Description

Technical Field

[0001] This application relates to the field of resistor cleaning equipment, and more particularly to an automatic resistor cleaning device. Background Technology

[0002] Zinc oxide resistance elements, also commonly known as metal oxide resistance elements or ZnO varistors, are a core component of modern surge arresters. In metal oxide surge arresters, zinc oxide resistance elements are usually not used individually, but rather composed of multiple elements connected in series, forming the core component of the arrester. They directly determine some key performance characteristics of the surge arrester, such as insulation coordination, current carrying capacity, and service life.

[0003] To ensure the performance of resistor sheets, a resistor sheet cleaning device already exists on the market, which uses ultrasonic cleaning to remove residues after resistor sheet grinding. However, this resistor sheet cleaning device is generally used in the resistor sheet manufacturing process before aluminum spraying.

[0004] The above-mentioned resistor cleaning equipment cannot be used after the resistor is processed because: if ultrasonic cleaning is used, the aluminum surface of the finished resistor will become damp, affecting the clarity of the markings on the aluminum surface. In addition, the finished resistor requires high dryness. If moisture remains on the finished resistor after ultrasonic cleaning, it will affect the performance of the surge arrester after assembly.

[0005] Therefore, the current common method for cleaning finished resistor sheets is manual wiping. Specifically, a cleaning strip is soaked in anhydrous alcohol, and the finished resistor sheets are manually wiped using the cleaning strip. However, manual cleaning is labor-intensive and inefficient. Summary of the Invention

[0006] To improve cleaning efficiency and save manpower, this application provides an automatic cleaning device for resistor sheets.

[0007] This application provides an automatic cleaning device for resistor sheets, which adopts the following technical solution:

[0008] An automatic cleaning device for resistor sheets includes a wiping mechanism and a carrier plate. The wiping mechanism includes a wiping drive assembly, a wiping cloth, and a rotation drive assembly. The wiping drive assembly drives the wiping cloth to move above the carrier plate. The wiping cloth is used to wipe the circumferential sidewalls of the resistor sheets. Multiple rollers are rotatably arranged on the carrier plate, and each roller is arranged radially. The rotation drive assembly drives each roller to rotate synchronously and in the same direction. Adjacent rollers drive multiple resistor sheets to rotate.

[0009] By adopting the above technical solution, a highly efficient and automated resistor cleaning solution is provided. Through the coordinated work of the wiping mechanism and the carrier plate, automatic wiping of the circumferential sidewalls of the resistor is achieved. The wiping drive component can precisely control the movement of the wiping cloth above the resistor, while the rotation drive component drives multiple rollers to rotate synchronously in the same direction, causing the resistor to rotate between the rollers. This ensures that the wiping cloth can thoroughly and evenly clean the outer surface of the resistor, significantly improving cleaning efficiency and consistency, reducing manual intervention, and meeting the high-standard cleaning requirements of finished resistors.

[0010] Optionally, the rotation drive assembly includes a rotation drive source, sprockets and a chain. The rotation drive source is used to drive one of the rollers to rotate. The sprockets are provided in multiple ways and are fixedly sleeved on different rollers. The chain passes around each sprocket in sequence and meshes with each sprocket.

[0011] By adopting the above technical solution, the synchronous rotation of multiple rollers is achieved through the transmission structure of sprockets and chains. This ensures that all resistance elements rotate evenly and coordinately during the cleaning process, avoiding cleaning dead spots or damage to resistance elements caused by asynchronous rotation. The rotation drive source only needs to drive one roller to drive the other rollers via chain transmission, saving energy. The structure is simple and reliable, reducing equipment complexity and manufacturing costs, while improving transmission efficiency and equipment stability.

[0012] Optionally, the rotation drive source is a motor, and the rotation drive assembly further includes a clutch drive plate and a clutch driven plate. The clutch drive plate is sleeved on the output shaft of the motor, and the output shaft of the motor can drive the clutch drive plate to rotate. The clutch driven plate is fixedly sleeved on one of the rollers, and the output shaft of the motor is coaxially arranged with the roller. Teeth that can mesh with each other are formed on the end faces of the clutch drive plate and the clutch driven plate that are close to each other. The clutch drive plate or the motor can move towards the clutch driven plate until the teeth on the clutch drive plate and the clutch driven plate mesh.

[0013] By adopting the above technical solution, a controllable connection between the motor and the roller is achieved using a clutch structure. This allows the equipment to quickly engage or disengage power transmission when needed, improving the operational flexibility and safety of the equipment. The gear meshing design of the clutch's driving and driven discs ensures the reliability and accuracy of the transmission, while allowing axial movement of the motor or the clutch's driving disc for quick power disconnection. This also allows the carrier disc to be removed when no power source is needed, facilitating its placement and removal. After wiping, the entire carrier disc can be moved directly to the next process without having to remove the resistor sheets individually, simplifying the overall movement and storage of the resistor sheets.

[0014] Optionally, the wiping mechanism further includes an immersion container filled with anhydrous alcohol and an immersion drive assembly, the immersion drive assembly being used to drive the wiping cloth to move into the anhydrous alcohol.

[0015] By adopting the above technical solution and adding an immersion container and immersion drive component, the wiping cloth can be automatically immersed in anhydrous alcohol before cleaning, ensuring that the wiping cloth always maintains a suitable moisture state, thus improving the dissolution and cleaning effect on the surface of the resistor sheet. This design avoids the inconvenience of frequently dipping the cloth in alcohol manually, improves the automation and consistency of the cleaning process, and is particularly suitable for cleaning precision components where the amount of cleaning agent used is strictly required.

[0016] Optionally, the wiping mechanism further includes a mounting base, a conversion drive assembly, and a replacement assembly. The mounting base is a polygonal prism and includes multiple side surfaces arranged around a central axis. Multiple wiping cloths are provided, and each wiping cloth is detachably mounted on a different side surface. The lowermost side surface is the wiping surface, and one of the side surfaces adjacent to the wiping surface is the replacement surface. The conversion drive assembly is used to drive the mounting base to rotate around its central axis, so that the wiping surface becomes the replacement surface. The replacement assembly is used to replace the wiping cloth on the replacement surface.

[0017] By adopting the above technical solution, and setting up a prism-shaped mounting base and multiple detachable wiping cloths, automatic switching and replacement of the wiping cloths are achieved, ensuring cleaning power for the resistor sheets and significantly improving the continuous operation capability and cleaning efficiency of the equipment. The switching drive component rotates the mounting base, allowing new wiping cloths to be switched to the working position, while old wiping cloths are switched to the replacement position. The replacement component is responsible for removing and installing the cloths on the replacement surface, reducing downtime and making it suitable for long-term, high-volume resistor sheet cleaning tasks.

[0018] Optionally, the mounting base is fixedly provided with multiple magnets, and the wiping cloth is fixedly provided with multiple iron pieces corresponding to the magnets. The replacement component includes an adsorption base and a moving drive unit. The adsorption base is fixedly provided with multiple electromagnets corresponding to the magnets and a controller for controlling the on and off of the electromagnets. The moving drive unit is used to drive the adsorption base to move.

[0019] By adopting the above technical solution, the old wiping cloth is first removed from the mounting base. Then, the electromagnet on the adsorption base is energized to attract the clean wiping cloth. The clean wiping cloth is then moved to the replacement surface of the mounting base, where it is adsorbed onto the base. Finally, the electromagnet on the adsorption base is de-energized, allowing the adsorption base to detach from the wiping cloth. Utilizing the attraction between the magnet and the iron plate, combined with the electromagnet-controlled adsorption base, rapid and non-destructive removal and installation of the wiping cloth is achieved. This structure not only simplifies the replacement process and improves the level of automation, but also avoids mechanical damage to the wiping cloth or mounting structure, extending the service life of components. It is particularly suitable for automated cleaning equipment requiring frequent cloth replacement.

[0020] Optionally, it also includes a purging mechanism and a transmission mechanism. The purging mechanism includes an air blowing assembly, which includes an air blowing drive source, an air blowing pipe, and an air blowing nozzle. The air blowing drive source blows air onto the resistor sheet on the carrier plate through the air blowing pipe and the air blowing nozzle. The transmission mechanism is used to transfer the carrier plate from the purging mechanism to the wiping mechanism.

[0021] By adopting the above technical solution, the carrier tray is first transported by the conveying mechanism to the blowing mechanism, which blows away the dust on the resistor sheet. Then, the conveying mechanism transports the carrier tray to the wiping mechanism, which further cleans the impurities on the circumferential sidewalls of the resistor sheet. The introduction of the blowing and conveying mechanisms enables automatic handling and pre-treatment of the resistor sheet before and after cleaning. The air blowing component removes dust and particles from the surface of the resistor sheet, while the conveying mechanism transports the carrier tray between different workstations in an orderly manner, forming a complete cleaning production line. This significantly improves overall work efficiency and cleaning quality, and reduces pollution and errors caused by manual handling.

[0022] Optionally, the lower surface of the carrier plate is provided with multiple through holes, and the blowing mechanism further includes an air extraction component. The air extraction component includes an air extraction funnel and an air extraction drive source. The air blowing nozzle and the air extraction funnel are located on the upper and lower sides of the carrier plate, respectively. The air extraction drive source draws air from below the carrier plate through the air extraction funnel.

[0023] By adopting the above technical solution, an air extraction component is installed below the support plate, which works in conjunction with the air blowing component to form an airflow circulation, effectively collecting and discharging the dust generated during the cleaning process, preventing dust from flying around, preventing secondary pollution, and preventing dust accumulation inside the equipment. This design not only improves the cleanliness of the cleaning environment but also helps maintain the dryness of the resistor sheets, meeting the high requirements for dryness of finished resistor sheets.

[0024] Optionally, the purging mechanism further includes a moving drive component for driving the air nozzle and / or the carrier plate to move, so that the air driving source sequentially purifies each resistor sheet on the carrier plate.

[0025] By adopting the above technical solution, the moving drive component controls the relative movement of the air nozzle and / or the carrier plate, enabling point-to-point cleaning of each resistor element, ensuring comprehensive cleaning without omissions or blind spots. This structure enhances the targeting and uniformity of the cleaning process, making it suitable for cleaning scenarios with multiple rows and columns of resistor elements, thus improving the adaptability and cleaning effect of the equipment.

[0026] Optionally, the transmission mechanism includes a conveyor belt, a pushing assembly, and a retracting assembly. The blowing mechanism and the wiping mechanism are arranged along the transmission direction of the conveyor belt. The pushing assembly is provided in two sets, which correspond to the blowing mechanism and the wiping mechanism, respectively. The blowing mechanism also includes a movable seat, which is arranged with the conveyor belt in a direction perpendicular to the transmission direction of the conveyor belt. The pushing assembly corresponding to the blowing mechanism is used to push the carrier tray from the conveyor belt to the movable seat. The moving drive assembly includes a moving drive source and a translation drive source. The moving drive source is used to drive the air nozzle to reciprocate in a direction perpendicular to the transmission direction of the conveyor belt. The translation drive source is used to drive the movable seat to move in the transmission direction of the conveyor belt. The retracting assembly is used to push the carrier tray from the movable seat to the conveyor belt. The wiping mechanism also includes a fixed seat, which is arranged with the conveyor belt in a direction perpendicular to the transmission direction of the conveyor belt. The pushing assembly corresponding to the wiping mechanism is used to push the carrier tray from the conveyor belt to the fixed seat.

[0027] By adopting the above technical solution, the conveyor belt first transports the carrier tray to the blowing mechanism, and then the pushing component pushes the carrier tray onto the moving seat. The moving drive source drives the air nozzle to move, while the translation drive source drives the carrier tray to move. This allows the air nozzle to blow on the resistor elements one by one, while the moving seat moves the carrier tray to the unloading component. The unloading component then pushes the carrier tray back to the conveyor belt, which then transports it to the wiping mechanism. The pushing component pushes the carrier tray onto the fixed seat, where the wiping mechanism wipes the resistor elements. By setting up the conveyor belt, pushing component, and unloading component, and having them work in conjunction with the blowing and wiping mechanisms, a complete automated transmission and positioning system is constructed. The pushing and unloading components enable precise transfer of the carrier tray between the conveyor belt and the workstation, while the moving drive component ensures precise positioning and coverage during the blowing process. The overall system layout is reasonable, the operation is smooth, and the production cycle and equipment automation level are significantly improved.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. Through the coordinated work of the wiping mechanism and the carrier plate, automatic wiping of the circumferential sidewalls of the resistor sheet is achieved, ensuring that the wiping cloth can thoroughly and evenly clean the outer surface of the resistor sheet, significantly improving cleaning efficiency and consistency, reducing manual intervention, and suitable for the high-standard cleaning requirements of finished resistor sheets;

[0030] 2. The rotating mounting base of the conversion drive component allows the new wiping cloth to be switched to the working position, while the old wiping cloth is switched to the replacement position. The replacement component is responsible for removing and installing the cloth on the replacement surface, reducing downtime and making it suitable for long-term, large-volume resistor cleaning tasks.

[0031] 3. The moving drive component controls the relative movement of the air nozzle and / or the carrier plate, enabling point-to-point cleaning of each resistor element, ensuring thorough cleaning without any omissions or blind spots. Attached Figure Description

[0040] The following combination Figures 1-7 This application will be described in further detail.

[0041] This application discloses an automatic cleaning device for resistor sheets. (Refer to...) Figure 1 The automatic resistor cleaning device includes a frame 5 and a wiping mechanism 1 mounted on the frame 5. The device also includes a carrier tray 2. The wiping mechanism 1 and the carrier tray 2 work together. The carrier tray 2 holds the resistors, and the wiping mechanism 1 cleans the resistors on the carrier tray 2, thus achieving automatic cleaning of the resistors, improving cleaning efficiency, and saving manpower.

[0042] Reference Figure 2Multiple rollers 21 are rotatably mounted on the bearing plate 2, and each roller 21 is arranged radially. The rollers 21 can be made of metal, such as stainless steel or aluminum alloy, to ensure their strength. Rubber sleeves are fixedly fitted on the circumferential sidewalls of the rollers 21 to ensure their friction. Adjacent rollers 21 are used to drive multiple resistors to rotate. When the rollers 21 rotate, the resistors rotate along with them under the action of the friction force of the rollers 21.

[0043] Reference Figure 2 Multiple through holes 22 are provided on the lower surface of the bearing plate 2. In this embodiment, the bottom plate of the bearing plate 2 is a grid plate.

[0044] Reference Figure 1 The automatic resistor cleaning equipment also includes a feeding mechanism 9 and a conveying mechanism 4 mounted on the frame 5. The feeding mechanism 9 is used to feed the carrier tray 2 and transport it to the conveying mechanism 4. The conveying mechanism 4 is used to transport the carrier tray 2. The conveying mechanism 4 includes a conveyor belt 41, and the conveying direction of the conveyor belt 41 is parallel to the axis of the roller 21. The conveyor belt 41 is equipped with a detection sensor to detect whether there is a carrier tray 2 on the conveyor belt 41. If there is no carrier tray 2, the conveyor belt 41 is controlled to stop working to save energy. The detection sensor can be a pressure sensor or an infrared sensor, etc.

[0045] Reference Figure 1 The feeding mechanism 9 includes a lifting drive source 91, a feeding frame 92, a feeding drive source 93, and a feeding base 94. The feeding base 94 is fixedly mounted on the frame 5, and the feeding frame 92 is slidably mounted on the feeding base 94 in the vertical direction. The feeding frame 92 is used to place multiple carrier trays 2, so that the carrier trays 2 are arranged vertically on the feeding frame 92. The lifting drive source 91 can be a cylinder, with the cylinder seat fixedly mounted on the frame 5, and the piston rod fixedly connected to the feeding frame 92, thereby driving the feeding frame 92 to lift. The driving direction of the feeding drive source 93 is the same as the conveying direction of the conveyor belt 41, and the feeding drive source 93 is aligned with the conveyor belt 41 in the vertical direction. The feeding drive source 93 can also be a cylinder, with the cylinder seat fixedly mounted on the feeding base 94, and the piston rod used to push the carrier trays 2 onto the conveyor belt 41.

[0046] After the loading drive source 93 pushes the uppermost carrier plate 2 onto the conveyor belt 41, the lifting drive source 91 drives the loading rack 92 to rise until the second carrier plate 2 is vertically aligned with the conveyor belt 41. The loading drive source 93 then pushes the second carrier plate 2 onto the conveyor belt, and so on.

[0047] Reference Figure 1The automatic resistor cleaning equipment also includes a blowing mechanism 3 mounted on the frame 5. The blowing mechanism 3 is used to blow away dust from the resistors on the carrier plate 2. The transmission mechanism 4 can transmit the carrier plate 2 to the blowing mechanism 3 and from the blowing mechanism 3 to the wiping mechanism 1. The blowing mechanism 3 and the wiping mechanism 1 are arranged along the transmission direction of the conveyor belt 41.

[0048] Reference Figure 1 The conveying mechanism 4 also includes a pushing assembly 42, of which two sets are provided, corresponding to the blowing mechanism 3 and the wiping mechanism 1, respectively. The blowing mechanism 3 includes a movable seat 34, which is arranged along the arrangement direction of each roller 21 with the conveyor belt 41. The pushing assembly 42 includes a pushing drive source 421 and a pushing component 422. The pushing drive source 421 is a cylinder, and the piston rod of the cylinder of the pushing assembly 42 corresponding to the blowing mechanism 3 is fixedly connected to the pushing component 422, which can drive the pushing component 422 to move along the arrangement direction of each roller 21, thereby pushing the carrier plate 2 on the conveyor belt 41 onto the movable seat 34. The width of the pushing component 422 is large enough that when the pushing component 422 pushes the carrier plate 2 onto the moving seat 34, one end of the pushing component 422 is still located on the conveyor belt 41, thereby blocking the movement of the carrier plate 2 behind it.

[0049] Reference Figure 1 A clamping drive source 6 is fixedly installed on the movable seat 34. The clamping drive source 6 is a cylinder, and a clamping plate 7 is fixedly connected to the piston rod of the cylinder. There are two sets of clamping drive sources 6 and clamping plates 7, which are respectively located on both sides of the movable seat 34. The two sets of clamping drive sources 6 and clamping plates 7 are arranged along the transmission direction of the conveyor belt 41. The clamping drive source 6 drives the clamping plate 7 to move towards the bearing plate 2 to clamp the bearing plate 2.

[0050] Reference Figure 1 and Figure 3 The purging mechanism 3 also includes an air blowing assembly 31, which includes an air blowing drive source 311, an air blowing pipe 312, and an air blowing nozzle 313. The air blowing drive source 311 can be a fan. The two ends of the air blowing pipe 312 are connected to the air outlet of the air blowing drive source 311 and the air blowing nozzle 313, respectively. The air blowing drive source 311 blows air onto the resistor sheet on the carrier plate 2 through the air blowing pipe 312 and the air blowing nozzle 313.

[0051] Reference Figure 1 and Figure 3The blowing mechanism 3 also includes an air extraction assembly 32, which is mounted on the movable base 34. The air extraction assembly 32 includes an air extraction funnel 321 and an air extraction drive source 322. The air extraction port of the air extraction drive source 322 is connected to the outlet of the air extraction funnel 321. The blowing nozzle 313 and the air extraction funnel 321 are located on the upper and lower sides of the support plate 2, respectively. The air extraction drive source 322 can be a vacuum pump, which draws air from below the support plate 2 through the air extraction funnel 321. In other embodiments, the air extraction assembly 32 may be omitted; instead, a receiving plate may be added to the bottom of the support plate 2, and clean water may be added to the receiving plate so that the blown-off dust falls into the clean water.

[0052] Reference Figure 1 and Figure 3 The purging mechanism 3 also includes a motion drive assembly 33, which includes a motion drive source 331 and a translation drive source 332. The motion drive source 331 is a cylinder, and its piston rod is fixedly connected to the air nozzle 313, used to drive the air nozzle 313 to reciprocate along the arrangement direction of each roller 21. The translation drive source 332 is also a cylinder, and its piston rod is fixedly connected to the moving seat 34, used to drive the moving seat 34 to move along the transmission direction of the conveyor belt 41. This design makes the movement path of the air nozzle 313 relative to the moving seat 34 S-shaped, ensuring that each resistor can be purged, while the moving seat 34 can gradually move out of the area where the pusher assembly 42 is located during purging. In other embodiments, the motion drive source 331 and the translation drive source 332 can both be used to drive the air nozzle 313, and the motion drive source 331 and the translation drive source 332 can both be used to drive the moving seat 34.

[0053] Reference Figure 1 The conveying mechanism 4 also includes an unloading assembly 43. The translation drive source 332 can drive the moving seat 34 to move to the area where the unloading assembly 43 is located. The blowing mechanism 3 and the unloading assembly 43 are arranged along the conveying direction of the conveyor belt 41, and the unloading assembly 43 is located between the blowing mechanism 3 and the wiping mechanism 1. The unloading assembly 43 includes an unloading drive source 431 and an unloading component 432. The unloading drive source 431 is a cylinder, and the piston rod of the cylinder is fixedly connected to the unloading component 432, which can drive the unloading component 432 to move along the arrangement direction of each roller 21, thereby pushing the carrier plate 2 on the moving seat 34 onto the conveyor belt 41.

[0054] Reference Figure 1 and Figure 4 The wiping mechanism 1 also includes a fixed base 19, which is arranged along the arrangement direction of each roller 21 with the conveyor belt 41, and is fixedly mounted on the frame 5. The piston rod of the cylinder of the pushing component 42 corresponding to the wiping mechanism 1 is fixedly connected to the pushing component 422, which can drive the pushing component 422 to move along the arrangement direction of each roller 21, thereby pushing the carrier plate 2 on the conveyor belt 41 onto the fixed base 19.

[0055] Reference Figure 1 The fixed base 19 is also equipped with a clamping drive source 6 and a clamping plate 7, which is the same as the movable base 34, and will not be described in detail here.

[0056] Reference Figure 1 Two baffles 8 are fixedly installed on the conveyor belt 41, which correspond to the two pusher components 42 respectively. The baffles 8 are used to block the carrier plate 2, so that the carrier plate 2 can be conveyed by the conveyor belt 41 to be aligned with the pusher component 422, and prevent the carrier plate 2 from being conveyed forward by the conveyor belt 41.

[0057] Reference Figure 1 and Figure 5 The wiping mechanism 1 includes a rotation drive assembly 13, which includes sprockets 132 and chains 133. Multiple sprockets 132 are provided, each sprocket 132 being fixedly mounted on a different roller 21. The chain 133 sequentially passes around and meshes with each sprocket 132. In other embodiments, belts and pulleys can be used instead of chains 133 and sprockets 132.

[0058] Reference Figure 1 and Figure 6 The rotation drive assembly 13 also includes a rotation drive source 131, a clutch drive plate 134, and a clutch driven plate 135. The rotation drive source 131 is a motor. The clutch drive plate 134 is mounted on the output shaft of the motor via a key and keyway, allowing the output shaft of the motor to drive the clutch drive plate 134 to rotate. The clutch driven plate 135 is fixedly mounted on one of the rollers 21. The output shaft of the motor is coaxially arranged with the roller 21. The end faces of the clutch drive plate 134 and the clutch driven plate 135 that are close to each other have teeth that can mesh with each other.

[0059] Reference Figure 1 and Figure 6The rotation drive assembly 13 also includes a disengagement drive source 136 and a transmission component 137. The disengagement drive source 136 is a motor, and the output shaft of the motor extends vertically. The output shaft of the motor is fixedly connected to the transmission component 137, thereby causing the transmission component 137 to swing. The transmission component 137 is fork-shaped and is fitted onto the circumferential sidewall of the clutch drive plate 134. Two limiting plates are protruding from the clutch drive plate 134 and are arranged along the central axis of the clutch drive plate 134. The transmission component 137 is located between the two limiting plates. When the transmission component 137 swings, it can push the limiting plates, thereby causing the clutch drive plate 134 to slide axially along the output shaft of the motor. The clutch drive plate 134 can move towards the clutch driven plate 135 until the teeth on the clutch drive plate 134 and the clutch driven plate 135 are engaged. The clutch drive plate 134 can also move away from the clutch driven plate 135 until the teeth on the clutch drive plate 134 and the clutch driven plate 135 are disengaged.

[0060] When the motor starts, it transmits power to the rollers 21 through the clutch, and then drives all the rollers 21 to rotate synchronously in the same direction through the transmission of the sprocket 132 and the chain 133.

[0061] Reference Figure 1 and Figure 4 The wiping mechanism 1 also includes a wiping cloth 12, an immersion container 14 containing anhydrous alcohol, an immersion drive assembly 15, and a mounting base 16. The immersion container 14 and the conveyor belt 41 are arranged along the arrangement direction of each roller 21. The immersion drive assembly 15 includes a moving electric cylinder 151 and a lifting electric cylinder 152. The cylinder seat of the moving electric cylinder 151 is fixedly mounted on the frame 5, and the nut is fixedly connected to the cylinder seat of the lifting electric cylinder 152, thereby driving the lifting electric cylinder 152 to move along the arrangement direction of each roller 21. The nut rod of the lifting electric cylinder 152 is fixedly connected to the mounting base 16, thereby driving the mounting base 16 to rise and fall. The mounting base 16 is used for mounting the wiping cloth 12. When it is necessary to immerse the wiping cloth 12, the immersion drive assembly 15 drives the mounting base 16 to move, so that the wiping cloth 12 is immersed in anhydrous alcohol.

[0062] The wiping cloth 12 is usually made of a soft and absorbent material, such as cotton or non-woven fabric, or other cleaning cloths with similar functions can be used.

[0063] Reference Figure 1 and Figure 4The wiping mechanism 1 also includes a wiping drive assembly 11, which drives the wiping cloth 12 to move above the carrier plate 2. In this embodiment, the wiping drive assembly 11 is the immersion drive assembly 15, and the immersion container 14 and the fixed seat 19 are arranged along the arrangement direction of each roller 21, with the immersion container 14 located on the side of the fixed seat 19 away from the conveyor belt 41. In other embodiments, the wiping drive assembly 11 can be set independently of the immersion drive assembly 15.

[0064] Reference Figure 4 and Figure 7 The wiping mechanism 1 also includes a conversion drive assembly 17. The mounting base 16 is a polygonal prism, such as a regular triangular prism, and includes multiple side surfaces arranged around a central axis. Multiple wiping cloths 12 are provided, each detachably mounted on a different side surface. The lowest side surface is the wiping surface 161, and one of the side surfaces adjacent to the wiping surface 161 is the replacement surface 162. The conversion drive assembly 17 includes a motor, a belt, and two pulleys. One pulley is fixedly mounted on the output shaft of the motor, and the other pulley is fixedly connected to the mounting base 16. The pulley passes over both pulleys. The motor drives the mounting base 16 to rotate around its central axis via the belt and pulleys, causing the wiping surface 161 to become the replacement surface 162.

[0065] Reference Figure 4 and Figure 7 Each side surface of the mounting base 16 is fixedly equipped with multiple magnets 163. In this embodiment, each side surface is provided with four magnets 163, and the four magnets 163 are distributed at the four corners of the side surface. Similarly, multiple iron pieces 121 corresponding one-to-one with the magnets 163 are fixedly installed on the wiping cloth 12. The iron pieces 121 can be bent to clamp the four corners of the wiping cloth 12, and then the two bent surfaces of the iron pieces 121 and the wiping cloth 12 (not shown in the figure) are fixed by rivets or other structures.

[0066] Reference Figure 4 and Figure 7 The wiping mechanism 1 also includes a replacement component 18, which can replace the wiping cloth 12 on the replacement surface 162. The replacement component 18 includes an adsorption seat 181 and a movement drive unit 182. Multiple electromagnets 183, each corresponding to a magnet 163, and a controller for controlling the on / off state of the electromagnets 183 are fixedly mounted on the adsorption seat 181. The movement drive unit 182 is a six-degree-of-freedom robot capable of driving the adsorption seat 181 to move. The magnetic field generated by the electromagnet 183 is greater than that of the magnet 163; that is, the magnetic force exerted by the electromagnet 183 on the iron sheet 121 is greater than that exerted by the magnet 163 on the iron sheet 121.

[0067] When replacing the wiping cloth 12 on the replacement surface 162, the moving drive unit 182 drives the suction seat 181 to move onto the wiping cloth 12 on the replacement surface 162. The controller controls the electromagnet 183 to be energized, and the electromagnet 183 attracts the iron piece 121. Overcoming the magnetic force between the magnet 163 and the iron piece 121, the wiping cloth 12 is removed. After the moving drive unit 182 drives the suction seat 181 to a suitable position, the controller controls the electromagnet 183 to be de-energized, causing the old wiping cloth 12 to fall off. The moving drive unit 182 drives the suction seat 181 to move above the new wiping cloth 12. The controller controls the electromagnet 183 to be energized, and the electromagnet 183 attracts the iron piece 121. The moving drive unit 182 drives the suction seat 181 to move onto the replacement surface 162, causing the magnet 163 to attract the iron piece 121. The controller controls the electromagnet 183 to be de-energized, and the moving drive unit 182 can drive the suction seat 181 to smoothly detach from the wiping cloth 12, realizing the replacement of the wiping cloth 12.

[0068] In other embodiments, the wiping cloth 12 can be installed by clipping or securing it to the mounting base 16 for easy replacement.

[0069] In other embodiments, the drive source can be any of the following: electric cylinder, electric actuator, pneumatic cylinder, hydraulic cylinder, etc.

[0070] Reference Figure 1 The automatic resistor cleaning equipment also includes a feeding mechanism 100 mounted on the frame 5. The feeding mechanism 100 includes a feeding drive assembly 110 and a placement assembly 120. The feeding drive assembly 110 includes a front and rear drive source 111, a vertical drive source 112, a rotary drive source 113, a clamping drive source 114, and a gripper 115. The clamping drive source 114 can be a double-headed cylinder, which drives the gripper 115 to open or close, so that the gripper 115 can clamp or release the carrier plate 2. The rotary drive source 113 is a motor, and the output shaft of the motor is fixedly connected to the cylinder seat of the clamping drive source 114, thereby driving the clamping drive source 114 to rotate the gripper 115 by 180°. The vertical drive source 112 is a cylinder, and the piston rod is fixedly connected to the motor seat of the rotary drive source 113, thereby driving the gripper 115 to rise and fall. The front and rear drive sources 111 are cylinders, and the cylinder seats are fixedly mounted on the frame 5. The piston rod is fixedly connected to the cylinder seat of the vertical drive source 112, thereby driving the gripper 115 to move along the conveying direction of the conveyor belt 41.

[0071] Reference Figure 1The placement assembly 120 includes a feeding rack 121 and a feeding drive source 122 (similar to the loading rack 92 and the lifting drive source 91). The fixed base 19 and the feeding rack 121 are arranged along the conveying direction of the conveyor belt 41. The feeding rack 121 is used to place multiple carrier trays 2, such that each carrier tray 2 is arranged vertically on the feeding rack 121. The feeding drive source 122 can be a cylinder, with the cylinder seat fixedly mounted on the frame 5. The piston rod is fixedly connected to the feeding rack 121, thereby driving the feeding rack 121 to rise and fall.

[0072] When the carrier plate 2 needs to be unloaded, the front and rear drive sources 111 drive the gripper 115 to move, so that the gripper 115 moves above the fixed base 19. The vertical drive source 112 drives the gripper 115 to descend. The clamping drive source 114 drives the gripper 115 to clamp the carrier plate 2 on the fixed base 19. The vertical drive source 112 drives the gripper 115 to rise. The rotation drive source 113 drives the gripper 115 to rotate 180°. The front and rear drive sources 111 drive the gripper 115 to move, so that the gripper 115 moves above the fixed base 19. 15 moves above the unloading rack 121. The vertical drive source 112 drives the gripper 115 to descend, and the clamping drive source 114 drives the gripper 115 to release the carrier plate 2, placing the carrier plate 2 on the unloading rack 121. The vertical drive source 112 drives the gripper 115 to rise, and the front and rear drive source 111 drives the gripper 115 to move, causing the gripper 115 to exit the area of ​​the unloading rack 121. The rotation drive source 113 drives the gripper 115 to rotate 180°, causing the gripper 115 to rotate and reset. After the unloading drive assembly 110 moves the carrier plate 2 on the fixed seat 19 to the unloading rack 121, the unloading drive source 122 drives the unloading rack 121 to rise to the second placement position of the carrier plate 2, aligning it vertically with the fixed seat 19. The unloading drive assembly 110 continues to move the carrier plate 2 on the fixed seat 19 to the second placement position of the carrier plate 2 on the unloading rack 121.

[0073] The implementation principle of the automatic cleaning device for resistor sheets in this application embodiment is as follows: First, multiple manual laborers place the carrier trays 2 containing resistor sheets onto the loading rack 92. The loading drive source 93 pushes the carrier trays 2 onto the conveyor belt 41, which then transports them to an alignment with the moving seat 34. The pushing component 42 pushes the carrier trays 2 onto the moving seat 34, and the clamping drive source 6 drives the clamping plate 7 to clamp the carrier trays 2. The blowing drive source 311 starts working, and at the same time, the moving drive component 33 drives the blowing nozzle 313 and the moving seat 34 to move, so that the blowing nozzle 313 blows on the resistor sheets one by one. At the same time, the suction component 32 works. The translation drive source 332 drives the moving seat 34 to move to an alignment with the unloading component 43, which pushes the carrier trays 2 onto the conveyor belt 41. The conveyor belt 41 transports the carrier trays 2 to an alignment with the fixed seat 19, and the pushing component 42 pushes the carrier trays 2 onto the fixed seat 19. The immersion drive assembly 15 moves the mounting base 16 until the wiping cloth 12 on the wiping surface 161 is immersed in anhydrous alcohol. The wiping drive assembly 11 then moves the mounting base 16 until the wiping cloth 12 on the wiping surface 161 is directly above the carrier plate 2. The rotation drive assembly 13 drives the roller 21 to rotate synchronously in the same direction, causing the resistor to rotate, so that the wiping cloth 12 wipes the circumferential sidewalls of the resistor. After wiping, the mounting base 16 resets, and the switching drive assembly 17 drives the mounting base 16 to rotate, so that the wiping surface 161 becomes the replacement surface 162. The above operation is repeated to clean the resistor on the next carrier plate 2. While the wiping cloth 12 on the wiping surface 161 wipes the resistor, the replacement assembly 18 replaces the wiping cloth 12 on the replacement surface 162. After wiping, the unloading mechanism 100 unloads the carrier plate 2 from the fixed base 19.

[0074] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
