod.

[0067] In practical applications, the first alloy layer is made of stainless steel, with a thickness of 1.5mm to 2.5mm, serving a structural support function. The second alloy layer is made of permalloy, with a thickness of 1mm to 1.5mm, providing magnetic field shielding. The plastic layer is made of polytetrafluoroethylene (PTFE), with a thickness of 0.3mm to 0.8mm, exhibiting strong corrosion resistance. The coating is made of silicon carbide, with a thickness of 0.2mm to 0.5mm, providing wear-resistant protection. Therefore, the outer shell of the cleaning chamber 40 employs a four-layer composite material structure to achieve a balance between corrosion resistance and magnetic field shielding requirements.

[0068] It should be noted that the "inner" and "outer" relationship here is based on the center of the cleaning chamber shell 40. The part that is relatively closer to the center of the cleaning chamber shell 40 is the inner part, and the part that is relatively farther away from the center of the cleaning chamber shell 40 is the outer part.

[0069] Figure 3a This is one of the schematic diagrams of a magnetic rod cleaning apparatus 100 provided according to one embodiment of this application. Figure 3b This is a second schematic diagram of a magnetic rod cleaning apparatus 100 according to one embodiment of this application. Please refer to... Figure 3a and Figure 3b and combined Figure 2 In some alternative embodiments, the magnetic rod cleaning device 100 includes a movable cleaning cage 10 and an electromagnetic component 30.

[0070] The movable cleaning cage 10 includes a cleaning cage housing 11 and a cleaning mechanism 13 located inside the cleaning cage housing 11. The electromagnetic component 30 is disposed on the circumferential outer side of the movable cleaning cage 10.

[0071] The cleaning cage housing 11 includes multiple housings, which are configured to rotate to open or close the cleaning cage housing 11. When the cleaning cage housing 11 is open, the cleaning mechanism 13 removes foreign objects from the magnetic rod 90 placed inside the cleaning cage housing 11, and the electromagnetic component 30 generates a magnetic force to attract magnetic foreign objects.

[0072] When the outer shell 11 of the cleaning cage is closed, the first chamber R1 is formed, and the electromagnetic component 30 loses its magnetic force to dislodge magnetic foreign objects.

[0073] In this embodiment, the magnetic rod cleaning device 100 includes at least a movable cleaning cage 10 and an electromagnetic component 30. The movable cleaning cage 10 can accommodate the magnetic rod 90 and clean the magnetic rod 90, and cooperate with the electromagnetic component 30 to adsorb magnetic foreign objects that fall off the magnetic rod 90 during the cleaning process.

[0074] Specifically, the magnetic rod 90 is cleaned by the cleaning mechanism 13. The cleaning cage shell 11 has multiple rotatable shells to switch between opening and closing. The electromagnetic component 30 generates magnetic force when energized and loses magnetic force when de-energized.

[0075] With the outer shell 11 of the cleaning cage open, the cleaning mechanism 13 cleans the magnetic rod 90 to remove foreign objects from the magnetic rod 90. The foreign objects contain magnetic foreign objects, and the electromagnetic component 30 is energized and has magnetic force, so it can attract the magnetic foreign objects.

[0076] With the cleaning cage housing 11 closed, the cleaning mechanism 13 and the magnetic rod 90 are both housed within the enclosed space of the first chamber R1. When the electromagnetic component 30 is de-energized and loses its magnetic force, the magnetic foreign object cannot be re-attracted by the magnetic rod 90 due to the obstruction of the cleaning cage housing 11. It should be understood that the electromagnetic component 30 loses its magnetic force only after a preset time delay following the closure of the cleaning cage housing 11. The preset time can be 0.5s-2s.

[0077] It is evident that by working in concert with the cleaning cage 10 and the electromagnetic component 30, the risk of secondary contamination of the magnetic rod 90 by magnetic foreign objects can be effectively reduced.

[0078] In practical applications, the electromagnetic component 30 can be an electromagnet. The magnetic field strength generated by the electromagnetic component 30 is greater than that of the magnetic rod 90, ensuring that detached magnetic foreign objects can be attracted by the electromagnetic component. It also has a built-in temperature sensor to provide power-off protection in case of overheating. In addition, the outer shell 11 of the cleaning cage is made of engineering plastic, which will not be magnetized and attract magnetic foreign objects when the electromagnetic component 30 is de-energized, thus preventing secondary pollution.

[0079] Figure 4a A schematic diagram of the cleaning cage shell 11 from one perspective. Figure 4b This is a schematic diagram of the cleaning cage outer shell 11 from another perspective. Please refer to it as well. Figure 1In one alternative embodiment,

[0080] The movable cleaning cage 10 also includes a drive module 12, which drives the cleaning mechanism 13 to operate and drives at least one of the plurality of housings to rotate about the axis of the cleaning cage housing 11 to open or close the cleaning cage housing 11.

[0081] In this embodiment,

[0082] The drive module 12 is connected to the cleaning cage housing 11 and the cleaning mechanism 13. The drive module 12 can drive at least one of the multiple housings to rotate, thereby opening or closing the cleaning cage housing 11, that is, switching the cleaning cage housing 11 between an open state and a closed state. The drive module 12 can provide power to the cleaning mechanism 13 so that the cleaning mechanism 13 can perform cleaning operations.

[0083] In one embodiment, the drive module 12 includes a drive unit 121 and a transmission unit 122. The drive unit 121 provides power and transmits it to the cleaning cage housing 11 and the cleaning mechanism 13 via the transmission unit 122. In specific applications, the drive unit 121 is a motor and there are two of them. The transmission unit 122 is a gear set and also has a clutch function. That is, the clutch function unit selects the required drive unit 121 to drive the cleaning cage housing 11 or the cleaning mechanism 13. Since the cleaning cage housing 11 and the cleaning mechanism 13 have different speed requirements, they are adapted by the gear set.

[0084] In practical applications, the drive module 12 is an electrically driven actuating component, and therefore it is located outside the cleaning chamber housing 40.

[0085] In practical applications, the two axial ends of the cleaning cage shell 11 are mounted on the cleaning cage fixing bracket 116, that is, they are supported by the cleaning cage fixing bracket 116.

[0086] In a further optional embodiment, the plurality of housings includes a first housing 111, a second housing 112, a third housing 113, and a fourth housing 114.

[0087] When the outer shell 11 of the cleaning cage is closed, the first shell 111, the second shell 112, the third shell 113 and the fourth shell 114 are sequentially spliced ​​along the circumference of the outer shell 11 of the cleaning cage, and the second shell 112 and the fourth shell 114 are arranged vertically opposite each other.

[0088] When the outer shell 11 of the cleaning cage is opened, the first shell 111 overlaps with the second shell 112, and the third shell 113 overlaps with the fourth shell 114 to form openings on opposite sides of the outer shell 11 of the cleaning cage.

[0089] In this embodiment, the outer shell 11 of the washing cage is divided into four shells arranged circumferentially, corresponding to the first shell 111, the second shell 112, the third shell 113, and the fourth shell 114 (corresponding to...). Figures 3a to 4b (The parts corresponding to 1# to 4# shown).

[0090] When the outer shell 11 of the cleaning cage is closed, the four shells are sequentially spliced ​​together in the circumferential direction. The first shell 111 and the second shell 112 are located on the upper and lower sides, and the third shell 113 and the fourth shell 114 are located on the left and right sides.

[0091] The outer casing 11 of the cleaning cage has two open states. Figure 3a A schematic diagram is shown of the cleaning cage housing 11 in the first open state. In this state, the first housing 111 and the second housing 112 overlap on the upper side, and the third housing 113 and the fourth housing 114 overlap on the lower side, thus forming openings on the left and right sides. This allows the electromagnetic components located on the circumferential outer side of the movable cleaning cage 10 to attract magnetic foreign objects that fall off the magnetic rod when cleaning the magnetic rod 90.

[0092] Figure 3b A schematic diagram is shown showing the cleaning cage housing 11 in its second open state. In this state, the first housing 111 and the second housing 112 overlap on the left side, and the third housing 113 and the fourth housing 114 overlap on the right side, thus forming openings on the top and bottom sides to facilitate the loading or unloading of the magnetic rod 90. (This will be explained in detail below with reference to the magnetic rod loading mechanism 20.)

[0093] In practical applications, the first housing 111 and the third housing 113 are symmetrical from left to right, and the second housing 112 and the fourth housing 114 are symmetrical from top to bottom. Furthermore, the dimensions of the first housing 111 and the third housing 113 are slightly smaller than those of the second housing 112 and the fourth housing 114. When they overlap, the second housing 112 is located outside the first housing 111, and the fourth housing 114 is located outside the third housing 113.

[0094] As can be seen, the outer shell 11 of the cleaning cage is a symmetrical four-part hollow cylindrical shell. The two adjacent shells are close to each other and rotate to overlap. The overlapping design can reduce the space occupied.

[0095] It should be noted that, for the sake of explaining this solution, the directions of "up", "down", "left" and "right" are determined based on the directions in the attached drawings, and do not specifically limit the installation orientation of the cleaning cage shell 11.

[0096] In one embodiment, the electromagnetic element 30 is disposed on opposite sides of the movable cleaning cage 10 and aligned with the opening of the cleaning cage housing 11 when it is opened.

[0097] In this embodiment, the electromagnetic components 30 are located on the left and right sides of the movable cleaning cage 10. When the outer shell 11 of the cleaning cage is in the first open state, the electromagnetic components 30 on both sides are aligned with the openings on the left and right sides, which is conducive to adsorbing magnetic foreign objects. When the cleaning mechanism 13 is in operation, the electromagnetic components 30 are energized to form a magnetic force to adsorb magnetic foreign objects.

[0098] Please combine Figure 2 In some optional embodiments, the magnetic rod cleaning device 100 further includes a magnetic rod loading mechanism 20, which includes at least one fixed lifting member 21 and at least two movable lifting members 22. The fixed lifting member 21 and the movable lifting members 22 have lifting freedom to drive the magnetic rod to lift when the cleaning cage shell 11 is opened.

[0099] The cleaning cage housing 11 also includes a plurality of flexible components 115, which are fitted into at least one of the plurality of housings and are spaced apart along the axial direction of the cleaning cage housing 11.

[0100] The movable lifting members 22 are located near the two axial ends of the cleaning cage housing 11, and their vertical projection on the cleaning cage housing 11 is located within the corresponding flexible kit 115. The movable lifting members 22 at both ends are configured to have a degree of freedom of movement along the axial direction of the cleaning cage housing and their top ends extend into the cleaning cage housing 11 through the corresponding flexible kit 115.

[0101] The fixed lifting member 21 is located between the movable lifting members 22 on both sides, and its vertical projection on the outer shell 11 of the cleaning cage is located within the corresponding flexible kit 115. The top end of the fixed lifting member 21 extends into the outer shell 11 of the cleaning cage through the corresponding flexible kit 115.

[0102] In this embodiment, the magnetic rod loading mechanism 20 is used to load the magnetic rod 90. It consists of multiple lifting members, each of which has a degree of freedom to move up and down. The tops of these lifting members are located inside the cleaning cage shell 11. Furthermore, each lifting member has a flexible sleeve 115 aligned vertically. The top of the lifting member enters the cleaning cage shell 11 through a flexible sleeve 115.

[0103] The outer casing 11 of the cleaning cage has circumferentially spaced clearance openings. Flexible components 115 are positioned at these openings, ensuring both the sealing of the outer casing 11 and the clearance function. During the rotation of the multiple casings driven by the drive module 12, the flexible components 115 can be moved in an expanding and contracting motion.

[0104] To avoid obstructing the rotational freedom of the cleaning cage housing 11 due to the lifting components, the flexible kit 115 is a corrugated rubber sleeve in specific applications.

[0105] When the outer casing 11 of the cleaning cage is in the second open state ( Figure 3bAs shown in the diagram, openings are formed on the upper and lower sides of the outer shell 11 of the cleaning cage, so that the lifting component can drive the magnetic rod 90 to move up and down without interference.

[0106] As can be seen from the above, when the cleaning cage shell 11 is in the second open state, the magnetic rod 90 can be loaded or unloaded by the lifting component. When the cleaning cage shell 11 is in the first open state, the foreign objects on the magnetic rod 90 can be removed by the cleaning mechanism 13 in conjunction with the electromagnetic component 30.

[0107] Furthermore, among the multiple lifting components, the one with a fixed position is the fixed lifting component 21, and among the multiple lifting components, the one with axial movement freedom of the cleaning cage shell 11 is the movable lifting component 22. The number of movable lifting components 22 is not less than 2, and they are arranged close to the two axial ends of the cleaning cage shell 11.

[0108] It should be understood that by adjusting the axial distance between the movable lifting parts 22 on both sides of the cleaning cage shell 11, the magnetic rods 90 of different lengths can be adapted by axially moving the movable lifting parts 22.

[0109] It should be noted that the lifting component can be, for example, a cylinder or a hydraulic cylinder, and has a clamping function, which can be achieved by a cylinder clamp. For loading or unloading the magnetic rod 90, when the cleaning cage shell 11 is in the second open state, the fixed lifting component 21 is first raised to clamp the axial ends of the magnetic rod 90 placed by the operator, and then the magnetic rod 90 is driven back into the cleaning cage shell 11.

[0110] It should be understood that during the cleaning process, the clamping position of the fixed lifting member 21 on the magnetic rod 90 cannot be cleaned. Therefore, the movable lifting member 22 needs to lift the fixed magnetic rod 90 and then the fixed lifting member 21 needs to fall back down for further cleaning. In this way, during the cleaning process, the magnetic rod 90 is alternately fixed by the movable lifting member 22 and the fixed lifting member 21 to ensure the cleanliness of the magnetic rod 90.

[0111] It should be noted that in the illustrated embodiment, there are two fixed lifting members 21 and two movable lifting members 22, which are located on one side of the third housing 113. Therefore, the flexible kit 115 is fitted on the third housing 113 and the fourth housing 114. Of course, the number of lifting members is not limited to this.

[0112] Figure 5 This is a schematic diagram of a brush 131 provided according to one embodiment of this application. Please refer to... Figure 5 In one alternative embodiment, the cleaning mechanism 13 is a brush barrel and includes a plurality of brushes 131, which are arranged at circumferential intervals along the brush barrel.

[0113] In this embodiment, the cleaning mechanism 13 is a brush cylinder composed of multiple brushes 131 mounted on a cylindrical support. The brush cylinder is coaxially arranged with the cleaning cage housing 11, and the brushes 131 are spaced apart circumferentially along the brush cylinder. The drive module 12 can drive the brush cylinder to rotate so that the brushes 131 on it can brush the magnetic rod 90.

[0114] It should be understood that the brush barrel can agitate the cleaning fluid during rotation, the brush 131 brushes off the foreign objects on the magnetic rod 90, the agitated cleaning fluid can carry out the foreign objects, and the magnetic foreign objects in the foreign objects are attracted by the magnetic force of the energized electromagnetic component 30.

[0115] Furthermore, the brush 131 includes a main brush section 1311 and an end brush section 1312. The main brush section 1311 extends along the axial direction of the cleaning cage housing 11, and the end brush sections 1312 are located at both ends of the main brush 131.

[0116] Understandably, the main brush section 1311 brushes the peripheral sidewall of the magnetic rod 90, and the end brush sections 1312 at both ends brush the axial end sidewall of the magnetic rod 90.

[0117] In this way, the brush 131 can clean the magnetic rod 90 from all directions and work in conjunction with the electromagnetic component 30 to achieve both physical cleaning and magnetic adsorption of foreign objects.

[0118] In a further optional embodiment, the cleaning device 1000 also includes a detection system 600, which includes a detection module 61 and a linear guide module 62.

[0119] At least a portion of the linear guide module 62 is located within the second chamber R2, and the detection module 61 is connected to the linear guide module 62 and configured to enter or leave the second chamber R2 under the drive of the linear guide module 62.

[0120] The detection module 61 is used to measure the magnetic field strength of the magnetic rod, scan the internal defects of the magnetic rod, and acquire surface image data of the magnetic rod.

[0121] In this embodiment, the detection system 600 is used to detect the magnetic rod 90. Specifically, during the cleaning process, the detection module 61 is located outside the outer shell 40 of the cleaning chamber. After the cleaning is completed, the detection module 61 enters the second chamber R2 under the drive of the linear guide module 62 to collect data of the magnetic rod 90 and to confirm whether the magnetic rod 90 meets the requirements.

[0122] In one optional embodiment, the detection module 61 includes a magnetic field detection unit, an ultrasonic detection unit, and an image acquisition unit. The magnetic field detection unit measures the magnetic field strength of the magnetic rod 90, the ultrasonic detection unit scans for internal defects in the magnetic rod 90, and the image acquisition unit acquires surface image data of the magnetic rod 90.

[0123] In specific applications, the magnetic field detection unit is a gaussmeter to monitor the magnetic field strength, the ultrasonic detection unit is an ultrasonic flaw detector to obtain internal defects of the magnetic rod 90, and the image acquisition unit is an industrial camera to obtain image data of the magnetic rod 90.

[0124] In one optional embodiment, the linear guide module 62 is a linear module, such as a synchronous belt type linear module, a lead screw type linear module, a linear motor type module, etc.

[0125] In some alternative embodiments, the cleaning device 1000 further includes a magnetizer 70, which is connected to the magnetic rod loading mechanism 20 in the magnetic rod cleaning device 100.

[0126] In this embodiment, when the magnetic field strength of the magnetic rod 90 is insufficient, the magnetizer 70 is used to magnetize the magnetic rod 90 to ensure the magnetic field strength of the magnetic rod 90.

[0127] In one optional embodiment, the magnetizer 70 is connected to the movable lifting member 22 of the magnetic rod loading mechanism 20 and is configured to apply a pulsed current to the movable lifting member 22, thereby transmitting the pulsed current to the magnetic rod 90 to magnetize it. That is, pulsed magnetization technology is used to restore the magnetism of the magnetic rod 90.

[0128] Figure 6 This is a block diagram showing the connection relationships of a control system 800 according to one embodiment of this application. Please refer to... Figure 6 In a further optional embodiment, the cleaning equipment 1000 also includes a control system 800, which is electrically connected to the cleaning chamber 400, the cleaning fluid supply pipeline system 500, the detection system 600 and the magnetizer 70, and is used to control the cleaning chamber 400, the cleaning fluid supply pipeline system 500, the detection system 600 and the magnetizer 70 to work together to complete the cleaning and magnetization repair of the magnetic rod.

[0129] In this embodiment, the control system 800 is connected to the magnetic rod cleaning device 100 in the cleaning chamber 400. It can control the operation of the drive module 12 to control the switching state of the cleaning cage shell 11 and the operation of the cleaning mechanism 13. In specific applications, the cleaning cage shell 11 is equipped with a position sensor to determine the state of the cleaning cage shell 11.

[0130] In addition, the control system 800 can also control the operation of the magnetic rod loading mechanism 20 and the electromagnetic component 30, namely the lifting position of each lifting component in the magnetic rod loading mechanism 20 and the on / off power of the electromagnetic component 30. In summary, the control system 800 can control the cleaning cage shell 11, the magnetic rod loading mechanism 20 and the electromagnetic component 30 to work together to physically scrub foreign objects on the magnetic rod 90 and electromagnetically attract magnetic foreign objects.

[0131] The control system 800 is also connected to the nozzle 44 and temperature sensor 43 in the cleaning chamber 400. The nozzle 44 can move to control the spray angle to ensure coverage and to obtain the temperature data of the cleaning fluid in the second chamber R2 sent by the temperature sensor 43.

[0132] The control system 800 is also connected to the pump 51, switch valve 53, liquid level sensor 54 and other components in the cleaning fluid supply pipeline system 500 to monitor the liquid level information in real time, issue an alarm when the liquid level is too low, and control the operation of the pump 51 and switch valve 53 to achieve automatic circulation of the cleaning fluid.

[0133] The control system 800 is also connected to the detection module 61 and the linear guide module 62 in the detection system 600 to obtain the information of the magnetic rod 90 obtained by the detection module 61, and can control the position of the detection module 61 by controlling the linear guide module 62.

[0134] In practical applications, the control system 800 integrates an automatic recognition model, which is trained based on a convolutional neural network. Specifically, it is trained based on tens of thousands of magnetic rod surface image data to automatically determine whether the cleanliness meets the standards.

[0135] The control system 800 is also connected to the magnetizer 70. When the magnetic field information obtained by the detection module 61 confirms that the magnetic field of the magnetic rod 90 is insufficient, the magnetizer 70 is controlled to perform magnetization repair.

[0136] In summary, the control system 800 controls the coordinated operation of each component to achieve automated cleaning of the magnetic rod 90 and magnetization repair operations.

[0137] In specific applications, the cleaning equipment 1000 also includes a housing 1001, and the components of the cleaning equipment 1000 are integrated inside the housing 1001. The control system 800 has at least a control module and a control panel 81. The control panel 81 is located on the top side of the housing 1001. That is, various required control parameters and control commands can be input through the control panel 81, and the collected data information can also be obtained.

[0138] In one optional embodiment, the control module can be a combination of a lower-level machine (such as a microcontroller or a programmable logic controller (PLC)) and a higher-level machine (computer). The lower-level machine controls various actuators and acquires data collected by sensors, while the higher-level machine can be configured with an automatic recognition model.

[0139] Furthermore, the side wall of the housing 1001 is also provided with a cleaning fluid filling port 55, through which the cleaning fluid is added to the cleaning fluid collection chamber 52.

[0140] To facilitate understanding of this plan, the following explanation will be based on practical operation.

[0141] I. Equipment Start-up Preparation

[0142] Equipment positioning and inspection: Move the equipment to the designated location, check the liquid level in the cleaning fluid collection chamber 52, and confirm that the cleaning fluid formula and concentration meet the requirements; check the sealing of the filter baffle 521 and pipelines to ensure there is no leakage; if a mobile power module is used, check that the power is ≥80%; if powered by a power cord, confirm that the connection is secure and the length is appropriate.

[0143] System initialization: Connect the power supply, start the control system 800, and initialize the equipment; verify that the liquid level sensor 54 and temperature sensor 43 are functioning normally.

[0144] II. Operation Selection and Parameter Input

[0145] Operators input magnetic rod parameters (length, material, magnetic field strength, etc.) through the control panel 81, and the system automatically matches parameters such as cleaning fluid temperature, brush speed, and electromagnet magnetic field strength.

[0146] III. Fixed placement of magnetic rods

[0147] Cleaning chamber door opening: Open the cleaning chamber door 41. The cleaning cage outer shell 11 is initially in a closed state. After starting, the second shell 112 and the fourth shell 114 rotate to the left and right sides respectively, overlapping with the first shell 111 and the third shell 113 respectively, so as to form an opening in the vertical direction.

[0148] Magnetic rod loading: The fixed lifting component 21 automatically rises to the designated position, places the magnetic rod 90 on the fixed lifting component 21 and automatically locks the magnetic rod 90, and the fixed lifting component 21 automatically returns to the designated position;

[0149] After closing the cleaning chamber door 41, the system checks the sealing status and then enters the cleaning mode.

[0150] IV. Cleaning Process Implementation

[0151] After the cleaning program is started, the fixed lifting component 21 is lowered to the cleaning position, and cleaning fluid is added into the cleaning chamber 400 until the cleaning fluid submerges the magnetic rod cleaning device 100.

[0152] The first shell 111 and the second shell 112, as well as the third shell 113 and the fourth shell 114 of the cleaning cage 11, rotate simultaneously from their original overlapping positions to the upper and lower sides. The openings on the left and right sides expose the magnetic rod 90 to the electromagnetic component 30. The electromagnetic component 30 is energized to attract magnetic foreign objects, and the brush cylinder brushes the magnetic rod 90 at a set speed.

[0153] After the first cleaning is completed, the fixed lifting component 21 descends, and the movable lifting component 22 rises to lift and perform a second cleaning.

[0154] After cleaning is completed, the outer shell of the cleaning cage 11 rotates to switch to the closed state. The outer shell of the cleaning cage 11 closes first, and after a delay of 0.5s-2s, the power is cut off and the electromagnet is demagnetized.

[0155] V. Drainage and pollution prevention

[0156] After the electromagnet is demagnetized, foreign objects and other foreign matter on the electromagnet are quickly discharged through the bottom micro-funnel along with the cleaning fluid (drainage time ≤ 30 seconds) and enter the third chamber R3; the outer shell 11 of the cleaning cage covers the magnetic rod 90 to prevent magnetic foreign matter from being attracted to the magnetic rod 90 again.

[0157] VI. Automated Detection

[0158] The detection module 61 enters the cleaning chamber 400 through the linear guide module 62 and performs the following actions in sequence: the magnetic field detection unit measures the magnetic field strength of the magnetic rod 90; the ultrasonic detection unit scans the internal defects of the magnetic rod 90; and the image acquisition unit determines the cleanliness of the magnetic rod 90.

[0159] VII. Magnetization Repair

[0160] If the magnetic field strength of the magnetic rod 90 is not up to standard (e.g., below 60% of the set value), a pulse current (e.g., peak value 500A ± 5%, pulse width 10ms) is applied via the magnetizer 70 through the movable lifting component 22.

[0161] Repeat the test after applying magnetization until the magnetic field recovery rate is ≥95%.

[0162] 8. Self-cleaning and drying

[0163] First self-cleaning: Nozzle 44 washes the inner wall of the chamber at high pressure and multiple angles, and the wastewater is discharged through the bottom micro funnel of the outer shell 40 of the cleaning chamber;

[0164] Hot air drying: The air outlet integrated on nozzle 44 blows out hot air at 80℃±1℃ for 2 minutes to ensure that there is no moisture residue in the chamber;

[0165] Second self-cleaning: After the operator removes the magnetic rod, the system automatically starts a second high-pressure cleaning and drying process.

[0166] In the description of this application, the use of terms such as "first" and "second" is merely for the convenience of describing similar features and is not intended to limit the number of such features.

[0167] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
